摘要： PROBLEM TO BE SOLVED: To ensure reliability of sealing between a hot water plug insertion port and an inserting member while improving the appearance when the hot water plug is inserted. SOLUTION: A protective cap 12 has an inserting member where an O-ring 12a is fitted in an O-ring groove 12c made in the outer circumference at a guide part 12b. An inserting part 14b is formed on the bottom face of a slide cover 14a such that a rectangle is partially deformed arcuately and the width B is set larger than the outside diameter at the guide part 12b of the protective cap 12 and slightly smaller than the outside diameter of the O-ring 12a. Consequently, the protective cap 12 is fitted in the O-ring groove 12c and the protective cap 12 is held while being inserted into the inserting part 14b. Since the O-ring 12a is not exposed to the outside, the reliability of sealing can be improved between a hot water plug insertion port and the O-ring 12a along with the appearance.

摘要： PROBLEM TO BE SOLVED: To make the attaching work of a hot-water plug socket device easier so that the device may be fixed surely to a floor even when the floor is composed of TATAMI mat by providing a connection box for mount, a hot-water plug receiver provided in a box, and a hot-water plug detachably connected to the plug receiver.
SOLUTION: At the time of assembling a device which connects the heat-source device of a hot-water heater, etc., to a radiator and is fixed to a floor composed of TATAMI mat, etc., a connection box 14 is inserted into the box inserting hole 6 of a mount 5 and fixed to the mount 5 by screwing set screws 15 in the taped holes of a flange 14a. Then a hot-water plug receiver 17 is attached to the connection box 14 through the plug receiver attaching holes 16 of the connection box 14 and a hot-water hose 18 is connected to the receiver 17. Thereafter, the male screw section 11 of a threaded pipe 9 is meshed with the female screw section 8 of the through tapped hole 7 of the mount 5 and, while the section 11 is meshed with the section 8, the inserting section of the mount 5 is inserted into the hole 3 of TATAMI mat 1. Consequently, the flange section 5b of the mount 5 comes into contact with the surface of the TATAMI mat in such a state that the section 5b presses the periphery of the hole 3 from the surface side of the TATAMI mat. Finally, the threaded pipe 9 and mount 5 are fixed to a floor board 2.

摘要： PROBLEM TO BE SOLVED: To ensure comfortable warming suitable for sleep by eliminating the noise and the feeling of air flow. SOLUTION: When switching the operation to a 'sleep' mode, the room temperature is set at a specified temperature +α deg.C for a predetermined time and then it is set at a specified temperature +β deg.C (α>β) for next predetermined time. Subsequently, the room temperature is set at a specified temperature. 'Weak air supply' is performed when the room temperature drops below the set temperature while 'air supply stop' is performed when the room temperature exceeds the set temperature by some level and 'intermediate air supply' is performed when the room temperature drops the set temperature by some level.

摘要： PROBLEM TO BE SOLVED: To prevent shake of water in a drain tank at the time of wasting water from the drain tank by mounting a boss which defines a pivoting angle of a float on the inner wall of the drain tank. SOLUTION: Water which is condensed on an evaporator by dewing during a dehumidifying operation is stored in a drain tank 10 by way of a drain opening 8 of a drain pan 9. The water level of the water stored in the drain tank 10 can be readily read by means of a water level indication plate 16. Along with the elevation of the water level, a float 13 is lifted. When the distance between a magnet 14 which is mounted on the float 13 and a reed switch 15 which is mounted on the drain tank 10 exceeds a specified distance, the dehumidifying operation is automatically stopped so as to prevent overflow. At the time of wasting water stored in the drain tank 10, the drain tank 10 is removed from a body of a dehumidifier and then carried to a location where water is wasted by holding a handle 17. Since the pivoting of the float 13 in an upward direction is prevented by the boss 20, the water can be prevented from shaking so that shaking of the water surface can be minimized. Accordingly, spilling of water from the drain tank 10 can be prevented.

摘要： PURPOSE: To provide a combustion device which is capable of detecting oxygen deficiency by making use of the characteristics of flame currents based on the adoption of an air ratio control system. CONSTITUTION: Controlled variables of a pump 2 and a fan 3, which are required to maintain an optimum air ratio, are preliminarily set in a manufacturing process. The variables are stored in a memory means 7, thereby eliminating the need for an air ratio correction by a feedback to a combustion amount setting means 11 during normal combustion after shipping.

摘要： PURPOSE:To reduce the generation of NO2 and make a main body smaller in size by providing an air buffer wall against the swirling direction of air flow that is produced at a combustion drum outlet by the rotation of a propeller fan. CONSTITUTION:An air buffer wall 16 is installed at a place where outside air sent in by the rotation of a propeller fan 13 passes through a combustion drum outlet 11, and located on a side of the combustion drum out let 11. High temperature combustion gas is produced by a secondary flame 15 that spreads out from the combustion drum outlet 11, and air sent in by the rotation of a propeller fan 13 flows into a duct 12 through an outside air intake, is mixed with the combustion gas as it swirls, turned into warm air and discharged forward from a warm air outlet of the duct 12. At this time, as the swirling air is mixed with the secondary flame 15 after striking on the air buffer wall 16, mixing proceeds gradually and a sharp drop in the temperature of the secondary flame is prevented, so that NO produced by the secondary flame 15 is restrained from being converted into NO2. Therefore, a safety warm air heater with a smaller size can be obtained.

摘要： PURPOSE:To provide a combustion device capable of realizing a stable blue flame combustion and improving reliability in operation by a method wherein an air ratio is corrected by an ion current. CONSTITUTION:A blower control circuit device 18 may control the number of rotation of a blower 1 by varying a frequency, for example, in order to make a peak value of ion current in case of ignition and combustion. It is constructed such that a static pressure during combustion is set by a partition wall 19 to have a higher static pressure within a space 21 including a nozzle 11 than that of a combustion space 20. After ignition is confirmed by the ion current, a blower 16 is rotated and a ratio of primary air is increased. This ion current is a peak signal showing a peak value at an air ratio mu1 0.9. The number of rotation of the blower 16 is varied by a control circuit device 14 and a blower control circuit device 18, and if the number of rotation is adjusted to have a peak ion current value, a flame is formed in close contact with a flame hole 8 to enable combustion to be realized under the most suitable condition. Even in case that a louver 17 is closed during ignition or dusts are accumulated to cause an amount of air to be decreased, the number of rotation of the blower 16 is increased to enable a blue flame combustion to be realized.

摘要： PURPOSE:To enable a vaporizing chamber to be used for a long time by increasing its tar-resistant properties, by arranging a fuel feeding port and a vaporized fuel discharge port in the nearly symmetrical positions with respect to a throat therebetween on the bottom of vaporization chamber and those ports being open within the vaporizing chamber. CONSTITUTION:A liquid fuel fed by a pump through an oil feeding pipe 11 is fed into a vaporizing chamber 6 from a fuel feeding port 9. As the inside of a vaporizing chamber 6 is preheated by an electric heater 13, the fed fuel is vaporized in a moment of time. When the internal pressure of a vaporizing chamber 6 is heightened by expansion of fuel by vaporing, the vaporized fuel is ejected into a throat 2 from a suction port 10 through a nozzle 1 via a fuel introducing pipe 12. At the same time air is sucked into the throat 2 from an opening at the bottom, the fuel is mixed with the air, becoming a mixed gas in the throat 2, going up to a burner head 3, being ignited to form flames on the burner head 3. The liquid fuel feeding port 9 and the vaporized fuel discharge port 10 are formed nearly symmetrically, with respect to the throat 2 between them on the cover plate 8 of the bottom plate of a vaporizing chamber 6, with a comparatively long distance provided between them, as a result, the tar- resistant properties of the vaporizing chamber are increased.
