摘要： An electrical appliance includes an appliance base, a cover, power lines carrying electrical power to the appliance base, an interlock switch, and a fastener. The interlock switch has a switch case and a switch within the switch case. The switch case is affixed to the appliance base, the switch is in one of the power lines, and the switch has an open position and a closed position. The fastener is arranged to fasten the cover to the appliance base so that the fastener holds the switch in its closed position when the cover is fastened by the fastener to the appliance base and allows the switch to move to its open position when the cover is not fastened by the fastener to the appliance base.

摘要： A commercial microwave oven having a plurality of operator actuable switches each of which is dedicated to activating the microwave oven for a corresponding programmed time period. These operator actuable switches are located on a switchboard, and a front faceplate has graphic keypads indicating where to push to activate the respective switches. Also located on the switchboard are operator actuable switches used to reprogram the time periods, but these reprogramming switches are hidden because they do not have corresponding keypads on the faceplate. Accordingly, access to the reprogramming feature is limited to those who have been appropriately instructed.
摘要翻译：一种商用微波炉，其具有多个操作者致动开关，每个开关专用于在相应的编程时间段内启动微波炉。这些操作员可启动开关位于配电板上，前面板具有图形键盘，指示在哪里推动以激活相应的开关。交换机上还有操作员可用的开关，用于重新编程时间段，但这些重新编程开关是隐藏的，因为它们在面板上没有相应的键盘。因此，重新编程功能的访问仅限于已被适当指导的人员。

摘要： A gas cook-top with a glass top wherein each of a plurality of burners has a neck portion with a flange that seats down on a gasket thereby sealing the burner to the glass top. A collar surrounds the neck portion of each burner. Brackets are positioned below the glass top and support the burners independent of the glass top. A grate covers a pair of burners and has locator rod members that encircle portions of the respective collars, thereby fixedly locating the grate on the glass top.
摘要翻译：一种具有玻璃顶部的燃气灶顶，其中多个燃烧器中的每一个具有颈部，其具有在垫圈上向下安置的凸缘，从而将燃烧器密封到玻璃顶部。衣领环绕每个燃烧器的颈部。托架位于玻璃顶部的下方，并且独立于玻璃顶部支撑燃烧器。炉栅覆盖一对燃烧器，并且具有环绕各个套环的部分的定位杆构件，从而将炉栅固定在玻璃顶部上。

摘要： An oven door has an RF choke, an outer choke cover, first and second inner choke cover members, and a contaminant barrier The RF choke has a first side which is oriented away from a cooking chamber of an oven, and the RF choke has a second side which is oriented toward a cooking chamber of an oven. The outer choke cover abuts the first side of the RF choke. The first inner choke cover member has a gasket, and the first inner choke cover member is microwave safe. The contaminant barrier abuts the gasket of the first inner choke cover member. The second inner choke cover member abuts the contaminant barrier so that the contaminant barrier is sandwiched between the first and second inner choke cover members. The second inner choke cover member is microwave safe.
摘要翻译：烤箱门具有RF扼流器，外阻风罩，第一和第二内阻挡盖构件以及污染屏障。RF扼流器具有远离烹饪室的第一侧，RF扼流圈具有第二面朝向烤箱的烹饪室。外部扼流圈邻接RF扼流器的第一侧。第一内阻塞盖具有垫圈，第一内阻塞盖构件是微波安全的。污染物阻挡物邻接第一内阻塞盖构件的垫圈。第二内阻挡盖构件邻接污染物屏障，使得污染物屏障夹在第一和第二内阻挡盖构件之间。第二个内阻塞盖是微波安全的。
