Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor structure for household appliances. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. The mounting brackets on common temperature detection and other sensing equipment can only realize one of the two installation methods of the sensor: lateral or horizontal. This limits its scope of application. Moreover, due to the lack of corresponding protection and fixed structure design, the transmission cable and the temperature probe are prone to loosening. Moreover, if the connection between the transmission cable and the sensor body is bent, it is easy to break during long-term use, making it difficult to use the temperature sensing function normally. Improvements are needed. Utility Model Content

[0034] In this embodiment, the temperature sensor structure is mainly used in household appliances (such as rice cookers). Before use, the temperature sensing element 102 passes through the limit slot 2011 on the mounting bracket 201, so that the front end of the sensor housing 101 is stepped (such as Figure 2 The portion shown in FIG. 20 is connected to the limit slot 2011 (as shown in FIG. 2011 ) adapted to its structure. Figure 3 At the same time, the transmission cable 103 is embedded into the cable sleeve 301 and the cable slot 2031 through the cable clamping notch, so as to fix and protect the transmission cable 103. Then, the end of the transmission cable 103 is electrically connected to the mainboard in the home appliance, and then installed according to the installation slot reserved in the home appliance: if it is installed sideways, the screws are passed through the positioning holes 2041 reserved in the connecting ears 204 on the connecting plate 202, and then tightened in the corresponding slots; if it is installed horizontally, the screws are passed through the positioning holes 2041 reserved in the connecting ears 204 on the mounting bracket 201, and then tightened in the corresponding slots, so as to achieve the purpose of quickly fixing the temperature sensor.

[0036] Example 2

[0037] Reference Figure 1 , 3, 4, 5 and 6 are the second embodiment of the utility model, which is different from the first embodiment in that: the cable protection assembly 300 includes a telescopic buckle 302 and a spring 303, the cable clamping notch is arranged with a telescopic buckle 302, the telescopic buckle 302 is connected with a spring 303, and is horizontally slidably connected with the protection bracket 203 through the spring 303; the inner side wall of the telescopic buckle 302 is in close contact with the transmission cable 103 in the cable clamping groove 2031; a positioning slot 2032 is provided on the cable clamping groove 2031 on one side of the cable clamping notch, and a limiting sliding groove 2033 is provided on the cable clamping groove 2031 on the other side of the cable clamping notch, The retractable buckle 302 is slidably arranged in the limiting slide groove 2033.

In this embodiment, before the transmission cable 103 is embedded in the cable sleeve 301, the operator first pulls the telescopic buckle 302 open by hand, so that the rear end of the telescopic buckle 302 gradually penetrates into the limiting slide groove 2033, and compresses the spring 303 until the wire clamping gap is exposed, and then the transmission cable 103 is embedded in the cable sleeve 301 and the cable clamping groove 2031 through the wire clamping gap, and releases the push-pull handle 3021, so that the telescopic buckle 302 is pushed outward under the action of the elastic reset function of the spring 303 itself, so that the end of the telescopic buckle 302 is embedded in the positioning slot 2032. At the same time, the inner side wall of the telescopic buckle 302 is close to the outer wall of the transmission cable 103 in the cable clamping groove 2032, preventing the transmission cable 103 and the temperature sensing element 102 from loosening, ensuring the normal use of the cable protection assembly 300 for the protection function of the transmission cable 103, and extending the service life of the temperature sensor and its supporting household appliances.

[0040] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
