In addition, in an embodiment, the thermistor assembly further includes a thermistor in addition to the aforementioned mounting structure of the thermistor, the thermistor includes a bottom plate (not shown) and a temperature probe 300 mounted on the bottom plate, and after the temperature probe 300 passes through the first through hole 230, the bottom plate is detachably connected to the rear plate surface and the inner container 100.

It should be noted that the mounting structure of the thermistor is particularly suitable for use in household appliances such as disinfection cabinets having an inner container 100 and requiring precise temperature control. In a common disinfection cabinet in the market at present, a thermistor for measuring temperature can be mounted on the top wall or the side wall of an inner container 10, and the mounting mode of the thermistor is usually that the thermistor is directly fixed with the inner container 10 by using bolts and nuts, specifically as shown in fig. 1, firstly, a large hole, a small hole and a large hole are drilled on the inner container 10; then, the temperature measuring probe 30 of the thermistor passes through the big hole from the outer side surface of the inner container 10 and extends into the inner container 10; then, the small hole formed on the inner container 10 is accurately aligned with the hole on the bottom plate of the thermistor on the inner side surface of the inner container 10, and then a special tool is used for driving a screw into the inner side surface to complete the fixed installation of the thermistor, so that the assembly mode is complex and the operation is very troublesome.

Based on the structural design, in the embodiment, since the mounting base 200 is provided, and the thermistor can be fixedly mounted on the inner container 100 through the mounting base 200, when in actual mounting, the fixture block 220 can be correspondingly inserted into the first mounting hole 110, and then the fixture block 220 is rotated along the preset direction, so that the hole edge of the first mounting hole 110 is clamped between the clamping portion 222 and the notch 211, the substrate 210 covers the first mounting hole 110, and when the rotation is in place, the hole inner wall of the first mounting hole 110 is abutted to the joint of the clamping portion 222 and the inner wall surface of the notch 211; then, after the temperature measuring probe 300 passes through the first through hole 230 from the outer side surface of the inner container 100, the bottom plate, the rear plate surface and the inner container 100 can be detachably connected, so that the installation of the thermistor can be conveniently completed, in other words, the installation structure of the thermistor only needs to install the installation seat 200 from one side of the outer side surface of the inner container 100, then the installation seat 200 is rotated to a preset clamping position, and then the installation seat 200 can be fixed while the thermistor is fixed by using screws and the like, so compared with the existing mode of fixedly installing the thermistor from the inner side surface and the outer side surface of the inner container 100 by using special tools, bolts, nuts and the like, the operation of the installation structure of the thermistor is simple and convenient, and the installation convenience of the thermistor is greatly improved.

Further, referring to fig. 3 and 4, in the present embodiment, the notch 211 is formed in a flaring shape gradually expanding from the connecting portion 221 toward the outer edge of the substrate 210. Specifically, the clamping portion 222 has a second side end surface opposite to the second inner wall surface 213, the second side end surface is parallel to the second inner wall surface 213 at an interval, and a gap is formed between the second side end surface and the second inner wall surface 213 along the width direction of the fixture block 220; the first inner wall surface 212 is inclined in a direction away from the second inner wall surface 213 in the longitudinal direction of the latch 220. Thus, when the mounting base 200 rotates, the hole edge of the first mounting hole 110 can be just clamped into the gap between the clamping portion 222 and the notch 211, and the flaring of the notch 211 can enable the mounting base 200 to be blocked only by the friction force of one side of the clamping portion 222 in the rotating process, thereby being beneficial to reducing the rotating resistance of the mounting base 200; in this embodiment, the second inner wall surface 213 is inclined such that after the mounting base 200 is rotated to a certain position, the hole edge of the first mounting hole 110 abuts against the joint of the clamping portion 222 and the second inner wall surface, and the area of the substrate 210 adjacent to the second inner wall surface just covers the hole edge of the first mounting hole 110 for abutment. Here, to facilitate the insertion of the latch 220 through the first mounting hole 110, the first mounting hole 110 is adapted to the shape of the latch 220, and preferably has a width slightly larger than that of the latch 220. In addition, as shown in fig. 3 and 4, in the present embodiment, the base plate 210 and the latch 220 are preferably integrally formed. For example, the mounting seat 200 made of plastic material may be integrally formed by injection molding, but in other embodiments, the latch 220 and the base plate 210 may be separately disposed and then connected.

Further, referring to fig. 2 to 4, in the present embodiment, the connection portion 221 is annular, and the diameter of the outer wall of the connection portion 221 is greater than the width of the clamping portion 222. Of course, in other embodiments, the connecting portion 221 may also be the same as the width of the fastening portion 222, that is, the fastening block 220 is in a long strip shape, but in this embodiment, the design that the diameter of the connecting portion 221 is greater than the width of the fastening portion 222 is not only beneficial to the arrangement of the first mounting hole 110, but also beneficial to avoiding material waste by designing the fastening portion 222 to be narrower. Here, in order to facilitate the penetration of the temperature probe 300 through the first through hole 230, it is preferable that the diameter of the first through hole 230 is larger than that of the straight-bar-shaped temperature probe 300.

Further, as shown in fig. 2 and 4, in the present embodiment, the length of the catching portion 222 is shorter than the outer edge of the substrate 210. Certainly, in other embodiments, the free end of the clamping portion 222 may be flush with the outer edge of the substrate 210, but in this embodiment, after the mounting seat 200 is rotated to the proper position, the portion of the substrate 210 extending out of the clamping portion 222 will be attached to the area of the back surface of the inner container 100 adjacent to the first mounting hole 110, so as to avoid the occurrence of a gap between the outer edge of the substrate 210 and the hole edge of the first mounting hole 110, and to improve the mounting sealing performance of the mounting structure of the thermistor.

Further, as shown in fig. 3 and 4, in the present embodiment, a groove 214 for holding fingers is further provided on an outer edge of the substrate 210. Specifically, the substrate 210 is designed like a rectangle, wherein a notch 211 is formed on each of two adjacent side edges, and a groove 214 is formed on each of the other two adjacent side edges. Thus, during actual installation, an assembler can hold the groove 214 with fingers to pass the latch 220 through the first mounting hole 110, and then conveniently rotate the substrate 210 in place according to a predetermined direction, so as to further improve the installation convenience of the thermistor mounting structure.

Referring to fig. 2 to 4, in order to facilitate the installation of the thermistor, in the present embodiment, a second through hole (not shown) is formed on the bottom plate at both sides of the temperature measuring probe 300, and a third through hole 215 is formed on the substrate 210 corresponding to the second through hole; the mounting structure of the thermistor further includes a connecting member 400, and the connecting member 400 is connected to the inner container 100 after sequentially passing through the second through hole and the third through hole 215. Specifically, still be equipped with the second mounting hole 120 that supplies connecting piece 400 to wear out on the inner bag 100, the screw of the high and corrosion-resistant stainless steel of preferred intensity of connecting piece 400, after the mount pad 200 rotated to the position, the screw just can be very convenient wear to establish second through-hole and third through-hole 215 in proper order, then realize the spiro union with inner bag 100 through second mounting hole 120 to realize the further fixed of mount pad 200 on inner bag 100 simultaneously. However, the design is not limited thereto, and in other embodiments, the bottom plate and the rear plate surface of the substrate 210 may be connected by, for example, but not limited to, clamping.

Here, as shown in fig. 2, for facilitating the installation of the screw and avoiding the troublesome precise alignment operation, the second mounting hole 120 is preferably communicated with the first mounting hole 110, so that, after the mounting seat 200 is rotated in place, the second mounting hole 120 can be just corresponding to and communicated with the second through hole and the third through hole 215, so that the connecting member 400 such as the screw can be conveniently installed, and the free end of the connecting member 400 is lower than the front side surface of the fixture block 220, thereby avoiding the occurrence of the collision and bruise caused by the excessively protruding free end of the connecting member 400.

The invention further provides a household appliance which can be but not limited to a disinfection cabinet, a dishwasher and the like, the household appliance comprises a thermistor mounting structure, the specific structure of the thermistor mounting structure refers to the embodiments, and the household appliance adopts all the technical schemes of all the embodiments, so that all the beneficial effects brought by the technical schemes of the embodiments are also achieved, and the description is omitted.
