[0046] Example 1

[0047] like Figure 1 As shown, the humidity detection device provided by the utility model includes: a fixing seat, a humidity detector 200 and a protective cover 300.

[0048] The fixing seat is used to connect with the inner tank 500 of the dishwasher. The fixing seat can adopt a fixed connection method, such as welding or integrally forming with the inner tank 500, or a detachable connection method, such as threaded connection or clamping.

[0049] The humidity detector 200 and the protective cover 300 are both connected to the fixing seat, and the humidity detector 200 and the protective cover 300 are both located on the inner side of the inner liner 500. The protective cover 300 is arranged on the outer side of the humidity detector 200 to prevent water from splashing onto the detection part 210 of the humidity detector 200. The protective cover 300 is provided with air holes, and air can freely enter and exit the protective cover 300. The projection of the air holes inward along the axial direction does not fall on the detection part 210 of the humidity detector 200, so as to avoid water splashing onto the detection part 210 through the air holes. The air in the inner liner 500 can enter the protective cover 300 through the air holes, and then be detected by the humidity detector 200, so as to obtain the air humidity value inside the inner liner 500. In addition, the projection of the air vent along its axial direction inward does not fall on the detection part 210 of the humidity detector 200. That is to say, water entering the protective cover 300 through the air vent will not splash onto the detection part 210, thereby avoiding the problem of reduced detection accuracy due to water sticking to the detection part 210.

[0050] In this embodiment, the vent hole and the detection unit 210 are staggered, that is, the projection of the vent hole along its axial direction toward the inner side of the protective cover 300 can fall on the inner wall of the protective cover 300, or on the fixed seat, or part of it falls on the inner wall of the protective cover 300 and part of it falls on the fixed seat. In this solution, there is no blocking structure between the detection unit 210 and the vent hole, and waterproofing is achieved simply by staggering.

[0051] Specifically, Figure 1 - Figure 6 As shown, in the first implementation of this embodiment, a mounting plate 111 is provided on the fixing seat, and the mounting plate 111 can be arranged horizontally. The mounting plate 111 has a avoidance hole 1111 penetrating the upper and lower surfaces thereof for air to pass through. The humidity detector 200 is horizontally mounted on the upper surface of the mounting plate 111, and the side wall of the humidity detector 200 has a detection hole for air to enter the inside thereof, and the detection hole forms a detection portion 210. The detection hole is aligned with the avoidance hole 1111 and faces the avoidance hole 1111. The protective cover 300 includes a bottom 310 and a side wall 320, and the bottom 310 is connected to the lower end of the side wall 320, and the upper end of the side wall 320 is connected to the fixing seat, and a snap connection method can be adopted, that is, a buckle 120 is provided on the fixing seat, and a snap hole 330 is provided on the side wall 320. The bottom 310 faces the mounting plate 111, and the two can be arranged in parallel.

[0052] An air hole may be provided on the bottom 310, and the air hole provided on the bottom 310 is the first hole 311. Because the avoidance hole 1111 faces downward, in order to prevent water splashing from the first hole 311 from passing through the avoidance hole 1111 and falling on the detection part 210, the first hole 311 is completely misaligned with the avoidance hole 1111, and water passing through the first hole 311 will fall on the mounting plate 111.

[0053] Air holes may also be provided on the side wall 320, and the air holes provided on the side wall 320 are second holes 321. The second holes 321 are located between the mounting plate 111 and the bottom 310. Because the detection part 210 is set downward, water entering the protective cover 300 from the second hole 321 will not fall on the detection part 210. Therefore, the second hole 321 can accelerate the flow of air inside and outside.

[0054] In the second implementation of this embodiment, Figure 7 - Fig. 9 As shown, the humidity detector 200 can be placed vertically in a fixed seat, the detection part 210 is at the lower end of the humidity detector 200 and is located inside the protective cover 300, and a bracket 130 supporting the humidity detector 200 is provided in the fixed seat. The bracket 130 is sealed on three circumferential sides and one side is open. The lower side of the bracket 130 has a bottom plate for supporting the humidity detector 200, and the detection part 210 is located on the open side, and the plane where the detection part 210 is located faces the side wall 320.

[0055] The bottom 310 may be provided with an air hole, and the air hole provided at the bottom 310 is the first hole 311 . Because the detection portion 210 faces the side wall 320 , water splashed from the first hole 311 below will not fall on the detection portion 210 .

[0056] The side wall 320 may also be provided with ventilation holes, and the ventilation holes located on the side wall 320 are second holes 321. The second holes 321 are completely offset from the detection unit 210. Specifically, the side wall 320 may be surrounded by four sides, front, back, left and right, the detection unit 210 may face the front, and the second holes 321 are opened on the left and right sides.

[0057] Furthermore, an inclined baffle plate 322 is provided on the inner side of the second hole 321. From top to bottom, the baffle plate 322 is inclined inward. Water splashing from the second hole 321 into the protective cover will be blocked by the baffle plate 322, then drained downward and dripped to the bottom 310 of the protective cover, and finally flowed out from the first hole 311.

[0058] The protective cover 300 is detachably connected to the fixing seat. In this embodiment, the buckle 120 and the hole 330 are used for the connection.

[0059] The fixing seat includes a seat body 110 and a locking ring 140. The top of the seat body 110 is provided with a protruding portion 112 protruding upward, the protruding portion 112 is provided with a first thread structure 710, and the locking ring 140 is provided with a second thread structure 720. The seat body 110 is located on the inner side of the inner liner 500, the protruding portion 112 penetrates the inner liner 500, and the locking ring 140 is threadedly connected with the protruding portion 112 on the outer side of the inner liner 500. In the first embodiment, the first thread structure 710 is an internal thread structure, and the second thread structure 720 is an external thread structure, while in the second embodiment, the first thread structure 710 is an external thread structure, and the second thread structure 720 is an internal thread structure. The locking ring 140 and the seat body 110 are pressed against opposite sides of the wall of the inner liner 500 under the action of the thread. In order to achieve sealing and waterproofing, a sealing ring 400 is provided between the seat body 110 and the inner liner 500.

[0060] Example 2

[0061] like Fig.10 , which is different from the first embodiment in Example 1, is that the humidity detection device further includes a partition 600, which is disposed between the air vents and the detection unit 210, and has an air guide hole 610 connecting the air vents and the detection unit 210, and the projection of the air vents inward along the axial direction falls on the partition 600. That is, in this embodiment, some of the air vents can be aligned with the detection unit 210, but since the partition 600 is disposed between the two, splashing water can also be blocked, and air can bypass the partition 600 and act on the detection unit 210 from the air guide hole 610.

[0062] The dishwasher provided by the utility model includes the above-mentioned humidity detection device. Since the dishwasher provided by the utility model uses the above-mentioned humidity detection device, the dishwasher provided by the utility model also has the advantages of the humidity detection device.

[0063] like Fig.11 and Fig.12 As shown, the humidity detection device can be installed on the top of the inner liner 500 and close to the back plate.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
