[0031] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the following provides a further detailed description of the technical solutions of the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.
[0032] In the description of this application, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0033] In this application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature can include the direct contact between the first and second features, or can also include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is less than that of the second feature.
[0034] Some existing washing machines have the function of automatically dispensing detergent, which is specifically achieved by setting a detergent box, a peristaltic pump, etc. Users can pre-store the detergent in the detergent box. When starting the laundry, the peristaltic pump automatically pumps an appropriate amount of detergent from the detergent box into the laundry tub. To achieve the function of automatically reminding users to add detergent in time when the detergent is exhausted, a transfer box connected between the detergent box and the peristaltic pump is also integrated in the existing automatic dispensing system. A liquid level detector is provided in the transfer box, and the liquid level detector is connected to the control center of the washing machine. When it detects that the liquid level of the liquid level detector is too low, the control center can automatically remind the user to add detergent. Although the existing automatic detergent dispensing system of the washing machine can achieve the automatic reminder function, the structure of adding a transfer box to set the liquid level detector has complicated the structure of the automatic dispensing system, resulting in the problem of a relatively high cost of the automatic dispensing system.
[0035] To overcome the above technical problems, refer to Figure 1-3, this embodiment provides a detergent box installation structure, including a detergent box 1, a liquid level detector 4, and a detergent box fixing base 2; the detergent box 1 is used to store detergent; the liquid level detector 4 is installed in the detergent box 1 and is used to detect the liquid level height in the detergent box 1; the liquid level detector 4 has a first contact terminal 41, and the first contact terminal 41 extends through and out from the bottom of the detergent box 1; the detergent box fixing base 2 is provided with a second contact terminal 3 corresponding to the first contact terminal 41, and the second contact terminal 3 is electrically connected to the control center of the washing machine; the detergent box 1 is installed on the detergent box fixing base 2, and the first contact terminal 41 contacts the second contact terminal 3.
[0036] Among them, the detergent box fixing base 2 is used to fix the detergent box 1, and it is generally connected and fixed to the frame or casing of the washing machine. The detergent box 1 is a separately assembled structure, and existing washing machines are equipped with a fixing base structure for it. Therefore, setting the detergent fixing base in this solution does not complicate the component structure of the washing machine.
[0037] Based on the detergent box installation structure of this embodiment, a liquid level detector 4 is provided in the detergent box 1. In the case of realizing the function of automatically detecting the liquid level and reminding the user to add detergent, there is no need to add a transfer box. Compared with the traditional solution, the structure is simplified and the cost is reduced.
[0038] Although setting the liquid level detector 4 for the detergent box 1 can directly detect the detergent stock in the detergent box 1 to eliminate the structure of the transfer box, the liquid level detector 4 needs to establish an electrical connection relationship with the control center of the washing machine. When installing the detergent box 1 or performing maintenance and disassembly of the detergent box 1, it is necessary to perform circuit connection or disconnection work, resulting in the problem of difficult disassembly and assembly of the detergent box 1.
[0039] To overcome the above problems, this embodiment provides a solution idea: the first contact terminal 41 of the liquid level detector 4 extends out from the bottom of the detergent box 1, and a second contact terminal 3 corresponding to the first contact terminal 41 is provided on the detergent box fixing base 2 in the washing machine. During the installation process of the detergent box 1, when the detergent box 1 is inserted and fixed to the detergent box fixing base 2, the first contact terminal 41 contacts the second contact terminal 3, that is, the electrical connection operation of the liquid level detector 4 is completed synchronously, without the need for additional wiring operations. When it is necessary to remove the detergent box 1 for maintenance, the detergent box 1 can be directly pulled out without the need for wire disconnection operations. Therefore, the detergent box installation structure provided by this embodiment not only has the advantage of simple structure, but also has the advantage of convenient installation.
[0040] In one embodiment, refer to Figure 4, the detergent box fixing base 2 includes a base plate 21 and a surrounding wall 22 provided on the top side of the base plate 21. The base plate 21 and the surrounding wall 22 enclose an installation slot, and the detergent box 1 is inserted into the installation slot for fixation; the second contact terminal 3 is provided on the base plate 21.
[0041] The base plate 21 is the main supporting part of the detergent box fixing base 2. It is fixedly connected to the frame or casing of the washing machine, providing a stable installation foundation. The surrounding wall 22 is provided on the top side of the base plate 21 and together with the base plate 21 encloses an installation slot. This installation slot matches the shape of the detergent box 1 to ensure that the detergent box 1 can be firmly inserted therein. The second contact terminal 3 is provided on the base plate 21 and corresponds to the first contact terminal 41 inside the detergent box 1. When the detergent box 1 is inserted into the installation slot, the first contact terminal 41 and the second contact terminal 3 will automatically come into contact, thereby realizing the electrical connection between the liquid level detector 4 and the washing machine control center. Through the installation slot formed by enclosing the base plate 21 and the surrounding wall 22 in this solution, it can be ensured that the detergent box 1 remains stable during the operation of the washing machine, preventing it from shaking or shifting. The design of the installation slot makes the insertion and removal of the detergent box 1 very simple.
[0042] In one embodiment, referring to Figure 2 , a plurality of buckle grooves 11 are circumferentially provided on the outer side wall of the detergent box 1; a plurality of rib plates 23 extending upward are provided on the top side of the surrounding wall 22. The rib plates 23 are provided with protruding buckles 231 opposite to the buckle grooves 11, and the protruding buckles 231 are buckled with the buckle grooves 11 to limit the detergent box 1 from disengaging from the installation slot.
[0043] The buckling mechanism of the protruding buckle 231 and the buckle groove 11 ensures the stability of the detergent box 1 in the installation slot. Even during the operation of the washing machine, the detergent box 1 can maintain a stable position. At the same time, this structure has the advantage of good convenience. When the user needs to take out or replace the detergent box 1, just apply a little force to separate the protruding buckle 231 from the buckle groove 11, so as to conveniently pull out the detergent box 1 from the installation slot.
[0044] In one embodiment, referring to Figure 5 , a counterbore 211 is provided on the base plate 21, and the second contact terminal 3 is installed in the counterbore 211 so that the detergent box 1 can contact the base plate 21 after being installed.
[0045] Due to the design of the sinking groove 211, the detergent box 1 can contact the base plate 21 flatly after installation, avoiding the problem of uneven contact caused by the protrusion of the second contact terminal 3. At the same time, the sinking groove 211 provides a relatively enclosed installation environment for the second contact terminal 3, which helps to protect the contact terminal from interference and damage from the external environment (such as moisture, dust, etc.).
[0046] In one embodiment, the second contact terminal 3 includes a terminal contact 31 and an ejecting spring 32. The terminal contact 31 is connected to the ejecting spring 32, and the ejecting spring 32 can push the terminal contact 31 upward so that the terminal contact 31 can tightly press the first contact terminal 41.
[0047] Through the action of the ejecting spring 32, the terminal contact 31 can always maintain close contact with the first contact terminal 41. Even under the vibration and impact during the operation of the washing machine, a stable connection can be maintained. At the same time, due to the certain elasticity of the ejecting spring 32, it can adapt to the first contact terminals 41 of different sizes and shapes, ensuring stable connection in various situations.
[0048] In one embodiment, referring to Figure 6 , a through hole is provided at the bottom of the sinking groove 211 on the base plate 21. The terminal contact 31 is a bolt, and the threaded portion of the terminal contact 31 passes downward through the through hole and is connected to a nut 33. The ejecting spring 32 is compressed between the nut of the terminal contact 31 and the base plate 21.
[0049] The nut 33 cooperates with the threaded portion of the bolt. By rotating the nut 33, the tightening degree of the bolt can be adjusted. When the nut 33 is tightened, the ejecting spring 32 is further compressed, thereby increasing the contact pressure on the first contact terminal 41; when the nut 33 is loosened, the reaction force of the ejecting spring 32 decreases, and the contact pressure also decreases accordingly. By rotating the nut 33, the tightening degree of the bolt can be conveniently adjusted to adapt to the detergent box 1 of different sizes or the first contact terminals 41 with different pressure requirements.
[0050] In one embodiment, the base plate 21 is provided with a plurality of mounting holes, and the base plate 21 can be locked to the frame of the washing machine through the mounting holes.
[0051] The main function of the mounting holes is to firmly mount the base plate 21 on the frame of the washing machine. Through these mounting holes, screws, bolts or other fasteners can be used to tightly connect the base plate 21 to the washing machine frame. This connection method ensures that the base plate 21 will not move or shake during the operation of the washing machine, thus ensuring the stability and reliability of the detergent box 1.
[0052] In one embodiment, referring toFigure 7-8 The liquid level detector 4 includes a float 42 and two first contact terminals 41 spaced apart at the bottom of the detergent box 1. A conductive sheet 421 is provided on the float 42. When the detergent in the detergent box 1 is exhausted, the conductive sheet 421 can contact and conduct the two first contact terminals 41.
[0053] A liquid level detector 4 is provided at the bottom of the detergent box 1. The liquid level detector 4 includes two first contact terminals 41 and a float 42. A conductive sheet 421 is provided on the float 42. In application, the two first contact terminals 41 are respectively connected to the control center through two second contact terminals 3 in contact. The detergent serves as an insulating medium. When the conductive sheet 421 does not simultaneously contact the two first contact terminals 41, the control center detects that the two first contact terminals 41 are in an open state; when the conductive sheet 421 simultaneously contacts the two first contact terminals 41, the control center can detect that the two first contact terminals 41 are connected. Therefore, the detection principle of the liquid level detector 4 in this solution is achieved by judging the on / off state of the two first contact terminals 41.
[0054] Obviously, this liquid level detector 4 has the advantages of simple structure and good reliability.
[0055] In one embodiment, a guide rod 12 is erected in the detergent box 1. The float 42 is slidably connected to the guide rod 12. The guide rod 12 guides the linear lifting and lowering of the float 42, so that the float 42 can accurately contact the first contact terminal 41 after it descends.
[0056] The guide rod 12 provides a clear lifting and lowering path for the float 42, ensuring that the float 42 can lift and lower vertically without being offset due to the fluctuation or inclination of the detergent, greatly improving the accuracy of the contact between the float 42 and the first contact terminal 41.
[0057] On the other hand, this embodiment also provides a washing machine including the above-mentioned detergent box mounting structure.
[0058] Specifically, the washing machine in this embodiment further includes a frame and a casing. The detergent box fixing seat 2 is installed on the frame or the casing. The second contact terminal 3 on the detergent box fixing seat 2 is electrically connected to the control center of the washing machine. The detergent box 1 is inserted into the detergent box fixing seat 2. After insertion, the first contact terminal 41 of the liquid level detector 4 contacts the second contact terminal 3.
