Detailed implementation manners

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0044] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0045] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] As Figures 1 to 12 shown, a wall-mounted device according to the present invention, the wall-mounted device includes a wall-mounted device main body 1.

[0047] The wall-mounted device is a wall-mounted washing machine, a wall-mounted dryer, a wall-mounted air conditioner, a wall-mounted boiler, a clothes dryer, etc.

[0048] The wall-mounted device is often installed on a wall to save floor space and facilitate user use. The back side of the wall-mounted device main body 1 is arranged opposite to the wall for hanging installation. When the wall-mounted device is used for a long time, there is a potential risk of loosening and falling. However, when the wall-mounted device main body 1 loosens, the user cannot know in time, and thus cannot turn off the wall-mounted device in time, nor can reinstall the wall-mounted device in time, which is not convenient for use.

[0049] Taking the wall-mounted washing machine as an example, the wall-mounted device main body 1 includes a housing, a drum module, a driving device, etc. The drum module and the driving device are integrated in the housing. One end of the wall-mounted device main body 1 is provided with an installation part 11, which is connected to the wall. Specifically, the housing includes a box body and a rear plate. One end of the rear plate is connected to the drum module, and the other end is used to connect to the wall. The driving device is installed on the rear plate and is in transmission connection with the drum module. The box body covers the drum module and is connected to the rear plate. The rear plate can also be set as a hanging ear structure connected to the drum module. The installation part 11 is an installation structure such as the rear plate or the hanging ear structure. The installation part 11 is connected to the wall through a fixing member 7, and the fixing member 7 is usually an expansion bolt.

[0050] In the wall-mounted washing machine, when the driving device drives the drum module to work, vibrations will occur. After long-term use, the fixing member 7 becomes loose from the wall, and the gap between the wall-mounted device main body 1 and the wall becomes larger, that is, the wall-mounted device main body 1 is loosely installed, and there is a risk of falling, resulting in damage to the wall-mounted device.

[0051] The wall-mounted device according to the present invention further includes a first base 2, a second base 3, and a switch 4. An installation groove 111 is provided on the back side of the wall-mounted device main body 1.

[0052] The first base 2 is arranged in the installation groove 111 and one end abuts against the bottom wall of the installation groove 111.

[0053] One end of the second base 3 is movably arranged inside the other end of the first base 2. An accommodating cavity that is internally connected is formed between the second base 3 and the first base 2. When the wall-mounted device main body 1 becomes loose during installation, the first base 2 and the second base 3 move away from each other.

[0054] The switch 4 includes a switch main body 41 and a trigger 42, which are correspondingly arranged on the first base 2 and the second base 3 inside the accommodating cavity, and are used to cooperate with the trigger of the switch 4 to generate a loosening signal when the first base 2 and the second base 3 move away from each other.

[0055] In the above solution, the switch main body 41 and the trigger 42 are respectively arranged on the first base 2 and the second base 3 inside the accommodating cavity. When the wall-mounted device main body 1 becomes loose during installation, the first base 2 and the second base 3 move away from each other, and the switch main body 41 and the trigger 42 move away from each other accordingly, triggering the switch 4 to generate a loosening signal, warning the user in time, stopping the wall-mounted device from working, and preventing the wall-mounted device from falling.

[0056] Specifically, one end of the second base 3 is arranged inside the first base 2. The first base 2 and the second base 3 are clamped between the installation part 11 and the wall. The installation part 11 is provided with the installation groove 111, the opening of the installation groove 111 faces the wall, and it extends for a certain length. The first base 2 and the second base 3 are clamped between the bottom wall of the installation groove 111 and the wall. An internally connected accommodating cavity is formed between the first base 2 and the second base 3. The switch main body 41 and the trigger 42 are respectively arranged on the first base 2 and the second base 3 inside the accommodating cavity, which can reduce the overall size between the first base 2 and the second base 3, reduce the installation space, and facilitate installation.

[0057] When the wall-mounted device main body 1 is fixed to the wall, the switch 4 is connected or disconnected.

[0058] When the main body 1 of the wall-mounted device becomes loose during installation, the first base 2 and the main body 1 of the wall-mounted device move away from the wall together. The second base 3 abuts against the wall, and the first base 2 and the second base 3 move away from each other. The switch main body 41 and the trigger member 42 move away from each other. The total distance that the switch main body 41 and the trigger member 42 move away from each other is the same as the distance that the main body 1 of the wall-mounted device moves. After moving a certain distance, the switch 4 is triggered to generate a loosening signal. The wall-mounted device is provided with a receiving device for receiving the loosening signal, timely shutting down the working power supply of the wall-mounted device, stopping its operation and sending a warning message or giving an alarm to a user's mobile phone, tablet or other terminal, so as to give a warning to the user in time. A warning structure such as a buzzer or an indicator light can also be set. When the receiving device receives the loosening signal, it controls the warning structure to work and gives a warning to the user in time.

[0059] The installation groove 111 can be set in the shapes of a triangle, a square, a circle, etc.

[0060] Preferably, the installation groove 111 is a circular groove, the first base 2 is adapted to the installation groove 111, and the first base 2 is cylindrical.

[0061] As Figures 1 to 5 As shown, the other end of the first base 2 is provided with a first concave cavity 20, and one end of the second base 3 is provided with a second concave cavity 31. One end of the second base 3 is movably arranged in the first concave cavity 20, and the inner second concave cavity 31 communicates with the first concave cavity 20.

[0062] The switch main body 41 is arranged on the inner peripheral wall of the first concave cavity 20, and the trigger member 42 is arranged on one end of the second base 3 and is used to move under the drive of the second base 3 to abut against or disengage from the switch main body 41 to trigger the switch 4 to generate a loosening signal.

[0063] Specifically, the opening of the second concave cavity 31 faces the first base 2. The trigger member 42 is arranged on the end of the second base 3 with an opening.

[0064] When the switch main body 41 abuts against the trigger member 42, the switch 4 is connected; when the switch main body 41 disengages from the trigger member 42, the switch 4 is disconnected; the switch main body 41 and the trigger member 42 are in physical contact for making and breaking, which can connect or disconnect the switch 4 in time and send a loosening signal in time, avoiding problems such as malfunction and failure caused by the aging of electronic components in the electronic instrument after long-term use.

[0065] In an embodiment of the present invention, the switch main body 41 extends along the inner peripheral wall of the first concave cavity 20, and the trigger member 42 abuts against or disengages from the end of the switch main body 41.

[0066] Specifically, one end of the second base 3 is movably arranged within the first base 2, and the trigger 42 moves along with the second base 3, abuts or disengages from the end of the switch body 41, triggering the switch 4 and sending out a loosening signal.

[0067] In the above solution, the trigger 42 contacts the end of the switch body 41, and the two are prone to collision, resulting in damage to the trigger 42 and the switch body 41, which is not conducive to the repeated use of the switch 4.

[0068] In another embodiment of the present invention, the switch body 41 extends along the inner peripheral wall of the first cavity 20, and the trigger 42 movably extends into the inner side of the switch body 41, abutting or disengaging from the inner peripheral wall of the switch body 41.

[0069] Specifically, when the trigger 42 movably extends into the inner side of the switch body 41 and contacts the switch body 41, no collision will occur, thus not causing damage to the trigger 42 and the switch body 41, facilitating the repeated use of the switch 4 and helping to reduce costs.

[0070] The inner peripheral wall of the switch body 41 is flush with the inner peripheral wall of the opening of the first cavity 20. At least part of the trigger 42 is arranged outside the opening of the second cavity 31. The inner peripheral wall of the switch body 41, the outer peripheral edge of the trigger 42, and the outer peripheral wall of the second base 3 are flush.

[0071] Specifically, the cross-section of the switch body 41 is arc-shaped, having an inner peripheral wall and an outer peripheral wall. The inner peripheral wall of the switch body 41, the inner peripheral wall of the opening of the first cavity 20, the outer peripheral edge of the trigger 42, and the outer peripheral wall of the second base 3 are flush. The trigger 42 can connect the two switch bodies 41.

[0072] As Figures 8 to 12 shown, the first cavity 20 includes a first groove 21. The first groove 21 is arranged on the outer peripheral edge of one end of the first base 2 and recesses inward. The switch body 41 is snap-fitted in the first groove 21.

[0073] Specifically, the switch body 41 is in interference fit with the first groove 21. During installation, the switch body 41 can be fixed in the first base 2 to prevent the switch body 41 from detaching from the first base 2.

[0074] The end face of the switch body 41 is flush with the end face of the first base 2 at the edge of the notch of the first groove 21, facilitating the abutment of one end of the first base 2 against the bottom wall of the installation groove 111.

[0075] As Figure 5 , Figure 6 , Figure 8 and Figure 9 shown, two first grooves 21 are provided at one end of the first base 2 at intervals, the switch bodies 41 are two, and are respectively arranged in the two first grooves 21. The two switch bodies 41 are electrically connected with leads for forming a loop with the trigger 42.

[0076] Specifically, the first groove 21 is an arc-shaped groove, and the two first grooves 21 are arranged at intervals.

[0077] The switch body 41 is a conductive sheet, and the trigger 42 is a conductor.

[0078] One end of the lead is installed on the wall-mounted device main body 1, and the other end is connected to the conductive sheet. A through hole is provided on the bottom wall of the installation groove 111, and the lead is arranged through the through hole. The lead is long enough and can be pulled a certain distance.

[0079] When the wall-mounted device main body 1 is installed, first pull the lead to increase the length of the lead located in the installation groove 111, and then install the conductive sheet in the first groove 21. The conductive sheet is in interference fit with the first groove 21, so that the conductive sheet can be stably installed in the first base 2 and prevent the conductive sheet from detaching from the first base 2. After the conductive sheet is installed, reduce the length of the lead located in the installation groove 111 until the first base 2 abuts against the bottom wall of the installation groove 111.

[0080] Preferably, the two first grooves 21 are symmetrically arranged along the center line of the first base 2.

[0081] As Figures 8 to 12 shown, the first cavity 20 further includes a second groove 22, the second groove 22 is arranged at the other end of the first base 2 and is recessed inward, and the diameter of the second groove 22 is smaller than the outer diameter of the first base 2.

[0082] The second groove 22 extends inward to the inner circumference of the bottom end of the first groove 21 and communicates with the inner circumferential wall of the first groove 21.

[0083] Preferably, the second groove 22 extends inward and penetrates through the inner circumferential wall of the bottom end of the first groove 21.

[0084] Specifically, the second groove 22 is a circular groove, and the second base 3 is cylindrical. The first groove 21 and the second groove 22 are respectively arranged at two ends of the first base 2, and their extending directions are opposite and extend for a certain length. The inner peripheral wall of the first groove 21 close to the center line of the first base 2 is flush with the inner peripheral wall of the second groove 22. The first groove 21 communicates with the second groove 22 and the first groove 21 extends beyond the bottom wall of the second groove 22.

[0085] The communication length between the second groove 22 and the first groove 21 is the maximum distance at which the wall-mounted device main body 1 and the fixing member 7 can be disengaged, that is, the maximum distance at which the wall-mounted device main body 1 can be disengaged. When the switch main body 41 and the trigger member 42 move away from each other by the maximum distance, the switch 4 disconnects and emits a disengagement signal. The communication length between the second groove 22 and the first groove 21 can be reasonably set according to actual requirements.

[0086] The wall-mounted device further includes a guide ring inner sleeve 6, which is arranged in the second cavity 31. Part of the trigger member 42 is sleeved and fixed between the inner peripheral wall of the second cavity 31 and the guide ring inner sleeve 6, and then turns outward and extends to the outer periphery of the opening of the second cavity 31.

[0087] In the above solution, the guide ring inner sleeve 6, the trigger member 42 and the second base 3 are sleeved in sequence, and the trigger member 42 can be fixed on the second base 3 so that the trigger member 42 moves together with the second base 3.

[0088] Preferably, the trigger member 42 includes a sleeve 421. The second base 3 is sleeved outside the sleeve 421. One end of the sleeve 421 extends outward to form an outward flange 422, which abuts against one end of the second base 3. The peripheral wall of the outward flange 422 abuts against the guide piece.

[0089] The outward flange 422 is annular.

[0090] The bottom wall of the second cavity 31 is recessed inward to form a fourth groove 32. The sleeve 421 is arranged in the second cavity 31. One end of the sleeve 421 protrudes from one end of the second base 3 and extends outward to form the outward flange 422. The outward flange 422 is placed on one end of the second base 3. The other end of the sleeve 421 extends inward to form an inward flange 423, which is arranged in the fourth groove 32 and is flush with the bottom wall of the second cavity 31. The other end of the guide ring inner sleeve 6 abuts against the inward flange 423. The guide ring inner sleeve 6 can fix the trigger member 42 in the second base 3 so that the trigger member 42 moves together with the second base 3.

[0091] The wall-mounted device further includes a fixing member 7, one end of which sequentially passes through the bottom wall of the installation groove 111, the first base 2, and the second base 3, for mounting the wall-mounted device main body 1 on a wall.

[0092] In an embodiment of the present invention, the first base 2 is connected to the bottom wall of the installation groove 111, and the other end of the second base 3 is connected to a wall.

[0093] Specifically, when the wall-mounted device main body 1 becomes loose, the first base 2 moves a certain distance along with the wall-mounted device main body 1, the switch main body 41 moves a certain distance and separates from the trigger member 42, and the switch main body 41 disconnects and generates a loosening signal.

[0094] In another embodiment of the present invention, the wall-mounted device further includes an elastic member 5, which is compressibly arranged between the first base 2 and the second base 3, and is used to move the first base 2 and the second base 3 away from each other when the wall-mounted device main body 1 becomes loose;

[0095] Preferably, the bottom wall of the first cavity 20 is recessed inward to form a third groove 23, one end of the elastic member 5 abuts against the bottom wall of the third groove 23, and the other end passes through the inner sleeve of the guide ring 6 and abuts against the bottom wall of the second cavity 31.

[0096] In the above solution, the elastic member 5 is compressibly arranged between the first base 2 and the second base 3. When the wall-mounted device main body 1 becomes loose, the elastic member 5 resets, and both ends of the elastic member 5 can push to facilitate the movement of the first base 2 and the second base 3 away from each other.

[0097] Specifically, the elastic member 5 is installed between the first base 2 and the second base 3. One end of the expansion bolt sequentially passes through the bottom wall of the installation groove 111, the first base 2, the elastic member 5, and the second base 3 and is connected to a wall. A bolt is provided at the other end of the expansion bolt, and the bolt abuts against the installation portion 11, which is arranged at one end of the installation portion 11 away from the wall. Connecting the installation portion 11 and the wall with the expansion bolt can mount the wall-mounted device main body 1 on the wall. At this time, one end of the first base 2 abuts against the bottom wall of the installation groove 111, the other end of the second base 3 abuts against the wall, and the elastic member 5 is in a compressed state.

[0098] When the wall-mounted device main body 1 becomes loose, the elastic member 5 resets, both ends of the elastic member 5 respectively abut against the first base 2 and the second base 3, causing the first base 2 and the second base 3 to move away from each other, and the switch main body 41 and the trigger member 42 move away from each other by a certain distance, and the switch 4 disconnects.

[0099] Preferably, the first base 2, the elastic member 5, the second base 3, and the fixing member 7 are coaxially arranged.

[0100] The first base 2, the elastic member 5, and the second base 3 are sleeved on the fixing member 7. While fixing the main body 1 of the wall-mounted device, the fixing member 7 can clamp the first base 2, the elastic member 5, and the second base 3 between the bottom wall of the installation groove 111 and the wall, which is convenient for installation and more flexible to use.

[0101] The elastic member 5 is a spring.

[0102] In the present invention, the fixing member 7 may not be arranged at the installation groove 111, and the fixing member 7 is arranged on the installation portion 11 outside the installation groove 111. The first base 2, the elastic member 5, and the second base 3 are not sleeved on the fixing member 7.

[0103] Specifically, the elastic member 5 is arranged in the third groove 23 and the second cavity 31, and the trigger member 42 is sleeved on the outer periphery of the elastic member 5, which can reduce the overall size of the first base 2, the elastic member 5, and the second base 3, facilitate reducing the installation space, and is convenient for use.
