A wall-mounted washing machine

Abstract

This invention discloses a wall-mounted washing machine, comprising a drum module including an outer drum, a rear panel at the rear of the outer drum, an exhaust pipe disposed on the rear panel, one end of the exhaust pipe communicating with the outer drum, and an air chamber on the rear panel communicating with the outside of the washing machine and the other end of the exhaust pipe. This invention, by providing an air chamber on the rear panel of the wall-mounted washing machine and connecting the exhaust pipe (communicating with the outer drum) to the air chamber, allows air or humid air from inside the washing machine to enter the air chamber through the exhaust pipe and be discharged to the outer periphery of the rear panel. This results in faster discharge and prevents the accumulation of air or humid air between the mounting wall and the rear panel, thus avoiding corrosion of components on the rear panel and preventing damage to components caused by humid air entering the drum module.

Description

Technical Field

[0001] This invention belongs to the field of washing machines, and more specifically, relates to a wall-mounted washing machine. Background Technology

[0002] In existing technology, the washing drum assembly of a drum washing machine is in a sealed state when it is working. However, if the inside of the washing machine is completely sealed, air pressure will cause the inlet and outlet to fail. Therefore, an overflow hole is provided at the rear of the outer drum, located at the top of the drum. Its main functions are to overflow and drain water and to connect with atmospheric pressure.

[0003] Front-loading washing machines generally have a heating function, and it's common for the water inside the drum to boil. When used, the heated water produces a large amount of hot and humid air, so an exhaust pipe connected to the vent is installed on the washing machine. The exhaust pipe connects the inside of the washing machine to the outside, facilitating water intake and drainage. Additionally, wall-mounted washing machines, during operation, also expel the hot and humid air from inside the machine to the space between the back of the machine and the wall. Because hot and humid air is hot and has a low density, it rises and is expelled to the outside through the opening at the top of the washing machine.

[0004] If hot and humid gases cannot be effectively and promptly expelled, they will accumulate between the back of the washing machine and the wall where it is mounted. This can easily cause corrosion and rust on the electrical components and metal parts at the back, affecting the overall reliability of the machine and potentially causing damage. Hot and humid gases may even enter the washing machine's interior, corroding the internal electrical and metal components, causing them to rust or even malfunction.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a wall-mounted washing machine with an air chamber at the rear of the washing machine. The hot and humid air inside the washing machine enters the air chamber through the exhaust pipe and is discharged to the outside of the washing machine through the air chamber. The hot and humid air will not accumulate and spread between the washing machine and the wall where it is installed, thus avoiding corrosion and damage to the washing machine's parts.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a wall-mounted washing machine, comprising,

[0008] The cylindrical module includes an outer cylinder, and a back plate is provided at the rear of the outer cylinder;

[0009] An exhaust pipe is provided on the rear panel, and one end of the exhaust pipe is connected to the outer cylinder;

[0010] The rear panel has an air chamber that communicates with the outside of the washing machine and is connected to the other end of the exhaust pipe.

[0011] This invention provides an air chamber on the back panel of a wall-mounted washing machine. An exhaust pipe connected to the outer drum is connected to the air chamber. Air or humid air inside the washing machine enters the air chamber through the exhaust pipe and is then discharged to the outer periphery of the back panel. This faster discharge speed prevents air or humid air from accumulating and spreading between the mounting wall and the back panel, thus avoiding corrosion of components on the back panel and preventing humid air from entering the drum module and causing damage to components.

[0012] Furthermore, the air chamber is located near the outer periphery of the rear back plate;

[0013] Preferably, the back panel includes an outer cylinder rear wall and an extension plate extending outward from the edge of the outer cylinder rear wall, and the air chamber is disposed on the extension plate.

[0014] Furthermore, the air chamber includes,

[0015] A recessed cavity is recessed on the rear side of the rear back panel;

[0016] A sealing element is disposed on the opening of the cavity to seal the opening of the cavity;

[0017] Alternatively, the air chamber includes,

[0018] A recessed cavity is recessed on the rear side of the back panel, and a mounting groove is provided on the outer periphery of the cavity opening;

[0019] A sealing ring is installed in the mounting groove of the recessed cavity to be pressed between the mounting wall and the recessed cavity to form the air chamber.

[0020] Furthermore, an exhaust port is provided on the outer peripheral wall of the rear back plate, which communicates with the air chamber.

[0021] Preferably, one end of the air chamber is connected to the exhaust pipe, and the other end is connected to the exhaust port.

[0022] Furthermore, the exhaust port is located on the outer peripheral sidewall of the rear panel.

[0023] Furthermore, it also includes a decorative frame fitted onto the outer periphery of the rear panel, with the exhaust port penetrating through the outer periphery of the decorative frame.

[0024] Furthermore, the exhaust port is provided with exhaust fan blades, which are inclined downwards from the inside of the exhaust port toward the outside.

[0025] Furthermore, the air chamber includes,

[0026] The first chamber extends from the other end of the exhaust pipe toward the outer peripheral sidewall of the rear panel;

[0027] The second chamber extends downward from the first chamber;

[0028] The exhaust port is located on the outside of the second chamber and communicates with the second chamber.

[0029] Furthermore, one end of the first chamber extends horizontally from the middle portion of the rear back panel to the outer peripheral edge of the rear back panel, and the second chamber extends vertically downward from the other end of the first chamber, with the exhaust port located in the middle portion of the second chamber.

[0030] Furthermore, it also includes,

[0031] An overflow pipe is connected to the vent hole at the top of the outer cylinder and extends downwards.

[0032] The exhaust pipe includes,

[0033] The first exhaust pipe section is connected at one end to the overflow pipe and at the other end extends upward from bottom to top, higher than the exhaust hole;

[0034] The second exhaust pipe section extends from the other end of the first exhaust pipe section along the left-right direction toward the side wall of the washing machine and communicates with one end of the air chamber.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0036] This invention provides an air chamber on the back panel of a wall-mounted washing machine. An exhaust pipe connected to the outer drum is connected to the air chamber. Air or humid air inside the washing machine enters the air chamber through the exhaust pipe and is then discharged to the outer periphery of the back panel. This faster discharge speed prevents air or humid air from accumulating and spreading between the mounting wall and the back panel, thus avoiding corrosion of components on the back panel and preventing humid air from entering the drum module and causing damage to components.

Therefore, they should not be construed as limiting this invention.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] like Figures 1 to 4 As shown, the wall-mounted washing machine of the present invention includes: a drum module 1, an exhaust pipe 3, and an air chamber 2. The drum module 1 includes an outer drum 11, and a back panel 4 is provided at the rear of the outer drum 11. The exhaust pipe 3 is disposed on the back panel 4, and one end of the exhaust pipe 3 is connected to the outer drum 11. The back panel 4 is provided with an air chamber 2 that communicates with the outside of the washing machine and is connected to the other end of the exhaust pipe 3.

[0049] This invention provides an air chamber 2 on the back panel 4 of a wall-mounted washing machine. An exhaust pipe 3, which is connected to the outer drum 11, is connected to the air chamber 2. Air or humid air inside the washing machine enters the air chamber 2 through the exhaust pipe 3 and is discharged to the outer periphery of the back panel 4 through the air chamber 2. The discharge speed is faster, and it can also prevent air or humid air from accumulating and spreading between the mounting wall and the back panel of the washing machine. This can prevent the components on the back panel of the washing machine from being corroded and prevent humid air from entering the washing machine drum module and causing damage to the components.

[0050] The cylinder module 1 also includes an inner cylinder (not shown in the figure), which is located inside the outer cylinder 11 and is coaxially arranged with the outer cylinder 11.

[0051] Furthermore, the air chamber 2 is located near the outer periphery of the rear back plate 4.

[0052] Preferably, the back panel 4 is used to fix the wall-mounted washing machine to the mounting wall 8. The back panel 4 includes the rear wall of the outer drum 11 and an extension plate 41 extending outward from the edge of the rear wall of the outer drum 11, and the air chamber 2 is disposed on the extension plate 41.

[0053] The back panel 4 and the outer cylinder 11 are integrally formed. The extension plate 41 extends radially outward from the outer periphery of the rear wall of the outer cylinder 11. The air chamber 2 is located at the upper end of the back panel 4. The air chamber 2 is connected to the upper end of the exhaust pipe 3.

[0054] The present invention sets the air chamber 2 in the upper part of the back panel 4. The hot and humid air will be discharged into the air chamber 2 through the exhaust pipe 3. Since the hot and humid air has a high temperature and a relatively low density, it will flow upward and be easily discharged into the air chamber 2.

[0055] like Figures 2 to 3 As one embodiment, the air chamber 2 includes a recessed cavity 23, which is recessed on the rear side of the back plate 4.

[0056] The washing machine also includes a sealing ring 24. An installation groove 25 is provided on the outer periphery of the opening of the recess 23. The sealing ring 24 is installed in the installation groove 25 of the recess 23, and is used to press against the mounting wall 8 and the recess 23 to form the air chamber 2.

[0057] In this embodiment, the sealing ring 24 is installed in the mounting groove 25 on the outer periphery of the opening of the recess 23, so that the recess 23 and the mounting wall 8 form a sealed air chamber 2. On the one hand, hot and humid air can be accelerated to be discharged to the outside of the washing machine through the air chamber 2. On the other hand, air will not enter the space between the rear of the washing machine and the mounting wall 8 outside the air chamber 2, thus avoiding large-area damage to the wall and corrosion of the washing machine parts.

[0058] Alternatively, the washing machine may further include a seal. The seal is disposed on the opening of the recess 23 to seal the opening of the recess 23. The seal and the recess 23 form the air chamber 2. The seal is detachably installed in the opening of the recess 23.

[0059] In this embodiment, the sealing element is disposed on the opening of the recess 23, sealing the opening of the recess 23 and forming a sealed air chamber 2 with the recess 23. On the one hand, hot and humid air can be accelerated to be discharged to the outside of the washing machine through the air chamber 2. On the other hand, hot and humid air will not pass through the wall or other spaces behind the washing machine, avoiding damage to the wall and corrosion of the washing machine parts. The sealing element can play a role in partially absorbing the vibration of the washing machine.

[0060] Preferably, the sealing element is a sealing strip or sealing plate, such as an elastic sealing strip, which blocks the opening of the cavity 23 and can also be located between the wall-mounted washing machine and the mounting wall 8 to play a role in vibration reduction.

[0061] In another embodiment, the air chamber 2 is a chamber located on the outer side of the rear back plate 4. Preferably, it is inverted L-shaped. The air chamber 2 is integrally formed with the rear back plate 4. Preferably, the rear back plate 4 is provided with reinforcing ribs 42, and the air chamber 2 is flush with the height of the reinforcing ribs 42 on the rear back plate 4.

[0062] Furthermore, an exhaust port 6 is provided on the outer peripheral wall of the rear back plate 4, which communicates with the air chamber 2. Preferably, one end of the air chamber 2 is connected to the exhaust pipe 3, and the other end is connected to the exhaust port 6.

[0063] The hot and humid air in the air chamber 2 can be discharged to the outside of the washing machine through the exhaust port 6, preventing the hot and humid air from accumulating between the back of the washing machine and the wall.

[0064] A preferred embodiment is that the other end of the exhaust pipe 3 is connected to one end face of the air chamber 2. One end face of the air chamber 2 is provided with a insertion hole, and the other end of the exhaust pipe 3 is inserted into the insertion hole on one end face of the air chamber 2 along its extension direction via an interference fit or sealing. This ensures that hot and humid gas can smoothly enter the air chamber 2 from the exhaust pipe 3.

[0065] The exhaust port 6 is connected to the inner wall of the concave cavity 23 of the air chamber 2.

[0066] In a preferred embodiment, the exhaust port 6 is located on the outer peripheral sidewall of the rear panel 4.

[0067] Since wall-mounted washing machines may be installed in damp spaces such as bathrooms or where water may splash, by placing the exhaust port 6 on the outer peripheral wall at the rear of the washing machine, it is possible to prevent water dripping from above the washing machine from entering the washing machine through the exhaust port 6, thus avoiding the problem of a large amount of water accumulating in the exhaust channel.

[0068] Furthermore, the wall-mounted washing machine also includes a decorative frame 5, which is fitted onto the outer periphery of the back panel 4. The exhaust port 6 penetrates the outer periphery of the decorative frame 5 and exhausts air to the outside of the wall-mounted washing machine through the exhaust port 6 on the decorative frame 5.

[0069] The air chamber 2 is provided with a connecting port 44, which communicates with the outer peripheral wall of the back panel 4 and the outer peripheral wall of the decorative frame 5. Preferably, the connecting port 44 communicates with the outer peripheral side wall of the back panel 4 and the outer peripheral side wall of the decorative frame 5.

[0070] The air chamber 2 can also be disposed on the inner peripheral wall of the decorative frame 5. The air chamber 2 is integrally formed with the decorative frame 5.

[0071] The exhaust port 6 is equipped with an exhaust fan blade 61, which is inclined downward from the inside of the exhaust port 6 to the outside, so as to prevent water splashed from the outside of the washing machine from entering the washing machine through the exhaust port 6.

[0072] The exhaust fan blade 61 is disposed on the exhaust port 6 of the rear panel 4 or on the exhaust port 6 of the decorative frame 5.

[0073] Preferably, a plurality of exhaust fan blades 61 are provided at intervals along the vertical direction inside the exhaust port 6. The exhaust fan blades 61 are rectangular in shape.

[0074] Furthermore, the air chamber 2 includes a first chamber 21 and a second chamber 22 arranged sequentially.

[0075] The first chamber 21 extends from the other end of the exhaust pipe 3 toward the outer peripheral sidewall of the rear back plate 4. The second chamber 22 extends downward from the first chamber 21. The exhaust port 6 is located outside the second chamber 22 and communicates with the second chamber 22.

[0076] In a preferred embodiment, the air chamber 2 is located at the upper left or upper right end of the rear back panel 4. More preferably, the air chamber 2 is located at the upper right end of the rear back panel 4.

[0077] The exhaust port 6 can be located at the upper end, middle part, or lower end of the second chamber 22. Preferably, the exhaust port 6 is located in the middle part of the second chamber 22. When there is a small amount of condensate in the exhaust pipe 3, it can drip onto the lower end of the second chamber 22. Since the amount of condensate is very small, it can be discharged from the exhaust port 6 through evaporation.

[0078] In one specific implementation, one end of the first chamber 21 extends horizontally from the middle part of the upper end of the rear back plate 4 to the outer peripheral edge of the rear back plate 4, and the second chamber 22 extends vertically downward from the other end of the first chamber 21, with the exhaust port 6 located in the middle part of the second chamber 22.

[0079] like Figure 3 As shown, the upper end of the back panel 4 is provided with a mounting part 411 for fixing the wall-mounted washing machine to the mounting wall 8. Preferably, the mounting part 411 is disposed on the extension plate 41. The air chamber 2 is located outside the mounting part 411, between the mounting part 411 on the upper part of the extension plate 41 and the edge of the extension plate 41. The exhaust pipe 3 and the air chamber 2 are disposed on the outer side of the back panel 4, between the wall-mounted washing machine and the mounting wall 8.

[0080] Furthermore, the wall-mounted washing machine also includes an overflow pipe 7. The overflow pipe 7 is connected to the vent 43 on the upper rear side of the outer drum 11 and extends downwards. Preferably, the lower part of the back panel 4 is provided with a drain tee 72, which is connected to the lower end of the overflow pipe 7, for discharging water to the outside of the wall-mounted washing machine.

[0081] The exhaust pipe 3 includes a first exhaust pipe section 31 and a second exhaust pipe section 32 that are connected to each other.

[0082] One end of the first exhaust pipe section 31 is connected to the overflow pipe 7, and the other end extends from bottom to top, higher than the exhaust hole 43.

[0083] The middle part of the overflow pipe 7 is provided with a three-way pipe 71, in which two pipe ports are respectively connected to the upper section and the lower end of the overflow pipe 7, and the other pipe port is connected to the first exhaust pipe section 31.

[0084] The upper section of the overflow pipe 7 extends upward from the opening of the three-way pipe 71 along the outer periphery of the outer cylinder 11, and then extends upward into the vent hole 43.

[0085] The first exhaust pipe section 31 is located on the outer periphery of the upper end of the overflow pipe 7. The first exhaust pipe section 31 has a bent section, which is located at one end of the first exhaust pipe section 31 that connects to the overflow pipe 7. The bent section is an arc-shaped protrusion that bulges outward along the radial direction of the outer cylinder 11. The first exhaust pipe section 31 then extends upward from the bent section along the outer periphery of the outer cylinder 11, and then extends upward in the vertical direction.

[0086] The second exhaust pipe section 32 extends from the other end of the first exhaust pipe section 31 toward one end of the air chamber 2.

[0087] The second exhaust pipe section 32 extends from the other end of the first exhaust pipe section 31 in the left-right direction toward the side wall of the washing machine and communicates with one end of the air chamber 2.

[0088] Both the overflow pipe 7 and the exhaust pipe 3 are flexible hoses, preferably made of EPDM rubber hoses and PVC pipes.

[0089] The back panel 4 is provided with a reinforcing rib 42, and the reinforcing rib 42 is provided with a pipe guiding and fixing structure. The reinforcing rib 42 extends along the circumferential and radial directions of the outer cylinder 11. The reinforcing rib 42 is provided with a slot 45 that matches the overflow pipe 7 and the exhaust pipe 3. The overflow pipe 7 and the exhaust pipe 3 are respectively fixed to the back panel 4 of the wall-mounted washing machine through the slot 45.

[0090] The present invention provides a pipeline guiding and fixing structure on the reinforcing rib 42, which can be adjusted according to the actual position, making it convenient for processing and installation, saving costs, and eliminating the need to process the pipeline into an irregular shape, but only into a straight pipe.

[0091] Preferably, the wall-mounted washing machine has a heating module, and the water vapor generated by the heating module can be discharged to the outside of the wall-mounted washing machine through the exhaust pipe 3, the air chamber 2 and the exhaust port 6.
