Description

Technical Field

[0001] This invention belongs to the field of clothing processing, and more specifically, relates to a clothing processing device. Background Technology

[0002] In existing technologies, clothing processing equipment with multiple processing modules, such as washer-dryer combos and twin-tub washing machines, faces the issue of drainage between the upper and lower modules. Generally, the upper module, being higher, drains downwards using gravity, while the lower module, being lower, typically uses a drain pump for upward drainage. A T-junction is installed between the two modules, with two ports connecting to the drain outlets of the two modules and the other port connecting to an external drain pipe to discharge water outside the equipment. However, a problem exists where drainage from the upper module can easily enter the lower module through the T-junction, contaminating it.

[0003] Chinese Patent Application No. CN201910257772.6 discloses a clothing processing device, comprising: a first clothing processing module; a second clothing processing module; and a drainage system. The drainage system includes a drainage pump, a first drainage pipe, and a second drainage pipe. The drainage pump is connected between the drain outlet of the first clothing processing module and a first end of the first drainage pipe. The first end of the second drainage pipe is connected to the drain outlet of the second clothing processing module. The second end of the first drainage pipe is connected to the second drainage pipe, and the connection point between the second end of the first drainage pipe and the second drainage pipe is lower than at least a portion of the first drainage pipe. According to the clothing processing device of this embodiment, setting the connection point between the second end of the first drainage pipe and the second drainage pipe lower than at least a portion of the first drainage pipe allows the weight of the water in the second drainage pipe to counteract the pressure of the drainage pump, preventing water discharged from the first drainage pipe from being forced into the second clothing processing module and ensuring the normal operation of the clothing processing device.

[0004] However, the patent requires the T-junction to be positioned 50-300mm below the highest point of the first drain pipe. If space constraints within the garment processing device necessitate placing the T-junction close to the highest point of the first drain pipe, and if the T-junction is positioned 0-50mm below the highest point, the problem of water flowing into the lower garment processing module when the upper module drains alone cannot be resolved. Furthermore, when both garment processing modules drain simultaneously, water from the lower module may be pumped into the upper module, or the upper module may drain slowly, causing waterway interference that affects the drainage of the garment processing equipment.

[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. The purpose is to provide a garment processing device. A partition plate is set in the three-way pipe of the garment processing device, which can guide the drainage of two water paths separately and avoid mutual interference between the water paths. Furthermore, the partition plate forms a negative pressure at the outlet of the section of the three-way pipe connected to the upper drainage pipe to draw water from the upper water pipe, thereby improving the drainage smoothness of the upper drainage pipe. The vertical setting position of the three-way pipe is not limited.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a garment processing device, including...

[0008] First garment processing unit;

[0009] The second garment processing unit is located above the first garment processing unit;

[0010] A drain pump is connected to the drain outlet of the first clothing processing unit;

[0011] The first drain pipe has an inlet end connected to the drain pump and an outlet end extending upwards.

[0012] The second drain pipe has its inlet end connected to the drain outlet of the second clothing processing unit, and its outlet end extending downwards.

[0013] A three-way pipe includes a first pipe section, a second pipe section, and a third pipe section that are connected. The inlet of the first pipe section is connected to the outlet of the first drain pipe, the inlet of the second pipe section is connected to the outlet of the second drain pipe, and the third pipe section is connected to an external drain pipe for downward drainage.

[0014] The three-way pipe has a partition plate inside, which is separated between the outlets of the first pipe section and the second pipe section. It is used to guide the water from the first drain pipe and the second drain pipe into the third pipe section respectively, and to form a negative pressure at the outlet of the second pipe section to draw water from the second drain pipe when the first drain pipe is draining.

[0015] Furthermore, the partition plate extends between the first pipe segment and the second pipe segment, and extends into the third pipe segment, forming a first chamber and a second chamber in the tee pipe that are respectively connected to the outlets of the first pipe segment and the second pipe segment. Both the first chamber and the second chamber are connected to the outlet of the third pipe segment.

[0016] The inner diameter of the first chamber is smaller than the inner diameters of the first pipe section and the third pipe section. The second chamber forms a negative pressure to draw water from the second drain pipe when the first drain pipe drains water.

[0017] Furthermore, the first pipe segment extends laterally, the third pipe segment extends downward at an angle from the outlet end of the first pipe segment, and the second pipe segment extends upward at an angle from the second pipe segment.

[0018] The partition plate is connected to the inner wall of the tee pipe, and extends obliquely from the first pipe section into the third pipe section, extending downward beyond the connection port of the second pipe section on the third pipe section.

[0019] Furthermore, the second pipe segment is located on the upper side of the peripheral wall of the third pipe segment and extends upward at an angle away from the first pipe segment; the connection port of the second pipe segment on the third pipe segment is at a certain distance from the top wall of the first pipe segment.

[0020] Furthermore, the first drain pipe extends upward from the drain pump to the space between the second clothing processing unit and the first clothing processing unit, and then extends horizontally. The first pipe segment extends horizontally from the outlet end of the first drain pipe, and the angle between the third pipe segment and the first pipe segment is an obtuse angle.

[0021] Furthermore, the tee also includes a check valve, which is disposed in the inlet of the second pipe section.

[0022] Furthermore, the drain outlet of the second garment processing unit is located above the first pipe section, and the second drain pipe extends upward from the second pipe section in a direction away from the drain outlet of the second garment processing unit, and then bends and extends towards the drain outlet of the second garment processing unit.

[0023] Preferably, the bending angle of the second drain pipe is an acute angle.

[0024] Furthermore, the tee pipe is set at the same or nearly the same horizontal level as the highest section of the first drain pipe;

[0025] Preferably, the vertical distance between the connection point of the first pipe segment and the third pipe segment and the axis of the highest segment of the first drain pipe is less than 50mm.

[0026] Furthermore, the first garment processing unit is a garment washing unit, the second garment processing unit is a garment drying unit, the inner diameter of the first pipe section and the inner diameter of the third pipe section are the same, and the inner diameter of the second pipe section is smaller than the inner diameter of the first pipe section.

[0027] Furthermore, it also includes a housing, wherein the three-way pipe is fixed to the side wall of the housing between the first clothing processing unit and the second clothing processing unit;

[0028] The first pipe section is provided with a connecting plate, which is fixed to the reinforcing beam of the box body by a connector.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0030] (1) The T-connector of the garment processing equipment of the present invention has an internal partition plate, and two drainage routes are planned within the T-connector. When the first and second drain pipes drain, the water flows to the outlet of the third pipe section on both sides of the partition plate, avoiding mutual interference between the first and second drain pipes and backflow into the other drain pipe. Furthermore, because the partition plate creates a negative pressure at the outlet of the second pipe section when the first drain pipe drains, it draws water from the second drain pipe, causing the water in the second drain pipe to be drawn into the T-connector and discharged due to the negative pressure, thus maintaining smooth drainage of the second drain pipe. As a result, the drainage pipeline is unobstructed, and the vertical placement of the T-connector in the garment processing equipment is not limited, allowing for a more reasonable placement of the T-connector and improving the space utilization of the equipment.

[0031] (2) The present invention sets the first pipe section of the tee pipe horizontally, the third pipe section is axially connected to the first pipe section and extends downward at an inclination, and the second pipe section extends upward at an inclination from the third pipe section. The outlet of the second pipe section is lower than the connection between the first pipe section and the third pipe section. When the second drain pipe drains into the second pipe section, the drainage will flow downward and avoid flowing to the outlet of the first pipe section above. This can prevent the drainage in the second drain pipe from flowing into the first drain pipe. Combined with the setting of the partition plate, the drainage of the tee pipe is greatly guaranteed.

[0032] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0041] 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.

[0042] like Figures 1 to 3 As shown, the present invention provides a double garment processing device, which includes a first garment processing unit 1, a second garment processing unit 2, a drain pump, a first drain pipe 11, a second drain pipe 21, and a three-way pipe 3.

[0043] The second garment processing unit 2 is located above the first garment processing unit 1. The first garment processing unit 1 and the second garment processing unit 2 can be used to wash and / or dry garments. The drain pump is connected to the drain outlet of the first garment processing unit 1. The inlet end of the first drain pipe 11 is connected to the drain pump, and the outlet end of the first drain pipe 11 extends upwards. The inlet end of the second drain pipe 21 is connected to the drain outlet of the second garment processing unit 2, and the outlet end extends downwards.

[0044] This invention utilizes a three-way pipe 3 to connect the upper second clothing processing unit 2 and the lower first clothing processing unit 1, allowing them to share a single external drain pipe 43 for drainage. The three-way pipe 3 comprises three interconnected sections: a first pipe section 31, a second pipe section 32, and a third pipe section 33. The inlet of the first pipe section 31 is connected to the outlet of the first drain pipe 11; the inlet of the second pipe section 32 is connected to the outlet of the second drain pipe 21; and the third pipe section 33 is connected to the external drain pipe 43 for downward drainage.

[0045] The three-way pipe 3 has a partition plate 34, which is separated between the outlets of the first pipe section 31 and the second pipe section 32. The partition plate 34 is used to guide the water from the first drain pipe 11 and the second drain pipe 21 into the third pipe section 33, and to create a negative pressure at the outlet of the second pipe section 32 to draw water from the second drain pipe 21 when the first drain pipe 11 is draining.

[0046] The T-connector 3 of the garment processing equipment of the present invention has an internal partition plate 34, and two drainage routes are planned within the T-connector 3. When the first drain pipe 11 and the second drain pipe 21 drain, the water flows to the outlet of the third pipe section 33 on both sides of the partition plate 34, preventing the water from flowing back into each other's drain pipes due to mutual interference. Furthermore, because the partition plate 34 creates a negative pressure at the outlet of the second pipe section 32 when the first drain pipe 11 drains, it draws water from the second drain pipe 21, causing the water in the second drain pipe 21 to be drawn into the T-connector and discharged, maintaining unobstructed drainage of the second drain pipe 21. Therefore, the drainage pipeline is unobstructed, and the vertical placement of the T-connector 3 in the garment processing equipment is not limited, allowing for a more rational placement of the T-connector 3 and improving the space utilization of the equipment.

[0047] Because a partition plate 34 is installed inside the tee pipe 3, even if the angle between the water inlet directions of the first drain pipe 11 and the second drain pipe 21 is not restricted, even if the angle is 180 degrees, they will not interfere with each other and the water path will remain unobstructed.

[0048] Furthermore, the partition plate 34 extends between the first pipe section 31 and the second pipe section 32, extending into the third pipe section 33. A first chamber and a second chamber are formed within the tee pipe 3. The two ends of the first chamber are connected to the outlets of the first pipe section 31 and the third pipe section 33, respectively, and the two ends of the second chamber are connected to the outlets of the second pipe section 32 and the third pipe section 33, respectively.

[0049] The inner diameter of the first chamber is smaller than the inner diameters of the first pipe section 31 and the third pipe section 33. The second chamber forms a negative pressure to draw water from the second drain pipe 21 when the first drain pipe 11 drains water.

[0050] During the drainage process of the first drain pipe 11, water flows from the inlet of the first pipe section 31 into the first chamber. The inner diameter of the tee pipe 3 decreases, and the water is sprayed at high speed to the outlet end of the third pipe section 33, whose inner diameter suddenly increases. During the above process, a certain negative pressure will be generated in the second chamber, so that the water in the second drain pipe 21 is sucked into the tee due to the negative pressure, thus keeping the drainage of the second drain pipe 21 unobstructed.

[0051] Preferably, the first pipe segment 31 extends laterally, the third pipe segment 33 extends downward at an angle from the outlet end of the first pipe segment 31, and the second pipe segment 32 extends upward at an angle from the second pipe segment 32.

[0052] The partition plate 34 is connected to the inner wall of the tee pipe 3, and extends obliquely from the first pipe section 31 into the third pipe section 33, extending downward beyond the connection port of the second pipe section 32 on the third pipe section 33.

[0053] This invention arranges the first segment 31 of the three-way pipe 3 laterally, the third segment 33 axially intersects the first segment 31 and extends downward at an inclination, and the second segment 32 extends upward at an inclination from the third segment 33. The outlet of the second segment 32 is lower than the connection between the first segment 31 and the third segment 33. When the second drain pipe 21 drains water into the second segment 32, the water will flow downward and avoid flowing upward to the outlet of the first segment 31. This can prevent the water in the second drain pipe 21 from flowing into the first drain pipe 11. Combined with the setting of the partition plate 34, the smooth drainage of the three-way pipe 3 is greatly ensured.

[0054] The second pipe segment 32 is disposed on the upper side of the peripheral wall of the third pipe segment 33, and extends upward at an angle away from the first pipe segment 31. The communication port of the second pipe segment 32 on the peripheral wall of the third pipe segment 33 is at a certain distance from the top wall of the first pipe segment 31.

[0055] Furthermore, the three-way pipe 3 also includes a check valve 35, which is installed in the inlet of the second pipe section 32 to prevent water in the three-way pipe 3 from flowing back into the first drain pipe 11.

[0056] Since the first garment processing unit 1 at the bottom uses a drain pump to drain water, if the external drain pipe 43 at the bottom is blocked, the drain pump will not stop, causing water to flow up along the external drain pipe 43 and be forced into the second garment processing unit 2, resulting in machine malfunction.

[0057] The present invention provides a check valve 35 in the inlet of the second pipe section 32 of the tee pipe 3. The drainage of the second clothing processing unit 2 can enter the tee through the check valve 35. When the external drain pipe at the lower end is blocked, the water in the external drain pipe 43 will not flow back through the second pipe section 32 into the second clothing processing unit 2, thus avoiding contamination of the second clothing processing unit 2 and preventing equipment damage.

[0058] Furthermore, the drain outlet of the second garment processing unit 2 is located above the first pipe section 31, and the second drain pipe 21 extends upward from the second pipe section 32 in a direction away from the drain outlet of the second garment processing unit 2, and then bends and extends towards the drain outlet of the second garment processing unit 2.

[0059] Preferably, the second drain pipe 21 extends upward along the inclined direction of the second pipe section 32 in a direction away from the drain outlet of the second clothing processing unit 2, and then bends and extends towards the drain outlet of the second clothing processing unit 2.

[0060] There are one or more curved sections in the second drain pipe 21 between the second pipe section 32 and the upper drain outlet.

[0061] Because the second drain pipe 21 has a curved section, it resists the upward flow of the lower drainage and increases the resistance of the water flowing upward against the current. This balances the drainage pressure with that of the first drain pipe 11, preventing water from being pumped into the second drain pipe 21 through the second pipe section 32 when the first drain pipe 11 is draining. This ensures smooth drainage and avoids mutual interference between the drainage paths.

[0062] Preferably, the bending angle of the second drain pipe 21 is an acute angle.

[0063] Furthermore, the tee pipe 3 is set at the same or nearly the same horizontal height as the highest section of the first drain pipe 11.

[0064] The highest section of the three-way pipe 3 and the first drain pipe 11 of the present invention are set at the same horizontal level or close to the same horizontal level, which allows for more flexible setting of the position of the three-way pipe 3. The three-way pipe 3 can be set at the crossbeam between the first clothing processing unit 1 and the second clothing processing unit 2. By utilizing the width of the crossbeam, the space inside the clothing processing equipment can be used more rationally.

[0065] The height of the connection between the first pipe segment 31 and the third pipe segment 33 can be lower or higher than the highest point of the first drain pipe 11. Preferably, the height of the connection between the first pipe segment 31 and the third pipe segment 33 is within 50mm lower or higher than the highest point of the first drain pipe 11.

[0066] Preferably, the vertical distance between the connection point of the first pipe segment 31 and the third pipe segment 33 and the axis of the highest segment of the first drain pipe 11 is less than 50mm. The outlet pipe of the first drain pipe 11 is the highest segment.

[0067] This allows the outlet end of the three-way pipe 3 and the first drain pipe 11 to be set approximately horizontally, and the three-way pipe 3 can be set between the first clothing processing unit 1 and the second clothing processing unit 2, which facilitates the installation of the three-way pipe 3 and makes reasonable use of the space inside the clothing processing equipment.

[0068] In a preferred embodiment, the first drain pipe 11 extends upward from the drain pump to between the second clothing processing unit 2 and the first clothing processing unit 1, and then extends horizontally. The highest segment of the first pipe 31 extends horizontally from the outlet end of the first drain pipe 11, and the angle between the third pipe 33 and the first pipe 31 is an obtuse angle.

[0069] like Figure 1 As shown, the garment processing equipment also includes a housing 4, with the first garment processing unit 1 and the second garment processing unit 2 respectively located at the lower and upper parts of the housing 4. The three-way pipe 3 is fixed to the side wall of the housing 4 between the first garment processing unit 1 and the second garment processing unit 2.

[0070] The housing 4 includes a connected housing plate 42 and a reinforcing beam 41, the reinforcing beam 41 being disposed between the first clothing processing unit 1 and the second clothing processing unit 2.

[0071] The tee pipe 3 also includes a connecting plate 36, which is connected to the outer wall of the first pipe section 31 and extends outward beyond the first pipe section 31. The connecting plate 36 is fixed to the reinforcing beam 41 of the housing 4 by a connector.

[0072] Preferably, the connecting plate 36 is fixed on the reinforcing beam 41, the first pipe section 31 is located in the space below the reinforcing beam 41, the third pipe section 33 is inclined downward, and the outlet end of the first drain pipe 11 extends into the space below the reinforcing beam 41, so as to make full use of the space in the thickness direction of the reinforcing beam 41.

[0073] Specifically, the connecting plate 36, the first pipe section 31, and the third pipe section 33 are provided with reinforcing ribs to improve the structural strength of the tee pipe 3. The connecting plate 36 is provided with mounting holes and is fixed to the reinforcing beam 41 by bolts or screws.

[0074] The first garment processing unit 1 and the second garment processing unit 2 can be used to wash or dry garments. The duplex garment processing equipment can be a duplex washing machine, a washer-dryer combo, or a duplex dryer.

[0075] Preferably, the first garment processing unit 1 is a garment washing unit, and the second garment processing unit 2 is a garment drying unit. The first drain pipe 11 is used to discharge washing water, and the second drain pipe 21 is used to discharge condensate. The inner diameter of the first pipe section 31 and the third pipe section 33 is the same, and the inner diameter of the second pipe section 32 is smaller than the inner diameter of the first pipe section 31.

[0076] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
