Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a garment processing device. Background Technology

[0002] Clothes dryers mainly have two operating modes: internal circulation and external circulation. In internal circulation mode, the drying airflow only circulates inside the dryer, and is less affected by external temperature and humidity, making it suitable for use during rainy seasons. However, the disadvantage is that water vapor is difficult to expel, resulting in a longer drying time. In external circulation mode, the drying airflow exchanges with the outside environment, resulting in a shorter drying time, but it is more affected by external temperature and humidity, making it suitable for dry weather.

[0003] To adapt to drying needs under different weather conditions, dryers need to be equipped with airflow exchange valves to switch between the two operating modes mentioned above. However, most existing airflow exchange valves are separate units, making it difficult to create a linkage between the inlet and outlet valves. This results in low switching efficiency between internal and external circulation and can easily cause circulation problems. Summary of the Invention

[0004] In view of the above situation, this application provides a garment processing device to solve the above problems.

[0005] A garment processing device includes a housing, a flow guiding assembly, and a switching valve. The housing has a first flow channel, the flow guiding assembly has a second flow channel, the first flow channel and the second flow channel are connected end-to-end, and the switching valve is disposed between the housing and the flow guiding assembly.

[0016] In some possible implementations, the first air inlet and the first air outlet are offset from each other, and the second air inlet and the second air outlet are opposite each other.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0066] One embodiment of this application provides a garment processing device, including a housing, a flow guiding assembly, and a switching valve. The housing has a first flow channel, and the flow guiding assembly has a second flow channel, with the first and second flow channels connected end-to-end. The switching valve is disposed between the housing and the flow guiding assembly, and includes an air exchange chamber and a sealing assembly. The air exchange chamber includes a first air chamber and a second air chamber. The first air chamber has a first air inlet and a first air outlet that are connected to each other. The first air inlet is connected to the second flow channel, and the first air outlet is connected to the external environment. The second air chamber has a second air inlet and a second air outlet that are connected to each other. The second air inlet is connected to the external environment, and the second air outlet is connected to the first flow channel. A ventilation hole is provided between the first and second air chambers. The sealing assembly includes a driving member, a first sealing member, and a second sealing member. The driving member is pulsatorically connected to the first sealing member to drive the first sealing member to rotate. The second sealing member is hinged to the first sealing member. The first sealing member is used to movably cover the first air outlet and the ventilation hole, and the second sealing member is used to movably cover the second air outlet. The garment processing equipment has a first circulation state and a second circulation state. The first circulation state includes: a first seal closes the first air outlet but does not close the ventilation hole, and a second seal closes the second air inlet. The second circulation state includes: the first seal does not close the first air outlet but closes the ventilation hole, and the second seal does not close the second air outlet.

[0067] In the above embodiments, in the first circulation state, air enters the first air chamber through the first air inlet and the second flow channel, then enters the second air chamber through the ventilation hole, and finally enters the first flow channel from the second air chamber through the second air outlet. That is, the air circulates within the clothing processing equipment. In the second circulation state, air enters the first air chamber through the first air inlet and the second flow channel, and then enters the external environment through the first air outlet. Simultaneously, air from the external environment enters the second air chamber through the second air inlet and enters the first flow channel from the second air chamber through the second air outlet. That is, the air circulates between the clothing processing equipment and the external environment.

[0068] The garment processing equipment provided in this application is configured with a first seal and a second seal linked together, and a driving component is provided to drive the first seal to rotate, thereby realizing the synchronous opening and closing of the first air outlet and the second air inlet. At the same time, it can also realize the sealing and opening and closing of the ventilation holes. The switching valve has a compact overall structure and high opening and closing efficiency, which is conducive to realizing efficient switching between internal and external circulation of the garment processing equipment and reducing air stagnation.

[0069] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0070] Please see Figure 1 and Figure 2 In some embodiments, the garment handling device 100 includes a housing 10, a flow guiding assembly 20, and a switching valve 30. The housing 10 has a first flow channel 11. Specifically, the housing 10 may include a roller (not shown) having the first flow channel 11 inside, and the first flow channel 11 inside the roller can be used to contain damp garments. The flow guiding assembly 20 has a second flow channel 21. The housing 10 and the flow guiding assembly 20 are connected end-to-end such that the first flow channel 11 and the second flow channel 21 are in communication, allowing air to circulate within the first flow channel 11 and the second flow channel 21 (see [link]). Figure 3A The switching valve 30 is disposed between the housing 10 and the flow guide assembly 20 to discharge air from the second flow channel 21 to the external environment and to introduce air from the external environment into the first flow channel 11 (see [reference]). Figure 3B ).

[0071] Please see Figure 4 , Figure 5 and Figure 6 Specifically, the switching valve 30 includes an air exchange chamber 31 and a sealing assembly 32 disposed in the air exchange chamber 31.

[0072] The ventilation chamber 31 includes a first air chamber 311 and a second air chamber 312 connected to the first air chamber 311. A ventilation hole 313 is provided through the first air chamber 311 and the second air chamber 312, and the ventilation hole 313 connects the first air chamber 311 and the second air chamber 312.

[0073] The first air chamber 311 is provided with a first air inlet 311a and a first air outlet 311b. The first air inlet 311a is connected to the second flow channel 21 (see...). Figure 1 or Figure 2 The first air outlet 311b can connect to the external environment. The second air chamber 312 is provided with a second air inlet 312a and a second air outlet 312b. The second air inlet 312a can connect to the external environment, and the second air outlet 312b connects to the first flow channel 11 (see...). Figure 1 or Figure 2 ).

[0074] The first air inlet 311a and the first air outlet 311b are roughly offset. The second air inlet 312a and the second air outlet 312b are roughly corresponding. The first air outlet 311b and the second air inlet 312a are roughly side by side. This arrangement allows the first air outlet 311b and the second air inlet 312a to be located on the same side of the housing 10. During installation, only a ventilation gap needs to be reserved between one side of the housing 10 and the wall (not shown), thus saving space required for installing the clothing processing equipment 100 and reducing installation requirements. Understandably, if the first air outlet 311b and the second air inlet 312a face different sides of the housing 10, ventilation gaps need to be reserved between both sides of the housing 10 and the wall.

[0075] Please see Figure 4 , Figure 5 and Figure 6 The sealing assembly 32 includes a drive member 321, a first seal member 322, and a second seal member 323. The drive member 321 is disposed on the outside of the ventilation chamber 31, and the drive member 321 is throttle-connected to the first seal member 322 to drive the first seal member 322 to rotate. The first seal member 322 is hinged to the second seal member 323 to drive the second seal member 323 to move.

[0076] The first seal 322 is movably disposed over the first air outlet 311b and the ventilation hole 313. That is, the first seal 322 can close the first air outlet 311b and not close the ventilation hole 313 (see below, first cycle state A), or it can not close the first air outlet 311b and close the ventilation hole 313 (see below, second cycle state B). The second seal 323 is movably disposed over the second air inlet 312a. That is, the second seal 323 can close the second air inlet 312a (see below, first cycle state A), or it can not close the second air inlet 312a (see below, second cycle state B).

[0077] Please see Figures 4 to 7 As the driving component 321 drives the first sealing component 322 to rotate, the second sealing component 323 also moves accordingly, thereby enabling the garment processing equipment 100 to switch between the first cycle state A and the second cycle state B.

[0078] Please see Figure 4 and Figure 5 In the first cycle state A, the first seal 322 closes the first air outlet 311b but does not close the ventilation hole 313, and the second seal 323 closes the second air inlet 312a. At this time, the air in the first flow channel 11 or the second flow channel 21 cannot exchange with the outside environment. The air in the second flow channel 21 can only flow into the first air chamber 311 through the first air inlet 311a, then enter the second air chamber 312 through the ventilation hole 313, and then flow into the first flow channel 11 through the second air outlet 312b. That is, the air only circulates internally within the clothing processing equipment 100.

[0079] Please see Figure 6 and Figure 7 In the second cycle state B, the first seal 322 does not seal the first air outlet 311b and seals the ventilation hole 313, while the second seal 323 does not seal the second air inlet 312a. At this time, the air in the first flow channel 11 or the second flow channel 21 can exchange with the external environment. The air in the second flow channel 21 can flow into the first air chamber 311 through the first air inlet 311a, and then into the external environment through the first air outlet 311b. Simultaneously, air from the external environment can flow into the second air chamber 312 through the second air inlet 312a, and then into the first flow channel 11 through the second air outlet 312b. That is, air can exchange between the clothing processing device 100 and the external environment, achieving external circulation.

[0080] Please see Figure 5 and Figure 7In some embodiments, the first seal 322 is generally L-shaped and includes a first sealing plate 322a and a second sealing plate 322b. The first sealing plate 322a is connected to the second sealing plate 322b to form a limiting space 322c. A drive member 321 drives the first sealing plate 322a and the second sealing plate 322b to rotate about their connection point. The first sealing plate 322a is used to movably cover the first air outlet 311b, and the first and second sealing plates 322a and 322b are used to movably cover the ventilation hole 313. The second seal 323 is rotatably connected to the side of the second sealing plate 322b opposite to the first sealing plate 322a. See also... Figure 5 In the first cycle state A, the first sealing plate 322a closes the first air outlet 311b, while the first sealing plate 322a and the second sealing plate 322b do not close the ventilation hole 313. Please refer to [link / reference]. Figure 7 In the second cycle state B, the first sealing plate 322a does not close the first air outlet 311b, and the first sealing plate 322a and the second sealing plate 322b together close the ventilation hole 313.

[0081] Please see Figure 5 and Figure 7 In some embodiments, a limiting plate 314 is provided at the first air outlet 311b of the first air chamber 311. The limiting plate 314 is provided corresponding to the limiting space 322c. In the first cycle state A, the limiting plate 314 abuts against the first sealing plate 322a to prevent the first sealing plate 322a from continuing to rotate. In the second cycle state B, the limiting plate 314 abuts against the second sealing plate 322b to prevent the second sealing plate 322b from continuing to rotate. Thus, the limiting plate 314 can be used to limit the rotation range of the first sealing member 322.

[0082] Please see Figure 6 In some embodiments, the second seal 323 includes a third sealing plate 323a and a guide post 323b. The guide post 323b is disposed on the opposite side of the third sealing plate 323a. The second air chamber 312 is recessed inward on the opposite side of the third sealing plate 323a to form a guide groove 312c. The guide post 323b is movably received in the guide groove 312c to limit the movement range of the third sealing plate 323a. Specifically, the guide groove 312c is generally crescent-shaped, and the shape of the guide groove 312c is generally determined by the projection of the area swept by the third sealing plate 323a during movement onto the inner side of the second air chamber 312.

[0083] Please see Figure 4 and Figure 5In some embodiments, the first seal 322 further includes a first mounting portion 33, which is spaced apart at one end of the second sealing plate 322b facing the third sealing plate 323a. The second seal 323 further includes a second mounting portion 34, which is disposed on the third sealing plate 323a corresponding to the first mounting portion 33. The sealing assembly 32 also includes a rotating pin (not shown), which passes through the first mounting portion 33 and the second mounting portion 34, so that the third sealing plate 323a can rotate relative to the second sealing plate 322b. That is, a hinge connection is achieved between the second sealing plate 322b and the third sealing plate 323a.

[0084] In some embodiments, the sealing assembly 32 further includes a rotary assembly portion 36, which is disposed at the connection point with the first sealing plate 322a and the second sealing plate 322b. The drive shaft 321a of the drive member 321 is connected to the rotary assembly portion 36. Specifically, the rotary assembly portion 36 is provided with a square groove (not shown), and the cross-sectional shape of the drive shaft 321a is oriented in a certain direction, allowing the drive shaft 321a to be inserted into the square groove. Thus, when the drive shaft 321a rotates, the rotary assembly portion 36 rotates accordingly, thereby driving the first sealing member 322 to rotate. The drive member 321 is a motor.

[0085] Please see Figure 3A and Figure 3B In some embodiments, the flow guiding component 20 further includes a fan 50 disposed in the second flow channel 21. The fan 50 is used to drive air from the first flow channel 11 into the second flow channel 21, thereby drying the damp clothes in the first flow channel 11.

[0086] Please see Figure 3A and Figure 3B In some embodiments, the airflow guide assembly 20 further includes a dehumidifier 60 disposed in the second flow channel 21. The dehumidifier 60 is used to reduce the air humidity in the second flow channel 21, thereby reducing the amount of humid air blown into the first flow channel 11 and thus accelerating the drying of clothing in the first flow channel 11.

[0087] Please see Figure 3A and Figure 3B In some embodiments, the flow guiding assembly 20 further includes a heater 70 disposed between the second air inlet 312a and the first flow channel 11, the heater 70 being used to heat the air entering the first flow channel 11.

[0088] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
