[0059] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, this section describes in detail the specific embodiments of the present application in conjunction with the accompanying drawings. In addition to the various embodiments described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions. Therefore, the present application is not limited to the specific embodiments disclosed in this section. The scope of protection of this application shall be based on the claims.

[0060] like Figures 1 to 22 As shown, the present application proposes a washing machine, which includes a cleaning tank 100, which is used to receive the objects to be cleaned and cleaning water; a pressing part, which is used to press the objects to be cleaned (such as clothes) in the cleaning tank 100; a pressurizing part, which is used to supply air to the pressing part to pressurize it; a suction part, which is used to suck the cleaning water from the objects to be cleaned; a pressurizing path, which connects the pressing part with the discharge outlet of the pressurizing part; a suction path, which connects the cleaning tank 100 with the suction inlet of the suction part; a gas-liquid separator 500, which is used to separate water and gas; and a control part, which is used to control the washing process, the rinsing process and the dehydration process to perform the washing operation.

[0061] The control unit may be configured to supply air to the pressing unit to perform pressure washing for pressing the objects to be washed during the washing process, and to perform suction dehydration for sucking washing water from the objects to be washed during the dehydration process. A water inlet valve for filling the washing tank 100 with water may be connected.

[0062] The washing machine further includes an air path integrated structure, which integrates at least a portion of the pressurization path and the suction path.

[0063] See also Figure 3 and Figure 4 The integrated gas path structure includes a housing 1, with a channel formed therein. The housing 1 itself defines the channel walls. Optionally, the housing 1 may include a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 may be plastic parts integrally formed by a mold. The first housing 101 and the second housing 102 may be sealingly connected, for example, by a sealing ring. The first housing 101 and the second housing 102 may each define a portion of the channel walls.

[0064] It will be appreciated that, during assembly, production, or maintenance, the aforementioned channel, even with a relatively complex sub-channel structure, can be conveniently formed by connecting the first housing 101 and the second housing 102, eliminating the need to use various joints (e.g., tees, crosses, etc.) to connect multiple pipes to form a channel with a complex flow path. Channels formed by connecting multiple pipes using various joints require clarifying the connection relationships of each pipe to ensure proper installation during assembly, production, or maintenance. Consequently, assembly is difficult, operator requirements are high, and the number of joints used is large, occupying a large amount of space and posing a high risk of leakage.

[0065] In the present application, the passage formed inside the housing 1 includes a first connection port A1, a second connection port A2, a third connection port A3, a fourth connection port A4, a fifth connection port A5, a sixth connection port A6, and a seventh connection port A7 that communicate with the outside. The first connection port A1, the second connection port A2, the third connection port A3, the fourth connection port A4, and the sixth connection port A6 can be formed in the first housing 101. The fifth connection port A5 and the seventh connection port A7 can be formed in the second housing 102.

[0066] The first connection port A1, the second connection port A2, the third connection port A3, and the fourth connection port A4 can be arranged in a row and facing the same direction, making it easier to distinguish the different connection ports and to organize the pipes connected to them. The sixth connection port A6 and the seventh connection port A7 can face the same direction. The distance between the second connection port A2 and the third connection port A3 can be smaller than the distance between the first connection port A1 and the second connection port A2 and / or the distance between the third connection port A3 and the fourth connection port A4.

[0067] The housing 1 is connected to a first actuator 11, a second actuator 12, a third actuator 13, and a fourth actuator 14. These actuators can be arranged in a row and connected to the second housing 102. Each of the first, second, third, and fourth actuators 11, 12, 13, and 14 can switch between a first state and a second state. The first, second, third, and fourth actuators 11, 12, 13, and 14, combined with the channels, form a two-position, three-way valve. In other words, the integrated gas circuit structure comprises four two-position, three-way valves. These valves have a normally open (NO) terminal, a normally closed (NC) terminal, and a common terminal (COM).

[0068] The first actuator 11, the second actuator 12, the third actuator 13 and the fourth actuator 14 may include electromagnets. The first state of each actuator may be a state where the electromagnet is powered off, and the second state of each actuator may be a state where the electromagnet is powered on.

[0069] The electromagnet includes a movable portion, a coil, and a spring. When the electromagnet is de-energized (a first state), the spring maintains the movable portion in the first position, connecting the common terminal (COM) and the normally open terminal (NO) of the two-position, three-way valve formed by each actuator and channel. When the electromagnet is energized (a second state), the movable portion moves to the second position, connecting the common terminal (COM) and the normally closed terminal (NC) of the two-position, three-way valve formed by each actuator and channel.

[0070] See also Figure 1 and Figure 2 The first actuator 11 and the channel form a 2 / 3-way valve. The channel is configured so that the normally-open end of the valve communicates with the fifth connection port A5, the normally-closed end of the valve communicates with the third connection port A3, and the common end of the valve communicates with the first connection port A1. When the first actuator 11 is in the first state, the first connection port A1 communicates with the fifth connection port A5. When the first actuator 11 is in the second state, the first connection port A1 communicates with the third connection port A3.

[0071] The first connection port A1 and the fifth connection port A5 can be set at the same end of the air path integrated structure, so as to facilitate the setting of the first actuator 11, so that the first actuator 11 can easily control the connection between the first connection port A1 and the fifth connection port A5 or the connection between the first connection port A1 and the third connection port A3 by switching the state.

[0072] The two-position, three-way valve formed by the second actuator 12 and the channel is configured such that the normally-open end of the valve communicates with the fifth connection port A5, the normally-closed end of the valve communicates with the third connection port A3, and the common end of the valve communicates with the second connection port A2. When the second actuator 12 is in the first state, the second connection port A2 communicates with the fifth connection port A5. When the second actuator 12 is in the second state, the second connection port A2 communicates with the third connection port A3.

[0073] The third actuator 13 and the channel form a 2 / 3-way valve. The channel is configured so that the normally-open end of the valve communicates with the seventh connection port A7, the normally-closed end of the valve communicates with the third connection port A3, and the common end of the valve communicates with the fourth connection port A4. When the third actuator 13 is in the first state, the fourth connection port A4 communicates with the seventh connection port A7. When the third actuator 13 is in the second state, the third connection port A3 communicates with the fourth connection port A4.

[0074] The fourth connection port A4 and the seventh connection port A7 can be set at the same end of the air path integrated structure, so as to facilitate the setting of the third actuator 13, so that the first actuator 11 can easily control the fourth connection port A4 and the seventh connection port A7 to be connected or the third connection port A3 and the fourth connection port A4 to be connected by switching the state.

[0075] The fourth actuator 14 and the channel form a 2 / 3-way valve. The channel is configured so that the normally-open end of the 2 / 3-way valve communicates with the fifth connection port A5, the normally-closed end of the 2 / 3-way valve communicates with the fourth connection port A4, and the common end of the 2 / 3-way valve communicates with the sixth connection port A6. When the fourth actuator 14 is in the first state, the fifth connection port A5 communicates with the sixth connection port A6. When the fourth actuator 14 is in the second state, the fourth connection port A4 communicates with the sixth connection port A6.

[0076] The first actuator 11 may be located at the first connection port A1 , the second actuator 12 may be located at the second connection port A2 , and the fourth actuator 14 may be located at a portion between the third connection port A3 and the fourth connection port A4 .

[0077] The pressurizing part and the suction part include a pump 400 having an air inlet end and an air outlet end. According to the state switching of each actuator of the air path integrated structure, the pump 400 can serve as both the pressurizing part and the suction part.

[0078] The pressing portion may include a first pressing portion 200 and a second pressing portion 300, which are located within the washing tank 100. The first pressing portion 200 may include a first airbag, and the second pressing portion 300 may include a second airbag. During the washing process, the control unit may control the operation of the actuator to pressure-wash the items being washed by alternately inflating the first and second airbags.

[0079] The first pressing part 200 is connected to the first connection port A1, the second pressing part 300 is connected to the second connection port A2, the air inlet end of the pump 400 is connected to the third connection port A3, the air outlet end of the pump 400 is connected to the fifth connection port A5, the air outlet of the gas-liquid separator 500 is connected to the fourth connection port A4, and the sixth connection port A6 and the seventh connection port A7 are connected to the outside atmosphere.

[0080] The gas-liquid separator 500 can be connected to the suction path and can separate the air sucked from the cleaning tank 100 from the wash water. The gas-liquid separator 500 can be equipped with a drain valve and a water level monitor. When the water level monitor detects that the water level in the gas-liquid separator 500 has reached a preset level, the drain valve can be opened to drain the liquid in the gas-liquid separator 500. During the dehydration process, the gas-liquid separator 500 can repeat the above steps multiple times to drain the wash water from the cleaning tank 100.

[0081] The washing machine may further include a muffler, comprising a muffler inlet and a muffler outlet, wherein the muffler inlet may be connected to the third connection port A3 and the muffler outlet may be connected to the fifth connection port A5. The muffler may be an expansion muffler, mainly used to reduce low-frequency noise, such as 20 Hz.

[0082] The washing machine is further provided with an opening and closing portion, which, when opened, allows the interior of the pressing portion to communicate with the outside air. The control unit is configured to open the opening and closing portion and drive the pump 400 during the dehydration process to draw the washing water contained in the washing object in the washing tank 100.

[0083] The washing machine is further provided with an external air intake for introducing external air into the washing tank 100. During the dehydration process, the control unit is configured to drive the pump 400 to draw wash water from the laundry and to draw air introduced into the washing tank 100 from the external air intake. The external air intake can be configured so that the flow rate of fluid introduced into the washing tank 100 is smaller than the flow rate of fluid drawn from the washing tank 100 by the suction unit.

[0084] The operating process of a washing machine includes a wash cycle, a rinse cycle, and a spin cycle. By switching the states of actuators 11, 12, 13, and 14 as shown in Tables 1 and 2 below, pre-pressurization, washing, and spin cycles are performed. During the wash cycle, air is supplied to the pressing section, pressing the laundry, performing pressure washing. During the spin cycle, suction spin cycles draw water from the laundry.

[0086]

[0087] Note: ○ indicates that the corresponding actuator is powered. When each actuator 11, 12, 13, and 14 is powered, the common terminal is connected to the normally closed terminal; when each actuator 11, 12, 13, and 14 is powered off, the common terminal is connected to the normally open terminal.

[0088] Table 2

[0089]

[0090] (Pre-pressurization)

[0091] When the first actuator 11 and the second actuator 12 are in the first state and the third actuator 13 and the fourth actuator 14 are in the second state, the pump 400 pre-pressurizes and inflates the first pressing portion 200 and the second pressing portion 300 .

[0092] (Washing, first airbag pressurization)

[0093] When the first actuator 11 and the third actuator 13 are in the first state and the second actuator 12 and the fourth actuator 14 are in the second state, the pump 400 draws air from the second pressing part 300 to inflate the first pressing part 200 , and the first pressing part 200 pressure-washes the objects to be cleaned in the cleaning tank 100 .

[0094] (Washing, second airbag pressurization)

[0095] When the second actuator 12 and the third actuator 13 are in the first state and the first actuator 11 and the fourth actuator 14 are in the second state, the pump 400 draws air from the first pressing part 200 to inflate the second pressing part 300 , and the second pressing part 300 pressure-washes the objects to be cleaned in the cleaning tank 100 .

[0096] Repeat the above two steps to cyclically pressurize the first pressing part 200 and the second pressing part 300, and perform pressure washing on the objects to be cleaned in the cleaning tank 100 repeatedly.

[0097] (Dehydration)

[0098] When the first, second, and fourth actuators 11, 12, and 14 are in the first state and the third actuator 13 is in the second state, the pump 400 draws air from the gas-liquid separator 500, creating a pressure differential between the cleaning tank 100 and the gas-liquid separator 500. Liquid and gas within the cleaning tank 100 enter the gas-liquid separator 500, drawing air and dehydrating the items being cleaned. It will be appreciated that while the pressure within the cleaning tank 100 decreases, the first and second pressing portions 200, 300 may inflate with air, but dehydration of the items being cleaned is not caused by the inflation and squeezing of air within the first and second pressing portions 200, 300.

[0099] The integrated gas path structure of this application forms a channel by assembling the first shell 101 and the second shell 102. Compared with the solutions of the prior art, it can improve assembly and occupy less space. In one embodiment, the dimensions of the integrated gas path structure are approximately 66mm*124mm*50mm. This avoids excessive joint connections and reduces the risk of air leakage.

[0100] While the present application has been described in detail using the above-described embodiments, it will be apparent to those skilled in the art that the present application is not limited to the embodiments described in this specification. The present application can be modified and implemented as modified embodiments without departing from the subject matter and scope of the present application as defined by the claims. Therefore, the descriptions in this specification are for illustrative purposes only and do not have any limiting meaning with respect to the present application.
