[0029] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0032] Some existing drum washing machines have a drying function, which specifically installs a drying machine with a heating function on the top of the washing drum, and blows hot air into the washing drum for drying when the drying machine is turned on. In the prior art, the air inlet pipe joint of the dryer is usually made into an integrated structure with the water inlet pipe. When the washing function is turned on, tap water can enter the washing drum through the water inlet pipe. After the washing is completed, the dryer is turned on, and the drying hot air can be sent into the washing drum through the air inlet pipe. Although making the water inlet pipe and the air inlet pipe into an integrated structure can simplify the parts of the washing machine and facilitate the integration of the air inlet and water inlet at the top of the washing drum at the same time, there are certain defects: the air inlet pipe is in an open state for a long time, and water is easily splashed into the air inlet pipe during the water inlet process and flows reversely along the air inlet pipe into the dryer. Especially when the user uses the washing function alone for a long time and does not use the drying function, the water in the air inlet pipe and the dryer cannot be dried in time, and the water remains in the dryer for a long time, which easily causes the metal parts inside the dryer to rust, causing the problem of damage to the dryer.

[0033] In order to overcome the above technical problems, refer to Figure 1-2The present embodiment provides an air and water inlet module for a washing machine, comprising a main frame 1 and a water retaining baffle 2. The main frame 1 has a ventilation cavity 11 and a water passage 12 separated from each other. The ventilation cavity 11 is used to convey drying hot air, and the water passage 12 is used to convey washing water. The water retaining baffle 2 can be installed in the ventilation cavity 11 in an openable and closable manner. The opening and closing of the water retaining baffle 2 is controlled by the drying hot air. When the washing machine turns on the drying function, the drying hot air flowing in the ventilation cavity 11 can push the water retaining baffle 2 to open; when the washing machine turns off the drying function, the water retaining baffle 2 can automatically close to isolate the ventilation cavity 11.

[0034] Among them, the air inlet and water inlet module of the washing machine of this solution is installed on the top of the washing drum 8 of the washing machine, and the washing machine also includes a dryer 7. The main frame 1 has an air inlet interface and an air supply interface respectively located at both ends of the ventilation cavity 11. When installed, the air inlet interface is connected to the dryer 7, and the air supply interface is connected to the washing drum 8; the main frame 1 also includes a water inlet interface and a water outlet interface respectively located at both ends of the water pipe 12. When installed, the water inlet interface is connected to the water inlet pipe, and the water outlet interface is connected to the washing drum 8. When the dryer 7 is turned on, the drying hot air can be transported to the washing drum 8 through the ventilation cavity 11; when the water inlet is turned on, the tap water for washing can enter the washing drum 8 through the water pipe 12.

[0035] A water retaining baffle 2 is provided in the ventilation cavity 11 of the water inlet and air inlet module of this embodiment, and the opening and closing of the water retaining baffle 2 is controlled by the drying hot air. When the washing machine starts the drying function, the dryer 7 blows the hot air into the ventilation cavity 11, and the wind pressure pushes the water retaining baffle 2 to open, so as to realize the function of sending the hot air into the washing drum 8 to dry the clothes. When the drying function is not used, the water retaining baffle 2 is automatically closed to isolate the ventilation cavity 11. When the washing machine is filled with water, the tap water enters from the water pipe 12. Even if the water splashes into the ventilation cavity 11, it will be blocked by the water retaining baffle 2, so as to prevent the water from entering the dryer 7 and causing the metal parts inside the dryer 7 to rust, thereby causing the dryer 7 to be damaged.

[0036] In one embodiment, the water retaining baffle 2 includes a baffle body 21 and a rotating shaft 22 connected to the top side of the baffle body 21. Both ends of the rotating shaft 22 are rotatably connected to the main frame 1. When the drying hot air circulates, the water retaining baffle 2 can be pushed to swing up and open; when the washing machine turns off the drying function, the water retaining baffle 2 automatically swings down and closes under the action of the partition body 21's own gravity.

[0037] The baffle body 21 is the main part of the water-retaining baffle 2, and its size and shape should be suitable for installation in the ventilation cavity 11 to effectively prevent water from entering the ventilation cavity 11. The water-retaining baffle 2 is rotatably installed, which is a simple and effective design that ensures that the ventilation cavity 11 is completely closed when the drying function is not used to prevent water from entering, and has the advantages of being easy to implement and low cost.

[0038] In one embodiment, referring to Figure 3-4 The ventilation cavity 11 includes a first ventilation section and a second ventilation section which are connected to each other. The first ventilation section is close to the air inlet side of the entire ventilation cavity 11, and the second ventilation section is close to the air outlet side of the entire ventilation cavity 11. The radial dimension of the second ventilation section is larger than the radial dimension of the first ventilation section. A water-blocking step 111 is formed at the connection between the first ventilation section and the second ventilation section, and the water-blocking baffle 2 is installed on the second ventilation section.

[0039] The water-blocking step 111 formed at the connection between the first ventilation section and the second ventilation section is an important waterproof design. When the washing machine is filled with water, even if a small amount of water splashes into the second ventilation section of the ventilation cavity 11 and reaches the bottom surface of the second ventilation section, it will be blocked by the water-blocking step 111, preventing the water from penetrating into the first ventilation section through the gap between the water-blocking baffle 2 and the ventilation cavity 11 and entering the dryer 7. Therefore, the design of the water-blocking step 111 can enhance the waterproof effect.

[0040] In one embodiment, the water-blocking step 111 is provided with a first accommodating groove 112 facing the first ventilation section, and a first magnetic component 3 is arranged in the first accommodating groove 112; the water-blocking baffle 2 is provided with a second magnetic component 5 corresponding to the first magnetic component 3, and when the water-blocking baffle 2 is closed, the first magnetic component 3 and the second magnetic component 5 are attracted to each other.

[0041] The size and shape of the first accommodating groove 112 should match the first magnetic component 3 to ensure that the magnetic component can be firmly installed therein. The position and size of the second magnetic component 5 should match the first magnetic component 3 to ensure that the two can be accurately aligned and attracted when the water retaining baffle 2 is closed. When the water retaining baffle 2 is closed, the first magnetic component 3 and the second magnetic component 5 will attract each other and fit tightly to form a tight sealing structure. This magnetic attraction effect can not only enhance the sealing of the water retaining baffle 2 and prevent water or moisture from penetrating into the ventilation cavity 11 through the gap, but also ensure that the water retaining baffle 2 can remain stable when closed and is not easily shaken by the vibration of the washing machine when it is working, thereby ensuring waterproofness.

[0042] In one embodiment, a second receiving groove 23 is provided on a side of the water retaining baffle 2 facing the water retaining step 111 , and the second magnetic attraction member 5 is disposed in the second receiving groove 23 .

[0043] A second receiving groove 23 is provided on the side of the water retaining baffle plate 2 facing the water retaining step 111. The size and shape of the second receiving groove 23 correspond to the second magnetic member 5 to ensure that the second magnetic member 5 can be firmly installed therein and will not fall off due to vibration or external force. The provision of the second receiving groove 23 can provide an installation space for the second magnetic member 5 and ensure the reliability of the installation of the second magnetic member 5.

[0044] In one embodiment, the first magnetic attraction member 3 is an electromagnet, and the second magnetic attraction member 5 is a ferromagnetic body.

[0045] Specifically, the first magnetic member 3 is an electromagnet, and whether it is attached with magnetism can be electrically controlled. When installed, it is electrically connected to the control circuit of the washing machine; the second magnetic member 5 is a ferromagnetic body, such as iron or iron alloy, which itself does not have magnetism, but can be magnetized and attracted. When the dryer 7 is turned on, the control circuit of the washing machine can automatically cut off the power of the first magnetic member 3, so that it loses its magnetism, and the flowing hot air can easily push the water retaining baffle 2 open; when the dryer 7 is turned off, the first magnetic member 3 is automatically powered on, so that it can use magnetic force to tightly attract the second magnetic member 5 on the closed water retaining baffle 2, thereby achieving the purpose of fixing the water retaining baffle 2.

[0046] This structural design can ensure that when the dryer 7 is turned on, the hot air can smoothly push open the water retaining baffle 2; after the dryer 7 is turned off, the water retaining baffle 2 can be fixed to ensure waterproof performance.

[0047] In one embodiment, a first waterproof gasket 4 is provided on a side of the waterproof step 111 facing the first ventilation section, and the first magnetic attraction member 3 is completely covered by the first waterproof gasket 4 .

[0048] The first waterproof gasket 4 can improve the waterproof capability when the water retaining baffle 2 is closed, and protect the first magnetic attraction member 3 from being affected by a humid environment.

[0049] In one embodiment, a second waterproof gasket 6 is provided on the side of the water retaining baffle 2 facing the water-proof step 111, and the second magnetic attraction member 5 is completely covered by the second waterproof gasket 6. When the water retaining baffle 2 is closed, the first waterproof gasket 4 fits tightly with the second waterproof gasket 6.

[0050] Similarly, providing the second waterproof gasket 6 can improve the waterproof capability when the water retaining baffle 2 is closed, and protect the second magnetic attraction member 5 from the influence of the humid environment.

[0051] In one embodiment, the main frame 1 includes a water inlet pipe 121 and a water outlet pipe 122 , and the water conduit 12 passes through the water inlet pipe 121 and the water outlet pipe 122 .

[0052] The water inlet pipe 121 can be provided to facilitate connection with a water pipe, and the water outlet pipe 122 can be provided to facilitate smooth water guidance into the washing tub 8.

[0053] On the other hand, a washing machine is provided, comprising the above-mentioned washing machine air and water inlet module.

[0054] Similarly, based on the air and water inlet module of the washing machine of this embodiment, when the washing machine of this embodiment starts the drying function, the dryer 7 blows hot air to the ventilation cavity 11, and the wind pressure pushes the water retaining baffle 2 to open, so as to realize the function of sending hot air into the washing drum 8 to dry the clothes. When the drying function is not used, the water retaining baffle 2 automatically closes to isolate the ventilation cavity 11, and when the washing machine is filled with water, tap water enters from the water pipe 12. Even if water splashes into the ventilation cavity 11, it will be blocked by the water retaining baffle 2, so as to prevent water from entering the dryer 7 and causing the metal parts inside the dryer 7 to rust, thereby causing the dryer 7 to be damaged.
