Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laundry, and particularly provides a laundry equipment. BACKGROUND

[0002] The laundry equipment is a laundry processing equipment capable of washing, rinsing, dewatering and / or drying clothes, and some laundry equipment also adds air washing, sterilization, degerming, fragrance adding and the like functions. There are many types of laundry equipment, such as the most common drum washing machine, pulsator washing machine and washing-drying integrated machine.

[0003] Taking the drum washing machine as an example, the existing drum washing machine comprises an outer drum and an inner drum. During washing, a certain amount of water is first injected into the outer drum, and then the inner drum drives the clothes to overturn, so as to realize washing of the clothes. The principle design is to simulate the principle of a hammer hitting clothes. After washing the clothes, the outer drum and the window cushion connected with the outer drum are both wet, that is, the inner wall thereof has residual water. Long-term use is easy to breed bacteria. If only the door glass is opened to naturally dry the outer drum and the window cushion, the effect is very limited. Moreover, the window cushion contains crevice parts, which is very unfavorable to the emission of water vapor. When the user uses the drum washing machine again, the bacteria and dirt in the inner wall of the outer drum and the window cushion are easy to cause secondary pollution to the clothes, seriously affecting the washing effect and making the user experience poor. The washing-drying integrated machine at least increases a drying system on the basis of the traditional drum washing machine, so that the drum washing machine has a drying function. Some models can also realize air washing. However, although the drying system can dry the residual water in the outer drum and the window cushion after washing the clothes by means of drying, the drying system of the washing-drying integrated machine adopts an internal circulation mode. This makes the water vapor still circulate between the drying air duct and the outer drum. Moreover, the dehumidification of the washing-drying integrated machine mainly relies on the dehumidification device of the drying system. This makes it necessary to keep the drying system running to further remove the residual water in the outer drum and the window cushion after the drying program is completed. This will seriously increase the energy consumption of the washing machine and is very unfavorable to energy saving.

[0004] In the patent document with the patent number 201922216894.9, a drum washing machine is disclosed, which comprises an air inlet pipeline and an air outlet pipeline with a fan. The air inlet pipeline and the air outlet pipeline are both communicated with the outer drum. The flowing air can enter the outer drum and dry the inner surface of the outer drum and the outer surface of the inner drum. The flowing air is then discharged from the air outlet pipeline of the machine body of the drum washing machine. That is, the outer drum is dried by external air, so as to avoid breeding of dirt and bacteria. However, this drum washing machine cannot guarantee that the external dirt does not enter the drum washing machine, and still has certain safety hazards.

[0005] A ventilation structure and a washing machine are disclosed in patent document No. 201810106076.0. The ventilation structure includes a ventilation opening and a rotating body. The rotating body is arranged at the ventilation opening and rotates. The rotating body is provided with a first connecting hole penetrating in the radial direction. When the rotating body rotates, the first connecting hole can be in communication with the ventilation opening or the rotating body blocks the ventilation opening, so that the first connecting hole is selectively in communication with the ventilation opening, realizing the purpose of opening or closing the ventilation opening by rotating the rotating body. The ventilation structure can be arranged on the front panel of the washing machine shell, or arranged in the rear ventilation opening at the same time. However, when the ventilation structure is arranged only on the front panel, external dirt is easy to enter the drum washing machine from the rear ventilation opening. If the ventilation structure is also arranged in the rear ventilation opening, the drum washing machine and the outside can be completely blocked only when the two ventilation structures are closed, which is very unfavorable for the arrangement of the product structure, and seriously increases the complexity of product design. In order to realize fast drying, the washing machine also needs to be provided with a separate fan, which will occupy more internal space of the washing machine, which is not conducive to the arrangement of the structure.

[0006] Therefore, there is a need in the art for a new washing equipment to solve the above problems. SUMMARY

[0007] The present application aims to solve the above technical problems, that is, to solve the problem that the existing washing equipment with ventilation function occupies more internal space of the washing equipment due to more parts, which is not conducive to the arrangement of the structure.

[0008] The present application provides a washing equipment, which comprises a drum assembly, a valve assembly and a fan. The valve assembly comprises a blocking mechanism and a valve shell with an air inlet cavity and an air outlet cavity arranged independently. The shell of the fan is arranged together with the valve shell. The air inlet of the shell is in communication with the outside. The air outlet of the shell is in communication with the air inlet of the air inlet cavity. The air outlet of the air inlet cavity is in communication with the drum assembly through an air inlet pipeline. The air outlet cavity is connected with an air outlet pipeline which connects the outside with the drum assembly. The blocking mechanism is arranged to block the air inlet pipeline and the air outlet pipeline at the same time.

[0009] In the preferred technical scheme of the above washing equipment, the air outlet of the air inlet cavity and the air inlet of the air outlet cavity are located on the same side of the valve shell. The blocking mechanism comprises a driving motor, a first blocking piece and a second blocking piece. The output shaft of the driving motor is connected with the first blocking piece and the second blocking piece at the same time. The first blocking piece is arranged in the air inlet cavity, and the second blocking piece is arranged in the air outlet cavity. The driving motor can drive the first blocking piece and the second blocking piece to move at the same time to cover the air outlet of the air inlet cavity and the air inlet of the air outlet cavity.

[0010] In the preferred technical scheme of the laundry equipment, the driving motor is connected with the transmission shaft, the first barrier is a first barrier plate, the second barrier is a second barrier plate, the first barrier plate and the second barrier plate are arranged on the transmission shaft, and the driving motor can drive the transmission shaft to rotate so as to simultaneously rotate the first barrier plate and the second barrier plate.

[0011] In the preferred technical scheme of the laundry equipment, the transmission shaft sequentially passes through the air inlet cavity and the air outlet cavity from the outside of one side of the valve housing, and the transmission shaft is rotatably arranged on a partition plate separating the air inlet cavity and the air outlet cavity.

[0012] In the preferred technical scheme of the laundry equipment, the air inlet of the air inlet cavity and the air outlet of the air inlet cavity are located on opposite sides of the valve housing.

[0013] In the preferred technical scheme of the laundry equipment, the air inlet of the air outlet cavity and the air outlet of the air outlet cavity are located on opposite sides of the valve housing.

[0014] In the preferred technical scheme of the laundry equipment, the air outlet pipeline comprises a first air outlet pipe and a second air outlet pipe, the first air outlet pipe communicates the drum assembly with the air inlet of the air outlet cavity, and the second air outlet pipe communicates the air outlet of the air outlet cavity with the outside.

[0015] In the preferred technical scheme of the laundry equipment, an opening communicating with the outside is arranged on a front panel of a cabinet of the laundry equipment, and the second air outlet pipe communicates with the opening.

[0016] In the preferred technical scheme of the laundry equipment, an air outlet detection device is arranged at the opening.

[0017] In the preferred technical scheme of the laundry equipment, the drum assembly comprises an outer drum and a window pad connected with each other, the air inlet pipeline communicates with the window pad, and the air outlet pipeline communicates with the outer drum.

[0018] In the case of adopting the above technical scheme, the laundry equipment can realize air drying inside the drum assembly by starting the air blower to make outside air enter the air inlet pipeline and then enter the drum assembly after the laundry program of the laundry equipment is completed, and finally the air is discharged from the air outlet pipeline, so as to avoid breeding of bacteria due to residual water inside the drum assembly. In addition, the barrier mechanism can simultaneously cut off the air inlet cavity and the air outlet cavity, the casing of the air blower and the valve housing are arranged together, which can save space, facilitate overall structural arrangement of the product, and reduce complexity of product design.

[0019] Further, the driving motor drives the transmission shaft to rotate, so that the first blocking plate can cover the air outlet of the air inlet cavity to block the air inlet cavity and the cylinder assembly, and the second blocking plate can cover the air inlet of the air outlet cavity to block the air outlet cavity and the cylinder assembly. Since the air outlet of the air inlet cavity and the air inlet of the air outlet cavity are covered respectively, even if foam and / or steam is generated during the washing process of the laundry equipment, it will not enter the air inlet cavity and the air outlet cavity, that is, will not enter the valve housing. Therefore, the valve assembly can be protected from foam and steam, and the fan can also be protected from foam and steam, thereby further improving the user experience.

[0020] Further, the driving motor is arranged outside the valve housing, so that the transmission shaft extends into the valve housing to drive the first blocking plate and the second blocking plate to rotate. By such an arrangement, a structural basis is provided for the structure installation of the driving motor, and the driving motor arranged outside the valve housing will not affect the air flow, and the driving motor will also not have the safety hazard of being covered by humid air, thereby further improving the safety of the laundry equipment.

[0021] Further, the air inlet of the air inlet cavity and the air outlet of the air inlet cavity are located on opposite sides of the valve housing, which is beneficial to the arrangement of the fan and the air inlet pipeline, avoids the concentration of different parts, reduces the complexity of product design, and is beneficial to the overall structure arrangement.

[0022] Further, the air inlet of the air outlet cavity and the air outlet of the air outlet cavity are located on opposite sides of the valve housing, which is beneficial to the arrangement of the air outlet pipeline, reduces the complexity of product design, and is beneficial to the overall structure arrangement.

[0023] Further, the air outlet detection device can detect whether the air outlet pipeline is air outlet, so as to determine whether the air outlet of the laundry equipment is normal, thereby facilitating the user to know the air outlet state, being beneficial to the control of the laundry equipment, and further improving the user experience.

[0024] Further, the air inlet pipeline communicates with the window pad, and the air outlet pipeline communicates with the outer cylinder, so that external air can enter from the window pad, the window pad is first dried by air, and then the outer cylinder is dried by air, and finally the humid air is discharged through the air outlet pipeline. Therefore, the outer cylinder and the window pad can be dried at the same time, thereby avoiding secondary pollution when the user performs secondary cleaning on the clothes, and affecting the user experience.

[0029] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the present invention is described in conjunction with a drum washing machine, the technical principles of the present invention are obviously also applicable to washer-dryer combos or multi-layer garment processing equipment. Adjustments or changes to these applications do not constitute a limitation of the present invention and should all be limited to the scope of protection of the present invention.

[0031] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "connect" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Based on the background art, existing drum washing machines with ventilation functions occupy a lot of internal space due to the large number of parts, which is not conducive to the structural layout. The present invention provides a drum washing machine that aims to save space, facilitate the overall structural layout of the product, and reduce the complexity of product design.

[0033] Specifically, such as Figure 1As shown, the drum washing machine of the present application comprises a cabinet 1 and a drum assembly arranged in the cabinet 1, the drum assembly comprises an inner drum 2, an outer drum 3 and a window cushion 4, the inner drum 2 is rotatably arranged in the outer drum 3, the window cushion 4 connects the opening of the outer drum 3 with the laundry throwing opening of the cabinet 1, the inner drum 2 can be directly driven to rotate by a direct drive motor, and can also be driven to rotate by a motor through a belt. The outer drum 3 is used to contain washing water, the inner drum 2 is used to overturn the laundry, and the window cushion 4 is used to ensure the sealing between the outer drum 3 and the cabinet 1.

[0034] It should be noted that the conventional washing program of the drum washing machine includes a washing process, a rinsing process, a dehydration process and a drainage process, and in some drum washing machines, the washing program can omit the dehydration process, which does not constitute a limitation on the present application, and should be limited within the protection scope of the present application. Among them, the washing process will produce a large amount of foam due to the presence of detergent / washing powder, and after the drainage process is completed, the inner surface of the outer drum 3 and the inner surface of the window cushion 4 will have residual water.

[0035] As shown in Figures 1 to 3 , the drum washing machine further comprises a valve assembly and a fan 5, the valve assembly comprises a blocking mechanism and a valve housing 6 having an air inlet cavity 61 and an air outlet cavity 62 arranged independently of each other, and the housing 51 of the fan 5 is arranged together with the valve housing 6, the air inlet of the housing 51 is communicated with the outside, the air outlet of the housing 51 is communicated with the air inlet 61a of the air inlet cavity 61, the air outlet 61b of the air inlet cavity 61 is communicated with the drum assembly through the air inlet pipeline 7, and the air outlet cavity 62 is communicated with the air outlet pipeline 8 which communicates the outside with the drum assembly, and the blocking mechanism is arranged to simultaneously block the air inlet pipeline 7 and the air outlet pipeline 8 from the outside. The housing 51 of the fan 5 and the valve housing 6 can be integrally arranged (such as welding or integrally casting, etc.), and can also be fixed together by screws or buckles, and those skilled in the art can flexibly arrange it. In the present application, the housing 51 of the fan 5 has a fan, which is preferably a centrifugal fan, and the air inlet and air outlet of the housing 51 are preferably located on the adjacent sides of the housing 51.

[0036] In a preferred case, as shown in Figure 2 and 3 , one side of the valve housing 6 has two support arms, the housing 51 of the fan 5 is arranged on the two support arms, and each support arm is provided with a threaded hole, the housing 51 of the fan 5 is provided with a mounting ear corresponding to the support arm, the mounting ear forms a threaded hole or a through hole corresponding to the position of the threaded hole on each support arm, and the housing 51 of the fan 5 and the support arm are connected together by screws. When the fan 5 adopts a centrifugal fan 5, the air inlet of the housing 51 of the fan 5 is preferably located on the side of the housing 51 away from the support arm, so as to avoid the influence of the support arm on the air inlet of the fan 5.

[0037] In the above, as shown in Figure 2 and 3 The air inlet 61a and the air outlet 61b of the air inlet chamber 61 and the air inlet 62a and the air outlet 62b of the air outlet chamber 62 are formed on the valve shell 6, and those skilled in the art can flexibly set the positions of the air inlet 61a and the air outlet 61b of the air inlet chamber 61 and the air inlet 62a and the air outlet 62b of the air outlet chamber 62 on the valve shell 6 in actual application. In a preferred case, the air outlet 61b of the air inlet chamber 61 and the air inlet 62a of the air outlet chamber 62 are located on the same side of the valve shell 6, the air inlet 61a of the air inlet chamber 61 and the air outlet 61b of the air inlet chamber 61 are located on the opposite side of the valve shell 6, and the air inlet 62a of the air outlet chamber 62 and the air outlet 62b of the air outlet chamber 62 are located on the opposite side of the valve shell 6. For example, the air inlet 61a of the air inlet chamber 61 and the air outlet 62b of the air outlet chamber 62 are located on the left side of the valve shell 6, and the air outlet 61b of the air inlet chamber 61 and the air inlet 62a of the air outlet chamber 62 are located on the right side of the valve shell 6.

[0038] Preferably, as shown in Figure 2 and 3As shown, the blocking mechanism comprises a driving motor 91, a first blocking piece 92 and a second blocking piece 93, the output shaft of the driving motor 91 is connected with the first blocking piece 92 and the second blocking piece 93 at the same time, the first blocking piece 92 is arranged in the air inlet cavity 61, the second blocking piece 93 is arranged in the air outlet cavity 62, the driving motor 91 can drive the first blocking piece 92 and the second blocking piece 93 to move at the same time so as to cover the air outlet 61b of the air inlet cavity 61 by the first blocking piece 92 and cover the air inlet 62a of the air outlet cavity 62 by the second blocking piece 93. The driving motor 91 can be a rotary motor which finally outputs rotary force, or can be a linear motor which finally outputs linear driving force. For example, in a preferred case, the driving motor 91 is connected with a transmission shaft, the first blocking piece 92 is a first blocking plate, the second blocking piece 93 is a second blocking plate, the first blocking plate and the second blocking plate are arranged on the transmission shaft, and the driving motor 91 can drive the transmission shaft to rotate so as to drive the first blocking plate and the second blocking plate to rotate at the same time. That is, the driving motor 91 is a rotary motor, and the driving motor 91 can drive the transmission shaft to rotate, the transmission shaft drives the first blocking plate and the second blocking plate to rotate at the same time, and the driving motor 91 drives the transmission shaft to rotate so that the first blocking plate can cover the air outlet 61b of the air inlet cavity 61 to realize the blocking of the air inlet pipeline 7, and at the same time, the second blocking plate can cover the air inlet 62a of the air outlet cavity 62 to realize the blocking of the air outlet pipeline 8. Since the air outlet 61b of the air inlet cavity 61 and the air inlet 62a of the air outlet cavity 62 are covered respectively, even if foam is generated during the washing process of the drum washing machine, the foam will not enter the air inlet cavity 61 and the air outlet cavity 62, and if the drum washing machine has a steam washing function, the steam generated by the drum washing machine can also be prevented from entering the air inlet cavity 61 and the air outlet cavity 62, so as to avoid the valve housing 6 being soaked by the foam and the steam. Further preferably, the side of the first blocking plate facing the air outlet 61b of the air inlet cavity 61 and the side of the second blocking plate facing the air inlet 62a of the air outlet cavity 62 are both provided with sealing pads, so that the first blocking plate can realize sealing when covering the air outlet 61b of the air inlet cavity 61, and the second blocking plate can also realize sealing when covering the air inlet 62a of the air outlet cavity 62. In other examples, the sealing pad on the first blocking plate can be replaced by a sealing ring which can correspond to the shape of the air outlet 61b of the air inlet cavity 61, and the sealing pad on the second blocking plate can be replaced by a sealing ring which can correspond to the shape of the air inlet 62a of the air outlet cavity 62.

[0039] Preferably, as Figure 2As shown, the transmission shaft passes through the air outlet cavity 62 and the air inlet cavity 61 from outside of one side of the valve housing 6 in sequence, and is rotatably arranged on a partition plate separating the air outlet cavity 62 and the air inlet cavity 61. In one possible case, the valve housing 6 is formed with a first through hole on the side forming the air outlet cavity 62, the partition plate is formed with a second through hole, the transmission shaft passes through the first through hole and the second through hole in sequence, the portion of the transmission shaft between the first through hole and the second through hole (i.e. the portion located in the air outlet cavity 62) is connected with the second blocking plate, and the portion of the transmission shaft passing out of the second through hole (i.e. the portion located in the air inlet cavity 61) is connected with the first blocking plate. In addition, the transmission shaft can be connected with the edge of the first blocking plate and the edge of the second blocking plate, so that the rotation of the transmission shaft achieves synchronous swinging of the first blocking plate and the second blocking plate. In addition, the opposite side of the valve housing 6 where the first through hole is arranged can be further arranged with a third through hole, and the extending end of the transmission shaft can be located in the third through hole, so that the transmission shaft can be supported by the first through hole, the second through hole and the third through hole, thereby improving the stability of the support. The driving motor 91 located outside the valve housing 6 can be connected to the cabinet 1 of the drum washing machine through a mounting bracket, or the driving motor 91 can be directly welded on the cabinet 1 of the drum washing machine. In other examples, the transmission shaft can also pass through the air inlet cavity 61 and the air outlet cavity 62 from outside of one side of the valve housing 6 in sequence.

[0040] Alternatively, the driving motor 91 is a linear motor, the first blocking member 92 is a first blocking plate, the second blocking member 93 is a second blocking plate, the valve housing 6 is formed with a first slot in communication with the air inlet cavity 61 and a second slot in communication with the air outlet cavity 62 on the same side, the first blocking plate is inserted into the first slot (the first slot is preferably arranged close to the air outlet 61b of the air inlet cavity 61), the second blocking plate is inserted into the second slot (the second slot is preferably arranged close to the air inlet 62a of the air outlet cavity 62), and the linear motor can drive the first blocking plate and the second blocking plate to move synchronously in a straight line. When it is necessary to close the air outlet 61b of the air inlet cavity 61 and the air inlet 62a of the air outlet cavity 62, the linear motor drives the first blocking plate to be inserted into the air inlet cavity 61 from the first slot, so as to cover the air outlet 61b of the air inlet cavity 61 by the first blocking plate, and simultaneously drives the second blocking plate to be inserted into the air outlet cavity 62 from the second slot, so as to cover the air inlet 62a of the air outlet cavity 62 by the second blocking plate. In the above case, the linear motor can also be replaced by a hydraulic cylinder, an air cylinder or the like.

[0041] Preferably, as Figure 1As shown, the air inlet pipeline 7 communicates with the window cushion 4, and the air outlet pipeline 8 communicates with the outer cylinder 3. Those skilled in the art can flexibly set the connection positions of the air inlet pipeline 7 and the window cushion 4 and the connection positions of the air outlet pipeline 8 and the outer cylinder 3 in actual application. Preferably, the air inlet pipeline 7 communicates with the top of the window cushion 4, and the air outlet pipeline 8 communicates with the top of the outer cylinder 3, so as to avoid water entering the pipeline when the drum washing machine is washing clothes. In one possible case, continuing to refer to Figure 1 , the air outlet pipeline 8 includes a first air outlet pipe and a second air outlet pipe. The first air outlet pipe communicates the cylinder assembly with the air inlet 62a of the air outlet cavity 62, and the second air outlet pipe communicates the air outlet 62b of the air outlet cavity 62 with the outside. After the drum washing machine ends the washing program, the controller of the drum washing machine can send a signal to the fan 5 to start the fan 5. The rotation of the fan 5 causes air to enter the cylinder assembly in sequence via the air inlet cavity 61 and the air inlet pipeline 7, realizing the air drying of the cylinder assembly, and then the moist air is discharged in sequence via the first air outlet pipe, the air outlet cavity 62, and the second air outlet pipe, so that the moist air is discharged to the outside. Preferably, an opening communicating with the outside is arranged on the front panel of the cabinet 1, and the second air outlet pipe communicates with the opening. The air inlet of the casing 51 of the fan 5 can be provided with an air filtering device capable of blocking dust from entering the fan 5 and the outer cylinder 3 and the window cushion 4. The air filtering device can adopt a structure of multiple layers of equivalent filter screens, or a structure of combination of coarse filter screens, medium filter screens, and high filter screens, or other filtering structures, which can be flexibly set by those skilled in the art in actual application. In actual application, a communication pipeline communicating with the air inlet of the casing 51 of the fan 5 can also be arranged, and then the inlet of the communication pipeline is arranged on the rear panel of the cabinet 1, so as to realize the rear-side air inlet and front-side air outlet of the cabinet 1.

[0042] Further preferably, an air outlet detection device is arranged at the opening. The air outlet detection device can be a flow sensor or other device capable of detecting air outlet. Through the air outlet detection device, it can be determined whether the drum washing machine normally executes the ventilation program. More preferably, an air outlet humidity sensor is also arranged at the opening. The air outlet humidity sensor can detect the air outlet humidity of the air outlet pipeline 8, and then an environmental humidity sensor communicating with the controller of the drum washing machine (such as wifi, Bluetooth communication, etc.) is arranged indoors. By comparing the environmental humidity detected by the environmental humidity sensor with the air outlet humidity detected by the air outlet humidity sensor, if the difference between the humidity detected by the environmental humidity sensor and the humidity detected by the air outlet humidity sensor is less than a preset humidity value (the preset humidity value can be a relative humidity value of 5%), it indicates that the air outlet humidity is consistent or close to the environmental humidity, and the drum washing machine can be stopped to execute the ventilation program.

[0043] In a preferred case, a drum humidity sensor is arranged on the outer drum 3, and a detection end of the drum humidity sensor is located in the outer drum 3 to detect the humidity in the outer drum 3. When the drum washing machine finishes washing clothes, the drum humidity sensor detects the humidity in the outer drum 3. When the humidity is greater than a set humidity threshold (for example, relative humidity 100%), it indicates that the outer drum 3 is very humid. The controller of the drum washing machine can control the drum washing machine to send a prompt to start fresh air or automatically start the fresh air function to dry the drum assembly by external air. The prompt to start fresh air can be a buzzing prompt, or the drum washing machine communicates with the user's mobile terminal (such as a mobile phone, a tablet computer, and a smart bracelet) to send a prompt message to the user's mobile terminal. The user can query the prompt message in the APP. Alternatively, the drum humidity sensor can be replaced by a window pad humidity sensor arranged on the window pad 4. A detection end of the window pad humidity sensor is located in the window pad 4 to detect the humidity in the window pad 4. The drum humidity sensor and the window pad humidity sensor can also be replaced by an odor sensor. The odor sensor can detect the odor in the drum assembly. The controller can determine whether the odor is an odor according to the detected odor. When the odor is an odor, the controller of the drum washing machine can control the drum washing machine to send a prompt to start fresh air or automatically start the fresh air function.

[0044] In the present application, a foam sensor can also be arranged in the valve housing 6 (one foam sensor can be arranged in the air inlet cavity 61 and the air outlet cavity 62 respectively, or the detection part of the foam sensor can be partially located in the air inlet cavity 61 and partially located in the air outlet cavity 62). When the drum washing machine executes a washing program or a rinsing program, the first blocking member 92 covers the air outlet 61b of the air inlet cavity 61, and the second blocking member 93 covers the air inlet 62a of the air outlet cavity 62. If the foam sensor detects foam in the valve housing 6, it indicates that the blocking mechanism fails to block the foam. At this time, the drum washing machine can send an alarm prompt to prompt the user to repair the valve assembly or contact a maintenance personnel to repair or replace the valve assembly.

[0045] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings. However, those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to related technical features without departing from the principles of the present application. The technical solutions after the changes or replacements will fall within the protection scope of the present application.
