Abstract
Description
Technical Field
[0001] This application relates to the field of clothing processing technology, and in particular to a clothing processing device and a combined clothing processing equipment. Background Technology
[0002] A washing machine is a household appliance that uses electricity to clean clothes through mechanical action, water rinsing, and the chemical action of detergent. It greatly frees up people's hands, saves a lot of time and energy, and has become an indispensable piece of equipment in modern homes.
[0003] Currently, more and more people are choosing front-loading washing machines. Front-loading washing machines use an electric motor to rotate the drum. Clothes are repeatedly lifted and dropped within the perforated drum, undergoing a repetitive motion, and are cleaned by the combined action of detergent and water. Simultaneously, about one-third of the drum is filled with tap water, which is heated by an electric heating element to further enhance the washing effect.
[0004] In a washing machine's liquid level detection system, the air chamber plays a crucial role. Working in conjunction with a water level sensor, the air chamber precisely controls the water level. In related technologies, the air chamber is fixed to the outer drum of the washing machine using a specific connection method, such as hooking or snapping. However, this connection method makes the air chamber susceptible to loosening or detachment due to vibrations from the outer drum, thus affecting the washing machine's performance. Utility Model Content
[0005] This application discloses a clothing processing device and a combined clothing processing equipment, which can avoid the hidden danger of loose connection of the air chamber due to vibration, greatly improve the stability of the air chamber, and thus ensure that the air pressure signal received by the sensor body is stable and accurate.
[0006] To achieve the above objectives, in a first aspect, some embodiments of this application provide a garment processing apparatus, comprising:
[0007] Box;
[0008] An outer cylinder is disposed inside the box, and the outer cylinder has a water-holding cavity;
[0009] A roller, which is disposed inside the water-filling cavity of the outer cylinder and is rotatable relative to the outer cylinder;
[0010] Liquid level detection components include:
[0011] Sensor body;
[0012] An air chamber is located at the lower part of the outer cylinder, and a pressure chamber is formed inside the air chamber, which is connected to the water-containing chamber.
[0013] A pressure-conducting tube connects the sensor body and the air pressure chamber, enabling the sensor body to feed back the liquid level information in the water-filling chamber based on the air pressure change in the air pressure chamber.
[0014] The air chamber and the outer cylinder are integrally formed.
[0015] Thus, when water is added to the garment handling device, it enters the water-holding chamber of the outer drum. Since the air chamber is connected to the water-holding chamber, as the water level rises, the air in the air pressure chamber is compressed, causing the pressure inside the air chamber to change with the water level. This pressure change is then transmitted to the sensor body through a pressure-conducting pipe. The sensor body converts the pressure signal into an electrical signal and transmits it to the control system to determine the water level in the water-holding chamber, thereby controlling the water filling process of the garment handling device to ensure that water filling stops when the set value is reached. During the drainage process, as the water level drops, the pressure inside the air chamber gradually returns to normal.
[0016] By integrally molding the air chamber and outer drum, they become a single unit, thus avoiding the risk of loosening due to vibration and greatly improving the stability of the air chamber. The air chamber is stably fixed to the outer drum, enabling continuous and accurate detection of liquid level changes in the water-filled chamber of the outer drum. Because the air chamber will not shift or loosen due to vibration, the connection between its internal air pressure chamber and the water-filled chamber of the outer drum remains stable, ensuring stable and accurate air pressure sensed by the sensor. Based on a stable air pressure signal, the sensor can accurately feed back liquid level information, allowing the control system of the garment processing device to more precisely control the water level, optimize the washing process, improve washing results, and avoid over- or under-washing due to inaccurate liquid level detection, thereby enhancing the overall performance and reliability of the garment processing device.
[0017] In some embodiments of this application, the water-containing cavity includes:
[0018] main cavity;
[0019] A heating chamber, which is located at the bottom of the main cavity and communicates with the main cavity;
[0020] The air chamber is located on one side of the heating cavity along the width direction of the housing and is in communication with the heating cavity.
[0021] In this way, the air chamber can accurately sense subtle changes in water level in real time. When the garment processing device fills or drains water, the change in water level in the heating chamber is quickly transmitted to the air chamber, making the signal obtained by the sensor body more timely and accurate. This, in turn, makes the control system's judgment error on water level smaller, ensuring that the water level is always maintained at a suitable level during the washing process and guaranteeing the washing effect.
[0022] In some embodiments of this application, the air chamber includes:
[0023] The air chamber body has the air pressure cavity formed within it, and the bottom of the air chamber body has a first opening communicating with the air pressure cavity;
[0024] A cover, which is sealed over the first opening.
[0025] This greatly simplifies the overall mold structure when molding the air chamber and outer cylinder as a single unit. When manufacturing the air chamber body mold, there is no need to consider the complex molding structure between the air pressure chamber and the heating chamber; only the position and dimensional accuracy of the bottom opening need to be ensured, reducing the difficulty and cost of mold manufacturing. Moreover, the demolding process is smoother when the air chamber body and outer cylinder are molded as a single unit.
[0026] In some embodiments of this application, the air chamber body includes a portion of the bottom wall of the main cavity, a portion of the side wall of the heating cavity, and a cylindrical structure disposed outside the bottom wall of the main cavity.
[0027] In this way, the existing structural components of the water-filled chamber of the garment processing device are fully utilized, achieving the function of the air chamber without adding too many complex structures, thus reducing material costs and space occupation. This compact design improves space utilization, allowing the garment processing device to accommodate more functional components within a limited space, contributing to the miniaturization and weight reduction of the garment processing device.
[0028] In some embodiments of this application, the air chamber body has a second opening on the side wall near the heating chamber, and the air pressure chamber communicates with the heating chamber through the second opening;
[0029] The gas chamber body has a third opening on its side wall away from the heating chamber. The third opening is connected to the pressure guiding pipe. In the vertical direction, the second opening is lower than the third opening.
[0030] Thus, the second opening is located on the side wall of the air chamber body near the heating chamber, allowing the air chamber to communicate directly with the heating chamber. As part of the water-holding chamber, the water level changes in the heating chamber can be reflected in the air pressure chamber of the air chamber in a timely and accurate manner. The third opening is the channel for transmitting the air pressure information from the air pressure chamber to the sensor body. The sensor body senses accurate air pressure changes through the third opening and the pressure guide tube, thereby accurately detecting the water level and providing precise data for the water level control of the clothing processing device.
[0031] In some embodiments of this application, the cover includes:
[0032] An insertion part is provided, which can be inserted into the air pressure chamber through the first opening, and the outer wall of the insertion part is in contact with the inner wall of the air pressure chamber.
[0033] A connecting part is attached to the side of the insertion part near the first opening. Along the insertion direction of the insertion part, the connecting part abuts against the edge of the first opening and is connected to the air chamber body.
[0034] This achieves a tight connection between the cover and the air pressure chamber, helping to create a sealed air pressure environment and preventing gas leakage. At the same time, the connecting part abuts against the edge of the first opening, which limits the insertion part, ensuring that the insertion part can be accurately inserted into the appropriate position in the air pressure chamber and preventing the insertion part from being over-inserted or dislodged.
[0035] In some embodiments of this application, a positioning post is provided on the outer wall of the air chamber body, and the positioning post extends to the first opening along the insertion direction of the insertion part;
[0036] The connecting part extends to the bottom of the positioning post, and the connecting part is provided with a positioning groove. The positioning post is inserted into the positioning groove and connected to the positioning groove.
[0037] In this way, the positioning pin is inserted into the positioning groove and connected to it, realizing precise positioning and stable connection between the air chamber body and the connecting part. The shape and size of the positioning groove and the positioning pin match each other, which can limit the movement and offset of the connecting part during the installation process, ensuring the accuracy and stability of the connection.
[0038] In some embodiments of this application, the second opening is located at the bottom of the side wall of the heating chamber.
[0039] In this way, the pressure chamber and the heating chamber are connected at the lowest position, allowing the water in the heating chamber to naturally connect with the pressure chamber under the action of gravity. When the water level in the heating chamber changes, the water can affect the air pressure in the pressure chamber in a timely manner through this opening at the bottom.
[0040] In some embodiments of this application, the third opening is located at the top of the side wall of the air chamber body.
[0041] Thus, the third opening is located at the top of the side wall of the air chamber body, corresponding to the second opening located at the bottom of the side wall of the air chamber body near the heating chamber. This makes the air pressure distribution inside the air chamber body more reasonable. When the heating chamber transmits pressure changes to the air pressure chamber through the second opening, the third opening at the top can ensure that a smooth pressure transmission path is formed between the air pressure chamber and the external environment or the connected pressure guiding pipe.
[0042] In some embodiments of this application, a protective cover is provided inside the air pressure chamber at the third opening, and the bottom of the protective cover is in communication with the air pressure chamber.
[0043] In this way, the protective cover can play a certain role in blocking and filtering the gas or impurities that may enter the air pressure chamber through the third opening.
[0044] In some embodiments of this application, the outer cylinder comprises two outer cylinders, which are arranged side by side in a horizontal direction;
[0045] The rollers include two rollers, which are respectively disposed in the water-filling cavities of the two outer cylinders and are rotatable relative to the outer cylinders.
[0046] In this way, the lateral space of the garment handling unit is fully utilized, resulting in a compact overall structure. Within a limited footprint, two independent washing spaces are created, allowing for the separate washing of different types of clothing or different washing needs. The twin drums can also be used simultaneously, completing the washing of more clothes in the same amount of time, saving users time and effort. This is especially suitable for households or commercial laundry establishments with large amounts of laundry.
[0047] Secondly, some embodiments of this application also provide a combined garment processing device, comprising:
[0048] First garment processing device;
[0049] The second garment processing device is the garment processing device described in any one of the above-mentioned methods, and the second garment processing device is detachably disposed on the top of the first garment processing device. Attached Figure Description

[0069] A washing machine is a household appliance that uses electricity to clean clothes through mechanical action, water rinsing, and the chemical action of detergent. It greatly frees up people's hands, saves a lot of time and energy, and has become an indispensable piece of equipment in modern homes.
[0070] Currently, more and more people are choosing front-loading washing machines. Front-loading washing machines use an electric motor to rotate the drum. Clothes are repeatedly lifted and dropped within the perforated drum, undergoing a repetitive motion, and are cleaned by the combined action of detergent and water. Simultaneously, about one-third of the drum is filled with tap water, which is heated by an electric heating element to further enhance the washing effect.
[0071] In a washing machine's liquid level detection system, the air chamber plays a crucial role. Working in conjunction with a water level sensor, the air chamber precisely controls the water level. In related technologies, the air chamber is fixed to the outer drum of the washing machine using a specific connection method, such as hooking or snapping. However, this connection method makes the air chamber susceptible to loosening or detachment due to vibrations from the outer drum, thus affecting the washing machine's performance.
[0072] Based on this, the present application provides a clothing processing device and a combined clothing processing equipment, which can avoid the hidden danger of loosening of the connection between the air chamber and the outer cylinder due to vibration, greatly improve the stability of the air chamber installation, and thus ensure that the air pressure signal received by the sensor body is stable and accurate.
[0073] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.
[0074] Please see Figure 1 and Figure 2 This application provides a garment processing device, which includes a housing 10. The housing 10 is an important structure that supports and protects the internal components of the garment processing device. As the external structure of the garment processing device, the housing 10 is usually made of metal or plastic. The design of the housing 10 takes into account durability, heat dissipation performance, noise control, safety and maintainability.
[0075] In some embodiments, the housing 10 includes a frame, which is generally composed of multiple rods connected by welding, bolting, or other methods to form a robust three-dimensional structure, providing overall support for the garment processing device. It bears the weight of various important components of the garment processing device, such as the motor, garment drum, and transmission device, ensuring their stable position during operation and preventing displacement or damage due to component weight and operational vibration. When the garment processing device operates at high speed, especially during the spin-drying process, it effectively resists the shaking and vibration caused by centrifugal force, keeping the whole device stable and reducing noise and impact on the surrounding environment.
[0076] In some embodiments, please refer to Figure 1 and Figure 2 The housing 10 also includes a front panel 11, which is the main interface for users to operate the clothing processing device. It is usually equipped with various control buttons, displays, etc., for setting washing programs and adjusting parameters.
[0077] The front panel 11 can be a touch button or a hidden display screen, or it can retain physical buttons. This embodiment does not make any specific limitations on this.
[0078] In some embodiments, the housing 10 further includes two side panels, which are arranged opposite each other along the width direction of the housing 10. The side panels serve to protect the internal components of the clothing processing device and support the structure of the housing 10 from both sides of the housing 10. The side panels are generally relatively flat, and some are designed with some heat dissipation holes to help the clothing processing device dissipate the heat generated inside during operation.
[0079] In some embodiments, the housing 10 further includes a back panel, which is arranged opposite to the front panel 11 along the depth direction of the housing 10. The back panel serves to protect the internal components of the garment processing device and support the structure of the housing 10 from the rear. The back panel may also be fitted with some connecting components, such as brackets or hooks for fixing the garment processing device, to facilitate the installation and fixing of the garment processing device.
[0080] In some embodiments, the housing 10 further includes a top plate covering the top of the garment processing device. This top plate serves two purposes: preventing debris from falling into the garment processing device and enhancing the overall structural strength of the housing 10. The top plate can be designed as a fixed structure or a detachable structure, allowing the top plate of the garment processing device to be opened for convenient internal maintenance and cleaning.
[0081] In some embodiments, the housing 10 may be provided with a bottom plate, and the bottom plate and the top plate are arranged opposite each other along the height direction of the housing 10. Of course, some clothing processing devices may not have a bottom plate in the housing 10, and this embodiment does not specifically limit this.
[0082] In the figure, the X direction is along the width of the box 10 (also the horizontal direction in this embodiment), the Y direction is along the height of the box 10 (also the vertical direction in this embodiment), and the Z direction is along the depth of the box 10.
[0083] It should be explained that when the front panel 11 of the cabinet 10 is placed facing a person and the bottom plate is close to the ground, the height direction of the cabinet 10 refers to the vertical direction from the bottom to the top or from the top to the bottom. The width direction of the cabinet 10 refers to the horizontal direction between the left and right sides of the front. The depth direction of the cabinet 10 refers to the horizontal direction of the washing machine from front to back or from back to front.
[0084] In some embodiments, please refer to Figure 1 and Figure 2 The front panel 11 has two openings, which are arranged side by side along the width of the box 10. The openings on the front panel 11 provide a front opening channel for easy insertion and removal of clothing.
[0085] In some embodiments, please refer to Figure 2 and Figure 3The garment handling device also includes an outer drum 121, which is disposed inside the housing 10. The outer drum 121 has a water-holding cavity 1211 for holding washing water and providing a water environment for the washing process.
[0086] In some embodiments, please refer to Figure 2 and Figure 3 The garment handling device also includes a drum 122, which is located inside the water-filled cavity 1211 of the outer drum 121 and can rotate relative to the outer drum 121. It is a component for directly placing and washing clothes. The drum 122 usually has many small holes so that water can flow between the inner and outer drums 121 during the washing process, and water can be discharged into the outer drum 121 through the small holes during the spin-drying process.
[0087] In some embodiments, please refer to Figure 3 The garment processing device also includes a liquid level detection component 20, which includes a sensor body that can accurately detect the water level height of the water chamber 1211 based on the pressure change of the air chamber 21a.
[0088] The sensor contains a pressure-sensitive element, typically a diaphragm or bellows. Changes in pressure cause this element to deform. This deformation alters the sensor's internal electrical parameters (such as resistance and capacitance). Electronic circuitry then converts these changes into electrical signals, which are transmitted to the control board of the garment processing device. The control board uses these signals to determine the water level, thus achieving precise control of the water level in the garment processing device.
[0089] In some embodiments, the liquid level detection component 20 further includes an air chamber 21, which is located at the lower part of the outer cylinder 121. An air pressure chamber 21a is formed inside the air chamber 21, and the air pressure chamber 21a is connected to the water chamber 1211, so that changes in the water level in the water chamber 1211 can cause changes in the air pressure in the air pressure chamber 21a.
[0090] In some embodiments, please refer to Figure 3 The liquid level detection component 20 also includes a pressure guide tube 22, which connects the sensor body to the air pressure chamber 21a, so that the sensor body can feed back the liquid level information in the water chamber 1211 based on the air pressure change in the air pressure chamber 21a.
[0091] When water is added to the garment handling device, water enters the water-holding chamber 1211 of the outer cylinder 121. As the water level rises, the air in the air pressure chamber 21a of the air chamber 21 is compressed, and the pressure in the air pressure chamber 21a changes with the water level. This pressure change is then transmitted to the sensor body through the pressure guide pipe 22. The sensor body converts the pressure signal into an electrical signal and transmits it to the control system to determine the water level in the water-holding chamber, thereby controlling the water filling process of the garment handling device and ensuring that water filling stops when the water level reaches the set value. During the drainage process, as the water level drops, the pressure in the air chamber 21 gradually returns to normal.
[0092] In some embodiments, please refer to Figure 3 The air chamber 21 and the outer cylinder 121 are integrally formed, which ensures the sealing and stability of the connection between the air chamber 21 and the outer cylinder 121.
[0093] Thus, the air chamber 21 and the outer cylinder 121 are integrally formed, making them a single unit. This avoids the risk of loosening due to vibration, greatly improving the stability of the air chamber 21. The air chamber 21 is stably fixed to the outer cylinder 121, enabling continuous and accurate detection of liquid level changes in the water-filled chamber 1211 of the outer cylinder 121. Because the air chamber 21 will not shift or loosen due to vibration, the connection between its internal air pressure chamber 21a and the water-filled chamber 1211 of the outer cylinder 121 remains stable, ensuring a stable and accurate air pressure signal received by the sensor. Based on the stable air pressure signal, the sensor can accurately feed back liquid level information, allowing the control system of the garment processing device to more precisely control the water level, optimize the washing process, improve washing results, and avoid situations where too much or too little water is used due to inaccurate liquid level detection, thereby enhancing the overall performance and reliability of the garment processing device.
[0094] The one-piece molding can be achieved by injection molding, die casting, blow molding or compression molding, etc., and this embodiment does not make specific limitations on this.
[0095] In some embodiments, please refer to Figure 5 and Figure 7 The water-holding cavity 1211 includes a main cavity 1211a, which is the main part of the water-holding cavity 1211 and is used to hold a large amount of washing water to provide a sufficient water environment for washing clothes.
[0096] In some embodiments, please refer to Figure 5 and Figure 7The water-holding chamber 1211 also includes a heating chamber 1211b. The heating chamber 1211b is located at the bottom of the main chamber 1211a and is connected to the main chamber 1211a. This allows the heating chamber 1211b to heat the water in the main chamber 1211a to meet the water temperature requirements of different washing programs. It also ensures that the hot water circulates evenly in the two chambers, keeping the water temperature in the entire water-holding chamber 1211 relatively consistent.
[0097] In some embodiments, please refer to Figure 5 and Figure 7 The air chamber 21 is located on one side of the heating chamber 1211b along the width direction of the housing 10 and is in communication with the heating chamber 1211b.
[0098] Thus, because the heating chamber 1211b is located low, it is the area in the water-filling chamber 1211 where water level changes are most noticeable. The air chamber 21 is located on one side of the heating chamber 1211b along the width of the housing 10 and is connected to the heating chamber 1211b, enabling it to accurately detect subtle changes in water level immediately. When the garment handling device fills or drains water, the change in water level in the heating chamber 1211b is quickly transmitted to the air chamber 21, making the signal acquired by the sensor body more timely and accurate. This, in turn, reduces the error in the control system's judgment of the water level, ensuring that the water level is always maintained at a suitable level during the washing process, thus guaranteeing the washing effect.
[0099] Moreover, from the overall structural layout of the outer drum 121, the space on one side of the heating chamber 1211b is relatively unused. Placing the air chamber 21 here makes full use of the space, making the internal structure of the clothes handling device more compact and avoiding the chaotic internal structural layout of the washing machine caused by the air chamber 21 occupying other positions.
[0100] Meanwhile, the heating chamber 1211b is used to heat the washing water, and the air chamber 21 is connected to it, utilizing some of the heat from the heating chamber 1211b. In cold weather, the air inside the air chamber 21 is heated, which can prevent water vapor from condensing inside the air chamber 21 to a certain extent, avoiding the impact of condensation on the accuracy of air pressure detection, ensuring stable operation of the air chamber 21, and ensuring that the liquid level detection is not affected by the ambient temperature, thereby improving the stability of the washing machine in different seasons and environments.
[0101] Of course, in other embodiments, the air chamber 21 may also be located at the bottom of the main cavity 1211a of the water-filling cavity 1211 and communicate with the bottom of the main cavity 1211a of the water-filling cavity 1211.
[0102] In some embodiments, please refer to Figure 6 and Figure 7 The air chamber 21 includes an air chamber body 211, an air pressure chamber 21a is formed inside the air chamber body 211, and a first opening communicating with the air pressure chamber 21a is provided at the bottom of the air chamber body 211.
[0103] In some embodiments, please refer to Figure 6 and Figure 7 The air chamber 21 also includes a cover 212, which is a sealing cover provided at the first opening.
[0104] Thus, the air chamber 21 is located on one side of the heating chamber 1211b and communicates with the heating chamber 1211b. The air chamber 21 is divided into an air chamber body 211 and a cover 212. The air chamber body 211 only needs to have a first opening at the bottom, and the cover 212 is sealed and placed at the first opening. This greatly simplifies the overall mold structure when the air chamber 21 and the outer cylinder 121 are integrally formed. When manufacturing the mold of the air chamber body 211, there is no need to consider the complex forming structure between the air pressure chamber 21a and the heating chamber 1211b. Only the position and dimensional accuracy of the bottom opening need to be ensured, which reduces the difficulty and cost of mold manufacturing.
[0105] Moreover, when the air chamber body 211 and the outer cylinder 121 are integrally formed, the demolding process of the mold is smoother. The cover 212 is installed after the air chamber body 211 is formed, which will not interfere with the mold opening action when the air chamber body 211 and the outer cylinder 121 are integrally formed. There is no need to worry about the internal structure hindering the demolding when opening the mold, and the mold opening operation can be completed faster, improving production efficiency. The simplified structure makes the mold opening and closing speed faster, and more integrally formed parts of air chamber 21 and outer cylinder 121 can be produced per unit time.
[0106] Meanwhile, the cover 212 is connected to the air chamber body 211 by a sealed cover. This design facilitates the inspection, maintenance, or repair of the interior of the air chamber 21 when needed. For example, if an abnormality is found in the liquid level detection, the cover 212 can be opened to clean the interior of the air chamber body 211 or to check for damage to components without having to disassemble the entire garment processing device on a large scale, thus reducing maintenance costs and difficulty.
[0107] In some embodiments, please refer to Figure 7 The air chamber body 211 includes a portion of the bottom wall 2111 of the main cavity, a portion of the side wall 2112 of the heating cavity, and a cylindrical structure 2113 located on the outside of the bottom wall of the main cavity 1211a.
[0108] Thus, the air chamber body 211, including part of the bottom wall 2111 of the main cavity and part of the side wall 2112 of the heating cavity, makes full use of the existing structural components of the water-holding cavity 1211 of the garment processing device. Without adding too many complex structures, the function of the air chamber 21 is achieved, reducing material costs and space occupation. This compact design improves space utilization, allowing the garment processing device to accommodate more functional components within a limited space, contributing to the miniaturization and weight reduction of the garment processing device.
[0109] Moreover, the cylindrical structure 2113 is located on the outer side of the bottom wall of the main cavity 1211a. The cylindrical structure 2113 has a certain volume, which can form a stable air pressure cavity 21a. Its shape is conducive to the stable distribution of gas in the cavity, providing good conditions for accurately sensing the air pressure changes caused by water level changes. The cylindrical structure 2113 and the cover 212 are easier to seal, which can ensure good sealing performance in the air pressure cavity 21a.
[0110] Meanwhile, the connection between the air chamber body 211 and the main cavity 1211a and the heating cavity 1211b allows changes in the water level in the water-filled cavity 1211 to be directly transmitted to the air pressure cavity 21a of the air chamber 21. Part of the bottom wall 2111 of the main cavity and part of the side wall 2112 of the heating cavity directly contribute to the formation of the air chamber 21, shortening the pressure transmission path, reducing pressure loss and interference, and improving the accuracy and timeliness of liquid level detection.
[0111] In some embodiments, please refer to Figure 7 The air chamber body 211 has a second opening 2114 on its side wall near the heating chamber 1211b, and the air pressure chamber 21a is connected to the heating chamber 1211b through the second opening 2114.
[0112] In some embodiments, please refer to Figure 7 The side wall of the air chamber body 211 away from the heating chamber 1211b is provided with a third opening 2115. The third opening 2115 is connected to the pressure guide pipe 22. In the vertical direction, the second opening 2114 is lower than the third opening 2115.
[0113] It needs to be explained that, Figure 3 and Figure 4 In the illustration, the pressure guiding pipe 22 and the third opening 2115 of the air chamber 21 are in a separated state. In actual use, the pressure guiding pipe 22 and the third opening 2115 of the air chamber 21 are in a connected state.
[0114] Thus, the second opening 2114 is located on the side wall of the air chamber body 211 near the heating chamber 1211b, allowing the air chamber 21 to communicate directly with the heating chamber 1211b. The heating chamber 1211b, as part of the water-holding chamber 1211, allows changes in its water level to be reflected in the air pressure chamber 21a of the air chamber 21 in a timely and accurate manner. When the water level in the heating chamber 1211b rises or falls, water enters the air pressure chamber 21a through the second opening 2114, causing a corresponding change in the air pressure within the air pressure chamber 21a.
[0115] Meanwhile, the third opening 2115 is located on the side wall of the air chamber body 211 away from the heating chamber 1211b, and is connected to the pressure guiding pipe 22 connecting the sensor body. Vertically, the second opening 2114 is lower than the third opening 2115. The third opening 2115 is the channel for transmitting the air pressure information of the air pressure chamber 21a to the sensor body. The sensor body senses accurate air pressure changes through the third opening 2115 and the pressure guiding pipe 22, thereby accurately detecting the water level and providing precise data for water level control of the clothing treatment device. The third opening 2115 is located on the side wall of the air chamber body 211 away from the heating chamber 1211b and is higher than the second opening 2114. This allows water entering the air pressure chamber 21a to first compress the gas in the air pressure chamber 21a through the third opening 2115 into the pressure guiding pipe 22, preventing water from directly entering the pressure guiding pipe 22 through the third opening 2115 within the air chamber 21, thus affecting the accuracy of air pressure transmission and ensuring the stability and accuracy of air pressure transmission.
[0116] In some embodiments, please refer to Figure 7 and Figure 8 The cover 212 includes an insertion part 2121, which can be inserted into the air pressure chamber 21a through the first opening, and the outer wall of the insertion part 2121 is in contact with the inner wall of the air pressure chamber 21a.
[0117] In some embodiments, please refer to Figure 7 and Figure 8 The cover 212 also includes a connecting part 2122, which is connected to the side of the insertion part 2121 near the first opening. Along the insertion direction of the insertion part 2121, the connecting part 2122 abuts against the edge of the first opening and is connected to the air chamber body 211.
[0118] In the figure, direction S is the insertion direction along the insertion part 2121.
[0119] In addition, the insertion part 2121 can be adopted as follows: Figure 9 The hollow bottom structure shown can also be a solid structure; this embodiment does not specifically limit this.
[0120] Thus, the insertion part 2121 is the direct contact part between the cover 212 and the air pressure chamber 21a. It can be inserted into the air pressure chamber 21a through the first opening, and its outer wall fits against the inner wall of the air pressure chamber 21a, realizing a tight connection between the cover 212 and the air pressure chamber 21a, which helps to form a sealed air pressure environment and prevent gas leakage.
[0121] Meanwhile, the connecting part 2122 is connected to the side of the insertion part 2121 near the first opening. On the one hand, along the insertion direction of the insertion part 2121, the connecting part 2122 abuts against the edge of the first opening, which limits the insertion part 2121, ensuring that the insertion part 2121 can be accurately inserted into the appropriate position in the air pressure chamber 21a, and preventing the insertion part 2121 from being over-inserted or dislodged. On the other hand, the connecting part 2122 is connected to the air chamber body 211, firmly connecting the cover 212 and the air chamber body 211 together, making the entire structure more stable.
[0122] In some embodiments, please refer to Figure 4 The outer wall of the air chamber body 211 is provided with a positioning post 2116, which extends along the insertion direction of the insertion part 2121 to the first opening.
[0123] In some embodiments, please refer to Figure 4 and Figure 8 The connecting part 2122 extends to the lower part of the positioning post 2116. The connecting part 2122 is provided with a positioning groove 21221. The positioning post 2116 is inserted into the positioning groove 21221 and connected to the positioning groove 21221.
[0124] Thus, the positioning post 2116 is set on the outer wall of the air chamber body 211 and extends to the first opening along the insertion direction of the insertion part 2121, playing a positioning and guiding role, providing an accurate position reference for the installation of the connecting part 2122, and ensuring that the connecting part 2122 of the cover 212 can be correctly connected to the air chamber body 211.
[0125] Meanwhile, part of the connecting portion 2122 extends below the positioning post 2116 and is provided with a positioning groove 21221. The positioning post 2116 is inserted into and connected to the positioning groove 21221, realizing precise positioning and stable connection between the air chamber body 211 and the connecting portion 2122. The shape and size of the positioning groove 21221 and the positioning post 2116 are matched, which can limit the movement and offset of the connecting portion 2122 during the installation process, ensuring the accuracy and stability of the connection.
[0126] The positioning pins 2116 can be two as shown in the figure, or three, four, etc., and this embodiment does not specifically limit them. Correspondingly, the number of positioning grooves 21221 on the connecting part 2122 matches the number of positioning pins 2116.
[0127] It should be noted that the positioning post 2116 and the positioning groove 21221 can be fixed by adhesive, or by interference fit or bolt connection, etc. This embodiment does not make specific limitations on this.
[0128] In some embodiments, please refer to Figure 7The second opening 2114 is located at the bottom of the side wall of the heating chamber 1211b.
[0129] Thus, the second opening 2114 is located at the bottom of the side wall of the heating chamber 1211b, so that the pressure chamber 21a and the heating chamber 1211b are connected at the lowest position. This allows the water in the heating chamber 1211b to naturally connect with the pressure chamber 21a under the action of gravity. When the water level in the heating chamber 1211b changes, the water can affect the air pressure of the pressure chamber 21a in a timely manner through this opening located at the bottom.
[0130] Moreover, since the opening is at the bottom, water will naturally fill the opening and the part below it under normal circumstances, ensuring the effective interaction between the water and the air pressure chamber 21a. When there is any slight change in the water level in the heating chamber 1211b, the water will immediately affect the air pressure of the air pressure chamber 21a through the opening, so that the slight change in water level can be more sensitively transmitted as a change in air pressure of the air pressure chamber 21a.
[0131] In some embodiments, please refer to Figure 7 The third opening 2115 is located on the top of the side wall of the air chamber body 211.
[0132] Thus, the third opening 2115 is located at the top of the side wall of the air chamber body 211, corresponding to the second opening 2114 located at the bottom of the side wall of the air chamber body 211 near the heating chamber 1211b. This makes the air pressure distribution inside the air chamber body 211 more reasonable. When the heating chamber 1211b transmits pressure changes to the pressure chamber 21a through the second opening 2114, the third opening 2115 at the top can ensure that a smooth pressure transmission path is formed between the pressure chamber 21a and the external environment or the connected pressure guiding pipe 22.
[0133] Because the opening is at the top, the gas can flow naturally towards the opening under the action of air pressure, avoiding the situation where the pressure transmission is not smooth or unstable due to the accumulation of gas at the bottom. This is conducive to efficiently transmitting the air pressure changes in the air pressure chamber 21a to the pressure guide pipe 22 and the sensor body connected thereto. Under the action of air pressure difference, the gas will naturally flow upward and be discharged or enter through the top opening, so that the sensor body can detect the air pressure changes in the air pressure chamber 21a in a timely and accurate manner, thereby improving the response speed and accuracy of the entire water level detection system.
[0134] Meanwhile, the third opening 2115 at the top can effectively prevent liquid from entering the pressure-conducting pipe 22 connected to it before gas, because the liquid will naturally accumulate at the bottom of the gas chamber body 211 under the action of gravity, and the top opening is far away from the liquid accumulation area, which greatly reduces the possibility of liquid entering the pressure-conducting pipe 22 first.
[0135] In some embodiments, please refer to Figure 10A protective cover 213 is provided inside the air pressure chamber 21a at the third opening 2115, and the bottom of the protective cover 213 is connected to the air pressure chamber 21a.
[0136] Thus, the protective cover 213 is set inside the third opening 2115 of the air pressure chamber 21a, and its bottom is connected to the air pressure chamber 21a, forming a relatively independent protective space. On the one hand, it allows the gas in the air pressure chamber 21a to be normally transmitted to the outside world (such as the pressure guide pipe 22 connected through the third opening 2115) through the bottom of the protective cover 213. On the other hand, it can also play a certain role in blocking and filtering the gas or impurities that may enter the air pressure chamber 21a through the third opening 2115.
[0137] The protective cover 213 can be a component with a certain shape and structure, such as a mesh, a porous structure, or a cover with a specific airflow guiding structure, to achieve its function of protecting and guiding gas flow. In this embodiment, the protective cover 213 is a cylindrical structure with an open bottom.
[0138] In some embodiments, please refer to Figure 1 and Figure 2 The outer cylinder 121 includes two outer cylinders 121 arranged side by side in a horizontal direction. The roller 122 includes two rollers 122, which are respectively disposed in the water-holding chambers 1211 of the two outer cylinders 121 and can rotate relative to the outer cylinders.
[0139] Thus, the two outer drums 121 are arranged side by side in a horizontal direction, making full use of the lateral space of the garment handling unit, resulting in a compact overall structure. Within a limited footprint, two independent washing spaces are achieved, allowing for the separate washing of different types of clothing or different washing needs simultaneously. The twin drums 122 can also be used simultaneously, completing the washing of more clothes in the same amount of time, saving users time and effort. This is particularly suitable for households or commercial laundry establishments with a large volume of laundry.
[0140] This application also discloses a combined clothing processing device, which includes a first clothing processing unit, which can be a drum washing machine, a dryer, a washer-dryer combo, etc.
[0141] The modular garment processing apparatus also includes a second garment processing device, which is detachably mounted on top of the first garment processing device. In some embodiments, the second garment processing device and the first garment processing device have the same width.
[0142] The second garment processing device in this combined garment processing equipment is the garment processing device described above. Therefore, the combined garment processing equipment in this embodiment has roughly the same technical effect as the garment processing device described above. Since the technical effect of the garment processing device has been fully explained, it will not be repeated here.
[0143] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
