Description

Technical Field

[0001] This application relates to the technical field of dehumidifiers, and in particular to a household dehumidifier. Background Technology

[0002] A household dehumidifier is an electrical appliance used to reduce indoor humidity and improve the living environment. It mainly removes excess moisture from the air through condensation or adsorption. In some humid regions of my country, especially during the plum rain season in the south and coastal areas, when the air humidity exceeds 60%, it not only leads to the proliferation of mold, dust mites, and bacteria, causing health problems such as allergies, asthma, and respiratory infections, but also damages indoor walls, furniture, and appliances. Therefore, dehumidifiers have become an essential household appliance in humid environments. Dehumidifiers can control indoor humidity within a healthy range of 40% to 60%, preventing mold growth, dampness, and odors. They can also assist in drying clothes and improve the efficiency of air conditioning. Currently, 99% of household dehumidifiers on the market use compression refrigeration for dehumidification. This involves circulating refrigerant to cool the air, causing condensation, collecting the moisture, and then expelling dry air. However, due to the limited capacity of the dehumidifier's water tank, it typically shuts off automatically once the tank is full. This is insufficient for busy working professionals who need to stay in a humid environment for extended periods. Users usually turn on the dehumidifier before leaving home in the morning, hoping for a dry and comfortable environment when they return. However, since the water tank is already full and the machine shuts off automatically in the morning, the machine remains idle for most of the time before the user arrives home. During this off-peak period, the indoor humidity rises again, leaving the user with a damp environment upon arrival, significantly diminishing the dehumidification experience. Furthermore, placing the dehumidifier near the floor drain limits the dehumidification area. Secondly, when users want to quickly and efficiently dehumidify different areas, they often need to move the entire machine. During the movement, the water inside the water tank is easily shaken and splashed out, wetting the floor, carpet or furniture, which increases the cleaning work. Or, in order to avoid water spillage, the water in the water tank needs to be emptied before moving the main unit, or the water tank needs to be carried along. This process is cumbersome and troublesome, which seriously affects the convenience of mobile dehumidification. Furthermore, with the increasing number of pet-owning families, pet hair and dander (especially cat and dog hair) are easily sucked into the dehumidifier fan and adhere tightly to the dust filter. In the short term, they will adhere to the surface of the dust cover, affecting the fan's airflow and reducing dehumidification efficiency. In the long term, the hair will penetrate the dust cover and adhere to the fins of the internal evaporator and condenser, seriously affecting heat exchange. Summary of the Invention

[0003] One of the purposes of this application is to provide a household dehumidifier that addresses the problem of limited water storage and frequent water spillage during transport in current household dehumidifiers on the market.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a household dehumidifier, comprising a casing, a dehumidification component inside the casing, a chassis, and a water storage tank. The chassis is located at the bottom of the casing, and a detachable water storage tank is located on one side of the top of the chassis for water storage. A dust cover is detachably installed on the top of the outer side of the casing. Spare water storage components are located on both sides of the bottom of the casing to increase the water storage capacity of the dehumidifier. The water storage components are connected to the water storage tank through a water outlet component. When the water level inside the water storage tank reaches a certain height, the water inside will flow into the water storage components for storage. The top of the water storage tank is sealed with a cover plate, and a handle is also provided on its exterior.

[0005] Preferably, a protruding plate is integrally installed at the bottom of the dust cover, and a cleaning cover is detachably installed at the top of the protruding plate. This cover is used to scrape dust off the outside of the dust cover, ensuring that the entire machine can perform continuous and efficient dehumidification.

[0006] Preferably, the dehumidification assembly includes a compressor, a fan, an evaporator, and a condenser. A mounting bracket is provided on the outside of the fan and connected to the inner wall of the casing. An evaporator and a condenser are sequentially arranged at the top of the fan. An expansion valve is provided on the connecting pipe between the evaporator and the condenser. A compressor is located at the bottom of the fan, with its suction port connected to the outlet pipe of the evaporator and its discharge port connected to the inlet pipe of the condenser. A water collection box is located below the evaporator and the condenser. A connecting pipe is provided on the outside of the water collection box, and a float is located at the bottom of the connecting pipe. The connecting pipe passes through a through hole in the cover plate, and the float at the bottom of the connecting pipe is located inside the water storage tank.

[0007] Preferably, the bottom of the cleaning cover is provided with a mounting block that engages with the mounting groove at the top of the protruding plate, and the cleaning cover is U-shaped when viewed from above, and it engages with the outer side of the body. The inner side of the cleaning cover is a recessed structure, and its surface is evenly distributed with ventilation holes. The position of the ventilation holes corresponds to the rectangular holes on the dust cover. A sliding groove is provided below the interior of the recessed structure inside the cleaning cover. A rotating cleaning component is provided inside the sliding groove, and the rotating cleaning component is pulled and moved by a pulling mechanism. Scraping teeth are evenly distributed at the bending positions on both sides of the cleaning cover.

[0008] Preferably, the water storage component includes two symmetrically arranged collection mechanisms. The collection mechanisms are U-shaped and engage with both sides of the body. A reserved opening is provided on the upper inner side of the collection mechanism, and a water outlet is provided on the outer side of the collection mechanism for water discharge. The position of the reserved opening corresponds to the position of the handle and the water outlet component.

[0009] Preferably, the water outlet assembly includes a water outlet pipe and a one-way valve, the top end of the water outlet pipe is connected to one side of the one-way valve, and the other side of the one-way valve is connected to an outlet on the outer wall of the water storage tank.

[0010] Preferably, the rotating cleaning assembly includes a rotating brush, a moving block, and a rotating gear. The moving block is connected to the upper and lower positions of the rotating brush's central shaft via bearings, and the moving block is connected to a pulling mechanism. A rotating gear coaxially connected to the rotating brush is also provided on the outer side of the moving block. The rotating gear meshes with a toothed block inside the slide groove. The toothed block is provided on one side inside the slide groove and is distributed in a "U" shape.

[0011] Preferably, the pulling mechanism is symmetrically arranged on both sides of the recessed structure inside the cleaning cover, and includes a driving body, a connecting shaft, a winding shaft and a pull wire. The top end of the driving body is coaxially connected to the connecting shaft, and the winding shaft is installed at the upper and lower positions of the connecting shaft. The outside of the winding shaft is wound with a pull wire, and the top end of the pull wire is connected to the outside of the moving block.

[0012] Preferably, a water level detector is also provided on the outer wall of the water collection box, and the position of the water level detector corresponds to the position of the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: (1) It is equipped with a water storage component, which includes two collection mechanisms that can be locked to the outside. When the water level inside the water tank reaches a certain height, the water source will automatically pass through the water outlet component to the inside of the two collection mechanisms for collection. After the user turns on the dehumidifier at home, there is no need to worry about the machine stopping due to the water tank being full. The machine can work for a long time, thus ensuring that the indoor humidity can be continuously controlled at the set value. There is no need to find the floor drain, and the continuous drainage effect can be achieved. It is especially friendly to the core living areas such as living room, bedroom, and study without a pre-set drain outlet, which greatly improves the flexibility of machine placement. In addition, the locking setting of the collection mechanism not only makes the machine more beautiful, but also ensures the stability of the entire machine.

[0014] (2) The top of the water tank is covered with a cover plate, and the bottom of the cover plate is sealed with a rubber strip. The cover plate can effectively prevent water from accidentally splashing into the fan or spilling outside during the movement, reducing the risk of machine failure due to water ingress, improving product durability, fundamentally eliminating the risk of soiling the floor, carpet or furniture due to water spillage, reducing the user's cleaning burden, and allowing the user to move the dehumidifier freely, quickly and easily in different areas.

[0015] (3) A cleaning cover is provided, which is detachable from the body. Users can match it according to their needs. The rotating cleaning component inside the cleaning cover can efficiently clean pet hair and other items on the cleaning cover and dust cover, so that the machine can maintain the best ventilation state for a long time, ensure the dehumidifier runs continuously and efficiently, save more electricity, and at the same time, users do not need to clean it frequently, reducing the time cost and operation difficulty of maintenance to a very low level.

[0030] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0032] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] Example 1 One preferred embodiment of this application, such as Figures 1 to 6As shown, a household dehumidifier includes a body 1, which includes a casing 11, a dehumidification component inside the casing 11, a chassis 13, and a water tank 14. The chassis 13 is located at the bottom of the casing 11, and a detachable water tank 14 is located on one side of the top of the chassis 13 for water storage. A dust cover 12 is detachably installed on the top outer side of the casing 11. Spare water storage components are located on both sides of the bottom of the casing 11 to increase the water storage capacity of the dehumidifier. The water storage components and the water tank 14 are connected by a water outlet component 4. When the water level in the water tank 14 reaches a certain height, the water inside will flow into the water storage components for storage. The top of the water tank 14 is sealed with a cover plate 142, and a handle 141 is also provided on its exterior.

[0034] This application provides a household dehumidifier with a water storage component. When using the machine, users can choose whether to install the water storage component according to their needs. When the machine is started, its internal dehumidification component operates to dehumidify the air. During dehumidification, water enters the water storage tank 14 for collection. When the water level in the water storage tank 14 reaches a certain height, the water outlet component 4 opens, allowing excess water to fall through the water outlet component 4 into the water storage component for collection, thus increasing the water storage capacity and ensuring the machine can operate for extended periods. Once both the water storage component and the water storage tank 14 are full, they can be disassembled to empty the water, allowing the machine to operate again.

[0035] Since the top of the water tank 14 is sealed with a cover plate 142, the water will not spill when the user moves the entire machine 1 using the rollers at the bottom of the chassis 13.

[0036] In this application, the disassembly method between the water storage tank 14 and the housing 11 can be either by increasing the roughness of the surface for engagement or by using external auxiliary parts such as buckles. This invention does not impose any restrictions on this method.

[0037] As a further preferred embodiment, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 13As shown, the dehumidification assembly includes a compressor 15, a fan 16, an evaporator 17, and a condenser 18. A mounting bracket is provided on the outside of the fan 16, connecting it to the inner wall of the casing 11. The evaporator 17 and condenser 18 are sequentially arranged at the top of the fan 16. An expansion valve is provided on the connecting pipe between the evaporator 17 and condenser 18. The compressor 15 is located at the bottom of the fan 16, with its suction port connected to the outlet pipe of the evaporator 17 and its discharge port connected to the inlet pipe of the condenser 18. A water collection box 7 is located below the evaporator 17 and condenser 18. A connecting pipe 9 is provided on the outside of the water collection box 7, and a float ball 10 is provided at the bottom of the connecting pipe 9. The connecting pipe 9 passes through a through hole in the cover plate 142, and the float ball 10 at the bottom of the connecting pipe 9 is located inside the water storage tank 14. The outlet at the bottom of the water collection box 7 corresponds to the inlet on the cover plate 142, and the cover plate 142 is made of transparent material.

[0038] The water storage component includes two symmetrically arranged collection mechanisms 3. The collection mechanism 3 is U-shaped and engages with both sides of the body 1. A reserved port 31 is provided on the upper inner side of the collection mechanism 3, and a water outlet is provided on the outer side of the collection mechanism 3 for water discharge. The position of the reserved port 31 corresponds to the position of the handle 141 and the water outlet component 4.

[0039] The water outlet assembly 4 includes a water outlet pipe 41 and a one-way valve 42. The top end of the water outlet pipe 41 is connected to one side of the one-way valve 42, and the other side of the one-way valve 42 is connected to the outlet on the outer wall of the water storage tank 14.

[0040] A water level detector 8 is also provided on the outer wall of the water collection box 7, and the position of the water level detector 8 corresponds to the position of the connecting pipe 9.

[0041] When the machine is working, the fan 16 starts, which draws humid indoor air into the casing 11 through the rectangular hole on the dust cover 12. The humid air first comes into contact with the evaporator 17 inside the casing 11. At this time, the water vapor in the air will quickly condense into water droplets on the cold evaporator 17 fins and drip into the water collection box 7. At this time, the air becomes dry and cold. The dried air then flows through the high-temperature condenser 18, where it is heated and becomes dry and warm air. Finally, it is discharged from the exhaust port on the back of the casing 11. Throughout the process, the refrigerant circulates between the compressor 15, condenser 18, expansion valve, and evaporator 17.

[0042] Water inside the water collection box 7 falls into the water storage tank 14 through the outlet at its bottom and the inlet above the cover plate 142 for storage. When the water level inside the water storage tank 14 reaches the position of the water outlet component 4, the water will fall into the collection mechanism 3 through the one-way valve 42 and the water outlet pipe 41 for collection, thereby ensuring that the entire dehumidifier can carry out continuous and efficient water storage work.

[0043] In this application, a water level detector 8 is also installed inside the collection mechanism 3. When the water level inside the collection mechanism 3 or the water tank 14 reaches the set value, the entire machine will be triggered to stop. At the same time, due to the setting of the float ball 10, it will rise with the water level. After reaching the set height, the magnet inside it will also trigger the reed switch to open and close, so as to achieve the purpose of opening and closing. Regarding the design of opening and closing, this invention does not impose any restrictions.

[0044] Example 2: For pet-owning families, users can also choose whether to use it with the cleaning cover 2. Specific usage instructions will vary depending on the situation. Figure 4 . Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, a protruding plate 121 is integrally installed on the bottom of the dust cover 12, and a cleaning cover 2 is detachably installed on the top of the protruding plate 121. The cleaning cover 2 is used to scrape dust from the outside of the dust cover 12, ensuring that the entire machine can perform continuous and efficient dehumidification.

[0045] The bottom of the cleaning cover 2 is provided with a mounting block 24 that engages with the mounting groove at the top of the protruding plate 121. The cleaning cover 2 is U-shaped when viewed from above and engages with the outer side of the body 1. The inner side of the cleaning cover 2 is a recessed structure, and its surface is evenly distributed with ventilation holes 21. The position of the ventilation holes 21 corresponds to the rectangular holes on the dust cover 12. A sliding groove 23 is provided below the interior of the recessed structure inside the cleaning cover 2. A rotating cleaning component 5 is provided inside the sliding groove 23, and the rotating cleaning component 5 is pulled and moved by the pulling mechanism 6. Scraper teeth 22 are evenly distributed at the bending positions on both sides of the cleaning cover 2.

[0046] The rotating cleaning assembly 5 includes a rotating brush 51, a moving block 52, and a rotating gear 53. The moving block 52 is connected to the upper and lower positions of the intermediate shaft of the rotating brush 51 through bearings, and the moving block 52 is connected to the pulling mechanism 6. The rotating gear 53 is also provided on the outer side of the moving block 52 and is coaxially connected to the rotating brush 51. The rotating gear 53 meshes with the toothed block 231 inside the slide groove 23. The toothed block 231 is provided on one side inside the slide groove 23 and is distributed in a "U" shape.

[0047] The pulling mechanism 6 is symmetrically arranged on both sides of the recessed structure inside the cleaning cover 2, and includes a driving body 61, a connecting shaft 62, a winding shaft 63 and a pull wire 64. The top end of the driving body 61 is coaxially connected to the connecting shaft 62, and the winding shaft 63 is installed at the upper and lower positions of the connecting shaft 62. The outside of the winding shaft 63 is wound with the pull wire 64, and the top end of the pull wire 64 is connected to the outside of the moving block 52.

[0048] After selecting a dehumidifier with a cleaning cover 2, the user simply needs to engage the mounting block 24 at the bottom of the cleaning cover 2 with the mounting groove at the top of the protruding plate 121. Once engaged, the working cycle of the pulling mechanism 6 can be set according to the program. After setting, when the dust cover 12 needs to be cleaned periodically, the two drive bodies 61 on the pulling mechanism 6 are activated, causing them to work in opposite directions. One drive body 61 drives the connecting shaft 62 at its top to rotate, which in turn causes the winding shaft 63 on it to wind up the cable 64. The other drive body unwinds the cable. During this process, the winding cable 64 pulls the moving block 52 at its top to move inside the slide groove 23, while simultaneously driving the rotating brush 51 and the rotating gear coaxially connected to its bottom. The rotating gear 53 rotates and meshes with the toothed block 231 on one side of the slide 23, causing the rotating gear 53 to rotate, which in turn drives the rotating brush 51 to rotate. When rotating, the brush cleans the rectangular holes on the surface of the dust cover 12 and the ventilation holes 21 on the surface of the cleaning cover 2. As the rotating brush 51 moves, it moves to the bent position of the cleaning cover 2. At this time, since the bent position is equipped with scraping teeth 22, the rotating brush 51 continuously contacts the scraping teeth 22 as it rotates. The scraping teeth 22 carry away the hair on the rotating brush 51, thus completing the simple cleaning work of the rotating brush 51. When the rotating brush 51 reaches the final position, the two drive bodies 61 work in opposite directions, so that the rotating brush 51 moves in the opposite direction to clean again.

[0049] In this application, the presence of the scraping teeth 22 not only carries away the hair on the rotating brush 51 to achieve the purpose of simple cleaning of the rotating brush 51 (the hardness of the scraping teeth 22 is greater than that of the rotating brush 51), but also, after the rotating brush 51 comes into contact with the scraping teeth 22, the scraping teeth 22 will move the hair attached to the surface of the rotating brush 51 to the inner side of the rotating brush 51 near the shaft for winding, so as to ensure that the rotating brush 51 can still perform continuous and efficient cleaning of the mesh when it moves in the opposite direction.

[0050] The start and stop times of the two drive bodies 61 can be controlled by a PLC or in conjunction with a timer. Each drive body 61 is controlled by a relay. When relays a and b are started simultaneously, the output of channel A is high. At this time, the drive body 61 corresponding to relay a rotates forward and the drive body 61 corresponding to relay b rotates backward. The timer is designed to work for 30 seconds (i.e., the movement time of a single rotation of the rotating brush 51) and then stop for 1-5 days (i.e., standby time). Then, relays a and b switch to output channel B high. At this time, the drive body 61 corresponding to relay a rotates backward and the drive body 61 corresponding to relay b rotates forward. The time is also 30 seconds, and then it stops for 1-5 days. Then, it switches back to channel A high. This cycle repeats to perform periodic cleaning work.
