Description

Technical Field

[0001] This utility model relates to the technical field of household dehumidifiers, and in particular to a built-in water tank structure for dehumidification and a dehumidifier thereof. Background Technology

[0002] During use, dehumidifiers employ different dehumidification modes depending on the environment. Generally, they are divided into two common dehumidification modes: continuous dehumidification and automatic dehumidification.

[0003] Automatic dehumidification mode automatically stops operation when humidity is low. Therefore, a water tank is located at the bottom of the dehumidifier. When the water level reaches a certain level, the water level sensor closes, the dehumidifier's full water indicator light illuminates, and it stops with an audible alarm. The water tank must be manually removed, the condensate drained, and then reinserted to the bottom of the dehumidifier, after which the machine resumes operation. Continuous dehumidification mode requires continuous operation, thus continuously producing condensate. This condensate is automatically drained from the drip tray via an external drain pipe connected to a water pump. This limits the dehumidifier's usability, requiring it to be placed near a sewer or in a convenient drainage location. Furthermore, the drain pump installed in the drip tray is directly controlled by a microswitch. When the microswitch is on, the drain pump starts; when it's off, it stops. The entire drainage process is not controlled by the control system, making precise control of the drainage process impossible. This control method has significant flaws and shortcomings.

[0004] In the above technical solutions, during normal operation, the dehumidifier uses a temporary or small water storage area, such as a water tray directly connected to the bottom of the condenser, as the initial condensate water receiving space for the water pump. This causes the dehumidifier to frequently start the water pump in continuous dehumidification mode, resulting in significant noise during operation. Furthermore, excessive pump starts affect the lifespan of the equipment and reduce the reliability of the pump system. New technological improvements are urgently needed to solve these problems. Utility Model Content

[0005] This utility model provides a built-in water tank structure and dehumidifier for dehumidification. In continuous dehumidification mode, a certain amount of condensate is stored in the built-in water tank and then discharged, which effectively avoids frequent water pump starts, reduces noise during operation, effectively extends the service life of the water pump and improves the reliability of the drainage system.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A built-in water tank structure for dehumidification includes a base frame, a water receiving tray for receiving and collecting condensate at the top of the base frame, and a dehumidification water tank for sliding insertion that moves back and forth laterally on the front side of the base frame below the water receiving tray. The dehumidification water tank is used to store the condensate that leaks from the water receiving tray and to empty the condensate after the dehumidification water tank is manually disassembled. The base frame on the opposite side of the dehumidification water tank is also equipped with a built-in water tank for receiving the condensate drained from the water tray; The bottom side of the water receiving tray is provided with a drain outlet for collecting condensate and discharging it. The built-in water tank is equipped with a water pump that automatically discharges the collected condensate to the outside of the machine through a connected drain hose.

[0007] Preferably, the water pump is installed on the lower bottom side of the cavity outside the built-in water tank where condensate is stored.

[0008] Preferably, the built-in water tank includes a water tank shell, the water tank shell has a cavity in the middle for storing condensate draining from the drain outlet, the top of the cavity has a top cover assembly for collecting and guiding condensate and preventing condensate from leaking out of the cavity when the whole machine is tilted, and the bottom of the cavity has a pump mounting base for installing and fixing the water pump.

[0009] Preferably, the top cover assembly includes a top shell, the outer edge of the top side of the top shell extends upward to form a water receiving groove for receiving condensate from the drain outlet, and the outer periphery of the water tank shell is also wrapped with a heat-insulating sponge layer to prevent condensation on the outer wall and to keep the condensate in the tank cavity warm. A guide plate is provided on one side of the water receiving tank, located directly below the drain outlet and inclined to facilitate the collection of condensate towards the lowest end on one side. The lowest end of the guide plate is provided with a collection trough to guide the collected condensate into the cavity of the box.

[0010] Preferably, a filter cylinder is detachably inserted into the water tank shell on the lower side of the guide plate to facilitate the introduction of condensate from the inner top port of the collection groove, and after being filtered by the circumferential filter screen, it is introduced into the cavity of the tank. The center of the filter cylinder is used to collect the impurities generated by the condensate filtration, and the outer end of the filter cylinder is provided with a handle for easy pulling.

[0011] Preferably, the collection trough is provided with a three-lobed cone-shaped positioning rib that facilitates the insertion and introduction of the filter screen cylinder into the inner top port and facilitates the passage of condensate.

[0012] Preferably, the pump body mounting base includes an L-shaped bottom cover and a positioning groove for positioning and fixing the water pump. The positioning groove is provided with an outlet that connects to the water inlet of the water pump and facilitates the discharge of condensate stored in the cavity of the housing. The water pump is also surrounded by a silicone sleeve to reduce vibration and isolate noise leakage. The positioning groove is also provided with screw posts on both sides that engage with the lugs on both sides of the silicone sleeve, making it easy for the water pump to be locked and fixed by screws.

[0013] Preferably, the L-shaped bottom cover also extends an L-shaped pump connector that connects to the outlet of the water pump and whose outer end is convenient for connection to an external drainage hose.

[0014] A dehumidifier includes a housing, wherein the housing has a built-in water tank structure for dehumidification as described above at the water receiving tray.

[0015] The beneficial effects of this utility model are: By using a built-in water tank in continuous dehumidification mode, frequent pump starts are avoided, reducing noise during operation. Meanwhile, the pump is fixed in the pump mounting bracket on the outside of the bottom of the cabinet cavity, so the pump does not need to be immersed in condensate. By reducing the number of pump starts and the problem of wiring short circuits, the risk of abnormalities caused by the pump during normal operation is reduced, effectively extending the service life of the pump and improving the reliability of the drainage system.

[0016] Furthermore, the built-in water tank is equipped with a removable filter screen. The incoming condensate is filtered through the circumferential filter screen of the filter screen and then guided into the cavity of the tank, enabling the installation and removal of the large-capacity filter screen of the water pump. The design of the flow channel also enables the internal dust-collecting filter screen, which is convenient for users to install and remove. In addition, the design of the flow channel of the guide plate and the collection groove on the top cover assembly ensures normal operation whether the water pump is installed or not, and there will be no problem of water leakage to the outside of the built-in water tank, which greatly improves the stability of the water pump operation.

[0017] In addition, the L-shaped bottom cover of the pump body mounting base is also equipped with an L-shaped pump water connector for easy connection with the external drain hose. This effectively prevents the drain hose from falling off due to external pulling, avoids secondary fixing of the pump to the drain hose, reduces production costs, and significantly improves the reliability and safety of use.

[0024] A built-in water tank structure for dehumidification, such as Figures 1 to 5As shown, the water tray 2 installed on the upper housing 1 of the dehumidifier includes a base frame 3. The top of the base frame 3 is provided with a water tray 2 for receiving and collecting condensate. The front side of the base frame 3 below the water tray 2 is provided with a dehumidifying water tank 4 that moves back and forth laterally and is used for sliding insertion. The dehumidifying water tank 4 is used to store the condensate draining from the water tray 2 and to empty the condensate after manual disassembly of the dehumidifying water tank 4. On the base frame 3 opposite the dehumidifying water tank 4, there is also an internal water tank 5 for receiving the condensate draining from the water tray 2. The bottom side of the water tray 2 is provided with a drain outlet 20 for the collected condensate to drain out. A water pump 6 is installed on the internal water tank 5 to automatically discharge the collected condensate to the outside of the whole machine through a connected drain hose. The water pump 6 is installed on the lower part of the bottom side of the cavity a of the housing where the internal water tank 5 stores condensate.

[0025] like Figures 3 to 11 As shown, the built-in water tank 5 includes a water tank shell 50. A cavity a is provided in the middle of the water tank shell 50 for storing condensate drained from the drain outlet 20. A top cover assembly 51 is provided at the top of the cavity a for collecting and guiding condensate and preventing leakage of condensate from the cavity a when the unit is tilted. A pump mounting base 52 is provided on the outer side of the bottom of the cavity a for mounting and fixing the water pump 6. The top cover assembly 51 includes a top shell 510. The outer edge of the top side of the top shell 510 extends upward to form a water receiving groove 511 for receiving condensate drained from the drain outlet. The water tank shell 50 is also wrapped with an insulating sponge layer 53 to prevent condensation on the outer wall and to keep the condensate in the cavity a warm. A water receiving groove 511 is provided on one side. A guide plate 512 is located directly below the drain outlet 20 and is inclined to facilitate the collection of condensate to the lowest end on one side. A collection channel 513 is also provided at the lowest end of the guide plate 512 to guide the collected condensate into the cavity a of the box. A filter cylinder 7 is detachably inserted into the water tank shell 50 below the guide plate 512 to facilitate the introduction of condensate from the inner top port of the collection channel 513 and the introduction of it into the cavity a of the box after filtration by the circumferential filter screen. The center of the filter cylinder 7 is used to collect the impurities generated by the filtration of condensate. A handle 70 is provided on the outer end of the filter cylinder 7 for easy pulling. A three-lobed cone-shaped positioning rib 8 is provided in the collection channel 513 to facilitate the insertion and introduction of the filter cylinder 7 into the inner top port and to facilitate the passage of condensate.

[0026] In the above structure, condensate is discharged from the drain port 20 of the water receiving tray 2 and first enters the top shell 510 of the built-in water tank 5. It is then guided into the cavity a of the tank through the water receiving groove 511. The top shell 510 includes a guide plate 512 and a collection groove 513. The vertical projection of the drain port 20 of the water receiving tray 2 is inside the guide plate 512, and the guide plate 512 is in an inclined state to facilitate the flow of condensate. A collection groove 513 is provided at the end of the guide plate 512. Its main purpose is to form a relatively sealed state between the guide plate 512 and the collection groove 513 channel and the filter screen 7. The condensate will flow from the guide plate 512 → collection groove 513 → filter screen 7 → cavity a of the tank, thus achieving filtration before pumping.

[0027] Since the filter cylinder 7 is not located at the inlet of the water pump 6, firstly, it reduces the resistance before the water pump 6 starts pumping water. Placing the filter cylinder 7 at the top ensures that the water pump 6 is only started after the tank is full of water. Secondly, placing the filter cylinder 7 at the front of the built-in water tank 5 allows for a relatively large space, enabling a larger filter structure and increased filter capacity, thus reducing the frequency of cleaning or replacing the filter cylinder 7. Thirdly, the dust collection method is designed as an internal accumulation type, ensuring that impurities are collected inside the filter cylinder 7 rather than on the outside. This makes it easier for users to replace the filter cylinder 7 when cleaning and disassembling it, and the impurities collected by the filter cylinder 7 will not settle inside the cavity a of the housing when it is removed, making it convenient for users to operate.

[0028] like Figure 3 , Figure 4 , Figure 5 , Figures 12 to 14 As shown, the pump body mounting base 52 includes an L-shaped bottom cover 520 and a positioning groove 521 for positioning and fixing the water pump 6. The positioning groove 521 has an outlet 8 that connects to the inlet of the water pump 6 and facilitates the discharge of condensate stored in the housing cavity a. The water pump 6 is also surrounded by a silicone sleeve 9 to reduce vibration and isolate noise leakage. The positioning groove 521 has lugs 90 on both sides that engage with the silicone sleeve 9, facilitating the locking of the water pump 6 with screws. An L-shaped pump connector 11 extends from the L-shaped bottom cover 520 to connect to the outlet of the water pump 6 and facilitates connection to an external drain hose. In use, the water pump 6 is assembled with the silicone sleeve 9. One end of the silicone sleeve 9 is fully open, and the other end is partially open. Both ends are designed with mounting lugs 90 to be fixed with the screws 10, with only two points of contact, to reduce the transmission of vibration generated by the operation of the water pump 6. Meanwhile, to reduce risks, the water pump 6 is placed horizontally, ensuring that the water inlet of the water pump 6 is horizontal and that it is on the same axis as the drain outlet after installation. After installation, the L-shaped pump water connector 11 will be locked, and there will be no risk of the drain hose falling off without removing the L-shaped bottom cover 520, greatly improving the stability of the drain hose connected to the water pump 6.

[0029] In this embodiment, during use, the built-in water tank 5 is specifically designed to supply condensate to the water pump 6, reducing the need for frequent starts of the water pump 6 due to its small capacity, thus minimizing its lifespan. It serves as an intermediate storage container. Simultaneously, to reduce the entry of impurities from the condensate into the water pump 6, a filter screen 7 is designed at the inlet of the built-in water tank 5. During normal operation, the condensate first passes through the filter screen 7 before entering the cavity a of the tank. Furthermore, as... Figure 8 As shown, the filter cylinder 7 mainly consists of an outer filter screen 71 and two sealing rings 72. After the outer filter screen is installed, the sealing rings will cooperate with the installation port to seal, preventing condensate from flowing along the filter screen to the outside of the built-in water tank 5. In order to facilitate the installation of the filter cylinder 7, a three-lobed cone-shaped positioning rib 8 is provided in the collection groove 513 to facilitate the insertion and introduction of the filter cylinder 7. When the three-lobed cone-shaped positioning rib 8 is distributed in a circle with a structure that is smaller on the outside and larger on the inside, it helps the filter cylinder 7 to be installed in place and allows condensate to pass through.

[0030] Additionally, under normal circumstances, users are required to install the filter cartridge 7 during machine operation to improve the stability of the water pump 6. However, if the user has not properly installed the filter cartridge 7 after cleaning the filter, or if the filter cartridge 7 is not installed at all, it is generally necessary to seal the water to prevent condensate from draining to the outside of the machine. In this embodiment, when the user installs the filter cartridge 7, a seal is formed at the installation port of the filter cartridge 7, so even if condensate reaches the installation port along the filter cartridge 7, it will not leak to the outside of the water tank; when the filter cartridge 7 is not installed, if... Figure 10 and Figure 11 As shown, a water-blocking step 12 is designed at the lowest point of the built-in water tank 5 relative to the collection channel 513. The distance between this step and the lowest point of the collection channel 513 is only 8mm, and the height is greater than 4mm. In this way, when the user does not install the filter screen 7, the condensate will flow from the corresponding lowest point along the side wall into the cavity a of the box, and will not cross the water-blocking step 12 to the installation port of the filter screen 7 and leak to the outside.

[0031] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. All equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
