Abstract
Description
Technical Field
[0001] This utility model relates to clothing care, and in particular to an air dehumidification device and a clothing care machine. Background Technology
[0002] Clothes dryers, also known as garment dryers, work by blowing hot air onto clothes through a hot air module. The dry, hot air removes excess moisture from the clothes. The remaining humid air is then expelled through an exhaust vent, while the rest is dehumidified by an air dehumidifier, creating dry air. This cycle continues until the clothes are completely dry. Current garment dryers typically use a dehumidifier consisting of a cooler and a drip tray. The cooler condenses water vapor in the surrounding air into liquid water, which then drips into the drip tray under gravity, thus drying the air. However, current dehumidifiers still have limitations in their ability to dry the air completely. Utility Model Content

[0034] Another existing method is to use a low-temperature refrigerator for the entire condensation dehumidification process. However, the lower the cooling temperature, the higher the energy consumption. Furthermore, if a refrigerator with a low cooling temperature is used throughout the entire process, the energy consumption of the entire condensation dehumidification process will be high, which is not energy-efficient or environmentally friendly.
[0035] Reference Figures 1 to 3The air dehumidification device according to an embodiment of the present utility model includes a cabinet 100, a first cooler 200, a first water receiving tray 300, a second cooler 400, a second water receiving tray 500, and a control module. The cabinet 100 is provided with a receiving cavity; the first cooler 200 is disposed in the cabinet 100 and located in the receiving cavity; the first water receiving tray 300 is disposed in the cabinet 100 and located below the first cooler 200, and the bottom of the first water receiving tray 300 is provided with a first drain pipe 310; the second cooler 400 is disposed in the cabinet 100 and located in the receiving cavity; the second water receiving tray 500 is disposed in the cabinet 100 and located below the second cooler 400, and the bottom of the second water receiving tray 500 is provided with a second drain pipe 510; the control module is disposed in the cabinet 100 and electrically connected to the first cooler 200 and the second cooler 400, and the control module can control the opening and closing of the first cooler 200 and the second cooler 400 respectively; wherein the cooling operating temperature of the second cooler 400 is lower than the cooling operating temperature of the first cooler 200.
[0036] When the air dehumidifier starts working, the control module controls the first cooler 200 to start. The first cooler 200 can first perform preliminary condensation dehumidification of the air and discharge the condensate through the first water receiving tray 300 and the first drain pipe 310 to remove more moisture from the air, thus significantly reducing the humidity in the air. After a period of time, the control module controls the first cooler 200 to turn off and the second cooler 400 to turn on. The second cooler 400, which has a lower cooling temperature, can further dehumidify the air, making the air drier. The condensate produced by the second cooler 400 is discharged from the container through the second water receiving tray 500 and the second drain pipe 510. By performing condensation dehumidification at two different temperatures, the air dehumidifier's ability to dry the air can be improved, and it is relatively energy-efficient.
[0037] Specifically, compared to the method of using only a refrigerator with a lower cooling temperature for condensation dehumidification, this solution adopts staged condensation dehumidification. The energy consumption is relatively low during the first refrigerator's 200°C condensation dehumidification period, and relatively high during the second refrigerator's 400°C condensation dehumidification period, which reduces the overall energy consumption of the condensation dehumidification process.
[0038] Specifically, the control module can be a structure with control functions, such as a control circuit board or a microcontroller.
[0039] In this embodiment, a condenser fan 600 is also included. The accommodating cavity includes a main chamber 110, a first condensing chamber 120, and a second condensing chamber 130. The first condensing chamber 120 is provided with a first air inlet 121 and a first exhaust outlet 122, and the first condensing chamber 120 is connected to the main chamber 110 through the first air inlet 121 and the first exhaust outlet 122, respectively. The second condensing chamber 130 is provided with a second air inlet 131 and a second exhaust outlet 132, and the second condensing chamber 130 is connected to the main chamber 110 through the second air inlet 131 and the second exhaust outlet 132, respectively. A first cooler 200 and a first water receiving tray 300 are located in the first condensing chamber 120, and a second cooler 400 and a second water receiving tray 500 are located in the second condensing chamber 130. The condenser fan 600 is disposed in the cabinet 100 and can blow air into the first condensing chamber 120 and the second condensing chamber 130. The first cooler 200 and the first drip tray 300 are located inside the first condensing chamber 120. The condensing fan 600 can blow air into the first condensing chamber 120. When the first cooler 200 is started, it can perform preliminary air dehumidification. The second cooler 400 and the second drip tray 500 are located inside the second condensing chamber 130. The condensing fan 600 can blow air into the second condensing chamber 130. When the second cooler 400 is started, it can further dehumidify the air. The two dehumidification processes do not interfere with each other, thus improving the dehumidification effect.
[0040] In this embodiment, the second air inlet 131 is located on the cavity wall of the first condensing chamber 120. Specifically, the airflow generated by the condenser fan 600 can first enter the first condensing chamber 120 through the first air inlet 121 for preliminary condensation and dehumidification, and then return to the main chamber 110 through the first exhaust port 122. At the same time, the air in the first condensing chamber 120 can also further enter the second condensing chamber 130 through the second air inlet 131 for further dehumidification, and then return to the main chamber 110 through the second air inlet 131. This allows the airflow generated by the condenser fan 600 to enter both condensing chambers simultaneously, simplifying the equipment structure, making it compact, and saving equipment costs.
[0041] Specifically, the number of condenser fans 600 can be set according to actual needs. For example, condenser fans 600 can be set in the first condensing chamber 120 and the second condensing chamber 130 respectively to form airflow through the first condensing chamber 120 and the second condensing chamber 130; or one condenser fan 600 can form airflow in the first condensing chamber 120 and the second condensing chamber 130.
[0042] In this embodiment, a switching mechanism 700 is also included. The switching mechanism 700 is disposed in the cabinet 100 and can open or close the second air inlet 131. When the second cooler 400 is not started, the switching mechanism 700 closes the second air inlet 131. At this time, the first cooler 200 is working, and the first condenser chamber 120 dehumidifies the air. The air in the main chamber 110 enters the first condenser chamber 120 through the first air inlet 121 for preliminary dehumidification, and then the air flows back to the main chamber 110 through the first exhaust port 122. When the first cooler 200 is turned off and the second cooler 400 is started, the switching mechanism 700 opens the second air inlet 131. The air in the main chamber 110 enters the first condenser chamber 120 through the first air inlet 121, and then directly enters the second condenser chamber 130 through the second air inlet 131 for further dehumidification, and then flows back to the main chamber 110 through the second exhaust port 132. By setting the switching mechanism 700, the second condensing chamber 130 can be closed when it is not working, preventing humid air from entering the second condensing chamber 130 and affecting the dehumidification effect of the first condensing chamber 120.
[0043] In this embodiment, the switching mechanism 700 includes a switch element and a switch driver. The switch element is movably disposed on the cabinet 100 and can move to close or open the second air inlet 131. The switch driver is connected to the switch element and is used to drive the switch element to move. The switch driver is electrically connected to the control module. Specifically, the switch element can be a cover plate, which can be slidably connected to the cabinet 100 and slidably open or close the second air inlet 131. In this case, the switch driver can be, for example, an electric push rod or a hydraulic cylinder. Alternatively, the switch element can be a cover plate, which can be rotatably connected to the cabinet 100 to rotatably open or close the second air inlet 131. In this case, the switch driver can be a motor or the like, driving the switch element to rotate.
[0044] It is conceivable that in other embodiments, the switching mechanism 700 may also be, for example, an air valve, etc., without limitation.
[0045] In this embodiment, the cabinet 100 is detachably equipped with a water collection box 140. A first water receiving tray 300 is connected to the water collection box 140 via a first drain pipe 310, and a second water receiving tray 500 is connected to the water collection box 140 via a second drain pipe 510. Both the first and second water receiving trays are higher than the water collection box 140. The condensate from the first cooler 200 can be received by the first water receiving tray 300 and, under gravity, flows into the water collection box 140 through the first drain pipe 310 for collection. The condensate from the second cooler 400 can be received by the second water receiving tray 500 and, under gravity, flows into the water collection box 140 through the second drain pipe for collection. After the water collection box 140 collects a certain amount of water, the user can disassemble the water collection box 140 to empty the wastewater. The water collection box 140 allows for unified collection and discharge of condensate, reducing environmental pollution.
[0046] Specifically, the cabinet 100 is provided with a plug-in hole, and the water collection box 140 is inserted into the plug-in hole, making the water collection box 140 detachable. It is understood that in some other embodiments, the water collection box 140 may also be installed on the cabinet 100 by means of snap-fit or magnetic attraction.
[0047] In this embodiment, both the first cooler 200 and the second cooler 400 are semiconductor refrigeration chips. Using semiconductor refrigeration chips results in a relatively simple structure, smaller size, and easier operation.
[0048] Specifically, the first cooler 200 has a larger area, which can quickly and initially dehumidify a large amount of moisture; the second cooler 400 has a smaller area, which makes it easier to maintain the effect of low-temperature dehumidification.
[0049] It is conceivable that in other embodiments, the first cooler 200 and the second cooler 400 may also be other types of coolers, such as heat pump coolers.
[0050] In this embodiment, the cabinet 100 is detachably equipped with a filter 150. The filter 150 is located in the first condensation chamber 120 and between the first air inlet 121 and the first exhaust outlet 122. The filter 150 is also located in the second condensation chamber 130 and between the second air inlet 131 and the second exhaust outlet 132. The filter 150 can filter dust and lint from the air, improving air cleanliness.
[0051] Specifically, the filter 150 can be detachably installed on the cabinet 100 via a plug-in connection. It is understood that in other embodiments, the filter 150 can also be installed on the cabinet 100 via magnetic attraction or snap-fit connections.
[0052] Specifically, the filter 150 can be selected between the first air inlet 121 and the first exhaust port 122, or between the second air inlet 131 and the second exhaust port 132, or the filter 150 can be installed at two different locations.
[0053] In this embodiment, the filter 150 includes a mesh body and a mounting frame. The mesh body is wavy, and the mounting frame is connected to the outer periphery of the mesh body. The wavy shape of the mesh body allows dust and lint to accumulate in the troughs of the wavy shape, while the peaks are less prone to dust and lint buildup, preventing the mesh body from being completely blocked and thus extending its service life. Furthermore, the wavy shape also increases the air permeability area of the filter 150, improving filtration efficiency.
[0054] This utility model also discloses a garment care machine, including the aforementioned air dehumidification device and hot air module 800. The hot air module 800 is disposed in the cabinet 100 and can blow hot air into the accommodating cavity. Due to the use of the aforementioned air dehumidification device, the efficiency of the garment care machine in drying clothes can be improved.
[0055] Specifically, the main chamber 110 includes a clothing storage chamber 111 and a circulating air duct 112. The hot air module 800 blows hot air into the clothing storage chamber 111 through the lower opening. The upper end of the clothing storage chamber is connected to one end of the circulating air duct 112, and the other end of the circulating air duct 112 is connected to the first condensing chamber 120 and the second condensing chamber 130.
