An embodiment of the present application provides a dehumidifier 1000, which will be described in detail below with reference to FIG. 1 to FIG. 10.
Referring to FIG. 1 and FIG. 2, according to an embodiment of the present application, the dehumidifier 1000 includes a housing 500. The housing 500 has an air inlet opening 510 and an air outlet opening 520. In an embodiment, the housing 500 is of a cuboid shape. Referring to FIG. 3 and FIG. 4, the dehumidifier 1000 further includes a compressor 100, a heat exchange assembly 300, and an air duct assembly 400. Referring to FIG. 5 and FIG. 6, the dehumidifier 1000 further includes a water tank assembly 200, and the water tank assembly 200 includes a mounting structure 210 and a water tank 220. It should be noted that the compressor 100, the heat exchange assembly 300, the air duct assembly 400, the mounting structure 210, and the water tank 220 are all arranged in the housing 500, so that the housing 500 can protect the air duct assembly 400, the heat exchange assembly 300, and the like therein and makes the appearance of the dehumidifier 1000 more aesthetic.
Referring to FIG. 3, the heat exchange assembly 300 includes an evaporator and a condenser arranged side by side. The air duct assembly 400 includes a volute 410, a motor, and a wind wheel. The motor is drive-connected to the motor, and both of them are arranged in the volute 410. The motor is configured to drive the wind wheel to rotate to generate a suction force that causes air to flow into the volute 410. It should be noted that the compressor 100 is connected to the evaporator and the condenser to form a refrigerant circulation loop. An air inlet side of the evaporator faces the air inlet opening 510 of the housing 500, and an air outlet side of the evaporator faces an air inlet side of the condenser. An air inlet of the volute 410 faces an air outlet side of the condenser, and the air outlet 411 of the volute 410 faces the air outlet opening 520 of the housing 500.
It can be understood that in the refrigerant circulation loop, a temperature of the evaporator is lower than the temperature of the condenser. Therefore, when the dehumidifier 1000 is operating in a room, hot and humid air in the room enters the evaporator from the air inlet side of the evaporator through the air inlet opening 510 of the housing 500, and the evaporator condenses a portion of moisture in the hot and humid air into water droplets, so that the humidity and temperature of the hot and humid air decreases, and the hot and humid air becomes dry and cold air, which is discharged from the air outlet side of the evaporator. Then, the dry and cold air enters the condenser from the air inlet side of the condenser, and the condenser heats the dry and cold air, so that a temperature of the dry and cold air rises and the dry and cold air becomes dry and hot air, which is discharged from the air outlet side of the condenser. The dry and hot air then enters the volute 410 from the air inlet of the volute 410, flows in an air duct of the volute 410, and is discharged from the air outlet 411 of the volute 410. The dry and hot air discharged from the air outlet 411 of the volute 410 finally returns to the room through the air outlet opening 520 of the housing 500. It can be understood that the dehumidifier 1000 continuously performs the above working cycle on air in the room during operation to adjust air in the room to a suitable humidity.
Referring to FIG. 3 and FIG. 4, it should be noted that the air outlet 411 of the volute 410 faces upward. Referring to FIG. 1 and FIG. 2, in this case, the air outlet opening 520 of the housing 500 is arranged on an upper end surface of the housing 500. It can be understood that the above configuration allows the dry and hot air discharged from the air outlet 411 of the volute 410 and the air outlet opening 520 of the housing 500 to be blown upward, so that the dry and hot air can be spread in the room more quickly. Meanwhile, the dry hot air is effectively prevented from blowing directly to the user, thereby bringing a better dehumidification experience to the user.
Referring to FIG. 1 and FIG. 2, it should be noted that the dehumidifier 1000 has a first direction and a second direction forming an included angle with the first direction, i.e., the first direction and the second direction are different from each other. Referring to FIG. 3, in the first direction of the dehumidifier 1000, the mounting structure 210 is located on one side of the compressor 100. The heat exchange assembly 300 is located above the mounting structure 210. The evaporator and the condenser are arranged above the mounting structure 210. The air duct assembly 400 is arranged side by side with the heat exchange assembly 300 in the second direction of the dehumidifier 1000, and both of them are located above the mounting structure 210. It should be noted that the heat exchange assembly 300, the air duct assembly 400, the mounting structure 210, and the water tank 220 are located on the same side of the compressor 100. It can be understood that in the above configuration, the mounting structure 210, the water tank 220, the air duct assembly 400, and the heat exchange assembly 300 are located in an independent space on one side, and the compressor 100 is located in an independent space on the other side. Such a skillful design of the internal structure of the dehumidifier 1000 reduces the overall height and therefore the volume and weight of the dehumidifier 1000, making it convenient for a user to use and store. Because the overall height is reduced, the number of layers of dehumidifiers 1000 according to an embodiment of the present application that a common container for shipment can store is greater than that of conventional products. In addition, in the above configuration, the water tank assembly 200 can occupy a whole space below the air duct assembly 400, the compressor 100, and the heat exchange assembly 300, so the water tank assembly 200 can effectively use the total depth inside the dehumidifier 1000 and can be enlarged to effectively increase the water storage capacity, reduce the frequency of pouring water by the user, and improve user experience. In addition, the compressor 100 is located in an independent space on a lateral side of the mounting structure 210, the water tank 220, the evaporator, and the condenser, which is conducive to heat dissipation of the compressor 100, thereby improving the operating performance of the compressor 100. To sum up, the overall performance of the dehumidifier 1000 is improved.
Referring to FIG. 4, a water collect tray 800 is arranged between the water tank assembly 200 and the evaporator and condenser, and the water collect tray 800 has a water collecting space in communication with the water tank 220. It can be understood that the water droplets generated by the hot and humid air passing through the evaporator accumulate in the water collecting space of the water collect tray 800, and enter the water tank 220 from the water collecting space for storage. It should be noted that the water collect tray 800 has a drain joint 811 configured to communicate the water collecting space with outside. It can be understood that the water storage space of the water tank 220 is limited, and when the water tank 220 is full of water, the user can connect a drain pipe to the drain joint 811 to discharge the water in the water collecting space through the drain joint 811 and the drain pipe.
Referring to FIG. 2, the housing 500 has a first groove 530, and the drain joint 811 passes through the housing 500 and is located in the first groove 530. In the above configuration, the drain joint 811 can be concealed to a certain extent, making the entire dehumidifier 1000 aesthetic. It should be noted that the housing 500 has a stopper member 540, and one end of the drain joint 811 is detachably connected to the stopper member 540. When the user does not need to discharge the water in the water collecting space through the drain joint 811, the user can connect the stopper member 540 to the end of the drain joint 811 to prevent the water in the water collecting space from being discharged through the drain joint 811. When the user needs to discharge the water in the water collecting space through the drain joint 811, a user can disconnect the stopper member 540 from the end of the drain joint 811 and connect a drain pipe to the end of the drain joint 811, so that the water in the water collecting space can be discharged through the drain joint 811 and the drain pipe.
Referring to FIG. 3 and FIG. 4, according to an embodiment of the present application, the dehumidifier 1000 further includes an electrical control box 700 arranged at a position higher than the compressor 100. It can be understood that an electrical control board is provided in the electrical control box 700, and an operational status of the dehumidifier 1000 is controlled by the electrical control board. Compared with conventional products in which the electrical control component is mounted on the water receiving tray, in the above configuration of the dehumidifier 1000 of the present application, the electrical control box 700 is away from the lower part of the evaporator where condensed water drips and the water tank assembly 200 for storing water, so as to prevent the condensed water from entering the electrical control box 700 to wet and damage the electrical control box 700, thereby achieving separation of water and electricity. In addition, the electrical control box 700 and the compressor 100 are both located in an independent space on a lateral side of the water tank assembly 200, the evaporator, and the condenser. Such an arrangement is conducive to heat dissipation of the electrical control box 700, thereby improving the operating performance of the electrical control box 700. It should be noted that the electrical control box 700 is located right above the compressor 100.
Referring to FIG. 1 and FIG. 3, in an embodiment, the electrical control box 700 is arranged close to a top of the housing 500. It can be understood that in the above configuration, there is a large gap between the electrical control box 700 and the compressor 100, which provides a more excellent heat dissipation effect for the electrical control box 700 and the compressor 100. In addition, if the electrical control box 700 and the compressor 100 are faulty, maintenance personnel can conveniently repair them through the large spacing. Referring to FIG. 1 and FIG. 2, in an embodiment, a top end of the electrical control box 700, a top end of the evaporator, and the top end of the condenser are vertically flush with each other. In this case, the electrical control box 700 may be mounted on the heat exchange assembly 300, thus facilitating the mounting of the electrical control box 700.
Referring to FIG. 3, according to an embodiment of the present application, the dehumidifier 1000 further includes a capacitor 110 electrically connected to the compressor 100, so that a larger starting torque can be obtained when the compressor 100 is started. In addition, the capacitor 110 is mounted between the air duct assembly 400 and the electrical control box 700, so that the capacitor 110 does not occupy the mounting space of the compressor 100, and the overall structural layout of the dehumidifier 1000 is reasonable.
Referring to FIG. 6, in the dehumidifier 1000 according to the embodiment of the present application, the mounting structure 210 is formed with an inner cavity 211, and the mounting structure 210 further has a mounting opening 212 at an end of the mounting structure 210 facing away from the compressor 100 and communicates with the inner cavity 211. In addition, a bottom wall of the inner cavity 211 has a first notch 2111 located at an end of the bottom wall of the inner cavity 211 close to the mounting opening 212. It should be noted that a lower end of the water tank 220 has a catch groove 2201 exposed through the first notch 2111. It can be understood that a user can directly reach an underside of the housing 500 to grasp the catch groove 2201 through the first notch 2111, and pull the water tank 220 out. In the above configuration, no additional space needs to be provided for a user's hand to grasp the catch groove 2201, so the catch groove 2201 has little impact on the volume of the water tank 220 and the dehumidifier 1000 has an aesthetic appearance. It should be noted that the size and shape of the first notch 2111 are not particularly limited herein, and the size and shape of the catch groove 2201 are not particularly limited herein.
Referring to FIG. 3 and FIG. 6, in an embodiment, the first direction is a length direction of the dehumidifier 1000, and the mounting opening 212 is provided at an end of the inner cavity 211 in the length direction of the dehumidifier 1000. In the above configuration, the water tank 220 is mounted to the mounting structure 210 from a lateral side, so the water tank 220 has a greater length and a larger volume as compared with the related product.
Referring to FIG. 1 and FIG. 6, it should be noted that the water tank 220 includes a tank body 221, and the tank body 221 includes a bottom plate 2211, a top plate 2213, and a plurality of side plates 2212. The plurality of side plates 2212 are arranged along a periphery of the bottom plate 2211. The plurality of side plates 2212 are also arranged along a periphery of the top plate 2213. The bottom plate 2211 is connected to a bottom end of each of the plurality of side plates 2212. The top plate 2213 is connected to a top end of each of the plurality of side plates 2212. The catch groove 2201 is provided on the bottom plate 2211. A second notch 2202 is provided on the side plate 2212 on a side of the water tank 220 away from the compressor 100. The second notch 2202 is in communication with the catch groove 2201. It can be understood that the arrangement of the second notch 2202 makes it more convenient for a user to grasp the catch groove 2201. It should be noted that the size and shape of the second notch 2202 are not particularly limited herein.
Referring to FIG. 6, the mounting structure 210 has a first limit rib 213 extending in a direction away from the compressor 100. In addition, the first limit rib 213 is located on a top wall of the inner cavity 211 and abuts against a top end of the water tank 220. It should be noted that the first limit rib 213 and the mounting structure 210 are integrally formed. During the user takes out the water tank 220, the first limit rib 213 can limit the water tank 220 to prevent the water tank 220 from falling to ground. Still referring to FIG. 6, in an embodiment, an end of the first limit rib 213 is connected to an end of the mounting structure 210 close to the compressor 100. The length of the first limit rib 213 is defined as a, the length of the inner cavity 211 in a direction away from the compressor 100 is defined as b, and a ≤ b is satisfied. It should be noted that when a = b, the water tank 220 abuts against the first limit rib 213 all the time during the user takes out the water tank 220, until the water tank 220 is completely taken out; and when a < b, there is a segment of stroke where the water tank 220 no longer abuts against the first limit rib 213 during the user takes out the water tank 220, in which case the user can take out the water tank 220 upward. In an embodiment, there are a plurality of first limit ribs 213 arranged at intervals in the second direction. In an embodiment, the second direction is a width direction of the dehumidifier 1000. The plurality of first limit ribs 213 are arranged at equal intervals in the second direction. In the above configuration, the limiting effect of the first limit ribs 213 on the water tank 220 is enhanced.
Referring to FIG. 3 and FIG. 6, according to an embodiment of the present application, the dehumidifier 1000 further includes a base plate 600 above which the compressor 100 and the mounting structure 210 are both mounted, i.e., the base plate 600 supports the compressor 100 and the mounting structure 210. It should be noted that the base plate 600 and the mounting structure 210 jointly define the inner cavity 211, and the bottom wall of the inner cavity 211 is the base plate 600, so the first notch 2111 is located at an end of the base plate 600 close to the mounting opening 212. In an embodiment, the base plate 600 has a second groove 610, and a lower end surface of the water tank 220 abuts against the second groove 610. In the above configuration, the water tank 220 can be configured to be large, thereby increasing the water storage capacity of the water tank 220.
Referring to FIG. 6 and FIG. 7, in the dehumidifier 1000 according to the embodiment of the present application, a handle 223 is rotatably connected to an upper end of the water tank 220, and the handle 223 is configured to be rotated to an underside of the upper end surface of the water tank 220. In the above configuration, when the water tank 220 is mounted in the inner cavity 211, the handle 223 is located below the upper end surface of the water tank 220. As such, a space required for mounting the water tank 220 is not increased, and the overall structure of the water tank assembly 200 is compact. It can be understood that after a user pulls the water tank 220 through the catch groove 2201 to cause the water tank 220 to translate for a distance, the handle 223 is exposed. In this case, the user can rotate and grasp the handle 223, pull and lift the water tank 220 through the handle 223. As such, user experience is improved.
Referring to FIG. 7, in the dehumidifier 1000 according to the embodiment of the present application, the water tank 220 further includes a float 222 with a rotation shaft 2221, and the float 222 is connected to the tank body 221 through the rotation shaft 2221. It should be noted that the float 222 is configured to test the water level in the water tank 220. When the water level rises, the float 222 rotates upward about the rotation shaft 2221. When the water level falls, the float 222 rotates downward about the rotation shaft 2221. Referring to FIG. 7 and FIG. 8, in an embodiment, the tank body 221 has a second limit rib 2214, and the rotation shaft 2221 has a limit member 2203. The limit member 2203 is located on one side of the second limit rib 2214, and is configured to abut against the second limit rib 2214 to limit an angle of rotation of the float 222 about the rotation shaft 2221. During the assembly process of mounting the float 222 on the tank body 221, since there is no water in the tank body 221 at this moment, the mounted float 222 rotates downward about the rotation shaft 2221. Referring to FIG. 9 and FIG. 10, in this case, after the float 222 rotates downward by an angle, the limit member 2203 abuts against the second limit rib 2214 to prevent the float 222 from continuing to rotate downward, thereby preventing failure of the float 222 during use due to undue falling during mounting.
Referring to FIG. 8, in an embodiment, the limit member 2203 includes a first bent plate 2204 and a second bent plate 2205. The first bent plate 2204 is connected to one end of the rotation shaft 2221, and the second bent plate 2205 is rotatably connected to the tank body 221. It should be noted that the first bent plate 2204 and the second bent plate 2205 are integral formed. In an embodiment, an angle between the first bent plate 2204 and the second bent plate 2205 is 90 degrees.
According to the dehumidifier of the embodiments of the present application, the mounting structure is located on one side of the compressor in the first direction of the dehumidifier, and the heat exchange assembly is arranged above the mounting structure. The air duct assembly is arranged side by side with the heat exchange assembly in the second direction of the dehumidifier and is located above the mounting structure. Further, the mounting structure is formed with the inner cavity, the mounting opening in communication with the inner cavity is provided at the end of the mounting structure facing away from the compressor, and the water tank is detachably arranged in the inner cavity through the mounting opening. The water tank, the mounting structure, the air duct assembly, and the heat exchange assembly are located in an independent space on one side, and the compressor is located in an independent space on the other side. Such a skillful design of the internal structure of the dehumidifier reduces the overall height and therefore the volume and weight of the dehumidifier, making it convenient for a user to use and store. In addition, because the first notch is provided at the end of the bottom wall of the inner cavity close to the mounting opening, and the catch groove at the lower end of the water tank is exposed through the first notch, no additional space needs to be provided for the user to grasp the catch groove. Therefore, the catch groove has little impact on the volume of the water tank, and the dehumidifier has an aesthetic appearance.
