Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a dehumidifier. Background Art

[0002] A humid environment is not conducive to people's activities, nor to the storage and use of equipment and instruments. A dehumidifier can play a role in drying the air, enabling people or equipment to work in a suitable humidity environment. Existing dehumidifiers generally include an evaporator and a condenser, which form a refrigeration cycle system. When working, the evaporator obtains an evaporation temperature lower than the dew point of the ambient air. When air passes through the evaporator, once the air temperature drops below the dew point temperature, the moisture in the air will condense out. Then, the low-temperature and low-humidity air condensed by the evaporator passes through the condenser. The condenser heats the air with the high-temperature and high-pressure refrigerant gas inside and then transports it to the indoor environment to avoid the impact of low-temperature air on the environment.

[0003] Currently, most dehumidifiers on the market use one evaporator and one condenser, and have single-sided air inlet and single-sided air outlet, resulting in poor dehumidification effect and low overall working performance of the dehumidifier. Summary of the Invention

[0004] The main object of the present invention is to provide a dehumidifier, aiming to achieve good dehumidification effect and high working performance of the dehumidifier.

[0005] To achieve the above object, the dehumidifier proposed by the present invention includes:

[0006] A housing, which is provided with a first air inlet, a second air inlet and an air outlet, and forms an air duct communicating the first air inlet, the second air inlet and the air outlet;

[0007] A first dehumidification component, which is arranged in the air duct, is inclined with respect to the bottom surface of the housing, and corresponds to the first air inlet;

[0008] A second dehumidification component, which is arranged in the air duct, is inclined with respect to the bottom surface of the housing, and corresponds to the second air inlet; and

[0009] A blower, which is arranged in the air duct, is located above the first dehumidification component and the second dehumidification component, and is adjacent to the air outlet, and introduces air into the air duct from the first air inlet and the second air inlet;

[0010] The air entering from the first air inlet is blown out from the air outlet after passing through the first dehumidification component, and the air entering from the second air inlet is blown out from the air outlet after passing through the second dehumidification component.

[0011] Preferably, the blower includes a volute and an impeller disposed within the volute. The volute has an air inlet side and an air outlet side. The air inlet side corresponds to the first dehumidification component and the second dehumidification component, and the air outlet side corresponds to the air outlet.

[0012] Preferably, the blower is a cross-flow blower.

[0013] Preferably, a water receiving tray and a water storage tank are further disposed within the housing. The water receiving tray is disposed below the dehumidification component and is provided with a drain opening communicating with the water storage tank.

[0014] Preferably, one end of the first dehumidification component is adjacent to one end of the second dehumidification component. The first dehumidification component gradually moves away from the bottom surface of the housing from this end to the other end, and the second dehumidification component gradually moves away from the bottom surface of the housing from this end to the other end.

[0015] Preferably, the housing is further provided with a third opening communicating with the air duct. A third dehumidification component is further disposed within the air duct. The third dehumidification component corresponds to the third opening and is adjacent to the first dehumidification component or the second dehumidification component.

[0016] Preferably, the first dehumidification component, the second dehumidification component, and the third dehumidification component each include an evaporator and a condenser stacked along the air inlet direction.

[0017] Preferably, the dehumidifier further includes a compressor. The evaporators and condensers of the first dehumidification component, the second dehumidification component, and the third dehumidification component are connected in parallel by pipelines and then connected in series to the compressor to form a refrigerant circuit. A throttling component is provided between each group of evaporators and condensers.

[0018] Preferably, both the evaporator and the condenser are in a plate shape.

[0019] Preferably, the evaporators of the first dehumidification component, the second dehumidification component, and the third dehumidification component are of an integrally formed structure, and the condensers of the first dehumidification component, the second dehumidification component, and the third dehumidification component are of an integrally formed structure.

[0020] In the technical solution of the present invention, the housing is provided with a first air inlet, a second air inlet, and an air outlet, and an air duct is formed that communicates the first air inlet, the second air inlet, and the air outlet. The first dehumidification component corresponds to the first air inlet. The air entering the air duct from the first air inlet is dehumidified by the first dehumidification component to form dry air, which is blown out from the air outlet. The second dehumidification component corresponds to the second air inlet. The air entering the air duct from the second air inlet is dehumidified by the second dehumidification component to form dry air, which is blown out from the air outlet. The dehumidifier has two air inlets and two dehumidification components, and can dehumidify the air entering from the two air inlets respectively, which is equivalent to increasing the dehumidification area of the dehumidifier and improving the dehumidification effect of the dehumidifier.

[0021] Further, since both the first dehumidification component and the second dehumidification component are inclined with respect to the bottom surface of the housing, while increasing the dehumidification area, the overall height of the machine is relatively low and the occupied space is small.

[0035] Please refer to Figures 1 to 4 , the present invention provides a dehumidifier 100, and the dehumidifier 100 includes:

[0036] A housing (not shown), the housing is provided with a first air inlet, a second air inlet and an air outlet, and a duct communicating the first air inlet, the second air inlet and the air outlet is formed;

[0037] A first dehumidification component 11, the first dehumidification component 11 is disposed in the duct, is inclined with respect to the bottom surface of the housing, and corresponds to the first air inlet;

[0038] A second dehumidification component 13, the second dehumidification component 13 is disposed in the duct, is inclined with respect to the bottom surface of the housing, and corresponds to the second air inlet; and

[0039] A fan 30, the fan 30 is disposed in the duct, is located above the first dehumidification component 11 and the second dehumidification component 13, and is adjacent to the air outlet, and introduces air into the duct from the first air inlet and the second air inlet;

[0040] The air entering from the first air inlet is blown out from the air outlet after passing through the first dehumidification component 11, and the air entering from the second air inlet is blown out from the air outlet after passing through the second dehumidification component 13.

[0041] In the technical solution of the present invention, the housing is provided with a first air inlet, a second air inlet and an air outlet, and a air duct communicating the first air inlet, the second air inlet and the air outlet is formed. The first dehumidification component 11 is arranged corresponding to the first air inlet. The air entering the air duct from the first air inlet is dehumidified by the first dehumidification component 11 to form dry air and is blown out from the air outlet. The second dehumidification component 13 is arranged corresponding to the second air inlet. The air entering the air duct from the second air inlet is dehumidified by the second dehumidification component 13 to form dry air and is blown out from the air outlet. The dehumidifier 100 has two air inlets and two dehumidification components, and can dehumidify the air entering from the two air inlets respectively, which is equivalent to increasing the dehumidification area of the dehumidifier 100 and improving the dehumidification effect of the dehumidifier 100.

[0042] Further, since both the first dehumidification component 11 and the second dehumidification component 13 are inclined with respect to the bottom surface of the housing, while increasing the dehumidification area, the overall height of the machine is relatively low and the occupied space is small.

[0043] In an embodiment of the present invention, the first air inlet and the second air inlet are inclinedly arranged on two side surfaces of the housing, and an included angle is formed between the first air inlet and the second air inlet, so that the air inlet area of the dehumidifier 100 is increased, and the first dehumidification component 11 and the second dehumidification component 13 are arranged corresponding to the first air inlet and the second air inlet respectively, thereby increasing the dehumidification and heat exchange area of the dehumidifier 100.

[0044] In an embodiment of the present invention, the fan 30 includes a volute 31 and an impeller 33 arranged in the volute 31. The volute 31 has an air inlet side 311 and an air outlet side 313. The air inlet side 311 corresponds to the first dehumidification component 11 and the second dehumidification component 13, and the air outlet side 313 corresponds to the air outlet.

[0045] The impeller 33 rotates in the volute 31. The fan 30 sucks the air from the air inlet side 311 and discharges it from the air outlet side 313.

[0046] See Figure 1 , in an embodiment of the present invention, the fan 30 is a cross-flow fan. The cross-flow fan has a large air volume and low noise, so that the dehumidifier 100 has a large air inlet volume and relatively small noise during operation.

[0047] The length directions of the cross-flow fan, the first dehumidification component and the second dehumidification component are the same, so that under the drive of the fan 30, the air inlet and air outlet effects of the dehumidifier 100 are more uniform.

[0048] In an embodiment of the present invention, a water receiving tray and a water storage tank are further provided inside the housing. The water receiving tray is disposed below the first dehumidifying component 11 and the second dehumidifying component 13, and is provided with a drain opening communicating with the water storage tank. Since during the process of heat exchange between the air and the first dehumidifying component 11 and the second dehumidifying component 13, condensed water is generated on the first dehumidifying component 11 and the second dehumidifying component 13. The condensed water flows downward along the first dehumidifying component 11 and the second dehumidifying component 13 to the water receiving tray, and then enters the water storage tank through the drain opening. The user can take out the water storage tank to pour out the accumulated condensed water.

[0049] The water receiving tray is inclined, and the drain opening is located at the lowest position of the water receiving tray, facilitating the water received on the water receiving tray to be completely drained from the drain opening to the water storage tank without water accumulation at the water receiving tray, so that bacteria are not easily generated inside the dehumidifier 100, and the dehumidifying process is healthy and environmentally friendly.

[0050] See Figure 3 , in an embodiment of the present invention, one end of the first dehumidifying component 11 is adjacent to one end of the second dehumidifying component 13. The first dehumidifying component 11 gradually moves away from the bottom surface of the housing from this end to the other end, and the second dehumidifying component 13 gradually moves away from the bottom surface of the housing from this end to its other end.

[0051] The two side surfaces of the housing extend to the bottom surface to form a first air inlet and a second air inlet. Both the first dehumidifying component 11 and the second dehumidifying component 13 form an angle with the bottom surface of the housing and are adjacent at one end, making full use of the internal space of the housing and resulting in a smaller overall height of the machine.

[0052] In an embodiment of the present invention, the housing is further provided with a third opening communicating with the air duct, and a third dehumidifying member 15 is further provided inside the air duct. The third dehumidifying component 15 is disposed corresponding to the third opening, and the third dehumidifying component 15 is adjacent to the first dehumidifying component 11 or the second dehumidifying component 13.

[0053] Adding the third opening and the third dehumidifying component 15 makes the overall dehumidifying and heat exchange area of the dehumidifier 100 larger, the dehumidifying effect better, and the working performance of the dehumidifier 100 is further improved.

[0054] Since the fan 30 is a cross-flow fan, the air outlet side 313 deflects towards one side compared with the volute 31. The third dehumidifying component 15 is located in the direction away from the air outlet side 313 of the fan 15, and one end is adjacent to the second dehumidifying component 13, and the other end extends in the direction away from the bottom surface of the housing, making the suction force of the fan 30 at the third dehumidifying component 15 stronger, and capable of sucking air from the first air inlet, the second air inlet and the third air inlet respectively, and fully carrying out heat exchange with the first dehumidifying component 11, the second dehumidifying component 13 and the third dehumidifying component 15, so that the dehumidifying effect of the dehumidifier 100 is better.

[0055] In an embodiment of the present invention, the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 each include an evaporator 111 and a condenser 113 stacked along the air inlet direction.

[0056] The air entering the air duct from the first air inlet, the second air inlet, and the third air inlet first passes through the evaporator 111, and moisture condenses on the evaporator 111. Then, it passes through the condenser 113 for temperature recovery and is blown to the air outlet through the air outlet side 313 of the fan 30.

[0057] In an embodiment of the present invention, the dehumidifier 100 further includes a compressor (not shown). The evaporators 111 and condensers 113 of the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are connected in parallel by a refrigerant pipeline and then connected in series to the compressor to form a refrigerant circuit. A throttling component (not shown) is provided between each evaporator 111 and condenser 113.

[0058] The refrigerant is compressed into a high-temperature and high-pressure superheated gas in the compressor, enters the condenser 111, and releases heat on the condenser 111 to heat the air. After passing through the condenser 111, the refrigerant condenses into a subcooled liquid, forms a low-temperature and low-pressure liquid through the throttling component, enters the evaporator 113, and absorbs heat from the air on the evaporator 113, and so on in a cycle.

[0059] In an embodiment of the present invention, both the evaporator 111 and the condenser 113 are in a plate shape. The evaporator 111 and condenser 113 in a plate shape have a simple structure and a low production cost, making the overall cost of the dehumidifier 100 low.

[0060] See Figure 4 In an embodiment of the present invention, the evaporators 111 of the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are of an integrally formed structure, and the condensers 113 of the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are of an integrally formed structure.

[0061] That is, the evaporators 111 of the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are formed by bending an evaporator 111, and the condensers 113 of the first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are formed by bending a condenser 113. This makes the overall structure of the dehumidifier 100 simple and reduces the production and installation costs.

[0062] It can be understood that in the technical solution of the present invention, the number of dehumidification components can be not only two or three but also more, and they are all arranged around the air inlet side of the fan, making the heat exchange of the dehumidifier 100 more uniform, the dehumidification effect better, and further improving the overall performance of the machine.

[0063] The first dehumidification component 11, the second dehumidification component 13, and the third dehumidification component 15 are arranged adjacent to each other in sequence along the width direction. Since the blower 30 selected in the technical solution of the present invention is a cross-flow blower, the length direction of the cross-flow blower is consistent with the length direction of each dehumidification component, and the length of the cross-flow blower is equivalent to the length of each dehumidification component, which not only makes the internal space of the dehumidifier 100 more fully utilized, but also makes the air suction effect of the blower 30 better.

[0064] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present invention.
