Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifiers, and in particular to a dehumidifier capable of high-efficiency and intelligent dehumidification and defrosting. Background Art

[0002] A dehumidifier is composed of a compressor, a heat exchanger, a fan, a water tank, a shell and a controller. Its working principle is: the fan draws humid air into the machine, passes through the heat exchanger, and the moisture in the air condenses into water droplets. The treated dry air is discharged out of the machine. This cycle reduces the indoor humidity.

[0003] In the prior art, for example, a dehumidifier with an intelligent defrosting function is disclosed in Chinese Patent No. CN202382493U. The dehumidifier body also includes an air circulation system and a defrosting ventilation control device (8). The air circulation system includes a filter (9) and a centrifugal fan (10). The filter (9) is arranged at the air inlet of the dehumidifier. A temperature sensor I (11) and a humidity sensor (12) are arranged on the side of the air inlet located outdoors. A temperature sensor II (13) of the evaporator heat exchange tube is arranged on the heat exchange tube of the evaporator (4). The centrifugal fan (10) is located at the air outlet of the dehumidifier. The signal output end of the temperature sensor I (11), the signal output end of the humidity sensor (12) and the signal output end of the temperature sensor II (13) are all connected to the input end of the defrosting ventilation control device (8). The output end of the defrosting ventilation control device (8) is connected to the motor (6) of the centrifugal fan (10).

[0004] In the prior art, the surface of the evaporator of the dehumidifier is prone to frost when it is working. After the evaporator surface is frosted, the compressor will stop and the dehumidifier will enter the defrosting mode. Therefore, the dehumidifier can only be restarted after the frost on the surface of the evaporator is automatically removed, and the dehumidification efficiency is low. In the prior art, the above-mentioned heat-conducting components (heat-absorbing parts) or additional heating components are often used to physically defrost the evaporator (heat-conducting defrosting), which will increase the internal parts of the dehumidifier to a certain extent and increase the production cost of the dehumidifier. At the same time, such heat-conducting components (heat-absorbing parts) or additional heating components will increase the internal temperature of the dehumidifier to a certain extent, and the compressor will also generate a certain temperature when working. If the internal temperature of the dehumidifier is too high, the compressor will also trip, affecting the normal use of the dehumidifier. When the existing dehumidifier is working, the condenser itself will generate a certain amount of heat. If the heat generated by the condenser can be directly applied to the evaporator, the above-mentioned problem can be solved without increasing the production cost of the dehumidifier. The compressor can also be protected from heat dissipation to prevent the compressor from tripping due to high temperature. Summary of the invention

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Embodiment 1:

[0046] like Figure 1-11 As shown, a dehumidifier with high efficiency and intelligent dehumidification and defrosting comprises a shell 1, on which air vents 1 and 2 are provided, and the air vents 1 and 2 are located on the same horizontal plane;

[0047] A fan structure 3 is arranged at the first air outlet, and the wind direction of the fan structure 3 is adjustable, so that the air can flow from the first air outlet to the second air outlet, and the air can also flow from the second air outlet to the first air outlet;

[0048] A dehumidification mechanism is arranged at the second air outlet, and the dehumidification mechanism includes a condenser 4, an evaporator 5 and a compressor 8; the condenser 4 is located between the fan structure 3 and the evaporator 5; the compressor 8 is arranged below the fan structure 3, and the compressor 8 is connected to the condenser 4 and the evaporator 5 through pipelines respectively;

[0049] Among them, a refrigerant storage tank is also provided inside the shell 1 for storing refrigerant, so that the compressor 8 can compress the refrigerant and then deliver it to the condenser 4 and the evaporator 5 for use; the setting of the fan structure 3 can change the air inlet direction of the dehumidifier, so that the wind direction can present a 180° linear change between the air outlet one and the air outlet two (that is, the air can flow from the air outlet one to the air outlet two, or the air can flow from the air outlet two to the air outlet one); when the air flows from the air outlet two to the air outlet one, the ambient air outside the dehumidifier will preferentially contact the evaporator 5 and the condenser 4 of the dehumidification mechanism, and condense the moisture (water vapor) in the air through the evaporator 5 and the condenser 4, so that the air is guided to the air outlet one through the fan structure 3 after dehumidification, so as to realize the dehumidification of the air; because the condenser 4 will generate a certain amount of heat when working, when the air flows from the air outlet two to the air outlet one, the heat will be taken out to realize the heat dissipation of the dehumidification mechanism; and when the air flows from the air outlet one to the air outlet two, the flowing air will condense the condenser 4 The heat generated during operation is directly blown to the evaporator 5, and the heat of the condenser 4 is used to physically melt the frost condensed on the surface of the evaporator 5, thereby avoiding the situation where the compressor 8 stops working due to the frost on the evaporator 5, ensuring the stable operation of the dehumidifier, and further ensuring the dehumidification efficiency of the dehumidifier; at the same time, the fan structure 3 will also generate a certain amount of heat during operation, so when the air flows from the first air outlet to the second air outlet, the heat generated by the fan structure 3 and the heat generated by the condenser 4 act on the surface of the evaporator 5, which can accelerate the defrosting rate of the evaporator 5; at the same time, due to the wind force of the fan structure 3, the heat inside the dehumidifier (the heat generated by the condenser 4 and the heat generated by the compressor 8) will also be discharged from the second air outlet, and the heat dissipation effect of blowing heat is much higher than that of suction heat dissipation, so the dehumidifier can be quickly cooled down, which realizes the heat dissipation of the compressor on the one hand, avoids the compressor overheating tripping, and prolongs the service life of the compressor, and on the other hand, shortens the heat dissipation time of the dehumidifier, thereby improving the working efficiency of the dehumidifier;

[0050] In this embodiment, the fan structure 3 includes an air guide cover 31, a protective cover 32, a main board 33 and a fan body; the fan body is detachably connected between the protective cover 32 and the main board 33; the air guide cover 31 is sleeved on the outer sides of the protective cover 32, the main board 33 and the fan body, and one end of the air guide cover 31 is connected to the protective cover 32; the fan body is composed of more than 5 blades 34 extending in the same direction and arranged at intervals, and the number of the blades 34 is preferably 6; the main board 33 is provided with more than 4 holes 332 arranged at intervals, and the number of the holes 332 is preferably 6; a motor 35 with adjustable steering is provided in the center of the outer side of the main board 33, and the output shaft of the motor 35 passes through the center of the main board 33 and is connected to the main board 33;

[0051] The fan blade 34 is an arc-shaped blade with a quadrilateral structure, which is named counterclockwise as the first side 341, the second side 342, the third side 343 and the fourth side 344; the first side 341 is an inner concave arc side, and the first side 341 is provided with a first protrusion 3411 for connecting to the shield 32; the second side 342 close to the third side 343 is higher than the second side 342 close to the first side 341; the third side 343 is provided with a second protrusion 3431 for connecting to the main board 33; the fourth side 344 is an outer convex arc side; after the fan blade 34 is connected to the shield 32 and the main board 33, the first side 341 is located on the inner side of the shield 32 and the main board 33, the fourth side 344 is located on the outer side of the shield 32 and the main board 33 and extends to the inner wall of the wind guide cover 31, and the inner concave side wall of the fan blade 34 forms an angle a with the outer edge of the circumference, and the angle a is 28-33°;

[0052] Among them, when the motor 35 of the fan structure 3 rotates forward, the main board 33, the fan body and the shield 32 rotate forward, and the air will enter the shell 1 from the second air outlet, and enter the wind guide cover 31 from one end of the motor 35 after being dehumidified by the dehumidification mechanism. At this time, the air passes through the holes 332 on the main board 33 and the gaps between the fan blades 34, passes through the shield 32 and is guided to the air outlet one by the wind guide cover 31 at one end of the shield 32; and when the motor 35 of the fan structure 3 rotates reversely, the main board 33, the fan body and the shield 32 rotate reversely, and the air will enter the shell 1 from the first air outlet, and preferentially pass through the fan structure 3 and then blow to the dehumidification mechanism. At this time, the air enters the shield 32 from the wind guide cover 31 at one end of the shield 32, and flows to the wind guide cover 31 at one end of the motor 35 through the gaps between the fan blades 34 and the holes 332 on the main board 33, and blows to the dehumidification mechanism; due to the influence of the wind guide cover 3 1 and the structure of the fan blades 34, when the air flows at the fan structure 3, the wind resistance can be effectively reduced through the wind guide cover 31, the air supply volume can be increased, and the wind noise can be reduced. When the motor 35 rotates in the forward direction, the fan blades 34 with special shapes can quickly draw air from the holes 332 of the main board 33 and the gaps of the fan blades 34 to the shield 32 (that is, the air is synchronously introduced through the holes 332 and the gaps of the fan blades 34), so that the air can be quickly discharged from the wind guide cover 31 at one end of the shield 32, and when the motor 35 rotates in the reverse direction, the fan blades 34 can introduce air from the wind guide cover 31 at one end of the shield 32, so that part of the air passes through the gaps of the fan blades 34 and flows to the wind guide cover 31 at one end of the motor 35, and the other part of the air flows from the holes 332 of the main board 33 to the wind guide cover 31 at one end of the motor 35, so that the fan can still quickly discharge air after reversing, thereby comprehensively improving the air supply effect of the fan structure 3;

[0053] In a specific implementation of this embodiment, the housing 1 is further provided with a control module 2, which is electrically connected to the fan structure 3 and the dehumidification mechanism, and is used to control the opening and closing and the turning direction of the fan structure 3 and control the operation of the dehumidification mechanism;

The fan structure 3 and the dehumidification mechanism are protected by the shell 1, and the fixed assembly and later maintenance between the fan structure 3 and the dehumidification mechanism and the shell 1 are convenient, and the overall aesthetics of the dehumidifier is ensured; in this embodiment, the panel 14 is further provided with a filter screen 6 on the side close to the evaporator 5, which is used to filter the air entering the dehumidifier to prevent impurities in the air from adhering to the condenser 4 and evaporator 5 of the dehumidification mechanism, thereby ensuring the cleanliness of the air after dehumidification.

[0055] In a specific implementation of this embodiment, the dehumidifier further includes a water tank 7, which is movably arranged in the frame 11 below the condenser 4 and the evaporator 5, and is used to collect water condensed by the condenser 4 and the evaporator 5; wherein the arrangement of the water tank 7 can facilitate the collection of condensed water droplets generated by the condenser 4 and the evaporator 5, and the movably arranged water tank 7 can be conveniently separated from the housing 1, which is conducive to the cleaning of the condensed water stored in the water tank 7; in order to improve the tightness of the assembly of the water tank 7 and the frame 11, at least one pair of buckles 112 is provided on the frame 11, and a card groove (not marked in the figure) matching the buckle 112 is provided on the outer surface of the water tank 7, so that when the water tank 7 is installed in the frame 11, the buckle 112 and the card groove can cooperate with each other to stably fix the water tank 7 in the frame 11;

[0056] In order to ensure that the compressor 8 will automatically trip and stop when it is in a high temperature state, in this embodiment, a temperature sensor (not shown in the figure) is also installed at the exhaust port of the compressor 8 to sense the working temperature of the compressor 8; wherein the set temperature of the temperature sensor is lower than the trip temperature of the compressor 8; when the temperature of the evaporator 5 is higher than the set temperature, the motor 35 of the fan structure 3 is in a forward rotation state (i.e., the air will flow from the second air outlet to the first air outlet to achieve dehumidification and air suction and heat dissipation of the dehumidifier); when the temperature of the evaporator 5 is lower than the set temperature, the motor 35 of the fan structure 3 is in a reverse rotation state (i.e., the air will flow from the first air outlet to the second air outlet to achieve defrosting and air blowing and heat dissipation of the dehumidifier). Through the reversing blowing of the fan structure 3, the air blowing and heat dissipation efficiency of the fan structure 3 can be made much higher than the traditional air suction and heat dissipation efficiency, which can not only achieve rapid cooling of the dehumidifier, shorten the heat dissipation time, and improve the dehumidification efficiency, but also protect the compressor 8 and reduce the damage of the compressor 8.
