A new type of dehumidifier

Abstract

The present invention provides a new dehumidifier, which is provided with a first heat exchange chamber for accommodating an evaporator and a condenser, a second heat exchange chamber for accommodating a compressor, an air supply chamber for accommodating a fan, and a heat dissipation channel connecting the second heat exchange chamber and the air supply chamber inside the casing assembly. The first heat exchange chamber, the second heat exchange chamber and the air supply chamber are connected in series to form an air duct loop for external circulation of air. Under the action of the fan, the indoor air is transported to the air outlet through the air inlet, the first heat exchange chamber, the second heat exchange chamber and the air supply chamber in sequence. The air in the first heat exchange chamber that has been dehumidified and dried can be air-cooled and dissipated to the compressor when it flows through the second heat exchange chamber, thereby avoiding the dehumidifier from being unable to work normally due to excessive exhaust pressure and exhaust temperature when the compressor is working in a high-temperature environment. At the same time, the heat generated by the compressor can heat the air again to further reduce the relative humidity in the air and improve the dehumidification efficiency and dehumidification effect.

Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning equipment, and in particular, relates to a novel dehumidifier. Background Art

[0002] A dehumidifier is an air handling device used to regulate air humidity. Its main working principle is to draw the humid air in the room into the casing through a fan. The humid air first passes through the evaporator for heat exchange and dehumidification, and then passes through the condenser to heat up and become high-temperature dry air. The high-temperature dry air is sent into the room through the fan, thereby achieving the effect of reducing the humidity in the indoor space.

[0003] At present, the compressor of a dehumidifier is generally arranged in a confined space inside the casing. Due to the poor air circulation in the confined space inside the casing and the large amount of heat generated when the compressor is working, when the compressor is in a harsh environment with too high ambient temperature (ambient temperature greater than 40°C), it is easy to have problems with poor heat dissipation or untimely heat dissipation, resulting in excessively high exhaust pressure and exhaust temperature of the compressor, causing the compressor to be unable to compress the refrigerant stably and normally, thereby limiting the use of dehumidifiers in harsh environments with high temperatures (temperature greater than 40°C).

[0047] Please also read Figures 1 to 7 Now, a novel dehumidifier provided by an embodiment of the present invention is described. Figure 1 , Figure 2 and Figure 4A novel dehumidifier provided in an embodiment of the present invention includes a housing assembly 1, an evaporator 2, a condenser 3, a compressor 4 and a fan 5. The housing assembly 1 is provided with an air inlet 11 for introducing indoor air and an air outlet 12 for discharging dehumidified air into the room. The air inlet 11 is a mesh-type air outlet or a grille-type air outlet. The housing assembly 1 is provided with a first heat exchange chamber 13 for accommodating the evaporator 2 and the condenser 3, a second heat exchange chamber 14 for accommodating the compressor 4, an air supply chamber 15 for accommodating the fan 5, and a heat dissipation channel connecting the second heat exchange chamber 14 and the air supply chamber 15. The air inlet 11 is connected with the first heat exchange chamber 13, the first heat exchange chamber 13 is connected with the second heat exchange chamber 14, the second heat exchange chamber 14 is connected with the air outlet 12, and the first heat exchange chamber 13, the second heat exchange chamber 14 and the air supply chamber 15 are connected in series to form an air duct loop for external circulation of air. The evaporator 2 is arranged in the first heat exchange chamber 13, and is used to evaporate the liquid refrigerant to form a gaseous refrigerant, and absorb the heat in the air to reduce the temperature of the air, so that the moisture in the air is adsorbed on the aluminum foil of the evaporator 2 to reduce the absolute humidity in the air. The condenser 3 is arranged in the first heat exchange chamber 13, and is used to condense the gaseous refrigerant to form a liquid refrigerant, and heat the air treated by the evaporator 2 to reduce the relative humidity in the air. The compressor 4 is arranged in the second heat exchange chamber 14, and is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant to provide power for the internal circulation of the refrigerant in the loop formed by the evaporator 2, the compressor 4 and the condenser 3 in series. The fan 5 is arranged in the air supply chamber 15 and is close to the air outlet 12. The fan 5 is used to transport the indoor air to the air outlet 12 through the air inlet 11, and provides power for the external circulation of the indoor air in the air duct loop formed by the first heat exchange chamber 13, the second heat exchange chamber 14 and the air supply chamber 15 in series. It should be noted that the fan 5 in this embodiment can be but not limited to a centrifugal fan. For example, the fan 5 in other embodiments can also be an axial flow fan or a cross-flow fan or other types of fans. In addition, in the dehumidifier, the dehumidifier internal circulation working principle constructed by the evaporator 2, the condenser 3 and the compressor 4 is a mature existing technology and will not be elaborated here.

[0048] When a new dehumidifier provided by an embodiment of the present invention is in dehumidification operation, that is, when the dehumidifier constructed by the evaporator 2, the condenser 3 and the fan 5 performs external circulation operation, under the action of the fan 5, the indoor air is sequentially transported to the air outlet 12 through the air inlet 11, the first heat exchange chamber 13, the second heat exchange chamber 14 and the air supply chamber 15, and the air discharged to the room through the air outlet 12 is dehumidified and dried air, and the temperature of the dehumidified and dried air is slightly higher than the room temperature. In this way, the circulation operation is carried out to achieve the effect of dehumidifying the room. Specifically, when the air flows through the first heat exchange chamber 13, the evaporator 2 absorbs the heat in the air to reduce the temperature of the air, so that the moisture in the air is adsorbed on the aluminum foil of the evaporator 2, and the moisture in the air is removed to reduce the absolute humidity in the air, that is, the humid air can be converted into low-temperature dry air. The low-temperature dry air is heated and heated by the condenser 3 to reduce the relative humidity in the air and obtain dehumidified and dried air. Then, the temperature of the air in the first heat exchange chamber 13 after being dehumidified and dried by the evaporator 2 and the condenser 3 is lower than the temperature of the compressor 4 surface or the air in the second heat exchange chamber 14. In the process of flowing through the second heat exchange chamber 14, the air can be cooled and dissipated by the compressor 4, and the heat generated by the compressor 4 when working can be taken away in time and smoothly, effectively reducing the temperature of the compressor 4, and the temperature and pressure of the gaseous refrigerant circulating inside the compressor 4 can be reduced, thereby avoiding the dehumidifier from being unable to work normally due to excessive exhaust pressure and exhaust temperature when the compressor 4 works in a high temperature environment (temperature greater than 40°C). At the same time, the heat generated by the compressor 4 can be used to heat up the dehumidified air in the second heat exchange chamber 14 again, and the heat generated by the compressor 4 can be used to further reduce the relative humidity in the air, thereby helping to improve the dehumidification efficiency and dehumidification effect of the dehumidifier.

[0049] Compared with the prior art, the novel dehumidifier provided by the embodiment of the present invention is provided with a first heat exchange chamber 13 for accommodating the evaporator 2 and the condenser 3, a second heat exchange chamber 14 for accommodating the compressor 4, an air supply chamber 15 for accommodating the fan 5, and a heat dissipation channel connecting the second heat exchange chamber 14 and the air supply chamber 15 inside the housing assembly 1, and the first heat exchange chamber 13, the second heat exchange chamber 14 and the air supply chamber 15 are connected in series to form an air duct loop for external circulation of air. Under the action of the fan 5, the indoor air is transported to the air outlet 12 through the air inlet 11, the first heat exchange chamber 13, the second heat exchange chamber 14 and the air supply chamber 15 in sequence. The air in the first heat exchange chamber 13 that has been dehumidified and dried by the evaporator 2 and the condenser 3 can be air-cooled and dissipated to the compressor 4 in the process of flowing through the second heat exchange chamber 14, and can promptly and smoothly take away the heat generated by the compressor 4 when it is working, effectively reduce the temperature of the compressor 4, and avoid the dehumidifier from being unable to work normally due to excessive exhaust pressure and exhaust temperature when the compressor 4 is working in a high temperature environment. At the same time, the heat generated by the compressor 4 can be used to heat the dehumidified air again, and the heat generated by the compressor 4 can be used to further reduce the relative humidity in the air, which is beneficial to improving the dehumidification efficiency and dehumidification effect of the dehumidifier.

[0050] Please refer to Figure 1 In some embodiments, the heat dissipation channel is composed of a plurality of heat dissipation holes 16, and the plurality of heat dissipation holes 16 are arranged at the top of the second heat exchange cavity 14. In this embodiment, by arranging a plurality of heat dissipation holes 16 at the top of the second heat exchange cavity 14, a heat dissipation channel connecting the second heat exchange cavity 14 and the air supply cavity 15 is formed by the plurality of heat dissipation holes 16, and the residence time of the air in the second heat exchange cavity 14 can be prolonged, so that the heat in the second heat exchange cavity 14 can heat up the dehumidified air again.

[0051] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the fan 5 is located above the second heat exchange chamber 14, the air supply chamber 15 is arranged between the first heat exchange chamber 13 and the second heat exchange chamber 14, and a plurality of heat dissipation holes 16 are arranged at the top of the second heat exchange chamber 14. Under the negative pressure generated by the top fan 5, the hot air at the top of the second heat exchange chamber 14 can enter the air supply chamber 15 through the plurality of heat dissipation holes 16 in a timely and smooth manner, thereby being able to promptly and smoothly take away the heat generated by the compressor 4 when it is working, effectively reducing the temperature of the compressor 4, and avoiding the dehumidifier from being unable to work normally due to excessive exhaust pressure and exhaust temperature when the compressor 4 is working in a high temperature environment. It should be noted that in this embodiment, the fan 5 can be, but is not limited to, a centrifugal fan.

[0052] Please refer to Figure 3 , Figure 4 and Figure 7In some of the embodiments, the fan 5 is disposed at the top of the air supply cavity 15 , and the air outlet 12 is located at the side of the housing assembly 1 , which is conducive to the fan 5 transporting the dehumidified and dried air to various spaces in the room through the air outlet 12 .

[0053] Please refer to Figure 1 , Figure 2 and Figure 6 In some of the embodiments, the evaporator 2 and the condenser 3 are both U-shaped or C-shaped. The evaporator 2 and the condenser 3 are closely stacked and arranged, which can optimize the overall layout of the dehumidifier, making the overall structure of the dehumidifier more compact, which is conducive to the miniaturization of the dehumidifier.

[0054] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the evaporator 2 and the condenser 3 are both U-shaped or C-shaped. The evaporator 2 is located on the outside of the condenser 3, and the second heat exchange chamber 14 is located on the inside of the condenser 3. The inner wall of the condenser 3 constitutes one side wall of the air supply chamber 15, which is beneficial for the heat of the condenser 3 to be fully absorbed by the air in the air supply chamber 15.

[0055] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the evaporator 2 and the condenser 3 are both U-shaped or C-shaped, the air supply chamber 15 is located on the inner side of the condenser 3, and the air supply chamber 15 is separated between the first heat exchange chamber 13 and the second heat exchange chamber 14, so as to avoid the heat generated by the condenser 3 from being directly transferred or radiated to the air in the second heat exchange chamber 14, which is beneficial to reducing the temperature in the second heat exchange chamber 14, thereby avoiding the temperature in the second heat exchange chamber 14 being too high and affecting the normal operation of the compressor 4.

[0056] Please refer to Figure 1 , Figure 5 and Figure 7In some embodiments, a dry shoe chamber 6 and a dry shoe passage 7 connecting the dry shoe chamber 6 with the air supply chamber 15 are further provided inside the housing assembly 1, and a switch door 80 for opening or closing the inlet 30 of the dry shoe chamber 6, a damper 10 for opening or closing the air outlet 12, and a dry shoe valve 9 for opening or closing the dry shoe passage 7 are provided on the housing assembly 1. When the switch door 80 closes the inlet 30 of the dry shoe chamber 6 and the damper 10 is in an open state, the dry shoe valve 9 closes the dry shoe passage 7 under the negative pressure formed by the fan 5 in the air supply chamber 15, and the dehumidifier is in a dehumidification mode. When the switch door 80 opens the inlet 30 of the dry shoe chamber 6 and the air door 10 is in a closed state, the dry shoe valve 9 opens the dry shoe passage 7 under the action of the wind pressure formed by the fan 5 in the air supply chamber 15. At this time, the air supply chamber 15 is connected with the dry shoe chamber 6 through the dry shoe passage 7, and the fan 5 can blow dry air into the dry shoe passage 7 to dry the shoes in the dry shoe chamber 6 with the dry air.

[0057] It can be understood that in some of the embodiments, in order to meet the practical needs of users to reasonably adjust the blowing angle and the blowing air volume according to usage requirements, the damper 10 is an air outlet guide blade that can adjust the air outlet size and air outlet angle.

[0058] Please refer to Figure 6 In some embodiments, the new dehumidifier also includes a capillary flow tube 20 arranged between the evaporator 2 and the condenser 3. The capillary flow tube 20 connects the evaporator 2 and the condenser 3. The low-temperature and high-pressure liquid refrigerant discharged from the condenser 3 can be converted into a low-temperature and low-pressure liquid refrigerant through the capillary flow tube 20. The low-temperature and low-pressure liquid refrigerant then enters the evaporator 2 and becomes a low-temperature and low-pressure gaseous refrigerant. The low-temperature and low-pressure gaseous refrigerant then returns to the compressor 4 for compression processing, and the cycle continues.

[0059] Please refer to Figure 1 , Figure 5 and Figure 7 In some embodiments, the novel dehumidifier further includes a water receiving tray 60 disposed at the bottom of the evaporator 2, a water tank 50 for storing condensed water, and a water pump 70 for conveying condensed water in the water receiving tray 60 to the water tank 50. The water tank 50 is disposed at the top of the housing assembly 1, and the water pump 70 is disposed in the water receiving tray 60. The water pump 70 is connected to the water tank 50 through a water pipe. In order to facilitate the movement of the dehumidifier, four casters 40 are also provided at the bottom of the housing assembly 1.

[0060] Please refer to Figure 1 , Figure 7 , Fig.11 and Fig.16In some embodiments, the housing assembly 1 includes a housing body 17 and a cover body 18 detachably connected to the housing body 17. A receiving chamber 19 for receiving the water tank 50 and a receiving port 90 for placing the water tank 50 into or taking out the receiving chamber 19 are provided in the housing body 17 near the top of the housing body 17. The cover body 18 is used to open or close the receiving port 90. In this embodiment, a receiving chamber 19 and a receiving port 90 communicating with the receiving chamber 19 are provided in the housing body 17 near the top of the housing body 17. The user can place a large-capacity water tank 50 into or take out the receiving chamber 19 through the receiving port 90. By arranging the water tank 50 at the upper part of the housing body 17, the upper water tank structure is more convenient for the user to take the water tank 50 than the lower water tank structure.

[0061] Please refer to Figure 1 , Figure 2 and Fig.11 In some embodiments, the novel dehumidifier further includes at least one water tank 50 hidden in the accommodating cavity 19, and the water tank 50 is detachably installed in the accommodating cavity 19. Compared with the external water tank structure, the hidden internal water tank structure makes the overall appearance of the novel dehumidifier more beautiful, and the cover body 18 is used to close the accommodating port 90, which can ensure the integrity and aesthetics of the novel dehumidifier.

[0062] Please refer to Figure 1 , Figure 8 and Fig. 9 In some embodiments, a noise reduction and silencing structure 8 is further provided inside the housing assembly 1 for blocking the noise generated by the compressor 4 from being transmitted to the air outlet 12 through the air duct. The noise reduction and silencing structure 8 includes a soundproof cover 81 for covering the compressor 4 and a silencer 82 arranged on the inner wall of the soundproof cover 81. The soundproof cover 81 is arranged in the second heat exchange cavity 14. When the compressor 4 is accommodated in the soundproof cover 81, the soundproof cover 81 independently isolates the compressor 4 in the air duct composed of the first heat exchange cavity 13 and the air supply cavity 15, so as to reflect and / or isolate the noise generated by the compressor 4 when it is running, so as to block the noise generated by the compressor 4 when it is running from being transmitted to the air outlet 12 through the air duct, thereby preventing the harsh noise generated by the compressor 4 when it is running from being transmitted to the room through the air outlet 12, eliminating the impact of the harsh noise generated by the compressor 4 when it is running on the user's life and rest, and improving the comfort of the user when using the dehumidifier.

[0063] Please refer to Figure 8 , Fig. 9 and Fig.10In some of the embodiments, a silencer 811 for absorbing, reflecting or isolating sound is provided at a position corresponding to each heat dissipation hole 16 on the sound insulation cover 81, which can block the noise transmitted through the heat dissipation hole 16, and is helpful to prevent the harsh noise generated by the compressor 4 during operation from being transmitted to the room through the air outlet 12.

[0064] Please refer to Fig.11 , Fig.14 and Fig.15 In some embodiments, the fan 5 includes a volute 51 with a centrifugal air duct 511 and an exhaust air duct 512 inside, a centrifugal wind wheel 52 arranged in the centrifugal air duct 511 and a motor for driving the centrifugal wind wheel 52 to work, the motor is arranged on the volute 51, and the volute 51 is provided with a first air suction port 513 and a second air suction port 514 connected to the centrifugal air duct 511, the first air suction port 513 and the second air suction port 514 together constitute an air suction channel, and the first air suction port 513 and the second air suction port 514 are respectively connected to the second heat exchange chamber 14.

[0065] Please refer to Fig.12 , Fig.13 and Fig.16 In some embodiments, since the air outlet 12 is located on the side of the housing component 1 and near the top of the housing component 1, the exhaust duct 512 is extended obliquely upward from the center of the housing component 1 toward the air outlet 12, so that the dry air processed by the evaporator 2 and the condenser 3 can be discharged obliquely upward into the room through the air outlet 12. Compared with the vertical upward exhaust of the air outlet 12 at the top of the housing, the exhausted dry air can be transmitted to a farther position, which is conducive to promoting the circulation of indoor air and achieving the requirement of quickly reducing indoor humidity. It can also avoid the dry air discharged from the air outlet 12 from blowing directly on people, thereby improving the user's comfort. Specifically, the angle between the center line of the exhaust duct 512 and the horizontal plane is 45° to 60°, which can make the dry air processed by the evaporator 2 and the condenser 3 finally be discharged obliquely upward into the room through the air outlet 12 under the oblique upward guidance of the exhaust duct 512.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
