Description

Technical Field

[0001] This utility model relates to the field of material dehumidification technology, and in particular to a dehumidification and drying device. Background Technology

[0002] Dehumidification technology has received much attention worldwide in recent years. However, existing dehumidifiers on the market are limited by their operating environment. The ambient temperature that most dehumidifiers are suitable for is generally low, usually below 35°C. As dehumidification operations are developing towards industrial applications, more and more agricultural and industrial products need to be dried using dehumidifiers in drying rooms. However, when the temperature inside the drying room rises, the dehumidifier is in a high-temperature environment. The dehumidifier usually suffers from poor dehumidification effect due to the compressor overheating, which affects the efficiency of the drying process. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a dehumidification and drying device that can improve the evaporative dehumidification effect, improve the heat dissipation effect of the condenser, and reduce the temperature of the compressor during operation.

[0004] To achieve the above objectives, this utility model provides a dehumidification and drying device, which includes a dehumidification component and an air inlet assembly. The dehumidification component includes a mounting plate, a compressor, a condenser, a throttling valve, and a dehumidification evaporator. The compressor, the condenser, the throttling valve, and the dehumidification evaporator are sequentially connected. The dehumidification evaporator is connected to the compressor. A first port is provided in the middle of the condenser. A second port is provided in the middle of the dehumidification evaporator. The condenser and the dehumidification evaporator are arranged opposite to each other and spaced apart along a first horizontal direction, and both the first port and the second port are through-through along the first horizontal direction. Two mounting plates are provided and are arranged along a second horizontal direction. The condenser and the dehumidifying evaporator are respectively positioned so that their two ends abut against the opposite side faces of the two mounting plates; an air inlet is defined between the upper parts of the two mounting plates, the upper part of the condenser, and the upper part of the dehumidifying evaporator; wherein the first horizontal direction and the second horizontal direction are perpendicular to each other; the air inlet assembly includes a fan, a damper, and a cover plate; the cover plate is rotatably disposed at the air inlet; the damper is disposed on the mounting plate and connected to the cover plate; the damper can drive the cover plate to rotate, thereby enabling the cover plate to close and open the air inlet; the fan is disposed on the side of the condenser away from the dehumidifying evaporator and is connected to the first inlet.

[0005] Furthermore, the dehumidification component also includes a heat-absorbing evaporator; one end of the heat-absorbing evaporator is connected to the dehumidification evaporator, and the other end of the heat-absorbing evaporator is connected to the compressor, so that the dehumidification evaporator and the compressor are connected.

[0006] Furthermore, the dehumidification component also includes a heat-absorbing fan, which is located on one side of the heat-absorbing evaporator and is positioned towards the heat-absorbing evaporator.

[0007] Furthermore, the air intake assembly also includes a rotating shaft; there are two rotating shafts, each rotatably mounted on one of the two mounting plates; the axis of the rotating shaft is aligned with the second horizontal direction; both rotating shafts are connected to the cover plate, and the air valve is connected to one of the rotating shafts and can drive the rotating shaft to rotate.

[0008] Furthermore, the air intake assembly also includes a temperature sensor; the temperature sensor is connected to the mounting plate and electrically connected to the air valve; the temperature sensor is used to detect the temperature of the compressor.

[0009] Furthermore, the dehumidification component also includes a water tray; the water tray is provided with a water-containing cavity and an opening, the opening is located at the top of the water tray and is connected to the water-containing cavity; the condenser and the dehumidification evaporator are both located at the top of the water tray.

[0010] Furthermore, a drain outlet is provided at the lower side of the water tray, and the drain outlet is connected to the water-containing cavity.

[0011] Furthermore, it also includes a mounting base, with both the water tray and the compressor located at the top of the mounting base.

[0012] Furthermore, in the second horizontal direction, the compressor is located on one side of the fan.

[0013] Furthermore, a first baffle and a second baffle are provided at the top edge of the mounting base; the first baffle and the second baffle are arranged opposite to each other and spaced apart along the first horizontal direction; the first baffle abuts against the fan, and the second baffle abuts against the water tray.

[0014] Compared with the prior art, this utility model has the following advantages: 1. Since the compressor, condenser, expansion valve and dehumidifying evaporator are connected in sequence, the compressor can compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gaseous refrigerant, and input the refrigerant into the condenser. The high-temperature and high-pressure gaseous refrigerant flows through the condenser tube of the condenser, releases heat to the outside, and condenses into a medium-temperature and high-pressure liquid refrigerant. After the high-pressure liquid refrigerant flows through the expansion valve, the pressure drops and it becomes a mixture of low-temperature and low-pressure liquid and gas. The low-temperature and low-pressure liquid and gas mixture is in the evaporator tube of the dehumidifying evaporator. Through the evaporator tube, it exchanges temperature with the outside air with high humidity, so that the water vapor in the air condenses into water, thereby removing the water vapor in the air, reducing the humidity of the air, and achieving the effect of condensation and dehumidification. The refrigerant in the evaporator tube then returns to the compressor to complete the cycle.

[0015] 2. The fan and condenser are connected to the side furthest from the dehumidifying evaporator and are connected to the first inlet. When the compressor temperature is appropriate, starting the fan allows air to enter the first inlet from the second inlet and then flow out through the fan, thus improving the evaporative dehumidification effect. Furthermore, the two ends of the condenser and dehumidifying evaporator abut against the opposite side faces of the two mounting plates, ensuring air can flow through the first inlet, improving the condenser's heat dissipation efficiency, ensuring condensation effect, and thus reducing the temperature of the compressor during cyclic compression. An air inlet is formed between the upper parts of the two mounting plates, the upper part of the condenser, and the upper part of the dehumidifying evaporator. When the compressor temperature is too high, the cover plate can be rotated by the air valve, allowing the air inlet to connect with the outside air. The connection between the condenser and the dehumidifying evaporator increases the air intake. When the fan is working, outside air enters from the air inlet between the condenser and the dehumidifying evaporator, and then flows through the first inlet to further improve the heat dissipation of the condenser and reduce the temperature of the compressor during cyclic compression. On the other hand, the air valve drives the cover plate to rotate, which can reduce the air volume passing through the dehumidifying evaporator. Even if the ambient temperature of the dehumidifying drying device is high, the dehumidifying evaporator can still dehumidify at a lower temperature. By improving the condensing effect of the condenser and lowering the temperature of the condenser, the temperature of the compressor during cyclic compression is reduced. Furthermore, by reducing the air volume of the dehumidifying evaporator, the dehumidifying evaporator can be dehumidified at a lower temperature, which can further reduce the operating temperature of the compressor.

Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0027] like Figures 1 to 5As shown, according to an embodiment of the present invention, the dehumidifying and drying device includes a dehumidifying component 100 and an air inlet assembly. The dehumidifying component 100 includes a mounting plate 110, a compressor 120, a condenser 130, a throttle valve 140, and a dehumidifying evaporator 150. The compressor 120, condenser 130, throttle valve 140, and dehumidifying evaporator 150 are sequentially connected. The dehumidifying evaporator 150 is connected to the compressor 120. A first opening is provided in the middle of the condenser 130, and a second opening is provided in the middle of the dehumidifying evaporator 150. The condenser 130 and the dehumidifying evaporator 150 are arranged opposite each other and spaced apart along a first horizontal direction, and both the first opening and the second opening are connected through each other along the first horizontal direction. Two mounting plates 110 are provided and are arranged opposite each other along a second horizontal direction. The condenser 130 and the dehumidifying evaporator 150 are respectively positioned so that their two ends abut against the opposite side faces of the two mounting plates 110; an air inlet 111 is defined between the upper parts of the two mounting plates 110, the upper parts of the condenser 130 and the upper parts of the dehumidifying evaporator 150; wherein the first horizontal direction and the second horizontal direction are perpendicular to each other; the air inlet assembly includes a fan 210, an air valve 220 and a cover plate 230; the cover plate 230 is rotatably disposed at the air inlet 111; the air valve 220 is disposed on the mounting plate 110 and connected to the cover plate 230; the air valve 220 can drive the cover plate 230 to rotate so that the cover plate 230 can close and open the air inlet 111; the fan 210 is disposed on the side of the condenser 130 away from the dehumidifying evaporator 150 and is connected to the first opening.

[0028] 1. Since the compressor 120, condenser 130, expansion valve 140 and dehumidifying evaporator 150 are connected in sequence, the compressor 120 can compress the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gaseous refrigerant and input the refrigerant into the condenser 130. The high-temperature, high-pressure gaseous refrigerant flows through the condenser tube 131 of the condenser 130, releases heat to the outside, and condenses into a medium-temperature, high-pressure liquid refrigerant. After the high-pressure liquid refrigerant flows through the expansion valve 140, the pressure drops and it becomes a mixture of low-temperature, low-pressure liquid and gas. The low-temperature, low-pressure liquid and gas mixture is in the evaporator tube 151 of the dehumidifying evaporator 150. Through the evaporator tube 151, it exchanges temperature with the outside air with high humidity, causing water vapor in the air to condense into water, thereby removing the water vapor in the air, reducing the humidity of the air, and achieving the effect of condensation and dehumidification. The refrigerant in the evaporator tube 151 then returns to the compressor 120 to complete the cycle.

[0029] 2. The fan 210 is connected to the side of the condenser 130 away from the dehumidifying evaporator 150 and is connected to the first port. When the compressor 120 is at a reasonable temperature, starting the fan 210 allows air to enter the first port from the second port and then flow out through the fan 210, thereby improving the evaporative dehumidification effect. Furthermore, the two ends of the condenser 130 and the dehumidifying evaporator 150 respectively abut against the opposite side surfaces of the two mounting plates 110, ensuring that air can flow through the first port, improving the heat dissipation efficiency of the condenser 130, ensuring the condensing effect, and thus reducing the temperature of the compressor 120 during cyclic compression. An air inlet 111 is formed between the upper parts of the two mounting plates 110, the upper parts of the condenser 130, and the upper parts of the dehumidifying evaporator 150. When the temperature of the compressor 120 is too high, the cover plate 230 can be rotated by the air valve 220, allowing the air inlet 111 to open. 1. By connecting to the outside environment and increasing the air intake, when the fan 210 is working, outside air enters from the air inlet 111 between the condenser 130 and the dehumidifying evaporator 150, and then flows through the first port to further improve the heat dissipation effect of the condenser 130 and reduce the temperature of the compressor 120 during cyclic compression. On the other hand, the air valve 220 drives the cover plate 230 to rotate, which can reduce the air volume passing through the dehumidifying evaporator 150. Even if the ambient temperature of the dehumidifying and drying device is high, the dehumidifying evaporator 150 can still dehumidify at a lower temperature. By improving the condensing effect of the condenser 130, the temperature of the condenser 130 is reduced, thereby reducing the temperature of the compressor 120 during cyclic compression. Furthermore, by reducing the air volume of the dehumidifying evaporator 150, the dehumidifying evaporator 150 can be dehumidified at a lower temperature. The lower temperature of the dehumidifying evaporator 150 can further reduce the operating temperature of the compressor 120.

[0030] Specifically, the first port and the second port are arranged opposite each other in the first horizontal direction; the compressor 120, the condenser 130, the throttle valve 140 and the dehumidifying evaporator 150 are all connected in sequence through a pipe structure; the throttle valve 140 is located on one side of a mounting plate 110.

[0031] Reference Figure 5 In some embodiments of this utility model, the dehumidification component 100 further includes a heat-absorbing evaporator 180; one end of the heat-absorbing evaporator 180 is connected to the dehumidification evaporator 150, and the other end of the heat-absorbing evaporator 180 is connected to the compressor 120, so that the dehumidification evaporator 150 and the compressor 120 are connected.

[0032] When the temperature inside the drying chamber is low, and the ambient temperature of the dehumidifying and drying device is low, a heat-absorbing evaporator 180 is added outside the drying chamber. One end of the heat-absorbing evaporator 180 is connected to the dehumidifying evaporator 150. The refrigerant in the dehumidifying evaporator 150 flows into the heat-absorbing evaporator 180, so that the refrigerant exchanges heat in the heat-absorbing evaporator 180 to exchange energy with the outside, thereby increasing the temperature of the refrigerant. This results in a higher temperature of the refrigerant flowing from the heat-absorbing evaporator 180 into the compressor 120.

[0033] Specifically, the two ends of the heat absorption evaporator 180 are connected to the dehumidification evaporator 150 and the compressor 120 through a pipe structure, so as to realize the mutual connection between the dehumidification evaporator 150 and the compressor 120.

[0034] Reference Figure 5 In some embodiments of this utility model, the dehumidification component 100 further includes a heat absorption fan 160, which is located on one side of the heat absorption evaporator 180 and is arranged towards the heat absorption evaporator 180.

[0035] By setting up a heat-absorbing fan 160, the gas can be blown towards the heat-absorbing evaporator 180, thereby increasing the efficiency of heat exchange between the higher-temperature outside air and the heat-absorbing evaporator 180, and thus improving the heat absorption efficiency of the heat-absorbing evaporator 180.

[0036] Reference Figure 1 In some embodiments of this utility model, the air intake assembly further includes a rotating shaft 240; two rotating shafts 240 are provided, and are rotatably mounted on two mounting plates 110 respectively; the axial direction of the rotating shaft 240 is arranged in the same direction as the second horizontal direction; both rotating shafts 240 are connected to the cover plate 230, and the air valve 220 is connected to one of the rotating shafts 240 and can drive the rotating shaft 240 to rotate.

[0037] By setting two pivots 240, the cover plate 230 can be limited to rotate around the second horizontal direction at the air inlet 111.

[0038] Specifically, rotating through holes are provided on the opposite side end faces of the mounting plate 110. One end of the rotating shaft 240 is rotatably inserted into the rotating through hole, and the other end of the rotating shaft 240 is connected to the cover plate 230. The air valve 220 is connected to one of the rotating shafts 240 and can drive the rotating shaft 240 to rotate, so as to drive the cover plate 230 to rotate around the second horizontal direction.

[0039] In some embodiments of this utility model, the air intake assembly further includes a temperature sensor; the temperature sensor is connected to the mounting plate 110 and electrically connected to the air valve 220; the temperature sensor is used to detect the temperature of the compressor 120.

[0040] By setting a temperature sensor, the temperature of the compressor 120 can be sensed and detected. When the temperature sensor detects that the temperature of the compressor 120 is higher than a predetermined value, the temperature sensor will activate the air valve 220, which will drive the cover plate 230 to rotate to increase the air intake.

[0041] Specifically, the temperature sensor is also electrically connected to the fan 210. When the temperature sensor detects that the temperature of the compressor 120 is higher than a predetermined value, the temperature sensor will start the fan 210.

[0042] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this utility model, the dehumidification component 100 further includes a water tray 170; the water tray 170 is provided with a water-containing cavity and an opening, the opening is provided at the top of the water tray 170 and is connected to the water-containing cavity; the condenser 130 and the dehumidification evaporator 150 are both provided at the top of the water tray 170.

[0043] By setting up a water tray 170, water droplets that condense and drip from the dehumidifying evaporator 150 can be contained, preventing water droplets from spreading in the drying room and affecting the normal operation of the dehumidifying drying device.

[0044] Reference Figure 1 and Figure 3 In some embodiments of this utility model, a drain outlet 171 is provided at the lower side of the water tray 170, and the drain outlet 171 is connected to the water-containing cavity.

[0045] By setting a drain outlet 171, water accumulated in the water pan 170 can be discharged from the drain outlet 171.

[0046] Specifically, the drain outlet 171 is located at the lower side of the water tray 170 so that the water in the water-containing cavity can be automatically discharged from the drain outlet 171 after accumulating to a predetermined horizontal level.

[0047] Reference Figure 1 and Figure 2 In some embodiments of this utility model, a mounting base 300 is also included, with a water tray 170 and a compressor 120 all disposed at the top of the mounting base 300.

[0048] The water tray 170 and compressor 120 can be raised by setting the mounting base 300, as well as the dehumidification component 100 and air intake assembly.

[0049] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of this utility model, in the second horizontal direction, the compressor 120 is located on one side of the fan 210.

[0050] The heat emitted by the compressor 120 can be transferred to the fan 210. Since the fan 210 operates at a low temperature, it can dissipate heat and thus cool down the compressor 120.

[0051] Reference Figures 1 to 4 In some embodiments of this utility model, a first baffle 310 and a second baffle 320 are provided at the top edge of the mounting base 300; the first baffle 310 and the second baffle 320 are arranged opposite to each other and spaced apart along a first horizontal direction; the first baffle 310 abuts against the fan 210 and the second baffle 320 abuts against the water tank.

[0052] The positions of the fan 210 and the water tank on the mounting base 300 can be defined by setting the first baffle 310 and the second baffle 320.

[0053] Specifically, the first baffle 310 can limit the fan 210 to move toward the direction closer to the condenser 130, while the second baffle 320 can limit the water pan 170 to move away from the fan 210, so as to prevent the water pan 170 from falling.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
