Description

Technical Field

[0001] The present application relates to the technical field of dehumidifiers, and in particular to a high and low temperature adaptive dehumidifier. Background Art

[0002] A dehumidifier is a device commonly used to remove excess moisture from the air. It is widely used in homes, offices, warehouses, museums and other places to prevent moisture, mold and keep the environment dry. The basic working principle of a dehumidifier is to condense the moisture in the air into water droplets through the condensation process and expel the moisture from the room, thereby reducing the humidity of the environment. As the humidity of the air is reduced, the dehumidifier helps improve comfort, prevent mold growth, and protect items from moisture damage.

[0003] Although the dehumidifiers of the prior art have solved the problem of excessive indoor air humidity to a certain extent, the following problems still exist. 1. When the ambient temperature is low, the evaporator inside the dehumidifier will be frosted or iced, resulting in a decrease in the heat exchange efficiency between the evaporator and the air, affecting the dehumidification effect, and may even cause equipment failure, resulting in a small dehumidification amount and great difficulty in dehumidification under low temperature conditions. 2. When the ambient temperature is high, due to the fixed structure between the evaporator and the condenser, the condenser has a poor effect of dissipating heat to the outside, causing the compressor to be in a high-load motion state for a long time, which is prone to overheating and tripping problems, affecting the normal operation of the dehumidifier. 3. When the compressor is in a high-load working state, it will itself cause the vibration of the dehumidifier to intensify, which in turn causes the dehumidifier to make loud noises when working. Summary of the invention

[0004] In order to solve the problems raised in the above background technology that the existing dehumidifiers have low dehumidification capacity and great dehumidification difficulty under low temperature conditions, and are prone to high equipment noise or even machine tripping under high temperature conditions, the present application provides a high and low temperature adaptive dehumidifier.

[0005] The application provides a high and low temperature adaptive dehumidifier adopts the following technical solution: A high and low temperature adaptive dehumidifier comprises a base frame, on which a relatively movable evaporator and condenser are mounted, and temperature sensors are respectively mounted on the evaporator and condenser. When the temperature sensor detects that the outer surface temperature of the evaporator exceeds a threshold value and / or the external temperature of the condenser exceeds a threshold value, the distance between the evaporator and the condenser can be reduced to adjust the external temperature of the evaporator and / or the condenser so that the dehumidifier can run smoothly.

[0006] By adopting the above technical solution, the distance between the evaporator and the condenser can be changed according to the external environment temperature and the operating conditions of the equipment during operation to meet the purpose of normal operation of the equipment. Specifically, the temperature of the two devices is monitored in real time through the temperature sensors installed on the evaporator and the condenser. For example, when the ambient temperature is low, the dehumidifier is prone to frost or ice on the evaporator surface during operation. At this time, the temperature sensor detects that the evaporator surface temperature is lower than the threshold value, and the distance between the evaporator and the condenser will be reduced through the control system of the dehumidifier, so that the evaporator can be close to the condenser, and the heat dissipated by the condenser can be used on the evaporator surface, which can effectively prevent the evaporator surface from frosting or icing, and can quickly achieve the effect of defrosting and deicing, which is conducive to the dehumidifier to smoothly dehumidify under low temperature conditions and avoid the phenomenon of reduced dehumidification. For example, when the ambient temperature is high, the condenser cannot dissipate heat quickly, and the temperature sensor installed on the condenser detects that the temperature is higher than the threshold, causing the compressor load to increase. At this time, the control system reduces the distance between the evaporator and the condenser, and the cold energy dissipated by the evaporator can form heat exchange with the condenser, thereby improving the heat dissipation effect of the condenser and keeping the compressor load stable at all times, so as to solve the problem of large vibration, loud noise, and even machine tripping caused by heavy load under high temperature conditions.

[0007] Optionally, the base frame includes a lower frame located below the evaporator and the condenser, and an upper frame close to the condenser. The upper frame and the lower frame are connected to each other. A fan is installed on the side of the upper frame away from the condenser, and the fan has an air outlet channel extending upward.

[0008] By adopting the above-mentioned technical solution, the base frame is designed as a detachable connection structure consisting of an upper frame and a lower frame, so as to facilitate the assembly of the internal components of the dehumidifier and subsequent maintenance work. Among them, an evaporator and a condenser are arranged on one side of the upper frame, and a fan is arranged on the other side. The compactness of the internal components of the dehumidifier can be maximized, and the fan is used to quickly discharge the dehumidified air to the outside of the machine, which is beneficial to improve the dehumidification effect.

[0009] Optionally, the fan is a centrifugal fan, and the external air passes through the evaporator and the condenser in sequence before entering the fan and being discharged upward from an air outlet channel.

[0010] By adopting the above technical solution, the external air is introduced into the dehumidifier by means of induced air to perform dehumidification, and then introduced upward into the air after dehumidification is completed. That is, when the hot air is blown upward along the air outlet channel, the hot air will rise rapidly and form convection with the cold air in the room, so that the dry air processed by the dehumidifier is spread to every corner of the room faster, thereby improving the dehumidification effect. In addition, since the hot air is blown upward, it can avoid the problem of directly blowing on the human body or other objects, thereby causing damage to the objects.

[0011] Optionally, it also includes an outer shell, the base frame is installed inside the outer shell, the outer shell includes a top cover, a rear shell, a front shell, a base, a water tank and an air inlet grille, and the surface of the top cover is provided with an air outlet connected to the air outlet channel; the air inlet grille is installed on the surface of the front shell and is configured so that outside air can pass through the air inlet grille into the inner part of the outer shell.

[0012] By adopting the above technical solution, the base frame, evaporator, condenser, etc. are hidden inside the outer shell, making the overall structure of the equipment more simple and beautiful. The outer shell includes a front shell and a rear shell, which can facilitate the early assembly of the equipment and subsequent maintenance, thereby improving convenience.

[0013] Optionally, a water collecting trough is provided on the surface of the lower frame, and the evaporator and condenser are located above the water collecting trough. Water generated by the evaporator and condenser during operation can flow downward into the water collecting trough. A water drain hole is provided at the bottom of the water collecting trough, and the water drain hole is connected to the inner cavity of the water tank.

[0014] By adopting the above technical solution, the water generated by the evaporator and the condenser during operation can flow into the water collecting tank and then flow into the water tank through the drain hole, thereby achieving the water collection effect.

[0015] Optionally, the evaporator is movably mounted on a base frame, and a driving mechanism for driving the evaporator to move is mounted on the base frame.

[0016] By adopting the above technical solution, in actual operation, the distance between the evaporator and the condenser is adjusted by controlling the movement of the evaporator. This is because the evaporator is closer to the outside of the dehumidifier compared to the condenser, and there is more space to achieve the effect of moving the evaporator, making the distance adjustment scheme between the evaporator and the condenser more compact.

[0017] Optionally, the driving mechanism includes a plurality of first sliding rods installed on the evaporator, the length directions of the plurality of first sliding rods are arranged parallel to each other, and also includes a first guide shell installed on the base frame, the first sliding rod is installed in a channel formed by the first guide shell and the base frame, and a connecting rod driving assembly for driving the first sliding rod to move is installed on the first sliding rod.

[0018] By adopting the above technical solution, the first guide shell is installed on the base frame, and the first sliding rod is slidably installed in the channel formed by the first guide shell and the base frame, so that the first sliding rod can achieve the effect of reciprocating movement on one of the three-dimensional axes, thereby achieving the purpose of adjusting the distance between the evaporator and the condenser, and will not have an adverse effect on other components inside the dehumidifier when the evaporator moves.

[0019] Optionally, the connecting rod drive assembly includes a fixed plate installed on a base frame, a motor is installed on one side of the fixed plate, the output shaft of the motor passes through the fixed plate and is connected to an active connecting rod installed on the other side of the fixed plate, and a plurality of driven connecting rods connected end to end are connected at both ends of the active connecting rod, and a connecting block is hinged at the end of the driven connecting rod, which is interconnected with the first sliding rod.

[0020] Optionally, the middle position of the driven connecting rod has a limit pin protruding outward, and the surface of the fixed plate is provided with a plurality of strip holes matching the limit pins, the length direction of the strip holes is consistent with the length direction of the fixed plate, and the limit pin is placed in the strip hole and can move and rotate in the strip hole.

[0021] By adopting the above technical solution, after the motor is started, the active connecting rod can rotate, and the active connecting rod drives multiple driven connecting rods at both ends to rotate, so that the movable connecting rod at the end position can finally drive the connecting block to move, and then drive the first sliding rod to move, so as to achieve the purpose of moving the evaporator. This connecting rod drive assembly can reduce the space it occupies inside the dehumidifier, and has the advantages of simple structure and stable driving effect.

[0022] Optionally, the condenser is movably mounted on a base frame.

[0023] The purpose of adopting the above technical solution is mainly because the surface of the evaporator will have a certain thickness when it is frozen. This increased thickness structure and the movable characteristics of the evaporator itself can avoid damaging the condenser during the movement of the evaporator, allowing the condenser to move a certain distance, thereby achieving a safety buffer effect.

[0024] Optionally, a plurality of second sliding rods are installed on the condenser, and a second guide shell matching the second sliding rod is installed on the base. The second sliding rod is slidably connected in a channel formed by the second guide shell and the base. A spring is installed at the end of the second sliding rod. The spring is sleeved on the outer diameter position of a cylindrical boss extending horizontally outward from the side of the base, and one end of the spring is abutted against the second sliding rod and the other end is abutted against the base.

[0025] By adopting the above technical solution, the condenser can achieve the moving effect under the structure of the second sliding rod and the second guide shell, and when the condenser moves to the extreme position, it can contact the base frame through the spring to avoid the collision between the condenser and the base frame. It can prevent the condenser from being damaged during the movement of the evaporator and also avoid the condenser from colliding with the base frame when it moves.

[0026] Optionally, it also includes copper tubes connected to the evaporator and the condenser respectively, the ends of the copper tubes are connected to a compressor, the compressor is connected to the base frame, and the copper tubes are bent in the middle to form at least one U-shaped structure.

[0027] By adopting the above technical solution, a compressor is used to compress the refrigerant inside the copper tube, and the U-shaped copper tube can avoid damage to the copper tube itself during the movement of the evaporator and the condenser.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: The invention has a simple and exquisite design structure, and can change the distance between the evaporator and the condenser according to the external environment temperature and the operating conditions of the equipment during operation to meet the purpose of normal operation of the equipment.

[0029] When the ambient temperature is low, the dehumidifier is prone to frost or ice on the evaporator surface when working. At this time, the distance between the evaporator and the condenser is reduced so that the evaporator can be close to the condenser. The heat dissipated by the condenser can be used on the evaporator surface to effectively prevent frost or ice on the evaporator surface and quickly achieve defrosting and deicing effects. This is beneficial for the dehumidifier to dehumidify smoothly under low temperature conditions and avoid the phenomenon of reduced dehumidification.

[0030] When the ambient temperature is high, the condenser cannot dissipate heat quickly, which will cause the load on the compressor to increase. At this time, reducing the distance between the evaporator and the condenser allows the cold energy dissipated from the evaporator to form heat exchange with the condenser, thereby improving the heat dissipation effect of the condenser and keeping the compressor load stable at all times, in order to solve the problem of large vibration, loud noise, and even machine tripping caused by heavy load under high temperature conditions.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] As shown in the figure, the embodiment of the present application discloses a high and low temperature adaptive dehumidifier, including an outer shell and a base frame, and the base frame is installed inside the outer shell. The outer shell includes a top cover 1, a rear shell 2, a front shell 3, a base 6, a water tank 5 and an air inlet grille 4. The front shell 3 and the rear shell 2 are connected by bolts. The bottom of the base 6 is provided with moving wheels to facilitate the movement of the dehumidifier. A control circuit board is provided inside the top cover 1, and a touch screen is provided on its surface for controlling the dehumidifier to work.

[0035] An evaporator 12 and a condenser 13 are mounted on the base frame and are movable relative to each other. Temperature sensors 21 are mounted on the evaporator 12 and the condenser 13, respectively. When the temperature sensor 21 detects that the outer surface temperature of the evaporator 12 exceeds a threshold value and / or the external temperature of the condenser 13 exceeds a threshold value, the distance between the evaporator 12 and the condenser 13 can be reduced to adjust the external temperature of the evaporator 12 and / or the condenser 13 so that the dehumidifier can run smoothly. The structures of the evaporator 12 and the condenser 13 are conventional settings in the prior art and will not be elaborated on herein.

[0036] Among them, the base frame includes a lower frame 11 located below the evaporator 12 and the condenser 13, and an upper frame 8 close to the condenser 13. The upper frame 8 is connected to the lower frame 11. A fan 7 is installed on the side of the upper frame 8 away from the condenser 13. The fan 7 has an air outlet channel 701 extending upward. Specifically, the fan 7 is a centrifugal fan 7 (the specific structure and principle of the centrifugal fan 7 belong to conventional means in the prior art and will not be described in detail here). The external air passes through the evaporator 12 and the condenser 13 in turn and then enters the fan 7, and is guided upward from the air outlet channel 701. That is, the external air realizes two working processes of dehumidification and heating in the process of passing through the evaporator 12 and the condenser 13. The air guided from the air outlet channel 701 is dry hot air, which is introduced into the air to achieve a dehumidification effect.

[0037] An air outlet connected to the air outlet channel 701 is provided on the surface of the top cover 1, so that the dry hot air can be discharged from the air outlet channel 701 and then discharged up and down through the top cover 1; the air inlet grille 4 is installed on the surface of the front shell 3, and is configured so that the outside air can pass through the air inlet grille 4 to enter the outer shell.

[0038] Specifically, a water collecting trough 1102 is provided on the surface of the lower frame 11, and the evaporator 12 and the condenser 13 are located above the water collecting trough 1102. The water generated by the evaporator 12 and the condenser 13 during operation can flow downward into the water collecting trough 1102. A water discharge hole 1103 is provided at the bottom of the water collecting trough 1102, and the water discharge hole 1103 is connected to the inner cavity of the water tank 5. More specifically, the water flowing down from the evaporator 12 is melted water of frost or ice, and the water flowing down from the condenser 13 is condensed water during the dehumidification process.

[0039] In this embodiment, the evaporator 12 is movably mounted on a base frame, and a driving mechanism for driving the evaporator 12 to move is mounted on the base frame.

[0040] Specifically, the driving mechanism includes a plurality of first sliding rods 20 installed on the evaporator 12, and the length directions of the plurality of first sliding rods 20 are arranged parallel to each other. In this example, there are four first sliding rods 20, and the four first sliding rods 20 are respectively installed at the four corners of the evaporator 12 to achieve a smooth effect during the movement of the evaporator 12.

[0041] The first guide housing 19 is mounted on the base frame, and the first sliding rod 20 is mounted in the channel formed by the first guide housing 19 and the base frame. The cross section of the first guide housing 19 is a U-shaped structure, and the first sliding rod 20 is located in the U-shaped groove of the U-shaped structure. The first sliding rod 20 is limited by the first guide housing 19 and the base frame, so that the first sliding rod 20 has only the freedom to move forward and backward. More specifically, in order to limit the stroke of the first sliding rod 20, a rectangular window 2001 is opened on the first sliding rod 20, and a bolt with a small diameter is passed through the rectangular window 2001 and connected to the base frame, so that the forward and backward stroke of the first sliding rod 20 can be limited. A connecting rod driving assembly for driving the first sliding rod 20 to move is installed on the first sliding rod 20 .

[0042] Among them, the connecting rod driving assembly includes a fixed plate 15 installed on the base frame, and there are two fixed plates 15, which are respectively arranged on the left and right sides of the base frame. A mounting hole 1501 is opened on the base frame, and the fixed plate 15 is connected to the base frame by bolts; a motor 14 is installed on one side of the fixed plate 15, and the output shaft of the motor 14 passes through the fixed plate 15 and is connected to an active connecting rod 16 installed on the other side of the fixed plate 15. The two ends of the active connecting rod 16 are connected to a plurality of driven connecting rods 17 connected end to end, and the end of the driven connecting rod 17 is hinged with a connecting block 18, and the connecting block 18 is connected to the first sliding rod 20. The end of the driven connecting rod 17 is inserted into the long hole opened on the connecting block 18 through a pin shaft, so that when the end of the driven connecting rod 17 swings, the pin shaft can slide and rotate in the long hole.

[0043] Specifically, the middle position of the driven connecting rod 17 has a limit pin 1701 protruding outward, and the surface of the fixed plate 15 is provided with a plurality of strip holes 1502 matching the limit pin 1701. The length direction of the strip hole 1502 is consistent with the length direction of the fixed plate 15. The limit pin 1701 is placed in the strip hole 1502 and can move and rotate in the strip hole 1502. During specific operation, the motor 14 drives the active connecting rod 16 to rotate, and the active connecting rod 16 drives the driven connecting rod 17 to swing. When the active connecting rod 16 rotates from the inclined direction to the vertical direction, the driven connecting rod 17 at the end can move the connecting block 18, the first sliding rod 20 and the evaporator 12 in the direction close to the condenser 13, thereby achieving the effect of reducing the gap between the evaporator 12 and the condenser 13. Conversely, the distance between the evaporator 12 and the condenser 13 becomes larger.

[0044] In this example, the condenser 13 is movably mounted on a base frame.

[0045] Specifically, a plurality of second sliding rods 24 are installed on the condenser 13, and a second guide shell 23 matching the second sliding rod 24 is installed on the base. The second sliding rod 24 is slidably connected in a channel formed by the second guide shell 23 and the base. A spring 22 is installed at the end of the second sliding rod 24. The spring 22 is sleeved on the outer diameter position of a cylindrical boss 1101 extending horizontally outward from the side of the base, and one end is abutted against the second sliding rod 24 and the other end is abutted against the base.

[0046] In this example, there are also four second sliding rods 24, which are respectively installed at the four corners of the condenser 13 to ensure the smooth movement of the condenser 13. Similar to the structure of the first guide housing 19, the cross-section of the second guide housing 23 is also a U-shaped structure. The second sliding rod 24 is placed in the U-shaped groove of the U-shaped structure. The second sliding rod 24 has only the freedom to move in the front and rear directions. In order to limit the front and rear travel of the second sliding rod 24, a round hole 2401 is opened on the second sliding rod 24. By inserting a bolt smaller than the round hole 2401 and installing the bolt on the base frame (in this example), the second sliding rod 24 is provided with a round hole 2401. In the example, on the lower frame 11), the purpose of slightly moving the second sliding rod 24 can be met. When working, the evaporator 12 moves toward the condenser 13. Since the surface of the evaporator 12 will freeze, the initial distance between the evaporator 12 and the condenser 13 can be reduced. The evaporator 12 will hit the condenser 13 when it moves, and the condenser 13 is set with a movable structure. When the evaporator 12 contacts the condenser 13, the condenser 13 can move slightly, thereby avoiding the problem of damage to the evaporator 12 or the condenser 13 due to impact, which is beneficial to extending the service life of the two.

[0047] Specifically, temperature sensors 21 are installed on the evaporator 12 and the condenser 13. The two temperature sensors 21 are respectively used to monitor the real-time temperature of the evaporator 12 and the condenser 13 during operation. They can provide feedback on the temperature of the equipment under different working conditions, and further reflect the load size of the equipment compressor 10, so as to facilitate real-time adjustment of the distance between the evaporator 12 and the condenser 13 through the controller of the equipment, so as to keep the load of the compressor 10 relatively balanced.

[0048] Specifically, it also includes a copper tube 9 connected to the evaporator 12 and the condenser 13 respectively, the end of the copper tube 9 is connected to the compressor 10, the compressor 10 is connected to the base frame, and the copper tube 9 is bent in the middle to form at least one U-shaped structure. More specifically, in this embodiment, a soft copper tube 9 can be selected to cooperate with the movement of the evaporator 12 and the condenser 13 to avoid damage to the copper tube 9.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
