Description

Technical Field

[0001] This application relates to the field of dehumidifier technology, and in particular to a portable dehumidifier assembly. Background Technology

[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 dampness, mold, and maintain a dry environment. The basic working principle of a dehumidifier is to condense moisture in the air into water droplets through a condensation process and then expel the moisture from the room, thereby reducing the ambient humidity. As the air humidity decreases, dehumidifiers help improve comfort, prevent mold growth, and protect items from moisture damage.

[0003] While existing dehumidifiers have addressed the problem of excessive indoor humidity to some extent, the following issues remain: 1. In low ambient temperatures, frost or ice may form on the evaporator inside the dehumidifier, reducing heat exchange efficiency between the evaporator and the air, affecting dehumidification performance, and potentially causing equipment malfunction. This results in lower dehumidification capacity and greater difficulty in dehumidification at low temperatures. 2. In high ambient temperatures, the fixed structure between the evaporator and condenser reduces heat dissipation from the condenser, causing the compressor to operate under high load for extended periods. This can lead to overheating and shutdown, affecting the normal operation of the dehumidifier. 3. When the compressor operates under high load, it intensifies vibration, resulting in increased noise during operation. Utility Model Content

[0004] To address the problems mentioned in the background art, such as low dehumidification capacity and difficulty in dehumidification at low temperatures, and the tendency for excessive noise or even shutdown under high-temperature conditions, this application provides a portable dehumidification component.

[0005] The portable dehumidification component provided in this application adopts the following technical solution:

[0006] A portable dehumidification assembly includes a base frame on which a relatively movable evaporator and condenser are mounted. When the distance between the evaporator and condenser is reduced, the heat exchange efficiency between the evaporator and condenser can be improved, thereby quickly melting the frost or ice on the evaporator, achieving the effect of low-temperature dehumidification and increasing the amount of low-temperature dehumidification.

[0007] By adopting the above technical solutions, the distance between the evaporator and condenser can be adjusted according to the ambient temperature and operating conditions of the equipment during operation to ensure normal operation. For example, when the ambient temperature is low, the evaporator surface of the dehumidifier is prone to frost or ice buildup. In this case, reducing the distance between the evaporator and condenser allows the evaporator to be closer to the condenser, utilizing the heat dissipated by the condenser to act on the evaporator surface, quickly achieving defrosting and de-icing effects. This helps the dehumidifier to dehumidify smoothly even at low temperatures, avoiding a reduction in dehumidification capacity. Conversely, when the ambient temperature is high, the condenser cannot dissipate heat quickly enough, leading to a higher compressor load. Reducing the distance between the evaporator and condenser allows the cold air dissipated by the evaporator to exchange heat with the condenser, improving the condenser's heat dissipation effect and keeping the compressor load stable. This solves the problems of excessive vibration, noise, and even compressor shutdown caused by high loads at high temperatures.

[0008] Optionally, the evaporator is movably mounted on a base frame, on which a drive mechanism for moving the evaporator is mounted.

[0009] By adopting the above technical solution, the distance between the evaporator and the condenser can be adjusted by controlling the movement of the evaporator during actual operation. This is because the evaporator is located closer to the outside inside the dehumidifier than the condenser, allowing for more space to move and making the distance adjustment scheme between the evaporator and the condenser more compact.

[0010] Optionally, the drive mechanism includes a plurality of first sliding rods mounted on the evaporator, the plurality of first sliding rods being arranged parallel to each other in the length direction, and a first guide housing mounted on the base frame. The first sliding rods are installed in the channel formed by the first guide housing and the base frame, and a linkage drive assembly for driving the first sliding rods to move is mounted on the first sliding rods.

[0011] By adopting the above technical solution, the first guide housing is installed on the base frame, and the first sliding rod is slidably installed in the channel formed by the first guide housing and the base frame. This allows the first sliding rod to reciprocate on one of the three-dimensional axes, thereby achieving the purpose of adjusting the distance between the evaporator and the condenser. Furthermore, the movement of the evaporator will not adversely affect other components inside the dehumidifier.

[0012] Optionally, the linkage drive assembly includes a fixed plate mounted on a base frame. A motor is mounted on one side of the fixed plate, and the output shaft of the motor passes through the fixed plate and is connected to an active linkage mounted on the other side of the fixed plate. Several driven linkages connected end to end are connected to both ends of the active linkage. A connecting block is hinged to the end of the driven linkage, and the connecting block is connected to the first sliding rod.

[0013] Optionally, the driven link has an outwardly protruding limiting pin at its middle position, and the surface of the fixed plate has a plurality of strip holes that match the limiting pin. The length direction of the strip holes is consistent with the length direction of the fixed plate. The limiting pin is placed in the strip holes and can move and rotate within the strip holes.

[0014] By adopting the above technical solution, after the motor starts, the active connecting rod can rotate, which drives multiple driven connecting rods at both ends to rotate. Finally, the movable connecting rod at the far end can drive the connecting block to move, and then drive the first sliding rod to move, thereby achieving the purpose of moving the evaporator. This connecting rod drive assembly can reduce its space occupation inside the dehumidifier and has the advantages of simple structure and stable driving effect.

[0015] Optionally, the condenser is movably mounted on a base frame.

[0016] 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, along with the evaporator's own mobility, can prevent the evaporator from damaging the condenser during movement, allowing the condenser to move a certain distance and providing a safe buffering effect.

[0017] Optionally, the condenser is equipped with a plurality of second sliding rods, and the base frame is equipped with a second guide housing that matches the second sliding rods. The second sliding rods are slidably connected in the channel formed by the second guide housing and the base frame. A spring is installed at the end of the second sliding rod. The spring is sleeved on the outer diameter of the cylindrical boss extending horizontally outward on the side of the base, and one end abuts against the second sliding rod and the other end abuts against the base frame.

[0018] By adopting the above technical solution, the condenser achieves movement within the structure of the second sliding rod and the second guide housing. When the condenser moves to its limit position, it can contact the base frame via a spring, preventing impact between the condenser and the base frame. This prevents damage to the condenser during evaporator movement and also avoids damage caused by the condenser colliding with the base frame during its movement.

[0019] Optionally, temperature sensors are installed on both the evaporator and the condenser.

[0020] By adopting the above technical solution, the temperature of the evaporator and condenser can be detected in real time during actual operation, thus providing a basis for whether the distance between the evaporator and condenser needs to be adjusted, ultimately ensuring that the dehumidifier always operates stably with good dehumidification capacity and effect.

[0021] Optionally, the base frame includes a lower frame located below the evaporator and condenser, and an upper frame located near the condenser, with the upper frame and lower frame connected to each other.

[0022] By adopting the above technical solution, the base frame is designed as a detachable connection structure to facilitate the assembly of the internal structure of the dehumidifier and subsequent maintenance.

[0023] Optionally, it also includes copper tubes connected to the evaporator and condenser respectively, the copper tubes being bent in the middle to form at least one U-shaped structure.

[0024] By adopting the above technical solution, the problem of damage to the copper tubes themselves can be avoided during the movement of the evaporator and condenser.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] This utility model has a simple and ingenious design structure, which can change the distance between the evaporator and condenser according to the ambient temperature and the operating conditions of the equipment during operation, so as to meet the purpose of normal equipment operation.

[0027] When the ambient temperature is low, dehumidifiers are prone to frost or ice buildup on the evaporator surface during operation. In this case, reducing the distance between the evaporator and condenser allows the evaporator to be closer to the condenser. The heat dissipated by the condenser acts on the evaporator surface, which can quickly achieve the effect of defrosting and de-icing. This helps the dehumidifier to dehumidify smoothly even under low temperature conditions and avoids the phenomenon of reduced dehumidification capacity.

[0028] When the ambient temperature is high, the condenser cannot dissipate heat quickly, which will lead to an increase in the compressor load. At this time, reducing the distance between the evaporator and the condenser allows the cold air dissipated by the evaporator to form a heat exchange with the condenser, thereby improving the heat dissipation effect of the condenser and keeping the compressor load stable. This solves the problem of large vibration, high noise, or even shutdown of the compressor due to high load under high temperature conditions. Attached Figure Description

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] As shown in the figure, this application discloses a movable dehumidification component, including a base frame. The base frame includes a lower frame 2 located below the evaporator 3 and the condenser 4, and an upper frame 1 located near the condenser 4. The upper frame 1 and the lower frame 2 are connected to each other.

[0040] The base frame is equipped with a relatively movable evaporator 3 and condenser 4. When the distance between the evaporator 3 and condenser 4 is reduced, the heat exchange efficiency between the evaporator 3 and condenser 4 can be improved, thereby quickly melting the frost or ice on the evaporator 3, achieving the effect of low-temperature dehumidification and increasing the low-temperature dehumidification capacity. The structures of the evaporator 3 and condenser 4 are conventional settings in the prior art and will not be described in detail here.

[0041] In this embodiment, the evaporator 3 is movably mounted on a base frame, and a drive mechanism for moving the evaporator 3 is mounted on the base frame.

[0042] Specifically, the driving mechanism includes a plurality of first sliding rods 12 mounted on the evaporator 3. The length directions of the plurality of first sliding rods 12 are arranged parallel to each other. In this example, there are four first sliding rods 12, which are respectively mounted at the four corners of the evaporator 3 to achieve a smooth effect during the movement of the evaporator 3.

[0043] It also includes a first guide housing 11 mounted on a base frame, and a first sliding rod 12 installed in the channel formed by the first guide housing 11 and the base frame. The first guide housing 11 has a U-shaped cross-section, and the first sliding rod 12 is located in the U-shaped groove of the U-shaped structure. The first guide housing 11 and the base frame limit the movement of the first sliding rod 12, so that the first sliding rod 12 only has the freedom to move back and forth. More specifically, in order to limit the stroke of the first sliding rod 12, a rectangular window 1201 is provided on the first sliding rod 12. A small diameter bolt is used to pass through the rectangular window 1201 and connect to the base frame, thereby limiting the forward and backward stroke of the first sliding rod 12.

[0044] A linkage drive assembly for driving the first sliding rod 12 to move is installed on the first sliding rod 12.

[0045] The linkage drive assembly includes two fixed plates 7 mounted on a base frame, one on the left and one on the right. Mounting holes 701 are provided on the base frame, and the fixed plates 7 are connected to the base frame by bolts. A motor 6 is mounted on one side of the fixed plate 7. The output shaft of the motor 6 passes through the fixed plate 7 and is connected to an active linkage 8 mounted on the other side of the fixed plate 7. Several driven linkages 9 are connected end-to-end at both ends of the active linkage 8. A connecting block 10 is hinged to the end of each driven linkage 9. The connecting block 10 is connected to a first sliding rod 12. The end of the driven linkage 9 is inserted into an elongated hole in the connecting block 10 via a pin, allowing the pin to slide and rotate within the elongated hole when the end of the driven linkage 9 swings.

[0046] Specifically, the driven link 9 has an outwardly protruding limiting pin 901 at its middle position. The surface of the fixed plate 7 has multiple strip holes 702 that match the limiting pin 901. The length direction of the strip holes 702 is consistent with the length direction of the fixed plate 7. The limiting pin 901 is placed in the strip holes 702 and can move and rotate within the strip holes 702. In specific operation, the motor 6 drives the active link 8 to rotate, and the active link 8 then drives the driven link 9 to swing. When the active link 8 rotates from the inclined direction to the vertical direction, the driven link 9 at the end can move the connecting block 10, the first sliding rod 12 and the evaporator 3 toward the direction closer to the condenser 4, thereby reducing the gap between the evaporator 3 and the condenser 4. Conversely, the gap between the evaporator 3 and the condenser 4 increases.

[0047] In this example, the condenser 4 is movably mounted on the base frame.

[0048] Specifically, the condenser 4 is equipped with a plurality of second sliding rods 15, and the base frame is equipped with a second guide housing 14 that matches the second sliding rods 15. The second sliding rods 15 are slidably connected in the channel formed by the second guide housing 14 and the base frame. A spring 16 is installed at the end of the second sliding rod 15. The spring 16 is sleeved on the outer diameter of the cylindrical boss 201 extending horizontally outward on the side of the base, and one end abuts against the second sliding rod 15 and the other end abuts against the base frame.

[0049] In this example, there are also four second sliding rods 15, which are installed at the four corners of the condenser 4 to ensure smooth movement of the condenser 4. Similar to the structure of the first guide housing 11, the cross-section of the second guide housing 14 is also U-shaped. The second sliding rods 15 are placed in the U-shaped groove of the U-shaped structure. The second sliding rods 15 only have the freedom of movement in the forward and backward directions. Similarly, in order to limit the forward and backward travel of the second sliding rods 15, a circular hole 1501 is provided on the second sliding rods 15. A bolt smaller than the circular hole 1501 is inserted and the bolt is installed. Mounted on the base frame (lower frame 2 in this example), the second sliding rod 15 can be moved slightly. When working, the evaporator 3 moves towards the condenser 4. Since ice will form on the surface of the evaporator 3, the initial distance between the evaporator 3 and the condenser 4 can be reduced. When the evaporator 3 moves, it will hit the condenser 4. By setting the condenser 4 to a movable structure, the condenser 4 can move slightly when the evaporator 3 comes into contact with the condenser 4, avoiding damage to the evaporator 3 or the condenser 4 due to the impact, which helps to extend the service life of both.

[0050] Specifically, temperature sensors 13 are installed on both the evaporator 3 and the condenser 4. The two temperature sensors 13 are used to monitor the real-time temperature of the evaporator 3 and the condenser 4 during operation. They can provide feedback on the temperature of the equipment under different operating conditions, thereby reflecting the load of the equipment compressor. This allows the equipment controller to adjust the distance between the evaporator 3 and the condenser 4 in real time, so that the compressor load remains relatively balanced.

[0051] Specifically, it also includes copper pipes 5 connected to the evaporator 3 and the condenser 4 respectively. The copper pipes 5 are bent in the middle to form at least one U-shaped structure. More specifically, in this embodiment, soft copper pipes 5 can be selected to cooperate with the movement of the evaporator 3 and the condenser 4 and avoid damage to the copper pipes 5.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
