Description

Technical Field

[0001] The invention relates to the technical field of air humidity regulation, and in particular to a box-type heat pump dehumidifier. Background Art

[0002] With the rapid development of science and technology and the rapid economic growth, humidity control in logistics and warehousing has become an urgent problem to be solved. In the humid season of spring and early summer, the impact in the dry north may not be significant, but in the south, the goods are obviously affected by the humid weather, especially paper products and electronic products that have extremely high humidity requirements.

[0003] At present, the heat pump dehumidifiers on the market are usually of upper and lower structures, with the upper part consisting of evaporator, condenser, fan, etc., and the lower part consisting of compressor. The upper and lower structures are loosely arranged and the space is not fully utilized. For this reason, the patent with publication number CN215675552U provides a box-type heat pump dehumidifier. Although it solves the layout problem, it directly uses the evaporator to precipitate the moisture in the air by cooling it down, and then heats the condenser. This method is suitable for the situation where the air temperature is relatively high. Once the temperature is relatively low, the absolute humidity of the air is not high, which will cause the proportion of gaseous water in the air to be not high, so that the amount of moisture precipitated through the evaporator within a certain period of time is not as good as that in the case where the air temperature is relatively high, and the dehumidification efficiency needs to be improved.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0005] The purpose of the present invention is to design a single-layer structure that can quickly dehumidify an indoor environment with a lower temperature and improve the dehumidification efficiency to solve the above-mentioned deficiencies in the technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a box-type heat pump dehumidifier, comprising a box body, one end of the box body having an air inlet, the other end having a first air outlet, an evaporator, a condenser, a compressor and a fan are installed in the box body, the box body is in a long cylindrical shape as a whole, the condenser is installed in the box body at one end close to the air inlet, the compressor and the fan are installed in the box body at one end close to the first air outlet, the evaporator is installed in the middle of the box body, a water collecting box located at the bottom of the evaporator is also slidably installed in the box body, a side wall of the box body between the evaporator and the condenser is provided with a plurality of second air outlets, the second air outlets are close to the evaporator, and a metal regulating member is slidably connected to one end of the box body close to the air inlet;

[0007] When the metal regulating piece blocks the second air outlet, the air is initially heated between the metal regulating piece and the outer wall of the box, and then passes through the air inlet and is heated again by the working condenser. The absolute humidity of the heated air increases, and it can accommodate more gaseous water. After being cooled by the evaporator, the precipitated water droplets flow into the water collecting box to form low-temperature and low-humidity gas, and then the fan and compressor absorb heat to form high-temperature and low-humidity gas to be discharged, which is used to absorb gaseous water in the air.

[0008] When the metal regulating piece blocks the air inlet, the fan is started to reverse and air is sucked in from the first air outlet, and low-temperature and low-humidity gas is discharged through the evaporator and the second air outlet to reduce the ambient temperature.

[0009] Preferably, the metal regulating part includes a sealing plate slidably connected to the outside of the box body, a plurality of equidistantly distributed first grid plates fixedly connected to the outer wall of the sealing plate, an outer cover fixed together at the middle parts of the plurality of first grid plates, and an end plate fixedly installed at one end of the outer cover away from the evaporator, an air inlet channel is formed between the outer cover and the sealing plate, the sealing plate matches the shape of the second air inlet, and the air inlet matches the shape of the end plate.

[0010] Preferably, a limit strip is fixedly installed on the outer wall of the box body adjacent to one side of the second air outlet, and when the limit strip is in contact with the side wall of the blocking plate, the blocking plate blocks the second air outlet.

[0011] Preferably, the cross section of the middle portion of the box body is smaller than the cross sections at the two ends, forming a cooling channel, the evaporator is installed in the cooling channel, and the two ends of the box body form a heating channel.

[0012] Preferably, a plurality of equally spaced second grid plates are fixedly mounted on the outer wall of the box at one end of the first air outlet, and the first grid plate and the second grid plate transfer heat to the air at both ends of the box through heat transfer. The middle part of the box reduces the temperature of the surrounding air in the middle part of the box through heat transfer, and the hot air rises while the cold air falls. The air inlet channel in the first grid plate draws in the surrounding hot air mixed with cold air to form a circulating airflow in the room.

[0013] Preferably, the length of the cooling channel is the sum of the lengths of the two heating channels, and the fan and the condenser are respectively located at the ends of the two heating channels.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0015] 1. This device blocks the second air outlet or air inlet through a metal regulating piece, and cooperates with the forward and reverse rotation of the fan, so that the indoor humid air will first be heated up to remove the saturated gaseous water to form high-temperature and low-humidity air, and then the gaseous water will be further removed while cooling to form low-temperature and low-humidity air, which dehumidifies the indoor air and regulates the temperature at the same time;

[0016] 2. This dehumidifier heats up the inhaled air in advance, and its absolute humidity is increased, so it can accommodate more gaseous water, absorb moisture in the air, and continue to heat up when passing through the condenser to increase its absolute humidity. When it passes through the evaporator, more water can be precipitated and dripped into the water collection box at the same time compared with the existing technology, thereby improving its dehumidification efficiency;

[0017] 3. Compared with the common double-layer design in the prior art, this dehumidifier has a more compact layout, fully utilizes the space, and can also cool the fan and compressor during operation, thereby increasing their service life;

[0018] 4. The cross-sectional area of ​​the cooling channel of this dehumidifier is smaller than that of the heating channel, so that the flow rate of air in the heating channel is slowed down, reducing the erosion of the compressor surface by the fast-flowing air.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The present invention provides Figure 1-4 A box-type heat pump dehumidifier shown in the figure comprises a box body 1, one end of the box body 1 has an air inlet 2, and the other end has a first air outlet 3, the box body 1 is in the shape of a long cylinder as a whole, the cross section of the middle part of the box body 1 is smaller than the cross section of the two ends, forming a cooling channel 12, the evaporator 4 is installed in the cooling channel 12, and the two ends of the box body 1 form a heating channel 13, the length of the cooling channel 12 is the sum of the lengths of the two heating channels 13, a condenser 5 is fixedly installed at the end of the heating channel 13 near the air inlet 2, and a fan 7 is fixedly installed at the end of the heating channel 13 near the first air outlet 3, and a compressor 6 is also installed in the same heating channel 13 where the fan 7 is installed, and the connection relationship between the compressor 6, the evaporator 4, and the condenser 5 is a prior art means, which will not be repeated here; the middle part of the box body 1 is located A water collecting box 8 is also slidably mounted at the bottom of the evaporator 4, and a second air outlet 9 is provided on the outer wall of the box body 1 between the condenser 5 and the evaporator 4, and the second air outlet 9 is close to the evaporator 4. A blocking plate 10a is also slidably connected to the outside of the box body 1, and a plurality of equally distributed first grid plates 10b are fixedly connected to the outside of the blocking plate 10a, and an outer cover 10c is fixedly mounted in the middle of the plurality of first grid plates 10b, and an end plate 10d is fixedly mounted at the end of the outer cover 10c, and an air inlet channel 10e is formed between the outer cover 10c, the blocking plate 10a, the outer wall of the box body 1 and the end plate 10d. When the end plate 10d fits with the end of the box body 1 to block the air inlet 2, the blocking plate 10a does not block the second air outlet 9, and when the blocking plate 10a blocks the second air outlet 9, the end plate 10d does not block the air inlet 2;

[0029] The user places the device on the ground, first blocks the second air outlet 9 with the blocking plate 10a, and then starts the dehumidifier. The fan 7, compressor 6 and condenser 5 generate heat when working. This heat will be transferred to the air at both ends of the box 1 through the first grid plate 10b and the second grid plate 14 through heat transfer. The absolute humidity of the air at both ends of the box 1 increases after the temperature is increased, and it can accommodate more gaseous water, that is, under the same volume, the percentage of water vapor contained in it increases, and the air will float up after absorbing heat, and the cold air that has not absorbed heat will sink, and part of the cold air will sink to the middle of the box 1. When the fan 7 is working, the air inlet channel 10e will generate suction to suck in part of the cold air in the middle of the box 1 and the hot air around the first grid plate 10b. The inhaled cold air and hot air are mixed and enter the box from the air inlet 2 The air passes through the condenser 5, absorbs the heat emitted by the condenser 5, and continues to heat up, thereby increasing its absolute humidity again. After passing through the evaporator 4, this part of the high-temperature and high-humidity air precipitates water and drips into the water collecting box 8, forming low-temperature and low-humidity air passing through the compressor 6 and the fan 7. Since the compressor 6 and the fan 7 generate heat when working, the low-temperature and low-humidity air absorbs the heat when passing through. While dissipating the heat of the compressor 6 and the fan 7, high-temperature and low-humidity air is also formed and discharged from the first air outlet 3 to absorb the gaseous water in the indoor air, and cooperates with the air inlet channel 10e to suck air, so that the indoor air forms a circulating airflow with the box 1 as a node, which not only increases the dehumidification range of the product, but also makes the discharged high-temperature and low-humidity gas mix with the indoor air at a faster speed, thereby increasing the speed of absorbing gaseous water, thereby improving the dehumidification effect.

[0030] When the indoor humidity is almost cleared and the room is filled with high-temperature and low-humidity gas, the sealing plate 10a is pushed to no longer seal the second air outlet 9, but the air inlet 2 is sealed with the end plate 10d, and the fan 7 is started to reverse. The fan 7 will suck air from the first air outlet 3 into the box 1, and the air will be cooled by the evaporator 4 after passing through the fan 7 and the compressor 6 to form low-temperature and low-humidity air. Since the second air outlet 9 is close to the evaporator 4, only the low-temperature and low-humidity gas will take away the heat emitted by the condenser 5, and most of it will be discharged directly from the second air outlet 9 and discharged from the box 1 through the air inlet channel 10e to start cooling the indoor air.

[0031] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are exemplary only. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, changes in orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
