Description

Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to a silent dehumidifier. Background Technology

[0002] Some groups are particularly sensitive to sound; this sensitivity (sometimes called auditory hypersensitivity) can make ordinary ambient sounds feel like unpleasant or even painful stimuli. This is especially challenging at night, as the brain becomes more alert during sleep preparation. This isn't a personality flaw, but a physiological peculiarity, and such individuals prioritize quiet operation when choosing home appliances. Dehumidifiers are often placed in bedrooms, so reducing their noise is also crucial. The noise from a dehumidifier primarily comes from the fan and compressor; reducing the noise of these two components will achieve a quiet operation.

[0003] In the humid south, floors and walls condense large amounts of water droplets, especially in ground-floor apartments and basements where dampness is more severe. If dehumidification is not carried out promptly, mold may grow or walls may be damaged, leading to serious consequences. Furthermore, the energy consumption of dehumidifiers affects their market competitiveness; making dehumidifiers more energy-efficient is a major research direction. In recent years, the concept of a "five-constant ecological air conditioning system" has been proposed, requiring systems that meet five requirements: constant temperature, constant humidity, constant oxygen, constant quietness, and constant cleanliness. For dehumidifiers, at least three of these requirements must be met to align with mainstream trends. Additionally, with increasing emphasis on environmental protection, energy conservation is also a major research direction for dehumidifiers.

[0004] Korean Patent Publication No. KR101759520B1, entitled "Space-Saving, Noise-Free Dehumidifier with Natural Convection Operation Without Heater," discloses a dehumidifier that eliminates the fan, replacing its forced convection with natural convection through an expanded copper plate, thus eliminating noise. This space-saving, noise-free dehumidifier eliminates the main source of noise and dehumidifier malfunctions by removing the fan that draws in and out of the room. The chimney duct element achieves dehumidification through natural convection, and its long, integrated structure against the wall facilitates efficient space utilization. However, this design has some drawbacks. The heating element is located high, while the cooling element is low. While this allows for natural convection outdoors, it's impossible to open windows for ventilation while the dehumidifier is operating, as the high humidity from outdoors would prevent the humidity from decreasing. In a closed environment, this dehumidifier will cause warmer air to accumulate at the top and cooler air to accumulate at the bottom, creating a temperature difference. This weakens the natural convection, hindering efficient dehumidification. The core function of a dehumidifier is dehumidification, requiring a larger refrigeration structure. However, this contradicts the tubular convection structure, which necessitates increased heating area and length. Otherwise, air cannot rise (heated air, with its lower density, rises, while cooled air, with its higher density, flows downwards). Since the refrigeration and heating structures are housed in the same duct, this contradiction is inevitable. Judging from the patent drawings, the engineers sacrificed the heat exchange area of ​​the refrigeration structure to achieve natural convection, resulting in poor dehumidification, high energy consumption, and an inability to achieve energy savings. Summary of the Invention

[0005] This application provides a silent dehumidifier to at least solve the noise problems existing in the prior art.

[0006] According to this application, a silent dehumidifier is provided, including an evaporator, a collector, a condenser, a compressor, a throttling element, and connecting pipes. The evaporator, condenser, compressor, and throttling element are connected by the connecting pipes. The evaporator is fixedly installed on the first side of the indoor wall. The evaporator includes an evaporator tube and a temperature guide plate. The temperature guide plate is fixedly installed on the side of the evaporator tube away from the wall. The temperature guide plate covers at least part of the wall. The collector is located below the temperature guide plate and is used to collect water droplets condensed and falling from the temperature guide plate.

[0007] Alternatively, the evaporator can be fixedly installed under the floor or roof of the room. A heat-conducting plate is installed below the evaporator. The heat-conducting plate is partially or entirely tilted at a certain angle so that the condensate can slide down the heat-conducting plate to a lower position. A collector is located below the heat-conducting plate to collect the water droplets that condense and fall from the heat-conducting plate.

[0008] Compared with existing technologies, the silent dehumidifier of this application has the following advantages:

[0009] The silent dehumidifier of this application eliminates the need for a fan, achieving both energy savings and quiet operation, meaning it produces virtually no noise during operation. The evaporator is positioned on the wall or floor, with the heat-conducting plate serving as either a wall panel or ceiling. Being relatively high above the ground, it allows for airflow entirely through natural convection. Since water vapor is less dense than air, there is relatively more water vapor at higher points in the room. In other words, the higher the condenser is positioned, the better the dehumidification effect through natural convection. The refrigerant lowers the temperature of the heat-conducting plate, causing some water vapor in the indoor air to condense upon contact with the plate. As the air temperature decreases, its density increases, allowing it to fall naturally, thus achieving natural convection and resulting in energy savings.

[0010] Of course, the technical solution of this application does not preclude the use of fans. In situations with high humidity and when rapid dehumidification is needed, a fan can be used to blow air onto the temperature guide plate, which can greatly improve the dehumidification speed. However, this will generate some noise, and people with rhinitis and infants are more resistant to fans. Natural convection dehumidification is the healthiest and more energy-efficient and environmentally friendly method. If aesthetics are not a concern, the temperature guide plate can be made into a finned structure to increase the heat absorption effect of the evaporator, but the cost will also be higher. If the temperature guide plate is made into a flat plate structure, its heat absorption area can cover the entire wall, which is sufficient for use when the dehumidification power is relatively low.

[0011] In one embodiment, at least a portion of the heat-conducting plate is installed on a first inclined plane and a second inclined plane. The first inclined plane forms a certain angle with the horizontal plane, and the second inclined plane also forms a certain angle with the horizontal plane. The angle between the first and second inclined planes is such that they intersect at a first edge. The first edge forms a certain angle with the horizontal plane, and the collector is installed at the lowest point of the first edge. This facilitates condensate collection. If the heat-conducting plate is completely installed on the first and second inclined planes, condensate can be collected at a single location. More inclined planes can also be used. If the inclined plane is an inverted pyramid, condensate can also be collected at a single location. Alternatively, a conical surface can also be used to collect condensate at a single location. Different structures have different visual effects, but all achieve the goal of collecting condensate at the same location.

[0012] In one embodiment, the temperature-conducting plate is coated with a hydrophobic coating or covered with a hydrophobic film, or is made of a hydrophobic material. This facilitates the flow and collection of condensate, preventing condensate from adhering to the temperature-conducting plate and evaporating again, as well as preventing mold growth caused by high humidity on the temperature-conducting plate after the dehumidifier is turned off.

[0013] In one embodiment, the evaporator is provided with a heat insulation layer on the side closest to the wall, and the compressor is located inside the wall or on the second side of the wall. The compressor is isolated from the room by the heat insulation layer. Heat insulation materials generally have a certain sound insulation effect. The compressor is quite noisy when it is working, so setting up a heat insulation layer not only has an energy-saving effect, but also reduces noise.

[0014] In one embodiment, the condenser is positioned diagonally below or directly below the evaporator, with a floor or tiles covering the top and an insulation layer below. Vertical convection is most efficient, meaning the condenser is positioned at the highest point in the room and the evaporator at the lowest. However, for ease of installation, the evaporator can also be installed on the wall and the condenser under the floor, facilitating condensate collection.

[0015] In one possible implementation, the condenser is positioned directly below the evaporator and on the first side of the interior wall. A heat-conducting plate is located on the side of the condenser away from the wall, and the heat-conducting plate at least partially covers the wall. For some older houses with existing floors, removing the floors would be costly; therefore, placing the condenser on the wall can be considered, as it also provides good convection.

[0016] In one embodiment, the condenser and evaporator are arranged adjacent to or opposite each other, and are located on the first side of an indoor wall. A heat-conducting plate is provided on the side of the condenser away from the wall, and the heat-conducting plate is arranged parallel to or at a certain angle to the temperature-conducting plate. For some older houses with existing floors, removing the floors is costly; therefore, placing the condenser on the wall can be considered, which also provides good convection. The condenser and evaporator can be installed on different walls, on the same wall, or on opposite walls.

[0017] In one embodiment, a deflector is provided on the side of the heat-conducting plate away from the wall, and the deflector extends upward at an angle. This prevents hot air from rising along the wall, directing it away from the wall as much as possible and drawing air from a distance into the circulating airflow, resulting in better dehumidification.

[0018] In one embodiment, the compressor is located outdoors, and a heat exchanger is installed outdoors. The heat exchanger is connected in parallel with the condenser or the evaporator, enabling indoor temperature regulation through pipeline switching. While air conditioning dehumidifies and lowers the air temperature, existing dehumidifiers cannot regulate air temperature. However, by adding a heat exchanger to replace the evaporator or condenser, heating or cooling functions can be achieved. With the increasing prevalence of five-constant systems (constant temperature, constant humidity, and constant noise), future environmental requirements will be higher, necessitating multi-functional dehumidifiers. Single-function dehumidifiers are easily eliminated by the market; multi-functional combinations can meet the demands for quality of life. The technical solution of this application satisfies the three major requirements of constant temperature, constant humidity, and constant quietness, fully meeting the needs of villa areas or mountainous regions with good environments.

[0019] In one embodiment, the connecting pipes at both ends of the evaporator are equipped with a first three-way valve and a second three-way valve, which are connected to both ends of the heat exchanger via connecting pipes. The connecting pipes at both ends of the condenser are equipped with a third three-way valve and a fourth three-way valve, which are connected to both ends of the heat exchanger via connecting pipes. In the first operating mode, the evaporator is in operation when connected to the circulation pipe via the first and second three-way valves, and the condenser is in operation when connected to the circulation pipe via the third and fourth three-way valves. The heat exchanger is not connected to the circulation pipe. In the first operating mode, the evaporator is connected to the circulation pipeline and is in a resting state. In the second operating mode, the evaporator is connected to the circulation pipeline through the first and second three-way valves and is in operation. The heat exchanger is connected to the circulation pipeline through the third and fourth three-way valves and is in operation. The condenser is not connected to the circulation pipeline and is in a resting state. In the third operating mode, the heat exchanger is connected to the circulation pipeline through the first and second three-way valves and is in operation. The condenser is connected to the circulation pipeline through the third and fourth three-way valves and is in operation. The evaporator is not connected to the circulation pipeline and is in a resting state. The first operating mode is the dehumidification mode, the second mode is the cooling mode, and the third mode is the heating mode. The cooling and heating modes can adjust the temperature, and the dehumidification mode can adjust the humidity. For dry northern regions, a humidifier can also be used to increase the air humidity. This application does not use a fan and places the compressor outdoors, so the operating noise is very low, and constant temperature, constant humidity, and constant quiet operation can be achieved.

[0040] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] like Figure 1 and Figure 2 As shown, a silent dehumidifier includes an evaporator 1, a collector 2, a condenser 3, a compressor 4, a throttling element 5, and connecting pipes 6. The evaporator 1, condenser 3, compressor 4, and throttling element 5 are connected by connecting pipes 6 to form a heat exchange system. Specifically, the compressor 4 first delivers compressed refrigerant to the condenser 3 for cooling and liquefaction. After throttling by the throttling element 5, the refrigerant reaches the evaporator 1, where it absorbs heat and vaporizes. It then passes through a gas-liquid separator 65 before re-entering the compressor 4. For ease of control and connection, connecting pipes 6 can be equipped with multiple one-way valves 7, solenoid valves 8, and expansion valves as needed. The arrows in each figure indicate the direction of natural air convection.

[0042] Example 1:

[0043] like Figure 1 and Figure 2As shown, the evaporator 1 is fixedly installed on the first side of the indoor wall 9. The evaporator 1 includes an evaporator tube 10 and a temperature guide plate 11. The temperature guide plate 11 is fixedly installed on the side of the evaporator tube 10 away from the wall 9, and the temperature guide plate 11 covers at least part of the wall 9. The collector 2 is located below the temperature guide plate 11 and is used to collect the water droplets condensed and falling from the temperature guide plate 11. The temperature guide plate 11 is made of aluminum alloy, which can increase its thermal conductivity. If cost is not a concern, it can also be made of copper sheet, which has better thermal conductivity. To ensure the dehumidification efficiency and aesthetics of the room, the temperature guide plate 11 is parallel to the wall 9 and covers the entire wall 9. The temperature guide plate 11 can be used as a wall panel. The installation position of the temperature guide plate 11 can be reserved during the decoration of the unfinished house, which can save decoration costs and reduce the installation cost of the dehumidifier.

[0044] In one embodiment, the heat-conducting plate 11 is coated with a hydrophobic coating or covered with a hydrophobic film, or is made of a hydrophobic material. This creates a superhydrophobic surface on the heat-conducting plate 11, with a contact angle with water droplets >150°, allowing water droplets to easily roll off without leaving residue. The chemical composition of the hydrophobic coating causes it to form a low surface energy film after curing. Water has a high surface tension and tends to bind with its own molecules (forming water droplets) rather than with molecules of materials with low surface energy. This ensures that water droplets do not accumulate on the surface of the heat-conducting plate 11, much like water droplets cannot "grasp" the surface of a lotus leaf and instead clump together. Hydrophobic coatings include silicone resin-based coatings, PTFE / PFA / EP-based composite coatings, and graphene-based infrared radiation heat dissipation coatings; the covering hydrophobic film is a polyurethane-based composite film.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the heat-conducting plate 11 includes a main plate 12, a left wing plate 13, and a right wing plate 14. The left wing plate 13 and the right wing plate 14 are located on both sides of the main plate 12 and are perpendicular to the main plate 12. The thickness of the heat-conducting plate 11 is 0.5mm-2mm, the width of the main plate 12 is 200mm-600mm, the length of the main plate 12 is between 600mm-2400mm, and the width of the left wing plate 13 and the right wing plate 14 is between 10mm-30mm. Multiple heat-conducting plates 11 can be spliced ​​together in the longitudinal direction to form a heat exchange plane or curved surface. The splicing structure facilitates transportation. For aesthetic purposes, a single heat-conducting plate can also be used. To avoid interference with the evaporator tube 10, the left wing plate 13 and the right wing plate 14 are provided with through grooves 60 at the intersection with the evaporator tube 10.

[0046] like Figure 3 and Figure 4As shown, a support block 17 is provided on the back of the main board 12. The support block 17 has a mounting groove 16, and the evaporator tube 10 can be engaged in the mounting groove 16. The support block 17 can be made of aluminum to increase thermal conductivity. The support block 17 and the main board 12 can be directly welded or snapped together. If a detachable connection is used, thermal grease is applied to the connection area to increase thermal conductivity. The upper and lower ends of the left wing plate 13 and the right wing plate 14 are beveled to facilitate insertion and installation. A transition plate 15 is provided at the upper end of the main board 12. The transition plate 15 is located on a different plane from the main board 12. When adjacent temperature-conducting plates 11 are connected, the transition plate 15 is used to achieve a transition, preventing condensate from entering the inner side of the temperature-conducting plate 11.

[0047] like Figure 1 and Figure 6 As shown, in one embodiment, the evaporator 1 is provided with a heat insulation layer 18 on the side near the wall 9, and a compressor 4 is provided on the second side of the wall 9. The compressor 4 can be installed on the wall 9 by a bracket. The compressor 4 is isolated from the room by the heat insulation layer 18. The heat insulation layer 18 can be made of cork and has a certain sound insulation effect.

[0048] like Figure 6 and Figure 7 As shown, to enhance the heat transfer performance between the temperature-conducting plate 11 and the evaporator tube 10, the evaporator tube 10 is made into a flat tube. The evaporator tube 10 can be directly welded to the connecting pipe 6, or a conversion connector can be manufactured for connection. The evaporator tube 10 is mounted to the wall 9 using a clamping seat 19. The clamping seat 19 has a snap-fit ​​groove 20 that engages with the evaporator tube 10. The clamping seat 19 is mounted to the wall 9 using expansion screws. The wall 9 also has multiple clamping strips 91, each with a left clamping plate 92 and a right clamping plate 93 that have a certain degree of elasticity. The left wing plate 13 and right wing plate 14 of adjacent temperature-conducting plates 11 can be inserted between the left clamping plate 92 and the right clamping plate 93 of the same clamping strip 91, resulting in a flatter and more stable installation of the temperature-conducting plates 11. The clamping seat 19 is made of a heat-insulating or low-thermal-conductivity material.

[0049] like Figure 1 As shown, in one possible embodiment, the condenser 3 is positioned directly below the evaporator 1 and on the first side of the indoor wall 9. A heat-conducting plate 31 is provided on the side of the condenser 3 away from the wall 9, and the heat-conducting plate 31 at least partially covers the wall 9. The condenser 3 also includes a condenser tube 32, which can also be fixed to the wall 9 via a mounting bracket 19. The heat-conducting plate 31 can also be fixed to the condenser tube 32 via a support block 17. The heat-conducting plate 31 and the heat-conducting plate 11 can have the same structure and be installed in the same manner.

[0050] like Figure 1 and Figure 6As shown, in one embodiment, a guide plate 33 is provided on the side of the heat-conducting plate 31 away from the wall 9, and the guide plate 33 extends upward at an angle. The guide plate 33 can be designed as a curved arc or a flat structure, and is installed on the heat-conducting plate 31 through a guide seat 34. The guide plate 33 will occupy a certain amount of room space. Alternatively, a suspended table can be fixed to the wall 9 or the heat-conducting plate 31. The table has the function of guiding airflow, and objects can be placed on the tabletop. Hot air can rise around the tabletop to achieve natural convection.

[0051] like Figure 1 and Figure 8 As shown, the collector 2 has a horizontally extending water collection tank 21, which is located at the bottom of the temperature guiding plate 11. The water collection tank 21 is inclined at a certain angle relative to the horizontal plane, with an inclination angle of at least 3°, so that the condensate can automatically flow to one side. The front side of the water collection tank 21 is provided with a front wing plate 22, which is inclined upward to collect water droplets falling from the temperature guiding plate 11. The bottom of the water collection tank 21 is provided with a guide pipe 23, which can guide the condensate to the outside or to the sewer pipe. Alternatively, a water tank can be installed to collect the condensate.

[0052] Example 2:

[0053] like Figure 10 As shown, the difference from Embodiment 1 is that the compressor 4 is installed inside the wall 9, close to the condenser 3, and connected to the evaporator 1 via connecting pipe 6. Installing the condenser 3 in the wall 9 prevents moisture buildup on the wall 9.

[0054] like Figure 10 As shown, in one possible embodiment, the condenser 3 and the evaporator 1 are arranged adjacent to each other and perpendicular to each other, and are located on the first side of the indoor wall 9. A heat-conducting plate 31 is provided on the side of the condenser 3 away from the wall 9, and the heat-conducting plate 31 and the temperature-conducting plate 11 are arranged perpendicular to each other. In another possible embodiment, the heat-conducting plate 31 and the temperature-conducting plate 11 are arranged parallel to each other, that is, the condenser 3 and the evaporator 1 are arranged opposite each other, the air near the condenser 3 sinks, and the air near the evaporator 1 rises.

[0055] Example 3:

[0056] like Figure 11 As shown, the evaporator 1 is installed on the wall 9. The difference from Embodiment 1 is that the condenser 3 is located on the ground diagonally below the evaporator 1. The condenser 3 is covered with a floor 30 or floor tiles, and an insulation layer is installed below the condenser 3 to prevent heat loss. This solution is preferred when the room does not have a floor 30 installed, as it is convenient to install and has a lower cost. Additionally, heating the floor prevents dampness and quickly evaporates moisture from the floor 30.

[0057] Example 4:

[0058] like Figure 11and Figure 12 As shown, in one embodiment, the condenser 3 is positioned directly below the evaporator 1, and the condenser 3 is covered by a floor 30 or floor tiles. The evaporator 1 is fixedly installed under the indoor floor slab 24 or roof. A temperature-conducting plate 11 is provided below the evaporator 1, and the temperature-conducting plate 11 is partially or entirely tilted at a certain angle so that condensate can slide down the temperature-conducting plate 11 to a lower position. A collector 2 is located below the temperature-conducting plate 11 to collect the water droplets condensed and falling from the temperature-conducting plate 11. The evaporator 1 can be installed using the mounting bracket 19 and mounting strip 91 as shown in Embodiment 1.

[0059] In one embodiment, at least a portion of the temperature-conducting plate 11 is installed on a first inclined surface 25 and a second inclined surface 26. The first inclined surface 25 extends downwards towards the second inclined surface 26 at a certain angle to the horizontal plane. The second inclined surface 26 extends downwards towards the first inclined surface 25 at a certain angle to the horizontal plane, with the angle being greater than or equal to 3°. The angle between the first inclined surface 25 and the second inclined surface 26 is such that they intersect at a first edge 27. The first edge 27 is located at a lower position and forms an angle with the horizontal plane greater than or equal to 5°. A collector 2 is installed at the lowest position of the first edge 27. The condensate from the first inclined surface 25 and the second inclined surface 26 can collect in the collector under gravity. The collector 2 is equipped with a drain pipe to drain the condensate. The temperature-conducting plate 11 can be configured as a conical surface or a prism surface; different styles achieve the same function.

[0060] Example 5:

[0061] like Figure 14 As shown, the evaporator 1 can be installed on the roof using the installation method of embodiment 4, while the condenser 3 is installed below the floor 30. The compressor 4 is located outdoors, and a heat exchanger 41 is provided outdoors. The heat exchanger 41 is connected in parallel with the condenser 3 or in parallel with the evaporator 1, so that the indoor temperature can be regulated by switching the pipeline. The heat exchanger 41 achieves efficient heat exchange through the axial fan 42. The heat exchanger 41 can replace the evaporator 1 or the condenser 3 for cooling or heating.

[0062] like Figure 14As shown, the evaporator pipe 10 includes a main pipe 28 and branch pipes 29. Multiple branch pipes 29 are connected in parallel and then in series with the main pipe 28. Each branch pipe 29 can be equipped with an individual solenoid valve 8 for control. The temperature guide plate 11 is equipped with multiple temperature sensors to monitor the temperature near different branch pipes 29. In areas with lower air temperature, the solenoid valve 8 of the branch pipe 29 is closed, and in areas with higher air temperature, the solenoid valve 8 is open. This reduces the power of the compressor 4, lowers energy consumption, and achieves energy saving. The dehumidifier can be equipped with a humidity detection device. Humidity changes are usually slow, so it can operate at low power when the humidity is below 70%, stop operating when the humidity is below 60% and the temperature is below 10℃, and also stop operating when the humidity is below 50% and the temperature is below 30℃. It can run continuously for 24 hours when the humidity is above 70%, and uses a fan for auxiliary dehumidification when the humidity is above 90%.

[0063] like Figure 14 and Figure 15 As shown, in one embodiment, the connecting pipes 6 at both ends of the evaporator 1 are equipped with a first three-way valve 61 and a second three-way valve 62. The first three-way valve 61 and the second three-way valve 62 are connected to both ends of the heat exchanger 41 through the connecting pipes 6. The connecting pipes 6 at both ends of the condenser 3 are equipped with a third three-way valve 63 and a fourth three-way valve 64.

[0064] In recent years, five-constant systems have become popular. For suburban areas and areas with good air quality, constant temperature, constant humidity, and constant quietness are sufficient. In special cases such as high humidity, a fan can be used to deliver air to the temperature guide plate 11, which greatly increases the dehumidification effect. To ensure more uniform condensation on the temperature guide plate 11 at each location, a three-dimensional oscillating fan can be used to blow air onto different locations in sequence. In addition, temperature sensors can be installed at each location. In areas with lower temperatures, more fans can be used to raise the temperature and improve dehumidification efficiency.
