Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to an air outlet and guide structure and a dehumidifier. Background Art

[0002] A semiconductor dehumidifier is a new type of dehumidifier that uses semiconductor refrigeration to remove humidity. It primarily utilizes the thermoelectric effect of semiconductor materials to remove humidity. The general operating principle is as follows: when powered on, the semiconductor cooling chip begins to operate, causing one side of the chip to cool, forming the cold end, while the other side to heat, forming the hot end. A fan draws moist air into the unit. Passing over the cold end of the chip, water vapor condenses into water upon cooling and is collected. The dehumidified, cool air continues to flow over the hot end of the chip. There, the air absorbs heat, raising its temperature. Finally, the heated, dry air is exhausted, and this cycle continues, reducing indoor humidity.

[0003] The specification for publication of a Chinese invention patent application (CN107940619A) discloses a high-efficiency semiconductor dehumidifier, comprising a dehumidification main body and an outer shell covering the dehumidification main body. The dehumidification main body comprises an inner shell arranged upright and a semiconductor heat exchange component. The area inside the inner shell forms an air outlet cavity, and the area between the inner shell and the outer shell forms an air inlet cavity. The semiconductor heat exchange component comprises a cooling member distributed in the air inlet cavity, a heat sink distributed in the air outlet cavity, and a semiconductor refrigeration plate located between the cooling member and the heat sink and transferring heat to the cooling member and the heat sink. The outer shell is provided with circumferentially distributed air inlets, and the top of the outer shell is provided with an air outlet corresponding to the air outlet cavity. A fan is provided under the inner shell, and air is sucked in around the dehumidifier and out from the top by the fan.

[0004] However, due to the hollow structure of the inner shell of the aforementioned dehumidifier, air undergoes dehumidification and flows toward the air outlet under the influence of a fan. Some of this air passes through the heat sink, exchanging heat with the fins, while the remaining air exits directly from the hollow portion of the inner shell without passing through the fins. This air outlet method prevents the heat sink from fully exchanging heat with all the exhaust air, hindering its full heat dissipation efficiency. Furthermore, the exhaust air temperature is uneven: the air passing through the fins is warmer, while the air exiting directly from the hollow portion is cooler, affecting the comfort of the indoor environment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention proposes an air outlet and guide structure and a dehumidifier to improve the heat exchange efficiency of the heat sink, optimize the temperature uniformity of the exhaust air, and thus improve the comfort of the indoor environment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] In a first aspect, an air outlet and guide structure includes:

[0008] A fixed shell, wherein the interior of the fixed shell is hollow;

[0009] An isolation shell, the isolation shell is located inside the fixed shell, and the isolation shell is connected to the fixed shell to form at least one vertically arranged air outlet channel, and an air inlet of the air outlet channel is provided at one end of the fixed shell in the height direction;

[0010] An air guide portion is connected to one end of the isolation shell in the height direction, the air guide portion is close to the channel air inlet, and the air guide portion guides the outgoing air flow to the air outlet channel.

[0011] Preferably, the fixed shell and the isolation shell are both polyhedral structures, the air guide part is an arc-shaped curved surface, wherein the arc-shaped curved surface is one of a hemispherical shape, a semi-elliptical shape or an arc-shaped convex shape, and the convex part of the air guide part is close to the channel air inlet.

[0012] Preferably, the fixed shell and the isolation shell are both polyhedral structures, the air guide part is a polygonal pyramid, and the number of sides of the polygon on the bottom surface of the air guide part is the same as the number of sides of the polygon at one end of the isolation shell along the height direction, and the vertex of the air guide part is close to the channel air inlet.

[0013] Preferably, the air guide portion and the isolation shell are integrally formed.

[0014] Preferably, the end of the air guide portion is flush with an end of the fixed shell close to the air guide portion.

[0015] Preferably, the end of the air guide portion is located inside the fixed shell.

[0016] Preferably, the interior of the isolation shell is hollow, and the air guide portion seals one end of the isolation shell.

[0017] In a second aspect, a dehumidifier is provided, comprising the above-mentioned air outlet and guide structure.

[0018] Preferably, it further includes a shell arranged outside the air outlet and guide structure, an air inlet channel is formed between the air outlet and guide structure and the shell, and the outer side wall of the shell is provided with at least one air inlet.

[0019] Preferably, the shell is a cylindrical structure or a hollow polyhedron structure.

[0020] By adopting the above technical solution, the utility model has the following beneficial effects:

[0021] 1. The air outlet and guide structure of the present invention forms a vertical air outlet channel by connecting the isolation shell and the fixed shell, and the air guide part guides the outlet wind direction to the air outlet duct, ensuring that all air can pass through the hot end of the semiconductor refrigeration plate for heat exchange, giving full play to the role of the hot end of the semiconductor refrigeration plate, and greatly improving the heat exchange efficiency of the hot end of the semiconductor refrigeration plate; at the same time, in this solution, the air flows through the unified channel of the air outlet and guide structure, and undergoes the same processing flow, so that the exhaust air temperature is more uniform, avoiding the adverse effects of temperature differences on the comfort of the indoor environment, and significantly optimizing the temperature uniformity of the exhaust air.

[0022] 2. According to the principle of temperature difference in semiconductor refrigeration, the temperature difference in semiconductor refrigeration is constant. When the heat dissipation effect is improved, the temperature of the hot end of the refrigeration plate decreases, and the temperature of the cold end also decreases. In this utility model, the good air outlet and air guide structure promotes heat dissipation from the hot end of the semiconductor refrigeration plate, thereby reducing the temperature of the cold end of the semiconductor refrigeration plate, thereby improving the cooling efficiency, can reduce the air temperature more quickly, and achieve better cooling effect.

[0038] Example 1

[0039] See also Figure 1-Figure 2 , this embodiment 1 provides an air outlet and guide structure, including a fixed shell 1, an isolation shell 2 and an air guide portion 3, the interior of the fixed shell 1 is hollow; the isolation shell 2 is located inside the fixed shell 1, and the isolation shell 2 is connected to the fixed shell 1 and forms at least one vertically arranged air outlet channel 22, and the fixed shell 1 is provided with a channel air inlet 13 of the air outlet channel 22 at one end along the height direction; the air guide portion 3 is connected to one end of the isolation shell 2 along the height direction, the air guide portion 3 is close to the channel air inlet 13, and the air guide portion 3 guides the outgoing air flow to the air outlet channel 22.

[0040] Specifically, the fixed shell 1 is used to fix the semiconductor refrigeration plate, wherein the cold end 11 of the semiconductor refrigeration plate is fixed to the outer wall of the fixed shell 1, the hot end 12 of the semiconductor refrigeration plate is fixed to the inner wall of the fixed shell 1, and the hot end 12 of the semiconductor refrigeration plate is located in the air outlet channel 22. The channel air inlet 13 is arranged at the bottom of the fixed shell 1. Each air outlet channel 22 is composed of a side of the fixed shell 1 and the isolation shell 2 and two connecting plates 21. The air guide part 3 is arranged at the bottom of the isolation shell 2, and the air guide part 3 is connected to the isolation shell 2 to guide the air flow of the outlet to the air outlet channel 22, so that the dehumidified air in the dehumidifier can flow to the air outlet channel 22 and pass through the hot end 12 of the semiconductor refrigeration plate for heat exchange, thereby improving the efficiency of heat exchange at the hot end of the refrigeration plate and facilitating the discharge of air with uniform temperature.

[0041] See also Figure 1 as well as Figure 2 The fixed shell 1 and the isolation shell 2 are both polyhedral structures, and the air guide part 3 is an arc-shaped curved surface, wherein the arc-shaped curved surface is one of a hemispherical shape, a semi-elliptical shape or an arc-shaped convex shape, and the convex part of the air guide part 3 is close to the channel air inlet 13.

[0042] Specifically, in the present embodiment, the fixed shell 1 and the isolation shell 2 are both tetrahedral structures. The fixed shell 1 and the isolation shell 2 are connected by a connecting plate 21 to form four vertically arranged air outlet channels 22. The air guide portion 3 is hemispherical, and the circumference of the air guide portion 3 is connected to each side of the bottom of the isolation shell 2. During the air flow, the hemispherical air guide portion 3 can guide the air to the air outlet channels 22 more evenly. Because the hemispherical shape has a good curvature, after the air hits the surface of the air guide portion 3, it can be dispersed to the surroundings along the curvature of its surface and smoothly enter the air outlet channels 22. In some other embodiments, the fixed shell 1 and the isolation shell 2 can be trihedral structures or pentahedral structures, etc., and the air guide portion 3 can be semi-elliptical or other similar arc-shaped convex shapes. The shapes of the fixed shell 1, the isolation shell 2 and the air guide portion 3 can be designed as needed.

[0043] In other embodiments, both the fixed housing 1 and the isolation housing 2 are polyhedral structures, and the air guide 3 is in the shape of a polygonal pyramid. The number of sides of the polygonal bottom surface of the air guide 3 is the same as the number of sides of the polygonal bottom surface of the isolation housing 2 along the height direction. Each side of the bottom surface of the air guide 3 is connected to a corresponding side at one end of the isolation housing 2, and the vertex of the air guide 3 is close to the channel air inlet 13. The polygonal pyramid-shaped air guide 3 can guide air to the outlet channel 22 in a relatively concentrated manner. After the air flows into the air guide 3, it is guided along the side of the pyramid to the outlet channel 22.

[0044] See also Figure 1-Figure 2The air guide portion 3 is integrally formed with the isolation shell 2. The integrally formed design eliminates any connection gaps between the air guide portion 3 and the isolation shell 2, thereby reducing the possibility of air leakage and improving the integrity and stability of the structure.

[0045] See also Figure 1-Figure 2 The end of the air guide 3 is located inside the fixed housing 1. After the air enters the end area of ​​the air guide 3 inside the fixed housing 1, the space is relatively small and the air will be compressed to a certain extent, thereby increasing the air flow rate and pressure, so that the air can enter the air outlet channel 22 more effectively and exchange heat with other components more fully.

[0046] In some other embodiments, the end of the air guide portion 3 is flush with the end of the fixed housing 1 close to the air guide portion 3 .

[0047] See also Figure 1-Figure 2 The interior of the isolation shell 2 is hollow, and the air guide portion 3 seals one end of the isolation shell 2. While meeting the requirements of structural strength and air guide function, the amount of material used can be reduced.

[0048] Example 2

[0049] See also Figure 3-Figure 4 Embodiment 2 of the present invention provides a dehumidifier comprising the air outlet and guide structure described in Embodiment 1, a housing 4 mounted outside the air outlet and guide structure, a fan 5, and a water storage tank 6. An air inlet passage 42 is formed between the air outlet and guide structure and the housing 4, and at least one housing air inlet 41 is provided on the outer wall of the housing 4.

[0050] Specifically, in this embodiment, see Figure 3-Figure 4 , four air inlet channels 42 are formed between the air outlet and air guide structure and the outer shell 4. The cold end 11 of the semiconductor refrigeration plate is arranged on the outer wall of the outer shell 4 and is located in the air inlet channel 42. The outer wall of the outer shell 4 is provided with four outer shell air inlets 41. The four outer shell air inlets 41 are respectively connected to different air inlet channels 42. The fan 5 is arranged at the bottom of the outer shell 4. The water tank 6 is used to collect water droplets condensed during the dehumidification process. The water tank 6 is arranged in the outer shell 4 and is located below the fan 5. The top of the outer shell 4 is provided with an outer shell air outlet 43, which is connected to the air outlet channel 22. The outer shell 4 is a cylindrical structure or a hollow polyhedron structure, which can be selected according to actual needs and usage scenarios.

[0051] When the dehumidifier is started, fan 5 begins to operate, and its suction draws outside air from housing air inlet 41 into air inlet duct 42. Because the cold end 11 of the semiconductor refrigeration plate is located within air inlet duct 42, air quickly comes into contact with the cold end upon entering air inlet duct 42. Water vapor in the air is cooled and liquefied into water droplets, achieving initial dehumidification. The water droplets then fall under the influence of gravity into the water storage tank 6 below, where they are collected.

[0052] The air after preliminary dehumidification continues to flow under the push of the fan 5 and flows into the air guide part 3. The air guide part 3 guides the air to the air outlet channel 22 formed by the fixed shell 1 and the isolation shell 2 according to its shape (such as a hemispherical shape or a polygonal pyramid shape, etc.).

[0053] When air enters outlet duct 22, it passes through the hot end 12 of the semiconductor cooling element located therein, exchanging heat with the hot end 12. The air absorbs heat, raising its temperature. The heat-exchanged, temperature-homogenized air is then guided by the air guide structure and discharged from outlet duct 22 into the indoor environment through housing outlet 43. This regulates the indoor air humidity and, to a certain extent, controls the indoor temperature, improving indoor comfort.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
