Description

Technical Field

[0001] This utility model relates to the field of condensation device technology, and in particular to a condensation device and a rotary dehumidifier. Background Technology

[0002] Rotary dehumidifiers typically heat outside air to a high temperature and humidity level, then deliver this hot, humid air to a condenser unit for condensation, thus removing moisture from the air. This condenser unit usually consists of multiple condenser tubes. When the hot, humid air passes through these tubes, it comes into contact with the tube walls and condenses into water droplets. To improve the condensation efficiency, as many condenser tubes as possible are usually arranged within a limited volume. The more condenser tubes there are, the smaller their diameter needs to be. However, because the condensation tubes are small, when the water droplets accumulate and form large droplets, they can easily fill the condenser tubes and form a water film. This water film blocks the condenser tubes, obstructing airflow and preventing further effective condensation. This severely impacts the dehumidification efficiency of the rotary dehumidifier, and may even cause it to malfunction. Utility Model Content

This makes the cuts at both ends of the condensation channel larger in area than traditional horizontal cuts, thereby increasing the difficulty for condensate to form a water film when passing through both ends of the condensation channel, reducing the risk of condensate accumulating and forming a water film that blocks the condensation channel, and improving the condensation effect of the condensation device.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 4 This utility model provides a condensation device, which includes a housing 100 and a condensation assembly. The housing 100 has an air inlet chamber 110 and an air outlet chamber 120, and also has an air inlet 111 and an air outlet 121. The air inlet 111 communicates with the air inlet chamber 110, and the air outlet 121 communicates with the air outlet chamber 120. The condensation assembly is installed in the housing 100 and has a condensation channel. One end of the condensation channel extends into and communicates with the air inlet chamber 110, and the other end extends into and communicates with the air outlet chamber 120. Both ends of the condensation channel are provided with a waterproof membrane structure, which includes at least one cross-section 230 located around the periphery of the condensation channel. The cross-section 230 has a tangential angle α, where α > 0°, with the radial direction of the condensation channel.

[0034] In the condensation device of this embodiment, high-heat and high-humidity gas can enter the inlet chamber 110 through the inlet 111, and then be condensed into dry gas through the condensation channel before entering the outlet chamber 120 and finally flowing out from the outlet 121. By setting waterproof membrane structures at both ends of the condensation channel, that is, setting waterproof membrane structures at both ends of the condensation channel extending into the inlet chamber 110 and the outlet chamber 120, since the waterproof membrane structure includes at least one cross-section 230 on the periphery of the condensation channel, and the cross-section 230 has a tangent angle α with the radial direction of the condensation channel, α > 0°, the periphery of both ends of the condensation channel forms a non-horizontal cross-section, thereby making the cut at both ends of the condensation channel larger in area than the traditional horizontal cut. This increases the difficulty for condensate to form a water film when passing through both ends of the condensation channel, reduces the risk of condensate accumulating and forming a water film that blocks the condensation channel, and is beneficial to improving the condensation effect of the condensation device.

[0035] Reference Figures 1 to 2 In some embodiments, the condensation channel includes at least one air inlet channel 210, a connecting channel 310, and at least one air outlet channel 220. The air inlet channel 210 connects the connecting channel 310 and the air inlet chamber 110, and the air outlet channel 220 connects the connecting channel 310 and the air outlet chamber 120. Each end of the air inlet channel 210 and each end of the air outlet channel 220 are provided with a waterproof membrane structure.

[0036] By adopting the above structure, during use, the hot and humid gas enters the intake chamber 110 through the intake port 111, flows through each intake channel 210 to the connecting channel 310, then flows along the connecting channel 310 to the outlet channel 220, and finally flows along the outlet channel 220 to the outlet chamber 120 and exits from the outlet port 121. By setting the condensation channels as intake channels 210, connecting channels 310 and outlet channels 220 connected in series, the gas flow path can be extended, the gas condensation time can be extended, and thus the condensation effect can be improved. In addition, by setting waterproof membrane structures at both ends of each intake channel 210 and each outlet channel 220, the difficulty of forming a water film when the gas passes through the ends of the intake channel 210 and the ends of the outlet channel 220 can be increased, further reducing the risk of condensate accumulating and forming a water film that blocks the condensation channels, which is conducive to further improving the condensation effect of the condensation device.

[0037] Reference Figures 1 to 2 In some embodiments, the number of intake channels 210 is greater than the number of exhaust channels 220.

[0038] Since the hot and humid gas flows sequentially from the air inlet chamber through the air inlet channel 210, the connecting channel 310, and the air outlet channel 220 before finally flowing into the air outlet chamber, the moisture content of the gas in the air inlet chamber is higher than that of the gas in the air outlet chamber 120. By adopting the above structure, the number of air inlet channels 210 is set to be greater than the number of air outlet channels 220, which facilitates rapid condensation and dehumidification of the gas flowing out of the air inlet chamber 110, and is conducive to further optimizing the condensation effect of the condensation device.

[0039] Reference Figures 1 to 4 In some embodiments, the condensation assembly includes a connecting member 300 and at least two condenser tubes 200. The connecting member 300 is located above the housing 100, and a connecting channel 310 is formed in the connecting member 300. The condenser tubes 200 are installed between the housing 100 and the connecting member 300 and extend upward into the connecting channel 310. At least one condenser tube 200 extends downward into the air inlet chamber 110 and has an air inlet channel 210. At least one condenser tube 200 extends downward into the air outlet chamber 120 and has an air outlet channel 220. Each condenser tube 200 has a waterproof membrane structure at both ends.

[0040] By adopting the above structure, the condensation assembly includes a connecting member 300 and at least two condenser tubes 200. The connecting member 300 is disposed above the housing 100, and the condenser tubes 200 are disposed between the connecting member 300 and the housing 100. Thus, in use, after the hot and humid gas enters the intake chamber 110 through the intake port 111, it can flow upward through each intake channel 210 to the connecting channel 310, and then flow along the connecting channel 310 to the outlet channel 220. Finally, it flows downward along the outlet channel 220 to the outlet chamber 120 and flows out from the outlet port 121. During this process, the gas in the intake chamber 110 needs to flow from bottom to top along the intake channel 210 to the connecting channel 310, which can prolong the flow time of the gas in the intake channel 210, so that the gas can fully contact the inner wall of the intake channel 210. This facilitates effective condensation and dehumidification of the gas flowing out of the intake chamber 110, which is beneficial to further optimize the condensation effect of the condensation device.

[0041] Understandably, referring to Figures 1 to 2 To further improve the condensation effect of the condensing device, the condensing tubes 200 can be arranged at intervals, which facilitates heat dissipation from each condensing tube 200 and improves the condensation effect of the condensing tubes 200.

[0042] Reference Figures 1 to 4 In some embodiments, the waterproof membrane structure includes a cut surface 230 that is obliquely cut to the condenser tube 200, and in the vertical direction, the projection of the condenser tube 200 is located within the projection of the corresponding cut surface 230.

[0043] By adopting the above structure, the waterproof membrane structure is set as a cut surface 230 obliquely cut into the condenser tube 200, which is simple in structure and easy to process. In addition, the cut surface 230 at both ends of the condenser tube 200 has a larger area than the horizontal cut surface, which is conducive to the inflow and outflow of gas and facilitates the delivery of gas into the condenser tube 200 for condensation. Furthermore, the setting of the cut surface 230 can also form a sharp point on the end face of the condenser tube 200, which can facilitate the installation of the condenser tube 200, making it easy to insert both ends of the condenser tube 200 into the housing 100 and the connecting member 300, thereby improving the installation efficiency of the condenser tube 200.

[0044] It is understood that in some embodiments, the cut surface 230 is obliquely cut to the condenser tube 200, that is, the cut surface 230 is a plane located at the end of the condenser tube 200 and inclined relative to the horizontal plane, which facilitates the processing of the cut surface 230. Of course, in addition, the cut surface 230 can also be set as a curved surface. This utility model does not specifically limit this, as long as the tangent angle α between the cut surface 230 and the radial direction of the condenser tube 200 is greater than 0°, that is, the cut surface 230 is not a horizontal plane. This allows for the formation of non-horizontal cuts at both ends of the condenser tube 200 with a larger area than the horizontal cut, which helps to increase the difficulty of forming a water film when the gas passes through both ends of the condenser tube 200, further reducing the risk of condensate accumulating and forming a water film that blocks the condensation channel, and further improving the condensation effect of the condensation device.

[0045] In some embodiments, the cut surface 230 includes a first cut surface and a second cut surface, the first cut surface and the second cut surface are arranged in a V-shape, and there is a V-shaped cut between the first cut surface and the second cut surface.

[0046] By adopting the above structure, the cut surface 230 is set as a V-shaped cut surface 230, and a V-shaped cut is formed. This can increase the cut area compared to a horizontal cut, increase the difficulty of water film formation, further reduce the risk of condensate accumulating and forming a water film that blocks the condensation channel, and help to further improve the condensation effect of the condensation device.

[0047] It is understood that, in addition to setting the cut surface 230 as a V shape, it can also be set as a W shape or other shapes, and this utility model does not specifically limit it in this regard.

[0048] Reference Figures 1 to 2 In some embodiments, the housing 100 includes a bottom shell 130 and a cover 140. A partition 150 is provided inside the bottom shell 130. An air inlet chamber 110 and an air outlet chamber 120 are located in the bottom shell 130 and separated by the partition 150. An air inlet 111 is opened in the bottom shell 130 and communicates with the air inlet chamber 110, and an air outlet 121 is opened in the bottom shell 130 and communicates with the air outlet chamber 121. The cover 140 covers the bottom shell 130 and interlocks with it. All condenser tubes 200 are inserted into the cover 140 and extend downwards into the bottom shell 130.

[0049] By adopting the above structure, the housing 100 is divided into a bottom shell 130 and a cover 140 that can be interlocked, which facilitates the processing and installation of the housing 100. By providing a partition 150 inside the housing 100, the bottom shell 130 can be divided into an air inlet chamber 110 and an air outlet chamber 120, which facilitates the processing and opening of the air inlet chamber 110 and the air outlet chamber 120.

[0050] It is understandable that by dividing the housing 100 into a bottom shell 130 and a cover 140, it is also convenient to directly machine the first mounting hole for installing the condenser tube 200 on the cover 140, thereby facilitating the installation of the condenser tube 200.

[0051] Understandably, referring to Figure 1 and Figure 2 In some embodiments, the bottom shell 130 is provided with a first buckle 131, and the cover 140 is provided with a first locking block 141. During installation, the cover 140 can be placed on top of the bottom shell 130, and the first locking block 141 can be engaged with the buckle of the first buckle 131, thereby achieving a snap-fit ​​installation between the cover 140 and the bottom shell 130. The number of first buckles 131 and first locking blocks 141 can be set to one, two, or more sets, with each first locking block 141 and each first buckle 131 arranged in a one-to-one correspondence, thereby improving the installation stability between the cover 140 and the bottom shell 130. In addition, besides setting the first buckle 131 on the bottom shell 130 and the first locking block 141 on the cover 140, the first buckle 131 can also be set on the cover 140 and the first locking block 141 on the bottom shell 130. This utility model does not specifically limit the specific embodiment in this way.

[0052] Reference Figure 1 and Figure 2 In some embodiments, the bottom wall of the air inlet chamber 110 is provided with a first water outlet 112, and the bottom wall of the air inlet chamber 110 is also provided with a first guide surface 113 that slopes downward toward the first water outlet 112.

[0053] By adopting the above structure, when the hot and humid gas flows from the air inlet chamber 110 through the air inlet channel 210, it can come into contact with the inner wall of the air inlet channel 210 and condense to form condensate. The condensate can flow downward along the air inlet channel 210 back into the air inlet chamber 110. The first outlet 112 can facilitate the discharge of condensate in the air inlet chamber 110, and the first guide surface 113 can guide the condensate to flow downward to the first outlet 112. Thus, the condensate in the air inlet chamber can be discharged in time, avoiding the accumulation of condensate in the air inlet chamber and affecting the condensation and dehumidification effect of the condensation device.

[0054] Reference Figure 1 and Figure 2 In some embodiments, the bottom wall of the air outlet chamber 120 is provided with a second water outlet 122, and the bottom wall of the air outlet chamber 120 is provided with a second guide surface 123 that slopes downward toward the second water outlet 122.

[0055] By adopting the above structure, when the gas flows through the connecting channel 310 and passes through the outlet channel 220, it can come into contact with the inner wall of the outlet channel 220 and condense to form condensate. The condensate can flow downward along the outlet channel 220 into the outlet chamber 120. The setting of the second water outlet 122 can facilitate the discharge of the condensate in the outlet chamber 120. The setting of the second guide surface 123 can guide the condensate to flow downward to the second water outlet 122. Thus, the condensate in the outlet chamber can be discharged in time, avoiding the accumulation of condensate in the outlet chamber and affecting the condensation and dehumidification effect of the condensation device.

[0056] Reference Figure 1 and Figure 2 In some embodiments, the connecting member 300 includes a connecting seat 320 and a connecting cover 330 that are interlocked with each other. The connecting channel 310 is formed by the connecting cover 330 and the connecting seat 320 surrounding each other. All condenser tubes 200 are inserted into the connecting cover 330 and extend upward into the connecting channel 310.

[0057] By adopting the above structure, the connecting member 300 is separately disposed in the interlocking connecting seat 320 and connecting cover 330, thereby facilitating the processing and assembly of the connecting member 300. In addition, this structure also allows for the direct opening of a second mounting hole for installing the condenser tube 200 on the connecting cover 330, making the installation of the condenser tube 200 more convenient.

[0058] Understandably, referring to Figure 1 and Figure 2 In some embodiments, the connecting seat 320 is provided with a second latch 321, and the connecting cover 330 is provided with a second latching block 331. During installation, the connecting cover 330 can be placed on the connecting seat 320, and the second latching block 331 can be engaged with the latch of the second latch 321. This achieves a snap-fit ​​installation between the connecting seat 320 and the connecting cover 330. The number of second latches 321 and second latching blocks 331 can be set to one, two, or more sets, with each second latching block 331 corresponding to each second latch 321, thereby improving the installation stability between the connecting seat 320 and the connecting cover 330. In addition, besides setting the second latch 321 on the connecting seat 320 and the second latching block 331 on the connecting cover 330, the second latch 321 can also be set on the connecting cover 330 and the second latching block 331 on the connecting seat 320. This utility model does not specifically limit this.

[0059] An embodiment of this utility model also proposes a rotary dehumidifier, which is equipped with the condensation device of any of the above embodiments.

[0060] In the rotary dehumidifier of this utility model embodiment, by setting the condensation device of any of the above embodiments, at least one cross-section 230 is provided at both ends of the condensation channel of the condensation device, and the cross-section 230 has a tangent angle α with the radial direction of the condensation channel, where α > 0°, so that the two ends of the condensation channel form a non-horizontal cross-section. This increases the difficulty of condensate forming a water film when passing through the two ends of the condensation channel, reduces the risk of condensate accumulating and forming a water film that blocks the condensation channel, and helps to improve the condensation effect of the condensation device, reduce the impact of the water film on the dehumidification effect of the rotary dehumidifier, and improve the dehumidification effect of the rotary dehumidifier.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
