Description

Technical Field

[0001] The invention relates to the technical field of heat exchange devices, and in particular to a condensation water seal structure and a rotary dehumidifier. Background Art

[0002] The principle of the rotary dehumidifier is to heat the air outside the machine into high-temperature and high-humidity air, and then transport the high-temperature and high-humidity air to the condenser to condense into water droplets, and the cycle is repeated to achieve the purpose of removing moisture from the air. Among them, the condenser has a condenser tube, a wind cavity connected to the condenser tube, and a drain pipe connected to the wind cavity. When the high-temperature and high-humidity gas passes through the condenser tube, water droplets condense and accumulate in the wind cavity, and the water droplets are then discharged to the outside through the drain pipe, that is, the drain pipe connects the external environment and the wind cavity, which is not good for the entire air circulation system, because when the gas enters the wind cavity, part of the external air will be sucked into the wind cavity from the drain pipe, and when the gas is discharged from the wind cavity, part of the hot air will be discharged to the outside from the drain pipe, resulting in a decrease in the efficiency of the fan driving the airflow in and out of the wind cavity, resulting in a decrease in the overall dehumidification capacity of the dehumidifier.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figures 1 to 3A condensation water seal structure of the present invention includes: a shell 100; a drain pipe 200, which is arranged in the shell 100 and communicated with the inner cavity of the shell 100; a water storage container 300, which is arranged outside the drain pipe 200, and the water storage container 300 has a water storage tank 310, and the output end of the drain pipe 200 extends into the water storage tank 310, and the water storage container 300 is provided with a connecting port 320 which is connected to the water storage tank 310 and is located above the output end of the drain pipe 200.

[0031] When the condensed water droplets in the shell 100 are discharged outward from the drain pipe 200, the water enters the water tank 310 of the water storage container 300. When the water in the water tank 310 rises to the output end of the sealed drain pipe 200, the connecting port 320 is isolated from the output end of the drain pipe 200, and the gas cannot enter or leave the shell 100 from the drain pipe 200, thereby ensuring the airtightness inside the shell 100, which is beneficial to improving the gas circulation efficiency and thus improving the heat exchange efficiency.

[0032] See also Figure 3 and Figure 4 In some embodiments of the present invention, the water storage container 300 is a sleeve, which includes a bottom plate 301 and a surrounding plate 302 arranged on the bottom plate 301, and the surrounding plate 302 is sleeved on the outer periphery of the end of the drain pipe 200, and the surrounding plate 302 and the bottom plate 301 define the water storage tank 310 whose opening edge is located above the output end of the drain pipe 200, and there is a gap between the surrounding plate 302 and the outer peripheral wall of the drain pipe 200 to form the connecting port 320. It is understandable that the sleeve of the above structure is directly connected to the drain pipe 200, eliminating other installation structures. The condensed water flows into the water storage tank 310 from the end of the drain pipe 200. When the water level in the water storage tank 310 rises to the port that seals the drain pipe 200, the external gas cannot enter the shell 100 from the drain pipe 200, and the hot air flow in the shell 100 cannot leave the shell 100 through the drain pipe 200. When the water in the water storage tank 310 continues to rise to the upper end of the enclosure 302 to overflow from the above gap, the drainage action is achieved. Of course, in other embodiments, the water storage container 300 can be installed on the outside of the shell 100 and receive the drain pipe 200 by bolts, elastic bands or other fasteners.

[0033] See also Figure 3 and Figure 4In some embodiments of the present invention, a groove 330 is formed on the upper surface of the bottom plate 301, and the groove 330 extends to the inner peripheral wall of the enclosure 302 to communicate with the communication port 320. The port of the drain pipe 200 abuts against the upper surface of the bottom plate 301 and communicates with the groove 330. Through the above structural setting, a small amount of condensed water discharged from the drain pipe 200 can fill the groove 330, thereby sealing the port of the drain pipe 200. The machine can seal the gas inlet and outlet channel in a short working time, which is further conducive to improving the gas circulation efficiency, heat exchange efficiency and dehumidification efficiency, etc.

[0034] See also Figure 2 and Figure 3 In some embodiments of the present invention, the bottom plate 301 is elliptical, and two drain pipes 200 are provided. The two drain pipes 200 are arranged at intervals along the length direction of the bottom plate 301, and the enclosure 302 is arranged around the contour edge of the bottom plate 301 to surround the outside of the two drain pipes 200. The groove 330 includes at least one first long groove 331 extending along the length direction of the bottom plate 301 and at least two second long grooves 332 extending along the width direction of the bottom plate 301. It can be understood that the condenser of the rotary dehumidifier is generally provided with a drain pipe 200 on the air inlet chamber 122 and the exhaust chamber 123 so as to effectively discharge the condensed water in the shell 100. The sleeve of the above structure can simultaneously receive the water discharged by the two drain pipes 200, and the water capacity of the groove 330 is not significantly increased. Similarly, a small amount of condensed water can fill the groove 330 and seal the port of the drain pipe 200, which is beneficial to improving the gas circulation efficiency, heat exchange efficiency and dehumidification efficiency.

[0035] See also Figure 6 In some embodiments of the present invention, the bottom plate 301 is circular, the enclosure 302 is arranged around the edge of the bottom plate 301, and the groove 330 is a cross groove, and the center of the cross groove coincides with the center of the bottom plate 301. Specifically, the drain pipe 200 is a circular tube arranged concentrically with the bottom plate 301, and the outer diameter of the circular tube is smaller than the inner diameter of the enclosure 302 to form a connecting port 320. The water discharged from the drain pipe 200 can quickly spread from the center of the cross groove to the surroundings of the sleeve to overflow, which is conducive to the rapid discharge of condensed water and avoids water accumulation at a certain position.

[0036] See also Figure 4 or Figure 6In some embodiments of the present invention, at least two pressing parts 340 are protruding from the inner peripheral wall of the enclosure 302 and are tightly matched with the outer peripheral wall of the drain pipe 200. At least part of the communication port 320 is defined between two adjacent pressing parts 340, the inner peripheral wall of the enclosure 302 and the outer peripheral wall of the drain pipe 200. The pressing parts 340 are tightly matched with the outer peripheral wall of the drain pipe 200, so that the sleeve is convenient to assemble when it is sleeved on the outside of the drain pipe 200, and the communication port 320 can be directly formed when the sleeve is connected to the drain pipe 200.

[0037] See also Figure 4 In some embodiments of the present invention, the tightening component 340 is a rib plate formed on the inner peripheral wall of the enclosure 302 and arranged perpendicular to the bottom plate 301. The corner of the rib plate away from the enclosure 302 is provided with a guide slope 341 for guiding the drain pipe 200 to be inserted into the water storage tank 310. In this embodiment, the sleeve composed of the rib plate, the bottom plate 301 and the enclosure 302 is obtained by integral injection molding, which is very convenient for production and processing. Moreover, when the rib plate made of plastic material is pressed against the outer peripheral wall of the drain pipe 200, it can produce elastic deformation and fit tightly with the drain pipe 200 without adhesive fixation. The setting of the guide slope 341 is conducive to the insertion of the port of the drain pipe 200 along the height direction of the rib plate. Of course, in other embodiments, the sleeve composed of the rib plate, the bottom plate 301 and the enclosure 302 can also be obtained by integral casting.

[0038] See also Figure 1 and Figure 2 In some embodiments of the present invention, the shell 100 includes an upper box body 110, a lower box body 120 and a plurality of condensing tubes 130. The interior of the lower box body 120 is provided with a partition 121 for dividing its inner cavity into an air inlet cavity 122 and an exhaust cavity 123. The lower box body 120 is provided with an air inlet port 124 connected to the air inlet cavity 122 and an exhaust port 125 connected to the exhaust cavity 123. The two ends of the plurality of condensing tubes 130 are respectively connected to the air inlet cavity 122 and the inner cavity of the upper box body 110, and the two ends of the remaining condensing tubes 130 are respectively connected to the exhaust cavity 123 and the inner cavity of the upper box body 110. The bottom of the air inlet cavity 122 and / or the exhaust cavity 123 is connected with the drain pipe 200.

[0039] It can be understood that the high-temperature and high-humidity gas enters the air inlet cavity 122 from the air inlet 124, passes through multiple condensers 130 and then enters the upper box body 110. During this process, some water droplets will be generated in the condenser tubes 130, and the water droplets will flow down along the condenser tubes 130 to the inner wall of the air inlet cavity 122. The gas located in the upper box body 110 continues to pass through the remaining condensers 130 and then enters the exhaust cavity 123, and then is discharged from the exhaust port 125 and then returns to the air inlet 124 after heating to realize the gas circulation of the dehumidification function. According to the needs of use, a drain pipe 200 can be set at the bottom of the air inlet cavity 122 and / or the exhaust cavity 123 to drain water. Correspondingly, each drain pipe 200 is also equipped with the above-mentioned water storage cavity. When the water in the water storage tank 310 rises to the sealed drain pipe 200, the gas cannot enter or leave the shell 100 from the drain pipe 200, thereby ensuring the airtightness inside the shell 100, which is conducive to improving the gas circulation efficiency and thus improving the heat exchange efficiency.

[0040] See also Figure 5 In some embodiments of the present invention, the housing 100 includes an air duct 140, in which a heating component 400 and a fan 500 are arranged, one end of the air duct 140 is connected to a dehumidification wheel 600, and the other ends of the dehumidification wheel 600 and the air duct 140 are respectively connected to the input end and the output end of the condenser, and the drain pipe 200 is arranged at the bottom side of the air duct 140. It can be understood that the heating component 400 heats the gas near the dehumidification wheel 600, and the fan 500 drives the heated gas to circulate between the air duct 140 and the condenser, and the gas with moisture will partially condense on the inner wall of the air duct 140. At this time, the water droplets attached to the inner wall of the air duct 140 can be discharged through the drain pipe 200, and the drain pipe 200 is also configured with the above-mentioned water storage cavity, which is conducive to improving the dehumidification efficiency.

[0041] The present invention also discloses a rotary dehumidifier, including a condensation water seal structure of any of the above-mentioned technical solutions; when condensed water droplets accumulate in the water storage tank 310 and the water level rises to the output end of the sealed drain pipe 200, the connecting port 320 is isolated from the output end of the drain pipe 200, ensuring the airtightness inside the shell 100, which is beneficial to improving the gas circulation efficiency and thus improving the dehumidification efficiency.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
