Description

Technical Field

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

[0002] In modern home life, people's demands for indoor environmental comfort are increasing, and air humidity, as one of the key factors affecting comfort, has received much attention. Inappropriate humidity levels can cause a series of problems. For example, in humid seasons, excessively high indoor humidity can cause water droplets to form on the surfaces of clothing, furniture, and other items, leading to mold growth on clothing and deformation or damage to furniture. It also provides a breeding ground for harmful microorganisms such as bacteria and mold, endangering the health of family members. Furthermore, high humidity can make people feel stuffy and sticky, seriously affecting the comfort of living in the home.

[0003] Rotary dehumidifiers, as an effective humidity control device, have emerged to reduce indoor air humidity and improve the comfort of the living environment through a series of complex working mechanisms. Traditional rotary dehumidifiers mainly consist of a condenser, a moisture-absorbing rotor, and a hot air circulation system. The condenser includes a base, condenser pipes, and connecting seats arranged from bottom to top, while the hot air circulation system includes a circulating fan and a heating element. Its working process is as follows: When the rotary dehumidifier starts, the circulating fan near the air outlet of the base begins to operate, blowing air into the heating element. The heating element inside the heating element is energized and heats up, raising the air temperature to form hot air. The hot air then enters the moisture-absorbing rotor. If the rotor is saturated with moisture, the adsorbed moisture will be released and mixed into the hot air, forming a heated airflow carrying moisture. Next, the heated airflow enters the air inlet of the base, where it is diverted into the condenser pipes. The condenser tube is made of a material with good thermal conductivity. When the heated airflow flows through the condenser tube, heat is transferred to the outside air through the tube wall, cooling the heated airflow and causing the moisture in it to condense. Afterward, the heated airflow is transmitted through the condenser tube to the connector, then flows back to the condenser tube, and finally returns to the base and is discharged from the air outlet.

[0004] However, existing rotary dehumidifiers suffer from insufficient moisture condensation due to the short residence time of the heated airflow within the condenser tubes. This results in inadequate regeneration of the moisture-absorbing rotor, gradually reducing its ability to adsorb moisture and ultimately hindering its overall dehumidification performance, making it difficult to meet people's needs for a comfortable living environment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a condensation device that solves problems such as short residence time of heated airflow in the condenser tube, insufficient regeneration of the moisture-absorbing rotor, and poor dehumidification effect in existing rotary dehumidifiers. This improves the overall dehumidification performance of the rotary dehumidifier and creates a more comfortable living environment for users.

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

[0007] In a first aspect, a condensation device is provided, comprising:

[0008] The base includes a first cavity, and a partition plate is provided in the first cavity to divide the first cavity into an air inlet cavity and an air outlet cavity. The volume of the air inlet cavity is larger than the volume of the air outlet cavity.

[0009] Connecting seat, the connecting seat including a second cavity;

[0010] The condensation assembly includes a plurality of first condenser tubes and a plurality of second condenser tubes. The two ends of the first condenser tubes are respectively connected to the air inlet cavity and the second cavity, and the two ends of the second condenser tubes are respectively connected to the air outlet cavity and the second cavity. The number of first condenser tubes is greater than the number of second condenser tubes.

[0011] Preferably, the volume ratio of the air inlet cavity to the air outlet cavity is (3-4):1.

[0012] Preferably, the volume ratio of the air inlet cavity to the air outlet cavity is 3:1.

[0013] Preferably, the partition plate is folded and corrugated.

[0014] Preferably, the ratio of the number of the first condenser tubes to the number of the second condenser tubes is (3-4):1.

[0015] Preferably, the ratio of the number of the first condenser tubes to the number of the second condenser tubes is 3:1.

[0016] Preferably, the condensation assembly further includes a first mounting portion and a second mounting portion, wherein the first condenser pipe and the second condenser pipe are detachably mounted between the first mounting portion and the second mounting portion.

[0017] Preferably, the first mounting part is detachably connected to the base, and the second mounting part is detachably connected to the connecting seat.

[0018] Secondly, this utility model also provides a rotary dehumidifier, including the aforementioned condensation device.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects:

[0020] When the hot circulating air from the rotary dehumidifier enters the condenser, it first flows into the inlet chamber. Because the partition plate divides the first cavity into an inlet chamber and an outlet chamber, and the volume of the inlet chamber is larger than that of the outlet chamber, according to the relationship between volume and residence time in fluid mechanics (residence time = volume ÷ flow rate; at a constant flow rate, the larger the volume, the longer the residence time), the hot circulating air has a relatively long residence time in the inlet chamber, and the airflow velocity is relatively slowed. This provides more favorable initial conditions for subsequent condensation. Subsequently, the hot circulating air enters the first condenser tubes. Since there are more first condenser tubes than second condenser tubes, the first condenser tubes provide a larger total surface area and a more complex flow path for the hot circulating air. According to the principle of heat exchange, a larger surface area and a longer path facilitate heat transfer, allowing the heat in the hot circulating air to dissipate more fully, thus causing the moisture to condense completely. Meanwhile, under the same flow rate, the amount of airflow distributed in each first condenser tube is relatively small. According to the continuity equation of fluid mechanics (Q=A×V, where Q is the flow rate, A is the cross-sectional area, and V is the velocity; when Q is constant, an increase in A results in a decrease in V), this leads to a slower flow velocity of the hot circulating air in the first condenser tube, thereby prolonging the contact time between the airflow and the tube wall, promoting heat exchange and moisture condensation. The humidity of the hot circulating air after treatment by the condensation device is significantly reduced, completing the regeneration process of the rotary device and ensuring that the rotary device continuously and stably dehumidifies the intake humid air, thus significantly improving the dehumidification capacity of the rotary dehumidifier. Under the same operating conditions, compared with the condensation device in a traditional rotary dehumidifier, the condensation device of this invention can significantly improve the dehumidification capacity of the rotary dehumidifier.

[0038] Example 1

[0039] See Figure 1 and Figure 2 Embodiment 1 of this utility model discloses a condensation device comprising: a base 1, a connecting seat 2, and a condensation component 3. The condensation component 3 is installed between the base 1 and the connecting seat 2, with the base 1 communicating with the condensation component 3 and the connecting seat 2 communicating with the condensation component 3.

[0040] See Figure 2 The base 1 includes a first cavity 11, within which a partition plate 12 is provided. The partition plate 12 is folded and corrugated, dividing the first cavity 11 into an air inlet cavity 111 and an air outlet cavity 112. The volume of the air inlet cavity 111 is larger than that of the air outlet cavity 112. The base 1 is provided with a condenser air inlet 13 and a condenser air outlet 14. The condenser air inlet 13 communicates with the air inlet cavity 111, and the condenser air outlet 14 communicates with the air outlet cavity 112. The volume ratio of the air inlet cavity 111 to the air outlet cavity 112 is (3-4):1. Preferably, the volume ratio of the air inlet cavity 111 to the air outlet cavity 112 is 3:1. When hot circulating air enters the base 1 from the condenser air inlet 13, due to the larger volume of the air inlet cavity 111, the speed of the hot circulating air will decrease after entering, achieving initial buffering. When the hot circulating air flows through the folded corrugated partition plate 12, it creates a complex flow path. The corrugated structure increases the residence time of the hot circulating air in the base 1.

[0041] See Figure 2The connecting seat 2 includes a second cavity. The condensing assembly 3 includes a plurality of first condensing tubes 31 and a plurality of second condensing tubes 32. The two ends of the first condensing tubes 31 are connected to the air inlet cavity 111 and the second cavity, respectively. The two ends of the second condensing tubes 32 are connected to the air outlet cavity 112 and the second cavity, respectively. The number of first condensing tubes 31 is greater than the number of second condensing tubes 32. The ratio of the number of first condensing tubes 31 to the number of second condensing tubes 32 is (3-4):1. Preferably, the ratio of the number of first condensing tubes 31 to the number of second condensing tubes 32 is 3:1. Under the same hot air circulation flow rate, since the number of second condensing tubes 32 is less than that of first condensing tubes 31, the hot air flows through the first condensing tubes 31, and its flow rate slows down because there are more paths that can be passed. The reduced flow rate means that the hot air circulation stays in the first condensing tubes 31 for a longer time, thus allowing more time for heat exchange, promoting moisture condensation, improving condensation efficiency, and laying the foundation for the high-efficiency dehumidification of the entire rotary dehumidifier.

[0042] See Figure 1 and Figure 2 The condenser assembly 3 also includes a first mounting portion 33 and a second mounting portion 34, with the first condenser pipe 31 and the second condenser pipe 32 detachably mounted between the first mounting portion 33 and the second mounting portion 34. Specifically, the first mounting portion 33 has a plurality of first fixing holes 331 for mounting the first condenser pipe 31 and the second condenser pipe 32, and the second mounting portion 34 has a plurality of second fixing holes 341 for mounting the first condenser pipe 31 and the second condenser pipe 32. The first fixing holes 331 and the second fixing holes 341 respectively fix the two ends of the first condenser pipe 31 and the second condenser pipe 32.

[0043] Further, see Figure 2 The first mounting part 33 is detachably connected to the base 1, and the second mounting part 34 is detachably connected to the connecting seat 2. Specifically, the outer wall of the first mounting part 33 is provided with multiple first protrusions 332, and the outer wall of the base 1 is provided with multiple first fastening parts 17. The base 1 and the first mounting part 33 are detachably connected by the engagement of the first protrusions 332 and the first fastening parts 17. The outer wall of the second mounting part 34 is provided with multiple second protrusions 342, and the outer wall of the connecting seat 2 is provided with multiple second fastening parts 21. The connecting seat 2 and the second mounting part 34 are detachably connected by the engagement of the second protrusions 342 and the second fastening parts 21. When a comprehensive overhaul or maintenance of the entire condensing unit is required, the operator can quickly remove the first mounting part 33 from the base 1 and the second mounting part 34 from the connecting seat 2, thereby facilitating the inspection, cleaning, or maintenance of the condenser tube assembly, the interior of the base 1, and the interior of the connecting seat 2.

[0044] The implementation principle of Example 1 is as follows:

[0045] Throughout the condensation process, the hot circulating air enters from the condensation air inlet 13 of the base 1. Since the volume of the air inlet cavity 111 is larger than that of the air outlet cavity 112, the speed of the hot circulating air decreases here, achieving initial buffering. At the same time, the folded corrugated partition plate 12 creates a complex path, increasing the residence time of the hot circulating air.

[0046] Then, the hot circulating air enters the first condenser tube 31. Because there are many first condenser tubes 31, at the same flow rate, the hot circulating air's velocity decreases, its path becomes more complex, and its total surface area is larger. According to the principles of heat exchange and fluid mechanics, this prolongs the residence time of the hot circulating air within the first condenser tubes 31, allowing heat to dissipate more fully and moisture to condense in large quantities. Afterward, the hot circulating air enters the second condenser tube 32 for further optimized condensation.

[0047] Throughout the process, all components work together to effectively solve the problem of short residence time of heated airflow in the condenser tube in traditional rotary dehumidifiers, thereby improving condensation efficiency and dehumidifying performance, creating a more comfortable living environment for users.

[0048] Example 2

[0049] See Figure 3 and Figure 4 Embodiment 2 of this utility model discloses a rotary dehumidifier, including a housing 4, which includes a receiving cavity. The housing 4 is rectangular, and its opposite side walls are provided with an air inlet 41 and an air outlet. An air supply device 5, a condenser device, a rotary device 6, and a hot air circulation device 7 are sequentially connected and installed in the receiving cavity from the air inlet 41 to the air outlet. The air inlet of the hot air circulation device 7 is connected to the condenser air outlet 14, and the air outlet of the hot air circulation device 7 is connected to the condenser air inlet 13. The air inlet 41 is close to the air supply device 5, and the air outlet is close to the hot air circulation device 7.

[0050] The rotary dehumidifier also includes a water storage tank 8, which is installed at the bottom of the receiving cavity and located at the bottom of the condensation device. The bottom of the base 1 is connected to a first flow pipe 15 and a second flow pipe 16. The two ends of the first flow pipe 15 are connected to the air inlet cavity 111 and the water storage tank 8, respectively, and the two ends of the second flow pipe 16 are connected to the air outlet cavity 112 and the water storage tank 8, respectively.

[0051] When the rotary dehumidifier starts working, the air supply device 5 draws humid air from outside the housing 4 into the housing 4 through the air inlet 41 and sends it to the rotary device 6. The rotary device 6 uses its hygroscopic properties to absorb moisture from the air, thus drying the air. The dried air is then discharged from the air outlet, completing the basic process of air dehumidification. At the same time, the hot air circulation device 7 heats the circulating air to form a hot airflow. The hot airflow passes through the regeneration zone of the rotary device 6, carrying away some of the moisture in the rotary device 6. The hot air then enters the condenser. In the base 1 of the condenser, the hot airflow is first buffered. Because the base 1 has a folded corrugated partition plate 12 and a large air inlet cavity 111, the residence time of the hot airflow in the base 1 is extended, making the flow rate of the hot airflow more suitable for the subsequent condensation process.

[0052] Next, the hot circulating airflow enters the first condenser tube 31 in the condensation assembly 3. Because there are many first condenser tubes 31, at the same flow rate, the hot circulating airflow slows down, the flow path becomes more complex, and the total surface area increases when flowing through the first condenser tubes 31. The hot circulating air stays in the first condenser tubes 31 for a longer time, allowing heat to dissipate fully and a large amount of moisture to condense. Afterward, the hot circulating air enters the second condenser tube 32 for further optimized condensation.

[0053] During the condensation process, water droplets condensed in the first condenser tube 31 and the second condenser tube 32 drip down to the bottom of the air inlet chamber 111 and the air outlet chamber 112 respectively under the action of gravity. Then, they flow into the water storage tank 8 through the first flow pipe 15 and the second flow pipe 16 at the bottom of the base 1, respectively. This prevents condensate from accumulating inside the device, thus avoiding problems such as affecting the condensation effect or causing bacterial growth. The humidity of the hot circulating air after treatment by the condensation device is significantly reduced, completing the regeneration process of the rotary dehumidifier 6. This ensures that the rotary dehumidifier 6 continuously and stably dehumidifies the intake humid air, ultimately achieving the goal of effectively reducing indoor air humidity and creating a comfortable living environment for users. Throughout the process, all components of the rotary dehumidifier work together, significantly improving dehumidification performance compared to traditional rotary dehumidifiers and meeting people's needs for a comfortable indoor environment.

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