As shown in fig. 1 and 2, the moisture drying device includes a flow path housing 10 and a blower 20, a flow path is formed in the flow path housing 10, a fluid inlet 111 and a return port 112 are provided on the flow path housing 10, and the fluid inlet 111 and the return port 112 are both used for communicating with a cavity to be dried (in this embodiment, a liner) storing moisture. As shown in fig. 3, a flow channel is formed in the flow channel shell 10, the flow channel includes a cooling flow channel 101 and a return flow channel 102 which are communicated, a head end of the cooling flow channel 101 is connected with a fluid inlet 111, a tail end of the return flow channel 102 is connected with a return flow port 112, and the fan 20 is arranged in the return flow channel 102, specifically, one end of the return flow channel 102 connected with the cooling flow channel. The fan 20 can drive the gas in the liner to enter the cooling flow passage through the fluid inlet 111, the gas is cooled in the cooling flow passage and condensed to obtain condensed water, and the drier gas enters the backflow flow passage 102 through the fan 20 and returns to the liner through the backflow port 112.

In this embodiment, after the humid air in the liner is introduced into the flow channel, the humid air flows in the cooling flow channel 101 first, and is cooled during the flowing process, so that the moisture in the humid air is condensed into condensed water; the lower humidity gas continues along the cooling flow path 101 and through the fan 20 into the return flow path 102 and back into the liner through the return port 112. The gas with higher humidity in the inner container enters the flow channel for cooling, the gas with lower humidity returns to the inner container, and the inner container can be dried by circulating the steps. The humid air is firstly cooled in the cooling flow passage 101 to reduce the humidity, and then enters the return flow passage 102 in contact with the fan 20, so that the contact between the humid air and the fan 20 can be reduced, and the failure rate of the fan 20 can be reduced.

In this embodiment, the fan 20 is located in the flow channel, and can play a role of protecting the fan 20 through the flow channel shell 10, so as to avoid the fan 20 from colliding with or being influenced by external environment to fail.

Since the axial dimension of the fan 20 is generally smaller than the radial dimension of the fan 20, in order to reduce the dimension of the runner casing 10, the part of the runner in this embodiment is configured as a double-layer structure, the fan 20 is disposed at the double-layer position, so that the axis of the fan 20 extends along the thickness direction of the runner casing 10, the axial end face of the fan 20 is air-fed, and the circumferential surface of the fan 20 is air-discharged, so that the space in the runner is fully utilized, the thickness of the runner casing 10 is reduced, and the dimension of the runner casing 10 is reduced.

Specifically, the end of the cooling flow path 101 and the head end of the return flow path 102 are stacked and communicate in the thickness direction of the flow path case 10, and the fan 20 is disposed at the head end of the return flow path 102. Wherein, the axial end face of the fan 20 is used for air inlet, and the circumferential surface of the fan 20 is used for air outlet.

Specifically, the housing includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are connected in the thickness direction of the flow path housing 10 and enclose a flow path. A partition 14 is provided between the first housing 11 and the second housing 12 to partition a part of the space within the casing into a double-layered structure.

To avoid the condensed water condensed in the cooling flow path 101 from contacting the blower 20, the blower 20 is higher than the bottom end of the cooling flow path 101. That is, in the process that the air flow flows from the cooling flow channel 101 to the fan 20, a region where the air flow flows from bottom to top exists, so that condensed water in the cooling flow channel 101 can be gathered at the bottom end of the cooling flow channel 101 under the action of gravity without contacting with the fan 20. As shown in fig. 3 and 4, the return flow passage 102 communicates with the middle portion of the cooling flow passage 101 to prevent condensed water from entering the return flow passage 102.

To enhance the cooling effect of the moisture in the liner within the cooling flow channel 101, at least a portion of the cooling flow channel 101 is curved to extend the flow path of the moisture within the cooling flow channel 101. In this embodiment, the cooling flow path 101 includes a detour section 1011 and an introduction section 1012, one end of the detour section 1011 communicates with the fluid inlet 111, the other end is connected to the introduction section 1012, and the introduction section 1012 extends to the partition 14 to communicate with the communication port 141 on the partition 14.

As shown in fig. 3 and 4, the detour section 1011 extends from top to bottom in a curved manner, the introduction section 1012 communicates with the detour section 1011, and the communication position of the introduction section 1012 and the detour section 1011 is spaced from the bottom end of the detour section 1011. By the arrangement, condensed water condensed in the detour section 1011 can be gathered at the bottom end of the detour section 1011, so that the probability that moisture enters the introduction section 1012 along with the airflow is reduced, the humidity of the air entering the reflux flow passage 102 is reduced, and the contact between the moisture and the fan 20 is reduced.

The roundabout section 1011 comprises a plurality of branch flow channel sections which are arranged at an included angle, the branch flow channel sections are sequentially connected, and the air flow is contacted with the inner wall of the flow channel to change the flow direction in the process of flowing from the current branch flow channel section to the next branch flow channel section. In the process, the moisture in the air flow is easy to condense and gather on the inner wall of the flow channel, which is beneficial to promoting the separation of air and liquid.

In this embodiment, the branch flow channel sections linearly extend, and two adjacent branch flow channel sections are vertical, and are respectively a horizontal flow channel section and a vertical flow channel section. The flow directions of the air flows in the two adjacent horizontal flow channel sections are opposite, so that the plurality of horizontal flow channel sections are vertically arranged, and the size of the detour section in the horizontal direction is reduced.

In other embodiments, the flow direction of the air flow in two adjacent horizontal flow channel sections can be the same, and the tortuous flow of the air flow in the detour sections is not affected.

In other embodiments, the branch channel section may extend in a curved manner, and may also extend the length of the detour section, so as to facilitate moisture condensation.

In other embodiments, at least part of the branch channel sections can also extend obliquely relative to the horizontal direction, the detour section comprises the branch channel sections extending obliquely, and the detour section can realize the detour flow of the air flow in the detour section by matching with the branch channel sections extending horizontally or the branch channel sections extending vertically.

In order to form the detour section 1011, a plurality of partition plates 16 are arranged in the flow channel at intervals, and the partition plates 16 and the housing form the detour section 1011, so that the air flow in the flow channel needs to bypass the plurality of partition plates 16 in turn to flow in a curved manner. As shown in fig. 3, the partition 16 extends horizontally, and the partition 16 abuts against the first housing 11 and the second housing 12, respectively, to change the flow direction of the fluid.

In order to further extend the flow path of the fluid in the detour section 1011, the plurality of baffles 16 are staggered, so that the flow directions of the fluid on both sides of the same baffle 16 are opposite, the flow directions of the fluid between two adjacent baffles 16 are the same, and the flow direction of the fluid is turned back when flowing to the free end position of the baffle 16, thereby being beneficial to condensation and separation of the liquid.

In some embodiments, the plurality of partitions 16 may be disposed opposite to each other in the vertical direction, or may fold the airflow back between two adjacent partitions 16, so as to extend the flow path of the airflow.

In order to further improve the cooling effect of the air flow in the cooling flow channel 101, the flow channel shell 10 is provided with a cooling water inlet 113 and a cooling water outlet 114, the cooling water inlet 113 is used for introducing cooling water into the cooling flow channel 101, and the cooling water outlet 114 is used for discharging the cooling water in the cooling flow channel 101. By injecting cooling water into the cooling flow passage 101, the temperature of the fluid can be reduced by heat exchange between the cooling water and the fluid, so that water in the fluid can be condensed, thereby realizing gas-liquid separation.

In the present embodiment, both the cooling water inlet 113 and the cooling water outlet 114 communicate with the cooling flow passage 101. Namely, the cooling water is directly communicated into the cooling flow channel 101 to be in contact with the air flow for heat exchange, thereby being beneficial to simplifying the structure and improving the heat exchange effect.

In order to improve the water condensation effect, a water storage tank is provided in the cooling flow passage 101, and the water storage tank is used for storing cooling water. By providing the water storage tank, a certain amount of cooling water can be always provided in the cooling flow passage 101, so that the condensing effect on the fluid can be ensured.

Further, a water storage tank is provided in the detour section 1011. The air flow flows in the detour section 1011 for a long time and along a long path, and the cooling effect of the cooling water on the air flow can be improved by providing the water storage tank in the detour section 1011.

In order to ensure that fluid flowing in the roundabout section 1011 can exchange heat with and cool down the cooling water, a water storage groove is arranged in each horizontal flow passage section, so that the fluid can exchange heat with the cooling water when passing through each horizontal flow passage section, thereby condensing moisture in the fluid and improving the drying effect of the air flow.

In other embodiments, only a portion of the horizontal channel segments may be provided with a water reservoir, or both a portion of the horizontal channel segments and a portion of the vertical channel segments may be provided with a water reservoir, or only all or all of the vertical channel segments may be provided with a water reservoir, or both all of the horizontal channel segments and all of the vertical channel segments may be provided with a water reservoir. The above-mentioned modes can be cooled by the cooling water in the water storage tank for the passing air flow so as to dry the air flow.

The depth of the reservoir depends on the height of the water retaining flap 17.

In other embodiments, the top surface of the baffle 16 may be concave to form a reservoir, and in such a configuration the baffle 16 has a thickness to ensure that the reservoir has a depth.

As shown in fig. 3, the cooling water inlet 113 is disposed at the top end of the roundabout section 1011, and the cooling water outlet 114 is disposed at the bottom end of the roundabout section 1011, so as to drive the cooling water to flow from the top end to the bottom end of the roundabout section 1011 by gravity, and the cooling water flowing in the cooling flow channel 101 is beneficial to heat exchange between the cooling water and the air flow, thereby improving the condensing effect of the moisture in the air flow and improving the drying degree of the discharged air flow.

In order to allow cooling water to enter each water storage tank, a certain amount of cooling water is always arranged in each water storage tank, and projection parts of two adjacent partition plates 16 in the horizontal plane are overlapped. As shown in fig. 3, when cooling water enters the top end of the detour section 1011 from the cooling water inlet 113, the cooling water enters the water storage tank formed by the uppermost partition plate 16, and as the water level in the water storage tank increases, the cooling water overflows from one end of the water storage baffle 17 connected to the partition plate 16, and the overflowed cooling water flows downward under the action of gravity and enters the water storage tank formed by the lower partition plate 16. By analogy, the cooling water gradually fills each water storage tank and is discharged from the cooling water outlet 114 after flowing continuously.

In order to improve the contact effect of the cooling water and the fluid, the cooling water inlet 113 can be further provided with an atomization assembly, the atomization assembly can enable the cooling water entering the cooling flow channel 101 to be sprayed out in a tiny mist form, the atomized cooling water is more dispersed and is in close contact with the flowing air flow, the heat exchange efficiency is increased, and the condensation effect is achieved.

In order to reduce the use cost, the cooling water can be tap water, namely, the cooling water inlet 113 is connected with a faucet, and a cold water source in a kitchen environment is used as a heat exchange cooling medium, so that the cost is low and the structure is simple.

In some embodiments, the moisture drying apparatus further comprises a water tank for storing tap water and a water pump for driving the liquid in the water tank to circulate in the water tank and the cooling flow passage 101, wherein the cooling water inlet 113 and the cooling water outlet 114 are both communicated with the water tank.
