In some embodiments of the present invention, the present invention further comprises a flow guiding element 400 disposed between the evaporator 300 and the water pipe 200, the flow guiding element 400 is provided with an overflow port 411 and a connection port 412, the flow guiding element 400 is configured to guide the condensed water to flow from the connection port 412 toward the overflow port 411, and the water replenishing port 201 is communicated with the connection port 412.

In this embodiment, the water replenishing port 201 of the water pipe 200 is indirectly communicated with the drain hole of the evaporator 300 through the flow guide 400. Specifically, the flow guide member 400 is specifically connected to the outside of the bottom of the evaporator 300, and in order to guide the condensed water, the flow guide member 400 should be a member having a water flow restriction function, for example, the flow guide member 400 may be a closed pipe, a groove with an open top, a structure having a flow passage inside, or the like. The flow guide 400 is arranged to guide the condensate to flow from the connection opening 412 in the direction of the overflow 411, i.e. the condensate should first flow through the connection opening 412 and then through the overflow 411. The water pipe 200 is communicated with the connection port 412 on the flow guide member 400, and the communication mode between the water pipe 200 and the connection port 412 on the flow guide member 400 may also be direct communication, for example, one end of the water pipe 200 having the water replenishing port 201 is directly contacted with the flow guide member 400, or the water pipe 200 and the flow guide member 400 are connected through other pipelines, or may also be indirect communication, for example, the water replenishing port 201 of the water pipe 200 is placed below the water drain port, and the condensed water discharged from the water drain port drops into the water replenishing port 201.

In this embodiment, the diversion member 400 is arranged to guide the condensed water to flow from the connection port 412 to the overflow port 411, and before the water pipe 200 is filled with water, all or at least most of the condensed water enters the water pipe 200 through the connection port 412; when the water pipe 200 is filled with water, which means that the generating speed of the condensed water is higher than the consumption speed of the water in the water tank 110, the excess condensed water will continue to flow to the overflow port 411 for discharging; when the water in the water tank 110 is consumed and the water pipe 200 is not filled with water, the condensed water preferentially flows into the water pipe 200 from the connection port 412 again.

In some embodiments of the present invention, the diversion member 400 includes an inclined diversion trench 410, the overflow port 411 and the connection port 412 are both disposed on a trench wall of the diversion trench 410, and the height of the connection port 412 is higher than the height of the overflow port 411, and the position where the condensed water flows into the diversion trench 410 is located at an end of the diversion trench 410 having the connection port 412 and higher than the connection port 412.

Referring to fig. 4, the guide member 400 includes an inclined guide groove 410 and an inclined water storage groove 420 connected to the guide groove 410, the guide groove 410 and the water storage groove 420 form a V-shaped structure to adapt to the bottom shape of the evaporator 300, and meanwhile, the condensate that is not discharged in the future is temporarily stored at the junction of the guide groove 410 and the water storage groove 420. The overflow port 411 and the connection port 412 are both disposed on the wall of the diversion trench 410, and the height of the connection port 412 is higher than that of the overflow port 411. The overflow opening 411 may be disposed at the lowest portion of the guiding gutter 410 and located on the walls of the guiding gutter 410 and the storage gutter 420, respectively, as shown in fig. 4. In this embodiment, the drain hole of the evaporator 300 is not disposed at the lowest position of the evaporator 300, but is slightly higher than the lowest position, so that when the flow guide member 400 is assembled, the position where the condensed water flows into the flow guide groove 410 is located at the end of the flow guide groove 410 having the connection port 412 and is higher than the connection port 412.

In this embodiment, the obliquely arranged guiding groove 410 has the function of guiding the condensed water to sequentially flow through the connecting port 412 and the overflow port 411, and can fit the appearance of the evaporator, thereby being beneficial to reducing the overall volume of the guiding element 400 connected with the evaporator 300.

It will be appreciated that the diversion element 400 may be provided without the reservoir 420, but instead with the downwardly facing end of the diversion channel 410 closed, which would also serve to temporarily store condensate that has not been drained.

In some embodiments of the present invention, the water pipe 200 is further provided with an overflow port, and the height of the overflow port is higher than the height of the water outlet 202 and lower than the height of the water replenishing port 201.

In this embodiment, the diversion element 400 may not be provided, the water pipe 200 is directly communicated with the drain hole of the evaporator 300, and an overflow port is provided on the water pipe 200 between the water replenishing port 201 and the water outlet 202, and the height of the overflow port is higher than that of the water outlet 202 and lower than that of the water replenishing port 201. An overflow port may be provided on the upwardly facing wall of the water tube 200 to reduce or eliminate the amount of water overflowing the overflow port during the flow of condensate to the water tank 110.

In this embodiment, by providing the overflow port on the water pipe 200, all or at least most of the condensed water enters the water tank 110 before the liquid level in the water pipe 200 is lower than the overflow port; when the liquid level in the water pipe 200 is higher than the overflow port, which means that the generation rate of the condensed water is higher than the consumption rate of the water in the water tank 110, the excessive condensed water is discharged from the overflow port.

In some embodiments of the present invention, the present invention further includes a valve body 510 and a floating ball 520, the valve body 510 is connected to the water pipe 200 and is located between the connection port 412 and the water inlet 111, a cavity 511 is disposed in the valve body 510, the cavity 511 is communicated with the connection port 412 through a first opening 512 on the valve body 510 and is communicated with the water inlet 111 through a second opening 513 on the valve body 510, the first opening 512 is smaller than the second opening 513, and the floating ball 520 is located in the cavity 511 and can rise to a set height along with the liquid level in the cavity 511 to block the first opening 512.

Referring to fig. 4, 5 and 6, fig. 5 shows a front view of the oxygen removing module in fig. 4, fig. 6 shows a cross-sectional view of a-a in fig. 5, in this embodiment, the valve body 510 is located between the flow guide 400 and the water pipe 200, specifically, a connecting pipe 530 is further connected to an outer side of the valve body 510, and the connecting pipe 530 extends toward an end of the valve body 510 having a first opening 512 and is sleeved on a joint 430 of the flow guide 400 communicating with the connection port 412, that is, the first opening 512 substantially communicates with the connection port 412 through the connecting pipe 530. The end of the water pipe 200 having the water replenishing port 201 is sleeved outside the connection pipe 530, i.e. the second opening 513 is substantially communicated with the water inlet 111 through the water pipe 200. A cavity 511 is arranged in the valve body 510, and the floating ball 520 is positioned in the cavity 511. When water exists in the cavity 511, the floating ball 520 floats on the water surface and can rise synchronously along with the rise of the liquid level, and after the floating ball 520 rises to a set height, the floating ball 520 blocks the first opening 512, so that the water path between the connecting port 412 and the water inlet 111 can be disconnected. In order to facilitate the floating ball 520 to block the first opening 512 and guide the floating ball 520, the valve body 510 may be tapered, that is, the diameter of the valve body 510 gradually decreases from the second opening 513 to the first opening 512, so that the first opening 512 is smaller than the second opening 513.

Because water pipe 200 and water tank 110 intercommunication, the working solution (for example electrolyte etc.) in the water tank can spread to the water pipe 200 in, and partial working solution will be taken away when the water in the water pipe 200 overflows fully, can lead to the concentration reduction of working solution after long-time, influences work efficiency. In this embodiment, the valve 510 and the floating ball 520 are disposed between the flow guide member 400 and the water pipe 200, so that the water path between the connection port 412 and the water inlet 111 is cut off after the liquid level in the water pipe 200 reaches a predetermined height, thereby preventing the working fluid in the water tank 110 from escaping.

It will be appreciated that the valve body 510 and the float 520 may be disposed at other positions, such as between the water pipe 200 and the water tank 110, or at the middle portion of the water pipe 200, in which case the water pipe 200 actually includes a pipeline between the valve body 510 and the guide 400, and a pipeline between the valve body 510 and the water tank 110.

In some embodiments of the present invention, the present invention further comprises a flow guiding element 400 disposed between the evaporator 300 and the water pipe 200, the flow guiding element is provided with a water storage cavity for receiving condensed water discharged from the water outlet, the wall of the water storage cavity is provided with an overflow port 411 and a connection port 412, the height of the overflow port 411 is higher than that of the connection port 412, and the water replenishing port 201 is communicated with the connection port 412.

The overflow opening 411 and the connection opening 412 are arranged on the wall of the reservoir cavity, the height of the overflow opening 411 is higher than that of the connection opening 412, for example, the connection opening 412 may be arranged at the intersection of the diversion trench 410 and the reservoir 420, that is, the lowest position of the diversion member 400, the overflow opening 411 may be arranged on the wall of the diversion trench 410 or the wall of the reservoir 420, and the water replenishing opening 201 is communicated with the connection opening 412.

In this embodiment, the height of the overflow port 411 is higher than that of the connection port 412, that is, when the water in the water pipe 200 overflows, the water is discharged from the overflow port 411 after a certain height is accumulated in the water storage cavity, that is, a certain amount of water can be accumulated in the water storage cavity to be used as a water supplement source for the water tank 110.
