Description

a water divider

technical field

The invention relates to a water separator structure, in particular to a water separator used on an air-conditioning mattress host to divert water to a water curtain for evaporation.

Background technique

The air-conditioning mattress is a kind of multi-functional cooling and heating dual-purpose mattress with microcomputer automatic temperature control. The heat medium water is introduced into the cushion body of the air-conditioning mattress through the soft pipe to provide cold or heat for the cushion body of the air-conditioning mattress, which has high efficiency, safety and reliability.

Among them, the generation of cold working medium needs to distribute the water flowing back from the pad to the water curtain through the water separator in the host machine, and in the process of the water flowing down the water curtain, under the action of the airflow generated by the fan, it evaporates rapidly and brings Taking a lot of heat, the temperature of the water flowing down the water curtain drops rapidly to become refrigerant water, which is finally transported to the pad body of the air-conditioning pad. During this process, the temperature of the generated refrigerant water depends on whether the water separator can evenly divide the water And directly related to the speed of water separation.

The existing water separator generally includes a water separator cavity, the water inlet of the water separator cavity communicates with the heat exchange tube of the pad body through a pipeline, and the water in the pad body is input into the water separator by a water pump, and the water separator The bottom wall is longitudinally provided with a water outlet, and there is no barrier between the water inlet and the water outlet. After the water enters from the water inlet, it flows directly to the water outlet, and from the water outlet to the water curtain. According to the principle of water flow, the water flows from After the water inlet enters the water separator, it is mainly concentrated at the water outlet near the water inlet and flows down to the water curtain. Therefore, the water curtain corresponding to the area closer to the water inlet gets more water, and vice versa. It will cause the water flowing down the water curtain to be locally concentrated and unevenly distributed, which will affect the evaporation effect.

Contents of the invention

The purpose of the present invention is to provide a water separator with more uniform water separation, so as to improve the evaporation effect of the water curtain of the air-conditioning mattress host.

A water separator according to the present invention includes a water separator cavity, and a plurality of drainage holes are uniformly arranged on the bottom surface of the water separator cavity, and a water inlet hole is arranged on one side of the water separator cavity. A water retaining plate is set between the water hole and the drain hole to separate them; a water retaining wall is arranged around the drain hole, and narrow water inlet gaps are evenly spaced on the water retaining wall.

In the water separator according to the present invention, after the water flow enters the cavity through the water inlet hole, it is blocked by the baffle, and flows into the space formed by the water retaining wall and the cavity wall from the front and rear sides of the baffle, and then passes through the water retaining wall. The narrow water inlet gaps arranged at intervals on the wall enter the space in the water-retaining wall, and then discharge through the evenly arranged drainage holes in the water-retaining wall.

Due to the blocking of the baffle, the water flow is prevented from directly entering the nearby drainage hole; at the same time, due to the narrow water inlet gap set on the water retaining wall, the water flow will be subject to greater resistance when passing through the water inlet gap, so it enters the water retaining wall The water flow in the space formed with the cavity wall will quickly fill the entire space between the water retaining wall and the cavity wall before flowing through the water inlet gap and entering the inner side of the water retaining wall, which can well ensure the water flow into the space. The synchronicity of each water inlet gap. The synchronization of the water flow entering the water retaining wall is guaranteed, and the uniformity of the water flow entering the drainage hole is also ensured, thereby ensuring the uniformity of the water distribution of the water separator.

Detailed ways

As shown in Figures 1 to 5, the water separator includes a water separator cavity 1 installed in the box body 100 of the air conditioner main unit, and a plurality of drainage holes are uniformly arranged on the bottom surface of the water separator cavity 1 12. A water inlet 11 is provided on one side of the water distributor cavity. The water inlet 11 communicates with the heat exchange tube (not shown in the figure) in the cushion body of the air-conditioning mattress through the water pipe 400. The top of the water curtain 200 is connected to the The water separator cavity 1 is in contact with the bottom surface, and the lower part is offset against the water pan of the water tank 300. A water barrier is set between the water inlet hole 11 and the drain hole 12 to separate them; a water retaining wall is set around the drain hole , There are narrow water inlet gaps evenly spaced on the water retaining wall. After the water flow enters the cavity through the water inlet hole, it is blocked by the baffle, and flows into the space formed by the water retaining wall and the wall of the cavity from the front and rear sides of the baffle, and then passes through the narrow water inlet on the water retaining wall. The gap enters the space in the water-retaining wall, and then is discharged through the drainage holes evenly arranged in the water-retaining wall.

Due to the blocking of the baffle, the water flow is prevented from directly entering the nearby drainage hole; at the same time, due to the narrow water inlet gap set on the water retaining wall, the water flow will be subject to greater resistance when passing through the water inlet gap, so it enters the water retaining wall The water flow in the space formed with the cavity wall will quickly fill the entire space between the water retaining wall and the cavity wall before flowing through the water inlet gap and entering the inner side of the water retaining wall, which can well ensure the water flow into the space. The synchronicity of each water inlet gap. The synchronization of the water flow entering the water retaining wall is guaranteed, and the uniformity of the water flow entering the drainage hole is also ensured, thereby ensuring the uniformity of the water distribution of the water separator. The water separator evenly flows out the water, that is, the water volume of the water curtain at the bottom is uniform, so as to make full use of the evaporation area of each part of the water curtain and improve the evaporative cooling effect of the air-conditioning mattress main unit.

In the present invention, in order to make the amount of water entering the water retaining wall 3 on the side close to the water inlet 11 and the side away from the water inlet 11 uniform, the water inlet gap 31 needs to be made very narrow, and through the narrow and elongated water inlet gap 31, Sufficient resistance to water flow is provided, so that the water flows flowing through the water inlet slots 31 are synchronized. However, the narrow and elongated water inlet gap 31 has brought technical difficulties to the processing of the water retaining wall. For the consideration of simplifying the processing, the water inlet slit on the water retaining wall can be made wide, and the water comb teeth 32 with a height lower than the water retaining wall are set at the bottom of each water inlet slit. Due to the increased water inlet gap, the processing of the water retaining wall 3 is simpler; at the same time, it subtly divides the larger water inlet gap into comb water teeth 32 arranged at the bottom of the water inlet gap 31. The narrow gaps on both sides of the teeth ensure the resistance of water ingress well, and can still meet the synchronization requirements of water flow into the water-retaining wall. In addition, the height of the water-combing teeth 32 is shorter than that of the water-retaining wall 3, and a wider gap is formed between the upper part of the water-combing teeth 32 and the water-retaining wall 32. It enters into the water retaining wall, so that it can be discharged through the drainage holes faster to ensure smooth drainage.

The drain holes 12 evenly arranged in the water retaining wall 3 can be only one row, two rows, three rows, or even more. The more rows there are, the more even the water will be divided.

The drain holes 12 evenly arranged in the water retaining wall 3 are also provided with grades of different heights, two grades, three grades, or even more grades, and the drain holes 12 of the same height grade are also evenly distributed in the water retaining wall. Through the drainage holes 12 with multiple grades and different heights, the drainage holes 12 can be adapted to the water diversion requirements of different inflow flows. When the water inflow is small, the discharge through the drain holes of the lowest level can meet the drainage demand; and when the water inflow increases, the drain holes of the lowest level can not discharge the water entering the cavity, the water level in the water retaining wall It will gradually rise until the drain hole of a higher level is put into drainage, so that the drainage flow is compatible with the water intake flow. If it is still not satisfied, drain the water through the drainage hole of a higher grade. It can adapt to the use requirements of different water flow rates through the setting of multi-level drain holes, so that the load of the air-conditioning mattress main unit can be adjusted, so that the air-conditioning mattress main unit can adapt to the needs of different cooling capacities.

The water retaining plate 2 provided between the water inlet hole 11 and the drain hole 12 is preferably extended upward to the top surface of the cavity 1, which can reliably prevent the water entering from the water inlet hole 11 at a relatively high speed from directly crossing the water retaining plate. The plate 11 enters into the water retaining wall 3 .

The bottom surface of the water distributor cavity 1 is provided with a boss that is penetrated by the drain hole, and the lower end of the boss contacts the water curtain, which can limit the water curtain, and at the same time, can prevent the drain hole 12 from being blocked.

The edge of the bottom surface of the water distributor cavity 1 is provided with a flange 13 extending downward, and a space for the upper part of the water curtain 200 to be inserted and matched is formed in the flange 13, and the upper part of the water curtain is limited. The flange 13 is inclined inwardly from top to bottom, which can better cooperate with the water curtain 200 and at the same time guide part of the water sliding down the inner wall of the flange 13 to the water curtain 200 to avoid water dripping into the accumulated water off-board.

The bottom surface of the water distributor can also be provided with a frame 14 extending downwards, and the frame frames each boss in it, and its bottom is against the top edge of the water curtain, and can be pressed on the top edge of the water curtain. The frame can prevent the water from overflowing to the outside of the water curtain when the water flow flowing down from the water separator is relatively large, thereby further reducing the possibility of water leakage from the main unit of the air-conditioning mattress.
