Description

Technical Field

[0001] The present application relates to the field of ventilation technology, and in particular to a ventilation device for an indoor swimming pool. Background Art

[0002] As a modern sports facility, indoor swimming pools not only provide people with a comfortable swimming environment, but also become an important part of various public buildings and private residences. However, due to the water vapor generated by the continuous evaporation of the pool water surface, as well as the body odor and heat brought by the swimmers' activities, the air quality of indoor swimming pools is often poor, with problems such as high humidity and polluted air. These problems not only affect the swimming experience of tourists, but may also cause damage to the building structure. Therefore, reasonable and effective ventilation devices have become an indispensable and important equipment for indoor swimming pools.

[0003] At present, most of the common indoor swimming pool ventilation devices on the market use mechanical ventilation to discharge indoor polluted air and introduce outdoor fresh air at the same time. However, this mechanical ventilation method is easy to introduce hot air from the outside in summer, causing the indoor temperature to continue to rise and the evaporation of swimming pool water to accelerate. In winter, it is also easy to draw out the moist hot air in the room and introduce dry cold air from the outside, causing the indoor temperature to continue to drop and the humidity to be insufficient. In particular, there is a significant temperature difference between the air inlet and other areas of the room. For this reason, many indoor swimming pools will install air conditioners to cooperate with mechanical ventilation for cooling and heating. However, large indoor swimming pools require more air conditioners to be installed, and when mechanical ventilation continuously introduces outside air, the air conditioner needs to work at high power to further maintain the comfort of the indoor air, which increases the use cost and maintenance cost. In this process, the indoor air is easily prone to rapid drop in humidity due to the discharge and introduction of mechanical ventilation, as well as the air exchange during cooling and heating of the air conditioner, resulting in the problem of excessive dryness of the indoor air, affecting the overall comfort. Summary of the invention

[0004] The present application proposes an indoor swimming pool ventilation device, which has the advantages of heat exchange between indoor air and outdoor air at the heat exchange plate, moisture in the indoor air condenses on the heat exchange plate and falls down to form a water curtain, and the outdoor air is moistened by the water curtain and then discharged into the room, and the heat exchange plate floats up and down under multi-directional forces to disturb the air and improve the heat exchange effect, and the heat exchange plate squeezes the spring to make the spring hit the surrounding liquid to increase the gas-liquid contact area, so as to solve the problems of rapid indoor temperature drop and rise, dry indoor air and high air conditioning cost caused by the existing indoor swimming pool ventilation device.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an indoor swimming pool ventilation device, including an exchange pipe, one side of the exchange pipe is provided with an air inlet, and the other side is provided with an air outlet for input and output of indoor air, an exchange chamber is provided in the exchange pipe, a heat exchange device is arranged in the exchange chamber, a mounting port is provided at the top of the exchange chamber, a connecting port I is provided at the bottom of the exchange chamber, and a humidifying chamber is provided at the bottom of the exchange pipe; the heat exchange device includes a liquid distribution plate, an air inlet pipe, a hollow rubber and a heat exchange plate, the liquid distribution plate is arranged at the mounting port, and an air transmission port is provided in the liquid distribution plate The duct is connected with the air inlet duct and the inner cavity of the hollow rubber. A heat exchange inner chamber is provided in the heat exchange plate and is connected with the inner cavity of the hollow rubber, which is used to introduce outside air into the heat exchange plate for heat exchange. The heat exchange plate is provided with uniformly distributed heat exchange air ducts for heat exchange between indoor air and outdoor air. A connecting port II is provided at the top of the inner cavity of the humidifying chamber and is connected with the connecting port I. The inner cavity of the humidifying chamber is provided with a drainage slope. An exhaust port is provided at one end of the humidifying chamber away from the liquid collection chamber. The bottom end of the heat exchange plate is open, and the bottom end of the heat exchange plate is located on the drainage slope, which is used to introduce liquid and gas on the heat exchange plate into the humidifying chamber for humidification.

[0006] Preferably, a liquid collection chamber is opened in the humidifying chamber, a drain pipe is arranged at the bottom end of the liquid collection chamber, the drainage slope is inclined, and one end of the drainage slope close to the liquid collection chamber is at the lower end of the inclined surface, which is used to introduce the liquid dropped on the heat exchange plate into the liquid collection chamber.

[0007] Preferably, an elastic rubber is provided between the inner wall of the connecting port I and the outer wall of the heat exchange plate, an elastic rubber is provided between the bottoms of the opposite ends of the two heat exchange plates, and the elastic rubber connected between the two heat exchange plates and the elastic rubber connected at the connecting port I are in the same plane to avoid large-scale backflow of indoor air.

[0008] Preferably, the elastic rubber is provided with evenly distributed drainage holes on one side close to the heat exchange plate, so as to introduce the liquid on the heat exchange plate into the humidification chamber.

[0009] Preferably, the heat exchange air passage is inclined upward, so as to apply an upward force to the heat exchange plate when the indoor air passes through.

[0010] Preferably, evenly distributed springs are provided directly below the heat exchange plate, and the bottom ends of the springs are connected to the drainage slope to cooperate with the floating of the heat exchange plate and hit the surrounding liquid.

[0011] The present application provides an indoor swimming pool ventilation device, which, by arranging an exchange duct, allows the exhausted indoor air to enter the exchange chamber and then pass through the heat exchange plate, and the introduced outdoor air can also enter the heat exchange plate. On hot days, the indoor humid cold air passes through the heat exchange plate and will exchange heat with the outdoor hot air in the heat exchange plate, so that the hot air is cooled before being discharged into the room. On cold days, the indoor humid hot air passes through the heat exchange plate and will exchange heat with the outdoor cold air in the heat exchange plate, so that the hot air is heated before being discharged into the room, thereby reducing the temperature difference between the outside air introduced into the room and the indoor air, and reducing the use cost of the air conditioner.

[0012] At the same time, no matter whether it is humid cold air or humid hot air, when passing through the heat exchange plate for heat exchange, part of the moisture in the air will be intercepted by the heat exchange plate, condensed on the heat exchange plate, and gradually flow downward, forming a water curtain at the bottom of the heat exchange plate, increasing the humidity around the bottom of the heat exchange plate, and the outside air discharged from the bottom opening after heat exchange in the heat exchange plate will pass through the water curtain to obtain moisture, become moist and then be discharged into the room, thereby avoiding the problem of a large amount of dry air being discharged into the room, resulting in too low indoor air humidity.

[0013] In addition, when the outside air goes down in the heat exchange plate, it will exert a downward thrust on the heat exchange plate, causing the heat exchange plate to move downward. When the indoor air passes through the heat exchange air duct on the heat exchange plate, the heat exchange air duct is designed to be inclined upward, so that the indoor air exerts an upward thrust on the heat exchange plate. In this process, the downward moving heat exchange plate squeezes the spring below, and the spring compression exerts an upward thrust. The liquid condensed on the heat exchange plate will increase the overall weight of the heat exchange plate. However, the liquid is constantly leaving the heat exchange plate, causing the overall weight of the heat exchange plate to be in a constant change process. This also causes the heat exchange plate to float up and down under multiple forces, causing the heat exchange plate to disturb the surrounding indoor air and interfere with the normal flow of the inner outdoor air, increasing the turbulent state of the air and improving the heat exchange effect.

[0014] The up and down floating action of the heat exchange plate will cause the squeezed spring below to bounce up and down. At this time, the liquid on the heat exchange plate will fall rapidly under the floating action and be hit by the bouncing spring below, so that scattered water droplets are formed around the spring, increasing the contact area between the outside air introduced from the surrounding and the water, and improving the efficiency of the outside air obtaining moisture.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example 1

[0019] See also Figures 1 to 3 A ventilation device for an indoor swimming pool includes an exchange pipe 1, an exchange chamber 2 is provided in the exchange pipe 1, an air inlet 3 is provided on one side of the exchange pipe 1, so that indoor air can be introduced into the exchange chamber 2 through the air inlet 3, and an air outlet 4 is provided on the other side, so that the indoor air after heat exchange in the exchange chamber 2 can be discharged through the air outlet 4, a mounting port 5 is provided at the top end of the exchange chamber 2, and a connecting port Ⅰ 6 is provided at the bottom end, and the bottom end of the exchange pipe 1 is fixedly connected to a humidification chamber 7 by bolts.

[0020] See also Figures 1 to 3A connecting port II8 connected to the connecting port I6 is provided at the top of the inner cavity of the humidifying chamber 7, a liquid collecting chamber 11 is provided in the humidifying chamber 7, and a drain pipe 12 is fixedly connected to the bottom end of the liquid collecting chamber 11. A drainage slope 10 is provided in the inner cavity of the humidifying chamber 7, and the drainage slope 10 is inclined. The end of the drainage slope 10 close to the liquid collecting chamber 11 is at the lower end of the inclined surface, so that the liquid falling from the heat exchange plate 17 can fall on the drainage slope 10, and then flow into the liquid collecting chamber 11 along the drainage slope 10 for collection. When the water level in the liquid collecting chamber 11 is too high, the excess water can be drained away by opening the drain pipe 12. An exhaust port 9 is provided at the end of the humidifying chamber 7 away from the liquid collecting chamber 11, so that the outdoor air after heat exchange through the heat exchange plate 17 can enter the humidifying chamber 7 through the bottom opening of the heat exchange plate 17, and then be discharged to the room through the exhaust port 9.

[0021] See also Figures 1 to 4 The installation port 5 is fixedly connected with a liquid distribution plate 13 by bolts, and an air delivery channel 14 is provided in the liquid distribution plate 13. The top of the liquid distribution plate 13 is fixedly connected with an evenly distributed air intake pipe 15 connected to the air delivery channel 14, so that the outside air can be input into the air delivery channel 14 through the air intake pipe 15. The bottom end of the liquid distribution plate 13 is fixedly connected with two symmetrical hollow rubbers 16, and the bottom end of the hollow rubber 16 is fixedly connected with a heat exchange plate 17, and a heat exchange inner chamber 18 is provided in the heat exchange plate 17. The bottom end of the heat exchange plate 17 is open, so that the outside air in the air delivery channel 14 can pass through the inner chamber of the hollow rubber 16. The air in the heat exchange chamber 18 enters the heat exchange cavity, and is discharged through the opening at the bottom of the heat exchange plate 17 after heat exchange in the heat exchange chamber 18. The heat exchange plate 17 is provided with evenly distributed heat exchange air ducts 19, so that the heat exchange chamber 18 forms a fork around the heat exchange air duct 19, which improves the spatial multidirectionality of the heat exchange chamber 18, and makes the outside air in the heat exchange chamber 18 collide, disperse and turn at the fork, thereby improving the turbulent state of the outdoor air and the heat exchange effect. At the same time, the indoor air introduced into the exchange chamber 2 will pass through the heat exchange air duct 19 to perform efficient heat exchange with the outside air in the heat exchange chamber 18.

[0022] See also Figure 2 , Figure 4 , Figure 6, the bottom of the heat exchange plate 17 passes through the connecting port Ⅰ6 and the connecting port Ⅱ8 to the top of the drainage slope 10. No matter whether it is humid cold air or humid hot air passing through the heat exchange plate 17 for heat exchange, part of the moisture in the air will be intercepted by the heat exchange plate 17, condensed on the heat exchange plate 17, and gradually flow downward, forming a water curtain at the bottom of the heat exchange plate 17 and falling on the drainage slope 10. The flow of liquid will increase the humidity around the bottom of the heat exchange plate 17, and the outside air in the heat exchange inner chamber 18 can enter the humidification chamber 7 through the opening at the bottom after heat exchange, and will obtain moisture through the water curtain and be discharged into the room after becoming humid, thereby avoiding the problem of a large amount of dry air being discharged into the room and causing the indoor air humidity to be too low. An elastic rubber 20 is fixedly connected to the inner wall of the connecting port Ⅰ6, and one end of the elastic rubber 20 close to the heat exchange plate 17 is fixedly connected to the outer wall of the heat exchange plate 17. The bottoms of the opposite ends of the two heat exchange plates 17 are fixedly connected with elastic rubber 20. The elastic rubber 20 connected between the heat exchange plates 17 and the elastic rubber 20 connected at the connecting port Ⅰ6 are in the same plane, so that the inner cavities of the exchange chamber 2 and the humidifying chamber 7 can be isolated by the elastic rubber 20 and the heat exchange plate 17, so as to avoid a large amount of indoor air being directly input from the exchange chamber 2 into the humidifying chamber 7, which would cause a large amount of original indoor air to flow back. The elastic rubber 20 is provided with evenly distributed drainage holes 21 on one side close to the heat exchange plate 17, so that the liquid on the heat exchange plate 17 will first slide on the elastic rubber 20 when falling. Due to the gravity of the heat exchange plate 17 itself, the downward squeezing force of the external air descending inside, and the weight of the condensed water, the heat exchange plate 17 will move downward. At this time, the heat exchange plate 17 will pull the elastic rubber 20 to tilt to one side of itself, so that the liquid on the elastic rubber 20 will be able to be discharged to the humidifying chamber 7 below through the drainage holes 21, and a part of it will be attracted by the heat exchange plate 17 and slide down along the plate surface of the heat exchange plate 17. Example 2

[0023] See also Figures 4 to 5On the basis of the first embodiment, the heat exchange air duct 19 is inclined upward, and a uniformly distributed spring 22 is arranged directly below the heat exchange plate 17. The bottom end of the spring 22 is fixedly connected to the drainage slope 10. When the outside air goes down in the heat exchange plate 17, it will exert a downward thrust on the heat exchange plate 17, so that the heat exchange plate 17 moves downward. When the indoor air passes through the heat exchange air duct 19 on the heat exchange plate 17, due to the design of the heat exchange air duct 19 being inclined upward, the indoor air exerts an upward thrust on the heat exchange plate 17. In this process, the downward movement The moving heat exchange plate 17 squeezes the spring 22 below. The compression of the spring 22 creates an upward thrust, and the condensed liquid on the heat exchange plate 17 increases the overall weight of the heat exchange plate 17. However, the liquid is constantly leaving the heat exchange plate 17, so that the overall weight of the heat exchange plate 17 is in a constant changing process, which causes the heat exchange plate 17 to float up and down under multiple forces, causing the heat exchange plate 17 to disturb the surrounding indoor air and interfere with the normal flow of the inner outdoor air, thereby increasing the turbulent state of the air and improving the heat exchange effect.

[0024] At the same time, the up and down floating action of the heat exchange plate 17 will cause the squeezed spring 22 below to bounce up and down. At this time, the liquid on the heat exchange plate 17 will fall rapidly under the floating action and be hit by the bouncing spring 22 below, so that scattered water droplets are formed around the spring 22, increasing the contact area between the external air introduced from the surrounding and the water, and improving the efficiency of the external air obtaining moisture.

[0025] The side walls of the hollow rubber 16 and the heat exchange plate 17 close to the inner wall of the exchange chamber 2 are in contact with the inner wall of the exchange chamber 2, so that the heat exchange plate 17 can only reciprocate up and down when moving, and the hollow rubber 16 is pulled and stretched downward when the heat exchange plate 17 moves downward. When the heat exchange plate 17 moves upward, the hollow rubber 16 shrinks and recovers, so that most of the indoor air can only pass through the heat exchange air duct 19.
