Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning water tanks, in particular to an air-conditioning humidifying water tank. Background Art

[0002] Controlled atmosphere humidification water tanks are widely used in various types of controlled atmosphere warehouses, such as food fresh-keeping warehouses, fruit and vegetable storage warehouses, refrigerated controlled atmosphere fresh-keeping containers, etc. By maintaining a suitable humidity environment in the warehouse, it helps to extend the shelf life of food and maintain the color and texture of food.

[0003] The conventional working principle of a controlled atmosphere humidification water tank is to inject water into the water tank. When it reaches a certain water level, the transducer (such as an ultrasonic generator) at the bottom of the water tank converts electrical energy into mechanical energy and emits high-frequency oscillations into the water, causing the water surface to produce ultrafine particles under the action of the cavitation effect. Subsequently, the axial flow fan starts and sends the water mist particles out through the conveying pipeline to exchange heat and moisture with the flowing air to achieve the effect of isenthalpic humidification of the air. During the process, the water level has an important influence on the function of the transducer. In order to maintain the good performance of the transducer, the optimal water level of the water tank generally needs to be maintained at about 2-3 cm higher than the transducer.

[0004] Existing controlled atmosphere humidification tanks are generally divided into fixed and floating types. In fixed-type controlled atmosphere humidification tanks, the transducer is fixed to the bottom of the tank. As water mist is generated, the water volume decreases and the water level drops. Therefore, water needs to be added frequently to maintain the optimal water level. Frequent water addition will reduce the service life of the water pump and increase energy consumption. At the same time, additional control devices are required to control the water addition to achieve fast and accurate water addition. The control requirements are high and the device is complex. In floating-type controlled atmosphere humidification tanks, a float is installed inside the tank to control the water level. The float automatically floats up and down according to the water level. When the water level is lower than the set value, the float drops with the water level, triggering the water supply pipeline to open and add water to the tank. When the water level reaches the set value, the float rises with the water level, triggering the water supply pipeline to close and stop adding water. In this method, because conventional floats have no fixed device, the floats swing greatly in the water. Coupled with too many other uncontrollable factors, water addition is difficult to control and the humidification effect is poor. Utility Model Content

[0005] The utility model is intended to provide an atmosphere-controlled humidifying water tank, which is used to solve the technical problems of frequent water addition in existing fixed atmosphere-controlled humidifying water tanks and large swing of the float in floating atmosphere-controlled humidifying water tanks that affects the humidification effect.

[0006] The basic solution provided by the utility model is: an air-conditioning humidifying water tank, comprising a box body and a humidifying device movably installed inside the box body;

[0007] The upper part of the box body is provided with a water inlet, an air inlet and an air outlet; two limiting grooves extending in the height direction of the box body are oppositely provided on the two inner walls of the box body;

[0008] The humidifying device includes a transducer and two floats; the transducer is installed between the two floats; the top surfaces of the two floats are level; the top surface of the transducer is located below the top surfaces of the two floats, and there is a height difference between the top surfaces of the two floats; the two floats are used to drive the transducer to suspend in the water when the water level in the box changes within a certain range, and drive the transducer to float up and down simultaneously with the water level change, and the top surfaces of the two floats are level with the water surface, so as to achieve a constant height difference between the top surface of the transducer and the water surface; the height difference is any value within the optimal water level range when the transducer is working;

[0009] A limiting piece adapted to the limiting groove is provided at one end of the float away from the transducer; the two floats and the transducer are limited between the two limiting grooves by the two limiting pieces, so that the two floats drive the transducer to float up and down along the limiting groove.

[0010] The working principle and advantages of the utility model are as follows: the two floats and the transducer are installed together, and when there is no water, they are located at the bottom of the box at the same time, and the floats are limited in the limiting groove by the limiting piece. After water is injected into the box to a certain height through the water inlet, the two floats drive the transducer to float in the water. When the water level in the box changes within a certain range, the two floats drive the transducer to float up and down at the same time, and the top surfaces of the two floats are level with the water surface; on the basis that the top surfaces of the two floats are level with the water surface, since the top surface of the transducer and the top surface of the float have a specially set height difference, the top surface of the transducer and the water surface always maintain this height difference, thereby maintaining the optimal water level for the formation of water mist of the transducer; in this process, through the setting of the limiting piece and the limiting groove, the two floats drive the transducer to float up and down along the limiting groove in the height direction of the box. Based on the size and shape of the box, the size and shape of the float are effectively designed, the float is filled with water in advance, and then the float water inlet is closed, which can achieve the same buoyancy and gravity of the float, making the top surface of the float level with the water surface.

[0011] Compared with the existing technology, this solution deeply explores the relationship between the top surface of the float, the water surface and the top surface of the transducer during the water level change and water mist formation, and optimizes the water tank structure based on this, completely changing the working mode of the float and taking into account the advantages of the existing fixed and floating type controlled atmosphere humidification tanks. This solution abandons the conventional thinking of using floats to detect water levels. Instead, it cleverly utilizes the basic function of floats that floats up and down with changes in water levels, and develops a method of fixing the float to the transducer. Based on the specially selected float size and the specially set height difference between the float and the transducer, water is added only when the water storage is at a water shortage level. The entire process does not require frequent water addition. When the water level changes within a certain range, the buoyancy of the float itself is used to drive the position of the transducer to change, and the change in the position of the transducer is used to adapt to the change in the water level. In addition, due to the special installation method of the transducer and the float, the transducer is always kept at the optimal water level required for optimal performance. The limiting structure is used to prevent the float from swinging, keep the transducer position stable and always at the optimal water level, and continuously maintain the optimal humidification effect. The adjustment method in the process is simplified, the adjustment is fast and accurate, and no complex control system is required. No additional control equipment is required. The structure is simple, maintenance is convenient, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is a further detailed description through specific implementation methods:

[0016] The marks in the drawings of the specification include: box body 1, air inlet 2, air outlet 3, water inlet 4, overflow port 5, sewage outlet 6, limit groove 1 7, limit groove 2 8, ultrasonic generator 9, limit member 1 10, limit member 2 11, float 1 12, float 2 13, float water inlet 1 14, float water inlet 2 15, limit switch 1 16, limit switch 2 17.

[0017] The embodiment is basically as shown in the attached Figure 1 、 Figure 2 and Figure 3 Shown: A gas-controlled humidifying water tank, comprising a tank body and a humidifying device movably installed inside the tank body.

[0018] The upper part of the box body is provided with a water inlet, an air inlet and an air outlet. Specifically, when the box body is a square structure, the box body includes two opposite side walls, and the two opposite side walls can be selected as short side walls; the water inlet 4 is provided at the upper part of any side wall, close to the top of the box body, for effectively injecting water into the box body. The water can be purified water, etc. The water inlet 4 can be connected to an external water pump. The air inlet 2 and the air outlet 3 are relatively provided at the upper part of the two side walls, close to the top of the box body, for effectively circulating the mist out of the humidification equipment outside the box body for humidification. The air outlet 3 and the air inlet 2 can be externally connected to a duct fan to accelerate the rapid circulation of the mist. In this embodiment, the air inlet 2 is provided next to the water inlet 4, and the bottoms of the two are parallel, which is convenient for installation and layout of multiple external devices.

[0019] Two limiting grooves extending along the height direction of the box are arranged on the two inner walls of the box, and the limiting grooves are located on the vertical center line of the corresponding inner wall, so that the limiting grooves are located in the middle position inside the box, which is convenient for the central installation of the subsequent humidification device. Figure 3 As shown, the two limit grooves are limit groove 1 7 and limit groove 2 8 respectively. The limit grooves are formed by two L-shaped steels arranged vertically at intervals. The distance between the two L-shaped steels is the first interval, and the length direction of the L-shaped steel is the height direction of the box body. The arrangement shown in the figure has a simple structure, is easy to maintain, and has low cost.

[0020] The two inner walls of the box are also provided with a limit switch 16 and a limit switch 2 17. The two limit switches can be provided on the same inner wall or on different inner walls, as long as they can achieve the corresponding functions. In this embodiment, the limit switch 16 and the limit switch 2 17 are installed on the inner wall where the air inlet 2 is located, along the height direction of the box ( Figure 2 The installation height of the limit switch 16 is greater than the installation height of the limit switch 2 17, and is less than the installation height of the air inlet 2. The height difference between the limit switch 16 and the air inlet 2 is 5-10mm. The limit switch 16 provides the controller with a signal that the water in the box is in place, so as to avoid the inability to observe the amount of water added. When there is too much water, water will enter the air inlet and outlet, affecting the water mist discharge effect. In addition, the limit slot extends from the bottom of the box to the top of the box to a first height, and the first height is not less than the installation height of the limit switch 16. Regarding height, in this embodiment, the first height is consistent with the installation height of limit switch 16, which can also be understood as the top of the L-shaped steel being level with the bottom of limit switch 16. This ensures that the water storage capacity of the box is appropriate, the box is efficiently utilized, and the humidifier is effectively limited by the limit groove throughout the entire process of water level fluctuations. The installation height of limit switch 2 17 is higher than the height of the top surface of the float when there is no water, with a height difference of 5-10mm. Limit switch 2 17 provides the controller with a signal indicating water shortage in the box, preventing damage to the transducer caused by water shortage. The limit switches 1 and 2 do not interfere with the humidifier, ensuring smooth movement of the humidifier.

[0021] The humidifying device includes a transducer and two floats; the two floats are float one 12 and float two 13.

[0022] The transducer may be an ultrasonic generator 9, which is used to convert the water in the box into water mist.

[0023] The transducer is installed between two floats so that the two floats drive the transducer to float up and down; the top surfaces of the two floats are level; the top surface of the transducer is located below the top surfaces of the two floats, and there is a height difference between the top surfaces; the height difference is any value within the optimal water level range when the transducer is working.

[0024] Specifically, one side of the two floats is provided with a slot. In this embodiment, Figure 1 As shown, the slot is located in the lower middle position of one side of the float, and the height difference between the top surface of the slot and the top surface of the float is set to any value within the optimal water level range when the transducer is working. The optimal water level is about 2 to 3 cm, and can be set to 2.5 cm; the two ends of the transducer are respectively inserted into the slots of the corresponding floats for limit installation, and the top surfaces at both ends of the transducer contact the top surface of the slot. Thus, the height difference between the top surface of the transducer and the top surfaces of the two floats is the height difference between the top surface of the slot and the top surface of the float, and the transducer and the float can be fixed with bolts, that is, the height difference between the top surface of the transducer and the top surfaces of the two floats is fixed to any value within the optimal water level range when the transducer is working; the bottom of the transducer is level with the bottom of the two floats, and the shapes of the three are kept adapted, which not only meets the requirement of suspension, but also avoids the existence of high and low shapes at the bottom, resulting in too high water shortage limit and ineffective utilization of the water storage in the box.

[0025] The top of the float is provided with a float water injection port, which are a float water injection port 14 corresponding to float 12 and a float water injection port 2 15 corresponding to float 2 13. Water is injected into the float in advance through the float water injection port, and then the float water injection port is closed. Combined with the special calculation of the size and shape of the float, the buoyancy and gravity of the float can be made equal, so that the liquid surface and the top of the float are level; this water injection method can also flexibly adjust the amount of water injected into the float, adapt to changes in the size of the box, and improve the versatility of the device.

[0026] The end of the float away from the transducer is provided with a limiting piece adapted to the limiting groove, and the two floats and the transducer are limited between the two limiting grooves by the two limiting pieces, so that the two floats drive the transducer to float up and down along the limiting groove.

[0027] Specifically, the limiting member 10 of float 12 corresponds to the limiting groove 17, and the limiting member 2 11 of float 2 13 corresponds to the limiting groove 2 8; the limiting member 10 and the limiting member 2 11 limit float 12 and float 2 13 in the limiting groove 17 and the limiting groove 2 8 respectively, to ensure that the float only floats up and down along the limiting groove, to avoid the float from swinging too much laterally in the water, which affects the humidification effect. In this embodiment, the limiting member is formed by two square tubes vertically side by side, and is symmetrically installed on one side of the float. The width of the two square tubes side by side is the second interval, and the first interval of the two L-shaped steels is slightly wider than the second interval of the two square tubes, so that the square tubes are close to the L-shaped steel and can slide along the L-shaped steel. Through simple components, effective limiting is achieved to ensure that the movement direction is only up and down, and there is no displacement in other directions such as left, right, front and back, to avoid instability in the movement direction of the float.

[0028] Specifically, when in use, the float is filled with the required amount of water in advance, and then the float water inlet is closed; the ultrasonic generator and the two floats are fixed together in the above manner, and the floats are limited in the corresponding limit grooves by limiters; when there is no water, the ultrasonic generator and the two floats are located at the bottom of the box at the same time, and water is started to be poured into the box through the water inlet. After the water is filled to a certain height, the two floats drive the ultrasonic generator to start floating in the water. Since the buoyancy and gravity of the floats are the same, the water surface is level with the top surface of the floats. As the water injection continues to increase, the two floats drive the ultrasonic generator to move upward along the limit groove, which is not displaced by water surface fluctuations, and the top surface of the float is always level with the water surface. Since the top surface of the ultrasonic generator and the top surfaces of the two floats are constantly at a height difference, the distance between the top surface of the ultrasonic generator and the water surface is constant during the water level change. Height difference, the height difference is any value within the optimal water level range when the ultrasonic generator is working, and the ultrasonic generator is always in the optimal working performance; stop water injection after the limit switch 1 outputs a water addition signal; the ultrasonic generator works, converting water into water mist, which is discharged from the outside of the box through the air inlet and outlet. As the spray evaporates, the water level in the box gradually drops, and the two floats drive the ultrasonic generator to move down along the limit slot. Similarly, the water surface is level with the top surface of the float. The ultrasonic generator also maintains the optimal working efficiency during the water level drop process until the water level drops to the limit switch 2, and the water shortage signal is provided through the limit switch 2, and water is added again to realize the above process; during this up and down floating process, the two floats and the ultrasonic generator always move along the limit slot through the limit parts to achieve limit and avoid the influence of water surface fluctuations.

[0029] The present embodiment provides a controlled atmosphere humidification water tank, which optimizes the water tank structure after deeply exploring the relationship between the top surface of the float, the water surface and the top surface of the transducer during the process of water level changes and water mist formation, completely changes the working mode of the float, and takes into account the advantages of existing fixed and floating controlled atmosphere humidification water tanks. This solution abandons the conventional thinking of using a float to detect water levels. Instead, it cleverly utilizes the basic function of the float to float up and down with changes in water level, and develops a way to fix the float to the transducer. Based on the specially selected float size and the specially set height difference between the float and the transducer, water is added only when the water storage in the box is at a water shortage level. The entire process does not require frequent water addition. When the water level changes within a certain range, the buoyancy of the float itself is used to drive the position of the transducer to change, and the change in the transducer position is used to adapt to the change in water level. In addition, due to the special installation method of the transducer and the float, the transducer is always kept at the optimal water level required for optimal performance. The limit structure is used to avoid the float from swinging, and the change in the transducer position is kept stable, which simplifies the adjustment method and makes the adjustment fast and accurate. It does not require a complex control system or the participation of additional control equipment. It has a simple structure, is easy to maintain, and has a low cost.

[0030] Example 2

[0031] What is different from the first embodiment is that an overflow port 5 is further provided on the upper part of the box body, which can be located on the side of the air outlet 3 and opposite to the water inlet 4. It is used to detect the actual water level when a limit switch fails. After the water is added, the water pump continues to add water, resulting in excessive water in the box body. The excess water can be discharged through the overflow port to ensure the normal use of the water tank.

[0032] A sewage outlet 6 is provided at the bottom of any side wall of the box body, which can be located on the side of the air outlet 3. Its main function is to drain the internal water or discharge the deposited impurities when the water tank is not used for a long time to avoid damage to the ultrasonic humidifier.
