Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning refrigeration, in particular to a valve box for a refrigeration device. Background Art

[0002] The refrigeration valve box can be applied to air-conditioning equipment. Referring to the Chinese invention patent with the application number 2013103139670, it discloses a valve box for an air conditioner, which consists of a valve box body and an electric control box. The valve box body includes a box body structure, and a water receiving tray is arranged inside the box body structure. The water receiving tray is connected with a drain pipe, and the condensed water generated by the system components inside the box body structure can be discharged through the water receiving tray. The electric control components are arranged inside the electric control box; during actual use, a cooling fan is configured inside the electric control box to dissipate heat from the inside of the box, and the condensed water generated inside the box body structure is directly discharged. Since when the air conditioner is refrigerating, the condensed water collected in the water receiving tray is at a relatively low temperature and has a good cooling effect, and it is directly discharged, the electric control box needs to consume electric energy for heat dissipation and cooling, and the condensed water is not reasonably utilized. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and provide a valve box for a refrigeration device that can utilize the condensed water generated by itself to dissipate heat from its own electric control box, achieving the purpose of saving energy consumption.

[0004] To achieve the above purpose, the technical solution of the utility model is: a valve box for a refrigeration device, including a valve box structure and an electric control box. The valve box structure is provided with a drain pipe, the electric control box is arranged below the valve box structure, and a heat exchange tube is arranged inside the valve box structure. The heat exchange tube is communicated with the drain pipe.

[0005] Specifically, in this application, a heat exchange tube is arranged inside the electric control box. By connecting the heat exchange tube and the drain pipe, when there is condensed water flowing out of the drain pipe inside the valve box structure, the condensed water can pass through the heat exchange tube and then flow out of the electric control box from the other end of the heat exchange tube. The heat exchange tube can exchange heat between the condensed water and the inside of the electric control box, cool the inside of the electric control box, thereby effectively utilizing the condensed water for cooling, reducing the power consumption of the exhaust fan of the electric control box, and achieving the purpose of energy conservation.

[0006] Furthermore, a water collecting box communicated with the drain pipe is arranged on the electric control box. The water collecting box is provided with a first water outlet and a second water outlet. The first water outlet is located at the bottom of the water collecting box, and the second water outlet is arranged above the first water outlet and lower than the drain pipe. The heat exchange tube of the water collecting box includes a first tube and a second tube. The flow area of the first tube is smaller than that of the second tube. The first tube is communicated with the first water outlet, and the second tube is communicated with the second water outlet.

[0007] Specifically, by setting up a water collecting box, the condensed water can be collected and then flows into the first pipe through the first water outlet. Heat exchange is carried out through the first pipe. When too much condensed water is generated and the first pipe cannot drain it in time, the liquid level rises. By setting up the second water outlet and the second pipe, the condensed water can be drained from the second pipe when it is collected too much. The condensed water can exchange heat with the inside of the electronic control box through the second pipe, ensuring that the liquid level in the water collecting box is lower than the drain pipe, so as to ensure that the water in the valve box structure can be drained in time.

[0008] Further, the flow area of the first pipe is smaller than that of the drain pipe, and the flow area of the second pipe is larger than that of the drain pipe.

[0009] Specifically, setting the flow area of the first pipe smaller than that of the drain pipe can reduce the flow rate of the condensed water flowing out of the first pipe, avoid the problem of water condensation on the outer wall of the first pipe due to too fast flow rate of the condensed water, improve safety, and enable the condensed water to exchange heat fully. Setting the flow area of the second pipe larger than that of the drain pipe ensures that when the liquid level reaches the second water outlet, the condensed water drained from the drain pipe can be drained in time, ensuring that the liquid level in the water collecting box is lower than the drain pipe, so as to ensure that the water in the valve box structure can be drained in time.

[0010] Further, a plurality of heat exchange plates are downwardly extended on the lower side wall of the valve box structure, and at least part of the plurality of heat exchange plates can extend into the interior of the electronic control box.

[0011] Specifically, by setting up the heat exchange plates, the low temperature of the lower side wall of the valve box structure can be exchanged with the inside of the electronic control box through the heat exchange plates, making full use of the low temperature of the condensed water and further reducing the energy consumption of the cooling fan.

[0012] Further, one side of the electronic control box close to the valve box structure is open, and the electronic control box is detachably connected to the valve box structure.

[0013] Specifically, through this setting method, the electronic control box can be set on the lower side wall of the valve box structure. At this time, the heat exchange plates can exchange heat with the inside of the electronic control box, and the structure is simple.

[0014] Further, a cooling fan is also configured in the electronic control box.

[0015] Specifically, by setting up the cooling fan, it can cooperate with the condensed water to dissipate heat. The flowing air flow is more likely to enable heat exchange between the inside of the electronic control box and the heat exchange pipe, improve the heat exchange efficiency, ensure the heat dissipation effect, and can also carry out heat exchange through the cooling fan when there is no condensed water generated.

[0016] Further, it also includes a control device. A solenoid valve is arranged between the first water outlet and the first pipe. A temperature sensor is arranged in the electronic control box. The control device is connected to the solenoid valve, the cooling fan and the temperature sensor.

[0017] Specifically, by setting a temperature sensor to detect the temperature inside the electronic control box, the opening and closing of the solenoid valve and the operation of the cooling fan can be controlled according to the temperature inside the electronic control box, so that the condensed water can be fully utilized and lower energy consumption can be achieved.

[0018] A valve box for a refrigeration device disclosed by the present utility model has the following beneficial effects compared with the prior art: by arranging a heat exchange tube inside the electronic control box and connecting the heat exchange tube with a drain pipe, when condensed water flows out of the drain pipe inside the valve box structure, the condensed water can pass through the heat exchange tube and then flow out of the electronic control box from the other end of the heat exchange tube. The heat exchange tube can exchange heat between the condensed water and the inside of the electronic control box to cool down the inside of the electronic control box, so that the condensed water can be effectively utilized for cooling, reducing the power consumption of the exhaust fan inside the electronic control box and achieving the purpose of energy saving. A valve box for a refrigeration device includes a valve box structure and an electronic control box. The valve box structure is provided with a drain pipe. The electronic control box is arranged below the valve box structure. A heat exchange tube is arranged inside the valve box structure. The heat exchange tube includes a connection with the drain pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0025] Please refer to Figures 1-4, this application provides a valve box for a refrigeration device, including a valve box structure 1 and an electric control box 2. The valve box structure 1 is provided with a drain pipe 10. The electric control box 2 is arranged below the valve box structure. A heat exchange pipe 21 is arranged in the valve box structure, and the heat exchange pipe 21 is communicated with the drain pipe 10.

[0026] Specifically, it should be noted that the specific structures and functions of the valve box structure 1 and the electric control box 2 in this application are the same as those in a valve box for an air conditioner in the background technology. Since there are system components in the valve box structure and refrigerant will flow in the pipelines included in the system components, condensed water will be formed by condensation on the pipeline surface. In this application, a water receiving tray (not shown in the figure) is also provided. The drain pipe 10 is connected to the water receiving tray to discharge the condensed water in the water receiving tray. Refer to Figure 3 , a through hole 16 through which the drain pipe extends is provided on the side wall of the valve box structure. In this application, a heat exchange pipe 21 is arranged in the electric control box 2. By connecting the heat exchange pipe 21 and the drain pipe 10, when condensed water flows out of the drain pipe in the valve box structure 1, the condensed water can pass through the heat exchange pipe 21 and then flow out of the electric control box from the other end of the heat exchange pipe. The heat exchange pipe can exchange heat between the condensed water and the inside of the electric control box to cool the inside of the electric control box, so as to effectively utilize the condensed water for cooling, reduce the power consumption of the exhaust fan in the electric control box, and achieve the purpose of energy saving.

[0027] Furthermore, as a preferred implementation manner, refer to Figure 2 , Figure 4 , a water collecting box 3 communicated with the drain pipe 10 is arranged on the electric control box 2. The water collecting box 3 is provided with a first water outlet 31 and a second water outlet 32. The first water outlet is located at the bottom of the water collecting box. The second water outlet is arranged above the first water outlet and lower than the drain pipe. The heat exchange pipe 21 of the water collecting box includes a first pipe 213 and a second pipe 214. The flow area of the first pipe is smaller than that of the second pipe. The first pipe is communicated with the first water outlet, and the second pipe is communicated with the second water outlet.

[0028] Specifically, when the humidity in the air is high, a large amount of condensed water will be generated inside the valve box structure. When a large amount of condensed water continuously drains from the electric control box, the temperature of the drained condensed water is still relatively low, which will cause condensed water to form on the surface of the first pipe 213, which is not beneficial to the electrical equipment inside the electric control box. To solve this problem, the present application provides a water collection box 3 that can collect the condensed water, and then the condensed water flows into the first pipe 213 through the first water outlet, and heat exchange is carried out through the first pipe 213. The cross-sectional area of the first pipe is set to be relatively small, and the flow rate of the condensed water flowing in the first pipe 213 is relatively small. Therefore, after heat exchange with the inside of the electric control box, the temperature of the condensate pipe can rise to 20 to 30 degrees Celsius, and the surface temperature of the first pipe will not be too low, reducing the probability of condensed water forming on the surface of the first pipe, improving safety, and also being able to make full use of the condensed water. When too much condensed water is generated and the first pipe cannot drain it in time, the liquid level rises. By setting the second water outlet 32 and the second pipe 214, the condensed water can be drained from the second pipe when too much condensed water is collected, and the condensed water can exchange heat with the inside of the electric control box through the second pipe, ensuring that the liquid level in the water collection box is lower than the drain pipe 10, thereby ensuring that the water in the valve box structure can be drained in time.

[0029] Further, as a preferred embodiment, a heat insulation layer (not shown in the figure) is provided on the inner or outer side wall of the water collection box. When the heat insulation layer is provided on the outer side wall of the water collection box, it can be made of materials such as heat-insulating cotton, so as to reduce the heat exchange between the inside and outside of the water collection box and ensure the low temperature of the condensed water.

[0030] Further, as a specific embodiment, the flow area of the first pipe 213 is smaller than the flow area of the drain pipe 10, and the flow area of the second pipe is larger than the flow area of the drain pipe.

[0031] Specifically, setting the flow area of the first pipe to be smaller than the flow area of the drain pipe can reduce the flow rate of the condensed water flowing out of the first pipe, avoid the problem of condensed water forming on the outer wall of the first pipe due to too fast a flow rate of the condensed water, improve safety, and enable the condensed water to exchange heat fully. Setting the flow area of the second pipe to be larger than the flow area of the drain pipe ensures that when the liquid level reaches the second water outlet 32, the condensed water drained from the drain pipe can be discharged in time, ensuring that the liquid level in the water collection box is lower than the drain pipe 10, thereby ensuring that the water in the valve box structure can be drained in time.

[0032] Further, referring to Figure 3 , as a specific embodiment, a plurality of heat exchange plates 13 are downwardly extended on the lower side wall of the valve box structure 1, and at least part of the plurality of heat exchange plates 13 can extend into the interior of the electric control box 2.

[0033] Specifically, by providing the heat exchange plates 13, the low temperature of the lower side wall of the valve box structure can be exchanged with the inside of the electric control box through the heat exchange plates 13, making full use of the low temperature of the condensed water and further reducing the energy consumption of the cooling fan.

[0034] Further, as a specific implementation manner, one side of the electric control box 2 close to the valve box structure 1 is open, and the electric control box 2 is detachably connected to the valve box structure 1.

[0035] Specifically, in this setting mode, the electric control box can be arranged on the lower side wall of the valve box structure. At this time, the heat exchange plate can exchange heat with the inside of the electric control box, and the structure is simple. The electric control box can be detachably fixed to the valve box structure by screws.

[0036] Further, a cooling fan 4 is also arranged in the electric control box 2.

[0037] Specifically, by arranging the cooling fan 4, it can cooperate with the condensed water to dissipate heat. The flowing air flow is more likely to exchange heat between the inside of the electric control box and the heat exchange tube 21, improving the heat exchange efficiency and ensuring the heat dissipation effect. It can also exchange heat through the cooling fan when there is no condensed water generated.

[0038] Further, a control device 5 is also included. A solenoid valve 33 is arranged between the first water outlet 31 and the first pipe 213. A temperature sensor 6 is arranged in the electric control box 2. The control device 5 is connected to the solenoid valve, the cooling fan 4 and the temperature sensor 6.

[0039] Specifically, by arranging the temperature sensor to detect the temperature inside the electric control box, it can control the opening and closing of the solenoid valve 33 and the operation of the cooling fan according to the temperature inside the electric control box, so as to make full use of the condensed water and achieve lower energy consumption.

[0040] Specifically, the heat dissipation working steps of the valve box for the electric control box in this application are as follows:

[0041] Step 1: The valve box starts to work.

[0042] Step 2: Detect the temperature inside the electric control box through the temperature sensor. When the temperature inside the valve box rises above the appropriate temperature, control the solenoid valve to open. At this time, the condensed water inside the water collecting box 3 can flow through the first pipe to exchange heat with the inside of the valve box and exchange heat with the inside of the valve box.

[0043] If the temperature inside the electric control box no longer rises, the cooling fan does not work;

[0044] If the temperature inside the electric control box continues to rise, the cooling fan works to participate in heat dissipation to ensure that the temperature inside the electric control box is maintained within the appropriate temperature range;

[0045] If the temperature inside the electric control box drops below the appropriate working range, control the solenoid valve to close.

[0046] Step 3: Continuously detect the temperature inside the electronic control box through the temperature sensor. If the temperature rises above the appropriate working range and the solenoid valve is in the closed state, control the solenoid valve to open; if the solenoid valve is in the open state, obtain the working state of the exhaust fan. If the exhaust fan is in the working state, control the exhaust fan to increase its working power. If the exhaust fan is in the non-working state, control the exhaust fan to start working.

[0047] Step 4: Continuously detect the temperature inside the electronic control box through the temperature sensor. If the temperature inside the electronic control box continues to rise, confirm the working state of the cooling fan. If the exhaust fan is in the working state, control the exhaust fan to increase its working power. If the exhaust fan is in the non-working state, control the exhaust fan to start working; if the temperature drops below the appropriate temperature range, confirm the working state of the solenoid valve. When the solenoid valve is in the open state, obtain the working state of the exhaust fan. When the exhaust fan is working, reduce the working power of the exhaust fan. When the exhaust fan is in the closed state, control the solenoid valve to close.

[0048] Step 5: Repeat Step 3 and Step 4 to ensure that the electromagnetic valve is within the appropriate temperature range.

[0049] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or variations derived therefrom are still within the protection scope of the present invention.
