Description

Technical Field

[0001] The utility model relates to the technical field of in-vehicle dehumidification, in particular to an intelligent humidity control device for the interior of a recreational vehicle. Background Technique

[0002] When a recreational vehicle stays outdoors, due to the relatively high humidity of the outdoor air, it may accelerate the corrosion rate of the interior decoration and equipment of the recreational vehicle. Therefore, a special dehumidification device is provided in modern recreational vehicles to keep the interior humidity balanced. The dehumidification device generally sucks the humid air into the machine by a fan. In the heat exchanger, at this time, the water molecules in the air condense into water droplets, and the processed dry air is discharged outside the machine. In this way, the interior humidity is kept at an appropriate relative humidity through circulation. However, for the existing dehumidification device of a recreational vehicle, when the condensing pipe contacts the air for heat exchange, the contact area between the condensing pipe and the heat exchanger is relatively fixed, and the air entering and loaded can only contact the condensing pipe slowly and disorderly in a free state, which may lead to a relatively low heat exchange efficiency of the condensing pipe. Based on this, an intelligent humidity control device for the interior of a recreational vehicle is proposed. Content of the Utility Model

[0003] To solve the technical problem of in-vehicle dehumidification, the utility model provides an intelligent humidity control device for the interior of a recreational vehicle.

[0004] The utility model is realized by adopting the following technical scheme: an intelligent humidity control device for the interior of a recreational vehicle, including a tank body. One side of the tank body is respectively communicated with a refrigerant inlet pipe and a refrigerant return pipe. The refrigerant inlet pipe and the refrigerant return pipe extend towards the interior of the tank body near the tank body. One ends of the refrigerant inlet pipe and the refrigerant return pipe located inside the tank body are jointly communicated with a condensing pipe. A air supply mechanism is arranged on one side of the tank body, a pressure balance mechanism is arranged above the tank body, and a condensed water drainage mechanism is arranged on the other side of the tank body.

[0005] As a further improvement of the above scheme, the air supply mechanism includes a mounting table fixedly connected to one side of the tank body. A fan unit is arranged on one side of the mounting table. A humidity sensor communication module fixedly connected to one side of the mounting table is arranged above the fan unit. A second culvert is opened inside the mounting table. The upper end of the second culvert is communicated with the ventilation duct at the rear side of the fan unit. A first culvert is opened inside the bottom of the tank body of the tank body. The first culvert is communicated with the second culvert. An air filtering mechanism is arranged at one end of the first culvert.

[0006] As a further improvement of the above scheme, the air filtering mechanism includes a boss fixedly connected to the upper side of the bottom of the tank body. A notch is opened at the central position of the boss. The notch is communicated with one end of the first culvert close to the center of the bottom of the tank body. A filter element is installed inside the notch.

[0007] As a further improvement of the above solution, the air pressure balance mechanism includes a cover plate threadedly sleeved on the upper side of the tank body. A spring is fixedly connected to the lower side of the cover plate, and the lower end of the spring is fixedly connected to a pressure stabilizing piston that is slidably connected to the inside of the tank body. The pressure stabilizing piston is located above the condenser tube.

[0008] As a further improvement of the above solution, the condensed water drainage mechanism includes a water gathering groove opened on the convex platform. A baffle is arranged on one side of the water gathering groove close to the tank body, and the baffle is fixedly connected to the tank body. A water through groove is opened at the bottom of the water gathering groove, and a third culvert tube that slopes downward is opened inside the baffle. The lower end of the third culvert tube communicates with the water through groove, and the upper end of the third culvert tube communicates with a drain pipe.

[0009] As a further improvement of the above solution, one side of the tank body is communicated with an exhaust pipe, and the installation height of the exhaust pipe is the same as the height inside the tank where the pressure stabilizing piston is located.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. By arranging a spiral conical condenser tube inside the tank body of the present utility model, when low-temperature liquid refrigerant is introduced into the condenser tube, and humid air in the recreational vehicle enters the tank body from the first culvert tube, since the heat exchange area of the threaded tube at the upper end of the condenser tube is larger than that at the lower end and absorbs more heat, the temperature of the air above inside the tank body is lower, while the temperature of the air below is higher, generating a temperature difference. According to the principle of thermal expansion and contraction, the air below flows upward, and the air with a lower temperature above flows downward, forming strong convection. In this way, the efficiency of the humid air coming into full contact with the surface of the condenser tube can be expanded, the heat exchange capacity can be improved, and the refrigeration effect of the device can be made more rapid;

[0012] 2. By arranging an air pressure balance mechanism above the inside of the tank body of the present utility model, when the pressure inside the tank body exceeds a certain intensity, the pressure stabilizing piston can be pushed to move upward, so that the dehumidified air is discharged from the exhaust pipe. In this way, not only can the air pressure inside the tank be always maintained within a safe range, but also the gas inside the tank can be fully dehumidified. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features to form a new embodiment.

[0022] Embodiment:

[0023] Please refer to Figures 1-6 , a humidity intelligent control device inside a recreational vehicle in this embodiment includes a tank body 1. One side of the tank body 1 is respectively communicated with a refrigerant inlet pipe 6 and a refrigerant return pipe 7. Through the air-conditioning refrigeration cycle, the compressor repeatedly experiences the cycle of compression, condensation, expansion, and evaporation of the limited refrigerant, so as to absorb heat and vaporize at the condensing pipe 12 to achieve the purpose of refrigeration and cooling. The refrigerant inlet pipe 6 and the refrigerant return pipe 7 extend towards the inside of the tank body 1 near the tank body 1. Among them, the refrigerant enters from the refrigerant inlet pipe 6 and returns from the refrigerant return pipe 7. One ends of the refrigerant inlet pipe 6 and the refrigerant return pipe 7 located inside the tank body 1 are jointly communicated with a condensing pipe 12. The condensing pipe 12 is in a spiral conical shape. A air supply mechanism is arranged on one side of the tank body 1, a pressure balance mechanism is arranged above the tank body 1, and a condensed water drainage mechanism is arranged on the other side of the tank body 1.

[0024] Through the above technical solution, low-temperature refrigerant can be provided in the condensing pipe 12 to take away heat from the tank.

[0025] Please refer to Figure 4As shown in the figure, the air supply mechanism includes a mounting table 4 fixedly connected to one side of the tank body 1. A blower unit 8 is arranged on one side of the mounting table 4. The blower unit 8 includes a motor and a communication module, which receives the signal from the communication module 9 of the humidity sensor. Above the blower unit 8, there is a communication module 9 of the humidity sensor fixedly connected to one side of the mounting table 4. When the air humidity outside exceeds a certain threshold, the blower is started to blow in air. A second culvert 16 is opened inside the mounting table 4. The upper end of the second culvert 16 is communicated with the ventilation duct at the rear side of the blower unit 8. A first culvert 15 is opened inside the bottom of the tank body 1. The first culvert 15 is communicated with the second culvert 16. An air filtering mechanism is arranged at one end of the first culvert 15.

[0026] Please refer to Figure 4 As shown in the figure, the air filtering mechanism includes a boss 13 fixedly connected to the upper side of the bottom of the tank body 1. The middle of the boss 13 is high and the edge is low. A notch is opened at the center position of the boss 13. The notch is communicated with one end of the first culvert 15 close to the center of the bottom of the tank body 1. A filter element 14 is installed inside the notch. The air inside the recreational vehicle can be filtered and refreshed through the filter element 14. There are various types of materials for the filter element 14 currently, and corresponding selections can be made according to actual needs.

[0027] Please refer to Figure 4 As shown in the figure, the air pressure balancing mechanism includes a cover plate 2 threadedly sleeved on the upper side of the tank body 1. By adjusting the height of the cover plate 2, the pressure of the gas contained in the tank body 1 can be indirectly adjusted. A spring 11 is fixedly connected to the lower side of the cover plate 2. The lower end of the spring 11 is fixedly connected to a pressure stabilizing piston 10 that is slidably connected to the inside of the tank body 1. The pressure stabilizing piston 10 is located above the condenser tube 12. The air pressure inside the tank body 1 can be indirectly controlled through the spring 11, playing a protective role.

[0028] Please refer to Figure 5 As shown in the figure, the condensate drainage mechanism includes a water collecting groove 18 opened on the boss 13. A baffle is arranged on the side of the water collecting groove 18 close to the tank body 1. The baffle is fixedly connected to the tank body 1. A water passing groove is opened at the bottom of the water collecting groove 18. A downwardly inclined third culvert 17 is opened inside the baffle. The lower end of the third culvert 17 is communicated with the water passing groove. The upper end of the third culvert 17 is communicated with a drain pipe 5. The U-shaped communicating vessel formed can seal the gas inside the tank to prevent gas leakage.

[0029] Please refer to Figure 5 As shown in the figure, one side of the tank body 1 is communicated with an exhaust pipe 3. The installation height of the exhaust pipe 3 is the same as the height inside the tank where the pressure stabilizing piston 10 is located.

[0030] In the embodiment of the present application, the implementation principle of an intelligent humidity control device inside a recreational vehicle is as follows: when the humidity sensor communication module 9 detects that the air humidity inside the recreational vehicle exceeds a certain threshold, it sends a signal to start the fan unit 8, and the air inside the recreational vehicle is introduced into the tank body 1 through the second culvert 16 and the first culvert 15, and is filtered and cleaned by the filter element 14. Then, the compressor is started, and the compressed and cooled refrigerant is connected through the refrigerant inlet pipe 6. Then, the refrigerant passes through the condenser pipe 12 and makes full contact with the introduced air inside the recreational vehicle. The air condenses into water when it meets the cold, and the water drops onto the upper surface of the boss 13, and then gathers and flows into the water collecting groove 18. When the condensed water flowing in exceeds a certain height, according to the principle of communicating vessels, it can be discharged from the drain pipe 5. When the air pressure injected into the tank body 1 is greater than the gravity of the pressure stabilizing piston 10 and the spring 11, at this time, the air pressure pushes the pressure stabilizing piston 10 to move upward, leaking out the exhaust pipe 3, and the air that has been fully dehumidified is discharged from the exhaust pipe 3 and re-enters the inside of the recreational vehicle.

[0031] The above-mentioned implementation manner is only the preferred implementation manner of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention shall fall within the scope of protection required by the present invention.
