[0002] With the rapid development of the automobile industry and the continuous improvement of people's quality of life, vehicle air conditioning systems have become an indispensable part of modern vehicles, especially for RVs that are often in different climatic conditions, the efficient operation and maintenance of air conditioning systems are particularly important. Traditional vehicle air conditioning systems are mainly composed of indoor and outdoor units, which are responsible for adjusting the temperature and humidity in the car to ensure the comfort of drivers and passengers.

[0003] However, in actual applications, vehicle air-conditioning systems face many challenges, especially the outdoor unit, which is directly exposed to the external environment and easily accumulates pollutants such as dust, dirt, and sand, which seriously affects the heat dissipation performance of the condenser, resulting in decreased efficiency of the air-conditioning system, increased energy consumption, and shortened lifespan.

[0015] Beneficial Effects

[0016] The cleanable air conditioning system provided by the utility model realizes the autonomous cleaning and maintenance of the air conditioning system, improves the energy efficiency ratio, and enhances the durability of the system. By collecting the condensed water generated by the indoor unit and storing it in the water storage tank, the originally wasted water resources are reused to clean the condenser, realizing the effective recycling of water resources. The integrated infusion pump and spraying device can automatically pressurize the water in the water storage tank and spray it onto the surface of the outdoor unit condenser, effectively removing the accumulated dust and dirt, reducing the need for manual cleaning, and improving the maintenance efficiency. The sprayed water mist can not only clean the condenser, but also assist in heat dissipation through the evaporation process, improve the overall cooling efficiency of the air conditioning system, especially in high temperature environments, it can significantly enhance the operating efficiency of the air conditioning. For different driving environments, such as dust, rain, snow, extreme temperatures, etc., the cleaning process can be started in time to ensure that the air conditioning can maintain efficient and stable operation under harsh conditions. Through the setting of the filter, impurities in the condensed water are effectively intercepted, preventing pipe blockage and equipment damage, and extending the service life of the air conditioning system. Combined with the electronic control unit and the temperature sensor, the start and stop of the spraying system can be intelligently controlled according to the actual temperature of the condenser, realizing on-demand cooling, and further optimizing energy consumption and cooling efficiency. The external unit components are integrated and installed on the bottom bracket of the vehicle, which is convenient for maintenance and protection. At the same time, the design of the fan improves the heat exchange efficiency, and the configuration of the filter reduces the impact of foreign impurities on the internal structure. The setting of the overflow valve avoids system failure caused by excessive water accumulation in the water tank, ensuring the stable operation and continuous cleaning ability of the system.

[0017] The cleanable air conditioning system used in the RV provided by the utility model collects the condensed water generated by the internal unit and recycles it, which not only effectively saves water resources, but also realizes automatic cleaning and efficient heat dissipation of the external unit, thereby improving the operating efficiency and durability of the air conditioner. The intelligent temperature control and water mist auxiliary cooling functions can be automatically adjusted according to the ambient temperature, which not only optimizes the refrigeration performance but also reduces energy consumption when necessary. The overall design integrates multiple advantages such as environmental protection, self-cleaning, and energy efficiency management, making the use of RVs more comfortable and economical.

[0023] The present invention is further illustrated by the following examples, which are intended to more clearly illustrate the technical solution of the present invention and should not be construed as a limitation.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, Embodiment 1 provides a cleanable air conditioner for use in a vehicle, comprising an indoor unit 1 installed in the vehicle and an outdoor unit 2 installed under the vehicle.

[0025] The cleanable air conditioner is also equipped with a water tank 31, to which a drainage pipe 32 is connected, and the drainage pipe 32 drains the condensed water generated by the operation of the indoor unit 1 into the water tank 31. The water tank 31 is used to collect the condensed water generated by the indoor unit 1 during operation, rationally utilize the water resources that were originally discarded, and provide a water source for subsequent condenser cleaning. The drainage pipe 32 serves as a bridge connecting the indoor unit 1 and the water tank 31 to ensure that the condensed water can be smoothly transferred from the indoor unit 1 to the water tank 31. A spray pipe 34 is also provided in the outdoor unit 2, and an infusion pump 33 is connected between the spray pipe 34 and the water tank 31. The water in the water tank 31 is pressurized by the infusion pump 33 and sprayed from the spray pipe 34 onto the outdoor unit 2, helping to remove dirt on the surface of the condenser and achieving effective cleaning. At the same time, the water mist can also help cooling and improve the operating efficiency of the air conditioner.

[0026] The vehicle may encounter various complex environments during driving, including dusty roads, rainy and snowy weather, high temperature or extremely cold climate, etc. These environmental factors easily cause the outdoor unit 2 to accumulate dust, mud and other pollutants, affecting the heat dissipation effect and thus reducing the air conditioning efficiency. By spraying and cleaning the outdoor unit 2 in a timely manner, these harsh environments can be effectively dealt with, the impact of external pollutants can be reduced, and the air conditioner can be ensured to maintain a good working condition under various conditions.

[0027] In some other embodiments, a filter 35 is connected in series on the connecting pipe between the water storage tank 31 and the inlet end of the infusion pump 33. During the collection process, the condensed water may carry dust, impurities in the air or tiny particles shed from the indoor unit 1. The filter 35 can intercept these impurities and prevent them from entering the infusion pump 33 and the spray pipe 34, avoiding pipe blockage and ensuring smooth water flow.

[0028] In other embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the external unit 2 includes a bracket 21 mounted on the bottom of the vehicle, a condenser 22 mounted on the bracket 21, and a fan 23 mounted on the bracket 21 and located below the condenser 22; the fan 23 drives the air in the environment to flow through the condenser 22, and the spray pipe 34 sprays water onto the condenser 22. A filter 24 is also installed on the top of the bracket 21, and the spray pipe 34 is located between the filter 24 and the condenser 22. Preferably, the water storage tank 31 and the infusion pump 33 are also installed on the bracket 21 of the external unit 2.

[0029] The bracket 21 integrates the condenser 22, the fan 23 and the filter 24 on the bracket 21 at the bottom of the vehicle. Such a layout is conducive to the overall installation and protection of these key components. The fan 23 drives the surrounding air to flow through the surface of the condenser to improve the heat exchange efficiency. The filter 24 is located on the top of the bracket 21 to block the particles, leaves and other large impurities raised during driving and protect the internal structure.

[0030] In other embodiments, Figure 2 and Figure 3 As shown, the spray pipe 34 includes a manifold connected to the outlet end of the infusion pump 33 and a plurality of shunt pipes led out from the manifold, and a plurality of atomizing nozzles 341 are provided on the shunt pipes. For example, a pair of parallel shunt pipes are led out from the manifold, and are respectively located on both sides of the condenser 22, and the shunt pipes on both sides are provided with atomizing nozzles 341 obliquely downward to spray water onto the condenser 22. After the water flow output by the infusion pump 33 is collected by the manifold, it is distributed to a plurality of shunt pipes, so that the water can be more evenly delivered to different parts of the condenser 22. In particular, when the shunt pipes are arranged on both sides of the condenser and equipped with atomizing nozzles 341 obliquely downward, it can be ensured that every part of the surface of the condenser 22 can be covered by fine water mist, thereby improving the comprehensiveness and efficiency of cleaning and cooling. In addition, the uniform and gentle water mist spraying method has less wear and impact on the surface of the condenser 22, which is conducive to extending its service life.

[0031] In some other embodiments, the external unit 2 further includes an electronic control unit and a temperature sensor disposed on the air inlet side of the condenser 22. The electronic control unit starts the infusion pump 33 after detecting that the temperature measured by the temperature sensor exceeds the preset temperature. In this way, when the ambient temperature is too high, water mist can be used to supply water to the condenser 22 to improve the air conditioning refrigeration effect. When the air conditioner is running, if the ambient temperature is high, usually above 38°, the refrigeration load of the air conditioning system increases significantly and the refrigeration efficiency decreases. At this time, the infusion pump 33 is controlled to start, and the condenser 22 is cooled by evaporation of water mist to absorb heat. When the cooling effect is significant, the fan speed can be appropriately reduced to reduce power consumption.

[0032] In other embodiments, Figure 6 As shown, an overflow valve 311 is also provided on the top of the water tank 31, which allows excess condensed water to flow out from the overflow valve 311 after being input into the water tank 31, ensuring that the condensed water can continue to flow from the indoor unit 1 into the water tank 31 through the drainage pipe 32, avoiding obstruction of condensed water discharge.

[0033] Another embodiment of the present invention also provides a motorhome, integrating all the technologies of the cleanable air conditioner of the above embodiments into the motorhome, wherein the external unit 2 is installed on the frame at the bottom of the motorhome, and the internal unit 1 is installed in the passenger cabin and / or cockpit of the motorhome.

[0034] When cleaning is required, the entire system works as follows:

[0035] 1. Start the cleaning control program: The vehicle's control system starts the cleaning control program when it receives a cleaning instruction. It can be manually triggered through the driver's operating interface or automatically activated according to a preset scheduled maintenance plan.

[0036] 2. First air blowing: The control system sends a signal to activate the fan 23, and the fan 23 rotates to blow air from bottom to top, blowing away the dust attached to the condenser 22 and the debris scattered on the filter 24, and then the fan 23 is turned off.

[0037] 3. Spray: The control system sends a signal to activate the infusion pump 33, and the infusion pump starts working to extract the condensed water that has been collected and purified by the filter 35 from the water tank 31. The pressurized water flow is collected by the manifold and evenly distributed to multiple branch pipes to ensure that the water flow can flow evenly to various areas of the condenser 22. The atomizing nozzle 341 on the branch pipe further atomizes the water flow into fine water mist. These atomized water droplets can adhere to the surface of the condenser 22 more effectively, which not only increases the water coverage area, but also increases the surface area in contact with dirt, thereby more effectively softening and washing away accumulated dust, mud and other pollutants.

[0038] 4. Second blowing: the control system sends a signal to activate the fan 23, and the fan 23 rotates to blow the wind from top to bottom to suck out the softened mud, and then the fan 23 and the infusion pump 33 are turned off.

[0039] When cooling is required, the entire system works as follows:

[0040] 1. Temperature control sensing and response: When the temperature sensor detects that the temperature on the air inlet side of the condenser 22 exceeds a preset threshold (e.g., 38°C), the electronic control unit immediately starts the preset cooling program after receiving this signal.

[0041] 2. Water mist assisted cooling: On the one hand, the electronic control unit activates the infusion pump 33 to extract condensed water from the water tank 31. The pressurized condensed water passes through the spray pipe 34 and the atomizing nozzle 341 to form a fine water mist, which is evenly sprayed onto the surface of the condenser 22. On the other hand, the fan 23 is controlled to accelerate operation to enhance air circulation and improve heat exchange efficiency.

[0042] 3. Real-time adjustment: During the cooling process, the electronic control unit monitors the feedback of the temperature sensor in real time. When the temperature drops to the preset ideal working range (for example, below 34°C), the electronic control unit will stop the water mist spraying and adjust the fan 23 to the normal speed. If the temperature drops to a lower preset value (for example, below 28°C), the fan 23 will be adjusted to a speed lower than the normal speed to reduce the overall energy consumption.

[0043] The above embodiments are exemplary, and their purpose is to illustrate the technical concept and features of the utility model so that people familiar with the technology in this field can understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
