Description

Technical Field

[0001] This utility model relates to the field of multi-split air conditioning outdoor unit technology, and in particular to a high-efficiency spray device for cooling and cleaning multi-split air conditioning outdoor units. Background Technology

[0002] A multi-split outdoor unit, also known as a multi-split air conditioning outdoor unit, refers to a central air conditioning outdoor device that can connect to multiple indoor units. It controls multiple indoor air supply units through a single outdoor unit, achieving temperature regulation in multiple areas. A multi-split system, also called a multi-split air conditioning system, is a central air conditioning system that uses one compressor (outdoor unit) to control multiple indoor units. It is widely used in homes, office buildings, shopping malls, hotels, and other places to achieve independent adjustment and energy-saving control of multiple rooms or areas.

[0003] However, traditional cleaning devices are usually unable to efficiently clean dust, impurities and dirt from equipment surfaces. The cleaning process often relies on manual intervention or inefficient spraying methods, resulting in poor cleaning effects and an inability to effectively remove accumulated pollutants. Furthermore, without an effective circulating water system, a large amount of water resources are wasted during the cleaning and cooling process.

[0004] Therefore, those skilled in the art have provided a high-efficiency spray system for refrigerated cleaning of multi-unit outdoor units to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency spraying device for cooling and cleaning multi-unit outdoor units. This device is equipped with a cleaning mechanism. With the separation of the diversion pipe, the water pump can spray liquid from the water tank through multiple nozzles onto the outer walls of the unit casing, thereby cooling and cleaning the equipment. This effectively flushes away dust, impurities, and other dirt, improving cleaning efficiency. It also assists in heat dissipation, maintaining a good operating temperature, preventing overheating, and extending equipment lifespan. The dust and impurities in the cleaned wastewater are intercepted and collected in the collection channel by a glass fiber filter. The water, filtered by the double-layer filter, is then reinjected into the water tank to form a circulating water system, saving water resources.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency spray system for refrigerated cleaning of multi-split air conditioners includes a housing. A cleaning mechanism is provided on the lower surface of the housing. The cleaning mechanism includes a support frame and a distribution pipe. A water tank is fixedly connected to the inner wall of the support frame. A cavity is opened at the rear end of the water tank. A water pump is fixedly connected to the center of the bottom surface of the cavity. A delivery pipe is fixedly connected to the output end of the water pump. A collection trough is opened around the periphery of the upper surface of the water tank. A first filter screen is fixedly connected to all four sides of the inner wall of the collection trough. A collection channel is snapped into the inner wall of the collection trough. A second filter screen is fixedly connected to all four sides of the inner wall of the collection channel. Multiple spray nozzles are fixedly connected to the outer wall of the distribution pipe.

[0008] A cooling mechanism is provided on the upper surface of the casing. The cooling mechanism includes a ventilation slot and a placement block. Multiple guide grooves are opened in the middle of the inner wall of one side of the ventilation slot. An installation frame is snapped into the inner wall of the ventilation slot. A third filter is fixedly connected to the inner wall of the installation frame. A ventilation shell is fixedly connected to the center of the upper surface of the placement block. A fan is fixedly connected to the inner wall of the ventilation shell. A fixing bracket is fixedly connected to the upper surface of the ventilation shell. A fourth filter is fixedly connected to the inner wall of the fixing bracket.

[0009] Through the above technical solution, the device is equipped with a cooling mechanism. With the interception of the third and fourth filters made of polyester fiber, the possibility of air dust entering the casing is reduced, thereby reducing the entry of dust into the condenser, fan and other key components, reducing the risk of dust accumulation and damage, and extending the service life of the equipment.

[0010] Furthermore, the support frame is disposed on the lower surface of the housing, and the middle part of the upper surface of the water tank base is fixedly connected to the housing;

[0011] The above technical solution enables the support frame and water tank base to support the machine casing.

[0012] Furthermore, the diversion pipe is fixedly connected to the upper surface of the placement block, and the upper end of the conveying pipe is fixedly connected to the diversion pipe;

[0013] The above technical solution enables the water pump to deliver water to the distribution pipe through the delivery pipe and spray it out through the nozzle.

[0014] Furthermore, the ventilation slots are respectively formed on the inner walls of both sides of the housing;

[0015] The above technical solution enables the ventilation slot to discharge airflow inside the casing or to allow airflow to enter when the equipment is started.

[0016] Furthermore, the placement blocks are respectively fixedly connected to both sides of the upper surface of the housing;

[0017] The above technical solution enables the fan installed inside the placement block to generate airflow inside the casing.

[0018] Furthermore, a maintenance plate is snapped into the middle of the front outer wall of the housing;

[0019] The above technical solution enables users to maintain and repair the unit components inside the casing by disassembling the maintenance panel.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model proposes a high-efficiency spraying device for cooling and cleaning multi-split air conditioners. The device is equipped with a cleaning mechanism. With the separation of the diversion pipe, the water pump can spray the liquid in the water tank through multiple nozzles onto the outer wall of the casing, thereby cooling and cleaning the equipment, effectively flushing away dust, impurities and other dirt, improving cleaning efficiency, and also assisting in heat dissipation, maintaining a good working temperature, preventing overheating and extending the equipment life. The dust and impurities in the cleaned wastewater are intercepted and collected in the collection channel by the glass fiber filter. The water filtered by the double-layer filter is injected back into the water tank to form a water recycling system, saving water resources.

[0022] 2. This utility model proposes a high-efficiency spray device for refrigeration and cleaning of multi-split air conditioners. The device is equipped with a cooling mechanism. With the interception of the third and fourth filters made of polyester fiber, the possibility of air dust entering the casing is reduced, thereby reducing the entry of dust into the condenser, fan and other key components, reducing the risk of dust accumulation and damage, and extending the service life of the equipment.
