Description

A outer machine of protection casing and air conditioner for outer machine of air conditioner

Technical Field

The utility model relates to an outer machine protection technical field of air conditioner, concretely relates to outer machine of air conditioner that protection casing and applied this protection casing.

Background

An Air Conditioner (Air Conditioner) is a device that manually adjusts and controls parameters such as temperature, humidity, cleanliness, and flow rate of ambient Air in a building/structure. The air conditioner generally comprises an inner unit and an outer unit, wherein the outer unit mainly comprises a shell, an air inlet and an air outlet are formed in the shell, a compressor, a condenser and an axial flow fan are arranged in the shell, the condenser is mostly of a fin coil type structure and is arranged close to the air inlet, and the axial flow fan is arranged close to the air outlet. The working principle of the air conditioner outdoor unit is as follows: the compressor compresses low-temperature and low-pressure gas into high-pressure and high-temperature gas, the high-pressure and high-temperature gas is sent into the condenser, external air enters the condenser from the air inlet to be subjected to heat exchange to become high-temperature air, and then the axial flow fan dissipates heat of the condenser to enable the high-temperature air to be discharged from the air outlet.

Because the outdoor unit of the air conditioner is hung outdoors for a long time and is subjected to sun, rain and wind dust erosion, the condenser fins are exposed in the air, a large amount of dust is easily accumulated on the condenser fins to block the condenser fins, the heat exchange of the outdoor unit of the air conditioner is influenced, and the normal service life of the air conditioner is further influenced. Generally, a dust hood is required to cover the air conditioner external unit to prevent dust from entering the air conditioner external unit.

The patent No. ZL201921449346.4 (No. CN210373836U) discloses a dustproof partition board for an external unit of an energy-saving air conditioner, which includes a fixing plate and two symmetrically arranged supporting tubes, wherein the two supporting tubes are located on the left side of the fixing plate, a first ventilation member is installed between the two supporting tubes and the fixing plate, the first ventilation member includes a plurality of first rotating thin plates which are sequentially distributed from top to bottom, a second ventilation member is installed between the two supporting tubes, and the second ventilation member includes a plurality of second rotating thin plates which are sequentially distributed from top to bottom; when the air conditioner outer unit works, the first ventilation component and the second ventilation component rotate synchronously to be opened to form an air channel, circulation of air flow is achieved, when the air conditioner outer unit does not operate, the first ventilation component and the second ventilation component rotate to be closed, and an air inlet and an air outlet of the air conditioner outer unit are shielded. This dustproof baffle can effectively separate the dust and form the protection to outer machine inside condenser and the axial fan of air conditioner, however, this dustproof baffle's use can reduce the outer machine inside and outside gas exchange rate of air conditioner, causes the outer machine inside temperature of air conditioner higher easily, influences the condenser heat transfer and then influences the outer machine's of air conditioner system efficiency.
