Rainwater filtering device for washing outdoor unit of air conditioner

Abstract

The invention discloses a rainwater filtering device for washing an outdoor unit of an air conditioner. The rainwater filtering device comprises a filtering tank, a liquid accumulation tank and a flowguide water pipe, wherein the filtering tank is arranged just above the liquid accumulation tank; one end of the flow guide water pipe is connected with the upper half part of an outer side wall of the filtering tank; the other end of the flow guide water pipe is connected with the upper half part of the outer side wall of the liquid accumulation tank; a filtering screen is arranged in the filtering tank; the filtering screen is arranged at the lower half part of the filtering tank; a collection opening is formed in the upper surface of the filtering tank; the collection opening is provided with a matched shielding cover plate; the collection opening is connected with a collection pipeline; one end, far away from the collection opening, of the collection pipeline penetrates through the filtering screen and extends into the filtering tank; a blow-down pump is arranged at the lower half part of the outer side wall of the filtering tank; the highest point of the blow-down pump is lower than the lowest point of the filtering screen; the blow-down pump is electrically connected with an external power supply; the blow-down pump is connected with a blow-down pipe; a water outlet pipe isarranged at the lower half part of the outer side wall of the liquid accumulation tank; a switching valve is arranged on the water outlet pipe. By adopting the rainwater filtering device, the application of tap water resources is reduced and the operation and maintenance cost of users is reduced.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner, in particular to a rainwater filtering device for cleaning the outdoor unit of an air conditioner. Background technique [0002] At present, there are more than one million communication network production buildings, aggregation nodes, and base station computer rooms, and millions of air conditioners of various types are used for environmental protection of computer room network equipment, of which more than 90% are split air-cooled air conditioners . The split-type air-cooled air conditioner uses the outdoor condenser to exchange the heat dissipation of the equipment in the equipment room outside the communication equipment room; in many places, due to many factors such as wind and sand, flying dust, and fluff, the outdoor condenser is exposed to the outside, and the fins are often "dirty and blocked" . The fins of the outdoor condenser are "dirty and clogged", which leads to a decrease...

Problems solved by technology

[0004] The present invention solves the problem in the prior art that the distance between the place where the water resource is taken and the place where the air conditioner is installed outside the air conditioner is too far away from the location where water is taken during the cleaning process; the outdoor unit of the air conditioner is usually cleaned with tap water, which wastes tap water resources and increases the cost of the air conditioner. For the problem of operation and maintenance costs, we provide rainwater filtering devices for cleaning the outdoor units of air conditioners. When it is applied, the operation and maintenance personnel can fetch water to clean the outdoor units of air conditioners, avoiding the long distance between the water intake location and the outdoor units of air conditioners and wasting labor, which is beneficial for users to reduce tap water The application of resources reduces the user's operation and maintenance costs and improves the cleaning efficiency of the outdoor unit of the air conditioner
