Air conditioner indoor unit

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner indoor unit. A coil pipe of a heat exchanger is outwards diffused from a liquid distribution component to a refrigerant output pipe, so that multi-section connecting pipes of the coil pipe can form a larger frame structure together; heat exchange positions of the heat exchanger are spread and distributed, and heat exchange positions of the coil pipe are thereby dispersed in the air flow; and heat exchange uniformity of the heat exchanger and the air flow is increased. According to the diffusion frame structure, arrangement space of fins is increased, and heat exchange area is increased; namely, heat exchange performance of the heat exchanger is obviously improved by diffusion arrangement of the heat exchange positions and enlargement of the heat exchange area. In addition, a sterilization purification module is arranged at an air inlet of the air conditioner indoor unit, sothat indoor air can be effectively circulated, sterilized and purified during operation of the indoor unit; cleanliness of indoor air is improved; and air pollutants such as bacteria and dust in the air are reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner indoor unit. Background technique [0002] As air conditioners are widely used in thousands of households, users have higher and higher requirements for the performance of air conditioners. Take the cabinet air conditioner as an example. Usually under the same conditions, the performance of the cabinet air conditioner depends on the heat exchange efficiency, and the heat exchange efficiency is directly related to the heat exchange area. The larger the heat exchange area, the higher the heat exchange efficiency. high. [0003] Usually, the structure and arrangement of the heat exchanger directly determine the size of the heat exchange area and the heat exchange efficiency. In existing cabinet-type air conditioners, the heat exchanger is usually placed obliquely in the air conditioner shell or attached to the air inlet. Usually, in order t...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the heat exchanger of the existing air conditioner is difficult to uniformly exchange heat with the air flow and the heat exchange effect is not ideal, the present invention provides an air-conditioning indoor unit. The machine includes a housing, a sterilization and purification module arranged in the housing, a water receiving tray, a heat exchanger and an air blower, the water receiving tray is arranged below the heat exchanger, and the housing is provided with The air inlet and the first air outlet, the heat exchanger includes a liquid separation member, a refrigerant output pipe, a coil and fins, the liquid separation member and the refrigerant output pipe are arranged up and down, and the coil includes a multi-section connection and the two ends of each section of the connecting pipe are respectively connected to the liquid separating member and the refrigerant output pipe, the fins are arranged on the multi-section connecting pipe, the shape of the refrigerant output pipe is non-linear, The multi-section connecting pipe is arranged to spread outward from the liquid separating member to the refrigerant output pipe
