Indoor unit of air conditioner and air conditioner

Abstract

The invention discloses an indoor unit of an air conditioner and the air conditioner. The indoor unit of the air conditioner comprises a front face plate, a rear back plate, a heat exchanger, a wind wheel, a front volute and a back volute, wherein the front face plate and the rear back plate are oppositely arranged to form an air inlet and an air outlet, the heat exchanger and the wind wheel are located between the front face plate and the rear back plate, and the front volute and the back volute are arranged on the two opposite sides of the wind wheel to form an air channel. The air inlet is located at the upper end of the front face plate and the upper end of the rear back plate and provided with an air inlet grille. The heat exchanger comprises a first heat exchanger, a second heat exchanger and a third heat exchanger, wherein the first heat exchanger, the second heat exchanger and the third heat exchanger are sequentially distributed around the wind wheel from back to front. The third heat exchanger is located between the wind wheel and the front face plate. The horizontal distance between the axis of the wind wheel and the third heat exchanger is 0.4-0.6 times that between the axis of the wind wheel and the front end of the air inlet grille. By the adoption of the indoor unit of the air conditioner and the air conditioner, the air feeding amount of the heat exchanger can be guaranteed, an enough space is formed between the wind wheel and the third heat exchanger to make turbulent airflow stable, and then the noise caused by the fact that the turbulent airflow impacts the wind wheel is lowered.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an indoor unit of an air conditioner and an air conditioner. Background technique [0002] An air conditioner is a device that processes the temperature, humidity, purity and airflow velocity of the air to meet people's production and living needs. With the development of the economy and the improvement of people's living standards, air conditioners have been integrated into our lives, and people pay more attention to the experience of using air conditioners. [0003] Existing air conditioner indoor unit (such as figure 1 As shown) includes a front panel 1 and a rear panel 2, a heat exchanger arranged between the front panel 1 and the rear panel 2, a wind wheel 3, and a front panel respectively arranged on opposite sides of the wind wheel 3 to form an air duct. volute and rear volute, etc., but due to the unreasonable design of the air inlet and outlet ducts, the impact of ...
