air conditioner indoor unit

Abstract

The invention relates to an indoor unit of an air conditioner. The indoor unit comprises a machine shell, a heat exchange device and a an air inlet and an ion air generating device; the machine shellis provided with an air inlet and an air outlet, wherein the air inlet is used for allowing ambient air to enter into the air inlet, the air outlet is used for allowing air flow inside the air inlet to flow out, the air inlet is formed in the rear side of the machine shell, and the air outlet is formed in the front side of the machine shell; the heat exchange device is arranged in the machine shell and is configured to carry out heat exchange with the air flow entering the machine shell through the air inlet; and an ion air generating device is configured to controllably utilize the electric field force to enable the air flow in the machine shell to flow towards the air outlet, the ion air generating device is positioned at the rear side of the heat exchange device, and is provided with aplurality of discharge modules which are arranged in sequence in the front-back direction, each discharging module comprises a metal net extending in a plane perpendicular in the front-back directionand a plurality of discharging pins located on the rear side of the metal net and arranged in an array mode, wherein the discharge pins of every two adjacent discharge modules are arranged in a staggered mode. According to the indoor unit of the air conditioner, soft, uniform and strong air supply can be realized, and the noise in the operation process is very small.

Description

technical field [0001] The invention relates to air-conditioning technology, in particular to an air-conditioning indoor unit. Background technique [0002] Traditional wall-mounted air-conditioning indoor units mostly use downward airflow, which will cause cold or hot air to blow directly to the human body, which is not conducive to user comfort and health. The air outlet of the air conditioner indoor unit is usually provided with a guide plate to adjust the air outlet direction of the air outlet by swinging the guide plate up and down or left and right. However, the adjustment range of this method is limited, and it is difficult to realize the air supply requirements in a wide range. Even if the fluid is raised or blown sideways by some unconventional means on the basis of the traditional wall-mounted air conditioner indoor unit, the loss of wind speed and wind pressure is relatively large, resulting in high power consumption and high noise of the air conditioner indoor u...

AI Technical Summary

Problems solved by technology

[0004] In order to obtain a higher wind speed, it is usually achieved by increasing the voltage in the prior art. However, in the process of increasing the voltage, when the current value increases to a certain extent, there will be a spark discharge phenomenon, which will make the inter-electrode The voltage drops rapidly, resulting in extremely weak or even no ionized wind speed

It can be seen from the above that the air supply speed, air volume and air supply efficiency of the ion air supply module using the pin mesh structure in the prior art are relatively low
