Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] The invention discloses an embedded air conditioner, which comprises: a casing whose upper surface is fixed to the wall surface of the ceiling to form the appearance of an indoor unit, and an exhaust port is arranged on the side wall; it is arranged inside the casing to cool indoor air a heat exchanger; a blower fan that is used to draw indoor air and deliver the indoor air to the heat exchanger for cooling, and then blow the cold air to the indoor; and a front panel that is arranged on the bottom surface of the casing and forms an air inlet.

[0019] figure 2 It is a schematic diagram of a panel with an indicating device installed on the decorative panel of the present invention; image 3 It is a flowchart of negative pressure detection in the air return port of the present invention.

[0020] Such as Figure 2-Figure 3 As shown, the...

Abstract

The invention discloses a clean prompting method of an indoor machine filter screen of an embedded type air conditioner, comprising the following steps: an air conditioner starting step, a sensor detecting step and a prompting step, wherein the sensor detecting step and the prompting step are as follows: a pressure sensor is started; the pressure sensor is tested; a detecting result and a negative pressure default value are compared in an air outlet; when a test result is larger than the negative pressure value, a green indicator lamp lights on a decoration panel, and the pressure sensor sequentially tests again; and when the test result is smaller than the negative pressure value, a red indicator lamp lights on the decoration panel and prompts that the filter screen needs to be cleaned. After the air conditioner is started, a negative pressure condition in an air return hole is detected by the pressure sensor and is displayed by the indicator lamps arranged on the decoration panel, the filter screen can be cleaned in time. The clean prompting method of an indoor machine filter screen of an embedded type air conditioner not only can effectively ensure the refrigeration effect of the air conditioner, but also can save energy resources and also greatly increase the heat exchange effect.

Description

technical field [0001] The invention relates to a split type air conditioner, in particular to a cleaning prompt method for the filter screen of an indoor unit of an embedded air conditioner. Background technique [0002] Generally, an air conditioner is composed of a heater, a refrigerator, a purifier, etc., which can cool, heat or purify indoor air, and create a suitable indoor environment for users. [0003] Air conditioners can generally be divided into split air conditioners and integrated air conditioners. Split type air conditioners and integrated type air conditioners have the same function. The split-type air conditioner is equipped with an indoor unit capable of cooling / heating on the indoor side, and an outdoor unit capable of heating / cooling and a compressor is installed on the outdoor side, and the outdoor unit and the indoor unit are connected by refrigerant pipes. The outdoor unit of the air conditioner is provided with a condenser (outdoor heat exchanger) a...
