Problems solved by technology

[0007] As we all know: adopting heating desorption to adsorbent material is the method generally adopted by those skilled in the art, in order to overcome the defect that the adsorption type purifier needs to frequently replace the adsorbent material, and according to the method of adsorbent material heating desorption, currently there are public literature records to collect heat A new type of adsorption purifier with desorption function integrated, such as the patent application number: 201510898501.0, a wall-mounted air purifier based on thermal regeneration and its purification method. Users can choose indoor purification or mechanical ventilation according to their needs. When choosing When the indoor purification function is used, the sewage will be discharged after thermal desorption during the working process. When the mechanical ventilation function is selected, the outdoor fresh air will be introduced into the room. However, the wall-mounted air purifier and its purification method have the following defects: When it is attached (heat regeneration mode period), the pressure in the closed airtight cabin may be too high, and because the pressure relief valve for preventing device damage is installed on the wall of the air purification room of the airtight cabin of the purifier to the room, once the pressure is released When the valve is opened to release the pressure, the air with high concentration of pollutants in the cabin will be released to the room, causing secondary pollution in the room, and when the air valve between the air purification room and the heating regeneration room is closed and the heating regeneration room leads The outdoor air valve is closed, that is, when the purifier is in the purification mode, the heating control circuit of the electric heating wire in the heating and regeneration chamber loses control and generates high temperature, and the temperature sensor in the heating and regeneration chamber is damaged. At this time, the closed heating and regeneration chamber generates The pressure may be too high and damage the device, because the pressure relief valve installed on the wall of the air purification room facing the room cannot work at this moment; (2) the dust adsorbed on the coarse filter cannot be discharged to the outside; (3) due to the sewage mode The air valve at the top of the air purification room is opened at the bottom, and the air valve at the bottom of the air purification room is closed, so the desorbed pollutant-containing air in the air purification room cannot be completely discharged, and may be discharged into the room. Form secondary pollution; (4) Since the air valve at the bottom of the air purification room is opened in the fresh air mode, and the air valve at the top of the air purification room is closed, it is impossible for the outdoor fresh air to be purified by the filter module in the main body of the air duct Introduced into the room, but directly into the room without purification by the filter module; (5) Due to the use of pure timing sewage, the timing time may be too long or too short, such as the timing time may be too long in winter, and the timing time may be too short in summer The heat in the cabin can't dissipate

Abstract

The invention discloses a wall-mounted air purifier with a heat regenerating function and a control method thereof. The purifier comprises a closed cabin which is divided into a heating regenerating chamber and an air purifying chamber which are arranged left and right, a flow sensor, a VOCs sensor, a bidirectional fan, an efficient regenerable VOCs and formaldehyde adsorbing material and a roughing filter which are successively mounted in the air purifying chamber from top to bottom, a heating body and a first temperature sensor which are mounted in the heating regenerating chamber from top to bottom, five air valves, a second temperature sensor and a pressure release valve, wherein the air valves control an air duct, the second temperature sensor is mounted inside a room, and the pressure release valve is mounted in the heating regenerating chamber and communicates with the exterior of the room by penetrating a wall. When the pressure release valve releases pressures, no secondary pollution will be generated to the room; the control method comprises the steps of: controlling the duration of pollution discharge time by a method of timing and temperature-sensing to guarantee that the temperature in the cabin is adaptive to the indoor temperature after pollution discharge; and dedusting the roughing filter in real time at a starting up moment and in a working process to guarantee cleanliness of the roughing filter. The wall-mounted air purifier disclosed by the invention is simple in structure, convenient to operate and safe and stable, and can be used for effectively purifying indoor air for a long time.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, and in particular relates to a structural design of a wall-mounted air purifier with heat regeneration and a control method thereof. Background technique [0002] With the rapid development of urbanization in our country, the number of new buildings is huge every year, and more and more new decoration materials and chemical products are used in interior decoration. These new interior decoration materials often release a large amount of pollutants such as volatile organic compounds (VOCs) and formaldehyde, causing serious indoor pollution. According to statistics, after decoration, most of the formaldehyde and VOCs content in newly built houses exceeds the standard. [0003] Volatile organic compounds (VOCs) and formaldehyde significantly affect people's comfort, health and work efficiency. Volatile organic compounds cause sensory stimulation to the human body, make the human bod...
