Description
Technical Field
The invention belongs to the technical field of indoor air purification, and particularly relates to a wall-mounted air purifier for heat regeneration, wherein a heating regeneration chamber and an air purification chamber are vertically arranged from left to right, and only one fresh air/sewage discharge common air channel is arranged outside the heating regeneration chamber and the air purification chamber, and an implementation method of the wall-mounted air purifier.
Background
In the prior art, aiming at a heat regeneration wall-mounted air purifier with a heating regeneration chamber and an air purification chamber which are vertically arranged at the left and the right and only have one fresh air/sewage discharge common air channel to the outside, the defect that dust adsorbed on an air purification module and sewage in the heating regeneration chamber cannot be brought out of the outside synchronously when the air purification chamber discharges sewage exists. For example, in 201510898501.0, the wall-mounted air purifier based on thermal regeneration and the purification method thereof have the advantages that pollution discharge performance is sacrificed, and the air purification chamber is subjected to pollution discharge in a gas rebound mode, so that the defects that the polluted air in the regeneration chamber cannot be discharged to the outside when the air purification chamber is subjected to pollution discharge before the application date, and the problem of dust on the output purification module is not considered in the pollution discharge process are overcome. In order to overcome the defects and problems of the wall-mounted air purifier based on thermal regeneration and the purification method thereof of the application No. 201510898501.0, the technical scheme of pollution discharge is improved in the subsequent prior art, the technical scheme that the air purification chamber discharges pollution to bring out heating regeneration indoor pollution air to the outside in a gas downstream mode without influencing the pollution discharge performance is adopted by correspondingly controlling the opening/closing of a fan and an air valve, so that the air purification chamber is effectively discharged, the technical scheme of time sectional type is adopted in the pollution discharge technical scheme, the technical scheme that the air purification chamber discharges the heating regeneration indoor pollution air to the outside in the first time stage is adopted in the first time stage, the technical scheme that the air purification chamber discharges the dust on the purification module is brought out in the second time stage is adopted in the second time stage, and the purification module in the purification stage is timely and effectively adsorbed after the air purification chamber discharges the pollution, and after the second time period, the temperature measurement is connected, and the technical scheme of continuously discharging the sewage to the air purification chamber and bringing the dust out of the purification module is adopted, so that the sewage discharge is finished when the room temperature is reached. However, because the first time period brings the sewage in the air purification chamber out of the heating regeneration chamber to the outside, when the timing is finished, if the temperature of the purification module does not reach the gradual room temperature, residual sewage can be generated in the heating regeneration chamber, if the purification module reaches the gradual room temperature, the subsequent period adopts the technical scheme that the sewage in the air purification chamber brings the dust in the purification module out, which only can play a role of simple superposition, namely only plays a technical effect of dust removal on the purification module, and prolongs the whole time of the sewage discharge process of the air purification chamber, so that the air purification chamber with effective sewage discharge is caused, and the air purification chamber cannot return to the purification stage in time to purify the indoor air. And because the device size, fan amount of wind and purification module characteristic etc. are different, lead to the timing time of first time stage to be difficult to select effectively, although after the first time stage was ended, its dirty gas of heating regeneration indoor residue can not influence the air purification room to the purification of indoor air, but influences the new trend. For example, a wall-mounted air purifier based on thermal regeneration and a purification method thereof under the application number of 2016107072052, a wall-mounted air purifier based on thermal regeneration and a control method thereof under the application number of 2016107427810, a wall-mounted air purifier under the application number of 2016108466117 and an implementation method thereof, etc., have the above-mentioned drawbacks in the technical scheme of pollution discharge.
