Description

A warm air device with air purification function

Technical field

The invention relates to a warm air output device for circulating and purifying indoor air, which can not only deliver warm air with a certain temperature, but also purify the indoor air.

Background technique

Air heaters are generally composed of ventilators, motors and air heaters, and are suitable for indoor environments where air is allowed to recirculate. The air heater dissipates heat, and then the fan sends out, so that the air temperature in the room can be adjusted. But the known warm air equipment generally only has the function of heating, and cannot purify the circulating air. Thermophoresis air purification technology refers to the process of moving particles in the air to cooler areas and depositing them on low-temperature surfaces through artificially created temperature gradients. Due to the impact of excess heat generated by thermophoretic air cleaning on the thermal environment in the room, this technology has not been widely used.

Contents of the invention

In order to overcome the shortcoming of the single function of the current heater, the present invention provides a heater device with air purification function, which integrates the two functions of air purification and warm air output. The device can not only provide warm air in the traditional sense, but also It can purify the circulating indoor air to achieve the dual purpose of controlling indoor temperature and cleanliness.

The basic technical solution adopted by the present invention to solve the technical problem is: a warm air device with air purification function, which mainly includes a casing, a cross-flow fan, a motor, a heating resistance wire, an air inlet and an air outlet. The bottom of the heating resistance wire is fixed on the lower bracket inside the shell, and the lead wire of the heating resistance wire is left at the bottom of the lower bracket inside the shell; the thermophoresis purification module is composed of a metal dust removal tube, a metal tube upper fixing bracket and a metal tube lower fixing bracket, and the metal dust removal The bottom of the tube is fixed on the lower fixing bracket of the metal tube, and the upper part of the metal dust removal tube is fixed on the fixing bracket on the metal tube; the thermophoresis purification module is connected and fixed with the upper bracket in the shell and the lower bracket in the shell, and the heating resistance wire is nested in the metal tube. The center of the dust removal pipe; the cross-flow fan is located at the lower part of the lower bracket in the casing, connected with the motor, and the cross-flow fan is fixed on the bottom plate of the casing; the air outlet is an adjustable air supply angle louver, which is installed on the top of the casing; the air inlet is the inlet The air grille is installed on the side of the bottom of the casing, close to the air inlet position of the cross-flow fan; the upper bracket inside the casing, the lower bracket inside the casing, the upper fixing bracket of the metal tube and the lower fixing bracket of the metal tube are all dendritic grid structures.

The working principle of the above scheme is: after the indoor air passes through the air intake grille, it is sent into the thermophoresis purification module by the cross-flow fan. The heating resistance wire generates heat after being energized, and a temperature gradient is formed between the heating resistance wire and the metal dust removal pipe wall. Part of the air pressurized by the fan passes through the metal dust removal pipe. While being heated, the particles in the air are deposited on the inner wall of the metal dust removal pipe due to thermophoresis, and the other part of the air bypasses through the gap between the metal dust removal pipes. After the air passes through the thermophoresis purification module, it enters the air mixing section on the top of the shell, and the purified hot air is mixed with the bypass air to make the temperature of the outlet air reach an appropriate range. The mixed air is finally sent out through adjustable air supply louvers.

Based on the above technical features, an elevated base can be provided at the lower part of the shell bottom plate, and the air intake grille extends downward to the side of the elevated base. The function is to make the air intake grille higher than the ground and reduce the inhalation of ground dust. As an optimization, the primary filter is inserted between the air inlet grille and the cross-flow fan, and it is suggested that the primary filter is detachable. The function is to perform primary filtration of larger dust particles in the air.

The beneficial effect of the present invention is that the indoor air can be circulated and purified while the warm air is being sent out, and the purification device is easy to disassemble and easy to clean without replacing consumables such as filter screens.
