In the traditional air conditioner, electric heating is placed between an evaporator part and an air duct part, when the electric heating is started, indoor cold air enters through an air inlet and then exchanges heat through the evaporator part, and then is sent out of the air conditioner through the air duct after being electrically heated. The installation position of the traditional electric heating influences the air inlet volume and the noise of the air conditioner, and even influences the heating comfort. The air duct can reduce the occupied space in the air duct and increase the air quantity; when heating, with air uniform heating etc. in the wind channel, smooth and easy heat transfer in the wind channel improves heat exchange efficiency, improves the travelling comfort scheduling problem that heats.
This patent concrete implementation shows for example fig. 1, the utility model provides a pair of machine in air conditioning, this machine in includes casing 100 and locates evaporimeter 2 in the casing, fan 3, wind channel part 4, be equipped with air intake 1 on the casing, air outlet 6, wind channel part is formed with the intercommunication air intake between air intake, the air outlet, the wind channel 200 of air outlet, fan 3 is preferably the through-flow fan, arrange in the wind channel of evaporimeter low reaches, the machine in air conditioning is equipped with auxiliary heating equipment, auxiliary heating equipment is heating film 8, the setting is on the wind channel inner wall in fan low reaches.
As further shown in fig. 1, the air duct component 4 includes a volute 7 located between the air outlet surface of the hair styling device and the air outlet of the housing, the fan is enclosed in the volute, and a heating film is attached to the inner wall surface of the volute forming the air duct. Particularly preferably, a heating film is attached to the front volute tongue of the volute, and the heating film completely covers the front volute tongue 5 of the volute.
So when the air conditioner heats, the air that indoor side is colder passes through air intake 1 earlier and gets into the spiral case of wind channel part after evaporator 2 once heat transfer, and wind passes through the spiral tongue after, and the hot membrane of placing in the wind channel the inside in passes through thermal radiation conduction, with the temperature rise on wind channel surface, again with the inboard wind heat transfer in wind channel.
In this patent, the wind channel front volute tongue is covered completely to the heating film, and the heating heat transfer area is big than traditional electrical heating area, when heating, can improve wind channel inboard wind and heating film heat transfer effectively, improves heat exchange efficiency, improves the air-out temperature, cancels former electrical heating structure moreover, can smoothly enter the air, reduces the air inlet windage to a certain extent, increases the amount of wind. This patent is a device that can improve the air-out temperature that heats simultaneously, increases air conditioner wind channel space, increases the amount of wind.
Optionally, the heating film is an electric heating film or a far infrared heating film, and the electric heating film is adopted in the embodiment, so that the heating film is simple, convenient and practical.
Of course, the following further improvements can be made to the above embodiments following the same innovative idea, which can be present alone or in combination:
as shown in fig. 2, an electric heating film is attached to the rear volute tongue of the volute optionally.
Optionally, a heating film may be attached to the air duct component downstream of the fan, such as the side wall surface of the air duct of the rear plate of the air conditioner, and a heating film is attached to the air duct side of the cover plate of the air conditioner.
Optionally, a heating film may be attached to the blades of the fan.
It is also to be noted that:
the utility model discloses still be applicable to on other wind channel parts with wind channel formation confined space, be provided with the heating film on parts such as the back plate of square cabinet-type air conditioner, the apron of mobile air conditioner, fan blade surface. The electric heating film can be arranged on the inner wall surface of the air duct, and can also be arranged on the outer wall surface of the air duct or in the air duct component to transfer heat to air in the air duct in a heat conduction mode. Therefore, the access of the power supply is realized from the outside of the shell, and the device is simple and convenient.
The utility model discloses because the design of heating film for traditional electric heating part (like PTC electric heater) that is located the fan upstream can be left out or design very little and be unlikely to lead to the air current not smooth to influence the uneven size of air-out. Of course, if the space is large enough, it is allowable to adopt the conventional electric heating arrangement shown in fig. 2 in combination with the built-in heating film arrangement of the present invention, that is, an electric heating device, specifically, a PTC electric heating or metal heating tube, is arranged between the outlet of the evaporator and the inlet of the fan volute, in order to further increase the auxiliary heating effect.
Of course, if the internal space of the air conditioner is sufficient, the PTC electric heater and the metal heating tube can be arranged in a rear plate (of a square cabinet machine) and a cover plate (of a mobile air conditioner) in the air conditioner, the surface of a fan blade and other parts in the air conditioner.
To sum up, the utility model discloses the built-in method of heating film on the adoption of heating film, especially the wind channel part that is located the wind channel low reaches not only can practice thrift the air conditioner inner space, can also solve when the electric auxiliary heating of current air conditioner opens, the problem that the air-out difference in temperature is big. So realize increasing the air inlet area, improve heat exchange efficiency, increase the effect of the travelling comfort of heating.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
