Problems solved by technology

[0002]In the general air conditioner evaporator, only one fan is installed, and the cooling core and heating core are arranged side by side on the same side of the fan. The heating core has large wind resistance; in addition, the switching between cooling and heating modes of air conditioners is often controlled by valves, such as hot water valves, etc. Valve control is not only unreliable, but also if the valve is broken, switching between cooling and heating modes influence each other

Embodiment Construction

[0010] Such as figure 1 As shown, when cooling, the connecting rod mechanism 2 driven by the motor 1 controls the hot air door 4 to close the heating core 6, and the connecting rod mechanism 2 driven by the motor 1 controls the cold air door 3 to open, and the cold air comes out from the cooling core 5;

[0011] Such as figure 2 As shown, when heating, the linkage mechanism 2 driven by the motor 1 controls the cold air door 3 to close the refrigeration core 5, and the linkage mechanism 2 driven by the motor 1 controls the hot air door 4 to open, and hot air comes out from the heating core 6.

[0012] The present invention is not limited to the above-mentioned embodiments, within the concept scope of the present invention, according to the description of the above description, those skilled in the art can also make some obvious changes, but these changes should fall within the protection scope of the claims of the present invention within.

Abstract

The invention discloses an air conditioner evaporator. A refrigeration core (5) and a heating core (6) are arranged separately. At the cooling time, a hot wind door (4) closes the heating core (6) and a cold wind door (3) is opened. Cold wind comes out of the refrigeration core (5). At the heating time, the cold wind door (3) closes the refrigeration core (5) and the hot wind door (4) is opened. The hot wind comes out of the heating core (6). The cold wind door (3) and the hot wind door (4) are controlled by a link mechanism (2) driven by a motor (1). The cold wind door and the hot wind door can not be opened at the same time. The invention solves the problems of the large windage resistance and lots of valve failures in the prior technology, providing an air conditioner evaporator which has small windage resistance, large input air, high cooling and heating efficiency and good reliability. The air conditioner evaporator can be broadly applied to the air conditioners.

Description

technical field [0001] The invention relates to an air-conditioning evaporator, in particular to the cold-heat conversion control of the air-conditioning evaporator. Background technique [0002] Generally, in the air conditioner evaporator, only one fan is installed, and the cooling core and the heating core are arranged side by side on the same side of the fan. The switching of the cooling system is often controlled by valves, such as hot water valves, etc. The valve control is not only unreliable, but also if the valve is broken, it will affect each other when switching between cooling and heating modes. Contents of the invention [0003] The present invention provides an air conditioner evaporator aiming at the above disadvantages. [0004] An air conditioner evaporator, the cooling core 5 and the heating core 6 are arranged separately. [0005] A further way is that when cooling, the hot air door 4 closes the heating core 6, the cold air door 3 opens, and the cold a...
