Technical Field

The invention relates to the field of heating and ventilation equipment, in particular to an air conditioner heat exchanger.

Background

The heat exchanger is one of important components of the air conditioner, dust is easily accumulated on the fins of the component after the component is used for a long time, and the component needs to be cleaned at regular time to ensure that clean and fresh cold and hot air is blown out from the air outlet; and people need to dismantle the air conditioner in the cleaning process, which is very troublesome.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a self-cleaning type heat exchanger for an air conditioner, which can be cleaned automatically and conveniently, and which avoids the inconvenience of disassembling the device for users.

The technical scheme adopted by the invention for solving the technical problems is as follows: the self-cleaning air conditioner heat exchanger comprises heat exchange fins and a heat exchange coil, wherein holes are uniformly distributed on the surfaces of the heat exchange fins; the heat exchange fins are provided with shielding assemblies at air outlet positions, the air outlet areas between every two adjacent heat exchange fins are recorded as air outlet cells, one of every two adjacent air outlet cells is shielded by the shielding assemblies in a cleaning state, and the shielding assemblies do not shield any air outlet cell in a heat exchange state.

Preferably, the shielding assembly can be continuously switched between a cleaning state and a heat exchange state, so that the shielding assembly disappears when the airflow for cleaning the surfaces of the heat exchange fins is generated, and therefore, the vibration effect is formed on the dust on the surfaces of the heat exchange fins, the dust is easy to fall off, and the cleaning efficiency is improved.

Preferably, the shielding component is designed as follows: in every two adjacent heat exchange fins, one of the heat exchange fins is connected with a shielding piece containing a ferromagnetic material through a spring shaft extending along the edge of the heat exchange fin on the air outlet side, and the other heat exchange fin is provided with an electromagnet extending along the edge of the heat exchange fin on the air outlet side; under the heat exchange state, the electromagnet is powered off, so that the movable edge of the shielding piece is far away from the electromagnet under the action of the elastic force of the spring shaft, the shielding of the air outlet grid between the two heat exchange fins is avoided, and under the cleaning state, the electromagnet is powered on, and the movable edge of the shielding piece is in contact with the electromagnet under the magnetic attraction, so that the shielding of the air outlet grid is realized.

Preferably, the shielding component is designed as follows: the shielding component comprises an interval baffle plate which is opposite to the air outlet, and the interval baffle plate can move back and forth along the air outlet direction of the air outlet under the driving of the driving mechanism; and the spacing baffle is transversely and uniformly provided with air outlet holes with the width and the distance equal to those of the air outlet lattices, so that when the spacing baffle moves backwards to the limit position, one of every two adjacent air outlet lattices is just blocked by the spacing baffle, and the other air outlet lattice is just opposite to one air outlet hole. Furthermore, the driving mechanism comprises a sliding sleeve fixed relative to the heat exchange fins and a sliding rod fixed relative to the spacing baffle and capable of sliding back and forth in the sliding sleeve; the sliding rod extends into the sliding hole of the sliding sleeve, the end part of the sliding rod is connected with the bottom of the sliding hole through a supporting spring, the bottom of the sliding hole is provided with an electromagnet, and the sliding rod is made of ferromagnetic materials; therefore, when the electromagnet at the bottom of the slide hole is powered on, the slide rod penetrates into the slide hole, the spacing baffle slides backwards to the limit position, and when the electromagnet is powered off, the slide rod slides towards the outer end of the slide hole under the action of the supporting spring, so that the spacing baffle slides forwards to the limit position.

The invention has the beneficial effects that: in the heat exchange state of the self-cleaning air-conditioning heat exchanger, the shielding component does not shield the air outlet, so that the air-conditioning equipment can normally work; in a cleaning state, one of every two adjacent air outlet grids is shielded by the shielding assembly, and the other air outlet grid can be normally communicated with the outside, so that the air pressure in the adjacent air outlet grids is unbalanced, and further, air flow perpendicular to the heat exchange fins and passing through the holes is generated, and the surfaces of the heat exchange fins are cleaned under the impact of the air flow; therefore, the heat exchanger can be conveniently and automatically cleaned, and the trouble that a user dismantles equipment is avoided.
