Specifically, the steam emission assembly 1 is provided with a steam jet orifice 4, the steam jet orifice 4 is arranged to jet steam or a gas-liquid mixture to the gas pipe cavity 3, the steam emission assembly 1 drives the steam jet orifice 4 to move on the air inlet side of the gas circulation cavity through a motor, and the jet range of the steam or the gas-liquid mixture covers the whole air inlet side of the gas circulation cavity. The steam jet orifice 4 can be programmed to control a movement route through a PLC (programmable logic controller) or a single chip microcomputer, and the steam jet orifice 4 is driven by a motor to move on the air inlet side of the gas circulation cavity according to a set route, such as a 'return' shape or a snake-shaped route, so as to ensure that the air inlet side of the whole gas circulation cavity is cleaned and covered.

The on-line steam cleaning assembly of the present invention is particularly suitable for use in central heat pump air heat exchangers. As shown in fig. 3, the gas tube cavity 3 in the cleaned gas circulation cavity is a heat pump air heat exchanger 2, and the gas flow passes through the heat pump air heat exchanger and passes through the zigzag-shaped gas flow passage, so that the inside of the heat pump air heat exchanger is cleaned and defrosted comprehensively.

Specifically, the gas tube cavity 3 comprises a fold-line-shaped gas flow channel formed by combining a plurality of groups of fins, and the steam jet orifice 4 is arranged to jet steam or gas-liquid mixture into the fold-line-shaped gas flow channel. The fold-line-shaped airflow channel is formed by the gaps of the fins of the heat pump air heat exchanger 2. The fold-line-shaped airflow channel in the air conditioner can increase the heat exchange area and improve the heat exchange efficiency of the air conditioner, and because the deposit stain degree of the fold-line-shaped airflow channel is higher, the traditional cleaning mode cannot clean the fold-line-shaped dead angle position all around, therefore, the steam cleaning is adopted, and the effect is better.

More importantly, the heat pump air heat exchanger 2 is easy to frost or freeze when in heating operation in winter, and the operation of the whole heat pump equipment is influenced. Because ice crystals or ice are generated when the heat pump air heat exchanger 2 is frosted, the ice crystals or ice can be regarded as a special pollutant to be cleaned and removed, so that the ice formation or defrosting can be inhibited. The steam jet orifice 4 is arranged to jet steam or a gas-liquid mixture into the zigzag-shaped airflow channel, and because the steam or the gas-liquid mixture is in a high-temperature and high-pressure state, ice crystal nuclei can be rapidly removed, the growth of the crystal nuclei can be prevented, the ice crystals can be melted, frosting is removed, and the normal operation of the heat pump main machine is ensured.

Further, the surface of the fin of the heat pump air heat exchanger 2 is at least partially coated with a hydrophobic material layer. The hydrophobic material layer can ensure that steam is condensed to form water drops, so that the steam can be conveniently discharged out of the heat pump air heat exchanger 2 under the impact of the steam, and in addition, because the moisture is less remained after the high-temperature and high-pressure steam is cleaned, the condensed water is also discharged out of the heat pump air heat exchanger 2 under the impact of the steam, the surface of the heat pump air heat exchanger 2 is easy to dry and is not easy to form ice. Because the air circulated by the external machine of the heat pump air heat exchanger 2 is outdoor air, most pollutants on the surface of the heat exchanger after steam cleaning are condensed and settled due to high humidity, and therefore, a steam receiving component is not arranged at the air outlet of the heat pump air heat exchanger 2 any more.

The invention is especially suitable for cleaning, inhibiting frosting and defrosting of air heat exchange assemblies in various central air-conditioning air conditioners, can work intermittently to realize efficient online cleaning of the heat exchange assemblies in practical application, greatly saves maintenance cost, ensures normal running of equipment without freezing, realizes sustainable use of the heat exchange assemblies, solves the industrial problem and meets the requirement of automatic cleaning of the cleaning assemblies.

Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
