Abstract

The invention discloses a multifunctional heat pump system for a dish-washing machine. The multifunctional heat pump system comprises a hot water cleaning system, a high-temperature sterilizing system, a hot air drying system and a fast cooling system and is characterized in that the hot water cleaning system and the high-temperature sterilizing system are connected with two spraying device waterinlets mounted in the upper portion and the lower portion in the dish-washing machine, and the hot air drying system and the fast cooling system are connected with an orifice plate air supply device air inlet in the upper spraying device in the dish-washing machine; the hot air drying system and the fast cooling system share a set of pipelines and devices; a dish-washing machine inner bottom located below a lower spraying device is provided with a flow guide groove and a wastewater collector, and the flow guide groove is connected with a draining outlet. The multifunctional heat pump system has the advantages that a heat pump can operate in different modes to provide required-temperature heat for the dish-washing machine, energy consumption can be lowered greatly, dried tableware can be fast cooled, the tableware can be taken and used immediately after the work of the dish-washing machine, a user does not need to wait for the tableware to naturally cool, and safety and convenience areachieved.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a multifunctional heat pump system for dishwashers integrating cleaning, disinfection, drying and rapid cooling. Background technique [0002] Air source heat pumps can extract a large amount of heat from the renewable energy—the air—with very little power consumption, and realize the heating function efficiently, and have been widely used in many fields. With the continuous acceleration of people's life rhythm, people's requirements for catering hygiene and food cleanliness and safety are also getting higher and higher. Dishwashers have gradually become a popular choice for fast food restaurants, hotels, restaurants, guesthouses, unit canteens and other public places, as well as urban environmental protection. An indispensable equipment for tableware companies, dishwashers can not only greatly reduce the labor intensity of staff, improve labor efficiency, but also improve cat...
