Problems solved by technology

During the drying process, the heat of the humid air is gradually transferred to the water in the preheating tank, the temperature of the water in the preheating tank is gradually increasing, and the temperature of the humid air is gradually decreasing, resulting in a gradual decrease in the temperature difference between the air and water, and the heat exchange The effect also gradually decreases
Therefore, the heat exchange effect of this scheme is not ideal, the heat exchange amount is not high, and the drying and energy recovery efficiency is low, which has become an obvious shortcoming of this technical scheme

Abstract

The invention discloses a dish-washing machine. The dish-washing machine comprises a water tank, a main cavity body (14) and an air flue (28) used for recycling heat from the main cavity body (14). The dish-washing machine further comprises a heat pump system; an evaporator (20) of the heat pump system is installed in the air flue (28) to absorb the heat in the air flowing through the air flue (28); a condenser (23) of the heat pump system is provided with a waterway used for absorbing the heat; the waterway is connected with a water tank to form a circulating waterway, so that water in the water tank is heated. By adding the heat pump system, the dish-washing machine can significantly improve drying and energy recovery efficiencies, thereby reaching the purposes of reducing overall power consumption and saving energy.

Description

technical field [0001] The invention relates to the technical field of dishwashers, in particular to dishwashers with energy recovery function. Background technique [0002] Commercial dishwashers refer to dishwashers suitable for commercial use. They are generally used in hotels, restaurants, restaurants and other medium and large catering places. They are characterized by high temperature, disinfection, high intensity, and short-term processing, which can save labor and improve cleaning efficiency. [0003] Each single cycle of a commercial dishwasher is generally about two minutes, mainly including three stages of main washing, rinsing and drying. Commercial dishwashers run continuously for a long time, running for two to three hours each time, and running more than 100 cycles at a time. The water temperature required for washing dishes is high. Generally, the water temperature must be heated to above 80 degrees Celsius. Therefore, how to save energy and improve Energy e...
