Problems solved by technology

[0003] The opening of the electronic expansion valve in the traditional refrigeration system is adjusted by the temperature detection signal, but for the cold drink machine with a stirring mechanism, the temperature of the cold drink can not accurately express the state of the cold drink, and the temperature of the cold drink is used to control the opening of the electronic expansion valve. The cooling capacity of the compressor can be controlled to affect the required cold drink state

Embodiment Construction

[0027] The present invention is different from the electronic expansion valve in the traditional refrigeration system, which is adjusted by the temperature detection signal to control the output of the compressor. Considering the cold drink machinery with a stirring mechanism, the temperature of the cooled cold drink cannot accurately express the state of the cold drink. Using the temperature of the cold drink to control the opening of the electronic expansion valve to control the compressor cooling output affects the desired cold drink state. Therefore, the present invention uses the output power of the DC stirring motor 10 as the opening adjustment signal of the electronic expansion valve so as to control the cooling capacity output of the fixed-frequency compressor. This application is proposed as follows:

[0028] Such as figure 1 As shown, a cold drink machine with power control electronic expansion valve, including:

[0029] A DC stirring motor 10;

[0030] An electron...

Abstract

The invention discloses a cold drink machine with a power control type electronic expansion valve. The cold drink machine comprises a direct-current mixing motor, the electronic expansion valve, a compressor, a condenser and an evaporator, wherein the compressor, the condenser, the electronic expansion valve and the evaporator are connected in sequence end to end; a power signal of the direct-current mixing motor is transmitted between the direct-current mixing motor and the electronic expansion valve to control the opening degree of the electronic expansion valve so as to adjust the refrigerating capacity output of the compressor. The invention further discloses a control method with the same conception as the cold drink machine.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a cold drink machine with a power-controlled electronic expansion valve. Background technique [0002] Cold drink machinery is a series of food machinery equipment for producing cold drinks. Such as: ice cream machine, Xuerong machine, etc. It is mainly composed of a refrigeration system and a stirring mechanism. The refrigeration system creates a low-temperature environment, and the stirring mechanism is driven by a DC motor to stir the cold food raw materials; [0003] The opening of the electronic expansion valve in the traditional refrigeration system is adjusted by the temperature detection signal, but for the cold drink machine with a stirring mechanism, the temperature of the cold drink can not accurately express the state of the cold drink, and the temperature of the cold drink is used to control the opening of the electronic expansion valve. Therefore, controllin...
