Abstract

The utility model provides a refrigerating freezing type electric freezer, which has refrigerating/freezing conversion function. The refrigerating freezing type electric freezer comprises a refrigerating cabinet body, a cabinet cover, a refrigerating system, and a function conversion control circuit. The utility model is characterized in that the cabinet body is provided with a temperature display screen and a function conversion control switch which is composed of three electronic key switches; the inner wall of the cabinet body is provided with sensing elements of a temperature measurement circuit. The mechanical structure and the refrigerating system of the existing ordinary electric freezer do not need changing for the utility model, and the conversion of the refrigerating and freezing function control can be realized by a single chip computer and function control switches.

Description

Refrigerating formula ice box

The utility model relates to a kind of refrigerating formula ice box with refrigerating translation function.

Along with the raising of living standards of the people, ice box is the same with refrigerator to have become indispensable household electrical appliance in people's family daily life.Yet existing ice box only has the function of frozen food, and it will be changed into the ice box with cold storage function, must structurally make bigger change.As disclosed among the Chinese patent CN2035863U " a kind of how warm ice box ", it is to have added totally-enclosed valve pipeline structure in totally enclosed refrigeration system, by the temperature that draught excluder is regulated each cold house in the how warm refrigerator-freezer artificially, reaches the purpose of refrigeration.This refrigerator temperature adjustment low precision, pipeline is many, complex structure and cost are higher, so be difficult to promote the use of.

The purpose of this utility model provide a kind of simple in structure, good reliability, and can be very convenient and realize the refrigerating formula ice box of its freezing and refrigeration function conversion exactly.

Technical solution adopted in the utility model is: by the high-precision electronic sensor collecting temperature parameter that is arranged in the ice box, handle by set computer, by electronic operation switch adjustment control parameter, to reach freezing control and the conversion that refrigerates control.

The utility model has the advantages that: need not do any change the frame for movement and the refrigeration system of original ice box, and only need be by the simple operations of electronic switch, can realize the freezing control of ice box and the conversion of refrigeration control, but also can make the user understand the duty and the control temperature of ice box very easily by the display screen that is added in the ice box outside.

Concrete structure of the present utility model is as shown in drawings:

Fig. 1 is a contour structures schematic diagram of the present utility model

Fig. 2 is circuit controling line of the present utility model road figure

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:

Refrigerating formula ice box includes Refrigerating cabinet body, cabinet lid, refrigeration system and function conversion control circuit four major parts.On cabinet, be provided with temperature display 1 and function conversion controling switch 2.Function conversion controling switch 2 is made up of refrigeration, the conversion of freezing, freezer three Electronic Keying K switch 1, K2, K3.At the inwall of cabinet, be provided with the sensing element B of temperature measurement circuit, sensing element B can be that the end of three Electronic Keying K switch 1 of electron temperature biography, K2, K3 is connected with the base stage of triode T2, T3, T4 respectively, the other end is connected with VDD by R16; At the inwall of cabinet, be provided with the sensing element B of temperature measurement circuit, sensing element B can be electronic temperature transmitter or semiconductor transducer.

The function conversion control circuit of refrigerating ice box is made up of rectifying and voltage-stabilizing memory circuit, sensor temperature measurement circuit, executive circuit and operation display circuit and CMOS single-chip microcomputer IC1.CMOS single-chip microcomputer IC1 is a central data processor.The rectifying and voltage-stabilizing memory circuit adopts standard type circuit commonly used, the rectification circuit that it mainly is made up of D1, D2, D3, D4 and be made up of the voltage stabilizing memory circuit that A1, C1 constitute.The sensor temperature measurement circuit is by sensing element B (electronic temperature transmitter or semiconductor temperature sensor), operational amplifier IC2, IC2 ', and C2, R1, R2, R3, R4, R5, R6, R7 constitute.Executive circuit adopts standard type circuit commonly used, and by triode T1, diode D5, and relay J and compressor M form.The operation display circuit is made of three triode T2, T3, T4 and two charactrons, three LEDs 1, LED2, LED3 and three Electronic Keying K switch 1, K2, K3.Charactron is used to show that refrigerator is in the temperature in which kind of state and the cabinet; Still artificial setting of LED 1 expression Automatic Control controlled, and LED2 represents that whether compressor is kept in motion, and LED3 represents that refrigerator-freezer is in the defrost state.

Working method of the present utility model is achieved like this:

Connect power supply, provide suitable operating voltage to single-chip microcomputer through transformation rectification and mu balanced circuit.At this moment, ice box directly enters freezing duty.Display screen shows freezing control character and freezing duty.The sensing element B-temperature sensor that is arranged at the refrigerator inwall becomes it into voltage signal by variation of temperature, and through secondary computing amplification, be input to Chip Microcomputer A/D mouth, single-chip microcomputer compares this signal and present set duty, export to and carry out a mouthful PA7, whether decision compressor M works.

When the user need be adjusted to cold storage function, can operate the K1 key, display screen demonstrates the symbol that allows adjustment.At this moment, can pass through the K2 key operation, change it and become the refrigeration control character, operate the K3 key again and add their confirmation, ice box then is directly changed into the refrigeration duty.Otherwise, then can repeat to refrigerate the adjustment of freezing duty.
