Embodiment Construction

[0009] figure 2 It is a schematic diagram of an embodiment of the present invention.

[0010] exist figure 2 Among them, L and N are single-phase AC power input lines, Cp is the compressor, and the three input lines S, M, and C of the compressor Cp are the starting winding, the main winding and the common terminal respectively, and P is the overload protector of the compressor. H1 is the heater for temperature compensation of the refrigeration appliance. C1 is a capacitor for step-down; U1 is a single-chip microcomputer; D3, R3, C3, D4, and C4 use the positive half cycle of the AC power supply to form a half-wave rectified and stabilized power supply for the above-mentioned single-chip microcomputer with an electronic thermostat with a compressor starting function Power supply for the control system; D1, D2, R2, and C2 use the negative half cycle of the AC power supply to form a half-wave regulated power supply to provide power for the LED lamp group used for internal ligh...

Abstract

An electronic thermostat with a compressor starting function, which consists of a power supply circuit [1], a single chip microcomputer [7], a compressor switch circuit [3], a compressor starting circuit [2], a temperature compensation circuit [4], a temperature adjustment circuit It is composed of detection circuit [5] and LED light group [6]. The thermostat consists of a single-chip microcomputer to form a control system. Its power supply circuit adopts capacitor step-down, and then the positive and negative half-waves are processed separately. After being rectified, filtered and stabilized, it provides power to the LED lamp group [6] used for internal lighting of the refrigeration appliance; there are two connecting wires between the compressor starting circuit [2] and the compressor [Cp], one of which is connected to the compressor starting winding [ S] connection, and the other is connected with the common end [C] of the starting winding [S] and the main winding [M] of the compressor. The thermostat uses a very simple circuit to realize the function of a traditional compressor without power consumption starter on the electronic thermostat. The circuit is simple, the cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to a temperature control device, in particular to an electronic temperature controller of a small refrigeration appliance. Background technique [0002] At present, there are many schemes for using electronic technology to realize temperature control. Most of the temperature control schemes for small refrigeration appliances use traditional pressure thermostats, which have a single function and only realize temperature control, but because of their low cost, they are widely used. In recent years, with the improvement of living standards, people no longer meet the simple temperature control requirements, and some refrigeration appliances have begun to use single-chip microcomputer control systems. In addition to the temperature control function, it also has many other functions, such as temperature display. , touch buttons, etc., but the control of the compressor of the refrigeration appliance is no different from the control of t...
