Detailed Description
The invention is described in further detail below with reference to the attached drawings and detailed description:
Example 1
This embodiment 1 describes a mechanical temperature control circuit.
Referring to fig. 2, a mechanical temperature control circuit includes a power plug 201, an illumination lamp 202, a temperature controller 203, a compressor 204, a linkage switch 205, and the like. Wherein:
The illumination lamp 202 is located on a branch, which is defined as branch number one Q1. The temperature controller 203 is located on the other branch, defining the branch as a branch No. Q2. The branch Q1 and the branch Q2 are different branches.
The ganged switch 205 selects one of the branches to be connected to the mechanical temperature control circuit.
For example, the ganged switch 205 selects the first branch Q1 to be connected to the mechanical temperature control circuit, and at this time, the power plug 201, the ganged switch 205, the first branch Q1, and the compressor 204 form a series circuit.
When the first branch Q1 is connected to the circuit, since the lamp 202 and the compressor 204 are connected in series, the lamp 202 and the compressor 204 need to share the voltage.
And the voltage across the compressor 204 is less than the starting voltage of the compressor 204 when it is operating normally, thus stopping operation.
If the compressor 204 is already in the off state before the door is opened, the off state that the compressor 204 originally maintains will not change when the door is opened (the illumination lamp 202 is opened).
When the ganged switch 205 selects the branch Q2 to be connected to the mechanical temperature control circuit, the power plug 201, the ganged switch 205, the branch Q2 and the compressor 204 form a series circuit.
Since the thermostat 203 is connected in series with the compressor 204, the state control of the compressor 204 is restored.
Alternatively, the compressor 204 can be prevented from operating when the desired temperature is not reached in the housing, i.e. the thermostat 203 is in a closed state. When the first branch Q1 is turned on, the illumination lamp is short-circuited by the temperature controller 203, and thus cannot be operated.
Preferably, the ganged switch 205 in this embodiment 1 employs a single pole double throw switch.
In addition, the mechanical temperature control circuit further comprises a compensating branch Q3 connected in a series circuit, and a compensating switch 206 and a refrigerating chamber heating wire 207 (same as the prior art) are arranged on the compensating branch Q3.
The embodiment 1 can well ensure that when the door is forgotten to be closed, namely, the illumination lamp 202 is turned on, the compressor 204 is controlled to stop working, and the waste of electric energy caused by continuous working of the compressor 204 is avoided.
In addition, the improvement of the temperature control circuit does not influence the normal operation of each component and the normal logic control of each component.
