Shell be mounted in mounting hole, solenoid valve is provided on the shell, the inside of shell is arranged in the single-chip microcontroller；Institute
The internal atmospheric sensor stated is mounted on the inside of refrigerator ontology；Input terminal and the internal atmospheric sensor electricity of the single-chip microcontroller
Property connection, the output end of single-chip microcontroller and solenoid valve be electrically connected, and the single-chip microcontroller is according to the prison for receiving internal atmospheric sensor
Control Numerical Control electromagnetic valve work；A pneumatic parameter value can be set before use in the program of single-chip microcontroller, when single-chip microcontroller connects
When receiving the minimum parameter of numerical value that internal atmospheric sensor monitors lower than setting, single-chip microcontroller just controls solenoid valve opening, allows
Air pressure inside and outside refrigerator carries out neutral equilibrium, when internal atmospheric sensor monitors that the air pressure in refrigerator is higher than the most senior staff officer of setting
When number, single-chip microcontroller just controls solenoid valve closing, thereby realizes the air pressure inside that automation in real time adjusts refrigerator.
It further, further include air pressure partial pressure pipe, the solenoid valve positioned at the outlet of refrigerator body interior is connected with air pressure point
Pressure pipe, air pressure partial pressure pipe can allow outside air to enter refrigerator, and in air pressure partial pressure pipe slowly in and inner air and outer air temperature
Degree avoids the case where local temperature is hurriedly increased or hurriedly reduced inside refrigerator.
Further, further include sealing ring, be provided with sealing ring between the shell and mounting hole, realize and refrigerator is pacified
Fill the sealing effect in hole.
Further, the single-chip microcontroller uses 51 single-chip microcontrollers, good compatibility, computational efficiency height.
It further, further include external pressure sensor, the external pressure sensor is mounted on the outside of refrigerator ontology,
External pressure sensor and single-chip microcontroller are electrically connected, and the single-chip microcontroller is according to internal atmospheric sensor and external pressure sensor
The external and internal pressure difference that monitors controls electromagnetic valve work；It can by the work of refrigerator internal and external pressure difference duty control solenoid valve
Air pressure is more accurately adjusted, environmental field applicatory is wider.
The present invention has the advantages that 1. are adjusted the advantage of the invention is that realizing to automate by the monitoring of baroceptor
Air pressure in refrigerator, avoid in refrigerator air pressure it is too low cause to open the door it is difficult；2. using that can be carried out certainly according to refrigerator internal and external pressure difference
The solenoid valve of dynamicization control, can more accurately realize the air pressure balance inside and outside automation control refrigerator；3. being divided using air pressure
Pipe carries out air pressure neutral equilibrium, avoids the case where partial pressure or temperature rise sharply in refrigerator；4. overall construction design is closed
Reason, practical is an innovative improvement of current low-temp. refrigerator, and market application prospect is wide.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of low temperature constant pressure refrigerator of the present invention.
Specific embodiment
Below in conjunction with attached drawing, the present invention is described in detail:
As shown in Figure 1, a kind of low temperature constant pressure refrigerator, including refrigerator ontology 1, mounting hole 2 and constant pressure automatic device 3, it is described
Mounting hole 2 be arranged on any one face in addition to 1 bottom surface of refrigerator ontology and the shop front, best position is mounted in top surface
On because the air of top surface areas influenced by the hot gas that freezer compressor excludes it is smaller.The constant pressure automatic device 3 is pacified
In mounting hole 2, constant pressure automatic device 3 includes shell 31, single-chip microcontroller 32, solenoid valve 33 and internal atmospheric sensor 34, institute
The shell 31 stated is mounted in mounting hole 2, and solenoid valve 33 is provided on the shell 31, and the single-chip microcontroller is arranged in shell
31 inside, the power supply of single-chip microcontroller, which can connect outside line and also can be used, is mounted directly battery；The air pressure inside passes
Sensor 34 is mounted on the inside of refrigerator ontology 1, for monitoring the air pressure inside refrigerator；The input terminal of the single-chip microcontroller 32 with it is interior
Portion's baroceptor 34 is electrically connected, and the output end and solenoid valve 33 of single-chip microcontroller 32 are electrically connected；32 basis of single-chip microcontroller
The monitoring numerical value of internal atmospheric sensor 34 works to control solenoid valve 33.
Before initial use, an air pressure range value should be first set in the parameter of single-chip microcontroller 32, when single-chip microcontroller 32 receives
When the numerical value monitored to internal atmospheric sensor 34 is lower than the minimum parameter set, single-chip microcontroller 32 just beat by control solenoid valve 33
It opens, the air pressure inside and outside refrigerator is allowed to carry out neutral equilibrium and boost；When internal atmospheric sensor 34 monitors the height of the air pressure in refrigerator
When the highest parameter of setting, single-chip microcontroller 32 just close by control solenoid valve 33, thereby realizes automation in real time and adjusts refrigerator
Air pressure inside.
The mildness of air pressure neutral equilibrium, should also wrap in leakproofness and refrigerator in order to guarantee the installation of constant pressure automatic device 3
