Abstract
The utility model discloses a freezer security protection device belonging to refrigeration security protection equipment of a freezer. The utility model comprises a defrosting temperature switch which is arranged on an evaporator to collect the evaporator temperature, a shunt tripping device, a circuit breaker, a warning circuit and an alarm. The defrosting temperature switch is electrically connected with a coil of the shunt tripping device. The shunt tripping device is connected with the circuit breaker by a link mechanism. The alarm is connected with the circuit breaker by an auxiliary contact which is integrated with the circuit breaker. When the temperature collected by the defrosting temperature switch exceeds the set point, the defrosting temperature switch outputs a switch value to energize the shunt tripping device coil to work. The circuit breaker is tripped off by the linking mechanism, the circuit supply power is cut off, and the load can not work by powering off, safe and reliable protection for the freezer can be achieved. The freezer security protection device has the advantages of simple structure and easy operation. The freezer security protection device can put an end to fire accidents caused by out of control of defrosting or other accidents of the freezer refrigeration equipment.
Description
Technical field
The utility model relates to a kind of freezer refrigerating protection equipment, specifically is a kind of freezer safety guard, is used for freezer refrigerating equipment and causes temperature too high and then cause the generation of fire or other accidents because of defrost is out of control.
Background technology
In order to guarantee that freezer has good refrigeration, the defrost function is an indispensable basic function in the freezer safe operation.In defrost process, can't stop, certainly will cause storehouse temperature to raise because of a variety of causes causes defrost, heavy then can initiation fire even the generation of human casualty accident.Light then to cause article losses such as the food deposited in the loss, particularly storehouse of equipment and freezer itself, medicine, vaccine all be huge generally, this is a great problem that perplexs freezer engineering merchant and user at present.
How safe and reliable the safeguard protection of realization freezer be the previous problem demanding prompt solution of order.Defrost control is to realize moving by the break-make of controlling A.C. contactor controlling basically in the present Cold Storage Control System.Controller breaks down or is subjected to extraneous interference and causes work malfunctioning or the adhesion of A.C. contactor contact, coil fault and other mechanical breakdowns of A.C. contactor to cause contact to throw off, and all can cause the unsafe problems of freezer.Wherein, controller failure and malfunctioning ratio in accident are higher, and what time the appearance of freezer fault is caused by above mostly.
Summary of the invention
The purpose of this utility model provides a kind of freezer safety guard, is used to overcome freezer refrigerating equipment and causes the too high accident that takes place of temperature because of defrost is out of control.
The utility model is achieved by the following technical solution: a kind of freezer safety guard; comprise and be placed on the defrost temperature switch that is used to gather evaporator temperature on the evaporimeter; shunt release, breaker, warning circuit and alarm; the defrost temperature switch is electrically connected with the coil of shunt release; shunt release and breaker link together with linkage, and alarm is by being connected with breaker with auxiliary contact that breaker is connected as a single entity.
Its operation principle is: when the temperature that collects when the defrost temperature switch exceeded setting value, switching value of defrost temperature switch action output made the action of shunt release coil electricity.By linkage, thereby make circuit breaker tripping line disconnection power supply, thereby load reaches the protection safe and reliable to freezer because of cutting off the power supply for working.In circuit breaker tripping, with the auxiliary contact conducting that breaker is connected as a single entity, alarm powers alarm.
Good effect of the present utility model is: simple in structure, easy to use.Can stop the fire that freezer refrigerating equipment causes because of defrost is out of control or the generation of other accidents.
Description of drawings
Fig. 1 is the utility model structural principle schematic diagram;
Fig. 2 is the another example structure principle schematic of the utility model.
Among the figure: 1, evaporimeter, 2, the defrost temperature switch, 3, shunt release, 4, breaker, 5, linkage, 6, auxiliary contact, 7, alarm, 8, the defrost temperature switch, 9, the storehouse temperature controller, 10, freezer, 11, load.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Be separately to the defrost temperature detection and the scheme that defrost is protected to freezer as shown in Figure 1.A defrost temperature switch 2 that is independent of the freezer refrigerating system is positioned over the temperature that is used for constantly detecting evaporimeter 1 on the evaporimeter 1, defrost temperature switch 2 can be an electronic type or mechanical, when exceeding setting value, switching value of defrost temperature switch 2 action outputs makes the coil electricity action of MX shunt release 3; MX shunt release 3 reliably links together with QF breaker 4, during MX shunt release 3 action by and QF breaker 4 between linkage 5, thereby make QF breaker 4 dropout line disconnection power supplies, thereby load 11 reaches the protection safe and reliable to freezer because of cutting off the power supply for working; When QF breaker 4 was threaded off, with OF supplementary module 6 conductings that QF breaker 4 is connected as a single entity, BL alarm 7 powered alarm.
Be another embodiment of the present invention as shown in Figure 2, in the present embodiment, be provided with the system of temperature in the detection freezer of forming by defrost temperature switch 8 and K2 storehouse temperature watch-dog 9 in parallel with defrost temperature switch 2 again, this system can constantly detect the temperature in the freezer by being loaded on freezer 10 inner any positions.Be positioned over defrost temperature switch 2 on the evaporimeter 1 when realizing jointly to defrost storehouse temperature, evaporimeter 1 defrost temperature carry out integrated protection.The independence and the defrost temperature switch outside the Cold Storage Control System 2 that are positioned on the evaporimeter 1 constantly detect evaporimeter 1 temperature, and simultaneously, the freezer defrost temperature switch 8 that is independent of outside the Cold Storage Control System that is placed in the freezer constantly detects temperature of ice house.When defrost, interior any one temperature of defroster or freezer exceeds the setting limiting value, and (this limiting value is not the limit high temperature that operate as normal can reach, but the high temperature that just may occur when having only defrost to break down) time, defrost temperature switch 2 or switching value of freezer defrost temperature switch 8 action outputs make the 3 coil electricity work of MX shunt release.Thereby MX shunt release 3 is threaded off with QF breaker 4 and is cut off power supply, thereby load 11 realizes the protection safe and reliable to the freezer defrost because of outage can't continue the defrost heating; When QF breaker 4 was threaded off, with OF supplementary module 6 conductings that QF breaker 4 is connected as a single entity, BL alarm 7 powered alarm.
As alarm is placed on control centre, then can realize the fault remote monitoring.
