Abstract
The utility model which discloses a refrigeration cabinet with a remote sensing device consists of a cabinet body, an evaporator and a circulation blower which are arranged in the cabinet body, a freezer external machine assembly and an electric control device which are arranged outside of the cabinet body, and the remote sensing device which is arranged outside of the cabinet body is connected with the circulation blower through a constant closed relay. When the remote sensing device detects that someone comes close to a certain area in front of the cabinet door, then the constant closed relay can cut off the electric power of the circulation blower and stop the circulation blower rotating in advance, and when the operators open the cabinet door, the cold air with the bad smell and the harmful bacteria is avoided to be blew out of the cabinet, and the operation environment can be improved.
Description
The utility model relates to refrigerator, relates in particular to the air-cooled mortuary refrigerator of band sensoring.
Mortuary refrigerator at present commonly used has air-cooled and two kinds of direct-cooling types, and wherein air-cooled have that refrigeration is fast, low power consumption and other advantages.Air-cooled refrigerator is installed in outer machine assembly of the outer refrigerating machine cabinet of cabinet and electric control gear and constitutes normally by evaporimeter and circulating fan in cabinet, the installation cabinet.During use, when operator's opening door operation, the circulating fan in the cabinet is still being worked, thereby can the cold air in the cabinet be blown out outdoors, and this cold air often has niff and harmful bacterium, has a strong impact on people's physical and mental health.
The purpose of this utility model provides a kind of refrigerator with sensoring, and it can discern the people automatically near the cabinet door, and the power supply of early cut-off circulating fan, makes its stall, and installs, and maintenance is convenient, is fit to existing refrigerator is transformed.
The purpose of this utility model is to realize like this, the refrigerator of band sensoring, include cabinet, be installed in evaporimeter and circulating fan in the cabinet, be installed in outer machine assembly of the outer refrigerating machine cabinet of cabinet and electric control gear, sensoring also is installed outside cabinet, and sensoring is connected with circulating fan by normally closed relay.Sensoring can be installed in the outer cabinet of cabinet and lean the cabinet door on one side, also can be installed in refrigerator indoor suitable position on every side, makes sensoring can monitor the suitable in front of the door scope of refrigerator.Said sensoring can be the automatically-controlled door inductor, OA-51V, the OP-08 that produces as Japanese OPTEX, OA-50C or the like, also can adopt the antitheft inductor of similar principles, as the ECLIPSEEP of Britain PYRONIX company, TWH9251, TWH9231 of China Zhongshan City, Guangdong Province Da Hua Electronics Factory or the like.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of electrical block diagram of the utility model;
Fig. 2 is the another kind of electrical block diagram of the utility model.
According to Fig. 1, sensoring A is built-in with a normally closed relay KA, after alternating current is imported by input 1,2, connect circulating fan through normally closed relay K A by output 3,4, when sensoring A has detected mobile object near the cabinet door during to certain distance, be that output signal arrives normally closed relay KA, the normally closed point of relay K A disconnects the stall of circulating fan dead electricity.After the object that moves left, sensoring A stopped output signal to normally closed relay KA, and it is normally closed to be again closed, the circulating fan work of can switching on.
According to Fig. 2, used sensoring A is the automatic inductor of OA-51V type, and a normally opened relay KA1 has been housed on it, and sensoring A is connected with alternating current input 1,2 by transformer TC, and the fuse FU that it often connects is used to prevent short circuit.Normally closed relay KA is as auxiliary reclay, the output 3,4 of control connection circulating fan, the coil of normally closed relay KA is connected with the normally opened contact of normally opened relay, when sensoring A detects the someone and is close in the cabinet door certain limit, it is the normally opened contact closure that output signal makes normally opened relay KA1, thereby the normally-closed contact of normally closed relay KA is disconnected, and then make the stall of circulating fan dead electricity.In case cabinet operator in front of the door leave, sensoring A stops output signal, and normally opened relay KA1 recovers off-state, and normally closed relay KA also recovers closure state, and the circulating fan energising works on.
The utility model adopts the inductor of infrared technique or microwave technology, utilize it can detect the characteristics of mobile object, in case the cabinet door of people near refrigerator arranged, circulating fan is quit work in advance, avoid the cold air that has bad smell and harmful bacteria is blown out outside the cabinet, improved working environment.Because the utility model can adopt the cabinet mounting means that connects up outward, so installation, maintenance is all very convenient, be fit to existing refrigerator is transformed.
Claims (3)
1, the refrigerator of band sensoring, include cabinet, be installed in evaporimeter and circulating fan in the cabinet, outer machine assembly of the outer refrigerating machine cabinet of cabinet and electric control gear are installed, it is characterized in that cabinet is equipped with sensoring outward, sensoring is connected with circulating fan by normally closed relay.
2, the refrigerator of band sensoring according to claim 1 is characterized in that cabinet that sensoring is mounted in the cabinet place leans one side of cabinet door.
3, the refrigerator of band sensoring according to claim 1 is characterized in that said sensoring is an OA-51V type automatically-controlled door inductor.
