Description

The two temperature control battery saving arrangements of refrigerator

The utility model relates to a kind of temperature control that must use on the household electric refrigerator, the instrument of regulating, in particular, the utility model is about being used for the two temperature control battery saving arrangements of refrigerator on the refrigerator.

Household electric refrigerator has entered huge numbers of families, according to investigations, the vacant phenomenon of the power of refrigerator is very serious, and for example: there is the double-door refrigerator of one 210 liter at certain family, opens and uses, power consumption every day was more than once, and only deposit some cold storing and fresh-keeping food in the refrigerator, and refrigerating chamber is vacant for a long time, particularly season in spring and autumn, this phenomenon is even more serious, do not open a bar? The fresh-keeping bad processing of leftovers, birds, beasts and eggs pickles; Open? Do not need freezing long fresh-keeping foodstuff again, thus use in the refrigerator overwhelming majority times only to use cold storage function, and the freezing function most of the time is vacant.The general user had 6-8 month to use refrigerator in 1 year, refrigerator power is vacant will to be accounted for more than the half the time.Make full use of the refrigerator useful space and freezing, cold storage function, the power of eliminating refrigerator is vacant, saves electric energy, is that the refrigerator users hope.

The purpose of this utility model is to be the vacant difficult point of solution refrigerator power, and provides a kind of refrigerator two temperature control battery saving arrangements that this device can make freezer compartment of refrigerator convert refrigerating chamber to, when the user needs frozen food, can recover freezing function again.

The technical solution of the utility model is such:

The two temperature control battery saving arrangements of the utility model refrigerator contain temperature controller 2, No. two temperature controllers 7, double control switch 1; temperature controller 2, No. two temperature controllers 7 are installed on the refrigerator body inner surface; temperature detection on No. two temperature controllers 7 is partly put into refrigerating chamber; double control switch 1 is connected with external power supply 11; No. one temperature controller 2 is connected between double control switch 1 and the overload protective device 3, and No. two temperature controller 7 is connected between double control switch 1 and the overload protective device 3.

When starting a temperature controller 2, refrigerator has function freezing and refrigeration;

When starting No. two temperature controllers 7, refrigerating chamber has cold storage function.One, No. two temperature controllers take turns to operate, and make refrigerating chamber have freezing and two kinds of functions of refrigeration, have eliminated the vacant phenomenon of refrigerator power, and economize on electricity reaches more than 1/2.

The two temperature control battery saving arrangements of the utility model refrigerator have been compared following advantage with existing temperature control equipment:

1. because double control switch 1 and No. two temperature controllers 7 have been installed, make refrigerating chamber have refrigeration and freezing two kinds of functions, the power of having eliminated refrigerator is vacant.

2. because to have eliminated the power of refrigerator vacant, save power consumption and reach more than 1/2, and prolong refrigerator service life.

3. freezing and two kinds of function conversion of refrigeration of refrigerator are simple to operate, and reliable operation is easy to use.

Below in conjunction with drawings and Examples the utility model is described in detail, parts such as compressor, refrigerator body and other circuit are not described in detail one by one.

Fig. 1 is the refrigerator circuit figure that the two temperature control battery saving arrangements of refrigerator are installed:

The 1-double control switch; Temperature controller of 2-; The 3-overload protective device;

The 4-compressor; The 5-starter; The 6-electric heater; No. two temperature controllers of 7-;

The 8-gate light; The 9-change-over switch; The 10-door lamp switch; The 11-wire socket

As can be seen from Fig. 1: the two temperature control battery saving arrangements of the utility model refrigerator are made up of double control switch 1, temperature controller 2, No. two temperature controllers 7.These three parts all are installed on the inner surface of refrigerator body, and its particular location is mounted near the dividing plate of refrigerating chamber and refrigerating chamber, and the temperature detection on No. two temperature controllers partly stretches into refrigerating chamber, in order to survey and the temperature of control refrigerating chamber.

When double control switch 1 was dialled in the A position, the refrigerating chamber and the refrigerating chamber of refrigerator were worked simultaneously.Double control switch 1 is dialled in the B position, and at this moment, No. two temperature controllers 7 are connected, and No. one temperature controller 2 disconnects, and control the temperature of refrigerating chamber by No. two temperature controllers 7, make refrigerating chamber become refrigerating chamber.

It is to connect like this in refrigerator circuit figure that double control switch 1, temperature controller 2, No. two temperature are driven device 7:

As can be seen from Fig. 1: a kind of situation is that double control switch 1 is connected between temperature controller 2 and the attaching plug 11; be that D on the attaching plug 11 is connected with C on the double control switch 1; binding post A on the double control switch 1 is connected with a temperature controller 2, and temperature controller 2 is connected with E on overload protective device, compressor 4, starter 5, the attaching plug 11.Operating circuit when freezing is such: the E on No. one temperature controller 2 → overload protective device 3 → starter 5 → compressor 4 → attaching plug 11 of binding post A → on the D → double control switch 2 on the attaching plug 11; at this moment, refrigerator has freezing, refrigeration while open function.

Be also shown in from Fig. 1: second kind of situation is: double control switch 1 also is connected between attaching plug 11 and No. two temperature controllers 7; be that D on the attaching plug 11 is connected with C on the double control switch 1; No. two temperature controllers 7 are connected with E on overload protective device 3, starter 5, compressor 4, the attaching plug 11; when double control switch 1 is dialled in the B position; No. 2 temperature controller 7 work; No. one temperature controller 2 disconnects, and quits work, and refrigerating chamber becomes refrigerating chamber.

Operating circuit is such: the E on No. two temperature controller 7 → overload protection arrangement 3 → starter 5 → compressor 4 → attaching plug 11 of B binding post → on the D → double control switch 1 on the attaching plug 11.At this moment refrigerating chamber converts refrigerating chamber to.

Can find out from the composition and the embodiment of foregoing circuit connection layout and three parts, when starting a temperature controller 2, make refrigerator have freezing and cold storage function, start No. two temperature controller 7, can make refrigerating chamber have cold storage function, i.e. one, two temperature controller alternations make refrigerating chamber have freezing, two kinds of functions of refrigeration, have confirmed that the technical scheme of the two temperature control battery saving arrangements of the utility model refrigerator is correct, feasible.

Certainly, the two temperature control battery saving arrangements of this refrigerator also can come to use following form, for example: double control switch, one, No. two temperature controllers are contained in the block terminal, perhaps double control switch, one, No. two synthetic temperature controller of temperature controller is as long as can make freezer compartment of refrigerator have refrigeration and freezing difunctional.These conversion all drop within the protection domain of the present utility model.
