Abstract
The utility model relates to a two-storage temperatures refrigerator. In the utility model, the bottom of the refrigerating chamber of the refrigerator is provided with an electric heater (2) controlled by a thermostat (8). For example, an electric heating wire which is in a shape like the Chinese character 'kou' or 'ao' is tightly clung to the surface of the liner (3) of the refrigerating chamber; so the utility model has the advantages of simple structure, convenient manufacture, high safety, high refrigerating speed, etc.; moreover, the glass bottle in the refrigerating chamber can be prevented from breaking.
Description
The utility model relates to a kind of two-temperature freezer or two temperature showcase, especially a kind of two-temperature freezer (or showcase) that thermostat is set in refrigerating chamber.
Mostly the two-temperature freezer of existing two chambers (or showcase) refrigeration system is a system.Because it is different that two room temperatures require, and is not higher than-18 ℃ (the refrigerated display case temperature is not higher than-12 ℃) by the standard code freezer temperature.Generally speaking, the temperature of refrigerating chamber can satisfy the afore mentioned rules requirement, and this room temperature is low more good more; Temperature of refrigerating chamber then requires in 0 10 ℃ scope (the showcase temperature of refrigerating chamber is 6-6 ℃) usually.Because influenced by the adjustment of product structure pattern, refrigeration system and the lack of uniformity of environment for use temperature fluctuation and unlatching door frequency etc., the design difficulty that makes it its refrigerating chamber refrigerating capacity can satisfy the said temperature requirement.If desire to remain enough low temperature, bigger refrigerating capacity must be arranged at the frequent temperature of refrigerating chamber of opening door and barter amount bigger high temperature daytime; And by the two-temperature freezer of this requirement design, at temperature lower night, because of article stop exchange, door does not does not open and close, and the temperature actual measurement of its refrigerating chamber (especially four jiaos of places, bottom) drops to below-10 ℃, vial article such as beer occur because of icing breakage.Otherwise,, and do not reach the temperature requirement of refrigeration in occasions such as daytimes in summer then because of the deficiency of refrigerating chamber refrigerating capacity.
The purpose of this utility model provides a kind of simple in structure, and refrigerating capacity is bigger, and is easy to use, safe and reliable, and the scope of application is wider, and can effectively prevent the low excessively two-temperature freezer of temperature of refrigerating chamber (or showcase).
Major scheme of the present utility model is: be provided with the heater that is subjected to temperature controller control in the bottom of the refrigerating chamber of two-temperature freezer (or showcase).Wherein said temperature controller can be mercury formula temperature sensor, the temperature sensor or the temperature controller of thermistor and various semiconductor thereof, transistor-like; The temperature control point of described temperature controller can be a stepless adjustment type, also can fix, or have the level; Described electricity heating device can be various heating wires (silk), resistance heater (sheet); The position of its setting is generally in the bottom of refrigerating chamber, and especially place, base angle, four limits also can be arranged on the Lower Half wall of refrigerating chamber certainly as required.Consider the convenience of selection or technology, can adopt the line style heating wire to be close on the surface of refrigerating chamber bottom inner bag, and be flat shapes such as " mouth " word or " recessed " word line " day " word and arrange, its watt level can be selected according to refrigerator amount of capacity and instructions for use, is generally 50 100 watts.
Fig. 1 is that cuing open of a kind of refrigerating box of the present utility model shown structural representation.
Fig. 2 is a kind of electrical heating control circuit schematic diagram.
Fig. 3 is a kind of structural representation of electric heating wire.
To the utility model shown in the accompanying drawing 3, can adopt the structure and the design parameter of existing two-temperature freezer referring to accompanying drawing 1 substantially, only on the inner surface of refrigerating chamber (1) bottom inner bag (3), be close to by " mouth " font heating wire (2) is set; Described electric heating linear system adopts the heating wire (2c) of 20 50W/ rice, coats glass fibre (2d), more resistant to elevated temperatures silastic-layer (2b) and aluminum pipe protective sleeve (2a) successively outside it, to reach profit safe, durable, that technology is easier.After then the surface of the aluminum pipe protective sleeve (2a) of heating wire (2) and courage (3) being adhesively fixed, pull out lead-out wire, make foam box layer (5) and get final product.
When assembling, press the circuit shown in the accompanying drawing 2, the temperature controller of forming by temperature-sensing probe, expand with heat and contract with cold air bag or bellows and continuous electrical contact in the arrangement (8).When normal operating conditions, temperature controller does not reach operating temperature, and moving together contact is failure to actuate, and electric heater (2) cuts off the power supply, do not work; Be lower than the temperature that sets (for example-2.0 ℃) temperature sensor and detect signal when the temperature of refrigerating chamber (1) drops to gradually, closed circuit, electric heater (2) work makes the temperature inside the box refoulement liter; During to uniform temperature, automatic shutdown circuit stops to heat.
Therefore, the utlity model has simple in structure, make easy to usely, safe and reliable, Application Range is wide, characteristics such as refrigeration speed, and can effectively control the temperature of refrigerating chamber, thereby avoided Yin Wendu to cross low and cause the ice of glass bottle article etc. to decrease.
Claims (3)
1, a kind of two-temperature freezer of refrigerating chamber band thermostat is characterized in that being provided with in the bottom of described refrigerating chamber (1) electric heater (2) that is subjected to temperature controller (8) control.
2, the two-temperature freezer of refrigerating chamber band thermostat as claimed in claim 1, it is characterized in that described heater (2) is to adopt heating wire to be close on the surface of refrigerating chamber bottom inner bag (3), and the flat shape that is " mouth " word, " recessed " word or " day " word arranges that its electrical power is 50 100 watts.
3, the two-temperature freezer of refrigerating chamber band thermostat as claimed in claim 1 or 2 is characterized in that described heating wire (2) is to constitute by coating silastic-layer (2b) and aluminum pipe protective sleeve (2a) outside the heating wire (2c) successively.
