Abstract

The present invention relates to a refrigerator having a separate refrigeration compartment for preventing odor transfer. The refrigerator is separated from a single refrigeration chamber that is generally used and two refrigeration chambers are provided. When the two coolers on the refrigeration cycle circulate the refrigerant repeatedly with one compressor to proceed with the cooling operation, each cooler is operated by the control signal of the temperature sensor detected in each of the separate refrigerating chambers. Foodstuffs that have a stimulating odor are related to a refrigerator which effectively prevents odor transfer by allowing convection of internal air to occur only in a refrigerating chamber provided separately.

Description

Refrigerator with refrigerator to prevent odor transfer

The present invention relates to a refrigerator equipped with a refrigerator for preventing odor transfer of a refrigerator, and a non-irritating food without an odor transfer simultaneously with a foodstuff that transmits irritating odors such as kimchi to one commonly used refrigerator compartment at the same time in one refrigerator compartment. It is structurally improved to have an appropriate ratio of size and separated into two refrigerating chambers so that foods that transmit these irritating odors and non-irritating foods without smell transfer can be stored separately. It relates to a refrigerator provided.

Conventionally, as shown in FIG. 1, one refrigerator compartment (R) is provided, and the shelf 10 is inserted into the inside of the interior compartment so that the compartment can accommodate food, and other food and beverage in the inner pocket of the door. Are configured to be stored.

In the case of the conventional refrigerator including one refrigerator compartment, the coolant circulates along the freezing cycle and generates cold cold air by heat exchange between the surface of the cooler (not shown) provided in the main cold air duct and the surrounding air. Through a series of processes to supply cold air into the refrigerators of the freezer compartment (F) and the refrigerating compartment (R) by means of a blower fan installed in the refrigerator, food and beverages stored in each compartment are kept longer and fresher.

The cold air supplied through this process, in particular, the temperature rises to a considerable extent while circulating in the refrigerator compartment R, for example, when it is supplied to the refrigerator compartment R and the freezer compartment F at about -19 ° C. Since the refrigerating chamber (R) is circulated and the temperature is raised to about 1 ° C. to 6 ° C., the refrigerating cycle of reducing the temperature again and re-supplying the reheated cold air is repeated.

Of course, even in the case of the freezing chamber (F), the cold air which is slightly elevated in temperature while circulating in the refrigerator is returned to the main cold air duct along with the cold air of which the temperature is increased in the refrigerating chamber (R).

However, since the cold air circulated and supplied in this way is returned with foods that transfer the irritating odor while circulating the inside of the refrigerating chamber R, for example, kimchi and the like, the odor is transmitted. When food and the like are stored for a longer time, not only the inside of the refrigerator freezer (F) and the refrigerating chamber (R) but also other foods stored in the odor is transferred to cause the overall odor.

In addition, in order to eliminate this problem, the deodorant is attached to the flow path where cold air is returned or supplied, but this is only a temporary solution and is not a fundamental solution. Although it is stored, it is also cumbersome to wrap one by one, and ultimately it was impossible to remove the bad smell.

The present invention has been devised to solve the above problems in consideration of the above-mentioned problems, and among the foods stored in the refrigerator, the refrigerator keeps only the foods that transmit irritating odors and the non-irritating foods without odor transfer. There is a technical problem to provide a refrigerator provided with a refrigeration chamber for preventing odor transfer to provide a separate refrigeration chamber to separate and store these stored foods.

77: temperature sensor 80: the second refrigerator compartment

In order to realize the above problems, the first refrigerator compartment and the second refrigerator compartment formed by separating the refrigerator compartment of the conventional refrigerator in an appropriate ratio size, and the first refrigerator compartment has a temperature sensor for sensing the temperature inside the In this case, a separate cooler is provided to allow the supply of cold air through a signal sensed by the temperature sensor.

Hereinafter, it will be described in more detail on the basis of a preferred embodiment of the present invention.

FIG. 2 is a schematic front view showing a state in which a separate first refrigerator compartment 60 can be stored along foods that transmit irritating odors according to the present invention, and the first refrigerator compartment 60 and the second refrigerator compartment ( The ratio of the size of 80) can be variously modified according to the model produced, and can also be configured as a partition type that can be changed to meet the needs of consumers.

In addition, the interior of the first refrigerator compartment 60, the shelf 10, which can be accommodated in the same compartment as the second refrigerator compartment 80 is installed, but the width between each shelf 10 to be adjustable and the second refrigerator compartment (80) The vegetable compartment 20 provided in the) will be omitted in the first refrigerator compartment (60).

3 is a schematic cross-sectional view of the above-described FIG. 2 schematically showing the configuration of the present invention.

As can be seen from the figure, a cooler capable of calculating the cool air of a predetermined capacity by forming the main duct 90 at the upper end of the first refrigerating chamber 60 of the appropriate size formed separately, for example, at the lower end engaged with the trimming section 40. (64) is installed and the rear side of the blower fan (66) is to be configured so that the cold air can be supplied to the interior through the cold air discharge port 70 in the main duct (90).

In addition, when the supplied cold air rises while circulating inside the refrigerator, the cooler 64 of the main duct 90 rides through the cold air return hole 72 formed at the upper side of the first refrigerating chamber 60 as it is returned to the conventional trimming plate. It is configured to repeat the supply return while returning to the surroundings and changing to a lower temperature cold with the operation of the cooler 64 again.

Here, the return cold air and the supply cold air are separated by the blocking plate 68, and the cold air having such a temperature difference coexists in the main duct 90.

In addition, the temperature sensor (77) is attached to the place in the first refrigerator compartment 60, the cold air circulating in the inside of the temperature rises as the temperature rises outside the range of the initially set value by transmitting a signal to the controller to operate the cooler ( The cooling action of 64) is to occur.

Of course, the configuration of the second refrigerating chamber 80 is the same as the conventional one, the cooling operation of the cooler (not shown) is also the same.

That is, two coolers may be operated at the same time with one compressor, only one may be operated, and defrosting is performed as in the conventional cooling cycle.
