Description

[Detailed description of the invention] This invention relates to an improvement of a refrigerator that is equipped with an evaporator and a main blower inside the freezer body to forcefully circulate and cool the freezer compartment and the refrigerator compartment. The purpose is to shorten the freezing time of food and reduce the number of man-hours required to install parts.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is a refrigerator main body, and 5 is a bottom plate of the freezer compartment 3. A partitioning member 2 is provided in the main body 1 to form a freezing compartment 3 and a refrigerating compartment 4 above and below.

The partition member 2 is equipped with an evaporator 6 and a main blower 7,
A cooling compartment A is formed.

Reference numeral 8 denotes a heat insulating material that reduces the degree of heat influence exerted by the high-temperature air in the cooling compartment A on the freezer compartment 3 during defrosting.

A ventilation duct 9 is provided at the rear of the cooling compartment A to communicate the freezing compartment 3 and the refrigerator compartment 4, and the cooling air from the cooling compartment A is distributed between the two sides by the main blower 7 as shown by the solid line arrows in FIG. Forced ventilation is applied to the rooms 3 and 4 to cool both the rooms 3 and 4.

10 is an auxiliary blower. 11 and 12 are respectively freezer compartments 3.
This is an air outlet that opens into the refrigerator compartment 4.

The auxiliary blower 10 is installed in the ventilation duct 9 between the main blower 7 and the freezer compartment ventilation port 11, and the front side of the auxiliary blower 10 is provided with an auxiliary blower for blowing cold air into the freezer compartment 3 when the auxiliary blower 10 rotates. A discharge port 13 is provided.

As shown in FIG. 4, the bottom plate 5 of the freezer compartment is provided with a suction port 14 for sucking cold air forcedly circulated through the freezer compartment 3 into the cooling compartment A.
In addition, the auxiliary discharge port 13 is formed to have a larger opening at the bottom, and the fan ring 15 of the auxiliary blower 10 is integrally molded.

Further, a fan ring 15 is attached so as to protrude into the ventilation duct 9, and the amount of air blown into the freezer compartment 3 by the main blower 7 is regulated by the fan ring 15.

Reference numeral 16 denotes a freezing switch for manually operating the auxiliary blower 10 for an arbitrary period of time when rapidly freezing food.

Next, the cooling state when rapidly freezing food will be explained with reference to FIG. 3.

The food 17 that has not yet been frozen is placed on the bottom plate 5 of the freezer compartment, the quick-freeze switch is manually operated, and the auxiliary blower 10 is operated.

When the auxiliary blower 10 is operated, the cooling air in the cooling compartment A is first sent into the ventilation duct 9 by the blower 7, as shown by the solid arrow in FIG.

To cool the refrigerator compartment 4, as in the case of normal cooling, cooling air is discharged from the freezer compartment ventilation port 2, circulates within the refrigerator, and is then sucked into the cooling compartment A through the suction port 18, where it is cooled to an arbitrary temperature. .

On the other hand, to cool the freezer compartment 3, the main blower 7 sends cooling air into the ventilation duct 9, and the auxiliary blower 10 sucks in cold air from the freezer compartment 3 through the freezer air outlet 11, and then draws high-speed cold air through the auxiliary outlet 13. The food 17 is discharged into the freezer compartment 3 as
Cool quickly.

At this time, most of the high-speed cold air discharged is discharged to the lower part of the quick-freezing chamber 3 because the opening shape of the auxiliary discharge port is larger at the bottom as shown in Fig. The air outlet 11 not only efficiently blows high-speed cold air directly onto the surface of the
Most of the cold air sucked into the food 17 can be sucked in after cooling without short circuiting.

In the cold air circulating in the freezer compartment 3, the freezer compartment 3 during normal operation
Cold air equivalent to the cooling air that had been discharged into the cooling compartment A is drawn into the cooling compartment A from the suction port 14, but all other circulating cold air is sucked in from the freezer compartment ventilation port 11, and is then removed from the cooling compartment A in the ventilation duct 9. It is mixed with the cooling air sent in by the main blower 7, and forcedly circulated again as relatively low-temperature, high-speed cold air to the freezer compartment 3 by the auxiliary blower 10, rapidly lowering the temperature of the food 17.

Note that the fan ring 15 of the auxiliary blower 10 protrudes into the ventilation duct 9, and by changing the length of this protrusion, the cooling air in the cooling compartment A discharged into the freezer compartment 3 and the cold air in the freezer compartment 3 can be The mixing ratio of can be changed arbitrarily.

That is, by increasing the protrusion margin, the amount of cold air mixed in the compartment A can be reduced, and conversely, by decreasing the protrusion margin, the amount of cold air mixed can be increased.

Then, when the time has passed when the temperature of the food 17 is thought to have decreased to a predetermined temperature after rapid freezing, the freezing switch 16 is manually turned OFF, the operation of the auxiliary blower 10 is stopped, and the food 17 is It is then moved to a suitable freezer compartment 4 for storage and returned to the normal cooling state.

As described above, the auxiliary blower 1 protrudes into the ventilation duct 9.
The fan ring 15 of 0 regulates the amount of ventilation to the freezer compartment 3 during normal operation, and the auxiliary blower 10 controls the amount of air flowing into the freezer compartment 3 during normal operation.
The mixing ratio of the high-speed cold air discharged into the freezing compartment 3, that is, the cooling air of the cooling compartment A and the air inside the freezing compartment 3, is regulated, and the opening shape of the auxiliary discharge port 13 is set so that the lower part is wider. In addition to being open, since it is integrally formed with the bottom plate 5 of the freezer compartment, during quick freezing, the influence of temperature on the inside of the refrigerator compartment 4 is reduced, the cold air in the freezer compartment 3 is efficiently circulated, and the freezing time of food can be shortened. , the number of man-hours required for attaching parts can be reduced.

In addition, in the embodiment, the inside of the refrigerator is divided into the freezing compartment 3 and the refrigerating compartment 4, but the structure is not limited to this, and the configuration is not limited to this, and the configuration is such that two compartments are provided, and one compartment is provided with an auxiliary blower 10, thereby requiring quick freezing or refrigeration. If so, it can be applied.

As is clear from the above embodiments, the refrigerator of the present invention is provided with an evaporator and a main blower in the refrigerator main body, and is cooled by a partition wall that partitions the main body into a freezing compartment and a refrigerator compartment, and the evaporator. ducts for guiding the frozen air to the freezer compartment and the refrigerator, and further equipped with a fan ring opening into the freezer compartment, and an auxiliary blower for forcibly blowing cold air from the duct communicating with the freezer compartment to the freezer compartment. Also, the auxiliary blower can cool down the freezer compartment more quickly and at a lower temperature.

Further, by providing a fan ring in the duct, the cold air from the evaporator and the cold air in the freezer compartment are mixed, so the circulation of the cold air is improved.

Furthermore, by forming the fan ring integrally with the bottom wall of the freezer compartment, the number of products can be reduced.

Furthermore, by partitioning the opening of the fan ring so that the lower part is wider than the upper part, a large amount of cold air from the evaporator can be discharged, and good cooling can be performed.
