Description

[Detailed description of the invention] This invention is a freezer that divides the inside of the main body into two upper and lower compartments by cooling compartments, and cools the compartments by forcing cold air into the compartments. This relates to a multi-building device that aims to shorten the time.

To explain the conventional auxiliary blower type multi-building device with reference to Figs. 1 and 2, 1 is a freezer main body, and a partitioning member 2 is provided inside the main body 1 to form a multi-building room 3 and a freezing room 4 above and below. are doing.

The partition member 2 is formed with a cooling partition A in which a finned evaporator 5 and a main blower 6 are housed.

A ventilation duct 7 is installed at the rear of the cooling compartment A, and communicates with the duct outlet ports 8 and 9 of the multi-building compartment 3 and the freezing compartment 4.

Reference numeral 10 denotes a control plate that protrudes into the ventilation duct 7 and controls the amount of ventilation to the multi-building room 3.

The upper and lower chambers 3 and 4 are cooled to a predetermined temperature by the flow of cold air as shown by the arrows in FIG.

That is, the low-temperature cold air in the cooling compartment A is sent into the ventilation duct 7 by the main blower 6, and is sent to the upper and lower compartment duct discharge ports 8.
, 9 into both chambers 3 and 4, and circulates within both chambers 3 and 4 for cooling.

Then, the cooling air passes through the suction ports 12 and 13 of each chamber, returns to the cooling compartment A again, repeats the circulation process, and returns to both chambers 3 and 3.
, 4 to a predetermined temperature.

Reference numeral 11 denotes an auxiliary blower, which is installed in front of the multi-building room duct outlet 8. When the quick switch 14 is turned on during rapid freezing, the auxiliary blower 11 rotates, and the ventilation is passed from the cooling compartment A to the multi-building room 3. By increasing the amount, the freezing time of the food 17 in the multi-building room 3 is accelerated.

However, when the conventional multi-building device freezes rapidly,
In order to increase the amount of cold air ventilated into the multi-building room 3 by the auxiliary blower 11, the ventilation ratio between the multi-building room 3 and the freezer compartment 4 is changed, and the absolute ventilation amount in the cooling compartment room A is increased. .

Therefore, when rapidly freezing particularly high-temperature foods, the temperature of the low-temperature cold air in cooling compartment A is rapidly increased, and as a result,
There was a drawback that the temperature inside the freezer compartment 4 increased.

Further, since the auxiliary fan 11 is installed within the multi-building room 3, there is a drawback that the effective internal volume within the multi-building room 3 is reduced.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional products, allows food in the multi-building compartment to be quickly frozen without reducing the cooling capacity of the freezer compartment 4 during quick freezing, and increases the effective internal volume. .

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

Note that the same reference numerals indicate the same parts. In Fig. 3 and Fig. 4, 2 is a partitioning member, with a continuous room 3 and a freezing room 4 above and below.
is formed.

The partition member 2 is formed with a cooling compartment A in which a finned evaporator 5 and a main blower 6 are installed, and a duct outlet 8 for the multi-building compartment 3 and the freezing compartment 5 is formed at the rear of the cooling compartment A. , 9 is provided.

Reference numeral 11 denotes an auxiliary blower, which is provided in the ventilation duct 7 between the cooling compartment A and the multi-building room duct outlet 8.

15 is a fan ring for an auxiliary blower, and controls the amount of ventilation to the multi-building room 3 by protruding into the ventilation duct 7.

Note that the auxiliary blower 11 may be either a turbo type or a sirocco type.

During normal cooling, cold air is circulated as indicated by the arrows in FIG. 3 to cool both the upper and lower chambers 3 and 4 to a predetermined temperature.

Further, during rapid freezing, the auxiliary blower 11 is rotated by turning on the quick switch 14 to circulate cold air as indicated by the arrows in FIG. 4.

That is, the low-temperature cold air in the cooling compartment A is sent to the ventilation duct 7 by the main blower 6, and the ventilation ratio to the multi-building room 3 and the freezing room 4 is controlled by the auxiliary blower fan ring 15.
The low-temperature cold air sent to the freezer compartment is discharged from the duct outlet 9, cools the freezer compartment 4, and returns to the cooling compartment A through the suction port 13.

On the other hand, the low-temperature cold air sent to the multi-building room 3 side is discharged at high wind speed into the multi-building room 3 from the auxiliary discharge port 16 along with the multi-building room cool air sucked in from the multi-building room duct discharge port 8 by the auxiliary blower 11. The food 17 is quickly frozen.

Of the cold air that has cooled the food, only the amount of ventilation that is controlled by the auxiliary fan ring 15 and the same amount as the low-temperature cold air discharged into the multi-building room 3, that is, the amount of ventilation that does not reduce the cooling effect to the freezer compartment 4, is controlled by the auxiliary fan ring 15. , returns to the cooling compartment A through the suction port 12, and the others are sucked in through the multi-building room duct 8, and are returned to the auxiliary blower 1.
1, the air is mixed with the low-temperature cold air sent from the cooling compartment 4, and is discharged into the multi-building room 3 as cold air with a relatively high temperature but with high wind speed and volume.

Therefore, by using the ventilation duct 7 as a bypass circulation path, it is possible not only to increase the air volume without changing the static pressure inside the freezer, but also to cool the freezer compartment even when rapidly freezing relatively high-temperature foods. Practically necessary rapid freezing is possible without reducing effectiveness.

As is clear from the above embodiments, the freezer of the present invention is divided into a continuous compartment and a freezing compartment by a cooling compartment, and a main blower forcibly circulates low-temperature cold air from the cooling compartment to the compartment for cooling. An auxiliary blower is installed in the ventilation duct between the cooling compartment and the multi-building room duct outlet, and a fan ring for the auxiliary blower protrudes into the ventilation duct to control the amount of cold air flowing into the multi-building room. The auxiliary blower is rotated to discharge low-temperature cold air in the cooling compartment to the multi-building room, and at the same time, the cold air in the multi-building room is sucked in from the multi-building room duct outlet and forcedly circulated within the multi-building room, bypassing the ventilation duct. It is used as a road.

Therefore, without reducing the cooling efficiency in the freezer,
It has great practical value as it enables rapid freezing and increases the effective internal volume within the multi-building room.
