Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a refrigerator, and in particular to a refrigerator with improved cooling power.
Regarding storage.

[Conventional technology]

A conventional refrigerator is shown in FIG. 5. In this type of refrigerator 1, a discharge cold air passage 13 to the refrigerator compartment is provided at one end of the cooler 8 of the cooler compartment 7 installed at the back of the cold 1 east compartment. It has a structure in which a part of the cold air from the cooler conduit 7 is directed by a blower through a space formed by a cooler cover 10 and a fan guard 11 into a discharge cold air passage. 5
6 is a freezer compartment return passage for returning cold air to the cooler compartment 7, and 6 is a refrigerator 1 return passage for returning cold air to the refrigerator compartment.

Regarding this type of refrigerator, the Special Publication No. 60-3322
Examples include No. 4.

[Problem that the invention seeks to solve]

In the above conventional technology, a part of the cold air from the cooler room is passed through the space between the cooler cover and the fan guard using a blower.
When reaching the entrance of the cold air discharge passageway to the refrigerator compartment, the flow direction of the cold air is bent and twisted, which increases ventilation resistance in this area and may reduce the cooling power.

An object of the present invention is to provide a refrigerator in which the cooling power is improved by reducing the ventilation resistance of the cold air discharge passage.

[Means for solving problems]

The above purpose is achieved by the space between the cooler installed at the back of the freezer compartment, the cooler cover installed in the front of the cooler, the fan guard installed in the front of the cover, and the cover and fan guard. This is accomplished by arranging a cold air discharge passageway for the refrigerator compartment, and an entrance portion of the cold air discharge passageway for the refrigerator compartment being located directly below the space.

[Effect]

The cold air from the cooler is discharged into the space formed by the cooler cover and the fan guard, and when the cold air is delivered to the entrance of the cold air discharge path to the refrigerator compartment, the cold air is
By installing the entrance of the cold air discharge passage to ft&'A directly below the space formed by the cooler cover and fan guard, cold air flows through without resistance, improving cooling power performance. It is possible to improve the

In addition, by installing the entrance of the cold air discharge passage to the refrigerator compartment in the space formed by the cooler cover and fan guard, the width of the cooler can be made approximately the same as the inside dimension of the freezer compartment. By increasing the size, the cooling power performance can be further improved.

[Example] □ An example of the present invention will be described below with reference to FIGS. 1 to 4. ■ is the refrigerator itself, compartment! i! 2, it is divided into a freezer compartment 3 in the upper part and a cold & cold compartment 4 in the upper part. A freezer compartment return passage 5 and a refrigerator compartment return passage 6 are formed in the partition wall 2 for returning cold air in the freezing compartment 3 to a cooler compartment, which will be described later. Reference numeral 7 denotes a cooler chamber installed on the back wall of the freezer compartment, and has a cooler 8 inside. The cooler 8 has a width that is approximately the same as the inside dimension of the freezer compartment 3. Reference numeral 9 denotes a blower that forcibly circulates cold air in the cooler chamber 7 into the freezer compartment 3 and the refrigerator compartment 4, and has a fan 9a and is installed above the cooler 8.

IO is a cooler cover that forms the cooler chamber 7 and covers the cooler 8, and is provided with a mouth ring for the fan 9a of the air blower [9]. 11 is a fan guard.

The cooler cover l is spaced apart from the previous cooler cover lO.
It is installed in front of the cold air ventilation grill lla.
is provided. 12 is a fan 9 whose upper end is a blower 9;
A cold air guide plate located near the cooler cover IO1 or the cold air guide plate whose lower end extends to the vicinity of the entrance of the cold air discharge passage, which will be described later, partitions the space formed by the cooler cover 10 and the fan guard 11. , which is integrally molded with the fan guard 11. Reference numeral 13 denotes a cold air discharge passage for discharging a portion of the cold air discharged by the blower 9 from the cooler chamber 7 into the refrigerator compartment 4, which is necessary for cooling the inside of the refrigerator compartment 4. It is formed by locating the entrance part 13a of the cold air discharge passage 13 into the refrigerator compartment 4 at one end directly below the space formed by the cooler cover lO and the fan guard 11. It is something that 14 is the cold air discharge passage 1
This is a cold air amount adjustment damper that adjusts the amount of cold air discharged into the cold JiIlc chamber 4 through the cold storage chamber 4, and is installed at the outlet 13b of the cold air discharge passage 13 on the back ceiling of the refrigerator chamber 4. The cold air circulation path of the refrigerator configured in this way is such that, as shown by the arrow in the figure, the cold air cooled in the cooler chamber 7 is passed through the fan 9a of the blower 9, and some of it is passed through the cold air ventilation grill lla of the fan guard 11. It is discharged into the freezer compartment 3 and cools the interior of the freezer compartment 3 to a predetermined temperature. Also,
The cold air introduced into the freezer compartment 3 passes through a freezer compartment return passage 5 provided in the partition wall 2 and returns to the cooler compartment 7 . On the other hand, a part of the cold air discharged by the fan 9a of the blower 9 is transferred to the cooler cover lO and the fan guard l.
The cold air passes through the space in the interior of the room, enters the cold air discharge passage 13, enters the refrigerator compartment 4, and cools the inside of the refrigerator compartment 4. The cold air amount adjusting damper 14 controls the cold air to be delivered to a predetermined level within the refrigerator compartment 4. The temperature is controlled at Further, the cold air introduced into the refrigerator compartment 4 returns to the cooler compartment 7 through a refrigerator compartment return passage 6 provided in the partition wall 2.

According to this embodiment, when sending cold air into the refrigerator compartment 4, a part of the cold air is sent to the cooler cover 10 and the fan guard 11 by the blower II kg fan 9a.
Since the cold air is smoothly guided through the inner space to the entrance of the cold air discharge passage 13 provided directly below the space, there is no increase in ventilation resistance at this time. In addition, by configuring the cold air passage in this way, the width of the cooler 8 can be made approximately the same as the inside dimension of the freezer compartment 3. Since it can be easily made thicker, the cooling power performance can be further improved accordingly.

〔Effect of the invention〕

According to the present invention, when the cold air from the cooler room is transferred to the refrigerator by the blower plate, the entrance of the cold air discharge passage to the refrigerator is located directly in the space between the cooler cover and the fan guard. Since it is located in the opposite direction, there is less ventilation resistance to the flow of cold air, and the cold air is distributed smoothly. This has the effect of improving cooling power performance.
