Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is designed for use by customers in hotels, etc., which is equipped with an inner door having a see-through window for seeing through the stored items. This relates to a room refrigerator.

0002

[Conventional technology]

Conventionally, this type of refrigerator blows cold air from the top forward into the refrigerator body. In addition to forming a cold air passageway for inhaling cold air from the An inner door with a see-through window, and an outer door that opens and closes the retrieval port for stored items on the front side of this inner door. It is known that it has the following.

0003

[Problem that the idea aims to solve]

When removing items from the refrigerator, open the outer door and open the inner door. Check the stored items through the viewing window, and if the desired stored item is there, open this inner door and open the storage area. Take it out. However, when taking out such stored items, that is, when opening the outer door, Because outside air enters the interior and the moisture contained in the outside air adheres to the front of the see-through window, the see-through window This caused condensation and freezing.

0004 The purpose of this invention is to solve the above-mentioned conventional problems by preventing dew condensation on the see-through window when the outer door is opened. The objective is to provide a refrigerator that can prevent freezing.

[0005]

[Means to solve the problem]

In order to solve the above problem, this invention blows cold air forward from the top into the refrigerator body. It forms a cold air passage that is taken in from the bottom, and is housed on the front side of the refrigerator body. An inner door with a see-through window for objects, and an outer door that opens and closes a retrieval port for stored objects on the front side of the inner door. In a refrigerator equipped with A ventilation gap communicating with the penetration part is provided between the inner door and the outer door, and the outer door The back side of the outer door regulates the ventilation above and below the ventilation gap when the outer door is closed, and prevents the outer door from opening. The device is characterized in that a regulating member is provided that releases the ventilation regulation in the open state.

[0006]

[Effect]

According to the present invention, when the outer door is closed, the regulating member prevents the ventilation above and below the ventilation gap. This prevents the cold air circulating inside the refrigerator from flowing through this ventilation gap. Instead, it circulates to the inside of the inner door, that is, to the side of the stored items, and cools the stored items.

[0007] On the other hand, when the outer door is opened, the ventilation restriction of the ventilation gap by the restriction member is released. As a result, some of the cold air inside the refrigerator flows through the ventilation gap through the penetration part, and is distributed in front of the transparent window of the inner door. An air curtain is formed on the surface side. This allows this air curtain to pass through outside air. This prevents contact with the viewing window and prevents moisture from outside air from adhering to the viewing window.

[0008]

【Example】

Figures 1 and 2 show an embodiment of the refrigerator according to the present invention, and Figure 1 shows the refrigerator. A sectional view showing the inside of the refrigerator, and FIG. 2 is a front view of the refrigerator.

[0009] In the figure, reference numeral 1 denotes a refrigerator main body having an outlet 2 for taking out stored items on the front side. this refrigerator The main body 1 has a heat insulating structure by filling a heat insulating material 5 between an outer box 3 and an inner box 4. Ma In addition, a partition is provided at the rear and upper part of the refrigerator body 1 with a predetermined gap from the inner box 4. An evaporator 7 and a blower 8 are installed in this gap to lower the air inside the refrigerator. A cold air passage 9 is formed in which cold air is taken in from the bottom and cool air is blown out from the top. Also, this refrigerated Inside the storage body 1, shelves 10 are arranged in four levels above and below, on which various stored items (not shown) are placed. It is.

0010 On the front side of the refrigerator main body 1 configured in this way, there are an inner door 11 and an outer door 12 at the front and rear. Each is installed. This inner door 11 faces the stored items placed on each shelf 10. A see-through window 13 is provided so that the stored items can be visually recognized from each see-through window 13. It has become. Further, the inner door 11 is arranged with a gap between the upper and lower sides of the inner box 4, This gap constitutes a penetration part 14 that communicates the inside of the refrigerator with the back side of the outer door 12. Ru. On the other hand, the outer door 12 opens and closes the outlet 2, and is arranged with a gap from the inner door 11. This gap constitutes a ventilation gap 15 that communicates with the upper and lower penetration parts 14. Ru. Additionally, airtight packings 16 are attached to the upper and lower sides of the back surface of this outer door 12. In addition, there is a ventilation gap 15 near the top that contacts the see-through window 13 when the outer door 12 is closed. A regulation packing 17 for regulating ventilation is attached which partitions into upper and lower parts.

[0011] According to this embodiment, when the outer door 12 is closed, the regulation packing 17 is placed between the ventilation holes. In order to restrict the ventilation above and below the gap 15, the cold air circulating inside the refrigerator body 1 is As shown by the dashed-dotted arrow, the inner door 11 does not flow through the ventilation gap 15. It circulates to the inside, that is, to the side of the stored items, and cools the stored items.

0012 On the other hand, when the outer door 12 is opened (double-dashed line in Fig. 1), the regulation gasket 17 Since the ventilation restriction in the ventilation gap 15 is lifted, some of the cold air inside the refrigerator is As shown by the line arrow, the air flows through the ventilation gap 15 through the penetration part 14, and the transparent part of the inner door 11 An air curtain is formed in front of the viewing window 13. This allows this air curtain to prevents outside air from contacting the transparent window 13 and prevents moisture from the outside air from adhering to the transparent window 13. There is no.

[0013]

[Effect of the idea]

As explained above, when the outer door is closed, all the cold air circulates to the stored items. In addition to cooling the contents inside the refrigerator, when the outer door is opened, a portion of the cold air inside the refrigerator is released. The air flows through the ventilation gap through the penetration part, and an air curtain is placed in front of the transparent window of the inner door. Therefore, condensation and freezing on the front surface of the viewing window can be prevented.
