Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Application The present invention relates to a refrigerated showcase for face-to-face sales, and relates to an improved structure of an upper lid body that improves the display effect for both customers and sales staff.

Conventional Technology Publication of Utility Model Publication No. 56-5987 discloses a case in which a see-through door storage section, a door body, and a lid body having an opening are arranged on the top of a refrigerating showcase whose main body is composed of a heat insulating wall with an opening on the top. There is a face-to-face sales type frozen showcase (so-called dipping showcase) as typified by the official gazette. The lid body of this showcase includes left and right side walls, a front glass,
The main body is made up of a top glass, a fluorescent light, and a shade.A door storage section is formed in the lower half of the top glass, and an opening for entering and exiting products is formed in the rear half.This opening can be opened and closed freely. The door body is slidably closed and can be stored in the door storage section when the door is opened.

Problems to be Solved by the Invention According to the above-mentioned showcase, when the inside of the storage is viewed through the front glass in a state where the door body is stored in the door storage part formed in the lower half of the top glass, the front of the door body is Since the door is located approximately midway between the front glass and the upper surface of the inside of the refrigerator, the work space for seeing through and selling is narrowed, making it difficult to perform sales operations. There was a problem that it was difficult to check the products inside. In addition, many of them have heat ray reflective films attached to the inner surface of the front glass and the lower surface of the flat transparent body of the door body.
When two pieces of glass (the front glass and the glass part of the door body) to which this film is attached overlap, there is a problem in that the transparency deteriorates and it becomes impossible to check the color of the products inside the refrigerator.

Therefore, the present invention has developed a refrigeration system R configured to ensure transparency through the front glass regardless of the opening/closing operation of the door body.
- Its task is to provide a case.

[Structure of the invention]

Means for Solving the Problems The present invention provides a refrigeration showcase configured to solve the above problems, which includes a transparent section having a front transparent plate and an upper transparent plate, and a transparent section below the upper transparent plate. A storage room with an open top is equipped with a lighting section, an opening for entering and exiting products located behind the transparent section, and a transparent door that is held openable and closed by a sliding rail and closes the opening. A transparent door is provided at the top of the heat insulating box body, and when the lid is fully open, it is below the illumination part and close to the top transparent plate, and the front part is close to the top of the front transparent plate. I was able to store it and keep it.

In addition to holding the transparent door open and closed, the working sliding rail also
It functions to hold and fix the transparent door in a fully open state at a position below the lighting section that does not obstruct the view when looking into the storage room from the front transparent plate, and the field of view from the front transparent plate depends on the opening and closing operation of the transparent door. Moreover, the space below the lid body is not narrowed too much when the transparent door is fully opened.

Example The present invention will be described in detail below based on the drawings.

(1) shown in Figure 2 is a face-to-face refrigerated showcase called a dipping case, which consists of an insulating box body (2) with an open top, and a front transparent plate on the customer side, i.e., the front. A transparent part (5) having a front glass (3) and a top glass (4) as a top transparent plate on the top surface, an opening (6) for putting in and taking out products on the sales side, that is, the back side, and this opening (6) Transparent doors (7) that can be opened and closed are respectively positioned to cover the top opening of the insulation box body (8) and the insulation box body (2). It consists of a machine room (9) which houses and installs a compressor, a condenser, a blower device (all not shown), etc. in the lower part.

(10) is a metal partition plate which is arranged at an appropriate interval from the inner surface of the front and rear walls of the insulation box body (2), has front left and right walls and a bottom wall, and has a U-shaped longitudinal section; A cold air passage (11) is formed on the outer periphery of both front walls of the plate (10) and under the bottom wall, and a plate fin type cooler (12) is provided below the bottom wall.
) and a cooling room equipped with an axial blower (13), etc.
14), the inside of which is filled with frozen desserts such as ice cream or sherbet, and a storage chamber (16) that stores a plurality of containers called bats (hereinafter referred to as bats) (15).
is formed.

A fixing device (17) for orderly and efficiently aligning and fixing a plurality of bats (15) is disposed in the upper part of the storage chamber.

The front wall (IOA) and the back wall (IOB> of the partition plate (10) have a part corresponding to the gap formed between the sides of the bat when the bat (15) is fixed to the fixing device! (17). A first suction port (21) and a first air outlet (22) are formed respectively, and first suction ports (21) are provided at appropriate intervals at a lower position than the first suction port (21) and the first Suita port (22). )
A second suction inlet and a second outlet (both not shown) having a smaller opening area than the first suita port (22) are formed.

The front wall (IOA>outer area of the partition plate (10) is connected to the return path (2)
3) The outer circumferential area of the back wall (IOB) is referred to as a supply path (24), and an air volume adjustment plate (25) that adjusts the flow rate of cold air upward from the first outlet (22) in the supply path (24) is provided. A top air outlet (26) is formed with a horizontal opening so that cold air flows horizontally over the top surface of the bat (15) which is fixed above the air volume adjustment plate (25). ing.

The air volume adjustment plate (25) adjusts the flow rate of cold air blown into the storage room from the first Suita port (22) and second air outlet formed in the back wall (IOB) and the flow rate of cold air blown out from the upper surface air outlet (26). The opening area is set so that the former can be divided at a certain ratio, for example, about 7:3. on the other hand,
A top suction port (27) is formed at the top of the return path (23) to collect the cold air blown out from the top Suita port (26). (28) is a protective glass for preventing the cold air flowing along the top surface of the bat (15) from directly hitting the front glass (3).

A bat (
A storage room (30) is formed for the air blower (15)
) is provided with a heat insulating wall (31) on its upper surface so as not to receive the cold air directly in the axial direction from the cooling chamber (14), and a portion of the cold air leaving the cooling chamber (14) passes through the communication hole (32) to the storage chamber. (30).(33) is the cooling room (14)
This is an elongated branching plate that divides the cold air sent out from the outlet into the supply path (24) and the communication hole (32).

The transparent door (7) in the lid (8) has a sliding rail (40)
sliding bodies such as rollers (41
) is slidably supported. The sliding rail (40) has an inclined part (42) held at the same inclination as the opening (6) on the rear side of the lid, and a lighting device (43) disposed below the rear of the top glass (4). ) is located below the illumination part (44) with a built-in structure, and is held substantially horizontally like the top glass (4), and consists of an inclined part (42) and a continuous horizontal part (45),
A fixing groove (46) into which the sliding body (41A) of the transparent door (7) is inserted is formed at the front end of the horizontal lower surface. However, when the transparent door (7) is moved forward along the sliding rail (40), the sliding body (41A) is dropped into the fixing groove (46) and locked, and the door (7) is held horizontally ( This is the fully open state of the door (7)), and the front end of the door (7) is the front glass (
The front glass (3) and the transparent glass of the transparent door do not overlap so that the field of view when looking into the storage room (16) through the glass (3) is not obstructed. The transparent door (7) has its sliding body (41A) fixed in the fixing groove (4).
It is fixed to the horizontal part (45) by dropping it into the transparent door (7), and when the sliding body (41A) is released from the fixing groove (46), the weight of the transparent door (7) allows it to be fixed to the horizontal part (45). 42
), the sliding body (41B) naturally slides along the horizontal part (45), and the sliding body (41A) naturally slides along the opening (6
) will be automatically closed. In addition, the transparent door (7) gradually increases its closing speed (closing speed) due to the influence of gravity from the time of unlocking to the forward closing state, so it becomes a fully closed state. Instantly, the rear end of the door (the side on which the handle (47) and the backing (48) as an airtight retaining means are arranged) moves with a force proportional to the speed of the rear end of the opening (commonly known as collide with bending over). In order to reduce the impact on the surrounding area and the transparent door (7) due to this collision, a backing (48) is provided that not only maintains airtightness but also functions as a shock absorbing member. Since it does not reduce the closing speed of the door (7), it is likely to cause problems in terms of durability during long-term use. Therefore, a horizontal pressing force is applied to an appropriate place, for example, the lower part of the inclined part (42), so as to press the sliding body (41B) on the rear end side of the door toward the glass from the side surface.
0) Applying frictional force to the sliding body (41) itself to close the door (7)
) A flexible deceleration member, such as a leaf spring (49), is arranged to be included in the orbit of the sliding body (41) (Fig. 3). ~See Figure 5).

In addition, the front glass (3), the top glass (4), the transparent door (7)
) A heat ray reflective film is pasted on the inner surface of each
The heat rays that pass through the lid (8) are reflected to open the storage chamber (16).
) reduces the heat load entering the system.

Therefore, when the transparent door (7) is held and fixed to the horizontal part (45) of the sliding rail (40), the lighting device (43)
The light from the illumination part ft (43) is transmitted, but the heat rays are reflected, which acts to alleviate the thermal influence of the illumination part ft (43).

〔Effect of the invention〕

As described in detail above, according to the present invention, when the transparent door is held in the fully open state, the visibility from the front transparent plate is not obstructed, so that good visibility into the storage room can be achieved. In addition, since the sliding rail is located below the lighting section, the transparent door is positioned below the lighting section when the door is opened, and the heat generated by the illumination of the lighting section is transferred between the top surface of the transparent door and the top surface of the transparent door. It can stay in the space between the back side of the transparent plate,
When opening a transparent door, where the thermal load increases, especially when the door is fully opened, it makes it difficult for the heat associated with the illumination to be transferred to the storage room side, thereby reducing the thermal load. Furthermore, when the transparent door is fully opened, the door is close to the top transparent plate and the front end is stored close to the top of the front transparent plate, so the space below the lid and above the top of the storage chamber is almost narrowed by the door. This eliminates the hassle and makes sales work easier.
