Description

The present invention relates to a so-called case-in-case type open showcase in which a movable case is arranged in a storage chamber.

<B> Conventional Technology The case-in-case type refrigerating / refrigerating showcase described in Japanese Utility Model Publication No. 1-25263 (F25D 17/08) has an evaporator and a first cooling air circulation fan installed outside. A refrigeration / refrigeration showcase in which an inner showcase having a heat exchanger and a second cooling air circulation fan is arranged in the product display space of the showcase, wherein the outer showcase has shelf posts for attaching shelf boards. , The shelf is provided with mounting brackets at a plurality of vertically spaced positions, while the inner showcase is provided with supporting brackets, and the supporting brackets are engaged with the mounting brackets to provide the inner show. A configuration is shown in which the case is detachably attached to the outer showcase.

<C> Problem to be Solved by the Invention According to the above-mentioned conventional technique, an inner showcase accommodating a heat exchanger and a second cool air circulation fan is attached to a shelf for attaching a shelf plate, and the inner show is attached. The weight of the inner showcase is much heavier than the shelves adjacent to each other because not only the items are stored in the case but also the top of the inner showcase is used as a shelf board to place the goods. The combined force cannot support the load of the inner showcase that is suspended in the air, and there is a risk that at least a part of the shelf post, mounting bracket, and support bracket will be deformed and the inner showcase will come off the shelf post. During the maintenance and inspection of the evaporator and the cooling air circulation fan of the case, I was forced to remove the inner showcase and put it out of the outer showcase.

In order to solve the above problems, the present invention provides a movable case as a case arranged in a storage chamber.

<D> Means for Solving the Problems As a means for solving the above problems, the present invention arranges a cool air passage provided with a blower fan and a drain outlet and a space between the cold air passage and the bottom surface of the storage chamber with a space. And a pair of front and rear elongated rail members each having a paragraph portion and a track portion positioned higher than the paragraph portion, a plurality of bottom plates having front and rear edges mounted on the paragraph portions of the rail member, and the storage chamber And a movable case in which a pair of front and rear casters provided on the bottom wall are mounted on the track portion.

<Effect> According to the above means, the pair of front and rear rail members arranged at the boundary between the storage chamber and the cold air passage function as support members for mounting the bottom plate and the movable case, and both front and rear edges of the bottom plate are arranged. Since the track part on which the caster orbits is higher than the paragraph part on which it is placed, the paragraph part does not act as a positioning part of the bottom plate and does not hinder the rolling of the caster. It acts as a guide when moving in the direction.

<F> Example An example of the present invention will be described below with reference to the drawings.

1 is an open showcase in which a main body is composed of a heat insulating wall 3 having an opening 2 for storing and taking out products on the front surface,
A pair of left and right heat insulating side plates 4 having transparent plates 4A at the front are provided on both left and right sides of the heat insulating wall 3, and a drain port 5 is provided at the bottom.
Is provided. Reference numeral 6 denotes a partition plate which is arranged at an appropriate distance from the inner wall of the heat insulating wall 3, and a storage chamber 7 and a cold air passage 8 are formed along with the installation of the partition plate. The partition plate 6
Is a top plate 9, a back plate 10, a plurality of detachable and slidable bottom plates 1
1, a front plate 12 and a pair of front and rear elongated metal rail members 13 arranged below the back plate 10 and the front plate 12 for mounting the respective bottom plates 11. The both rail members 13 are the bottom plates 11
In addition to forming a paragraph portion 14 on which both front and rear edges are placed, a track portion 15 on which a caster of a movable case, which will be described later, is placed is formed in a portion higher than the paragraph portion. Posts 17 for supporting a plurality of shelves 16 arranged in the left side area of the storage chamber 7 are provided on the left and right sides and the center of the back plate 10. The shelf 16 is erected and supported by a pair of known left and right cantilever brackets 18 which are removably engaged with the columns 17.

The cold air passage 8 has its outlet port 20 facing the upper edge of the opening 2 and its inlet port 21 facing the lower edge of the opening 2. The cold air that has undergone heat exchange is forcedly circulated by the blower fan 23 in the bottom area as shown by the arrow in FIG. 1 to form a cold air curtain AC in the opening 2 to cool the storage chamber 7. Along with this cold air circulation, a part of the cold air that has passed through the cooler 22 is blown out from the through holes 19 formed in the back plate 10 into the storage chamber 7, and the cold air in the lower area of the storage chamber 7 is the front plate. It is sucked into the cool air passage 8 through the through hole 24 formed in 12.

Reference numeral 25 denotes a movable case disposed in the right side area of the storage chamber 7, which is movable in the left-right direction, and includes a bottom wall 27 provided with two front and rear casters 26 for rolling the track portion 15 of the rail member 13, and the spine. A through hole opposed to the through hole 19 of the plate 10, that is, a back wall 29 having a large number of cold air intakes 28 formed therein, and the front plate having a lower back than the back wall.
12 through holes, that is, a front wall 31 having a large number of cold air discharge ports 30 formed,
A pair of left and right side walls 32 made of a transparent plate, a ceiling wall 33, and a straddle provided between the ceiling wall and the front wall 31, and hinged to the ceiling wall 33 so as to be vertically rotatable. It consists of a transparent door 35 which is pivotally supported and inclines to the front and descends, and has a step-like article support base 36 inside and a metal storage container supported by this support base.
37 are arranged. The movable case 25 takes in cool air.
By taking in from 28 and discharging from the outlet 30, cold air passes through the inside, and the food in the storage container 37 is cooled. Since the movable case 25 is provided with the transparent door 35 on the front surface, the temperature inside thereof is kept lower than that of the storage chamber 7. Further, since the transparent door 35 of the movable case 25 is inclined forward and downward, it serves as a guide for the inner flow of the air curtain AC when the door is closed, and improves the laminar flow characteristics in the downstream region of the air curtain AC.

When the amount of cold air passing through the movable case 25 is adjusted, a shutter 40 made of a perforated plate that slides in the left-right direction may be provided below the back plate 10 as shown in FIG. 4 as another embodiment.

When the blower fan 23 in the bottom area of the cool air passage 8 on the lower right side of the storage room 7 is inspected or the bottom surface is cleaned, the movable case 25 is pushed to the left by removing the middle and lower shelves 16 and then pushing it to the left. Rolls on track 15 and moves to the left,
In such a state, by removing the bottom plate 11 on the right side, the blower fan 23 can be inspected and the bottom surface can be cleaned.

According to such a configuration, the pair of front and rear rail members 13 arranged at the boundary between the storage chamber 7 and the cold air passage 8 act as support members for mounting the bottom plate 11 and the movable case 25, and at the same time, the bottom plate 11
Since the track portion 15 on which the caster 26 orbits is higher than the paragraph portion 14 on which both front and rear edges are placed, the paragraph portion 14 causes the bottom plate 11 to move.
Does not hinder the rolling of the casters 26 and acts as a guide when the bottom plate 11 immediately below the movable case 25 is laterally moved.

Therefore, since the load of the movable case 25 is received by the rail member 13 on the bottom surface of the storage chamber 7, the weight of the movable case 25 and the food stored in the movable case is transmitted to the rail member 13, and thus the conventional case. This prevents accidents caused by the inner showcase being suspended in the air.

Further, since the movable case 25 can be moved in the left-right direction, the plurality of bottom plates 11 can be freely attached and detached.
The inspection of 23 and the cleaning of the bottom area of the cold air passage 8 can be easily performed by moving the movable case 25 and removing the bottom plate 11, and the heavy labor of taking out the movable case 25 to the outside of the storage chamber 7 can be avoided.

<G> Effects of the Invention The above-described invention has the following effects.

Since the load of the movable case is received by the rail member on the bottom of the storage chamber, the weight of the movable case and the food stored in the movable case is transmitted to the rail member, and as a result, it is safe without danger. The movable case can be placed at a place, and it is easy to move the movable case to change its position.

As the movable case can be moved to the left and right, multiple bottom plates can be attached and detached.Therefore, when inspecting the blower fan and cleaning the bottom area of the cold air passage, move the movable case while storing food. This can be easily done by removing the bottom plate, and the heavy labor of taking out the movable case out of the storage room can be avoided.
