Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is equipped with a fan and a cooler in a cool air circulation passage formed in a main body case having a U-shaped cross section, and circulates cold air in the refrigerator to circulate the main body. The present invention relates to a suction port device for forming a periphery of a suction port of a cold air circulation path in a cold air circulation type showcase in which a cold air curtain is blown out and formed in a front opening of a case and the inside of a refrigerator is cooled.

[Conventional technology]

An open showcase shown in FIG. 10 is known as a cold air circulation type showcase. In the figure, the open showcase includes a main body case 1 having a U-shaped cross section having an opening 1a on the front surface. The main body case 1 is composed of an outer box 2 and an inner box 3 which are heat insulating walls, forms an inside 4 of the inner box 3, and circulates cold air between the outer box 2 and the inner box 3. Forming a path 5. Both ends of the cold air circulation path 5 face the opening 1a to form an inlet 5a and an outlet 5b, respectively, and a fan 6 and a cooler 7 are provided inside. Reference numeral 8 is a shelf that divides the interior 4 into a plurality of upper and lower stages.

In the open showcase, a large number of products are displayed in the storage 4. In addition, the fan 6 sucks the air inside the storage
The air is drawn into the cold air circulation path 5 through 5a, and is circulated in the direction of the arrow without the cool air through the cooler 7. Then, the cold air is blown from the air outlet 5b toward the air inlet 5a to form a cold air curtain in the opening 1a and cool the interior 4.

Members are arranged around the suction port 5a as shown in FIGS. 11 and 12, and constitute the suction port device 10 which is the object of the present invention. That is, on the rear surface of the rising portion 2a of the outer box 2, cover hooks 11 extending along the longitudinal direction of the outer box 2 and a plurality of cover supports 12 arranged at appropriate intervals along the longitudinal direction.
Are fixed by screw members. An upper end portion is hooked on the cover fitting 11 and an upright portion is supported by a cover support 12, and a suction port cover 13 having a hook-shaped cross section is attached. This suction port cover 13 has a large number of ventilation holes 13a on its upper surface,
The upright surface portion 13b also serves as the upright side of the inner box 3, and the supporting metal fitting 14 is removably engaged with the upright surface portion. Then, the deck pan 3a forming the bottom plate of the inner box 3 is detachably attached with its front end supported by the support metal fitting 14. Further, a fence 15 is provided so as not to block the ventilation hole 13a by placing an article on the suction port cover 13. The fence 15 is supported by the suction port cover 13 by fixing the support rods 15a protruding downward at appropriate intervals to the upright portion 13a by the stoppers 16.

[Problems to be solved by the device]

By the way, in the conventional suction port device 10, when it is desired to remove the fence 15 when storing the product in the refrigerator 4, the fence 15 cannot be removed unless the fastener 16 is loosened using a tool such as a screwdriver. It is complicated to put on and take off, and the fan 6
There was a problem that the deck pan 3a was caught by the stopper 16 and was difficult to remove when the deck pan 3a was removed for the inspection of the cooler 7 and the cooler 7.

An object of the present invention is to provide a suction inlet structure of a cold air circulation showcase in which a fence can be easily attached and detached and a deck pan can be easily attached and detached.

[Means for Solving the Problems]

In order to achieve the above object, according to the present invention, a cold air circulation path is formed in a main body case having a U-shaped cross section and having an opening in the front surface and forming an inside of the cold storage. The suction port facing the opening is provided with a suction port cover having a substantially hook-shaped cross section and having a large number of ventilation holes on the upper surface thereof, and a fence standing upright on the upper surface of the suction port cover. In the suction device of the cold air circulation type showcase, while supporting rods are projected downward from the fence,
A support hole through which the support rod penetrates is provided on the upper surface of the suction port cover, and a part of the vertical surface of the suction port cover is cut and bent to form a support portion that supports the support rod together with the support hole. It shall be.

[Action]

The fence is attached only by engaging the support rod through the support hole and engaging the support portion, and the attachment and detachment thereof is extremely easy. In addition, the inner surface of the suction port cover does not have a protrusion like a conventional fastener, and the deck pan can be smoothly attached and detached.

〔Example〕

FIGS. 1 and 2 show a first embodiment of the present invention, in which parts common to or the same as those in FIGS. 10 to 12 are designated by the same reference numerals.

In FIG. 1 and FIG. 2, the suction port cover 13 has a support hole 13c through which the support rod 15a penetrates at the upper surface thereof. In addition, a support portion 13d is formed on the upright surface portion 13b by cutting a part of it into a U-shape and bending this portion toward the cold air circulation path 5 side in a hook shape to receive the tip of the support rod 15a.

In the above-mentioned configuration, the fence 15 has its supporting rod 15a,
The tip is inserted into the support hole 13c so that it comes into contact with the support portion 13d, so that the tip is supported by the suction port 13 and stands upright on the upper surface thereof. When removing it, pull it out upwards. Therefore, the fence 15 can be attached and detached very easily. On the other hand, when removing the deck pan 3a, pull it up as it is,
With nothing in the way, the deck pan 3a can be easily removed. The same applies to mounting.

3 to 5 show a second embodiment of the present invention. The difference from the above-mentioned embodiment is that the suction port cover 13 is provided with two U-shaped slits on the upper and lower sides, and this portion is bent horizontally. Support parts 13e, 13f are formed by the
This is the point where a support hole 13g through which 15a penetrates is opened.

In this embodiment, the fence 15 is held at a predetermined height by the support portion 13f, and the support rods 15 are supported by the support holes 13a and the support 13g so that the fence 15 stands upright on the upper surface of the suction port cover 13 without tilting back and forth. Therefore, the same effect as in the first embodiment can be obtained with respect to the attachment / detachment of the fence 15 and the deck pan 3a.

FIGS. 6 to 8 show a third embodiment of the present invention. In this case, the cover support 12 has a support hole 12a similar to the support portions 13e and 13f of the second embodiment. The part 12b and the support part 12c are formed. Also in this embodiment, the same effects as those of the first and second embodiments can be obtained. As shown in FIG. 9, instead of forming the supporting hole 12a, the supporting portion 12b is formed by squeezing out a portion surrounded by two upper and lower cutting lines.
It is also possible to form it as d.

[Effect of device]

According to the present invention, in a main body case having a U-shaped cross section that has an opening in the front and forms the inside of the refrigerator, an opening of a cold air circulation passage formed so as to surround the inside of the casing is opened. Suction of a cold air circulation showcase in which a suction port cover with a substantially hook-shaped cross section and a large number of ventilation holes is provided on the upper surface of the suction port, and a fence is provided upright on the upper surface of the suction port cover. In the mouth device, a supporting rod is provided so as to project downward on the fence, a supporting hole through which the supporting rod penetrates is provided on the upper surface of the suction port cover, and a part of the vertical surface of the suction port cover is cut. Since the supporting part supporting the supporting bar is formed together with the supporting hole by bending, the fence can be attached and detached very easily, and the deck pan that forms the bottom plate of the inner box that forms the inside of the refrigerator can be very easily performed. Can be attached and detached
