Description

[Detailed description of the invention] The present invention is a meter installed in a cooling case equipped with a rectifying member having a large number of through holes at the air outlet. The purpose is to attach a flow regulating member to an air outlet.

Below, a conventional embodiment will be explained with reference to FIG. 1. Reference numeral 1 denotes a front-open type cooling case whose main body is composed of a heat insulating wall 2 with openings 3 for storing and taking out products. A cold air passage 7 in which a partition plate 4 is arranged at an appropriate distance from the inner wall and a cooler 5 and a blower 6 are installed, a storage room 9 provided with a plurality of shelves 8, and a storage room 9 located at the upper end of the opening in the longitudinal direction. A blow-off port 10 is formed, and a suction port 11 is located in the longitudinal direction of the lower end of the opening.The cold air flow formed by the cooler 5 and the blower 6 is forcedly circulated as shown by the arrow, and the storage chamber 9 is cooled. A low-temperature air curtain AC is formed in the opening 3 to protect the cold air mass in the storage room 9 from outside air.

Reference numeral 12 denotes a flexible flow regulating member having a large number of through holes 12a, 12a, . The cold air flow blown out through the opening 3 is rectified through the large number of holes to form a laminar flow.

This rectifying member can be a long one made by laminating and bonding multiple thin plates such as aluminum foil or resin sheets with textured front and back surfaces, or a rectangular one made by bonding and bonding multiple resin cylinders. Are known.

The flow regulating member is generally connected to the air outlet 10 by the insertion method shown in FIG. 2A or the screw fastening method shown in FIG. 3A.
can be attached.

The insertion method utilizes the elasticity of the flow regulating member 12 to push the flow regulating member into the air outlet 10, so it has the advantage of requiring no mounting parts and can be installed at low cost. Moreover, vibrations generated during transportation of the cooling case 1 cause drawbacks such as the rectifying member 12 coming off from the outlet 10, and the outlet of the through holes 12a, 12a... In order to intensively press a part of the side, the through holes 12a, 12a...
- Turbulent flow occurs in the cold air flow blown out through the opening 3 due to a partial blockage. This has resulted in drawbacks such as the formation of a turbulent region in a portion of the waist air curtain AC, leading to an increase in the refrigeration load.

Furthermore, in addition to the insertion method, the screw fixing method holds the outlet side of the flow regulating member 12 with the L-shaped plate 15 and the screws 16, so it has the advantage of being able to resolve separation of the flow regulating member 12 and uneven height during transportation. Similar to the insertion method, there is a drawback that a portion of the through holes 12a, 12a, . . . are blocked, and the fastening work becomes complicated.

Furthermore, when dust contained in the circulating cold air adheres to the inlet side of the rectifying member 12 and is removed from the air outlet 10 of the rectifying member 12 for cleaning, it is difficult to remove the rectifying member 12, and various methods are required to take it out. This also has the disadvantage of requiring the use of tools and damaging the rectifying member 12.

The present invention was developed in view of the above drawbacks, and examples thereof will be described below with reference to FIGS. 4 to 6.

Note that the same reference numerals in FIGS. 4 to 6 as in FIGS. 1 to 3 are the same.

Reference numeral 17 denotes a mounting member made of a heat insulating material such as synthetic resin, and includes a pair of holding parts 18a and 18 that hold both inner ends of the rectifying member 12.
b, notches 19, 19 to be accommodated in a movable part (described later), and a hanging part 21 in which a pivot hole 20 is formed.
Support part 22 in contact with the outer wall of the inner drawing board 13 defining 0
and is rotatably supported on this support part by a shaft 23,
When the rectifying member 12 is pushed in, a contact surface 24a1 that is approximately perpendicular to the support portion and in contact with the outlet side of the rectifying member 12 engages with a thank-like engaging portion 25 formed on the inner drawing board, which is formed on the opposite surface to this surface. The movable part 24 has an engaging piece 26 that acts as a finger hook when the rectifying member is pulled out, and a protruding piece 27 that serves as a finger grip when the rectifying member is pulled out, and the movable part 24 has an outer wall of the hanging part 21 and a contact surface 24a that are substantially on the same plane in the vertical state. It is configured.

Incidentally, FIG. 6 shows another mounting member.

Next, to explain how to attach the rectifying member 12, the holding parts 18a and 18b of the support part 22 hold both ends of the rectifying member 12, and the movable part 2
is rotated in the direction of arrow A to connect the contact surface 24a to the rectifying member 12.
In this state, press the movable part 24 to push the rectifying member 12 a little further back from the predetermined position, and while rotating the movable part 24 in the direction of arrow B, pull the engaging piece slightly downward. By engaging 26 with the engaging portion 25, it can be attached to a predetermined position of the air outlet 10 of the flow regulating member 12 using the attachment member 17.

Incidentally, in the case of removing the rectifying member 12, it may be done in the reverse order of attachment.

According to the above configuration, at least one side and both ends of the rectifying member 12 are held between the holding parts 18a and 18b of the supporting part 22, and the pushing of the rectifying member 12 and the engagement of the mounting member 17 are performed by operating the movable part 24. In order to do this, the height is adjusted by adjusting the degree to which the rectifying member 12 is pushed into the air outlet 10, and
The flow regulating member 12 can be easily attached to a predetermined position of the air outlet 10, and when the flow regulating member 12 is pushed in, the contact surface 24a of the movable part 24 closes the through holes 12a, 12a, .
・In order to disperse the pressing force applied to the through holes 12a, 12a
It is possible to prevent blockage of...

In addition, when removing and cleaning the rectifying member 12, the movable part 2
The flow regulating member 12 can be easily taken out from the air outlet 10 by simply disengaging the movable part 4 and pulling out the movable part.

Furthermore, by forming the mounting member 17 from a heat insulating material, it is possible to prevent dew condensation on the mounting member itself.

As described above, the present invention is a cooling case equipped with a flexible rectifying member having a large number of holes in the air outlet formed at one end of the opening for storing and taking out products, in which at least one side and both ends of the rectifying member are held. a support part having a holding part and in contact with one of the drawing plates defining the air outlet; a contact surface rotatably attached to the support part and moving the rectifying member to the back side of the air outlet when pressed; The flow rectifying member is attached to the air outlet with a mounting member formed on the opposite surface of this surface and comprising a movable part that also serves as a handle and has an engaging piece that engages with an engaging part formed on the drawing board. Therefore, the height of the rectifying member can be adjusted while adjusting the degree to which the rectifying member is pushed in, the contact surface can prevent the through hole from being blocked, etc., and the rectifying member can be easily installed.
You can ignore the turbulent flow of the air curtain caused by the blockage of the passage,
Furthermore, the rectifying member can be easily removed.
