Description

[Detailed Description of the Invention] The present invention relates to a structure for fixing a machine compartment cover in a show case.

Conventionally, a ferromagnetic engagement plate was attached to the front of the machine room frame at the bottom of the case using a metal support so that it could move slightly up and down and back and forth, while the upper end was attached to the lower front of the case body so that it could rotate. A structure is known in which a magnet is fixedly attached to the rear surface near the lower end of the machine room cover, and this magnet is attracted to an engagement plate on the front surface of the mount, thereby allowing the machine room cover to be opened and closed. However, in this case, the machine room cover is not firmly attached to the machine room frame, but is attached with a slight wobble, which causes a rattling sound due to operational vibrations from the machine room. There is a problem. Moreover, it has the disadvantage of high cost due to its complicated structure.

Therefore, an object of the present invention is to provide a fixing structure for a machine room cover that absorbs variations in the angle between the magnet and the surface to be attracted and that can be firmly fixed without wobbling, and that has a simple structure.

According to the present invention, in a structure in which the lower part of the machine room cover, whose upper end is rotatably attached to the front lower part of the case body, is removably fixed to the frame of the machine room, an opening is formed in the lower part of the machine room cover. an assembly including a magnet holder loosely inserted into the magnet holder and a magnet held by the magnet holder; a support plate fixed to the front surface of the machine room cover and extending so as to face the opening at a distance; , and a biasing member interposed between the assembly and the support plate, the biasing member elastically biasing the assembly toward the rear, the magnet holder having a rear end attached to the front surface of the machine room cover. the rear end surface of the assembly is attracted to the pedestal by the attraction force of the magnet;
This provides a structure for fixing the machine room cover in the show case, characterized in that the lower part of the machine room cover is fixed.

Examples will be described below with reference to the drawings.

FIG. 1 shows the entire structure of a frozen/refrigerated open case to which the present invention can be applied. This show case has a machine room 2 provided in the lower part of a case body 1. The machine room 2 houses a condensing unit consisting of a condenser 3, a blower 4, and a compressor 5, which can be freely drawn out. The case body 1 has an air passage 6 extending along the wall surface. An evaporator 7 and a blower 8 are arranged in the air passage 6, and the air is sucked in from the lower suction port 9 and is discharged from the upper discharge port 11 while being cooled. In this way, the articles stored in the interior 12 of the case body 1 can be displayed in a cooled state.

Further, a machine room cover 13 is provided in front of the machine room 2. As shown in FIG. 2, the machine room cover 13 is attached to the front lower part of the case body 1 by a cover attachment shaft 14 so that its upper end can rotate. Referring also to FIG. 3, a relatively large opening 15 is formed in the bent portion 13a at the lower end of the machine room cover 13, and a magnet or a magnet-containing member (hereinafter referred to as "magnet") is formed as shown in FIG. The magnet holder 17 that incorporates and holds the magnet holder 16
5. At this time, the magnet holder 17 is dimensioned to fit slightly loosely into the opening 15, and is prevented from coming off toward the machine room 2 by engaging pieces 17a and 17b that engage with the front surface of the bent portion 13a. It is becoming more and more common. The magnet holder 17 further includes a bent portion 13a of the machine room cover 13.
It is urged rearward by a biasing member 21, which also serves as a cushioning material, such as a sponge, which is interposed between the support plate 19, which is fixed to the front surface of the housing with screws, etc. 18. This biasing member 21 is a magnet 1
6 or fixed to at least one of the magnet holder 17 and the support plate 19. In this way, the magnet 16 and the magnet holder 17 are attached in such a manner that they are movable to some extent forward and up and down, but are locked at a certain position rearward, and are biased rearward. Therefore, even if the angles between the magnet 16 attached to the machine room cover 13 and the pedestal 22, which is the attraction surface of the magnet, do not match, the magnet 16 can move up and down, so the magnet 16 is attracted to the pedestal 22. It can be moved to an angle that is easy to move and can be at a different angle from the cover 13, and the entire magnet surface can be completely attracted to the pedestal 22. Furthermore, magnet 16
, the magnetic pole faces are shown in Fig. 4 with symbols 16a, 16b,
As shown by 16c, it has a structure in which it protrudes from the rear surface of the magnet holder 17 in a plurality of upper and lower parts, and also extends left and right. In this way, the machine room cover 13 is fixed in a state covering the front side of the machine room 2 by the magnet 16 being attracted to the front surface of the mount 22 made of a ferromagnetic material in the machine room 2. Furthermore, magnet 1
Machine room cover 1 so that the magnetic pole faces 16a, 16b, 16c of 6 are attracted to the pedestal 22 as uniformly as possible.
It is preferable to set the bending angle of the bent portion 13a of No. 3 in advance.

Although a specific type of show case has been described above, it goes without saying that the present invention can be applied to various types of show cases.

As explained above using the embodiments, according to the present invention, variations in the angle between the magnet and the surface to be attracted can be absorbed, and the magnet can be firmly fixed without wobbling.
Moreover, it is possible to provide a fixing structure for a machine room cover that absorbs vibrations and prevents the generation of noise and has a simple structure.
