Description

[Detailed Description of the Invention] The present invention relates to a so-called vertical low-temperature storage case equipped with upper and lower storage compartments.

First, a conventional example of such a show case will be explained, thereby clarifying the purpose of the present invention.

FIG. 1 is a longitudinal side view of a conventional vertical low-temperature storage case. In the figure, 1 indicates the upper storage 2 is a door attached to the front of the upper storage 1, and 3 indicates the lower storage. are arranged in a series, and a machine room 4 is provided further below the lower storage 3 to house refrigeration equipment such as a compressor 8, a condenser, and a blower.

The air intake part 6 of this lowermost machine room 4 is located at the front,
That is, it is provided at the lowermost part of the front surface of the entire show case, and exhaust is performed through an air passage secured by an exhaust part holder 5 that projects from the back of the machine room 4 when the show case is installed.

Note that the lower storage 3 is usually used to store products that are frequently taken in and out, so the opening 7 is equipped with a door,
Often there is no cover etc.

In a conventional low-temperature show case with such a structure, the opening 7 of the lower storage 3 is higher than the machine room 4, which may make it difficult for children etc. to take out products. 3
The depth is restricted by the opening 7, resulting in a thin design, and since the machine room 4 is at the bottom, it is easy to suck in floor dust etc. from the air intake part 6, and maintenance inspections and cleaning must be performed by bending down. It was inconvenient.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
In a show case with two storage compartments (upper and lower), the upper storage compartment can be deep, the lower storage compartment has a low opening for loading and unloading products so that it is easy for children to see and take out the products, and the machine compartment is designed to be dust free. To provide a low-temperature show case that is difficult to inhale and is easy to maintain, inspect, clean, etc.

However, according to the present invention, the purpose of the lever is to arrange the machine room of the refrigeration system between the upper and lower storage compartments in a low-temperature show case equipped with upper and lower storage compartments, and to connect the air intake section at the front of the machine compartment to the This is achieved by providing a communicating exhaust duct at the back of the upper storage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a longitudinal sectional side view showing an embodiment of the low-temperature show case of the present invention, in which the same components as in FIG. 1 showing the conventional example are given the same reference numerals.

A machine room 4 for storing refrigeration equipment such as a compressor 8 is arranged directly below an upper storage 1 having a door 2 on the front.
A lower storage 3 having an opening 7 for taking out products on the front upper surface is provided below the machine room 4.

Furthermore, if an opening/closing lid 9 is provided on the opening 7, cold air can be prevented from flowing out when products are not being sold, such as at night, and unnecessary energy consumption can be avoided.

The air intake part 6 is provided in the front of the machine room 4, but the location is selected so that it will not be blocked when the lid 9 is opened, and the back plate 10 of the machine room 4 is extended upwards to form the upper storage compartment. An exhaust duct 11 communicating with the air intake section 6 is formed on the back surface of the air intake section 6.

Since the low-temperature show case of the present invention is constructed as described above, it can exhibit the following effects.

(a) The opening for taking out products on the top of the lower storage can be made lower than in the past by the size of the machine room, making it easy for even short children to see and take out products.

(b) The space between the upper storage and lower storage becomes larger;
Even if the upper storage area extends forward, handling of the lower storage area will not be affected.

(c) The air flowing into the air intake section of the machine room is slightly cooled by the glass surface of the upper storage door, and since the air intake section is not close to the floor, there is less dust, etc. It is possible to increase the heat dissipation efficiency of an indoor refrigeration device and reduce dirt.

(d) The exhaust duct ensures an exhaust passage, and no special consideration is required for the layout.

(e) Maintenance, inspection and cleaning of the machine room can be carried out in a standing position, and can be carried out easily as it does not require an awkward position such as crouching down.
