Description

[Detailed description of the invention] The present invention relates to an improved configuration of a vertical cooling storage with an opening on the top surface, and in particular, a cooler and a condenser are installed in both the inner and outer boxes.

Conventionally, this kind of storage has a cooling pipe wound around the outer periphery of an inner box forming a storage chamber, but most of the condensers are arranged in a machine room at the bottom of the main body.

This is because if the condensing pipe is wound around the inner circumferential surface of the outer box, the cooling pipe of the inner box and the condensing pipe will face each other in close proximity, which is undesirable because the cooling efficiency will decrease.

Therefore, in order to install cooling and condenser pipes in both the inner and outer boxes, the capacity of the refrigerant compressor must be increased, which is uneconomical.Especially in small storage, the space between the inner and outer boxes is narrow, and the above-mentioned The negative effects were great.

This proposal was developed in view of these points, and the figure will be explained below.

1 is an inner box 2 and an outer box 3 that are open on the top surface, and both of these boxes 2.
, 3, the upper surface opening of the storage chamber 5, which opens on the upper surface formed by the inner box 2, etc., is closed by a lid plate 6 so as to be openable and closable. There is.

The outer periphery of the inner box 2 made of a suitable material such as synthetic resin contains a refrigerant compressor 8 disposed in the machine room 7 at the bottom of the main body 1, a condensing pipe 9 attached to the inner circumferential surface of the outer box 3, etc. The cooling pipe 10 constituting the cycle is attached by winding or the like.

The cooling pipe 10 is disposed biased toward the upper part of the inner box 2, and the condensing pipe 9 installed on the inner peripheral surface of the outer box 3 made of a suitable material such as synthetic resin does not face the cooling pipe 10. The cooling pipe 10 is biased downward from the cooling pipe 10, and the outer box 3 serves as a heat sink.

As described above, in this case, the cooling pipe is placed above and the condensing pipe is placed below, and the two pipes are configured so that they do not face each other, so the heat dissipated from the condensing pipe has almost no negative effect on the cooling pipe. Cooling efficiency can be improved without any problems.

Moreover, there is no problem even if the distance between the inner and outer boxes is narrow, and the main body can be made smaller without increasing its size.

Furthermore, since the cooling pipe is located at the top of the inner box, there is little drop in cooling efficiency due to the downward flow of cold air in the storage compartment.
Since the condensing pipe is located at the bottom, the temperature of the outer surface of the upper part of the main body, which is easily touched by the operator, does not reach high temperatures, and burns and discomfort are almost never caused.
