Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a small stationary type ice maker that makes and stores ice cubes for drinks, etc., and in particular, the top, both sides and back of the casing are Pertains to things that are enclosed or constrained and installed in a structure.

(Prior Art) In recent years, this type of ice making machine has been made smaller due to the limited installation space. As part of this, the applicant filed an earlier application (Japanese Patent Application No. 127351/1983).
A circular ice-making plate body having a plurality of vertical partition walls protruding from its surface, vertical partition walls protruding from the main body at positions corresponding to the vertical partition walls, and horizontal partition walls between adjacent vertical partition walls. A number of ice-making cells with one side open are formed by stacking the same annular spacers alternately, and cooling pipes are heat-transferably attached to the back side of the main body to form a water tank in the upper part. He proposed a cylindrical ice-making unit in which the water flowing down from the ice-making cell is frozen in each of the ice-making cells, thereby increasing the ice-making capacity and making it possible to reduce the size of the ice-making machine accordingly.

(Problem to be solved by the invention) Therefore, the inventor of the present invention made use of this proposal to create an ice storage compartment located within the casing, with the upper part serving as the ice making compartment where the ice making unit is placed, and the lower part serving as the ice making compartment. If it is partitioned into an ice storage compartment, the space required for the ice storage compartment will be small, and the space for the ice storage compartment can be enlarged accordingly.Also, as the ice storage compartment becomes smaller, a compressor, condenser, etc. will be installed on the side of the ice storage compartment. It was devised that the machine room where the casing can be placed can be effectively partitioned, and as a result, the entire casing can be made smaller.

However, in order to make effective use of the installation space in such an ice maker, when the top, both sides, and back of the casing are surrounded or restrained by surrounding structures (counter table, wall, etc.) when the ice maker is installed, The opening positions of the inlet and outlet for supplying and exhausting the condenser in the machine room are subject to significant restrictions because of the space required for intake and exhaust. Therefore, for example, if the suction port and the blowout port are provided at the front of the machine room of the casing, the direction of the suction and the blowout will be changed by approximately 180°, so
The flow resistance of the cooling air for the condenser inside the aircraft is large,
There is also the problem of short circuits.

In view of these points, the present invention aims to reduce the size of the casing while still allowing air intake and exhaust from the condenser to be carried out inside the aircraft even when the top, both sides, and back of the casing are surrounded or restrained by surrounding structures. The main purpose of this is to enable this to be carried out easily without increasing flow resistance or short circuits.

Furthermore, the present invention aims to achieve both expansion of the ice storage compartment and improved cooling of the compressor by considering the arrangement of each device in the machine room and the structure of the outlet. shall be.

(Means for solving the problem) In order to achieve the above object, the solution means of the present invention is as shown in FIGS.
The present invention is directed to an ice making machine that is installed with its top surface 1b, both side surfaces 1c, 1c, and back surface 1e surrounded or restrained by surrounding structures C. Legs 2 are provided protruding from the bottom surface 1d of the casing 1. Inside the casing 1, a machine room 5 in which a compressor 12, a condenser 13, a condenser fan 14, etc. are arranged is defined on the side of the ice storage 4 by an ice storage 4 disposed in the casing 1, and a machine room 5 is formed on the side of the ice storage 4. Inside the refrigerator 4, the upper part is divided into an ice making compartment 6 in which an ice making unit 8 is disposed, and the lower part is divided into an ice storage compartment 7. A suction port 17 is provided on the bottom surface 1d of the casing at the bottom of the machine room 5.
There is an air outlet 1 on the front side of the casing 1a at the front of the machine room 5.
8 is provided. The condenser 13 is arranged in the machine room 5 facing the suction port 17, the compressor 12 is arranged in the upper part of the machine room 5, and the fan 14 is connected to the condenser 13 in the machine room 5. 13 and is arranged close to the top. The air outlet 18 consists of a main air outlet 18a that opens at the center of the front surface 1a of the casing 1, and an auxiliary air outlet 18b that opens at the upper part of the front surface 1a of the casing 1. A main air passage 19a through which the air that has passed through the condenser 13 flows directly to the main air outlet 18a, and an auxiliary air passage 19b through which the air that has passed through the condenser 13 passes through the outer periphery of the compressor 12 and flows to the auxiliary air outlet 18b are formed. The structure is as follows.

(Function) As a result, the suction port 1 on the bottom surface 1d of the casing has the suction space formed by the legs 2.
After exchanging heat with the condenser 13, the air sucked into the machine room 5 from 7 is turned by approximately 90 degrees to the exhaust space from the outlet 18 (main outlet 18a and auxiliary outlet 18b) on the front surface 1a of the casing. The air can be blown forward from the casing 1 with ample room.

Furthermore, in the present invention, by arranging the compressor 12 above the machine chamber 5, the volume of the ice storage chamber 7 can be made as large as possible, and the amount of ice stored can be increased. Compressor 12 can be effectively cooled by air.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figures 1 to 4 show an ice maker A which is an embodiment of the present invention, and the ice maker A has legs 2, 2, ... projecting downward from the four corners of the bottom surface 1d of the casing 1. At the same time, an opening/closing door 3 for taking out ice is provided on the left side of the center of the front surface 1a of the casing 1, and as shown in FIG. The upper surface 1b, both side surfaces 1c, 1c, and back surface 1e of the casing 1 are surrounded and covered by the structure C, and the casing 1 is fitted into the housing section B and placed there. Here, when placed in the housing part B, a gap S is formed below the bottom surface 1d of the casing 1 by the legs 2, and the front surface 1a of the casing 1 is open.

Inside the casing 1, there is a box-shaped ice storage 4 with an open top and front surface on one side 4a.
(the left side in the figure) is placed in contact with the casing side 1c, and inside the casing 1, a machine room 5 is partitioned and formed on the side (right side) of the ice storage 4 by the ice storage 4. In addition to the ice storage 4
Inside, the upper part is divided into an ice making compartment 6 and the lower part is divided into an ice storage compartment 7.

An ice making unit 8 is arranged in the ice making compartment 6. The ice making unit 8 includes an annular ice making plate main body 9 made of a heat transfer material such as aluminum having a plurality of vertical partition walls 9a protruding from the surface thereof, and an ice making plate body 9 located corresponding to the vertical partition walls 9a of the main body 9. Vertical partition wall 10a...
A similar annular spacer 10 made of a heat insulating material such as resin is stacked alternately, with a horizontal partition wall 10b provided between adjacent vertical partition walls 10a and 10a, and one side is left open. A cylinder in which a large number of ice-making cells 11 are formed, and water flowing down from above through a cooling pipe (not shown) heat-transferably attached to the back surface of the main body 9 is frozen in each ice-making cell 11. The cylindrical shape increases the ice making capacity, and the ice making capacity is accordingly reduced, so that the volume of the ice making chamber 6 can be reduced. Further, for this reason, the other side surface 4b (right side surface) of the ice storage compartment 4 is formed such that the upper part is recessed inwardly and bulges outward from the center part to the lower part, so that the ice storage compartment 7
This increases the volume of ice storage, that is, the amount of ice stored.

Further, in the machine room 5, there are provided a compressor 12 and a condenser 13 constituting a refrigeration cycle for the ice making unit 8, a condenser fan 14, a switch box 15 containing electric control equipment, and the like. The compressor 12 is arranged and fixed in the upper part of the machine room 5 via a mounting plate 16 having a communication hole 16a in the center, and the condenser 13 is installed in the lower part of the machine room 5 through a suction port 17, which will be described later. A condenser fan 14 is disposed facing each other and near the downstream (upper side) of the condenser 13 . Further, the switch box 15 is attached to the back of the center of the front surface 1a of the casing at the front of the machine room 5. The lower surface of the switch box 15 is formed into an inclined surface 15a that slopes diagonally downward from the front to the rear, suppressing the air flow resistance and smoothly blowing out the air from the main air outlet 18a, which will be described later. I try to do it.

Furthermore, the bottom surface 1 of the casing at the bottom of the machine room 5
d, a rectangular suction port 17 is opened corresponding to the condenser 13, and an air outlet 18 is provided on the front surface 1a of the casing at the front of the machine room 5. The air outlet 18 includes a rectangular main air outlet 18a that opens at the center of the casing front surface 1a (a portion below the switch box 15), and a rectangular main air outlet 18a that opens at the center of the casing front surface 1a (a portion below the switch box 15).
a, and a slit-shaped auxiliary air outlet 18b that opens at the upper part (above the switch box 15), so that the air that has passed through the suction condenser 13 from the suction port 17 by the fan 14 is transferred to the main air outlet 18.
a main air passage 19a flowing into the condenser 13
An auxiliary air passage 19b is formed through which the air after passing passes through the communication hole 16a of the mounting plate 16 and the outer periphery of the compressor 12 and flows to the auxiliary outlet 18b.
Note that 20 is an air outlet grill attached to the main air outlet 18a, and 21 is a fixed leg for fixing the compressor 12 to the mounting plate 16.

Therefore, in the above embodiment, ice maker A
is placed in the storage part B of the structure C with the top surface 1b, both side surfaces 1c, 1c, and back surface 1e of the casing 1 surrounded, the legs 2... are formed below the bottom surface 1d of the casing 1. The gap S becomes an intake space, and air is smoothly sucked into the machine room 5 by the fan 14 from the suction port 17 on the bottom surface 1d of the casing. After the air sucked into the machine room 5 exchanges heat with the condenser 13, the air is turned by approximately 90 degrees and flows into the air outlet 18 (the main air outlet 18a and the auxiliary air outlet 18b) on the front surface 1a of the casing. The air is smoothly blown out from the air outlet 18 to the front of the casing 1 where there is sufficient exhaust space. Therefore, when stationary, the condenser 13 can be smoothly supplied and discharged without creating a special intake/exhaust space, and since air intake and blowout can be done by changing direction by approximately 90 degrees, it is possible to The flow resistance of the fan 14 can be suppressed to a low level, and the occurrence of short circuits can also be suppressed, and the driving loss of the fan 14 can be reduced.

In that case, the air outlet 18 is the main air outlet 1.
8a and the auxiliary air outlet 18b, a main air passage 19a and an auxiliary air passage 19b are formed in the machine room 5. Among them, the air flowing through the main air passage 19 passes through the switch box 1 provided at the front of the machine room 5.
5 is formed into an inclined surface 15a, the air is guided to the main air outlet 18a without resistance, thereby further reducing the flow resistance and smoothing out the air. On the other hand, since the air flowing through the auxiliary air passage 19b cools the compressor 12 when passing around the outer periphery of the compressor 12, overheating of the compressor 12 can be effectively prevented.

Furthermore, in the ice maker A, the compressor 12
As well as the upper part of the machine room 5, as the ice making unit 8 becomes smaller due to the improved ice making capacity, the ice storage capacity of the ice storage compartment 7 can be increased accordingly, and the ice storage amount can be improved. The upper space can be enlarged, and this space can be used effectively to effectively arrange a large compressor 12 in accordance with the increase in ice making capacity.
Therefore, the overall size of the casing 1 can be effectively downsized by effectively utilizing the space while improving the ice making capacity and ice storage capacity.

(Effects of the invention) As described above, according to the invention, even when the top surface, both side surfaces, and the back surface of the casing are surrounded or restrained by the surrounding structures and are placed, the downward suction can be reduced while reducing the size of the casing. And forward air blowing allows air supply and exhaust to the condenser without requiring special air intake and exhaust space, while reducing the flow resistance inside the machine and suppressing the occurrence of short circuits, thus saving installation space. Therefore, it is possible to provide a suitable small-sized ice maker that can overcome the limitations.

Furthermore, by locating the compressor above the machine room and dividing the air outlet into a main air outlet and an auxiliary air outlet to form a main air passage and an auxiliary air passage, ice making capacity and ice storage capacity are improved and space inside the machine is effectively utilized. This has the advantage of being able to effectively prevent overheating of the compressor while further downsizing the compressor.
