Description

[Detailed description of the invention] The present invention relates to an automatic ice maker, and in particular, the arrangement of the compressor and condenser increases the amount of ice stored and makes it easier to take out the ice, and also facilitates water supply and drainage.
It relates to new improvements to improve ice-making capacity, save energy, etc.

There are various types of automatic ice makers that have been used in the past, and those that are popular for commercial use in cafeterias, coffee shops, etc. have a daily production capacity of about 15 kg to 200 kg, and are available in a variety of formats, from tabletop types to stationary types. However, the present invention is especially suitable for medium-sized vehicles of 20Kg/day and above.
It is suitable for application to so-called vertical type ice makers, which are often found in models that produce about 100 kg/day.

FIG. 1 shows a typical configuration of this type of vertical type automatic ice maker that has been conventionally used. As shown in the figure, the main body 1 of the automatic ice maker has a rectangular box shape as a whole, has a foam insulation layer 2 inside, and is composed of a top plate 4 and a side plate 5 made of metal plates. A front door 7 having a front door gasket 6 is provided on the front surface to be airtight and openable and closable.

A front panel 9 having ventilation holes 8 is attached below the front door 7 of the main body 1, and an ice storage 10 and a machine room 11 are installed in the main body 1 at positions corresponding to the front door 7 and the front panel 9. is formed, and this ice storage 1
An ice making mechanism section 12 is disposed above the ice making mechanism 12.

The bottom plate 13 of the main body 1 is formed into a completely horizontal plane, and the bottom plate 13 is provided with legs 14, and the top surface of the bottom plate 13 is mounted with a compressor 15 and a condenser 16. It is being

Since the compressor 15 and the condenser 16 have different heights, an inclined surface portion 10b is formed on the bottom 10a of the ice storage 10 to make the ice storage 10 as narrow as possible.
It is designed to increase the internal volume.

However, in the above configuration,
When opening the front door 7 and taking out the ice in the ice storage 10 with a scoop (not shown), the tip of the scoop hits the slope 10b because the slope 10b is formed facing the front door 7. This caused significant inconvenience in the work of removing ice.

Furthermore, since the space volume of the machine room 11 directly overwhelms the volume of the ice storage 10, it has been extremely difficult to increase the volume of the ice storage 10. moreover,
Although the exhaust hole of the machine room 11 is not shown in the drawing, it is provided on the side of the main body 1, that is, on the side perpendicular to the front door 7. When it is narrow, it is often used in close contact with a wall or other equipment, and in such cases the exhaust port is closed, making it impossible to install it in close contact with a wall or other equipment. It was hot. Further, although not shown in the drawings, if the bottom plate is lowered so that it almost touches the floor, the volume of the ice storage will increase, but on the other hand, the bottom part will not be able to be cleaned at all.

The purpose of the present invention is to provide an extremely effective means for quickly eliminating the various drawbacks mentioned above.In particular, the bottom plate of the main body is deformed into a step-like shape, so that the bottom plate is The first bottom plate part that is close to the
A second bottom plate part consisting of an inclined surface formed continuously to the first bottom plate part is provided, and a compressor is disposed on the first bottom plate part, and a condenser is installed in an inclined state on the second bottom plate part. It is characterized by a structure in which the ice storage can be formed in such a way that even if a scoop tip is inserted from the front door side, a bottom surface against which the scoop tip is not formed is formed.

Hereinafter, preferred embodiments of the automatic ice maker according to the present invention will be described in detail with reference to the drawings.

Note that the same parts as in the conventional example will be described using the same reference numerals.

What is indicated by the reference numeral 1 in the drawings is a main body having a substantially rectangular box shape as a whole. A front door 7 having a front door gasket 6 is provided on the front surface of the device 1 to be airtight and can be opened and closed.

A front panel 9 having ventilation holes 8 is attached to the body part 1 through a filter 9a.
Inside, an ice storage 10 and a machine room 11 are formed at positions corresponding to the front door 7 and front panel 9, and an ice making mechanism section 12 is disposed above the ice storage 10. The machine chamber 11 is formed on the front side of the paper in FIG. 2, and its width when viewed from the right side in FIG. 2 approximately corresponds to the width of a filter 9a, which will be described later. The entire bottom plate 13 that defines the machine room 11 together with a surrounding plate (to be described later) has a stepped shape, and a flat first bottom plate portion 13a formed at one end of the bottom plate 13 is connected to the floor F (see FIG. 3). ), and an adjusting bolt 13b is attached to the first bottom plate portion so as to be height-adjustable.
The three legs 14a, 1 attached to the other corners of
Together with 4b and 14c, the main body part 1 is supported on the floor surface.

A compressor 15 is mounted on the first bottom plate portion 13a of the bottom plate 13.
is fixed horizontally, and a condenser 16 is installed at an angle with respect to the horizontal on a second bottom plate part 13c that constitutes an inclined surface continuously extending upward from the first bottom plate part 13a. A cooling fan 17 attached to the cooling fan 16 blows outside air from the air supply hole 1a of the main body 1 to the compressor 15 through the condenser 16.

As shown in FIG. 3, which is a cross-sectional view taken along the - line in FIG. 18 and 19, respectively, and the first shrouding plate 20 on the left side in FIG. 13
The second shrouding plate 20 on the right side, i.e., inside, is connected to the first bottom plate portion 13a at its lower end and to the bottom plate portion above the first bottom plate portion 13a at its upper end.

Furthermore, as can be understood from FIGS. 2 and 3, the bottom plate 13 is configured so that only the first bottom plate part 13a that supports the compressor 15 is lower than the other parts, and the second exhaust hole group 19 is , because it opens into the bottom plate space 21 formed by the bottom plate part 13e that does not participate in the definition of the machine room 11 and the second shroud plate 20, other equipment ( (not shown) are in close contact with each other, the inside of the machine room 11 can be exhausted from the second exhaust hole group 19 to the bottom plate space 21.

Furthermore, a third bottom plate portion 13d is formed continuously with the bottom plate portion 13c of the bottom plate 13, and the third bottom plate portion 13d is located higher than the first bottom plate portion 13a, and a leg portion 14a is attached to the third bottom plate portion 13d.
It is supported on the floor surface F by means of 4a, 14b and 14c and one adjustment bolt 13b.

As shown in FIG. 2, the ice storage 10 is defined by a panel material consisting of a foam heat insulating layer 2 and a resin plate 22, and the panel material is located in the upper horizontal part of the machine room located above the compressor 15. 10a, an inclined surface 10b formed above the condenser 16 continuously from the upper horizontal section 10a of the machine room, a bottom section 10c on the right side of the main body section 1, and a rising section 10d formed continuously from the bottom section 10c. and a side portion 10e, and the inclined portion 10b is inclined in a direction downward from the front door 7.

Furthermore, a drain port 23 is buried in the foamed heat insulating layer 2 between the bottom plate 13 and the bottom part 10c, and a water outlet 24 is formed in the drain port 23 to protrude into the bottom plate space 21. A drain pipe 25 is embedded in the groove 2a in the heat insulating material 2, and the water supply pipe 25 is connected to a water supply fitting 26 that projects downward from the bottom plate 13. Therefore, if a water pipe (not shown) is connected to the water supply fitting 26, the ice making mechanism section 1
2 can be supplied with ice-making water through a water supply pipe 25.

Furthermore, the condenser 16, as shown in FIG.
Since the second bottom plate portion 13c is installed on the inclined surface of the second bottom plate portion 13c so as to be inclined with respect to the horizontal, the amount of gas in the condenser 16 is lower than that of the horizontally disposed condenser 1 of the conventional configuration shown in FIG.
6, the load on the compressor is reduced, the current value is lowered, and a large energy saving effect can be obtained.

That is, when comparing the structure of the main body shown in FIG. 6 with the conventional structure shown in FIG. , go up the return bend 29 on the other side through the horizontal pipe (not shown) again, go down the return bend 30 through the horizontal pipe (not shown), and go down the return bend 31 through the horizontal pipe (not shown). Then, the vehicle ascends the return bend 32 again. In this way, the outlet pipe 3 moves up or down inside the copper pipe arranged in a serpentine shape.
3 in the direction of the arrow, and is cooled by the cooling fan 17, and the high-temperature, high-pressure gas condenses and becomes a liquid.

In this case, liquid accumulates in the riser pipes such as the return bends 29 and 32, but each return bend 29 and
The heights L ₁ and L ₂ between the inlet and outlet of 32 etc. are significantly different between the conventional example and the configuration of the present invention, and the apparent height of the riser pipe of the configuration of the present invention is different due to the inclined arrangement.
After the high _- temperature and high _- pressure gas is condensed, it quickly flows to the outlet pipe 33 and hardly accumulates in the refrigerant gas condenser 16, so less refrigerant liquid is required, and the starting characteristics are low. The voltage characteristics are improved and the performance of the ice maker is significantly improved.

In the above configuration, when operating the automatic ice making machine according to the present invention, first, tap water is supplied to the ice making mechanism section 12 via the water supply pipe 25, and the compressor 15 is turned on by turning on the power supply. Then, the cooling fan 17 of the condenser 16 starts rotating, and refrigerant is supplied to the ice-making mechanism 12, so that, for example, ice cubes begin to grow. When the ice cubes grow to a predetermined amount in the ice making mechanism section 12, each ice cube falls into the ice storage 10 through a deicing process. Ice storage of this invention 1
0, since the compressor 15 is located at a lower position than in the conventional configuration, its volume is extremely large and a large amount of ice cubes can be stored.

Next, in order to take out ice cubes from the ice storage 10, when the front door 7 is opened and a scoop tip (not shown) is inserted into the ice cubes in the ice storage 10, unlike the conventional configuration shown in FIG. Since there are no walls facing in the insertion direction, ice cubes can be taken out extremely smoothly.

Further, the cooled outside air taken in through the air supply holes 1a passes through a condenser 16 and a compressor 15 by a cooling fan 17, and is exhausted to the outside through exhaust hole groups 18 and 19 shown in FIG. 3.

Furthermore, the water that accumulates in the ice storage 10 is drained from the drain port 23.
The water can be discharged below the bottom plate 13 through the water outlet 24.

The automatic ice maker according to the present invention has the above-mentioned structure and function, so it is extremely easy to take out ice, the ice storage capacity is extremely large, and since there is no need for ventilation space, it can be placed in close contact with other equipment. Can be combined with

In addition, since the amount of gas in the condenser is small, the ice maker is inexpensive and has improved performance, can be started with low current and power consumption, and can be operated under low voltage.

Furthermore, since the water supply and drainage system can be installed on the underside of the bottom plate, it is easy to install water supply and drainage piping even when installed close to other equipment or walls, and the water part of the bottom plate is sufficiently far from the floor surface. Cleaning is also easy.

In addition, in this embodiment, the bottom plate has first, second,
Although the configuration in which the third bottom plate is provided has been described, the same effect can also be obtained with a configuration in which the second bottom plate is extended as it is and the legs are provided without forming the third bottom plate. be.
