Description

[Detailed description of the invention] Industrial application field This invention relates to an automatic ice maker.
In an automatic ice-making machine that produces a large number of ice cubes by spraying ice-making water from a tiltably arranged water tray to an ice-making chamber that opens downward, the ice-making mechanism can be partially stored inside a support member. The present invention relates to an ice-making compartment mounting structure that can reduce the size of the ice-making machine body and also facilitate the installation work of the ice-making compartment and the cleaning of the top surface of the ice-making compartment.

Prior Art An automatic ice maker of the type that continuously produces a large number of ice cubes by jetting and supplying ice-making water into a large number of ice-making chambers opened downward and freezing the ice-making water in the small chambers is as follows: It is suitably used in coffee shops, restaurants, and other kitchen facilities. The outline of the ice making mechanism in this injection type automatic ice maker will be briefly explained with reference to FIG. A large number of ice-making chambers 12 are defined which are open to each other. An evaporator 14 connected to a refrigeration system (not shown) is arranged in a meandering manner on the upper surface of the ice-making chamber 10, and the ice-making compartment 12 is forcibly cooled during ice-making operation.

Directly below the ice making compartment 10, a water tray 16 is mounted on a support shaft 18.
It is tiltably pivoted through the support shaft 18, and is held parallel to the ice making chamber 10 during ice making operation, and is biased by an actuator (not shown) during ice removal operation, so as to be tilted downwardly about the support shaft 18. It has become possible to tilt towards The water tray 16 includes:
A fountain hole 20 is bored corresponding to each ice-making chamber 12, and ice-making water 24 in a tank 22 is supplied from each fountain hole 20 to the corresponding ice-making chamber 12 via a pump 27. Ice making room 1
Ice cubes 26 are generated within 2.

Conventionally, this type of ice making chamber 10 has been installed in the casing of an automatic ice making machine with the configuration shown in FIG. i.e. ice maker housing (not shown)
A support member 2 made of, for example, a rectangular frame is placed above the
8 is arranged horizontally, and below this support member 28, the ice making chamber 10 is connected to the nut 3 via a sleeve-shaped spacer 30 and a bolt 32 inserted therein.
It is fixed by 4. Therefore, the parallel distance α between the support member 28 and the top of the ice making chamber 10 is kept constant by the spacer 30.

Problems to be Solved by the Invention The dimension α between the support member 28 and the ice-making compartment 10 described above is determined by the size α of the ice-making mechanism section 36 mainly composed of the ice-making compartment 10, the water tray 16, and the ice-making water tank 22.
is closely related to the "height dimension" within the ice maker body. For example, if the above-mentioned interval α is large, the arrangement position of the support member 28 in the ice making machine is constant, so the ice making mechanism section 36 is inevitably
is located relatively lower in the housing, and as a result, the main body of the ice maker becomes large compared to its ice making capacity. Furthermore, the fact that the ice-making mechanism section 36 is located below the housing means that the volume of the ice storage below the ice-making mechanism section 36 is limited, resulting in a disadvantage that the ice storage capacity is limited.

Therefore, if the space dimension α between the support member 28 and the ice-making compartment 10 is set to be small, the ice-making compartment 10
As a result of the evaporator tube 14 disposed in the ice making chamber 10 coming very close to the support member 28, the interval dimension α becomes small, making it difficult to clean the top surface of the ice making chamber 10. Therefore, the difficulty will be doubled.

Furthermore, the conventional method of attaching the ice making chamber 10 in a suspended state from the support member 28 by using a large number of sleeves 30 and bolts 32 requires a lot of time and effort as well as gap adjustment for the attachment work.

Purpose of the invention The present invention was devised to solve the above-mentioned problems, and aims to reduce the size of the ice-making machine body by reducing the height dimension of the ice-making mechanism. It is an object of the present invention to provide a means that can facilitate the installation work of the ice-making chamber and the cleaning of the top surface of the ice-making chamber.

Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention has an ice-making compartment that defines a number of ice-making compartments that open downward, and an ice-making compartment that tilts directly below the ice-making compartment. a water tray freely arranged horizontally, and water for ice making is injected and supplied from the water tray to each ice making compartment in a corresponding manner,
In an automatic ice-making machine that forms ice cubes in each ice-making compartment, projecting parts are integrally extended at both ends of the ice-making compartment, and the ice-making compartment is mounted on a support member installed at the top of the machine. The present invention is characterized in that an opening is defined with a size that allows the ice-making chamber to be placed therein, and a flange portion on which a projecting portion of the ice making chamber can be placed is integrally formed adjacent to the opening.

Embodiments Next, the automatic ice making machine according to the present invention will be described below with reference to preferred embodiments and the accompanying drawings. Note that the same members that have already been shown in the conventional automatic ice making machine described in connection with FIGS. 6 and 7 will be designated by the same reference numerals.

FIGS. 1 and 2 show an ice-making compartment mounting structure which is the gist of the present invention, and the ice-making compartment 10 basically has the structure described in connection with FIG. 7. However, at both ends of the top of the ice making chamber 10 in the width direction, projecting parts 10a, 10a are integrally formed, which are at the same level as the top and extend horizontally by a predetermined dimension in opposite directions, respectively. There is. The projecting portion 10a is provided with through holes 10b formed at required intervals through which tassel pin screws 40, which will be described later, are fixed to the flange portion are inserted. Incidentally, on the upper surface of the ice making chamber 10, an evaporation pipe 14 is arranged in a meandering manner and is connected to a refrigeration system (not shown).

As shown in FIGS. 1 and 2, the support member 28 horizontally disposed above the ice maker main body 42 is
Preferably, it is constructed as a frame made of a hard synthetic resin material with high rigidity, and its center part has a rectangular shape with dimensions that allow the main body of the ice-making chamber 10, excluding the protruding parts 10a and 10a, to be exposed. An opening 28a is defined therein. Also, this opening 28a
A flange portion 28, which functions as a kind of support surface, is adjacent to both opposite end edges in the transverse direction of the flange portion 28.
b, 28b are integrally formed. The flange portions 28b, 28b allow the ice making chamber 10 to be placed correspondingly on the respective projecting portions 10a, 10a.

Further, the flange portions 28b, 28b include a fourth
As can be seen from the figures and FIG.
It is preferable to provide a plurality of grooves 28c that are gently inclined toward the openings 28a of No. 8 at required intervals. This groove portion 28c is formed in the ice making chamber 1 as described later.
This is effective in preventing damage to the member due to freezing of water droplets that have entered between the projecting portion 10a and the flange portion 28b when the 0 is placed on the supporting member 28. Further, a blind hole 28d is bored in a portion of the flange portion 28b other than the concave portion of the groove portion 28c, and as described later, the ice making chamber 10 is connected to the overhanging portion 10a.
When placed on the flange portion 28b,
The tuft pin screw 40 can be forcibly screwed and fixed into this blind hole 28d.

Note that the opposing vertical wall surfaces defining the opening 28a of the support member 28 and the opposing vertical wall surfaces rising successively from each flange portion 28b form a space surrounded by a rectangular wall above the opening.

The ice making chamber 10 configured as described above is attached to the support member 28 as follows. That is, as shown in FIG.
8a is completely opened. In this state, if the ice-making compartment 10 is lowered toward the opening 28a with the ice-making compartment 12 facing downward, the main body of the ice-making compartment 10 faces into the opening 28a, and the ice-making compartment 10 Both overhanging parts 10a, 10a
is the flange portion 2 integrally formed with the support member 28.
8a and 28a in close contact with each other.

In this case, the through holes 10b bored in the projecting parts 10a, 10a and the flange parts 28a, 2
If the dimensions are set so that the blind holes 28d provided in the blind holes 8a are aligned in the vertical direction, the ice making chamber 10 can be reliably attached using the tuft pin screws 40 inserted therein. Note that the groove portion 28c recessed in the flange portion 28a allows water droplets that have entered between the overhang portion 10a of the ice making chamber 10 and the flange portion 28b to escape to the outside.
This effectively prevents damage to each member due to water droplets freezing and expanding in volume during ice-making operation. If a lid member 44 made of a heat insulating material as shown is removably attached to the upper end surface of each vertical wall of the support member 28, cold air will not escape to the outside during ice making operation.

Effects of the Invention As described above, according to the ice-making compartment mounting structure of the automatic ice-making machine according to the present invention, as is particularly clear from FIG. 2, the upper portion of the ice-making compartment 10 faces inside the opening of the support member 28, In addition, the pivot 18 that pivots the water tray 16 and the ice-making water tank 22 is also attached to the support member 2.
As a result, the ice making mechanism section 36 occupies a smaller proportion of the space of the ice making machine main body 42. Therefore, if the models have the same ice making capacity, the size of the ice maker casing can be reduced and the ice storage capacity of the ice storage can be fully utilized. In addition, the ice making chamber 10 is supported by the supporting member 2.
8, there is no need to use a large number of sleeves 30 and bolts 32 as in the past, so the work can be accomplished easily and quickly, and the number of parts can be reduced to reduce manufacturing costs. . Moreover, the ice making compartment 10 is directly attached to the support member 28.
Since the structure is such that ice making compartment 10 and water tray 1 are placed
Errors in the dimension in the height direction that adversely affect the gap β (FIG. 7) between the two members 6 and 6 are less likely to occur, making it possible to assemble with stable quality. In this regard, directly supporting the water tray 16 on the support member 28 via the pivot 18 also contributes favorably.

Further, when the lid 44 made of the heat insulating material is removed, the top surface of the ice making chamber 10 and the evaporation pipe 14 are immediately exposed, so cleaning these parts can be done extremely easily.
