Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for arranging components in a machine room, and more particularly, to maintaining the air permeability in the machine room, minimizing the arrangement volume of components in the machine room, and further improving the machine room. The present invention relates to a component arrangement structure capable of easily performing inspection, repair, replacement, and the like of the component parts.

[0002]

2. Description of the Related Art In a machine room of an ice making machine or the like, a refrigeration mechanism including a compressor, a condenser, a fan motor and the like for supplying a refrigerant or the like to a cooler of the ice making mechanism is housed and arranged. Since each component of the refrigeration mechanism has a large volume and a large weight, its arrangement position and arrangement structure are determined in consideration of various factors. The location of the component is such that the weight of the component parts is large and the ice maker itself is placed as close to the bottom as possible in order to ensure stability during installation. In order to make the ice making room and the ice storage room, which are the main components, large, it is desirable to make the structure as compact as possible.

In the current ice maker, the arrangement position and the arrangement structure can almost completely satisfy the above-mentioned conditions, and the path of the cooling air for air cooling relating to the heat radiation in the machine room, which is also a heat source, is also required. Well considered, the path is not blocked by components in the machine room and the cooling effect is not impaired. Furthermore, the casing that forms the outer shell of the ice maker is configured by arranging an outer panel on the base, and its detachment is easy, and the inspection, repair, and replacement of the refrigeration mechanism in the machine room are efficient, and It can be done quickly. However, the current arrangement position and arrangement structure employed are possible in the components of the refrigeration mechanism described above,
It is pointed out that a problem arises when new components increase.

[0004] The components inside the machine room are supposed to be used in Japan and all operate at the same voltage of 100V. Therefore, when exporting to various foreign countries having different supply power supply voltages, it is necessary to adjust and replace all the components in accordance with the supply voltage. However, if this method is used, it is necessary to use different components for each different supply voltage, and since the same component cannot be used, the manufacturing process is divided and the number of components increases, resulting in an increase in manufacturing cost. . Such a problem can be avoided without increasing the manufacturing cost by using a transformer that converts different supply voltages to the same voltage as in Japan.

[0005]

However, adding the above-described transformer to the components of the refrigeration mechanism changes the conventional arrangement position and arrangement structure.
In addition, since there is no space for disposing the transformer in the conventional case size, it is necessary to increase the space in the machine room. At this time, if the space required for housing the transformer is secured above or below the compressor, the height of the entire housing increases, and the stability of the housing and the components inside the machine room also decreases. On the other hand, when disposing the transformer without changing the height of the housing, the depth or width of the housing must be increased, which requires a large number of installation locations for the housing.

Further, it is conceivable that the flow of cooling air in the machine room is hindered by the increase and arrangement of the components arranged in the machine room, and the problem of cooling in the machine room is pointed out.
Further, in the transformer, opportunities for inspection, adjustment, repair, etc. due to an increase in the number of components, etc. are further increased along with an adjustment opportunity due to a difference in supply voltage, but an outer panel forming a housing covers the machine room integrally. Therefore, it is pointed out that the inspection, repair, adjustment and the like cannot be performed quickly, and the entire outer cover must be removed each time.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks inherent in the prior art, and has been proposed in order to solve the problem in a favorable manner. It is an object of the present invention to provide a component room structure of a machine room that can make the room compact.

[0008]

SUMMARY OF THE INVENTION In order to overcome the above-mentioned problems and achieve the intended object, the present invention provides a component arrangement structure for disposing a refrigeration mechanism and the like in a machine room defined inside a housing.

It is characterized by having done.

An ice storage compartment 14 is defined inside a casing 10 forming an outer shell of the ice making machine, and the outside is provided with a heat insulator 4.
An ice storage 48 covered by 6 is provided, and an ice making mechanism 40 is provided above the ice storage room 14. This ice storage 48
A control mechanism 4 for controlling the operation of the ice making mechanism 40
4 and an ice discharging mechanism 42 for discharging ice blocks stored in the ice storage chamber 14 are provided. The compressor 24 and the transformer 28 are located below the ice storage 48 inside the housing 10.
A machine room 16 for accommodating the refrigeration mechanism 20 having the same is defined, and the base 12 and the back plate 6
A plurality of ventilation holes 22 and 23 are formed in 0. Here, the ice blocks produced by the ice making mechanism 40 are stored in the ice storage chamber 14 and supplied to the user by the ice discharging mechanism 42 as needed.

As shown in FIGS. 2 and 3, a compressor base 30 is disposed on the rear side of the base 12 defining the machine room 16 near the back plate 60, and the compressor base 30 is mounted on the compressor base 30. 24 are mounted and fixed with bolts or the like. As shown in FIG. 5, the compressor base 30 is formed in a U-shape having side plates 64, 64 suspended on left and right sides of an upper plate 62, and leg portions 66 extending outward from lower end edges of the respective side plates 64. The base 12 is fixed to the base 12 with bolts or the like without blocking the bottom hole 22. The upper plate 62 has a plurality of through holes 62a.
Are formed, and a notch 64a is formed in the side plate 64 so as to secure air permeability to the bottom surface vent hole 22 formed in the base 12. The compressor 24 is mounted and fixed to the upper plate 62 of the compressor base 30 without blocking the through holes 62a.

A terminal 26 for supplying power and control signals to the compressor 24 is provided on the front side (the right side in FIG. 2) of the compressor 24. The terminal 26 is covered with a terminal cover 26a on the outside. . Then, the transformer base 3 is placed on the base 12 facing below the terminal cover 26a.
2, a transformer 28 is arranged. That is, as shown in FIG. 6, the transformer table 32 basically includes the upper plate 68 and the pair of side plates 70 and 70, similarly to the compressor table 30.
And the legs 72, 72, and are fixed to the base 12 without blocking the bottom surface ventilation hole 22. The height of the transformer table 32 is
And the transformer 28 mounted and fixed on the upper surface of the transformer base 32 does not interfere with the terminal cover 26a. The transformer 28 and the terminal cover 26a partially overlap with each other vertically, and the transformer 2
The length in the front-rear direction of the ice making machine (the machine room 16), which increases when the 8 is provided, can be minimized.

The side plates 70,
A required gap 74 is defined between the front and rear ends where the base 70 is not formed and the base 12, and through this gap 74, sufficient air permeability to the bottom air hole 22 formed in the base 12 is ensured. It is composed.

A bottom air hole 2 formed in the base 12
The rear ventilation holes 23 formed in the rear plate 2 and the rear plate 60 communicate the outside and the machine room 16, respectively, and function to take in or send out the outside air into the machine room 16 as the cooling air 4. . That is, by driving the fan motor 34 disposed above the compressor 24, the cooling air 4 sucked into the machine room 16 from the bottom surface ventilation hole 22 contacts the compressor 24 and the transformer 28 to cool it. The cooling air 4 after the heat exchange is blown out to the outside through the rear ventilation holes 23.

As shown in FIG. 4, the outer panel 18 constituting the housing 10 includes a cabinet 50 integrally covering the upper part and left and right side surfaces of the ice storage 48, a front panel 52 covering the front surface thereof, and the cabinet 50. A pair of left and right side panels 5 covering from the lower end of 50 to the base 12

That is, the cabinet 50 and the front panel 52 that cover the ice storage 48 and the like, and the side panel 54 and the under cover 56 that cover the machine room 16 defined under the cabinet 50 are completely independent. When inspecting, repairing, and replacing the transformer 28, which is a component inside, the side panel 54 without removing the entire outer panel 18.
Alternatively, it can be easily dealt with by removing the under cover 56. In FIG. 4, reference numeral 58 denotes
Shown is a filter member that is detachably disposed on the lower surface of the base 12 and covers the bottom surface vent hole 22.

[0015]

Next, the operation of the machine room component arrangement structure according to the embodiment will be described. The transformer 28 disposed in the machine room 16 is disposed below the terminal cover 26a of the compressor 24 disposed via the compressor stand 30 so that a part thereof vertically overlaps with a required vertical difference. ing. Therefore, in the case where the transformer 28 is provided for the foreign country in which the transformer 28 is provided in addition to the components of the conventional (Japanese domestic) refrigeration mechanism 20, the size change of the housing 10 is extremely small by adding the transformer 28. Can be suppressed. Further, since the compressor 24 and the transformer 28 are arranged in the lower part of the machine room 16, the stability of the ice making machine can be ensured.

The compressor 24 and the transformer 2
The compressor 24 and the transformer 28 are connected to the bottom vent 22 functioning as an inlet of the cooling air 4 for cooling the cooling air 8.
Are arranged in a state where air permeability is ensured via the compressor table 30 and the transformer table 32 as shown in FIGS. Therefore, even in the configuration in which the transformer 28 is increased as in the embodiment, the air permeability in the machine room 16 is ensured, and the cooling of the refrigeration mechanism 20 can be efficiently performed.

Further, as described above, the cabinet 50 and the front panel 52 for covering the ice storage 48 and the like, and the side panel 54 for covering the machine room 16 defined under the cabinet 50 and the front panel 52.
And the under cover 56 is completely independent of the side panel 54 or the under cover without removing the entire outer panel 18 when inspecting, repairing, or replacing the transformer 28 or the like, which is a component in the machine room 16. This can be easily dealt with by removing 56.
Therefore, the inspection, repair and replacement of the components in the machine room 16 can be performed easily and in a short time.

In the embodiment, the case where the transformer 28 is arranged on the base 12 via the transformer table 32 has been described. However, the transformer 28 may be arranged directly on the base 12. In this case, the height of the compressor stand 30 can be set low, and the height of the machine room 16 can be kept low.

[0019]

As described above, according to the component room structure of the machine room according to the present invention, by disposing the transformer below the terminal cover that covers the terminals of the compressor, the location of the components in the machine room can be reduced. Effective utilization can be achieved. That is, when a newly increasing transformer is provided, it can be dealt with only by making the machine room as large as possible. In addition, since the heavy compressor and transformer are arranged at the bottom in the machine room, the center of gravity of the ice maker and the like can be maintained at a low position, and the effect of obtaining stability can be obtained.

In addition, a compressor table and a transformer table are installed at a place where the compressor and the transformer are installed,
By mounting a compressor and a transformer thereon, the ventilation of the cooling air for cooling the machine room is ensured. Moreover, by providing the compressor stand with a vent hole and a notch, the air permeability can be made more effective.

With regard to the outer panel constituting the housing, the side panel covering the side surface of the machine room is formed as a separate body, and the side panel can be attached and detached independently. It has the advantage that inspection, repair and replacement of components can be easily performed.
