[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention particularly relates to improvement of a stack-on type automatic ice maker.

[0002]

[Prior Art]

 The stack-on type fountain-type automatic ice machine is composed of an upper ice-making mechanism and a freezer machine room, and a lower ice storage.The ice pieces produced intermittently in the ice-making mechanism drop into the sequential ice storage. Although it is stored, the ice-making mechanism keeps insects and debris from entering from the outside, and keeps the inside temperature almost sealed to prevent the internal temperature from rising easily. Since tap water is mostly used as ice-making water and cooling water for this purpose, chlorine contained in the ice-making water and cooling water is used as chlorine gas when the ice-making water is ejected to the ice-making cell or flows down to the drain tray. As a result, the chlorine gas was released from the water, and conventionally, this chlorine gas stagnates inside the ice making mechanism and the ice storage communicating with it. For this reason, chlorine adheres to the surface of the ice pieces stored in the ice storage, causing an unpleasant chlorine odor when the ice pieces are used for eating and drinking, or driving parts of the ice making mechanism and various parts. There was a problem that rust was easily induced on the fixing screws of the.

[0003]

[Problems to be solved by the device]

 The present invention is intended to prevent chlorine gas from accumulating in the ice-making mechanism of an automatic ice-making machine or the like to prevent odor from adhering to the produced ice pieces and rusting of each portion.

[0004]

[Means for Solving the Problems]

 To achieve this object, the automatic ice making machine according to the present invention is provided with an opening on the outer wall of the ice making mechanism, and a fan is installed at or near the opening, and the ice making mechanism is driven by the fan. It is configured to be exhausted from the inside through the opening.

The automatic ice making machine according to the present invention has an opening provided on the outer wall of the ice making mechanism, a fan installed at or near the opening, and a damper attached to the opening. When the fan is driven, the damper is opened so that the air is exhausted from the inside of the ice making mechanism section through the opening.

Further, in the automatic ice maker according to the present invention, an exhaust port is provided in a shielding plate that separates the ice making mechanism unit and the freezer machine room, and the condenser fan installed in the freezer machine room is driven to operate the above. The inside of the ice making mechanism is configured to be exhausted through the exhaust port.

[0007]

[Action]

 That is, since the fan is driven to discharge air from the inside of the ice making mechanism through the opening of the outer wall or the exhaust port of the shield plate for the freezer machine room, chlorine gas generated from ice making water and cooling water of the automatic ice making machine It is not positively and reliably discharged outward from the ice making mechanism, etc., and does not stay inside the ice making mechanism. Therefore, it is possible to avoid the chlorine odor of the ice pieces produced by the automatic ice making machine, and at the same time, the automatic ice making machine Rust inside can be easily suppressed.

【Example】

 Hereinafter, embodiments of the present invention shown in the drawings will be specifically described. 1 to 3, a stack-on type fountain type automatic ice maker 1 includes an upper ice making mechanism 2 and a freezer machine room 3 and a lower ice storage 4, and an ice making water tank 5 in the ice making mechanism 2. The ice-making water sucked up by the pump 6 from the pump 6 and ejected to the ice-making cell 7 gradually forms ice pieces in the ice-making cell 7 cooled by the refrigerant, and the produced ice pieces 8 are ice-making at the time of deicing shown in FIG. It falls according to the tilt of the water tank 5 and is stored in the ice storage 4.

On the other hand, residual water in the ice making water tank 5, dew condensation water at various parts in the ice making mechanism 2, drainage from the cooling water passage 9 and the like are collected in a drain tray 10 and discharged to the outside of the machine. An opening 21 is formed in the outer side wall 20 of the ice making mechanism 2, a fan 23 is installed in the opening 21 by a cross-shaped stay 22 fixed to the periphery of the opening 21, and a resin filter 24 having a fine mesh 24 is provided. Is attached by a support frame 25 so as to face the outside of the opening 21 and cover the opening 21. The fan 23 is intermittently driven at an appropriate time interval by a timer (not shown), and is driven by the fan 23 to be exhausted from inside the ice making mechanism 2 and the ice storage 4 through the opening 21 and the filter 24.

Therefore, even if chlorine gas is generated from ice-making water, cooling water, etc. in the ice-making mechanism unit 2, the air in the automatic ice-making machine 1 is positively discharged to the outside by the fan 23 and the automatic ice-making machine 1 Since chlorine gas does not stay inside, the ice pieces 8 stored in the ice storage 4 do not have a chlorine odor, and it is possible to provide ice pieces that are always odorless and clean and suitable for eating and drinking. At the same time, rusting of chlorine in each part of the automatic ice maker 1 is suppressed to prolong the service life of the parts, and the automatic ice maker 1 can be used for a long time.

Further, since the opening 21 of the outer wall 20 is covered with the filter 24, insects and dust are prevented from entering the ice making mechanism section 2 from the outside through the opening 21 and the filter 24 is provided. Since the elastic member can be easily attached to and detached from the support frame 25 by utilizing the bending due to its elasticity, the filter 24 can be cleaned very easily.

Further, since the outer wall 20 of the ice making mechanism 2 is generally structured to be easily removed, it is easy to clean, repair, or replace the fan 23 fixed to the outer wall 20. When exhaust by the fan 23 is unnecessary, the outer wall without the opening 21 can be easily replaced. Since the fan 23 is driven intermittently as appropriate, the temperature inside the ice making mechanism part 2 does not rise extremely even if the opening 21 is formed in the outer wall 20, so that the ice making function of the automatic ice making machine 1 is improved. There is no particular loss.

Next, in the embodiment shown in FIGS. 4 to 6, the same reference numerals as those in the above embodiment represent the same parts, but in this embodiment, they are formed on the outer wall 20 of the ice making mechanism 2. Inside the opening 21, a fan 31 is installed close to the opening 21 by a cross-shaped stay 30 fixed to the periphery of the opening 21, and a hinge 33 at the upper side allows a light damper 33 to swing so as to swing. The fan 31 is intermittently driven at appropriate time intervals as in the case of the above-described embodiment, and when the fan 31 is driven, the damper 33 is driven by the wind pressure thereof as shown by the chain double-dashed line in FIG. Since the opening 21 is opened by tilting to the right, the fan 31 positively discharges chlorine gas generated from the ice making mechanism 2 and the ice storage 4 through the opening 21 and generated from the ice making water and the cooling water in the ice making mechanism 2. Outside Since it is not discharged to the inside and chlorine gas does not stay inside, it is possible to provide odorless ice pieces 8 at all times, and suppress the rusting of each part inside the automatic ice making machine 1 to use the automatic ice making machine 1 for a long time In addition, since the wind pressure disappears when the fan 31 stops rotating, the damper 33 closes the opening 21 again by its own weight, which prevents insects and dust from entering the ice making mechanism 2 through the opening 21.

It should be noted that a magnet with a weak magnetic force is attached to one of the lower edge of the opening 21 and the inside of the lower end of the damper 33 facing the opening 21, and a small iron plate is attached to the other, so that the damper 33 flaps when it is closed. A link or lever that operates in synchronization with the driving of the fan 31 or a protruding member is appropriately provided between the damper 33 and the peripheral edge of the opening 21 to prevent the link or the like from operating when the fan 31 is driven. Therefore, the damper 33 can surely open the opening 21. It is also possible to install the structure of the hinge 32 and the damper 33 on the outer surface of the support frame 25 in the above embodiment.

In the embodiment shown in FIGS. 7 to 9, the same reference numerals as those in the above-mentioned embodiments respectively represent the same parts, but in this embodiment, the ice making mechanism part 2 and the freezer machine room 3 are partitioned. An exhaust port 41 is provided above the rear side of the shielding plate 40, and an exhaust duct 42 having one end screwed to the peripheral edge of the exhaust port 41 so as to communicate with the exhaust port 41 once stands up inside the refrigeration machine room 3. The other end, which is bent in an inverted U shape and extends to the vicinity of the condenser fan 43, opens toward the condenser fan 43.

Since the condenser fan 43 is intermittently driven so as to rotate during ice making in the ice making mechanism unit 2 and stop during ice making, when the condenser fan 43 is driven, the above-mentioned other conditions of the exhaust duct 42 Due to the negative pressure generated at the end, the chlorine gas generated from the ice making mechanism 2 and the ice storage 4 through the exhaust duct 42 and generated from the ice making water and cooling water in the ice making mechanism 2 is also positively generated by the compressor fan 43. Since chlorine gas is not discharged internally and chlorine gas does not stay inside, it is possible to always provide odorless ice pieces 8 as in each of the above-mentioned embodiments, and suppress rusting of each part in the automatic ice maker 1. Enables long-term use of the automatic ice making machine 1.

When the condenser fan 43 stops rotating, the bent portion 44 of the exhaust duct 42 becomes an air trap, which makes it difficult for hot air to flow into the ice making mechanism portion 2 from the refrigeration machine room 3 side. The ice-making function of the automatic ice-making machine 1 is not hindered. If the exhaust duct 42 is unnecessary, remove the fixing screw and take out the exhaust duct 42, then fix the lid to the exhaust port 41 using the fixing screw or exhaust the blind lid made of resin. It only needs to be elastically fitted into the mouth 41, and the work is extremely simple.

The embodiment shown in FIGS. 10 and 11 is a modification of the above-mentioned embodiment, and in the shielding plate 40 partitioning the ice making mechanism section 2 and the freezer machine room 3, a position relatively close to the condenser fan 43. An exhaust hole 50 is provided in the exhaust hole 50, and the negative pressure generated when the condenser fan 43 is driven is used to exhaust air from the inside of the ice making mechanism 2 and the ice storage 4 through the exhaust hole 50. The effect similar to the example can be obtained.
