<< Embodiment >>
A refrigerated storage 1 with an ice maker (hereinafter, simply referred to as “cooling storage”) according to an embodiment will be described with reference to FIGS. 1 to 17. In this embodiment, a commercial cooling storage 1 used in a kitchen such as a hotel or a restaurant is illustrated. The cooling storage 1 can store a relatively large amount of foodstuffs and the like, and is configured to maintain high cooling performance even if the door is frequently opened and closed. The cooling storage 1 is integrally provided with an ice making unit capable of producing and storing ice. The reference numerals F, Rr, L, R, U, and D shown in the drawings represent front (front), rear (back), left, right, top, and bottom when the cooling storage 1 is viewed from the front, respectively. However, these directions are for convenience only and should not be interpreted in a limited way. Further, for a plurality of the same members, one member may be designated with a reference numeral and the reference numerals of the other members may be omitted.

As shown in FIGS. 1 to 4, the cooling storage 1 has a heat insulating box 10 having a substantially rectangular cuboid shape as a whole, and the heat insulating box 10 is supported by the legs 2. The cooling storage 1 in the present embodiment is designed to have a higher height dimension than, for example, a table type (horizontal type) cooling storage. As a result, a large-capacity cooling storage 1 can be obtained with a relatively small installation area. As shown in FIG. 2, the heat insulating box body 10 is roughly composed mainly of a storage main body 11 having an opening on one front surface, and the storage main body 11 is one outer box 12 made of stainless steel plate. Two inner boxes 13A and 13B, such as stainless steel plates, are housed inside the box with a space between the left and right sides. The gap between the outer box 12 and the inner boxes 13A and 13B and between the two inner boxes 13A and 13B is filled with a heat insulating material 14 made of a foamed resin such as urethane foam. Further, in the inner box 13B on the right side, a heat insulating wall 15 having a heat insulating material filled therein is fixed near the center in the vertical direction, and the heat insulating wall 15 causes the inner box 13B on the right side to move up and down. It is divided into two rooms 13B1 and 13B2. As a result, three rooms (inner box 13A, rooms 13B1, 13B2) that open toward the front are defined inside the storage main body 11.

Here, as shown in FIG. 1, a left-opening type heat insulating door 16A, 16C is attached to the opening of the inner box 13A on the left side, one for the upper portion and one for the lower portion. In this way, the refrigerating chamber 17A is configured by closing the opening of the inner box 13A on the left side with the heat insulating doors 16A and 16C. Further, in the inner box 13B on the right side, a right-opening type heat insulating door 16B is attached to the opening of the upper room 13B1. By closing the opening of the room 13B1 with the heat insulating door 16B, the freezing room 17B is configured. The refrigerating chamber 17A and the freezing chamber 17B are examples of storage chambers in the present technique. The cooling devices 20A and 20B (an example of the first cooling device) for cooling the refrigerating chamber 17A and the freezing chamber 17B will be described later. On the back surface of the door facing the heat insulating box 10 when the heat insulating doors 16A to 16C are closed, a magnetic packing (not shown) is attached in a frame shape at the peripheral edge thereof. As a result, when the heat insulating doors 16A to 16C are closed, the magnetic packing is interposed between the heat insulating doors 16A to 16C and the opening edges of the inner box 13A and the room 13B1. Further, a magnetic packing is arranged between the upper and lower heat insulating doors 16A and 16C so as to be located between the heat insulating doors 16A and 16C in the vertical direction. By providing the heat insulating doors 16A to 16C with magnetic packing in this way, the airtightness of the refrigerating chamber 17A and the freezing chamber 17B is ensured.

Of the inner box 13B on the right side, the room 13B2 partitioned below by the heat insulating wall 15 corresponds to the ice making chamber main body 50 in the present technique. For example, as shown in FIG. 2, the ice making unit 18 is provided in the ice making chamber main body. Be housed. The ice making unit 18 is generally composed of a cooling device 20 (an example of a second cooling device in the present technique), an ice making section 30, and an ice storage section 40. In the ice making unit 18, the ice making plates 31A and 31B of the ice making unit 30 are cooled by the cooling device 20, so that an ice making place is prepared on the inner surface of the ice making plates 31A and 31B. The ice produced in the ice making section 30 is stored in the ice storage section 40. Hereinafter, each component and its installation mode will be described.

First, as shown in FIGS. 2 and 4, the ice making chamber main body 50 has a box shape that opens forward, and has a right side wall portion 50R, a left side wall portion 50L, and a ceiling wall portion 50U ( It has a heat insulating wall (corresponding to the heat insulating wall 15), a bottom wall portion 50D constituting the bottom surface, and a back wall portion 50B constituting the back surface (an example of the back wall portion of the ice making chamber). The ice making chamber main body 50 is vertically divided into an upper non-cooling area A1 and a lower cooling area A2 by a slide substrate mechanism 51 fixed substantially horizontally near the center in the vertical direction.

As shown in FIGS. 3 to 5, in the back wall portion 50B, the portion corresponding to the rear of the non-cooling area A1 is provided with an exhaust port 50E1 that penetrates the back wall portion 50B in the thickness direction. The exhaust port 50E1 also serves as an inspection port, and normally, a lid member 50EA in which a plurality of narrow elongated holes are arranged is attached by screwing or the like. Further, in the back wall portion 50B, below the exhaust port 50E1, the outer box 12 can be partially attached / detached from the exhaust port 50E1 to the lower end. The heat insulating material 14 located below the exhaust port 50E1 has its rear surface removed to the lower end, and the thickness of the heat insulating material 14 is reduced. As a result, a gap 50E2 is formed between the outer box 12 and the heat insulating material 14 on the back wall portion 50B below the exhaust port 50E1. Further, the bottom wall surface of the exhaust port 50E1 is provided with an opening 50E3 that communicates the gap 50E2 with the exhaust port 50E1. As a result, for example, even when the cooling storage 1 is installed with the back surface close to the wall surface of the building, the exhaust ports 50E1, the openings 50E3, and the voids 50E2 function as ducts, and the exhaust from the non-cooling area A1 is discharged from the heat insulating box body 10. It is possible to flow below.

As shown in FIGS. 6 and 7, the slide board mechanism 51 is roughly composed of a slide board 52, a front frame 53, and a frame plate 54. The slide substrate 52 has a substantially rectangular box plate shape made of a stainless steel plate, and is filled with a heat insulating material. Flange portions 52A extend along the upper surface on the four peripheral edges of the slide substrate 52. The front frame 53 has a prismatic length extending over the left and right side wall portions 50L and 50R, and is fixed to the flange portion 52A in front of the slide substrate 52 from below. The frame plate 54 has a U-shape and is fixed to the left and right side wall portions 50L and 50R and the back wall portion 50B so that the left and right and rear flange portions 52A of the slide substrate 52 can be supported from below. It is configured. The slide substrate 52 is configured to be slidable back and forth on the frame plate 54, and by pulling out the slide substrate 52 forward, the cooling device 20 and the ice making section 30 described later mounted on the slide substrate 52. Maintenance can be done easily.

Further, behind the frame plate 54, a hook 54B having a substantially Z-shaped cross section is fixed so as to stand up from the frame plate 54 and extend forward. When the slide board 52 is housed in the rear, the flange portion 52A of the slide board 52 is inserted between the hook 54B and the frame plate 54, and is suppressed from above by the hook 54B. With such a hook 54B, the position of the slide substrate 52 in the front-rear direction can be positioned at a fixed position. Further, in a state where the slide board 52 is housed in the rear, the front frame 53 can be fixed to the brackets 55 provided on the left and right side wall portions 50L and 50R with fastening members such as screws, and the front frame 53 and the bracket. The slide board 52 can be pulled out forward by releasing the fixing with the 55. A sealing tape 54A is attached to the side surface of the frame plate 54 facing the center side of the ice making chamber main body 50 to enhance the heat shielding property between the frame plate 54 and the slide substrate 52.

The slide substrate 52 supports the ice making section 30 and the cooling device 20. An opening 52B for fitting a part of the ice making portion 30 is provided near the center of the slide substrate 52 in the front-rear direction, and the ice making portion 30 is supported on the peripheral edge of the opening 52B and is in front of the ice making portion 30. The cooling device 20 is placed in the space behind. First, the cooling device 20 will be described.

The cooling device 20 is a heat exchanger having the inside of the heat transfer tube as a refrigerant flow path, and is arranged in the non-cooling area A1 by being placed on the slide substrate 52. For example, as shown in FIG. 8, the cooling device 20 includes a compressor 21, a condenser 22, an expansion valve 23 (capillary tube), and an evaporation pipe 24 (evaporator), which are provided by a refrigerant pipe 26. It is connected. The compressor 21 is arranged behind the ice making section 30 (cover member 56) and compresses the refrigerant gas. The condenser 22 and the fan 25 are arranged in front of the ice making section 30 (cover member 56), and the compressed refrigerant gas is liquefied by being cooled by the air blown by the fan 25 in the condenser 22. The expansion valve 23 expands the liquefied refrigerant. The evaporation pipe 24 penetrates into the cover member 56 and is arranged between the ice making plates 31A and 31B, and the liquefied refrigerant expanded by the expansion valve 23 is vaporized to cool the ice making plates 31A and 31B. .. As described above, the compressor 21, the condenser 22, the expansion valve 23, the evaporation pipe 24, and the refrigerant pipe 26 constitute a known steam compression type refrigeration cycle to cool the ice plates 31A and 31B.

As shown in FIG. 8, the cooling device 20 is provided in the bypass pipe 23A connecting the refrigerant pipe 26 for sending the refrigerant gas (hot gas) compressed by the compressor 21 and the evaporation pipe 24, and the bypass pipe 23A. A hot gas valve 27, which is a generated electromagnetic valve, is provided. By opening the hot gas valve 27, the refrigerant gas (hot gas) can be supplied from the compressor 21 to the evaporation pipe 24 to heat the evaporation pipe 24. Further, the condenser 22 is configured so that the lid member 28 can be mounted in front of the condenser 22. The lid member 28 is configured to be able to cover the opening surrounded by the front frame 53 of the slide substrate mechanism 51, the left and right side wall portions 50L and 50R, and the top wall portion 50U among the openings of the ice making chamber main body 50. There is. On the right side of the condenser 22, a control device 70 for controlling various operations of the cooling device 20 is provided.

Next, the structure of the ice making section 30 will be described. As shown in FIGS. 9 to 12 and the like, the ice making unit 30 is a flow-down type ice making device that freezes the water flowing down the plate surface to generate ice. The ice making section 30 roughly includes two ice making plates 31A and 31B, a sprinkling pipe 32 and a sprinkling guide 32A for sprinkling ice making water on the ice making plates 31A and 31B, and ice removal water for melting the produced ice. It is provided with an ice removing pipe 33 for supplying ice, a water storage tank 34 for storing ice-making water, and a pump device 35 for sending the water in the water storage tank 34 to the sprinkling pipe 32. The pump device 35 includes, for example, a pump motor capable of changing the rotation speed. Most of these ice making portions 30 are arranged above the slide substrate 52, but the portions arranged above the slide substrate 52 are covered with the heat insulating cover member 56. With such a configuration, the lower part of the slide substrate 52 and the cover member 56 is insulated (thermally shielded) from the upper part of the slide substrate 52 and the cover member 56. That is, more specifically, the upper part of the slide board 52 and the cover member 56 is the non-cooling area A1, and the lower part of the slide board 52 and the cover member 56 is the cooling area A2.

In the ice making section 30, the two ice making plates 31A and 31B face each other, and are arranged above the opening 52B in a substantially vertical posture so that the plate surfaces are orthogonal to each other in the front-rear direction. The non-opposing outer surfaces of the ice-making plates 31A and 31B are ice-making surfaces, and a plurality of protrusions 31C having a V-shaped cross section are extended in parallel along the vertical direction on the ice-making surfaces. 31C partitions the ice making surface laterally at predetermined intervals. Further, a plurality of protrusions 31D are provided between the protrusions 31C so as to be separated in the vertical direction. By these protrusions 31C and 31D, the ice making surface is divided into grid-like ice making regions, and rectangular ice making regions are arranged vertically and horizontally. An evaporative tube 24 (a part of a cooling device 20 described later) formed in a meandering shape is brazed between the pair of ice plates 31A and 31B, and the linear portions of the evaporative tube 24 are arranged vertically. It is arranged so as to extend horizontally between the protrusions 31D.

A sprinkling pipe 32, a sprinkling guide 32A, and an ice removing pipe 33 are arranged on the ice making plates 31A and 31B. The sprinkler pipe 32 is connected to a water supply pipe 34A provided with a pump device 35, and the other end of the water supply pipe 34A is arranged at a predetermined depth position in the water storage tank 34. As a result, by driving the pump device 35, the ice-making water stored in the water storage tank 34 is sent to the sprinkler pipe 32 and sprinkled from the sprinkler pipe 32. The sprinkled ice-making water is sent to the ice-making surfaces of the ice-making plates 31A and 31B by the sprinkling guide 32A, and flows down the ice-making surface. Further, the deicing pipe 33 is connected to a water pipe 34C that interposeds at a water supply valve 34B, and the water pipe 34C is connected to a water pipe or the like (not shown). As a result, by opening the water supply valve 34B, tap water is supplied to the ice removal pipe 33 and sprinkled from the ice removal pipe 33. The sprinkled tap water is sent to the back surface (opposing surface) of the ice plates 31A and 31B and flows down. The water flowing down the ice making surface and the back surface of the ice making plates 31A and 31B falls from the ice making plates 31A and 31B and is supplied to the water storage tank 34. The ice removing pipe 33 also has a function of warming the ice making plates 31A and 31B from the back side with tap water and a water supply function of supplying tap water to the water storage tank 34.

The water storage tank 34 is arranged below the slide substrate 52. The water storage tank 34 has a substantially L-shaped planar shape and has a box shape with an opening at the upper side. The water storage tanks 34 are arranged in the left-right direction below the ice making plates 31A and 31B so that the water that has flowed down to the ice making plates 31A and 31B and was not used for ice making can be stored in the water storage tank 34 as described above. It has become. The bottom surface of the water storage tank 34 is tilted downward toward the right, and is expanded toward the rear at the right end. A water level sensor 39A capable of detecting the water level of the water storage tank 34 is provided at the right end portion. Further, the pump device 35 is housed in the rear expansion portion, and the other end of the water supply pipe 34A is arranged at a position close to the bottom surface. The wall on the right side of the expansion part is provided with an opening at a predetermined height, and a gutter-shaped flow path for flowing water overflowing from this opening to the outside extends through this opening and the flow path. The overflow gutter 34D that defines the upper limit of the amount of water stored in the water storage tank 34 is configured. The right side wall portion 50R is provided with a drainage pan 37 at a position below the overflow barrier 34D when the slide substrate 52 is housed in the ice making chamber main body 50. Excess water exceeding the overflow barrier 34D is received by the drainage pan 37 in a state where the slide substrate 52 is housed in the ice making chamber main body 50, and is cooled and stored from the drainage port 38 provided in the bottom wall portion 50D through the drainage pipe 37A. It is drained to the outside of.

Further, the sprinkler pipe 32 is arranged at a relatively high position with respect to the pump device 35, and the water supply pipe 34A connecting the pump device 35 and the sprinkler pipe 32 is provided between the pump device 35 and the sprinkler pipe 32. The drainage pipe 35A is branched from the height. The drainage pipe 35A is interposed at the drainage valve 35B, is arranged at a height lower than the branch position, and has other ends extending to the rear of the overflow barrier 34D. During ice making, the pure water component of the water crystallizes and impurities remain in the ice-making water that has not frozen. Therefore, as the ice making progresses, the impurities in the tap water are concentrated in the stored water of the water storage tank 34. In the above configuration, by driving the pump device 35 with the drain valve 35B opened in a timely manner, the stored water containing impurities accumulated in the water storage tank 34 can be sent to the drain pipe 35A and received by the drain pan 37. This allows drainage to the outside of the cooling storage 1. A cube guide 36 is arranged between the ice plates 31A and 31B and the water storage tank 34. As shown in FIG. 11, the cube guide 36 is a slatted member having a plurality of openings (which may be gaps, grooves, and elongated holes), and the upper end of the slatted plate is ice-making plates 31A and 31B. It is formed so that the apex is directly below the drainboard and the slope is downward as it goes back and forth.

In the ice making unit 30 having the above configuration, the control device 70 operates the cooling device 20 to cool the ice making unit 30 to a predetermined ice making temperature, and then drives the pump device 35 to make ice water on the ice making plates 31A and 31B. Let it flow down. At this time, the ice making plates 31A and 31B are most cooled at the portion where the evaporation pipe 24 is in contact with the back surface, and the ice making water freezes around the position where the evaporation pipe 24 is arranged during the flow. As a result, crescent-shaped ice particles are generated in the ice making region. The formation of crescent-shaped ice particles can be grasped by detecting the water level of the water storage tank 34 (that is, the consumption of ice-making water), which decreases with ice making, with the water level sensor 39A. When crescent-shaped ice particles are generated on the ice plates 31A and 31B, the control device 70 opens the hot gas valve 27 to supply hot gas to the evaporation pipe 24 and heats the ice plates 31A and 31B to make ice. The grains are dropped from the ice plates 31A and 31B. The ice that has fallen from the ice plates 31A and 31B slides back and forth on the drainboard-shaped cube guide 36, respectively. On the other hand, the water flowing down from the ice plates 31A and 31B passes through the opening (gap) of the cube guide 36 and is collected in the water storage tank 34. The completion of the fall of ice from the ice making plates 31A and 31B means that the surface temperature of the ice making plates 31A and 31B or the temperature on the outlet side of the evaporation tube 24 melts and drops the ice by the temperature sensor (not shown). It can be confirmed by detecting that the temperature has risen to a sufficient level. Further, an ice storage sensor 39B (see FIG. 13 and the like) for detecting the amount of ice stored in the ice storage unit 40, which will be described later, is provided on the lower surface on the rear side of the slide substrate 52.
