Description
Technical Field
The present invention relates to a rapid cooling device for producing shaved ice using an ice layer forming drum.
Background
The basic principle of the present invention is described in patent document 1. The basic principle comprises the following parts: a water supply member for supplying water to the water receiving tool; a rapid cooling member having a strip-shaped double-layered tube having the same core; a refrigerant supplied from the rapid cooling member; an ice layer forming drum that forms a film-like ice layer on an outer peripheral surface thereof by the refrigerant while rotating water supplied from the water supply member like a "water wheel"; and a cutting blade provided so as to intersect the outer peripheral surface of the ice layer forming drum and configured to continuously cut the film-like ice layer.
Accordingly, an object of the invention described in patent document 1 is to provide a rapid cooling shaved ice producing apparatus which is capable of forming a film-like ice layer by supplying water to the outer peripheral surface of a cooling cylinder from above via a water supply pipe 28b and a water supply receiver 28a, and which is efficient and simple in structure.
Further, an aspect of the present invention is characterized by including: a cooling cylinder 21 which rotates while maintaining an outer peripheral surface at a temperature of not more than a freezing point and forms an ice layer having a predetermined thickness on the outer peripheral surface thereof; an ice shaving blade 29 formed on the outer peripheral surface of the cooling cylinder and provided so as to be substantially in contact with the outer peripheral surface of the cooling cylinder; and a water supply member 28 including a water supply kit (receiver) 28a in which the edge portions of the both side surface portions and the edge portion of the front surface portion are substantially in contact with the outer peripheral surface of the cooling cylinder, and a water supply pipe 28b (see fig. 3) for supplying water to a space formed by the water supply kit 28a and the outer peripheral surface of the cooling cylinder 21. The reference numerals are those in patent document 1.
The invention of patent document 1 has an advantage that the film-like ice layer can be formed instantaneously and substantially uniformly, but has the following problems.
(a) The cooling cylinder 21, the ice blade 29, the water supply member 28, and the like cannot be easily attached to the housing because of the reason that the bearing members are attached to the left and right side walls of the elongated housing, the cooling cylinder 21 is provided inside the housing via the bearing members, the ice blade 29 is provided inside the housing in an inclined shape, and the water supply member 28 having a complicated structure is disposed near the upper side of the cooling cylinder 21 in order to supply water from the upper side of the outer peripheral surface of the cooling cylinder 21. Therefore, the production is troublesome. Also, the space portion of the front wall of the housing cannot be effectively utilized.
(b) For example, since a storage container for receiving "snow-like shaved ice" shaved by the ice shaving blade 29 is provided inside the housing, the storage container 30 is troublesome to pick and place, and the entire apparatus is large in size.
(c) The snow-like shaved ice drops directly into the storage container and accumulates in a specific portion of the storage container. Further, the storage container 30 cannot be moved to a desired position manually or electrically during the rotation of the cooling drum 21.
(d) There is no description about a structure for preventing the gas rapidly vaporized in the internal space of the cooling cylinder 21 from leaking to the outside. Further, since there is no packing for maintaining airtightness, a powerful compressor cannot be used.
(e) In addition, it is difficult to control the water not to overflow from the water supply kit 28a, and there is no technical problem or technical solution of using soft water and safe water for ice shaving.

Technical problem to be solved by the invention
A first object of the present invention is to effectively utilize the advantages of the invention of patent document 1 and to effectively utilize the space portion for mounting between the left and right projecting support portions provided on the front surface of the housing, thereby enabling easy assembly of the components such as the ice layer forming drum, the cutting blade, the ice shaving guide plate, and the like. This makes it possible to achieve an efficient manufacturing operation and a small-sized device. At the same time, a container for receiving snow-like shaved ice sliding down from the ice shaving guide plate is arbitrarily placed in a space below the ice shaving guide plate on the front surface of the housing, and is freely displaced by, for example, a hand or a turntable. Further, the gasified gas which is injected into the inner space of the ice layer forming drum and which has lost the cooling temperature is prevented from leaking to the outside.
A second object is to sufficiently maintain "airtightness" without allowing gas flowing into the inner space of the ice layer forming drum to easily leak to the outside even if the pressure of a compressor constituting the cooling means is increased. Further, according to the embodiment, the sealing material is excellent in durability.
The third object is to prevent the water W for ice shaving flowing out from the introduction path having the opening/closing valve from "overflowing" or scattering from the water storage tray as much as possible.
The fourth object is to produce "non-sticky" (not immediately melted) and soft "snow-like shaved ice using soft water for safe ice shaving.
In addition, the object of not dissipating the cooling heat of the ice layer forming drum through a bearing, making the arc-shaped lower side of the ice layer forming drum always bubble in the water for ice shaving even if the water storage tray is thinned, not adhering dust to the ice layer forming drum, and freely taking and putting the water storage tray with a shallow bottom is dealt with by the dependent means.
Technical solution for solving technical problem
The present invention provides a rapid cooling ice shaving manufacturing device, comprising: a housing having left and right protruding support portions; an ice layer forming drum which is horizontally disposed in the installation space portion between the protruding support portions via left and right bearing members and which is rotated by a driving force of a driving motor; a water storage tray having an open upper end, disposed horizontally below the ice layer forming drum, and temporarily receiving "water for ice shaving" from a water supply unit provided in the housing through a water introduction path; a cutting blade which is supported by the left and right projecting support portions in a horizontal state so as to be substantially in contact with the front side of the ice layer forming drum, and cuts off a film-like ice layer formed on the outer peripheral surface of the ice layer forming drum; a guide plate fixedly provided to the left and right projecting support portions so as to guide the snow-like shaved ice cut by the cutting blade in a predetermined direction; a cylindrical protrusion rotatably supported by one of the left and right bearing members is provided on one side wall of the ice layer forming drum, an inner and outer elongated cylindrical tube constituting a rapid cooling member is concentrically inserted into the cylindrical protrusion, and at least a first sealing material is provided between an outer peripheral surface of the outer elongated cylindrical tube and an inner peripheral surface of an annular recess formed in the cylindrical protrusion (claim 1). The effects of the present invention will be described later.
In addition to the above configuration, a second sealing material is disposed in the axial direction of the elongated cylindrical tube together with the first sealing material, and one side surface of the second sealing material is in pressure contact with the other side surface of the first sealing material in a close contact state (claim 2). According to this configuration, even if the pressure of the compressor constituting the rapid cooling means is increased, the "airtightness" can be sufficiently maintained so that the gas flowing into the internal space of the ice layer forming drum does not leak to the outside.
Further, at least the first sealing member and the second sealing member are members for sealing the packing, and opposite side walls of each other are pressed against each other by a packing presser having a plurality of fixing members screwed into the cylindrical protrusion (claim 3). According to this configuration, the sealing strength in the radial direction with respect to the outer elongated cylindrical pipe is improved, and the sealing material is less likely to be broken, so that the durability of the device can be maintained.
Further, an automatic or manual opening/closing valve is provided in the water introduction path, and a flow rate control member is connected to the opening/closing valve toward the water storage tray, and an opening at an upper end of the flow rate control member has a large diameter and a control opening at a lower end thereof has a smaller diameter than the opening, so that the water for ice shaving can gradually flow toward the water storage tray (claim 4).
According to this configuration, the amount of "water for ice shaving" flowing out from the flow rate control member can be made to substantially correspond to the thickness and amount of the film-like ice layer formed on the outer peripheral surface of the ice layer forming drum. Further, the water for ice shaving flowing out of the introduction path having the opening/closing valve can be prevented from "overflowing" or scattering from the water storage tray as much as possible.
The water supply unit of the casing temporarily stores "water for ice shaving" softened by the ion exchange resin unit and from which the bacteria are removed by the filtration processing unit, and the water supply unit is further connected to a water introduction path having an on-off valve (claim 5). According to this configuration, soft snow-like shaved ice which is "delicious and safe" and does not immediately melt can be produced.
Further, the water storage tray having an upper end opening is characterized by having a flat portion for receiving "water for ice shaving" and a shallow recess portion continuous with the flat portion (claim 6). According to this configuration, the lower portion of the ice layer forming drum can be always in contact with the water for ice shaving flowing into the shallow recess portion like a waterwheel. In addition, even if the water storage tray is thin, the ice layer forms the arc-shaped lower side of the drum and can be always soaked in the water for ice shaving.
Further, the left and right bearing members are molded into a cylindrical body having a flange portion using a synthetic resin material (claim 7). According to this configuration, the heat of the ice layer forming drum can be dissipated without passing through the bearing.
Further, a cover for covering the exposed outer peripheral surface and the cutting blade of the ice layer forming drum is provided in the space for attachment of the protruding support portion (claim 8). According to this configuration, dirt can be prevented from adhering to the ice layer forming drum.
Further, the outer elongated cylindrical tube is configured to inject a refrigerant, which is pressure-fed from a compressor housed in a casing, into an internal space of the ice layer formation drum in a vaporized state through a small injection hole, and the inner elongated cylindrical tube is configured to receive a vaporized gas, which is injected into the internal space and has lost a cooling temperature, through a suction port, and to return the vaporized gas to the compressor housed in the casing (claim 9). According to this configuration, the refrigerant can be effectively used.
ADVANTAGEOUS EFFECTS OF INVENTION
The present invention can effectively utilize the basic principle and the advantages of the invention described in patent document 1. Further, the space for installation between the left and right projecting support portions provided on the front surface of the housing can be effectively utilized, and the components such as the ice layer forming drum, the cutting blade, and the ice shaving guide plate can be easily installed on the left and right projecting support portions. This makes it possible to increase the efficiency of the manufacturing operation and to reduce the size of the device. At the same time, a container for receiving snow-like shaved ice sliding down from the ice shaving guide plate can be arbitrarily placed in a space below the ice shaving guide plate on the front surface of the housing, and can be freely displaced by hand or using a turntable, for example. Further, the evaporated gas that has been ejected into the internal space of the ice layer forming drum and has lost the cooling temperature can be prevented from leaking to the outside. According to the embodiment, since the water W for ice shaving is used, it is possible to produce "delicious and safe" soft snow-like shaved ice that does not immediately melt.

Detailed Description
First, the structure of the casing 1 of the rapid cooling shaved ice manufacturing apparatus (hereinafter referred to as "apparatus X") will be briefly described with reference to fig. 1 to 4. Referring to fig. 1 of the front view and fig. 2 of the right side view, the housing 1 is constituted by a box-like first housing portion 2 corresponding to a lower portion, and a box-like second housing portion 3 provided integrally above the first housing portion.
The second housing portion 3 is composed of a rear housing portion 3a on the upper surface of which the water supply portion 6 can be provided, and a pair of left and right protruding support portions 3b extending horizontally from both left and right end portions of the rear housing portion. The left and right projecting support portions 3b project from the front wall 2a of the first housing portion 2 in a box-like manner by a predetermined amount, and an installation space portion 4 that opens in a state where the upper, lower, and front portions communicate with each other exists between the left and right projecting support portions 3 b. The mounting space portion 4 is a rectangular parallelepiped component mounting space, for example.
Fig. 3 shows a hollow cylindrical ice layer forming drum 5 which is horizontally provided between the left and right projecting support portions 3b via left and right bearing members 7 and is rotated by a driving force of a driving motor 21 described later, and a water supply portion (a water storage tank having a lid, a water tank, etc.) 6 which is freely provided on the upper surface of the rear housing portion 3a and receives water from a water source 60 described later.
A first switch for rotating the drive motor forward and a second switch (not shown) for rotating the drive motor backward are provided on the front surface of either of the left and right protruding support portions 3 b. A control unit for applying control signals for forward rotation and reverse rotation to the drive motor, a storage unit in which a program for controlling the drive motor is recorded, a timer for counting a cutting time, a water level sensing member, an electromagnetic valve, a compressor, and the like (omitted) are appropriately disposed in the housing 1.

Next, fig. 4 shows the main components seen from the external appearance in a state where the right side wall of the housing 1 is removed. The lower box-shaped first housing portion 2 houses a compressor (virtual line) 12 and a heat exchange member (solid line) 13, which constitute a rapid cooling member 11. The refrigerant supply pipe, the return pipe for vaporized gas, the control unit, and the like are omitted. In the embodiment, the vaporized gas having lost the cooling temperature returns to the compressor 12 housed in the casing 1 in the internal space of the ice layer forming drum 5.
On the other hand, in the upper box-shaped second housing portion 3, the rear housing portion 3a communicates with at least one protruding support portion 3b in the front-rear direction, and a power transmission member 19 is provided in the inner space thereof via front and rear sprockets. That is, reference numeral 15 is an output shaft of the drive motor, reference numeral 16 is an input shaft of the ice layer forming drum, reference numeral 17 is a drive sprocket, reference numeral 18 is a driven sprocket, and reference numeral 19 is a power transmission member such as a chain, a timing belt, or the like. It is preferable that a drive motor 21 described later be disposed in a horizontal state in the rear housing portion 3a, and the ice layer forming drum 5 be disposed in the installation space portion 4 as shown in fig. 3.
Next, the left and right bearing members 7 and the ice layer forming drum 5 will be described together with other members with reference to fig. 5. In order to facilitate the observation of the main part of the present invention, fig. 5 schematically shows a drive motor 21, a power transmission member 19, a water introduction path 23 connected to the water supply unit 6 for storing water W for ice shaving and having an automatic or manual opening/closing valve 22, a tubular flow rate control member (virtual line) 24 detachably connected to the water introduction path, a water storage tray (virtual line) 25 disposed below the ice layer forming drum 5, and the like.
In fig. 5, reference numeral 27 denotes a pair of vertical support plates made of metal fixedly provided on inner wall surfaces of left and right projecting support portions 3b, reference numeral 7 denotes a pair of left and right bearing members fixedly provided on the vertical support plates 27 and having ball bearings 7a on inner circumferential surfaces, reference numeral 5 denotes a hollow cylindrical ice layer forming drum rotatably supported by the bearing members 7, reference numerals 28 and 29 denote elongated cylindrical tubes constituting the inside and outside of the rapid cooling member 11, reference numeral 30 denotes a cylindrical protrusion provided on one side wall (left side wall in the drawing) of the ice layer forming drum 5, and reference numeral 31 denotes a packing fixedly provided on the cylindrical protrusion. Further, one end of the other refrigerant supply pipe 33 and one end of the discharge pipe 34 for returning the gasified gas are connected to the projecting outer ends (left side in the drawing) of the inner and outer elongated cylindrical pipes 28 and 29 via a bidirectional joint 32.
In the embodiment, the ice layer forming drum is made of a metal material having excellent quenching property, so that the cooling heat of the metal material is not transmitted as much as possible (the cooling heat is not dissipated) through the pair of left and right vertical support plates 27 made of metal, and the bearing members 7 are formed into a cylindrical body having a flange portion using a synthetic resin material (preferably teflon).
Next, the structure of the sealing packing 31 of the apparatus X will be described with reference to fig. 6 and 7. In the embodiment, a cylindrical protrusion 30 rotatably supported by one of the left and right bearing members 7 is provided on one side wall of the ice layer forming drum 5, elongated cylindrical pipes 28,29 constituting the inside and outside of the rapid cooling member 11 are concentrically inserted and fitted into the cylindrical protrusion 30, and at least a first sealing material 37 is provided between the outer peripheral surface of the outer elongated cylindrical pipe 29 and the inner peripheral surface of an annular recessed portion 36 formed in the cylindrical protrusion 30.
The sealing packing 31 has various forms. The sealing packing 31 of the embodiment includes: a first sealing member 37 having a horizontally chevron-shaped notch 37a on one side surface (left side in the drawing) of the receiving side having a rectangular cross section; a second sealing member 38 having a notch 38a in a horizontal chevron shape on one side surface of the receiving side, and a protrusion 38b in a chevron shape pressed into the notch 37a on the other side surface (right side in the drawing) opposite to the one side surface; a third sealing member 39 having substantially the same form as the second sealing member 38; a final fourth sealing member 40 having a mountain-shaped protrusion 40b which is pressed so as to bite into the mountain-shaped notch 39a of the third sealing member 39; and a packing presser 42 having a plurality of fixing members 41 screwed into the cylindrical protrusion 30.
In this way, the preferable seal packing 31 is configured such that the thick second seal member 38 is disposed in the axial direction of the outer elongated cylindrical tube 29 in common with the thick first seal member 37, and the third seal member 39 and the like after the thick second seal member 38 are pressed against each other in a close contact state.
Next, the flow control member 24 and the water storage tray 25 will be described with reference to fig. 8 and 9. As described above, the water introduction path 23 is provided with the automatic or manual opening/closing valve 22, the opening/closing valve 23 is connected to the water storage tray 25 with the tubular flow rate control member 24, and the opening 24a at the upper end of the flow rate control member 24 has a large diameter while the control opening 24b at the lower end has a smaller diameter than the opening, so that the water for ice shaving is gradually supplied to the water storage tray.
The water storage tray 25 having an open upper end has a flat portion 25a for receiving the "water W for ice shaving", and a shallow recess 25b continuous with the flat portion, and the inner surface of the bottom wall of the recess is formed in an inwardly curved shape so that the arc-shaped lower side of the ice layer forming drum 5 is always immersed in the water for ice shaving. Next, the water source 60, the ion exchange resin unit 61, and the filtration processing unit 62 will be described with reference to fig. 10 and 11. The water source 60 is preferably tap water, for example. However, it may be lake water or well water. An example of the ion exchange resin section 61 is shown in fig. 11. The filtration processing unit 62 may be single or plural, and a hollow fiber membrane capable of removing bacteria is preferably used. In this way, the "water for ice shaving W" softened by the ion exchange resin portion 61 and removed of the bacteria by the filtration processing portion 62 is temporarily stored in the water supply portion 6 of the casing 1 of the embodiment. The ion exchange resin section 61 as the soft water producing section includes a producing tank 61a having an inflow section and an outflow section at an upper end, a granular ion exchange resin 61b incorporated in the producing tank, and a tubular delivery pipe 61c incorporated in the producing tank.
Next, fig. 12 shows the positional relationship between the ice layer forming drum 5 and the water storage tray 25. Unlike the complicated water supply means of patent document 1, the water storage tray 25 of the embodiment is disposed below the ice layer forming drum 5 in a horizontal state, and when the on-off valve 22 and the drive motor 21 are activated simultaneously or slightly delayed to be in the "open state" by a control signal of the control unit, the water storage tray 25 temporarily receives the "water for ice shaving W" flowing out from the opening 24a at the upper end of the flow rate control member 24. At this time, the amount of the "water for ice shaving W" flowing out from the flow rate control member 24 preferably substantially corresponds to the thickness and amount of the film-like ice layer formed on the outer peripheral surface of the ice layer forming drum 5.
Next, fig. 13 is an explanatory diagram of the cover 45. The cover 45 is transparent or translucent. The cover 45 has left and right end surfaces formed in a substantially L-shape and covers the exposed outer peripheral surface of the ice layer forming drum 5 and the cutting blade 47. When the cover 45 is provided in the mounting space portion 4, the base end portion of the horizontal portion may be pivotally supported on the upper portion of the inner end of the left and right protruding support portions 3b, and the vertical or inclined portion of the cover 45 may be lifted upward from the front side.
Next, fig. 14 is a schematic cross-sectional explanatory view of the inner and outer elongated cylindrical tubes 28,29 constituting the rapid cooling member 11. The outer elongated cylindrical tube 29 injects the refrigerant, which is pressure-fed from the compressor 12 housed in the casing through the heat exchange member 13, into the internal space of the ice layer formation drum 5 in a vaporized state through one or more small injection holes 29a, while the inner elongated cylindrical tube 28 receives the vaporized gas, which has lost the cooling temperature and is injected into the internal space, through one or more suction ports 28 a.
Next, fig. 15 is a schematic explanatory view of the rapid cooling member 11 that is cyclically connected to the ice layer forming drum 5. In fig. 15, reference numeral 12 denotes a compressor which is incorporated in the first housing portion 2 of the casing and compresses a refrigerant. The compressor 12 includes, for example, a tank main body, a condenser for condensing a compressed refrigerant, a condenser fan for discharging heat generated in the condenser during condensation to the outside of the system, an expansion valve, and the like.
The type of the refrigerant is not particularly limited, and may be appropriately selected from, for example, a hydrocarbon-based refrigerant, a carbon dioxide refrigerant, and the like, which are generally used. In the embodiment, since the seal packing 31 is used for one bearing 7, the large (powerful) compressor 12 can be used.
Finally, the cutting blade 47 and the guide plate 48 will be briefly described. The cutting blade 47 is supported by the left and right projecting support portions 3b of the housing 1 in a horizontal state so as to be substantially in contact with the front side of the ice layer forming drum 5, and cuts the film-like ice layer 50 formed rapidly on the outer peripheral surface of the ice layer forming drum 5 during the rotation. Here, "to be substantially in contact" also includes a meaning in the case where the two are physically separated subtly. In the embodiment, the cutting blade 47 is orthogonal to the outer peripheral surface so as to be located below the center axis of the ice layer forming drum 5. The angle of the tip portion of the cutting blade 47 is preferably set to be slightly upward or/and slightly downward, etc. in accordance with the rotation direction of the ice layer forming drum 5.
In the embodiment, the cutting blade 47 is located below the center line of the ice layer forming drum 5 in the axial direction and on the front side of the outer peripheral surface of the ice layer forming drum 5. When the "snow-like shaved ice 50 a" is shaved, the ice layer forming drum 5 rotates in the direction of the arrow as shown in fig. 3, but when the film-like ice layer 50 is completely shaved, it rotates in the direction opposite to the direction of the arrow. Therefore, the control unit can control not only the number of rotations but also the rotation direction based on the signal from the input unit.
As shown in fig. 13, the guide plate 48 is preferably provided integrally with the surface of the cutting edge 47. The guide plate 48 has a horizontally long rectangular opening 49 through which the shallow-bottomed water tray 25 can be placed.
Therefore, the guide plate 48 can freely pick and place the water tray 25 with a shallow bottom, and can guide the snow-like shaved ice 50a cut by the cutting blade 47 to the opening in the predetermined direction (the receiving container 10), for example, at the time of cleaning.

2. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
a second sealing material is disposed in the axial direction of the elongated cylindrical tube together with the first sealing material, and one side surface of the second sealing material is in pressure contact with the other side surface of the first sealing material in a close contact state.
3. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 2,
at least the first sealing member and the second sealing member are constituent members of a sealing packing, and opposite side walls thereof are pressed against each other by a packing presser having a plurality of fixing members screwed into the cylindrical protrusion.
4. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the water introduction path is provided with an automatic or manual opening/closing valve, and a flow rate control member is connected to the opening/closing valve toward the water storage tray, and the opening of the upper end portion of the flow rate control member is formed to have a large diameter, and the control opening of the lower end portion is formed to have a smaller diameter than the opening, so that the water for ice shaving can gradually flow toward the water storage tray.
5. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the water supply part of the housing temporarily stores the 'water for ice shaving' softened by the ion exchange resin part and removed of the bacteria by the filtering treatment part, and the water supply part is further connected with a water introduction path having an opening and closing valve.
6. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the water storage tray with an open upper end has a flat portion for receiving "water for ice shaving" and a shallow recess continuous with the flat portion.
7. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the left and right bearing members are formed into a cylindrical body having flange portions using a synthetic resin material.
8. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
a cover for covering the exposed outer peripheral surface of the ice layer forming drum and the cutting blade is provided in the space portion for mounting the protruding support portion.
9. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the outer elongated cylindrical tube injects a refrigerant, which is pressure-fed from a compressor housed in a casing, into an internal space of the ice layer forming drum in a vaporized state through a small injection hole, while the inner elongated cylindrical tube receives a vaporized gas, which has lost a cooling temperature and is injected into the internal space, through a suction port, and returns the gas to the compressor housed in the casing.
10. The rapid cooling ice shaving manufacturing apparatus as claimed in claim 1,
the guide plate has an opening for freely taking and placing the water storage tray with a shallow bottom.
