Description

  The present invention relates to an ice storage detection device for an ice making machine that detects the presence or absence of ice blocks stored in an ice storage chamber.

  An automatic ice maker (ice maker) that continuously manufactures ice blocks of a required shape is suitably used in facilities such as coffee shops and restaurants and other kitchens. The ice making mechanism of these ice making machines has various types, such as a spray type that continuously supplies ice making water by supplying ice making water from below to a large number of ice making chambers that open downward, and a flow down type that causes ice making water to flow down on the ice making surface. There are various types. The ice making machine is configured such that the ice making mechanism is disposed above an ice storage in which an ice storage chamber is defined, and ice blocks produced by the ice making mechanism are discharged and stored in the ice storage chamber.

  In the ice making machine, an ice storage detection device (for example, refer to Patent Document 1) capable of detecting the presence or absence of ice blocks is disposed inside the ice storage, and operation control of the ice making mechanism is performed according to the detection state of the ice storage detection device.

JP-A-9-303925

  In the ice storage detection device disclosed in Patent Document 1, since the proximity switch is disposed on the inner side surface of the holding plate, water droplets (hereinafter referred to as condensed water) condensed on the inner side surface of the holding plate follow the inner side surface. When the water flows down, the condensed water may wet the proximity switch and cause a detection failure.

  In the ice storage detection device, a gap is provided between the lower end of the movable portion disposed on the holding plate and the lower surface of the holding plate to allow the movable portion to swing. In this case, the condensed water adhering to the lower end of the movable part, the lower end of the holding plate, etc., or the melted water of the ice block (hereinafter sometimes collectively referred to as condensed water) takes out the ice block from the ice storage chamber. The air pressure generated when closing the open / close door opens to the inside of the holding plate through a gap, and this condensed water adheres to the surface facing the magnet of the proximity switch facing the movable part side. Sometimes. If condensed water or the like adheres to the facing surface of the proximity switch, the magnet is held in the proximity state by the surface tension of the condensed water or the like when the magnet is close to the proximity switch, and hinders the smooth swinging of the movable part. There was a fear.

  In view of the above-described problems inherent in the prior art, the present invention has been proposed to suitably solve these problems, and it is possible to reliably detect the presence or absence of ice blocks stored in an ice storage chamber. An object is to provide an apparatus.

In order to overcome the above-mentioned problems and achieve the intended purpose, an ice storage detection device for an ice making machine according to claim 1 of the present application is provided:
An ice storage chamber for storing ice blocks released from the ice making mechanism is arranged inside an ice storage, and a switch case having an opening communicating with the ice storage chamber and a storage in the ice storage chamber facing the opening.

And a proximity switch that is disposed inside the switch case so that the magnet disposed on the movable member can be detected, and detects the presence or absence of an ice block by moving the magnet toward and away from the movable member when the movable member swings. In the ice storage detection device of
On the bottom plate at the inner surface of the left and right side plates of the switch case and spaced from the inner surface of the rear plate, a convex portion protruding upward from the bottom plate is provided,
The proximity switch is attached to the attachment portion provided on the upper surface of the convex portion , and the detection surface is attached to the rear side opposite to the front opening of the switch case,

The detection surface of the magnet faces the detection surface of the proximity switch through a rear wall portion of the attachment portion in a state where the detection body does not detect ice .

  According to the first aspect of the present invention, the proximity switch is disposed on the upper surface of the convex portion protruding from the inner side surface of the inner bottom surface of the switch case, so that the dew condensation that adheres to the inner side surface and flows down. Water or the like does not wet the proximity switch, can prevent detection failure, and can reliably detect the presence of ice blocks. Further, even if condensed water or the like accumulates on the inner bottom surface of the switch case, the proximity switch is not easily submerged because the proximity switch is spaced apart from the bottom by a predetermined height.

In the invention according to claim 2, the magnet is disposed on the movable member so as to face the opposite side of the opening in the switch case across the proximity switch, and the ice block stored in the ice storage chamber is detected. The gist is that the magnet is configured to detect the presence of an ice block by moving away from the proximity switch when the movable member is tilted by contacting the body.
According to the invention of claim 2, since the magnet is configured to approach and separate from the proximity switch on the side opposite to the opening of the switch case, the gap between the bottom surface of the switch case and the lower end of the movable body Even when condensed water or the like is scattered in the switch case from the gap, it is possible to prevent the condensed water or the like from adhering to the facing surface of the proximity switch and the magnet. Therefore, when the magnet comes close to the proximity switch, surface tension such as condensed water does not act on the magnet, and smooth swinging of the movable member can be achieved.

In the invention which concerns on Claim 3, the protrusion which protrudes toward the other opposing surface and restricts the opposing surfaces in surface contact with at least one of the opposing surfaces of the proximity switch and the magnet that are close to and away from each other. The gist is to be provided.
According to the third aspect of the present invention, since the protrusion for restricting the surface contact between the proximity switch and the magnet is provided, even if condensed water or the like adheres to the surface, The surface tension of water or the like can be prevented from acting so as to attract the proximity switch and the magnet, and smooth swinging of the movable member can be achieved.

  According to the ice storage detection device for an ice making machine according to the present invention, the proximity switch can be prevented from getting wet by condensed water or the like, and the presence or absence of ice blocks can be reliably detected.

Further, the horizontal dimension of the front opening 18a is set to be substantially the same as the horizontal dimension of the ice discharge part 32 in the ice making mechanism 14, as shown in FIG. Shaft holes 28a, 28a are formed at upper positions on the front side of the left and right side plates 28, 28, and a shaft portion 42 (described later) of the movable member 24 is rotatably inserted into the shaft holes 28a, 28a. It is like that.

  On the inner surfaces of the left and right side plates 28, 28, as shown in FIG. 4, stoppers 34 extending in a predetermined length toward the other side plate 28 rearward from the drilled position of the shaft hole 28a are respectively provided in the vertical direction. It is provided over the full length of. On the upper surface of the bottom plate 26, a weir member 36 extending between the side plates 28, 28 at a position rearward of the position where the stopper 34 is formed is projected upward at a predetermined height. Further, on the upper surface (inner bottom surface) of the bottom plate 26, it is located behind the position where the dam member 36 is formed and at a position separated from the inner surfaces (inner side surfaces) of the left and right side plates 28, 28 and the rear plate 30. A convex portion 38 that protrudes to a position higher than the weir member 36 is provided. A mounting portion 40 of the proximity switch 20 is provided on the upper surface of the convex portion 38, and the proximity switch 20 has the detection surface directed rearward (opposite to the front opening 18a). It can be detachably attached in a posture. The attachment portion 40 is formed in a frame shape that opens upward so that the proximity switch 20 can be accommodated, and the rear surface of the rear wall 40a on the rear side facing the detection surface of the proximity switch 20 accommodated in the attachment portion 40 is the magnet. 22 is an opposite surface to the front surface (both described later) of the front wall portion 48a of the mounting portion 48 to which 22 is mounted. The height dimension of the weir member 36 is set to be larger than the height dimension of the gap formed between the lower end of the movable body 44 (described later) of the movable member 24 disposed in the switch case 18 and the bottom plate 26, Condensed water or the like that enters the switch case 18 from the gap is configured to prevent it from entering behind the weir member 36.

  As shown in FIG. 5, the movable member 24 includes a shaft portion 42 in which shaft ends are rotatably inserted into shaft holes 28 a, 28 a of the left and right side plates 28, 28 in the switch case 18, and the shaft portion 42. A plate-like movable body (detecting body) 44 that extends obliquely downward toward the front side by a predetermined length, and extends at a predetermined length obliquely downward from the center in the left-right direction of the shaft portion 42 toward the rear side. The holding unit 46 and the magnet 22 disposed at the extending end of the holding unit 46 are basically configured. As shown in FIGS. 1 and 2, the movable body 44 is set to a size that can swing in the front opening 18 a of the switch case 18 in the front-rear direction (inside-outward direction), and ice blocks stored in the ice storage chamber 12 are stored in the movable body 44. When pressed against the front surface of the movable body 44, the movable member 24 swings so that the movable body 44 tilts rearward (inside the switch case 18).

  A mounting portion 48 extending downward is provided at the extending end of the holding portion 46, and the magnet 22 is mounted on the mounting portion 48. As shown in FIG. 3, the mounting portion 48 is formed in a concave shape that opens rearward to accommodate the magnet 22, and the front wall portion 48 a on the front side facing the front surface (detected surface) of the magnet 22 accommodated in the mounting portion 48. However, the front wall portion 48a is positioned so as to face the rear wall portion 40a of the mounting portion 40, and the front wall portion 48a moves toward and away from the rear wall portion 40a of the mounting portion 40 as the movable member 24 swings. It is configured as follows.

  In the state where the movable member 24 is swingably disposed between the left and right side plates 28, 28 via the shaft portion 42, the front surface (opposing surface) of the front wall portion 48a of the mounting portion 48 is shown in FIG. As shown in FIG. 4, the center of gravity position is set so as to swing in the direction close to the rear surface (opposing surface) of the rear wall portion 40a of the mounting portion 40. When the front surface of the front wall portion 48a of the mounting portion 48 is close to the rear surface of the rear wall portion 40a of the mounting portion 40, the lower portion of the movable body 44 extends forward from the front opening 18a by a predetermined length. It is configured as follows. That is, when an ice block comes into contact with the movable body 44 extending forward from the front opening 18a from the front side and the movable body 44 is pushed rearward and tilted, the front wall portion 48a of the mounting portion 48 is The movable member 24 swings so as to be separated from the rear wall portion 40a of the mounting portion 40 rearward. In the embodiment, the proximity switch 20 detects the ice block “absent” in a state where the front wall portion 48a of the mounting portion 48 is close to the rear wall portion 40a of the attachment portion 40, and from the rear wall portion 40a of the attachment portion 40. It is configured to detect an ice block “present” in a state where the front wall portion 48a of the mounting portion 48 is separated. Therefore, in the embodiment, regarding the state of the movable member 24, the state in which the magnet 22 is in proximity to the proximity switch 20 and the ice block “nothing” is detected is referred to as “iceless state”. A state where the ice block “presence” is detected at a distance is referred to as “ice state”.

  A protrusion 50 protruding forward is provided on the front surface of the front wall 48a of the mounting portion 48. As shown in FIG. 3, when the movable member 24 is in an ice-free state, the protrusion 50 is attached to the mounting portion. 40 is configured to abut against the rear surface of the rear wall portion 40a so that the front surface of the front wall portion 48a does not come into surface contact with the rear surface of the rear wall portion 40a. The projecting dimension of the projecting portion 50 is such that the magnet 22 can be detected by the proximity switch 20 in a state where the projecting portion 50 is in contact with the rear surface of the rear wall portion 40a of the mounting portion 40, and the rear wall portion 40a Even if condensed water or the like adheres to the front surface or the rear surface of the front wall portion 48a, the front wall portion 40a and the front wall portion 40a and the front wall are separated by a distance at which the surface tension of the condensed water or the like does not act between the opposing surfaces of both wall portions 40a and 48a It is set so as to define a gap with the wall portion 48a.

(Effects of Example)
Next, the operation of the ice storage detection device for an ice making machine according to the above-described embodiment will be described.

  In the ice making machine, ice blocks are continuously generated by the ice making mechanism 14 and the ice blocks are accumulated in the ice storage chamber 12 to a position where the ice storage detection device 16 is disposed, whereby the accumulated ice blocks are moved to the movable member. The 24 movable bodies 44 are contacted from the front side, and the movable bodies 44 are pushed rearward. At this time, the movable member 24 swings in a direction in which the front wall portion 48 a of the mounting portion 48 is separated from the rear wall portion 40 a of the attachment portion 40 in the rearward direction, and the magnet 22 is separated from the proximity switch 20. As a result, the proximity switch 20 detects the presence of ice blocks, and the ice making machine determines that a predetermined amount of ice blocks have been stored in the ice storage chamber 12 by the control means, and the ice making operation of the ice making mechanism 14 is stopped. Note that the movable body 44 pushed into the switch case 18 by the ice block is regulated to contact with the stoppers 34, 34, and is held in a state where there is ice without further tilting.

  When the ice block is taken out from the ice storage chamber 12 to reduce the storage amount and the pressing state of the movable body 44 by the ice block is released, the movable member 24 in the presence of the ice has the front wall of the mounting portion 48 by its own weight. The part 48a swings in the direction close to the rear wall part 40a of the attachment part 40 and returns to the ice-free state, and the magnet 22 approaches the proximity switch 20. At this time, the proximity switch 20 detects the absence of ice blocks, and the ice making machine determines that a predetermined amount of ice blocks are not stored in the ice storage chamber 12 by the control means, the operation of the ice making mechanism 14 is restarted, and ice blocks are removed. Generated. Then, ice blocks accumulate again to the position where the ice storage detection device 16 is disposed, and when the ice storage detection device 16 detects the presence of ice blocks as described above, the operation of the ice making mechanism 14 is stopped. As described above, the ice making machine can control the operation of the ice making mechanism 14 according to the detection state of the ice block by the ice storage detection device 16 and can always maintain a state where a predetermined amount of ice block is stored in the ice storage chamber 12.

  In the embodiment, the movable member 24 is configured to return from its ice-free state to its ice-free state by setting the position of the center of gravity, so that the movable member 24 can be held in the ice-free state or the ice-free state. An elastic member such as a spring can be omitted, the number of parts can be reduced, and the configuration can be simplified, thereby reducing the probability of occurrence of a failure. Further, the convex portion 38, the dam member 36 and the stoppers 34, 34 provided on the switch case 18 also serve to reinforce the switch case 18.

  In the ice making machine, when the open / close door is opened and closed, outside air enters the ice storage chamber 12 to avoid condensation on the inner side wall surface of the ice storage 10 or the inner side surface of the switch case 18 in the ice storage detection device 16. I can't. In this case, the proximity switch 20 disposed in the switch case 18 is positioned away from the inner surfaces of the left and right side plates 28 and 28 and the inner surface of the rear plate 30 as shown in FIG. , The dew condensation water flowing down the inner surfaces of the side plates 28 and 28 and the rear plate 30 is prevented from wetting the proximity switch 20 because it is disposed on the upper surface of the convex portion 38 protruding from the upper surface of the bottom plate 26. The That is, it is possible to prevent water from entering the proximity switch 20 and causing a failure or a detection failure, and a state where the presence or absence of an ice block is reliably detected can be maintained.

  Here, the condensed water adhering to the lower end of the movable body 44 and the front portion of the bottom plate 26 in the switch case 18 due to the wind pressure generated when closing the open / close door that is opened to take out the ice block from the ice storage chamber 12. May scatter from the gap between the lower end of the movable body 44 and the bottom plate 26 into the switch case 18. However, in the embodiment, the bottom plate 26 is provided with the weir member 36 that protrudes from the upper surface to a position higher than the gap, so that condensed water or the like entering from the gap is scattered to the location where the proximity switch 20 is disposed. Is prevented by the weir member 36. Moreover, as shown in FIG. 2, the rear wall portion 40a of the mounting portion 40 where the front wall portion 48a of the mounting portion 48 of the magnet 22 approaches and separates faces the opposite side of the front opening 18a. Even if dew condensation water or the like scatters beyond the weir member 36, the dew condensation water or the like hardly adheres to the rear surface of the rear wall portion 40a. That is, when the front wall portion 48a of the mounting portion 48 in the movable member 24 is in an ice-free state in the vicinity of the rear wall portion 40a of the mounting portion 40, the front wall portion 48a and the rear wall portion 40a are caused by surface tension such as condensed water. Without being attracted, the movable member 24 can be smoothly swung, and the presence of an ice block can be detected appropriately.

  Furthermore, in the ice-free state of the movable member 24, as shown in FIG. 3, the protrusion 50 protruding from the front wall 48a of the mounting portion 48 abuts on the rear wall 40a of the mounting portion 40. The front surface of the front wall portion 48a and the rear surface of the rear wall portion 40a are not in surface contact. Accordingly, even if condensed water or the like adheres to the front surface of the front wall portion 48a or the rear surface of the rear wall portion 40a, the surface tension of the condensed water or the like acts so as to attract the both wall portions 40a and 48a. Thus, smooth swinging of the movable member 24 can be achieved.

  As described above, since the weir member 36 is formed over the entire length in the left-right direction in the switch case 18 of the embodiment in front of the site where the proximity switch 20 is disposed, the left and right side plates 28, 28 and the rear plate 30. Condensed water that has flowed down each inner surface may accumulate at the bottom. However, since the upper surface of the convex portion 38 on which the proximity switch 20 is disposed faces a higher position than the weir member 36, even if condensed water accumulates at the bottom of the switch case 18 up to the upper end of the weir member 36. The proximity switch 20 will not be submerged.

  Here, the ice blocks discharged from the ice making mechanism 14 accumulate in a mountain shape in the ice storage chamber 12 with the top just below the ice discharge portion 32. As shown in FIG. 2, the ice storage detection device 16 of the embodiment is disposed at a position close to the ice discharge portion 32 of the ice making mechanism 14, so that the ice storage detection device 16 detects the presence or absence of ice blocks at the top of the mountain shape. It can be detected, and an appropriate ice block can be stored in the ice storage chamber 12. Further, since the movable body 44 of the ice storage detection device 16 is configured to extend in substantially the same length in the left-right direction of the ice discharge portion 32, it accumulates when the ice lump removal position from the ice storage chamber 12 is biased. Even if the top position of the mountain shape is changed in the left-right direction, the ice storage detector 16 can detect the presence or absence of ice blocks.

[Example of change]
The present application is not limited to the configuration of the above-described embodiment, and other configurations can be appropriately employed.
1. In the embodiment, the proximity switch is described in the case where the detection surface is disposed so as to face the rear side opposite to the front opening, but the detection surface may be disposed so as to face the front opening. In this case, the movable member is disposed in the switch case so that the magnet mounted on the mounting portion faces the front of the proximity switch disposed on the mounting portion, and the magnet is always separated forward from the proximity switch. In this way, the movable member is biased by an elastic member such as a spring. In this configuration, when the movable body is pushed by the ice block and tilted, the proximity switch detects the presence of the ice block by the proximity of the proximity switch, and the ice block does not come into contact with the movable body. It is only necessary to detect the “absence” of the ice block by separating.
2. In the embodiment, the detection surface of the proximity switch and the detection surface of the magnet are configured to face each other via the rear wall portion of the mounting portion and the front wall portion of the mounting portion.

However, the protrusion may be provided on the rear wall portion of the attachment portion, or a configuration in which the protrusions are provided on both wall portions, respectively. Can do. Also, the shape and number of the protrusions can be set to any shape and number as long as a gap in which surface tension such as condensed water does not act between the opposing surfaces of both wall portions can be formed.
4). A configuration in which a protrusion for separating the proximity switch and the facing surface of the magnet is provided is most suitable. However, if the detection surface of the proximity switch is directed to the side opposite to the opening, condensed water entering from the opening is detected. It is possible to prevent the protrusions from adhering to the surface.
5. In the embodiment, the case where the switch case is arranged on the rear wall so that the movable plate of the ice storage detection device faces the front of the ice storage has been described, but on the left and right side walls that define the ice storage chamber in the ice storage. The switch case may be disposed with the movable plate facing left or right.
6). The arrangement site of the ice storage detection device is not limited to the rear wall or side wall of the ice storage, and may be a member that supports the ice making mechanism.
