Description

  The present invention relates to an ice making machine, and more particularly, to an ice making machine having a drain pan below an ice making mechanism disposed in an ice storage chamber of an ice making machine body.

  For example, FIG. 9 shows a schematic configuration of an injection-type ice making machine that automatically produces ice cubes (ice blocks) by supplying ice-making water from below to a large number of ice-making chambers that are provided in the ice-making chamber and open downward. It is a partially broken perspective view shown. This type of ice making machine 10 divides the inside of an ice making machine main body 11 having a substantially box shape vertically, and an upper space is an ice storage chamber 12 and a lower space is a machine chamber 13.

  An attachment member 18 is disposed at the upper part of the ice making machine main body 11, and the ice making water tank 17 disposed at the lower part of the ice making chamber 15, the water dish 16, and the water dish 16 in which many ice making chambers are formed. An ice making mechanism 14 composed of a water dish tilting mechanism 28 for tilting the water dish 16 together with the ice making water tank 17 is suspended and faces the inside of the ice storage chamber 12. The ice making mechanism 14 sprays ice-making water supplied from the water suction pipe 19 into the ice-making water tank 17 to each ice making chamber of the ice making chamber 15 from the spray hole of the water tray 16 by the water pump 20. It is configured to make ice blocks. When ice cubes are generated in the ice making chamber 15, the water tray tilting mechanism 28 is driven to release the water tray 16 from the ice making chamber 15 in an inclined state, and the generated ice cubes are dropped into the ice storage chamber 12. At the same time, the ice making water tank 17 is tilted together with the water tray 16 to discharge ice making water. Therefore, a drain pan 21 that receives the ice making water discharged from the ice making water tank 17 and discharges it outside the apparatus is disposed below the ice making mechanism 14.

On the other hand, as shown in FIG. 9, the ice making machine body 11 is a box that opens to the top and front of the ice storage chamber 12 in order to facilitate the installation of the ice making mechanism 14 and the like when the ice making machine 10 is assembled. Is formed. Accordingly, a rectangular upper panel 23 capable of completely covering the top surface opening 22 is detachably attached to the top surface opening 22 of the ice making machine body 11. The front opening 24 of the ice making machine body 11 is provided with an opening / closing door 25 that can be opened to the front of the ice making machine 10, and a front side portion (from the drain pan 21) of the ice making mechanism 14 in the front opening 24. A horizontally elongated front panel 26 is attached to the upper portion. The front panel 26 is not exposed to the outside when the opening / closing door 25 is closed to the ice making machine main body 11, and when the opening / closing door 25 is opened from the ice making machine main body 11, the ice making mechanism 14 is externally connected. And prevents the hand from entering the vicinity of the ice making mechanism 14. An ice making machine having such a configuration is disclosed in Patent Document 1, for example.

  By the way, in the conventional jet type ice making machine 10 shown in FIG. 9, a gap is formed between the drain pan 21 and the front panel 26, and the lateral width L1 of the front panel 26 is the front opening 24. Whereas the width dimension L is set larger than the width dimension W, the width dimension L2 of the drain pan 21 is about half of the width dimension W of the front opening 24. Therefore, when condensation occurs on the back surface of the front panel 26 facing the ice making mechanism 14, the condensed water drops without being collected on the drain pan 21, resulting in inconvenience of freezing on the bottom surface of the ice storage chamber 12. There was a risk of entering the gap of the ice making machine body 11 to induce rusting. In particular, since the front panel 26 is a plate member formed by bending a thin stainless steel plate or the like, the heat insulation is low, and condensation easily occurs due to a temperature difference between the surface side exposed to the outside and the back side facing the ice making mechanism 14. It was.

  In general, in an ice making machine, it is necessary to periodically clean the inside of the ice making water tank 17, the water tray 16, and the ice making chamber 15 of the ice making mechanism 14. It is necessary to feed a predetermined chemical (such as a cleaning agent) from the chemical inlet 27. However, in the conventional ice making machine 10 shown in FIG. 9, since the opening is not formed in the front panel 26, the chemical is put into the ice making water tank 17 with the front panel 26 removed from the ice making machine body 11. Therefore, when the ice making mechanism 14 is cleaned, the front panel 26 is attached and detached, and the cleaning operation is complicated.

  Therefore, in view of the problems inherent in the above-described conventional technology, the present invention has been proposed to suitably solve this problem, and the condensed water generated in the ice storage chamber is appropriately recovered into the drain pan, It is an object of the present invention to provide an ice making machine capable of preventing condensed water from freezing in an ice storage chamber and inducing rust generation in the ice making machine body.

That is, the opening 72 is used for charging chemicals when charging chemicals (cleaning agents) used for cleaning the ice making mechanism 34 into the chemical charging port 27 of the ice making water tank 17. Accordingly, when the ice making mechanism 34 is cleaned, the chemical can be charged into the ice making water tank 17 without removing the drain pan 60 and the front inner panel 65.

  Further, as shown in FIGS. 1 to 4, a frame-shaped holding portion 73 is provided at the lower portion of the front inner panel 65 so as to face the front opening 55. The holding portion 73 is for hooking and holding a bucket 74 that is used for taking out ice blocks stored in the ice storage chamber 32. When forming the drain pan 60 and the front inner panel 65, the front inner It is formed integrally with the panel 65.

  Furthermore, in the ice making machine 30 of the embodiment, as shown in FIG. 4, the front panel 75 made of stainless steel covers the front wall portion 66 of the front inner panel 65 in the front opening 55 of the ice making machine body 31. Installed. The front panel 75 is used to improve the appearance of the ice making machine 30, to attract the open / close door 56 closed to the ice making machine body 31 and to hold the front inner panel 65. Fitting pieces 75A, 75A that are fitted in fitting grooves 66A, 66A provided on the front surface of the front wall 66 so as to extend laterally. 75B is provided at the upper and lower edges. When the front panel 75 is attached to the ice making machine body 31, as shown in FIG. 5, each fitting piece 75B is fitted into the corresponding fitting groove 66A, and the front end of the rib 70 is fitted with the front panel 75.

  As shown in FIGS. 4 and 5, the front panel 75 is formed with a panel opening 78 that aligns with the opening 72 of the front inner panel 65, and the opening 72 is closed to be openable. A sliding shutter member 79 is disposed. The shutter member 79 is always held in a state in which the panel opening 78 is closed. When the ice making mechanism 34 is cleaned, the shutter member 79 is slid laterally to open the panel opening 78. A chemical is allowed to enter the chemical inlet 27 of the ice making water tank 17 via 72.

(Operation of Example)
Next, the operation of the ice making machine of the embodiment configured as described above will be described. In the state in which the ice making mechanism 34 is in the ice making operation, as shown in FIG. 2, the water tray 16 is closed with respect to the ice making chamber 15 and is in a horizontal state. Reserved.

  When the formation of ice cubes (ice blocks) is completed by the ice making water sprayed and supplied into the ice making chamber 15, as shown in FIGS. 1 and 7, the water pan tilting mechanism 28 is driven to move the water tray 16 to the ice making chamber 15. When the ice is released, the ice cubes are dropped and released to the bottom of the ice storage chamber 32. Further, since the ice making water tank 17 is displaced to the drainage position with the tilting of the water tray 16, the ice making water stored in the ice making water tank 17 is transferred from the tank drain provided at the bottom of the tank to the drain pan 60. It is discharged towards. When the discharge of ice cubes and the discharge of ice making water are completed, the water tray tilting mechanism 28 is driven to close the water tray 16 with respect to the ice making chamber 15, and the ice making water tank 17 is moved to the water storage position. The next ice making operation is resumed.

  Since the front panel 75 is attached to the front opening 55 of the ice making machine body 31, a space 77 is defined between the front panel 75 and the front inner panel 65, and the air present in the space 77 is formed. Functions as a heat insulating layer. Therefore, the ice making machine 30 according to the embodiment has a large temperature difference between the back side of the front inner panel 65 (inside the ice storage chamber 32 in which the ice making mechanism 34 is disposed) and the front side (outside) of the front inner panel 65. The back surface of the front inner panel 65 is difficult to condense.

  Since the front inner panel 65 is a molded member having a required thickness made of synthetic resin, the front inner panel 65 itself also functions as a heat insulating member. That is, since the front inner panel 65 that functions as a heat insulating member is disposed on the front side of the ice making machine main body 31, the heat insulating performance on the front side of the ice making machine main body 31 is suitably improved. Therefore, due to the heat insulating effect of the front inner panel 65 disposed between the ice making mechanism 34 and the front panel 75, condensation on the front surface of the front panel 75 can be suitably suppressed.

  However, when the opening / closing door 56 is frequently opened and closed in the course of the ice making process by the ice making mechanism 34, the back surface of the front inner panel 65 facing the ice making mechanism 34, that is, the back surface of the front wall portion 66 or the inclined wall. Condensation may occur on the back surface of the portion 67. When condensation occurs on the back surface of the front inner panel 65, as shown in FIG. 3 (b), the dew condensation water generated on the back surface on the left side of the front (the left side in FIG. 3 (a)) where the drain pan 60 directly faces. After flowing down along the back surface of the inclined wall portion 67 from the back surface of the front wall portion 66, it is directly collected into the drain pan 60. On the other hand, as shown in FIG. 3 (b), the dew condensation water generated on the rear right side (the right side in FIG. 3 (a)) where the drain pan 60 does not directly face flows down once to the guide rod 71. It moves to the drain pan 60 side along the guide rod 71 and is collected in the drain pan 60. That is, in the ice making machine 30 of the embodiment, all the condensed water generated on the back side of the front inner panel 65 is collected by the drain pan 60 and discharged outside the apparatus, and does not drop onto the bottom of the ice storage chamber 32. Furthermore, the condensed water generated on the surface of the water pump 20 or the water supply valve is dripped on the back side of the inclined wall portion 67, and flows down along the back surface of the inclined wall portion 67 and is then collected in the drain pan 60. The

  Further, when the ice making mechanism 34 is cleaned, the shutter member 79 of the front panel 75 is slid to open the panel opening 78 so that the panel opening 78 and the opening 72 formed in the front inner panel 65 are passed through. Thus, a predetermined chemical can be easily charged into the chemical inlet 27 of the ice making water tank 17. That is, it is not necessary to remove the front panel 75, the drain pan 60, and the front inner panel 65 from the ice making machine main body 31 during the cleaning operation of the ice making mechanism 34. When maintenance of the ice making mechanism 34 is performed, the maintenance work can be performed by removing the front panel 75, the drain pan 60, and the front inner panel 65 from the ice making machine main body 31. However, the front panel 75 can be removed from the ice maker main body 31 simply by removing the two screws 76, and the front inner panel 65 and the drain pan 60 can be removed integrally from the ice maker main body 31 by removing several screws. be able to.

  Further, in the ice making machine 30 of the embodiment, the left side frame member 40 and the right side frame member 41 made of synthetic resin constituting the machine room 33 are disposed on both lower sides of the ice making machine body 31. The overall weight is reduced and the strength is improved. Even if water generated by melting ice cubes or ice making water flows from the gap between the members constituting the ice making machine body 31 and reaches the machine chamber 33, the left side frame member 40 and the right side made of synthetic resin Since the side frame member 41 does not rust, the rigidity of the ice making machine main body 31 can be maintained over a long period of time.

  Therefore, according to the ice making machine of the embodiment, the front inner panel 65 that extends upward and faces the front side of the ice making mechanism 34 and aligns with the front opening 55 of the ice storage chamber 32 is integrally formed on the front side of the drain pan 60. Therefore, the condensed water generated on the back side of the front inner panel 65 is completely guided to the drain pan 60 and then discharged outside the apparatus. The condensed water drops into the ice storage chamber 32 and freezes, Entering into the gap between the ice making machine main bodies 31 can be suitably prevented. Moreover, since the width L3 of the front inner panel 65 is set to be the same as the width W of the front opening 55 of the ice making machine body 31, the ice making mechanism 34 can be covered appropriately. Further, since the drain pan 60 and the front inner panel 65 are integrally formed members, when installed in the ice storage chamber 32 of the ice making machine main body 31, a function as a reinforcing member can be expected. Since the front inner panel 65 is formed integrally with the drain pan 60, there is no increase in the number of parts due to the provision of the front inner panel 65, and the number of assembling steps for the ice making machine body 31 does not increase. The manufacturing cost of 30 does not increase.

  Further, by providing the front inner panel 65 with an opening 72 facing the chemical inlet 27 of the ice making water tank 17, the opening 72 can be formed without removing the drain pan 60 and the front inner panel 65 from the ice making machine body 31. Accordingly, chemicals can be introduced into the ice making water tank 17 and the ice making mechanism 34 can be cleaned easily and efficiently.

Further, by attaching the front panel 75 to the front side of the ice making machine body 31, a space 77 is defined between the front panel 75 and the front inner panel 65, so that dew condensation occurs on the back surface of the front inner panel 65. It becomes difficult and the generation of condensed water can be suppressed. Further, since the panel opening 78 is provided in the front panel 75, it is not necessary to remove the front panel 75 from the ice making machine body 31 when the ice making mechanism 34 is cleaned, and the ice making mechanism 34 is easily and efficiently cleaned. Can be done.

  Furthermore, the left side frame member 40 and the right side frame member 41 that define the machine room 33 are made of a lightweight and rigid synthetic resin at the lower part of the ice making machine body 31, thereby reducing the weight of the ice making machine 30. In addition, since no rust is induced even when condensed water or ice making water enters, rigidity can be maintained over a long period of time.

  FIG. 8 shows another example of the bucket holding portion 73 formed integrally with the front inner panel 65. As shown in FIG. 8A, the bucket holding portion 73 according to this another example is formed in a recessed portion formed on the right side of the front surface of the inclined wall portion 67 of the front inner panel 65 so as to be spaced apart by a required distance in the left-right direction. As shown in FIG. 8 (b), the bucket 74 can be inserted and removed from the front side and can be latched and held in a suspended state. Each holding plate 80, 80 is formed with stepped portions 80A, 80A at substantially the center in the vertical direction, and the lower side of the stepped portions 80A, 80A is set narrowly between both holding plates 80, 80, The upper side of the step portions 80A and 80A is set wide. That is, the bucket 74 is suspended from the bucket holding portion 73 in a suspended state by pushing the tip widening portion formed at the tip of the handle 74A in the bucket 74 into alignment with the widening portions on the upper side of the holding plates 80 and 80. It can be stopped. In the case of the bucket holding portion 73 having a form as another example, when the bucket 74 is removed, there is no protruding portion of the front inner panel 65 downward, so the front opening of the ice storage chamber 32 when the open / close door 56 is opened. The area is increased, and the effect of facilitating the ice removal work can be expected. In addition, a bucket holding portion 73 is formed in the recessed portion on the front side of the front inner panel 65, and the bucket 74 can be held in a posture that does not extend to the back side of the ice storage chamber 32, so that the amount of ice stored in the ice storage chamber 32 is increased. Can be expected.

In the above embodiment, the front panel 75 is provided in the front opening 55 of the ice making machine body 31, but there is no problem even if the front inner panel 65 is exposed to the outside, or the closed door 56 is closed. The front panel 75 can also be omitted if there is no hindrance in holding.
Further, the front panel 75 may be formed in the same shape and size as the front wall portion 66 of the front inner panel 65 and may be directly attached to the front inner panel 65. Further, when the front panel 75 can be detached from the ice making machine main body 31 with one touch, the panel opening 78 may be omitted.
Furthermore, when the front panel 75 is not attached, a shutter member that can open and close the opening 72 may be added to the opening 72 formed in the front inner panel 65.
