Description

  The present invention relates to an attachment structure for temperature detection means disposed in an ice making section for generating ice blocks in an automatic ice making machine.

  An automatic ice maker that continuously manufactures a large amount of ice blocks is suitably used in facilities such as coffee shops and restaurants and other kitchens. As this automatic ice maker, ice making water is supplied from below to a large number of ice making chambers that open downward, and a spray type that continuously produces ice blocks, or ice ice water is allowed to flow down on ice making plates to produce plate-like ice blocks. There are various types, such as a flow-down type to manufacture.

  For example, in a jet type automatic ice maker, a mechanism chamber is defined in the upper part of a heat insulating box constituting the ice maker body, and an ice making mechanism for generating ice blocks is disposed in the mechanism chamber. As shown in FIG. 9, the ice making mechanism 20 includes an ice making chamber 28 having a partition plate 26 disposed vertically and horizontally on the lower surface of an ice making plate 24 horizontally disposed in the upper portion of the mechanism chamber 14, and opening downward. A large number of ice-making parts 22 defined in a grid pattern and an evaporation pipe 30 arranged meandering closely on the upper surface of the ice-making part 22 are provided. In addition, the ice making section 22 is inserted with a spacer 40 between a pair of mechanism section frames 18 and 18 (only one is shown) installed on the ceiling surface of the mechanism chamber 14, and the ice making section 22, the spacer 40, and the mechanism The screw 48 inserted into the part frame 18 is fastened with a nut 50 so that the evaporation pipe 30 provided on the upper surface of the ice making part 22 and the mechanism part frame 18 are arranged at a predetermined interval so as not to contact each other. Is done. Further, a water tray (both not shown) equipped with an ice making water tank and a circulation pump is pivotally supported on the mechanism frames 18 and 18 so as to be tiltable, and the ice making chambers 28 are opened by the water pan. Or it comes to close.

  When the ice making operation of the automatic ice making machine is started, when the ice making chambers 28 are closed by the water pan, small holes (not shown) drilled at positions corresponding to the respective ice making chambers 28 in the water pan. The ice making water in the ice making water tank is jetted and supplied to each ice making chamber 28 under the action of the circulation pump. At this time, the refrigerant is supplied to the evaporation pipe 30 by the operation of the refrigeration apparatus (not shown), the evaporation pipe 30 and the ice making unit 22 exchange heat, the ice making chamber 28 is forcibly cooled, and the ice making water is successively frozen. Thus, an ice lump having the same shape as the internal shape of the ice making chamber 28 is formed. Then, the ice making operation is switched to the deicing operation, and hot gas is supplied from the refrigeration unit to the evaporation pipe 30 to heat the ice making unit 22 and promote the removal of the ice block.

By the way, the automatic ice making machine performs the operation switching such as switching from the ice making operation to the deicing operation upon completion of ice making, or switching from the deicing operation to the ice making operation upon completion of the removal of the ice block, etc. (Temperature detection means) Based on the temperature of the ice making section 22 detected by Th, the control means (not shown) is used. The mounting structure of the thermistor Th to the ice making part 22 includes a plate-like holder member 80 having a holding recess 82 for the thermistor Th at one end and a mounting hole (not shown) at the other end. There is a configuration in which a screw hole of a plate member (not shown) welded and fixed to the upper surface of 22 is aligned with the mounting hole and fixed using a tapping screw 84 (see FIG. 9). Patent Document 1 also discloses a configuration in which the thermistor Th is held via a copper U-shaped sensor mounting plate 90 whose one surface is fixed by welding such as brazing (see FIG. 10). When the sensor mounting plate 90 is used, welding is performed with the open end of the sensor mounting plate 90 facing upward and the open end protruding from the upper surface of the ice making unit 22 with respect to the front wall surface 22a of the ice making unit 22. Then, while holding the thermistor Th at the closed end, the fixing screw 92 inserted through the through-holes (not shown) drilled in both open ends while the both open ends are in contact with each other has a cross-section L The thermistor Th is attached to the ice making unit 22 by being fastened to the L-shaped nut 94.
Japanese Utility Model Publication No. 4-32468

  The above-described attachment structure of the thermistor Th requires a work of welding the plate member or the sensor attachment plate 90 to the ice making portion 22 in order to fix the copper holder member 80 or the sensor attachment plate 90 to the ice making portion 22. The problem is that the man-hours increase and the cost increases. Further, since the copper employed as the material of the holder member 80 or the sensor mounting plate 90 is soft, it is easily deformed when the ice making unit 22 is cleaned, and the thermistor is deformed by the deformation of the holder member 80 or the sensor mounting plate 90. When Th is separated from the ice making section 22, there is a risk of causing ice making failure or ice making efficiency. Further, when the tapping screw 84 is used as a fixing screw, it is fixed while cutting the screw thread in the screw hole, so that a copper facet is generated, but the facet is completely removed due to complicated cleaning of the ice making part 22 and the like. There are difficulties that cannot be done. If the holder member 80 or the sensor mounting plate 90 is remounted several times due to the failure of the thermistor Th or the like, the screwing state of the tapping screw 84, the plate member or fixing screw 92, and the L-shaped nut 94 becomes loose, and the thermistor The fixed state of Th cannot be maintained. In this case, since the contact state of the thermistor Th deteriorates and causes ice making failure and ice making efficiency, the ice making part 22 itself must be replaced in order to replace the plate member and the sensor mounting plate 90. However, in this case, there is a problem that a large-scale work is required because a refrigerant pipe is attached / detached, a refrigerant is recovered, a welding work is performed on site, and the like.

  That is, the present invention has been proposed in order to suitably solve these problems inherent in the temperature detecting means mounting structure according to the prior art, and the mounting means for holding the temperature detecting means is attached. An object of the present invention is to provide an attachment structure for a temperature detection means that is easy and can reliably attach the temperature detection means to an ice making part even when it is repeatedly attached and detached.

In order to overcome the above-mentioned problems and achieve the intended purpose, the temperature detection means mounting structure according to the present invention comprises:
In the mounting structure of the temperature detection means in the automatic ice maker, in which the temperature detection means is attached to the ice making part spaced apart via the spacer on the mechanism part frame of the ice making machine body,
The attached portion provided in the attachment means is detachably attached to the attachment portion provided in the spacer, and the temperature detecting means is configured to contact the outer wall surface of the ice making portion.

  According to the temperature detecting means mounting structure according to the present invention, the attached portion provided in the attaching means is detachably attached to the attaching portion provided in the spacer so that the temperature detecting means is brought into contact with the outer wall surface of the ice making portion. Since it comprised, since the welding operation | work can be abbreviate | omitted in the case of attachment of an attachment means, work man-hours can be reduced and cost can be reduced. In addition, the engagement piece integrally formed with the spacer is configured to be engaged with the engagement hole provided in the attachment means so that the attachment state is not loosened by repeated attachment / detachment of the attachment means, so that the temperature can be reliably increased. The detection means can contact the ice making unit. Further, the mounting member is mounted on the spacer, and the engaging piece integrally formed on the mounting member is mounted by being engaged with the engaging hole provided in the mounting means, so that the mounting means can be repeatedly attached and detached. However, the temperature detecting means can be reliably brought into contact with the ice making section without loosening the mounting state. And since an attachment member is the structure attached to a spacer, there exists an advantage which can be attached irrespective of the height of a spacer.

  Next, a preferred embodiment of the temperature detecting means mounting structure according to the present invention will be described below with reference to the accompanying drawings. For convenience of explanation, the same reference numerals are used for the same components as those of the temperature detecting means mounting structure shown in FIGS. 9 and 10, and detailed description thereof is omitted. In the embodiment, the surface on which the temperature detecting means is attached in the ice making unit of FIG. 2 will be described as the front side.

  As shown in FIG. 2, in the automatic ice making machine 10 according to the first embodiment, a mechanism chamber 14 in which an ice making mechanism 20 for forming ice blocks is arranged is defined above the rectangular heat insulating box 12. In addition, an ice storage chamber 16 for storing ice blocks formed in the mechanism chamber 14 is defined adjacent to the lower portion of the mechanism chamber 14. The ice making mechanism 20 has a partition plate 26 arranged vertically and horizontally on the lower surface of an ice making plate 24 disposed horizontally in the mechanism chamber 14 so that a large number of ice making chambers 28 opening downward are defined in a grid pattern. An ice tray 22 (see FIG. 3), a water tray that is directly below the ice making portion 22 and that is integrally provided with an ice making water tank 34 for storing ice making water, and is pivotally supported by a support shaft 33. 32. The ice making unit 22 is made of a material having good thermal conductivity such as copper, and an evaporation pipe 30 through which a refrigerant or hot gas circulates from a refrigerating apparatus (not shown) is arranged in a serpentine shape on the upper surface thereof ( (See FIG. 4). Here, the ice making section 22 is provided with a cylindrical thermistor (temperature detecting means) Th at an appropriate position on the front wall surface 22a via a holder (attaching means) 60 described later (see FIG. 2). ). The water tray 32 and the ice making water tank 34 are horizontally positioned during the ice making operation and are held in parallel with the ice making section 22 to close the ice making chamber 28. During the ice removing operation, the water tray tilting mechanism 38 is used. The ice making chamber 28 is opened by being biased and tilted downward about the support shaft 33.

  On the ceiling surface of the mechanism chamber 14, a pair of mechanism part frames 18, 18 extending in the left-right direction with a required interval in the front-rear direction are disposed, and the ice making part 22, the water dish 32, and the water dish tilting mechanism are arranged. It functions as an installation base for various devices constituting the ice making mechanism 20 such as 38 (see FIG. 2 or FIG. 4). The ice making part 22 is inserted into the mechanism part frames 18, 18 by inserting a plurality of (four) spacers 40 between the ice making plate 24 on the upper surface and the lower surfaces of the mechanism part frames 18, 18. The ice making chamber 28 is attached in a substantially horizontal posture that opens downward using screws 48 and nuts 50 while being spaced apart from each other by a predetermined distance. The spacer 40 is provided with an insertion hole 42 that allows the screw 48 to be inserted at the center thereof. The material of the spacer 40 is a synthetic resin that has no problem in food hygiene and has heat insulation properties, such as an acetal resin. Is adopted. That is, between the through hole 24a drilled at an appropriate position close to the four corners of the ice making plate 24 and the hole 18a drilled at a position aligned with the through hole 24a in the mechanism frame 18, The insertion hole 42 of the spacer 40 is inserted in alignment, and the screw 48 is inserted into the through hole 24a, the insertion hole 42, and the hole 18a from below (the ice making part 22 side), and protrudes from the hole 18a. By tightening the nut 50 at the tip of the screw 48, the ice making part 22 is fixed in a state of being separated from the mechanism part frames 18 and 18 by the height of the spacer 40 (see FIG. 1 or FIG. 3). In addition, as the said nut 50, a thing with a flange is used suitably.

  Among the plurality of spacers 40, one of the spacers 40 located on the front side (the right side in FIG. 2) serves not only to determine the upper and lower arrangement positions of the ice making part 22 with respect to the mechanism part frame 18, but also the thermistor Th. An engagement piece (attachment portion) 44 is provided as a fixing means for fixing the holder 60 to be held. Hereinafter, in the first embodiment, the spacer 40 in which the engagement piece 44 is formed is particularly referred to as a first spacer 40A, and the other spacer 40 is referred to as a second spacer 40B. The second spacer 40B has a flange portion 40a extending radially outward on one end surface of a cylindrical main body portion having an insertion hole 42 formed in the center portion, and a shaft portion on the outer peripheral surface thereof. A plurality of ribs 40b projecting radially outward along the direction are formed. The plurality of ribs 40b have a tapered shape in which the protruding dimension decreases as the distance from the flange portion 40a increases (see FIG. 4). When the second spacer 40B is installed, the flange portion 40a is positioned on the mechanism frame 18 side.

  As shown in FIG. 1, the first spacer 40A is a dice-shaped member formed in a rectangular shape with respect to the second spacer 40B formed in a substantially cylindrical shape. The first spacer 40A is integrally provided with an engagement piece 44 serving as a fixing means for the holder 60 at a substantially central portion of one side surface (front surface) orthogonal to the upper and lower surfaces serving as the opening surfaces of the insertion holes 42. Is formed. The engaging piece 44 is composed of a pair of projecting pieces 46 and 46 projecting toward the front side, and each projecting piece 46 is symmetrically arranged with a predetermined distance from each other, and at the root part thereof. On the other hand, the front end portion is widened in a direction away from the other protrusion 46. In the engaging piece 44, the narrowed portions at the bases of both the protruding pieces 46 and 46 become holding parts 46 a and 46 a that hold the holder 60, and the width of the protruding parts 46 and 46 on the tip end side is widened. The portions function as restricting portions 46b and 46b that prevent the holder 60 from being detached. Here, the protruding dimensions of the holding portions 46 a and 46 a are set to be substantially the same as the thickness of the holder 60. Further, the projecting pieces 46 and 46 constituting the engaging piece 44 are elastically deformable in directions close to each other, and are always separated from each other, and when the holder 60 is inserted and removed. It functions like a so-called snap pin. The restricting portions 46b and 46b are tapered so as to converge from the base side (the holding portion 46a side) toward the tip side, thereby facilitating the attachment of the holder 60.

  In the state where the insertion hole 42 opened at the center of the first spacer 40A is aligned with the through hole 24a established in the ice making plate 24, the first spacer 40A is engaged with the front wall surface 22a of the ice making part 22 and the spacer 40A. It is set so that the surface on which the joining piece 44 protrudes is positioned on substantially the same vertical plane (see FIG. 3).

  The holder 60 is formed of a synthetic resin in a plate shape, and has an engagement hole (attachment portion) that can be externally inserted into the engagement piece 44 of the first spacer 40A at the upper end (one end) of the holder main body 62. ) 64 is opened, and at the lower end (the other end) of the holder main body 62, a concave portion 66 having a shape capable of holding a cylindrical thermistor Th is curved (see FIG. 1). The engagement hole 64 is set to have a lateral width narrower than a width between left and right end portions of the restricting portions 46 b and 46 b of the engagement piece 44, and a vertical height of the engagement hole 44. It is set approximately the same as the height. The recess 66 is formed in a substantially semi-cylindrical shape with its axis extending substantially horizontally, and the thermistor Th is held inside the recess 66 with its axis extending substantially in parallel. . The holder body 62 of the holder 60 is bent at a required angle θ in the direction in which the engagement hole 64 and the open end side of the recess 66 are close to each other in the middle of the engagement hole 64 and the recess 66. It is in the shape of a dogleg when viewed (see FIG. 3).

  The holder 60 is removably engaged with the engagement piece 44 of the first spacer 40A so that the holder 60 can be removed from the open end side of the recess 66 in the thermistor Th held by the recess 66. The part facing the direction is disposed in contact with (contact with) the front wall surface 22 a of the ice making unit 22. In addition, a gap between the recess 66 of the holder 60 and the thermistor Th is filled with a filler 68 such as a silicone resin having good thermal conductivity and curable properties. The filling material 68 is hardened in a state where the thermistor Th is in contact with the ice making portion 22, thereby making it difficult to separate the thermistor Th from the front wall surface 22a of the ice making portion 22. The contact state is made more suitable. In particular, by adopting a silicone resin as the filler 68, when replacing the thermistor Th, the filler 68 can be easily peeled off from the thermistor Th, so that the replacement operation is not hindered.

  In the ice making operation, in the ice making operation, the ice making unit 22 is forcibly cooled by supplying a refrigerant from the refrigeration apparatus to the evaporation pipe 30 and driving the circulation pump 36 disposed in the water tray 32. Ice making water is supplied from the ice making water tank 34 to the ice making chamber 28 through a small hole (not shown) of the water tray, and ice blocks are generated in the ice making chamber 28. On the other hand, in the deicing operation, the ice blocks generated in the ice making chamber 28 are supplied with hot gas from the refrigeration circuit to the evaporation pipe 30 to heat the ice making unit 22 while the ice making water supply is stopped. The ice blocks are separated from the ice making chamber 28 and stored in the ice storage chamber 16.

  Further, when the thermistor Th detects the ice making completion temperature of the ice making unit 22 in which ice blocks having a predetermined shape are generated in all ice making chambers 28 as the ice making operation proceeds, the control means (not shown) makes ice making. When the thermistor Th detects a temperature rise (deicing completion temperature) of the ice making unit 22 due to the switching from the operation to the deicing operation, and the deicing of the ice block from the ice making chamber 28 is completed by the deicing operation, the control means Is set to switch from deicing operation to ice making operation. As described above, in the automatic ice making machine 10, various devices such as the ice making mechanism 20 and the refrigeration apparatus are controlled to perform predetermined operations by the control unit based on the temperature detection of the ice making unit 22 by the thermistor Th. .

[Operation of Example 1]
Next, the operation of the temperature detector mounting structure according to the first embodiment will be described. When the engaging hole 64 formed in the holder 60 is fitted to the engaging piece 44 of the first spacer 40A, the projecting pieces 46 and 46 are deformed in a direction approaching each other, and the restricting portions 46b and 46b are formed. By contracting the mounting portion 64, the mounting of the engaging hole 64 set narrower than the width of the restricting portions 46b and 46b is allowed, and when the holder 60 arrives at the holding portions 46a and 46a, the restricting portion 46b again. 46b are expanded to hold the opening edge of the engagement hole 64, so that the detachment of the holder 60 is restricted and fixedly held. That is, the attachment structure using the engaging action of the engaging piece 44 and the engaging hole 64 can detachably mount the holder 60 to the engaging piece 44 of the first spacer 40A. As in the case of attaching the screw, the attachment state of the holder 60 is not loosened even by repeated removal of the holder 60. Further, even when the holder 60 is touched when the ice making unit 22 is cleaned, the first spacer 40A is not deformed or moved, and the contact state of the thermistor Th with the front wall surface 22a of the ice making unit 22 can be suitably maintained. . Therefore, it is possible to avoid problems such as poor ice making and reduced ice making efficiency due to poor contact between the ice making part 22 and the thermistor Th. Even if the engagement piece 44 is damaged, it is sufficient to replace only the first spacer 40A. Therefore, it is easy to replace the existing device, and the plate member and sensor mounting of the thermistor Th described above are good. As in 90, since it is not necessary to replace the entire ice making unit 22 due to breakage, maintenance work can be saved and economic efficiency can be improved.

  Since the spacing between the restricting portions 46b, 46b and the surface of the first spacer 40A on which the engagement piece 44 is disposed is substantially the same as the plate thickness of the holder 60, the open end of the recess 66 in the holder 60 is connected to the open end. When the holder 60 is attached to the engagement piece 44 with the engagement hole 64 aligned with the front end surface 22a of the ice making part 22 facing, the holder 60 is securely fixed. Further, since the holder main body 62 is bent, the holder main body 62 expands, and the open end of the concave portion 66 can elastically contact the front wall surface 22 a of the ice making unit 22. That is, the thermistor Th held in the concave portion 66 is in a pressing state in the direction toward the front end surface 22a of the ice making unit 22, and can suitably come into contact with the front end surface 22a. It can be detected accurately. In this way, the holder 60 is always energized with the concave portion 66 toward the front wall surface 22a of the ice making unit 22, and is a resin molded product and hardly deformed. Therefore, when the automatic ice making machine 10 is moved, The contact state of the thermistor Th is also maintained well by vibration of the nozzle or contact during cleaning. Further, when the holder 60 is mounted, the thermistor Th and the recess 66 and the ice making part 22 are filled with the filler 68 and hardened and fixed, so that it is difficult to separate the thermistor Th from the ice making part 22 ( (See FIG. 3).

  In this way, the engagement piece 44 as an attachment portion of the holder 60 that holds the thermistor Th is integrally formed on the first spacer 40 </ b> A, and the holder 60 is engaged with the engagement hole 64 formed in the holder 60. By attaching the holder 60 to the holder 60, it is not necessary to perform the welding work as in the prior art, and the number of work steps can be omitted and the cost can be reduced. Moreover, since the welding operation for the ice making part 22 is only a welding process for brazing the evaporating tube 30 to the upper surface of the ice making part 22, the welding operation is only performed on the same plane, so that the welding operation is automated. The transition can be made easily. In addition, since no metal member such as a screw is used for the attachment of the holder 60, it is possible to reduce the trouble of taking measures such as rust prevention in the mechanism chamber 14 in a wet and severe corrosive environment. Reliability is improved as a structure.

  The first spacer 40A is interchangeable with a spacer in an existing automatic ice making machine. That is, when the thermistor of the existing automatic ice making machine is replaced, the existing spacer is replaced with the first spacer 40A of the first embodiment set to the same height as the existing spacer, and the thermistor Th is used by the holder 60 of the first embodiment. If it is comprised so that can hold | maintain, the favorable effect which the mounting structure of the 1st spacer 40A mentioned above and the holder 60 show | plays can be acquired.

  FIG. 5 is a schematic perspective view showing the attachment structure of the thermistor (temperature detection means) Th according to the second embodiment in an exploded state, and FIG. 6 is a schematic perspective view showing the state in which the thermistor Th is attached to the ice making unit 22. is there. In the first embodiment, the configuration in which the engagement piece 44 is formed integrally with the spacer 40 as the mounting portion of the holder 60 has been described. However, in the second embodiment, the mounting member 52 separate from the spacer 40 is used as the mounting portion. The spacer 40 is configured to be attached. The spacer 40 of the second embodiment has the same configuration as the second spacer 40B described in the first embodiment, and the configuration of the mechanism frame 18, the ice making unit 22, the holder 60, and the like is the same as that of the first embodiment. Description is omitted.

  The mounting member 52 is a rectangular member made of a synthetic resin similar to the spacer 40, and is set to be shorter than the height of the spacer 40, and has a cross-sectional shape orthogonal to the axis of the spacer 40 at the center thereof. A substantially matching fitting hole 52a is penetrated, and the spacer 40 can be inserted into the fitting hole 52a (see FIG. 5). That is, in a state where the spacer 40 with the mounting member 52 fitted externally faces the through-hole 24a of the ice making section 22, the above-mentioned through the through-hole 24a, the insertion hole 42 of the spacer 40, and the hole 18a of the mechanism section frame 18 By inserting the screw 48, the mounting member 52 is disposed on the upper surface of the ice making unit 22 in a state of being attached to the spacer 40 (see FIG. 6). At this time, the plurality of ribs 40b protrudingly formed on the spacer 40 are fitted into the fitting holes 52a, and the rotational movement of the spacer 40 in the circumferential direction is restricted. In addition, since the rib 40b of the spacer 40 has a tapered shape, the mounting member 52 that is externally fitted to the spacer 40 is restrained by the upper surface of the ice making part 22, and the movement is restricted in the vertical direction. An engaging piece 54 serving as a fixing means for the holder 60 is integrally formed on the mounting member 52 at a substantially central portion of one side surface (front surface) orthogonal to the upper and lower surfaces serving as the opening surfaces of the fitting holes 52a. Is formed. The engagement piece 54 is the same as the engagement piece 44 described in the first embodiment, and engages with an engagement hole (attached portion) 64 formed in the holder 60, so that the concave portion of the holder 60 is engaged. The thermistor Th held by 66 is attached in a state where the thermistor Th is in contact with the front wall surface 22 a of the ice making unit 22.

  As described above, the mounting portion of the holder 60 is used as a mounting member 52 separate from the spacer 40, and the mounting member 52 is mounted on the spacer 40, thereby eliminating the welding work when mounting the holder 60. Although the same effect as 1 is produced, in particular, according to the configuration of the second embodiment, it is possible to share the mounting member 52 corresponding to the spacers 40 having different lengths depending on the models and the like. In the existing automatic ice making machine, the diameter dimension of the spacer is basically made common, and the mounting member 52 can be mounted regardless of the length of the spacer. Therefore, it is necessary to prepare a plurality of mounting members 52. And the workability of replacement can be improved. As described above, even with an existing automatic ice making machine, the mounting structure of the thermistor Th can be easily shifted to the configuration of the second embodiment, so that the preferred effect of the mounting structure of the thermistor Th according to the second embodiment is achieved. Can be enjoyed.

(Change example)
In the first embodiment or the second embodiment, as the attachment structure of the holder 60, the engagement pieces 44 and 54 formed integrally with the spacer 40A or the attachment member 52 and the engagement hole 64 of the holder 60 are engaged and fixed. However, another structure may be used as the attachment structure of the holder. As shown in FIG. 7, the mounting structure of the thermistor (temperature detecting means) Th according to the modified example includes a screw hole 45 instead of the engaging piece 44 as the mounting portion of the spacer 40A described in the first embodiment. A mounting hole 65 is drilled as a mounted portion of the holder 60 corresponding to the above, and the screw hole 45 and the mounting hole 65 are aligned, and the mounting screw 70 is screwed into the screw hole 45, whereby the concave portion of the holder 60 is The thermistor Th held by 66 can be fixed in a state in which the thermistor Th is in contact with the front wall surface 22a of the ice making unit 22. Other configurations are the same as those in the first embodiment. As shown in FIG. 8, the mounting structure of the thermistor (temperature detection means) Th according to another modification is replaced with the screw hole 55 instead of the engaging piece 54 of the mounting member 52 as the mounting portion described in the second embodiment. The mounting hole 65 is drilled as a mounted portion of the holder 60 corresponding thereto, the screw hole 55 and the mounting hole 65 are aligned, and the mounting screw 70 is screwed into the screw hole 55. The thermistor Th held in the recess 66 of the holder 60 can be fixed in a state where the thermistor Th is in contact with the front wall surface 22 a of the ice making unit 22. Other configurations are the same as those in the second embodiment. According to the mounting structure of the thermistor Th according to the modified example or another modified example, the welding operation can be omitted when the holder 60 is mounted, and an existing holder configured to fix the holder to the ice making unit 22 with a screw is used as it is. There are advantages available.

  As another modification, the attachment member and the holder may be integrally formed. In this case, the fitting hole of the attachment member becomes the attached portion, and the main body of the spacer becomes the attachment portion.
