Abstract

<P>PROBLEM TO BE SOLVED: To provide a water pan for a fountain type ice maker having strength endurable at forced separation time from an ice making chamber, and having strength of not receiving undesirable deformation at molding time. <P>SOLUTION: Two strips of horizontal ribs 22a and 22b extending over the whole width of the water pan so as to sandwich a plurality of linearly aligned clearance holes 15, are arranged in a part in the vicinity of a water pan tip part 10b for receiving operation force of a water pan tilting mechanism on the reverse of the water pan 10. Since the horizontal ribs extend from the reverse of the water pan up to a plane for regulating an under surface of the water pan, the strength of the water pan increases, and the occurrence of strain is eliminated at molding time so that clearance between the water pan existing in a horizontal closing position and the ice making chamber is uniformly held at a proper distance. The water pan tilting mechanism can be simplified according to an increase in the strength. This water pan may have a plurality of vertical ribs 23a to 23d for connecting the mutual horizontal ribs, and these vertical ribs can also extend from the reverse of the water pan up to the plane for regulating the under surface of the water pan. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice making mechanism in a fountain type ice making machine, and more particularly to an improvement in a water tray in the ice making mechanism. 2. Description of the Related Art A fountain type in which ice making water is jetted upward from a water tray disposed below a large number of ice making compartments that open downward to continuously produce ice cubes (ice blocks). Ice machine,
It is widely used in facilities such as coffee shops and restaurants and other kitchens. In this fountain type ice making machine, an ice making mechanism unit including a large number of components such as an ice making chamber, a water tray, an ice making water tank, an actuator motor for tilting the water tray, and a cam arm is mounted above the inside of the box-shaped housing. It is arranged via a frame. That is, an ice-making chamber in which a number of small ice-making chambers that open downward are defined horizontally below a mounting frame provided above the inside of the housing, and an ice-making chamber is provided immediately below the ice-making chamber. A water tray integrally provided below with an ice making water tank for storing water is pivotally supported in a cantilever manner on a water tray bracket suspended from a mounting frame via a support shaft. [0003] An evaporating tube for circulating the refrigerant during the ice making operation and forcibly cooling the ice making chamber is closely arranged in a meandering manner on the upper surface of the ice making chamber, and ice making water is repeatedly injected and supplied from a water tray into each ice making chamber. Thus, the ice making chamber is configured to generate ice cubes. Further, the mounting frame is provided with a pair of cam arms on a cam shaft rotatably supported by a bearing member suspended from the mounting frame, and an actuator motor is provided via a motor bracket. By rotating the cam arm forward and backward by the actuator motor, the water tray is tilted between the inclined open position and the horizontal closed position with respect to the ice making chamber by the action of a spring and a cam. [0004] On the other hand, a plurality of injection holes are formed on the upper surface of the water tray so as to spray and supply ice making water to each of the above-mentioned ice making chambers when the water tray is in the horizontal closed position. In the vicinity thereof, a return hole for returning return water not frozen in the ice making chamber to the ice making water tank is formed. Each of the injection holes communicates with a common water supply passage in the water tray, and ice making water is supplied through the water supply passage. The return water that has entered each return hole falls into the ice making water tank via the guide member or without the guide member. [0005] During the ice making operation, the water tray is in the horizontal closed position, faces the ice making chamber from below, and supplies ice making water to each of the ice making compartments. When the ice making is completed, the water tray is generated in each ice making compartment. The ice cubes are not separated individually, but the ice cubes are connected to each other through the lower surface of each ice cube, that is, through a flange-like thin overhang formed on the ice cube surface on the water dish side,
It is a plate-shaped ice cube group as a whole. During deicing operation,
The plate-shaped ice cubes fall on a water dish, and then slide down into an ice storage, where they are separated into individual ice cubes by an impact. However, in practice, it is known that ice cubes are not properly separated and several ice cubes exist in a state of being connected to each other at their flange-shaped portions. Since the thickness of the portion is uneven, it has been found that the impact concentrates on the thin portion and separates there first, resulting in plate-like ice cubes. The water tray is manufactured from a synthetic resin by molding. The present inventors have carefully compared the dimensions of each part in the water tray design drawing with the actual dimensions of each part of the water tray immediately after molding. And found that there are subtle differences. And, based on the presumption that this difference may be derived from the distribution of the stress received by the water dish during molding, as a result of trying to analyze the stress received by the water dish, the tip part of the water dish, That is, it was found that stress was concentrated on the water plate portion far from the tilt center when the water plate was tilted from the horizontal closed position to the tilt open position. Therefore, focusing on the structure of the conventional ice making mechanism, in particular, not only the water tray itself but also a water tray drive mechanism for pivoting the water tray between the horizontal closed position and the inclined open position, As described above, the mechanism includes a pair of cam arms provided on a cam shaft, an actuator motor provided via a motor bracket, and the pair of cam arms being rotated forward and reverse by the actuator motor. The water dish is tilted between the inclined open position and the horizontal closed position with respect to the ice making chamber by a cam action on the tip of the dish. The water tray is received by the water tray tip when the pair of cam arms act on the left and right receiving portions of the water tray tip to forcibly separate the water tray from the ice making chamber from the horizontal closed position to the inclined open position. Designed to withstand stress. However, since the dish is actually distorted, the stress received by the tip of the dish when separated from the ice-making chamber and the stress received by the tip of the dish when forming the dish are unbalanced. Therefore, in other words, it is considered that since the latter stress is larger than the former, the water dish is deformed. [0008] The inventors of the present invention considered the basic design concept of the water tray, and found that the conventional water tray has a cam action at both the left and right ends of the tip. Therefore, considering one side of the tip of the water dish, the design stress value received there was set relatively low, and the water dish actually had a structure that could withstand such stress value It has been found that the above-mentioned imbalance has occurred. Accordingly, it is a primary object of the present invention to provide a fountain type ice maker having not only strength enough to withstand forced separation from an ice-making chamber, but also strength not to cause undesired deformation during molding. Is to provide a water dish. [0010] In order to achieve this object, the present invention according to claim 1 has a water tray tilting mechanism.
In a water tray for a fountain type ice maker, the water tray is tilted so as to face the ice making chamber during the ice making operation, and is tilted to an inclined open position separated from the ice making chamber during the deicing operation. An injection hole for injecting ice making water toward each ice making compartment of the ice making room, a return hole for returning non-freezing water not frozen in each of the ice making compartments to the ice making water tank, and water on the water tray. A plurality of escape holes are provided at least near the distal end of the water dish to escape the water into the ice making water tank, and the entire width of the water dish is sandwiched between the escape holes on the back surface of the water dish. Two horizontal ribs extending over the water tray, the horizontal ribs extending from the back surface of the water tray to a plane defining the lower surface of the water tray, and near the horizontal ribs of the water tray, A receiving portion that engages with a component of the water tray tilting mechanism is provided. It is characterized. Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. Further, as will be understood from the following description, the present invention is not limited to this embodiment, and various modifications are possible. FIG. 1 shows a water tray 10 according to one embodiment of the present invention.
1 is an exploded view of an ice making mechanism section 1 of an ice making machine in which is incorporated. Needless to say, the ice making mechanism 1 is installed in a housing (not shown) of the ice making machine. Above the inside of the housing having a substantially box shape, a mounting plate 2 formed in a rectangular dish shape is mounted horizontally at horizontal flange portions 2a and 2b on the left and right sides by a known method. In addition to the ice making chamber 3, the water tray 10, and the ice making water tank 4, the ice making mechanism 1 including the actuator motor 5, the cam arm 6, the spring 7, and the like are mounted on the mounting frame 2. Since there is no direct relationship with the gist of the present invention, a brief description will be given. However, a projection (not shown) having a screw hole is provided on the lower surface of the mounting frame 2 so that the ice making chamber 3 can be viewed from below. The ice making chamber 3 can be mounted on the mounting frame 2 by passing a bolt (not shown) and tightening the bolt into the above-described screw hole.

The pin 8 shown attached to the support brackets 8a and 8b in FIG.
d (only one side is shown) is rotatably inserted. That is, the water tray 10 is pivotally supported in a cantilevered state below the mounting frame 2 and directly below the ice making chamber 3 in a proper posture via the pins 8d. The water tray 10 is integrally provided with an ice making water tank 4 for storing a required amount of ice making water below the water tray 10.
A pump motor 4a is attached to the outside of the bottom of the tank 4, and the ice making water sucked by the motor 4a is discharged and supplied to the water tray 10, and is drilled in the water tray 10 as described later. From each of the injection holes (not shown in FIG. 1), the injection is supplied correspondingly into the ice making chamber. Further, a return hole (not shown) communicating with the ice making water tank 4 is formed in the water tray 10 in close proximity to each of the injection holes, and the non-freezing water that has not been frozen in each of the ice making chambers is returned. The water is collected in the ice making water tank 4 through the hole and is supplied to the circulation again. The configuration for this will be described later in detail. Next, as understood from FIG. 1, a U-shaped fender 5a is provided at a position deviated rightward on the front wall 2c of the mounting frame 2 in such a manner as to cover the turning trajectory of the cam arm 6 from above. Are attached by screws 5b. A mounting base 5c of an actuator motor 5 for driving the water tray 10 to open and close is mounted on a front end face of the fender 5a by screws 5d. On the other hand, the cam arm 6 is connected to a rotating shaft of an actuator motor 5 (not shown) by a boss 6a at a lower end thereof. Further, a tension coil spring serving as a spring 7 is elastically interposed between a pin 6 b protruding from the distal end of the cam arm 6 and a pin 10 a protruding from the front side surface of the corresponding distal end of the water tray 10. The ice tray 3 is closed from below by always raising the water tray 10 to the horizontal closed position. Also, the cam surface 6 of the cam arm 6
Although not shown, d can be brought into contact with the upper surface of the water tray 10, and during the deicing operation, the actuator motor 5 rotates to tilt the water tray 10 downward. It is configured to be forcibly separated to the inclined open position. Next, the structure of the water tray 10 will be described in more detail. FIG. 2 shows the water tray 10 at an inclined open position separated from the ice making chamber 3 described above. A water tray 10 having an ice making water tank 4 capable of storing a predetermined amount of ice making water
Is pivotally supported by the above-mentioned pin 8d, and a drain pan 11 for guiding the drainage during deicing to the outside so as not to be mixed into an ice storage (not shown) is provided below the pin 8d. As described above, the ice making water tank 4 and the water tray 10 are in a horizontally closed position that is horizontally positioned during the ice making operation and is held in parallel with the ice making chamber 3 (see FIG. 1). Each of the ice making chambers of the ice making chamber 3 is tilted clockwise about the pin 8d by being urged by the water tray opening / closing mechanism including the actuator motor 5, the cam arm 6, the spring 7, and the like described with reference to FIG. It is in the inclined open position to open. FIG. 2 shows the water tray 10 in a horizontal open position. On the surface of the water tray 2, injection holes 12 for injecting ice making water toward each ice making chamber are arranged in a grid pattern at a position aligned with the axis of each ice making chamber when in the closed position. In the embodiment, two return holes 13 are formed above and below each of the injection holes 12. In addition,
For simplicity of the drawing, the injection holes 12 are simply indicated by black circles, and the return holes 13 are typically indicated by only white circles above and below the one injection hole 12; FIG. 3, which shows the water tray 10 in position and closing the ice making compartment 3, better illustrates the arrangement of these jet holes 12 and return holes 13. Needless to say, the injection holes 12
The size of the return hole 13 is not described on a scale representing the actual size. A distribution pipe (not shown) communicating with the injection hole 12 but not with the return hole 13 is provided on the back surface of the water tray 10 as described later. The pump 4a is provided so that ice making water is pressure-fed to each injection hole 12 through a distribution pipe, and can be sprayed therefrom to a corresponding ice making chamber. Then, the non-freezing water that has not been frozen in the ice making compartment is recovered to the ice making water tank 4 through the return hole 13 and is again injected into the ice making compartment by the pump 4a. As shown clearly in FIG. 3, a plurality of rectangular relief holes 14 and circular relief holes 15 are provided on the surface of the water tray 10 at positions around the water tray which are separated from the injection holes 12 and the return holes 13. Water supply pipe 16 (Fig. 2)
A part of the washing water 17 sprayed from the water and the water sprayed as the ice making water are collected in the ice making water tank 4. In this fountain-type ice making machine, when the ice making operation proceeds and ice cubes of a sufficient size are generated in the ice making compartment, an ice making completion detection sensor (not shown) detects this state and performs the deicing operation. The tilting of the water tray 10 and the ice making water tank 4 is started by the water tray opening / closing mechanism described above, and the water tray 10 in the closed position is moved to the ice making chamber 3 where ice cubes are generated.
2 to the open position in FIG. Also,
As is well known in the art, hot gas is supplied to the evaporator tubes to melt the surface of ice cubes in each ice making chamber and discharge the ice cubes into an ice storage (not shown). However, water dish 1
Since the residual ice 18 generated by the forced separation of the water tray 10 from the ice making chamber 4 is firmly adhered to the surface of the ice tray 4 as shown in FIG. 18 is supplied from a water supply pipe 16 with tap water at normal temperature to the surface of the water tray 10 as washing water 17, whereby the residual ice 18 is melted and washed, and the surface of the water tray 10 is returned to a smooth state. The washing water 17 sprayed from the water supply pipe 16 for this purpose cleans the residual ice 18 adhered to the surface of the water tray 10, and then partially passes over the open lower end 10 b of the water tray 10 to form ice water. The water enters the tank 4 and a part of the water enters the ice making water tank 4 through the above-described escape holes 14 and 15 and the return hole 13, and the washing water 17 overflowing therefrom is discharged from the drain pan 11 (not shown). ) To be discharged outside the machine. Water is supplied from the water supply pipe 16 even after the washing of the residual ice 18 has been completed and the water tray 10 has been restored from the open position to the closed position, and a part of the water has passed through the return hole 13 and a part of the water has escaped. The ice making water can be stored in the ice making water tank 4 through the holes 14 and 15 as ice making water for the next ice making operation cycle. FIG. 4 shows a water dish 10 according to one embodiment of the present invention.
Is shown in more detail, and FIG. 5 shows a cross section along line VV in FIG. In FIG. 4, the open lower end 10b of the water tray 10 is shown on the upper side. The water supply passage 20 for supplying ice making water to each of the jet holes 12 is provided with the water tray 1.
0 from its base end 10c side to the open lower end 10b
And a branch pipe portion 20b extending left and right from an intermediate position of the main pipe portion, and a pair of branch pipe portions 20b extending from the same main pipe position are arranged along the rows of the injection holes 12. The pair of return holes 13 sandwiching each of the injection holes 12 is formed at a position not in fluid communication with the branch pipe portion 20 b of the water supply passage 20. In order to reinforce the water tray 10, various reinforcing ribs are integrally formed at appropriate positions on the back surface of the water tray. That is, in one embodiment of the present invention, first,
Four vertical ribs 21a, 21b, 21c, 21d extending vertically from the c side toward the first pair of branch pipe portions 20b are provided. From the middle position of the leftmost vertical rib 21a, the horizontal rib 2 is short to the left wall of the water tray 10 in FIG.
1a ', 21a ". These ribs 21
a ′, 21a ″, 21a, 21b, 21c, 21d are
As can be seen from FIG. 5, the water tray 10 extends almost to the bottom of the water supply passage 20 in the thickness direction. Furthermore, the water tray 10 is located near the open lower end 10b.
The two long transverse ribs 22a, which are arranged so as to approach the relief holes 15 of the row and sandwich the relief holes 15 from above and below in FIG.
22b extends over the entire left and right width of the water tray 10, and four short vertical ribs 23a to 23d connecting the horizontal ribs 22a and 22b to each other are provided so as not to intersect with the escape hole 15. Further, from the branch pipe portion 20b defining the injection hole 12 arranged closest to the open lower end 10b of the water tray 10, short vertical ribs 24a to 24h to the above-mentioned horizontal rib 22a are formed.
Preferably, 24d extends. Vertical ribs 23a-2
The 3d and the vertical ribs 24a to 24d correspond to each other on a one-to-one basis and extend linearly. The height of the vertical ribs 24a to 24d may be about の of the height of the water supply channel 20, but the height of the horizontal ribs 22a,
22b and the vertical ribs 23a to 23d substantially extend to a plane defining the lower surface of the water dish 10, and therefore, it can be seen that the strength of the water dish 10 is increased in these portions as compared with the conventional water dish. FIGS. 8 and 9 show another example of a water tray corresponding to FIGS. 4 and 5 showing one embodiment of the present invention. Briefly, FIG. 8 and FIG. 9 correspond to the horizontal rib 22b in the present invention. The horizontal rib 30b extends over the entire width of the water tray in the left and right directions, while the other horizontal rib 30a terminates at a position relatively close to the left and right walls of the water tray 40. The vertical ribs corresponding to the short vertical ribs 23a to 23d and the vertical ribs 24a to 24d in the embodiment are not divided by the horizontal ribs 30a but are continuous vertical ribs 31a to 31d.
It has become. In addition, with respect to the height of the rib, the divided horizontal rib 30a is relatively high, but the other ribs 30
b and 31a to 31d are low similarly to the vertical ribs 32a to 32d corresponding to the vertical ribs 21a to 21d in the embodiment of the present invention. Further, in one preferred embodiment, the water dish 10
Solid receiving portions 27a and 27b for securely receiving the pins 10a (only one pin is shown in FIG. 1) protruding from the left and right sides of the open lower end 10b, which is the leading end portion, are also integrally formed on the lower surface of the water tray. Have been. In one embodiment, the pin 10a is a male screw having a threaded portion, and each receiving portion 27
A and 27b are formed with screw holes into which male screws are screwed. In the embodiment, two receiving portions 27a and 27b are formed. However, when only one spring 7 is used, one receiving portion may not be used or may not be provided. The positions of the left and right receiving portions 27a and 27b are vertically displaced in FIG. 4, but this displacement is caused by the fact that the cam arm 6 is provided with the boss 6a for receiving the output shaft of the actuator motor 5, This is caused because the spring 7 is designed to be hardly affected by the influence. Further, in one embodiment according to the present invention, the lateral rib 22a side of the branch pipe portion 20b communicating with the injection hole 12 arranged closest to the open lower end 10b of the water tray 10 has the most in FIG. As best shown, a guide member 25 surrounding the return hole 13 is provided.
The details of No. 5 are disclosed in Japanese Utility Model Application Laid-Open No. 61-200566 of the present applicant. In addition, in the ice making room 3 of FIG. 6, it turns out that the ice making small room 3c is defined by the horizontal partition plate 3a and the vertical partition plate 3b inserted so that it may mutually cross. Reference numeral 26 denotes a refrigerant evaporating tube which is arranged in a meandering manner in close contact with the back surface of the ice making chamber 3. Next, the operation of the fountain type ice maker provided with the above-mentioned water tray 10 will be described with particular emphasis on the operation of the water tray 10. During the ice making operation, the water tray 10 is placed in each of the ice making chambers 3a of the ice making chamber 3. The ice making water is jetted from each of the jet holes 12 opened on the surface of the water tray toward each of the ice making chambers 3a. Most of the uniced water enters the return hole 13 and is returned to the ice making water tank 4 from there. The water supply pipe 4 is provided by a pump motor 4a provided outside the bottom of the tank 4.
After b, it is circulated again to the ice making chamber. A part of the uniced water is returned to the ice making water tank 4 through the escape holes 14 and 15. At this time, since the row of the relief holes 15 near the open lower end 10b of the water tray 10 is sandwiched between the horizontally extending (high) horizontal ribs 22a and 22b, the return water passing through the relief holes 15 is formed. Is efficiently returned to the ice making water tank 4 by being guided by the lateral ribs 22a and 22b. When the ice making operation is completed and the operation is switched to the deicing operation, the actuator motor 5 is operated to rotate the cam arm 6 so that the water tray 10 is moved by the cam surface to the spring 7.
By pressing downwardly against the force of (3), it is forcibly separated from the ice making chamber 3 and moved to the inclined open position shown in FIG. Since the residual ice 18 adheres to the surface of the water dish 10, the cleaning water 17 is injected from the water supply pipe 16 to melt the residual ice 18. Through the rectangular relief holes 14 opening at the left and right ends of the water tray surface, partly through the relief holes 15 near the open lower end 10b of the water tray 10, and the rest through the water tray 10 And enters the ice making water tank 4 beyond the open lower end 10b. Again,
The return water that has passed through the escape hole 15 is guided by the horizontal ribs 22a and 22b, and is efficiently returned to the ice making water tank 4. Then, to start the ice making operation, the water tray 10 is returned to the horizontal closed position, but from the water supply pipe 16, the ice making water tank 4 is full to store the ice making water used in the next ice making cycle in the ice making water tank 4. Until the water supply is reached, water supply as ice making water is still performed. Also in this case, the water supply is returned to the ice making water tank 4 in substantially the same manner as the above-mentioned washing water. Then, the ice making operation starts again. In the water tray 10 according to the embodiment of the present invention, unlike the conventional one, the rib 22a extends over the entire width of the water tray 10, and only the ribs 22a and 22b are used. Since the ribs 23a to 23d also have a height almost extending to a plane defining the lower surface of the water tray 10, it is confirmed that the ribs 23a to 23d have a very rigid structure and do not generate distortion during molding. Therefore, since the lower surface of the ice making chamber 3 and the upper surface of the water tray 10 are accurately held in parallel with each other, as can be understood from FIG. It will be joined by the thin flange part 28a of a substantially uniform thickness,
The individual ice cubes 28 are reliably separated by the impact when falling onto the water tray 10 during the deicing operation or the impact when the water tray 10 slides down and falls into the ice storage. The water tray 10 is provided with a plurality of vertical ribs 23a to 23d for connecting the two horizontal ribs 22a and 22b to each other.
２３23d also extends to the plane defining the lower surface of the water tray 10.
Extending from the back surface of the water tray 10, the strength of the water tray 10 is further increased. Further, with the increase in the strength of the water tray 10 due to the use of the horizontal ribs 22a and 22b, or the horizontal ribs 22a and 22b and the vertical ribs 23a to 23d, a cam shaft required in the conventional water tray tilting mechanism, It is possible to eliminate one of the cam arms and the like, so that the water tray tilting mechanism is simplified, so that not only the maintenance is facilitated but also the assembling time of the ice making machine is shortened and the manufacturing cost is reduced. Moreover, since the possibility of the parts of the water tray tilting mechanism falling into the ice cubes of ice cubes, which is also food, is reduced as much as possible, not only the improvement of hygiene but also the possibility of harm to the human body is anticipated. Can be prevented. As can be seen from the above description, claim 1
In the water tray of the fountain type ice maker according to the present invention described in (1), particularly, on the back surface of the water tray, a plurality of escape holes are sandwiched between the water tray tilting mechanism and a portion near the tip end of the water tray. Two horizontal ribs extending over the entire width of the dish are provided, and the horizontal ribs extend from the back surface of the water dish to a plane defining the lower surface of the water dish, so that distortion or the like occurs during the formation of the water dish. As a result, the gap between the water tray in the horizontally closed position and the ice making chamber is kept uniformly at an appropriate distance. Therefore, when ice making is completed, the thickness of the flanges or overhangs of the ice cubes that are joined to each other also becomes uniform, and the ice cubes that were joined to each other at this flange are easily separated into individual ice cubes by the impact of falling. can do. Further, since the height dimension of the horizontal rib is large, the washing water or the supply water passing through the escape hole interposed between the horizontal ribs is guided by the horizontal ribs after exiting, and is efficiently returned into the ice making water tank. be able to.
