Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tableware dipping tank for separating food and drink adhering to tableware by immersing dirty tableware in immersion water.

[0002]

2. Description of the Related Art A large amount of tableware is washed in a place where the food service industry is operated, such as a restaurant, but it is very difficult to manually drop grains of rice stuck to the tableware, and the tableware has oil and fat content. , Protein content, fiber content, seasoning content, etc. will adhere, and the cleaning water will be soiled quickly during cleaning unless these are removed.Besides, it takes longer to clean the dishes, so wash the dishes. Prior to the above, tableware dipping tanks have been widely used to facilitate the separation of soiled dishes from the dishes by soaking the dishware in the immersion water.

On the other hand, a dishwasher holds a large number of dishes in a rack and performs washing on a rack-by-rack basis. The processing capacity per rack is 1 to 2 minutes including washing and rinsing. Although it is about a degree, the conventional tableware dipping tank requires dipping for about 5 minutes. Therefore, in order to continuously and efficiently perform the dirt separation work by the dish immersion tank and the washing work by the dishwasher, a large amount of dishes that can be held by 3 to 5 racks can be processed at one time. It is necessary to prepare a dish-washing tank of a suitable size for one dishwasher. In this case, the installation space of the equipment becomes large, and the layout of the store is greatly affected.

Under these circumstances, tableware dipping tanks have been developed for enhancing the dirt separation performance. Hereinafter, the conventional example is shown in FIG. Reference numeral 100 denotes a water tank main body. A screw 104 driven by a motor 103 and a screw 104 are provided on a side surface of a tableware accommodating chamber 102 for accommodating immersion water 101 together with tableware (not shown) in the water tank main body 100.
And a jet outlet 105 located at the upper part of the.

In such a tableware immersion tank, the table 103 is driven by driving the screw 104 with the motor 103.

[0006]

In the tableware dipping tank shown in FIG. 6, if the dishes are arranged so that the flow of the dipping water 101 is not obstructed, the dirt separating action is higher than that of the conventional example in which the dipping water 101 is stationary. I understand. However, the tableware storage room 102
In order to stabilize the tableware inside, it is common to stack the tableware with the open side facing up or down, but if the tableware is stacked vertically, the flow of immersion water is in the vertical direction. The water flow is blocked by the dishes, which makes it difficult for immersion water to pass between the dishes. Therefore, there is a problem that it takes a long time to separate the dirt.

[0007]

The invention according to claim 1 is
An aquarium body is provided having a tableware storage chamber in which the immersion water is stored and the dishes are immersed in the immersion water in a stacked state, and a suction unit for sucking the immersion water in the tableware storage chamber and a jet for ejecting the sucked immersion water are provided. And a jet generator for circulating the immersion water in a substantially horizontal direction with a width corresponding to the depth of the tableware containing chamber.

According to a second aspect of the present invention, in the first aspect of the present invention, a bubble suction pipe having one end opened is provided at a position higher than the liquid level of the immersion water in the tableware accommodating chamber. The opening surface at the other end was arranged in the vicinity of the jet portion of the jet flow generator.

[0009]

According to the first aspect of the present invention, by driving the jet generator, the immersion water in the dish storage chamber is sucked by the suction portion of the jet generator, and the sucked immersion water is ejected from the jet generator ejecting portion. The dishes can be circulated in the dipping tank with a width corresponding to the depth of the tableware storage chamber, so that when the dishes are stacked vertically, the immersion water can be passed between the dishes stacked vertically. Therefore, it is possible to remarkably enhance the effect of separating dirt from a large number of dishes.

According to the second aspect of the present invention, when the immersion water is jetted from the jet portion of the jet generator, the pressure at one end of the bubble suction pipe located near the jet portion is reduced, so The outside air can be sucked in from the end, the outside air can be discharged along the flow of the immersion water as bubbles, and ultrasonic vibration can be generated along with the rupture of bubbles contained in the immersion water. Therefore, it becomes possible to further enhance the effect of separating dirt.

Next, as shown in FIGS. 1 and 2, an opening 36 is formed in the side surface of the dish housing chamber 32, and a flange 38 of a jet casing 37 is watertightly fixed to the opening 36 from the outside. A motor 39 is attached to the jet casing 37. A rotary shaft 40 of the motor 39 is supported by a mechanical seal 41 provided at the center of the jet casing 37, and an impeller 42, which is a jet generator, is fixed to the tip of the rotary shaft 40. The impeller 42 is arranged at the center and sucks in the immersion water, and a spout 42b that ejects the immersion water sucked from the suction part 42a from the outer peripheral portion.
And (see FIG. 3). In addition, a partition wall 44 having a suction hole 43 at the center and a suction strainer 46 having a large number of small holes 45 and facing the front surface of the partition wall 44 are provided on the front surface of the impeller 42 so as to be connected to each other. As shown in FIG. 1, one side of the partition wall 44 is rotatably held by a hinge 47, and the other side of the partition wall 44 is fixed by a screw 49 to a column 48 standing on the jet casing 37.

As shown in FIG. 1, the jet casing 3
7 is formed with an inclined surface 50 that gradually inclines toward one side of the tableware accommodating chamber 32 as it goes inward of the tableware accommodating chamber 32, and the inclined surface 50 and one side of the partition wall 44 are formed. A slender jet blowing passage 52 is formed in the depth direction of the tableware accommodating chamber 32 between the bent bent piece 51. In this embodiment, the jet casing 37 has a height of 150 mm, a width of 200 mm, and a depth dimension of 50 mm.
The impeller 42 is accommodated in this in a small size.

Further, as shown in FIG.
A plurality of bubble suction pipes 53 protruding from the outside to the inside are welded to the side surface of 2. Each of the bubble suction tubes 53 has a flexible tube 54 at the rear portion, the tip of the metal portion is arranged along the side edge on the outlet side of the jet flow passage 52, and the end of the tube 54 is at the tableware accommodating chamber 32. It is held so that the open end is located at a position higher than the level of the immersion water stored in. Further, a permanent magnet 55 is fixed to one side of the partition wall 44, and a magnetic sensitive switch 56 facing the permanent magnet 55 is fixed to the outer wall of the jet casing 37. The magnetic sensitive switch 56 is connected to a power supply circuit (not shown) that drives the motor 39.

In such a structure, the tableware dipping tank 30
The tableware accommodating chamber 32 is filled with the immersion water, and a large number of the dishes 29 are immersed in the immersion water and the motor 39 is driven to rotate the impeller 42. As a result, the immersion water in the tableware accommodating chamber 32 is sucked from the center of the impeller 42 through the suction hole 43 of the partition wall 44, the sucked immersion water is guided in the outer peripheral direction of the impeller 42, and the tableware is accommodated from the jet flow passage 52. It is blown out to one side of the chamber 32 and a circulating flow is formed in the immersion water. When the state of the circulation is viewed from above as shown in FIG. 1, the immersion water blown out from the jet blowing passage 52 once goes to one side of the tableware accommodating chamber 32 as shown by an arrow A, but the flow outside thereof. Since the direction is changed by the inner surface of the tableware accommodating room 32, it is directed to the other side of the tableware accommodating room 32 as shown by an arrow B, and further, as shown by an arrow C by multiplying the suction force by the central portion of the impeller 42. Partition wall 4
Head towards the suction hole 43 of No. 4. Further, when the flow of the immersion water is viewed from the side as shown in FIG. 2, it flows in a substantially horizontal direction with a width along the depth of the tableware accommodating chamber 32, as shown by an arrow D. This is because the jet flow passage 52 is vertically elongated. Accordingly, when the dishes 29 are stacked in the vertical direction, the immersion water can be passed between the dishes 29 that are vertically stacked, and therefore, the dirt separating action can be significantly enhanced. This is the effect corresponding to the invention of claim 1. By mixing a small amount of neutral detergent into the immersion water used in the tableware dipping tank 30, the effect of separating dirt from the tableware 29 can be further promoted.

According to the tableware dipping tank 30 of the present invention,
Since the immersion water can be circulated without the need for a pipe, downsizing and cost reduction can be achieved.

Further, the small hole 4 of the suction strainer 46.
There are cases where toothpicks, fibrous foods, etc. that have passed through 5 adhere to the periphery of the impeller 42. In this case, by loosening the screw 49 and rotating the partition wall 44 around the hinge 47, the impeller is rotated. The periphery of 42 can be widely opened.
As a result, the inside can be easily cleaned. In this case, when the partition wall 44 is opened, the permanent magnet 55 is separated from the magnetic sensitive switch 56, so that the magnetic sensitive switch 56 is maintained in the off state. As a result, the motor 39
It is possible to avoid the danger of automatically driving the power supply circuit for driving the motor and driving the motor with the impeller 42 exposed.

Further, in the tableware dipping tank 30, the suction strainer 46 covering the front surface of the impeller 42 has an opening 3.
6 does not protrude from the opening surface of 6, so that it is possible to prevent the tableware 29 from being damaged by the interference between the tableware 29 and the side edge of the suction strainer 46 when the tableware 29 is taken in and out.

Further, when the immersion water is jetted from the jet jet passage 52, the pressure at one end of the bubble suction pipe 53 located in the vicinity of the jet jet passage 52 decreases.
The outside air is sucked from the open end of the tube 54 of the bubble suction pipe 53, and the outside air is discharged as bubbles along the flow of the submerged water that is vigorously ejected from the jet blowout passage 52. These bubbles burst in the immersion water, and ultrasonic vibrations are generated accordingly, so that it is possible to further enhance the effect of separating dirt. This is effective in the invention of claim 2.

Next, referring to FIG. 5, a cleaning operation by the dishwasher 1 will be described. The cleaning water in the cleaning water tank 8 is preheated to about 65 ° C. by the heater 12, and the rinsing hot water in the rinsing tank 9 is preheated by a heater or a gas burner (not shown). In this case, in order to enhance the sterilizing effect and the drying effect of the tableware 29, it is desirable to control the temperature of the rinse water to about 85 ° C. As described above, the tableware 29 treated in the tableware dipping tank 30 is stored in the rack 28 placed on the soil table 2, the washing room hood 6 is raised, and the rack 28 on the soiled table 2 is tableware. Slide it into the washing chamber 5 of the washing machine 1 and lower the washing chamber hood 6. And
The washing pump 14 is driven for 50 to 90 seconds. As a result, the cleaning water in the cleaning water tank 8 is transferred to the lower cleaning nozzle 18
And, the dishes 29 are jetted from the upper washing nozzle 21 and washed. Then, by driving the rinse pump 15 for about 15 seconds, the rinse water in the rinse tank 9 is ejected from the lower rinse nozzle 24 and the upper rinse nozzle 27,
The dishes 29 are rinsed. The dishes 29 washed in this way are sent out onto the clean table 3 together with the rack 28 in preparation for the work of storing them in the cupboard.

In this embodiment, it is confirmed that the stains on the dishes 29 can be separated in about 1 minute when the output of the motor 39 of the dish dipping tank 30 is set to 200 W and the width of the jet blowing passage 52 is set to about 15 mm. It was This is about one-fifth as compared with the conventional tableware dipping tank in which the dirt of the tableware 29 is separated while the immersion water is kept stationary. As a result, the difference in processing capacity between the dish dipping tank 30 and the dish washing machine 1 becomes small, so that the dish dipping tank 30 separates dirt on the dishes 29 and the dish washing machine 1 cleans the dishes 29. It is possible to improve the efficiency of a series of work performed continuously with a cycle of.

Moreover, since the dirt separating action of the dish dipping tank 30 is very good, the dirt adhering to the dishes 29 is not brought into the dish washing machine 1, so that the washing water of the dish washing machine 1 becomes hard to be soiled. . As a result, it is possible to wash glass tableware and the like, which are required to have high transparency after washing, together with other pottery tableware without frequently changing the wash water. As a result, in comparison with the conventional example in which the tableware 29 is cleaned while the immersion water is stationary, the amount of wasted water and the amount of detergent consumed in the subsequent tableware washing are half the conventional amount.
The result was reduced to.

In the above embodiment, the tableware dipping tank 3 is used.
Although 0 has been described as an apparatus used in combination with the dishwasher 1, the dish dipping tank 30 may be configured as an independent apparatus. In this case, the dishes 29 may be washed after the treatment in the dish immersion tank 30 by using the dish washer 1 or manually. Even when washing manually, the dishes 29 can be cleanly separated from the stains in the dish dipping tank 30 according to the present invention, so that the subsequent washing work can be performed easily and cleanly, and stains on the washing water are small. can do.
