Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a washing water swirl prevention device in a dishwasher for commercial use, in which a large number of dishes are continuously washed.

<Prior Art> Generally, as a commercial dishwasher used in a so-called revolving sushi restaurant or the like, a dish carrying-in means, a washing means, a drying means and a dish unloading means are sequentially arranged in a longitudinal direction on one belt conveyor. Known as the conveyor belt type dish washer located in the above, and the turntable type dish washing machine (Practical application No. 61-200147) presented earlier by the applicant of the present application, but recently, a turn table that can be made compact Dishwashers are the mainstream. In this case, the cleaning means is a combination of a rotary brush and a cleaning liquid jet nozzle, and after cleaning, it is simply transferred to the drying means which is the next step. For this reason, the water droplets of the washing water are often circulated to the position of the plate unloading means including the drying means.

<Problems to be solved by the invention> That is, it is often the case that water droplets of washing water adhere to the dish and the transfer means (turntable) and are circulated from the drying means to the dish unloading means. There is also a risk of water droplets remaining from the transfer means. This is especially noticeable in the turntable type dishwasher.

In view of the above situation, an object of the present invention is to provide a washing water swirl prevention device for a dishwasher that wipes water drops on the dish and the turntable surface passing through the washing means position and prevents the washing water from scattering at the washing step position. It is what

<Means for solving the problem> At a position where the turntable is divided into four equal parts, a plate set portion is arranged at the upper part and a plate receiving / dropping rod having a C-shaped cross section is arranged at the lower part. A tray carrying means, a rotating brush facing the inside of the housing, a cleaning means with a cleaning liquid, a drying means including a draining disk and rolling balls, a tray including a tray pusher arranged below the turntable and an upper non-return pawl. In the dish washing machine in which the carry-out means is arranged and the dishes to be stacked from the dish carry-in means are intermittently moved to one sheet, in the entire lower end width of each partition wall of the dish carry-in means, the washing means, the drying means, and the dish carry-out means, A wiping curtain made of polyethylene, rubber, etc., having a length such that its tip slides on the surface of the turntable, is stretched and fixed.

<Operation> Due to the above-mentioned configuration, the dish carried into the cleaning process position by the rotation of the turntable is brushed and cleaned by spraying the cleaning liquid and rotating the rotary brush. The splashed water at this time flies to the surrounding partition walls and the position where the turntable passes through, but since a wiping curtain is placed at the lower end of this partition wall, the flow into the adjacent plate loading process and drying process side does not occur. If there is no water drop around the turntable after cleaning and the wiper curtain slides on the plate and turntable surface, the water drops will be forcibly wiped off and will not be brought into the next process. There is no turning).

<Embodiment> The present invention will be described below with reference to the drawings of the embodiment.

Reference numeral 1 denotes a net frame type turntable which is installed in a hermetically sealed housing 2 and has four pan receiving frame holes 3 formed on the periphery thereof with intermittent rotation of 1/4 rotation, and each pan receiving frame hole 3 of the turntable 1 is , Housing 2
It is configured such that the set positions are set at the dish loading process position 2a, the washing process position 2b, the drying process position 2c, and the dish unloading process position 2d that partition the tray. Reference numeral 4 denotes a wiping curtain made of polyethylene, rubber or the like having a length that makes sliding contact with the upper surface 1a of the turntable 1 arranged below the lower ends of the partition walls 5a, 5b, 5c, 5d for partitioning the respective steps. The curtain 4 is stretched so as to be inclined toward the rotation direction of the turntable 1. 6 is plate loading means, 7 is cleaning means, 8
Is a drying means, and 9 is a plate carry-out means. A part of the plate carry-out means 9 and the plate carry-in means 6 is partly exposed from the housing 2, and the setting part 6a of the plate A to be stacked at the exposed position on the front side thereof. And unloading section 9a
Is provided, and it becomes the rotary dishwasher 10 as a whole.

Next, this operation will be explained. First, a large number of trays A set on the tray receiving / single-pointing dropping rod 11 having a C-shaped cross section, which is a pair of the tray loading means 6 for dropping one tray. The lowermost plate A is interlocked with the intermittent rotation of the turntable 1 through the transmission mechanism 12 as appropriate, and the receiving rod 11 is rotated and once received by the C groove portion 11a, and when the C groove portion 11a faces directly below. A falls,
This bottom portion Aa is set in the dish receiving frame hole 3 of the turntable 11. Next, the tray A is moved by the intermittent rotation of the turntable 11 through the wiping curtain 4 at the lower end of the partition wall 5a to the cleaning step position 2b.

At the cleaning step position 2b, cleaning is performed with the brushing of the rotary brush 13 in contact with the upper and lower surfaces and the cleaning liquid (generally, a mixed liquid of sterilizing liquid and hot water or only hot water) from the side injection nozzle 14. In this case, the splashed water droplets of the cleaning liquid are received on the surface of the cleaning tank portion 2 ', and the wiping curtain is applied to the lower end gaps of the partition walls 5a and 5b, which are the passage positions of the dish conveying portion 1b of the turntable 1.
Since 4 and 4 are laid, they exert a shielding effect on the adjacent tank portion, do not wet the plate loading process position 2a and the drying process position 2c, and further, the plate A surface attached at the cleaning process position 2b. Water droplets on the surface of the turntable 1
When it is rotated, it is drained and wiped by the wiping curtain 4. The wiped water droplets and the washout water (drainage) for cleaning are collected in the drainage tank portion 16 below and appropriately drained.

Next, the plate A that has advanced to the drying process position 2c is a high speed drying means 17
The bottom surface Aa rides on the water draining disk 18 facing the lower part of the tray receiving frame hole 3, and the ball bearing type rolling ball 19 projecting above the turntable 1 is set at the center position of the upper surface of the tray A. It In this case, since the supporting member of the rolling ball 19 is swingable by the leaf spring 20, the rolling ball 19 serves as a vibration buffer when the rolling ball 19 enters the dish A and rotates at high speed. In this state, if the draining disk 18 rotates at a high speed in association with the rotation of the separate high-speed motor 21, the dish A rotates at a high speed, water droplets are scattered by this centrifugal force, and the hot water is sprayed in the washing process. Combined with the warmth of the plate itself, the water will be forced to dry. The plate A which has undergone this drying step goes underneath the wiping curtain 4 of the partition wall 5c and advances to the plate unloading step position 2d. Here, the plate pusher 24 of the push-up plunger 23 of the plate unloading means 22 abuts and pushes up against the bottom portion Aa of the plate A, and pushes up the check claw 26 of the plate stocker portion 25 located outside the housing. As the rear dish pusher 24 descends, the dish A is received by the check claw 26 and stops. Hereinafter, the dishes A are sequentially stacked one by one from below. Even when moving to the dish unloading step, the water drops on the turntable 1 are completely wiped off because they pass through the wiping curtain 4.

<Effect of device> As described above, the cleaning water swirling prevention device in the dish washing machine of the present invention is the lower end of the partition wall that serves as a boundary between the steps of the turntable (dish loading process, cleaning process, drying process, dish unloading process). In addition, by adopting a configuration in which a wiping curtain having a length that makes sliding contact with the turntable surface is arranged, it is a matter of course that the spattered liquid does not directly reach the adjacent tank part during the cleaning process, and the turntable method is used. The number of water droplets that need to be routed (carried into the next process) can be completely wiped by the sliding contact of the wiping curtain, and there is no water in the final plate discharge process section (turntable). Including), and then it is a dry dish. Further, since the present invention has a simple structure in which a soft curtain is arranged, it is possible to disengage the plate set in the plate receiving frame hole from the plate receiving frame hole without hindering the rotation of the turntable itself. There is a practical effect such as no.
