The present invention relates to a rinsing structure and a rinsing method of a commercial dishwasher, and in particular, a rinsing water tank and a rinsing motor installed in the main body are installed in a plurality of first and second rinsing water tanks and first and second rinsing motors. The present invention relates to a rinsing structure and a rinsing method of a commercial dishwasher capable of performing a rinsing step of a dish in a double.

In general, restaurants such as restaurants that deal with a large number of people use a large number of commercial dishwashers to wash a large number of dishes. The commercial dishwasher is mostly used by connecting to one side of the sink washing sink that also serves as a basin tank, the rack containing the dishes in the center of the washing room, the lower part of the washing machine is installed, the washing room at the top of the washing room The covering cover is installed on the lift type.

That is, FIG. 1 is a perspective view illustrating a conventional general commercial dish washer, and FIG. 2 is a view schematically illustrating a conventional internal dish washer.

The dishwasher shown here is a pair of upper and lower cleaning nozzles 30a and 30b and upper and lower rinsing nozzles on the bottom and center of the upper and lower surfaces of the washing chamber 11, which are mostly opened by the upper lift cover 20. 50a and 50b are rotatably installed, respectively, and the upper and lower washing nozzles 30a and 30b spray the washing water toward the dishes in the rack placed in the center of the washing chamber 11 to perform the washing step. The lower rinse nozzles 50a and 50b are configured to spray the rinsing water toward the washed dishes to perform a rinsing step.

In addition, a washing water tank 40 and a rinsing water tank 60 are installed inside the lower body 10 of the washing chamber 11, and the upper and lower washing nozzles 30a are pumped by washing water in the washing water tank 40. Operation program of the rinsing motor 61 and the dishwasher to pump the rinsing water of the washing motor 41 and the rinsing water tank 60 to the upper and lower rinsing nozzles 50a and 50b. A circuit board (not shown in the drawing) and the like of the control unit for controlling the controller is installed.

In addition, hot water supplied through the water supply line 71 after being preheated to about 40 ° C. in a hot water booster or an instant water heater (not shown in the drawing) is partially provided by a distributor 70 in which each flow path is controlled to be opened and closed by a solenoid valve. Is introduced into the wash water tank 40, a part is introduced into the rinsing water tank 60, the hot water is lowered in the washing water tank 40 and the rinsing water tank 60 by the valve operated by the level sensor, respectively. The structure is automatically supplied, and a separate heater (not shown) is installed in the rinsing water tank 60 to heat the rinsing water to approximately 80 ℃ hot water.

In other words, when the rinsing step, the dishes washed with hot water as described above should be rinsed with the sterilization effect and can be quickly dried. Although not shown in the drawing, a predetermined amount of detergent is introduced into the washing water tank 40 by a separate detergent motor, and a predetermined amount of rinse is introduced into the rinsing water tank 60 by a separate rinse motor. It becomes the structure that becomes.

However, the following problems occur when the process of washing and rinsing dishes with a conventional dishwasher as described above occurs.

That is, when the lid 20 is closed and the dishwasher is driven while the rack containing the dishes is placed in the washing chamber 11, the washing motor 41 is put in a state in which a proper amount of detergent is put into the washing water tank 40 by a predetermined program. Is driven for a predetermined time, during which the washing water containing detergent in the washing water tank 40 is strongly sprayed into the dishware through the rotating upper and lower washing nozzles 30a and 30b and placed in the rack of the washing chamber 11. Wash the dishes.

However, when the washing step is performed as described above, some of the various wastes such as food residues on the dishes are splashed in all directions in the washing chamber 11 together with the washing water containing the detergent, so that the cover 20 forms the washing chamber 11. The ceiling and walls of the house are washed with a considerable amount of dirt and detergent.

After that, when the washing step is completed and the rinsing step is performed, the rinsing water of the rinsing water tank 60 pumped to the rinsing motor 61 is racked up and down through the upper and lower rinsing nozzles 50a and 50b. The rinsing process is strongly sprayed toward the dishes contained therein, and the rinsing process is splashed on the ceiling of the cover 20 constituting the washing chamber 11 and on the walls of all four sides. The ingredients are dropped onto the dishes in the lower rack.

Therefore, the conventional dishwasher tends to fall off the dirt and detergent components on the ceiling of the cover 20 and the walls of the four walls at the time of rinsing, and to reapply the dishware. There is a problem that harms the health because the very unsanitary and harmful to the human body remains in the dish as it is not different from that of the unhealthy state.

To this end, the upper nozzle 51 is installed upward on both ends of the upper rinse nozzle 50a so that the rinsing water is sprayed to the ceiling of the cover 20 and the upper end of the four-sided wall, but to the rinse water tank 60. The quantity of water once filled and heated to a high temperature of 80 ° C. is a limited amount of high temperature rinsing water used for washing the ceiling and all four sides of the wall until the end of the rinsing process. The amount must be small, which causes a problem that the rinsing effect is lowered.

In addition, as soon as the use of rinsing water is detected and the low water level is quickly detected, new water is immediately introduced, and a heater must be operated again to make it high temperature, thereby increasing power consumption and even heating to a high temperature. Rinsing with lukewarm rinse water may result in sterile drying effects.

In addition, to increase the area of the rinsing water tank in order to increase the rinsing time, a large amount of water must be heated at a high temperature at all times, thereby increasing power consumption, and as the rinsing water tank is enlarged, a large amount of rinsing is also required. As the consumption of the rinse increases, the maintenance cost of the dishwasher may be excessively increased.

The present invention was developed in view of the above-mentioned conventional problems, and an object of the present invention is to perform a rinsing process in a double process, but during the first rinsing, dirt and detergent components, which are buried on the ceiling and the walls of the cover, are placed on the tableware. It is to provide a rinsing structure and a rinsing method of a commercial dishwasher with good hygiene and sterilization drying effect by rinsing with a high temperature rinsing water at the time of the last second rinsing.

Another object of the present invention is to fill the existing rinsing water tank is heated to a high temperature while reducing the consumption of the rinsing water is put into the rinse as much as possible to prevent unnecessary consumption of power and rinse to reduce the maintenance cost of the dishwasher operation To provide a rinsing structure and a rinsing method of a commercial dishwasher.

Hereinafter, described in detail by the accompanying drawings, preferred embodiments of the present invention, which can effectively achieve the above object of the present invention by way of example.

3 is a view schematically showing the internal structure of the dishwasher of the present invention, a pair of upper and lower washing nozzles rotatably installed at the center of the bottom surface and the upper surface of the washing chamber 110 provided with a cover 120 ( 130a) 130b and upper and lower rinse nozzles 150a and 150b; The distributor 170 is installed in the lower body 100 of the washing chamber 110 and is installed in the water supply line 171 when the flow path is sensed by the water level sensor. The point provided with the wash water tank 140 is supplied through the water can be said to be the same as the conventional dishwasher configuration.

When the water level is sensed through the water level detector of the dishwasher, the water is supplied through the distributor 170 of the water supply line 171, and the rinsing water tank 160 in which the filled water is heated to a high temperature by a heater installed separately. ); A washing motor for supplying the washing water of the washing water tank 140 and the rinsing water of the rinsing water tank 160 to the upper / lower washing nozzles 130a and 130b and the upper and lower rinsing nozzles 150a and 150b, respectively. 141 and the rinsing motor 161; Also provided with a conventional dishwasher can be said to be.

The configuration feature of the present invention, the primary rinsing water tank separately installed so that hot water is stored through the other water supply line by adding a flow path that is controlled by the solenoid valve to the distributor 170 of the water supply line (171). 180; A primary rinsing motor 181 for pumping and supplying water in the primary rinsing water tank 180 to a rinsing nozzle to perform a primary rinsing process; The separate rinse to perform the first rinsing, the existing rinsing water tank 160 and the rinsing motor 161 is characterized in that configured to perform the second rinse to finish.

Here, since the rinsing water of the primary rinsing water tank 180 is to rinse the ceiling and the inner wall of the cover 120 first and to perform the rinsing of the washed dishes, the primary rinsing water tank 180. It is also possible to use only about 40 ℃ hot water stored in, that is, do not heat or rinse to a high temperature of about 80 ℃ using a separate heater, such as rinse water filled in the finishing rinse water tank 160 It can be said that it is preferable.

In addition, the rinsing nozzle is preferably used so that the rinse water is sprayed toward the ceiling of the cover 120 and the inner walls of the four sides by using a normal upper rinsing nozzle 150a having a known upward nozzle 151 at both ends. Do.

According to the present invention configured as described above, when the lid 120 is closed and the dishwasher is driven in the washing chamber 110, the dishwasher is driven according to a predetermined program. The first rinsing step → the second rinsing step of the tableware is performed in sequence as described in detail for each process as follows.

1st process (washing stage)

The washing water tank 140 is pumped into the washing water tank 140 with the washing motor 141 while the appropriate amount of detergent is put into the washing water tank 140 and supplied to the upper / lower washing nozzles 130a and 130b. When the upper and lower cleaning nozzles 130a and 130b are rotated, the spraying water is evenly sprayed from the top and the bottom toward the dishes contained in the rack, so that the washing steps of the dishes contained in the rack of the washing chamber 110 are performed. Part of the various dirt and washing water splashing from the tableware is buried in the ceiling and the inner wall of the cover 120 covering the washing chamber 110 as in the prior art.

2nd process (1st rinse step)

When the dish washing process is completed, the first rinsing motor 181 pumps hot water (rinsing water) filled in the first rinsing water tank 180 according to a program set in the control unit, and then sprays it through the rinsing nozzle. A tea rinse step is performed.

In this case, the first rinsing water supplied to the rinsing nozzle may be supplied to both the upper and lower rinsing nozzles 150a and 150b, but the first rinsing first rinses the ceiling of the cover 120 and the inner walls of the four sides. In addition, the upper rinse nozzle 150a for spraying the rinse water toward the ceiling of the cover 120 and the inner wall of the cover 120 and the upper and lower dishes because the upper nozzle 151 is installed at both ends to perform the rinse of the washed dishes. It is desirable to only spray through.

Then, the ceiling of the cover 120 and the inner walls of the four sides are clean, since the various dirt and detergent components that are stuck are washed down by the first rinsing water, and the dishes are in a rinse state.

Here, the first rinsing water is introduced through the water supply line 171 without heating or heating to a high temperature of about 80 ℃ using a separate heater, such as rinsing water filled in the existing rinsing water tank 160. It is preferable to use only hot water (about 40 ° C.) as it is, and this can reduce power consumption and rinse consumption during the first rinsing as much as possible.

3rd process (2nd rinse step)

When the first rinsing step is completed, the existing rinsing motor 161 is driven to spray rinsing water in the rinsing water tank 160 to the upper and lower rinsing nozzles 150a and 150b to perform a second rinsing process.

At this time, the secondary rinsing water in the rinsing water tank 160 supplied to the rinsing nozzle is also sprayed through the upper and lower rinsing nozzles 150a and 150b to rinse the dishes to the ceiling and the walls of the cover 120. It may splash and fall back to the tableware, but at this time, the dirt and detergent components on the ceiling and walls of the cover 120 are already removed during the first priming rinse process. There will be no.

In addition, if the second rinsing as described above, the rinsing may be ideal even if the rinsing process is not performed for a long time, so the rinsing time may be shortened. As a result, a rinse is added and heated to a high temperature of about 80 ° C. by the heater. Since the amount of secondary rinsing water (rinsing water in the existing rinsing water tank 160) can be reduced, maintenance costs for operating the dishwasher can be reduced according to power and rinse reduction.

As described above, the present invention allows the rinsing process after the washing process of the tableware to be carried out by the first rinse process and the second rinse process. There is an effect that can solve the problem of remaining on the table again.

When the first rinse is rinsed, the bulge is rinsed only with warm water that is not rinsed, and when the second rinse is rinsed with hot hot rinsed water in which the rinse is added, the hygienic and sterilization drying effect is good.

In addition, since the first heating is heated to a high temperature due to the primary rinse process, the second rinsing water containing the rinse can be reduced as much as possible, thereby reducing the maintenance cost according to the operation of the dishwasher.
