The inside of the door is a washing tank, and tableware baskets for placing tableware are installed in two stages, and the tableware basket can be pulled out to the front side by a slide rail movable by rollers. A conventional dishwasher can be used for 6 to 10 persons depending on the width of the main body. As a mainstream, the width of the main body is 45cm and it is generally used for 6 people. At home, more dishes may be used than usual depending on the content of the dishes and the number of guests. Also, when the number of people decreases, less dishes may be washed than usual.

[0003] For example, when the number of dishes increases, 1
After washing the dishes, the dishes must be taken out, the next tableware must be installed, and the second washing must be performed. It takes time and the first
It is not convenient to use as a dishwasher because it is necessary to care about the time when the second washing is completed. Further, when the number of dishes is reduced, the dishes are washed while leaving room for the dishwasher, so that extra electricity and water are used, which is uneconomical.

[0004] In addition, there has been a case in which a plurality of dishwashers are provided to enable washing according to the amount of dishes to be washed. The plurality of dishwashers are completely independently controlled, and no operation control has been performed in consideration of each other's operation state.

[0005] In the simultaneous operation, the current supplied to the heating heater at the same time suddenly increases, the power supply breaker is turned off, or the amount of water supplied sharply decreases due to the supply of water. It was inconvenient to use, and it took a long time to drain the water.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present invention does not cause a power interruption due to the operation of a power breaker, and reduces a sudden decrease in water supply, a long time of water supply, and a long time of drainage. It is an object of the present invention to provide a dishwasher operation control device which is easy and convenient to use.

SUMMARY OF THE INVENTION The present invention relates to an operation control device for a dishwasher having a plurality of dishwashers having a controller for operation control, wherein when a plurality of dishwashers are operated together, individual dishwashing is performed. The machine is provided with an arbitration circuit for instructing operation.

[0008] In this manner, when a plurality of dishwashers are operated simultaneously, the operation of each of the dishwashers is arbitrated, thereby suppressing the power supply breaker shut-off operation and the influence on water supply and drainage.
The time spent for operation can be greatly reduced compared to the case where one dishwasher is operated several times.

[0009] Since many dishes can be divided into a plurality of dishwashers and washed together, dishwashing is completed in a short time, and the dishwasher is easy to use.

Further, since the operation of each dishwasher is controlled by the instruction of the arbitration circuit, energization of the washing motor and overlapping of the heaters for heating are avoided, so that the power breaker does not shut off. Furthermore, since the overlap of the water supply was avoided, it was possible to suppress a decrease in the discharge pressure of the tap water faucet, an increase in the water supply noise or a prolongation of the water supply time. Furthermore, by avoiding overlapping drainage, it was possible to suppress the extension of drainage time and the increase in drainage noise.

Further, in the present invention, a controller for controlling a plurality of dishwashers and an arbitration circuit for arbitrating the plurality of controllers are provided as independent substrates independent of the controller. In addition, the controller and the arbitration circuit are provided with a function of transmitting mutual information by providing a communication function between the mounted microcomputers.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

First, a schematic structure of a dishwasher according to an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, two dishwashers are incorporated in a kitchen table of a kitchen so as to be arranged in upper and lower tiers. The washing tank 25 of the upper dishwasher and the washing tank 25 'of the lower dishwasher are put in and out like a drawer. Rails 27 provided in the cleaning tanks 25 and 25 'are configured to run on rollers 28 and run. The power switches 58 and 58 'are provided in the washing tank 25 of the upper dishwasher and the washing tank 25' of the lower dishwasher, respectively. Power switches 58, 58 'for easy operation
Is located on the front side.

As shown in FIGS. 2 and 3, the dishes 3 are arranged on a cupboard 29 provided in a washing tank 25. Cleaning tank 2
Tableware is arranged in the same manner in 5 ', though not shown.

A washing liquid (wash water) for washing the tableware 3 is supplied to the washing tank 25 through a water supply hose 60 from a water supply valve 59 (water supply valve) as a water supply device. A brushless motor 31 is provided directly below the bottom of the cleaning tank 25. The brushless motor 31 includes a permanent magnet on the rotor 30.
The rotating shaft of the brushless motor 31 supports a stirring pump blade 32 of the pump. This stirring pump blade 32
Is placed in the lower part of the cleaning tank 25.

The nozzle 33 has a plurality of spray holes 34 for spraying a cleaning liquid on its surface, and an opening 35 for suctioning the cleaning liquid is provided at the center. The nozzle 33 is rotatably mounted on the upper portion of the cleaning liquid guide 36 while maintaining an appropriate distance from the stirring pump blade 32 at the opening 35.

The cleaning liquid guide 36 extends at a constant interval from the bottom of the cleaning tank 25, has a ring-shaped cleaning liquid suction opening 37 on the outer periphery near the deepest part of the cleaning tank 25, and has a nozzle 33 at the center thereof. An opening 38 for discharging the cleaning liquid corresponding to the opening 35 is provided.

The cleaning liquid guide 36 is fixed to the cleaning tank 25 by screws 39.

A pump blade 40 of a drainage pump (drainage device) is mounted on the rotating shaft of the brushless motor 31 on the side opposite to the place where the stirring pump blade 32 is mounted, and a pump chamber 41 is provided around the drainage pump blade 40. The pump chamber 41 is communicated with the water reservoir 42 and the water guide 43 of the washing tank 25 at the shortest distance. The drainage pump blade 40 is configured to function as a drainage pump when the stirring pump blade 32 rotates in a direction opposite to the rotation direction that causes the stirring pump operation. For this reason, the brushless motor 31 is controlled to be able to rotate forward and backward.

When the drainage pump blade 40 functions as a drainage pump, the cleaning liquid in the cleaning tank 25 after cleaning is drained to the outside of the dishwasher main body through the drainage hose 44.

At the time of cleaning, the brushless motor 31 and the stirring pump blades 32 rotate to draw up the cleaning liquid from the vicinity of the deepest portion of the cleaning tank 25 and guide the cleaning liquid to the opening of the cleaning liquid guide 36 through the cleaning liquid guide 36. Further, the suctioned cleaning liquid is accelerated by the stirring pump blade 32 while being opened at the opening 3 of the nozzle 33.
From 5, it is guided to the injection hole 34 in a state where it is further accelerated along the casing 45 provided in the nozzle 33.

As described above, since the cleaning liquid is pressurized in the nozzle 33, it is jetted at high speed from the plural injection holes 34.
The nozzle 33 rotates in a certain direction due to a reaction when the cleaning liquid passes through the narrow casing 45 and a reaction when the cleaning liquid is ejected at high speed from the plurality of small ejection holes 34.

An arrangement portion for disposing the brushless motor 31 is provided at the central bottom of the washing tank 25. The arrangement portion is formed on the lower side by projecting the central bottom portion in a convex shape. The cleaning liquid guide 36 has a shape substantially conforming to the upper surface shape of the arrangement portion, and is arranged at a predetermined interval. A water passage is formed between the cleaning liquid guide 36 and the disposition portion.
By setting the cleaning liquid suction opening 37 (suction port of the water conduit) of the cleaning liquid guide 36 at the deepest part of the cleaning tank 25, the cleaning liquid guide 36 as the water conduit becomes the shortest.
Further, since the cleaning liquid is sucked from the deepest part of the cleaning tank 25, a stable cleaning liquid circulation path can be configured even if the height of the cleaning liquid surface is reduced. Since the headrace can be configured in the washing tank 25, there is no pipe loss in the headrace and a low-height circulation in the washing tank can be realized. The reduced height is advantageous in providing a kitchen-integrated dishwasher in which a plurality of washing tanks are vertically arranged.

A heater 46 for heating the cleaning liquid and heating the air is provided near the cleaning liquid guide 36. The air heating warms the air blown by the fan 53 when the dishes are dried.

The filter 48 for collecting residual vegetables is provided in the washing tank 2.
5 for collecting residual vegetables contained in the washing water when draining the washing water after washing.

The heater 46 has one end supported by an arm 50 of a heat-sensitive plate 49 provided at the bottom of the cleaning tank 25. The temperature of the heater 46 is obtained by obtaining information on the temperature from the heat-sensitive plate 49 and the sensor 51 thermally integrated with the heat-sensitive plate 49.
2 is controlled.

A packing 54 is provided all around the upper end of the cleaning tank 25, and the packing 5 is further mounted on a seal plate 55 above the cleaning tank 25.
4. When the cleaning tank 25 is withdrawn,
Also, prevent steam from leaking into the main unit during operation of the dishwasher.

When the cleaning tank 25 (25 ') is pulled out, the packing 54 on the inner side of the cleaning tank 25 scrapes water droplets adhered to the seal plate 55 into the cleaning tank 25, and does not drop into the main body. Further, in response to a signal from a detector (not shown) for detecting that the dishwasher has been stored, pressurized air generated by an air pump 56 attached to the washing tank 25 is added to the packing 54 through a pipe 57. With the configuration in which compressed air is sent, the storing operation is completed only by operating the power switch 58 after storing the dishwasher. It is possible to provide an easy-to-use dishwasher that can be stored by one action operation.

In the operating state of operation, the packing 54 is pressurized by the pressurized air against the seal plate 55 above the cleaning tank, so that the cleaning tank 25 cannot be pulled out. As described above, since the washing tank is strongly locked during use, there is no danger of accidentally pulling out the washing tank 25 during use and touching high-temperature water or the like during operation, so that the dishwasher is safe and easy to use.

FIG. 4 is a chart showing a standard washing-rinsing operation control content per dishwasher. First, in the washing step, the water supply valve 59 is opened, and the washing tank 25 is opened.
Supply water inside. After the water supply is completed, the water supply valve is closed, the heater 46 is turned on, the water temperature is heated to a predetermined temperature, the brushless motor 31 is rotated forward, and the stirring pump blade 32 is rotated to perform cleaning. After the cleaning is completed, the brushless motor 31 is rotated in the reverse direction, and drainage is performed by rotation of the drainage pump blade 40. Although the rinsing step has a different time limit, the control procedure of each load is the same as the above-described washing step (washing).

By the way, the dishwasher performs the above-described series of steps. If two upper and lower dishwashers are used at the same time, a situation occurs in which the steps overlap. For example, when the heaters are energized at the same time by two dishwashers, twice the current flows as in the operation of one dishwasher, and there is a possibility that the power breaker may be turned off depending on the power usage in the home. .

The present invention for solving this problem will be described in detail below.

FIG. 5 shows the controller 52 and the arbitration circuit 66.
1 is a schematic circuit diagram showing a connection circuit of FIG. When starting the operation, the controller 52 first transmits an operation request signal 67 (a) to the arbitration circuit 66. The arbitration circuit 66
The operation request signal and the operation state of the other dishwasher are determined, and if the output is not used by the other dishwasher, an operation permission signal is output to the request source controller.

On the other hand, in order to cope with the case where the same operation request signal is simultaneously input from the upper and lower dishwashers to the arbitration circuit 66, two dishwashers are given priorities in advance, and control is performed according to the priorities. There is a way. For example, if the upper dishwasher is given priority and the same operation request signal is received from two dishwashers at the same time, the operation permission signal is given to the upper dishwasher first, and the same operation request signal is simultaneously given. The operation control can be performed without confusion even when the vehicle enters. Thus, even when two dishwashers are operated at the same time, it is possible to prevent the power breaker from being shut off.

FIG. 6 shows an arbitration circuit 66 between two dishwashers.

Issue 67 (b). On the other hand, the arbitration circuit 66 issues an operation permission signal 68 (a) to the upper controller 52 (a), which is the priority machine, because the requests having the same contents are made at the same time.
The upper controller 52 (a) receives the operation permission and
9 (a) is output and water is supplied.

When the water level in the washing tank 25 reaches the set value, the output to the water supply valve 59 (a) is stopped, and the output release signal 67 (c) is transmitted to the arbitration circuit 66. The arbitration circuit 66 receives this signal and issues a permission to operate the water supply valve 59 (a) to the lower dishwasher controller 52 (b). Subsequently, the upper controller 52 (a) transmits an operation request signal 67 (a) for the heater 46 (a) and the brushless motor 31 (a) to the arbitration circuit 66. Since the lower dishwasher is supplying water and the heater 46 (a) and the brushless motor 31 (a) are energized at the same time, no inconvenience occurs, so the arbitration circuit 66 issues an operation permission signal 68 (a). When the water supply is completed, the lower controller issues an operation request signal 67 (b) to the arbitration circuit 66 for the heater 46 (b) and the brushless motor 31 (b). Motor 31
Since (a) is in operation, the operation at the upper stage is waited for, and then the operation permission 68 is given to the lower controller 52 (b).
Issue (b). The upper controller 52 (a) issues an operation request signal 67 (a) for the brushless motor, while the arbitration circuit 66 outputs an operation permission signal 68 (a). After draining is completed, the upper controller issues an output request signal and an operation request signal 67 (a) for the water supply valve 59 (a) to supply water in the rinsing step, and the arbitration circuit 66 outputs an operation permission signal 68 (a). After the water supply is completed, an output release signal and a heater and brushless motor operation request signal 67 (a) are output. At this time, the lower dishwasher is operating the heater 46 (b) and the brushless motor 31 (b). Therefore, after confirming the end, the arbitration circuit 66 issues an operation permission signal 68 (a) to the upper dishwasher. The lower dishwasher outputs an output request signal 67 (b) of the brushless motor 31 (b) for drainage, and the arbitration circuit 66
The drainage is performed in response to the output permission signal 68 (b). After the drainage is completed, a water supply output request is issued to perform the water supply work in the rinsing step, and the arbitration circuit 66 permits the request. After the water supply step is completed, an output request for the heater 46 (b) and the brushless motor 31 (b) is issued.
And the brushless motor 31 (a) are operating, the arbitration circuit 66 waits for the upper dishwasher to open the heater 46 (a) and the brushless motor 31 (a), and the operation permission signal 6
Issue 8 (b). Upper controller is brushless motor 3
1 (a) is output to the arbitration circuit 66, and the operation permission signal 68 (b) from the arbitration circuit 66 is obtained to operate the brushless motor 31 (b). All steps are completed.

After the output of the heater 46 (b) and the brushless motor 31 (b) is completed, the lower stage dishwasher reversely outputs the brushless motor 31 (b) for drainage, and the entire process ends.

Next, a description will be given of a dishwasher in which the operation permission of a plurality of dishwashers is time-divisionally divided and alternately operates.

FIG. 7 shows an arbitration circuit 66 between two dishwashers.
4 is a chart showing operation control contents in the case where is interposed.
Here, the upper-stage dishwasher is set as the priority machine, but the description will be made on the assumption that the two units are operated together in a time-sharing manner.

First, the controller 5 of the upper dishwasher
2 (a) and the controller 52 (b) of the lower dishwasher perform a water supply operation in the washing process, so that the operation request signal 67 (a) of the water supply valves 59 (a) and 59 (b) is simultaneously sent to the arbitration circuit. , 67
Issue (b).

On the other hand, the arbitration circuit 66 requests the upper controller 52 (a), which is the priority device, to permit the operation and the operation permission signal 68 having information on the permissible time of the operation, since the request of the same content is made simultaneously. Issue (a). Here, the operation permission time is set to a short time within a range in which no practical problem occurs for each control target.

The upper controller 52 (a) receives the operation permission signal and outputs water from the water supply valve 59 (a) to supply water during the permitted operation time. When the permitted operation time ends, the output to the water supply valve 59 (a) is stopped, and the output open signal 67 (c) is transmitted to the arbitration circuit 66.

The arbitration circuit 66 receives this signal and supplies the water supply valve 59 (a) to the lower dishwasher controller 52 (b).
Of the operation permission signal 68 (b). The upper dishwasher,
The lower dishwasher repeats the above series of operations until the water level in the washing tank 25 reaches a set value.

Subsequently, the controllers 52 (a) and 52 (b) of the upper and lower dishwashers perform washing in the washing process.
The operation request signals 67 (a) and 67 (67) of the heaters 46 (a) and 46 (b) and the brushless motors 31 (a) and 31 (b), respectively.
(B) is transmitted to the arbitration circuit 66.

The arbitration circuit 66 issues an operation permission signal 68 (a) to the upper-stage dishwasher, which is the priority machine.

The upper controller operates the heater 46 (a) and the brushless motor 31 (a) for the permitted operation time, and then outputs an output release signal 67 (c) to the arbitration circuit 66.

The arbitration circuit 66 receives the output release signal 67 (c) from the upper dishwasher and issues an operation permission 68 (b) to the lower dishwasher.

The lower controller operates the heater 46 (a) and the brushless motor 31 (a) for the permitted operation time, and then outputs an output release signal 67 (d) to the arbitration circuit 66.

The upper dishwasher and the lower dishwasher repeat the above series of operations until the washing is completed.

Subsequently, the controllers 52 (a) and 52 (b) of the upper and lower dishwashers perform an operation request signal 67 () of the brushless motors 31 (a) and 31 (b) in order to drain the washing process. a) and 67 (b) are transmitted to the arbitration circuit 66.

The arbitration circuit 66 issues an operation permission signal 68 (a) to the upper-stage dishwasher which is a priority machine.

The upper controller drains the water in the washing tank 25, so that the brushless motor 3
After the inversion operation of 1 (a), an output release signal 67 (c) is output to the arbitration circuit 66.

The arbitration circuit 66 receives the output release signal 67 (c) from the upper dishwasher, and issues an operation permission 68 (b) to the lower dishwasher.

The controller at the lower stage outputs the output open signal 67 (d) to the arbitration circuit 66 after the brushless motor 31 (a) is operated in reverse for the permitted operation time.

The upper dishwasher and the lower dishwasher
The above series of operations are repeated until drainage is completed.

The above is the contents of the washing step. Thereafter, the process proceeds to the rinsing process, but the content of the control is the same as that of the above-described washing process.

Next, a control method for simultaneously outputting operation permission to a plurality of dishwashers without time sharing will be described.

In the invention of the above-described embodiment, the dishwasher, which has received the operation permission from the arbitration circuit, operates exclusively the device to be controlled at 100% output within the time permitted for the operation. On the other hand, in the present embodiment, by performing "weighting" on the operation control, it is possible to eliminate inconveniences such as a power breaker shut-off operation while simultaneously operating the same control target device with a plurality of dishwashers. .

The simultaneous operation will be described in more detail with reference to the chart of FIG.

The operation of the two dishwashers is controlled by an arbitration circuit 66. The upper dishwasher located in the upper section selects a so-called `` careful course '' in which the heater temperature is high and the washing time is long for washing dishes that are heavily soiled, and the lower dishwasher located in the lower section uses dishwashers that are dirty to the standard level. In order to wash, the heater temperature and the washing time select a so-called "standard course" in which the two dishwashers are simultaneously operated.

First, the controller 52 of the upper dishwasher
a and the controller 52a of the lower dishwasher simultaneously supply the water supply valve 5 to the arbitration circuit 66 in order to supply water in the washing process.
The operation request signals 67a and 67b of 9a and 59b are issued.

On the other hand, the arbitration circuit 66 issues the operation permission signal 68a having the information of the operation permission and the upper limit of the output to the upper controller 52a, which is the priority device, because the request of the same content is made at the same time. . Subsequently, an operation permission signal 68b having information on the operation permission and the output upper limit of the operation is issued to the lower controller 52a. In addition, the output upper limit of the said operation | movement points out the limitation of the amount of tap water, the capacity range of electric current, etc. As for water supply, it refers to the restriction of the amount of water that does not cause water thinning or interruption in other taps of ordinary households. Regarding electricity, it refers to the limited range of the current capacity in which the power breaker does not shut off.

The upper controller 52a and the lower controller 52b receive the above operation signal, and each of them does not exceed the upper limit of the permitted output (50 to 5 in the case of water supply).
In step 0), the water supply valve 59a and the water supply valve 59b are operated so as to open and output water to supply water. In this case, the degree of opening of the water supply valve 59a and the water supply valve 59b is maintained at about half of that at the time of full opening.

When the water level in the washing tank reaches the set value,
The upper and lower two dishwashers are a water supply valve 59a and a water supply valve 59.
The output to b is stopped and operated. At the same time, an output release signal 67c and an output release signal 67d are transmitted to the arbitration circuit 66 to notify that the output has been stopped. Further, in order to perform the next operation of washing by heating, an output request signal of the heater 46 and the brushless motor 31 is issued. That is, the upper controller 52a and the lower controller 52b
Requests the output required to execute the set operation contents. Specifically, the temperature reached by the heater, the number of rotations of the motor, and the like can be considered.

In response to the above request, the arbitration circuit 66 outputs an operation permission signal of operation permission including operation weighting to each dishwasher. Thus, for example, assuming that the capacity of the power breaker in the kitchen is 100, the upper-stage dishwasher operating on the careful course is 7
0, 30 for the lower dishwasher operating as standard
Make a distribution such that The operation is permitted by weighting in consideration of such distribution. By doing so, even if the upper and lower dishwashers are operated at the same time, the total current capacity does not exceed the power breaker capacity, so that there is no problem that the power breaker is shut off.

[0070]

According to the present invention, there is no power interruption due to the operation of the power supply breaker, and a sharp decrease in water supply, a long time supply, a long time drainage, and the like are reduced, and an easy-to-use dishwasher is provided. An operation control device can be provided.
