JP5033185B2 - Water supply device for pre-washing dishes - Google Patents

Description

  The present invention relates to a water supply device for pre-washing dishes for pre-washing dishes as pre-treatment when washing dishes in a commercial kitchen.

  Conventionally, a commercial tableware washing apparatus used in a commercial kitchen is known from, for example, Japanese Patent Publication (JP 2001-238842 A). This dishwashing apparatus includes a dishwashing section for prewashing dirty dishes, and a dish book washing section for washing dishes prewashed in the prewashing section. The pre-washing section includes a table for placing dirty dishes, a pre-washing sink for pre-cleaning dirty dishes, and a water supply device for supplying water (or hot water) to the pre-washing sink from above. Yes. The above-mentioned conventional water supply device is provided with a manual on-off valve that manually performs water supply and water supply stop, and when pre-washing dirty dishes, the operator manually operates the manual on-off valve to supply water from the water supply port. With the pre-washing sink filled with water, the pre-washing sink is filled with water. , Pre-washing to remove residues such as oil, sauce, egg yolk, etc. attached to dishes that are soiled by hand washing.

  By the way, in the pre-washing work of tableware in commercial kitchens such as hotels, inns, restaurants, etc., three types of dirty tableware used for Chinese, Western and Japanese dishes are generated. Here, among the above three types of dirty dishes, the dishes used for Chinese dishes and the dishes used for Western dishes are attached with oil and sauce, so it takes time to remove the residue in pre-washing. On the other hand, the dishes used for Japanese dishes are easier to remove than the dishes used for Chinese and Western dishes.

  However, in general, when pre-washing dishes, water supply is placed above the pre-wash sink regardless of whether the dishes to be pre-washed are used in the above Chinese dishes, Western dishes, or Japanese dishes. The present situation is that the tableware is pre-washed by hand washing while pouring water or hot water (hereinafter simply referred to as water) from the mouth.

  Therefore, such a conventional example has the following problems.

  a. Since the manual wash valve is manually operated to fill the pre-wash sink, it is necessary to visually check that the pre-wash sink is full and close the manual open / close valve. Rather than noticing that the pre-washing sink is full, it overflows and wastes water.

  b. When pre-washing dishes, pre-wash the dishes with water flowing down from the water supply port. Even if there is time between the completion of the pre-washing of one tableware and the start of the pre-washing of the next table during the washing operation, the water will continue to flow down from the water supply port all the time, and the water is wasted. End up.

  c. When pre-washing dishes, regardless of whether the dishes to be pre-washed were used for Chinese, Western or Japanese cuisine, or whether they were dirty, water was poured from the water supply port located above the pre-washing sink. Therefore, effective pre-washing according to the state of dirt is not possible, and there is less adhesion of oil, sauce, etc., especially compared to dishes used for Chinese and Western dishes, such as dishes used for Japanese dishes. Even when the residue is relatively easy to remove, water is used more than necessary for pre-washing.

  d. Since the worker is working without grasping his / her own water usage state, there is no motivation for saving water and saving energy, and work efficiency and energy efficiency are poor.

  e. The manager of the commercial kitchen cannot confirm the amount of water used per fixed time per day in the pre-washing work, and therefore cannot manage whether or not the amount of water used is appropriate. In addition, the amount of water used increases.

  f. Since the operator operates the water supply device by manual operation, the burden on the worker is large, and the number of times of contact with the water supply device increases, which is unsanitary.

  As a result of the above, conventionally, the amount of water used is large, and since it is a cleaning operation, the usage ratio of hot water is high, the consumption of hot water heating fuel is increased, and the amount of greenhouse gas emissions In addition, there is a problem that the cost for pre-washing dishes becomes high, the operation of the water supply device by the operator is troublesome, and there is a problem that it is not hygienic.

  The present invention has been invented in view of the above-mentioned problems, and the object of the present invention is to select a water supply mode corresponding to the purpose of supplying water in the pre-washing operation of tableware, and thereby to a pre-wash sink. It is possible to supply water for proper pre-washing corresponding to the dirty state of the tableware while preventing unnecessary dripping of water, and to save water and save energy. You can make yourself aware of the state of water use, and the water-saving effect of introducing a water supply device for pre-washing dishes is the same as the amount of water used before the pre-washing water supply device is introduced, and for pre-washing dishes. It can be recognized at a glance by comparing with the target value of water use when water supply equipment is introduced, and it gives strong motivation for water saving and energy saving whether current water usage is appropriate or not In addition, the manager of the commercial kitchen knows whether or not the amount of water used at regular intervals per day in the pre-washing operation of the tableware is appropriate or how much water is being saved. It is an object of the present invention to provide a water supply device for pre-washing dishes that can appropriately manage the amount of water used and can reduce the cost of pre-washing dishes.

  A water supply device for pre-washing dishes according to the present invention includes a water supply port for supplying water to the pre-washing sink from above in order to pre-wash dirty dishes, and a solenoid valve for supplying and stopping water to the water supply port, And a detection sensor that detects the presence of an object to be detected below the water supply port. In the water supply mode for the dishwasher water supply device, when the detection sensor detects the presence of an object to be detected below the water supply port, the solenoid valve is automatically opened to supply water from the water supply port, and the detection sensor supplies water. Sensor automatic feed / stop mode that automatically closes the solenoid valve to stop water supply when the presence of an object to be detected is not detected below the mouth, and starts water supply from the water inlet by opening the solenoid valve for a predetermined time When the water has passed or the water supply from the water supply port reaches a predetermined amount, the automatic water filling mode to the pre-washing sink that automatically closes the solenoid valve and stops water supply and the opening and closing of the solenoid valve are intermittently alternated The water supply mode has three water supply modes of intermittent water supply mode in which water is supplied intermittently from the water supply port. Mode setting means for selecting and setting any one of the three water supply modes and a display screen for displaying the amount of water used for supplying water from the water supply port are provided. The display screen includes a pre-installation display that displays an actual measurement value of a change in the amount of water used every predetermined time for pre-washing of the tableware before the installation of the above-mentioned tabletop pre-watering device, and the tableware Installed the target value display that displays the target value of the change in the amount of water used for a certain period of time in the day for pre-washing dishes by installing the pre-wash water supply device, and the above-mentioned dish pre-wash water supply device A current usage amount display that displays an actual measurement value of a change in the usage amount of the water supply for a certain period of time for pre-washing of the tableware in a state that has been performed is displayed.

  In this way, three water supply modes are provided, and when filling the pre-sink sink, the automatic water filling mode can be set so that the water can be accurately refilled. For pre-washing, set the sensor automatic supply / stop mode to place dirty dishes below the water supply port and supply water continuously throughout the pre-washing to effectively clean the dishes. If the pre-washing operation is temporarily interrupted, or if there is time before the next tableware is washed, the sensor will not detect the object (tableware) and the water supply will be automatically stopped. In the case of dishes used in Japanese cuisine or dishes with a relatively low level of dirt, water that has been filled in the pre-wash sink can be set by setting the intermittent water supply mode. Remove dirt and supply water intermittently It is as such that the rinsing with water, effectively can before washing with a small water supply amount, thereby effectively saving, energy can be saved.

  In addition, the display screen displays a pre-installation display that displays an actual measurement value of a change in the amount of water used for a certain period of time during the day for pre-washing the tableware before installing the pre-washing water supply device. Installed a target value display that displays the target value of the change in the amount of water used for a certain period of time in the day for pre-washing dishes by installing a pre-wash water supply device, and a pre-wash water supply device In the pre-washing sink in the state, the current usage display that displays the actual value of the change in the amount of water used for a certain period of time for pre-washing the tableware is displayed. By comparing with the amount display, the difference between the amount used before installing the tableware pre-washing water supply device of the present invention and the current amount used can be seen at a glance, and the tableware pre-washing water supply device of the present invention was installed. Specific water savings By comparing the target value display with the current usage display, it can be determined whether or not the current usage has reached the target usage indicated in the target value display. It is possible to let the worker know whether or not the water usage is appropriate, to give the worker a strong motivation for water saving, and for the administrator, It is possible to know whether or not the amount of water used at regular intervals in the day of pre-washing work is appropriate, or how much water is being saved, and appropriately manage the amount of water used. The cost of pre-washing dishes can be reduced.

  In addition, the pre-installation display showing the change in the amount of water supply used every fixed time in the day, the target value display, and the current usage display, one of the vertical and horizontal axes is used, and the other is time. It is preferably configured to be displayed as a bar graph so that the pre-installation display, the target value display, and the current usage display are overlapped and displayed at regular time intervals.

  In this way, the change in the amount of water used for a certain period of time per day in the pre-installation display, the target value display, and the current use display is displayed as an overlap of the bar graphs. Differences in usage display, difference between pre-installation display and target value display, difference between target value display and current usage display can be seen at a glance, and how much water is saved It is easy to understand whether you are doing.

  In addition, the operation panel includes a display screen, an operation unit for a sensor automatic supply / stop mode that constitutes a mode setting means, an operation unit for an automatic water filling mode, and an operation unit for an intermittent water supply mode. It is preferable to set the water supply mode by selectively operating the operation unit for the water supply / stop mode, the operation unit for the automatic water filling mode, and the operation unit for the intermittent water supply mode.

  Thus, by operating the operation part for the automatic water filling mode, it is possible to perform water filling to the sink for pre-washing, and by operating the operation part for the sensor automatic supply / stop mode, The water supply mode can be used to pre-wash dishes used in Western cuisine and dishes that are very dirty, and the water supply mode can be used to pre-wash dishes used in Japanese cuisine and dishes that are relatively dirty. Moreover, since the operation part of each mode is different, it can set to the target water supply mode, without operating incorrectly.

  Moreover, it is preferable to provide an operation unit for initial setting for performing initial setting of the water supply amount in the automatic water filling mode on the operation panel.

  The capacity of the pre-washing sink is different for each commercial kitchen, but the initial setting operation unit is operated corresponding to the pre-washing sink provided in the commercial kitchen where the dishwashing water supply device of the present invention is installed. Therefore, the initial setting of the water supply amount in the automatic water filling mode (that is, the setting that the pre-washing sink becomes full) can be performed, and in actual use, the automatic water filling mode is set to the automatic water filling mode. Do not overflow unnecessarily.

  In addition, the initial setting by the initial setting operation unit in the automatic water filling mode is the maximum water supply amount, and a water filling amount selection switch for selecting the maximum water supply amount and a smaller water supply amount is provided in the automatic water filling mode operation. It is preferable.

  When pre-washing dishes that have been set to intermittent water supply mode and used in Japanese cuisine, or dishes with relatively little dirt, operate the opening time setting operation section and the closing time setting operation section to turn the solenoid valve once. The opening time and closing time for each can be freely set, and optimal water supply in the intermittent water supply mode can be performed for each kitchen.

  Moreover, it is preferable that each downstream end of the water supply pipe line provided with the electromagnetic valve and the hot water supply pipe line provided with the electromagnetic valve is connected to the hot water mixing device, and the downstream side of the hot water mixing device is connected to the water supply port. .

  This makes it easy to pre-clean dirty dishes with hot water in order to improve the water-saving effect with the above three water supply modes. The amount of hot water used can be reduced, and the energy cost can be reduced.

  Moreover, it is preferable to provide the hot water mixing device with a hot water temperature adjusting operation unit for manually adjusting the mixing ratio of the water supplied from the water supply pipe and the hot water supplied from the hot water supply pipe.

  With such a configuration, the hot water temperature adjusting operation unit is manually operated to supply hot water at the optimum hot water temperature in each of the three hot water supply modes, so that the dishes can be pre-washed effectively.

  Moreover, it is preferable to provide the hot water mixing apparatus with the water supply amount adjustment operation part for adjusting the water supply amount manually.

  By adopting such a configuration, when performing the pre-washing of dirty dishes while providing the above three water supply modes and improving the water-saving effect, the amount of water supply can be further adjusted according to the dirty state of the dishes. , You can pre-wash dishes more effectively.

  By setting the water supply device 6 for pre-washing the tableware displayed as the target value display 32, the target value of the change in the amount of water used per predetermined time for pre-washing the tableware 2 is set as described above. It is determined on the basis of the actual measured value of the change in the amount of water used for a certain period of time for pre-washing the tableware 2 before the tableware pre-washing water supply device 6 is installed.

  In other words, in a commercial kitchen, as a result of experimentally determining the difference in the amount of water supply between the case where the pre-washing water supply device 6 of the present invention is installed and the case where it is not installed, the pre-washing of the present invention When the water supply device 6 is installed, the amount used is approximately 58% compared to when the water supply device 6 is not installed. Therefore, in this embodiment, the front of the tableware 2 before the water supply device 6 for pre-washing the tableware is installed. 58% of the measured value of the change in the amount of water used for a certain period of time in the day for washing is a target value, and based on this, a graph creation process is performed by the display processing unit 9f, as shown in FIG. A target value display 32 for each predetermined time (for example, one hour) is displayed on one common bar graph display unit 34.

  The target display 32 is displayed so as to be superimposed on the pre-installation display 31 displayed every fixed time (for example, 1 hour) on one common bar graph display unit 34. In the embodiment, the target display 32 is displayed for a fixed time (for example, 1 hour). ) Is displayed as a thick line at 58% of the pre-installation display 31 every time, and the difference between the tip of the pre-installation display 31 and the thick-line target display 32 is a water-saving target for each fixed time (for example, 1 hour) of the day. Amount. Thereby, for example, what is the target amount of water saving for one hour from 8:00 am to 9:00 am in the commercial kitchen where the water supply device 6 for washing dishes is installed, or 1 from 6 pm to 7 pm It is possible to grasp at a glance how much water saving target amount of time is.

  The actual value of the change in the amount of water used for a certain period of time for pre-washing of the tableware 2 in the state where the water supply device 6 for pre-washing the tableware displayed in the current usage amount display 33 is installed is the solenoid valve control. The calculation is performed based on the opening time of the electromagnetic valve 14 (14a, 14b) by the unit 9a and the instantaneous flow rate obtained by the flow sensor 17 when the electromagnetic valve 14 (14a, 14b) is opened, and every fixed time. An actual measurement value is obtained, and a graph creation process is performed by the display processing unit 9f, and a current usage amount display 33 for each predetermined time (for example, one hour) is displayed on one common bar graph display unit 34 as shown in FIG.

  The current usage amount display 33 is displayed as a bar graph superimposed on the pre-installation display 31 and the target value display 32 displayed every fixed time (for example, one hour) on one common bar graph display unit 34. The difference between the front end of the pre-installation display 31 displayed every time (for example, 1 hour) and the front end of the current usage amount display 33 is the amount of water saved every fixed time (for example, 1 hour) of the day. Thus, for example, what is the actual amount of water saved in one hour from 8 am to 9 am in the commercial kitchen where the water supply device 6 for washing dishes is installed, or from 6 pm to 7 pm You can see at a glance how much water is actually saved per hour.

  Further, by comparing the target value display 32 displayed every fixed time (for example, one hour) with the tip of the current usage amount display 33, the usage amount of the currently used water supply is compared with the target usage amount. You can see at a glance how much or how little.

  Next, the pre-washing operation | work of the tableware 2 in the commercial kitchen using the water supply apparatus 6 for the tableware pre-washing of this invention of the above structures is demonstrated.

  When the pre-washing water supply device 6 of the present invention is installed, the initial setting of the amount of water filled in the pre-washing sink 7 of the commercial kitchen where the initial setting operation unit 22 is operated to install the pre-washing water supply device 6 is provided. I do. In this case, the initially set amount of water filled is the amount of water in which the pre-washing sink 7 of the commercial kitchen is full, and this amount of water is for business use in which the dishwashing water supply device 6 of the present invention is installed. Different for each kitchen pre-washing sink 7.

  After the initial setting of the amount of water filled as described above, it is actually used. Hereinafter, the usage example will be described in detail.

  In the commercial kitchen of the embodiment shown in FIG. 4, in order to perform the pre-washing work of the tableware on that day, first, the operator turns on the power switch 30 of the operation panel 11, and further, for the automatic water filling mode. The operation unit 21b is operated to set the automatic water filling mode. FIG. 6 shows a control flow chart of the automatic water filling mode in the dishwashing water supply apparatus 6 of the present invention. According to the flow of this control flow chart, the opening / closing control of the solenoid valves 14 (14a, 14b) is performed. The pre-washing sink 7 is automatically filled with water.

  Here, in the embodiment shown in the attached drawings, since the operation unit 21b for the automatic water filling mode also serves as the water filling amount selection switch 28, the operation unit 21b for the automatic water filling mode is pushed once, twice or three times. Thus, it is set to either 1/3 or 2/3 of the initially set amount of water-filled water, or one of the initially set water-filled water amount (full water). As a result, when the solenoid valve 14 is automatically opened and water supply is started from the water supply port 12 and the water supply from the water supply port 12 reaches a predetermined amount (in the embodiment, the opening time of the electromagnetic valve 14 is a predetermined time), The valve 14 (14a, 14b) is closed to stop water supply, and the pre-washing sink 7 is filled with water (1/3 full water or 2/3 full water or full water is filled in the pre-washing sink 7). )

  In this manner, the pre-washing sink 7 is filled with water, and the tableware 2 is put on standby for pre-washing. Next, when the dirty tableware 2 is generated, the dirty tableware 2 is once placed on the table 5, and the dirty tableware 2 placed on the table 5 is pre-washed by hand washing. In this case, either the sensor automatic supply / stop mode operation unit 21a or the intermittent water supply mode operation unit 21c is operated according to the dirt state of the tableware 2, and the sensor automatic supply / stop mode or intermittent water supply mode is operated. Set to one of the water supply modes.

  If the tableware 2 is used for Chinese or Western dishes and the oil or sauce residue is difficult to wash away or is very dirty, the sensor automatic feed / stop mode operation unit 21a is operated to operate the sensor automatic feed / stop mode. Set to. FIG. 7 shows a control flow diagram in the sensor automatic supply / stop mode. According to the flow of this control flow diagram, the solenoid valve 14 (14a, 14b) is controlled to be opened and closed, and water is supplied from the water supply port 12. The water supply is stopped.

  That is, when the sensor automatic supply / stop mode is set, the detection sensor 15 detects the object to be detected (tableware or an operator's hand) in a certain area below the water supply port 12, so that the detection sensor 15 detects the tableware or the work. During the detection of a person's hand, the solenoid valve 14 (14a, 14b) is automatically opened for continuous water supply. Accordingly, the water supply is continued while the tableware 2 is hand-washed in a certain area below the water supply port 12, so that oil, the residue of the sauce, and terrible dirt can be reliably washed away by pre-washing.

  In pre-washing the above-mentioned dirty dishes 2, the whole or a part of the dishes 2 is soaked in water spread in the pre-washing sink 7, or the whole tableware 2 is stretched in the pre-washing sink 7. The residue is washed away with water supplied from the water supply port 12 while being put out on the surface of the water, and rinsed to perform pre-washing.

  During the operation in the sensor automatic supply / stop mode, when the tableware 2 has been rinsed and the detection sensor 15 no longer detects an object to be detected in a certain region below the water supply port 12, that is, a certain amount below the water supply port 12. When tableware or an operator's hand no longer exists in the area, the electromagnetic valve 14 (14a, 14b) is automatically closed, and water supply is temporarily stopped in the sensor automatic supply / stop mode. Thereafter, when the detection sensor 15 detects a tableware or an operator's hand, which is an object to be detected, in a certain area below the water inlet 12, the electromagnetic sensor 14 (14a, 14b) is automatically opened again to detect the detection sensor 15. However, while the tableware and the operator's hand are detected, the solenoid valve 14 (14a, 14b) is automatically opened to continuously supply water, and the tableware 2 having a high level of dirt is pre-washed.

  As described above, in the automatic sensor supply / stop mode, the water supply is continued during the hand washing operation of the tableware 2 in a certain area below the water supply port 12, so that oil and sauce residues and terrible dirt can be reliably ensured. In addition, since the water supply is stopped while the pre-washing of the tableware 2 is temporarily stopped in the sensor automatic supply / stop mode, the water supply is wasted in the sensor automatic supply / stop mode. Lost and can save water.

  To end the sensor automatic feed / stop mode, the sensor automatic feed / stop mode is turned off by operating the sensor automatic feed / stop mode operation unit 21a once again, and the mode ends.

  On the other hand, if the tableware 2 is used for Japanese cuisine or has relatively little dirt, the operation unit 21c for the intermittent water supply mode is operated to set the intermittent water supply mode. FIG. 8 shows a control flow chart in the intermittent water supply mode. According to the flow of this control flow chart, the solenoid valve 14 (14a, 14b) is controlled to be opened and closed, and water supply from the water supply port 12 is stopped. The

  That is, when the intermittent water supply mode is set, the electromagnetic valve 14 (14a, 14b) is alternately opened and closed alternately, and water is intermittently supplied from the water supply port 12. Therefore, the operator performs the hand-washing work of the tableware 2 while using both the hand-washing of the tableware 2 using intermittent water supply and the hand-washing of the tableware 2 soaked in the pre-sink 7 sink, Finally, rinse. In this case, since the tableware 2 is relatively dirty, even if the water supply from the water supply port 12 is intermittently supplied without continuously supplying water, it can be sufficiently pre-washed to save water. be able to.

  To end the intermittent water supply mode operation unit 21c, the intermittent water supply mode can be turned off by operating the intermittent water supply mode operation unit 21c once more.

  When washing the tableware 2 in the pre-washing sensor automatic feed / stop mode, the tableware 2 is washed in hand or in the intermittent water supply mode, and handwashing is performed using an appropriate detergent. The detergent to be used is used by the operator by manually attaching it to the tableware 2 or the cleaning sponge as needed, or automatically supplied from the detergent automatic supply device.

  Further, when the water stretched on the pre-washing sink 7 becomes dirty, if necessary, the drain valve (not shown) provided in the pre-washing sink 7 is opened to remove the dirty water in the pre-washing sink 7. Drain, close the drain valve after draining, operate the automatic water filling mode operation part 21b in the same manner as described above to fill the pre-washing sink 7, and then use the sensor automatic supply / stop mode or intermittent water supply mode Is selected and the tableware 2 is pre-washed by hand washing.

  As described above, the tableware that has been prewashed by selecting the sensor automatic supply / stop mode or the intermittent water supply mode is sent to the tableware cleaning unit 4 for main cleaning. In the tableware cleaning unit 4, automatic cleaning using a detergent and automatic rinsing are performed while the tableware 2 is transferred by an automatic transfer means such as a conveyor.

  By the way, in this invention, the sensor automatic feed / stop mode and the intermittent water supply mode are selected as described above, and the pre-washing operation of the tableware 2 is performed while water is supplied from the water supply port 12. It is characterized in that the water supply amount of today that is actually supplied from is displayed on the display screen 10 at regular intervals (in the embodiment, every hour).

  That is, when the power switch 30 is turned on, a pre-installation display 31 and a target value display 32 are displayed on the bar graph display unit 34 of the display screen 10.

  Next, since the water supply mode is selected as described above, the table 2 is pre-washed while supplying water from the water supply port 12 by controlling the opening and closing of the electromagnetic valves 14 (14a, 14b) according to the set water supply mode. However, the solenoid valve controller 9a at this time monitors the opening and closing of the solenoid valve 14 (14a, 14b), and the calculation is performed on the basis of the instantaneous flow rate when the solenoid valve 14 is opened, and the measured value is obtained every fixed time, A current usage amount display 33 is displayed every predetermined time (for example, one hour) so as to overlap the pre-installation display 31 and the target value display 32 displayed on the bar graph display unit 34. For the display at regular intervals, for example, every time the solenoid valve 14 is opened for 1 minute, a graph for an instantaneous flow rate (for example, 10 L / min) is displayed in the current time zone (for example, 14:00 to 15:00 in the example of FIG. 3). Stacked and displayed.

  The current usage amount display 33 displays the amount of water supply from the time when the power switch 30 is turned on to the present time every predetermined time (for example, 1 hour), so that the current usage amount display 33 is used for the daily pre-washing of the tableware. The operator can grasp at a glance how much the amount of water used is relative to the pre-installation display 31 and the target value display 32. The difference between the pre-installation display 31 and the current use display 33 It is possible to grasp the amount of water saved by installing the pre-washing water supply device 6 of the present invention.

  Further, when the current usage amount display 33 is below the target value display 32, the worker is strongly aware that the pre-washing operation is efficiently performed and the water-saving effect is increased, so that the worker is less than the target display 32. It is possible to give the worker a strong desire to perform efficient and efficient pre-cleaning work.

  Further, if the current usage amount display 33 exceeds the target value display 32, the worker is strongly aware that there is room for improvement in the manner of the pre-cleaning work currently being performed, and is selected according to the stains on the tableware 2. There is an effect of making the user aware of problems in hand-washing work, such as whether the setting of the water supply mode is appropriate, or whether the work procedure and time required for hand-washing the tableware 2 are appropriate.

  On the other hand, the manager of the commercial kitchen knows whether or not the amount of water used at regular intervals in the day of the pre-washing operation of the tableware 2 is appropriate or how much water is being saved. It is possible to manage the amount of water used appropriately.

  Thus, by providing the display screen 10 for displaying the pre-installation display 31, the target value display 32, and the current usage display 33, the water for pre-washing of the present invention is provided to both the operator and the administrator. In addition to appealing the water-saving effect due to the installation of the device 6, it is possible to give a strong motivation to water-saving and to improve the efficiency and cost reduction of the pre-washing work of dishes. Moreover, since water supply is automatically performed based on the selected water supply mode by selecting the water supply mode, the number of times that the operator touches the device to operate is reduced, which is sanitary.

  By the way, in the present invention, when water is supplied from the water supply port 12, the water supplied from the water supply line 16 and the hot water supplied from the hot water supply line 18 are mixed by the hot water mixing device 19 and supplied from the water supply port 12. It has come to be.

  The hot and cold mixing device 19 is provided with a hot water temperature adjusting operation unit 19a for manually adjusting the mixing ratio of water and hot water. By adjusting the hot water temperature adjusting operation unit 19a, water is supplied when pre-washing the dishes 2. The hot water temperature of the water (hot water) supplied from the mouth 12 can be adjusted.

  Moreover, in embodiment shown in FIG. 1, the water supply amount adjustment operation part 19b for adjusting the water supply amount of the mixed water mixed with the hot-water mixing apparatus 19 manually is provided.

  In the embodiment shown in FIG. 1, one operation lever provided in the hot water / water mixing device 19 serves as both the hot water temperature adjusting operation portion 19a and the water supply amount adjusting operation portion 19b. Adjusting the hot water temperature by changing the mixing ratio of water and hot water by moving, adjusting the amount of hot water by turning up and down with the operating lever in hand, that is, unit time from the water inlet 12 The amount of water supply per unit is adjusted. Of course, the hot water temperature adjustment operation unit 19a and the water supply amount adjustment operation unit 19b may be separate manual operation units.

  The adjustment of the water supply amount adjustment operation unit 19b is performed as follows, for example. For example, since it is necessary to fill the pre-washing sink 7 in a short time in the automatic water filling mode, it is necessary to fill the water in a short time. Therefore, the water supply amount adjustment unit 19b is operated to maximize the water supply amount per unit time (for example, 20 L / min). ) To supply water. Therefore, when the initial setting of the water supply amount in the automatic water filling mode is performed by setting the water supply time by operating the initial setting operation unit 22 as in the embodiment shown in the accompanying drawings. The water supply time until the pre-washing sink 7 is fully filled by continuously supplying water from the water supply port 12 in a state where the water supply amount adjusting operation unit 19b is operated to open to the maximum and the water supply amount per unit time is maximized. Will be set.

  Therefore, in the embodiment in which the water supply amount adjustment operation unit 19b is provided, when the operation unit 21b for the automatic water filling mode is operated to set the automatic water filling mode, the water supply amount adjustment operation unit 19b is operated to set the water supply amount. In this state, the pre-sink 7 is automatically filled with water. As a result, the pre-washing sink 7 can be filled with the desired amount of water in the shortest possible time.

  On the other hand, in the case of the sensor automatic supply / stop mode or the intermittent water supply mode, the water supply adjustment unit 19b is operated to adjust the degree of opening, and the water supply amount per unit time in the sensor automatic supply / stop mode or the intermittent water supply mode. Is arbitrarily adjusted (for example, about 10 L / min). Thereby, pre-washing can be performed with an optimal water supply amount per unit time for pre-washing the tableware 2, and workability can be improved while further saving water.
