Japanese Patent Laid-Open No. 10-272065 JP 2003-042831 A JP 2002-186524 A

  By the way, although what is disclosed in Patent Document 1 is connected to various heaters of gas type for grilling, sheathed heater heating type for iron plate, electromagnetic heating type for tempura, these are connected. The heating sources of the heaters used are used only individually. For this reason, even if the heaters are connected, the connection to the commercial power source is individually required, and the number of parallel wires in proportion to the number of heaters is necessary. For this reason, in order to handle and provide a variety of cooked foods with a large number of heaters, an inconvenient space is required for routing the wiring, and there is a risk of catching and it is uncomfortable. Also, if there is excessive power consumption due to the simultaneous use of multiple handling devices, an overcurrent will flow and the electric breaker will operate and a power failure may occur, but it is difficult to cope with such a situation in advance and it is easy to encounter a power failure .

  The one disclosed in Patent Document 3 is a cold insulation tank in which a first heat insulation region having a heating lamp such as an infrared lamp, a second heat insulation region having an electric heater, a peripheral wall and a bottom surface are insulated by a cutting material in a wagon body. The heating lamp and electric heater are individually provided with a grounded outlet for connection to a commercial power source. Therefore, even in this case, a plurality of heat insulation regions with reduced heating are provided in one wagon, but the number of parallel wires in proportion to the number of heat insulation regions is individually connected to the commercial power supply. There is a problem similar to that described in Patent Document 1.

  In addition, patent document 2 is disclosing only that the cooking thing is arranged in the Viking type per cooking corner. That is, there is no proposal about the presence or absence of a heat source or the like and a power feeding method, and it does not solve the problems of the conventional methods, for example, the methods described in Patent Documents 1 and 3.

  Therefore, the applicant can connect multiple handlers to the series to simplify the power supply wiring to those heat sources, and handle multiple types of foods with multiple handlers while keeping them in the middle of multiple people. It is proposed separately that it can be shared.

  However, while this inventor has further experimented and studied this proposal, in such a power supply system, in order to guarantee the power consumption required for each heat source, the heat sources are connected in parallel to the power source. However, depending on the number of handling devices connected and the types of handling devices connected to each other, it was found that overcurrent flows through the power supply circuit, causing failure, and causing an electrical breaker to cause a power failure. .

  The object of the present invention is to provide a method and apparatus for handling food by a plurality of handling devices that can guarantee that no overcurrent will occur even when a plurality of handling devices are connected to a series based on such new knowledge and used simultaneously. It is to provide.

  In order to achieve the above object, the method of handling the cooked food by the multiple handling device of the present invention is to connect the multiple handling devices to the series, energize each heat source, cook the cooked food by each heat source, While providing at least one of heat insulation and cold preservation, each heat source is turned on and off so that the total power consumption at that time is within the predetermined power consumption range, One feature is that the power consumption required for handling the cooked food is satisfied.

  In such a configuration, by connecting a plurality of handling devices in series and energizing those heat sources, the handling function of each handling device is activated to handle at least one of cooking, keeping warm, and keeping cold for the food. By simultaneously turning on and off each heat source so that the total power consumption at that time falls within the predetermined power consumption range, an overcurrent flows when the power consumption exceeds the predetermined range. This can be prevented.

  As a device for handling cooked food by a plurality of handling devices that achieve such a method, a plurality of handling devices having a heat source that works by energization and having at least one handling function of cooking, heat insulation, and cold keeping for the food, Connect each handling device to the series and supply power to those heat sources, and turn on and off each heat source so that the total power consumption at that time is within the specified power consumption range. And a control means for satisfying the total amount of power consumption required for handling the cooked food in the vessel.

Here, energization of each heat source is performed at an extraordinary timing that does not overlap,
By simply controlling the distribution of energization time, it is possible to avoid overcurrent from flowing due to excessive power consumption, and by responding to differences in power consumption required for individual heat sources by providing a difference in distribution time be able to.

  The handling method of the food by the multiple handling device of the present invention is also such that the plurality of handling devices are connected in series to energize each heat source, and at least one of cooking, keeping warm, and keeping cold with respect to the cooked product by each heat source. Depending on the energization amount of the parent unit including one of the multiple handling units as the parent unit and the other unit connected to the parent unit, Another feature is to control energization to the vessel.

  In such a configuration, one or more slave units are connected to a series with the parent unit among a plurality of handlers as a base point, and the heat source is energized to raise the handling function of the individual handlers. At the same time, at least one of cooking, heat insulation, and cold insulation is proceeded, but the total power consumption for starting up the heat sources of multiple connected devices is reflected in the energization amount of the parent device as the base point. Since the energization to the slave unit is controlled in accordance with the energization amount monitored, it is possible to avoid an excessive current from flowing due to excessive power consumption depending on the type and number of the slave units connected to the master unit.

  As a device for handling cooked food by a plurality of handling devices that achieve such a method, a plurality of handling devices having a heat source that works by energization and having at least one handling function of cooking, heat insulation, and cold keeping for the food, One handler is used as a master unit and this master unit is connected to one or more series as other handlers as slave units, and their heat sources are energized with the master unit as a base point, and each unit is subjected to predetermined handling. Another feature suffices to be provided with a power supply circuit and control means for controlling energization to the slave unit according to the energization amount including the slave unit in the master unit.

Here, the control is performed based on communication information between the parent device and the child device connected to the parent device.
The connection status of the slave unit to the master unit can be known in the master unit by communication from the connected slave unit, and the connection status of the slave unit to the master unit, that is, the type and number of slave units to be connected are undecided. Even when there is a slave unit, the connection and type of the slave unit can be monitored to immediately determine whether the connection is in a usage condition in which overcurrent flows beyond the specified power consumption range. The energization can be controlled so as not to exceed.

In this case, the energization control to the slave unit is such that when the energization amount in the master unit exceeds a predetermined range, the energization to all or all of the slave units is cut off.
Even if the connection of the slave units becomes excessive, it is possible to prompt the user to reconnect the slave units while using the master unit by cutting off the power to all the slave units, and to cut off the power supply to the excessively connected slave units. Then, while effectively using the parent unit and the non-over-connected range of child units, abandon the connection of more child units or select a child unit with a capacity range that does not result in excessive power consumption. It is possible to prompt the user to respond.

Here, the over-connected slave unit is selected in order from the one with the lowest power consumption of the heat source.
It can be avoided that the total power consumption due to the de-energization is reduced.

Moreover, it is provided with the remaining amount detection means to detect the remaining amount of the food, and the further connected slave units are selected in ascending order of the remaining amount.
The effect of reducing the total power consumption due to the de-energization on the food is reduced. Control is performed by wireless communication between the master unit and the slave unit.
In the electrical connection between the master unit and the slave unit, it is not necessary to connect a communication line.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  According to one feature of the method and apparatus for handling food by a plurality of handling devices of the present invention, the handling function of each handling device is activated by energizing each heat source of the plurality of handling devices to cook and keep the food warm. , At least one handling of cold storage can proceed at the same time, it is easy and space-saving, so it can be realized with a safe and inexpensive series connection, and power consumption depends on the number and type of handling devices It is possible to prevent an overcurrent from flowing beyond a predetermined range, thereby preventing the safety of the instrument and causing the electric breaker to operate.

  The power supply to each heat source is performed at a non-overlapping non-overlapping timing. According to a further configuration, it is possible to avoid the overcurrent flow with simple control, and the difference in power consumption of individual handling devices by time distribution of power supply. Can be used according to the requirements

  According to another feature of the method and apparatus for handling food by the multiple handling device of the present invention, the handling function of each handling device is activated by energizing each heat source of the multiple handling devices of the parent unit and the child unit. It is easy and easy to use at least one of cooking, heat insulation, and cold preservation of cooked food, can be realized with a safe and inexpensive series connection without taking up space, and thus without obstructing, and the base point of connection With simple energization control according to the energization amount of the main unit, it is possible to avoid overcurrent flow depending on the type and number of connected child units, and to reduce the power consumption of each handling device by time distribution of energization. Can be used according to differences.

  Control is based on communication information between the master unit and the slave unit connected to it. According to a further configuration, even if the type and number of slave units to be connected are undecided, information by communication from the connected slave unit With the control based on, it is possible to cope with excessive use depending on the type and number of connected slave units.

  In this case, the energization control to the slave unit is such that when the energization amount in the master unit exceeds a predetermined range, the energization of all or all of the slave units is cut off. Even if the number of connections is excessive, it is possible to prompt the user to reconnect the child device while using the parent device, or to promote the response to the excess while effectively using the parent device and the child devices that are not over-connected to the parent device. it can.

  Overconnected slave units are selected in descending order of the power consumption of their heat source. According to a further configuration, the total power consumption can be reduced by energization stop control to increase the effectiveness of the rated power consumption. It is done.

  Moreover, according to the further structure which selects the subunit | mobile_unit of an excess connection in order with few remaining amount of a foodstuff, the influence on the foodstuff of the electricity supply stop for an excessive connection reduces.

  Control is performed by wireless communication between the master unit and the slave unit. According to a further configuration, electrical connection between the master unit and the slave unit is only a hardware circuit.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 18 for the understanding of the present invention. The following description is a specific example of the present invention, and does not limit the scope of the claims.

  In this embodiment, one example is shown in FIG. 1 and FIG. 2, in which a plurality of handling devices 1 are connected in series with wiring 10 as shown in FIGS. The respective heat sources 11 are energized, and the respective heat sources 11 are provided while handling at least one of cooking, heat insulation, and cold insulation for the food. At that time, one of a plurality of handling devices 1 is set as a parent device 2, and the parent device 2 including the child devices 3... Which are one or more other handling devices 1 connected to the parent device 2 in series. The energization of the slave unit 3 .. is controlled according to the energization amount of. In the example shown in the drawing, electricity is supplied using a heater serving as a heat source as the heat source 11 by power supply using the wiring 10, and the cooked food is heated by the heat generated at that time to perform cooking or heat retention. However, a cooling and freezing function using a Peltier element, a refrigeration mechanism, etc. can be employed to exhibit cooling and refrigeration functions. That is, it can also be kept cold. As shown in FIG. 1 (a), the parent unit 2 and the child unit 3 are provided so that the shallow container 41 and the deep container 42 can be attached and detached, and these are heated by the individual heat source 11, In FIG.1 (b), the heat source 11 is collectively shown in one figure. However, the number and types of containers in the parent unit 2 and the child unit 3 and the relationship with the heat source 11 can be freely set.

  In the energization method as described above, one or more slave units 3 are connected in series by wiring 10 with the master unit 2 of the plurality of handlers 1 as a base point, and the heat sources 11 are energized to each The handling function of 1 can be started up, and at least one handling of cooking, heat insulation, and cold preservation for the cooked food can be performed simultaneously. At this time, the total power consumption for starting up the heat sources 11 of the plurality of connected handling devices 1 is reflected in the energization amount in the parent device 2 that is the base point of energization, and this is determined according to the energization amount monitored. Since energization to the device 3 is controlled, it is possible to avoid excessive current consumption due to excessive power consumption depending on the type and number of the child devices 3 connected to the parent device 2. As a result, it is easy to start up the handling function of each handling device 1 by energizing each heat source 11 of a plurality of handling devices 1 and to proceed with at least one handling of cooking, keeping warm, and keeping cold at the same time. It can be realized with a safe and inexpensive series connection that does not take up space and therefore does not get in the way. Moreover, depending on the number and type of handling devices 1 connected, the amount of power consumption exceeds a predetermined range, preventing overcurrent from flowing, preventing the safety of the instrument and causing the electric breaker to operate. can do.

In order to achieve such a method, as a handling apparatus for handling a cooked food by connecting a plurality of handling devices 1 in series, as shown in FIG. A plurality of handling devices 1 having at least one handling function of cooking, heat insulation, and cold keeping, one handling device 1 as a parent device 2 and one other handling device 1 as a child device 3 or one of them As described above, the power supply circuit 12 is connected to the series by the wiring 10 and the heat sources 11 are energized in parallel with the base unit 2 as a base point, and each energization includes the sub unit 3 in the base unit 2 and the power unit 12 in the base unit 2. And a control means 13 for controlling energization to the slave unit 3 according to the above. The control means 13 is provided in the master unit 2, monitors the current supply amount of the power supply circuit 12 by the current transformer 14 for the power supply control, and supplies power to the heat source 11 of the child device 3 based on the detected current supply amount. To control.

  In the example shown in FIG. 1B, this energization control is performed on the parent device 2 side in the power feeding circuit 12 when the energization amount in the parent device 2 exceeds the predetermined power consumption range and an overcurrent is lost. The switch element 15 provided after the connection portion of the heat source 11 is opened to cut off the energization of all the slave units 3. In this way, by turning off the energization of all the slave units 3, it is possible to prompt the user to reconnect the slave unit 3 while using the master unit 2. In order to make this easy to notice, the control means 13 makes a warning by operating the buzzer 16. Further, when the master unit 2 is provided with an operation panel 17 for main switch, temperature adjustment, operation mode setting, etc., a visual warning can be given using the operation panel 17 or the like. FIG. 5 is a flowchart showing such a specific control example.

  Here, the control as described above is performed by the communication means 21 and the communication means 22 as shown in the example of FIG. 3 between the master unit 2 and one or more slave units 3, 3,. Based on the information, the switching means 22a including the switching member of each slave unit 3 can be operated to perform the switching. Thereby, the connection state of the child device 3 to the parent device 2 can be known in the parent device 2 by communication from the connected child device 3, and the connection state of the child device 3 to the parent device 2, that is, connected. Even if the type and number of the sub unit 3 are undecided, each time the sub unit 3 is connected, the connection fact and type are monitored from the connected sub unit 3 and the connection exceeds a predetermined power consumption range. It is possible to immediately determine whether it is a use condition in which an overcurrent flows, and it is possible to control energization so as not to exceed a predetermined power consumption range without monitoring the energization amount in the parent device 2 as described above. In this case, the energization control to the slave unit 3 is such that when the energization amount in the master unit 2 exceeds a predetermined range, all the energization of the slave unit 2 is cut off, and the energization to the over-connected slave unit 3 is performed. You can just cut it off. As a result, while effectively using the parent device 2 and the child device 3 in the range that is not excessively connected to the parent device, the connection of the further child devices 3 is abandoned or the child device is in a capacity range that does not cause excessive power consumption. It is possible to prompt the user to select 3 to continue. For this purpose, it is preferable that the control means 13 gives an audible or visual warning as described above.

  In addition, if the number of rated connections allowed by the slave unit 3 is stored in the control means 13, as shown in FIG. Can be turned off and warning processing can be performed. In addition, if the maximum energization amount corresponding to the rated capacity of the wiring 10 for connecting to the commercial power source 18 shown in FIG. Corresponding to the fact that the type and number of the child devices 3 to be connected one after another are unspecified, it becomes a use condition in which overcurrent flows exceeding the maximum power consumption depending on the type and number of the child devices 3 to be connected one after another. It can respond automatically.

  The subunit | mobile_unit 3 which stops electricity supply by becoming such an excessive connection may be performed corresponding to every group, and can be selected in an order from the thing with small power consumption of the heat source 11 as one example. . Thereby, it can avoid that the total power consumption by an energization stop reduces suddenly. Moreover, when the container to be energized is energized with priority given to the handling device 1 that handles the cooking of the soup, it is easy to ensure the handling conditions suitable for high temperature insulation. Control by communication as described above can be performed by wireless communication between the communication units 21 and 22 between the parent device 2 and the child device 3, and thereby the electrical connection between the parent device 2 and the child device 3. In this case, it is not necessary to connect the communication line, and only the wiring 10 of the power feeding circuit 12 described above is required. The communication unit 21 of the master unit 2 may be equipped with a communication function in the control unit 13 such as a microcomputer, but the slave unit 3 can be easily realized by mounting an IC tag with a wireless communication function. . Moreover, it is provided with the remaining amount detection means which detects the remaining amount of foodstuffs, such as a weight sensor and an optical sensor, and it can also be made to select the subunit | mobile_unit 3 of an excess connection in order with little remaining amount, As a result, by energization stop The impact on the cooked food of the total power consumption reduction is reduced. In addition, if the slave unit 3 is equipped with a main switch, an operation panel 23 for temperature adjustment, etc., the use by the operation, whether it is not used, the difference in the set temperature, etc. are reflected in the energization control as communication information. be able to.

  Further, as in the example shown in FIG. 3 and the example shown in FIG. 4, selection and control information from the control means 13 set in advance on the operation panels 17 and 23 of the parent device 2 and the child device 3 and set by the user. The heat source 11 of the master unit 2 or the slave unit 3 is switched by the switching means 13a of the master unit 2 according to the detected temperature information about the handling temperature from the temperature sensor 24 provided in the master unit 2 or the slave unit 3 or the temperature of the heat source 11. The energization control can be performed in a necessary state at any time by the switching means 22a of the slave unit 3.

  For these wireless communication controls, power supply to the communication means 22 by an IC tag or the like needs to be ensured regardless of whether the heat source 11 of the slave unit 3 is turned on or off and the control state changes, but a backup power source is adopted. If so, no special wiring is required. In addition, if necessary, the slave unit 3 can also be provided with a simple control circuit that cooperates with the communication means 22.

  By the way, the wiring 10 between the parent device 2 and the child device 3 in the power feeding circuit 12 and the wiring 10 between the child device 3 and the child device 3 connect the necessary number of child devices 3 to the parent device 2, and In order to be able to release it, as shown in FIGS. 1, 3, and 4, the leading connector is a magnet plug 31, and the trailing connector is a magnet plug receiver 32, using magnetic attraction. It is easy to connect and disconnect. Such magnetic attraction is performed using the magnetic body 34 shown in FIG. 2A and the magnet 35 and the magnetic body 36 shown in FIG. Since the connection tool is the magnet plug 31, the connection terminal 31a shown in FIG. 2B is connected to the power supply side, and the connection with the rear-side magnet plug receiver 32 is not performed. However, since the connection terminal 31a is retracted into the small connection hole 31c opened in the plug end surface 31b, it is possible to avoid a risk of being touched by mistake or mischief. The magnet plug 31 in the child unit 3 that is idle without being connected, and the magnet plug receiver 32 is dangerous because it is not connected to the power supply even if the connection terminal 32a shown in FIG. It will never be. As described above, since the upper-side connector is the electrically safe magnet plug 31 in the non-connected state, there is a safety problem even if the rear child unit 3 is not connected and exposed. In addition, the magnetic plug receiver 32 of the idle child unit 3 that is not connected is not exposed in a state where it is connected to the power source side, and there is no danger as well. In addition, in the master unit 2, the wiring 10 connected to the commercial power supply 18 has an insertion plug 33 for the connection. Further, the wiring 10 may be connected to the master unit 2 so as to be detachable by the magnet plug 31 and the magnet plug receiver 32.

  The connection terminal 31a of the magnet plug 31 is spring-biased so as to always protrude to the position shown in FIG. 2B, and in the connection state where the magnetic bodies 34 and 36 are attracted by the magnet 35, The connection terminal 31a on the magnet plug 31 side is pushed against the spring bias by the connection terminal 32a on the magnet plug receiver 32 side, and sufficient electrical contact is achieved by the pressure contact with each other by the return behavior to the protruding position by the spring bias. The connection status is secured.

  In addition, as another energization control, a plurality of handling devices 1 are connected in series with the wiring 10 to energize each heat source 11, and each heat source 11 handles at least one of cooking, keeping warm, and keeping cold. The heat source 11 is turned on and off by the control means 13 on the power supply circuit 12 so that the total power consumption at that time is within a predetermined power consumption range. Even if the power consumption necessary for handling the cooked food in the handling device 1 is satisfied, the handling function of each handling device 1 is started up to prepare at least one of cooking, heat insulation, and cold keeping for the cooked food. While simultaneously handling, each heat source 11 is on / off controlled so that the total power consumption at that time is within a predetermined power consumption range, so that the power consumption exceeds the predetermined range and an overcurrent is generated. It flows It is possible to prevent such things.

  FIG. 7 shows an example of such control. As an example, the control corresponds to the fact that the number and type of the slave units 3 to be connected are undecided. If there is connection of the child device 3, it is determined whether or not the number of connections x is equal to or less than a preset rated number. If it is not less than that, the energization of all the child devices 3 due to excessive connection or excessive connection is turned off. Then, warn and wait for the response while returning. If it is below, the heat source capacity w1 · wx of the connector 3 is taken in by an appropriate number. Next, the energization time is distributed so as not to overlap according to the difference in the heat source capacity w1 ·· wx of each slave unit 3, and the respective power consumption amounts W1 ·· Wx are calculated. When the calculated total power consumption W is larger than the preset rated power consumption W0, all the slave units 3 or excess power is turned off to warn and return to use the master unit 2 or the master unit 2 And the use of the subunit 3 within the predetermined capacity range is continued. When the total power consumption W is equal to or less than the rated power consumption W0, energization is performed for each time allocated to the parent device 2 and the child device 3.

  Here, if the energization time distribution to each heat source 11 is set at an extraordinary timing that does not overlap as in the example shown in the time chart of FIG. 8, the parent device 2 is caused by excessive power consumption by simple control of only the distribution of the energization time. As shown in FIG. 8, it is possible to deal with the difference in power consumption required for each heat source by providing a difference in distribution time as shown in FIG.

  Further, in another control example shown in FIG. 9, if the slave unit 3 is not connected, the master unit 2 is normally energized to be in a normal use state. If there is connection of the child device 3, it is determined whether or not the number of connections x is equal to or less than a preset rated number. If it is not less than that, the energization of all the child devices 3 due to excessive connection or excessive connection is turned off. Then, warn and wait for the response while returning. When the following is set, the appropriate number of set temperatures T1... Tx of the connector 3 and the necessary heat source capacities w1. Next, a fixed energization time t is determined when the total power consumption W of the set required heat source capacity w1 · wx is equal to or less than the rated power consumption W0. Next, after the respective heat sources 11 are energized with the necessary heat source capacities for the determined energization time, the detected temperatures of the temperature sensors 24 of the parent unit 2 and the child units 3 are taken in, and the respective set temperatures T1. The difference ΔT1 ·· ΔTx is calculated. The energizer is energized by time corresponding to the magnitude of the difference in order from the handling device 1 having the large difference. Thereafter, the energization for a certain time and the energization for the time corresponding to the magnitude of the difference are repeated in order from the largest difference with respect to the set temperature thereafter, at the temperature set in the master unit 2 and the slave unit 3. The food is handled. According to this, the total power consumption W exceeds the rated power consumption W0 and the overcurrent flows in the master unit 2 while enabling the handling of the cooked food at the set temperature in the master unit 2 and the slave unit 3. Can be prevented.

  In the example shown in FIG. 10, in order to use two or more handlers 1 connected in series by wiring 10, each heat source 11 is automatically set for a certain period of time by the timer switch 51 or each handler. The power is switched automatically every time in proportion to the size of the heat source capacity of 1, and a thermal reed switch 52 is connected to the heat source 11 of each handling device 1 so as to maintain a constant temperature. According to this, the total power consumption W exceeds the rated power consumption W0 and the overcurrent flows in the master unit 2 while handling the cooked food having the set temperature by the set heat source capacity in each handling device 1. Can be prevented.

  In the example shown in FIG. 11, whether each container 1 is equipped with a shallow container 41 as shown in FIG. 11A or a deep container 42 as shown in FIG. Whether or not both are mounted is detected by proximity switches 61 and 62, and the energization is changed depending on the difference between them. Specifically, the heat source 11 is supported so as to be able to respond to the difference in depth between the containers 41 and 42. If the container is not mounted as shown in FIG. However, if the container is not installed and the shallow container 41, the soup and soup are stored in the deep container 42 and the heat source 11 is energized so as to increase the temperature and cool the soup. When the shallow container 41 is considered to contain solids, the heat source 11 is energized so as to maintain the lower temperature, and the solids are The food is eaten without being dried or burnt.

  The example shown in FIG. 13 and FIG. 14 is a shoulder heater type in which the container mounted around the opening 161 for accommodating the shallow container 41 and the deep container 42 in the handling device 1 is received by its flange portion as shown in FIG. As shown in FIG. 13, while the optical sensor 63 provided in the handling device 1 detects the container and outputs a dark signal, the energization of the heat source 11 corresponding to the container is continued. When a bright signal is issued without detecting the container due to the removal of the cooked food, the energization of the corresponding heat source 11 is turned off and a warning is issued. As a result, it is possible to prevent energizing the dangerous heat source 11 without using a container. However, the container can be detected by proximity switches 61 and 62 as shown in FIG. 11 without making the container transparent.

  Here, the container to be mounted can be made transparent, and the presence or absence of the cooked food can be detected by the optical sensor 63, and the heat source 11 without the cooked food can be controlled to be turned off and warned.

  In the example shown in FIGS. 15 and 16, as shown in FIG. 15, containers to be mounted are disposed at two opposite positions around the opening 161 that accommodates the shallow container 41 and the deep container 42 in the handling device 1. Weight sensors 71 and 72 received by the flange portion are provided, and as shown in FIG. 16, the two weight sensors 71 and 72 detect that the container is properly attached only after detecting the container, and first energize, and then the two weight sensors 71 , 72 detects a predetermined light weight, it is accurately determined that the food has become empty without being affected by the bias of the cooked food, the power is turned off, a warning is given, and the process returns.

  17 and 18, the heat source 11 and the weight sensor 81 are adjusted to an appropriate height to the depth of the container mounted by the height adjusters 82 and 83, as shown in FIG. As shown in FIG. 18, when the container is present, the weight is measured, and if the amount is not increased from the previous measurement, the cooked food is not replenished. If the remaining amount is not less than the predetermined remaining amount, it returns as it is, and when it is less than the predetermined remaining amount, the replenishment is wirelessly communicated to the kitchen and the replenishment is urged to make it difficult to invite the remaining amount. Considering the delay in replenishment, it is next determined whether there is no remaining amount. If there is no remaining amount, the power is turned off and a warning is issued. If the increase is determined after the weight measurement, the food has been replenished, so the timer count is reset and the process returns. According to this, even if an opaque container is used, the remaining amount and the presence / absence of the food can be determined and dealt with.

  Note that a warmer is normally set to 150 to 200 W of power consumption, but if such a normal setting value is used to maintain a predetermined set temperature by energization based on time sharing as described above, As a result, the total energization time for setting the temperature becomes difficult to increase, and as a result, the number of connections of the handling devices 1 that can take the shared energization time is likely to be limited. Therefore, if it is set higher than the normal set value, the required energization time is shortened, and it is easy to take the shared energization time, and the number of connections of the handling device 1 is easily increased. Specifically, it is preferable to set the power consumption of the heat source 11 to about 500 W or more. However, it is not limited to this.

  The present invention can be practically used to supply multiple people while handling multiple types of cooked food with individual handling equipment such as cooking, heat insulation, cold preservation, etc., and connecting multiple handling equipment to a series for easy use Can be done properly.
