Japanese Patent Application Publication No. 2009-156562

In the kitchen, multiple heat generating devices may operate simultaneously. The present specification provides a technique that can drive a ventilator with an appropriate air volume even when a plurality of heat generating devices are operated.

The kitchen ventilation system disclosed herein includes a ventilation device that ventilates a kitchen in which a cabinet and a plurality of heat generating devices are installed , and a controller that controls the ventilation device. The cabinet is capable of accommodating a first heat generating device included in the plurality of heat generating devices. The cabinet consists of an exhaust device that exhausts the air inside the cabinet to the outside, a top plate, an exhaust port installed on the top plate that exhausts the air inside the cabinet to the outside, and a heating cooker included in the heating device. It is equipped with a heating cooker placed above the top plate. The heating cooker includes a burner and the through hole for exhaust treatment of the first heat generating device and connected to the exhaust port. The through hole is the same as the air supply port that supplies air to the burner. The controller acquires operating information or operating information of at least the first heat generating device and the heating cooker , and determines the air discharge volume of the ventilation device and the exhaust device based on the operating information or operating information. Since the air discharge volume is determined based on the operating information or operation information of the plurality of heat generating devices, the ventilation device and the exhaust device can be driven with appropriate air volume even when the plurality of heat generating devices are operating. Typical heat generating devices are cookers or dishwashers. Three or more heat generating devices may be included.

The cabinet is equipped with a sensor that measures one of the temperature and humidity inside the refrigerator as operation information of the first heat generating device, and the controller determines the air discharge volume of the ventilation device based on the operation information or the sensor information. You can. Even if the first heat generating device does not have a function of transmitting its own operating information, the air discharge volume can be determined based on the operation information according to the operating state of the plurality of heat generating devices including the first heat generating device.

The cabinet includes an exhaust device that exhausts air inside the refrigerator to the outside, and the controller may control the exhaust device based on the measured value of the sensor. The controller also controls the exhaust system as well as the ventilation system. High-temperature air inside the cabinet can be quickly exhausted outdoors.

The ventilation device is located above the cooking device, and a transmitter that sends a signal generated by the controller to the ventilation device may be located in the cooking device. In the kitchen, a heating cooker with multiple stove burners and a ventilation system are often installed as a set. The ventilation device is placed above the cooking device. By attaching the transmitter to the cooking device closest to the ventilation device, the reliability of signal transmission to the ventilation device is improved.

The controller stores weight information corresponding to each type of the plurality of heat generating devices, and may determine the air discharge volume based on the operation information or operation information and weight information of the plurality of heat generating devices. For example, a large weight is set for rice cookers and dishwashers that generate high-temperature steam. When the rice cooker or dishwasher starts, the controller immediately starts the ventilation system at maximum airflow. On the other hand, a small weight is set for a heat generating device that generates little steam. If such a heat generating device is activated, the controller will initially activate the ventilation system with a small air volume. A more appropriate air discharge volume can be determined depending on the type of heat generating device.

Details and further improvements of the technology disclosed in this specification will be explained in the following "Detailed Description of the Invention".

It is a top view of the modification of the heating cooker incorporated into the cabinet. FIG. 7 is a cross-sectional view of another modified kitchen ventilation system.

A kitchen ventilation system 5 according to an embodiment will be described with reference to the drawings. FIG. 1 shows a front view of the kitchen ventilation system 5. The kitchen ventilation system 5 includes a cabinet 20 that is installed in the kitchen K and forms a part of the system kitchen 2, and a ventilation device 10 that is installed above the cabinet 20. Although the system kitchen 2 has a configuration in which a plurality of cabinets including the cabinet 20 are connected, a description of other cabinets other than the cabinet 20 will be omitted. A countertop 3 is installed above the cabinet 20 and another cabinet adjacent thereto. By installing the counter top 3, a plurality of cabinets are integrated.

FIG. 2 shows a plan view of the cabinet 20. The cabinet 20 is a cabinet dedicated to a heating cooker in which a heating cooker 40 having a plurality of stove burners 42 and a grill storage 43 is incorporated. In addition, in FIG. 1 and subsequent figures, illustration of the trivet arranged on the stove burner 42 is omitted.

The heating cooker 40 is housed in the cabinet 20 with a main body 41 disposed under the countertop 3, a top plate (cooker top plate 44) attached from above.

As shown in FIG. 2, the cabinet 20 is installed along the wall 90 of the kitchen K. An opening 45a is provided at the rear of the cooker top plate 44. The opening 45a corresponds to the upper opening of the through hole 45 that vertically penetrates the heating cooker 40. The through hole 45 will be described later. Upper end openings of an exhaust pipe 25 (described later) and an internal exhaust passage 49 (described later) are located inside the opening 45a (through hole 45). The opening 45a is covered with a lid having, for example, mesh-like or slit-like holes, but the lid is not shown.

Further, a controller 30 and a transmitter 31 are arranged inside the heating cooker 40. The controller 30 and transmitter 31 will also be described later. In addition, in the figure, the controller 30 and the transmitter 31 are arranged inside the heating cooker 40, but the controller 30 and the transmitter 31 may be arranged in the cabinet 20 or in another cabinet. Good too. The controller 30 and the transmitter 31 may be placed in separate devices (or cabinets). Controller 30 may be placed in a room other than the kitchen. In the case of the embodiment (FIG. 2), the transmitter 31 is located below the gap between the opening 45a of the cooker top plate 44 and the exhaust pipe 25.

Returning to FIG. 1, the explanation of the cabinet 20 will be continued. The cabinet 20 includes a storage 22 below the cooking device 40. An opening 22a is provided at the front of the cabinet 20 for the user to access the inside of the storage 22, and the opening 22a is closed with a door 21. The storage 22 (opening 22a) can be opened and closed by the door 21. Various devices can be placed in the storage 22. The cabinet 20 is equipped with an exhaust device so that a heat generating device such as a heating cooker or a dishwasher can be stored and used in the storage 22. The exhaust device will be described later.

A ventilation system 10 is provided above the cabinet 20. The ventilation device 10 can exhaust air from the kitchen K to the outdoors. The ventilation device 10 is a propeller-type ventilation fan provided on the wall of the kitchen K, but a sirocco-type ventilation fan may also be adopted. A range hood 11 is attached around the ventilation device 10 to collect high-temperature air generated from the cooking device 40. The ventilator 10 includes a receiver 12 and operates upon receiving commands from the controller 30 through the receiver 12 and the transmitter 31.

FIG. 3 shows a cross-sectional view taken along line III-III in FIG. 1. FIG. 3 shows an example in which heat generating devices 81 and 82 are housed in the storage 22. An example of the heat generating devices 81 and 82 is a rice cooker, an automatic cooking pot, a dishwasher, or the like. The internal structures of the heat generating devices 81 and 82 are omitted from illustration. When both the heat generating devices 81 and 82 operate, they discharge high temperature air and the like. In order to prevent high-temperature air, etc. (especially smoke and steam) from being trapped inside the storage 22, the storage 22 is equipped with an exhaust pipe 25 that discharges the air, smoke, and steam inside the storage 22 to the outside. and an exhaust device 26 are arranged.

An exhaust port 24 is provided at the rear of the top plate 23 of the cabinet 20 (the top plate 23 corresponding to the top surface of the storage 22). Note that a heating cooker 40 is arranged above the top plate 23. A through hole 45 passing through the cooking device 40 in the vertical direction is provided at the rear of the cooking device 40 . The through hole 45 includes an opening 45a provided in the cooker top plate 44 and a lower through hole 45b provided in the main body 41 of the cooking device 40. The through hole 45 of the cooking device 40 is connected to the exhaust port 24 of the top plate 23. The through hole 45 of the cooking device 40 overlaps the exhaust port 24 in the vertical direction, and the exhaust pipe 25 passes through the exhaust port 24 and the through hole 45. The exhaust device 26 is a sirocco fan, and when the exhaust device 26 operates, air inside the cabinet 20 (air in the storage 22, etc.) is discharged to the outside through the exhaust pipe 25 (that is, the exhaust port 24 and the through hole 45). (that is, the space of kitchen K).

A large opening is provided in the counter top 3 of the system kitchen 2, and the opening 45a of the cooking device 40 as well as the plurality of stove burners 42 are opened upward. That is, the exhaust pipe 25 also passes through the opening of the counter top 3.

The heating cooker 40 includes a grill chamber 43 as a heating chamber and an internal exhaust passage 49. The internal exhaust passage 49 connects the internal space of the grill storage 43 and the through hole 45. High temperature air generated inside the grill chamber 43 is discharged to the kitchen K through the through hole 45 (opening 45a). The through hole 45 serves both as a flow path for discharging air and the like inside the grill storage 43 and a flow path for discharging air and the like inside the storage storage 22. By sharing the exhaust ports for smoke emitted from two locations, the number of exhaust ports is reduced and the aesthetic appearance of the cabinet 20 (cooking device 40) is improved.

The rear surface of the storage 22 (the rear plate 32 of the cabinet 20) is provided with a temperature sensor 27 that measures the temperature inside the storage and a humidity sensor 28 that measures the humidity inside the storage. Measured values from the temperature sensor 27 and humidity sensor 28 are sent to the controller 30. The controller 30 controls the exhaust device 26 based on the measured values of the temperature sensor 27 and humidity sensor 28. Since the measured values of the temperature sensor 27 and the humidity sensor 28 indicate the state of the air inside the storage 22, these measured values may be referred to as warehouse interior information below. The warehouse information is one type of operation information of the heat generating devices housed in the storage 22 . The controller 30 controls the ventilation device 10 as well as the exhaust device 26 based on the inside information. That is, the exhaust system 26 and the ventilation system 10 are controlled in conjunction. The main body of the cooking device 40 is equipped with a transmitter 31, and commands from the controller 30 are sent to the ventilation device 10 through the transmitter 31 and receiver 12. The controller 30 generates a command signal to the ventilator 10 based on the operating information of the heat generating device or the inside information of the refrigerator, and the transmitter 31 transmits the generated command signal to the receiver 12 (ventilator 10). The controller 30 can also issue a command signal to the exhaust device 26 through a communication function (not shown). The exhaust system 26 and the ventilation system 10 operate based on commands from the controller 30.

The controller 30 causes the exhaust system 26 and the ventilation system 10 to work together. For example, the controller 30 simultaneously activates the exhaust device 26 and the ventilation device 10 when the temperature inside the refrigerator exceeds a predetermined temperature threshold or when the humidity inside the refrigerator exceeds a predetermined humidity threshold. The air exhausted above the cabinet 20 by the exhaust device 26 is exhausted outdoors by the ventilation device 10 located above the cabinet 20. By activating the exhaust device 26 and the ventilation device 10 at the same time, the air inside the refrigerator is quickly exhausted to the outdoors.

The amount of air discharged outside the refrigerator (ie, the output) of the exhaust device 26 can be adjusted to three levels: Low, Middle, and High. The air discharge volume of the exhaust device 26 increases in the order of Low, Middle, and High. The amount of air discharged outdoors from the ventilation device 10 can also be adjusted to three levels: Low, Middle, and High. The air discharge volume of the ventilation device 10 increases in the order of Low, Middle, and High. The low air discharge volume of the ventilation device 10 is larger than the low air discharge volume of the exhaust device 26. Similarly, the middle (high) air discharge volume of the ventilation device 10 is larger than the middle (high) air discharge volume of the exhaust device 26 . Controller 30 operates ventilator 10 at a level equal to or higher than the level of exhaust system 26 . That is, the controller 30 controls the ventilation device 10 and the exhaust device 26 so that the amount of air discharged outdoors by the ventilation device 10 is greater than the amount of air discharged outside the warehouse by the exhaust device 26.

When the heating cooker 40 disposed above the cabinet 20 is in use, the ventilation device 10 may be activated by a user's operation. Alternatively, the controller 30 may start the ventilation device 10 when detecting the operation of the cooking device 40. If at least one of the heat generating devices 81 and 82 stored in the storage 22 is not operating, the exhaust device 26 is stopped. When at least one of the heat generating devices 81 and 82 in the storage 22 is activated while the ventilation device 10 is in operation, and the temperature inside the storage 22 increases or the humidity increases, the controller 30 controls the ventilation device 10. The exhaust device 26 is started while the is operating.

When the ventilation system 10 is operating at a low level, the controller 30 activates the exhaust system 26 at a low level. When the temperature inside the storage 22 further increases or the humidity inside the storage exceeds the humidity threshold, the controller 30 switches the levels of both the ventilation device 10 and the exhaust device 26 from Low to Middle. That is, as described above, the controller 30 controls the ventilation device 10 and the exhaust device 26 in an interlocked manner so that the amount of air discharged from the ventilation device 10 to the outside is greater than or equal to the amount of air discharged from the exhaust device 26 to the outside. do.

If the cooking device 40 is not in use and the temperature or humidity inside the storage 22 is not very high, the controller 30 may start the exhaust device 26 while stopping the ventilation device 10. When the temperature or humidity inside the refrigerator becomes high, the controller 30 starts the ventilation device 10 while leaving the exhaust device 26 operating.

The cabinet 20 is equipped with an opening/closing sensor 29 that detects whether the door 21 of the storage 22 is opened or closed. When the controller 30 detects that the door 21 is opened while the exhaust device 26 and the ventilation device 10 are operating, the exhaust device 26 is stopped while the operation of the ventilation device 10 is maintained. When the door 21 is opened, the air inside the storage 22 is exhausted from the opening 21a, so the exhaust device 26 may be stopped. If the exhaust device 26 is stopped, an increase in electricity costs can be suppressed. However, since the controller 30 maintains the operation of the ventilation system 10, the air exiting to the kitchen K through the opening 21a is quickly exhausted outdoors.

A heat generating device (for example, heat generating device 82) housed in storage 22 may include a communication device 84. The heat generating device 82 can transmit operating information including information such as activation, operating status, and stoppage to the controller 30 using the communication device 84 . Note that the operating state refers to, for example, in the case of a rice cooker, the state of rice cooking, steaming, etc. Alternatively, in the case of a dishwasher, the operating state is, for example, washing, rinsing, drying, etc. When the heat generating device 82 is equipped with the communication device 84, the controller 30 directly obtains operating information from the heat generating device 82, and simultaneously controls the exhaust system 26 and the ventilation system 10 based on the obtained operating information. Good too. For example, when the heat generating device 82 is a dishwasher, when the controller 30 receives a signal indicating that the dishwasher (heat generating device 82) has started operating, the controller 30 simultaneously sets the exhaust device 26 and the ventilation device 10 to the air exhaust air volume level Low. Start with .

In addition to the heat generating device 82 that has a communication function, the storage 22 may also include a heat generating device that does not have a communication function (for example, the heat generating device 81). The controller 30 controls the exhaust system 26 and the ventilation system 10 based on the operating information obtained from the heat generating device 82, and also controls the inside information obtained from the temperature sensor 27 or humidity sensor 28 installed inside the storage 22. The exhaust system 26 and the ventilation system 10 may also be controlled based on the following. For example, the controller 30 obtains operating information from the heat generating device 82 and simultaneously activates the exhaust device 26 and the ventilation device 10 at an air exhaust volume level of Low. Thereafter, when a temperature rise in the storage 22 is detected based on the internal information, the controller 30 simultaneously changes the level of the air discharge volume of the exhaust device 26 and the ventilation device 10 from Low to Middle.

FIG. 4 shows a plan view of a modification of the heating cooker (heating cooker 140) that is incorporated into the cabinet 20. The heating cooker 140 includes a stove burner 42 and an air supply port 149 that supplies primary air to the stove burner 42. The air supply port 149 is the same as the through hole 45. In other words, the opening 45a of the through hole 45 also serves as the air supply port 149. The heating cooker 140 can supply primary air to the stove burner 42 through the through hole 45 and the air supply port 149. In the heating cooker 140 of the modified example, the through hole 45 serves both as an outlet for discharging the air from the storage 22 to the outside of the storage and as a hole for taking in the primary air of the stove burner 42. Since the number of holes can be reduced, the appearance of the heating cooker 140 is also improved.

The processing of the controller 30 will be explained. As described with reference to FIG. 3, the controller 30 controls the ventilation device 10 and the exhaust device 26 based on the operation information or operation information of the plurality of heat generating devices. The controller 30 may control the ventilation device 10 and the exhaust device 26 based on inside information, which is one type of operation information. In the case of FIG. 3, the controller 30 receives operating information directly from the cooking device 40 and the heat generating device 82. The controller 30 uses the measured values (interior information) of the temperature sensor 27 and humidity sensor 28 installed in the storage 22 as a means of knowing the operating information indicating the operating state of the heat generating device 81 that does not have a communication function. . The controller 30 determines the air discharge volume of the ventilation device 10 and the exhaust device 26 based on at least one of the operation information of the plurality of heat generating devices (heating cooker 40 and heat generating device 82) and the inside information of the refrigerator, and the determined air discharge amount. The ventilation device 10 and the exhaust device 26 are simultaneously controlled so that the air volume is achieved. Note that as the operating information instead of the refrigerator interior information, the operating state known from the temperature of the heat generating device by an infrared sensor may be used.

The heating device 81 and the heating device 82 are located inside the storage 22, and the cooking device 40 is located outside the storage. It is registered in the controller 30 in advance that the heating cooker 40 is located outside the refrigerator. The controller 30 determines the air discharge volume of the exhaust device 26 based on the operation information of the heat generating device 82 inside the refrigerator and the inside information of the refrigerator. The controller 30 determines the air discharge volume of the ventilation device 10 based on the operation information of the heat generating device 82 inside the refrigerator, the inside information of the refrigerator, and the operation information of the heat generating device outside the refrigerator (cooking device 40).

For example, based on the operating information of the heat generating device 82 inside the refrigerator and the information inside the refrigerator, the controller 30 determines the level of the air discharge volume to be Middle. The controller 30 adds the operation information of the heat generating device outside the refrigerator (heating cooker 40) to the operation information of the heat generating device 82 inside the refrigerator and the information inside the refrigerator, and sets the level of the air discharge volume of the ventilation device 10 to High. The controller 30 determines the air discharge volume of the ventilation device 10 to be larger than the air discharge volume of the exhaust device 26 when heat generating devices are operating inside and outside the refrigerator.

As a modification of the process executed by the controller 30, the controller 30 stores weight information according to the types of a plurality of heat generating devices, and controls air discharge based on the operation information of the plurality of heat generating devices or the inside information and the weight information. The air volume may also be determined. For example, if the heat generating device 82 is a small rice cooker with low output, the weighting coefficient is set to "1", and if the heating device 82 is a large automatic cooking pot with high output, the weighting coefficient is set to "2". Further, for example, a weighting coefficient may be set for the degree of absolute humidity depending on the temperature inside the refrigerator, which is information inside the refrigerator.

The controller 30 receives an activation signal and a signal indicating the type of device (device identification signal) from the heat generating device 82 . The controller 30 determines the type of heat generating device 82 based on the device identification signal, and specifies a weighting coefficient according to the type. If the heat generating device 82 activated in the storage 22 is a small rice cooker with a low output, the controller 30 activates both the exhaust device 26 and the ventilation device 10 at the lowest level, Low, in response to the weighting coefficient “1”. . If the heat generating device 82 activated in the storage 22 is a large automatic cooking pot with a large output, the controller 30 activates both the exhaust device 26 and the ventilation device 10 at the middle level in response to the weighting coefficient “2”. do.

As described above, when the heating cooker 40 located outside the storage 22 is started while the large automatic cooking device is operating inside the storage 22, the controller 30 controls the exhaust system. The level of the air exhaust air volume 26 is maintained at the Middle level, and the level of the ventilation device 10 is switched from Middle to High, which is one level higher.

The kitchen ventilation system 5 can drive each of the exhaust device 26 and the ventilation device 10 with an appropriate air discharge volume based on operation information or operation information of a plurality of heat generating devices operating inside and outside the cabinet 20.

The relationship between the transmitter 31 and the receiver 12 will be explained. In the kitchen ventilation system 5 of the embodiment, the transmitter 31 is placed in a heating cooker 40 placed above the cabinet 20. The transmitter 31 is located below the gap between the opening 45a of the cooker top plate 44 and the exhaust pipe 25. The receiver 12 is located above the opening 45a. The transmitter 31 and the receiver 12 may be radio wave type communication devices with low directivity, or may be optical communication devices with high directionality. In either case, the signal is sent from the transmitter 31 to the receiver 12 through the gap between the opening 45a and the exhaust pipe 25 without being obstructed by the cooker top plate 44. Since the signal is not blocked by the cooker top plate 44, the reliability of communication is high.

Referring to FIG. 5, a cross-sectional view of an alternative kitchen ventilation system 105 is shown. The kitchen ventilation system 105 includes a ventilation device 10 and a cabinet 120, and the ventilation device 10 is the same as the kitchen ventilation system 5 of the embodiment. The kitchen ventilation system 105 differs from the previous cabinet 20 in the arrangement position of the transmitter 131 included in the cabinet 120. Further, the heating cooker 140 built into the upper part of the cabinet 120 does not include a grill compartment inside the main body 141. Therefore, the internal exhaust passage 49 shown in FIG. 3 is not provided. The heating cooker 140 is provided with a through hole 45 (an opening 45a and a lower through hole 45b) that overlaps the exhaust port 24 in the vertical direction, and the exhaust pipe 25 passes vertically inside the through hole 45. Further, as described in FIG. 4, the through hole 45 (opening 45a) also serves as the air supply port 149. The other configuration of the cabinet 120 is the same as the cabinet 20 of the embodiment.

The transmitter 131 is located below the exhaust port 24 provided on the top plate 23 of the cabinet 20. The receiver 12 is arranged above the through hole 45 (exhaust port 24) of the cooking device 140. A thick dotted line indicated by the symbol S in FIG. 5 schematically indicates a signal. The controller 30 generates a command signal to the ventilator 10 based on the operating information of the heat generating device or the inside information of the refrigerator, and the transmitter 131 transmits the generated command signal to the receiver 12 (ventilator 10).

As shown in FIG. 5, the transmitter 131 and the receiver 12 can communicate without being shielded through the exhaust port 24 and the through hole 45. The transmitter 131 sends a signal to the receiver 12 (ventilator 10) through the exhaust port 24 and the through hole 45. Therefore, communication reliability is high. Furthermore, the exhaust port 24 and the through hole 45 serve both as exhaust air from the storage 22 and as a communication path. There is no need to provide a separate hole for communication, and there is no need to increase the number of holes and spoil the appearance.

The transmitter 131 and the receiver 12 may be radio wave communication devices with low directivity, or may be optical communication devices with high directivity that transmit signals using light. Transmitter 131 and receiver 12 can communicate without being shielded. In other words, the reliability of signal transmission is high. The configuration of FIG. 5 is particularly suitable for a kitchen ventilation system that employs an optical communication device. In the case of an optical communication device, the transmitter 131 is installed to face the receiver 12 . A highly directional signal is sent from the transmitter 131 to the receiver 12 (ventilator 10) through the exhaust port 24 and the through hole 45.

Further, the transmitter 131 is attached to the rear plate 32 of the cabinet 120 so as to face the storage 22. When the heat generating device housed in the storage 22 is a cooking device or a dishwasher, there is a risk that moisture may adhere to the floor of the storage 22 . By attaching the transmitter 131 to the rear plate 32 of the cabinet 120, the transmitter 131 can be protected from moisture. A temperature sensor 27 and a humidity sensor 28 are also attached to the rear plate 32 so as to face the storage 22. Temperature sensor 27 and humidity sensor 28 can also be protected from moisture.

As shown in FIG. 2, the transmitter 31 of the kitchen ventilation system 5 of the embodiment is also placed below the gap between the opening 45a and the exhaust pipe 25, so it can communicate with the receiver 12 without being shielded. can do. High reliability of signal transmission.

There are no restrictions on the communication method between the transmitter 31 (131) and the receiver 12. In the case of an optical type, the transmitter 31 (131) and the receiver 12 may be of a type that sends signals by infrared rays, for example. In the case of a radio wave type, the transmitter 31 (131) and the receiver 12 are devices of a short-range wireless communication system or a medium-range wireless communication system (for example, Wi-Fi (registered trademark)) such as Bluetooth (registered trademark). Good too. The communication method between the controller 30 and the communication device 84 of the heat generating device 82 is also not limited, and may be, for example, a Bluetooth (registered trademark) or Wi-Fi (registered trademark) connection method.

Other points to note explained in the examples will be described. The heating cooker 40, 140 may be a table stove placed on the top plate 23. The grill chamber 43 is an example of a heating chamber. The heating cooker 40, 140 may be a gas type or an electric type. In the case of an electric type, the heating cooker 40, 140 may be of an induction heating type. The cabinets 20 and 120 may be other than a system kitchen, for example, a separate type sink.

In the embodiment, the air volume of the ventilation device 10 and the exhaust device 26 can be adjusted in three stages. One or both of the ventilation device and the exhaust device may be of any type as long as the air volume can be adjusted in two or more stages.

The transmitters 31 and 131 may be placed in front of the cooking devices 40 and 140. In FIG. 5, the transmitter 131, the temperature sensor 27, and the humidity sensor 28 are attached to the rear plate 32 of the cabinet 120. The transmitter 131, the temperature sensor 27, and the humidity sensor 28 may be attached to a location other than the rear plate 32.

The techniques described in the claims include various modifications and changes to the specific examples illustrated above. The technical elements described in this specification or the drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims as filed.
