Japanese Patent Laid-Open No. 03-272718

  However, the conventional technique has the following problems.

  As shown in Patent Document 1, in a grill provided with a gas burner as a heating source, in order for the support bar protruding rearward outside the grill to smoothly run on the weighing arm of the weight sensor, the support bar is used. It is necessary that a clearance (clearance) exists between the hole penetrating the rear wall of the grille and the support rod, and the hot air in the grille diffuses toward the weight sensor provided at the rear rear of the grille. Further, the temperature of the weight sensor may increase due to radiant heat from the rear wall of the grill. When the temperature increase is large, there is a possibility that sufficient measurement accuracy of the weight sensor cannot be obtained.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a weight sensor even when a weight sensor is disposed in the vicinity of the rear end wall of the grill in a grill provided with a gas burner as a heating source. It is an object of the present invention to provide a grill that is not easily affected by combustion exhaust from a gas burner, can perform accurate weight measurement, and has excellent controllability.

In order to solve the above-mentioned problem, the first characteristic configuration of the present invention is a burner for heating a food placed on a grill net stored in a grill house stored in a housing; An exhaust passage that discharges cooking exhaust generated by heating due to combustion of the burner from an upper exhaust outlet, a saucer that receives a broth such as oil falling from the cooked product, and the grill net and the cooked product in and out of the front A communication port provided in the rear wall of the grill cabinet, comprising a loading / unloading port, a support that supports the load of the grill net, and a weight sensor disposed outside the grill cabinet inside the housing The weight sensor applies a load applied to the support when the grill net stored from the outlet is located at a predetermined storage position in the front-rear direction in the grill cabinet. Configure to measure In the grill, the area extending from the periphery of the weight sensor to the communication port in the casing is defined as an intake flow path, and the intake flow path is formed from the outside of the casing to the inside of the casing. An intake portion for allowing the inflowing air to flow into the intake passage as intake air is provided in the vicinity of the weight sensor, and during the combustion of the burner, the intake air that has flowed from the intake portion into the intake passage passes through the communication port. A cleaning mode in which heating is performed by burning the burner without storing the grill net and the cooked food in the grill chamber in order to burn off the oil and the like attached to the grill chamber and flowing into the grill chamber, The clean mode is not executed when the load measured by the weight sensor is equal to or greater than a second set value .

  With such a configuration, the cooked exhaust generated by the heating by the combustion of the burner flows through the exhaust path toward the upper exhaust outlet by the draft and is discharged from the exhaust outlet. At this time, a negative pressure is generated in the vicinity of the rear wall in the grill cabinet due to the draft, and the communication port is opened from outside the grill cabinet by forming a communication port in the negative pressure portion. Via, the air in the casing in which the grille is stored can be caused to flow into the grille.

  At this time, when the air in the casing flows into the grill cabinet from the communication port, the pressure in the casing decreases. However, when a burner is used as a heating heat source in the grill, the primary air for burning the burner, Since the casing is provided with a combustion air intake for the burner so that air supplied to the secondary air or the like can be taken into the casing from the outside of the casing, the pressure in the casing is reduced. If it falls, the air outside a housing | casing will flow in into a housing | casing from the intake of the combustion air of the said burner, and the air in a housing | casing will be replenished from the outside of a housing | casing sequentially.

  An area inside the casing that reaches the communication port via the periphery of the weight sensor is defined as an intake flow path. In this intake flow path, air flowing from the outside of the casing into the casing is used as intake air. An intake portion that flows into the intake passage is provided in the vicinity of the weight sensor, and during combustion of the burner, intake air that flows into the intake passage from the intake portion, that is, air outside the housing, flows into the communication port. Since the weight sensor and the support body are cooled by the intake air by flowing into the grill box through the hot air in the grill box diffuses toward the weight sensor provided on the rear side outside the grill box, An increase in the temperature of the weight sensor due to radiant heat from the wall and heat conduction from the support is suppressed, and the measurement accuracy of the weight sensor is maintained high.

  In short, the weight sensor is hardly affected by the heat from the combustion exhaust by the gas burner, and it is possible to make a grill having excellent controllability by performing accurate weight measurement.

  Furthermore, as a second characteristic configuration, a sensor cover is provided that covers the left and right sides and the upper side of the portion of the support that protrudes from the communication port into the housing, and covers the left and right sides and the upper side of the weight sensor, It is preferable that a lower part or a rear part in the vicinity of the weight sensor in the sensor cover is an open part that is not covered by the sensor cover, the open part is the intake part, and a region covered by the sensor cover is the intake passage. .

  In this case, an open portion that is not covered by the sensor cover below or behind the weight sensor is defined as an intake portion, and flows from the open portion (intake portion) and passes through the area covered by the sensor cover, that is, the intake passage. In addition to the weight sensor being cooled by the air, the sensor cover covers the weight sensor and the support above and to the left and right sides. It also has a function of protecting the weight sensor due to the foreign matter and the contamination of the support.

In other words, the second characteristic configuration makes it possible to form an intake flow path having a function of preventing the weight sensor and the support body from being contaminated by foreign matters scattered from above and from the left and right sides of the support body. Become.

  Further, as a third characteristic configuration, an intake hole through which air outside the casing flows into the casing is formed immediately below the weight sensor in the casing, and an intake section is directly above the intake hole. It is preferable that a space around the weight sensor and a space around the support body, which extends from directly above the intake hole to the communication port, serve as the intake flow path.

  In this case, the intake flow path can be configured with a simple configuration in which an intake hole through which air outside the casing flows into the casing is formed just below the weight sensor in the casing.

That is, even when the second characteristic configuration is not provided, when air flows into the casing from the outside of the casing, the air also flows from the intake hole formed directly below the weight sensor. Since it is reasonable that the intake hole drilled immediately below is located on the bottom surface of the housing, the air flowing in from the intake hole flows from the bottom surface of the housing toward the weight sensor located above. Become. After that, the air flowing in from the intake hole flows toward the communication port, and therefore, the air sensor inevitably moves from the intake hole to the weight sensor depending on the relative positional relationship between the intake hole, the weight sensor, and the communication port. Since the air flows into the grille from the communication port via the peripheral space and the space around the support, the intake flow path is formed by forming the intake holes.

  Further, even when the second characteristic configuration is provided, the air flowing in from the intake hole flows from the bottom surface of the housing toward the weight sensor located above, as described above. The body is cooled more efficiently by the intake air, and the measurement accuracy of the weight sensor is maintained higher.

  In short, according to the third characteristic configuration, the intake flow path can be configured with a simple configuration by simply drilling the intake hole, and the measurement accuracy of the weight sensor can be maintained at a higher level. .

  Furthermore, as a fourth characteristic configuration, it is preferable that the support body is provided to project rearward from the rear end of the grill net.

  In this case, the support can be simply configured by projecting backward from the rear end of the grill.

  Furthermore, as a fifth characteristic configuration, it is also preferable that the grill net is placed on the saucer, and the support body protrudes rearward from the rear end of the saucer.

  In this case, that is, when the grill net is placed on the saucer, the support can be easily configured by projecting backward from the rear end of the saucer. Since the body can be selected to project backward from the rear end of the grill net, and the support can be configured to project rearward from the rear end of the receiving tray, the design freedom when configuring the grille can be selected. The degree is increased and the design can be performed easily.

Furthermore, in the first characteristic configuration , a cleaning mode in which heating is performed by combustion of the burner without storing the grill net and the cooked food in the grill chamber in order to burn off the oil and the like attached to the grill chamber can be executed. , the load measured by the weight sensor when more than the second set value is not an executing the clean mode.

Therefore , by setting the second set value to a value that allows the weight sensor to detect a weight that is equal to or greater than the weight of the grill or the total weight of the tray and the weight of the grill, When the user mistakenly executes the clean mode with the grill net stored in the grill cabinet, the grill net can be prevented from being damaged due to empty grill of the grill net, and the usability of the grill is improved.

  According to the first aspect of the present invention, the weight sensor is less susceptible to the heat from the combustion exhaust from the gas burner, and can accurately measure the weight and provide a grill with excellent controllability.

  In addition to the effect of the first aspect, the invention described in claim 2 has a function of protecting the weight sensor and the weight sensor due to foreign matter scattered from the upper side and the left and right sides of the support body and a function of preventing the support body from being contaminated. A flow path can be formed.

  In addition to the effect of the first or second aspect, the third aspect of the present invention is such that an intake hole through which air outside the casing flows into the casing is formed just below the weight sensor in the casing. The intake flow path can be configured with a simple configuration, the weight sensor can be cooled more efficiently, and the measurement accuracy of the weight sensor can be maintained higher.

  In addition to the effects of any one of the first to third aspects, the invention according to the fourth aspect can be simply configured by projecting the support body backward from the rear end of the grill.

  In addition to the effect of any one of Claims 1-3, when the said grilling net is mounted on the said saucer, invention of Claim 5 makes the said support body back from the rear end of the said saucer. Since it can be easily configured by protruding, the support protrudes rearward from the rear end of the grill net, and the support protrudes rearward from the rear end of the tray. Therefore, the degree of freedom in designing the grill is increased, and the design can be easily performed.

Further, the invention according to claim 1 is a grill capable of executing the clean mode, wherein the grill is baked when the user executes the clean mode in a state where the user accidentally stores the grill in the grill cabinet. This can prevent damage to the grill caused by the grille and improve the usability of the grill.

A storage 30 is provided. The grill 03 heats and cooks the food 34 placed on the grill 33 housed in the grill warehouse 30 by radiant heating or convection heating. A front opening (in / out port) 35 (see FIG. 4B) for taking in and out the food 34 of the grill cabinet 30 is closed by a grill door 31 provided in front of the gas stove 01 so as to be freely opened and closed. A saucer 37 is provided in the lower part of the grill warehouse 30, and a grill 33 as a placement part for placing the food 34 is placed on the saucer 37, and the food 34 is heated by the grill burner 32. It is configured as follows. In the present embodiment, the grill 33 is coated with a fluororesin or the like, and the food 34 such as fish is prevented from sticking to the grill 33.
An exhaust passage 40 for exhausting the combustion exhaust gas of the grill burner 32 to the outside of the machine is continuously provided on the rear side of the grill warehouse 30, and the combustion exhaust gas of the grill burner 32 is passed through the exhaust passage 40. The exhaust cover 42 is provided with a large number of small holes and is guided to an exhaust port 41 that is covered so as to prevent entry of foreign matter. The grill burner 32 is disposed at the upper part of the grill warehouse 30 and heats the upper surface of the cooked product 34 placed on the grill 33, and is disposed at the lower part of the grill warehouse 30 to heat the lower surface of the cooked product 34. And a pair of left and right lower burners 32b. In addition, in FIG. 4A, FIG. 4B, FIG. 5A, FIG. 5B, and FIGS. 7-9, description of the lower burner 32b is abbreviate | omitted.

  A grill setting input operation panel 06 (see FIG. 1) for inputting cooking settings by the grill 03 provided on the front surface of the gas stove 01, as shown in FIG. Timer increase / decrease switch 62 for setting the firing time), thermal power switch 63 for switching the heating power of the upper and lower fires, and a menu for firing to select a firing control corresponding to the corresponding fired product. A menu switch 64, an à la carte menu (to be described later), an a la carte menu switch 65 for selecting a firing control corresponding to the corresponding a la carte menu, a timer increase / decrease switch 62, a thermal power switch 63, a menu switch 64, an a la carte menu switch 65, etc. And a cancel switch 66 for canceling each input set by operating.

  Next, the case where the grill 03 is used will be described. By pressing the menu switch 64, the à la carte menu switch 65 or the timer increase / decrease switch 62 shown in FIG. 6 of the operation panel 06 provided on the front surface of the gas stove 01 with a finger, the cooking menu, the à la carte menu, the cooking time, etc. A setting input is performed, and then the ignition / extinguishing operation tool 61 (see FIG. 1) is pushed to perform an ignition input operation to ignite the grill 03. Thus, automatic cooking is performed by controlling the heating power, cooking time, and the like by the control unit 08 (see FIG. 3) so that the intended grill cooking is performed. When it is desired to stop the automatic cooking during the automatic cooking in the grill 03, the automatic cooking can be stopped by pressing the ignition / fire extinguishing operation tool 61 to extinguish the fire.

  The menus that can be switched by the menu switch 64 include “sake grilled”, “fillet”, and “dried fish”, and the a la carte menu switch 65 can be selected from three types: “clean mode”, “pizza”, and “baked rice ball”. It has become. In addition, when “pizza” is selected from the à la carte menu, an accessory metal cooking plate (not shown) is placed on the grill 33, and bread, pizza, etc. are placed on the cooking plate. It is recommended in the instruction manual that the food 34 is placed and cooked, and the user uses the accessory cooking plate as necessary and operates the à la carte menu switch 65 in accordance with this to prepare the à la carte menu cooking. I do. The clean mode will be described later in detail.

  The grill 03 measures a temperature rise rate (referred to as a temperature rise gradient) that changes in accordance with the difference in the state of placing the food 34 on the grill 33 in the initial stage after heating by the grill burner 32 is started. Cooking temperature detecting means 80 (see FIG. 3) is provided. The cooking temperature detecting means 80 detects the combustion exhaust gas temperature. The control unit 08 is based on the determination information calculation process for obtaining the temperature increase gradient based on the detection information of the cooking temperature detection means 80, and the information on the temperature increase gradient obtained in the determination information calculation process. The total heating time TT from the execution of the determination information calculation process to the end of the heating of the food 34 is obtained. The total heating time TT is obtained by applying a predetermined value or obtaining a value from a predetermined calculation formula according to the type of cooking menu and the placement state of the cooked product 34.

  When the temperature increase gradient is small, that is, when the temperature increase value at a predetermined time is small, it can be determined that a large cooked product 34 having a large heat capacity is placed on the grill 33 of the grill 03. Accordingly, the total heating time TT is calculated and set in a long time, and when the temperature increase gradient is large, that is, when the temperature increase value in a predetermined time is large, the grill 33 of the grill 03 has a small heat capacity with a small heat capacity. Therefore, the total heating time TT is calculated and set in a short eye according to the temperature increase gradient. The total heating time TT is calculated by substituting a value corresponding to the temperature increase gradient in advance or by substituting the value of the temperature increase gradient into a predetermined calculation formula.

  The elapsed time T1 from the time when heating by the grill burner 32 is started to the time when the total heating time TT is calculated and set is measured.

  Then, the remaining heating time T2 from the time when the total heating time TT is calculated and set until the heating of the cooked food 34 is finished is obtained as T2 = TT−T1, and T2 is calculated as a grill timer display (timer increase and decrease in FIG. 6). It is displayed on the upper side of the switch 62.

  After displaying T2 on the grill timer display unit, the remaining heating time T2 displayed on the grill timer display unit is counted down over time, and when the display on the grill timer display unit becomes zero, the grill burner 32 is displayed. Is extinguished, and automatic grill cooking control is terminated.

  Hereinafter, the configuration of the weight sensor 18 of this embodiment and the configuration of the intake passage 71 will be described.

  The grill door 31 is connected to a moving rail 38 (see FIGS. 2, 4A, 4B, 5A, and 5B) that constitutes a member that supports the tray 37 and the grill 33 placed thereon. Yes. The moving rail 38 is supported so as to be movable back and forth along a fixed rail 38a (not shown). When the user pulls out or pushes in the grill door 31 with the handle, the tray 37 placed on the moving rail 38 and the grill 33 placed thereon move back and forth. It is configured.

  4A, 4B, 5A, 5B, and 7 to 9, a weight sensor 18 having a measuring rod 19 is disposed at the rear (back side) of the grill cabinet 30 after the grill cabinet 30. It is attached to the rear of the wall 30a, and is configured so that the weight sensor 18 detects a load applied from above the measuring rod 19.

  In the first embodiment, as shown in FIGS. 4A and 4B, the rear support provided at the rear end of the grille 33 among the front support legs 33a and the rear support legs 33b when the grille 33 is placed on the tray 37. The support body 25 protrudes rearward from the leg 33b. The rear wall 30a of the grill cabinet 30 is provided with a communication port 50 through which the support 25 is inserted, and when the grill door 31 is located at a closed position that closes the front opening (in / out port) 35, a tray 37 is provided. And the grill 33 are located in a predetermined storage position, and the support 25 is inserted into the communication port 50 and placed on the measuring rod 19. At this time, the load applied from the measuring rod 19 is weighted. The sensor 18 is configured to detect.

  Although not shown in FIG. 4A, as described above, when the support 25 is inserted on the communication port 50 and placed on the measuring rod 19, it is placed on the tray 37. The lower end of the support leg 33 b is slightly lifted from the tray 37. Therefore, the weight sensor 18 has the rear end of the support 25 on the measuring rod 19 in accordance with the moment acting on the grill 33 with the position where the lower end of the front support leg 33a of the grill 33 abuts on the tray 37 as a fulcrum. The applied load will be measured.

  Further, when the grill door 31 moves from the closed position that closes the front opening (in / out port) 35 to a slightly opened position, the tray 37 and the grill 33 are located at a position slightly pulled out from the predetermined storage position. Although the support body 25 is inserted into the communication port 50 and protrudes to the rear side of the rear wall 30a, the support body 25 is not placed on the measurement rod 19, and a load is applied from above the measurement rod 19 at this time. The load which is not applied and the weight sensor 18 measures becomes a value close to zero. Of course, the support body 25 is not placed on the measuring rod 19 even when the grill door 31 is located at the open position for opening the slot, and no load is applied from above the measuring rod 19 at this time. The load measured by the weight sensor 18 is a value close to zero.

  Therefore, when the load measured by the weight sensor 18 is equal to or less than the first set value set to a value slightly larger than zero, a notification that the grill door 31 is in the open position or the grill door 31 is not in the closed position. By performing the above, it is possible to prevent a cooking error when the user mistakenly performs cooking by the grill 03 with the grill door 31 half-opened or fully opened.

  As described above, the weight sensor 18 is arranged at the rear of the grill cabinet 30, so that the load corresponding to the weight of the food 34 can be measured by the weight sensor 18, and the grill door 31 is in the closed position. Therefore, it is possible to prevent a cooking error when cooking is performed in a state where the grill door 31 is not in the closed position. However, a weight sensor is provided by an increase in ambient temperature due to combustion of the grill burner 32. When the temperature of the weight 18 rises, the weight measurement by the weight sensor 18 may not be performed accurately. Therefore, in order to suppress the temperature rise of the weight sensor 18, the following is configured.

  As shown in FIGS. 4A and 4B, a sensor cover 51 that covers the left and right sides and the upper side of the portion of the support body 25 that protrudes from the communication port 50 into the housing 12 and covers the left and right sides and the upper side of the weight sensor 18. The lower part of the sensor cover 51 near the weight sensor 18 is an open portion 52 that is not covered by the sensor cover 51. 4A and 4B, the sensor cover 51 is described as a portion covering the left and right sides of a portion of the support 25 that protrudes from the communication port 50 into the housing 12 and a portion covering the left and right sides of the weight sensor 18. Is omitted.

  Further, cooking exhaust generated by heating due to the combustion of the grill burner 32 when the grill burner 32 burns flows through the exhaust passage 40 toward the upper exhaust port 41 by the draft, and is discharged from the exhaust port 41. At this time, The lower portion in the vicinity of the rear wall 30a in the grill 30 has a negative pressure due to the draft, and the communication port 50 is formed in the negative pressure portion. Air in the housing 12 in which the grill cabinet 30 is housed flows into the grill cabinet 30 via 50.

  In this case, as described above, the sensor cover 51 that covers the left and right sides and the upper side of the portion of the support body 25 that protrudes from the communication port 50 into the housing 12 and covers the left and right sides and the upper side of the weight sensor 18 is provided. The lower portion of the sensor cover 51 near the weight sensor 18 is an open portion 52 that is not covered by the sensor cover 51. The sensor cover 51 passes through the periphery of the weight sensor 18 from the open portion 52 inside the housing 12. Thus, the intake flow path 71 is formed in the region reaching the communication port 50.

  That is, an air intake portion 60 through which air that has flowed into the housing 12 from the outside of the housing 12 flows into the intake flow passage 71 as intake air is formed by the open portion 52 in the vicinity of the weight sensor 18, as shown in FIG. Furthermore, during combustion of the grill burner 32, the intake air that has flowed from the intake portion 60 into the intake passage 71 flows toward the communication port 50, and then the intake air flows into the exhaust passage 40 through the communication port 50. The weight sensor 18 and the support body 25 are cooled by the intake air. In FIG. 7, arrow A represents the flow of intake air.

  Further, during the combustion of the grill burner 32, an air flow is generated so that the air in the housing 12 flows into the grill warehouse 30 via the communication port 50. 50 is prevented from flowing out of the grill warehouse 30, and the weight sensor 18 is exposed to a high temperature and the measurement accuracy by the weight sensor 18 is prevented from being lowered.

  In addition, as a convenient function, the grill 03 has a cleaning mode in which the grill 33 and the cooked food 34 are not stored in the grill chamber 30 and are heated by combustion of the grill burner 32 in order to burn out the oil adhering to the grill chamber 30. It can be executed.

  In order to execute the cleaning mode, only the tray 37 is placed on the moving rail 38, the grill net 33 is not placed on the tray 37, and, of course, the cooked product 34 is not placed on the grill door. 31 is closed and the tray 37 is stored, the a la carte menu switch 65 of the operation panel 06 shown in FIG. 6 is operated to select the clean mode, and then the ignition / fire extinguishing operation tool 61 (see FIG. 1) is pressed. Then, an ignition input operation is performed to ignite the grill 03.

  However, if the load measured by the weight sensor 18 is greater than or equal to the second set value when attempting to execute the above-described clean mode, the ignition / fire extinguishing operation tool 61 is selected after operating the a la carte menu switch 65 to select the clean mode. Even if the ignition input operation is performed by pressing (see FIG. 1) to ignite the grill 03, the grill burner 32 does not start the combustion and does not execute the clean mode. It is configured to prevent damage due to overheating of the grill 33 that is stored inside and executes the clean mode and is baked without placing the food 34 on the grill 33.

In the first embodiment in which the support body 25 protrudes rearward from the rear support leg 33b provided at the rear end of the grill 33 as shown in FIGS. 4A and 4B, the second set value is the above-described first setting value. It is set to the same value as the set value of 1, and the clean mode is not executed when the grill 33 is in the storage position.

  In the first embodiment described above, this is equivalent to the configuration in which the clean mode is executed only when the grill 33 is not in the storage position. However, when the clean mode is executed, the grill door 31 is used. When the load is not in the closed position, the load measured by the weight sensor 18 is less than the second set value, and it is considered that the grill door 31 is in an incompletely closed state and the clean mode is executed. The second embodiment described below is also preferable.
