Description
[Technical field]
[0001] One aspect of the present invention relates to a bag-type cooking device. [Background technology]
[0002] Conventionally, one of the cooking systems for heating and cooking objects to be cooked is a bag-type cooking system described in Patent Document 1. This bag-type cooking system is configured to include a bag-type cooking device in which the objects to be cooked are stored, and a control device connected to the cooking device. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2017-189451 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, although the conventional cooking system described in the above Patent Document 1 discloses a configuration including a temperature sensor, the temperature sensor is not placed in a position that takes into consideration the size and storage position of the food to be cooked stored in the bag. Therefore, depending on the storage position of the food to be cooked stored in the bag, for example, the temperature sensor may directly touch the food to be cooked, which may affect the temperature detection result by the temperature sensor and make it impossible to detect the temperature accurately. In this case, there is a risk that temperature abnormalities may not be detected properly.
[0005] In addition, the cooking system described in Patent Document 1 is configured to have a gusset at the bottom of the bag body, and since the food to be cooked is often located in the gusseted part of the bottom, a conductive material is provided at the bottom. However, even in this case, it cannot be said that the temperature sensor is placed in a position that takes into consideration the size and storage position of the food to be cooked, as described above, and the configuration cannot be said to be capable of detecting the temperature accurately. [Means for solving the problem]
[0006] The present invention provides the following means to solve any of the above problems.
[0007] A bag-type cooking device according to one aspect of the present invention is a bag-type cooking device capable of storing and cooking an object to be cooked therein, a first laminate sheet and a second laminate sheet, each including a heat source sheet formed including a heating element that generates heat when electricity is applied and a heat insulating sheet arranged on the outside of the heat source sheet and made of a heat insulating material, are arranged to face each other, and their peripheral portions are connected to each other, forming a bag-shaped main body having an opening that can be opened and closed freely; a connection portion electrically connected to the heating element and exposed to an outside of the main body; a power supply unit electrically connected to the connection unit; and a temperature sensor arranged inside the heat insulating sheet and near the periphery of the main body portion.
[0008] According to the bag-type cooking device as described above, the temperature sensor is positioned at a certain distance from the object to be heated, so that the temperature detection results by the temperature sensor are not affected by the object to be heated, and the temperature inside the main body can be properly detected.
[0009] In the above bag-type cooking device, preferably, the heat source sheet of each of the first laminated sheet and the second laminated sheet is disposed on the innermost side of the main body portion.
[0010] According to the bag-type cooking device as described above, heat can be efficiently transferred from the heating element to the food to be cooked. Also, by not providing a heat conductive sheet on the inside of the heat source sheet, manufacturing costs can be reduced.
[0011] In the bag-type cooking device, preferably, the temperature sensor is A first temperature sensor; and a second temperature sensor disposed spaced apart from the first temperature sensor.
[0012] According to the above-mentioned bag-type cooking device, each temperature sensor is disposed at a certain distance from the food to be cooked, so that the temperature inside the main body can be detected more appropriately. Furthermore, by providing multiple temperature sensors, even if the temperature inside the main body varies, the temperature can be detected appropriately. Furthermore, even if one temperature sensor breaks down or shows an abnormal value, the other temperature sensor can easily detect the appropriate temperature.
[0013] In the above-mentioned bag-type cooking device, preferably, the main body is rectangular in a plan view, the first temperature sensor is disposed near a first vertex of the rectangular body portion; The second temperature sensor is disposed near a second vertex of the rectangular body portion that is different from the first vertex.
[0014] According to the bag-type cooking device as described above, by arranging each temperature sensor at a position appropriately separated from the food to be cooked, it becomes possible to more appropriately detect the temperature inside the main body.
[0015] In the bag-type cooking device, preferably, the first temperature sensor is disposed on the first laminated sheet, The second temperature sensor is disposed in the second laminate sheet.
[0016] According to the bag-type cooking device described above, the temperature sensors are positioned at an appropriate distance from the food to be cooked, making it possible to more accurately detect the temperature inside the main body. Also, since the temperature can be detected from both sides of the bag-type main body, it is possible to quickly detect an overheated state of the main body.
[0017] In the above bag-type cooking device, preferably, the main body portion is A bag-shaped storage area formed on the side where the opening is provided and capable of storing the food to be cooked; A non-storage area in which the object to be cooked cannot be stored is formed on the opposite side to the side where the opening is provided, The temperature sensor is disposed in the outer storage area.
[0018] According to the bag-type cooking device described above, the temperature sensor arranged in the outside storage area is arranged at a position sufficiently far away from the food to be cooked, so that the temperature inside the main body can be detected without being affected by the food to be cooked. Also, it is easy to detect the temperature inside the main body without providing multiple temperature sensors.
[0019] In the above bag-type cooking device, preferably, at least one of the first temperature sensor and the second temperature sensor is disposed near an edge portion on the side opposite to the side on which the opening is provided.
[0020] With the above-described bag-type cooking device, the temperature can be detected without being affected by the outside air temperature, compared to a configuration in which a temperature sensor is installed near an opening that is easily exposed to outside air, and therefore the temperature inside the main body can be detected more accurately.
[0021] In the bag-type cooking device, preferably, the main body has a gusset portion, The temperature sensor is disposed at a position spaced apart from the gusset portion.
[0022] According to the bag-type cooking device described above, even if the main body has a gusseted portion, the temperature sensor can be disposed at a position away from the food to be cooked, so that the temperature detection result by the temperature sensor is less likely to be affected by the food to be cooked. This allows the temperature sensor to properly detect the temperature inside the main body.
[0023] In the above-mentioned bag-type cooking device, preferably, the main body has a bottom gusset portion formed on the side opposite to the side on which the opening is provided, The temperature sensor is disposed proximate the opening.
[0024] According to the bag-type cooking device described above, even if the main body has a gusseted portion, the temperature sensor can be disposed at a position away from the food to be cooked, so that the temperature detection result by the temperature sensor is less likely to be affected by the food to be cooked. This allows the temperature sensor to properly detect the temperature inside the main body.
[0025] Further, a bag-type cooking device according to one aspect of the present invention is a bag-type cooking device capable of storing and cooking an object to be cooked therein, a first laminate sheet and a second laminate sheet, each including a heat source sheet formed including a heating element that generates heat when electricity is applied and a heat insulating sheet arranged on the outside of the heat source sheet and formed of a heat insulating material, are arranged to face each other and connected to each other without having a gusset portion, and a bag-shaped main body portion having an opening that can be opened and closed freely; a connection portion electrically connected to the heating element and exposed to an outside of the main body; and a power supply unit electrically connected to the connection unit.
[0026] According to the bag-type cooking device as described above, since the device does not have a gusset, heat is easily transferred to the food to be cooked. Therefore, the food to be cooked can be cooked without heating the inside of the main body to an unnecessarily high temperature.
[0027] In the above bag-type cooking device, preferably, the heat source sheet of each of the first laminated sheet and the second laminated sheet is disposed on the innermost side of the main body portion.
[0028] According to the above-described bag-type cooking device, heat can be more easily transferred to the food to be cooked. [Brief description of the drawings]

[0030] A bag-type cooking device according to one embodiment of the present invention will be described in detail below with reference to the drawings. However, the embodiment described below is merely one example of the present invention, and is not intended to limit the technical scope of the present invention. In addition, the same components are given the same reference numerals in each drawing, and their description may be omitted.
[0031] In this specification, for convenience of explanation, the upper side and the lower side are sometimes described corresponding to the top and bottom of the drawings, but the bag-type cooking device of the embodiment may be arranged with the main body lying on a table or arranged upside down. Therefore, the top, bottom and bottom may be reversed. Even in this case, the side where the opening is formed is generally referred to as the upper side, although there are exceptions. The upper side may also be referred to as one side and the lower side as the other side, etc.
[0032] [Overall configuration of bag-type cooking device 1] The figure shows the external configuration of the bag-type cooking device 1 of this embodiment. As shown in Fig. 1, the bag-type cooking device 1 includes a main body 2, a connection part 41, cables 42 and 44, a power supply part 43, and a power plug 45.
[0033] [Main body 2] As shown in FIG. 1, the main body 2 has an opening 2a that can be opened and closed, and is formed in a bag shape without a gusset. The main body 2 is formed in a bag shape without a gusset by connecting the peripheral parts except for the opening 2a with two laminated sheets arranged to face each other. The opening 2a is provided with a fastener having a grip part 2b that can be operated to open and close the opening 2a. A user can open and close the opening 2a by gripping and sliding the grip part 2b. The main body 2 of this embodiment is formed in a square shape with four sides of 24 cm in a plan view. The size of each part in this embodiment is an example of the size when the main body 2 is a square with four sides of 24 cm.
[0034] Fig. 2 is a diagram showing an example of the configuration of the laminated sheet 21 that constitutes the main body 2 of the bag-type cooking device 1. Fig. 3 is a diagram showing the main body 2 of the bag-type cooking device 1 in an opened state for ease of explanation.
[0035] [Laminated sheet 21] As shown in Fig. 2, each laminate sheet 21 is configured by sequentially laminating a heat source sheet 22, a heat insulating sheet 23, and an exterior cloth 24. Each laminate sheet 21 is formed in a rectangular shape, but is not limited to this. In the main body 2, the heat source sheet 22 of the laminate sheet 21 is disposed on the innermost side, and the exterior cloth 24 is disposed on the outermost side. That is, in the two laminate sheets 21a and 21b (see Fig. 3) disposed opposite each other, the heat source sheets 22 are disposed so as to face each other inside the main body 2.
[0036] As shown in FIG. 3, the laminated sheet 21a is formed with the outer edges 34a, 34b, 34c, and 34d, which are the sides that form a rectangle, as its periphery. Similarly, the laminated sheet 21a is formed with the outer edges 34a, 34e, 34f, and 34g, which are the sides that form a rectangle, as its periphery. In the laminated sheets 21a and 21b, the outer edge 34a is connected, and the outer edges 34c and 34f, and 34d and 34g are connected to each other. The outer edges 34b and 34e are provided with a fastener so as to be openable and closable and connected to each other to form the opening 2a. Various methods such as sewing or bonding may be used as the connection method. In addition, even if the laminated sheets 21a and 21b are integrally formed, this specification includes the case where they are connected to each other.
[0037] [Heat source sheet 22] The heat source sheet 22 includes a sheet-like portion 22a having thermal conductivity and a heating element 31 that generates heat when electricity is applied. The sheet-like portion 22a is made of a polyimide resin (PI film) having thermal conductivity formed in a thin sheet (film). The heating element 31 is made of wires made of iron-chromium-aluminum containing iron (Fe), chromium (Cr), and aluminum (Al), which is conductive and generates heat when electricity is applied, and is arranged so as to be widely spread over the area of the heat source sheet 22 except for the vicinity of the periphery (see FIG. 3).
[0038] [Thermal insulation sheet 23] The heat insulating sheet 23 is disposed on the outer side of the heat source sheet 22 in the main body 2 so as to cover the entire heat source sheet 22, and is made of a material such as melamine resin having thermal insulation properties. In addition to thermal insulation properties, the heat insulating sheet 23 preferably has flame retardancy, heat resistance, and water absorbency.
[0039] [Exterior cloth 24] The exterior cloth 24 is disposed on the outside of the heat insulating sheet 23 in the main body 2, and is arranged to cover the entire heat insulating sheet 23 so as to be the outermost part of the main body 2, and is formed from a fibrous material such as polyester. Since the exterior cloth 24 is located at the outermost part of the main body 2, it serves as the exterior of the main body 2. For this reason, the exterior cloth 24 is preferably formed from a fibrous (cloth-like) material that feels good to the touch for the user.
[0040] The materials used to form the heat source sheet 22, the heat insulating sheet 23, and the exterior cloth 24 are merely examples, and other materials capable of realizing the functions of each component may be used.
[0041] [Temperature sensors 33a, 33b] The temperature sensors 33a and 33b can detect the surrounding temperature, and are disposed inside the heat insulating sheet 23 in the main body 2 and near the periphery of the main body 2. As a result, the temperature sensors 33a and 33b detect the temperature inside the main body 2. The temperature sensors 33a and 33b are disposed at positions away from each other so as not to be close to each other. The temperature sensor 33a is disposed near the edge of the bottom side opposite to the opening 2a, and the temperature sensor 33b is disposed near the opening 2a. More specifically, the temperature sensors 33a and 33b are disposed at positions 10 mm to 30 mm away from the periphery of the laminated sheet 21 of the main body 2, and preferably at positions 15 mm to 25 mm away from the periphery of the laminated sheet 21. The temperature sensors 33a and 33b are preferably disposed at a distance of 100 mm or more from each other, and more preferably at a distance of 150 mm or more from each other.
[0042] For example, temperature sensor 33a is disposed near a first vertex 34h of a rectangle in laminate sheet 21a. Temperature sensor 33b is disposed near a second vertex 34i of a rectangle in laminate sheet 21b. The first vertex and the second vertex are diagonally opposite each other when main body 2 is viewed in a plan view. Temperature sensors 33a and 33b are disposed at positions about 20 mm from the periphery of laminate sheet 21.
[0043] One of the purposes of arranging the two temperature sensors 33a and 33b in the main body 2 is to properly detect the temperature inside the main body 2 using one temperature sensor when a malfunction such as a breakdown occurs in the other temperature sensor. Another purpose of arranging the two temperature sensors 33a and 33b is to more properly detect the temperature inside the main body 2 based on the detection results of the multiple temperature sensors. However, the main body 2 may be configured to have only one of the temperature sensors 33a and 33b.
[0044] Moreover, the periphery of the main body 2 refers to the periphery on the inside of the main body 2, and refers to the position where the laminated sheets 21 are connected. For example, if the laminated sheets 21 are connected by sewing, the sewing position is regarded as the periphery, and the temperature sensors 33a and 33b are disposed at a position 10 mm to 30 mm from this position.
[0045] [Terminal section 32a~32f] The heating element 31 of the heat source sheet 22 is connected to the terminal portions 32a to 32f. The terminal portions 32a to 32f are terminals for supplying power to the heating element 31, and are electrically connected to the connection portion 41. The terminal portions 32a and 32d are located opposite each other inside the main body portion 2, and are electrically connected to each other. Similarly, the terminal portions 32b and 32e, and 32c and 32f are located opposite each other inside the main body portion 2, and are electrically connected to each other. The terminal portions 32a and 32d are either the positive electrode or the negative electrode, and the terminal portions 32b, 32c, 32e, and 32f are either the positive electrode or the negative electrode, and a current flows between the terminals via the heating element 31.
[0046] [Connection 41] The connection portion 41 is electrically connected to the heating element 31 via the terminal portions 32a to 32f, and is formed so as to be exposed to the outside of the main body portion 2. The connection portion 41 is electrically connected to a power supply portion 43 via a cable .
[0047] [Power supply section 43] The power supply unit 43 is electrically connected to the connection unit 41 via a cable 42 including conductive wiring, and supplies power to the main body 2. The power supply unit 43 can be connected to a household power terminal via a cable 44 and a power plug 45, and is supplied with power of 100V AC from the household power terminal.
[0048] The power supply unit 43 includes a transformer that converts the 100V AC voltage supplied from the household power terminal into a predetermined DC voltage. The power supply unit 43 also functions as a control unit that controls the main body unit 2 and an operation unit that accepts operation inputs from the user. It also functions as a
[0049] As shown in FIG. 1, the power supply unit 43 includes a display unit 43a and operation buttons 43b to 43e.
[0050] The display unit 43a visually displays to the user the settings and status of the bag-type cooking device 1. For example, the display unit 43a displays the set temperature of the bag-type cooking device 1, the set cooking time, the temperature inside the main body 2, the time remaining until the end of cooking, or the elapsed time from the start of the setting.
[0051] Operation buttons 43b-43e are operated by a user. Power supply unit 43 changes various settings of bag-type cooking device 1, adjusts the power supplied to main body 2, and switches the display content of display unit 43a in response to the user's operation of operation buttons 43b-43e.
[0052] [Variations] The bag-type cooking device 1 of the present invention is not limited to the configuration of the above embodiment, and various modifications are possible without departing from the spirit of the invention. Examples of such modifications include the following configurations.
[0053] [Variation 1] FIG. 4 is a diagram showing an example of the configuration of the main body 200 of the bag-type cooking device according to the first modification. As shown in FIG. 4, the main body 200 of this modification has a stitched portion 35 formed parallel to the outer edges 34d and 34g on the upper side of the outer edges 34d and 34g, which are the lower side of the drawing. The stitched portion 35 divides the internal area of the main body 2 into a bag-shaped storage area 35a that can store the food to be cooked and is formed on the side where the opening 2a is provided from the stitched portion 35, and an outside storage area 35b that cannot store the food to be cooked and is formed on the opposite side to the side where the opening 2a is provided. The main body 200 of this modification has a temperature sensor 33c arranged in the outside storage area 35b. In this modification, the outside storage area 35b is a dedicated area for temperature inspection by the temperature sensor 33c.
[0054] More specifically, the temperature sensor 33c is preferably disposed near the storage area 35a in order to detect the temperature inside the storage area 35a in which the food to be cooked is stored. The temperature sensor 33c is disposed, for example, within 20 mm from the storage area 35a.
[0055] According to the bag-type cooking device having the main body 200 of this modified example, the temperature inside the main body 2 can be detected while suppressing the influence of the temperature of the food to be cooked, while having only one temperature sensor. However, considering the possibility of the temperature sensor 33c failing, it is more preferable to have two or more temperature sensors. In this case, the two or more temperature sensors are arranged in the outside storage area 35b, similar to the temperature sensor 33c.
[0056] The structure for separating the storage area 35a and the non-storage area 35b is not limited to the sewn portion 35 formed by sewing, and may be replaced with another structure.
[0057] Further, a configuration other than the temperature sensor 33c may be disposed in the outside storage area 35b.
[0058] [Variation 2] Fig. 5 is a diagram showing an example of the configuration of main body 201 of a bag-type cooking device according to a second modified example. As shown in Fig. 5, main body 201 of this modified example is circular rather than rectangular in plan view, and has an opening 201a formed in an arc shape. Main body 201 of this modified example is a circle with a diameter of 24 cm in plan view, and the size of each part in this modified example is an example of the case where main body 201 has such a size. Opening 201a extends to the portion indicated by the dotted line in Fig. 5, and is formed to be openable and closable by a zipper as in the embodiment.
[0059] The main body 201 of this modification includes temperature sensors 33d, 33e, and 33f. These temperature sensors 33d, 33e, and 33f are arranged near the inner periphery of the main body 201, similar to the temperature sensors 33a and 33b in the main body 2 of the embodiment. Specifically, the temperature sensors 33d and 33e are arranged near the lateral periphery, and the temperature sensor 33f is arranged near the edge of the bottom, away from the opening 201a. As in the embodiment, the specific positions at which the temperature sensors 33d, 33e, and 33f are arranged are preferably 10 mm to 30 mm from the periphery of the main body 201, more preferably 15 mm to 25 mm from the periphery of the main body 201, for example, about 20 mm from the periphery of the main body 201. In addition, these temperature sensors 33d, 33e, and 33f are arranged 100 mm or more away from each other, more preferably 150 mm or more away.
[0060] The configuration of the main body 201 may be various shapes other than a circle, such as an ellipse, a trapezoid, or other polygons.
[0061] [Variation 3] Fig. 6 is a diagram showing an example of the configuration of main body parts 202-205 of a bag-type cooking device having gusset parts 36a-36d, which is a third modified example. In a bag-type cooking device including main body parts 202-205 having these gusset parts 36a-36d, the food to be cooked is often located in the gusset parts 36a-36d or in a location close to the gusset parts 36a-36d, so the temperature sensor is arranged at a location away from the gusset parts 36a-36d. This will be specifically described below.
[0062] The main body 202 of this modified example shown in FIG. 6(a) has a gusset portion 36a in a rectangular bottom portion opposite to the side where the opening 202a is formed. In this specification, a gusset portion such as the gusset portion 36a formed in the bottom portion may be called a bottom gusset portion. In the main body 202 of such a bag-type cooking device, the food to be cooked is accommodated in the vicinity of the bottom portion where the gusset portion 36a, which is the bottom gusset portion, is formed. Therefore, the temperature sensors 33g and 33h are arranged in the vicinity of the opening 202a that is configured to be openable and closable by a fastener so as not to come into contact with the food to be cooked. The temperature sensors 33g and 33h are arranged at a position 10 mm or more and 30 mm or less from the opening 202a, which is one of the peripheries of the main body 202. Also, the temperature sensors 33g and 33h are preferably arranged so as to be separated from each other by 100 mm or more. The main body 202 may be arranged to have only one of the temperature sensors 33g and 33h. In addition, if the opening 202a is not a zipper but has another structure such as a structure that closes by folding, the position where the temperature sensor is disposed may be different from the above. This also applies to the following modified examples.
[0063] The main body 203 of this modified example shown in Fig. 6(b) has a gusseted portion 36b at the bottom, which is the side opposite to the side where the opening 203a is formed. In the main body 203 of such a bag-type cooking device, the food to be cooked is accommodated near the bottom where the gusseted portion 36b is formed. Therefore, the temperature sensor 33i is disposed near the opening 203a so as not to come into contact with the food to be cooked. For example, the temperature sensor 33i is disposed at a position 10 mm to 30 mm away from the opening 203a, which is one of the peripheries of the main body 203.
[0064] The main body 204 of this modified example shown in FIG. 6(c) has an opening 204a formed in a side portion, and a gusset portion 36c in a side portion opposite to the side where the opening 204a is formed. In the main body 204 of such a bag-type cooking device, the food to be cooked is accommodated in the vicinity of the side portion where the gusset portion 36c is formed. Therefore, the temperature sensor 33j is arranged in the vicinity of the upper edge portion different from the side portion where the opening 204a and the gusset portion 36c are formed so as not to come into contact with the food to be cooked. For example, the temperature sensor 33j is arranged at a position 10 mm to 30 mm from the upper edge portion, which is one of the peripheries of the main body 203.
[0065] The main body 205 of this modified example shown in Fig. 6(d) has a gusseted portion 36d at the top where the opening 205a is formed. In the main body 205 of such a bag-type cooking device, the food to be cooked is accommodated near the top where the gusseted portion 36d is formed. Therefore, the temperature sensor 33k is arranged near the bottom, which is the opposite side to the top where the opening 205a is formed, so as not to come into contact with the food to be cooked. For example, the temperature sensor 33k is arranged at a position 10 mm to 30 mm away from the bottom, which is one of the peripheries of the main body 205.
[0066] When the main body has a gusset as in the above modified example, it is preferable to place the temperature sensor at a position away from the gusset.
[0067] [Variation 4] 7 is a diagram showing an example of the configuration of main body 206 of a bag-type cooking device according to a fourth modified example. In this modified example, laminated sheet 21c includes heat source sheet 22, insulating sheet 23, and exterior cloth 24, as well as heat conductive sheet 25. Heat conductive sheet 25 is disposed on the innermost side of main body 206, closer to the inside than heat source sheet 22.
[0068] The thermally conductive sheet 25 conducts heat generated in the heat source sheet 22 while diffusing the heat inside the main body 206. The thermally conductive sheet 25 is made of a polyimide resin (PI film) having thermal conductivity formed in a thin sheet (film).
[0069] [Other variations] The bag-type cooking device 1 is not limited to the configuration having the main bodies 200 to 206 as described above, and various modified examples may be adopted without departing from the spirit of the invention.
[0070] For example, the bag-type cooking device 1 may be configured not to have a temperature sensor at the position of the embodiment and modified example, and the main body 2 may be configured not to have a gusset portion. In this case, the laminated sheets 21a and 21b are arranged to face each other and are connected to each other without having a gusset portion. By adopting such a configuration without a gusset portion, it is possible to make it possible to easily transfer heat to the food to be cooked.
[0071] The opening 2a does not necessarily have to be configured so as to be freely opened and closed by a fastener, but may be configured so as to be freely opened and closed by magnetic force, a hook-and-loop fastener, a folded shape, or any other physical structure.
[0072] The main body 2 may be configured not to be connected to a household power terminal, but to be powered by a rechargeable storage battery such as a lithium ion battery.
[0073] A humidity sensor may be disposed inside the main body 2 in addition to the temperature sensor. In this case, the humidity sensor may be disposed in the same position as the temperature sensor. Alternatively, the humidity sensor may be disposed in a position different from the temperature sensor. Alternatively, a temperature and humidity sensor in which the temperature sensor and the humidity sensor are integrated may be used.
[0074] [Summary of the embodiment and modifications] As described above, the bag-type cooking device 1 of the embodiment and the modified example is a bag-type cooking device 1 capable of storing and cooking an object to be cooked inside. The bag-type cooking device 1 has a main body 2, a connection part 41, a power supply part 43, and temperature sensors 33a and 33b. The main body 2 has two laminated sheets 21, namely, laminated sheets 21a and 21b. Each laminated sheet 21 includes a heat source sheet 22 formed including a heating element 31 that generates heat when electricity is applied, and a heat insulating sheet 23 disposed on the outside of the heat source sheet 22 and formed of a heat insulating material. The laminated sheets 21 are disposed to face each other, and the peripheral parts are connected to each other. In this manner, the laminated sheets 21a and 21b form the main body 2 formed in a bag shape having an opening 2a that can be opened and closed. The connection part 41 is electrically connected to the heating element 31 and exposed to the outside of the main body 2. The power supply part 43 is electrically connected to the connection part 41. The temperature sensors 33a and 33b are each disposed inside the heat insulating sheet 23 and in the vicinity of the periphery of the main body 2. It is also possible to provide only one of the temperature sensors 33a and 33b.
[0075] According to this type of bag-type cooking device 1, the temperature sensors 33a and 33b (or either one of them) are positioned at a position some distance away from the object to be heated, so that the temperature detection results by the temperature sensors 33a and 33b are not affected by the object to be heated, and the temperature inside the main body 2 can be properly detected.
[0076] In the bag-type cooking device 1 of the embodiment and the modified example, the heat source sheet 22 of each of the laminated sheets 21a and 21b is disposed on the innermost side of the main body portion 2.
[0077] Such a bag-type cooking device 1 can efficiently transfer heat from the heating element 31 to the food to be cooked. Furthermore, by not providing a thermally conductive sheet inside the heat source sheet 22, manufacturing costs can be reduced.
[0078] The bag-type cooking device 1 of the embodiment and the modified example includes temperature sensors 33a and 33b, with temperature sensor 33b being disposed at a position spaced apart from temperature sensor 33a.
[0079] According to such a bag-type cooking device 1, the temperature sensors 33a and 33b are disposed at positions some distance away from the food to be cooked, so that the temperature inside the main body 2 can be detected more appropriately. Furthermore, by providing multiple temperature sensors 33a and 33b, the temperature can be detected appropriately even if there is variation in the temperature inside the main body 2. Furthermore, even if one of the temperature sensors 33a and 33b breaks down or indicates an abnormal value, the other temperature sensor 33a or 33b can detect the appropriate temperature.
[0080] In the above description, the size of the main body 2 is, for example, a square with four sides of 24 cm in plan view. The distance between the temperature sensors 33a and 33b is preferably 100 mm or more.
[0081] In the bag-type cooking device 1 of the embodiment and modified example, the main body 2 is rectangular in a planar view, the temperature sensor 33a is positioned near a first vertex 34h of the rectangular main body 2, and the temperature sensor 33b is positioned near a second vertex 34i of the rectangular main body 2.
[0082] According to such a bag-type cooking device 1, by arranging each temperature sensor at a position appropriately separated from the food to be cooked, it becomes possible to more appropriately detect the temperature inside the main body.
[0083] In the bag-type cooking device 1 of the embodiment and the modified example, the temperature sensor 33a is disposed on one laminated sheet 21a, and the temperature sensor 33b is disposed on the other laminated sheet 21b.
[0084] According to such a bag-type cooking device 1, the temperature sensors 33a and 33b are arranged at positions appropriately separated from the food to be cooked, which makes it possible to more appropriately detect the temperature inside the main body 2. Also, since the temperature can be detected from both side surfaces of the bag-type main body 2, an overheated state of the main body 2 can be quickly detected.
[0085] In the modified bag-type cooking device 1, the main body 2 has a storage area 35a and a non-storage area 35b. The storage area 35a is an area formed on the side where the opening 2a is provided and capable of storing food items. The non-storage area 35b is an area formed on the opposite side to the side where the opening 2a is provided and unable to store food items. The temperature sensor 33c is disposed in the non-storage area 35b.
[0086] According to this bag-type cooking device 1, the temperature sensor 33c arranged in the outer storage area 35b is arranged at a position sufficiently far away from the food to be cooked, so that the temperature inside the main body 2 can be detected without being affected by the food to be cooked. Also, the temperature inside the main body 2 can be easily detected without providing multiple temperature sensors.
[0087] In the bag-type cooking device 1 of the embodiment and the modified example, at least one of the temperature sensors 33a and 33b is disposed near the edge on the side opposite to the side on which the opening 2a is provided.
[0088] With this type of bag-type cooking device 1, the temperature can be detected without being affected by the outside air temperature, compared to a configuration in which a temperature sensor is only provided near the opening 2a that is easily exposed to the outside air, and therefore the temperature inside the main body 2 can be detected more appropriately.
[0089] In the above case, the other of the temperature sensors 33a and 33b may be disposed near the opening 2a.
[0090] In the modified bag-type cooking device 1, the main bodies 202-205 have gusset portions 36a-36d, and the temperature sensor is disposed at a position spaced apart from the gusset portions 36a-36d.
[0091] According to this bag-type cooking device 1, even if the main bodies 202-205 have the gussets 36a-36d, the temperature sensors 33h-33k can be disposed at positions away from the food to be cooked, so that the temperature detection results of the temperature sensors 33h-33k are less likely to be affected by the food to be cooked. This allows the temperature sensors 33h-33k to properly detect the temperature inside the main bodies 202-205.
[0092] In the modified bag-type cooking device 1, for example, the main body 202 has a gusset portion 36a which serves as a bottom gusset portion formed on the side opposite to the side on which the opening 202a is provided, and the temperature sensors 33g and 33h are positioned near the opening 202a.
[0093] According to this bag-type cooking device 1, even if the main body 202 has the gusset portion 36a, the temperature sensors 33g and 33h can be disposed at positions away from the food to be cooked, so that the temperature detection results by the temperature sensors 33g and 33h are less likely to be affected by the food to be cooked. This allows the temperature sensors 33g and 33h to properly detect the temperature inside the main body 202.
[0094] The bag-type cooking device 1 of the present embodiment and the modified example is a bag-type cooking device 1 capable of storing and cooking an object to be cooked inside. The bag-type cooking device 1 has a main body 2, a connection part 41, and a power supply part 43. The main body 2 has two laminated sheets 21, namely, laminated sheets 21a and 21b. Each laminated sheet 21 includes a heat source sheet 22 formed including a heating element 31 that generates heat when electricity is applied, and a heat insulating sheet 23 disposed on the outside of the heat source sheet 22 and formed of a heat insulating material. The laminated sheets 21 are disposed to face each other, and the peripheral parts are connected to each other, and are configured not to have a gusset part. In this way, the laminated sheets 21a and 21b form a bag-shaped main body 2 having an opening 2a that can be opened and closed freely, and not to have a gusset part. The connection part 41 is electrically connected to the heating element 31 and exposed to the outside of the main body 2. The power supply part 43 is electrically connected to the connection part 41.
[0095] According to such a bag-type cooking device 1, since it has a configuration without a gusset, heat is easily transferred to the food to be cooked. Therefore, the food to be cooked can be cooked without heating the inside of the main body 2 to an unnecessarily high temperature. [Explanation of symbols]
