Summary of the Invention

Problems to be Solved by the Invention

[0004] In some cases, it is desirable to have one of the heating sections on the top plate (for example, the first heating section) be a combustion-type heating section that uses fuel as a heat source, in order to enable frying pan tossing and tossing with high heating capacity. In this case, if a cooking container such as a pot is placed in another heating section (for example, the third heating section), it is necessary to move the frying pan back and forth to prevent it from colliding with the cooking container. In a layout of the first heating section, second heating section, third heating section and heating chamber, such as the heating cooker in Patent Document 1, when the frying pan is moved back and forth in this way, the user's hand, which is holding the handle of the frying pan, passes above the opening of the heating chamber. Hot air may leak from the heating chamber through the opening of the heating chamber, for example, if the door member is open after heating by the heating chamber. Therefore, if the user's hand, which is holding the handle of the frying pan, passes above the opening of the heating chamber, the hot air from the heating chamber may hit the user's hand and cause discomfort to the user.

[0005] This specification provides a technology that can improve user comfort when performing stir-frying using the combustion-type heating element in a cooking appliance equipped with one combustion-type heating element and two non-combustion-type heating elements on the top plate, and a heating chamber inside the main body. [Means for solving the problem]

[0006] In the first embodiment, the cooking appliance may comprise a main body having a front surface facing the user, a top plate positioned on the upper part of the main body, a first heating section, a second heating section, and a third heating section provided on the top plate, and a heating chamber provided inside the main body. The first heating section may be a combustion-type heating section that uses fuel as a heat source. The second heating section and the third heating section may be non-combustion-type heating sections that use electricity as a heat source. An opening communicating with the heating chamber may be formed on the front surface. The main body may be provided with a door member that opens and closes the opening. When the cooking appliance is viewed from above in a plan view, the center position of the third heating section may be positioned further back than the center position of the second heating section in the front-rear direction. When the cooking appliance is viewed from above in a plan view, the center position of the first heating section may be positioned to one side of the left-right center line of the door member, and the center positions of the second heating section and the third heating section may be positioned to the other side of the left-right center line of the door member.

[0007] With the above configuration, when cooking with a frying pan in the first heating section while a cooking container such as a pot is placed in the third heating section, it is possible to prevent the user's hand, which is holding the handle of the frying pan, from passing over the opening of the heating chamber when moving the frying pan back and forth to prevent it from colliding with the cooking container. Therefore, it is possible to prevent the hot air from the heating chamber from hitting the user's hand and causing discomfort to the user. With the above heating appliance, it is possible to improve the user's comfort when cooking with a frying pan using the first heating section, which is a combustion-type heating section.

[0008] In the second embodiment, in the heating appliance of the first embodiment, when the heating appliance is viewed from above in a plan view, the center position of the first heating section may be positioned further rearward than the center position of the second heating section in the front-to-back direction.

[0009] With the above configuration, even when a cooking container with a long handle, such as a frying pan, is placed on the first heating section, it is possible to prevent the handle from protruding significantly forward from the cooking appliance. This prevents it from interfering with the user's cooking work.

[0010] In a third embodiment, in the cooking appliance of the first or second embodiment, the second heating unit and the third heating unit may be electromagnetic induction type heating units.

[0011] In addition to electromagnetic induction heating units, non-combustion heating units that use electricity as a heat source also include halogen heaters and heating wires. Of these, electromagnetic induction heating units have the advantage of having a larger heating capacity compared to other non-combustion heating units, and although the cooking container becomes hot, the heating unit itself does not become hot. With the above configuration, the heating capacity of the second and third heating units can be increased, and the heating unit itself can be prevented from becoming hot.

[0012] In the fourth embodiment, in the cooking appliance of any one of the first to third embodiments, the heating capacity of the third heating section may be less than the heating capacity of the second heating section.

[0013] If the heating capacity of the third heating section is less than that of the second heating section, it is assumed that the second heating section will be used daily and the third heating section will be used as a backup. With the above configuration, the second heating section, which is used daily, is located on the front side from the user's perspective, and the third heating section, which is used as a backup, is located on the back side from the user's perspective, thus improving user convenience.

[0014] In the fifth embodiment, in a cooking appliance of any one of the first to fourth embodiments, when the cooking appliance is viewed from above in a plan view, the left-right center line of the door member may be offset to the other side with respect to the left-right center line of the top plate.

[0015] According to the above configuration, a wider space can be secured around the first heating element on the top plate, improving user convenience when performing stir-frying using the first heating element.

[0016] In the sixth embodiment, in a cooking appliance of any one of the first to fifth embodiments, when the cooking appliance is viewed from above in a plan view, the center position of the first heating section may be located on one side of the left-right center line of the top plate, and the center positions of the second heating section and the third heating section may be located on the other side of the left-right center line of the top plate.

[0017] According to the above configuration, a wider space can be secured around the first heating element on the top plate, improving user convenience when performing stir-frying using the first heating element. [Brief explanation of the drawing]

[0018] [Figure 1] This is a perspective view of the heating appliance 2 of the embodiment. [Figure 2] This is a top view of the heating appliance 2 of the embodiment. [Figure 3] This is a top view of the comparative example heating appliance 32. [Figure 4] This is a top view of a heating appliance 42 of another embodiment. [Figure 5] This is a top view of a heating appliance 52 of yet another embodiment. [Modes for carrying out the invention]

[0019] (Examples) The cooking heater 2 of this embodiment shown in Fig. 1 is an built-in stove that is used by being incorporated into a system kitchen. The cooking heater 2 includes a main body 4 whose front surface 4a is exposed on the front side of the system kitchen, and a top plate 6 that is disposed on the upper part of the main body 4 and is exposed on the countertop of the system kitchen. In the following description, the front-back direction and left-right direction of the cooking heater 2 mean the front-back direction and left-right direction when the front side of the system kitchen is defined as the front and the back side of the system kitchen is defined as the back. For this reason, it should be noted that the front-back direction and left-right direction of the cooking heater 2 are different from the front-back direction and left-right direction as seen by a user who uses the cooking heater 2.

[0020] The top plate 6 is provided with a first heating unit 8, a second heating unit 10, and a third heating unit 12. The first heating unit 8 is a combustion-type heating unit that heats a cooking target using a fuel such as city gas as a heat source. The first heating unit 8 includes a cooking grate 8a on which a cooking container (for example, a pot) can be placed, and a burner 8b that heats the cooking container placed on the cooking grate 8a. The second heating unit 10 and the third heating unit 12 are non-combustion-type heating units that heat a cooking target using electricity as a heat source. The second heating unit 10 and the third heating unit 12 include placement marks 10a, 12a indicating a range where a cooking container (for example, a pot) can be placed, and induction heating (IH) coils (not shown) that are housed in the main body 4 and heat the cooking container placed on the placement marks 10a, 12a. Alternatively, the second heating unit 10 and / or the third heating unit 12 may include a halogen heater or a heating wire (not shown) that heats the cooking container placed on the placement marks​​​Inside the main body 4, a heating chamber 14 is provided. The heating chamber 14 may be a combustion-type heating chamber (for example, a heating chamber equipped with a burner) that heats the cooking target using a fuel such as city gas as a heat source, or a non-combustion-type heating chamber (for example, a heating chamber equipped with a halogen heater or a heating wire) that heats the cooking target using electricity as a heat source. Further, the heating chamber 14 may be a grill-type heating chamber or an oven-type heating chamber. In the heating chamber 14, food ingredients and cooking containers can be taken in and out through an opening 14a formed in the front surface 4a. The opening 14a is opened and closed by a door member 14b. The heating chamber 14 communicates with an exhaust port 14c provided at the rear of the top plate 6. The exhaust generated by cooking in the heating chamber 14 is discharged to the outside through the exhaust port 14c.

[0022] On the left side of the door member 14b on the front surface 4a of the main body 4, a first stove operation knob 16, a second stove operation knob 18, a third stove operation knob 20, and a stove operation panel 22 are provided. The first stove operation knob 16 accepts the start operation and end operation of heating by the first heating unit 8, and the adjustment operation of the heating amount of the first heating unit 8. The second stove operation knob 18 accepts the start operation and end operation of heating by the second heating unit 10, and the adjustment operation of the heating amount of the second heating unit 10. The third stove operation knob 20 accepts the start operation and end operation of heating by the third heating unit 12, and the adjustment operation of the heating amount of the third heating unit 12. The stove operation panel 22 includes a display unit 22a and an operation unit 22b. The display unit 22a displays the operating states of the first heating unit 8, the second heating unit 10, and the third heating unit 12. The operation unit 22b accepts the start operation and end operation of automatic cooking using the first heating unit 8, the second heating unit 10, and / or the third heating unit 12, and the setting operation for automatic cooking.

[0023] On the front surface 4a of the main unit 4, to the right of the door member 14b, there is a heating chamber operation knob 24 and a heating chamber operation panel 26. The heating chamber operation knob 24 accepts the start and end operations of heating by the heating chamber 14, and the adjustment of the heating amount of the heating chamber 14. The heating chamber operation panel 26 comprises a display unit 26a and an operation unit 26b. The display unit 26a displays the operating status of the heating chamber 14, etc. The operation unit 26b accepts the start and end operations of automatic cooking using the heating chamber 14, and setting operations for automatic cooking, etc.

[0024] As shown in Figure 2, when the top plate 6 is viewed from above in a plan view, the left-right centerline CL1 of the door member 14b is offset to the right of the left-right centerline CL2 of the top plate 6. The center position CP1 of the first heating section 8 is located to the left of the left-right centerline CL1 of the door member 14b and the left-right centerline CL2 of the top plate 6. The center positions CP2 of the second heating section 10 and CP3 of the third heating section 12 are located to the right of the left-right centerline CL1 of the door member 14b and the left-right centerline CL2 of the top plate 6. The center positions CP2 of the second heating section 10 and CP3 of the third heating section 12 are located side by side, front to back. The center position CP2 of the second heating section 10 is located in front of the center position CP3 of the third heating section 12 and the center position CP1 of the first heating section 8. The center position CP3 of the third heating section 12 is located behind the center position CP2 of the second heating section 10 and the center position CP1 of the first heating section 8.

[0025] Figure 3 shows the arrangement of the first heating section 8, the second heating section 10, and the third heating section 12 in another cooking appliance 32 as a comparative example. Cooking appliance 32 has the same configuration as cooking appliance 2, with only the arrangement of the first heating section 8, the second heating section 10, and the third heating section 12 differing from cooking appliance 2. In cooking appliance 32, the center position CP1 of the first heating section 8 is located to the left of the left-right center line CL1 of the door member 14b and the left-right center line CL2 of the top plate 6. The center position CP2 of the second heating section 10 is located to the right of the left-right center line CL1 of the door member 14b and the left-right center line CL2 of the top plate 6. The center position CP3 of the third heating section 12 is located to the left of the left-right center line CL1 of the door member 14b and is located on the left-right center line CL2 of the top plate 6. The center positions CP1 of the first heating section 8 and CP2 of the second heating section 10 are arranged side by side. The central position CP3 of the third heating section 12 is located further back than the central position CP2 of the second heating section 10 and the central position CP1 of the first heating section 8.

[0026] Consider the case where a double-handled pot TP is placed on the third heating section 12 of the cooking appliance 32, and a frying pan FP is being tossed in the first heating section 8. In the cooking appliance 32, the first heating section 8 is positioned close to the third heating section 12, so if the frying pan FP is moved back and forth, it will collide with the double-handled pot TP placed on the third heating section 12. For this reason, when tossing the frying pan FP in the first heating section 8, the frying pan FP must be moved back and forth between the front right and the rear left. When moving the frying pan FP back and forth between the front right and the rear left, the user's hand, which is gripping the handle FH of the frying pan FP, will pass over the opening 14a of the heating chamber 14. Hot air from the heating chamber 14 may leak out through the opening 14a of the heating chamber 14, for example, if the door member 14b is open after heating by the heating chamber 14. Therefore, if the user's hand, which is gripping the handle FH of the frying pan FP, passes above the opening 14a of the heating chamber 14, the hot air from the heating chamber 14 may hit the user's hand, potentially causing discomfort to the user.

[0027] Similarly, consider the case of the cooking appliance 2 shown in Figure 2, where a double-handled pot TP is placed on the third heating section 12, and a frying pan FP is being tossed in the first heating section 8. Unlike the cooking appliance 32 shown in Figure 3, in the cooking appliance 2 shown in Figure 2, the first heating section 8 is positioned away from the second heating section 10 and the third heating section 12. Therefore, even when the frying pan FP is moved back and forth, there is no risk of the double-handled pot TP on the third heating section 12 colliding with the frying pan FP. As a result, when tossing the frying pan FP in the first heating section 8, the frying pan FP can be moved back and forth, and the user's hand, which is gripping the handle FH of the frying pan FP, can be prevented from passing over the opening 14a of the heating chamber 14. This prevents the hot air from the heating chamber 14 from hitting the user's hand and causing discomfort to the user.

[0028] Furthermore, as shown in Figure 4 for the heating appliance 42, the center position CP1 of the first heating section 8 may be positioned to the right of the left-right center line CL1 of the door member 14b and the left-right center line CL2 of the top plate 6, and the center position CP2 of the second heating section 10 and the center position CP3 of the third heating section 12 may be positioned to the left of the left-right center line CL1 of the door member 14b and the left-right center line CL2 of the top plate 6. The heating appliance 42 has the same configuration as the heating appliance 2, with the only difference being the arrangement of the first heating section 8, the second heating section 10 and the third heating section 12. In the heating appliance 42 as well, when a double-handled pot TP is placed on the third heating section 12 and cooking with a frying pan FP is performed in the first heating section 8, it is possible to prevent the user's hand, which is gripping the handle FH of the frying pan FP, from passing over the opening 14a of the heating chamber 14, thereby preventing the hot air from the heating chamber 14 from hitting the user's hand and causing discomfort to the user.

[0029] Alternatively, as shown in Figure 5 for the heating appliance 52, the heating chamber 14, opening 14a, and door member 14b may be arranged such that the left-right center line CL1 of the door member 14b coincides with the left-right center line CL2 of the top plate 6. The heating appliance 52 has the same configuration as the heating appliance 2, differing only in the arrangement of the heating chamber 14, opening 14a, and door member 14b. In the heating appliance 52 as well, when a double-handled pot TP is placed on the third heating section 12 and cooking is performed by tossing a frying pan FP in the first heating section 8, it is possible to prevent the user's hand, which is gripping the handle FH of the frying pan FP, from passing over the opening 14a of the heating chamber 14, thereby preventing the hot air from the heating chamber 14 from hitting the user's hand and causing discomfort to the user.

[0030] In addition, in the heating appliance 2 in Figure 2, the heating appliance 42 in Figure 4, and the heating appliance 52 in Figure 5, the center position CP1 of the first heating section 8 may be approximately aligned with the center position CP2 of the second heating section 10, or approximately aligned with the center position CP3 of the third heating section 12, in the front-to-back direction. Furthermore, in the left-to-right direction, the center position CP2 of the second heating section 10 may be offset to the right or left of the center position CP3 of the third heating section 12.

[0031] As described above, in one or more embodiments, the cooking appliance 2,42,52 comprises a main body 4 having a front surface 4a facing the user, a top plate 6 positioned on the upper part of the main body 4, a first heating section 8, a second heating section 10, and a third heating section 12 provided on the top plate 6, and a heating chamber 14 provided inside the main body 4. The first heating section 8 is a combustion-type heating section that uses fuel as a heat source. The second heating section 10 and the third heating section 12 are non-combustion-type heating sections that use electricity as a heat source. An opening 14a communicating with the heating chamber 14 is formed in the front surface 4a. The main body 4 is provided with a door member 14b that opens and closes the opening 14a. When the cooking appliance 2,42,52 is viewed from above in a plan view, the center position CP3 of the third heating section 12 is positioned further rearward than the center position CP2 of the second heating section 10 in the front-to-back direction. When the heating appliances 2, 42, and 52 are viewed from above in a plan view, the center position CP1 of the first heating section 8 is located to one side of the left-right center line CL1 of the door member 14b. The center position CP2 of the second heating section 10 and the center position CP3 of the third heating section 12 are located to the other side of the left-right center line CL1 of the door member 14b.

[0032] According to the above configuration, when a cooking container TP such as a pot is placed in the third heating section 12 and tossing cooking is performed with a frying pan FP in the first heating section 8, the user's hand, which is holding the handle FH of the frying pan FP, does not pass over the opening 14a of the heating chamber 14 when moving the frying pan FP back and forth to prevent collision between the cooking container TP and the frying pan FP. Therefore, it is possible to suppress the hot air from the heating chamber 14 from hitting the user's hand and causing discomfort to the user. According to the above heating cookers 2,42, 52, it is possible to improve user comfort when tossing cooking using the first heating section 8, which is a combustion-type heating section.

[0033] In one or more embodiments of the heating appliances 2, 42, 52, when the heating appliances 2, 42, 52 are viewed from above in a plan view, the central position CP1 of the first heating section 8 is located further rearward than the central position CP2 of the second heating section 10 in the front-to-back direction.

[0034] With the above configuration, even when a cooking container FP with a long handle FH, such as a frying pan, is placed on the first heating unit 8, it is possible to suppress the handle FH from protruding significantly forward from the heating appliances 2, 42, and 52. This prevents the heating appliances 2, 42, and 52 from interfering with the user's cooking work.

[0035] In one or more embodiments of the heating cooker 2,42,52, the second heating unit 10 and the third heating unit 12 are electromagnetic induction heating units.

[0036] In addition to electromagnetic induction heating units, non-combustion heating units that use electricity as a heat source also include halogen heaters and heating wires. Of these, electromagnetic induction heating units have the advantage of having a larger heating capacity compared to other non-combustion heating units, and although the cooking container becomes hot, the heating unit itself does not become hot easily. With the above configuration, the heating capacity of the second heating unit 10 and the third heating unit 12 can be increased, and the heating unit itself can be prevented from becoming hot.

[0037] In one or more embodiments of the cooking appliance 2,42,52, the heating capacity of the third heating section 12 is smaller than the heating capacity of the second heating section 10.

[0038] If the heating capacity of the third heating unit 12 is less than that of the second heating unit 10, it is assumed that the second heating unit 10 will be used on a daily basis and the third heating unit 12 will be used as a backup. With the above configuration, the second heating unit 10, which is used on a daily basis, is located on the side closer to the user, and the third heating unit 12, which is used as a backup, is located on the side further away from the user, thus improving user convenience.

[0039] In one or more embodiments of the heating appliance 2, when the heating appliance 2 is viewed from above in a plan view, the left-right center line CL1 of the door member 14b is offset to the other side with respect to the left-right center line CL2 of the top plate 6.

[0040] With the above configuration, a wider space can be secured around the first heating element 8 on the top plate 6, improving user convenience when performing stir-frying using the first heating element 8.

[0041] In one or more embodiments of the heating appliance 2,42,52, when the heating appliance 2,42,52 is viewed from above in a plan view, the center position CP1 of the first heating section 8 is located to one side of the left-right center line CL2 of the top plate 6, and the center position CP2 of the second heating section 10 and the center position CP3 of the third heating section 12 are located to the other side of the left-right center line CL2 of the top plate 6.

[0042] With the above configuration, a wider space can be secured around the first heating element 8 on the top plate 6, improving user convenience when performing stir-frying using the first heating element 8.

[0043] Although each embodiment has been described in detail above, these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes to the specific examples illustrated above. The technical elements described in this specification or drawings exhibit technical usefulness individually or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technology illustrated in this specification or drawings can achieve multiple objectives simultaneously, and achieving even one of these objectives itself constitutes technical usefulness.
