Description

  The present invention relates to a heating cooker that heats and cooks an object to be heated via a cooking container placed on a top plate.

  Conventionally, a multi-mouth (three-mouth type here) heating cooker as shown in FIGS. 4 and 5 is roughly described in terms of its configuration. The case main body 1 requires a driving mechanism such as a heating means and a cooling fan, The top plate 2 is mainly composed of a top plate 2a provided so as to cover the top. And as said heating means, the 1st, 2nd heating means 3 and 4 which consist of induction heating coils, for example are arranged in parallel in the right and left, and the radial heater which consists of a nichrome wire as the 3rd heating means 5 in the center back is carried out. All of them are formed in a substantially circular shape.

  On the top plate 2a positioned close to and above the heating means 3, 4 and 5, a ring frame slightly larger than the circular outer shell line of each heating means 3, 4 and 5 is displayed. The 1st, 2nd, 3rd heating part 6,7,8 is formed by printing display, and it is showing to a user as an area | region which can heat cooking containers, such as a pot which is not shown in figure, for convenience. The coil diameter L of the first and second heating means 3 and 4 is usually 180 mm, and therefore the first and second heating parts 6 and 7 as the ring frame are larger in diameter. (Details will be described later).

  However, this kind of cooking device is widely used as a drop-in type incorporated in a system kitchen or the like. Generally, as shown in the schematic configuration of FIG. The width Y of the case body 1 that is standardized and thus dropped into the case is designed to be 543 mm or less, for example, less than the dimension Z. On the other hand, the top plate 2 has a lateral width dimension X (for example, 600 mm) that is slightly larger than the lateral width dimensions Z and Y so that the drop hole 10 is concealed and held at the periphery thereof. In this case, the top plate 2 is composed of a top plate 2a and a frame 2b attached to the peripheral edge thereof.

  And as a cooking container which can be applied to the 1st, 2nd heating parts 6 and 7 arranged side by side among the heating parts of top plate 2a, for example, the size of a circular pan (not shown) is, When placed on these heating units 6 and 7, the diameter of the pan is determined to be a range that does not come into contact with each other and does not protrude from the frame 2 b of the top plate 2. The maximum diameter.

  Incidentally, a practical example will be described with reference to FIG. 4. Basically, the pan has a design specification in which the pans are arranged substantially evenly in the left-right direction. In particular, the space dimension W between the left and right pans is usually secured to 30 mm so that the pans do not contact each other. At the same time, the pitch dimension V of the heating means 6 and 7 is set to 285 mm, and the allowable maximum pan diameter S is set to 255 mm (S = V−W). In addition, the space | interval dimension W of the said pan is set also considering that the handle of one pan does not contact the side surface of the other pan as much as possible, and also considering the handleability so that it can be easily grasped.

  However, in this example, the ring frames of the first and second heating units 6 and 7 are displayed in accordance with the pan diameter S, and the interval distance W between the pans is shown even if no pan is placed. It can be set and known as shown in FIG. Therefore, the ring frames of the first and second heating units 6 and 7 are equal to the maximum pan diameter S, and are larger than the coil diameter L (180 mm) of the first and second heating means 6 and 7 as described above. It turns out that there is a big relationship.

  Thus, when two pans having a maximum pan diameter S of 255 mm are placed with a space dimension W of 30 mm secured, the horizontal width X of the top plate 2 is 600 mm. The shortest distance U from the left end to the right end of the top plate 2 is only 30 mm, and as the diameter of the pan increases, a design approaching to the left and right including the heating units 6 and 7 is required. For this reason, when it is placed so that the left and right pans do not come into contact with each other in actual use, if the shortest distance U dimension to the left and right ends of the top plate 2 does not have a sufficient margin, the pan is placed sideways on the top plate 2a. There is a risk of protruding. However, the shortest distance T to the front end of the pan is set to 50 mm, which is larger than the shortest distance U to the left and right ends (T> U). It doesn't lead to overhang.

  In addition, in the drop-in type, the upper surface of the counter top 9 of the kitchen and the mounting surface of the top plate 2a are flat with the same surface from the viewpoint of usability and design. For this reason, even if the pan protrudes to the left and right, there is a risk that it will be overlooked without any significant change in the mounting state.In this case, the proper pot size and position cannot be confirmed, and the heating efficiency is reduced. There is also concern about the problem of heating by heat conduction in contact with other things. On the other hand, various cooking utensils on the counter top 9 are easy to move to the top plate 2a side. In this case, the heating units 6 and 7 and the left and right ends of the top plate 2 are close to each other as described above. There is also a possibility of heating.

In addition, in this type of multi-neck drop-in type cooking device, the improvement in usability is achieved by improving the operability of the dial or kangaroo operation unit provided on the case body (for example, Patent Document 1), or an operation unit arranged on the same upper surface as the top plate (see, for example, Patent Document 2), there are some that improve the usability of the operation unit.

  The problem we are trying to solve is that it is easy to overlook even if the cooking container such as a pan protrudes outward from the top plate, and there is a risk of causing a defective heating form. Convenience is not good.

  In order to solve the above problems, a heating cooker according to the present invention is provided in a case body so as to cover a heating means for heating an object to be heated via a cooking container and to cover the heating means. What comprises the top plate which sets up the heating part which places a cooking container, The distance of the peripheral end of the heating part on the top plate and the top plate side end is the top end of the top plate It is characterized by having an arrangement configuration that is longer than the distance between the two (invention of claim 1).

  In order to solve the above problems, the heating cooker according to the present invention is provided in the case main body so as to cover the upper part of the heating means for heating the object to be heated through the cooking container. A heating plate on which the cooking vessel is placed is set, and the heating unit is set in a circular region, and the center of the heating unit and the side end of the heating plate Is arranged longer than the distance to the front end of the top plate (invention of claim 2).

  According to the cooking device of the present invention, since the distance between the heating unit and the side end of the top plate is set to be longer than the distance at the front end, when a cooking container such as a large pot is used. However, it can prevent this from protruding to the side of the top plate, and can solve problems such as contact with other objects and incorrect heating, and if a pan that is larger than allowed is used, It is possible to provide a heating cooker that is safe and easy to use, such as being easily perceived by the user by protruding and thus avoiding erroneous use.

1 to 3 showing an embodiment in which the present invention is applied to a drop-in type cooking device.
FIG. 1 is a plan view of a cooking device alone, FIG. 2 is an external perspective view incorporated in the kitchen, and FIG. 3 is a front view showing a cutaway main portion. Among them, a schematic configuration will be described based on FIGS. 2 and 3 in particular. 1 will be described in particular with respect to the arrangement of the main parts. This heating cooker is of a so-called three-mouth type, and has a case body 21 having a rectangular box shape as in the prior art and a heat-resistant glass top plate 22a provided so as to cover the upper part of the case main body 21. It is comprised from the top plate 22 which mounts | wears with the flame | frame 22b.

  Among them, the case body 21 includes a heating unit and an operation unit 23 described later, a cooling fan (not shown), and a thermal power control of the heating unit based on a control program stored in advance by receiving input signals such as various detection signals. And a drive mechanism section such as a control circuit for driving and controlling an inverter circuit (not shown). Further, a roaster 24 provided with heating means using a sheathed heater (not shown) is formed on the left side of the operation unit 23.

  On the other hand, the top plate 22 includes a frame 22b attached to the periphery of the top plate 22a, and an intake / exhaust means to which a cover member 25 is attached is provided at the back. On the top surface of the top plate 22a, ring frames are displayed, for example, by printing the first to third heating units 26 to 28 as heating units at three locations corresponding to the heating means described later. It shows that it is a mounting area for effectively heating the cooking container that does not.

  Among them, at least the diameter dimension of the ring frame as the heating parts 26 and 27 in this embodiment is set to 300 mm, which is the same as the maximum allowable pot diameter M which will be described in detail later. Moreover, the front side top plate 22a corresponding to these heating units 26 to 28 is provided with heating power display units 29 to 31 of heating means to be described later, which are composed of a plurality of LED light emitting elements, and the operation unit The heating power is adjusted based on the setting operation by 23, and the strength level can be easily determined from the position of the lighting display.

  Thus, the heating means in the present embodiment will be described. First and second heating means 32, 33 comprising induction heating coils with different outputs at lower positions corresponding to the first and second heating units 26, 27. Are arranged side by side in the left-right direction in the figure, and corresponding to the third heating unit 28 located in the back of the center, a third heating means 34 composed of a radial heater made of nichrome wire is disposed. It is formed in a substantially circular shape, and is fixed to the upper part in the case main body 21 via an appropriate attachment member.

  Incidentally, the output of each heating means is, for example, the maximum output of 3 kilowatts (KW) in the left first heating means 32 (corresponding to the first heating unit 26), and the right second heating means 33 (second heating). The maximum output is set to 2.0 kilowatts (KW) in the unit 27), and the maximum output is set to 1.2 kilowatts (KW) in the third heating means 34 (corresponding to the third heating unit 28) of the radiant heater. Therefore, it can be used properly according to the cooking conditions.

  In addition, the coil diameter L which is a diameter dimension of the 1st, 2nd heating means 32 and 33 in a present Example is 180 mm similarly to the past. Further, magnetic shielding plates 35 and 36 made of aluminum and made of a ring-shaped horizontal plate are provided in the vicinity of the outer periphery of the first and second heating means 32 and 33 (see FIG. 3). Is preventing. However, the left end portion of the left magnetic shield plate 35 and the right end portion of the right magnetic shield plate 36 are formed with bent portions 35a and 36a bent vertically downward, for example, and so-called left and right end portions have a small horizontal portion. However, the surface area is secured by the rising portion to enable the magnetic shielding function, and the case body 21 is compactly disposed in a limited space space in the left-right direction.

  Further, here, the operation unit 23 will be described. The operation unit 23 includes various switches and operation dials corresponding to the heating means. For example, a power switch 37 and dials 38a to 38d are provided from the left in the drawing. The dial 38a has a first heating means 32 on the left side and the dial 38b has a roaster 24 (seeds). The heater 38) and the dial 38c are capable of controlling the third heating means 34 in the center, and the dial 38d is capable of controlling the second heating means 33 on the right side.

  And the heating cooker of the said structure inserts the case main body 21 so that it may drop from the drop hole 41 of the countertop 40 of the kitchen 39, as shown in FIG. Incorporated. In this case, the shape (size) of the drop hole 40 is 560 mm as the standard width dimension Z as described above, so the width dimension Y of the main body case 21 is 543 mm as in the conventional case. The width dimension A is set to 750 mm, which is 25% higher than the conventional size. Although details of the reason will be described later, this is to make it possible to place a larger-diameter pan (cooking vessel) on the left and right sides, and also the first and second heating means 32, 33 or the first and first. This is because the distance from the two heating units 26 and 27 to the left and right side ends of the top plate 22 is increased.

  Thus, enlarging the top plate 22 is to substantially enlarge the top plate 22a, and accordingly, on the first and second heating portions 26, 27 of the top plate 22a, Large-diameter pans can be juxtaposed with a predetermined interval dimension W (30 mm). Incidentally, in this embodiment, as shown in FIG. 1, the maximum pan diameter M is set to 300 mm, which is about 20% higher than the conventional one, while securing 30 mm as the interval dimension W between the pans. Therefore, the 1st, 2nd heating parts 26 and 27 which are the ring frames made into the same diameter as this pan diameter M are formed in the position distributed substantially equally right and left via 30 mm of the space | interval dimension W of a pan. Yes.

  Thus, since the pan diameter M is 300 mm, the pitch dimension E of the first and second heating means 32 and 33 which are concentric is 330 mm. Therefore, each of the first and second heating units 26 and 27 which are also concentric is used. The distance N from the center to the left and right ends of the top plate 22 is 210 mm, whereas the distance K to the front end is 200 mm, which is shorter than the distance N (K <N). In addition, the shortest distance I between the peripheral end portions and the left and right end portions of the heating units 26 and 27 is 60 mm, whereas the shortest distance H to the front end portion is set as short as 50 mm (H <I ). The center position of the distance K (200 mm) obtained from the centers of the first and second heating units 26 and 27 is slightly forward from the center position of the vertical dimension Q (406.5 mm) of the top plate 22a itself. Positioned and enabled to place the third heating section 28 in the center back.

Next, the operation of the cooking device having the above configuration will be described.
First, in order to incorporate it into the kitchen 39, the width dimension Y of the case body 21 with respect to the drop hole 41 (width dimension Z) of the countertop 40 is in the same numerical relationship (Y <Z) as in the prior art. Can be installed by drop-in.
On the other hand, when the pan is placed on the top plate 22a to be cooked, the width A of the entire top plate 22 mainly composed of the top plate 22a is increased to 750 mm, and the first and second In consideration of the case where the pans are juxtaposed to the heating parts 26 and 27, and after securing the interval dimension W (30 mm) where the pan does not contact, the maximum allowable pan diameter M (300 mm) is obtained and adjusted accordingly. The ring frames of the first and second heating portions 26 and 27 are displayed with the same diameter, and the shortest distance I from the peripheral end portion to the left and right side end portions is made larger than the shortest distance H to the front end portion (I > H).

  As a result, when a pan having a maximum pan diameter M of 300 mm is placed, the distance I to the side end described above is 60 mm, and the distance H to the front end is 50 mm. A large-sized pan can be used without protruding from the top plate 22, and when a large-sized pan exceeding the allowable dimensions is used, it is possible to suppress the protruding to the countertop 40 side which is the left and right direction as much as possible, and further the diameter In a large case, even if it protrudes, it will protrude from the front end portion where the distance is short first. This avoids the problem that the contact with the article on the countertop 40 that is almost in the same plane is always a concern, but unlike the left and right side ends, it may protrude into the front space and fall. The form of the pan can be easily recognized with a sense of crisis, and the user can easily notice the protrusion of the pan forward.

  In addition, since the shortest left and right distance I can be increased, the possibility of touching other cooking containers placed on the countertop 40 is reduced, and the first and second heating units 26 and 27 are also reduced. Can secure a sufficient distance from the side edge of the top plate 22, so that it is possible to avoid the possibility of directly heating a cooking utensil or the like that has been accidentally moved from the counter top 40 to the top plate 22.

  Moreover, the effective arrangement function of such a large-sized pan is based on the distance N (for example, 210 mm) from the center of each heating unit 26, 27 to the left and right side ends, and the distance K (for example, the front end). , 200 mm) (N> K) can be achieved in the same manner as described above. For example, when a plate having a pan diameter of 400 mm exceeding the allowable dimension is placed, there is still a margin on the side of the top plate 22. Although it does not stick out, it is almost equal to the distance K (200 mm) in the front, and there is a risk of sticking out, and the user can easily correct the notice pan to the proper usage form.

As described above, the present embodiment has the following effects.
In the above-described drop-in type heating cooker, the assembly work by dropping the case main body 21 with respect to the counter top 40 can be easily performed under the same condition setting as before, and the pan that can be placed on the top plate 22a. In other words, the diameter of the pan that can be used for so-called heating cooking can be increased, and as many pans can be used for cooking, the usability is improved.

  Moreover, the distance (I and N) on the side end side of the top plate 22 is set to the front end side with respect to the first and second heating units 26 and 27 corresponding to the first and second heating means 32 and 33. Due to the arrangement configuration set longer than the distances (H and K), the pans protrude from the side, and contact with other articles, cooking utensils moved from the counter top 40 to the top plate 22, etc. are heated by mistake. If you use a pan that is larger than the tolerance, the user can easily detect that it protrudes forward, thus avoiding misuse and making it safer and easier to use. An improved cooking device can be provided.

  The present invention is not limited to the embodiment described above and shown in the drawings. For example, in the above embodiment, the distance between the side edge and the front edge of the top plate is set based on the heating part formed on the top plate. Instead of this, it is substantially the same as the setting based on the corresponding heating means, and these heating units and heating means are preferably circular from the shape of a pan or the like, but not limited to this, may be polygonal, In addition, it is not limited to the three-port type, and other heating means such as a halogen lamp or a sheathed heater may be used. Further, in the above embodiment, the thermal power display unit is provided on the top plate and the operation unit is provided on the front surface of the case body. However, the thermal power display unit and the operation unit may be provided on the frame portion of the top plate. Various modifications can be made without departing from the scope of the present invention.
