Description

  The present invention relates to a holding configuration of a heating coil in an induction heating cooker used in general households and the like.

  Conventionally, this type of induction heating cooker has a top plate made of crystallized glass or the like, holds the lower surface of the peripheral edge of the top plate with an under frame, and mechanically fixes the top plate and the under frame around the top plate. For example (see Patent Document 1).

  FIG. 5 shows a cross-sectional view of a main part of a conventional induction heating cooker described in Patent Document 1. As shown in FIG. As shown in FIG. 5, in the top portion, a top plate 11 composed of a ceramic plate or the like on which a pan (not shown) is placed is supported from below by a top plate support surface 13 of the under frame 12, and The top plate support surface 13 is bonded and fixed with a heat-resistant adhesive 14. Further, the side surface of the top plate 11 is covered with the top frame 15 so as to cover the entire circumference, and an adhesive 14 is filled between the top surface of the top plate 11 and the back surface of the top frame 15.

  An outer frame 16 constituting a main body (housing) is provided below the underframe 12. The underframe 12 has a main body support surface 17 formed outside the top plate support surface 13, and the main body is supported by placing the main body support surface 17 on the cabinet 18.

JP 2005-265 211 A

  In recent years, induction cooking appliances that employ a frameless design have been increasing. In this type of induction heating cooker, the top frame 15 in the conventional configuration is removed, and the top plate 11 is generally fixed to the under frame 12 only with an adhesive. On the other hand, the heating coil unit 20 is pressed against the back surface of the top plate 11 by a spring 23 in order to ensure a constant gap between the heating coil and the top plate 11 as in the configuration of the conventional example. Accordingly, since the top plate 11 and the underframe 12 are always applied with a force in the peeling direction, the adhesive force is lowered due to deterioration of the adhesive over time of the adhesive 14 that bonds the top plate 11 and the underframe 12. 12 has a problem in terms of durability that the top plate 11 is separated.

  Even if an attempt is made to secure a gap between the heating coil 20 a and the top plate 11 by fixing the heating coil unit 20 to the outer shell 16 without depending on the urging force by the spring 23, the dimensions of each component such as a warp of the outer shell 16. Depending on the accuracy, there is a limit to maintaining a certain gap. Further, if the biasing force of the spring 23 is weakened, the force in the peeling direction applied to the adhesive 14 can be reduced. However, if the biasing force is weak, the heating coil unit 20 can be moved inside the main body when dropped or vibrated during product transportation. Since the large position fluctuation occurs, the glass top plate 11 is easily broken. Therefore, pressing the heating coil unit 20 toward the top plate 11 side, that is, upward by the spring 23 with an urging force of a certain level or more ensures an appropriate gap between the heating coil 20a and the top plate 11, and robustness against dropping and vibration. This is a necessary condition for securing.

  However, in the configuration in which the top plate 11 and the underframe 12 are mechanically sandwiched using the top frame 15 as described above, the frameless structure cannot be achieved, and the degree of freedom in designing the top portion is limited. . Further, since the top plate 11 and the under frame 12 are sandwiched simultaneously by caulking the top frame 15, the structure is complicated and the time required for assembly is increased, resulting in a high cost. On the other hand, when the frameless design is adopted with the conventional configuration, there is a problem in the reliability of the top plate bonding and fixing as described above.

  The present invention solves the above-mentioned conventional problems, and has the necessary holding coil holding force 20 and sufficient drop-vibration resistance, while the top plate 11 and the underframe 12 are provided only on the top frame 15. It is an object to provide an induction heating cooker that can achieve both the design and the reliability of the adhesive fixing configuration with the top plate with a simple and inexpensive configuration without depending on ensuring the reliability of the adhesion between the plates. And

  In order to solve the conventional problem, an induction heating cooker according to the present invention includes a top plate that constitutes an upper part of a main body and on which a pan is placed, a heating coil that is provided below the top plate and heats the pan, and A heating coil unit having a coil base for supporting the heating coil, an outer shell whose upper surface is covered with the top plate and constituting the lower portion of the main body, and held by the outer shell directly or via an inclusion, the coil base A plurality of elastic bodies that are biased to the bottom plate, and an underframe that is bonded and fixed to the lower surface of the top plate and fastened to the outer shell, and that supports the top plate from below. The upward movement is restricted by the frame, and the other part is moved upward by the top plate without going through the under frame. One in which movement to have a configuration that is regulated.

  As a result, the force that the heating coil unit pushes up the upper top plate is received by the outer shell via the underframe, so the force in the peeling direction applied to the adhesive fixing part between the top plate and the underframe is reduced accordingly. can do. Therefore, while maintaining the biasing force of the elastic body that biases the heating coil unit upward to the extent that the heating coil unit can be stably supported by dropping or impacting the main body, the reliability of adhesion of the adhesive fixing portion Can be increased.

The perspective view of the induction heating cooking appliance in Embodiment 1 of this invention Front sectional view of the induction heating cooker Top view of the heating coil unit of the induction heating cooker Sectional drawing which shows the frame structural example added to the top plate of the induction heating cooking appliance Cross-sectional view of the main part of a conventional induction heating cooker The induction heating cooker of the present invention achieves both sufficient design resistance and reliability in bonding and fixing the top plate with a simple and inexpensive configuration while ensuring sufficient drop vibration resistance. It can be made to.

  1st invention comprises the top plate which comprises a main body upper part and mounts a pan, the heating coil unit which is provided under the top plate and heats the pan, and has a coil base which supports the heating coil, An outer shell whose upper surface is covered with the top plate and constituting the lower part of the main body, a plurality of elastic bodies that are held by the outer shell directly or via an inclusion and bias the coil base upward, and the top plate An underframe that is adhesively fixed to the lower surface of the plate and fastened to the outer shell and supports the top plate from below, and the coil base is restricted from moving upward by the underframe, and the other portion. Is configured such that upward movement is restricted by the top plate without using the underframe.

  With this configuration, the force that the heating coil unit pushes up the upper top plate is received by the outer frame that is fastened to the under frame, and accordingly, the adhesive fixing portion between the top plate and the under frame. The force in the peeling direction applied to can be reduced. Therefore, while maintaining the biasing force of the elastic body that biases the heating coil unit upward to the extent that the heating coil unit can be stably supported by dropping or impacting the main body, the reliability of adhesion of the adhesive fixing portion Can be increased.

  Specifically, since the heating coil unit can be firmly pressed against the underframe, a sufficient drop vibration resistance performance can be secured without significantly reducing the holding force of the heating coil unit. For example, a top frame that sandwiches the top plate is not necessary, and the degree of freedom in design at the top portion is improved. Or, the place that receives the biasing force of the elastic body, that is, the portion that regulates the vertical position of the heating coil unit is divided into the underframe and the top plate, and the biasing force of the elastic body is divided and received, so that the underframe Therefore, it is possible to make the holding structure of the top plate simple and inexpensive, and to achieve both design and reliability in bonding and fixing the top plate.

  According to the second invention, in particular, the total force of the urging forces of the plurality of elastic bodies applied to the top plate of the first invention is made smaller than the weight of the top plate, so that the top plate and the underframe are bonded and fixed. Since it is not applied to the part as a force in the peeling direction in a normal state, the reliability of adhesion in the adhesion fixing part can be further increased.

  In particular, the third invention includes a second heating coil for heating the second pan placed on the top plate adjacent to the heating coil unit of the first or second invention, and the heating coil and the second Since the other part of the coil base is positioned between the heating coils, the other part is restricted from moving upward by the top plate without going through the under frame. It is not necessary to provide it in the vicinity of a part of the outer wall, and it is only necessary to exist in the vicinity of the outer wall surface, and the underframe can be made smaller and simpler.

  According to a fourth invention, in particular, the heating coil unit according to any one of the first to third inventions is a first elastic body that is the elastic body provided at a position closer to the underframe than the center of gravity of the heating coil; A second elastic body that is the elastic body provided at a position farther from the underframe than the center of gravity; and a distance from the center of gravity to a point of application of the resultant force of the second elastic body against the coil base. By making the distance from the center of gravity to the point of action in the planar direction of the resultant force of the urging force of the first elastic body against the coil base, the action point of the resultant force of the first elastic body is The first elastic body is closer to the center of gravity than the point of action of the resultant force, and the load of the heating coil unit is applied to the first elastic body larger than that of the second elastic body. Action to separate the top plate and the under frame is reduced because the under-frame is subjected. Therefore, even if the urging force of the first elastic body is set large, the reliability of the bonded portion between the top plate and the under frame can be maintained. In addition, the resultant force of the urging force of the second elastic body that acts on the top plate without passing through the under frame is larger than the resultant force of the urging force of the first elastic body when the action of separating the top plate and the under frame is larger. Since the point of action of the resultant force of the second elastic body is farther from the center of gravity than the point of action of the resultant force of the urging force of the first elastic body, the point of action of the urging force of the first elastic body is A load of the heating coil unit smaller than the action point is applied. Therefore, even if the resultant force of the second elastic body is set to a small value, it is possible to obtain a sufficient suppression effect against the ramp of the heating coil unit at the time of dropping / vibration. It is possible to further improve the reliability with respect to dropping and vibration while securing the property.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)

It is shown.

  In FIG. 1, a top plate 32 for placing a pan (not shown) is provided on the upper surface of a main body 31 that is a casing, and a top plate 32 is provided on the upper surface for indicating a position for placing the pan. A circular cooking zone display 33 is printed. The induction heating cooker in the present embodiment is of a type having four cooking zone displays 33. The lower part of the main body 31 is made of a sheet metal, and is formed by an outer shell 34 having an opening in the upper portion and formed in a substantially box shape with a bottom. The outer shell 34 is formed in the opening of a kitchen cabinet (not shown). By dropping and placing the top of the top plate 32 and the flange 34 provided around the upper part of the outer shell 34 on the periphery of the opening of the kitchen cabinet, the top of the kitchen cabinet is positioned higher than the flange of the top plate 32 and the outer shell 34. An induction heating cooker having a pan mounting surface is installed. In the present embodiment, a frameless design in which a frame provided around the top plate 32 is not provided is employed in order to make the top plate 32 positioned on the upper surface of the kitchen cabinet clean and simple.

  In FIG. 2, a heating coil unit 37 having a heating coil 35 for induction heating of the pan and a coil base 36 on which the heating coil 35 is placed and supported from below is displayed below the top plate 32 in the cooking zone display in FIG. It is arranged at a position facing 33. The coil base 36 is made of aluminum having a high magnetic shielding effect in order to prevent the magnetic flux generated from the heating coil 35 from affecting the inverter circuit (not shown) for driving the heating coil 35 provided below the heating coil unit 37. It consists of a plate. The heating coil unit 37 is provided between a heating coil 35 and a coil base 36 and is provided with a ferrite core 38 for absorbing a magnetic flux generated from the heating coil 35 and suppressing a downward magnetic flux. An insulating mica board 39 that insulates the core 38 from the heating coil 35 and an insulating mica board 40 that is placed on the heating coil 35 and insulates radiant heat from the pan are provided.

  An underframe 41 is bonded and fixed to the lower surface of the top plate 32, and the top plate 32 and the outer shell 34 constituting the lower portion of the main body 31 are fixed by fastening the underframe 41 and the outer shell 34 with screws 42. It has been broken. The lower surface of the top plate 32 and the under frame 41 are fixed by an adhesive 43 poured into a concave bead portion 41 b provided on the upper surface portion 41 a of the under frame 41. The under frame 41 has an outer vertical wall 44a and an inner vertical wall 44b for maintaining strength, and the outer vertical wall 44a close to the side surface of the outer shell 34 is fastened to the side surface of the outer shell 34 by a screw 42.

  The outer shell 34 is formed with a step bottom surface 45 in the middle of the left and right side surfaces. One of the coil bases 36 extends from the lower side of the heating coil 35 to the vicinity of the side surface of the outer shell 34, and the lower surface is urged upward by the first elastic body 46 a provided on the step bottom surface 45. This urging force causes the upper surface 36a of the coil base 36 to abut the lower end surface of the inner vertical wall 44b of the under frame 41, and the under frame 41 is located above the coil base 36 that has received the urging force of the first elastic body 46a. The movement to is regulated. In the present embodiment, the force of the first elastic body 46a is efficiently transmitted to the underframe 41 by providing the outer vertical wall 44a on which the urging force acts and the first elastic body 46a as close as possible.

  The other side of the coil base 36 extends from below the heating coil 35 to the vicinity of the center of the outer shell 34, and the lower surface is raised by the second elastic body 46 b provided on the support base 47 formed on the bottom surface of the outer shell 34. When the end surface 48a of the vertical wall 48 provided at the end of the coil base 36 is brought into contact with the top plate 32, the top plate 32 receives the urging force of the second elastic body 46b above the coil base 36. The movement to is regulated. In the present embodiment, the force of the second elastic body 46b is efficiently transmitted to the top plate 32 by providing the vertical wall 48 on which the urging force acts and the second elastic body 46b as close as possible.

  The total urging force of the second elastic body 46b applied to the top plate 32 is the total applied to the top plate 32 of the second elastic body 46b in the heating coil unit 37 corresponding to the four cooking zone displays 33 in the present embodiment. However, the total sum may be set smaller than the weight of the top plate 32. In the present embodiment, the first elastic body 46a and the second elastic body 46b employ coil springs, but there is no problem even if a member other than the coil spring is used as long as the member has an appropriate elastic force. .

  As shown in FIG. 3, two first elastic bodies 46a provided in the vicinity of the underframe 41 (see FIG. 2) and two first elastic bodies 46a in the vicinity of the vertical wall 48 (see FIG. 2) are provided for the heating coil unit 37. One 2 elastic body 46b is provided. The resultant force of the urging force of the second elastic body 46b applied to the top plate 32 from the center of gravity C of the heating coil 35, which is a constituent member of the heating coil unit 37 (in this embodiment, since the number of the second elastic body 46b is one, 1 The distance E to the application point D of the urging force for each piece) is larger than the distance G to the application point F of the resultant force of the urging force of the first elastic body 46a.

  About the structure of the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In the present embodiment, the top plate 32 that constitutes the upper part of the main body and on which the pan is placed, the heating coil 35 that is provided below the top plate 32 and that heats the pan, and the coil base 36 that supports the heating coil 35 are provided. A unit 37, an outer shell 34 whose upper opening 34a is covered by the top plate 32 and constituting the lower portion of the main body 31, and a plurality of elastic members that are held by the outer shell 34 directly or via an inclusion and bias the coil base 36 upward. A first elastic body 46a and a second elastic body 46b which are bodies, and an underframe 41 which is bonded and fixed to the lower surface of the top plate 32 and fastened to the outer shell 34, and supports the top plate 32 from below.

  In addition, the upper end of the upper surface 36 a that is a part of the coil base 36 is restricted from moving upward by the inner vertical wall 44 b of the underframe 41, and the coil base 36 has an upper end of the vertical wall 48 that is another part of the coil base 36. However, the upward movement is restricted by the top plate 32 without using the underframe 41.

  With this configuration, the total force directly applied to the top plate 32 from the heating coil unit 37 pushed up by the elastic body 47b biased upward is directly bonded to the top frame 32 and the underframe 41 bonded by the adhesive 43. The fixing portion is not applied as a force in the peeling direction, and the total force of the heating coil unit 37 pushing up the top plate 32 is shared by the outer shell 34 to which the under frame 41 is fastened. Therefore, by reducing the force in the peeling direction applied to the adhesive fixing part between the top plate 32 and the underframe 41, the reliability of the adhesion of the adhesive fixing part can be increased.

  In addition, since the urging force of the first elastic body 46a is applied to the under frame 41, a large peeling direction force is applied to the adhesive fixing portion between the top plate 32 and the under frame 41 bonded by the adhesive 43. Without being heated, the heating coil unit 37 can be firmly pressed against the underframe 41. Accordingly, even when the product is dropped or vibrated during product transportation or the like, the heating coil unit 37 can be firmly prevented from being violated, and sufficient anti-drop vibration performance can be ensured.

  Further, since a top frame for mechanically sandwiching the top plate 32 can be eliminated in order to prevent peeling of the adhesive fixing portion, the degree of freedom in design at the top portion is improved.

  Moreover, since the place which receives the urging force of the first elastic body 46a and the second elastic body 46b is divided into the under frame 41 and the top plate 32, the urging force of all of the first elastic body 46a and the second elastic body 46b is reduced. The frame 41 need not be received, and the size of the underframe 41 can be reduced.

  As described above, since the adhesive strength required to reliably fix the top plate 32 and the under frame 41 can be reduced, the top frame in the conventional induction heating cooker shown in FIG. In addition, the dependence on the member that mechanically fixes the top plate 32 and the underframe 41 can be reduced, or such a member can be omitted. Therefore, the fixing structure of the top plate 32 and the under frame 41 is simplified, and the assembly time is also reduced. Therefore, the adhesive fixing structure of the top plate 32 is improved in design and inexpensive while maintaining reliability. Can be realized at the same time.

  Further, in the present embodiment, when the total force due to the urging force of the first elastic body 46a and the second elastic body 46b applied from the heating coil unit 37 to the top plate 32 is smaller than the weight of the top plate 32, Since the urging force is not applied as a force in the peeling direction to the adhesive fixing portion of the top plate 32 and the underframe 41 by the adhesive 43 in a normal state, the reliability of adhesion in the adhesive fixing portion can be further improved. .

  Moreover, in this Embodiment, it is adjacent to the heating coil 35, is provided with the 2nd heating coil 35a which heats another pan, and is another part of the coil base 36 between the heating coil 35 and the 2nd heating coil 35a. By adopting a configuration in which the vertical wall 48 is located, the underframe 41 can be configured to be present only in the vicinity of the outer wall surface of the outer shell 34, and the underframe 41 can be configured to be smaller and simpler. A simple and inexpensive induction heating cooker can be realized.

  In the present embodiment, the heating coil unit 37 includes a first elastic body 46 a that is an elastic body provided at a position closer to the underframe 41 than the center of gravity C of the heating coil 35, and is farther from the underframe than the center of gravity C. A second elastic body 46b, which is an elastic body provided at a position, and a distance E in the planar direction from the center of gravity C to the point of action D of the resultant force of the urging force of the second elastic body 46b, from the center of gravity C to the first elastic body. The distance G in the plane direction to the point of action F of the resultant force of the urging force 46a is made larger.

  With this configuration, the center of gravity C of the relatively heavy heating coil 35 is biased toward the underframe 41 on the coil base 36 among the components constituting the induction heating cooker. Since the under frame 41 is fixed to the outer frame 34, the outer frame 34 receives the urging force of the first elastic body 46 a applied to the under frame 41, so that the urging force is not directly applied to the top plate 32 as it is. Therefore, even if the urging force of the first elastic body 46a is set to be large, no great force in the peeling direction is applied to the adhesive fixing portion between the top plate 32 and the under frame 41 bonded by the adhesive 43. That is, the urging force of the first elastic body 46a can be increased to counter the load of the heating coil unit 37 applied to the center of gravity C.

  On the other hand, since the urging force of the second elastic body 46b applied directly to the top plate 32 is away from the center of gravity C, even if it is set to a small value, it has a sufficient suppression effect against the ramping of the heating coil unit 37 during dropping and vibration. There is an effect that can be obtained.

  In this way, the urging force of the second elastic body 46b is made smaller than the urging force of the first elastic body 46a, and the top plate 32 and the underframe 41 bonded by the adhesive 43 are excessively peeled off from each other. At the same time that the direction force is not applied, for example, the heating coil unit 37 is moved due to the drop / vibration of the main body, and the top plate 32 is broken or the internal parts are broken, resulting in lower reliability. It is something that can be avoided.

  Although the present embodiment adopts a structure that adopts a frameless design, for example, as shown in FIG. 4, a top frame 51 for design that does not have a function of holding the top plate 32 or for protecting the end of the top plate 32. May be attached to the end portion of the top plate 32 with an adhesive member 52 such as an adhesive or a double-sided tape. Thereby, it is possible to provide an induction heating cooker having a design with a frame with a simple and inexpensive configuration.

  Further, in the present embodiment, whether or not the sum of the forces due to the urging forces of the first elastic body 46a and the second elastic body 46b applying the urging force to the top plate 32 is smaller than the own weight of the top plate 32. In a state where the adhesion between the frame 41 and the top plate 32 is eliminated, it can be easily identified by visually observing whether or not the top plate 32 is lifted from the upper end surface of the outer shell 34 by the urging force of the entire second elastic body 46b. Can do.

  As described above, the induction heating cooker according to the present invention has a configuration in which the heating coil unit is biased to the top plate, ensures a certain gap between the top plate and the heating coil, and is attached to the top plate. The power can be reduced, and the present invention can be applied to the use of an induction heating cooker that adopts a similar configuration.
