Description

[Technical Field]

[0001] The present invention relates to a cooking device. [Background technology]

[0002] Patent Document 1 discloses a rice cooker (heating cooker) that uses a coil to induction heat a pot housed in a casing. The cooking cooker in Patent Document 1 is equipped with a heating control board (electronic board), and a radiator is attached to the heating control board. The casing is provided with a radiator support that supports the radiator from below. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-216009 Summary of the Invention [Problem to be solved by the invention]

[0004] If an impact load is applied to the cooking appliance during transportation, the impact load may be transmitted to the electronic board via the casing. Generally, it is undesirable for vibrations and impact loads to be applied to electronic boards on which semiconductors and the like are mounted. Patent Document 1 does not disclose how to suppress the vibrations and impact loads transmitted to the electronic boards.

[0005] An object of the present invention is to suppress vibrations and impact loads transmitted to an electronic board when an impact load is input to a cooking appliance. [Means for solving the problem]

[0006] One aspect of the present invention provides a cooking device comprising a casing, a support structure provided at the bottom of the casing, and an electronic board housed in a board holder fixed within the casing at a distance from the bottom, wherein the support structure has a first support portion made of a rigid body and a second support portion at least a portion of which is made of an elastic body, and the portion of the second support portion made of an elastic body penetrates the inside and outside of the casing and is positioned close to the board holder.

[0007] According to the present invention, an impact load input to a cooking appliance is transmitted to the substrate holder via the first support part made of a rigid body and the casing. When the impact load is transmitted to the substrate holder, the substrate holder abuts against the elastic part of the second support part, thereby attenuating the impact load input to the substrate holder. For example, if a member made of a rigid body or the like is placed close to the substrate holder, the impact load may be input to the substrate holder due to the substrate holder's contact with the member, but the abutment of the substrate holder with the elastic part of the second support part can suppress the input load from the other member.

[0008] The substrate holder may be provided with a receiving surface corresponding to the second support portion.

[0009] According to this configuration, when an impact load is input to the cooking appliance, the substrate holder can be brought into contact with the second support portion more reliably.

[0010] The first support portion is disposed on the front side of the casing, and the second support portion is disposed on the rear side of the casing.

[0011] According to this configuration, the second support portion can function as a stopper that prevents the cooking device body from sliding down when the lid is opened or closed, thereby reducing or suppressing the input of impact load to the electronic board while preventing an increase in the number of parts. [Effects of the Invention]

[0012] According to the present invention, when an impact load is input to the cooking appliance, the vibration and impact load transmitted to the electronic board can be suppressed. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] Fig. 1 is a perspective view from above of a rice cooker (heat cooking appliance) 1 according to one embodiment of the present invention, with the lid 30 open and the pot 10 removed. Fig. 2 is a cross-sectional view of the rice cooker 1. Fig. 3 is an exploded perspective view of the rice cooker 1.

[0016] As shown in FIG. 1, the rice cooker 1 comprises a rice cooker body 20 that detachably houses a bottomed cylindrical pot 10 for heating rice, and a lid 30 that is rotatably disposed relative to the rice cooker body 20.

[0017] Referring to Figures 1 and 2, pot 10 is made of a magnetic material and is induction heated by a coil 50 disposed within rice cooker body 20. Pot 10 has bottom 10a, side 10b, and curved portion 10c. Bottom 10a is circular and extends substantially flat in the left-right direction. Side 10b is substantially cylindrical and extends outward in the up-down direction. Curved portion 10c connects bottom 10a and side 10b. Curved portion 10c has a curved surface shape that connects the radially outer end of bottom 10a to the lower end of side 10b.

[0018] The lid body 30 is rotatably attached to the connecting part 48 of the rice cooker body 20, and closes the opening 20a of the rice cooker body 20 when closed on the rice cooker body 20.

[0019] Referring to Figure 3, the lid body 30 has, at its front side, an operation unit 31 for operating the rice cooker 1 and a display unit 32 for displaying the operation status and operating status, and, at its rear side, a steam exhaust port 33 which is the outlet of the exhaust passage.

[0020] The operation unit 31 has multiple operation buttons 31a and an opening button 31b. The operation buttons 31a are buttons for switching the operating state of the rice cooker 1, such as a button to start cooking rice, a button to cancel operation, and a power button. The opening button 31b is a button for opening the lid 30, which is kept closed by a locking mechanism.

[0021] Referring to FIG. 1, an inner lid (not shown) is attached to the inside of lid body 30 to close top opening 10d of pot 10 in a closed state. The inner lid has a sealing member (not shown) that fits tightly against the inner periphery of top opening 10d of pot 10 to close top opening 10d. The inner lid is detachably attached to lid body 30.

[0022] As shown in Figures 2 and 3, the rice cooker body 20 has a casing 40, a housing (protective frame) 50, a coil 61, ferrite (not shown), a ferrite holder 62, a reflector 63, a power supply board 64, an IH board 65, and a cooling fan 66.

[0023] As shown in FIGS. 1 and 2, the casing 40 includes a casing body 41, a shoulder body 47, and a connecting portion .

[0024] 2, 4, and 5, the casing body 41 is a box-shaped resin body and includes a bottom 42, a peripheral wall 43, an opening 44, an intake port 45, and an exhaust port 46.

[0025] The bottom portion 42 has a generally oval shape in a plan view and includes a grip portion 42a, a rib 42b, a protective frame support portion 42c, a main body support structure 42d, and a recess 42n.

[0026] The gripping portions 42a are provided on both sides of the bottom portion 42 and bulge upward. The gripping portions 42a are the parts that are grasped by the user when, for example, moving the rice cooker 1. The ribs 42b are made of protruding pieces that protrude upward from the bottom portion 42, and reinforce the bottom portion 42.

[0027] The protective frame support portions 42c protrude upward (toward the inside of the casing main body 41) from the vicinity of the four corners of the bottom portion 42 to form a conical cylindrical shape. The protective frame 50 is disposed on the upper end of the protective frame support portions 42c (see FIG. 9). In other words, the protective frame support portions 42c hold the protective frame 50 from below.

[0028] The main body support structure 42d protrudes downward (outside the casing main body 41) from near the protective frame support portion 42c and is placed on the mounting table T. This positions the bottom portion 42 at a distance from the mounting table T. The main body support structure 42d is composed of two first main body support portions (first support portions) 42e arranged in front of the casing main body 41 and two second main body support portions (second support portions) 42f arranged in the rear. The first main body support portions 42e have a conical cylindrical shape. The entire first main body support portion 42e is formed integrally with the casing main body 41, and a resin bottom surface 42g abuts against the mounting table T.

[0029] 6, the second main body support portion 42f has a cylindrical portion 42i made of resin and an elastic member 42j. The cylindrical portion 42i protrudes from the lower and upper surfaces of the bottom portion 42. A through-hole 42h is provided in the cylindrical portion 42i. The through-hole 42h extends continuously from the lower surface to the upper surface of the bottom portion 42, vertically penetrating the bottom portion 42. The elastic member 42j is cylindrical and is inserted into the through-hole 42h.

[0030] A circumferential protrusion 42k that protrudes into the through hole 42h is provided on the inner periphery of the through hole 42h, above the bottom 42 of the through hole 42h. The diameter D1 of the elastic member 42j is slightly smaller than the diameter D2 of the through hole 42h. The vertical dimension H1 of the elastic member 42j is larger than the vertical dimension H2 of the through hole 42h. A circumferential groove 42l is provided in the vertical middle portion of the elastic member 42j. A groove 42m that opens toward the tip side is provided on the tip side of the elastic member 42j (the side that is located upper when assembled in the through hole 42h).

[0031] The elastic member 42j is inserted into the through-hole 42 from the bottom 42 side while elastically deforming the tip side. When the circumferential groove 42l engages with the circumferential protrusion 42k, the tip elastically returns to its original position in the radially expanding direction relative to the through-hole 42h, and the elastic member 42j is held within the through-hole 42h. In the assembled state, the elastic member 42 protrudes upward and downward from the through-hole 42h. When the rice cooker 1 is placed on the table T, the elastic member 42j abuts against the table T.

[0032] 4 and 7, recess 42n is provided on the rear side of bottom 42 and is a depression that bulges inward and has a cross-sectional shape of a roughly right-angled triangle when viewed from the side. Recess 42n includes inclined portion 42o made of a flat resin plate, vertical wall portion 42p, and frame portion 42q. Recess 42n is provided with air intake port 45, which will be described in detail later.

[0033] The inclined portion 42o is inclined upward from the front side to the rear side. The inclination angle of the inclined portion 42o with respect to the bottom portion 42 roughly matches the inclination angle of the cooling fan 66 disposed above the inclined portion 42o. The tip of the inclined portion 42o is located between the second support portions 42f. The rear end of the inclined portion 42o is located forward of the peripheral wall portion 43 of the casing main body 41. The inclined portion 42o is inclined upward as it moves away from the bottom portion 42.

[0034] The vertical wall portion 42p extends downward from the rear end of the inclined portion 42o and penetrates the bottom portion 42.

[0038] The multiple slits 45a that make up the intake port 45 are provided in the inclined portion 42o, the vertical wall portion 42p, and the bottom portion 42 that is continuous with the front side of the inclined portion 42o. The multiple slits 46a that make up the exhaust port 46 are provided in the center in the width direction on the front side of the bottom portion 42. The slits 45a, 46a are each narrow grooves that extend in the front-rear direction and are arranged side by side in the front-rear direction and the width direction.

[0039] As shown in Fig. 4, the exhaust port 46 is a ventilation section that spatially connects the inside and outside of the casing main body 41. The exhaust port 46 has a number of slits 46a that penetrate from the inner surface to the outer surface of the casing main body 41. The multiple slits 46a that make up the exhaust port 46 are provided in the center in the width direction on the front side of the bottom 42. The slits 46a are narrow grooves that extend in the front-rear direction and are arranged side by side in both the front-rear direction and the width direction.

[0040] The plurality of slits 46a that make up the exhaust port 46 are provided in the center in the width direction on the front side of the bottom 42. The slits 45a, 46a are narrow grooves that extend in the front-rear direction and are arranged side by side in the front-rear direction and the width direction.

[0041] 1, shoulder 47 is made of a synthetic resin material and is attached from above to cover opening 44 of casing body 41. An engagement hole 47c is provided on the front side of shoulder 47 to engage with locking claw 34 provided on the front part of lid 30.

[0042] Fig. 8 is a perspective view of shoulder body 47 as seen from below. Fig. 9 is a side cross-sectional view of support structure 42d of rice cooker 1, with lid body 30 and some of the components inside the casing not shown.

[0043] 8 and 9, a plurality of bosses 47a protrude downward from the underside of the shoulder body 47 at positions corresponding to the protective frame support portions 42c of the bottom portion 42. The protective frame 50 is clamped between the bosses 47a and the protective frame support portions 42c and fastened together. This rigidly connects the casing main body 41, shoulder body 47, and protective frame 50. Bosses 47b are provided on the underside of the shoulder body 47 for suspending and fixing a second board holder 71 that houses an IH board 65.

[0044] The connecting portion 48 is provided on the rear side of the shoulder body 47 and is a hinge portion for rotatably mounting the cover body 30. The connecting portion 48 is fitted into the notch portion 43d of the casing main body 41 and is fixed to the shoulder body 47.

[0045] Referring to Figure 9, protective frame 50 is made of resin and has a saucer shape. Protective frame 50 is located below shoulder 47 within casing body 41. Pot 10 is placed within protective frame 50. Inner body 51 is clamped above protective frame 50 and below shoulder 47. Protective frame 50 has receiving portion 50a that protrudes outward at a position corresponding to protective frame support portion 42c of bottom 42.

[0046] A substrate mounting portion 52 that forms part of a first substrate holder 91 is formed on the front side of the protective frame 50. A substrate cover 53 is attached to the substrate mounting portion 52 and covers a power supply substrate (not shown). A second substrate holder 71 is attached to the rear side of the protective frame 50.

[0047] As shown in FIGS. 2 and 3, a coil 61, a ferrite holder 62, a reflector 63, a power supply board 64, an IH board 65, and a cooling fan 66 are housed between the casing 40 and the protective frame 50.

[0048] Coil 61 is positioned below protective frame 50 and induction heats pot 10. Ferrite holder 62 is positioned further below coil 61 and holds ferrite that converges the magnetic flux from coil 61. Reflector 63 is positioned below ferrite holder 62 and shields the high-frequency magnetic field generated by coil 61.

[0049] 3, the power supply board 64 is disposed in a board holder 27c provided on the front side of the protective frame 50. A cord reel capable of winding up a cord having a power plug is electrically connected to the power supply board 64.

[0050] As shown in FIG. 9 , the IH board 65 is disposed in a second board holder 71 provided on the rear side of the protective frame 50. A control unit (not shown) that controls electrical components including the coil 61 is mounted on the IH board 65. The cooling fan 66 is disposed below the IH board 65 on the rear side of the protective frame 50. The cooling fan 66 takes in outside air into the casing 40 to cool the coil 61, the IH board 65, and the like. In this embodiment, the cooling fan 66 is attached integrally to the second board holder 71.

[0051] Figure 10 is a perspective view of the second substrate holder 71 to which the cooling fan 66 is integrally attached. Figure 11 is an exploded perspective view of the second substrate holder 71 to which the cooling fan 46 is integrally attached. Only the frame of the cooling fan 66 is shown in Figures 10 and 11.

[0052] 10 and 11, the second substrate holder 71 is made of resin. An IH substrate 65, a heat sink 67, and a cooling fan 66 are attached to the second substrate holder 71. The second substrate holder 71 mounts the IH substrate 65 substantially vertically and the cooling fan 66 at an angle, and these are fixed integrally to the shoulder body 47.

[0053] The heat sink 67 is disposed near the heat-generating electronic components on the IH board 65 and cools them by absorbing the heat from the surrounding area. The fins 67a of the heat sink 67 are arranged side by side and extend in the vertical direction.

[0054] The second board holder 71 includes a first cover 72, a second cover 73, and a fan holding portion 74. The first cover 72 includes a flat front wall portion 72a disposed on the front side and extending along the vertical and horizontal planes (the shape of the induction board 65), a first connecting wall 72b extending rearward from the periphery of the front wall portion 72a, and a bracket portion 72c for fixing the second board holder 71 to the shoulder body. A first notch portion 72d is formed in the center and lower part of the front wall portion 72a in the width direction. A pair of protrusions 72e protruding forward from the lower edge of the front wall portion 72a are provided on both ends of the first notch portion 72d.

[0055] The first connecting wall 72b has a first upper wall 72f, a pair of first side walls 72g, a first lower wall 72h, a pair of notch side walls 72i, and a notch upper wall 72j. The first upper wall 72f extends rearward from the upper edge of the front wall 72a, the pair of first side walls 72g extend rearward from both side edges of the front wall 72a, and the first lower wall 72h extends rearward from the lower edge of the front wall 72a excluding the first notch 72d. The pair of notch side walls 72i extend rearward from both edge edges of the notch, and the notch upper wall 72j extends rearward from the upper edge of the first notch 72d.

[0056] The second cover 73 is disposed rearward of the first cover 72. The second cover 73 has a base wall 73a extending along planes in the up-down and left-right directions, a bulging portion 73b formed by bulging the upper portion of the base wall 73a rearward, a second connecting wall 73c extending forward from the periphery of the base wall 73a, and a bracket portion 73d for fixing the second substrate holder 71 to the shoulder body 47. A second notch 73e is formed in the center and below the width of the base wall 73a at a widthwise position corresponding to the first notch 72d. The height of the second notch 73e is greater than the height of the first notch 72d.

[0057] The second connecting wall 73c has a second upper wall 73f, a pair of second side walls 73g, and a second lower wall 73h. The second upper wall 73f extends forward from the upper edge of the base wall portion 73a, and the pair of second side walls 73g extend forward from both side edges of the base wall portion 73a. The second lower wall 73h extends forward from the lower edge excluding the second cutout portion 73e. The second lower wall 73h is continuous with the bulging portion 73b. No connecting wall is provided at the lower edge of the second cutout portion 73e.

[0058] The fan holding portion 74 is provided on the inside of both sides of the second cutout portion 73e. The fan holding portion 74 is a pair of plate members 74a extending in the front-rear direction. The fan holding portion 74 is formed integrally with the second cover 73. The fan holding portion 74 slopes downward from the upper end of the second cutout portion 73e toward the front. A plurality of inner protrusions 74b protruding inward are provided at the tip ends of the opposing surfaces of the fan holding portion 74. An engagement portion 74c that engages with the cooling fan is provided at the rear end of the opposing surfaces of the fan holding portion 74. A pair of protrusions 74d protruding outward in the width direction are provided on the outer surface opposite the opposing surfaces at the tip side of the fan holding portion 74. Each protrusion 74d is arranged from above on each of the protrusions 72e of the first cover 72.

[0059] Referring to Figure 10, by connecting the first cover 72 and the second cover 73 at the engagement portions provided on the first and second connecting walls 72b, 73c, a storage space is formed to store the IH board 65 and the heat sink 67, and the tip of the fan holding portion 74 penetrates the first cutout portion 72d in the front-to-rear direction.

[0060] An induction board 65 is housed in the first cover 72, a heat sink 67 is stored in the bulging portion of the second cover 73, and a cooling fan 66 is held in the fan holding portion 74. The cooling fan 66 is held in a state inclined upward and rearward along the slope of the fan holding portion 74 by a plurality of inner protrusions 74b and engagement portions 74c.

[0061] When the cooling fan 27 is driven, ambient air is sucked in through an air intake 45 formed on the rear side of the bottom 42 of the casing main body 41 and sent to the IH board 65 and the heat sink 67 .

[0062] FIG. 12 is a cross-sectional view seen from the front, showing a state in which the second substrate holder 71 is attached to the shoulder body 47. As shown in FIG.

[0063] The second substrate holder 71 is attached to the shoulder body 47 by engaging the bracket portions 72c and 73d with the boss portion 43b of the shoulder body 47 and fixing them by, for example, screws. In other words, the second substrate holder 71 is rigidly connected to the casing 40 at the upper portion.

[0064] 6 and 12, when attached to the shoulder 47, the lower part of the second substrate holder 71 is spaced (floating) from the bottom 42 of the casing main body 41 or abuts against the elastic member 42j of the second main body support part 42f. More specifically, the lower surface of the first lower wall 72h of the second substrate holder 71 and the tip of the elastic member 42 are disposed opposite each other, and the lower surface of the first lower wall 72h forms a receiving surface that receives the tip of the elastic member. In other words, the first lower wall 72h and the second main body support part 42f are spaced apart or abut against each other.

[0065] 6 and 7, the gap S1 between the first lower wall 72h and the elastic member 42j is set to be smaller than the shortest distance S2 between the second substrate holder 71 and the casing main body 41. In this embodiment, the cooling fan 66 is integrally attached to the second substrate holder 71 and is inclined downward toward the front, so the shortest distance S2 between the second substrate holder 71 and the casing main body 41 is the vertical gap between the upper surface of the bottom 42 and a corner 66a on the lower surface side of the frame surrounding the cooling fan 66.

[0066] The rice cooker 1 configured in this manner has the following features.

[0067] An impact load input to the rice cooker 1 is transmitted to the second substrate holder 71 via the first support portion 42e, which is made of a rigid body (made of resin), and the casing 40. When the impact load is transmitted to the second substrate holder 71, the second substrate holder 71 abuts against the second support portion 42f, which is made of an elastic body, thereby attenuating the impact load input to the second substrate holder 71. In this embodiment, the second substrate holder 71 and the inclined portion 42o of the resin casing main body 41 are arranged in close proximity. Therefore, when an impact load is input to the rice cooker 1, the substrate holder (more specifically, the fan holding portion 74) comes into contact with the inclined portion 42, and the impact load may be input to the second substrate holder 71. In response to this, the load input from the inclined portion 42o can be suppressed by abutting the first lower wall 72h of the substrate holder against the second support portion 42f.

[0068] The second substrate holder 71 is provided with a receiving surface (first lower wall 72h) corresponding to the second support portion 42f, so that when an impact load is input to the rice cooker 1, the second substrate holder 71 can be more reliably abutted against the second support portion 42f.

[0069] By taking in outside air through an air intake located close to second board holder 71, the electronic board inside second board holder 71 is efficiently cooled. Meanwhile, when an impact load is input to rice cooker 1, the board holder comes into contact with second support portion 42j, thereby suppressing the input load to the electronic board due to contact between second board holder 71 and the air intake.

[0070] The separation distance S1 between the second substrate holder 71 and the second support portion 42f is set to be larger than the separation distance between the second substrate holder 71 or the case of the cooling fan 66 held by the second substrate holder 71 and the air intake port 45, so that contact between the second substrate holder 71 and the air intake port 45 can be more reliably avoided.

[0071] Because the cooling fan 46 is attached integrally to the second board holder 71, the cooling fan 46 and the second board holder 71 can be brought close to each other, enabling efficient cooling of the induction board (electronic board) 65. On the other hand, if the cooling fan 46 is positioned below the electronic board 65 in order to cool the electronic board 65, the gap between the air intake 45 and the second board holder 71 is reduced, and the effect of providing the second support structure 42d becomes more pronounced.

[0072] When the release button 31b is pressed to release the locking mechanism, the rice cooker 1 may slide backward as the lid 30 rotates around the connection part. To address this issue, the second support part 42f, made of an elastic material, is positioned on the rear side of the casing, where it functions as a stopper that prevents the rice cooker 1 from sliding backward when the lid is opened or closed. As a result, the impact load on the electronic board can be attenuated or suppressed while minimizing an increase in the number of parts.

[0073] In the above embodiment, a configuration has been described in which the cooling fan 66 is integrally attached to the second substrate holder 71, but this is not limiting, and the cooling fan 66 may not be attached to the second substrate holder 71. Even in such a case, the second substrate holder 71 and the casing 40 may come into contact with each other in the portion where they are close to each other, which may result in an impact load being input to the IH substrate 65. However, by bringing the elastic member 42j of the second support portion 42f into contact with the second substrate holder 71, the input of the impact load to the IH substrate 65 can be attenuated or suppressed.

[0074] The cooking device 1 of the present invention is not limited to the configuration of the above-described embodiment, and various modifications are possible. [Explanation of symbols]
