Japanese Patent Application Publication No. 2004-071213

  By the way, in such a microwave oven, a configuration may be adopted in which the stirring container is formed of a metal material. When this stirring container is installed in the installation part made of metal, such as the bottom of the cooking chamber, when a high frequency is introduced into the cooking chamber, it is introduced between the stirring container and the installation part contacting the stirring container. Due to the influence of the high frequency, a potential difference due to charging may be generated, and spark may occur.

  In view of such a subject, the present invention is a cooking-by-heating machine which can heat a to-be-cooked thing by high frequency, and when a container which has a stirring function is formed with metal material, generation of spark between such a container and a cooking chamber The purpose is to prevent.

The heating cooker according to the main aspect of the present invention comprises a cooking chamber for containing food to be cooked, a high frequency supply unit for supplying a high frequency into the cooking chamber, and a metal installation unit provided on the bottom of the cooking chamber. A contact portion placed on and in contact with the installation portion is made of metal and has a container having a stirring blade, a power supply unit for supplying power for driving the blade, and the power supply unit A control unit for operating the high-frequency supply unit while holding the container, and a fixing unit for detachably fixing the container in the cooking chamber so that the contact unit does not move away from the installation unit.

  According to the above configuration, the contact surfaces of the contact portion and the installation portion can be kept in close contact with each other, so when heating by the high frequency is performed, the influence of the high frequency between the container and the installation portion There is no potential difference. Therefore, it can prevent that a spark arises between a container and a cooking chamber.

  The heating cooker which concerns on this aspect WHEREIN: The said fixing | fixed part may be set as the structure which gives the force in the direction which the said contact part contacts the said installation part to the said container.

  For example, the contact portion is provided at the bottom of the container body and includes a pedestal that supports the container body, and the pedestal is formed with a projection that protrudes outward. The fixing portion is provided on the installation portion, and is engaged with the projection portion so as to overlap above the projection when the pedestal is placed on the installation portion and horizontally rotated. The engagement portion may allow the root portion fixed to the installation portion to bend upward. When the protrusion engages with the engaging portion, the engaging portion is pushed upward, the root portion is bent, and a pressing force is applied from the engaging portion to the protrusion.

  Further, as described above, in the case where the container is provided with the shield wall portion, and the container is not installed in the cooking chamber, the lower surface of the shield wall portion is the installation of the contact portion. It can be made lower than the contact surface with the part. In this case, the contact surface of the installation unit with the contact unit may be higher than the bottom surface of the cooking chamber around the installation unit. Thereby, when the container is installed in the cooking chamber and the contact surfaces of the contact portion and the installation portion are in contact with each other, between the shield wall and the bottom surface of the cooking chamber around the installation portion , A gap is formed so as not to cause sparks.

If such configuration as is, when placed on the mounting table such as a table with the container was taken out from the cooking device, it is possible to support the container body in the shield wall, it is placed in the mounting base of the container stably it can. Furthermore, when the container is placed in the cooking chamber, sparks can be prevented from occurring between the shield wall and the bottom of the cooking chamber.

  The heating cooker which concerns on this aspect WHEREIN: The structure further equipped with the hot-air supply part which supplies the hot air which uses the flame of gas as a heat source to the said cooking chamber may be taken. In this case, the control unit operates the high frequency supply unit and the hot air supply unit while operating the power supply unit.

  According to the above configuration, since both hot air and high frequency are supplied into the cooking chamber at the time of stirring by the container, the heating effect of the food in the stirring container can be enhanced, and the cooking time can be shortened. Moreover, since the hot air is supplied from the hot air supply unit using the gas flame as the heat source, even when both the hot air and the high frequency are supplied, it is not necessary to care about the electric capacity.

  As described above, according to the present invention, in a heating cooker capable of heating a food to be cooked by high frequency, when a container having a stirring function is formed of a metal material, a spark is generated between the container and the cooking chamber Can be prevented.

  Next, the configuration of the stirring container 70 will be described. FIG. 4 and FIG. 5 are diagrams showing the configuration of the stirring container 70. FIG. 4 (a) is a plan view of the stirring container 70, and FIG. 4 (b) is a bottom view of the stirring container 70. As shown in FIG. FIG. 5 is a front sectional view of the stirring container 70. As shown in FIG. FIG. 5 shows a state in which the stirring container 70 is placed on a table such as a table.

  Agitation vessel 70 includes vessel body 210, pedestal 220, shield wall 230, blade shaft 240, agitation blade 250, and input cam 260.

  The container body 210 is a bottom deep round pot formed of a metal material such as aluminum. The shape of the container body 210 is not limited to the shape of a round pot, and may be any shape.

  The pedestal 220 has a cylindrical shape with the top closed and the bottom open, and supports the container body 210. The pedestal 220 is formed of a metal material such as aluminum. At the lower end of the outer peripheral surface of the pedestal 220, a plurality of claws 221 are formed at substantially equal intervals so as to protrude outward. The height of the claw portion 221 is equal to the clearance S between the center of the bottom surface 131a of the engagement claw portion 131 and the bottom surface 121a of the concave portion 121 of the installation stand 120 shown in FIG. 3B.

  The shield wall 230 has a cylindrical shape and is provided so as to surround the pedestal 220. The shield wall 230 is integrally formed with the pedestal 220 by a metal material. The lower end surface 230 a of the shield wall 230 is formed in an arc shape and is lower than the lower end surface 220 a of the pedestal 220. For this reason, as shown in FIG. 5, when the stirring container 70 is taken out from the heating cooker 1 and placed on a mounting table such as a table, the container body 210 is supported by the shield wall 230 having a larger outer diameter than the pedestal 220. It can be done. Thus, the stirring container 70 can be stably placed on the mounting table.

  The pedestal 220 integrally formed with the shield wall 230 is fixed to the bottom of the container body 210 by a screw 270. A slide bearing 222 is provided on the top of the pedestal 220, and the pedestal 220 rotatably supports the blade shaft 240 by the slide bearing 222.

  The stirring blade 250 includes a boss portion 251 and a blade 252 extending outward from the boss portion 251, and the boss portion 251 is mounted on the tip end portion of the wing shaft 240. The input cam 260 is disposed in the pedestal 220 and fixed to the lower portion of the wing shaft 240. The input cam 260 is formed with an input blade 261 extending downward on both sides.

  FIG. 6 is a view for explaining the installation of the stirring container 70 on the installation table 120 provided on the bottom of the cooking chamber 20. As shown in FIG. 6 (a) shows a state before the pedestal 220 of the agitation container 70 is fixed to the installation table 120, and FIGS. 6 (b) and 6 (c) show the pedestal 220 of the agitation container 70 as the installation pedestal 120. Indicates a fixed state. 6 (a) and 6 (b), a plan view cut horizontally in the middle of the pedestal 220 is used so that the mounting operation on the installation table 120 can be easily understood.

  When the stirring container 70 is mounted on the installation table 120, first, as shown in FIG. 6A, the claws 221 of the pedestal 220 do not hit the engagement claws 131 of the fixture 130. The pedestal 220 is accommodated in the recess 121 of the installation table 120. Thereafter, as shown in FIG. 6B, the stirring container 70 is horizontally rotated clockwise to a position where the engaging claws 131 of the fixing tool 130 overlap the claws 221 of the pedestal 220. By the engagement between the claws 221 and the engagement claws 131, the stirring container 70 does not come off from the installation stand 120.

  Here, the height of the claw portion 221 is larger than the narrowest gap between the engagement claw portion 131 and the bottom surface of the concave portion 121. In addition, the engagement claw portion 131 can be slightly bent upward at the root portion. For this reason, as shown in FIG. 6C, in a state where the claws 221 completely overlap the engagement claws 131, the claws 221 slightly push up the engagement claws 131, and are bent upward. As shown by the thick arrow in the figure, a force is applied to the claw portion 221 from the downward engaging claw portion 131. Thereby, the adhesion between the lower end surface 220a of the pedestal 220 and the bottom surface 121a of the recess 121 of the installation stand 120, that is, the contact surfaces of the pedestal 220 and the recess 121 is improved.

  As shown in FIG. 6C, when the stirring container 70 is mounted on the installation table 120, the gap D between the lower end surface 230a of the shield wall 230 and the bottom of the cooking chamber 20 around the installation table 120. Will occur. The gap D is set to a value at which sparks do not occur between the bottom surface 230 a of the shield wall 230 and the bottom surface of the cooking chamber 20 even if a high frequency is concentrated. The height H of the bottom surface 121 a of the recess 121 from the bottom surface of the cooking chamber 20 is set so that a sufficient gap D can be secured between the shield wall 230 and the bottom surface of the cooking chamber 20. Further, since the lower end surface 230a of the shield wall portion 230 has an arc shape (R shape), it is difficult for the high frequency to be concentrated on the lower end surface 230a.

  When the stirring container 70 is mounted on the installation table 120, the input blade 261 of the input cam 260 engages with the output blade 152 of the output cam 150 inside the pedestal 220, and the blade shaft 240 of the stirring container 70 is a drive shaft It is connected to 110.

  When the drive motor 160 is driven, the rotation of the drive motor 160 is transmitted to the drive shaft 110 by the transmission mechanism unit 170, and the drive shaft 110 rotates at a rotational speed reduced according to the reduction ratio by the transmission mechanism unit 170. The blade shaft 240 connected to the drive shaft 110 rotates, and the stirring blade 250 rotates in the container body 210. By the rotation of the stirring blade 250, the food contained in the stirring container 70 is stirred.

  Simultaneously with the stirring of the food to be cooked in the stirring container 70, the high frequency supply unit 40 and the hot air supply unit 30 operate to supply the high frequency and the hot air into the cooking chamber 20. The to-be-cooked material in the stirring container 70 is heated by a high frequency and a hot air. Here, as shown in FIG. 6C, the high frequency M supplied into the cooking chamber 20 is shielded by the shield wall 230, so that the high frequency M is prevented from entering the inside of the shield wall 230. .

  FIG. 7 is a block diagram showing the configuration of the heating cooker 1.

  The heating cooker 1 includes a control unit 300, a temperature sensor 301, and a weight sensor 302 in addition to the components described above. The temperature sensor 301 detects the temperature in the cooking chamber 20. The weight sensor 302 detects the weight of the food stored in the cooking chamber 20. The control unit 300 drives the gas burner 31 and the blower fan 32 of the hot air supply unit 30, the magnetron 41 of the high frequency supply unit 40, and the drive device 50 based on the inputs from the operation panel 12, the temperature sensor 301, the weight sensor 302 and the like. It controls the operation of the motor 160 and the like.

  When the automatic cooking course is selected by the operation panel 12 and the start operation is performed, the control unit 300 starts the operation of the automatic cooking course and operates the drive motor 160 to operate the high frequency supply unit 40 (magnetron 41) and the hot air The supply unit 30 (the gas burner 31 and the blower fan 32) is operated. As described above, the food is stirred and heated in the stirring vessel 70.

<Effect of the embodiment>
As mentioned above, according to this embodiment, the following effects are produced.

  Since the pedestal portion 220 of the agitation container 70 is fixed by the fixture 130 so as not to be separated upward from the installation table 120, the contact surfaces of the pedestal portion 220 and the installation pedestal 120 are firmly secured when the stirring operation is performed. It can be kept in close contact. Thereby, when heating by a high frequency is performed, a potential difference due to the influence of the high frequency does not occur between the pedestal portion 220 and the installation stand 120. Therefore, it can prevent that a spark arises between stirring container 70 and cooking chamber 20.

  Further, in a state where the pedestal 220 is fixed to the fixture 130, a force for pressing downward from the engaging claws 131 of the fixture 130 to the claws 221 of the pedestal 220 is applied. The adhesion between the contact surfaces of the recess 121 is improved. Furthermore, in the engagement claw portion 131, the bottom surface 131a is inclined in a direction in which the stirring blade 250 is tightened when the stirring blade 250 is rotated, and a force works to make the contact surfaces adhere more strongly during the cooking operation. Thus, the spark preventing effect between the stirring container 70 and the cooking chamber 20 is further enhanced.

  Furthermore, since the penetration of the high frequency wave to the inside of the shield wall 230 is suppressed, the high frequency wave can be prevented from being concentrated on the pedestal portion 220, particularly the lower end portion (contact surface portion) of the pedestal portion 220. As a result, the spark preventing effect between the stirring container 70 and the cooking chamber 20 is further enhanced.

  Furthermore, since both hot air and high frequency are supplied into the cooking chamber 20 at the time of stirring by the stirring container 70, the heating effect of the food in the stirring container 70 can be enhanced, and the cooking time can be shortened. Moreover, since the hot air is supplied from the hot air supply unit 30 using the gas flame as the heat source, there is no need to worry about the electric capacity even when both the hot air and the high frequency are supplied.

The high frequency M1 (dotted line arrow in FIG. 8) which tries to enter the inside of the shield wall 280 from the gap between the shield wall 280 and the bottom of the cooking chamber 20 is the high frequency M2 returned from the inside of the periodic structure 281 (figure 8), and interferes with the high frequency M2 whose wavelength is shifted by half a wavelength from the high frequency M1 to be intruded. As a result, the high frequency M1 to be invaded is attenuated.
