Description

  The present invention relates to an induction heating cooker including a heating coil for induction heating and a roaster section in a main body.

  In many cases, the induction heating cooker has a roaster section that performs grilling of fish and the like using a heater. Since the exhaust in the roaster section is hot, it is generally exhausted upward from the back side of the top plate in order to avoid exhausting the user.

  Examples of this type of induction heating cooker include Patent Document 1 and Patent Document 2.

Japanese Patent Laid-Open No. 11-87037 JP 2002-93559 A

  In the above conventional configuration, as shown in Patent Document 1, in the case of exhausting upward from the rear side of the top plate, the smoke containing the vapor generated inside the roaster passes through the exhaust passage on the rear side of the main body, After being exhausted upward from the side, it is easy to rise along the kitchen wall behind the induction heating cooker body due to diffusion, so that smoke stains stick to the kitchen wall or the kitchen wall condenses and drops dripping Drops and mold occurred.

  In order to solve the above problem, as shown in Patent Document 2, a partition plate that is inclined upward and forward is provided on the upper surface of the exhaust port, and an opening is provided in front of the partition plate to generate steam generated in the roaster. However, in this structure, a partition plate or an opening is formed on the upper surface of the induction heating cooker body. Protrusions and dents are generated, and the convenience of being able to freely move the pan on the top plate, which is a major advantage of induction heating cookers, and the cleanability of being easy to clean due to the full flatness are impaired. There was a problem.

  The present invention addresses the above problems and suppresses the sticking and condensation of water vapor and oil smoke generated on roaster cooking to the kitchen wall while retaining the advantages of full top and bottom of the induction heating cooker. It is.

  In claim 1 of the present invention, the main body of the induction heating cooker is provided with a roaster unit, a heating coil for induction heating, and a control unit unit for controlling these heating means.

  According to a second aspect of the present invention, the outlet outlet for exhausting the cooling air is provided on a stay for fixing the exhaust duct to the induction heating cooker body.

  According to a third aspect of the present invention, the outlet of the exhaust duct is formed by bending a metal member.

  According to the present invention, since no protrusions or dents are formed on the upper surface of the induction heating cooker body, the convenience that the pan can be freely moved on the top plate, which is a great advantage of the induction heating cooker, remains as it is. Can be held.

  In addition, while maintaining the full flatness of the top surface of the induction heating cooker main body, it is possible to suppress the sticking and condensation of water vapor and oily smoke that occur when roaster cooking is performed on the kitchen wall, making cleaning easy and clean There is an advantage that it is good.

That is, the distance L1 between the top plate 112 and the front of the outlet 401 is set to be larger than the distance L2 between the top plate 112 and the rear of the outlet 401.

Further, between the rear side of the exhaust duct 204 and the back surface of the main body 101, the heating coils 105 to 105 are provided.
A flow path 405 for exhausting the cooling air 404 after cooling 107 and the like through the outlet 402 and the exhaust port 110 is formed.

  In FIGS. 5 and 6, 505 is a stay for fixing the exhaust duct 204 to the rear cover 506 of the main body 101, and 501 and 502 are cooling air exhaust ports provided in the stay 505, at the exhaust outlet portion of the flow path 405. It is formed and continues to the exhaust port 110. Reference numerals 503 and 504 denote cooling air exhaust ports for discharging exhaust air after cooling each part by the cooling fan 301, and reference numeral 506 denotes a rear cover of the induction heating cooker body 101.

  FIG. 8 is an external perspective view of the exhaust port cover 111. The exhaust port cover 111 is for preventing the cooking material or the like from dropping into the exhaust port 110, and a plurality of vent holes 801 are formed and set so as to be detachable so as to cover the exhaust port 110.

  Next, a case where the roasting operation is performed using the roaster unit 102 will be described.

  When the user puts food such as fish 205 on the grill net 201 of the roaster unit 102 and operates the operation unit 103, the upper heater 202 and the lower heater 203 start energization.

  When the inside of the roaster case 206 reaches a high temperature due to this fish roasting operation, the air inside rises and flows into the exhaust duct 204 through the opening 207. There is an air inlet on the front side of the roaster case 206, and an air flow is generated in the roaster case 206 by the principle of negative pressure suction. Water vapor and oil smoke 403 generated inside the roaster by riding this air flow pass through the exhaust duct 204 and are exhausted from the exhaust outlet 401.

  In general, the outlet of the exhaust duct 204 has a large resistance to the flow because the flow path rapidly expands. Therefore, as described above, the outlet 401 of the exhaust duct 204 is formed obliquely downward so that the front side is lowered with respect to the main body 101, thereby increasing the area of the outlet 401 and reducing this resistance. It is advantageous.

  Further, since the distance L1 between the top plate 112 and the front of the outlet 401 is larger than the distance L2 between the top plate 112 and the rear of the outlet 401, the water vapor and the oil smoke 403 are exhausted forward.

  Thereby, it is possible to prevent water vapor or oily smoke generated during roaster cooking from sticking to the kitchen wall, condensation on the kitchen wall, dripping or dropping, and generation of mold.

  Further, when the cooling fan 301 is driven even when only the roaster section 102 is used, the cooling air 404 blows out from the rear of the exhaust duct outlet 401, so that this air acts as an air curtain and performs roaster cooking. It has the effect of suppressing the water vapor and oily smoke generated when it comes into contact with the kitchen wall.

  In addition, in an induction heating cooker equipped with a catalyst in the exhaust path to deodorize odors and oily smoke generated when roaster cooking is performed, and further provided with an exhaust fan in the exhaust duct for forced exhaust, Since the kitchen wall is contaminated and dewed, the present invention is also effective.

  Further, as shown in the second embodiment of FIG. 7, the wall 701 behind the outlet 401 is inclined forward, so that the exhaust 702 from the roaster portion 102 further changes its direction forward and comes into contact with the kitchen wall. There is an effect to suppress this.

  Furthermore, the same effect can be obtained even if a diagonally downward louver is provided below the exhaust port cover 111 shown in FIG.

  Further, since the wall 701 is formed by bending a sheet metal, the end surface has a curvature, and even if the user puts his hand into the exhaust port 110 with the upper body from which the exhaust port cover 111 is removed, the wall 701 is injured. There is little fear to do.

  In addition, when the distance L2 between the exhaust port cover 111 and the outlet 401 is long, water vapor and oil smoke exhausted from the outlet 401 with an oblique directionality are diffused by the plurality of ventilation holes 801, and the directionality is lost. It is desirable to configure L2 as short as possible.

It is an external appearance perspective view of the induction heating cooking appliance by this invention. It is AA sectional drawing of FIG. It is BB sectional drawing of FIG. It is an expanded sectional view near the exhaust port according to the present invention. It is an enlarged top view of an exhaust port vicinity in the state which removed the exhaust port cover of the induction heating cooking appliance by this invention. It is an expansion perspective view of the exhaust port vicinity in the state which removed the exhaust port cover of the induction heating cooking appliance by this invention. It is an expanded sectional view near the exhaust port according to the second embodiment of the present invention. It is an external appearance perspective view of the exhaust port cover by this invention.
