Description

  The present invention relates to a cooking device that cooks an object to be heated placed on a placing plate.

  In general, a heating cooker that heats and cooks an object to be heated in a heating chamber such as a convection oven or a steam oven by hot air circulation has a fan for forcibly circulating hot air in the heating chamber. The fan speeds up cooking and makes the temperature distribution in the cabinet uniform, improving the baking performance. In addition to the oven cooking function, there is also a cooking device having an electromagnetic heating cooking function, a dielectric heating cooking function, a steam cooking function, an oven / electromagnetic heating / dielectric heating / steam combined cooking function, and the like.

  FIG. 11 is a front view of a conventional cooking device, FIG. 12 is a side sectional view of the conventional cooking device, and FIG. 13 is a plan view of a mounting plate provided with a conventional hot air circulation function.

  As shown in FIGS. 11 and 12, the conventional cooking device includes a box body 11 that has been subjected to heat insulation, a heating chamber 12 that is housed in the box body 11 and that contains a heated object S, a sheathed heater, and the like. The annular heater 13, the blower 20 for blowing out hot air heated by the heater 13, the heat insulating door 15 that freely opens and closes the front opening of the heating cabinet 12, and instructions from the user are input. The operation part 16 and the control part (not shown) which controls the heater 13 and the air blower 20 are provided. The heating chamber 12 has two side walls 31, a back wall 32, a top wall and a bottom wall, and a fan casing 21 of the blower 20 is attached to the back side of the back wall 32. Two support portions 19 that support the mounting tray 40 are formed on the side wall 31 in the vertical direction.

  The blower 20 includes a centrifugal fan 22, a drive motor 23 that drives the centrifugal fan 22, and a fan casing 21 that supports the drive motor 23 while supporting the centrifugal fan 22. A suction port 17 is formed at the center of the back wall 32 of the heating chamber 12, and air outlets 18 b are formed at a plurality of locations so as to surround the suction port 17. The air inlet 17 and the air outlet 18b communicate with each other through a fan casing 21.

  As shown in FIG. 11, the air outlet 18 b is configured to suppress the heating unevenness of the object to be heated S, that is, so as to appropriately heat the object to be heated S according to the mounting position of the mounting plate 40. They are arranged concentrically around the centrifugal fan 22.

  In the heating cooker having such a structure, when the placing plate 40 on which the article to be heated S is placed is placed in the heating chamber 12 and the cooking content is input from the operation unit 16, the control unit is input from the operation unit 16. Based on the received instructions, the heater 13, the blower 20, and the like are driven and controlled to start cooking the object S to be heated.

  The air blown out by the centrifugal fan 22 is heated by the heater 13 to become hot air, and the hot air is blown out from the air outlet 18b. As shown by the arrow in FIG. 12, the hot air blown out from the outlet 18 b flows toward the front surface in the heating chamber 12, hits the heat insulating door 15, changes the direction of the flow, concentrates in the center, and the suction force of the blower 30. Is sucked from the suction port 17. However, depending on the positional relationship between the mounting tray 40 and the air outlet 18b, hot air may not be uniformly applied to the object to be heated S, resulting in uneven heating.

  Therefore, in Patent Document 1, a variable member for guiding the hot air from the centrifugal fan to the outlet is provided by stacking two stages of the mounting tray in the heating chamber, and the flow of the hot air in the rotational direction side is defined. The air volume is made uniform by increasing the volume of hot air. Therefore, in patent document 1, the speed of cooking can be speeded up and the temperature distribution in the heating chamber can be made uniform, and the performance of cooking can be improved.

Moreover, in patent document 2, as shown in FIG. 13, when the protrusion 45 is provided in the edge part 42 of the mounting tray 40 and the mounting tray 40 is mounted in a heating chamber, the protrusion 45 causes the back wall of the heating chamber. A gap is formed between the hot plate and the hot plate, so that hot air can be circulated through the upper and lower spaces of the mounting plate 40 mounted vertically.
Japanese Patent Publication No. 07-111256 (paragraphs 0010 to 0011, FIG. 1) JP 2003-130356 A (paragraphs 0020 to 0022, FIG. 1)

  However, in the conventional cooking device including Patent Documents 1 and 2, the position of the mounting dish is limited according to the blowout port, and the position of the mounting dish can be changed according to the size of the object to be heated. Can not. Moreover, the contact condition of hot air differs between a tall object to be heated and a short object to be heated. For this reason, a tall object to be heated such as a butter roll has a problem that uneven burning such as scorching occurs because hot air concentrates on the upper part protruding upward from the mounting plate. On the other hand, a short object to be heated such as a cookie has a problem that it takes time for cooking because hot air is difficult to hit directly. Furthermore, there is a problem that cooling air from a cooling fan that cools the electrical components is blown into the heating chamber from an opening provided on the side wall in the heating chamber, and blown to the object to be heated, causing uneven baking.

  In view of the above, an object of the present invention is to provide a cooking device that can cook an object to be heated without unevenness regardless of the mounting position of the mounting plate.

  The present invention intends to solve the above problem by providing a wind direction varying means on a mounting tray that is detachably stored in a heating cabinet. That is, the present invention is a mounting tray that is detachably stored in a heating chamber having a hot air outlet, and is blown out from the outlet to the object to be heated placed on the mounting portion. The present invention is characterized in that a wind direction varying means for restricting the flow of hot air is provided.

  The wind direction varying means acts to change the direction of flow with respect to the hot air, weaken or disperse the wind, in order to prevent the hot air from flowing directly onto the mounting portion. For example, the wind direction varying means is a variable member that changes the flow of hot air so that hot air blown out from the air outlet does not directly hit the object to be heated. The variable member has a guide surface that guides hot air to the bottom surface side of the mounting portion. A variable member is arrange | positioned in the position which directly hits the hot air blown off from the blower outlet formed in the heating chamber, for example, the position facing a blower outlet, when a mounting plate is accommodated in a heating cabinet.

  The hot air hits the guide surface formed on the variable member, and the flowing direction is restricted to the bottom surface side of the mounting portion. Therefore, since hot air does not directly hit the object to be heated, it is possible to suppress burning unevenness without burning. The variable member is not limited to a shape that guides the hot air to the bottom surface side of the placement unit, but may be regulated so that the hot air flows to the side surface side, the top surface side, or the like of the placement unit.

  In addition, the variable member may be detachably attached to the outer periphery of the placement unit, and may be exchanged according to the object to be heated. By providing the variable member on the outer periphery of the placement portion, a space for placing the object to be heated can be secured as in the conventional case, and the entire placement portion can be used. By making the variable member replaceable, the direction in which the hot air flows can be arbitrarily changed according to the size and shape of the object to be heated.

  Further, the air direction varying means may be a regulating member that is provided so as to face the opening provided in the heating chamber and regulates that the air blown from the opening directly hits the object to be heated. An opening for blowing air is formed in the heating chamber, and air for cooling the electrical components blows out from the opening, so that the air is not directly applied to the object to be heated by the regulating member.

  In addition, the mounting tray can be stored in a plurality of positions in the vertical direction in the heating chamber, and the outlet is located on the wall surface of the heating chamber from a position higher than the mounting tray stored in the uppermost level to the lowermost level. It can form in the up-down direction over a position lower than the stored mounting tray. By forming the outlet in the vertical direction on the wall surface of the heating chamber, the degree of freedom in selecting the storage position of the mounting tray is also increased. Therefore, the support part which accommodates a mounting tray can be formed in multistage rather than before.

  Regardless of the position in which the mounting tray is stored, the variable member provided on the mounting tray faces the outlet. Therefore, the function of the variable member is sufficiently exhibited, and heating cooking with hot air can be performed evenly on any object to be heated.

  As is clear from the above description, according to the present invention, the hot air blown from the blowout port is not directly blown to the object to be heated by the variable member, regardless of the position of the mounting tray. Preferably, hot air can circulate in the heating chamber. It is possible to suppress scorching and uneven baking of the heated object near the air outlet, and to increase the degree of freedom for placing the placing tray.

  In addition, by preparing several types of mounting trays having different dimensions of the variable member, it is possible to circulate hot air more appropriately according to the shape of the object to be heated, and to further improve the quality of heating.

[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a heating cooker according to the first embodiment of the present invention, FIG. 2 is a side sectional view of the heating cooker of the first embodiment, and FIG. 3 is a table provided with a variable member of the first embodiment. FIG. 4 shows a side sectional view of the mounting plate provided with the variable member of the first embodiment.

  As shown in FIGS. 1 and 2, the heating cooker of the present invention is provided with a box body 11 that is heat-insulated and opened at the front surface, and a heating chamber 12 that is housed in the box body 11 and stores the contents. A heater 13 for heating the stored items, a blower 20 for blowing out hot air heated by the heater 13, and a controller (not shown) for controlling the heater 13 and the blower 20 are provided.

  A heat insulating door 15 is provided on the front surface of the box 11 so as to be openable and closable, and an operation unit 16 for inputting instructions from the user is provided. A control unit including a microcomputer controls the blower 30, the heater 13, and the like based on an instruction input from the operation unit 16.

  The heating chamber 12 has two side walls 31, a back wall 32, a top wall and a bottom wall, and a fan casing 21 of the blower 20 is attached to the back side of the back wall 32. The left and right side walls 31 are formed with a plurality of stages of support portions 19 that support the mounting tray 40.

  The blower 20 includes a centrifugal fan 22 and a motor 23 that drives the centrifugal fan 22. The centrifugal fan 22 is rotatably supported by the fan casing 21 and is disposed to face the back wall 32. The heater 13 is arranged concentrically around the centrifugal fan 22. The rear wall 32 is formed with a suction port 17 for sucking the air in the heating chamber 12 into the fan casing 21 and a blower outlet 18 a for blowing hot air heated by the heater 13 into the heating chamber 12. A suction port 17 is arranged in the center of the back wall 32, and the suction port 17 faces the suction port of the centrifugal fan 22. The suction port 17 is formed to be circular by a plurality of holes.

  Moreover, the blower outlet 18a is distribute | arranged on both right and left sides on both sides of the suction inlet 17. FIG. The blower outlet 18a is formed in a substantially rectangular shape that is vertically long and gathers a plurality of holes each having a diameter of about 5 mm. Thereby, even when the mounting tray 40 is placed at any position from the uppermost end to the lowermost end of the support portions 19 having a plurality of stages, the hot air passes through the surface and the bottom surface of the mounting tray 40.

  In addition, by forming the blower outlet 18a into a punch hole shape that is a collection of a plurality of holes, an effect of preventing leakage of electromagnetic waves to the outside of the heating chamber 12 when using electromagnetic heating together, and further, cleaning of the inside of the heating chamber 12 At the same time, it is possible to obtain the effect of inhibiting cuts on the fingertips by the holes. Moreover, the blower outlet 19a was formed not only in the punch hole shape but also in the vertical direction from a position higher than the mounting tray 40 stored in the uppermost stage to a position lower than the mounting tray 40 stored in the lowermost stage. You may form in one opening shape, a lattice shape, a louver shape, etc.

  As shown in FIGS. 3 and 4, the mounting tray 40 includes a dish-shaped mounting portion 41 having an area equivalent to the horizontal cross section of the heating chamber 12 so that the article S to be heated can be mounted, and a mounting portion. It is comprised by the outer periphery of 41 with the edge part 42 of a flange shape. The mounting tray 40 is placed in the heating chamber 12 by the edge portion 42 being supported by the support portion 19. At this time, gaps are formed between the mounting tray 40 and the back wall 32 and between the mounting tray 40 and the heat insulating door. Thereby, the hot air in the heating chamber 12 can be circulated by passing through the gap.

  A variable member 43 that directs the flow of hot air in an appropriate direction is provided on one side of the edge portion 42. In addition, when the direction in which the mounting tray 40 is put in and out, that is, the front-rear direction is fixed, the variable member 43 is disposed on the edge 42 on either side of the mounting tray 40 in the front-rear direction. The variable member 43 is formed in a pair of left and right. When the mounting tray 40 is placed in the heating chamber 12, the variable member 43 faces the air outlet 18 a formed in the back wall 32.

  The variable member 43 is a trapezoidal flat plate whose upper side is shorter than the lower side. The variable member 43 is formed integrally with the edge portion 42 of the mounting tray 40 and protrudes outward in the vertical direction with respect to the mounting portion 41, that is, obliquely upward as viewed from the side surface of the mounting tray 40. ing. The variable member 43 has a guide surface 46 that guides hot air to the bottom surface side of the mounting tray 40. The guide surface 46 is a surface facing the air outlet 18a, that is, a surface opposite to the placement portion 41 side of the variable member 43. The lateral width of the variable member 43 is larger than the lateral width of the air outlet 18a.

  In addition, the variable member 43 has a height H and an inclination angle θ set according to the object to be heated S placed on the placing plate 40.

  For example, for a heated object S that is relatively low in height, such as a cookie, and that is difficult to receive hot air from the air outlet 18a, a mounting plate 40 provided with a variable member 43 having a low height H is used. Thus, hot air can be applied to the cookie more effectively and it can be heated effectively. Moreover, about the to-be-heated material S with comparatively high height like a butter roll and which the hot air from the blower outlet 18a hits easily, the mounting plate 40 provided with the variable member 41 with high height H is used. Thus, hot air that directly hits the butter roll can be avoided, and scorching and uneven baking can be suppressed. That is, by changing the height H of the variable member 43 in accordance with the height of the object to be heated S, it is possible to effectively apply the hot air to all the objects to be heated S and perform heating effectively.

  The variable member 43 is not limited to a flat plate shape as described in the present embodiment, and may be formed in a curved shape so as to guide the blown hot air to the bottom surface of the mounting tray 40 more appropriately. Further, it may be columnar or tubular.

  Further, the installation angle θ of the variable member 43 is not particularly limited, but it is preferable that θ ≧ 20 degrees in order to guide the hot air efficiently. When θ = 0 degrees, that is, when a part of the air outlet 18a is closed by the variable member 43, the efficiency of the hot air circulation in the heating chamber 12 is slightly impaired, but the hot air is prevented from being blown directly onto the article S to be heated. it can. That is, in view of fulfilling the purpose of solving the conventional problems, a configuration such as θ = 0 degrees may be used as necessary.

  Next, the flow of hot air in the above configuration will be described. First, when a user puts the placing plate 40 on which the article S to be heated is placed into the heating chamber 12 and inputs cooking contents from the operation unit 16, the control unit is based on an instruction input from the operation unit 16. Then, the heater 13, the blower 20, and the like are driven and controlled to start cooking the object S to be heated. At this time, the article to be heated S is blocked by the variable member 43 and does not directly face the outlet 18a.

  The air blown out by the centrifugal fan 22 is heated by the heater 13 to become hot air, and the hot air is blown out from the air outlet 18a. The hot air blown out from the blower outlet 18a hits the variable member 43 provided at a position facing the blower outlet 18a as shown by an arrow in FIG. 2, flows to the bottom surface side of the mounting plate 40, and is blown out by the Coanda effect. It effectively flows to the heat insulating door 15 side without reducing the air volume blown out from 18a. The hot air flows along the bottom surface of the mounting tray 40 toward the front surface through the heating chamber 12, hits the heat insulating door 15, changes the flow direction, and moves toward the center. The hot air blown out from the air outlet 18a above the mounting position of the mounting plate 40 placed on the upper side and the air outlet 18a formed below the mounting plate 40 placed on the lower side, It flows in the heating chamber 12 toward the front surface, hits the heat insulation door 15, changes the flow direction, concentrates in the center, and is sucked from the suction port 17 by the suction force of the blower 30.

  With this variable member 43, desired hot air circulation that uniformly strikes the article to be heated S can be realized, and cooking with less heating unevenness can be performed. That is, since hot air is not directly applied to the tall object to be heated S such as a butter roll or the like, scorching can be prevented. Since hot air flows to the bottom surface side of the mounting tray 40, it can be sufficiently heated from the lower side of the heated object S.

  Moreover, the mounting plate which concerns on this invention can exhibit a desired effect not only when using it for the heating cooker of the said embodiment, but when using for the conventional heating cooker shown in FIG. FIG. 5 is a front view of another type of cooking device according to the first embodiment, and FIG. 6 is a side sectional view of another type of cooking device according to the first embodiment.

  Here, the variable member 43 provided in the mounting tray 40 is formed to have a size that faces the air outlet 18 b at the intermediate position of the back wall 32. In this case, the mounting tray 40 is a mounting tray 40 dedicated to the lower stage. In the case of the mounting tray 40 mounted on the upper stage, the variable member 43 is formed in a size and a position so as to face the air outlet 18b in the upper part of the back wall 32.

  For example, a tall heated object S such as a chiffon cake is placed on the placing tray 40. The mounting tray 40 is mounted on the lower support portion 19. As shown by the arrows in FIG. 6, the hot air blown from the air outlet 18b at the middle position of the back wall 32 hits the variable member 43 provided at a position facing the air outlet 18b, and the bottom side of the mounting plate 40 , Flows along the bottom surface of the mounting tray 40 toward the front surface in the heating chamber 12, hits the heat insulating door 15, changes the flow direction, and moves toward the center. Hot air blown out from the air outlet 18b formed above and below the mounting position of the mounting tray 40 flows through the heating chamber 12 toward the front surface, hits the heat insulating door 15, changes its direction, and concentrates in the center. Then, the air is sucked from the suction port 17 by the suction force of the blower 30.

  By the said structure, it can avoid that the hot air blown off from the blower outlet 18b is directly sprayed on the to-be-heated material S, and can suppress a burning and a burning nonuniformity. In particular, for large cakes such as chiffon cakes, it is preferable to improve the cooking quality by strongly heating from the bottom side. Since the hot air can be guided to the bottom surface side of the mounting tray 40 by the variable member 43, suitable cooking can be performed.

[Second Embodiment]
Next, the case where the mounting dish provided with the wind direction changing means is used in the heating cooker that performs electromagnetic wave heating in addition to the hot air circulation will be described. FIG. 7 is a front view of the cooking device according to the second embodiment, FIG. 8 is a side sectional view of the cooking device according to the second embodiment, and FIG. 9 is a view of the mounting dish provided with the regulating member of the second embodiment. FIG. 10 is a side sectional view of a mounting plate provided with a regulating member according to the second embodiment.

  As shown in FIGS. 7 and 8, the heating cooker includes an electrical component 71 that requires cooling, such as a magnetron for electromagnetic wave heating and a step-up transformer for voltage boosting, and a cooling fan 72 that cools the electrical component 71. ing. The electrical component 71 is disposed adjacent to the side wall 31 of the heating chamber 12. The cooling fan 72 is disposed in the vicinity of the electrical component 71.

  Further, a discharge port 73 is formed in the side wall 31 of the heating chamber 12 as an opening for discharging the cooling air that has cooled the electrical component 71 into the heating chamber 12. A suction port 74 for taking in air for cooling the electrical component 71 from the outside is formed on the rear surface of the outer wall of the box 11. The other structure is the same as the heating cooker shown in FIG.

  External air is sucked from the suction port 74 by the operation of the cooling fan 72, and the sucked air is blown to the electrical component 71 as cooling air. The cooling air that has cooled the electrical component 71 is blown out from the discharge port 73 and the suction port 74. Thereby, the dew condensation in the heating chamber 12 is prevented.

  As shown in FIGS. 9 and 10, the mounting tray 40 has the same structure as that of the first embodiment, but a regulating member 44 that regulates the cooling air blown from the discharge port 73 is provided on one side of the edge portion 42. It has been. In addition, when the direction in which the mounting tray 40 is put in and out, that is, the front-rear direction is determined, the regulating member 44 is disposed on the edge 42 in the left-right direction of the mounting tray 40. The restricting member 44 is basically the same as the variable member 43, but is erected perpendicularly to the edge 42 and has an inclination angle θ of 0 degree. The height H of the restricting member 44 is formed higher than the position of the discharge port 73 formed in the side wall 31, and the width is larger than the width of the outlet.

  When the mounting tray 40 is put into the heating chamber 12, the regulating member 44 faces the discharge port 73. At this time, a slight gap is formed between the regulating member 44 and the side wall 31. The cooling air blown out from the discharge port 73 flows out from the gap between the regulating member 83 and the discharge port 73 to the surroundings. Note that the regulating member 44 may contact the side wall 31 to block the discharge port 73. Further, the mounting plate 40 may be provided with the variable member 43 in addition to the regulating member 44.

  Therefore, the restricting member 44 can suppress the traffic of air through the discharge port 73, and the cooling air blown from the discharge port 73 does not directly hit the article to be heated S. Therefore, it is possible to perform heat cooking with little heating unevenness.

  As described above, the application example of the present invention has been described with reference to the drawings. However, in the present invention, the wind direction changing means of the mounting tray is not limited to this. For example, a windmill or a centrifugal fan may be used, and the variable member may be formed in a warm shape. For example, when the variable member has a warm shape, this becomes a resistance, and the blowing speed of the hot air blown out from the outlet is reduced. When the wind direction changing means is a windmill or a centrifugal fan, hot air hitting the rotating wings is dispersed around. Hot wind is weakened and the flow is changed.

  Moreover, you may form the ventilation path through which a hot air flows in the inside of a mounting tray. An inlet is formed at a position facing the air outlet, and an outlet is formed on the bottom surface of the mounting tray. Hot air entering from the entrance passes through the ventilation path and is discharged from the bottom surface. The entire mounting plate can be heated by the hot air that has passed through the mounting plate.

  Further, the variable member or the regulating member may be detachable. In this case, a holding portion connected to the edge portion is provided at one end portion of the variable member or the regulating member. For example, the end of the variable member is clipped and sandwiched between the edges of the mounting tray, or the end of the variable member and the edge are fitted and held. Further, in the control of the wind direction of the variable member or the regulating member, it may be protruded by inclining inward with respect to the mounting portion as viewed from the side surface of the mounting tray, or may be protruded outward and downward. . The cooked food can be cooked more efficiently without being limited by the place and shape of the cooked food.

  Moreover, you may use the mounting plate provided with the wind direction variable means not only for the heating cooker in which the blower outlet was provided in the back wall but in the heating cooker in which the blower outlet was provided in the side wall and the top wall. In this case, the position of the variable member provided on the mounting tray is different according to the position of the outlet. For example, in the case of a heating cooker in which the air outlet is provided on the side wall, the variable member is provided on the edge in the left-right direction of the mounting tray. In addition, in the case of a heating cooker in which the air outlet is provided on the top wall, a variable member formed in a U-shape or U-shape is provided so as to cover the placement portion when viewed from the front of the placement tray. . Thereby, since the direction in which hot air hits the variable member changes, the hot air does not directly hit the object to be heated. In addition, in the case of such a lid shape, it may be formed so as to be detachable from the mounting plate or to be opened and closed around the hinge.
