  The present invention relates to an oven.

  A convection oven having a single front door is disclosed (see Patent Document 1).

JP-A-11-193925

  The convection oven is a device that sends hot air into a heating chamber and heats cooked foods such as food by radiant heat and convection heat. The convection oven sets and uses the chamber temperature and cooking time. A fan for forcibly circulating hot air is provided in the cabinet. In addition to oven cooking, some convection ovens have a steam cooking function and a simultaneous cooking function of the oven and steam. In addition, some convection ovens improve the baking performance by increasing the cooking speed and uniforming the temperature distribution in the refrigerator by using an internal circulation fan.

  In the heating chamber, a plurality of supporting members for supporting the cooking bat are provided in the upper and lower stages so that a plurality of cooking bats can be accommodated. Therefore, a large amount of cooking can be performed at a time by setting food ingredients in each cooking bat. In addition, cooking is possible simply by setting the cooking mode, temperature and time, which is effective for labor saving. Since cooking is performed in the heating chamber, there is little heat radiation during cooking, and the worker and kitchen environment can be made favorable.

  However, in the above-described conventional example, the food is input and removed by opening and closing one front door. When the front door is opened, the temperature in the heating chamber is greatly reduced. Therefore, it is not opened during cooking, and the cooking is completed by opening the front door after cooking is completed. Accordingly, it is not possible to cope with so-called batch cooking in which different cooking is performed at each stage.

  In consideration of the above facts, an object of the present invention is to be able to cope with cooking of a small variety of products.

  The invention (oven) of claim 1 is provided with a heating chamber in which a plurality of cooking bats can be installed, and provided on the side wall of the heating chamber corresponding to each stage of the cooking bat, and the cooking bats are taken in and out, respectively.

And a door that is opened when passing through the door and is closed in a state where the cooking bat is housed in the heating chamber and a state where the cooking bat is carried out of the heating chamber.

  In this oven, a plurality of cooking bats can be installed in the heating chamber, and each cooking bat can be put in and out separately through an opening provided in each stage. The cooking bat is carried out of the heating chamber through the opening by the drive mechanism. The door provided in the opening is opened when the cooking bat passes through the opening, and is closed in a state where the cooking bat is accommodated in the heating chamber and a state where the cooking bat is carried out of the heating chamber. Therefore, the fall of the heat in the heating chamber at the time of putting in and out the cooking bat can be suppressed. For this reason, it can respond to cooking of a small amount and many kinds.

  The invention according to claim 2 is the oven according to claim 1, wherein the driving mechanism is capable of attaching the cooking bat, and a slide member capable of entering and exiting the inside and outside of the heating chamber through the opening, A drive unit that drives the slide member to at least the outside of the heating chamber; and a control unit that controls the operation of the drive unit.

  In this oven, the slide member is driven to at least the outside of the heating chamber by the drive unit, so that the cooking bat attached to the slide member can be automatically carried out of the heating chamber.

  According to a third aspect of the present invention, in the oven according to the second aspect, the door is at least rotatable to the outside of the heating chamber and biased in a closing direction, and the slide member includes the slide member. There is provided a cam that pushes the door to the outside of the heating chamber when it comes out of the opening and allows the door to close when the cooking bat is unloaded from the heating chamber.

  In this oven, when the slide member exits from the opening, the door of the opening is pushed open to the outside of the heating chamber by a cam provided on the slide member. Since the door is biased in the closing direction, the door is closed when the slide member is carried out of the heating chamber. For this reason, when carrying out the cooking bat, the door can be opened and closed with a simple configuration.

  According to a fourth aspect of the present invention, in the oven according to the third aspect, the door is rotatable to the inside of the heating chamber, and the cam is further moved when the slide member enters the opening. The door is pushed open to the inside of the heating chamber, and the door is allowed to close when the cooking bat is accommodated in the heating chamber.

  In this oven, when the slide member enters the opening, the door of the opening is pushed and opened to the inside of the heating chamber by a cam provided on the slide member. Since the door is biased in the closing direction, the door is closed when the slide member is accommodated inside the heating chamber. For this reason, when accommodating the cooking bat, the door can be opened and closed with a simple configuration.

  According to a fifth aspect of the present invention, in the oven according to any one of the second to fourth aspects, the control unit is provided with a timer for setting a timing for operating the driving unit.

  In this oven, a cooking bat can be carried out by operating the drive unit using a timer, so that cooking is not overheated.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
[First Embodiment]
1 and 2, an oven 10 according to this embodiment is, for example, a steam convection oven, and includes a heating chamber 12, an opening 14, a drive mechanism 16, and a door 18. Since the structure and basic specifications of the oven 10 are the same as known ones, description thereof is omitted. The oven 10 includes ovens other than the steam convection oven.

  In FIG. 1, the heating cabinet 12 is configured so that a plurality of cooking bats 22 can be installed, for example, three stages. The number of stages may be two, or four or more. A front door 24 that is opened when the inside is cleaned is provided in front of the heating chamber 12. Since the cooking bat 22 is put in and out through the opening 14 provided in the side wall 26 of the heating chamber 12, the opportunity to open and close the front door 24 is less than in the prior art. Accordingly, the door handle 28 of the front door 24 is, for example, a flap handle with a small amount of protrusion from the surface of the front door 24.

  A plurality of openings 14 are provided on the side wall 26 of the heating chamber 12 corresponding to each stage of the cooking bat 22 so that the cooking bat 22 can be taken in and out. The opening 14 is formed in a rectangular shape, for example, and has an opening area in which a slide member 30 and the like described later can enter and exit in addition to the cooking bat 22.

  In FIG. 2, the drive mechanism 16 is a mechanism for carrying the cooking bat 22 out of the heating chamber 12 through the opening 14, and includes a slide member 30, a drive unit 32, and a control unit 34. Yes.

  The slide member 30 can be attached with the cooking bat 22 and is configured to be able to enter and exit the inside and outside of the heating chamber 12 through the opening 14. In the present embodiment, the slide member 30 is, for example, a table on which the cooking bat 22 can be placed. The slide member 30 is supported by the rail 40. Note that the slide member 30 is not limited to the structure in which the cooking bat 22 is placed on the slide member 30, and may be configured to directly support the flange portion 22 </ b> F of the cooking bat 22 with the movable portion 44 of the rail 40, for example. .

  Vertical wall portions 30 </ b> A and 30 </ b> B are provided at both ends of the slide member 30 in the slide-in / out direction of the slide member 30 (left-right direction as viewed from the front of the oven 10). The vertical wall portions 30 </ b> A and 30 </ b> B can prevent the cooking bat 22 from dropping when the slide member 30 starts to be driven or stopped. The rail 40 has a fixed part 42 fixed in the heating chamber 12 and a movable part 44 movable in the longitudinal direction of the fixed part 42, and is configured to expand and contract as the slide member 30 moves. Has been.

  On the left side of the vertical wall portion 30B of the slide member 30, a stopper 30C for the door 18 is erected. As shown in FIG. 4, when the cooking bat 22 is carried out of the heating chamber 12, the door 18 comes into contact with the stopper 30 </ b> C. This is to prevent the door 18 from excessively entering the heating chamber 12 due to the urging force and to increase the closing property (air tightness) of the opening 14.

  A cam 50 is provided at the back end of the slide member 30 when viewed from the front of the oven 10. The cam 50 pushes and opens the door 18 to the outside of the heating chamber 12 when the slide member 30 exits the opening 14, and separates from the door 18, for example, when the cooking bat 22 is unloaded from the heating chamber 12. The door 18 is allowed to close. The cam 50 pushes and opens the door 18 to the inside of the heating chamber 12 even when the slide member 30 enters the opening 14, and when the cooking bat 22 is accommodated in the heating chamber 12, for example, from the door 18. At a distance, the door 18 is allowed to close.

  Here, “the cooking bat 22 is carried out of the heating chamber 12” means that a portion of the slide member 30 to which the cooking bat 22 is attached goes out of the heating chamber 12. Therefore, it does not matter whether the cooking bat 22 is actually attached to the slide member 30.

  Similarly, “the cooking bat 22 is accommodated in the heating chamber 12” means that a portion of the slide member 30 to which the cooking bat 22 is attached enters the inside of the heating chamber 12. Therefore, it does not matter whether the cooking bat 22 is actually attached to the slide member 30.

  As shown in FIGS. 1 and 2, the cam 50 is formed in a plate shape in a section from the vertical wall portion 30 </ b> A to the vertical wall portion 30 </ b> B of the slide member 30, for example. Arc portions 50A and 50B are provided, and the arc portions 50A and 50B are connected by a straight portion 50C. The straight portion 50 </ b> C is parallel to the direction in which the slide member 30 enters and exits (the direction in which the rail 40 extends and contracts) and is the highest portion of the cam 50. The height position of the straight portion 50C is set to be sufficiently higher than the cooking bat 22 attached to the slide member 30 and lower than the upper end of the door 18 described later. This is to suppress interference between the food on the cooking bat 22 and the door 18 due to the opening degree of the door 18 being reduced, and to allow the cam 50 to pass through the opening 14 together with the slide member 30. . The shape of the cam 50 is not limited to the above, and can be changed as appropriate.

  The drive unit 32 is an actuator for driving the slide member 30 to at least the outside of the heating chamber 12. As the drive part 32, the structure which drives a belt conveyor and a rack and pinion mechanism with a motor can be considered, for example. The drive unit 32 may have not only a function of driving the slide member 30 to the outside of the heating chamber 12 but also a function of driving the slide member 30 to the inside of the heating chamber 12.

  The control unit 34 is a computer, a driver, or the like for controlling the operation of the drive unit 32. The controller 34 is provided with a timer 46 for setting the timing for operating the drive unit 32. In FIG. 1, an operation unit 48 corresponding to each stage is provided on the left front surface of the heating chamber 12, and the operation of the timer 46 is performed by the operation unit 48. The operation unit 48 includes a display unit 52, operation buttons 54, and the like, and can perform various operations such as temperature setting in addition to the operation of the timer 46.

  Further, as shown in FIG. 2, the control unit 34 is provided with a buzzer 36 that rings when the drive unit 32 is operated. The drive unit 32 operates when the time set by the timer 46 has elapsed. Therefore, the sounding timing of the buzzer 36 may be when the time set by the timer 46 has elapsed. The ringing of the buzzer 36 can inform the surroundings that the cooking bat 22 has been carried out of the heating chamber, that is, that cooking has been completed.

  1 and 2, the door 18 is provided in the opening 14 so as to be openable and closable, opened when the cooking bat 22 passes through the opening 14, and the cooking bat 22 is accommodated in the heating chamber 12.

It is biased in the closing direction by a spring or the like (not shown). When the hinge 56 of the door 18 is provided on the upper side of the door 18 as in this embodiment, the door 18 does not necessarily have to be biased in the closing direction. This is because the door 18 naturally closes due to its own weight. When the hinge 56 is provided on the lower side of the door 18, it is necessary to bias the door 18 in the direction in which the door 18 is closed.

(Function)
This embodiment is configured as described above, and the operation thereof will be described below. In FIG. 1, in the oven 10 according to the present embodiment, a plurality of cooking bats 22 can be installed in the heating chamber 12, and the cooking bats 22 are put in and out separately through the openings 14 provided in the respective stages. It can be carried out.

  The cooking bat 22 is attached to the slide member 30 in the driving mechanism 16 and is carried out of the heating chamber 12 through the opening 14 by the driving mechanism 16. Specifically, when the time set by the timer 46 has elapsed, the control unit 34 operates the drive unit 32 to carry out the cooking bat 22 and cause the buzzer 36 to ring. The slide member 30 is driven to at least the outside of the heating chamber 12 by the drive unit 32. At this time, the movable portion 44 of the rail 40 extends to the outside of the heating chamber 12 together with the slide member 30 to support the slide member 30. Thereby, the cooking bat 22 attached to the slide member 30 can be automatically carried out of the heating chamber 12. At this time, by using the timer 46, the cooking bat 22 can be carried out to the outside of the heating chamber 12 at a timing suitable for each dish. Further, the buzzer 36 can notify the surroundings that the cooking bat 22 has been carried out of the heating chamber, that is, that cooking has been completed.

  Here, the effect | action of the door 18 of the opening part 14 at the time of carrying out the cooking bat 22 to the outer side of the heating chamber 12 is demonstrated. The door 18 is opened when the cooking bat 22 passes through the opening 14 (FIG. 3), and is closed in a state where the cooking bat 22 is accommodated in the heating chamber 12 and carried out of the heating chamber 12. (FIG. 2). Specifically, as shown in FIG. 3, when the slide member 30 exits from the opening 14, the door 18 of the opening 14 is moved outside the heating chamber 12 by a cam 50 provided on the slide member 30. Is pushed open. The door 18 gradually opens while contacting along the arc portion 50A of the cam 50, and reaches the maximum opening at the straight portion 50C. For this reason, the door 18 can be opened gently.

  Since the straight portion 50C is parallel to the direction in which the slide member 30 enters and exits (the direction in which the rail 40 extends and contracts) and is the highest portion of the cam 50, the door 18 remains in contact with the straight portion 50C. Is the maximum opening. Therefore, interference between a dish (not shown) on the cooking bat 22 and the door 18 can be suppressed.

  Since the door 18 is biased in the closing direction, as shown in FIG. 4, when the cooking bat 22 is carried out of the heating chamber 12, the door 18 is separated from the cam 50 and is closed. While the door 18 is in contact with the arc portion 50B of the cam 50, the door 18 gradually closes along the arc portion 50B. For this reason, the way of closing the door 18 can be made gentle. Further, when the door 18 is separated from the cam 50, the door 18 is in contact with the stopper 30C of the slide member 30 and is closed. Accordingly, the door 18 is prevented from entering the heating chamber 12 excessively, and the closing property (airtightness) of the opening 14 in the state where the cooking bat 22 is carried out is increased, and the temperature of the heating chamber 12 is decreased. Can be suppressed.

  Since the cam 50 is provided at the back end of the slide member 30 when viewed from the front of the oven 10, it does not hinder the attachment and removal of the cooking bat 22 from the slide member 30.

  Next, an operation when the slide member 30 is accommodated in the heating chamber 12 will be described. As an example, a cooking bat 22 on which food (not shown) is placed is attached to the slide member 30. As shown in FIG. 5, the slide member 30 to which the cooking bat 22 is attached is housed in the heating chamber 12 manually or by driving of the drive unit 32. When the slide member 30 enters the opening 14, the door 18 of the opening 14 is pushed open to the inside of the heating chamber 12 by the cam 50 provided on the slide member 30. The door 18 gradually opens while contacting along the arc portion 50B of the cam 50, and reaches the maximum opening at the straight portion 50C. For this reason, the door 18 can be opened gently.

  Since the straight portion 50C is parallel to the direction in which the slide member 30 enters and exits (the direction in which the rail 40 extends and contracts) and is the highest portion of the cam 50, the door 18 remains in contact with the straight portion 50C. Is the maximum opening. Therefore, interference between the food (not shown) on the cooking bat 22 and the door 18 can be suppressed.

  As shown in FIG. 2, since the door 18 is biased in the closing direction, the door 18 is closed when the slide member 30 is accommodated inside the heating chamber 12. Even when the cooking bat 22 is not attached to the slide member 30, the action when the slide member 30 is accommodated in the heating chamber 12 is the same as described above.

  Thus, in this embodiment, by using the cam 50, the door 18 can be opened and closed with a simple configuration when the cooking bat 22 is taken in and out of the heating cabinet 12. Thereby, the fall of the heat in the heating chamber 12 at the time of putting in and out the cooking bat 22 from the heating chamber 12 can be suppressed. In addition, since the cooking bat 22 can be taken in and out separately through the openings 14 provided in each stage, it is possible to cope with a small amount of various types of cooking. Therefore, in a restaurant chain store or the like, it is possible to freely cook dishes whose heating time is manualized. That is, it can respond to batch cooking.

  In addition, a lamp that is turned on during cooking and turned off when cooking is completed may be provided corresponding to each stage of the heating chamber 12.
