Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baking oven apparatus, and more particularly, to a baking oven apparatus for business use that does not require a large space for loading and unloading bread dough on the front side of the oven.

[0002]

2. Description of the Related Art Baking ovens for business use are large in size, and a large dedicated space for loading / unloading work is secured in front of the oven in order to load / unload a large tray containing bread dough into / from a desired oven shelf. Need to be kept. This dedicated space for work is necessary when loading and unloading the bread dough, but it is a wasteful space after the loading and unloading of the dough, which is a problem for effective use of the space.

Therefore, the inventor of the present invention can freely move up and down by an elevating mechanism and can carry the bread dough into an oven shelf at a desired height position in order to eliminate the above-mentioned exclusive space, and After completion of loading, a baking oven device was proposed, which is equipped with a bread dough loading mechanism that is stored in the upper ceiling position of the oven device so that it does not project outside (France Patent Publication No. 27104).
No. 97). According to this oven device, the bread dough carry-in mechanism can be pulled out and used only when necessary, so that the exclusive space on the front surface of the oven device is not required and the space can be effectively used.

[0004]

However, in the case of the above-mentioned oven apparatus for baking bread, the bread dough carry-in mechanism is designed to be stored in the storage compartment formed in the upper ceiling of the oven and communicating with the inside of the oven. , I found the following problems when actually used.

That is, since the hangar itself that stores the bread dough carry-in mechanism is also exposed to the atmosphere of the oven in which the temperature changes drastically, dew condensation occurs on the ceiling surface of the hangar and the dew drops fall onto the bread dough carry-in mechanism. Sometimes. Therefore, there is a problem that the bread dough carry-in mechanism is damaged and the life of the bread dough carry-in mechanism is shortened.

The present invention has been made in order to solve the above problems, and does not require a dedicated space in front of the oven and prevents the formation of dew condensation to prevent the bread dough carry-in mechanism from being damaged. It is an object of the present invention to provide a baking oven device.

[0007]

In order to achieve the above object, a baking oven apparatus of the present invention includes an elevating mechanism which is located on the front surface of an oven shelf and is vertically movable. In a bread baking oven apparatus having a bread dough carry-in mechanism that is placed and can be moved back and forth in the front and rear direction of the oven shelf, the ceiling part upper surface position of a heat insulating outer wall surrounding the periphery of the oven shelf is set to the bread dough carry-in mechanism. As a carrying-in mechanism for storing, a storage space is provided to open the upper space of the storage room to the outside air, and an exhaust housing for discharging the hot air discharged from the oven shelf to the outside is provided on the front side ceiling portion of the storage case, An opening / closing damper that is opened and closed by being pushed by the bread dough carry-in mechanism when the bread dough carry-in mechanism comes in and out is provided at an opening of an entrance of the hangar. A.

[0008]

In the bread baking oven apparatus of the present invention, the ceiling upper surface of the heat insulating outer wall that covers the upper surface of the uppermost oven shelf serves as a carry-in mechanism storage for storing the bread dough loading mechanism, and the upper space of this storage is exposed to the atmosphere. Since the opening of the hangar that serves as the entrance and exit of the bread dough carry-in mechanism is closed with the opening / closing damper, the hot air from the oven will not enter the hangar. Further, even if hot air enters, the hangar is open to the atmosphere, so that it is quickly radiated to the outside. Therefore, the temperature in the hangar does not rise so much and the temperature change is extremely small, so that dew condensation does not occur in the hangar. Therefore, it is possible to prevent dew condensation on the bread dough carry-in mechanism and damage the bread dough carry-in mechanism. Further, since the hot air from the front side inlet / outlet portion of the oven is directly discharged upward from the exhaust housing, the hot dough does not hit the bread dough carry-in mechanism. Furthermore, since the bread dough carry-in mechanism can be used by pulling it out from the carry-in mechanism storage only when necessary, a dedicated space in front of the oven can be eliminated.

[0009]

The vertical iron plate 22 is configured to move up and down in parallel.

Further, two lower rollers 25 and 26 and one upper roller 2 are provided on the inner surface of the carry-in mechanism guide plate 23.
7 are provided. The distance between the lower roller 26 and the upper roller 27 is the frame plate 11 of the bread dough loading mechanism 9 (see FIG. 3).
It is set to be slightly larger than the plate height of the bread dough loading mechanism 9, and the left and right frames 11 and 11 of the bread dough loading mechanism 9 are set on the lower rollers 2 of the left and right loading mechanism guide plates 23, as shown by the two-dot chain line in FIG.
The bread dough carry-in mechanism 9 is configured to be movable in the front-rear direction on the carry-in mechanism guide plate 23 by being placed on 5, 26 and inserted into the upper roller 27.

Further, at the upper edge of the carry-in mechanism guide plate 23, there is formed a lock recess 28 having a size into which the end of the lock bar 15 of the bread dough carry-in mechanism 9 is fitted. The left and right ends of 15 are fitted into the locking recesses 28 of the left and right loading mechanism guide plates 23, thereby locking the loading belt 14 at the positions.

A chain 29 is connected to the vertical iron plate 22 of the lifting mechanism 10, and the other end of the chain is pulled out to the back side of the heat insulating outer wall 7 by pulleys 30 and 31, and a weight 32 is hung at the tip thereof. It has been lowered. This weight 3
2 is adjusted to have a weight that substantially balances the total weight of the bread dough carry-in mechanism 9 and the elevating mechanism 10. When the bread dough carry-in mechanism 9 is pulled out, the bread dough carry-in mechanism 9 is adjusted.
It is devised so that the bread dough carry-in mechanism 9 and the lifting mechanism 10 can be smoothly moved up and down by a slight force when the handle bar 13 is pushed down or pushed up.

The oven shelf 1, the heat insulating outer wall 7, the bread dough carry-in mechanism 9 and the elevating mechanism 10 are entirely housed in the apparatus casing 40. A box-shaped exhaust housing 42 is provided at the upper ceiling position of the vertical rail 8 on the front side of the apparatus housing 40, and the heat exhausted from the oven shelf 1 is efficiently externalized by the exhaust housing 42. Is configured to be discharged to.

Further, between the lower end portion of the wall surface of the exhaust housing 4 and the upper surface 43 of the ceiling portion of the heat insulating outer wall 7, there is formed an opening portion 44 having an opening for inserting and removing the bread dough loading mechanism 9. A carry-in mechanism storage box 45 is formed for pushing the bread dough carry-in mechanism 9 and storing it when the carry-in mechanism 9 is not used.

An opening / closing damper 46 made of a flexible rubber or a hinged metal plate is attached to the opening / closing opening 44 of the bread dough carry-in mechanism 9, and each oven shelf 1 The exhaust heat is closed so as not to enter the carry-in mechanism housing 45, and the ceiling upper space of the heat insulating outer wall 7 forming the carry-in mechanism housing 45 is an open space communicating with the outside air. .

The present invention, as described above, has the carrying-in mechanism housing 4
The opening 44 serving as the entrance and exit of 5 is covered with the opening / closing damper 44, and the carry-in mechanism storage 45 is further opened to the outside air so that exhaust heat during baking is prevented from entering the carry-in mechanism storage 45. Even if exhaust heat enters, the heat is quickly radiated from the open space to the atmosphere to prevent dew condensation in the carry-in mechanism storage box 45.

In the case of the baking oven of the illustrated example, as shown in FIG. 1, a switch for setting and adjusting the baking temperature and the baking time for each oven shelf is provided at the left end position on the front surface of the apparatus. An operation unit 47 including buttons and buttons is provided. Further, the knob 48 adjacent to the operation portion 47 is a smoke exhaust damper operation knob for opening and closing the smoke exhaust port provided in each oven shelf (not shown).

Next, with reference to FIGS. 1 to 12, the operation and handling method of the bread baking oven device having the above-mentioned configuration will be described.

When not in use, the bread dough carry-in mechanism 9 of the bread baking oven is stored in the carry-in mechanism storage box 45 as shown in FIG. Therefore, no bulge or exclusive space is required on the front surface of the device, so that the space on the front surface of the device can be effectively utilized.

Next, when baking bread, first grasp the handle bar 25 of the bread dough carry-in mechanism 9 in the state shown in FIG.
The entire dough feeding mechanism 9 is pulled toward you. As a result, the bread dough carry-in mechanism 9 is guided by the three rollers 25 to 27 of the carry-in mechanism guide plate 23 of the elevating mechanism 10 while rolling with the rollers 18 provided on the lower surface of the tip thereof, and is pulled out to the state of FIG. .

Assuming now that the bread dough is to be carried into the oven shelf 1 at the lowermost stage, the bread dough carry-in mechanism is pushed down slightly while holding the handle bar 25 of the bread dough carry-in mechanism 9 in the state shown in FIG. Since 9 and the lifting mechanism 10 are weight-balanced with the weight 32 suspended on the other end of the chain 29, the vertical rail 8 is guided by the two rollers 21 of the vertical iron plate 22 of the lifting mechanism 10. Along the bottom, it descends toward the oven shelf 1 at the bottom. When the pressing of the handle bar 25 is stopped when the bread dough carry-in mechanism 9 descends to a position facing the lowest oven shelf 1,
The bread dough carry-in mechanism 9 stops at a position facing the lowest oven shelf 1 shown in FIGS. 6 and 7.

Next, in the state shown in FIGS. 6 and 7, the rotary knob 16 attached to the upper surface of the carry-in belt 14 is grasped and lifted, and both ends of the locking bar 15 are engaged with the carry-in mechanism guide plate 23. After removing from the stop recess 28, the rotary knob 16 is held and pulled toward the front side, and the carry-in belt 14 is rotated toward the front side until the locking bar 15 reaches the positions shown in FIGS. 8 and 9. . Then, when the locking bar 15 reaches the position shown in FIGS. 8 and 9, the rotary knob 1
6 is released, and the bread dough 51 processed into a desired shape is placed on the carry-in belt 14 and arranged.

Bread dough 5 in the state shown in FIGS. 8 and 9.
After loading 1, the opening door 3 made of heat-resistant glass attached to the front of the oven shelf 1 is opened, and the bread dough carry-in mechanism 9 is pushed into the oven shelf 1 until the state shown in FIG. When the bread dough carry-in mechanism 9 is pushed into the state shown in FIG. 10, both ends of the locking bar 15 are lifted and lowered by the lifting mechanism 10.
Of the loading mechanism guide plate 23,
It is locked in this position.

After the bread dough carry-in mechanism 9 is pushed to the state shown in FIG. 10, the handle bar 17 is again held and the bread dough carry-in mechanism 9 is pulled toward the front side and pulled out from the oven shelf 1, and both ends of the locking bar 15 are pulled. Part is the loading mechanism guide plate 23
Since it is fitted and locked in the locking recess 28 of
The carry-in belt 14 turns in the counterclockwise direction (in FIG. 10) as the frames 11, 11 move to the front side,
As shown in FIG. 11, the bread dough 51 placed on the carry-in belt 14 is sent out from the carry-in belt 14 onto the oven shelf 1.

When the bread dough carry-in mechanism 9 is completely pulled out to the state shown in FIG. 12, the bread dough 12 is moved to and placed on the oven shelf 1 as shown in FIG. As a result, the loading of the dough into the oven shelf 1 at the bottom by the dough loading mechanism 9 is completed. Subsequently, when it is desired to carry the bread dough into another oven rack, the bread dough carry-in mechanism 9 may be moved up and down to the target oven rack position, and the same operation as described above may be performed.

When the bread dough has been carried into all the oven shelves or the desired oven shelves, the bread dough carry-in mechanism 9 is pushed up toward the opening 44 of the carry-in mechanism storage box 45 at the uppermost stage, and the position shown in FIG. Move to position. In the state of FIG. 5, when the bread dough carry-in mechanism 9 is pushed toward the opening 44, the bread dough carry-in mechanism 9
The opening / closing damper 46 is pushed open at the tip of the tray, and the bread dough carry-in mechanism 9 is stored in the carry-in mechanism storage box 45 as shown in FIG.

After storing the bread dough carry-in mechanism 9 in the carry-in mechanism storage box 45 as described above, the opening / closing door 2 made of heat-resistant glass on the front of each oven shelf 1 is closed, and the switches and buttons of the operation section 47 are operated. After setting the baking temperature and baking time, the heaters 4 and 5 are turned on to start baking.

When baking is started, each oven shelf 1
Although the internal temperature rises, the carry-in mechanism housing 45 formed at the uppermost position of the apparatus is thermally separated by the heat insulating outer wall 7, so that the heat in the oven is hardly transferred. Even if it is transmitted, since the upper portion of the carry-in mechanism housing 45 is opened to the atmosphere, heat is quickly dissipated, and the temperature in the carry-in mechanism housing 45 does not rise to a high temperature.

Further, the hot air in each oven shelf 1 leaks through the gap of the opening / closing door 45 on the front and rises upward on the front side of the oven. Since the exhaust housing 42 is provided, the leaked hot air is quickly discharged to the outside through the exhaust housing 42.

Further, the opening 44 of the carry-in mechanism housing 45
Since an opening / closing damper 46 made of a flexible rubber or a metal plate joined by a hinge is attached to the opening, the opening 44 is closed by the opening / closing damper 46, and hot air is stored in the loading mechanism housing 45. Are prevented from entering. Even if hot air enters the carry-in mechanism hangar 45 through a gap between the opening / closing dampers 46, the upper part of the carry-in mechanism hangar 45 is exposed to the atmosphere and is quickly radiated, so that the temperature inside the carry-in mechanism hangar 45 is reduced. Does not reach high temperatures.

Therefore, in the case of the baking oven device having the above-mentioned structure, the temperature in the carry-in mechanism storage box 45 does not rise so much and the temperature change does not increase so much during baking of bread. For this reason, dew condensation does not occur in the carry-in mechanism storage box 45, and it does not occur that the dew drops on the stored bread dough carry-in mechanism 9 and damages the carry-in belt 14 and the like.

By the way, the baking oven apparatus of French Patent No. 2710497 proposed by the present inventor has a structure as shown in FIG. 13, and is different from the baking oven apparatus according to the above-mentioned embodiment. Thus, the structure of the carry-in mechanism storage 52 is different. That is, in the case of the baking apparatus of this prior application, the carry-in mechanism storage 52 for storing the bread dough carry-in mechanism 9 is a closed space, and the inlet / outlet part of the bread dough carry-in mechanism 9 is also an open port. This is because the heat generated from each oven shelf 1 has entered the carry-in mechanism storage 52 and has caused dew condensation on the storage ceiling.

[0040]

As described above, according to the present invention,
The ceiling upper surface position of the heat insulating outer wall surrounding the periphery of the oven shelf serves as a carry-in mechanism hangar for storing the bread dough carry-in mechanism, the upper space of the hangar is opened to the outside air, and the front side ceiling part of the hangar is An exhaust housing is provided to discharge the hot air discharged from the oven shelf to the outside, and an opening and closing damper that is opened and closed by the bread dough loading mechanism when the bread dough loading mechanism enters and leaves the oven is installed at the opening of the hangar. The hot air does not enter the hangar, and even if the hot air enters, the hangar is open to the atmosphere, so that heat can be quickly radiated to the outside. For this reason, the temperature in the hangar does not rise so much and the temperature change is extremely small, so that dew condensation does not occur in the hangar. Therefore, it is possible to prevent dew condensation on the bread dough carry-in mechanism stored in the hangar and damage the bread dough carry-in mechanism.

Further, according to the present invention, since the bread dough carry-in mechanism can be used by pulling it out from the carry-in mechanism housing only when necessary, it is possible to eliminate the need for an exclusive space in front of the oven, and to effectively use the space. Can be planned.
