DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control cabinet for baking, which is used for providing freshly baked bread in hotels, shops, etc., and more particularly, to dew condensation of a humidity sensor provided in the cabinet. Prevention technology.

[0002]

2. Description of the Related Art As one of devices for efficiently providing freshly baked bread in stores and the like, there is a bread-making temperature and humidity control cabinet called a deconditioner. In this method, frozen bread dough is thawed in a refrigerator for a predetermined period of time, and then ripening for improving the fermentation state and proofing for actual fermentation are sequentially performed. According to this, for example, a series of processes such as thawing, aging, and proofing of bread dough can be automatically performed in advance at night when there is no worker, so that the worker can immediately start baking bread from the early morning. It becomes possible.

[0003] Fig. 5 shows an example of a conventional bread making temperature and humidity control cabinet. In FIG.
Is provided with a partition panel 6 on one side of the compartment C, and the compartment panel 6 divides the compartment C into a storage chamber 2 in which bread dough is stored.
And a machine room 7 in which a temperature control means (heat exchanger or the like) 12 and an air circulation means (fan or the like) 13 are provided. Above and below the partition panel 6, an upper communication portion (air outlet) 1 for communicating the storage room 2 and the machine room 7 with each other.
0 and a lower communication portion (air suction port) 11 are formed.

[0004] In such a bread-making temperature and humidity control cabinet 1, the air whose temperature has been adjusted in the machine room 7 is blown out from the upper communication part 10 to the storage room 2 by the air circulation means 13 in the machine room 7. After that, it flows downward through the gap around the panel 39 provided on the ceiling of the accommodation room 2,
Passing between the dough (not shown) set in the
It is sucked into the cabin 7 from the lower communication part 11 below the partition panel 6. Thereafter, the air is blown out again from the upper portion on the machine room 7 side to the accommodation room 2 side via the upper communication portion 10. Thus, the temperature and humidity of the inside C are made uniform by forming the air flow S circulating in the inside C by the air circulation means 13.

[0005] Here, although omitted in FIG. 5, a humidity adjusting means for adjusting the humidity of the inside C is provided in a machinery storage space provided at an upper portion of the baking temperature and humidity control cabinet 1 or the like. Is provided with a humidifier (usually an ultrasonic humidifier) for supplying humidified air to the inside C of the refrigerator. Then, by supplying humidified air from the humidifier to the interior C as needed through a duct (not shown) having one end opened into the interior, the humidity of the interior C is adjusted. I have.

[0006] Generally, in a temperature and humidity control cabinet for bread making, it is important to maintain not only the temperature in the cabinet but also the humidity in an appropriate state in order to perform thawing and fermentation without deteriorating the quality of the dough. It is. For this reason, in the conventional bread making temperature and humidity control cabinet 1, as shown in FIG.
A humidity sensor 23 for detecting the humidity in the refrigerator is attached to the lower portion of the surface on the machine room 7 side, that is, in the vicinity of the lower communication portion 11, and based on the output of the humidity sensor 23, a humidifier (not shown) is connected via a humidification duct. By appropriately supplying humidified air to the interior C, the interior C is maintained at a predetermined humidity (set value).

[0007]

However, in this kind of temperature and humidity control room for bread making, the temperature in the room is reduced from a relatively low temperature such as when shifting from a frozen storage process to a fermentation process. Immediately after a relatively rapid change to a high temperature, the humidity sensor may condense. Such a phenomenon, for example,
This is caused by the moisture contained in the air inside the refrigerator coming into contact with the surface of the humidity sensor that has not yet reached the same temperature as the ambient temperature. Detection becomes difficult.

In particular, in the case of the bread-making temperature and humidity control cabinet 1 as shown in FIG. 5 in which a humidity sensor is attached to the surface of the partition panel on the machine room side, the lower communication portion 11 located below the partition panel 6. It is difficult for the airflow S sucked into the machine room 7 to directly hit the humidity sensor 23, so that dew condensation easily occurs. For this reason, the detection of the humidity in the refrigerator is delayed, and the air in the refrigerator C may be excessively humidified (so-called humidification overshoot), or the amount of humidification may be insufficient. There was a problem that it was not possible.
In addition, when the humidity sensor 23 is attached to the surface of the partition panel 6 on the machine room 7 side as described above, the humidity sensor 2
Since the partition panel 6 must be removed when replacing the humidity sensor 3, the operation of replacing the humidity sensor 23 is extremely troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a temperature and humidity control cabinet for bread making, in which dew condensation of a humidity sensor hardly occurs and the replacement operation thereof can be easily performed.

[0010]

SUMMARY OF THE INVENTION The present invention provides a temperature control means (specifically, a heat exchanger and a heater) for controlling the temperature in a refrigerator, and a humidity control means (specifically, a heat exchanger and a heater) for controlling the humidity in the refrigerator. For example, the present invention is applied to a bread making temperature / humidity control cabinet including an ultrasonic humidifier) and air circulation means (specifically, a fan or the like) for circulating air in the cabinet. As shown in FIG. 1, in this bread making temperature and humidity control cabinet, a partition panel 6 is arranged on one side of the cabinet C, and the compartment panel 6 allows the cabinet C to store bread dough. It is divided into a room 2 and a machine room 7. Above and below the partition panel 6, an upper communication portion 10 that connects the accommodation room 2 and the machine room 7 to each other.
And a lower communication portion 11. In the machine room 7, the temperature control means 12 and the air circulation means 13 are arranged. Then, the temperature and humidity in the storage chamber 2 are made uniform by the air flow S circulating in the storage C. In FIG. 1, reference numeral 8 denotes a tray for placing dough.

[0011] In such a bread-making temperature and humidity control cabinet 1, the present invention is characterized in that it is configured as follows.
That is, as shown in FIG. 1, a ceiling duct 20 is formed on the ceiling portion of the storage room 2 on the side of the accommodation room 2, and
Is communicated with the machine room 7 via the upper communication part 10. At the other end of the ceiling duct 20, the air inside the machine room 7 passes through the ceiling duct 20 and enters the storage room 2 from near the upper part of the one side wall surface 21 of the compartment C located on the opposite side to the machine room 7. An air outlet 20a is provided so as to be blown out. Also, on the one side wall surface 21, a part of the air blown out from the air outlet 20 a to the upper part in the accommodation room 2 is guided downward along the one side wall surface 21 in the accommodation room 2. A circulation duct 22 having an air inlet 22a at an upper end and an air outlet 22b at a lower end is provided. And this circulation duct 2
A humidity sensor 23 for detecting humidity in the refrigerator is disposed at a position where air blown from the second air outlet 22b hits.

More specifically, the ceiling duct 20 has a closed cross-sectional structure including the upper wall surface 18 of the interior C and a duct panel 19 disposed below the upper wall surface 18. This ceiling duct 20
Is set to be smaller by a predetermined amount than the distance between the one side wall surface 21 of the compartment C located on the opposite side to the machine room 7 and the partition panel 6, so that the ceiling duct 20 and the side A predetermined gap G is formed between the ceiling duct 20 and the wall surface 21, and the end face of the ceiling duct 20 on the gap G side is opened as an air outlet 20a.

The circulation duct 22 is set at a depth in the range of 1/3 to 2/3 of the depth in the refrigerator, and is disposed at an intermediate position in the depth direction of the refrigerator C. The air inlet 22a of the circulation duct 22 faces the gap G, and the air outlet 22b of the circulation duct 22 is disposed at a substantially intermediate position in the height direction of the inside C of the refrigerator. A humidity sensor 23 is detachably attached to the one side wall 21 so as to be located immediately below the air outlet 22b of the circulation duct 22.
In that case, the humidity sensor 23 can be detachably attached to the one side wall 21 using an attachment member such as a fastener.

[0014]

In the bread-making temperature and humidity control cabinet 1 of the present invention, first, the air whose temperature is controlled by the temperature control means 12 in the machine room 7 is
It is sent into the ceiling duct 20 via the upper communication part 10 located above the partition panel 6 by the air circulation means 13,
Air is blown into the storage chamber 2 from the air outlet 20a located on the opposite side of the machine room 7. The blown air flows toward the partition panel 6 through the storage chamber 2 in which the dough is stored, and is then sucked into the machine room 7 from the lower communication portion 11 formed at the lower portion of the partition panel 6. Thus, the temperature of the inside C is made uniform by the formation of the airflow S circulating in the inside C. On the other hand, air containing fine mist, that is, humidified air, is supplied from the humidity control unit to the inside C as needed (see FIG. 3). This humidified air is airflow S
Circulates inside the refrigerator C while diffusing on the. Thereby, the humidity in the refrigerator C is adjusted to be uniform and the predetermined humidity at the same time.

In the above case, a part of the air blown into the storage chamber 2 from the air outlet 20a of the ceiling duct 20 is supplied to one side wall surface 21 of the inside C located on the opposite side to the machine room 7.
Into the circulation duct 22 provided at the lower end, and is blown downward from the air outlet 22b at the lower end through the inside. In that case, in the bread making temperature and humidity control cabinet 1 of the present invention, the humidity sensor 23 is disposed at a position where air blown from the air outlet 22b of the circulation duct 22 hits, specifically, directly below the air outlet 22b. As a result, the air blown out from the air outlet 22b always hits the humidity sensor 23, so that the humidity sensor 23 is less likely to condense. Also,
Even if the humidity sensor 23 forms dew, since the air blown out from the air outlet 22b of the circulation duct 22 always hits the humidity sensor 23, the condensed portion dries relatively quickly. Thus, dew condensation of the humidity sensor 23 can be prevented or suppressed, and as a result, the humidity in the refrigerator can be accurately detected.

Since the air blown out from the air outlet 22b of the circulation duct 22 always directly hits the humidity sensor 23, even when the humidity in the refrigerator changes, such as during humidification, the humidity in the refrigerator that changes every moment is quickly detected. You. Therefore, humidification overshoot caused by delay in detection of the humidity in the refrigerator during humidification is reduced, and more accurate humidity control becomes possible.

If the humidity sensor 23 is detachably attached to the position just below the air outlet 22b of the circulation duct 22 on one side wall surface 21 located on the side opposite to the machine room 7, the partition panel will be different from the conventional one. It is possible to easily remove or attach only the humidity sensor 23 without removing each one. Therefore, the replacement work of the humidity sensor 23 becomes easy.

When a predetermined gap G is formed between the one side wall surface 21 and the ceiling duct 20, and the air inlet 22 a of the circulation duct 22 faces this gap G, the air blowing Part of the air blown out from the outlet 20a flows into the storage chamber 2 from the upper side of the inside C, and the rest flows into the circulation duct 22. In that case, the depth dimension of the circulation duct 22 is set in the range of 1/3 to 2/3 of the depth dimension of the interior C, and the circulation duct 22 is arranged at an intermediate position in the depth direction of the interior C. In this case, substantially all of the air flowing out of the air outlet 20a of the ceiling duct 20 flows into the storage chamber 2 from the upper side of the storage C on the front side and the rear side of the storage C. At the center in the depth direction, a part of the air that has flowed out from the air outlet 20a of the ceiling duct 20 flows into the storage chamber 2 from the upper side of the interior C, and the rest passes through the circulation duct 22 to reach the lower end. The air is blown into the accommodation chamber 2 from the air outlet 22b. At this time, the air outlet 22b of the circulation duct 22
Is arranged at a substantially middle position in the height direction of the interior C,
The air that has passed through the circulation duct 22 is blown downward from the storage chamber 2 from a substantially intermediate position in the height direction in the refrigerator. In this way, air flows uniformly into the storage chamber 2 from both the upper side of the chamber C and the substantially middle position in the height direction, and the temperature and humidity of the chamber C are efficiently uniformed by the airflow S formed by these. Will be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 2 to 4 show an example of a bread-making temperature and humidity control cabinet to which the present invention is applied. 2 and 3, the bread making temperature and humidity control cabinet 1 has upper and lower two accommodation rooms 2 for accommodating bread dough.
A door 3 for opening and closing the opening on the front side is provided. Above the bread making temperature and humidity control cabinet 1, there is provided a mechanical storage unit 4 for storing an ultrasonic humidifier 16 (see FIG. 3) described later. In addition, on the front side of one side of the bread making temperature and humidity control cabinet 1, various information such as humidity in the cabinet is displayed,
Further, an operation panel 5 for inputting predetermined setting values and the like is arranged.

As shown in FIG. 3, a partition panel 6 is provided on one side (right side in the example in the figure) of the inside C of the bread making temperature and humidity control cabinet 1. The interior C is partitioned into the accommodation room 2 described above and a machine room 7 which forms a part of a passage of the air circulating in the interior C.
Here, each accommodation room 2 is provided with a plurality of tray receivers 9 on both left and right sides of the accommodation room 2 for receiving a tray 8 for placing dough. Above and below the partition panel 6, an upper communication portion 10 and a lower communication portion 11 for connecting the accommodation room 2 and the machine room 7 respectively are provided. Among these, the lower communication part 11 is constituted by a large number of through holes formed in the lower part of the partition panel 6.

In the machine room 7, a temperature adjusting means 12 for adjusting the temperature of the inside C, and a circulating air flow S
And a circulating means 13 for forming The temperature control means 12 is mainly constituted by a heat exchanger. The circulating means 13 is composed of a partition wall 14 mounted above the temperature control means 12 across the machine room 7 and a fan 15 provided on the partition wall 14, and the circulating air flow S is formed by the fan 15. It has become.

Below the fan 15, a humidifier (humidity adjusting means) 16 and a C
And a humidification duct 17 for communicating the same. The humidifier 16 supplies humidified air from the humidifier 16 to the interior C through the humidification duct 17 as needed, thereby adjusting the humidity of the interior C. Note that an opening 57 is provided above the fan 15 for returning a part of the humidified air in the inside C to the humidifier 16.

On the other hand, a ceiling duct 20 having a closed cross-sectional structure comprising an upper wall surface 18 of the interior C and a duct panel 19 disposed below the upper wall surface 18 is formed on the ceiling portion on the accommodation room 2 side. . One end of the ceiling duct 20 is communicated with the upper part of the machine room 7 through the above-described upper communication portion 10, and the other end is opened as an air outlet 20a.
The air outlet 20a is located inside the compartment C located on the side opposite to the machine room 7.
One side wall surface (in this example, it is located on the left side of the warehouse,
Hereinafter, this one side wall surface is referred to as a left side wall surface) 21 with a predetermined gap G interposed therebetween. Then, the air in the machine room 7 is blown into the accommodation room 2 from the air outlet 20 a through the ceiling duct 20.

As shown in FIGS. 3 and 4, a part of the air blown from the air outlet 20 a of the ceiling duct 20 is circulated downward along the left wall surface 21 on the left wall surface 21 of the interior C. A duct 22 is provided. The circulation duct 22 extends vertically along the left wall surface 21, and in the illustrated example, the depth dimension is set to be in a range of ２ to の of the depth dimension of the interior C. It is arranged at an intermediate position in the depth direction of the compartment C. Circulation duct 2
The upper end of the ceiling duct 2 is an air inlet 22a.
G or air outlet 20 between zero and left side wall 21
a. The lower end of the circulation duct 22 serves as an air outlet 22b, and is located at a substantially middle position in the height direction in the refrigerator. A humidity sensor 23 for detecting the humidity of the inside C is disposed immediately below the air outlet 22 b of the circulation duct 22, that is, at a position where air blown from the circulation duct 22 directly hits.

According to the bread-making temperature and humidity control cabinet 1 of the present invention constructed as described above, while the surrounding air is heated or cooled by the temperature control means 12 in the machine room 7, the fan Due to 15, an upward air flow (that is, an air flow S) is formed in the machine room 7. This air is
The air is sent from the upper part in the machine room 7 to the ceiling duct 20 on the accommodation room 2 side through the upper communication part 10 provided above the partition panel 6, and passes through the ceiling duct 20 to the left in FIG. After flowing, it is blown out from the air outlet 20a toward the vicinity of the upper portion of the left wall surface 21 in the storage chamber 2. A part of the blown air flows to the right partition panel 6 side across the accommodation room 2, and then is sucked into the machine room 7 from a lower communication portion 11 provided at a lower portion thereof. In this way, an airflow S is formed in which a part of the air blown out from the air outlet 20a of the ceiling duct 20 traverses the inside of the accommodation room 2 and circulates through the inside C.

The air blown out from the air outlet 20a of the ceiling duct 20 also flows downward along the left side wall 21 of the interior C. At this time, in the middle part of the interior C in the depth direction,
A part of the air flowing downward along the left wall surface 21 is blown downward through the circulation duct 22 from the lower end thereof, that is, the air outlet portion 22b located at a substantially intermediate height of the interior C. . Then, the partition panel 6 is sucked into the machine room 7 from the lower communication portion 11 mainly across the lower side in the storage room 2. In this way, an air flow S that circulates through the inside C of the storage chamber 2 mainly across the lower side is formed.

The temperature inside the refrigerator is made uniform by forming the air flow S which circulates evenly in the refrigerator C in this way, while, on the other hand, the humidifier 16 receives fine air from the humidifier 16 via the humidification duct 17, for example. Air containing mist, that is, humidified air, is supplied to the interior C as needed. This humidified air circulates through the inside C while diffusing on the airflow S. Thereby, the humidity in the refrigerator C is adjusted to be uniform and the predetermined humidity at the same time.

In such a bread-making temperature and humidity control cabinet 1, it is necessary to constantly monitor the humidity of the cabinet C in order to accurately control the humidity in the cabinet. For this reason, a humidity sensor 23 for detecting the humidity is provided in the refrigerator C. However, in a conventional bread temperature controlling humidity controller, accurate detection of the humidity in the refrigerator is difficult because the humidity sensor is easily dewed. In some cases, it is difficult to replace the humidity sensor.

However, in the baking temperature and humidity control cabinet 1 of the present invention, a circulation duct 22 for guiding a part of the air flow S downward is provided on the left side wall 21 of the cabinet C located on the opposite side of the machine room 7. A humidity sensor 23 is detachably provided directly below the air outlet 22b of the circulation duct 22. For this reason, the air blown out from the air outlet 22b of the circulation duct 22 always hits the humidity sensor 23, and the humidity sensor 23 is less likely to condense. Further, even if the humidity sensor 23 is condensed, the air outlet 22 of the circulation duct 22
Since the air blown out from b always hits the humidity sensor 23, the dew condensation portion dries relatively quickly. Thus,
Dew condensation of the humidity sensor 23 can be prevented or suppressed, and as a result, accurate detection of the humidity in the refrigerator can be performed.

The air flow S circulating in the inside C is detected by the humidity sensor 23.
, The humidity in the refrigerator is quickly detected, for example, even during humidification. Therefore, humidification overshoot and the like caused by delay in detection of the humidity in the refrigerator during humidification are reduced, and more accurate humidity control is possible.

Since the humidity sensor 23 is detachably mounted at a position directly below the air outlet 22b of the circulation duct 22, that is, at a predetermined position on the left wall 21 facing the storage chamber 2, where the work is easy. In addition, only the humidity sensor 23 can be easily removed or attached without removing the partition panel 6 as in a conventional baking temperature and humidity control cabinet. Thereby, the replacement work of the humidity sensor 23 is facilitated as compared with the related art.

[0032]

As described above, according to the temperature and humidity control cabinet for bread making of the present invention, the humidity in the cabinet is detected directly below or below the air outlet of the circulation duct provided on the left wall surface in the cabinet. Since the humidity sensor is detachably mounted, dew condensation on the humidity sensor can be prevented or suppressed.
Further, even when the humidity sensor forms dew, the air blown out from the circulation duct always hits the humidity sensor, so that the dew condensation of the humidity sensor is quickly eliminated.
As a result, accurate and prompt detection of humidity in the refrigerator and more accurate humidity control can be performed, and problems such as humidification overshoot can be solved.

Further, since the humidity sensor can be easily removed and attached without removing the partition panel in the refrigerator as in the conventional case, the replacement operation of the humidity sensor becomes easy.
