BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. The present embodiment shown in FIGS. 1 to 9 relates to a drying cabinet for drying and storing articles such as foods. This drying chamber is composed of a drying chamber 1 and a dehumidifying section 2 that processes the air in the drying chamber 1 into a dry atmosphere. The drying chamber 1 is configured as a drawer-type closed box structure that can be inserted into and removed from an outer box 3 having an open front surface, and an opening / closing lid 4 that can be opened and closed by rotating or sliding is attached to the upper part (see FIGS. 1 and 3). . Opening at the top
It is easy to put articles in and take them out from the drying chamber 1, and it is easy to use. As shown in FIG. 1, the front surface of the drying chamber 1 is composed of a front panel 5 that projects outward, and openings 6 are provided one on each side of the upper projecting portion. In a state where the drying chamber 1 is inserted in the outer box 3, two rows of ventilation passages 7 extending in the front-rear direction are provided in the center of the top plate between the opening / closing lid 4 of the drying chamber 1 and the top plate of the insertion part. It is defined by a partition 8 (see FIGS. 3 and 4). The two rows of ventilation passages 7 are respectively connected to the two openings 6 of the front panel 5 of the drying chamber 1.

The dehumidifying section 2 is composed of an adsorption dehumidifying device and is provided behind the drying chamber 1 in the outer box 3.
The adsorption / dehumidification device has a large number of linear passages 9 for passing air, and a dehumidifier 10 in a stationary state having a reversible moisture absorption / desorption function, and a blower 1 for ventilating the passages 9 of the dehumidifier 10.
An air passage 12 in which 1 and a heating means capable of raising the temperature of air passing through the dehumidifier 10 are incorporated in series is configured in a hexahedral outer shell 13 (see FIG. 2). The inlets 14 and 15 and the outlets 16 and 17 of the air passage 12 of the adsorptive dehumidifier are opened in a pair form on the two surfaces of the adjacent outer shell 13. Outer shell 1
In FIG. 3, a dehumidifying path from one inlet 14 to the one outlet 16 via the air passage 12, a regeneration path from the other inlet 15 to the other outlet 17 via the air passage 12 and a bypass 18 are provided. There is. The bypass 18 is configured as a path that bypasses the dehumidifier 10 and the heating means in the regeneration path,
The outlet 19 is opened in the same direction as the outlet 17 in the vicinity of the outlet 17 of the regeneration path.

At the inlets 14 and 15 and the outlets 16 and 17 of the dehumidifying route and the regenerating route and the outlet 19 of the bypass 18,
An airtight holding member is attached to each of the edges of the mouth, and is opened and closed by one opening / closing damper mechanism. The opening / closing damper mechanism has a configuration in which an inlet opening / closing blade 21, an outlet opening / closing blade 22, and a bypass opening / closing blade 23 are mounted in a line on the rotation shaft of a stepping motor 20, and when the regeneration path is opened, the bypass 18 is opened. , Dehumidification route is shut off.

Both the inlet 14 and the outlet 16 of the dehumidifying path are connected to the drying chamber 1 in an airtight state, and the inlet 15 and the outlet 17 of the regenerating path are connected to the two rows of ventilation passages 7 of the outer case 3, respectively. , The outsides of the drying chamber 1 are communicated with each other through the openings 6 of the front panel 5.

The dehumidifier 10 comprises a corrugated structure material and a honeycomb structure material, which are made by bonding a hygroscopic agent such as silica gel to inorganic fibers such as ceramics by utilizing a polymerization reaction,
A large number of linear passages 9 for passing the air to be treated are arranged in a rectangular parallelepiped shape. The passages 9 are parallel to each other, and the open ends of the passages 9 are open to two opposing surfaces of the dehumidifier 10.

As a heating means, as shown in FIG. 5, a heat-radiating plate 25 having rectangular ventilation holes 24 formed at equal intervals is coated with a plastic film having electrical insulation and heat resistance, which is highly efficient in heat. A safety structure is provided in which a temperature fuse and a thermostat are provided as a power disconnecting and disconnecting means in close contact with each other, and is installed in a state in which it crosses the air passage 12 in the preceding stage of the dehumidifier 10. A positive temperature coefficient thermistor can also be used as the heating means. Dehumidifier 10 and outer shell 13
A heat insulating air layer or a heat insulating structure 29 made of a heat insulating resin having a large amount of foam is provided between and to efficiently heat the dehumidifier 10 during regeneration.

The operations of the cord heater 26, the blower 11 and the stepping motor 20 are controlled by the control means 30 equipped with a microcomputer incorporated in the dehumidifying section 2. The control means 30 is shown in FIG.
Humidity sensor 31 provided in the drying chamber 1 as shown in FIG.
Is connected to the input side and the heater drive circuit 32 is connected to the output side.
In addition to the motor drive circuit 33 and the blower drive circuit 34, the setting means 35 and the operation display means 36 are connected.

In this drying chamber, the opening / closing damper mechanism alternately opens and closes the dehumidifying path and the regenerating path, and the dehumidifier 10 alternates between the dehumidifying process and the regenerating process so that the drying chamber 1 can have a dry atmosphere. . In the dehumidifying operation for dehumidifying the inside of the drying chamber 1, the stepping motor 20 is rotated, and the inlet 15 and the outlet 17 of the regeneration path and the outlet 19 of the bypass 18 are closed by the inlet opening / closing blade 21, the outlet opening / closing blade 22, and the bypass opening / closing blade 23. The operation is performed at room temperature by operating the blower 11. That is, a circulating air flow is formed in the drying chamber 1 by the open dehumidifying path, and each time the moisture passes through the dehumidifier 10, moisture is adsorbed to the dehumidifier 10 in a molecular state, so that the drying chamber 1 quickly becomes a dry atmosphere. .

Since the adsorption capacity of the dehumidifier 10 decreases as it adsorbs water molecules, a regenerating operation for regenerating the dehumidifier 10 in the regeneration process is performed. Regeneration of the dehumidifier 10
The stepping motor 20 is rotated, the inlet 14 and the outlet 16 of the dehumidifying path are closed by the inlet opening / closing blade 21 and the outlet opening / closing blade 22, and the outlet 1 of the bypass 18 is closed.
9 is opened, the blower 11 is operated, and the cord heater 26 is energized to carry out at a high temperature of about 140 ° C. That is, the air outside the refrigerator is sucked from the inlet 15 through the opening 6 of the front panel 5 by the opened reproduction path,
Water molecules in the dehumidifier 10 are released by being heated by passing through the heat dissipation plate 25 and passing through the passage 9 of the dehumidifier 10.
Part of the sucked outside air flows to the bypass 18 without passing through the heat dissipation plate 25, flows out from the outlet 19 and joins the regeneration path, and is dried from the outlet 17 through the ventilation passage 7 of the outer box 3. It is discharged from the opening 6 of the front panel 5 of the chamber 1 to the outside of the refrigerator. The air regenerated from the dehumidifier 10 is hot and humid, but since it mixes with the air at room temperature flowing through the bypass 18, the temperature of the air discharged outside the refrigerator is low. As a result, the obstruction of the indoor atmosphere of the installation location such as the kitchen is suppressed during reproduction.

By opening the dehumidifying path in the dehumidifier 10 thus regenerated and passing the air in the drying chamber 1, the moisture in the drying chamber 1 can be adsorbed again and the drying chamber 1 can be made into a dry atmosphere. . Between the dehumidifier 10 and the outer shell 13, there is an adiabatic air layer or an adiabatic structure 29 made of a poly-foamed adiabatic resin.

The control means 30 alternates the dehumidifying operation and the regenerating operation according to the control algorithm shown in the flow chart of FIG. 7 to perform the drying operation. That is, when the power is turned on, the control means 30 reads the output value D of the humidity sensor 31 in step # 1 in the flowchart of FIG. 7, and proceeds to step # 2 to set the output value D of the humidity sensor 31 in advance by the setting means 35. It is determined whether or not the set value D0 is set or more. Here, D0 is a value for a humidity of approximately 30%. If D ≧ D0, the process proceeds to step # 3,
Otherwise, the process returns to step # 1. Step #
At 3, the process for starting the regeneration operation and the process for starting the counting of the regeneration timer 37 constituted by the program of the microcomputer are carried out, and the routine proceeds to step # 4.
In step # 4, it is determined whether or not a predetermined time T1 has elapsed, and if it has elapsed, the process proceeds to step # 5. If not, the process of step # 4 is repeated.

In step # 5, the process of turning off the cord heater 26 is performed, and the process proceeds to step # 6. In step # 6, it is determined whether or not the predetermined time T2 has elapsed, and if it has elapsed, a process of stopping the blower 11 is performed in step # 7 and the process proceeds to step # 8. If not, step # 6
The process of is repeated. In step # 8, the process of starting the dehumidifying operation and the process of starting the count of the dehumidifying timer 38 configured by the program of the microcomputer are performed, and then the process proceeds to step # 9. At step # 9, the output value D of the humidity sensor 31 is differentiated to calculate the change rate ΔD, and the process proceeds to step # 10. In step # 10, it is determined whether or not the rate of change ΔD of the output value D of the humidity sensor 31 is 0. If the rate of change ΔD is 0, the process of step # 12 is performed to start the counting of the counter, and then step # 1
Go to 3. In step # 13, it is determined whether or not the count number N of the counter is, for example, five. If N = 5 times, the process returns to step # 3. If the change rate ΔD is not 0 in step # 10, the process proceeds to step # 11. Step #
At 11, it is determined whether or not the predetermined time T3 has elapsed, and if it has elapsed, the process returns to step # 1. If not, the process returns to step # 9. If N = 5 in step # 13, the counter is cleared, the operation is stopped in step # 14, and the operation stop is displayed on the operation display means 36 in step # 15.

If the output value D of the humidity sensor 31 does not change even after the dehumidifying operation, the opening / closing lid 4 of the drying chamber 1 may be left open, or the dehumidifying section 2 may be damaged, so the operation is stopped. Then, it is displayed on the operation display means 36 such as lighting of the LED or liquid crystal to inform the user. Where D
The value of 0 is set to a value corresponding to a humidity of about 30% in order to maintain the humidity in the drying chamber at about 30% and keep the food fresh. Water activity is the equilibrium relative humidity of water in food under the condition that the effect of water on the oxidation of oils and fats is the smallest, and the water activity is almost the same as the relative humidity of the ambient atmosphere.

In the alternation of the regenerating operation and the dehumidifying operation, the regenerative path and the dehumidifying path are switched by the opening / closing damper mechanism. At this time, the control means 30 causes the motor drive circuit 3 to operate.
The operating angle of the stepping motor 20 is determined from the shape of the outer shell 13 via the inlet / outlet ports 16, 17, 1
It is controlled to be larger than the closing angle of 4, 15 by about 7.5 degrees. Accordingly, the inlet opening / closing blade 21, the outlet opening / closing blade 22 and the bypass opening / closing blade 23 of the inlets 14 and 15 and the outlets 16 and 17 of the dehumidifying path and the regeneration path and the outlet 19 of the bypass 18 serve as an airtight holding member when closed. It is pressed and closed in a highly airtight state. The quality of the airtightness of this portion largely affects the efficiency of the drying cabinet, and if the airtightness is poor, it becomes difficult to form and maintain the dry atmosphere in the cabinet.

The moisture absorption capacity of the dehumidifier 10 is affected by temperature,
The lower the temperature, the higher the hygroscopic ability, but the force of adsorbing water molecules is the force of attraction between the hygroscopic material and water molecules. The capacity of the dehumidifier 10 to adsorb water molecules at room temperature is about 10% of its mass. However, when the inside of the drying chamber 1 is made into a dry atmosphere by alternating dehumidification and regeneration with ventilation for one dehumidifier 10, there is virtually no absorption of moisture until the dehumidifier 10 becomes saturated. However, if moisture is absorbed until it is close to the saturated state and then regeneration is started, it takes time and the dehumidification efficiency becomes extremely poor.
In the present embodiment, as a measure for improving efficiency, the predetermined time T3 in step # 11 is set as the time at which water molecules occupying about 5% of the mass of the dehumidifier 10 can be adsorbed. For example, if the mass of the dehumidifier 10 is 30 g, the predetermined time T3
Is set to 15 minutes. As a result, when the dehumidifier 10 absorbs the moisture most effectively, the dehumidifying operation can be performed and the dehumidifier 10 can efficiently absorb the moisture (see FIG. 8).

Regeneration of the dehumidifier 10 is to separate the adsorbed water molecules by heat and carry them out by blowing air, and the adsorbed water molecules violently move by the heat and are separated from the hygroscopic material. At this time, for example, the adsorption amount of water molecules having an air temperature of 80 ° C. in the dehumidifier 10 is about 1 of the mass of the dehumidifier 10.
It is about%. If the regenerating operation is performed until the water molecules in the dehumidifier 10 are almost completely exhausted, it takes time and the regeneration efficiency becomes extremely poor. In this embodiment, as a measure for improving the efficiency of the regeneration operation, the predetermined time T1 by the regeneration timer 37 in step # 4 is half the dehumidification operation time T3, ie, the time T3.
It is set to / 2, and when the dehumidifier 10 releases moisture most effectively, the regeneration operation is performed so that the dehumidifier 10 can be efficiently regenerated (see FIG. 9).

In step # 5, the cord heater 26
Is turned off and a predetermined time T2 (T1
By operating the blower 11 up to +1.5 minutes,
The dehumidifier 10 heated in the regeneration operation can be cooled to be in a state of having a high hygroscopic capacity and can be transferred to the dehumidification operation, and the efficiency at the time of alternation of the dehumidification operation and the regeneration operation, which are contradictory processes, is improved.

In step # 9, the output value D of the humidity sensor 31 is differentiated to calculate the change rate ΔD, and then step # 10.
The change rate ΔD is judged to be 0 or not. If the change rate ΔD is 0, the dehumidifying function is lowered and the dehumidifying operation of the dehumidifier 10 is almost stopped. Therefore, it is possible to shift to the regeneration operation, and the drying chamber 1 can be efficiently placed in a dry atmosphere. Although it is easier to set the criterion for the rate of change to 0, there is no practical problem if a numerical value close to 0 is used as the criterion.

This drying cabinet is suitable for storing dried foods, but can also be used for drying and storing articles other than foods, and for drying and processing articles such as production of dried flowers. With regard to the mechanical portion not related to the control, the opening / closing can be switched by a single opening / closing damper mechanism from the positional relationship between the inlets 14 and 15 and the outlets 16 and 17 of the dehumidifying route and the regeneration route and the outlet 19 of the bypass 18. It is possible to reduce the size of the drying cabinet and simplify the control system of the opening / closing damper mechanism.

Embodiment 2. This embodiment shown in FIG. 10 relates to an opening / closing damper mechanism for opening / closing the inlets 14 and 15 and the outlets 16 and 17 of the dehumidifying path and the regenerating path of the dehumidifying section 2 of the drying chamber shown in the first embodiment. The other configuration is the same as that of the first embodiment. Therefore,
The same parts as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

In the drying chamber of the present embodiment, the inlets 14 and 15 and the outlets 16 and 17 of the dehumidifying route and the regenerating route are as shown in FIG.
It is opened and closed by two independent opening and closing damper mechanisms as shown in 0. Each opening / closing damper mechanism is configured such that an inlet opening / closing blade 21, an outlet opening / closing blade 22, and a bypass opening / closing blade 23 are attached to each arm rotated by each stepping motor 20. By using two opening / closing damper mechanisms in this way, the inlet opening / closing blade 21
The engagement with the inlets 14 and 15 and the engagement of the outlet opening / closing blade 22 with the outlets 16 and 17 can be ensured. Since the connecting shaft that penetrates the heat insulating structure 29, the outer shell 13, and the blower 11 can be eliminated, the structure can be simplified and air leakage from the penetrating portion can be eliminated. The two stepping motors 20 are operated sequentially or in parallel. As a result, the drive circuit of each stepping motor 20 can be configured by a single circuit, and cost reduction and operational reliability can be obtained.
