Patent Document 1: Japanese Laid-Open Patent Publication No. 2014-64827

However, the load applied to the air blowing device of the dryer described in Patent Document 1 varies depending on the weight and size of the quilt, and in order to efficiently dry the cotton, it is necessary to adjust the air blowing amount of the air blowing device for each quilt. . For example, when the dryer described in Patent Document 1 in which the air supply amount has been adjusted according to the weight of the heavy cotton quilted filled with cotton is used for a lightweight quilt filled with feathers, the air blowing amount is larger than the load applied to the air blowing device. Therefore, at the end on the opposite side to the side where the dryer is disposed, a gap is formed between the pad and the quilt, so that hot air leaks from this slit. The leaking hot air does not contribute to the drying of the quilt, so that when there is a gap, the drying efficiency is deteriorated. Further, for example, when the dryer described in Patent Document 1 in which the air supply amount has been adjusted according to the increase in the size of the single person is used for a quilt of a standard single size, the same is because the air supply amount is larger than that applied to the air supply. The load of the device causes the hot air to leak out. As described above, in the past, as described in Patent Document 1, it is impossible to efficiently dry cotton quilts having different weights or sizes by one machine.

The present invention has been made in view of the above problems, and an object thereof is to provide a baking machine capable of efficiently drying a cotton having a different weight or size and a different applied load by one machine.

The dryer of the present invention includes a casing, a blower, and a blower control unit that controls the blower. An intake port, an air outlet, and an air passage connecting the intake port and the air outlet are formed in the casing. The air blowing device is disposed in an air passage formed in the casing, and performs air blowing from the air inlet to the air outlet. The air blowing device control unit controls the air blowing device to reduce the air blowing amount of the air blowing device when the air blowing amount of the air blowing device is excessively large with respect to the load applied to the air blowing device.

In the drying machine of the present invention, when the air blowing amount of the air blowing device is excessively large with respect to the load applied to the air blowing device, the air blowing device is controlled to reduce the air blowing amount of the air blowing device. In the baking machine of the present invention, when the amount of blown air is excessively large with respect to the load, the amount of blown air is reduced in accordance with the load, so that hot air leakage can be suppressed, and the weight or size can be efficiently different by one machine. The quilts of different loads are dried.

The dryer 1 includes a casing 2, a blower 3 (corresponding to the air blowing device of the present invention), a heater 4, a wind pressure sensor 5, a control unit 7, and a plurality of window vanes 6.

The casing 2 is composed of a hollow body portion 21 having a side surface formed with an intake port 23 as an opening connected to the internal space 21a, and a tubular-shaped blowing portion 22 having one end portion integrated with the body portion 21, An air outlet 24 as an opening connected to the internal space 22a is formed at the other end. Body portion 21 The internal space 21a is connected to the internal space 22a of the blowing portion 22, and the internal space 21a, 22a forms an air passage 25 connected to the air outlet 24 from the air inlet 23 through the internal space 21a, 22a.

An operation portion 26 is provided on the upper surface of the body portion 21. The user can perform the operation start and the operation stop of the dryer 1 at least by operating the operation unit 26. In the first embodiment, the operation unit 26 is of a dial type, and the user can change the position of the dial to change the operation of the dryer 1 to start the operation and stop the operation. Further, the operation unit 26 may be a switch type that is not a dial type, and has a switch, and the user can perform an operation of starting and stopping the operation of the dryer by pressing the switch.

Further, a handle 27 is provided in the blowing portion 22. The handle 27 is composed of a long-length portion 27a which is disposed on both side faces of the blowing portion 22, and a longitudinal direction extending in a direction slightly perpendicular to the opening surface of the air outlet 24; a grip portion 27b which will have a long-length portion 27a The end on the side of the air outlet 24 is connected to the upper side of the blowing portion 22. As shown in FIG. 3, the side surface of the blowing portion 22 is structured such that the long-length portion 27a can move in a direction slightly perpendicular to the opening surface of the air outlet 24. In this configuration, for example, a groove perpendicular to the opening surface of the air outlet 24 may be formed on the side surface of the blowing portion 22, and a protrusion protruding toward the blowing portion 22 may be formed at the end portion of the long-length portion 27a on the main body portion 21 side, wherein the long length portion The protrusion of 27a is inserted into the groove and can move along the groove of the blowing portion 22.

A blower 3, a heater 4, a wind pressure sensor 5, a control unit 7, and a window vane 6 are provided inside the casing 2, respectively. The blower 3 is installed in the air passage 25, and when it operates, an air flow from the intake port 23 toward the air outlet 24 is generated in the air passage 25, and air is blown from the intake port 23 to the air outlet 24. Therefore, when the blower 3 is shipped At the time of turning, the air is sucked from the intake port 23, and the sucked air passes through the air passage 25 and is blown out by the air outlet 24. In the first embodiment, the blower 3 is composed of a fan 31 provided in the air passage 25 and a fan motor 32 for rotating the fan 31. When electric power is supplied to the fan motor 32, the fan 31 rotates and is driven by the fan 31. The air flow from the intake port 23 toward the air outlet 24 is generated in the air path 25 by the rotation. Further, the amount of air flowing from the intake port 23 toward the air outlet 24 is referred to as a blow amount Q.

The heater 4 is disposed in the air passage 25, and when it operates, the air in the air passage 25 is heated. In the first embodiment, the heater 4 is a PTC (Positive Temperature Coeffcient) heater or a nickel-chromium electric heating wire heater, and when the electric power is supplied thereto, heat can be generated, and the air in the air passage 25 can be heated. Further, in the drying machine 1, by simultaneously operating the blower 3 and the heater 4, the air sucked from the air inlet 23 by the blower 3 can be heated by the heater 4, and the heated air can be blown out from the air outlet 24 as Hot air.

The wind pressure sensor 5 is disposed in the air passage 25 and is a sensor that measures the wind pressure value H of the airflow generated by the blower 3. Further, in general, the wind pressure value is proportional to the square of the wind speed, and therefore, the wind pressure sensor 5 may be replaced with an air speed sensor that measures the wind speed in the air passage 25.

The window vane 6 is a plate-shaped member which is provided in the vicinity of the air outlet 24 and is disposed to be slightly perpendicular to the opening surface of the air outlet 24. By providing the window vanes 6, the hot air blown from the air outlet 24 can be made straight. Furthermore, the window vane 6 is disposed closer to the blowout port 24 than the wind pressure sensor 5.

Fig. 4 is a block diagram of the dryer of the first embodiment. The control unit 7 is provided inside the main body unit 21 and includes at least an operation information acquisition unit 71, a wind pressure value acquisition unit 72, a memory unit 73, a wind pressure value determination unit 74, and a blower control. The unit 75 (corresponding to the air blower control unit of the present invention), the heater control unit 76, and the timer 77. The control unit 7 corresponds to, for example, a microcontroller.

The operation information acquisition unit 71 is connected to the operation unit 26, and acquires information that has been operated by the user in the operation unit 26. Further, the operation unit 26 may be directly provided in the control unit 7, and the operation unit 26 and the operation information acquisition unit 71 may be integrated.

The wind pressure value acquisition unit 72 is connected to the wind pressure sensor 5, and obtains the wind pressure value H measured by the wind pressure sensor 5. In addition, the time point at which the wind pressure value acquisition unit 72 acquires the wind pressure value H is based on the elapsed time T measured by the timer 77 to be described later.

The memory unit 73 stores at least the threshold wind pressure change amount ΔHT (corresponding to the first threshold wind pressure change amount ΔHT1 of the present invention) and the past wind pressure value Hb. Such a memory portion 73 can be, for example, a memory. The threshold wind pressure change amount ΔHT is a preset positive value used when the wind pressure value determining unit 74 to be described later determines whether or not the blow air amount Q of the blower 3 is excessively large. The method of determining the threshold wind pressure change amount ΔHT may be a method of determining the specific value by the manufacturer of the dryer 1 or a method determined by the user using the operation unit 26. In addition, the past wind pressure value Hb is a wind pressure value acquired by the past wind pressure value acquisition unit 72, and is a value updated at an arbitrary time point.

The wind pressure value determining unit 74 determines whether or not the air blowing amount Q of the air blower 3 is excessively large with respect to the load, and the determination is based on the wind pressure value H obtained by the wind pressure value acquiring unit 72 and the threshold wind pressure amount stored in the memory unit 73. △ HT and the past wind pressure value Hb. Specifically, the wind pressure value determining unit 74 calculates the wind pressure change amount ΔH (that is, the difference between the wind pressure value H and the past wind pressure value Hb) based on the calculation formula of ΔH=Hb-H, and calculates the calculated The wind pressure change amount ΔH is compared with the threshold wind pressure change amount ΔHT, and it is judged whether or not the condition of ΔH≧ΔHT is satisfied. The wind pressure value determining unit 74 determines the air blowing amount Q of the air blower 3 with respect to the load when the condition is satisfied (ΔH ≧ ΔHT). If it is too large, when the condition is not satisfied (ΔH < ΔHT), it is judged that the blow amount Q of the blower 3 is appropriate with respect to the load. In addition, the reason why it is possible to determine whether or not the air blowing amount Q is excessive with respect to the load can be determined by judging whether or not the condition of ΔH ≧ Δ is satisfied, and will be described later in the description of the operation of the drying machine 1 to be described later.

The blower control unit 75 performs control of the blower 3 based on the information of the operation acquired by the operation information acquisition unit 71 and the determination result of the wind pressure value determination unit 74. Specifically, the blower control unit 75 has a switching element such as a controllable rectifier, controls the ratio or phase of the on/off time of the switching element to change the voltage and current supplied from the power source 100, and supplies it to the fan motor 32 of the blower 3, Thereby, the operation of the blower 3 is controlled. The power source 100 here may be, for example, a commercial power source or a battery, and the dryer 1 has an electric wire that electrically connects the blower control unit 75 and the power source 100. Further, the blower control unit 75 can change the voltage value V supplied to the fan motor 32 to a preset plurality of set voltage values, and in the first embodiment, can be changed to the first set voltage value V11 and the second set voltage value. The three stages of V12 and the third set voltage value V13 are set to values satisfying the relationship of V11>V12>V13. Further, the air blowing amount Q of the air blower 3 is such that the larger the number of rotations of the fan 31 is, the larger the air blowing amount Q is, and the higher the voltage value V supplied to the fan motor 32 is, the larger the number of rotations of the fan 31 is, so that it is supplied to the fan. The higher the voltage value V of the motor 32 is, the larger the blow air amount Q of the blower 3 is.

The heater control unit 76 performs control of the heater 4 based on the information of the operation acquired by the operation information acquisition unit 71. Specifically, the heater control unit 76 is a switch, and during the operation of the dryer 1, the electric power from the power source 100 is supplied to the heater 4 to heat the heater 4, and the air in the air passage 25 is heated. During the period in which the dryer 1 is stopped, the shutdown from the power source 100 is stopped. Power is supplied to the heater 4.

The timer 77 performs the measurement of the elapsed time T, and determines whether or not the elapsed time T has exceeded the sampling time TB (T ≧ TB) as the preset time. Further, when the timer 77 determines that the elapsed time T has exceeded the sampling time TB (T≧ TB), the elapsed time T is reset, and the elapsed time T is measured again.

Fig. 5 is a flow chart showing the air supply amount control of the dryer of the first embodiment. The air supply amount control of the drying machine 1 will be described. Further, at the beginning of Fig. 5, the fan motor 32 of the blower 3 is not driven, and the dryer 1 is in a stopped state.

First, in step S1, the user operates the operation unit 26 to start the operation of the dryer 1. After the end of step S1, step S2 is executed. In step S2, the operation information acquisition unit 71 acquires the information of the operation of step S1. After the process of step S2 is completed, step S3 is performed. In step S3, the blower control unit 75 operates the blower 3, and the heater control unit 76 operates the heater 4. Further, in step S3, the blower control unit 75 performs control so that the voltage value V supplied to the fan motor 32 is the first set voltage value V11 at which the blow air amount Q is the largest among the set voltage values.

After the process of step S3 is completed, the process proceeds to step S4. In step S4, the wind pressure value acquisition unit 72 acquires the wind pressure value H measured by the wind pressure sensor 5. After the process of step S4 is completed, step S5 is performed. In step S5, the memory unit 73 re-stores the wind pressure value H obtained in step S4 as the past wind pressure value Hb.

After the process of step S5 is completed, step S6 is performed. In step S6, the timer 77 resets the elapsed time T and starts measuring the elapsed time T. After the process of step S6 is completed, step S7 is performed. In step S7, the timer 77 determines the elapsed time T and the elapsed time T in order to determine whether the elapsed time T has exceeded the sampling time TB. The sample time TB is compared to determine whether the condition of T≧TB is satisfied. In step S7, the result of the comparison is T < TB, and the timer 77 determines that the elapsed time T has not exceeded the sampling time TB (NO in step S7), and returns to the determination in step S7. In step S7, the result of the comparison is T≧TB, and the timer 77 determines that the elapsed time T has exceeded the sampling time TB (YES in step S7), and proceeds to step S8.

In step S8, the wind pressure value acquisition unit 72 acquires the wind pressure value H measured by the wind pressure sensor 5. After the process of step S8 is completed, the process proceeds to step S9. In step S9, the wind pressure value determination unit 74 calculates the wind pressure change amount ΔH based on the calculation formula of ΔH=Hb-H, which is obtained in step S8. The difference between the wind pressure value H and the past wind pressure value Hb memorized by the memory unit 73 in step S5 or step S14 described later. In other words, in step S9, the wind pressure value H obtained by the wind pressure value acquisition unit 72 is subtracted from the wind pressure value H obtained by the wind pressure value acquisition unit 72, thereby calculating the period of the sampling time TB. The amount of change in wind pressure is ΔH. After the process of step S8 is completed, step S10 is performed. In step S10, the wind pressure value determining unit 74 compares the wind pressure change amount ΔH calculated in step S9 with the threshold wind pressure change amount ΔHT memorized by the storage unit 73. It is judged whether or not the condition of ΔH≧ΔHT is satisfied, thereby judging whether or not the blow air amount Q of the blower 3 is excessive with respect to the load.

When the condition of ΔH≧ΔHT is satisfied in step S10 (YES in step S10), that is, if the blow-up amount Q of the blower 3 is excessively large with respect to the load, step S11 is performed. In step S11, the blower control unit 75 performs control so that the blow air amount Q of the blower 3 is lowered. Specifically, when the current voltage value V is the first set voltage value V11, the blower control unit 75 lowers the voltage value V after the control to the second set voltage value V12 or the like, and reduces the voltage value supplied to the fan motor 32. V. After the processing of step S11 is finished, the step is performed. In step S12, in step S12, the blower control unit 75 determines whether or not the amount of air blown by the blower 3 can be further lowered. Specifically, the blower control unit 75 determines that the current voltage value V has been set to the minimum third set voltage value V13 among the set voltage values, and the voltage value V supplied to the fan motor 32 can no longer be lowered. The amount of air supplied can no longer be reduced. In step S12, when the blower control unit 75 determines that the amount of blown air can be further reduced (NO in step S12), step S13 is performed. In step S13, the wind pressure value obtaining unit 72 obtains the wind pressure sensor 5 to measure it. Wind pressure value H. After the process of step S13 is completed, the process proceeds to step S14. In step S14, the memory unit 73 re-stores the wind pressure value H obtained in step S13 as the past wind pressure value Hb. After the process of step S14 is completed, the process returns to step S6, and the timer 77 resets the elapsed time T again and restarts the measurement of the elapsed time T.

When the blower control unit 75 determines that the amount of blown air cannot be reduced again (YES in step S12), the blower amount control is ended, and the blower 1 continues the operation while the blower amount of the blower 3 is the smallest.

When the condition of ΔH≧ΔHT is not satisfied in step S10 (step S10, NO), that is, when the blow air amount Q of the blower 3 is appropriate with respect to the load, step S14 is performed. In step S14, the memory unit 73 newly stores the wind pressure value H obtained in step S8 as the past wind pressure value Hb. After the process of step S13 is completed, the process returns to step S6, and the timer 77 resets the elapsed time T again and restarts the measurement of the elapsed time T.

Time chart of the amount of air supply Q. Next, the operation at the time of use of the dryer 1 will be described using the flowcharts of FIG. 5, the perspective views of FIG. 6, and the timing charts of FIGS. 7 to 9. Furthermore, in the time charts of FIGS. 7 to 9 , the specific times of the action description are referred to as time T0 and time T1, respectively. . . Time T14. In addition, the wind pressure value H at each time is called the wind pressure value H0 and the wind pressure value H1. . . Wind pressure value H14, the voltage value V at each time is called voltage value V0, voltage value V1. . . The voltage value V14, the air supply amount Q at each time is called the air supply amount Q0 and the air supply amount Q1. . . Air supply amount Q14.

First, as shown in Fig. 6, the user generally inserts the blowing portion 22 of the baking machine 1 between the mattress 200 and the quilt 300. Further, the user does not insert the body portion 21 of the dryer 1 between the mattress 200 and the quilt 300. By configuring the dryer 1 such that the air blown from the air outlet 24 is blown to the space between the mattress 200 and the quilt 300, the air inlet 23 sucks the air around the mattress 200 and the quilt 300 without Air is drawn in from the space between the mattress 200 and the quilt 300. Further, the dryer 1 is inserted from the end of the mattress 200 or the quilt 300, and the end portion into which the dryer 1 is inserted is referred to as a set side end portion 14, and the end portion on the opposite side to the side end portion 14 is provided. It is referred to as the opposite side end portion 15.

Next, the user operates the operation unit 26 to start the operation of the dryer 1 (step S1). Here, the time when the user starts the operation of the drying machine 1 is taken as the time T0 of the time chart of FIGS. 7 to 9. When the user operates the operation unit 26, the operation information acquisition unit 71 acquires information of the operation (step S2), the blower control unit 75 operates the blower 3, and the heater control unit 76 operates the heater 4 (step S3). The blower control unit 75 increases the voltage value V supplied to the fan motor 32, and reaches the first set voltage value V11 at time T1. Before the process of step S11, the voltage value V is maintained at the first set voltage value V11. Further, as the voltage value V increases, the air blowing amount Q and the wind pressure value H also increase.

When the blower 3 and the heater 4 perform the operation, the blower 3 takes in air from the intake port 23, and the sucked air flows through the air passage 25 and is heated by the heater 4, and the heated air is blown out from the blower outlet 24 into hot air. The dryer 1 dries the mat 200 and the quilt 300 by the hot air blown from the air outlet 24.

After the operation of the blower 3 and the heater 4 is started, the wind pressure value acquisition unit 72 acquires the wind pressure value H1 measured by the wind pressure sensor 5 at time T1 (step S4). In addition, the memory unit 73 re-stores the wind pressure value H1 at the time T1 acquired by the wind pressure value acquisition unit 72 as the past wind pressure value Hb (step S5).

Next, the timer 77 resets the elapsed time T and restarts the measurement of the elapsed time T (step S6). When the time T2 is reached (the time when the time T1 has elapsed after the sampling time TB has elapsed), since the condition of T≧TB is satisfied (YES in step S7), the wind pressure value obtaining unit 72 acquires the wind pressure sensor at time T2. 5 measured wind pressure value H2 (step S8).

Then, the wind pressure value determining unit 74 is based on the wind pressure value H2 at the time T2 acquired by the wind pressure value obtaining unit 72 and the wind pressure value H1 at the time T1 when the memory unit 73 is stored as the past wind pressure value Hb, based on The calculation formula of ΔH12=H1-H2 calculates the wind pressure change amount ΔH12 from time T1 to time T2 (step S9). According to Fig. 7, the wind pressure value H2 at time T2 is higher than the wind pressure value H1 at time T1. This is because when the hot air blown from the air outlet 24 advances toward the opposite end portion 15, the hot air pushes up the quilt 300 to form an air path from the air outlet 24 toward the opposite end portion 15, and the air path passes through the hot air. Widening, the area of the quilt 300 is increased, so that the load applied to the blower 3 is also increased, and the wind pressure value H is also negative. Increased by the load. Therefore, the wind pressure change amount ΔH12 is a negative value, and the threshold wind pressure change amount ΔHT that is not full is positive, and the wind pressure value determining unit 74 determines that the condition of ΔH≧ΔHT is not satisfied, and the blow air amount Q is relative to The load is appropriate (step S10, No). Then, the memory unit 73 newly stores the wind pressure value H2 at the time T2 as the past wind pressure value Hb (step S14), and the timer 77 resets the elapsed time T and restarts the measurement of the elapsed time T (step S6).

When the time T3 is reached (the time after the sampling time TB has elapsed from the time T2), since the condition of T≧TB has been satisfied (YES in step S7), the wind pressure value obtaining unit 72 acquires the wind pressure sensor at time T3. The measured wind pressure value H3 is 5 (step S8). Then, the wind pressure value determining unit 74 is based on the wind pressure value H3 at the time T3 acquired by the wind pressure value obtaining unit 72 and the wind pressure value H2 at the time T2 when the memory unit 73 is stored as the past wind pressure value Hb. The wind pressure change amount ΔH23 from the time T2 to the time T3 is calculated based on the calculation formula of ΔH23=H2-H3 (step S9).

Here, the amount of blown air Q when the dryer 1 is supplied to the fan motor 32 at the first set voltage value V11 is excessively large with respect to the load applied by the quilt 300, and during the period from time T2 to time T3, The air path formed by the hot air blown from the air outlet 24 to the quilt 300 reaches the opposite side end portion 15, and the hot air lifts up the opposite side end portion 15 of the quilt 300, and a gap is formed between the mattress 200 and the quilt 300. The hot air leaks from the space between the pad 200 and the quilt 300 through the slit, causing the hot air to leak, so the load applied to the blower 3 is greatly reduced. As shown in Fig. 7, the wind pressure value H is greatly reduced, and As shown in Fig. 9, the amount of blown air Q maintained at a constant value from time T1 increases. In addition, the leaking hot air does not contribute to the drying of the mat 200 and the quilt 300, so the generation of the gap may deteriorate the drying efficiency.

However, in the baking machine 1 of the first embodiment, the wind pressure value is judged. The wind pressure change amount ΔH23 calculated by the unit 74 is equal to or greater than the threshold wind pressure change amount ΔHT, so that the condition of ΔH ≧ Δ WR is satisfied, and the wind pressure value determining unit 74 determines that the blow air amount Q is excessive with respect to the load (step In S10, YES, the blower control unit 75 controls so that the voltage value V supplied to the fan motor 32 is lowered from the first set voltage value V11 to the second set voltage value V12 so that the blow air amount Q of the blower 3 is lowered (step S11). ). During the period from time T3 to time T4, the voltage value V is lowered to the second set voltage value V12 to reduce the amount of blown air. Therefore, the blow amount Q at the time point T4 is appropriate with respect to the load generated by the quilt 300. Therefore, the gap between the pad 200 and the quilt 300 disappears without further hot air leakage.

Therefore, in the drying machine 1 of the first embodiment, it is possible to determine that the air blowing amount Q is excessively large with respect to the load of the quilt 300 by the comparison of the wind pressure change amount ΔH and the threshold wind pressure change amount ΔHT. And the fact that there is a gap between the pad 200 and the quilt 300. Further, in the dryer of the first embodiment, when it is determined that the amount of blown air Q is excessively large with respect to the load of the quilt 300, the amount of blown air Q is decreased, and the between the mat 200 and the quilt 300 can be made. The gap disappears, and the hot air leakage is stopped, and the cotton quilt can be efficiently dried.

The blower control unit 75 can set the third set voltage value V13 smaller than the second set voltage value V12, and can further reduce the blow air amount Q (NO in step S12). Therefore, the wind pressure value acquisition unit 72 acquires the time T4. The wind pressure value H4 measured by the wind pressure sensor 5 (step S13), the memory unit 73 re-stores the wind pressure value H4 at the time T4 as the past wind pressure value Hb (step S14), and the timer 77 resets the passage. The time T is measured and the elapsed time T is measured again (step S6).

The time point from time T4 to time T9 is separated by the sampling time TB, respectively, and between the respective time points (for example, between T4 and T5), the flow of FIG. 5 is performed. A series of processes from step S6 to step S14 of the flowchart. As shown in Fig. 7, the wind pressure values H4 to H9 are substantially the same, so that the condition of ΔH ≧ Δ HT is not satisfied (step S10, No), the air supply amounts Q4 to Q9 are also substantially the same, and the voltage values V4 to V9 are also Roughly the same.

During the period from time T4 to time T9, the dryer 1 blows hot air between the mat 200 and the quilt 300, so that the moisture contained in the mat 200 and the quilt 300 evaporates and is dried. The quilt 300 becomes lighter as the moisture contained in the quilt 300 evaporates, and the load applied to the blower 3 by the quilt 300 is proportionally reduced with the amount of water evaporated. Therefore, the air supply amount Q that has been reduced between the time T3 and the time T4, as the quilt 300 is dried, the air supply amount Q becomes too large for the load of the quilt 300, at time T9 and time T10. In between, a gap is created between the mattress 200 and the quilt 300 again.

However, in the baking machine 1 of the first embodiment, the series of processes from step S6 to step S13 of the flowchart of Fig. 5 is continued. Therefore, the wind pressure value obtaining unit 72 acquires the wind pressure sensor at time T10. The measured wind pressure value H10 (step S8) is calculated based on the wind pressure value H3 and the wind pressure value H9 when the memory unit 73 memorizes the time T9 of the past wind pressure value Hb, based on the calculation formula of ΔH910=H9-H10. The wind pressure change amount ΔH910 during the period from the time T9 to the time T10 (step S9), the calculated wind pressure change amount ΔH910 is larger than the threshold wind pressure change amount ΔHT, so the wind pressure value determining unit 74 determines that the blow air amount Q is relatively When the load is too large (YES in step S10), the blower control unit 75 controls to lower the voltage value V supplied to the fan motor 32 from the second set voltage value V12 to the third set voltage value V13 so that the blower 3 blows air. Q is further lowered (step S11).

Therefore, the baking machine 1 of Embodiment 1 is cotton during the drying process. When the amount of water of 300 is reduced and a gap is formed between the pad 200 and the quilt 300 to make the drying efficiency low, the amount of blown air Q is further lowered, so that between the pad 200 and the quilt 300 can be made. The gap disappears and the hot air is prevented from leaking, so that the cotton quilt can be efficiently dried.

Since there is no set voltage lower than the third set voltage value V13, the blower control unit 75 cannot set the voltage value smaller than the third set voltage value V13, and the air blow amount Q cannot be further reduced (YES in step S12), so the end is completed. In the air supply amount control, the dryer 1 continues to operate in a state where the third set voltage value V13 is supplied to the fan motor 32.

As described above, in the dryer 1 of the first embodiment, when the wind pressure change amount ΔH (the amount of change in the period of the sampling time TB of the wind pressure value H) is larger than the predetermined threshold wind pressure change amount ΔHT, the blower is lowered. 3 air supply. Therefore, the drying machine 1 of the first embodiment can detect the fact that the gap between the mat 200 and the quilt 300 is generated and the hot air leaks due to the wind pressure change amount ΔH, and the air blow amount of the blower 3 can be reduced. And eliminate the gap. Therefore, in the baking machine 1 of the first embodiment, it is possible to efficiently dry the quilts having different weights or sizes and different loads applied to the air blowing device by one machine.

Further, in the dryer 1 of the first embodiment, the set voltage value that the blower control unit 75 can control has three stages, but the limit value is not limited thereto, and the set voltage value may be two or four or more, as long as it can be changed. The voltage value V is sufficient.

Further, in the drying machine 1 of the first embodiment, the occurrence of hot air leakage is detected based on the wind pressure change amount ΔH (the amount of change in the wind pressure value H during the sampling time TB), but this is not Limited. In the first modification and the second modification of the first embodiment, values other than the wind pressure change amount ΔH will be described. To detect an example of the occurrence of a hot air leak. In the first modification and the second modification of the first embodiment, the difference is in the configuration corresponding to the wind pressure sensor 5, the wind pressure value acquisition unit 72, and the wind pressure value determination unit 74, and There is control for detecting the occurrence of hot air leakage, and other configurations and controls are substantially the same as those of the first embodiment, and thus the description thereof will be omitted.

First modification of the first embodiment

Fig. 10 is a block diagram showing a baking machine according to a first modification of the first embodiment. First, the configuration of the baking machine 1a according to the first modification of the first embodiment will be described. In the oven 1a of the first modification of the first embodiment, the current sensor 5a is provided in place of the wind pressure sensor 5, and has a current value acquisition unit 72a instead of the wind pressure value acquisition unit 72, and has a current value determination unit. 74a is substituted for the wind pressure value determining unit 74. In the first modification of the first embodiment, the memory unit 73 stores at least the threshold current change amount ΔIT (corresponding to the first threshold current change amount ΔIT1 of the present invention) and the past current value Ib. The threshold current change amount ΔIT is a positive value set in advance by the manufacturer or the user, and the past current value Ib is a current value that the current value acquisition unit 72a has acquired in the past.

The current sensor 5a is a sensor that measures the current value I of the fan motor 32 supplied to the blower 3.

The current value acquisition unit 72a is connected to the current sensor 5a, and acquires the current value I measured by the current sensor 5a. In addition, similarly to the wind pressure value acquisition unit 72, the time point at which the current value acquisition unit 72a obtains the current value I is based on the elapsed time T measured by the timer 77 to be described later.

The current value determination unit 74a determines whether or not the air supply amount Q of the air blower 3 is excessive with respect to the load, and the determination is based on the current value I obtained by the current value acquisition unit 72a and the threshold current change amount ΔIT and the memory stored in the memory unit 73. The current value Ib is the same. Specifically, the current change amount ΔI (that is, the difference between the current value I and the past current value Ib) is calculated according to the calculation formula of ΔI=Ib-I, and the calculated current change amount ΔI and the threshold current are changed. The amount ΔIT is compared to determine whether the condition of ΔI ≧ ΔIT is satisfied. When the condition is satisfied (ΔI ≧ ΔIT), the current value determining unit 74a determines that the blow air amount Q of the blower 3 is excessively large with respect to the load, and determines that the blower amount of the blower 3 is not satisfied when the condition is not satisfied (ΔI < ΔIT). Q is appropriate with respect to load.

Fig. 11 is a flow chart showing the air supply amount control of the dryer according to the first modification of the first embodiment. Next, the air supply amount control of the dryer 1a according to the first modification of the first embodiment will be described. In the initial stage of Fig. 11, the dryer 1a is in a stopped state. The processing of steps S1a to S3a is the same as the processing of steps S1 to S3 of the first embodiment, and the description thereof will be omitted.

After the process of step S3a is completed, step S4a is performed, and in step S4a, the current value acquisition unit 72a obtains the current value I measured by the current sensor 5a. After the process of step S4a is completed, step S5a is executed. In step S5a, the memory unit 73 re-stores the current value I obtained in step S4a as the past current value Ib.

After the processing of step S5a is completed, step S6a is executed. In step S6a, as in step S6 of the first embodiment, the elapsed time T is reset and the measurement of the elapsed time T is restarted. After the processing of step S6a is completed, step S7a is performed. In step S7a, as in step S7 of the first embodiment, the elapsed time T and the sampling time TB are compared to determine whether or not the condition of T≧TB is satisfied. If it is determined in step S7a that the condition is not satisfied (NO in step S7a), the process returns to the determination in step S7a, and when it is determined that the condition is satisfied (YES in step S7a), step S8a is performed.

In step S8a, the current value acquisition unit 72a acquires the current value I measured by the current sensor 5a. After the processing of step S8a is completed, the steps are performed. In step S9a, the current change amount ΔI is calculated based on the calculation formula of ΔI=Ib-I, which is the current value I obtained by the current value acquisition unit 72a and the memory unit 73 in step S5a or step S14a to be described later. The difference in the past current value Ib that has been memorized. In other words, in step S9a, the current value I obtained by the current value obtaining unit 72a is subtracted from the current value I obtained by the current value obtaining unit 72a, and the current value I during the sampling time TB is calculated. △I. After the process of step S9a is completed, the process proceeds to step S10a. In step S10a, the current value determination unit 74a compares the current change amount ΔI calculated in step S9a with the threshold current change amount ΔIT stored in the memory unit 73, and determines Δ. Whether the condition of I ≧ ΔIT is satisfied.

When the condition of ΔI ≧ ΔIT is satisfied in step S10a (YES in step S10a), step S11a is performed. In step S11a, as in step S11 of the first embodiment, the blower control unit 75 performs control so that the blower is provided. The air supply amount Q of 3 is lowered. After the process of step S11a is completed, the process proceeds to step S12a. In step S12a, the blower control unit 75 determines whether or not the amount of air blown by the blower 3 can be further lowered. When the blower control unit 75 determines that the amount of blown air can be further lowered (step S12a, NO), the process proceeds to step S13. In step S13a, the current value obtaining unit 72a obtains the measured by the current sensor 5a. Current value I. After the process of step S13a is completed, the process proceeds to step S14a. In step S14a, the memory unit 73 re-stores the current value I obtained in step S13a as the past current value Ib. After the process of step S14a is completed, the process returns to step S6a.

When the blower control unit 75 determines that the amount of blown air cannot be reduced again (YES in step S12a), the blower amount control is ended, and the blower 1a continues the operation while the blower amount of the blower 3 is the smallest.

In step S10a, when the condition of ΔI ≧ ΔIT is not satisfied (step S10a, No), step S14a is performed. In step S14a, the memory unit 73 newly memorizes the current value I obtained in step S8a as the past current value Ib. After the process of step S14a is completed, the process returns to step S6a.

Fig. 12 is a timing chart showing the current value I at the time of use of the dryer in the first modification of the first embodiment. In Fig. 12, at each time T0, time T1. . . The current value I in time T14 is called current value I0 and current value I1, respectively. . . Current value I14. Next, the operation when the dryer 1a is used will be described. In addition, the arrangement of the baking machine 1a of the first modification of the first embodiment is the same as that of the baking machine 1 of the first embodiment, and the arrangement is omitted as shown in Fig. 6. In addition, the voltage value V and the air supply amount Q of the baking machine 1a of the first modification of the first embodiment are approximately the same as those of the baking machine 1 of the first embodiment, and therefore, the eighth and ninth aspects are used. The figure is explained.

At time T0, the user generally inserts the blowing portion 22 of the drying machine 1a between the mattress 200 and the quilt 300 as shown in Fig. 6, and operates the operating portion 26 to start the operation of the drying machine 1a (step S1a). ). The operation information acquisition unit 71 acquires the information of the operation (step S2a), the blower control unit 75 operates the blower 3, and the heater control unit 76 operates the heater 4 (step S3a). At time T1, the voltage value V rises to the first set voltage value V1, and the blown air amount Q and the current value I also rise.

The current value acquisition unit 72a acquires the current value I1 measured by the current sensor 5a at time T1 (step S4a). Then, the memory unit 73 re-stores the current value I1 at the time T1 acquired by the current value acquisition unit 72a as the past current value Ib (step S5a).

Then, the timer 77 restarts the measurement of the elapsed time T (step S6a), and when the time T2 is reached (the time T1 arrives after the sampling time TB) When the condition of T≧TB is satisfied, the current value acquisition unit 72a acquires the current value I2 measured by the current sensor 5a at time T2 (step S8a).

Then, the current value determination unit 74a is based on the current value I2 at the time T2 acquired by the current value acquisition unit 72a and the current value I1 at the time T1 stored in the memory unit 73 as the past current value Ib, according to ΔI12=I1. The calculation formula of -I2 calculates the current change amount ΔI12 from time T1 to time T2 (step S9a). According to Fig. 12, the current value I2 at time T2 is higher than the current value I1 at time T1. This is because, when the voltage value V is a fixed value, the current value I supplied to the fan motor 32 changes as the load applied to the blower 3 changes, so that the current value I appears in the first embodiment. The wind pressure value H shown is approximately the same change. Therefore, the current change amount ΔI12 is a negative value, and the threshold current change amount ΔIT is not satisfied. Therefore, the current value determination unit 74a determines that the blow air amount Q is appropriate with respect to the load (step S10a, NO). Then, the memory unit 73 re-stores the current value I2 at the time T2 as the past current value Ib (step S13a), and the timer 77 restarts the measurement of the elapsed time T (step S6a).

When the time T3 is reached (the time after the sampling time TB has elapsed from the time T2), since the condition of T≧TB has been satisfied (YES in step S7a), the current value obtaining unit 72a acquires the current sensor 5a at time T3. The measured current value I3 (step S8a). Then, the current value determination unit 74a is based on the current value I3 at the time T3 acquired by the current value acquisition unit 72a and the current value I2 at the time T2 when the memory unit 73 is stored as the past current value Ib, according to ΔI23=I2. The calculation formula of -I3 calculates the current change amount ΔI23 from time T2 to time T3 (step S9a). As in the first embodiment, during the period from the time T2 to the time T3, the pad 200 and the quilt 300 on the opposite side end portion 15 side form a gap and cause hot air leakage. The hot air leakage causes the load applied to the blower 3 to be greatly reduced. As shown in Fig. 11, the current value I is greatly reduced. Therefore, the current change amount ΔI23 calculated by the current value determining unit 74a is larger than the threshold current change amount ΔIT. Therefore, the current value determining unit 74a determines that the blow air amount Q is excessively large with respect to the load (YES in step S10a), and the blower control unit 75 Control is performed such that the voltage value V supplied to the fan motor 32 is lowered from the first set voltage value V11 to the second set voltage value V12 so that the blow air amount Q of the blower 3 is lowered (step S11a). Therefore, the air supply amount Q at the time point of time T4 is appropriate with respect to the load generated by the quilt 300, and therefore, the gap between the mattress 200 and the quilt 300 disappears without further hot air leakage.

Further, in the first modification of the first embodiment, hot air leakage occurs during the period of time T9 and time T10 because the moisture of the quilt 300 evaporates, but the series of control of steps S6a to S14a is continued. The current value determination unit 74a calculates the current change amount ΔI910 based on the calculation formula of ΔI910=I9-I10, and the current value determination unit 74a determines that the air supply amount Q is relative to the current change amount ΔI910. When the load is too large, the blower control unit 75 lowers the voltage value from the second set voltage value V12 to the third set voltage value V13, so that the gap between the pad 200 and the quilt 300 disappears, and the hot air leakage is stopped.

As described above, in the dryer 1a according to the first modification of the first embodiment, when the current change amount ΔI (the amount of change in the current value I during the sampling time TB) is larger than the predetermined threshold current change amount ΔIT, the blower is lowered. 3 air supply. Therefore, the dryer 1a according to the first modification of the first embodiment can detect the occurrence of hot air leakage based on the current change amount ΔI, and can reduce the amount of air blown by the blower 3 to eliminate the gap causing hot air leakage, and therefore, the embodiment 1 of the drying machine 1 is the same, can It is possible to efficiently dry cotton quilts having different weights or sizes and different loads applied to the air blowing device by one machine.

Second modification of the first embodiment

Fig. 13 is a block diagram showing a baking machine according to a second modification of the first embodiment. First, the configuration of the baking machine 1b according to the second modification of the first embodiment will be described. In the dryer 1b according to the second modification of the first embodiment, the number-of-rotation sensors 5b are provided instead of the wind pressure sensor 5, and the number-of-rotation-acquisition units 72b are provided instead of the wind pressure value acquisition unit 72, and the number of rotations is determined. The portion 74b is substituted for the wind pressure value determining portion 74. In the first modification of the first embodiment, the memory unit 73 at least stores the threshold rotation amount change amount ΔNT (corresponding to the first threshold rotation number change amount ΔNT1 of the present invention) and the past rotation number Nb. The threshold rotation number change amount ΔNT is a positive value set in advance by the manufacturer or the user, and the past rotation number Nb is the number of rotations that the rotation number acquisition unit 72b has acquired in the past.

The rotation number sensor 5b is a sensor that measures the number of rotations N of the fan 31 of the blower 3.

The number-of-rotation acquisition unit 72b is coupled to the number-of-rotation sensors 5b, and obtains the number of rotations N measured by the number-of-rotation sensors 5b. In addition, similarly to the wind pressure value acquisition unit 72, the time point at which the number-of-rotations N is obtained by the number-of-rotations acquisition unit 72b is based on the elapsed time T measured by the timer 77 to be described later.

The number-of-rotations determining unit 74b determines whether or not the amount of blown air Q of the blower 3 is excessive with respect to the load, and the determination is based on the number of rotations N obtained by the number-of-rotations obtaining unit 72b and the amount of change in the number of revolutions ΔNT stored in the memory unit 73 and In the past, the number Nb was rotated. Specifically, the rotation amount change amount ΔN (the difference between the rotation number N and the past rotation number Nb) is calculated according to the calculation formula of ΔN=N-Nb, and the calculated rotation number change amount ΔN and the threshold rotation number are changed. △NT comparison, judge △N≧△NT Whether the conditions are met. The rotation number determining unit 74b determines that the blow air amount Q of the blower 3 is excessively large with respect to the load when the condition is satisfied (ΔN ≧ ΔNT), and determines the air blow amount of the blower 3 when the condition is not satisfied (ΔN < ΔNT). Q is appropriate with respect to load.

Fig. 14 is a flow chart showing the air supply amount control of the dryer in the second modification of the first embodiment. Next, the air supply amount control of the dryer 1b according to the second modification of the first embodiment will be described. In the initial stage of Fig. 11, the dryer 1b is in a stopped state. The processing from step S1b to step S3b is the same as the processing from step S1 to step S3 in the first embodiment, and therefore the description thereof will be omitted.

After the processing of step S3b is completed, step S4b is performed, and the number of rotations obtaining unit 72b obtains the number of rotations N measured by the number-of-rotation sensors 5b in step S4b. After the process of step S4b is completed, step S5b is performed. In step S5b, the memory unit 73 re-stores the number N of rotations acquired in step S4b as the past number of revolutions Nb.

After the process of step S5b is completed, step S6b is performed, and in step S6b, as in step S6 of the first embodiment, the elapsed time T is reset and the measurement of the elapsed time T is restarted. After the processing of step S6b is completed, step S7b is performed. In step S7b, as in step S7 of the first embodiment, the elapsed time T and the sampling time TB are compared to determine whether or not the condition of T≧TB is satisfied. When it is determined in step S7b that the condition is not satisfied (NO in step S7b), the process returns to the determination in step S7b, and when it is determined that the condition is satisfied (YES in step S7b), step S8b is performed.

In step S8b, the number-of-rotations acquiring unit 72b acquires the number N of rotations measured by the number-of-rotation sensors 5b. After the process of step S8b is completed, the process proceeds to step S9b. In step S9b, the amount of change in rotation ΔN is calculated based on the calculation formula of ΔN=N-Nb, which is the number of rotations N and the number of steps acquired by the number-of-rotations acquisition unit 72b. S5b or a difference in the past number of rotations Nb memorized by the storage unit 73 in step S14b to be described later. that is, In step S9b, the number of rotations N obtained by the number-of-rotations acquisition unit 72b is subtracted from the number of rotations N obtained by the number-of-rotations acquisition unit 72b, thereby calculating the amount of change in the number of revolutions during the sampling period TB. N. After the process of step S9b is completed, the process proceeds to step S10b. In step S10b, the number-of-rotations determining unit 74b compares the amount-of-rotation amount ΔN calculated in step S9b with the amount of change in threshold-turn number ΔNT stored in the memory unit 73. It is judged whether or not the condition of ΔN ≧ ΔNT is satisfied.

When the condition of ΔN ≧ ΔNT is satisfied in step S10b (YES in step S10b), step S11b is performed. In step S11b, as in step S11 of the first embodiment, the blower control unit 75 performs control so that the blower is provided. The air supply amount Q of 3 is lowered. After the process of step S11b is completed, step S12b is performed. In step S12b, the blower control unit 75 determines whether or not the amount of air blown by the blower 3 can be further lowered. In step S12a, when the blower control unit 75 determines that the amount of blown air can be further lowered (step S12b, NO), step S13b is performed, and in step S13b, the number-of-rotations acquiring unit 72b obtains the measured rotation of the number-of-rotation sensor 5b. Number N. After the process of step S13b is completed, step S14b is performed. In step S14b, the memory unit 73 newly stores the number of rotations N obtained in step S13b as the past number of rotations Nb. After the process of step S14b is completed, the process returns to step S6b.

When the blower control unit 75 determines that the amount of blown air cannot be reduced again (YES in step S12b), the blower amount control is ended, and the blower 1b continues the operation while the blower amount of the blower 3 is the smallest.

When the condition of ΔN ≧ ΔNT is not satisfied in step S10b (step S10b, NO), step S14b is performed. In step S14b, the storage unit 73 newly stores the number of rotations N obtained in step S8b as the past number of rotations Nb. After the process of step S14b is completed, the process returns to step S6b.

Fig. 15 is a timing chart showing the number of rotations N when the dryer is used in the second modification of the first embodiment. In Figure 15, at each time T0, time T1. . . The number of rotations N of time T14 is referred to as the number of rotations N0 and the number of rotations N1, respectively. . . The number of rotations is N14. Next, the operation when the dryer 1b is used will be described. In addition, the arrangement of the baking machine 1b of the second modification of the first embodiment is the same as that of the baking machine 1 of the first embodiment, and the arrangement is omitted as shown in Fig. 6. In addition, the voltage value V and the air supply amount Q of the baking machine 1b of the second modification of the first embodiment are approximately the same as those of the drying machine 1 of the first embodiment, and therefore, the eighth and ninth aspects are used. The figure is explained.

At time T0, as shown in Fig. 6, the user generally inserts the blowing portion 22 of the drying machine 1b between the mattress 200 and the quilt 300, and operates the operating portion 26 to start the operation of the drying machine 1 (step S1b). ). The operation information acquisition unit 71 acquires the information of the operation (step S2b), the blower control unit 75 operates the blower 3, and the heater control unit 76 operates the heater 4 (step S3b). At time T1, the voltage value V rises to the first set voltage value V1, and the blown air amount Q and the current value I also rise.

The number-of-rotation acquisition unit 72b acquires the number of rotations N measured by the number-of-rotation sensors 5b at time T1 (step S4b). Then, the storage unit 73 re-stores the number of rotations N1 of the time T1 acquired by the rotation number acquisition unit 72b as the past rotation number Nb (step S5b).

Then, the timer 77 restarts the measurement of the elapsed time T (step S6b), and when the time T2 is reached (the time that the time T1 has elapsed after the sampling time TB has elapsed), since the condition of T≧TB is satisfied (step S7b, yes) When the rotation number obtaining unit 72b acquires the time T2, the number of rotations N2 measured by the number sensor 5b is rotated (step S8b).

Then, the number-of-rotations determining unit 74b is based on the number of rotations N2 of the time T2 acquired by the number-of-rotations acquiring unit 72b and the number of rotations N1 at the time T1 stored in the memory unit 73 as the past number of rotations Nb, according to ΔN12=N2- The calculation formula of N1 calculates the amount of change in rotation number ΔN12 from time T1 to time T2 (step S9b). According to Fig. 15, the number of rotations N2 at time T1 and the number of rotations N2 at time T2 are substantially the same. This is because the number N of rotations of the fan 31 is proportional to the amount of blown air Q, and when the amount of blown air Q is a fixed value, the number N of rotations is also a fixed value, so that the number of rotations N is expressed as shown in the first embodiment. The air volume Q is approximately the same change. Therefore, the rotation number change amount ΔN12 is approximately 0, and the threshold rotation amount change amount ΔNT is not satisfied. Therefore, the rotation number determination unit 74b determines that the air supply amount Q is appropriate with respect to the load (step S10b, NO). Then, the storage unit 73 newly stores the number of rotations N2 at the time T2 as the past rotation number Nb (step S13b), and the timer 77 restarts the measurement of the elapsed time T (step S6b).

When the time T3 is reached (the time after the sampling time TB has elapsed from the time T2), since the condition of T≧TB has been satisfied (YES in step S7b), the number-of-rotations acquiring unit 72b acquires the number-of-rotation sensor 5b at time T3. The measured number of rotations N3 (step S8b). Then, the number-of-rotations determining unit 74b calculates the number of rotations N3 at the time T3 acquired by the number-of-rotations acquisition unit 72b and the number of rotations N2 when the memory unit 73 remembers the time T2 of the past number of rotations Nb, according to ΔN23=N3- The calculation formula of N2 calculates the amount of change in rotation ΔN23 from time T2 to time T3 (step S9b). As in the first embodiment, during the period from the time T2 to the time T3, the pad 200 and the quilt 300 on the opposite side end portion 15 side form a gap and cause hot air leakage. The hot air leakage causes the load applied to the blower 3 to be greatly reduced, and as shown in Fig. 11, the number of revolutions rises. Therefore, the number of revolutions calculated by the number-of-rotations determining unit 74b is changed. The amount of change ΔN23 is larger than the threshold rotation number change amount ΔNT, and the number-of-rotations determining unit 74b determines that the blow-up amount Q is excessively large with respect to the load (YES in step S10b), and the blower control unit 75 performs control so that the voltage supplied to the fan motor 32 is controlled. The value V is lowered from the first set voltage value V11 to the second set voltage value V12 so that the blow air amount Q of the blower 3 is lowered (step S11b). Therefore, the air supply amount Q at the time point of time T4 is appropriate with respect to the load generated by the quilt 300, and therefore, the gap between the mattress 200 and the quilt 300 disappears without further hot air leakage.

Further, in the second modification of the first embodiment, hot air leakage occurs during the period of time T9 and time T10 because the moisture of the quilt 300 evaporates. However, since a series of control of steps S6b to S13b is performed, The number-of-rotations determining unit 74b calculates the number-of-rotations amount ΔN910 based on the calculation formula of ΔN910=N10-N9, and the number-of-rotations determining unit 74b determines that the amount of air-turning is ΔN910 because the number-of-turns change amount ΔN910 is larger than the threshold number-of-turns change amount ΔNT. When the Q is excessively large, the blower control unit 75 lowers the voltage value from the second set voltage value V12 to the third set voltage value V13, so that the gap between the pad 200 and the quilt 300 disappears, and the hot air leakage is stopped.

As described above, in the baking machine 1b according to the second modification of the first embodiment, when the amount of change in rotation ΔN (the amount of increase in the period of the sampling time TB of the number of rotations N) is larger than the predetermined amount of change in the threshold number of revolutions ΔNT, the amount is decreased. The amount of air blown by the blower 3. Therefore, the dryer 1b according to the first modification of the first embodiment can detect the occurrence of hot air leakage based on the amount of change in rotation ΔN, and can reduce the amount of air blown by the blower 3 to eliminate the gap causing hot air leakage, and therefore, In the same manner as the dryer 1 of the first aspect, it is possible to efficiently dry the quilts having different weights or sizes and different loads applied to the air blowing device by one machine.

Embodiment 2

Next, the second embodiment will be described. In the control of the drying machine 1 of the first embodiment, the wind pressure change amount ΔH (the amount of change in the period of the sampling time TB) is calculated, and the occurrence of the hot air leak is detected based on the wind pressure change amount ΔH. In the control of the drying machine 1c of 2, the control for detecting the occurrence of the hot air leakage without calculating the wind pressure change amount ΔH is performed. In addition, the drying machine 1c of the second embodiment has the contents of the determination by the threshold wind pressure value determining unit 78 and the wind pressure value determining unit 74, the content of the control by the dryer 1c, and the contents of the memory unit 73. The rest of the configuration is substantially the same as that of the dryer 1 of the first embodiment, and therefore the description of the same portions will be omitted.

Fig. 16 is a block diagram of the baking machine of the second embodiment. Fig. 17 is a table showing the relationship between the voltage value of the dryer and the lower limit wind pressure value in the second embodiment. First, the configuration of the baking machine 1c of the second embodiment will be described. In addition to the configuration of the drying machine 1 of the first embodiment, the control unit 7 of the drying machine 1c of the second embodiment includes a threshold wind pressure value determining unit 78 as a threshold determining means.

The threshold wind pressure value determining unit 78 acquires the voltage value V supplied from the blower control unit 75 to the fan motor 32, and determines the lower limit wind pressure value Hd based on the acquired voltage value V. Specifically, as shown in FIG. 17, the threshold wind pressure value determining unit 78 determines a corresponding lower limit wind pressure value for each set voltage in addition to the minimum set voltage value, and in the case of the second embodiment, The lower limit wind pressure value Hd when the voltage value V is the first set voltage value V11 is determined as the first lower limit wind pressure value Hd1, and the lower limit wind pressure value Hd when the voltage value V is the second set voltage value V12 is determined as the second lower limit wind. The pressure value is Hd2.

The lower limit wind pressure value Hd determined by the threshold wind pressure value determining unit 78 is stored in the memory unit 73. In the second embodiment, the memory unit 73 memorizes the first The lower limit wind pressure value Hd1 and the second lower limit wind pressure value Hd2. In addition, in the second embodiment, each of the first lower limit wind pressure value Hd1 and the second lower limit wind pressure value Hd2 is set in advance to satisfy Hd1, as the set voltage corresponding to each lower limit wind pressure value Hd is larger. >Hd2 relationship.

In addition, the wind pressure value determining unit 74 determines the air blowing amount Q of the air blower 3 with respect to the load based on the wind pressure value H obtained by the wind pressure value obtaining unit 72 and the lower limit wind pressure value Hd determined by the threshold wind pressure value determining unit 78. Is it too big? Specifically, the wind pressure value H and the lower limit wind pressure value Hd are compared to determine whether H < Hd is satisfied. When the condition is satisfied (H<Hd), the wind pressure value determining unit 74 determines that the air blowing amount Q of the air blower 3 is excessively large with respect to the load, and determines that the air blowing amount Q of the air blower 3 is relative to the load when the condition is not satisfied (H≧Hd). The load is appropriate.

Fig. 18 is a flow chart showing the air supply amount control of the drying machine of the second embodiment. Next, the control of the baking machine 1c of the second embodiment will be described. In the initial stage of Fig. 18, the dryer 1c is in a stopped state. The processing from step S1c to step S3c is the same as the processing from step S1 to step S3 in the first embodiment, and therefore the description thereof will be omitted.

After the processing of step S3c is completed, step S4c is performed, and in step S4c, as in step S6 of the first embodiment, the elapsed time T is reset and the measurement of the elapsed time T is restarted. After the processing of step S4c is completed, step S5c is performed, and in step S5c, as in step S7 of the first embodiment, the elapsed time T and the sampling time TB are compared to determine whether or not the condition of T≧TB is satisfied. If it is determined in step S5c that the condition is not satisfied (NO in step S5c), the process returns to the determination in step S5c, and when it is determined that the condition is satisfied (YES in step S5c), step S6c is performed.

In step S6c, the threshold wind pressure value determining unit 78 acquires the blower control The portion 75 is supplied with a voltage value V to the fan motor 32. After the process of step S6c is completed, the process proceeds to step S7c. In step S7c, the threshold wind pressure value determining unit 78 determines the lower limit wind pressure value Hd based on the voltage value V obtained in step S6c. Specifically, in the second embodiment, when the first set voltage value V11 is set, the lower limit wind pressure value Hd is determined as the first lower limit wind pressure value Hd1, and when the second set voltage value V12 is set, the lower limit wind pressure value Hd is set. It is determined as the second lower limit wind pressure value Hd2.

After the process of step S7c is completed, the process proceeds to step S8c. In step S8c, the wind pressure value acquisition unit 72 acquires the wind pressure value H measured by the wind pressure sensor 5. After the process of step S8c is completed, the process proceeds to step S9c. In step S9c, the wind pressure value determination unit 74 compares the wind pressure value H obtained in step S8c with the lower limit wind pressure value Hd determined in step S7c, and determines whether H<Hd is satisfied. The condition is to determine whether the blow amount Q of the blower 3 is excessive with respect to the load.

When the condition of H < Hd is satisfied in step S9c (step S9c, YES), that is, when the blow-up amount Q of the blower 3 is excessively large with respect to the load, step S10c is performed. In step S10c, the blower control unit 75 performs control so that the blow air amount Q of the blower 3 is lowered. Specifically, when the current voltage value V is the first set voltage value V11, the blower control unit 75 lowers the voltage value V after the control to the second set voltage value V12 and the like, and lowers the voltage supplied to the fan motor 32. Value V. After the process of step S10c is completed, step S11c is performed. In step S11c, the blower control unit 75 determines whether or not the amount of air blown by the blower 3 can be further lowered. Specifically, when the current voltage value is set to the minimum third set voltage value V13 among the set voltage values, the blower control unit 75 can no longer reduce the voltage value V supplied to the fan motor 32. It is judged that the amount of air supply cannot be reduced. In step S11c, when sending When the fan control unit 75 determines that the amount of blown air can be further reduced (step S11c, NO), the process returns to step S4c, and the timer 77 resets the elapsed time T again and restarts the measurement of the elapsed time T.

When the blower control unit 75 determines that the amount of blown air cannot be reduced again (YES in step S11c), the blower amount control is ended, and the blower 1c continues the operation while the blower amount of the blower 3 is the smallest.

When the condition of H < Hd is not satisfied in step S9c (step S9c, NO), that is, when the blow-up amount Q of the blower 3 is appropriate with respect to the load, the process returns to step S4c, and the timer 77 resets the elapsed time T again. And the measurement of the elapsed time T is restarted.

Fig. 19 is a timing chart showing the wind pressure value H at the time of use of the dryer of the second embodiment. Next, the operation of the baking machine 1c of the second embodiment at the time of use will be described. In addition, the arrangement of the drying machine 1c of the second embodiment is the same as that of the baking machine 1 of the first embodiment, and the voltage value V and the air blowing amount Q are as described later, and the drying machine of the first embodiment is used. 1 is approximately the same figure, and therefore will be described using Figs. 8 and 9.

At time T0, as shown in Fig. 6, the user generally inserts the blowing portion 22 of the drying machine 1c between the mattress 200 and the quilt 300, and operates the operating portion 26 to start the operation of the drying machine 1 (step S1c). ). The operation information acquisition unit 71 acquires the information of the operation (step S2c), the blower control unit 75 operates the blower 3, and the heater control unit 76 operates the heater 4 (step S3c). At time T1, the voltage value V rises to the first set voltage value V1, and the blown air amount Q and the current value I also rise.

Then, the timer 77 restarts the measurement of the elapsed time T (step S4c), and when the time T2 is reached (the time T1 arrives after the sampling time TB arrives) When the condition of T ≧ TB is satisfied (YES in step S5c), the threshold wind pressure value determining unit 78 acquires the voltage value V supplied from the blower control unit 75 to the fan motor 32 (step S6c). Since the voltage value V at the time T2 is the first set voltage value V11, the lower limit wind pressure value Hd is determined as the first lower limit wind pressure value Hd1 (step S7c).

Then, the wind pressure value acquisition unit 72 acquires the wind pressure value H3 measured by the wind pressure sensor 5 at time T3 (step S8c). The wind pressure value H3 at the time T3 is greatly lowered due to the relationship of the hot air leakage, and is lower than the first lower limit wind pressure value Hd1. Therefore, the wind pressure value determining unit 74 determines that the blow air amount Q is excessively large with respect to the load (YES in step S9c), and the blower control unit 75 controls so that the voltage value V supplied to the fan motor 32 falls from the first set voltage value V11. The second set voltage value V12 is set such that the blow air amount Q of the blower 3 is lowered (step S10c). Therefore, the air supply amount Q at the time point of time T4 is appropriate with respect to the load generated by the quilt 300, and therefore, the gap between the mattress 200 and the quilt 300 disappears without further hot air leakage.

Since the voltage value V after the time T4 has been changed to the second set voltage value V12, the threshold wind pressure value determining unit 78 determines the lower limit wind pressure value Hd as the second lower limit wind pressure value Hd2 during the period from the time T4 to the time T9. (Step S7c), since each of the wind pressure values H4 to H9 is larger than the second lower limit wind pressure value Hd2, the wind pressure value determining unit 74 determines that the air blowing amount Q is appropriate (NO in step S9c), and maintains the air blowing amount Q at the fixed value. value. However, during the period of time T9 and time T10, hot air leaks due to evaporation of moisture of the quilt 300, and the wind pressure value H10 is lower than the second lower limit wind pressure value Hd2 at time T10. Therefore, the wind pressure value determining unit 74 determines that the blow amount Q is excessively large with respect to the load (YES in step S9c), and the blower control unit 75 controls to lower the voltage value V supplied to the fan motor 32 from the second set voltage value V12 to The third set voltage value V13 causes the blow amount Q of the blower 3 to be further lowered (step S10c), so that the gap generated between the pad 200 and the quilt 300 disappears again and the hot air leakage is stopped.

As described above, in the baking machine 1c of the second embodiment, the lower limit wind pressure value Hd is set in accordance with the value of the voltage value V, and when the wind pressure value H is lower than the lower limit wind pressure value Hd, the air blowing amount of the blower 3 is lowered. Therefore, the dryer 1c of the second embodiment can detect the occurrence of hot air leakage based on the wind pressure value H and the voltage value V, and reduce the amount of air blown by the blower 3 so that the gap of the hot air leak disappears. Like the drying machine 1, it is possible to efficiently dry the quilts having different weights or sizes and different loads applied to the air blowing device by one machine.

Further, in the dryer 1c of the second embodiment, the set voltage value controllable by the blower control unit 75 includes three stages of the first to third set voltage values, and the lower limit wind pressure values correspond to the first set voltage value and The second set voltage value is not limited thereto, and the set voltage value is not limited to three stages, and the corresponding lower limit wind pressure value is set in advance for each set voltage except for the minimum set voltage value. can.

In the drying machine 1c of the second embodiment, the air blowing amount of the blower 3 is reduced in accordance with the wind pressure value H. However, the present invention is not limited thereto, and the first modification and the second embodiment of the following second embodiment may be employed. In the second modification, the amount of air blown by the blower 3 is lowered in accordance with the current value I and the number of revolutions N.

First modification of the second embodiment

Fig. 20 is a block diagram showing a baking machine according to a first modification of the second embodiment. Fig. 21 is a table showing the relationship between the voltage value of the dryer and the lower limit current value in the first modification of the second embodiment. The baking machine 1d according to the first modification of the second embodiment In contrast to the dryer 1c of the second embodiment, the current sensor 5a is provided in place of the wind pressure sensor 5, and has a current value acquisition unit 72a instead of the wind pressure value acquisition unit 72, and has a current value determination unit 74a. The wind pressure value determining unit 74 includes a threshold current value determining unit 78a instead of the threshold wind pressure value determining unit 78 as a threshold determining means.

In addition to the minimum set voltage value, the threshold current value determination unit 78a of the dryer 1d according to the first modification of the second embodiment determines the corresponding lower limit current value for each set voltage. In the case of the first modification, when the voltage value V is the first set voltage value V11, the lower limit current value Id is determined as the first lower limit current value Id1, and when the voltage value V is the second set voltage value V12, the lower limit wind pressure is applied. The value Hd is determined as the second lower limit current value Id2.

The lower limit current value Id determined by the threshold current value determining unit 78a is stored in the memory unit 73. In the first modified example of the second embodiment, the first lower limit current value Id1 and the second lower limit current value Id2 are stored. Further, the larger the set voltage corresponding to each lower limit current value Id is, the larger the value is, and the respective values are set in advance to satisfy the relationship of Id1>Id2.

In addition, the current value determination unit 74a determines whether or not the air supply amount Q of the air blower 3 is excessively large with respect to the load, based on the current value I obtained by the current value acquisition unit 72a and the lower limit current value Id determined by the threshold current value determination unit 78a. Specifically, the current value I and the lower limit current value Id are compared to determine whether I<Id is satisfied, and when the condition is satisfied (I<Id), it is determined that the air supply amount Q of the blower 3 is excessive with respect to the load, and when the condition is not satisfied ( I ≧ Id), it is judged that the blow air amount Q of the blower 3 is appropriate with respect to the load.

Fig. 22 is a flow chart showing the air supply amount control of the dryer in the first modification of the second embodiment. Next, the baking of the first modification of the second embodiment will be described. Controlled by machine 1d. In the initial stage of Fig. 22, the dryer 1d is in a stopped state. The processing from step S1d to step S6d is the same as the processing from step S1c to step S6c in the second embodiment, and therefore the description thereof will be omitted.

After the voltage value V is obtained in step S6d, step S7d is performed. In step S7d, the threshold current value determining unit 78a determines the lower limit current value Id based on the voltage value V obtained in step S6d. Specifically, in the first modification of the second embodiment, the lower limit current value Id is determined as the first lower limit current value Id1 when the first set voltage value V11 is set, and the lower limit current is set when the second set voltage value is V12. The value Id is determined as the second lower limit current value Id2.

After the process of step S7d is completed, step S8d is performed. In step S8d, the current value acquisition unit 72a acquires the current value I measured by the current sensor 5a. After the process of step S8d is completed, the process proceeds to step S9d. In step S9d, the current value determination unit 74a compares the current value I obtained in step S8d with the lower limit current value Id determined in step S7d, and determines whether or not the condition of I<Id is satisfied. In order to determine whether the blow amount Q of the blower 3 is excessive with respect to the load.

In the case where the condition of I<Id is satisfied in step S9d (YES in step S9d), that is, when the blow-up amount Q of the blower 3 is excessively large with respect to the load, step S10d is performed. In step S10d, similarly to step S10c of the second embodiment, the blower control unit 75 performs control so that the blow air amount Q of the blower 3 is lowered. After the process of step S10d is completed, step S11d is performed. Similarly to step S11c of the second embodiment, the blower control unit 75 determines in step S11d whether or not the blower amount of the blower 3 can be further lowered. In step S11d, when the blower control unit 75 determines that the amount of blown air can be further reduced (NO in step S11d), the flow returns to step S4d.

In step S11d, the blower control unit 75 determines the amount of air blown. When it is not possible to reduce it again (YES in step S11d), the air supply amount control is ended, and the dryer 1 continues to operate in a state where the blower amount of the blower 3 is the smallest.

When the condition of I<Id is not satisfied in step S9d (step S9d, NO), that is, if the blower amount Q of the blower 3 is appropriate with respect to the load, the process returns to step S4d.

In the dryer 1d according to the first modification of the second embodiment, the lower limit current value Id is set based on the value of the voltage value V, and when the current value I is lower than the lower limit current value Id, the blower amount of the blower 3 is lowered. Therefore, the dryer 1d according to the first modification of the second embodiment can detect the occurrence of hot air leakage based on the current value I and the voltage value V, and reduce the amount of air blown by the blower 3 so that the gap of the hot air leak disappears. In the same manner as the dryer 1 of the first aspect, it is possible to efficiently dry the quilts having different weights or sizes and different loads applied to the air blowing device by one machine.

Second modification of the second embodiment

Figure 23 is a block diagram of a baking machine according to a second modification of the second embodiment. Fig. 24 is a table showing the relationship between the voltage value of the dryer and the number of upper limit rotations in the second modification of the second embodiment. The dryer 1e according to the second modification of the second embodiment has a rotation number sensor 5b instead of the wind pressure sensor 5 as compared with the dryer 1c of the second embodiment, and has a rotation number acquisition unit 72b. The wind pressure value acquisition unit 72 includes a rotation number determination unit 74b instead of the wind pressure value determination unit 74, and has a threshold rotation number determination unit 78b instead of the threshold wind pressure value determination unit 78 as a threshold value determination unit.

In addition to the minimum set voltage value, the threshold rotation number determination unit 78b of the dryer 1e according to the second modification of the second embodiment determines the corresponding upper limit rotation number for each set voltage, and the second embodiment of the second embodiment In the case of the modification, the upper limit rotation number Nu when the voltage value V is the first set voltage value V11 When the first upper limit rotation number Nu1 is determined and the voltage value V is the second set voltage value V12, the upper limit rotation number Nu is determined as the second upper limit rotation number Nu2.

In the memory unit 73, the upper limit rotation number Nu determined by the threshold rotation number determining unit 78b is stored. In the second modification of the second embodiment, the first upper limit rotation number Nu1 and the second upper limit rotation number Nu2 are stored. Further, the larger the set voltage corresponding to the value of each of the upper limit rotation numbers Nu is, the larger the value is, and the respective values are set in advance to satisfy the relationship of Nu1>Nu2.

In addition, the number-of-rotations determining unit 74b determines whether or not the blow-up amount Q of the blower 3 is excessively large with respect to the load, based on the number of rotations N acquired by the number-of-rotations obtaining unit 72b and the number of upper-order rotations Nu determined by the threshold number-of-turns determining unit 78b. Specifically, the number of rotations N and the number of rotations of the upper limit are compared to determine whether N>Nu is satisfied. When the condition is satisfied (N>Nu), it is determined that the amount of blown air Q of the blower 3 is excessive with respect to the load, and when the condition is not satisfied ( N≦Nu), it is judged that the blow amount Q of the blower 3 is appropriate with respect to the load.

Fig. 25 is a flow chart showing the air supply amount control of the dryer in the second modification of the second embodiment. Next, the control of the baking machine 1e of the second modification of the second embodiment will be described. In the initial stage of Fig. 25, the dryer 1e is in a stopped state. The processing from step S1e to step S6e is the same as the processing from step S1c to step S6c in the second embodiment, and therefore the description thereof will be omitted.

After the voltage value V is obtained in step S6e, step S7e is performed. In step S7e, the threshold rotation number determining unit 78b determines the upper limit rotation number Nu based on the voltage value V obtained in step S6e. Specifically, in the second modification of the second embodiment, when the first set voltage value V11 is set, the upper limit rotation number Nu is determined as the first upper limit rotation number Nu1, and when the second set voltage value V12 is set, the upper limit is applied. The number of rotations Nu is determined as the second upper limit rotation number Nu2.

After the process of step S7e is completed, the process proceeds to step S8e. In step S8e, the number-of-rotations acquiring unit 72b acquires the number of rotations N measured by the number-of-rotation sensors 5b. After the process of step S8e is completed, the process proceeds to step S9e. In step S9e, the number-of-rotations determining unit 74b compares the number of rotations N obtained in step S8e with the number of upper-order rotations Nu determined in step S7e, and determines whether N>Nu is satisfied. It is judged whether or not the blow air amount Q of the blower 3 is excessive with respect to the load.

When the condition of N>Nu is satisfied in step S9e (step S9e, YES), that is, when the blow-up amount Q of the blower 3 is excessively large with respect to the load, step S10e is performed. In step S10e, similarly to step S10c of the second embodiment, the blower control unit 75 performs control so that the blow air amount Q of the blower 3 is lowered. After the process of step S10e is completed, step S11e is performed. Similarly to step S11c of the second embodiment, the blower control unit 75 determines in step S11e whether or not the blower amount of the blower 3 can be further lowered. In step S11e, when the blower control unit 75 determines that the amount of blown air can be further reduced (NO in step S11e), the flow returns to step S4e.

When the blower control unit 75 determines that the amount of blown air cannot be reduced again (YES in step S11e), the blower amount control is ended, and the blower 1e continues the operation while the blower amount of the blower 3 is the smallest.

When the condition of N>Nu is not satisfied in step S9e (step S9e, NO), that is, when the blow-up amount Q of the blower 3 is appropriate with respect to the load, the process returns to step S4e.

In the dryer 1e according to the second modification of the second embodiment, the upper limit rotation number Nu is set based on the value of the voltage value V, and when the number of rotations N is higher than the upper limit rotation number Nu, the amount of air blown by the blower 3 is reduced. Therefore, in the second modification of the second embodiment The drying machine 1e detects the occurrence of hot air leakage based on the number of rotations N and the voltage value V, and reduces the amount of air blown by the blower 3 so that the gap of the hot air leaks disappears. Therefore, like the dryer 1 of the first embodiment, it is possible to use 1 The machine can efficiently dry quilts of different weights or sizes and different loads applied to the air blowing device.

Embodiment 3

Next, the third embodiment will be described. In the control of the drying machine 1f of the third embodiment, in addition to the control of the drying machine 1 of the first embodiment, when the air blowing amount Q of the air blower 3 is too small with respect to the load, the air blowing amount Q of the air blower 3 is executed. Increased control. In addition, in the third embodiment, the configuration of the wind pressure value determining unit 74, the memory content of the memory unit 73, and the flow rate control flowchart are substantially the same as those of the baking machine 1 of the first embodiment. Therefore, the description of the same portions is omitted.

The memory unit 73 at least stores the first threshold wind pressure change amount ΔHT1, the second threshold wind pressure change amount ΔHT2, and the past wind pressure value Hb. The first threshold wind pressure change amount ΔHT1 is the same as the threshold wind pressure change amount ΔHT of the first embodiment, and is used when the wind pressure value determination unit 74 to be described later determines whether or not the blow air amount Q of the blower 3 is excessively large. The positive value of the preset. The second threshold wind pressure change amount ΔHT2 is a preset negative value used by the wind pressure value determining unit 74 to be described later to determine whether or not the blow air amount Q of the blower 3 is too small with respect to the load.

In addition, the wind pressure value determination unit 74 is based on the wind pressure value H obtained by the wind pressure value acquisition unit 72 and the first threshold wind pressure change amount Δ stored in the memory unit 73, similarly to the wind pressure value determination unit 74 of the first embodiment. The HT1 and the past wind pressure value Hb determine whether or not the blow air amount Q of the blower 3 is excessive with respect to the load.

The second threshold wind pressure change amount ΔHT2 and the past wind pressure value Hb determine whether or not the blow air amount Q of the blower 3 is too small with respect to the load. Specifically, the wind pressure value determining unit 74 calculates the wind pressure change amount ΔH based on the calculation formula of ΔH=Hb-H, and compares the calculated wind pressure change amount ΔH with the second threshold wind pressure change amount ΔHT2. It is judged whether or not the condition of ΔH≦ΔHT2 is satisfied. When the condition is satisfied (ΔH≦ΔHT2), the wind pressure value determining unit 74 determines that the blow air amount Q of the blower 3 is too small with respect to the load, and determines that the blower 3 is sent when the condition is not satisfied (ΔH>ΔHT2).

When the condition of ΔH ≦ Δ HT2 is satisfied in step S18 (YES in step S18), that is, when the blow-up amount Q of the blower 3 is too small with respect to the load, step S19 is performed. In step S19, the blower control unit 75 performs control so that the blow air amount Q of the blower 3 is increased. Specifically, when the current voltage value V is the second set voltage value V12, the blower control unit 75 increases the voltage supplied to the fan motor 32 by changing the voltage value V after the control to the first set voltage value V11 or the like.
