Description

  The present invention relates to a washing / drying machine that removes dirt and odor components using mist during washing and drying.

  In the conventional mist device, the amount of atomization generated varies greatly depending on the stability of the power supply voltage supplied to the high-voltage oscillation circuit that vibrates the ultrasonic vibrator and the variations in the parts used in the high-voltage oscillation circuit. . In particular, the transistor in the high voltage oscillation circuit has a wide variation range of the current amplification factor (hfe) (for example, there is a variation of about twice as high as hfe: 90 to 180), which affects the amount of atomization. Further, the power supply voltage supplied to the high-voltage oscillation circuit has a variation of 5% to 10% due to the accuracy of the semiconductor element used inside even if it is a DC stabilized power supply. Therefore, in order to generate the required amount of atomization, parts are selected and high-precision parts are used.

  For example, in order to detect and adjust the atomization amount, the current flowing through the ultrasonic vibrator of the high voltage generation circuit of the atomization generation circuit is measured by providing a highly insulating current measurement circuit, and the high voltage generation circuit is measured from the atomization amount. There is a refrigerator equipped with an atomization device that controls the voltage applied to the ultrasonic vibrator from the head. (For example, refer to Patent Document 1).

  In FIG. 6, the ultrasonic atomizer 115 includes a piezoelectric element 122, a high voltage / oscillation circuit 135 for applying a high frequency to the piezoelectric element 122, a current detection circuit 136 for detecting a current, and an ultrasonic atomizer 115. A control circuit 137 for controlling the flow rate, and an atomization determination means 138 for determining the amount of water in the atomization unit 115 from the current value detected by the current detection circuit 136 in the control circuit 137.

  The operation will be described below.

  In the ultrasonic atomizer 115, the voltage oscillated from the high voltage / oscillator circuit 135 is applied to the piezoelectric vibrator 122. The current detection circuit 136 detects the current value at the time of application as a signal S1, inputs the signal as a signal S2 to the atomizer control circuit 137 as a control means, and the atomization determination means 138 indicates the atomization status. The output voltage of the high-voltage / oscillation circuit 135 is adjusted.

  By this method, the atomization amount can be obtained from the current flowing through the piezoelectric vibrator, and the atomization amount can be adjusted by the control means.

  However, in the mist device described above, it is necessary to provide a highly insulating current measurement circuit in order to measure the current of the high voltage generation circuit, and thus the device is expensive and highly safe. In addition, since components such as high-voltage generation circuits and piezoelectric elements have performance variations, complicated control is required in which the atomizing device control circuit controls the detected current to generate the atomization amount with high accuracy. .

  The present invention solves the above-mentioned conventional problem, and by changing the voltage at a constant rate by the switching means of the reference power supply unit of the power supply unit to a simple mist device, it is within the required atomization amount range in advance.

By calculating the amount of atomization, it can be compared with the required atomization amount range of the setting unit to determine whether the amount of atomization is insufficient, and from the determination result, the voltage adjustment of the power supply unit by the adjustment means Can be corrected at the next and subsequent occurrences of mist from the constant gradient value between the applied voltage and the atomization amount of the mist device set in the setting unit to the required atomization amount.

  In addition, by adjusting the voltage of the power supply unit, which is the voltage applied to the oscillation circuit, the variation in atomization amount due to the variation in the current amplification factor (hfe) of the transistor in the original oscillation circuit depends on the current amplification factor (hfe) of the transistor. Correct the effect. As for the correction, since the voltage of the power supply unit also varies, the power supply unit reference voltage can be changed by a simple switching device so that it falls within the range of atomization amount per unit time required for the washing and drying machine. The necessary atomization amount can be secured by performing.

  As explained above, according to the present invention, the first water level detecting means for securing the water amount of the water tank of the mist device and the second water level detecting means for preventing failure of the mist device due to insufficient water amount are utilized. , By measuring the amount of water from the known first water level detection means to the second water level detection means with the timer means, and calculating the atomization amount of the mist device with the calculation means, new parts and high insulation No parts are required, and the amount of atomization can be obtained easily and inexpensively.

  In addition, strict adjustments can be made for each washing and drying machine by setting the atomization amount range (width) required for each washing and drying machine and the constant gradient value of the applied voltage and atomization amount of the mist device in the setting section. It is not necessary, it can be adjusted to the required atomization amount automatically in the next and subsequent operations by adjusting the voltage at a certain ratio, and the effect of component variations can be easily adjusted at low cost. .

(Embodiment 1)
FIG. 1 shows a configuration diagram of a washing / drying machine according to Embodiment 1 of the present invention.

  In FIG. 1, a washing / drying machine 6 includes a washing / drying unit 5 for performing washing / drying, a washing / drying control unit 1 for controlling washing / drying and a mist function, a power supply unit 2 for supplying power to the mist function, and generation of atomization. Water tank 4 for storing water for water, first water level detection means 42 for detecting the upper limit water level 40 of the water level in the water tank 4, and a lower limit water level for preventing failure of the atomization generator 31 which is an ultrasonic vibrator The second water level detecting means 43 for detecting 41 and the mist device 3 which is an oscillation circuit for causing the atomization generating unit 31 to vibrate ultrasonically.

  The washing / drying control unit 1 includes, in the washing / drying control unit 1 that controls the washing / drying function unit 5, an activation detection unit 14 that detects the start of operation of the mist device 3, a timer unit 11 that times the mist operation time, The setting unit 13 for setting the range of the atomization amount value required by the washing / drying machine 6, the time of the timer means 11, and the detection signals of the first water level detection means 42 and the second water level detection means 43 of the mist device 3. The calculation means 12 which calculates the atomization amount per unit time by operation | movement is comprised.

  The power supply unit 2 includes a voltage stabilization yesterday 21 in which the supply voltage to the mist device 3 is a stable DC voltage, and an adjustment unit 22 that adjusts the voltage value of the DC voltage at a constant rate. The adjusting means 22 includes a reference voltage unit 221 serving as a reference voltage of a DC voltage, and a switching unit 222 that changes the voltage of the reference voltage unit 221 by a certain ratio. The switching unit 222 sets and records the switching conditions. The switching setting unit 223 is configured.

  FIG. 2 shows a case where the power source unit 2 is a DC power source using a switching power source. A voltage stabilizing function 21 for inputting a commercial power source includes a smoothing unit 213 and a switching circuit for switching the smoothed voltage. 211, and a transformer 212 that converts the voltage into a mist supply voltage. The adjustment unit 22 sets and records a reference voltage unit 221, a switching unit 222 that switches the reference voltage by resistance voltage division, and a switching condition thereof. It comprises a switching setting unit 223 and a feedback circuit 224 that adjusts the voltage according to the switching condition.

  The switching unit 222 is composed of a -10% voltage switching SWA, a -5% voltage switching SWB, a + 5% voltage switching SWC, and a + 10% voltage switching SWD that adjust the voltage at a certain ratio by changing the resistance value. ing.

  3A is a voltage waveform of the smoothing unit output Z1 which is a voltage immediately after smoothing of the voltage stabilization function 21 after the commercial power supply input in FIG. 2, and FIG. 3B is a stable waveform with little ripple. It is a voltage waveform of DC voltage output Z2 which is a converted DC voltage output point.

  FIG. 4 is a diagram showing the amount of atomization per unit time in the mist function with respect to the voltage change of the power supply unit 2.

  The power supply unit 2 outputs an error voltage having a voltage of about 5 to 10% due to component variations. Therefore, when the voltage changes, even if the mist device 3 is the same, the amount of atomization varies, and the straight line of the upper limit value H1 or H2 indicates. Further, for example, the change in the atomization amount due to the variation in the current amplification factor (hfe) of the oscillation circuit component transistor of the mist device 3 is shown in the range from the upper limit value H1 to the lower limit value H2.

  The required atomization amount of the washing / drying machine 6 indicates that the atomization amount should be within the range lower limit J2 to the range upper limit J1.

  For example, the atomization amount point K1 when the mist device 3 is operated with the voltage before the adjustment unit 22 performs voltage adjustment in the transistor lower limit product, and the atomization amount when the voltage adjustment of the adjustment unit 22 is + 10% This is shown as point K2. Moreover, it is set as the atomization amount point K3 when the mist device 3 is operated with the voltage before the adjustment unit 22 performs voltage adjustment in the transistor upper limit product, and atomization when the voltage adjustment of the adjustment unit 22 is −5%. It is shown as a quantity point K4.

  In FIG. 5, the switching setting unit 223 in FIG. 1 periodically calculates the atomization amount by the calculation means 12 at regular intervals, confirms whether it is the required atomization amount, and performs switching setting as necessary. 223B.

  Next, the operation and action of the washing / drying machine 6 having such a configuration will be described.

  Here, it is assumed that the atomization amount range per unit time required for the washing and drying machine 6 is set in the setting unit 13 as 10 to 14 ml / min, and the components of the oscillation circuit of the mist device 3 are the variation lower limit products. When the voltage of the power supply unit 2 has an error of −5% before the adjustment, when the voltage is adjusted by + 10%, the water amount at the time of the water level of the first water level detection means 42 of the water tank 4 is 200 ml, and the second water level detection means 43 An example in which the water amount at the time of the water level is 150 ml is shown.

  First, when the washing impression machine 6 uses the mist function for the first time, the power supply unit 2 is in an unknown state as to which value of the error of 5 to 10% is in the initial power supply voltage due to component variations. In this state, the mist function starts to operate.

  At the start of the mist function, first, water is supplied to the water tank 4, and the water level is detected by the first water level detection means 42 to notify the washing / drying control unit 1 and the water level 40 of 200 ml is calculated by the calculation means 12. Is detected. The power supply unit 2 supplies the voltage to the mist device 3 with the voltage of the adjusting unit 22 in the initial state, and the mist device 3 starts to operate. The activation detection means 14 detects the start of the operation, and the time measurement of the timer means 11 starts.

  Next, the mist device 3 applies a signal oscillated by the transistor of the internal component variation lower limit product to the atomization generating unit 31 to atomize the water in the water storage tank, and supplies it as a mist to the washing and drying function unit. The state is continued, the water level in the water tank 4 drops to the lower limit water level 41 of 150 ml, the second water level detection means 43 detects and notifies the washing / drying control unit 1 to stop the operation of the mist device 3 and calculate at the same time. The time measurement value of the timer means 11 is counted by the means 12. For example, when the measurement value is 6 minutes 15 seconds, the atomization amount per unit time is 8 ml / min from the water reduction amount 50 ml (200-150 = 50 ml) by the mist function. (K1 point in FIG. 4) is calculated.

  Next, the calculated value 8 ml / min in the calculating means 12 is compared with the required atomization amount range 10 to 14 ml / min set in the setting unit 13, and the atomization amount is increased because it is insufficient. Therefore, the washing / drying control unit 1 instructs the switching unit 222 of the power supply unit 2 to increase the voltage, and the switching setting unit 223 sets a certain ratio of + 10% in order to switch the voltage of the reference voltage unit 221 (FIG. 2). SWD) is switched and the value is recorded, and the voltage value of the voltage stabilization function 21 is increased by 10%. In this case, since the constant gradient of the atomization amount in the voltage change applied to the mist device 3 is set in the setting unit 13, a constant ratio value to be switched by the switching unit 222 can be predicted. A constant switching value can be set.

  Furthermore, when the next mist function is operated, the mist device 3 starts operating at the voltage value of the power supply unit 2 of + 10% which is the value of the switching setting unit 223, and the atomization amount is calculated in the same manner as the previous time. The means 12 calculates the atomization amount per unit time as 11 ml / min (point K2 in FIG. 4) from the time measured by the timer means 11 of 4 minutes and 32 seconds and the reduced water amount of 50 ml. As a result, the atomization amount falls within the required atomization amount range, and therefore the mist function necessary for the washing / drying machine 6 is satisfied.

  By performing such an operation, the performance of the mist function in the initial state is grasped by the first operation, and automatically adjusted so as to satisfy the mist performance as the washing / drying machine 6 in the subsequent operation.

  For example, in the case of the upper limit variation transistor of the internal components of the mist device 3, even when the atomization amount in the initial state becomes the K3 point (for example, 14.5 ml / min) in FIG. By switching the switching setting unit 223 to −5% so as to be within the amount range (necessary atomization amount range upper limit value J1 to necessary atomization amount range lower limit value J2 in FIG. 4), point K4 in FIG. Min) of atomization amount. In the case of an intermediate product with variation, there may be a value in the required atomization amount range from the initial state, but in that case, the state is continued.

  Further, by setting the switching setting unit 223 as the regular switching unit 223B as shown in FIG. 5, after adjusting the atomization amount of the first operation to the required atomization amount in the next operation, for example, weekly, monthly, yearly, etc. The calculation means 12 calculates the atomization amount as described above at regular intervals such as the above, determines whether it is the necessary atomization amount, switches the switching unit 222 as necessary, updates the value, and records it. The setting is performed by the periodic switching setting unit 223B.

  As described above, the relationship between the atomization amount with respect to the applied voltage due to the oscillation operation of the components (for example, transistors) of the mist device 3 is a constant gradient value, and the relationship between the first detection means 42 and the second detection means 43 of the water storage tank 4. The amount of atomization per unit time can be grasped from the amount of water reduced due to the difference in water level and the time measured value by the timer means 11, and the constant rate value of the necessary voltage switching can be calculated from the constant gradient value. Conventionally, since there are variations in the components of the mist device 3 and the power supply unit 2, it is not possible to know which atomization amount the initial state is, so it is necessary to consider component selection and combination for each washing dryer 6. What was there can be automatically made the atomization amount within the required range (required atomization amount range upper limit value J1 to required atomization amount range lower limit value J2 in FIG. 4).

  Further, by calculating and adjusting the atomization amount at regular intervals of the regular switching unit 223B, the necessary atomization amount can be maintained even if there is a secular change or a change in the surrounding environment.

  FIG. 2 shows an example of the power supply unit 2 in detail. The output Z1 (waveform of FIG. 3A) obtained by smoothing the alternating current by the smoothing unit 213 from the input of the commercial power supply is set to a constant frequency by the switching circuit 211. The output is Z2 (waveform in FIG. 3B) that is switched and stabilized to the power supply voltage to the mist device 3 via the transformer 212. At that time, the output side voltage of the transformer 212 is monitored by the feedback circuit 224, compared with a constant voltage value generated by the reference voltage unit 221, and the switching circuit 211 is controlled to stabilize the voltage.

  In this example, the resistance values are set to different values so that the constant voltage value generated in the reference voltage unit 221 is switched at a constant rate, and switching from A to D is performed by the switching setting unit 223. Record.

  In the details of the power supply unit 2 in FIG. 2, there are two types of cases where a DC voltage is provided after the switching circuit 211 of the stabilization function 21 as a power supply to be applied to the mist device 3, and voltage waveforms when provided. 3 (b), and a constant voltage is output regardless of the frequency and voltage change of the commercial power supply. Therefore, the relationship between the atomization amount and the applied voltage is the constant slope value (for example, H2) in FIG. As stable.

  However, the voltage waveform when not provided is the voltage waveform of (a) of FIG. 3, the ripple interval is different at commercial frequencies of 50 Hz and 60 Hz, and the output voltage value has an influence on the voltage change of the commercial power supply, The constant slope value (eg, H2) in the voltage diagram 4 is not stable. Therefore, the command to the switching setting unit 223 for voltage adjustment performed by the adjustment unit 22 may not be correctly performed, and it takes time to adjust the adjustment unit 22.

  Therefore, the voltage can be adjusted accurately and quickly by using the voltage waveform shown in FIG.

  Here, the voltage stabilization function 21 of the power supply unit 2 will be described as a switching power supply, but the same operation and action are achieved even with other DC power supplies. Although the switching unit 222 has described the voltage switching at a certain ratio by the switching method of the voltage dividing ratio by the resistance value, the switching method using a Zener diode or the like is the same.

  The atomization generating unit 31 is an ultrasonic vibrator here, but the operation, operation, and effect are the same as long as it is an oscillating element such as a piezoelectric element.

  As described above, the washing / drying machine according to the present invention can reduce the selection and combination due to component variation as much as possible, thereby improving productivity and reducing cost.

  This is not only inexpensively used for improving performance such as washing, drying, and sterilization, but also for household appliances such as washing dryers, dishwashers, refrigerators, air purifiers, and equipment installed in buildings and factories. It can be applied to other uses.
