Description

Electrical equipment with drying function

The present invention relates to an electric device, and more particularly to an electric device having a drying function.

Conventionally, dryers that irradiate light into the washing tub have been proposed. For example, Japanese Patent Application Laid-Open No. 10-244099 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2003-62383 (Patent Document 2) disclose a technique for irradiating clothes being dried with infrared rays in order to improve drying efficiency. Yes. Japanese Utility Model Laid-Open No. 2-82290 (Patent Document 3) discloses a configuration in which a sun lamp (mercury lamp) is incorporated in a dryer in order to irradiate laundry with light like the sun. Japanese Utility Model Laid-Open No. 60-16497 (Patent Document 4) discloses a dryer incorporating an ultraviolet or infrared light emitter.

Also, conventionally, after the drying process of the laundry dryer, which is an example of an electric device having a drying function, in order to improve the finish of the clothes to be dried, the state of the laundry is determined and the drying operation is terminated. A washing machine has been proposed. The state of the laundry here refers to the degree of drying, the temperature, etc., which indicate the degree of drying of the clothes after drying. In Patent Document 5 (Japanese Patent Laid-Open No. 2010-240007), an electrode is provided in a rotating drum, and the drying degree is controlled by detecting the degree of drying of the clothes from the resistance value of the electrodes in contact with the clothes. In Patent Document 6 (Japanese Patent Laid-Open No. 2014-10000174), the dryness is determined based on the temperature difference between the intake air and the exhaust gas, and the dryness is displayed and notified to the user. In Patent Document 7 (Japanese Patent Application Laid-Open No. 2004-248806), the temperature in the washing tub is detected and controlled so that the temperature in the washing tub does not exceed 75 ° C. Further, in Patent Document 8 (Japanese Patent Laid-Open No. 2003-311098), moisture is imparted to an object to be dried during the drying process in order to prevent wrinkles and the like and improve the finished state of the clothes.

Japanese Patent Laid-Open No. 10-244099 JP 2003-62383 A Japanese Utility Model Publication No. 2-82290 Japanese Utility Model Publication No. 60-16497 JP 2010-240007 A JP 2014-1000017 A Japanese Patent Laid-Open No. 2004-248806 Japanese Patent Laid-Open No. 2003-311098

In the prior arts disclosed in Patent Documents 1 to 4, the main purposes of irradiating light into the washing tub include improvement of drying efficiency, improvement of operability, and provision of a sterilizing effect. In recent years, some people are hesitant to dry laundry outdoors by sun-drying, mainly due to air pollution caused by PM2.5. Therefore, it has become mainstream to dry clothes using a washing and drying machine which is a washing machine with a drying function. However, there is a current situation that it is difficult to give the user sufficient satisfaction in the finish of drying.

That is, since the inside of the washing / drying machine is dark and cannot be seen well, it is difficult for the user to get a sense that the clothes are being dried. In view of such a situation, the inventors sought a point of user satisfaction in the dry finish. As a result, the user feels “soft”, “comfortable”, “warmth”, “cleanliness”, “does it dry well”, “good finish”, “feels like drying in the sun” The knowledge that the finish of the drying of the laundry was judged by items such as. At the same time, the user has a very “good image” that resembles “memory” such as the feeling of “sun-dried” or “yearning”, and “memory and good image of sun-dried”. In comparison with the above, it is known that the above-described prior art is significantly less satisfied. That is, in the conventional technique, measures corresponding to the points of satisfaction of these users are not sufficiently taken. Therefore, in the conventional technique, the degree of satisfaction of the users with respect to the finished drying of the laundry is low.

In the prior arts disclosed in the above Patent Documents 5 to 8, in order to improve the finish of the clothes after drying, the end of drying is determined based on the temperature or the dryness. It is not defined whether the state is acceptable. For example, when trying to dry clothes completely, even if it finishes at high temperature, it will be in a so-called overdried state, and clothes may shrink or the touch may be stiff. On the other hand, even if moisture is applied to improve the finished state, the user may feel insufficient drying.

Actually, there are a heater type and a heat pump type in the currently proposed washer / dryer. However, the heater type has a problem that the user feels too hot after finishing at a high temperature. On the other hand, in the heat pump type, there is a problem that the user feels that the clothes after drying do not satisfy a sufficient degree of dryness and the user does not dry well, instead of being as hot as the heater type.

Therefore, an object in an aspect of the present disclosure is to provide an electric device that can give a user a satisfaction level of drying finish.

Next, the irradiation light from the light irradiation unit 9 in the light irradiation process described above will be described. FIG. 6 is a diagram showing details of the vicinity of the black body radiation locus V0 in the xy chromaticity diagram defined by the International Commission on Illumination. In FIG. 6, a uniform color temperature line group and a uniform deviation line group with respect to the black body radiation locus V0 are described in an overlapping manner. The light emitted from the light source of the light irradiating unit 9 is represented by an equal deviation line V1 with respect to a color matching temperature line W1 passing through a point A (0.519, 0.478) and a black body radiation locus V0 on the xy chromaticity diagram. , Corresponding to the light in the region S surrounded by the equal color temperature line W2 passing through the point B (0.403, 0.376) and the equal deviation line V2 with respect to the black body radiation locus V0.

Point A shows a point where the correlated color temperature is 2450K and the deviation uv = 0.167 with respect to the blackbody radiation locus V0. Point B represents a point having a correlated color temperature of 3410 K and a deviation uv = −0.0055 with respect to the blackbody radiation locus V0. The chromaticity coordinates of the intersection C between the equal color temperature line W1 and the equal deviation line V2 are (0.461, 0.389), and the chromaticity at the intersection D between the equal color temperature line W2 and the equal deviation line V1. The coordinates are (0.429, 0.449). Accordingly, the region S is surrounded by points A, C, B, and D in the clockwise direction in the drawing. Region S indicates yellow, yellowish orange, orange, red-orange, or orange-pink. The light source of the light irradiation unit 9 according to Embodiment 1 emits yellow, yellowish orange, orange, red-orange, and orange-pink light. The yellow or orange color included in these colors is a color that gives an image of brightness, warmth, and light in color psychology, and has been known as a color that gives the image of the sun since ancient times. Note that the light source of the light irradiation unit 9 may emit light having a wavelength of 570 nm to 620 nm in order to emit yellow or orange colors.

When the washing / drying machine 1 performs the drying process by the drying process control unit 204, the light irradiation process control unit 200 performs the light irradiation process. FIG. 7 is a diagram schematically illustrating an example of the timing at which the light irradiation unit 9 according to Embodiment 1 emits light during the drying process. In FIG. 7, patterns 1 to 5 are shown as the timing of light irradiation by the light irradiation process control unit 200.

In the pattern 1 of FIG. 7A, light is continuously irradiated during the drying process. Specifically, the light irradiation process control unit 200 controls the light irradiation unit 9 so that light is emitted during the drying process of the washing dryer 1. More specifically, the light irradiation unit 9 starts emitting light simultaneously with the start of the operation of the heat pump unit 7 and / or the heater unit 8 (that is, at least one of the heat pump unit 7 and the heater unit 8), and the heat pump unit 7 And / or the light is continuously emitted until the operation of the heater unit 8 ends.

In pattern 2 in FIG. 7B, light is irradiated only for a predetermined period of time at the beginning of the drying process. For example, the light irradiation process control unit 200 controls the light irradiation unit 9 so that light is continuously irradiated for a predetermined time from the start of the operation of the heat pump unit 7 and / or the heater unit 8. After the lapse of a certain time, the light irradiation process control unit 200 may control the light source of the light irradiation unit 9 to be turned off. Note that the light irradiation process control unit 200 may control the light irradiation unit 9 so that light is emitted intermittently during the certain time of the pattern 2.

7C, the light irradiation process control unit 200 controls the light irradiation unit 9 so that light is irradiated only for a predetermined time in the latter half of the drying process. Alternatively, the light irradiation process control unit 200 controls the light irradiation unit 9 so as to emit light continuously for a certain period of time before the operation of the heat pump unit 7 and / or the heater unit 8 ends.

In the pattern 4 of FIG. 7D, the light irradiation process control unit 200 emits light at the first predetermined first time and the second predetermined second time in the second half of the drying process. The light irradiation unit 9 is controlled. Alternatively, the light irradiation process control unit 200 irradiates the light continuously for the first predetermined time from the start of the operation of the heat pump unit 7 and / or the heater unit 8 and then turns off the light irradiation unit 9. Then, the light irradiation unit 9 may be controlled so as to emit light continuously for the second predetermined time before the operation of the heat pump unit 7 and / or the heater unit 8 ends.

Note that the lengths of the first fixed time and the second fixed time may be the same or different.

7E, the light irradiation process control unit 200 controls the light irradiation unit 9 so that light is intermittently irradiated in the drying process. With reference to pattern 5, the timing at which light irradiation unit 9 emits light may be linked to the operation of heat pump unit 7 and / or heater unit 8, for example. Specifically, as shown in FIG. 7E, when the heat pump unit 7 operates continuously during the drying process and the heater unit 8 operates intermittently during the drying process, the light irradiation process control unit 200 may control the light irradiation unit 9 so that light is irradiated only when the heater unit 8 operates. Or although not shown in figure, when the heater part 8 operate | moves continuously during a drying process and the heat pump part 7 operate | moves intermittently during a drying process, for example, the light irradiation process control part 200 is the heat pump part 7 The light irradiator 9 may be controlled so that light is emitted only when is operated.

When light is continuously emitted from the light irradiation unit 9 during the drying process (see pattern 1 in FIG. 7), the image of “sun-dried” can be imparted to the user at any time by light. On the other hand, when light is emitted intermittently from the light irradiation unit 9 (see pattern 2 to pattern 5 in FIG. 7), light irradiation is performed at a time when the user may stay near the washing / drying machine 1. Since light is emitted from the unit 9, energy saving and long life of the light source can be realized.

In particular, in the

patterns

4 and 5 in FIG. 7, light is emitted from the light irradiation unit 9 at a time when the user may stay near the laundry dryer 1, and the user is near the laundry dryer 1. Since light is not emitted from the light irradiation unit 9 at a time when the possibility of staying is low, the life of the light source can be prolonged as compared with the

patterns

2 and 4.

The light emitted from the light irradiating unit 9 brightens the visual field inside the drum 3 of the washing / drying machine 1 by the light scattering means 10 (door body), and is diffused to the outside through the front door 11. With this configuration, the user can check the state of the clothes 55 irradiated with light in the drum 3. In addition, when light diffuses outside the washing / drying machine 1, an image of “sun drying” can be given to the user.

[Embodiment 2]

In the first embodiment described above, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light in the drying process, but in the second embodiment, the light irradiation process control unit 200 emits light in the washing process. The light irradiation unit 9 is controlled.

FIG. 8 is a diagram schematically illustrating an example of the timing at which the light irradiation unit 9 according to Embodiment 2 emits light during the washing process. In FIG. 8, patterns 6 to 8 are shown as the timing of light irradiation.

In the pattern 6 in FIG. 8A, the light irradiation unit 9 continuously emits light during the washing process. Specifically, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light continuously in the washing process (that is, all of the washing process, the rinsing process, and the dehydration process).

8B, in the pattern 7, the light irradiation unit 9 intermittently emits light during the washing process. For example, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light during the washing process and the rinsing process in the washing process.

Alternatively, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light during the rinsing process and the dehydration process in the washing process, or during the washing process and the dehydration process in the washing process. .

Alternatively, the light irradiation process control unit 200 controls the light irradiation unit 9 so that light is emitted during any of the washing process, the rinsing process, or the dehydration process.

In the pattern 8 shown in FIG. 8C, the light irradiation unit 9 emits light intermittently in the cleaning process. Here, for example, in the washing process and the rinsing process, the washing / drying machine 1 starts water supply to the drum 3, and after the water supply ends, the drum 3 performs a tumbling operation, and then drains from the drum 3. To do. For example, in the cleaning process, as shown in FIG. 8C, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light simultaneously with the start of the tumbling operation, and turns off the light simultaneously with the start of drainage. Alternatively, the light irradiation unit 9 may be controlled. The pattern of FIG. 8C can be similarly applied in the rinsing process.

In the dehydration process, the light irradiation process control unit 200 emits light at the same time as the drum 3 starts rotating for dehydration, and the rotation for dehydration ends (or the washing tub drive that rotates the drum 3). The light irradiation unit 9 may be controlled so that the light is turned off at the same time as the operation of the motor 4 ends.

For example, when the washing / drying machine 1 has a sterilization function, the light irradiation process control unit 200 controls the light irradiation unit 9 to emit light while the sterilization is being performed. Also good. In carrying out the sterilization, for example, a function of releasing ions (silver ions) for sterilization into the drum 3 can be used. Further, an ion generator (not shown) for generating positive and negative ions in the air passage 6 may be provided. In the ion generator, a needle-like discharge electrode (not shown) is provided so as to be exposed in the air passage, and discharge is performed by supplying an AC waveform or impulse waveform voltage to the discharge electrode from a power feeding unit (not shown). The electrode generates ions.

When the voltage applied to the discharge electrode is a positive voltage, ions combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) _m . When the applied voltage of the discharge electrode is a negative voltage, the ions are combined with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) _n . Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n aggregate on the surface of airborne bacteria and odorous components and surround them.

Then, as shown in (Formula A) to (Formula C), [· OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide), which are active species, are agglomerated and produced on the surface of a microorganism or the like by collision. To destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, the sterilization and odor removal of the drum 3 and clothes can be performed by generating positive ions and negative ions.

^{_{_{H + (H 2 O) m}}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ··· ( formula A)
H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ′} + O ₂ ⁻ (H ₂ O) _n + O ₂ ⁻ (H ₂ O) _{n ′}
→ 2.OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (Formula B)
H ⁺ (H ₂ O) _m + H ⁺ (H ₂ O) _{m ′} + O ₂ ⁻ (H ₂ O) _n + O ₂ ⁻ (H ₂ O) _{n ′}
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (formula C). In this embodiment, positive ions and negative ions are generated by the ion generator, but only negative ions may be generated.

FIG. 12 is a diagram showing the result of subjective evaluation by Experiment 1. In FIG. In FIG. 12, the result of a subject's subjective evaluation is shown about two cases, the case where the light of (Example 9) is turned on by the light irradiation part 9, and the case where it is not so. In FIG. 12, the case where there is a significant difference in improvement with a significance level of 5% when the light is turned on when the light is not turned on (no light irradiation to the outside through the door) is “X1”. When the significance probability is less than 10%, “X2” indicates that there is a tendency of improvement, and “X3” indicates that there is no significant difference or tendency of improvement.

As a result, the

evaluation items

1, 2, 4, 7 and 8 of the drying process are “soft”, “comfortable”, “clean”, “feeling like sun-dried”, and “easy to take out” Evaluation was made at a significance level of 5% for each evaluation content. In Experiment 1, when the light irradiation part 9 was turned on and the said evaluation was implemented, the test subject's subjective feeling about the

evaluation items

1, 2, 4, 7, and 8 showed the tendency to improve. In addition, there was a tendency for the subjective feeling to improve with respect to the

evaluation items

When the illumination light at points p1 to p9 of Examples 1 to 9 in the range of the region S is turned on, the significance level is 5% and the significance level is less than 10% as compared with the case where the illumination light is not turned on. There was a tendency for the subjective content to be improved in the evaluation contents.

On the other hand, when the illumination light of points q1 to q7 in Comparative Examples 1 to 7 outside the region S is turned on, there is a significant difference in improvement of subjective feeling in most evaluation contents compared to the case where the illumination light is not turned on. And there was no trend. Thus, according to FIG. 13, the critical significance regarding the value of the region S is also shown.

From the above experimental results, it was shown that the subjective satisfaction with the finish of the laundry (clothing 55) is increased when there is external light irradiation during the drying process. More specifically, it was shown that when the light color in the range of the region S is irradiated, the subjective satisfaction with respect to the finish of the laundry (clothing 55) is increased. In addition, it was shown that the satisfaction of “cleanliness” can be enhanced when there is external light irradiation in the washing process. More specifically, it has been shown that when the clothing 55 is irradiated with light of a color in the range of the region S, the subjective satisfaction with respect to the finished laundry (clothing 55) is increased. Further, when the clothes 55 are put in and taken out and the door is opened, the light irradiation unit 9 is turned on to illuminate the inside of the drum 3, mainly for the ease of the putting-in operation and the ease of taking-out operation. Increased satisfaction was shown.

In each of the embodiments described above, laundry such as clothing 55 is given as an example of a drying target, but bedding such as a futon may be used. In addition, the drum-type washing / drying machine 1 has been exemplified as an apparatus having a drying function, but a vertical washing / drying machine may be used, and a drying machine (a large-scale drying machine used in a household drying machine or a coin laundry, a futon) Drying machine).

Further, the position of the light source of the light irradiation unit 9 is not fixed, and the light emission direction may be changed manually. In this case, a motor may be provided in association with the light irradiation unit 9, and the CPU 23 may control the motor so that the light irradiation direction is changed in conjunction with the rotation of the motor.

To do. The gas flowing into the air passage 6 from the exhaust port 32 through the other end of the tube of the air passage 6 is dried by being condensed (dehumidified) by the heat pump unit 7. Thereafter, the dried gas is heated by the heater unit 8 and sent to the air supply port 31 through one end of the tube. The heater unit 8 and the heat pump unit 7 are an example of a “heat drying unit” that performs heat drying of such a gas. The gas after drying and heating is sent into the drum 3 by the blower 50 through the air passage 6 and the air supply port 31. Thereby, warm air is supplied into the drum 3. In addition, although the drying method by the heat pump was applied to the washing dryer 1000, the heater type which dries the clothing 55 only with a heater may be used.

Output.

Since the circuit connected to the load drive circuit 37 is the same as that described in FIG. 4, the description will not be repeated.

FIG. 16 is a block diagram schematically showing functions of the CPU 23 according to the eighth embodiment. Referring to FIG. 16, CPU 23 includes a washing process control unit 201 and a drying process control unit 204. The washing process control unit 201 includes a cleaning process control unit 220, a rinsing process control unit 221, and a dehydration process control unit 222. The functions of these units are realized by hardware and software (program and data) executed by the CPU 23. Such software is stored in advance in the RAM 24 and the ROM 25.

The ROM 25 stores a plurality of tables 251, tables 252, and tables 253. The plurality of tables 251 include tables 251 corresponding to different materials (cotton, chemical fibers, etc.) of the entire clothing 55 to be dried. In each table 251, a temperature t (unit: ° C.) and a humidity H (unit: grams / cubic meter) are registered in association with each weight of the clothing 55.

The temperature t and the humidity H are detected from the airflow (warm air) sent out from the exhaust port 32 when the clothing 55 of the corresponding material and weight is appropriately dried in the drum 3 in the drying process. Indicates temperature and humidity. In the table 251, data acquired in advance through experiments is registered. Details of the data registered in the table 251 will be described later.

The table 252 and the table 253 are registered with temperature and humidity data regarding the drying object when the towel is included in the clothing 55. Details of the data will be described later.

The functions and configurations of the washing process control unit 201, the washing process control unit 220, the rinsing process control unit 221 and the dehydration process control unit 222 have the same functions and configurations as those of the washing / drying machine 1 described in the first embodiment. Therefore, the description is not repeated here (control by the drying process control unit)
The drying process control unit 204 includes a washing tub drive motor 4, a washing water supply valve 38, a fan motor (not shown) for rotating a fan of the blower 50, and a heat pump unit so as to perform the drying process in the drum 3. 7 and the heater unit 8 are controlled. In the drying process, the clothes 55, which is an object to be dried, in the drum 3 is dried after moisture is removed. Here, although the clothing 55 is the drying object, the clothing 55 is not limited to the clothing 55, and can be a general fabric product.

After starting the drying process, the drying process control unit 204 determines the end of the drying process based on whether a predetermined condition using the detection values of the temperature detection unit 601 and the humidity detection unit 602 is satisfied. .

The drying process by the drying process control unit 204 will be described. When the drying process is started, the washing tub drive motor 4 starts rotating the drum 3 according to the control of the CPU 23. The rotation speed of the drum 3 is controlled based on the rotation chart for the drying process. While the drum 3 is rotating, the fan 50 is operated by the fan motor. By these operations, the air in the drum 3 passes through the exhaust port 32, the air passage 6, the blower 50, the heat pump unit 7, the heater unit 8, and the air passage 6 in this order, and returns to the drum 3 from the air supply port 31. It is. The air thus circulated is heated and dried by the heat pump unit 7 and the heater unit 8 and supplied to the drum 3 as warm air, and the clothes 55 in the drum 3 are gradually dried by the warm air.

In the drying process, moisture evaporated from the clothes 55 is included in the gas sent from the exhaust port 32 of the drum 3 to the air path 6. When the wet gas passes through the heat pump unit 7, it is cooled and condensed by the evaporator, heated by the condenser, and further heated by the heater unit 8 as necessary, and sent to the air path 6. The In addition, the condensed water | moisture content is discharged | emitted outside through the drainage duct which is not shown in figure. The drying process can be performed until a stop operation from the operation panel 12 or the CPU 23 determines that the drying is finished. In the eighth embodiment, the drying process is not a stop operation by the user from the operation panel 12 but ends when the CPU 23 determines that the above condition is satisfied.

(Processing for controlling the end of the drying process)
FIG. 17 is a flowchart showing an outline of a process for controlling the end of the drying process according to the eighth embodiment. A program according to this flowchart is stored in the ROM 25. The CPU 23 reads the program from the ROM 25 and executes the read program to realize the processing.

First, clothes 55 are stored in the drum 3 and the door is closed. Therefore, the inside of the drum 3 is in a sealed state. When starting the drying process, the CPU 23 acquires parameters for controlling the drying process (step S1).

The parameter includes the weight W2 (unit: gram) of the clothing 55 that is the material to be dried in the drum 3. The weight W2 is the weight of the garment 55 that is actually put into the drum 3. When the clothes 55 do not include clothes intentionally containing moisture, the weight W of the absolutely dry clothes 55 and the weight W2 of the clothes 55 actually put into the drum 3 are regarded as the same, Drying control is performed according to the amount of clothing from the value of the weight W2. The completely dry state indicates a state in which moisture has been completely removed from the fibers of the garment 55. Examples of intentionally moistened water include wet rags and towels, clothing that has been directly sprayed with water by partial washing, and general fibers that are clearly wet when touched. The weight W2 can be acquired from a value measured by the weight sensor 117 provided in association with the drum 3 or a value input by the user via the operation panel 12, but the acquisition method is not limited to this. The material Q indicates the material of the clothing 55 fiber (100% cotton, 100% chemical fiber, blend of cotton (65%) and chemical fiber (35%), etc.).

The drying process is performed by the drying process control unit 204 (step S3). Thereby, the dried and heated gas becomes warm air and is supplied into the drum 3 through the air supply port 31, and the clothes 55 in the drum 3 are gradually dried by the warm air. Further, the gas circulated in the drum 3 is sent into the air path 6 through the exhaust port 32.

The humidity and temperature in the drum 3 are detected (measured) by the temperature detection unit 601 and the humidity detection unit 602 arranged in the air path 6 (step S5). Based on the above parameters, the CPU 23 searches the ROM 25 for a table 251 corresponding to the parameter (material), and reads the temperature t and the humidity H associated with the parameter (weight of the clothing 55) from the table 251 ( Step S7).

The CPU 23 detects the temperature t read from the table 251 by the temperature detection unit 601 based on the detection values of the temperature detection unit 601 and the humidity detection unit 602, and the humidity read from the table 251 by the humidity detection unit 602. When it is determined that H is detected, it is determined that the condition for finishing drying is satisfied (YES in step S9). In the eighth embodiment, the temperature t is indicated by a predetermined range of temperature (temperature range), and the humidity H is also indicated by a predetermined range of humidity (humidity range). Therefore, the CPU 23 compares the detected temperature and humidity of the temperature detecting unit 601 and the humidity detecting unit 602 with the temperature t and humidity H of the table 251 respectively, and based on the comparison result, the detected temperature falls within the range of the temperature t. It is judged whether or not the detected humidity falls within the range of the humidity H. Based on the determination result, it is determined whether or not a condition for finishing drying is satisfied.

When the CPU 23 determines that the detected temperature falls within the range of the temperature T and the detected humidity falls within the range of the humidity H, that is, determines that the condition for finishing drying is satisfied (YES in step S9). The operation of the heat pump unit 7 and the heater unit 8 is stopped (step S11). As a result, the supply of warm air into the drum 3 is stopped, and the drying process ends.

Note that when the CPU 23 determines that the above-described drying termination condition is not satisfied (NO in step S9), the process returns to step S5 to continue the drying process, and the subsequent processes are similarly repeated.

(Data in table 251)
Data of the table 251 searched by the CPU 23 when determining the end of the drying process described above (step S9) will be described.

Here, for the sake of explanation, temperature T and dryness K representing the temperature and dryness of the entire clothing 55 are used. The temperature t and humidity H of each table 251 are determined by the values of the temperature T and the drying degree K at the end of the drying process of the entire clothing 55. Specifically, the temperature t and the humidity H indicate that the temperature T of the entire garment 55 is an appropriate temperature (hereinafter also referred to as a target temperature) after the drying process is started, and the dryness K of the entire garment 55 is appropriate. The temperature detected by the temperature detection unit 601 and the humidity detected by the humidity detection unit 602 are shown respectively when the dryness (hereinafter also referred to as target dryness) is shown. When the entire garment 55 is at an appropriate temperature and at an appropriate dryness, the garment 55 is in an appropriate finish.

Drying degree K is represented by an equation of K = D × (weight W / weight W1). In this equation, the coefficient D indicates a value determined by the material of the garment 55 (an object to be dried), the weight W indicates the weight of the garment 55 in an absolutely dry state, and the weight W1 indicates that the garment 55 is appropriately dried as described above. It shows the weight of the clothing 55 as a whole. Details of the method for determining the appropriate temperature T corresponding to the target temperature described above and the appropriate dryness K corresponding to the target dryness will be described later.

In this embodiment, for example, the table 251 is a single unit similarly to the table 251 corresponding to the material Q in which the fibers of the entire clothing 55 composed of a plurality of fiber structures are composed of 65% cotton and 45% synthetic fiber. The table 251 corresponding to the material Q of 100% cotton composed of the above fiber structure and the table 251 corresponding to the material Q of 100% synthetic fiber composed of a single fiber structure are included. Each table 251 corresponds to each divided weight in the range of 2 kg to 6 kg of the entire clothing 55 (for example, 2 to 3 kg, 3 kg to 4 kg, 4 kg to 5 kg, 5 kg to 6 kg, respectively), Temperature t and humidity H are registered.

Here, with respect to the appropriate temperature T and the appropriate dryness value K described above, with reference to FIG. 18, the appropriate finished state of the garment 55 by the drying process of the washing dryer 1000 according to the eighth embodiment. explain. FIG. 18 shows, as an example, a case where the material Q of the fiber of the entire garment 55 is composed of a blend of 65% cotton and 45% synthetic fiber.

FIG. 18 shows a two-dimensional coordinate system defined by a dryness K coordinate axis (vertical axis) and a temperature T coordinate axis (horizontal axis) orthogonal to the coordinate axis. According to the experiment described later, in the drying process of the washing / drying machine 1000, coordinate values satisfying the conditions of (1.01 / D ≦ K / D ≦ 1.05 / D) and 45 ° C. ≦ T ≦ 60 ° C. (FIG. 18), the garment 55 was in an appropriate finish. The appropriate finished state is based on the evaluation of the touch comfort of the garment 55 based on the subjectivity of the user (human), as will be shown in an experiment described later.

In the experiment, the detection temperature t detected by the temperature detection unit 601 and the detection humidity H detected by the humidity detection unit 602 when this condition is satisfied are sampled for each weight category of the garment 55, and stored in the table 251 corresponding to the material Q in the weight category. Correspondingly registered.

As described above, the CPU 23 ends the drying process when the temperature t and the humidity H when the finish state is appropriate based on the user's subjectivity are detected. Therefore, the evaluation by the user of the touch comfort of the clothes 55 after drying (such as “good warmth” and “good touch”) can be improved as compared with the conventional case. As a result, it is possible to improve the user's satisfaction with the clothes 55 after drying.

Note that, according to the above-described experiment, D = 1.08 and K = (1.08 × W) / W1 when the fiber of the entire garment 55 is 100% cotton in the completely dry fiber. Similarly, in the case of 100% synthetic fiber, D = 1.004 and K = (1.004 × W) / W1. In the case of a blend of 65% cotton and 45% synthetic fiber, K = (1.08 × (0.65 × W) + 1.004 × (0.35 × W)) / W1.

[Embodiment 9]
The ninth embodiment shows a modification of the eighth embodiment. In Embodiment 9, when towel (100% cotton) is included in clothing 55, the target dryness includes the target dryness of the towel, and the target temperature includes the target temperature of the towel. In the ninth embodiment, the data in the table 252 is referred to in order to determine that the drying state of the towel has become an appropriate finished state in the drying process, that is, to determine whether or not to end the drying process. The

Referring to FIG. 19, an appropriate finished state of clothing 55 including towels by the drying process of washing dryer 1000 according to Embodiment 9 will be described. FIG. 19 shows a case where the garment 55 includes a plurality of towels and the towel occupies a weight of approximately 13% or more and 30% or less with respect to the total weight of the garment 55. As an example, the towel included in the garment 55 is 100% cotton, the width is approximately 34 cm, the length is approximately 85 cm, and the weight in an absolutely dry state is approximately 90 g or more and 110 g or less.

FIG. 19 is a diagram showing a two-dimensional coordinate system determined by the coordinate axis (vertical axis) of the dryness K1 and the coordinate axis (horizontal axis) of the temperature T1 orthogonal to the coordinate axis. According to the inventor's experiment, in the drying process of the washing / drying machine 1000, a point A (1.045, in the coordinate system of FIG. 45 ° C.), point B (1.045, 50 ° C.), point C (1.075, 65 ° C.) and point D (1.075, 45 ° C.) When the coordinate value was measured, the towel of the garment 55 was in an appropriate finish.

In the experiment, the temperature t detected by the temperature detector 601 and the humidity H detected by the humidity detector 602 when this condition is satisfied are sampled and registered in the table 252.

Also in Embodiment 9, the process of FIG. 17 is performed during the drying process. Here, the processing of step S7 and step S11, which is different from that of the eighth embodiment, in the processing of FIG. 17 will be described. Since the other processes in FIG. 17 are the same as those in the eighth embodiment, description thereof is omitted.

In step S7 of FIG. 17, the CPU 23 searches the table 252 according to the towel drying mode designated via the operation panel 12 when starting the drying process, and reads the temperature t and the humidity H. When the humidity H of the table 252 is detected by the temperature detection unit 601 and the temperature t of the table 251 is detected by the humidity detection unit 602, the CPU 23 determines that the drying end condition is satisfied (in step S9). YES), the drying process is terminated (step S11).

Therefore, the evaluation by the user of the touch feeling of the towel included in the clothes 55 at the end of the drying process (or after the end) (“goodness of warmth”, “goodness of touch”, etc.) is improved compared to the conventional case. be able to. As a result, it is possible to improve the user's satisfaction with the clothes 55 after drying.

[Embodiment 10]
The tenth embodiment shows a modification of the ninth embodiment. An appropriate finished state corresponding to the value of the shaded area in FIG. 19 is a dry and dry state. However, some users prefer a moist touch even when dry. In the tenth embodiment, a configuration for meeting such a user's request is shown.

According to the inventor's experiment, in the coordinate system of FIG. 19, the regions that meet the request are points (1.035, 45 ° C.), points (1.035, 70 ° C.), points (1.05, 70 ° C.). It was found that the region ER2 is surrounded by three points. FIG. 23 is a diagram showing an area ER2 corresponding to a combination (K, T) of the dryness K and the temperature T for obtaining an appropriate finished state according to the tenth embodiment. FIG. 23 also shows, for reference, an area ER1 of a combination (K, T) for obtaining an appropriate finished state in the experiment of the ninth embodiment. In the third embodiment, in the experiment, the detection temperature t by the temperature detection unit 601 and the detection humidity H by the humidity detection unit 602 when the combination (K, T) in the region ER2 is detected are sampled and stored in the table 253. be registered.

Also in the tenth embodiment, the process of FIG. 17 is performed during the drying process. Here, the processing of step S7 and step S11, which is different from that of the eighth embodiment, in the processing of FIG. 17 will be described. Since the other processes in FIG. 17 are the same as those in the eighth embodiment, description thereof is omitted.

17, the CPU 23 searches the table 253 according to the towel moist drying mode designated via the operation panel 12 at the start of the drying process, and reads the temperature t and the humidity H. When the humidity H of the table 253 is detected by the temperature detection unit 601 and the temperature t of the table 251 is detected by the humidity detection unit 602, the CPU 23 determines that the drying end condition is satisfied (in step S9). YES), the drying process is terminated (step S11).

Therefore, in the touch feeling of the towel included in the clothes 55 at the end of the drying process (or after the end), “softness” and “moist feeling” are increased as compared with the finished state of the ninth embodiment. The user's satisfaction can be improved for the user who likes the finished finish.

[Experiments for touch evaluation]
In order to evaluate the touch comfort of the garment 55 in each of the eighth to tenth embodiments, the inventor applied the touch comfort of the garment 55 for a total of 10 combinations (K, t) of the dryness K and the temperature t of the garment 55 as a whole. Evaluated. In addition, the clothing 55 used as the evaluation object included a towel, and the touch feeling was evaluated for the towel. The point having the highest score among these 10 points was set as a reference point (corresponding to the reference point M in FIG. 18). Then, in order to evaluate the touch comfort of the reference point M, an experiment was performed comparing the touch comfort evaluation of the reference point M with the touch comfort evaluation according to Examples 1 to 4 described later. In addition, in order to evaluate the tactile sensation according to Examples 1 to 4, an experiment was performed in which the tactile sensation evaluation of the reference point M was compared with Comparative Examples 1 to 5 described later.

For each embodiment, in order to evaluate the touch comfort of the towel taken out from the clothes 55 dried by the washing / drying machine 1000, the inventor measured the average value K ′ and the temperature of the dryness of the six towels taken out. The towel touch feeling was evaluated for a total of 10 combinations (K ′, t ′) of average values t ′. The point with the highest score among these 10 points was defined as a reference point (corresponding to the reference point N in FIG. 19). Then, in order to evaluate the touch feeling of the reference point N, an experiment was performed comparing the touch feeling evaluation of the reference point N with Examples 5 to 8 described later. In addition, in order to evaluate the tactile sensation according to Examples 5 to 8, an experiment was performed comparing the tactile sensation evaluation of the reference point N with Comparative Examples 6 to 10 described later.

Hereinafter, these comparison experiments will be described. In FIG. 18, the reference point M and the combinations (K, T) of Examples 1 to 4 are indicated by points P to S. Further, each combination (K, T) of Comparative Examples 1 to 5 is indicated by points v1 to v5.

(About evaluation contents)
In the experiment, 10 male and 8 female subjects were subjected to 10 drying processes, the touch of the entire clothing 55 finished by each drying process, and towels were extracted from the clothing 55 to extract towels. The touch feeling was evaluated. As shown in FIG. 20, the evaluation contents are “just good warmth”, “good touch”, “soft”, “wet and dry” and “soft” divided into items 1 to 5 .

The evaluation method for the contents of items 1 to 5 is a subjective evaluation based on the subjectivity of each subject. That is, as an evaluation method, VSA (Visual Analogue Scale) used for evaluating the intensity of sensation / emotion was used. In this evaluation method, on one straight line that represents the worst sense at one end and the best sense at the other end, a mark is applied to the point adapted to the strength of the sense and emotion for the evaluation content felt by the subject at that time. By measuring the length from the position of the mark to one end, the subjective feeling is quantified and evaluated by the score.

(Experiment for Embodiment 8)
In the experiment, the combination of dryness and temperature (K, T) is detected in the washer / dryer 1000 at four points P to S in FIG. 18, five points indicated by points v1 to v5, and a total of 10 points M. As described, 10 drying steps were performed. At the end of each drying step, the evaluation of the touch feeling of the entire garment 55 was performed with respect to the

evaluation items

1 and 2, “just good warmth” and “good touch”.

The inventor determined a reference point based on the evaluation results (evaluation points) of the

evaluation items

1 and 2 when each subject touches the entire clothing 55 that has finished each drying step. Specifically, out of the above 10 points, the point with the highest total score for each evaluation content of “exactness of warmth” and “excellent touch” of

evaluation items

1 and 2 is extracted, and this is used as a reference Points. According to this experiment, the extracted reference point was point M (1.03, 50 ° C.) in FIG.

(results of the experiment)
FIG. 21 is a diagram illustrating a comparison result of the subjective evaluation of the subject by the experiment for the eighth embodiment. In FIG. 21, the result of comparing the subjective evaluation of the tactile sensation between the reference point M and the four points P to S of Examples 1 to 4, and 5 of the reference point M and the points v1 to v5 of Comparative Examples 1 to 5 are shown. The result of contrasting subjective evaluation with points is shown. When the significance level is 5% and there is no significant difference with respect to the reference point M, that is, the point with a high evaluation score is “X1”, the significance probability is less than 10% and the score is lower than the reference point M and tends to be different Is “X2”, the significance level is 5% or less, the score is lower than the reference point M, and there is a significant difference as “X3”.

As a result, when the drying of the entire garment 55 is finished at the points P to S of Examples 1 to 4, the evaluation contents of “exactness of warmth” and “excellent touch” are used as criteria. No significant difference was observed with point M, and the evaluation was high. In the points v1 to v5 of Comparative Examples 1 to 5, the score was lower than that of the reference point M, and there was a tendency for a difference in the score difference or a significant difference. Therefore, a high evaluation was not obtained. From the result of such an experiment, the inventor makes a combination (K, T) of the target dryness and the target temperature in the region surrounded by the points P to S in FIG. 18 (shaded area in FIG. 18). It was found that if the finish of the entire garment 55 is set, the subjective feeling of the user is improved with respect to “just good warmth” and “good touch”, that is, an appropriate finish state can be obtained. Further, according to FIG. 21, it was found that the critical significance regarding the value of the region surrounded by the points P to S is also shown.

(Experiment for Embodiment 9)
In the experiment, the clothes 55 including six towels having the size shown in the ninth embodiment was dried in the washing / drying machine 1000. 10 combinations of temperature and dryness (K1, T1) at four points A to D in FIG. 19, 5 points indicated by points v6 to v10, and a total of 10 points N are detected. A drying step was performed. At the end of each drying process, the subject touches the towel extracted from the dried clothes 55, and the “warmth just”, “feel soft”, “soft” and “dry” shown in Evaluation Items 1 to 5 in FIG. Subjective evaluation of subjects was performed for each evaluation content of “feel” and “softness”. As a result, for all the evaluation contents in FIG. 20, the reference point was the point with the highest total score of the average scores. The reference point was point N (1.06, 50 ° C.) in FIG.

(results of the experiment)
FIG. 22 is a diagram showing the result of comparison of the subjective evaluation of the subject by the experiment for the ninth embodiment. It is a figure which shows the result of subjective evaluation. In FIG. 22, the result of contrasting the subjective evaluation of the tactile comfort between the reference point N and the four points A to D of Examples 5 to 8, and the reference point N and the points v7 to v11 of Comparative Examples 6 to 10 are shown. The result of comparing the subjective evaluation of touch feeling with 5 points is shown. When the significance level is 5% and there is no significant difference with respect to the reference point N, that is, the point with a high score is “X1”, the significance probability is less than 10% and the score is lower than the reference point N and tends to be different. “X2”, the case where the significance level is 5% or less and the score is lower than the reference point N and there is a significant difference is indicated by “X3”.

As a result, when the drying of the towel included in the clothing 55 is finished at four points A to D in Examples 5 to 8, there is no significant difference from the reference point N for each evaluation content shown in FIG. We were not seen and became high evaluation. In the points v6 to v10 of Comparative Examples 6 to 10, the score was lower than that of the reference point N, and there was a tendency for a difference in the score difference or a significant difference. Therefore, a high evaluation was not obtained. From the result of such an experiment, the inventor applied to the garment 55 so that the combination (K1, T1) of the target dryness and the target temperature within the region surrounded by the points A to D (shaded area in FIG. 19) is obtained. When the finish of the towel included was set, the user's subjective feeling was improved for all the evaluation items shown in FIG. 20, that is, the towel was found to have an appropriate finish. Further, according to FIG. 22, it was found that the critical significance regarding the value of the region surrounded by the points A to D is also shown.

In each of the eighth to tenth embodiments, laundry such as clothing 55 is taken as an example of the object to be dried, but bedding such as a futon may be used. In addition, the drum-type washing / drying machine 1000 has been exemplified as an apparatus having a drying function. However, a vertical washing / drying machine may be used, and a drying machine (a large-scale drying machine or a futon used in a household drying machine or a coin laundry) may be used. Drying machine).

(Configuration of Embodiments 8 to 10)
The electric device (washing and drying machine 1000) includes a control unit (CPU 23) for controlling the electric device, a tank (drum 3) for storing an object to be dried (55), and heating and drying gas. Hot air supply unit (air path 6, heater unit 8, heat pump unit 7) for blowing the heated and dried gas into the tank through the air supply port, and gas sent from the tank through the exhaust port A humidity detector 602 that detects the humidity of the gas, and a temperature detector 601 that detects the temperature of the gas sent from the tank through the exhaust port. The controller is configured such that the humidity detected by the humidity detector after the start of gas heating and drying by the hot air supply unit is a predetermined humidity, and the temperature detected by the temperature detector is a predetermined temperature. Then, the hot air supply unit is controlled to stop heating and drying.

Thus, heating and drying can be stopped when the finished state of the object to be dried is such that a predetermined humidity and temperature are detected for the gas delivered through the exhaust port. Therefore, the finished state of the object to be dried is prevented from being in a state that does not satisfy the predetermined humidity and temperature conditions (for example, the object to be dried is insufficiently dried (moist), overdried, high temperature). Can do.

The above-mentioned predetermined humidity and temperature are sent out from the tank through the exhaust port when the dryness of the object to be dried in the tank is the target dryness and the temperature of the object to be dried is the target temperature. Each of the humidity and temperature of the gas being produced.

Thereby, when the dryness of the material to be dried reaches the target dryness and the temperature reaches the target temperature, the heating into the tank and the blowing of the dried warm air can be stopped. Therefore, it is possible to prevent the object to be dried from being excessively dried or from becoming high temperature.

The target dryness K satisfies the condition (1.01 / D ≦ K / D ≦ 1.05 / D), and the target temperature T satisfies the condition (45 ° C. ≦ T ≦ 60 ° C.). D represents a coefficient determined by the material of the material to be dried, W represents the weight of the material to be dried in a completely dry state, and W1 represents the weight when the dryness of the material to be dried is the target dryness The target dryness K is expressed by K = (DW / W1).

Therefore, by defining a region with a certain degree of drying and a certain temperature for the material to be dried after drying, the feeling of over-drying is eliminated (that is, the material is dried in a state containing an appropriate amount of water). Can be maintained). Further, by defining the temperature in a certain region, it is possible to provide the user with a good finish due to the warm feeling of the object to be dried. By defining such areas of dryness and temperature, satisfaction with the finish of drying can be enhanced. Specifically, with such a configuration, the satisfaction of the user can be improved in the touch comfort of “just good warmth” and “good touch” in the dried object after drying.

The above target dryness and target temperature indicate the target dryness and target dryness of the towel, respectively. When the object to be dried includes a towel in a ratio of approximately 13% to 30% with respect to the total weight of the object to be dried, a combination of the target drying degree K1 of the towel and the target temperature T1 of the towel (K1, T1) Are point A (1.045, 45 ° C.), point B (1.045, 50 ° C.) in a coordinate system determined by the coordinate axis of the target dryness K1 and the coordinate axis of the target temperature T1 of the towel orthogonal to the coordinate axis, The coordinates (shaded area in FIG. 19) in the region surrounded by the point C (1.075, 65 ° C.) and the point D (1.075, 45 ° C.) are shown.

Therefore, in the finished state after drying of the towel contained in the material to be dried, it is possible to achieve a finished state that achieves the target dryness and the target temperature.

The hot air supply unit includes a gas flow path (6) and a heating / drying section (7, 8) provided in the flow path for heating and drying the gas in the flow path. One end of the channel is connected to the air supply port, and the other end of the channel is connected to the exhaust port.

Therefore, a gas circulation path that connects the flow path, the heating and drying unit, and the inside of the tank is formed, and the heated and dried gas can be supplied into the tank while circulating the gas through the circulation path.

The humidity detection unit and the temperature detection unit are arranged on the exhaust port side in the flow path. Therefore, by detecting the humidity and temperature on the side closer to the inside of the tank in the flow path, it is possible to measure the humidity and temperature in the tank (more specifically, the inside of the tank containing the material to be dried). It becomes possible. As a result, it is possible to more accurately determine whether or not to stop the hot air supply unit.

The above heating and drying unit has a heat pump unit (heat pump unit 7) and a heating device (heater unit 8). Therefore, it becomes possible to send a drier gas into the tank (hot air supply).
