Description

TECHNICAL FOR OPERATING OF CLOTHES TREATMENT APPARATUS HAVING FRAGRANCE SUPPLYING MODULE}

The present invention relates to a method for controlling a clothes treating apparatus having a means for injecting incense into a drum, and more particularly, to inject incense into a drum of a clothes treating apparatus having an incense supply module to effectively deposit the incense on clothes. It relates to a fragrance injection control method for.

In general, a laundry treatment apparatus includes a washing machine and a clothes dryer or a laundry dryer having a function of washing and drying. A washing machine is a device that removes contaminants from contaminated laundry while undergoing washing, rinsing, and dehydration. And a storage tank installed inside the main body and storing the water and a rotating tank rotatably installed in the storage tank. The laundry is put in the rotating tub with detergent and the rotating tub is rotated to apply physical impact to the laundry to wash the laundry. In addition, a washing machine is generally divided into two types according to whether the rotating shaft of the rotating tub for processing laundry is vertical or horizontal. The washing machine in the case where the rotating shaft is vertical is called a top load washing machine and the rotating shaft is called a drum washing machine. .

In addition, the clothes dryer is a device for drying laundry by putting laundry in a state where the washing is completed and the dehydration process is completed into the drum of the dryer, and supplying hot air into the drum to evaporate the moisture of the laundry. In the construction of the dryer, the dryer includes a drum inside the dryer into which laundry is put, a driving motor for driving the drum, a blowing fan for blowing air into the drum, and a heating means for heating the air introduced into the drum. Is done. The heating means may use high temperature electrical resistance heat generated by using electrical resistance, or combustion heat generated by burning gas.

Then, the dryer is the air exiting the drum will have the moisture of the laundry inside the drum to become air of high temperature and high humidity. At this time, the dryer can be classified according to the method of treating the high temperature and high humidity air, and the hot and humid air is circulated without being discharged to the outside of the dryer to allow heat exchange with the outside air in the condenser so that the moisture contained in the high temperature and high humidity air. It is divided into a condensation type dryer for condensing and an exhaust type dryer for directly discharging the air of a high temperature and high humidity passing through the drum to the outside.

By the way, when the laundry after the washing is completed in the washing machine is put into the dryer and dried, the moisture contained in the dry is removed to dry the process, but the dried clothing smells of washing water or detergent or before washing If the smell, etc. buried in is not completely gone and remains even after the completion of drying there was an inconvenience causing uncomfortable to the user. Therefore, the scent was fed inside the drum to remove this odor and to make the user feel refreshed.

However, in the conventional method of supplying the fragrance, the nonwoven fabric in which the fragrance substance is adhered is put together with the dried product in the dryer drum to remove the smell of detergent and wash water remaining in the dried product and add new fragrance. However, this conventional technology has various problems, and the nonwoven component used is not completely decomposed, causing the nonwoven fabric to move the dryer drum together with the dry matter, causing mechanical obstacles such as blocking the filter. Due to phosphorus contact, the fragrance addition performance was also degraded. In addition, it is difficult to reprocess the nonwoven fabric after use, causing environmental problems such as waste generation, and since the nonwoven fabric is put in the initial stage of the drying process, there is a problem that sufficient fragrance does not remain in the dry matter after the drying administration is completed. Was induced.

In addition, the conventional fragrance supplying method is to store the fragrance material in the solid form inside the dryer and, if necessary, to emit the fragrance by heating or applying vibration and to provide the fragrance supply duct to the drum of the dryer. The method was also used. However, such a solid type incense supply means has difficulty in supplying sufficient aroma to the drum, and also lacks the ability to timely spray the drum to the required time.

In addition, although the incense was injected into the drum to supply the incense, the fragrance was not effectively deposited on the clothes inside the drum, and thus sprayed more than necessary to waste the fragrance liquid stored in the dryer, or to control the incense injection module. There was a problem such as an improper method affecting the life of the fragrance supplying device.

In order to solve the above problems, the present invention is provided with a fragrance supply module that can effectively inject the fragrance into the dryer drum, while injecting the fragrance into the drum of the dryer in the fragrance supply module while maintaining the reliability and durability, etc. An object of the present invention is to provide a fragrance spraying method so that fragrance can be effectively deposited on clothing.

Hereinafter, a method of supplying incense into the drum of the dryer by using the incense supply module described above will be described.

The fragrance injection method according to the present invention for controlling the fragrance supply module to inject fragrance into the dryer drum is divided into (1) pretreatment step, (2) fragrance step and (3) post-treatment step.

This will be described below schematically.

(1) The pretreatment step is a process that makes the fragrance fresh and swells so that the fragrance can be doubled to the fabric. Supplying the fragrance to the drum in the dryer according to the present invention relates to spraying the fragrance after drying the laundry and the dehydration of the laundry in the dryer, but is not necessarily limited to the user to take out the clothes stored in the closet for a long time It is also possible to carry out the fragrance feeding process according to the invention before using the garment. This is because clothing stored in long-term intestines may be wrinkled or wrinkled during storage, or may have an intestinal odor. In this case, when the pretreatment step is performed before supplying the incense, the cloth of the garment is inflated, and thus, the incense may be better deposited in the incense treatment step.

In addition, in the pretreatment step, the hot air heated by the heater may be supplied to the drum, and when the hot air is supplied, the texture of the cloth may be more flexible, and the fresh effect may be better. In the case of this hot air supply, a cooling process is required to lower the temperature inside the drum just before entering the fragrance treatment step. This is because when the fragrance is sprayed onto the fabric in the drum or in the state where the temperature of the cloth is high, the fragrance of the fragrance deposited on the cloth is lowered because the fragrance is not deposited on the cloth and evaporates away.

(2) The fragrance treatment step is a process of pumping the fragrance liquid stored in the fragrance supply module described above and spraying the fragrance liquid into the drum through the nozzle to cut the fragrance on the cloth. In the fragrance supply module described above, an example in which the fragrance liquid is pressurized to a constant pressure using a pump in a storage tank or a chamber in which the fragrance liquid is stored is injected into the drum through a nozzle. However, according to the embodiment, the fragrance liquid is not pumped by the pump. The fragrance may be supplied into the drum by opening the supply passage through which the fragrance is supplied, or a separate evaporation unit may be configured to evaporate the fragrance liquid to supply the inside of the drum so that the fragrance is better evaporated from the fragrance liquid. In this case, the evaporation unit may be installed at various positions such as the front supporter, the rear supporter, or the inside of the duct into which the fragrance is introduced.

(3) In the post-treatment step, the fragrance sprayed by the drum is distributed evenly on the clothes, and is carried out to evenly dry the clothes, and the post-treatment steps include a cooling process, a drying process, and a recooling process. The cooling process is a process in which the fragrance sprayed inside the drum is easily transferred between the fabrics, and the drying process is a process in which the fragrance sprayed to the drum is dried in the fragrance treatment step. This is a process to allow the user to take out the clothing. However, in the refresh administration, there may be no cooling during the initial fragrance injection, which will be described later.

Hereinafter, the (1) pretreatment step, (2) flavor treatment step and (3) the post-treatment step will be described in detail.

(1) pretreatment step

The basic method of the pretreatment step is to first tumble the drum (rotating the drum at a constant speed by the drive means), which may be performed in one or two directions. The cloth accommodated in the drum by the tumble goes through a process of rising and falling with the drum, and through this process, the cloth is inflated and foreign matters that may be stuck to the cloth are removed and are thus fresh.

In addition, the time during which the tumble is performed in the pretreatment step is preferably longer than the time required in the fragrance treatment step in order to fully exhibit the effect of the pretreatment step. According to the experiment, the tumble time is about 4 to 5 minutes. Is suitable.

In addition, air may be supplied to the drum during the tumble, which is performed by operating a blower fan provided in the dryer. This is because if the air is circulated by the blower fan to the drum in the tumble process, the abnormal odor remaining between the cloths can be removed, and the air can pass between the cloths, making it easier to penetrate the fragrance material.

In this case, the air supplied to the drum may be hot air heated by a heater, and when the hot air is supplied, the tissue of the cloth becomes more flexible and the fresh effect may be better. If hot air is supplied, the process of lowering the temperature inside the drum immediately before entering the fragrance treatment step is necessary. This means that when the fragrance is sprayed onto the cloth while the drum or the cloth temperature is high, the fragrance is not deposited on the fabric. This is because the strength of the fragrance deposited on the fabric is reduced because it evaporates and flies away.

 As such, in the step of injecting the fragrance, it is necessary to recognize the temperature inside the drum, and the temperature may be based on the temperature of a specific point inside the drum or by measuring the temperature of the cloth tumbling in the drum. For example, the temperature of the air discharged from the dryer drum may be measured.

 The intensity of the user's feeling of the fragrance deposited on the clothes from the drum is subjective, but experiments show that the degree to which the user feels the intensity of the fragrance is stronger when the temperature inside the drum is lower when the fragrance is sprayed onto the clothes. Got it. In a typical dryer drying process, a cooling process is performed to supply unheated air after finishing drying to remove the laundry from the drum, thereby lowering the temperature of the laundry so that the consumer taking out the laundry does not feel hot. In addition, when the user looks at the temperature at which the user takes out the laundry on the basis of the drum exit temperature, it was found that the intensity of incense felt by the consumer at about 47 degrees is much weaker than that of the consumer at about 30 degrees.

Referring to FIG. 8, the contents are shown in a graph. In the graph, the horizontal axis represents the temperature of the drum at the time when the fragrance is injected into the drum, and the vertical axis represents the magnitude of the intensity of the scent felt by the consumer. In this embodiment, the temperature was measured based on the outlet temperature of the drum. However, the present invention is not necessarily limited thereto, and the temperature of the drum may be measured at other parts of the drum, and the temperature measured at other parts of the drum may be compared with the intensity of the fragrance at this time. However, when the temperature is measured at other parts of the drum, there may be a slight difference in terms of specific values from the graph of FIG. 8, but the shape of the general graph is the same.

In this way, the user can feel the fragrance from the cloth, the temperature at the time when the fragrance is injected into the drum is approximately from the temperature of about 40 degrees or less in the drum, and when the temperature is 20 degrees or less, the intensity of the fragrance is too strong to the user. Therefore, it was found that the strength is sufficient to cause rejection. Thus, the optimum temperature for treating fragrance is between about 40 degrees and 20 degrees. Here, the user will want to process the fabric within a short time, and, in consideration of this, when the temperature inside the drum is between about 35 degrees and 25 degrees, it can be controlled to have a suitable fragrance intensity within a suitable time. Most preferably, the optimum results were obtained in terms of time and fragrance strength when the drum temperature was controlled at about 30 degrees at the time of fragrance injection. Here, the internal temperature of the drum was based on the drum outlet temperature, but the temperature of the drum may be used by measuring the temperature of another point inside the drum instead of the outlet temperature. However, when using the temperature of the other point of the drum may be somewhat different from the outlet temperature of the drum, and according to the experiment there was a difference of about 30 degrees around.

The fragrance intensity, which is the intensity that the user feels when the fragrance is deposited on the fabric, can be variously determined according to the user's needs.The dryer control panel is provided with a select button so that the user can select a desired intensity through the key input unit. In order to control the fragrance intensity corresponding to the button selected by the user, the dryer controller may control the temperature inside the drum to be different. For example, after the user selects a course that can run the fragrance treatment, the desired intensity is set through the fragrance intensity control unit that can select the intensity of the fragrance, and when the operation button of the dryer is pressed, the control unit controls the intensity of the fragrance selected by the user. (Eg strong, medium, weak) and control the temperature inside the drum according to the selected fragrance intensity. To do this, the control unit reads the temperature value of the temperature sensor (here, the drum outlet temperature sensor) and sets the fragrance spray pump or the shut-off valve for the set time when the drum outlet temperature is 25 degrees when the intensity of the fragrance control unit selected by the user is 'strong'. Operating to spray or evaporate the fragrance material in the drum to treat the fragrance on the fabric. In the same way, when the intensity of the user-selected fragrance control unit is 'medium', when the outlet temperature of the drum is 30 degrees, and when the intensity of the user-selected fragrance control unit is 'weak' the fragrance when the outlet temperature of the drum is 35 degrees. The injection pump or on / off valve is operated for a set period of time to treat the fragrance of the fabric in the drum.

At this time, instead of the temperature value, it is possible to control by setting a cooling time (time for supplying air not heated by the heater) corresponding to the heading intensity. In addition, the fragrance intensity can be adjusted by varying the fragrance injection time, which will be described in detail in the next fragrance treatment step.

(2) fragrance treatment step

The feature of the fragrance treatment step is that the drum is tumbled while injecting fragrance from the fragrance supply module into the drum for a predetermined time. In addition, the injection amount of the fragrance injected into the drum is determined by the mass flow of the injected fragrance liquid or the operation time of the pump or the opening time of the opening / closing valve, and the like. The injection amount of the fragrance will be determined according to the intensity of the fragrance selected by the user. In other words, the stronger the intensity of the fragrance control unit selected by the user, the longer the fragrance is injected by controlling the pump operation time and the like, thereby adjusting the injection amount. Hereinafter, various embodiments of the flavor treatment step according to the present invention will be described.

1) First embodiment

In the first embodiment, continuous spraying and interrupted spraying will be described in the method of spraying incense to the drum.

In the present embodiment, continuous injection is a case where the incense is injected from the incense supply module to the drum is continuously injected, intermittent injection is intermittently sprayed to the drum by repeatedly turning on or off the pump or on-off valve of the incense supply module If it is. Such continuous injection and intermittent injection are distinguished according to the amount of laundry to be put into the drum. When the controller of the dryer detects the quantity of water injected into the drum and determines that the quantity is small, continuous spraying is performed. When the quantity of detected quantity of the controller is determined to be large, intermittent spraying is performed.

Specifically, in the present embodiment, the process of processing fragrance may include a case in which the user selects a fragrance treatment operation and a general dry operation including a fragrance injection process. If the user selects the perfume treatment operation, selecting the perfume treatment operation; Detecting a quantity of quantity by the dryer control unit; Performing intermittent injection when the quantity detected in the quantity detection step is large; If the quantity detected in the quantity detection step is small, the step of performing a continuous injection; comprises. At this time, in the intermittent injection step, the fragrance is sprayed to the drum while repeating the on / off time for a predetermined time according to the detected quantity.

In Fig. 9, the steps of a general dry operation including a fragrance injection process are shown. Looking at the above process, the pretreatment step; Fragrance treatment step; And then proceeds to the post-treatment step, in the fragrance processing step is to inject the fragrance to the drum again in the fragrance processing step, in this case, if the quantity detected by the control unit is large, the intermittent injection is carried out, If the detected quantity is small, continuous injection is performed. In intermittent injection, the fragrance is sprayed while the on / off is repeated for a predetermined time according to the detected quantity. In addition, the time for spraying the fragrance (continuous spray or intermittent spray) may be determined based on the intensity or quantity of the fragrance selected by the user, or may be determined in consideration of both.

The reason why the fragrance is intermittently sprayed when the quantity is large is that, when the quantity is small, the sprayed fragrance can easily be uniformly deposited on the fabric. Because it can. Therefore, in the case of a large amount of incense, the fragrance may be effectively deposited on the fabric by injecting the fragrance from the fragrance supply module to the drum for a predetermined time and then tumbling the drum to mix the cloth with each other, and then spraying the cloth again. Through this process, the fragrance is uniformly deposited on the fabric, thereby improving the uniformity of the fragrance. Several factors that cause the fragrance of the drum to be uniformly deposited will be described in detail below. Uniformity generally shows good results when the number of times the fragrance is injected is about 3 to 4 times regardless of the amount of the dose.

According to the experiment, it is preferable to perform continuous spraying when the amount is 1 to 2 kg, and to perform intermittent spraying when the weight is 3 kg or more. And, in the case of intermittent injection, the intermittent interval, that is, the time when the pump is turned off, is the time taken for the cloth to rotate in the drum as the drum rotates (that is, the cloth falls along the drum and then falls, causing the cloth to loosen or blend. Time to process), this time is preferably about 5 seconds. In addition, the time when the pump of the fragrance supply module is turned on in the intermittent injection is preferably set to be the same or greater than the last on time. The reason that the on time of the last stage of the on / off stroke is longer than the on time of the intermediate stage is that, when the duration of the last stage is longer, the amount of the fragrance component injected into the fabric is the highest, so that the fragrance is applied to the cloth for a long time. It may remain. For example, if the volume is 3 kg, the time when the pump of the fragrance supply module is turned on / off during the intermittent injection process when the user selects the intensity of the fragrance as 'medium' is 15 seconds on, 5 seconds off, 15 The process proceeds from seconds on, 5 seconds off and 20 seconds on.

2) Second embodiment

The second embodiment relates not to a drying course performed after washing and dehydrating, but to a case of treating clothes in use or being stored in a short time, and the touch-up process mentioned above. At this time, a separate quantity detection is unnecessary, and the fragrance spraying has a continuous spraying process. The reason why the quantity detection is unnecessary here is that the original purpose of the touch-up Koso is to omit a small amount of load so that a separate quantity detection step is omitted.

10 to 11 illustrate the progress of the touch-up process according to the present embodiment, which includes selecting a touch-up process; Cooling step; And a fragrance spraying step (see FIG. 10). However, a hot air supply and tumble step of supplying hot air to the drum and performing tumble before the cooling step may be added (see FIG. 11). In this case, the cooling step is performed just before the fragrance spraying step so that the fragrance is well deposited on the fabric, and the fragrance is sprayed continuously in the fragrance spraying step.

In another embodiment of the touch-up process, there may be a step in which the user selects the intensity of the fragrance. In this case, when the touch-up process is performed, selecting the touch-up process; Selecting a fragrance intensity; Cooling step; And it comprises a fragrance spraying step. In this case, the amount of incense is adjusted according to the intensity of the incense selected by the user. The amount of incense can be controlled by the operation time of the pump or the valve of the incense supply module.

3) Third embodiment

The third embodiment relates to a process of spraying fragrance on the clothes inside the drum to achieve the purpose of removing wrinkles or deodorizing clothes, and the fragrance refresh course mentioned above. The difference from the second embodiment is to add fragrance while deodorizing and removing wrinkles of clothes worn or stored for a long time.

12 shows a state in which a refresh process is performed according to an embodiment of the present invention. In this case, selecting the refresh process is performed. A first fragrance spraying step; Cooling step; It comprises a second fragrance spraying step. At this time, the fragrance spraying step is carried out by a continuous spraying process for continuously spraying the fragrance. In addition, the time in which the fragrance is injected in the first fragrance spraying step is set longer than the time in which the fragrance is sprayed in the second fragrance spraying step, which is sprayed with more fragrance in the first fragrance spraying step to remove wrinkles and deodorize the fabric. The effect is to achieve. Between the first fragrance spraying step and the second fragrance spraying step may further include a drying step of drying the cloth by supplying hot air, which is wetted by the fragrance sprayed onto the drum in the first fragrance spraying step. If it is there it is to dry.

Further, in another embodiment of the refresh process, the user may select the intensity of the scent, and when the refresh process is performed, selecting the refresh process; Selecting the intensity of the scent; A first fragrance spraying step; Cooling step; It comprises a second fragrance spraying step. When the user selects the intensity of the fragrance, the fragrance is injected by adjusting the fragrance injection amount according to the intensity of the selected fragrance. Incense injection amount is controlled by adjusting the operating time of the pump or valve of the incense supply module.

During the fragrance spraying step described above, the blower fan of the dryer may be continuously operated to supply air to the drum while rotating the drum, and the drum is rotated while the fragrance is sprayed, but air is supplied to the drum. The blower fan of the dryer may be turned off so as not to.

Inside the dryer, there is also a one-motor system, in which a drum drive motor that rotates the drum and a fan motor that rotates the blower fan is composed of the same motor, and a drum motor that rotates the drum and a fan motor that rotates the blower fan are separate. As described above, there may be a two-motor system that consists of two motors and is provided with two motors. In one motor system, the drum and the blower fan are driven by one motor, so when one rotates, the other one always rotates. In the two motor system, the drum and the blower fan can rotate independently.

Therefore, in the two-motor system, while the drum is being rotated while the fragrance is injected, the blowing fan is not operated so that the fragrance can be injected in the absence of air flow inside the drum, so that the fragrance can be more effectively deposited on the clothes.

(3) post-processing steps

In the post-treatment step, after the fragrance injection step of injecting the fragrance is completed, a cooling process for supplying air to the drum by operating the blower fan in a state in which the heater is turned off is performed for a predetermined time. This is to allow the fragrance component to be transferred to and adhere to the cloth without being evaporated from the cloth through the cooling step immediately after the fragrance spraying. Then, the drum is continuously tumbled so that the fragrance can be evenly applied to the cloth through the tumble.

In the post-treatment step, the drying process may further include a drying process in order to remove moisture that may remain in the fabric by the fragrance sprayed in the fragrance spraying step, and to give a comfortable feeling. Supply hot air to the inside. In addition, after the drying process is performed, the cooling process further includes a cooling process so that the user taking out the clothing does not feel hot. At this time, the temperature of the cooling process is higher than the temperature of the cooling process for the fragrance spraying in the fragrance treatment step. It is good to finish drying at the temperature of degree degree. The post-treatment step immediately after fragrance spraying should be shorter than the pretreatment step prior to the fragrance treatment because the fragrance evaporates if the process is too long.

In the above, a method of supplying incense using the incense supply module has been described. In the following, it is important that the fragrance is uniformly deposited on the cloth when the fragrance is injected after the cloth is put into the drum, which is called uniformity. Hereinafter, the elements affecting the uniformity will be schematically described with reference to the accompanying drawings.

Referring to FIG. 13, a drying process is generally performed, and shows the timing of the operation of the pump of the fragrance injection module and the operation of the heater provided in the dryer according to the passage of time. About 1 minute after the graph is started, the spraying of the incense by driving the pump of the incense supply module is a process for removing the reverberation that may be left in the incense supply process performed in the previous step.

In general, step 1 is a period having a slight rest period before spraying the incense after the drying process, step 2 is the process of injecting the incense to the drum by driving the pump of the incense injection module, step 3 Is a cooling period in which the drum is cooled for a predetermined time, step 4 is a process of drying a part of the injected fragrance by operating the heater again, and step 5 is a cooling process in which the consumer finally takes out the fabric and cools it. Since each of these steps has been described above, a detailed description thereof will be omitted. Here, the uniformity representing the degree to which the fragrance is uniformly sprayed onto the fabric will be described.

Referring to FIG. 14, a graph illustrating the effect of the cooling time performed in step 1 of FIG. 13 on the uniformity is shown. In the graph, the degree of uniformity when the strength of the fragrance is strong, normal, and weak, respectively, is tested, and the vertical axis shows uniformity. In the above experiment, the cooling time of Step 1 was performed for 0 minutes, 1 minute, 3 minutes, 5 minutes, and 10 minutes, respectively, and the temperature shown on the right side of the above execution time was measured by measuring the temperature inside the drum after the cooling time. will be. As shown in the graph, the uniformity is best when the temperature inside the drum is 31.5 degrees after cooling in Step 1. Therefore, for uniformity, the cooling time in step 1 needs to be set so that the drum temperature is cooled to about 30 degrees.

In Fig. 15, after intermittently injecting the fragrance in step 2, which is a process of injecting the fragrance in the fragrance injection module, the relationship between the number of intermittent injections and uniformity is graphically shown. In FIG. 15, the horizontal axis represents spray times for the incense to the drum, and the vertical axis represents uniformity. The experiment shows the relationship between the number of incense injections and the uniformity by varying the amount of clothing put into the drum, that is, the amount of clothes from 1 kg to 6 kg. In this case, if the quantity is about 1-2 kg, the uniformity is good even when the number of injections is one time. At this time, it may be proceeded by continuous injection. Since the uniformity shows a good result, it turns out that it is preferable to advance by intermittent injection when a quantity exceeds 2 kg.

In FIG. 16, the uniformity measured by changing the cooling time in step 3 to step 5 of FIG. 13 is shown. In the graph, the total cooling time (that is, the sum of the cooling time of step 3 and step 5) is set to 5 minutes, the total cooling time is allotted to steps 3 and 5, and uniformity is measured. The two numerical values indicated on the horizontal axis in the graph indicate the cooling time in Step 3 and Step 5, respectively, and the unit of time means minutes. That is, 3-2 means the case where the cooling is performed for 3 minutes in step 3 and the cooling for 2 minutes in step 5. The graph shows that the uniformity is better when the cooling time of step 3 is longer than the cooling time of step 5. This is because after the fragrance is injected in step 2, the fragrance injected in the process of being tumbled while being cooled in step 3 can be spread evenly on the cloth. According to the experiment, it is understood that the cooling time of step 3 and step 5 is preferably 4 minutes and 1 minute, respectively, and the drying time of step 4 is preferably 0.5 minute. That is, 4 minutes cooling, 0.5 minutes drying, 1 minute cooling is most preferable after interrupting the fragrance in step 3.
