Description

Dryer with liquid material injection means {DRYER WITH FLUID INJECTION MEANS}

The present invention relates to a dryer having a liquid substance spraying means, and more particularly, to a dryer having a liquid substance spraying means having a spraying means for spraying a liquid substance such as steam or the like on a garment during a drying process of the garment dryer for drying the garment. It is about.

Clothing processing apparatuses such as a clothes dryer or a washing machine having a drying function accommodate clothes in a drum installed inside the main body, and then supply hot air into the drum to dry the clothes. In this process, since the dehydrated clothes are placed in the drum as they are, the hot hot air removes the moisture of the clothes. Therefore, the clothes tangled with each other are dried and wrinkles are generated.

In order to solve this problem, there has been proposed a type of dryer which can eliminate wrinkles by supplying steam to clothes after drying is completed. According to the dryer having such a steam supply device, the steam may be supplied during drying so that the clothes contain an appropriate amount of moisture to remove excessive wrinkles and to be in a state suitable for ironing the clothes taken out of the dryer. Can be.

The steam supply device as described above is supplied with liquid, typically water, from a liquid reservoir installed on one side of the dryer, usually adjacent to the top plate, and heated by a heating means to generate steam, and then into a drum. It will include a steam generator to inject. Therefore, the addition of a steam generator for generating hot steam increases the number of parts and requires a separate power for generating steam.

In addition, the steam generated in the steam generator is injected to the drum through the hose, etc. When the length of the hose is long, the steam is condensed inside the hose due to the temperature decrease, and the desired amount of steam is not obtained, It may be introduced into the drum and cause a decrease in the dryness of clothes.

On the other hand, since the clothing after drying is dried to an appropriate level or more, the fabric may be excessively stiff or prone to static electricity. To prevent this, the clothing after drying is softened by spraying water in a state of atomization to soften the clothing, and There are cases where it can be prevented from occurring. In addition, in order to give a specific scent to the dried clothes, a mixture of the fragrance stock solution and water may be sprayed onto the clothes. For this purpose, a separate liquid injection means must be included in addition to the steam generator, which complicates the structure of the device. there is a problem.

In addition, the injection means may further include a valve for regulating the movement of the fluid in the respective conduit.

Here, the liquid substance may be water, in addition, may be a mixture of water and the fragrance stock solution. Here, the fragrance undiluted solution means a substance that can give a specific fragrance to clothes.

In addition, the first atomization nozzle may spray the atomized liquid material upstream or downstream of the heater on the hot air supply passage. When the liquid substance is injected upstream of the heater, it is heated while passing through the heater, thereby further increasing the amount of steam generated, and when sprayed on the downstream side, there is a possibility of deterioration while passing through the heater. Even when mixed) to maintain the original character of the material.

In the above aspect, the liquid substance is not directly injected into the hot air supply passage, but is injected into the injection chamber and flows into the hot air supply passage. The injection chamber means a separate place separate from the hot air supply passage.

Here, the spraying means may include first and second atomization means installed in the spray chamber and the washing tank, respectively; And pumping means for pumping the liquid material to the atomization means, wherein the first and second atomization means may be first and second atomization nozzles.

In addition, the liquid substance may be a mixture of water or a stock solution with water.

In addition, the injection chamber may be communicated with the downstream of the heater on the hot air supply passage, and vice versa.

In addition, the injection port of the first atomization nozzle may be positioned to protrude into the injection chamber.

Here, a screen for blocking a droplet of a predetermined size or more may be installed in the communication portion between the spray chamber and the hot air supply passage. Through this, the liquid which is not sufficiently atomized can be prevented from remaining inside the hot air supply passage. Here, the screen may be made of a mesh.

According to the aspects of the present invention having the configuration as described above, it is possible to supply the steam inside the drum without a separate steam generator, thereby reducing the number of parts, it is possible to obtain the effect of reducing the manufacturing cost and improving assembly performance, vaporization The condensed liquid can be prevented from condensing again.

In addition, the injection means having two conduits branching from one reservoir can selectively supply steam and atomized liquid, thereby further simplifying the structure.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the dryer according to the present invention.

1, an embodiment of a dryer according to the present invention is shown. The dryer 100 includes a cabinet 102 constituting an external appearance of the apparatus, and a clothes inlet 104 is formed on a front surface of the cabinet 102 for injecting clothes to be dried into the cabinet 102. . The clothes inlet 104 is opened and closed by a door 106, and an operation panel 108 is disposed above the clothes inlet 104 to arrange various operation buttons for operating the dryer.

Meanwhile, a drawer cover 110 is provided at one side of the operation panel 108, and a cartridge to be described later is mounted inside the drawer cover 110. The cartridge has a liquid to be sprayed on the drum, specifically, water is stored therein, and the drawer cover 110 can be pulled out by the user by hand to replace the cartridge or replenish water therein. Of course, water is not necessarily stored inside the cartridge, and a mixed liquid of water and the fragrance stock solution may be stored. In this case, the fragrant steam can be injected into the drum, and the fragrance can be applied to the garment more efficiently as the fragrance can be delivered to the garment at a high temperature where the movement of the gas is more active as well as to prevent wrinkles caused by the steam injection. Will be.

2 is a cross-sectional view schematically showing the internal structure of the dryer 100, a cylindrical drum 120 is rotatably mounted inside the cabinet 102, the front lower side of the drum 120 An air suction path 130 communicating with the drum 120 is formed. The air suction path 130 corresponds to a passage through which the internal air of the drum 120 is sucked and moved by the blower 134 which will be described later, and the sucked air is along the air path (not shown). To the side. In addition, the outside air introduced through the outside air inlet 132 formed on one side of the cabinet 102 is also moved to the blower 134 to exchange heat with the inside air of the drum 120.

The driving motor 136 is disposed at the rear side of the blower 134 and the blowing fan 140 is positioned at the driving shaft 138 of the driving motor 136. The blowing air 140 pumps heat-exchanged air into the inside of the hot air supply path 150 installed at the rear of the cabinet 102. The compressed air is heated by the heater 152 installed inside the hot air supply path 150 while passing through the hot air supply path 150, and then is supplied again into the drum 120.

The supplied hot air contacts the clothes introduced into the drum 120 to dry the clothes, and then circulates inside the drum while moving to the blower 134 through the air suction path 130.

Now, with reference to FIGS. 3 and 4 will be described with respect to the liquid material injection device of the dryer (100). A drawer 112 is mounted on a rear surface of the drawer cover 110, and the drawer 112 is configured to move together with the drawer cover 110, and accommodates a cartridge 160 therein. have. The cartridge 160 is a hollow container and stores liquid such as water therein through an injection hole 162 formed on an upper surface thereof.

On the other hand, the cartridge 160 is coupled to the injection pump 170 through a check valve (not shown), etc., the liquid stored in the cartridge 160 is injected at a high pressure by the injection pump 170 It is moved along the connecting hose 172.

The connection hose 172 is branched into two paths, one side 172a of the hot air supply path 150 is fixed to the back plate 182 of the tub 180 to rotatably support the drum 120. It is connected to the first atomization nozzle 174 is installed on the upper side, the other side is connected to the second atomization nozzle 175 is installed on the back plate 182. Through this, the liquid stored in the cartridge 160 is sprayed into the hot air supply path 150 or the drum 120 in an atomized state.

The liquid in the atomized state sprayed into the hot air supply passage 150 by the first atomization nozzle 174 is heated at a high temperature (about 200 to 300 ° C.) by a heater located inside the hot air supply passage 150. Heat exchanged in contact with the hot air of the), thereby vaporized and flows into the drum along the hot air. Since the atomized liquid comes into contact with the hot air by atomization, the contact area is widened and rapidly vaporized so that the injected liquid cannot be vaporized and does not remain inside the hot air supply passage. In addition, a separate steam generator is also unnecessary.

On the other hand, the liquid in the atomized state injected directly into the drum 120 by the second atomizing nozzle 175 is applied to the clothes accommodated inside the drum 120 in the atomized state. The atomized liquid sprayed in this way lowers the dryness of the finished clothing and softens the clothing to an appropriate level, and at the same time prevents the generation of static electricity.

In the above example, the first atomization nozzle 174 is located upstream of the heater, but is not necessarily limited thereto. An example of a location located downstream of the heater may be considered. In this case, since the atomized liquid is directly heated by the heater, more rapid vaporization can be achieved.

Now, the operation of the above embodiment will be described. The drying object introduced into the drum 120 by the user is removed with moisture by the hot air supplied through the hot air supply path 150. Then, after a predetermined time has elapsed, drying is completed while all the moisture contained in the clothing is evaporated, and after the drying is completed or just before the completion, the water is atomized in the hot air supply passage (1). 150) When sprayed inside, it is vaporized by high temperature hot air and comes into contact with clothes. Through this, wrinkles and the like of clothing can be eliminated and an unpleasant smell can be removed.

On the other hand, in the case of directly spraying the liquid in the atomized state instead of the vaporized liquid, when the liquid is supplied through the second atomization nozzle 175, the liquid in the atomized state is sprayed while the effects of softening and antistatic of clothing Can be obtained. At this time, some of the liquid is vaporized due to the high temperature atmosphere inside the drum 120 may also be effective to spray steam and liquid at the same time. In some cases, the liquid may be simultaneously supplied through the first and second atomization nozzles 174 and 175 to simultaneously spray the vaporized liquid and the atomized liquid onto the garment.

In addition, in the above example, the atomized liquid is directly injected into the hot air supply path, but the present invention is not limited thereto, and an example in which a separate injection chamber is provided in the hot air supply path 150 may be considered.

Referring to FIG. 5, an example in which an injection chamber 190 is formed to protrude on one side of the rear surface of the hot air supply path 150 ′ and a first atomizing nozzle 174 is installed on the injection chamber 190 is illustrated. It is. The spray chamber 190 is a separate space separate from the hot air supply path 150 ′ and provides a space in which the liquid sprayed in the atomized state through the first atomizing nozzle 174 is temporarily located. The atomized liquid staying within the fact 190 is moved into the drum through the screen 192 made of mesh by the pressure of the hot air flowing in the hot air supply passage 150 '.

Therefore, if the size of the droplets is too large, the droplets do not flow along the hot air and remain on the bottom surface of the spray chamber 190 so that the sprayed liquid does not vaporize and fall below the hot air supply or directly contact the clothes. . This blocking effect is further enhanced by the screen 192.
