The air outside the case is sucked into the suction passage 2 and heated by the heater 4 while the blowing fan 5 is operated. The heated hot air is supplied to the inside of the drum 1 for a predetermined time to dry the laundry, and the moist air evaporated from the laundry is exhausted to the exhaust passage 3.

On the other hand, a disposable dehumidifying agent using calcium chloride or the like is widely used as a dehumidifying agent used in a conventional wardrobe. Such a dehumidifying agent is generally discarded after a certain amount of moisture is absorbed and is dehumidified. These dehumidifiers may be difficult to identify precisely when to replace them. In addition, there was an inconvenience to replace with a new dehumidifying agent.

However, desiccants such as silica gel in chemical dehumidifiers can be reused at the level of several tens of times through regeneration. Such a dehumidifying agent can be easily regenerated by using hot air in the above-described exhaust dryer. Therefore, a dryer capable of regenerating such a desiccant has been studied.

Accordingly, it is an object of the present invention to provide a dryer capable of providing a mounting portion inside a dryer so that a regenerable dehumidifier can be regenerated stably, and a method of controlling the dryer.

The present invention can regenerate the regenerable dehumidification module reusably by removing moisture using hot air from a dryer.

2 is a schematic view showing an exhaust type clothes dryer 110 according to the present invention.

Referring to FIG. 1, the casing 110 includes a casing 110, a drum (not shown) disposed inside the casing 110 and capable of accommodating an object to be dried, a heater 110 disposed on a rear surface of the casing 110, A door 140 installed on the casing 110 and configured to open and close the opening of the drum, and a door 140 formed on the lower side of the opening of the drum (See FIG. 6A) formed so as to allow the air to escape from the drum, and at least one of the inlet duct and the exhaust section, and the moisture absorbing unit 20 (see FIG. 3) or the dehumidifying module 50, see FIG. 3). The moisture absorbing portion is made of a dehumidifying material so as to absorb moisture in the air, and discharges moisture that has been absorbed and is reusable Is formed, The module 50 (see FIG. 3) includes a fan unit 11 (see FIG. 3) for blowing air, a main body 30 (see FIG. 3) capable of having the moisture absorber, the moisture absorber, And a connecting portion 40 (see Fig. 3).

When the mounting portion 160 is located on the filter mounting portion (lower side with reference to the drawing) for removing foreign matter from the air that escapes from the inside of the drum, the dehumidification speed can be improved because the air is gathered. And, when the mounting portion is located at a position where the mounting portion can be observed at the door portion (upper side with reference to the drawing), the visibility of removing moisture from the user's position can be improved.

Further, when the mounting portion is provided on the filter mounting portion and the door side, there is an advantage that it is easy to attach and detach from the user's standpoint.

3 is a conceptual diagram showing the configurations of the dehumidifying module 50 according to the present invention.

(a) is a conceptual view showing a cross section of the dehumidification module 50. Fig. The dehumidification module 50 may include the fan section 10, the moisture absorption section 20, the main body section 30, and the connection section 40. (b) is a conceptual view showing a state in which the respective components of the dehumidification module 50 are separated, and (c) is a conceptual view showing a state just before each component of the dehumidification module 50 is coupled.

Referring to the drawings, the fan unit 10 may include a fan unit 11 configured to blow air toward one direction. The fan unit 11 can be rotated to form a forced flow. The direction of the flow may be formed from the outside of the main body portion 30 toward the pan portion 10, such as the direction A shown in the drawing.

The moisture absorption unit 20 is disposed in a direction opposite to the air blowing direction of the fan unit 11 and may be made of a dehumidifying material so as to absorb moisture in the air.

The main body 30 may have a space in which the moisture absorber 20 may be provided, and the outer surface may be formed in a mesh shape so that air can pass through. That is, the outer surface of the main body 30 may have a mesh structure so that the air can easily pass through. Also, the fan unit 10 and the connection unit 40 may include a lattice structure so that the flow of air can be easily passed.

The connecting portion 40 may be formed to fit into the pan portion 10 and the main body portion 30 so that the pan portion 10 and the main body portion 30 can be engaged with each other.

Preferably, when the dehumidification module 50 performs dehumidification in a clothes storage room or the like, the fan section 10 is operated in a connected state. When the humidifying dehumidifying module 50 is regenerated in the dryer, it is possible to regenerate the fan unit 10 in a coupled state or in a state in which the fan unit 10 is detached.

Further, the regeneration and reuse of the hygroscopic unit 20 may be repeated dozens of times, and the performance of the hygroscopic unit 20 may be deteriorated to require replacement. The dehumidifying module 50 is formed to be able to exchange the moisture absorbing portion 20 by separating the connecting portion 40 and the pan portion 10 from each other.

The moisture absorption unit 20 may be made of a reusable material by discharging moisture that has been absorbed. Therefore, the moisture absorbing unit 20 can discharge moisture that has been absorbed by the hot air of the dryer.

The moisture absorption portion 20 may be formed in a shape close to a rectangle. The hygroscopic portion may have a physical property capable of being folded. And can be inserted into the main body part 30 while being folded on the main body part 30.

The connection portion 40 may be formed of a cylindrical member 42 having a hollow portion 41 through which air can pass. A screw thread 43 may be formed on the outer circumferential surface of the connection portion 40 so as to be coupled or separated from the fan portion 10 and the moisture absorption portion 20 by rotation.

The fan unit 10 further includes a battery 12 for supplying power to the fan unit 11. The main unit 30 is connected to the battery and supplies power to the battery from the outside, A battery terminal 32 may be formed.

The fan unit 11 is powered by the battery. In addition, the battery may be connected to a battery terminal disposed on the outside of the main body 30. Therefore, when the dehumidifying module 50 is mounted on the dryer and regenerated, the battery terminal and the dryer may be connected to charge the battery. However, the battery terminal may be disposed outside the fan unit 10, unlike the one shown in the drawing.

Conventional disposable desiccants are dehumidified by a natural convection method, and therefore, they take a long time. The dehumidification module (50) of the present invention can provide a dehumidification effect faster than the conventional one by providing a small fan unit to form forced convection (air flow).

Fig. 4 is a perspective view showing a general garment storage space 60. Fig.

The dehumidification module can be manufactured to have a size enough to be easily inserted into a general garment storage space 60. Dehumidification module of this size can be manufactured to dehumidify about 50 ~ 60cc when dehumidification is used once. And, when it is regenerated by using a dryer, it can be used for dehumidification of a closet or the like at low cost.

[Formula 1]

The formula 1 is a calculation of the amount of moisture inside the garment storage 60 based on the average temperature and humidity of summer in a garment storage room 60 having a length of 10 characters (about 30 cm per person) generally used in the home. .

Table 1 above shows the calculation of the dehumidification amount per hour through the dehumidification module having the fan part and the battery forming the flow. Referring to this, the dehumidification module is capable of absorbing about 60 g of moisture per hour. As described above, since the humidity inside the garment storage 60 is about 23 g, the inside of the garment storage 60 can theoretically be dehumidified in 20 to 30 minutes.

FIG. 5 is a flowchart related to control for drying the dehumidifying module according to the present invention.

Referring to the drawings, the control for regenerating the dehumidification module of the dryer according to the present invention starts with a step (S10) of operating a heater for heating the air to regenerate the dehumidification module. At this time, the heated air can be blown. Regarding the moisture absorption amount of the regeneration module, the operation temperature and the heating capacity of the exhaust type dryer, regeneration of the dehumidification module can be performed in a short time. However, it may be necessary to operate for a certain period of time in consideration of the time during which the main body of the dryer is heated. The step of operating the heater that heats the air is a step considering the time that the dehumidifying module regeneration program is operated and the heater is operated so that the air can be sufficiently heated.

If the temperature of the heated air is equal to or higher than the preset regeneration temperature (a) (S20), the temperature of each air before and after passing through the dehumidification module can be measured. In addition, the temperature of the air before passing through the dehumidifying module (shear temperature, T _in ) may further include a step of comparing with a predetermined temperature (b) at which regeneration of the dehumidifying module can actively occur (S30).

Thereafter, the temperature difference between the air before and after passing through the measured dehumidification module may be compared with a predetermined end temperature difference value (S40). When the temperature of the air passing through the dehumidifying module (rear end temperature, T _out ) is larger than the value obtained by subtracting the end temperature difference value (c) from the front end temperature (T _in ), the regeneration of the dehumidification module is almost completed, And the heater can be stopped (S50). At this time, although the heater is stopped, only the blowing operation is performed to lower the temperature, and the residual heat remaining in the air can complete the regeneration of the dehumidification module.

On the other hand, after the step of measuring the temperature of each air before and after passing through the dehumidifying module, the temperature T _{out of the} air after passing through the measured dehumidifying module is compared with the predetermined no-load temperature d, And stopping the heater (S41). If the temperature of the air after passing through the dehumidification module (rear end temperature, T _out ) reaches a temperature close to the maximum temperature at which the dryer reaches the no-load condition, it is determined that the regeneration of the dehumidification module is completed and the heater is stopped .

The method may further include a step (S60) of stopping blowing by comparing the temperature of the air passing through the dehumidifying module with a predetermined end temperature after the heater is stopped.

The method may further include measuring a relative humidity of air passing through the dehumidifying module, and comparing the measured relative humidity with a predetermined finished relative humidity to stop the heater (not shown). Such a method of measuring and comparing the relative humidity causes air having a relatively high humidity to be discharged when the dehumidification module is regenerated and the relative humidity is rapidly lowered after the point of completion of regeneration. Can be effectively confirmed.

In general, the regeneration of the desiccant made of silica gel is carried out at a temperature of 110 to 120 degrees Celsius, and the operating temperature of the exhaust-type dryer is higher than that, so that it is possible to regenerate the desiccant (moisture absorber) in a relatively short time.

When the dehumidification module regeneration program is finished, the dryer may further include an alarm sounding step. This makes it easy for the user to know that the dehumidification module has finished its regeneration.

6A and 6B are detailed views illustrating an embodiment in which the mounting portion 160 is inserted into the lint filter inlet portion 170. FIG.

6A and 6B, an exhaust unit 150 is formed adjacent to the window 141 formed in the door, through which air is discharged from the drum to the lower side of the opening of the drum. A flow path plate 172 may be formed on the upper side of the exhaust part 150 along the outer periphery of the opening of the drum when a plurality of flow paths 173 for collecting air are formed when the air escapes from the drum.

The passage plate 172 is formed with a lint filter inlet 170 on which a lint filter (not shown) is mounted to filter foreign substances contained in the air discharged from the drum. The lint filter inlet 170 is formed so as to be able to manually clean the lint filter by inserting or separating the lint filter. At this time, the mounting portions 160 and 160 may be detachably attached to the lint filter inlet 170 from which the lint filter is removed.

Specifically, the mounting portion 160 may include a frame 161 and a detachable member 162.

The frame 161 forms an outer shape of the mounting portion 160 and is insertable into the lint filter inlet 170. Since the frame 161 must be insertable into the lint filter inlet 170, the frame 161 may be formed in a manner similar to that of the lint filter. A hook structure (not shown) may be provided on the outer surface of the frame 161 so as to be fixed to the lint filter inlet 170.

The detachable member 162 may be formed inside the frame 161, and the moisture absorbent portion may be detachable. As described above, the hygroscopic unit may have a rectangular shape, and the hygroscopic unit may be formed to be capable of being inserted and drawn out while being folded on the main body unit. In this case, the moisture absorption portion can be drawn out to the main body portion, attached to the detachable member 162, and the frame 161 can be inserted into the lint filter inlet portion 170 to execute the regeneration program of the moisture absorption portion.

At this time, the flow of the air flows in the horizontal direction (direction A) with reference to the drawing, it is bent in the downward direction (direction B), and then it can escape. The flow of this flow has an advantage that the dehumidifying module or the moisture absorber can be regenerated more efficiently.

7A and 7B are detailed views showing an embodiment in which the mounting portion is formed inside the drum on the flow path plate for collecting air, which is formed toward the exhaust portion.

7A and 7B, the mounting portion may include a locking portion 261 and a locking member 272. [

The latching part 261 may be formed on one side of the lint filter inlet formed adjacent to the exhaust part. The engaging portion 261 may be formed to cover a plurality of flow passages formed in the flow path plate 272 so that the flow escaping to the exhaust portion can be concentrated toward the dehumidifying module without being dispersed toward the lint filter inlet portion .

The fixing member 272 may extend from the engaging portion 261 toward the inside of the drum. In addition, the moisture absorbing portion 20 may be accommodated therein. However, unlike the one shown in the drawings, a dehumidifying module may be accommodated. In addition, a plurality of the fixing members 272 may be formed to accommodate both the moisture absorption unit and the dehumidification module.

8A and 8B are detailed views showing an embodiment in which the mounting portion is provided on the door side in the flow path plate.

8A and 8B, the mounting portion includes a cover member 361 formed to cover the exhaust portion, and a mounting member 362 formed to extend from the cover member 361. As shown in FIG.

The cover member 361 may be formed to cover the flow path plate so that the air inside the drum does not escape through the flow path plate 272 (see FIG. 7A). So that the exhaust portion can be covered while covering the flow path plate. And a through hole (not shown) through which the drum and the exhaust part are communicated so that air in the drum can escape to the exhaust part. The through-hole may be formed at a lower portion of a point where the lid member 361 and the mounting member 362 meet. This is to increase the efficiency by concentrating the flow of the flow when the moisture absorber or the dehumidification module is mounted on the mounting member 362.

The mounting member 362 may extend upward from the through hole so as to be observable in the door. Referring to FIG. 8B, a dehumidifying module is mounted. However, unlike the one shown in the drawing, a plurality of the mounting members 362 may be provided so that at least one of the moisture absorption unit and the dehumidification module is mountable.

In this case, the dehumidifying module includes a battery for supplying power to the fan unit, and the main body unit may include a battery terminal capable of supplying external power to the battery. The mounting unit may include a charging unit 363 configured to supply power to the battery terminal when the dehumidifying module is mounted.

9 is a partial detail view showing a state in which the mounting portion of the present invention is disposed in the inflow duct 430. FIG.

In this embodiment, the mounting portion is formed in the inlet duct 430 exposed on the rear surface of the dryer casing 110. At least one of the dehumidifying module 50 and the moisture absorber may be mounted on the mounting portion.

Referring to FIG. 9, at least a part of the inlet duct 430 may be exposed on the rear surface of the casing 110.

The mounting portion may be formed on one surface of the exposed surface of the inflow duct 430. It is noted that the mounting portion is formed on the upper surface 431 of the inlet duct 430 in the embodiment of the present invention. However, it may be formed on a different surface from that shown. However, the mounting portion is preferably installed later than the heater disposed in the inflow duct 430. That is, it is preferable that the dehumidifying module 50 or the hygroscopic module is dried after passing through the air flow heater in the inflow duct 430 and heated by the hot air. Meanwhile, a plurality of the mounting portions may be provided.

The mounting portion is formed to communicate with the inside of the inflow duct 430. Therefore, the mounting portion may be formed to push the dehumidifying module 50 or the moisture absorbing portion into the inlet duct 430.

9, a dehumidifying module 50 is inserted into the mounting portion. Referring to FIG. 3, the connecting portion 40 of the dehumidifying module 50 may protrude outwardly from the body portion and the fan portion. Accordingly, the connection portion 40 is hooked on the upper surface 431 of the inflow duct 430, so that the dehumidification module 50 can be prevented from being excessively introduced into the inflow duct 430.

When the dehumidifying module 50 is mounted on the mounting portion, a charging terminal (not shown) for charging the battery terminal 436 formed in the dehumidifying module 50 may be formed on the mounting portion.

Further, it is advantageous that the mounting portion is installed after the heater passes through the inlet duct 430, at the same time as the clothes drying function.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
