1, a suction hole 11 for sucking the outside air into the dryer and an exhaust hole 12 for discharging the air inside the dryer to the outside are formed in the lower portion of the cabinet 10, It is advantageous that the suction holes 11 and the exhaust holes 12 are located at positions that are both up, down, front, rear, and side positions of the cabinet 10, but are symmetrical with respect to each other.

The control panel 20 may include a display 21 for displaying an operation state of the dryer and at least one operation button 22 for receiving a command from the user. It is advantageous.

The drawer 30 may include a handle 31 for allowing the user to easily draw the drawer from the dryer and a rack 32 for receiving and holding the drying object inside the rack 32, It is in the form of a mesh with many holes to allow air to flow well into the other drawer, that is, to allow air flow.

The dryer 1 according to the present invention may further include a high-temperature air supply unit 40 for supplying the drying object accommodated in the drawer 30 with the high-temperature dry air to perform a drying function, The air supply 4 is advantageously arranged underneath the dryer so that the hot air can be easily exchanged with the drying object supported in the rack of the upper drawer as it travels upward.

The high temperature air supply unit 40 includes a motor 41 for generating a rotating force, a fan 42 for generating a flow of air while rotating in accordance with the rotational force of the motor 41, A fan cover 43 for protecting the fan 42 by preventing other objects from being placed in the turning radius of the fan 42, a heater 44 for applying heat to the air moved by the fan 42, And a filter 45 for filtering the impurities mixed in the air entering from the outside via the filter 45. The filter 45 may be mounted on the suction hole 11. [

The rotation of the motor 41 and the heat generated by the heater 44 can be controlled by a control unit included in the control panel 20. In addition, it is advantageous that the heater 44 can regulate the amount of heat so as to change the temperature of the air to be heated, and it is necessary to adjust the temperature of the air differently depending on the object to be dried .

The control unit of the control panel 20 provides various operating conditions according to the type of the object to be dried so that the user can select the object. The control panel 20 allows the user to designate the drying time and the drying temperature in various stages as drying conditions, , One or more of the amounts of the object to be dried may be designated as drying conditions.

For example, a short drying time and a high drying temperature may be set as a drying condition for drying a small amount of clothes of a cotton material, and a long drying time and a low drying temperature may be set as a drying condition for a shoe. That is, the air can be forcedly supplied to the space in which the object to be dried is accommodated according to the operation condition designated by the user, and the temperature or air supply time of the air can be controlled differently.

The dryer 1 of the present invention includes an open sensing device (not shown) to prevent malfunction of the dryer or to reduce unnecessary power consumption. The controller 1 senses the open state of each drawer 30, The drying operation can be stopped when at least one drawer 30 is open.

FIG. 2 illustrates a folded and unfolded state of a rack in a drawer of a dryer according to an embodiment of the present invention.

1, a plurality of drawers of two or more are arranged side by side in the up-down direction in a state where the width in the up-down direction is smaller than the width in the left-right direction or the back-and-forth direction. And thus the height of the drying object that each drawer can accommodate may be limited. To solve this problem, a rack 32 in the form of a mesh for receiving and supporting the object to be dried in the drawer 30 of the dryer according to the present invention can be folded and removed from the drawer 30.

The drawer 30 has a drawer 31 formed on the front wall 33 of the drawer and supports the rack 32 so as to prevent the rack 32 from descending downward on the inner side surface of both side walls 34, A guide rail 35 may be formed to serve as a guide when the guide member 32 is folded. The present invention is not limited to this, and the guide rail 35 may be attached to the front wall 33 rather than both the side walls 34, And an inner surface of the rear wall, so that the rack 32 may be opened or folded sideways.

The racks 32 are folded into a so-called bellows shape, that is, the racks 32 are folded and folded at a plurality of equally spaced joints. Each of the racks 32 is folded in the drawer with a neighboring joint And the spacing between the joints may be less than the height of the drawer to which the rack belongs.

Figure 3 illustrates the use of two neighboring drawers as a drying space by folding the rack of the upper drawer in accordance with an embodiment of the present invention and in order to dry a drying object higher than the drawer, By folding the rack of one drawer, two neighboring drawers can be used as one drying space.

When the pressure of the fan 42 is lowered by the rotation of the motor 41, the external air entering the inside of the dryer through the suction hole 11 and the filter 45 due to the pressure difference, The air is heated by the heater 44 to rise to the upper side and take moisture from the object to be dried and is discharged to the outside of the dryer through the exhaust hole 12. [ Since the rack 32 of the drawer 30 is in the form of a mesh, the hot air blown by the fan 42 can be transmitted to the upper side without being disturbed.

Next, the method of treating the dry air of the dryer will be briefly described.

FIG. 5 illustrates an embodiment in which the drying method of the exhaust system of the present invention is applied to the dryer of the present invention, and FIG. 6 illustrates an embodiment in which the drying method of the condensing system is applied to the dryer of the present invention.

5, external air In drawn through the suction hole 11 is heated to a high temperature by the heater 44, and air flows in the dryer by the fan 42 to be contained in the drying object (Out) while being absorbed moisture and discharged through the exhaust hole 12 to the outside. In the embodiment of FIG. 6, the air discharged through the exhaust hole 12 while absorbing moisture is condensed through the heat exchanging part 50 cooled by the cooling fan without being discharged to the outside, And is sucked into the dryer again by the fan 42 and recirculated. The moisture removed from the heat exchanging part 50 is contained in the storage container 15.

The motor 41 and the fan 42 are arranged near the inlet of the flow passage, that is, the suction hole 11, and the air flowing in from the outside of the motor 41 The heat is firstly preheated by the heat to improve the heat efficiency. In this case, the effect that the motor 41 is cooled by the outside air can also be obtained.

FIG. 7 shows an embodiment in which the drying method of the exhaust system capable of heat recovery is applied to the dryer of the present invention.

In the embodiment of FIG. 7, the air (Out) that has passed through the exhaust hole (12) is discharged to the outside, but the outside air (In) sucked through the suction hole (11) And the moisture is removed. 7, one side of the heat exchanger is provided with two side ducts 13 through which air passes through the dryer, and air (Out) discharged through the exhaust hole 12 and air The external air (In) sucked through the suction hole (11) passes through the respective adjacent flow passages so that heat exchange occurs at the interface between the two adjacent flow passages, thereby improving the heat efficiency.

8 shows a side duct 13 that allows heat exchange for transferring the heat of the exhaust air to the sucked air. As shown in the left side, a partition wall is provided in the middle of the side duct 13 as one flow channel, The heat exchange is performed in the partition wall by allowing the exhaust air (Out) and the intake air (In) to pass through the partition wall, or the flow pipe through which the intake air (In) So that heat exchange can be performed on all the surfaces of the flow pipe through which the intake air In passes.

FIG. 9 illustrates a state in which a drawer with a folded rack is connected to a neighboring drawer to move to a single drawer according to an embodiment of the present invention.

It is advantageous for the user's convenience to allow the rack 32 to move together with the folded drawer 30 and other neighboring drawers 30 that share a drying space, e.g., a drawer beneath the drawer with the folded rack. To this end, a latching device (or a locking device) 36 may be provided on the side of the front wall 33 of the drawer 30 so as to be connected to the lower drawer when the rack 32 is folded.

For example, as shown in Fig. 9, a pliable latching device 36 is formed below the side of the front wall 33 of the drawer 30 and can move up and down, In the unfolded state, the protruded one is hooked on the rack 32 so that the other protruding upper side does not interfere with the lower drawer 30 and the two racks move separately. However, when the rack 32 is folded, One of the devices 36 is not lowered by the thickness of the rack 32 because it does not hang over the rack 32 and the other side of the latching device 36 interferes with the front wall 33 of the lower drawer 30 The lower drawer is bound and the two drawers are connected. Thus, when a user pulls one or more knobs 31 of two drawers 30, the two drawers move together.

10 shows another embodiment of a latching device for connecting to a neighboring drawer, wherein a latching device 36 'is provided on the side of the front wall 33 of the drawer 30 and is moved up and down, The user may manually manipulate the latching device 36 'or detect the folding of the rack 32 and thereby automatically control the height of the latching device 36'. Alternatively, an electromagnet 36 '' may be provided as one of the latching devices above and below the front wall 33 of the drawer 30, and two adjacent electromagnets 36 &Quot;, or no force is applied between them so that the user can draw both drawers simultaneously or draw them separately.

FIG. 11 illustrates an embodiment in which the flow of air through the detour duct is smooth.

However, when the object to be dried is placed on the rack 32, the flow of air (flow path) is blocked by the object to be dried and the flow path resistance is lowered There is a possibility that the object to be dried which is placed at a place where a large load is applied to the enlarged motor 41 and the flow path does not sufficiently dry.

In order to solve such a problem, the dryer according to the present invention can provide the bypass duct 14 so that the flow path can be efficiently distributed in the drying space. Dry air is advantageously delivered directly from the lower drawer to the upper drawer through the open hole in the rack 32, but not by the drying object, so that dry air is drawn into the upper space of the drawer 30 The user can move to the upper drawer by using the bypass duct 14 connecting the adjacent two drawers 30 in the downward direction.

11, the solid line indicates the flow of air when the flow path resistance is low and the normal flow path is formed, and the dotted line indicates the avoidance flow caused by the bypass duct in the state where the flow path resistance is large due to the object to be dried.

11, the bypass duct 14 is formed in the left and right inner walls of the cabinet 10 so that only two neighboring drawers are connected up and down so that the flow path can be formed in a zigzag shape, The position is formed such that one wall and the opposite wall are staggered from each other. 11, the first drawer is interconnected via the bypass duct 14 at the left inner wall and the layer with the hot air supply 40 below, and the first drawer and the second drawer are connected to the bypass duct 14 at the right inner wall And the second drawer and the third drawer are connected to each other through the bypass duct 14 at the left inner wall and the exhaust hole 12 can be formed at the upper right of the third drawer. That is, one of the drawers can communicate with the upper drawer via the bypass duct 14 and the other can communicate with the lower drawer via the bypass duct 14, based on one drawer. A duct connection hole 37 is provided on the side of the drawer 30 where the bypass duct 14 is provided, that is, on the left and right walls so that the drawer 30 and the bypass duct 14 can communicate with each other.

When the detour duct 14 is formed on the rear wall of the cabinet 10, the detour duct 14 and the duct connecting hole 37 must be provided on the front wall 33 of the drawer 30. [ Alternatively, the bypass duct 14 may be formed in the side wall 34 of the drawer 30, that is, between the inner wall and the outer wall of the side wall 34. In this case, 34 is provided with a duct connection hole 37. One side wall 34 is connected to the upper drawer while the upper side is connected to the upper drawer while the other side wall 34 is connected to the lower drawer through the lower side.

11, a thermistor 46 may be disposed at the outlet of the heater 44 of the hot air supply unit 40 to sense the temperature of the air. When the air measured by the thermistor 46 reaches a certain temperature, the heater 44 can be turned off and the heater 44 can be turned on when the temperature falls below a predetermined temperature. The control unit can determine the degree of flow resistance, that is, whether the flow path is blocked or not, based on the on / off pattern of the heater 44. Based on this, if the induction resistance is high, To indicate that it is necessary to relocate the drying object.

In the embodiment of FIG. 11, air spreading in a plane by the fan 42 is directed downward at the lower end of the dryer in which the hot air supply unit 40 is placed, that is, below the lowermost first drawer 30 An air guide 47 may be formed. 11, a plurality of air guides 47 are disposed so as to generate a rising airflow at a relatively close position, a middle position, and a far position in the hot air supply unit 40, respectively . That is, one or more air guides may be disposed in each of the air guides 47 at at least two positions based on the distance from the hot air supply unit 40. The vertical cross section of the air guide 47 may be a parabolic shape in which the height of the air guide 47 increases as the distance from the fan 42 increases.

12, when viewed from above the dryer, for example, an air guide 47 disposed at a position far from a near position is positioned in a radial direction Within the range of the above-mentioned range). Similarly, the cross section cut in the radial direction of the air guide 47 is parabolic, and the cross section of the air guide 47 cut in the circumferential direction at the same radius from the center of the fan 42 has the highest height at the center, The air guide 47 may be formed in an inverted parabolic shape so as to guide the air even in an area where the air guide 47 is not formed.
