1 to 7, a direct-connection type humidifier 100 according to an embodiment of the present invention includes a casing 110, a water bottle 120, a humidification unit 130, and a cover 140.

The casing 110 forms the outer shape of the humidifier 100 and can be modified into various shapes. In addition, the casing 110 is partly embedded in the wall 1, such as a room, or is mounted on the wall 1. Of course, the casing 110 may be placed on the floor. Here, the wall 1 may be a panel of furniture or the like.

In particular, when the casing 110 is embedded in the wall 1, at least the front side is exposed. Therefore, the air is allowed to be discharged after entering the outside air.

When the casing 110 is mounted on the wall 1, the casing 110 is mounted by a separate bracket (not shown) or the like.

In addition, the casing 110 forms the atomizer 112 to discharge the evaporated moisture to the room and spray it. For the sake of convenience, the atomizer 112 is formed on the upper surface of the casing 110 exposed to the outside of the wall 1.

In addition, the casing 110 may have a hard cap 118 on the rear side. The cap 118 is embedded in the wall 1 to protect the casing 110 from the wall 1. At this time, since the cap 118 is embedded in the wall body 1 after being combined with the casing 110, the casing 110 can be firmly fixed. Of course, the cap 118 can be formed in various ways. The number and size of the fluid dispenser 112 are not limited.

Meanwhile, the water bottle 120 is accommodated in the casing 110 so as to be detachable from the casing 110. At this time, the water bottle 120 may be slidably inserted into the casing 110, or simply housed in the casing 110.

The water tank 120 serves to temporarily store the direct water supplied through the direct water pipe 10. Of course, the water bottle 120 may be integrally provided in the casing 110.

The direct water pipe (10) serves to supply water (direct water) from a faucet or water supply and drain to the water tank (120). Thus, the direct water pipe (10) feeds direct water into the water bottle (120) while being inserted into the casing (110).

At this time, the direct water pipe (10) is coupled to the casing (110) so as to be kept inserted into the casing (110) to prevent it from being separated from the casing (110) while being shaken by direct water pressure.

Of course, the water bottle 120 can be applied in various shapes and various materials. In addition, the water bottle 120 can be housed to be fixed inside the casing 110 by various methods.

The humidifying unit 130 serves to evaporate the direct water in the water bottle 120 in a natural manner or a heating method, and spray the water through the spray port 112 to the room.

In addition, the casing 110 is provided with a cover 140 so that the front side can be opened and closed so that the water bottle 120 can be drawn out and cleaned. At this time, the cover 140 can be deformed into various shapes, hinged to the casing 110, or completely detachable from the casing 110.

For example, the cover 140 is connected to the casing 110 in a top-opening manner by a shovel member 190. As a result, the sense of opening and closing operation of the cover 140 is significantly improved.

Particularly, after the cover 140 is opened, the user can insert or remove the water bottle 120.

The cover 140 may be provided with an operation unit 142 for operating the humidification unit 130 to adjust the humidification amount. The operation unit 142 can be applied in various ways, but it is applied as a rotary switch system for enhancing the interior feeling and for convenience of operation.

On the other hand, the direct water pipe (10) can interrupt supply of direct water by the supply interrupter (150).

Here, the supply interrupter 150 includes a water level sensor 152, an on-off valve 154, and a pressure-reducing valve 156.

The water level sensor 152 is fixed to the inner surface of the water bottle 120 so that the water level of the water bottle 120 can be detected in real time. The manner in which the water level sensor 152 is installed in the water tank 120 is assumed to be general.

At this time, since the water level sensor 152 is provided in the water bottle 120, the water bottle 120 can be restricted when the water bottle 120 is drawn out from the casing 110 for washing or the like. In order to prevent this, the water level sensor 152 may be connected to the power source by a connector (not shown).

The shutoff valve 154 is provided in the water line 10 to control the flow rate and the flow rate of the direct water flowing through the direct water pipe 10 by the set water level signal of the water level sensor 152. That is, the on-off valve 154 is closed when the water level sensor 152 detects the full water level, and is opened when the water level below the set level is sensed. The opening / closing valve 154 may be fixedly installed inside the casing 110.

Here, the on-off valve 154 can be applied as a solenoid valve.

In addition, a plurality of water level sensors 152 may be provided in the water tank 120 in the height direction. Therefore, when the water level sensor 152, which is located on the upper side gradually, senses the direct water in the water bottle 120, the on-off valve 154 is closed so that the flow amount of direct water is controlled to be reduced.

Also, the pressure reducing valve 156 is provided in the direct water pipe 10 for discharging the direct water flowing through the direct water.

In other words, the direct water can flow back to the outside of the casing 110 due to relatively high pressure to be discharged to the water bottle 120 and collide with the water bottle 120 at relatively high pressure, . In order to prevent this, the direct water pipe 10 is provided with a pressure reducing valve 156 to lower the direct water pressure.

Particularly, the opening / closing valve 154 is opened, and when the direct water is supplied to the water bottle 120, the user can open the cover 140.

In this case, in order to prevent the direct water from splashing out of the casing 110, the on-off valve 154 is turned off and the supply of the direct water can be stopped. To this end, the casing 110 may comprise a switch 180.

The switch 180 recognizes the closed state of the cover 140 so that the opening and closing valve 154 is operated by an external operation or by an external signal Thereby opening and closing operation.

When the cover 140 opens the front side of the casing 110, the switch 180 recognizes the open state of the cover 140, so that the open / close valve 154 can be opened or closed by an external operation for opening or an external signal It is switched to the closed state or maintained in the closed state.

In addition, when the opening / closing valve 154 malfunctions or malfunctions, direct water may flow out of the casing 110 while overflowing from the water bottle 120.

In order to prevent this, the supply interrupter 150 may further include a sub-valve unit 170.

That is, the sub valve unit 170 serves to additionally shut off the supply of the direct water when the set water level is supplied to the inside of the casing 110.

Here, the sub valve unit 170 includes a body 172, a link member 174, a buoyancy member 176, and an opening and closing operation member 178.

The body 172 is fixed to the inside of the casing 110 and particularly to the inside of the water bottle 120 and passes through the guide hole 173 in order to supply water to the inside of the water bottle 120 toward the humidifying unit 130 . Of course, the body 172 can be deformed into various shapes.

The link member 174 is hingedly connected to the edge of the guide hole 173 or the body 172. At this time, the link member 174 can be deformed into various shapes and hinged to the edge of the guide hole 173 or the body 172 in various ways.

In addition, the buoyancy member 176 is connected to the link member 174 and has buoyancy. Thus, the buoyancy member 176 ascends and descends in accordance with the amount of direct water stored on the side of the humidifying unit 130, in particular, the water bottle 120. Of course, the buoyancy member 176 may be hingedly connected to the edge of the guide hole 173, or to the body 172.

The opening and closing operation member 178 extends from the link member 174 or the buoyancy member 176 and functions to open and close the guide hole 173 according to the position of the buoyancy member 176. [ Of course, the opening and closing operation member 178 can be deformed into various shapes.

Accordingly, the sub valve unit 170 functions to intermittently supply the direct flow (supply) in response to the operation of the on-off valve 154 by the signal of the water level sensor 152, To control the supply of direct water.

When the opening and closing operation member 178 closes the guide hole 173, a support protrusion 179 may be formed on the inner side surface of the guide hole 173 to support the edge of the opening and closing operation member 178 .

On the other hand, the humidification unit 130 includes a shaft 131 and a disk 132.

The shaft 131 is mounted on the upper side of the water bottle 120 and rotated. At this time, the shaft 131 is rotated in one direction by the driving source 137.

A plurality of discs 132 are arranged on the shaft 131 along the axial direction, and are rotated together with the shaft 131. In addition, each of the disks 132 is partially submerged in the running water of the bucket 120. Thus, the disk 132 with the direct water is rotated to induce the direct water to evaporate.

The humidification unit 130 includes a suction unit 133, a duct 134, a blowing fan 135, and a heater 136. [

The suction part 133 is formed at one side of the casing 110 or the cover 140 to allow the inflow of outside air. For convenience, the suction portion 133 is provided on the cover 140. Needless to say, the size, number, and position of the suction portion 133 are not limited.

The duct 134 is provided inside the casing 110 to permit the flow of outside air in the direction of the spray nozzle 112 from the suction unit 133 and to discharge the evaporated water evaporated from the water bottle 120 to the outside And is flow-guided in the direction of the atomizer 112. That is, the direct water to be evaporated and the outside air to be introduced are mixed and then discharged to the room through the discharge grill portion 115 of the spray nozzle 112.

The air blowing fan 135 is provided in the duct 134 to forcibly generate the flow of the outside air. This improves the evaporation efficiency of the dripping water adhering to the disc 132, thereby increasing the humidifying force.

Particularly, the blowing fan 135 is provided in the casing 110 corresponding to the discharge side of the air including moisture. Thus, the air blowing fan 135 is operated to draw out moisture and air adhering to the surface of the disk 132. Therefore, wind noise is reduced compared with the case where the air blowing fan 135 is provided inside the casing 110 corresponding to the air suction side.

The heater 136 is provided in the duct 134 to heat the outside air flowing into the casing 110 to further increase the evaporation amount of the direct water stored in the water bottle 120.

That is, the outside air flowing through the suction unit 133 is passed through the heater 136 or heated by the heater 136, and then comes into contact with the running water adhering to the disk 132. Then, the direct water adhering to the surface of the disk 132 increases in temperature as evaporation power is increased. As a result, the humidifying power of the room is further increased.

Particularly, the dispenser 112 can form the dispensing grill part 115 to prevent the inflow of external foreign matter.

In addition, the duct 134 may include a sterilizing member 160 on the inner side to sterilize the outside air and the direct water.

In addition, the outside air flowing into the casing 110 is purified and then blown toward the water bottle 120. Thus, a filter member 138 is provided inside the casing 110. [

In addition, as the air blowing fan 135 sucks and discharges moisture and air adhering to the surface of the disk 132, the amount of outside air introduced into the casing 110 should be sufficient.

Thus, the cover 140 forms the auxiliary suction port 144 on one side. Accordingly, the outside air sufficiently flows through the suction portion 133 and the auxiliary suction port 144. [

In particular, the auxiliary suction port 144 is provided below the cover 140 to prevent foreign substances from entering.

On the other hand, the duct 134 can be assembled to be firmly fixed to the casing 110. By way of example, the duct 134 has a latching hook 172, and the casing 110 defines a latching groove 174 on the inside. Thus, when the duct 134 is inserted into the casing 110, the locking hook 172 is engaged with the locking groove 174, so that the duct 134 is assembled to the casing 110.

The casing 110 forms an outer shape of the humidifier 100, and can be partly embedded in a wall of a room or the like, or can be mounted on a wall. In addition, the casing 110 may be placed on the floor.

In addition, the casing 110 forms the atomizer 112 to discharge the evaporated moisture to the room and spray it. For the sake of convenience, the atomizer 112 is formed on the upper surface of the casing 110.

The casing 110 receives the direct water from the outside through the direct water pipe 10. For convenience, the direct water pipe (10) is provided below the casing (110).

Meanwhile, the water bottle 120 can be slidably housed in the casing 110. For convenience, the water bottle 120 is slidably received in the front side of the casing 110. In addition, the water bottle 120 may be completely housed in the casing 110 and then bound.

In particular, the water tank 120 serves to temporarily store the water supplied through the water pipe 10.

Of course, the water bottle 120 can be applied in various shapes and various materials.

The humidifying unit 130 serves to evaporate the direct water in the water bottle 120 in a natural manner or a heating method and spray the water through the spray port 112 to the room.

Particularly, the humidification unit 130 can be supported by the water bottle 120.

Here, the humidification unit 130 includes a shaft 131, a disk 132, a suction portion 133, a duct 134, a blowing fan 135, and a filter member 138.

A plurality of discs 132 are arranged on the shaft 131 along the axial direction, and are rotated together with the shaft 131. Thus, the disk 132 with the direct water is rotated to induce the direct water to evaporate.

The suction portion 133 is formed on both sides or one side of the casing 110 to allow the inflow of outside air. Needless to say, the size, number, and position of the suction portion 133 are not limited.

The duct 134 is provided inside the casing 110 to permit the flow of outside air in the direction of the spray nozzle 112 from the suction unit 133 and to discharge the evaporated water evaporated from the water bottle 120 to the outside And is flow-guided in the direction of the atomizer 112. That is, the direct water to be evaporated and the outside air to be introduced are mixed and then discharged to the room through the spray nozzle 112.

The air blowing fan 135 is provided to be supported on the upper side of the duct 134 or the water box 130 to forcibly generate the flow of the outside air. This serves to increase the humidifying power by improving the evaporation efficiency of the direct water on the disk 132.

The shutoff valve 154 is provided in the water line 10 to control the flow rate and flow rate of the direct water flowing through the direct water pipe 10 by the set water level signal of the water level sensor 152. That is, the on-off valve 154 is closed when the water level sensor 152 detects the full water level, and is opened when the water level below the set level is sensed.

Here, the on-off valve 154 can be applied as an electronic valve.

In addition, a plurality of water level sensors 152 are provided in the water tank 120 in the height direction. Therefore, when the water level sensor 152, which is located on the upper side gradually, senses the direct water in the water bottle 120, the on-off valve 154 is closed so that the flow amount of direct water is controlled to be reduced.

In other words, the direct water can flow to the outside of the casing 110 due to relatively high pressure to be discharged to the water bottle 120, and the water bottle 120 is damaged or impact sound as the water hits the water bottle 120 at relatively high pressure. In order to prevent this, the direct water pipe 10 is provided with a pressure reducing valve 156 to lower the direct water pressure.

On the other hand, the detecting member 122 is provided inside the casing 110 to detect a state in which the water container 120 is housed.

Particularly, the open / close valve 154 is opened and the user can draw out the water bottle 120 when the direct water is supplied to the water bottle 120.

In this case, in order to prevent the direct water from overflowing to the outside of the casing 110, the open / close valve 154 is turned off and the supply of the direct water can be stopped. To this end, the casing 110 is provided with a detection member 122.
