The present invention, as well as separated from the humidifier body, can be freely filled with water through the water inlet in the upper portion of the water tank as it is combined, and the water supply for the water supply and the heater / vibrator are separately provided and atomized (霧) It relates to an upper water supply humidifier using ultrasonic waves to automatically control the supply of water for heating and the operation of a heater and a vibrator for heating the water to an appropriate temperature, respectively according to the level of the atomization tank.

Humidifiers, especially in winter, are appliances for humidifying high temperature and dry indoor air to maintain a comfortable indoor environment. Depending on the method of humidification, the humidifier is heated, ultrasonic, fan-style and their respective advantages. Compounds etc. which combine these are known.

A heated humidifier generates steam by heating water with a heater or electrode, and an ultrasonic humidifier vibrates an oscillator located in the water by an electric signal of a specific frequency generated through an electric circuit to atomize the water. The fan humidifier is configured to supply water to the air in a specific manner, such as by granulating water by wind generated by rotating a fan installed on the surface at high speed.

Among the various humidifiers that humidify the air in various ways as described above, the ultrasonic humidifiers that are most widely used in each home are as follows.

Ultrasonic humidifiers, as shown in Figure 1, the main body 11 is a spray device (not shown) is built; A bucket 12 seated on one side of the upper surface of the main body 11; An injection pipe 13 through which atomized water is injected; It consists of a cover and the like covering the entire upper surface of the main body 11 in the state in which the bucket 12 and the injection pipe 13 are seated.

In this case, the injection pipe 13 may be formed integrally with the bucket 12, and may serve as a cover while the outer peripheral surface of the bucket 12 is exposed as it is without a cover.

In addition, the bucket 12 is provided with an inlet I for filling water on the bottom thereof, and the inlet I is detachably coupled to the lid C, and a central portion of the lid C is provided with a spring. The needle valve (V) is operated by the structure, the water supply and atomization process is as follows.

When the bucket 12 is placed in the bucket seating groove G on one side of the upper surface of the main body 11, the protrusion E of the center of the seating groove G is provided with a needle valve provided at the center of the lid C of the bucket 12. By pushing V into the bucket 12, the needle valve V is opened, and the water in the bucket 12 flows into the seating groove G, and this water flows into the flow path F of the upper surface of the main body 11. ) Flows into the atomization tank G 'provided with the vibrator 11A from the seating groove G, and is atomized by the vibrator 11A, and the atomized water passes through the injection pipe 13 to form the air outside the humidifier. Dispersed in the middle.

The symbol 'S', which is not described, is a water level sensor, which detects when there is no water in the atomizer G and cuts off the power input to the vibrator 11A.

The conventional ultrasonic humidifier as described above is a bottom water supply type, in which the inlet I is provided on the bottom surface of the bucket 12, and when the water falls into the bucket 12, the bucket 12 is necessarily seated in the groove G. After separating from the water bottle (12) upside down in the state to open the inlet (I) is inconvenient to fill the water in the water bottle (12).

That is, when lifting the water tank 12, the needle valve (V) is closed by a spring, in the state in which the needle valve (V) closed to turn the water tank 12 to remove the lid (C) to the inlet (I) Bar can be filled with water, there is a disadvantage that can not replenish the water in a state in which the bucket 12 is seated on the main body (11).

In order to solve the inconvenience of water injection, a humidifier bucket with a new structure has been developed, and the Korean Utility Model Nos. 359947 and 359948 describe the 'water refill system of the humidifier bucket' and the 'humidifier bucket'. 'Water replenishment structures' are posted respectively.

The two utility models, the upper water supply-type humidifier is provided on the upper surface of the water inlet, there is an advantage that the water can be injected into the bucket while the bucket is placed on the humidifier body.

However, the registered utility model No. 359947, the ground sensor and the microcomputer, which are important components for detecting the opening and closing of the lid provided at the inlet of the water bottle, are not shown in the cross-sectional view, and thus the coupling position and the correct working effect are not known. The bucket is generally detachable from the humidifier body for cleaning. Since the connection between the ground sensor and the microcomputer built in the body can only be made in contact, malfunctions may occur due to poor contact due to repeated use for a long time. Can be.

That is, the Utility Model No. 359947 has a grounding sensor in the water tank, which complicates the structure of the water tank, which is simply filled with water, and at the same time, it requires a great deal of care to prevent damage to the grounding sensor during cleaning. In addition, there is a disadvantage that the management of the contact portion is required to maintain the contact connection of the ground sensor and the microcomputer.

And, the sensor is provided in the inlet of the water tank, the water filling the water tank to close the lid only the sensor opens the electronic opening and closing valve while the sensor operates, only in this state the water in the water tank through the electronic opening and closing valve ( Or atomizer), there is an inconvenience that the humidifier does not work unless the lid is closed after filling the water tank. That is, after filling the water tank, the lid must be closed.

The registered utility model No. 359948 has a structure in which the inner space of the water tank is separated into upper and lower rooms by a separator, and the upper and lower rooms are connected by a vertical pipe combined with a water control flow member. The water is supplied to the humidifier main body by manually rotating the member so that the water in the upper room flows into the lower room. Whenever water supply is required, a person must rotate the water control flow member one by one. There is this.

The present invention was devised to solve all the problems of the conventional lower water supply or upper water supply ultrasonic humidifier, and the water injecting water into the water tank is simple while the water tank structure is not separated from the water humidifier body. Not only is it possible, it is possible to make normal atomization even without the lid of the water tank, and it is possible to heat the water to the appropriate temperature in the water level, but it provides an upper water supply humidifier that can control the operation of the heater with the water level sensor. There is a purpose of the present invention.

The object of the present invention is achieved by a pair of water level sensors for sensing the water level step by step, and the sealing structure of the bottom water supply port of the water tank.

The upper water supply humidifier of the present invention is an ultrasonic humidifier, and the normal operation of the humidifier is possible even without closing the lid of the bucket after injecting water, as well as injecting water into the bucket while the bucket is coupled to the humidifier body. In addition to the water supply from the water tank according to the level of the atomization tank where the water is atomized by the vibrator, the water level sensor automatically controls the operation of the heater to warm the water to the proper temperature and the operation of the vibrator to atomize the water. have.

The upper water supply humidifier of the present invention as described above, compared with the conventional upper water supply humidifier, a pair of water level sensor provided in the atomization tank; Structural features of the bottom water inlet sealing structure of the water tank, looking at each as follows.

The pair of water level sensors may include: a water supply sensor for controlling an electronic open / close valve for allowing water to flow into or out of the tank; It consists of a heater for heating the water flowing into the atomization tank below 100 ° C. and a sensor for heater / vibrator operation for controlling the operation of the vibrator for atomizing the water together.

At this time, each of the water level sensor, upright on the bottom of the atomization tank and the rod-shaped posts therein; The center is penetrated by the post, and the outer circumferential surface of the post is reciprocated in the up and down direction according to the water level, and is composed of a float with a magnet embedded therein. When the float is close, the switch inside the post is turned on. It is a structure that turns on / off

Of the above two sensors, the water supply sensor serves to control the opening and closing of the electromagnetic opening and closing valve coupled to the flow passage connected to the atomization tank in accordance with the water level, and the heater / vibrator operation sensor is water flowing into the atomization tank. Heater and vibrator to heat the role of on / off depending on the water level.

As described above, the two sensors that control the operation of the solenoid valve and the heater / vibrator according to the water level are different from each other at the highest and lowest positions of the float trajectory. The water level detection height increases in the order of the float low point of the sensor → the float high point of the heater / vibrator operation sensor → the float high point of the sensor for solenoid valve operation. The operation behavior of the two sensors is as follows.

If the float of both sensors is at the lowest point because there is no water in the atomization tank, the heater and the vibrator are stopped, but the solenoid valve of the flow path from the bucket to the atomizer is open. The water in the water tank flows into the atomization tank through the open and closed solenoid valve, and as the water flows in, the float of the two sensors rises together with the solenoid valve continuously open. The vibrator and heater are activated as they rise above their lowest point.

In addition, the float of the heater / vibrator operation sensor reaches the highest point among the two floats that continuously rise together, but the float of the sensor for the solenoid valve operation does not reach the highest point. It continues to be supplied to the atomization tank through.

As water is continuously supplied to the atomization tank, the float of the solenoid valve operation sensor reaches its maximum while the float of the heater / vibrator actuating sensor maintains the highest point. As soon as the peak is reached, the electronic switch valve closes after a certain period of time after signaling the microcomputer to stop supplying water.

That is, during normal operation of the humidifier, the float of the heater / vibrator operation sensor maintains its highest point, and as the water is atomized and sprayed out of the humidifier, the float of the solenoid valve operating sensor floats between the highest point and the lower part close to the highest point. While moving, the solenoid valve is repeatedly opened and closed.

In addition, when the water supply to the atomization tank is stopped even though the solenoid valve is open because there is no water in the water tank, as the water is injected, the float of the sensor for operating the solenoid valve is lowered initially and then the solenoid valve The float of the actuation sensor and the float of the heater / vibrator actuation are lowered together, and the heater / vibrator is stopped when the float of the solenoid valve actuation sensor reaches the lowest point.

When the operation of the heater / vibrator is stopped as described above, the heating and atomization of the water also stops, and the water of the atomization tank no longer decreases, and thus, the sensor for operating the solenoid valve is no longer lowered. .

That is, the heater / vibrator is also stopped when water remains in the atomization tank. At this time, of course, the solenoid valve is open.

Humidifier of the present invention that operates as described above, the water tank can be opened without opening the lid of the upper portion of the water in the combined state without separating the bucket from the humidifier body, the water tank can be removed without closing the lid of the bucket The water does not overflow through the seating groove or the atomization tank of the humidifier body coupled to the bar, which is achieved by the sealing structure between the electronic opening and closing valve and the water tank and the humidifier body.

That is, the bottom surface of the bucket constituting the humidifier of the present invention is provided with a water inlet having a needle valve, the water inlet is detachably inserted into the seating groove of the humidifier main body, the outer circumferential surface of the water supply port or the inner peripheral surface of the seating groove The sealing member made of a flexible elastic material such as silicone, rubber, etc. is coupled to at least one side, thereby preventing the outflow of water through the water supply port outer circumferential surface and the seating groove inner circumferential surface.

For example, when the water inlet is inserted into the seating groove while the inner circumferential surface of the pipe type sealing member is tightly coupled to the outer circumferential surface of the water inlet, the outer circumferential surface of the sealing member is in close contact with the inner circumferential surface of the seating groove, and the sealing member is separated from the water inlet. It should be possible to easily insert and remove the water supply port into the seating groove without it. It is desirable to protrude a plurality of flexible ring-type sealing protrusions having elastic force along the outer circumferential arc at regular intervals in the axial direction on the outer circumferential surface of the sealing member. Do.

That is, when the water inlet is inserted, the sealing protrusion of the sealing member is elastically deformed along the up and down direction, so as to be in close contact with the inner circumferential surface of the seating groove, so that a gap in which water can flow between the inner circumferential surface of the seating groove and the outer circumferential surface of the water inlet is provided. Therefore, the water supply and the operation of the humidifier are possible even in the state in which the water container is coupled to the humidifier body without opening the lid to the inlet of the upper part of the water bottle without opening the lid.

In addition, the heater is for heating the water supplied to the atomization tank to humidify as warm water when the weather is cold, and is operated by the heater / vibrator operation sensor. It is desirable to have a separate heater main switch to prevent it from continuing to operate, so that the heater can be operated by the heater / vibrator actuation sensor only when the main switch is on.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

As shown in the upper water supply humidifier of the present invention,

Upper and lower injection parts on which the upper lid C and the lower lid C 'each having a water inlet D having a spring s operated needle valve V mounted on the center and a spring s operated needle valve V are detachably coupled to each other. A bucket 21 having a sphere I) I ';

An upward open atomization tank G 'having a pair of water level sensors S1 and S2 and a vibrator 11A on the bottom surface is formed on one side of the upper surface, and the water supply port D of the water tank 21 is repeated. Is inserted into and detachably coupled to the atomization tank (G ') by the flow path pipe (F') coupled to the electromagnetic opening and closing valve (V '), and provided with a protrusion (E) for opening the needle valve (V). A humidifier body 22 having an upwardly open seating groove G formed on the other side of the upper surface thereof;

The inner circumferential surface is elastically tightly coupled to the outer circumferential surface of the water supply port (D) of the water tank 21, and protrudes along the arc direction of the outer circumferential surface at regular intervals in the axial direction so that the ring-shaped seal is elastically in close contact with the inner circumferential surface of the seating groove (G). It consists of the tubular sealing member 23 etc. in which many protrusions E 'protruded.

Reference numeral 24 denotes a "heater" for heating the water flowing into the atomization tank G ', and "25" is a "blower" for injecting atomized water out of the humidifier.

The pair of water level sensors S1 and S2 reciprocate each float F1 and F2 along the outer circumferential surface of each post P1 and P2 in an up and down direction by a change in the water level. One sensor (S1) of the two sensors (S1) (S2) is a sensor for heater / vibrator operation, the other (S2) is a sensor for solenoid valve operation, from the bottom two sensors (S1) (S2) The height of the lowest point and the highest point at which the float F1 (F2) reaches) is the lowest point of the float F2 of the sensor S2 for solenoid valve operation → the lowest point of the float F1 of the sensor S1 for heater / vibrator operation → Highest point of float (F1) of heater / vibrator operating sensor (S1) → Highest point of float (F2) of solenoid valve operating sensor (S2).

At this time, the solenoid valve operation sensor S2 opens the solenoid valve V 'from the lowest point of the float F2 to just before the highest point, and closes at the highest point, and the sensor S1 for heater / vibrator operation is The heater / vibrator is stopped at the lowest point of the float F1, and the heater / vibrator is operated immediately after deviating from the lowest point to the highest point.

The sealing member 23 coupled to the water inlet D and the outer circumferential surface of the water supply port D is normally operated without closing the lid C of the water tank 21 seated in the seating groove G of the humidifier main body 22. It should be able to be operated so that there is no gap between water supply port (D) outer circumference and seating groove (G) inner circumference.

Therefore, the shape of closely coupling the sealing member 23 to the inner circumferential surface of the mounting groove (G) is also irrelevant, in order to facilitate the cleaning, etc., as shown in Figure 5, the upper and lower end diameters of the water supply port (D) The upper and lower ends, i.e., larger than the central diameter, and insert the outer peripheral surface of the small diameter portion into the inner diameter of the elastic sealing member 23 to insert the inner peripheral portion of the water supply port I in the center portion and the sealing member 23. When the inner peripheral surface is in close contact, it is more preferable that the sealing member 23 can be more stably maintained by the upper and lower stepped portions J.

In addition, the cross-sectional shape of the ring-shaped sealing protrusion (E ') protruding in multiple stages in the up and down direction on the outer circumferential surface of the sealing member 23 is preferably a wedge-shaped or triangular shape that becomes narrower toward the outside. D) The maximum outer diameter of the sealing protrusion E 'of the sealing member 23 in the state coupled to the outer peripheral surface is larger than the inner diameter of the seating groove (G).

That is, when the water inlet D coupled with the sealing member 23 is inserted into the seating groove G, the widthwise outer end of the sealing protrusion E 'is elastically upwardly deformed, thereby upwardly deforming. Since the sealing protrusion E 'is in close contact with the inner circumferential surface of the mounting groove G by the elastic force, a gap is not formed between the inner circumferential surface of the mounting groove G and the outer circumferential surface of the water inlet D.

In addition, the lower lid (C ') coupled to the lower inlet (I') of the bucket 21 can be integrated with the bucket (21), so configured separately, the smaller the size of the upper lid (C) This is to form a lower diameter injection hole I 'with a large diameter in order to facilitate the cleaning of the inside of the water tank 21 while improving the appearance.

However, while integrating the lower lid (C ') with the bucket 21, the upper inlet (I) and the lower lid (C) may be expanded to facilitate the internal cleaning of the bucket (21).

As described above, the upper water supply humidifier of the present invention has improved operation accuracy because the operation and water supply of the heater and the vibrator are automatically performed by a pair of water level sensors, and the coupling structure of the water supply port and the sealing member Thereby, even when the lid is opened, the humidifier can be operated normally without overflow of water, and at the same time, water can be injected into the bucket.
