The present invention, as well as separated from the humidifier body, as it is combined can fill the water freely through the water inlet in the upper portion of the bucket, means for blocking or allowing the flow of water injected into the atomization tank of the humidifier body from the bucket The present invention relates to an upper water supply humidifier with a floating valve actuated by buoyancy.

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 ultrasonically vibrates a vibrator located in the water by an electric signal of a specific frequency generated through an electric circuit to atomize the water. Each humidifier supplies 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.

An ultrasonic humidifier (hereinafter simply referred to as a "humidifier") includes a main body 11 having a spray device (not shown in the drawing) as shown in FIG. 1; 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. After flowing into the atomization tank (G ') having a vibrator (11A) from the seating groove (G) through the atomization is atomized by the vibrator (11A), the atomized water is outside the humidifier through the injection tube (13) Is dispersed in the air.

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 by contact, malfunctions may occur due to poor contact due to repeated use for a long time. have.

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.

In addition, the conventional upper water supply humidifier is coupled to a valve operated by an electrical signal, such as an electronically open and close valve, the life of the contact with the water may not be long due to the nature of contact always, and the operation of the humidifier in the event of failure. Of course, the repair cost is expensive disadvantages.

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 has been devised to solve all the problems of the conventional lower water supply or upper water supply humidifier, and it is possible to inject water into the water tank while the water tank is simple and the water tank is not separated from the humidifier body. In addition, normal atomization is possible even when the lid of the water tank is not closed, and it is possible to reduce the probability of valve failure and improve durability by not using an electronic valve operated automatically by an electric signal for water supply. In addition to being able to achieve the above, it is an object of the present invention to provide an upper feed water humidifier, which is relatively inexpensive to repair.

The above object of the present invention is achieved by a floating valve floating by the water filled in the atomization tank of the humidifier main body.

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. The technical feature of the present invention is that the water supply from the water tank is controlled by a mechanical valve, that is, a buoyant float valve using buoyancy, in accordance with the level of the atomization tank in which water is atomized by the vibrator.

Compared with the conventional upper water supply humidifier, the upper water supply humidifier of the present invention as described above, a floating valve that is connected to the passage pipe and the atomization tank, that is, the water inlet hole, which is a passage of water supplied from the bucket seat groove to the atomization tank There is a structural feature.

And, the end side of the atomization tank of the flow path pipe connecting the flow path pipe and the atomization tank is vertical, and one end of the flow path pipe meets perpendicularly to the bottom surface of the horizontal atomization tank, and the bottom surface is smaller than the hollow cross-sectional area of the flow path pipe. The through hole, that is, the water seating hole is formed through the bottom of the atomization tank through the bottom surface, the floating valve is located across the atomization tank and the water inlet hole and the flow path to open and close the water inlet hole, look at the floating valve as follows.

The floating valve includes a float member located in the atomization tank of the humidifier main body in which the vibrator is located and filled with water, and which floats according to the level of the atomization tank; A connection member extending downwardly into the flow path through a water inlet hole having a flat cross-sectional area smaller than that of the float member at the center of the bottom surface of the float member; It is coupled to the lower end of the connecting member, and consists of a valve member having a flat cross-sectional area larger than the water inlet hole.

The floating valve having the structure as described above opens and closes the water inlet hole between the atomization tank and the flow path according to the level of the atomization tank. When there is no water or insufficient water in the atomization tank, the float member does not float in the atomization tank. If the bar is not sufficiently injured, the bottom of the atomization tank in contact with the bottom of the water inlet hole and the upper surface of the valve member located inside the flow path tube are not in contact with each other.

That is, when the water inlet hole is open and there is water in the bucket, the water in the bucket flows into the atomization tank through the flow pipe and the water inlet hole from the mounting groove of the humidifier body.

As the water level of the atomization tank increases, the float member located in the atomization tank rises, and the upper surface of the valve member and the bottom surface of the atomization tank which are moved upward from the flow path inside the water inlet hole by buoyancy applied to the float member are close to each other. I start to touch them.

At this time, if there is a gap between the upper surface of the valve member and the bottom of the atomization tank, the buoyancy applied to the float member is increased as the water level of the atomization tank becomes higher, and the water inlet hole is brought into close contact with the upper surface of the valve member and the bottom of the atomization tank. By being completely closed, the inflow of water into the tank is blocked.

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.

FIG. 6 is a water supply port constituting an upper water supply humidifier with an embodiment. An exploded perspective view of the member and the mounting groove is shown.

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

The upper lid C1 is detachably coupled to the upper inlet I _U and the lower lid C2 is provided with a water inlet D equipped with a spring s operating needle valve V in the center thereof. Lower injection hole (I _L ) is coupled to each other, the water tank 21 formed on the upper and lower surfaces, respectively;

An upward opening atomization tank (G ') having a water level sensor (S) and a vibrator (22A) on the bottom surface is formed on one side of the upper surface, the needle valve in the inner diameter portion into which the water supply port (D) of the water tank 21 is inserted. (V) Cylindrical water inlet I _W having an opening projection E is projected to the center of the bottom _and at the same time the water inlet I _W is connected to the atomization tank G 'by the flow pipe F'. A humidifier body 22 having an upper open seating groove G having a lower opening C2 coupled to the bucket 21 to be detachably inserted and coupled to the bucket 21 at an upper surface thereof;

A flow path tube (23A) located in the atomization tank of the humidifier main body (22) and a water inlet hole (H) having a flat cross-sectional area smaller than the float member (23A) at the center of the bottom surface of the float member (23A). F ') floating valve 23, etc., which is composed of a connecting member 23B extending downwardly and a valve member 23C coupled to the lower end of the connecting member 23B and having a flat cross-sectional area larger than the water inlet hole H. It is made, including. Reference numeral "13" denotes "injection tube" into which atomized water is injected.

At this time, the inner diameter of the water inlet hole (H) is relatively larger than the diameter of the bar or rod-type valve member 23C bar, while the floating valve 23 is moved more than necessary in the horizontal direction when moving up and down the valve member (23C) And close contact with the bottom surface of the atomization tank in contact with the bottom of the water inlet hole (H), that is, the opening and closing state of the floating valve 23 may not be complete.

Therefore, the inner circumferential surface of the water inlet hole (H) may be formed to protrude the guide member (L) to guide the outer surface of the valve member (23C) to minimize the horizontal movement.

And, in the state in which the water tank 21 is coupled to the seating groove G of the humidifier main body 22, the needle valve V of the water tank 21 is always opened, and the outer circumferential surface of the water tank water supply port D is opened. In order to prevent the water of the water tank 21 from leaking through the inner circumferential surface of the water injection hole I _W and the seating groove, a sealing member may be interposed between the outer circumferential surface of the water supply port D and the inner circumferential surface of the water injection hole I _W.

That is, for example, a pipe-type sealing in which a plurality of ring-shaped sealing protrusions E 'protrude along the arc direction of the outer circumferential surface at regular intervals in the axial direction and elastically closely contact the inner circumferential surface of the water inlet I _W. It is also preferable to elastically couple the inner circumferential surface of the member 24 to the outer circumferential surface of the water supply port D of the bucket 21.

The upper and lower end diameters of the water supply port D are made larger between the upper and lower ends, that is, larger than the central diameter, and the inner peripheral surface of the sealing member 24 is elastically tightly coupled to the small central diameter outer peripheral surface to seal the sealing. It is also possible for the member 24 to be more stably held 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 24 is preferably a wedge-shaped or triangular shape that becomes narrower toward the outside. D) The maximum outer diameter of the sealing projection (E ') of the sealing member 24 in the state coupled to the outer peripheral surface should be larger than the inner diameter of the water injection port (I _W ).

That is, when the water inlet D coupled with the sealing member 24 is inserted into the water inlet I _W , the widthwise outer end of the sealing protrusion E ′ is elastically upwardly deformed, which is upwardly deformed. As the sealing protrusion E 'is in close contact with the inner circumferential surface of the seating groove G by the elastic force, a gap is not formed between the inner circumferential surface of the water injection hole I _W and the outer circumferential surface of the water supply port D.

In addition, the water level sensor (S), the rod-shaped post (P) upright on the bottom of the atomization tank and the built-in switch; In the state in which the center is penetrated by the post P, the float reciprocates along the outer circumferential surface of the post P in the up and down directions according to the water level, and is composed of a float F " The switch inside the post P is turned on / off when F "

In addition, the lower lid C2 coupled to the lower inlet I _L of the bucket 21 may be integrated with the bucket 21. The separate lid may be configured separately so that the size of the upper lid C1 may be small. In order to improve the quality, the lower inlet I _L having a large diameter is formed in order to facilitate the cleaning of the inside of the water tank 21.

However, while integrating the lower lid (C2) with the bucket 21, the upper inlet (I _U ) and the lower lid (C2) may be expanded to facilitate the internal cleaning of the bucket (21).

As described above, the upper water supply humidifier of the present invention, the valve to block or allow the flow of water in the water tank supplied to the atomization tank, by using a floating valve rather than an electronic automatic valve to prevent or minimize the failure rate of the valve The durability of the humidifier itself is improved, and the repair cost in case of valve failure is reduced, and the combined structure of the water inlet and sealing member enables the humidifier to operate normally without overflow of water even when the lid of the water tank is opened. It has the advantage of injecting water.
