Description

High efficiency heating type humidifier

The present invention relates to a heater-type humidifier, and more particularly, to a high-efficiency heater-type humidifier that can maximize energy efficiency by improving the problem of high power consumption, improve safety, and facilitate sediment treatment.

A humidifier is an electric appliance that controls indoor humidity by discharging water vapor, and consists of an ultrasonic type, a heater type, a natural vaporization type, and a complex type.

Among them, the heater type humidifier is very hygienic because it can be sterilized and sterilized in that it boils water and evaporates vaporized water, and has the advantage of warming the surroundings at the same time.

On the other hand, since it is a method of boiling water, there is a disadvantage that there is a risk of burns due to high temperature steam and high power consumption.

As a technique for improving these shortcomings, Patent Document 1 discloses a safety control method and an apparatus for a heater humidifier.

The invention of Patent Document 1 consists of a human body detection sensor that is installed around the spout to change the proximity of the human body into an electrical signal, and a field effect transistor and several resistors selectively driven according to the output voltage of the human body detection sensor. When the human body is within a predetermined distance from the heater humidifier, a human body detection unit that generates a predetermined output signal to the microcomputer is added to the existing heater humidifier, and if there are people around the heater humidifier, the microcomputer in the control unit blocks the operation of the heater and the blower. By giving, it is characterized in that it prevents in advance from being burned to the hand or face due to hot water vapor.

However, since the prior art operates only when a human body is not detected within a predetermined distance around the humidifier, it may be difficult to continuously humidify depending on whether or not a person is approached, and it is necessary to install a predetermined distance apart from the human body. There is a problem to bring.

Patent Literature 2, which is the background technology of the present invention, discloses a method of reducing power consumption of a heater-type humidifier to improve the problem of high power consumption.

The invention of Patent Document 2 is the first step of determining the dry water to check the water in the bucket after power-on by the humidifier switch, the second step of starting the initial preheating by driving the heater driver when it is determined that there is water in the dry water determination step. , The third step of integrating the time using the output signal of the heater driver and then comparing it with the time set in advance to a predetermined value, and if the compared time is determined to be more than that, the water molecule heated by the blower fan is The fourth step of humidifying and discharging, and the fifth step of detecting the water in the bucket when water is supplied through the water inflow detection unit during the above step and increasing the output of the heater driving unit, and the load driving unit at the same time as the fifth step is performed. It consists of a sixth step of driving control to lower the output of the blowing fan motor.

The invention of Patent Document 2 is characterized in that the blowing fan is driven after the heating time has elapsed, while the temperature in the water tank is rapidly increased and controlled.

The invention of Patent Document 2 has the effect of reducing power consumption by controlling the operating time by appropriately adjusting the fan motor and the heater when the initial heating or when water from the water tank flows into the water tank.

However, since the heater operating time is inevitably longer since the entire water in the water tank is heated, there is a limit to reducing power consumption by reducing the operating time.

In addition, since the heater-type humidifier generates sediment due to mineral components in the water used, there is a problem that the conventional heater-type humidifier is structurally difficult to treat the precipitate.

1 to 4, the present invention includes a case part 100, a heating part 200, and a steam flow part 300.

Hereinafter, the present invention will be described in detail based on the above components.

The case part 100 is a component that forms the main body of the high-efficiency heater type humidifier of the present invention, and includes an upper case 130 and a lower case 150.

The upper case 130 has a printed circuit board and various electrical components embedded therein, and various buttons for operating the humidifier and a display for displaying functions may be formed on the outer surface thereof.

In addition, an outlet 131 through which steam evaporated by the heating unit 200 is discharged is provided at one side of the upper case 130, and a suction port for inflow of external air is provided at the other side of the upper case 130. 132) may be further provided.

In addition, a blowing means 133 including a blowing fan and a motor for sucking external air through the inlet 132 and sending it to the outlet 131 may be provided inside the inlet 132.

This is to reduce the risk of burns due to water vapor discharged from the outlet 131 by mixing high-temperature water vapor generated by evaporation from the lower case 150 with cold outside air to lower the temperature of the water vapor.

In addition, a seating portion 134 protruding inwardly and formed in a plate shape and having a first flow hole 134a formed in the center of the lower portion of the upper case 130 is provided, and a fastening means is inserted into the seating portion 134 A fastening hole (not shown) is formed so that the heating unit 200 can be fixedly coupled to the upper case 130 through this.

Here, water vapor generated by the heating unit 200 passes through the first flow hole 134a.

The lower case 150 is configured to provide a space for storing water, and the upper part is opened to be detachably coupled to the upper case 130, and any means for enabling such coupling may be applied. In the embodiment, a screw is formed on the upper outer circumferential surface of the lower case 150 and a screw is formed on the lower inner circumferential surface of the upper case 130.

In addition, it is preferable that the lower case 150 is made of a transparent material so that the user can directly check the amount of water stored therein.

The heating unit 200 is a component for heating a portion of water stored in the lower case 150, and includes a heat shield pipe 230, a heater 250, and a connection support 270.

The heat shield pipe 230 is made of a material having a low thermal conductivity, and when the water inside the heat shield pipe is heated by the heater 250, the heat shield pipe 230 is a configuration that prevents the heat from being transferred to the outside in the radial direction of the heat shield pipe 230 as much as possible. As, a hollow pipe portion 231 having a predetermined thickness and length and a flange portion 233 extending at one end of the hollow pipe portion 231, and a fastening means such as a bolt is inserted into the flange portion 233 A plurality of first fastening holes 235 are formed.

Here, the thicker the thickness of the hollow pipe part 231 is, the less heat transfer may be made to be effective, but the appropriate thickness is selected in consideration of the arrangement relationship with the heater 250 installed inside the heat shield pipe 230, workability, and economy. It is desirable.

The heater 250 is provided inside the heat shield pipe 230, has a predetermined length, but has a hollow heating element support 251, and a heating element 253 that is built in the lower portion of the heating element support 251 to generate heat. ), and a pair of cables 255 connected to the heating element 253 and electrically connected to the power supply unit.

The lower end of the heater 250 is installed to be positioned above the lower end of the heat shield pipe 230 by a predetermined depth h.

In terms of efficiency, it is preferable to select the predetermined depth h to a degree to secure at least a part of the lukewarm water region B, which will be described later.

As the heat shield pipe 230 and the heater 250 are configured in this way, the water heated by the heater 250 is limited to the water inside the heat shield pipe 230, not the entire cold water stored in the lower case 150. .

More specifically, as shown in FIG. 3, when the heater 250 is heated, a hot water region A in which hot water is present is formed inside the heat shield pipe 230 in which the heater 250 is disposed. As a result, a lukewarm water region (B) in which a certain amount of hot and cold water is mixed is formed inside the heat shield pipe 230 corresponding to the predetermined depth (h), and between the outside of the heat shield pipe 230 and the lower case 150 A cold water region C in which water is present is formed.

The reason why water can be distributed to the hot water region A, the lukewarm water region B, and the cold water region C is due to the configuration of the heat shield pipe 230.

That is, even if the water inside the heat shield pipe 230 is heated by the heater 250, heat transfer from the inside of the heat shield pipe 230 in the radial direction to the outside hardly occurs, and the heated water tries to move to the upper floor, so that the hot water region ( In A), only hot water with a lower density exists, and in the lukewarm water region (B) below the lukewarm water region (B), lukewarm water is present by mixing a certain amount of hot water and cold water, and the cold water region outside the heat shield pipe 230 ( In C), only cold water with high density exists because heat by the heater 250 is not transferred.In the heat shield pipe 230, a general convection phenomenon that occurs when hot water is at the bottom and cold water is at the top. It doesn't happen.

Due to this, the high-efficiency heater type humidifier of the present invention enables intensive heating and evaporation in the hot water area (A), so that even with a small heater and low power consumption, it is possible to secure performance over existing products.

On the other hand, while using a conventional heater type humidifier, if the humidifier is inverted, hot water may leak to the outside and cause burns, but in the present invention, the humidifier in operation may be inverted and the stored water in the lower case 150 is Even if it leaks out, the safety of the heater-type humidifier is increased because the risk of burns can be reduced because hot water inside the heat shield pipe 230 and the cold water outside the heat shield pipe 230 are mixed and lukewarm water leaks out during the conduction process. do.

As shown in FIG. 4, the connection support part 270 is a configuration for fixedly coupling the heat shield pipe 230 and the heater 250 to the case part 100, and consists of a support plate 280 and a support base 290. .

The support 290 is integrally formed with a hollow connection support pipe 291 and one end of the connection support pipe 291 to which one end of the heating element support 251 is inserted and fixed therein, and the support plate 280 and It consists of a connection support plate 293 configured in a corresponding size.

The connection support plate 293 includes a plurality of third fastening holes 295 and a plurality of third fastening holes 295 at positions corresponding to the plurality of second fastening holes 281, the second insertion holes 283, and the plurality of second flow holes 285. 3 insertion holes 297 and a plurality of third flow holes 299 are formed.

2 and 4, the flange portion 233 of the heat shield pipe 230 is coupled to the connection support plate 293 of the support 290, and the heating element support 251 of the heater 250 is the support 290 ) Is inserted and fixed in the connection support pipe 291, the support 290 is coupled to the support plate 280, and the support plate 280 is coupled to the seating portion 134 of the upper case 130, thereby preventing the heat shield pipe ( 230) and the heater 250 are fixedly coupled to the upper case 130.

In this case, the mounting portion 134, the support plate 280, the support 290, and the heat shield pipe 230 may be coupled through fastening means such as bolts and nuts.

The steam flow unit 300 is a passage through which water vapor evaporated while the water inside the heat shield pipe 230 is heated by the heater 250 flows, and the first flow hole 134a of the seating portion 134, the support plate The second flow hole 285 of 280 and the third flow hole 299 of the support 290 are configured to communicate with the outlet 131 of the upper case 130.

Meanwhile, when the suction port 132 and the blowing means 133 are provided, a fluid mixing port 170 connecting the suction port 132 and the discharge port 131 inside the upper case 130 for lowering the temperature and smooth discharge of water vapor May be further provided.

The fluid mixing port 170 is formed in a hollow cylindrical shape with both sides open, one opening in the longitudinal direction is installed adjacent to the outlet 131 and the other opening is installed adjacent to the blowing means 133, and the lower part thereof A fourth flow hole (170a) is formed so as to communicate with the first flow hole (134a).

Thus, the evaporated high-temperature steam is sequentially passed through the third flow hole 299, the second flow hole 285, the first flow hole 134a, and the fourth flow hole 170a to the inside of the fluid mixing port 170. The water vapor is introduced, and the water vapor is mixed with the external air sucked by the blowing means 133 to lower the temperature of the water vapor, and the water vapor mixed through the flow path according to the shape of the fluid mixing port 170 is smoothly toward the discharge port 131 It becomes possible to flow.

On the other hand, FIG. 5 may further include a sediment treatment unit 400 for sediment treatment as another embodiment of the present invention.

The sediment treatment port 400 is installed detachably to the heat shield pipe 230, and is integrally connected to the bottom portion 430 and the bottom portion 430 having a plurality of grooves 430a formed on the upper surface thereof, and a plurality of flow holes (450a) consists of a vertical portion 450 formed around the periphery.

The concave groove 430a is a space in which sediment sinks and deposits, and by providing a storage space for sediment in the concave groove 430a, the sediment deposited at the bottom floats when cold water flows through the flow hole 450a. (浮遊) to prevent.

The flow hole (450a) is provided in a shape in which the diameter of the outer circumferential side of the vertical portion 450 is larger than the diameter of the inner circumferential side. It is difficult to flow out of the sediment treatment port 400.

In addition, it is preferable that the sediment treatment unit 400 is made of a transparent material so that the amount of sediment deposited in the groove 430a can be visually confirmed.

Accordingly, the humidifier user can easily determine the cleaning timing by checking the degree of sediment deposition.

And since the sediment treatment port 400 is coupled to the lower end of the heat shield pipe 230, it is possible to sufficiently secure a lukewarm water region B that can escape from the lower end of the heat shield pipe 230, so that the inside of the heat shield pipe 230 is more efficient. It can also play a role in enabling heating.

In addition, as shown in FIG. 5, a plurality of recovery holes 134b may be further provided on the seating portion 134 near the discharge port 131.

On the other hand, in the present invention, the operation of the humidifier can be controlled by additionally providing a sensor measuring the water level or a sensor measuring the temperature near the heating element 253 for efficient use of the humidifier.

In general, when a humidifier is manufactured according to its size or capacity, the internal structure of the humidifier is changed, and the compatibility of parts for each size or capacity decreases, which is inefficient in terms of manufacturing.

However, the high-efficiency heater type humidifier of the present invention only needs to change the size of the case part 100 without the need to change the size or structure of the heating part 200 when manufactured in small, medium, and large sizes, and in particular, the entire case part 100 By simply changing the size of the water storage space of the lower case 150, not changing the size of, it is possible to obtain the effect of purchasing and using a humidifier of a different size or capacity.

In other words, even a consumer who has purchased a small humidifier can purchase only the lower case with the capacity corresponding to the medium or large humidifier that can be combined with the upper case of the small humidifier and combine it with the upper case to be used like a medium or large humidifier. This is greatly augmented.

Although preferred embodiments of the present invention have been described above, various modifications may be made by those of ordinary skill in the art within the scope not departing from the spirit of the present invention.
