Description

[0001] APPARATUS OF PRODUCING CARBONATED WATER [0002]

TECHNICAL FIELD The present invention relates to a carbonated water producing apparatus, and more particularly, to a carbonated water producing apparatus using a microwave.

Generally, a carbonated water producing apparatus provided in a refrigerator or a water purifier has a fuel tank containing carbon dioxide.

That is, a carbonated water producing apparatus having a fuel tank is a technique for producing carbonated water by injecting carbon dioxide in a high pressure state in a fuel tank into a dedicated water bottle.

Such a fuel tank type carbonated water producing apparatus is applicable to appliances such as a refrigerator and a water purifier. When carbon dioxide water is periodically charged into the fuel tank, the user can produce carbonated water safely in a short time within the home or company.

However, in the fuel tank-type carbonated water producing apparatus, when the carbon dioxide contained in the fuel tank is exhausted, it is inconvenient to replace the fuel tank or inject carbon dioxide into the fuel tank. Particularly, there is a problem that replacement of the fuel tank or injection of carbon dioxide into the fuel tank is difficult to be performed by a general user of the carbonated water producing apparatus.

In addition, fuel tanks for storing carbon dioxide are expensive to manufacture and require extreme care in transporting the fuel tanks due to their high weight and high internal pressure.

As another type of the carbonated water producing apparatus, unlike the fuel tank type carbonated water producing apparatus, there is a chamber type using a microwave heat source.

Unlike the carbonated water producing apparatus of the fuel tank type, the chamber-type carbonated water producing apparatus can be provided with a composition capable of generating carbon dioxide, for example, sodium hydrogencarbonate, without a fuel tank for storing carbon dioxide.

The chamber type carbonated water producing apparatus can produce carbonated water by applying microwave to a specific composition at a high spinning speed to generate carbon dioxide and injecting the generated carbon dioxide into a water bottle.

On the other hand, in such a chamber-type carbonated water producing apparatus, the heating frequency of the microwave applied to the composition can be determined according to the size of the chamber. In the case where microwave is applied to the composition, it is necessary to design the chamber so that the volume of the chamber becomes a specific value or more in order to generate carbon dioxide, which causes a problem that the volume of the carbonated water producing apparatus is excessively increased.

In addition, as compared with the fuel tank type carbonated water producing apparatus, the chamber type carbonated water producing apparatus has a problem that the rate of generating carbon dioxide is slow.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a carbonated water producing apparatus capable of solving the above problems, and a carbonated water producing apparatus, particularly a chamber type carbonated water producing apparatus, .

Another object of the present invention is to provide a device for producing carbonated water capable of lowering the heating frequency of a microwave for a composition.

The present invention also provides a device for producing carbonated water capable of increasing the rate of generation of carbon dioxide.

In order to solve the above-mentioned problems, the present invention discloses a carbonated water producing apparatus including a reduced-volume chamber.

Specifically, the chamber-type carbonated water producing apparatus may include a receiving portion formed in at least a part of the chamber to receive a composition for producing carbon dioxide.

Such a receptacle may be provided with a capsule-shaped composition for easy replacement.

The apparatus for producing carbonated water according to the present invention may further comprise a microwave generator for generating microwaves for transferring heat to the composition housed in the receiver, a controller for applying the microwaves to the composition to control the microwave generator to generate carbon dioxide, . ≪ / RTI >

In particular, according to one embodiment, a dielectric may be provided in at least a portion of the interior region of the chamber. The interior region of the chamber may correspond to a space defined by the chamber and the bottom surface of the receiving portion. Further, the dielectric may be substantially entirely filled in the inner region of the chamber, or may be filled in only a portion of the inner region of the chamber.

According to one embodiment, the control unit can control the microwave generating unit based on information related to the dielectric constant of the dielectric. That is, the carbonated water producing apparatus can store information related to the dielectric constant of the dielectric, and the control unit can control the microwave generating unit based on the stored information. On the other hand, information related to the dielectric constant of the dielectric may be sensed by a sensor installed inside the chamber, or may be directly input by a user.

According to one embodiment, the control unit can reduce the frequency of the microwave when the dielectric constant of the dielectric provided inside the chamber increases.

According to one embodiment, the volume of the chamber can be determined based on the dielectric constant of the dielectric.

According to one embodiment, as the dielectric constant increases, the volume of the chamber can be reduced.

According to one embodiment, the dielectric may be formed of an object that reduces the heating frequency for generating carbon dioxide in the composition.

According to one embodiment, the dielectric may be formed of an object that prevents the generation of sparks in the microwave generating part.

In one embodiment, it may further comprise a tuner that matches the output impedance of the microwave with the load impedance of the composition.

In one embodiment, the dielectric may be provided in a portion of the interior region of the chamber.

In one embodiment, the tuner may be formed inside the chamber, and one surface of the tuner may form a curved surface positioned between the microwave generator and the composition.

In one embodiment, the control unit controls the microwave generating unit based on information related to the specification of the chamber.

According to the present invention, it is possible to reduce the volume of the carbonated water producing device, so that the carbonated water producing device according to the present invention can be easily installed inside other devices such as a refrigerator and a water purifier.

In addition, since the apparatus for producing carbonated water according to the present invention includes a chamber formed with a reduced volume, its manufacturing cost can be reduced.

Further, according to the present invention, it is possible to provide a carbonated water producing apparatus with reduced volume while maintaining the capability of generating carbon dioxide.

The invention disclosed in this specification can be applied to a carbonated water producing apparatus and a control method of a carbonated water producing apparatus. However, the invention disclosed in this specification is not limited thereto, and can be applied to all existing carbonated water production apparatuses, control apparatuses thereof, control method of carbonated water production apparatuses, and miniaturization methods of carbonated water production apparatuses to which the technical idea of the present invention can be applied .

It is noted that the technical terms used herein are used only to describe specific embodiments and are not intended to limit the scope of the technology disclosed herein. Also, the technical terms used herein should be interpreted as being generally understood by those skilled in the art to which the presently disclosed subject matter belongs, unless the context clearly dictates otherwise in this specification, Should not be construed in a broader sense, or interpreted in an oversimplified sense.

Also, the singular forms "as used herein include plural referents unless the context clearly dictates otherwise. In this specification, the terms "comprising ", or" comprising ", etc. should not be construed as necessarily including the various elements or steps described in the specification, Or may be further comprised of additional components or steps.

In the following FIG. 1A, an embodiment of a general carbonated water producing apparatus will be described.

1B, an embodiment related to a heating pattern of a microwave applied to the composition of the carbonated water producing apparatus shown in FIG. 1A will be described.

As shown in FIG. 1A, a chamber-type carbonated water producing apparatus may include a chamber 110 and a receiving portion 130 formed on the upper portion of the chamber 110 to receive a composition for producing carbon dioxide.

In addition, the chamber-type carbonated water producing apparatus includes a microwave generating unit 120 for generating a microwave. As the generated microwave is applied to the composition accommodated in the receiving unit 130, carbon dioxide is generated.

When any composition is heated to a temperature above the characteristic temperature of the composition, the composition may be degraded. The characteristic temperature may be a pyrolysis temperature defined for any composition. That is, when an arbitrary composition receives a certain amount or more of heat, the composition may make a phase shift.

For example, when a certain amount or more of heat is applied to sodium bicarbonate, the sodium hydrogencarbonate decomposes and can release carbon dioxide.

When the composition (for example, sodium hydrogencarbonate) is heated using the microwave heating source as described above, the heating pattern of the microwave applied to the receiving portion 130 may vary according to the size of the chamber 110.

More specifically, referring to the heating pattern of the composition or storage unit 130 shown in FIG. 1B, the controller of the carbonated water producing apparatus controls the microwave generating unit (not shown) so that the heat applied to the central portion of the receiving unit 130 is larger than the peripheral portion. 120).

For reference, the heating frequency associated with the heating pattern of the accommodating portion 130 can be determined based on the following equation (1).

The control unit 280 may control the microwave generating unit 220 so that the frequency of the microwave applied to the center of the receiving unit 130 is lower than the heating frequency derived by Equation 1. [

Figure pat00001

Where m and n are positive integers, a is the first length of the chamber 110, and b is the second length of the chamber 110. In the equation (1), f is the heating frequency in the receiver 130, .

For example, when the chamber 110 is formed into a rectangular parallelepiped, a and b may correspond to the transverse length and the longitudinal length of the chamber 110, respectively.

In order to generate carbon dioxide in the carbonated water producing apparatus, the frequency of the microwave may be set to a specific value or less, and in order to derive a frequency corresponding to a specific value in Equation (1), a parameter related to the volume of the chamber 110 a, b can be adjusted.

That is, in the carbonated water production apparatus, the width, length, or height of the chamber can be designed to a specific value in order to set an appropriate frequency level of the microwave.

For example, when m and n are both 1 in Equation 1, the width of the chamber 110 may be 86 mm, the length 86 mm, and the height 130 mm.

Since the carbonated water producing apparatus including the designed chamber 110 has a large volume, it is inadequate to be disposed inside the refrigerator or the water purifier.

That is, in many cases, it is used in combination with other devices such as a refrigerator and a water purifier as an embodiment in which a carbonated water producing device is used at home, but there is a need to reduce the volume of the carbonated water producing device for coupling with other devices .

Therefore, in the following description, embodiments for providing a chamber-type carbonated water producing apparatus formed with a relatively small volume will be described.

The receiving portion 230 may be formed on one side of the chamber 210. Specifically, the receiving portion 230 may be a concave portion formed on one surface of the chamber 210.

The receiving portion 230 can accommodate a composition that generates carbon dioxide. That is, the receiving portion 230 can accommodate a composition composed of a capsule.

In this case, the composition may be sodium hydrogencarbonate, or may be a substance that generates carbon dioxide upon heating.

The receiving portion 230 may include a first cap 240. The first cap 240 can open and close one side of the receiving portion 230. In particular, after the composition is received in the receiving portion 230, the first cap 240 may close one side of the receiving portion 230 to seal the inside of the receiving portion 230.

One end of the hose 201 is connected to the first cap 240 and the other end of the hose 201 is connected to the second cap 206 which opens or closes the blowing unit 202 or the blowing unit 202 have.

Specifically, the control unit 280 can control the microwave generating unit 220 based on information related to the dielectric constant of the dielectric material existing in the chamber 210.

In one example, the carbonated water producing device may further include a memory (not shown), which may store information related to the dielectric constant of the dielectric.

In one example, the carbonated water producing apparatus may include at least one sensor inside the chamber 210, and may sense information related to the dielectric provided inside the chamber 210 from the at least one sensor. Such sensed information can be stored in memory.

In one example, the carbonated water production apparatus may further include an input unit (not shown) to which a user input is applied, and the input unit may receive a user input including information related to a dielectric constant of the dielectric.

The control unit 280 may control the micro-generator 220 so that the frequency of the microwave decreases when the dielectric constant of the dielectric provided in the chamber 210 increases.

In contrast, if the dielectric constant of the dielectric provided in the chamber 210 is decreased, the control unit 280 may control the micro-generator 220 to increase the frequency of the microwave.

The control unit 280 may control the microwave generating unit based on information related to the specification of the chamber 210. For example, if the chamber 210 is a rectangular parallelepiped, the information associated with the dimensions of the chamber 210 may include information relating to at least one of the width, height, and height of the chamber 210. Information related to the specification of the chamber 210 may be obtained from the user.

The tuner unit 270 may be connected to the control unit 280 to receive a control signal for matching the load impedance of the composition from the control unit 280. [

On the other hand, the tuner unit 270 measures the phase and amplitude of the load itself without being controlled by the control unit 280, and based on the error signal corresponding to the difference, The impedance may be changed to match the input impedance.

In the case where the tuner unit 270 performs impedance matching separately from the control unit 280, the tuner unit 270 includes an impedance sensor (not shown) for measuring the phase and magnitude of the load impedance of the composition, And a matching circuit (not shown) for performing impedance matching.
