The present invention relates to a steam thaw of a new method that does not require a separate storage tank for storing water, and is made of a pipe (pipe) by supplying water by using a pump to the steam generating tube is inserted into the heater is coupled to the inside , By heating only a small amount of water to generate steam.

2 is a view schematically showing a steam thawing apparatus according to an embodiment of the present invention.

2, the steam thawing apparatus 10 according to an embodiment of the present invention is a housing 20, steam generating pipe 30, the heater 40, the pump 50 and the heater 40 and the pump ( And a controller 60 that controls the operation of 50.

The housing 20 is configured to form the appearance of the steam thaw 10, and includes a lower case 22 having various components and an upper case 24 detachably coupled to the lower case.

The steam generating pipe 30 has a configuration in which a small amount of water is accommodated therein, is provided in the housing 20, has a pipe shape in which one side is opened, and the heater 40 is formed at the opened side. Is inserted and sealed is provided with a water supply port 32 for supplying water to the sealed interior, and a steam outlet 34 for discharging the steam generated by the water supplied to the sealed interior is heated by the heater 40 is provided. do.

In addition, the steam generating pipe 30 may be provided horizontally or vertically in the housing 10, preferably as shown in Figure 2 by a predetermined angle beveled by a support member 26 different in height from each other. It may be provided. Detailed description thereof will be described later.

The heater 40 is inserted and coupled to the steam generating pipe 30 to heat the water supplied to the steam generating pipe 30 to generate steam, is inserted into the steam generating pipe 30 by screw coupling Can be combined. The heater 40 may include a body part 42 and a heating part 44. After the heating part 44 is inserted into the steam generating pipe 30, the body part 42 is a steam generating pipe ( 30) may be coupled to the steam generating pipe 30 by screwing. In addition, as described above, one side of the steam generating pipe 30 may be opened to allow the heater 40 to be inserted, and the other side may be configured to be blocked, and the body portion 42 of the heater 40 is closed. ) And the steam generating pipe 30 corresponds to each other in size so that the screw can be coupled to each other, the outer surface of the body portion 42 and the inner surface of the steam generating pipe 30 to be formed with a thread corresponding to each other Can be. Therefore, the steam generating pipe 30 can be sealed by the coupling with the heater 40.

The pump 50 is a configuration for supplying external water to the steam generating pipe 30, the inside of which is sealed by the coupling with the heater 20, is provided in the housing 20 and the water ball of the steam generating pipe 30 It is connected to the supply port 32. That is, the steam thawing apparatus 10 according to the present invention is not provided with a separate storage tank for storing water, but only a small amount of water for generating steam from the outside by the pump 50. ) Is supplied.

Therefore, since the steam thawing machine 10 according to the present invention does not need a separate storage tank, the size can be made small, and since the water is supplied to the steam generating pipe 30 only to generate steam by the pump 50, the steam can be rapidly steamed. It is possible to generate, and the amount of water that needs to be heated to generate steam can save energy, thereby improving the efficiency. In addition, since a small amount of water is directly heated to generate steam, it is possible to generate steam quickly and smoothly, and there is no need for a user to inject water directly, and there is no risk of burns.

In addition, the steam thawing machine 10 according to an embodiment of the present invention is connected to the steam outlet 34 of the steam generating pipe 30 to the steam generated in the steam generating pipe 30 to the outside of the housing 20 It may further comprise a steam discharge pipe 70 for discharging, and a water supply pipe 80 for connecting the water outside the housing 20 and the pump 50.

In addition, although not shown in the drawings, the heater 40 and the pump 50 may be connected to the controller 60 by a plurality of wires or the like to be controlled by the controller 60, the steam thawing machine according to the present invention 10 may further include an operation unit provided with a plurality of buttons so that the user can select the operation of the heater 40 and the pump 50.

On the other hand, since the steam generating pipe 30 according to the present invention can accommodate only a small amount of water, the controller 60 is the pump 50 so that the amount of water supplied to the steam generating pipe 30 can be properly maintained It is desirable to control the operation of.

To this end, the steam thawing machine 10 according to an embodiment of the present invention is provided at a predetermined position of the steam generating pipe 30 further comprises a sensor 90 for detecting the temperature of the steam generating pipe 30 The controller 60 may be provided to control the operation of the pump 50 according to the detection of the sensor 90. The sensor 90 may be used in any form for detecting the temperature of the steam generating tube 30, preferably a resistance change type sensor for measuring the temperature in accordance with the change in the measured resistance value.

In general, when water is insufficient in the steam generating pipe 30, the temperature of the steam generating pipe 30 is raised, on the contrary, when water is overflowed in the steam generating pipe 30, the temperature of the steam generating pipe 30 is lowered. I will go. Therefore, by sensing the temperature of the steam generating pipe 30 it is possible to determine whether to supply more water to the steam generating pipe 30 or to reduce the supply of water. For example, when the temperature sensed by the sensor 90 is greater than or equal to a preset temperature, the controller 60 determines that the water is insufficient in the steam generating pipe 30 and operates the pump 50 to operate the steam generating pipe ( It is possible to control the water to be supplied to 30 or increase the amount of water supplied to the steam generating pipe 30 by increasing the operating speed of the pump 50. On the contrary, if the temperature sensed by the sensor 90 is less than or equal to a preset temperature, the controller 60 determines that water is overflowing in the steam generating pipe 30 and stops the operation of the pump 50 to supply water. By blocking or reducing the operating speed of the pump 50 may be controlled to reduce the amount of water supplied to the steam generating pipe (30).

Preferably, as shown in Figure 2, the sensor 90 may be provided at a position corresponding to the appropriate water level (W) of the water contained in the steam generating pipe (30). As such, when the sensor 90 is provided at a position corresponding to the proper water level (W), the controller 60 operates the pump 50 so that the water level of the steam generating pipe 30 always maintains the proper water level. Can be controlled. For example, the controller 60 determines that the water level of the water contained in the steam generating pipe 30 is received above the proper water level (W) when the temperature sensed by the sensor 90 is lower than or equal to a preset value. ) To stop the operation or to reduce the operating speed, on the contrary, if the temperature detected by the sensor 90 is higher than the preset value, the water level of the water contained in the steam generating pipe 30 is accommodated below the proper water level (W). By determining that the pump 50 is operated or the operating speed is increased, the water level of the water contained in the steam generating pipe 30 can be controlled to maintain the proper water level (W) at all times.

In another embodiment, the steam thawer 10 according to an embodiment of the present invention may be provided so that the controller 60 controls the operation or operating speed of the pump 50 according to the strength of the heater 40. For example, an operation unit is provided to allow a user to select the intensity of the heater 40 without the sensor 90 being provided, and the controller 60 operates in response to the intensity of the selected heater 40. The pump 50 can be controlled to operate at a speed. In fact, the amount of water to be supplied to the steam generating pipe 30 is determined by the strength of the heater 40. That is, since the amount of generated steam changes according to the strength of the heater 40 and accordingly the required amount of water contained in the steam generating pipe 30 changes, the amount of water to be supplied to the steam generating pipe 30 by the pump 50 also changes. do. Therefore, the operation speed of the pump 50 corresponding to the strength of the heater 40 is preset in consideration of the size of the steam generating pipe 30, and the controller 60 presets the operation according to the strength of the selected heater 40. If the pump 50 is controlled to be operated at a speed, even if a separate sensor 90 is not provided, it can be controlled so that an appropriate amount of water can always be supplied into the steam generating pipe 30.

On the other hand, the steam outlet 34 is preferably provided on the upper portion of the steam generating pipe 30 so that the generated steam can be discharged smoothly, the water supply port 32 is the steam generated is the steam outlet 34 It is preferable that it is provided in the lower portion of the steam generating pipe 30 so as not to interfere with the discharge through. The water supply port 32 is kept open even when steam is generated because water must be continuously supplied from the pump 50, and thus, the water supply port 32 is provided if the water supply port 32 is provided above the steam generating pipe 30. This is because a problem such as contact with the generated steam or the generated steam is introduced into the water supply port 32 may occur.

In addition, when the water supply port 32 is provided below the steam generating pipe 30, the water contained in the steam generating pipe 30 may flow back to the pump 50 through the water supply port 32. Therefore, the pump 50 is preferably a backflow prevention pump.

Hereinafter, the operation of the steam thaw 10 according to an embodiment of the present invention will be described briefly.

First, a user connects a nozzle or a hose inserted into a pipe to be thawed to a steam discharge pipe 70, and connects external water to a water supply pipe 80 using a predetermined supply hose. Here, the external water may be water provided from the tap, or may be water stored in a tank located outside.

Thereafter, the user only presses the operation button provided in the controller 60 to operate the pump 50 and the heater 40, and the external water is supplied to the pipe 30 by the pump 50 and is simultaneously supplied. Steam generated quickly by the heater 40 is discharged to the outside through the steam discharge pipe (70). Then, water is automatically supplied by the controller 60 to generate steam.

Hereinafter, a steam thawing apparatus according to another embodiment of the present invention will be described in detail. However, in the description of the steam thawing apparatus according to the present embodiment, the description of the same configuration as the steam thawing apparatus according to the embodiment will use the description in the above embodiment, and the same reference numerals refer to the same numbers. use.

3 is a perspective view showing a steam thaw according to another embodiment of the present invention, Figure 4 is a view schematically showing the interior of the steam thaw according to Figure 3, a view showing a state in which the upper case is removed.

3 and 4, the steam thaw 100 according to the present embodiment is the housing 20, the steam generating pipe 30, the heater 40, the pump 50, the controller 60 as in the embodiment ), The steam discharge pipe 70 and the water supply pipe 80 may be made.

In addition, the steam thaw 100 according to the present embodiment prevents the heat generated from the first sensor 110, the steam generating pipe 30 to detect the temperature of the steam generating pipe 30 to the controller 60. Blocking membrane 120, the heat shield cover 130 to prevent the heat generated in the steam generating pipe 30 is transmitted to the outside, the heat shield is provided on the top of the heat cover 130, overheating the steam generating pipe 30 It may further comprise a second sensor 140 for detecting the.

The first sensor 110 corresponds to the sensor 90 in the embodiment, the sensor 90 in the embodiment is provided at a position corresponding to the appropriate water level (W) of the steam generating pipe (30) Unlike being provided is provided on one side of the steam outlet 34 of the steam generating pipe (30). In practice, since the temperature of the steam generating pipe 30 is very high, it is not preferable that the first sensor 110 for detecting the temperature of the steam generating pipe 30 is directly provided in the steam generating pipe 30, and the present embodiment. As in the example, it is preferable to be provided at one side of the steam outlet 34 of the steam generating pipe 30. In addition, even if provided in the steam outlet 34, the operation of the pump 50 by the controller 60 for supplying water to the steam generating pipe 30 can be made smoothly.

The blocking film 120 is provided between the controller 60 and the steam generating pipe 30 to prevent heat generated in the steam generating pipe 30 from being transferred to the controller 60. The controller 60 is configured to control the operation of the heater 40 and the pump 50, and the like, since various components such as a circuit board and a semiconductor element are provided. It is necessary to protect from heat, and therefore, the blocking film 120 is preferably provided.

The heat shield cover 130 is provided to cover a predetermined portion of the steam generating pipe 30 at a predetermined interval to prevent the heat generated from the steam generating pipe 30 to be transferred to the housing 20. Since the heat generated from the steam generating tube 30 during operation is very high, such a heat may be burned by the user when the heat is transferred to the housing 20, and thus, the risk of such burns is prevented by providing the heat shield cover 130. It is preferable to.

The second sensor 140 is provided on top of the heat shield cover 130 to sense overheating of the steam generating pipe 30, and like the first sensor 110, a sensor for sensing a temperature, preferably measuring A resistance change sensor that measures temperature according to the changed resistance value can be used.

Since the steam generating pipe 30 has a configuration in which the heater 40 is inserted therein and the supplied water is heated to generate steam, the heater 40 is overheated or the steam generating pipe ( If water is not supplied to 30, the steam generating pipe 30 may be overheated, in which case it is necessary to stop the operation.

Therefore, the steam thawing apparatus 100 according to the present exemplary embodiment includes a second sensor 140 on an upper portion of the heat shield cover 130 and the controller 60 when the temperature detected by the second sensor 140 is higher than or equal to a preset temperature. The steam generating pipe 30 is overheated, that is, the heater 40 may be overheated or the pump 50 may be judged to be abnormal in operation so that all the operations are stopped.

In addition, one side of the housing 20 of the steam thawing apparatus 100 according to the present embodiment, various lamps 101 indicating an operating state, the operation unit 104 is provided so that the user can select the strength or the amount of steam generated by the heater 40 , The power switch 102, the power line 103, the water supply hose 105 connected to the water supply pipe 80, the steam discharge hose 106 connected to the steam discharge pipe 70 may be provided, the housing ( The upper portion of the 20 may be provided with a handle portion 107 to facilitate transportation.

In fact, since the steam generation amount is determined by the strength of the heater 40, the user's selection by the operation unit 104 may be a selection of the strength or the steam generation amount of the heater 40, so that only the content displayed on the operation unit 104 is determined. There will only be a difference whether it is indicated by the intensity of the heater 40 or by the amount of steam generated.

In addition, as described above, the controller 60 controls the heater 40 according to the amount of steam selected by the operation unit 104 or the strength of the heater 40, and the amount of steam selected by the operation unit 104 or The pump 50 may be controlled to operate according to a preset value corresponding to the strength of the heater 40 or the pump 50 may be operated according to the detection of the first sensor 110.

Hereinafter, a preferred embodiment in which the steam generating tube is provided in the housing will be described in detail with reference to FIGS. 5 to 7.

5 to 7, the steam outlet 34 of the steam generating pipe 30 is located between the body portion 42 and the heating portion 44 of the heater 40, that is adjacent to the body portion 42 It is preferable that the steam outlet 34 is located directly on the upper portion of the heating part 44. In addition, because water can also be introduced together is not preferable.

First, as shown in Figure 5, when the steam generating pipe 30 is provided in a horizontal state, the water level (W) of water that can be accommodated in the steam generating pipe 30 is the heating portion 44 of the heater 40 It is possible to cover all of them to maximize the contact area between the water and the heating unit 44, but in this case the water heating by the heating unit 44 because the inner space 36 is made very narrow horizontally long When the water 튐 phenomenon is very severe, there is a problem that the worry that the water is discharged with the steam to the steam outlet 34 becomes larger, and also the steam outlet 34 toward the body portion 42 of the heater 40 Since it is located in a biased position, steam generated far from the body part 42 is not easily discharged to the steam outlet 34.

Next, as shown in Figure 6, when the steam generating pipe 30 is provided in a vertical state, the water level (W) of the water in the steam generating pipe 30 so that the water does not flow into the steam discharge port 34 Since it must be lower than (34), there is a problem that a relatively large portion of the heating section 44 that is not in contact with the water is present to minimize the contact area between the heating section 44 and the water, and there is also a problem that the overall size increases. .

Therefore, as shown in Figure 7, the steam generating pipe 30 is preferably provided at a predetermined angle beveled, if the steam generating pipe 30 is provided at an angle at a predetermined angle, that is, the same problem as the above It is preferable to solve the problem of the space 36 being horizontal, the problem of the contact area between the heating part 44 and water, and the problem of increasing the overall size.

In fact, according to the experiments of the present inventors, it is confirmed that the steam generating tube 30 is most effective when provided at an angle of about 10 ° and is capable of smooth steam generation and steam discharge. In particular, when the steam generating pipe 30 is provided in a vertical or horizontal state, water is discharged together with the steam discharge, but when the steam discharge pipe 30 is provided at an angle of about 10 °, the water is almost discharged. It was confirmed that it was not discharged.

Therefore, the steam generating tube 30 according to the present invention is preferably provided at an angle at a predetermined angle in the housing 20, and more preferably at an angle of about 10 degrees.

On the other hand, as described above, the steam thawing machine (10,100) according to the present invention is a steam generating pipe 30 and only a small amount of water for generating steam and the steam generating pipe 30 is inserted into the steam generating pipe ( Heater 40 to heat the water contained in the 30 to generate steam, and a pump 50 for supplying the external water to the steam generating pipe 30 is made, a separate storage tank for storing water It is possible to make the size small because it is not necessary and the amount of water to be heated to generate steam is characterized in that it can generate steam quickly, efficiently and smoothly, the embodiment can be changed into various forms something to do. Therefore, the present invention is not limited to the embodiments disclosed in the present specification, and all forms changeable by those skilled in the art to which the present invention pertains will belong to the scope of the present invention.

Since the steam thawing machine according to the present invention does not need a storage tank for storing water separately, it can be made small in size, so that the user can easily carry or transport the steam thaw, and the amount of water to be heated to generate steam is fast. Since it is possible to generate steam, and to supply steam efficiently and smoothly, it is expected to give a lot of convenience in operation, and thus its use is expected to be increased.
