[0052] The present invention provides a steam generator 100.

[0053] Referring to Figures 1 to 3 Figures 1 to 3 , the steam generator 100 proposed by the present invention has an inlet 10a and an outlet 10b. The steam generator 100 includes a heating body 10, a pipeline assembly, and a valve assembly. The pipeline assembly includes a first pipeline 20, a first connecting pipe 40, a second pipeline 30, and a second connecting pipe 50 that are connected in sequence. The first pipeline 20 and the second pipeline 30 are arranged in the heating body 10. The first connecting pipe 40 is provided with the inlet 10a, and the second connecting pipe 50 is provided with the outlet 10b. The cross-sectional area of the pipeline of the first pipeline 20 is larger than the cross-sectional area of the pipeline of the second pipeline 30. The valve assembly is arranged on the first connecting pipe 40.

[0054] Among them, the first connecting pipe 40 and the second connecting pipe 50 can be arranged inside the heating body 10 to increase the heating efficiency, or can be arranged outside the heating body 10 to play a role in simplifying external connections.

[0055] The technical solution of the present invention is to adopt the first pipeline 20, the first connecting pipe 40, the second pipeline 30, and the second connecting pipe 50 arranged in the heating body 10. The first pipeline 20, the first connecting pipe 40, the second pipeline 30, and the second connecting pipe 50 are arranged between the inlet 10a and the outlet 10b to form a circulation loop. And, the opening degree of the first connecting pipe is controlled by the valve assembly. Since the cross-sectional areas of the pipelines of the first pipeline 20 and the second pipeline 30 are different, the vaporization speed of the liquid in the second pipeline 30 is greater than the vaporization speed of the first pipeline 20. Then, the opening degree of the first connecting pipe 40 is controlled by the valve assembly, so as to control the heating and gas outlet of the first pipeline 20 and the second pipeline 30, thereby increasing the gas discharge speed, thereby reducing the probability of scale formation, and further improving the use efficiency of the steam generator 100. Arranging the valve assembly on the first connecting pipe 40, that is, the liquid flow can be controlled at the inlet 10a, so as to achieve precise gas heating control.

[0056] Combined with reference to Figures 1 to 3 Figures 1 to 3 , in another embodiment of the present application, it can also be set as: the steam generator 100 further includes a first connecting pipe 40 and a second connecting pipe 50. The inlet 10a is arranged on the first connecting pipe 40, and the outlet 10b is arranged on the second connecting pipe 50; the first pipeline 20 and the second pipeline 30 are arranged in parallel and are both connected to the first connecting pipe 40 and the second connecting pipe 50.

[0057] With such arrangement, the external liquid can be vaporized through the first pipeline 20 and the second pipeline 30 at the same time. When vaporization is in progress, the external liquid first enters the first connecting pipe 40 through the inlet 10a, then enters the first pipeline 20 and the second pipeline 30 from the first connecting pipe 40 respectively to be vaporized, then merges into the second connecting pipe 50, and flows out from the outlet 10b of the second connecting pipe 50. In this way, the vaporization speed in the first pipeline 20 is fast, and the liquid flow rate in the second pipeline 30 is large. Through the parallel arrangement, the effect of step heating can also be achieved, and the overall liquid is heated faster, so that faster heating can be achieved and the gas discharge rate can be increased.

[0058] Furthermore, the valve body assembly further includes a first valve body 61 , which is disposed on the first connecting pipe 40 and located between the first pipeline 20 and the inlet 10 a to open or close the passage between the first pipeline 20 and the inlet 10 a .

[0059] By setting the first valve body 61, the opening and closing of the first pipeline 20 can be controlled. Figure 3 When the first valve body 61 closes the first connecting pipe 40 between the first pipeline 20 and the inlet 10a, the liquid can only enter the second pipeline 30 through the first connecting pipe 40 for heating, and then enter the second connecting pipe 50 after heating and then be discharged through the outlet 10b. After heating for a period of time, the first valve body 61 can be opened, so that the first pipeline 20 and the second pipeline 30 are connected at the same time, so that the beneficial effect of increasing the gas output after rapid gas output can be achieved. The first valve body 61 can be opened or closed by the main controller of the steam appliance through intelligent control, or it can be opened or closed by manual mechanical control.

[0060] And / or, the valve body assembly further includes a second valve body 62, which is disposed in the first connecting pipe 40 and located between the second pipeline 30 and the inlet 10a, for opening or closing the passage between the second pipeline 30 and the inlet 10a.

[0061] The effect of setting the second valve body 62 alone is similar to the above setting, which will not be described in detail here. Figure 4, the opening of the first valve body 61 and the second valve body 62 can be controlled to achieve a smooth transition of gas. During normal operation, the heat pipe quickly heats the steam pipeline, the second valve body 62 corresponding to the second pipeline 30 of the steam generator 100 is fully opened, the pipeline cross-sectional area of ​​the first connecting pipe 40 opened by the second valve body 62 is A, the first valve body 61 corresponding to the first pipeline 20 is closed, and the water is quickly heated in the second pipeline 30 to generate steam. After the steam outlet generates stable steam, the sensor 70 located at the outlet 10b transmits a signal to the control system (the control system can be a controller of the steam generator or an overall main control chip of the steam appliance) to control the first valve body 61 to open a part of it. The pipe cross-sectional area of ​​the first connecting pipe 40 opened by the first valve body 61 is B, and the second valve body 62 closes a part of the first connecting pipe 40. During the closing process of the second valve body 62, the corresponding cross-sectional area of ​​the first connecting pipe 40 is C. In order to ensure the stability of steam output during the switching process from the second pipeline 30 to the first pipeline 20, B plus C is approximately equal to A during the switching process, ensuring that the cross-sectional area of ​​the steam pipeline does not change much. After the pipeline switching is completed, the steam continues to be heated in the first pipeline 20, thereby enabling the steam generator 100 to have the technology of quickly generating steam and strong scale resistance.

[0062] Combined with reference Figures 1 to 3 In one embodiment of the present application, the steam generator 100 further includes a sensor 70 , which is disposed at an outlet 10 b of the steam generator 100 . The sensor 70 is at least one of a pressure sensor 70 , a temperature sensor 70 , and a timing sensor 70 .

[0063] By setting the sensor 70 at the outlet 10b, various parameters at the outlet 10b can be intelligently detected, thereby realizing intelligent control of the steam generator 100. For example, when a pressure sensor is set, the opening or closing of the first valve body 61 and the second valve body 62 mentioned in the above embodiment can be realized by detecting the pressure at the outlet 10b, and the overall heating power of the heating body 10 can also be controlled. The temperature sensor can detect the temperature at the outlet 10b, thereby realizing the adjustment of the heating power of the heating body 10, and further can be combined with the adjustment of the flow rate of the water flow entering at the inlet 10a, thereby realizing the discharge of the preset temperature. Of course, a timing sensor can also be set to calculate the exhaust time at the outlet 10b, thereby further realizing the statistics of the exhaust time of the steam in the overall pipeline. Of course, it can be understood that the above-mentioned sensor 70 can be used alone or in combination.

[0064] In one embodiment of the present application, the range value of the pipe cross-sectional area S1 of the first pipe 20 is: 7 mm 2 <S1≤28.5mm 2 ;

[0065] It is understandable that the cross-section of the first pipeline 20 can be circular, square or other shapes. That is to say, the first pipeline 20 can be a circular pipeline, a square pipeline or a pipeline with other shapes. When setting the cross-sectional area of the first pipeline, since the cross-sectional area of the first pipeline 20 should be larger than that of the second pipeline 30, therefore, the first pipeline 20 can be considered as the upper limit of the flow rate that the overall flow channel can pass through. Therefore, on the basis of being larger than the second pipeline 30, the first pipeline 20 also needs to consider the upper limit of the liquid flow rate and the heating efficiency. Therefore, it is set in the range of 7mm 2 <S1≤28.5mm 2 , for example, set to 7mm 2 、9mm 2 、10mm 2 、15mm 2 、20mm 2 、28.5mm 2 . At this time, it can not only ensure the passing efficiency of the liquid in the entire liquid path, but also effectively improve the overall heating efficiency.

[0066] And / or, the range value of the cross-sectional area S2 of the second pipeline 30 is: 0.75mm 2 ≤S2≤7mm 2 .

[0067] It is understandable that the cross-section of the second pipeline 30 can be circular, square or other shapes. That is to say, the second pipeline 30 can be a circular pipeline, a square pipeline or a pipeline with other shapes. The shape of the second pipeline 30 can be the same as that of the first pipeline 20. For example, both are circular to facilitate processing and the passing of liquid. Of course, they can also be of different shapes, which are also within the protection scope of this application.

[0068] When setting the cross-sectional area of the second pipeline 30, it is necessary to consider the passing efficiency and heating efficiency of the liquid in the second pipeline. Therefore, it is set in the range of 0.75mm 2 ≤S1≤7mm 2 , for example, set to 0.75mm 2 、1mm 2 、2mm 2 、3mm 2 、5mm 2 、7mm 2 . At this time, it can not only ensure the passing efficiency of the liquid in the second pipeline 30, but also effectively improve its heating efficiency.

[0069] In an embodiment of the present application, the heating main body 10 includes a main body portion 11 and a heating element 13. The first pipeline 20 and the second pipeline 30 are arranged in the main body portion 11, and the heating element 13 is arranged in the main body portion 11.

[0070] The heating element 13 can be a resistance heating tube or an electromagnetic heating element 13. The main body 10 is heated by the resistance heating tube or the electromagnetic heating element, so that the liquid in the first pipeline 20 and the second pipeline 30 arranged in the main body part 11 can be heated. The main body part 11 can be made of a heat-conducting material, such as a heat-conducting metal part such as aluminum or ferroalloy, etc. Of course, it can also be that a heat-conducting medium is arranged inside a heat-insulating shell, and the heat-conducting medium is heated by the heating element 13 for heating. The shape of the main body part 11 can be set according to requirements and will not be elaborated here.

[0071] Furthermore, the first pipeline 20, the second pipeline 30 and the heating element 13 are all located inside the main body part 11. By arranging the first pipeline 20, the second pipeline 30 and the heating element 13 inside the main body part 11, the effect of rapid heating can be achieved.

[0072] The present invention also provides a steam electrical appliance, which includes a steam generator 100. The specific structure of the steam generator 100 refers to the above-mentioned embodiments. Since this steam electrical appliance adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. The steam electrical appliance is an electric steamer, a clothes iron, an electric iron or a steam fryer.

[0073] Combined with reference to Figures 1 to 4 , the present invention also provides a method for controlling the air outlet of a steam electrical appliance, including:

[0074] Step A: The valve assembly opens the first connecting pipe 40 and the first pipeline 20, and the air flow flows out in sequence through the inlet 10a, the first connecting pipe 40, the second pipeline 30, the second connecting pipe 50 and the outlet 10b;

[0075] Step B: After detecting that the air flow parameter at the outlet 10b is a preset parameter, the valve assembly gradually opens the first connecting pipe 40 and the second pipeline 30, and gradually closes part of the first connecting pipe 40 and the first pipeline 20, and the air flow flows out in sequence through the inlet 10a, the first connecting pipe 40, the first pipeline 20, the second connecting pipe 30 and the outlet 10b.

[0076] By setting the valve assembly, the opening and closing of the first pipeline can be controlled. Specifically, refer to Figure 3, when the first valve body 61 opens the first connecting pipe 40 between the first pipeline 20 and the inlet 10a, the liquid enters the second pipeline 30 through the first connecting pipe 40 for heating, and after heating, it enters the second connecting pipe 50 and is discharged through the outlet 10b. After heating for a period of time, the valve assembly gradually opens the first connecting pipe 40 and the second pipeline 50, and gradually closes part of the first connecting pipe 40 and the first pipeline 20. In this way, the first pipeline 20 and the second pipeline 30 are simultaneously conducted, so that the beneficial effect of increasing the gas outlet volume after a rapid gas outlet can be achieved. At the same time, since the valve assembly gradually opens the first connecting pipe 40 and the second pipeline 50, and gradually closes part of the first connecting pipe 40 and the first pipeline 20, the steady switching of the gas path can be realized. The valve assembly can be intelligently controlled to open or close by the main controller of the steam electrical appliance, or can be manually mechanically controlled to open or close.

[0077] The preset parameters at the outlet can be air pressure parameters, temperature parameters, or gas outlet time parameters. A pressure sensor can be used to detect the pressure at the outlet 10b to realize the opening or closing of the first valve body 61 and the second valve body 62 mentioned in the above embodiments, and can also control the overall heating power of the heating body 10. A temperature sensor can be used to detect the temperature at the outlet 10b, so as to realize the adjustment of the heating power of the heating body 10, and further, the flow rate of the water flowing into the inlet 10a can be adjusted to realize the discharge at a preset temperature. Of course, a timing sensor can also be set to calculate the gas exhaust time at the outlet 10b, and further realize the statistics of the steam exhaust time of the overall pipeline. Of course, it can be understood that the above sensors 70 can be used alone or in combination.

[0078] In the step of "the valve assembly gradually opens the first connecting pipe and the second pipeline, and gradually closes part of the first connecting pipe and the first pipeline", it includes:

[0079] The valve assembly includes a first valve body 61. The first valve body 61 is arranged on the first connecting pipe 40 and is located between the first pipeline 20 and the inlet 10a. The valve assembly includes a second valve body 62. The second valve body 62 is arranged on the first connecting pipe 40 and is located between the second pipeline 30 and the inlet 10a;

[0080] The cross-sectional area of the pipeline opened by the second valve body for the first connecting pipe is A, the cross-sectional area of the pipeline opened by the first valve body for the first connecting pipe and the second pipeline is B, and the cross-sectional area of the pipeline after the second valve gradually closes part of the first connecting pipe and the first pipeline is C, satisfying B + C = A.

[0081] The opening of the first valve body 61 and the second valve body 62 can be controlled to achieve a smooth transition of gas. During normal operation, the heat pipe quickly heats the steam pipeline, the second valve body 62 corresponding to the second pipeline 30 of the steam generator 100 is fully opened, the pipeline cross-sectional area of ​​the first connecting pipe 40 opened by the second valve body 62 is A, the first valve body 61 corresponding to the first pipeline 20 is closed, and the water is quickly heated in the second pipeline 30 to generate steam. After the steam outlet generates stable steam, the sensor 70 located at the outlet 10b transmits a signal to the control system (the control system can be a controller of the steam generator or an overall main control chip of the steam appliance), which controls the first valve body 61 to open a part of the first connecting pipe 40. The pipe cross-sectional area of ​​the first connecting pipe 40 opened by the first valve body 61 is B, and the second valve body 62 closes a part of the first connecting pipe 40. During the closing process of the second valve body 62, the corresponding cross-sectional area of ​​the first connecting pipe 40 is C. In order to ensure the stability of steam output during the switching process from the second pipeline 30 to the first pipeline 20, B plus C is approximately equal to A during the switching process, ensuring that the cross-sectional area of ​​the steam pipeline does not change much. After the pipeline switching is completed, the steam continues to be heated in the first pipeline 20, thereby enabling the steam generator 100 to have the technology of quickly generating steam and strong scale resistance.

[0082] The present invention also provides a readable storage medium, the readable storage medium comprising a memory, a processor, and a control program of a steam appliance stored in the memory and executable on the processor, the processor implementing the method as described above when executing the steam appliance, which is not described in detail here. The specific implementation of the storage medium of this application is basically the same as the above-mentioned control method embodiments, which are not described in detail here.

[0083] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
