In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples.

Hereinafter, the water-vapor separation device 2 according to the embodiment of the present application is described with reference to the accompanying drawings. Wherein the water-steam separation device 2 is adapted to be arranged in the housing 1 of the steam generator 100, and water-steam separation can be achieved.

As shown in fig. 2-4, the water-steam separation device 2 further includes a flow guiding structure 22, the flow guiding structure 22 is disposed on the separation plate 21, the flow guiding structure 22 is adapted to be disposed opposite to the steam outlet 1b, and the flow guiding structure 22 is adapted to be protruded from the separation plate 21 along a direction close to the steam outlet 1b, so that for the separation plate 21 and the flow guiding structure 22, a distance between the flow guiding structure 22 and the steam outlet 1b may be smaller than a distance between the separation plate 21 and the steam outlet 1 b.
Since the steam generator 100 can boil water by heating the water, a large amount of steam is generated, and the water is easily sprayed from the steam outlet 1b due to the boiling of water, etc.; when the water-vapor separation device 2 in the application is applied to the steam generator 100, certain water-vapor separation can be realized through the action of the separation plate 21, and the dryness of steam discharged by the steam generator 100 is reduced, however, if a certain amount of water is still mixed after the steam passes through the separation plate 21, the water flows to one side of the separation plate 21 facing the steam outlet 1b, and the water is easy to overflow through the steam outlet 1b, and because the flow guide structure 22 is arranged opposite to the steam outlet 1b and the flow guide structure 22 protrudes out of the separation plate 21 towards the direction close to the steam outlet 1b, the flow guide structure 22 can play a role of shielding the steam outlet 1b to a certain extent, so that the dryness of the steam discharged by the steam generator 100 is prevented from being sprayed out of the steam outlet 1b, and the dryness of the steam generator 100 is further reduced.
When the steam generator 100 using the water-steam separation device 2 is applied to a steam cooking appliance, good food taste can be ensured, excessive water accumulation in a cooking cavity is avoided, maintenance and cleaning of the steam cooking appliance are facilitated, and meanwhile, the utilization rate of the steam cooking appliance to water is improved, so that the effect of saving water is achieved.
Wherein, the outer peripheral wall of the diversion structure 22 is formed into a diversion surface 22a, the diversion surface 22a is used for guiding the water on the diversion surface 22a to the separation plate 21, so that the water on the diversion structure 22 is prevented from being gathered on the diversion structure 22 and is easy to be sprayed out from the steam outlet 1b, thereby ensuring the dryness of the steam sprayed out by the steam generator 100.
According to the water-steam separation device 2 of the embodiment of the invention, the flow guiding structure 22 is arranged on the separation plate 21, so that the flow guiding structure 22 protrudes from the separation plate 21 towards the steam outlet 1b, and the flow guiding structure 22 is suitable for being arranged opposite to the steam outlet 1b, thereby effectively reducing the dryness of steam sprayed by the steam generator 100 when the water-steam separation device 2 is applied to the steam generator 100; when the steam generator 100 is applied to the steam cooking appliance, the taste of food can be improved, the cleaning of the steam cooking appliance is facilitated, and the utilization rate of water resources is improved.
In some embodiments of the invention, as shown in fig. 2 and 3, the cross-sectional area of the flow guiding structure 22 gradually decreases, or gradually increases, or remains unchanged, in a direction perpendicular to the separating plate 21, in a direction away from the separating plate 21, and then the cross-sectional area of the flow guiding structure 22 may gradually decrease, or gradually increase, or remain unchanged, in a direction from the separating plate 21 towards the steam outlet 1b, in other words, the area of the outer contour corresponding to the flow guiding surface 22a may gradually decrease, or gradually increase, or remain unchanged, in a direction from the separating plate 21 towards the steam outlet 1 b. Therefore, the structure of the flow guiding structure 22 can be designed in a diversified manner, and the specific structure of the flow guiding structure 22 can be flexibly adjusted according to the differentiated requirements of practical applications.
For example, in the direction from the separator 21 toward the steam outlet 1b, the flow guiding structure 22 may be formed in a columnar structure, such as a cylindrical structure or a prismatic structure, when the cross-sectional area of the flow guiding structure 22 is kept constant all the time, and the flow guiding structure 22 may be formed in a spherical structure or a tapered structure, such as a conical structure or a pyramid structure, when the cross-sectional area of the flow guiding structure 22 is gradually reduced or gradually increased toward the direction approaching the steam outlet 1 b. Of course, the arrangement of the flow guiding structure 22 is not limited thereto.
For example, in the example of fig. 2 to 4, when the water-vapor separation device 2 is applied to the steam generator 100, the separation plate 21 may include a first plate portion 211, the first plate portion 211 may be disposed below the steam outlet 1b, the flow guiding structure 22 may be disposed at an upper side of the first plate portion 211, and the flow guiding structure 22 is disposed to protrude upward from the first plate portion 211, the cross-sectional area of the flow guiding structure 22 is gradually reduced from bottom to top in a direction perpendicular to the first plate portion 211, and the flow guiding surface 22a is configured to include a spherical surface and a cylindrical surface, the spherical surface and the cylindrical surface being disposed along an axial direction of the flow guiding structure 22, and the cylindrical surface being connected at a lower side of the spherical surface. The height of the sphere and the height of the cylindrical surface can be specifically set according to practical applications.
It should be noted that, in the present application, the specific processing manner of the flow guiding structure 22 is not particularly limited; for example, the flow guiding structure 22 may be formed as an integral piece with the separating plate 21, for example, the flow guiding structure 22 may be formed by protruding a part of the separating plate 21, where the flow guiding structure 22 may be formed as a hollow structure, for example, the flow guiding structure 22 may be separately formed with the separating plate 21, and then the flow guiding structure 22 is fixed on the separating plate 21, where the flow guiding structure 22 may be formed as a hollow structure or a solid structure.
In some embodiments of the present invention, as shown in fig. 2 and 3, the guide surface 22a is formed as a revolution surface, facilitating the processing of the guide surface 22 a. The term "rotation surface" is understood to mean a curved surface formed by rotating a curve around a fixed straight line, and the term "curve" is understood in a broad sense to include a planar curve and a spatial curve.
Of course, the guide surface 22a may be formed as a non-rotating surface; for example, the guide surface 22a may include a first guide surface and a second guide surface disposed along the circumferential direction of the guide structure 22, where the first guide surface is formed as a part of a cylindrical surface, and the second guide surface is formed as a part of a conical surface, so as to further enrich the structural design of the guide structure 22.
In some embodiments of the present invention, the guide surface 22a includes at least one of a cylindrical surface, a conical surface, and a spherical surface, and the guide surface 22a may be configured to: 1. a cylindrical surface; 2. the guide surface 22a may be formed as a cylindrical surface or a conical surface; 3. a spherical surface; 4. including cylindrical and conical surfaces, which may then be disposed axially along the guide surface 22 a; 5. including cylindrical and spherical surfaces, which may be disposed in the axial direction of the guide surface 22 a; 6. including a conical surface and a spherical surface, which may be disposed along the axial direction of the guide surface 22 a; 7. including cylindrical, conical and spherical surfaces. Therefore, the structural design of the flow guiding surface 22a is enriched, the diversified design of the flow guiding structure 22 is realized, and the actual differentiation requirement is met better.
For example, in the example of fig. 2-4, the guide surface 22a includes a spherical surface and a cylindrical surface, the cylindrical surface being connected to the underside of the spherical surface.
In some embodiments of the present invention, as shown in fig. 3, in the direction perpendicular to the separating plate 21, the area of the orthographic projection of the flow guiding structure 22 is larger than the area of the orthographic projection of the steam outlet 1b, and then in the direction perpendicular to the separating plate 21, the outer contour of the orthographic projection of the flow guiding structure 22 may be located outside the outer contour of the orthographic projection of the air outlet 1b, so that in the direction from the separating plate 21 toward the steam outlet 1b, so as to effectively ensure the "shielding effect" of the flow guiding structure 22 on the steam outlet 1b, and reduce the dryness of the steam sprayed by the steam generator 100.
In some embodiments of the present invention, as shown in fig. 6, a through first backflow port 21a is formed on the separation plate 21, so that the first backflow port 21a penetrates through the separation plate 21 along the thickness direction of the separation plate 21, and water on one side of the thickness of the separation plate 21 can flow to the other side of the thickness of the separation plate 21 through the first backflow port 21a, so that when the water-vapor separation device 2 is applied to the steam generator 100, water on one side of the separation plate 21 facing the steam outlet 1b can flow to one side of the separation plate 21 facing away from the steam outlet 1b through the first backflow port 21a, and then is convenient to flow back to a cavity for containing water in the casing 1, thereby avoiding water from collecting on the separation plate 21, effectively avoiding water on the separation plate 21 from easily overflowing from the steam outlet 1b due to boiling and the like, and guaranteeing dryness of steam sprayed by the steam generator 100.
Of course, it is understood that the first return port 21a may not be formed in the separation plate 21, as shown in fig. 3.
In some embodiments of the present invention, as shown in fig. 2 to 4, the separation plate 21 is adapted to divide the chamber 10 within the housing 1 into a first chamber 10a and a second chamber 10b, the first chamber 10a being used to hold water, the second chamber 10b being located at least partially on the upper side of the first chamber 10a, the second chamber 10b may be located at the upper side of a portion of the first chamber 10a (as shown in fig. 2 and 4), or the second chamber 10b may be located at the upper side of the entire first chamber 10 a. Wherein the steam outlet 1b is formed at the top of the second chamber 10 b.
As shown in fig. 2 and 4, the separating plate 21 includes a first plate portion 211, where the first plate portion 211 is adapted to be horizontally disposed, and the flow guiding structure 22 is disposed on the first plate portion 211, so that the first plate portion 211 is adapted to be located between the second chamber 10b and at least a portion of the first chamber 10a, and thus the first plate portion 211 is located at the bottom of the second chamber 10b, so that the steam outlet 1b can be disposed vertically opposite to the first plate portion 211, and it is convenient to implement that the flow guiding structure 22 and the steam outlet 1b are disposed vertically opposite to each other.
As shown in fig. 3, the separation plate 21 further includes a second plate portion 212, the second plate portion 212 is connected to the first plate portion 211, a steam outlet 21b is formed on the second plate portion 212, the steam outlet 21b is communicated with the first chamber 10a and the second chamber 10b, and then the water in the first chamber 10a is heated and converted into steam, and then the steam can flow into the second chamber 10b through the steam outlet 21b, and finally is discharged through the steam outlet 1 b. Obviously, the arrangement of the second plate portion 212 does not affect the normal discharge of steam, and meanwhile, when the high-temperature steam encounters the second plate portion 212, the moisture carried by the high-temperature steam can be condensed on the second plate portion 212, so that excessive water can be prevented from being carried into the second chamber 10b, and then the water in the second chamber 10b is reduced, so that the water amount overflowed from the steam outlet 1b is further reduced, and the dryness of the steam sprayed by the steam generator 100 is further reduced.
It is understood that the number and arrangement of the steam outlets 21b may be specifically set according to actual requirements.
Alternatively, the second plate portion 212 and the first plate portion 211 may be formed as a single piece, so as to save an assembling process between the first plate portion 211 and the second plate portion 212, and at the same time, a connection structure for connecting the first plate portion 211 and the second plate portion 212 may not be required to be processed, which is beneficial to simplifying the structure of the separation plate 21; for example, in the example of fig. 3 and 6, the second chamber 10b is located at an upper side of a portion of the first chamber 10a, the second chamber 10b may be disposed flush with another portion of the first chamber 10a in an up-down direction, and at this time, the second plate portion 212 and the first plate portion 211 may be bent to be connected, and then the first plate portion 211 and the second plate portion 212 may be formed by bending the separation plate 21, respectively. Of course, the second plate 212 and the first plate 211 may be formed separately, and the second plate 212 and the first plate 211 may be fixedly connected.
In some embodiments of the present invention, as shown in fig. 2 to 4, the second plate portion 212 is vertically (e.g., vertically in fig. 3), and the steam discharge port 21b is formed at an upper end of the second plate portion 212 such that the steam discharge port 21b is spaced far from the bottom wall of the first chamber 10a, which is advantageous in preventing water of the first chamber 10a from splashing to the second chamber 10b through the steam discharge port 21b under boiling, and further reducing the amount of water carried into the second chamber 10 b.
It will be appreciated that the second plate portion 212 may also be arranged obliquely with respect to the vertical direction, which may increase the contact area of the second plate portion 212 with the high temperature steam to some extent, so that more water carried in the high temperature steam condenses on the second plate portion 212. The second plate 212 may extend obliquely from the bottom up toward the first chamber 10a, or may extend obliquely from the bottom up toward the second chamber 10 b.
Alternatively, in the example of fig. 3, the second plate portion 212 may extend upward from the edge of the first plate portion 211, and the separation plate 21 may be formed as a single piece, which is convenient for processing. At this time, the second plate portion 212 may extend vertically upward from the edge of the first plate portion 211, or the second plate portion 212 may extend obliquely upward from the edge of the first plate portion 211. Of course, the second plate portion 212 may be disposed at a distance from the edge of the first plate portion 211.
