Description

Technical Field

[0001] The utility model belongs to the technical field of steam generator manufacturing, in particular to a water spray-proof steam generator. Background Art

[0002] A steam generator is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. Specifically, a water pump is connected to the steam generator's water inlet. A programmed amount of liquid water (amount sufficient to quickly boil) is pumped from a water tank each time and fed into the steam generator through the inlet. High-power heating tubes located at the bottom of the steam generator heat the liquid water, which boils in the steam generator to produce steam. The steam is then discharged through the steam outlet, where it comes into contact with a heat exchange device for heat exchange. However, during use, it has been found that when the liquid water inside the steam generator boils, small particles of liquid water splash out of the steam outlet, creating a water spray phenomenon. Consequently, when a large number of small liquid water particles accumulate on the surface of the heat exchange device, they form a water film, which changes the heat exchange coefficient, prolongs the heating time, and reduces production capacity. Furthermore, when the moisture in the steam contacts the surface of the heat exchange device over time, a scale layer may form. This can cause differential thermal expansion of the heat exchange device and cracks on the surface, thus affecting production efficiency and product quality. Utility Model Content

[0003] (1) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present utility model is to provide a water-spraying-proof steam generator to solve the technical problems that the existing steam generator is prone to water spraying during the heating process, which reduces the heat exchange coefficient of the heat exchange device, affects the production capacity, and easily causes cracks on the surface of the heat exchange device, thereby affecting the production efficiency and product quality.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A water-spray-proof steam generator comprises: a bottom cover with an upper opening, a sealing member arranged above the bottom cover, the sealing member comprising a sealing portion in an annular structure arranged around the edge of the bottom cover opening, and a partitioning portion arranged in the middle of the sealing portion and having one end and the other end of the sealing portion extending into the bottom interior, the partitioning portion being annular in structure, an upper cover arranged above the sealing member, a water inlet and a steam outlet being provided on the upper cover, wherein the edge of the bottom surface of the upper cover abuts against the sealing portion and the middle portion extends downward to form a shape adapted to the partitioning portion and mutually interlocked with the partitioning portion The abutting partition wall cooperates with the partition portion to divide the internal space enclosed by the bottom cover and the upper cover into a mutually independent liquid water cavity interconnected with the water inlet and a gaseous water cavity interconnected with the steam outlet. The partition wall is provided with a steam channel connecting the liquid water cavity and the gaseous water cavity. The device also includes: a heating device disposed on the bottom surface of the bottom cover and corresponding to the liquid water cavity, capable of heating liquid water entering the liquid water cavity from the water inlet to form steam, which is discharged into the gaseous water cavity and finally discharged from the steam outlet;

[0008] The present application improves the sealing member and the upper cover, and configures the sealing member into a sealing portion and a partitioning portion. A partitioning wall is provided at the bottom of the upper cover, and a steam channel is opened on the partitioning wall. The sealing portion is located between the bottom cover and the upper cover to seal the gap between the bottom cover and the upper cover to prevent steam and liquid water from overflowing from the gap. The partitioning portion cooperates with the partitioning wall of the upper cover to divide the interior of the steam generator into two independent gaseous water chambers and liquid water chambers. The liquid water chamber and the gaseous water chamber correspond to the water inlet and the steam outlet, respectively. In this way, when liquid water enters the liquid water chamber from the water inlet, it will be heated in the liquid water chamber to form steam. The steam can enter the gaseous water chamber through the steam channel and finally be discharged from the steam outlet. Since there is only steam in the gaseous water chamber, small particles of liquid water will not splash out from the steam outlet, thereby ensuring the heat exchange coefficient, production efficiency and product quality of the heat exchange device.

[0009] In some embodiments, the steam outlet is located on the upper cover at a position farthest from the steam channel;

[0010] A small amount of liquid water will enter the gaseous water cavity through the steam channel during the boiling process. The steam outlet is set at the position farthest from the steam channel. Even if a small amount of liquid water enters the gaseous water cavity, it is difficult to splash out from the steam outlet over a long distance.

[0011] In some embodiments, the liquid water chamber and the heating device are both annular in structure, wherein the water inlet is located on the upper cover at a position farthest from the steam channel;

[0012] The water inlet is set at the position farthest from the steam channel. When liquid water enters from the water inlet, it flows along the liquid water cavity of the annular structure. Since the heating device is annular in structure, the liquid water is heated by the heating device during the flow of liquid water. When it reaches the position of the steam channel, the liquid water has boiled to form steam. This can prevent the liquid water from boiling near the steam channel, causing a small amount of liquid water to enter the gaseous water cavity.

[0013] In some embodiments, the partition portion is provided with an embedding groove for the lower end of the partition wall to be embedded;

[0014] The embedding groove in which the lower end of the partition is embedded can ensure the sealing of the combination between the partition and the partition wall.

[0015] In some embodiments, the bottom cover, the seal, and the upper cover are respectively provided with locking holes for the locking member to pass through to lock the bottom cover, the seal, and the upper cover together;

[0016] Connecting the bottom cover, the seal and the upper cover together can ensure the overall firmness of the steam generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0028] The utility model provides a water spray-proof steam generator, comprising: a bottom cover 1 with an upper opening, a sealing member 2 arranged above the bottom cover 1, the sealing member 2 comprising a sealing portion 201 in an annular structure arranged around the edge of the opening of the bottom cover 1 and a partition 202 arranged in the middle of the sealing portion 201 and one end and the other end of the sealing portion 201 extending into the interior of the bottom cover 1, the partition 202 in an annular structure, arranged on a top cover 3 above the sealing member 2, a water inlet 301 and a steam outlet 302 are provided on the top cover 3, wherein the bottom edge of the top cover 3 abuts against the sealing portion 201 and the middle portion extends downward to form a shape adapted to the partition 202 and is in contact with the partition 202 abut against the partition wall 303, the partition wall 303 and the partition part 202 cooperate with each other to divide the internal space enclosed by the bottom cover 1 and the upper cover 3 into independent liquid water chambers 5 interconnected with the water inlet 301 and gaseous water chambers 6 interconnected with the steam outlet 302, and a steam channel 3031 connecting the liquid water chamber 5 and the gaseous water chamber 6 is opened on the partition wall 303, and also includes: a heating device 4 arranged on the bottom surface of the bottom cover 1 and corresponding to the liquid water chamber 5, which can heat the liquid water entering the liquid water chamber 5 from the water inlet 301 to form steam, discharge it into the gaseous water chamber 6 and finally discharge it from the steam outlet 302.

[0029] Specifically, the water pump is connected to the water inlet 301, and the heating device 4 is arranged at the bottom of the liquid water cavity 5. When the liquid water enters the liquid water cavity 5 from the water inlet 301, it will be heated in the liquid water cavity 5 to form steam. Then the steam enters the gaseous water cavity 6 through the steam channel 3031 and is finally discharged from the steam outlet 302. Figure 6 As shown, Figure 6 The solid line represents liquid water, and the dotted line represents steam. Since only steam exists in the gaseous water cavity 6 , small particles of liquid water will not splash out from the steam outlet 302 .

[0030] Preferably, the present application also optimizes the position of the steam outlet 302, and sets the steam outlet 302 at the position farthest from the steam channel 3031. In this way, even if a small amount of liquid water boils near the steam channel 3031 or enters the gaseous water cavity 6, it is difficult to reach the steam outlet 302 and splash out.

[0031] Preferably, the present application arranges the liquid water chamber 5 and the heating device 4 into an annular structure, and arranges the water inlet 301 at the position farthest from the steam channel 3031, that is, at one end of the annular structure. In this way, when liquid water enters from the water inlet 301, it flows along the liquid water chamber 5 of the annular structure. During the flow, the liquid water is heated by the heating device 4 of the annular structure. When it reaches the position of the steam channel 3031, the liquid water has boiled to form steam. This can avoid the boiling of liquid water near the steam channel 3031, causing a small amount of liquid water to enter the gaseous water chamber 6.

[0032] Preferably, the present application provides an embedding groove 2021 on the partition 202. When the upper cover 3 is closed over the seal 2, the lower end of the partition wall 303 arranged thereon will be embedded in the embedding groove 2021, so that the partition 202 and the partition wall 303 are more tightly combined.

[0033] Specifically, the position on the partition 202 corresponding to the steam channel 3031 is the horizontal plane 2022 .

[0034] Specifically, the present application provides locking holes on the bottom cover 1, the sealing portion 201 of the sealing member 2 and the upper cover 3 respectively, and the bottom cover 1, the sealing member 2 and the upper cover 3 can be locked together through threads.

[0035] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
