During steam cleaning, steam is introduced into the area being cleaned, such as the impeller of a range hood. Currently, water pumps are equipped with pressure relief valves to release pressure when the internal pressure is high, meeting safety regulations. However, including pressure relief valves on water pumps hinders their miniaturization. Summary of the Invention

[0037] Please refer to Figures 1 to 6 A steam generating system 100 according to an embodiment of this application includes a water pump 12 and a steam generator 14. The water pump 12 includes a volumetric cavity 16, an inlet pipe 18, and an outlet pipe 20. The volumetric cavity 16 has a volumetric chamber 22 inside. The inlet pipe 18 is connected to the volumetric cavity 16. The outlet pipe 20 is connected to the volumetric cavity 16. The steam generator 14 is connected to the outlet pipe 20 via a first external water pipe 17. The inlet pipe 18 is also fitted with a second external water pipe 24. The steam generating system 100 also includes a clamp 200, which clamps at least one of the portion fitted with the first external water pipe 17 of the outlet pipe 20 and the portion fitted with the second external water pipe 24 of the inlet pipe 18. The clamp 200 is configured to cause the first external water pipe 17 to detach from the outlet pipe 20 and / or the second external water pipe 24 to detach from the inlet pipe 18 when the pressure in the volume chamber 22 is greater than a set pressure.

[0038] The aforementioned water pump 12 uses a clamp 200 to tighten the external water pipe, thereby sealing the external water pipe with the outlet pipe 20 and the inlet pipe 18. Furthermore, the clamp 200 is configured to allow the external water pipe 17 to detach from the outlet pipe 20 and / or the inlet pipe 18 when the pressure inside the volume chamber 22 exceeds the set pressure. This allows for pressure relief in case of abnormal internal pressure in the water pump 12 to meet safety requirements, replacing the original pressure relief valve solution and facilitating the miniaturization of the water pump 12.

[0039] Specifically, the steam generating system 100 is equipped with a water pump 12, which has a volumetric cavity 16. Inside the volumetric cavity 16 is a volumetric chamber 22. An inlet pipe 18 connects to the volumetric chamber 22 and can also connect to a water tank (not shown). An outlet pipe 20 connects to the volumetric chamber 22. The steam generator 14 can be connected to the outlet pipe 20 via a first external water pipe 17. A second external water pipe 24 is fitted around the outer periphery of the inlet pipe 18. A clamp 200 can tighten at least one of the portions of the outlet pipe 20 fitted with the first external water pipe 17 and the inlet pipe 18 fitted with the second external water pipe 24. Figure 6In the embodiments shown, the thickness of the clamp 200 can be represented by H, where H is 0.8mm ± 0.1mm. When the pressure inside the volume chamber 22 is greater than the set pressure, in one embodiment, the first external water pipe 17 detaches from the outlet pipe 20; in another embodiment, the second external water pipe 24 detaches from the inlet pipe 18; and in yet another embodiment, the first external water pipe 17 detaches from the outlet pipe 20 and the second external water pipe 24 detaches from the inlet pipe 18. This allows for pressure relief in case of abnormal internal pressure in the water pump 12 to meet safety requirements, replacing the original pressure relief valve solution and facilitating the miniaturization of the water pump 12.

[0040] It should be noted that the clamping force of the clamp 200 on the external water pipe portion where the water pipe is fitted can be determined through testing and simulation. For example, taking the second external water pipe 24 as an example. During the test, the clamp 200 first clamps the portion 19 (hereinafter referred to as pipe portion 19) of the second external water pipe 24 fitted onto the inlet pipe 18 with a certain clamping force, so that the second external water pipe 24 is connected to the inlet pipe 18. Then, the pressure in the volume chamber 22 is increased to the set pressure. During the pressure increase process, if the clamp 200 is released before the pressure in the volume chamber 22 reaches the set pressure, and the second external water pipe 24 falls off the inlet pipe 18, it indicates that the clamping force is too small. If the pressure in the volume chamber 22 exceeds the set pressure, and the clamp 200 is not released, and the second external water pipe 24 is still connected to the inlet pipe 18, it indicates that the clamping force is too large. The clamping force can be adjusted by adjusting the diameter of the circle formed by the clamp 200.

[0041] In the illustrated embodiment, clamp 200 tightens the pipe portion 19 of the second external water pipe 24 that is fitted onto the inlet pipe 18. The clamp 200 is configured to cause the second external water pipe 24 to detach from the inlet pipe 18 when the pressure in the volume chamber 22 is greater than a set pressure.

[0042] In one embodiment, the clamp 200 clamps the portion of the first external water pipe 17 that is fitted onto the water outlet pipe 20, wherein the clamp 200 is configured to cause the first external water pipe 17 to detach from the water outlet pipe 20 when the pressure in the volume chamber 22 is greater than a set pressure.

[0043] In one embodiment, clamp 200 clamps the portion of the first external water pipe 17 fitted onto the outlet pipe 20 and the portion of the second external water pipe 24 fitted onto the inlet pipe 18. The clamp 200 is configured to cause the first external water pipe 17 to detach from the outlet pipe 20 and the second external water pipe 24 to detach from the inlet pipe 18 when the pressure in the volume chamber 22 is greater than a set pressure.

[0044] In some cases, the thickness of clamp 200 can be 0.7mm, 0.8mm, 0.9mm, or other values ​​between 0.7mm and 0.9mm.

[0045] In some implementations, please refer to Figure 1 , Figure 2 and Figure 6 The clamp 200 includes a clamping part 26 and an adjusting part 28. The clamping part 26 is connected to the adjusting part 28 and is in the shape of an arc. The clamping part 26 clamps at least one of the portion where the first external water pipe 17 of the outlet pipe 20 is fitted and the portion where the second external water pipe 24 of the inlet pipe 18 is fitted. The adjusting part 28 is connected to both ends of the clamping part 26 and is used to adjust the diameter of the clamping part 26 when operated. In this way, the clamp 200 can be adapted to different models of external water pipes 24, which facilitates installation and adjustment of clamping force.

[0046] Specifically, the clamp 200 is provided with a clamping part 26 and an adjusting part 28. The clamping part 26 can be constructed as an arc-shaped ring structure. In the illustrated embodiment, the clamping part 26 can clamp the second external water pipe 24 onto the pipe portion 19 of the water inlet pipe 18. The adjusting part 28 can be fixedly connected to both ends of the clamping part 26. The inner diameter of the clamping part 26 can be D. In one embodiment, under normal conditions, D can be selected from the range of 8.1 mm to 7.8 mm. When the adjusting part 28 is operated, the diameter of the clamping part 26 can be adjusted, thereby allowing the clamp 200 to adapt to different models of external water pipes 24, facilitating installation and adjustment of clamping force.

[0047] In some examples, the inner diameter of the clamping part 26 can be 7.8 mm, 7.9 mm, 8.0 mm, 8.1 mm or other values ​​from 7.8 mm to 8.1 mm.

[0048] In some embodiments, the adjusting portion 28 extends radially along the clamping portion 26. This ensures that the adjusting portion 28 has sufficient operating space for easy operation.

[0049] Specifically, in Figure 6 In the illustrated embodiment, the adjusting portion 28 extends radially along the clamping portion 26, and the length of the adjusting portion 28 extending radially along the clamping portion 26 can be represented by L. In one example, L is 8.0 mm, thereby ensuring that the adjusting portion 28 has sufficient operating space for easy operation. It is understood that in other embodiments, the value of L can be other than 8.0 mm.

[0050] In some implementations, please refer to Figure 2 and Figure 3The clamping part 26 includes a first end 30, a connecting section 32, and a second end 34. The connecting section 32 connects the first end 30 and the second end 34. The adjusting part 28 includes a first adjusting member 36 and a second adjusting member 38. The first end 30 has an adjusting groove 40, and the second end 34 is at least partially accommodated in the adjusting groove 40. The first adjusting member 36 is connected to the first end 30, and the second adjusting member 38 is connected to the second end 34. When the first adjusting member 36 and the second adjusting member 38 move closer or further apart, the length of the portion of the second end 34 within the adjusting groove 40 is adjusted to adjust the clamping force of the clamping part 26. In this way, the clamping force of the clamping part 26 can be adjusted to ensure that the external water pipe 24 detaches from the water inlet pipe 18 when the pressure in the volume chamber 22 is greater than the set pressure.

[0051] Specifically, the first end 30, the connecting section 32, and the second end 34 are connected sequentially. The first end 30 has an adjustment groove 40, and the second end 34 is at least partially accommodated in the adjustment groove 40. The adjustment part 28 has a first adjustment member 36 and a second adjustment member 38. The first adjustment member 36 can be fixedly connected to the first end 30 along the radial extension direction of the clamping part 26, and the second adjustment member 38 can be fixedly connected to the second end 34 along the radial extension direction of the clamping part 26. Figure 6 In the illustrated embodiment, the included angle formed by the first adjusting member 36 and the second adjusting member 38 along the radial extension direction of the clamping portion 26 can be represented by K. In one example, under normal conditions, K can be 80 degrees. When the first adjusting member 36 and the second adjusting member 38 approach each other, the angle K decreases, which reduces the length of the second end 34 within the adjusting groove 40, thereby reducing the clamping force of the clamping portion 26. When the first adjusting member 36 and the second adjusting member 38 move away from each other, the angle K increases, which increases the length of the second end 34 within the adjusting groove 40, thereby increasing the clamping force of the clamping portion 26. It is understood that in other embodiments, the value of K can be adjusted according to specific circumstances, or it can be other values.

[0052] In some embodiments, the connecting section 32 has a through hole 42. This reduces the weight of the clamp 200 and saves material, while also making it easier to adjust the size of the clamping part 26.

[0053] Specifically, in Figure 4 In the illustrated embodiment, two through holes 42 are provided on the connecting segment 32, and the width of the connecting segment 32 can be represented by B. In one example, the width B can be 8.0 mm. By providing through holes 42, the weight of the clamp 200 can be reduced and materials can be saved. At the same time, it is also easier to adjust the size of the clamping part 26. It is understood that in other embodiments, the value of B can be other than 8.0 mm, and can be adjusted according to specific circumstances. The number, size, and shape of the through holes 42 are not specifically limited, as long as the structural strength of the clamp 200 is ensured.

[0054] In some implementations, please refer to Figure 2 One end of the connecting segment 32 connecting to the second end 34 has a supporting surface 44. Along the circumference of the clamping part 26, the supporting surface 44 is opposite to the first adjusting member 36. When the supporting surface 44 abuts against the first adjusting member 36, the second adjusting member 38 is at its longest length within the adjusting groove 40. In this way, the movement space of the second adjusting member 38 can be limited to ensure the maximum clamping force of the clamping part 26.

[0055] Specifically, one end of the connecting segment 32 connecting the second end 34 is formed with a supporting surface 44. Along the circumference of the clamping part 26, the supporting surface 44 is opposite to the first adjusting member 36. When the supporting surface 44 abuts against the first adjusting member 36, the second adjusting member 38 has the longest length in the adjusting groove 40, so that the diameter of the clamping part 26 is the smallest, thereby achieving the maximum clamping force of the clamping part 26.

[0056] In the illustrated embodiment, the first adjusting member 36 is provided with a groove 46. When the acute angle formed between the first adjusting member 36 and the second adjusting member 38 is reduced, the groove 46 provides a space for the second end 34 to move, which facilitates the position adjustment of the second end 34 and thus facilitates the adjustment of the clamping force of the clamping part 26.

[0057] In some embodiments, the water pump 12 and the steam generator 14 are arranged in a vertical direction. This facilitates the miniaturization of the steam generation system 100.

[0058] Specifically, in Figure 1 In the illustrated embodiment, the water pump 12 is positioned above the steam generator 14 near the rear of the steam generator 14. The water pump 12 and the steam generator 14 are arranged in a compact manner, reducing the lateral space occupied by the steam generation system 100, thereby facilitating the miniaturization of the steam generation system 100. In other embodiments, the water pump 12 may also be positioned below the steam generator 14; this is not specifically limited here.

[0059] In some implementations, please refer to Figure 1 The steam generator 14 has a steam outlet 48 at the top. This facilitates the return of condensate and improves the dryness of the steam at the steam outlet 48.

[0060] Specifically, the top of the steam generator 14 is provided with a steam outlet 48, which is located at the end of the steam generator 14 away from the water pump 12 and close to the front of the steam generator 14. The opening of the steam outlet 48 faces upward and the opening direction is perpendicular to the axial direction of the water inlet pipe 18. When the steam generator 14 heats water to generate steam, it can be discharged from the steam outlet 48, which is conducive to the return of condensate and improves the steam dryness of the steam outlet 48.

[0061] In some embodiments, the steam generator 14 includes a steam chamber 50 and a steam-water separation structure 52 that divides the steam chamber 50 into a first chamber 54 and a second chamber 56. The steam generator 14 has a steam outlet 48 that connects to the second chamber 56. A heating tube is installed in the first chamber 54. This helps to improve the problem of water spraying from the steam generator 14.

[0062] Specifically, in the illustrated embodiment, the steam generator 14 is provided with a steam chamber 50 and a steam-water separation structure 52. The steam-water separation structure 52 is located at one end of the steam generator 14 near the steam outlet 48. The steam-water separation structure 52 divides the steam chamber 50 into a first chamber 54 and a second chamber 56. The second chamber 56 is located below the steam outlet 48 and the steam outlet 48 is connected to the second chamber 56. The first chamber 54 is provided with a heating tube (not shown). The steam-water separation structure 52 has a plate 58 and multiple mesh holes (not shown) opened on the plate 58. The steam generator 14 heats water to generate steam in the first chamber 54. The steam passes through the mesh holes and enters the second chamber 56, and then exits through the steam outlet 48. When the steam passes through the plate 58 with mesh holes, water vapor can adhere to the plate 58 and form condensate. The condensate drips back into the first chamber 54, which helps to improve the water spraying problem of the steam generator 14.

[0063] An electrical appliance using steam according to an embodiment of this application includes the steam generating system 100 of any of the above embodiments.

[0064] The aforementioned steam-using electrical appliance uses a clamp 200 to tighten the external water pipe portion, sealing the external water pipe with the inlet pipe 18 and outlet pipe 20. Furthermore, the clamp 200 is configured to detach the external water pipe from the inlet pipe and / or outlet pipe when the pressure inside the volume chamber 22 exceeds the set pressure. This allows for pressure relief in case of abnormal internal pressure in the water pump 12, meeting safety requirements. This replaces the original pressure relief valve solution and facilitates the miniaturization of the water pump 12.

[0065] Specifically, steam-using appliances include, but are not limited to, cooking appliances, cleaning appliances, and range hoods. Cooking appliances can utilize steam for cooking and may include a cavity (not shown) and a steam generating system 100, which can be installed on the outer wall of the cavity. During cooking, the clamp 200 tightens the pipe portion 19 of the water inlet pipe 18, sealing the external water pipe 24 to the water inlet pipe 18. When the pressure inside the volume chamber 22 exceeds the set pressure, the external water pipe 24 detaches from the water inlet pipe 18, and the water pump 12 delivers water to the steam generator 14. The steam generator 14 converts the water into steam, which is then introduced into the cooking cavity to heat the food inside.

[0066] During cleaning, the cleaning appliance can use steam for cleaning. For example, when cleaning the impeller of a range hood, the cleaning appliance can heat water to generate steam through the steam generator 14. The steam can be introduced to the impeller of the range hood, thereby cleaning away the grease on the impeller.

[0067] A steam generating system 100 can be installed on the range hood. The steam generated by the steam generating system 100 can perform steam cleaning on the impeller, volute and other components inside the range hood.

[0068] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0069] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
