The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0028] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-4 The following are examples provided by the present invention.

[0031] The embodiment of the present invention provides a dim sum oven, comprising: a stove frame 10, a high-pressure steam tank 20 and a steam outlet platform 30; the high-pressure steam tank 20 is arranged in the stove frame 10, and the steam outlet platform 30 is arranged on the top of the stove frame 10, and the high-pressure steam tank 20 is connected to the steam outlet platform 30. The high-pressure steam tank 20 is used to generate high-temperature water vapor and transport it to the steam outlet platform 30. The steam outlet platform 30 is used to hold a steamer with food placed on it and transport the high-temperature water vapor into the steamer, so as to steam various foods in the steamer. The steamer can be a conventional bamboo or wooden steamer, and it is only necessary to ensure that the size of the steamer cannot exceed the size of the steam outlet platform 30. Among them, the high-pressure steam tank 20 is respectively provided with a heating device 21, a steam outlet pipe 22 and a water inlet 23. The water inlet 23 is used to inject water into the high-pressure steam tank 20. The heating device 21 is used to heat the water in the high-pressure steam tank 20 and generate high-temperature water vapor. The steam outlet pipe 22 is connected to the steam outlet platform 30 to transport the water vapor to the steam outlet platform 30; the steam outlet pipe 22 is respectively provided with a pressure regulating switch 26 and a pressure gauge 27. The pressure regulating switch 26 is electrically connected to the pressure gauge 27 and the heating device 21 respectively. The pressure gauge 27 is used to monitor the air pressure in the high-pressure steam tank 20 and the steam outlet pipe 22. The pressure regulating switch 26 can adjust the heating power of the heating device 21 according to the air pressure data monitored by the pressure gauge 27, so that the internal air pressure of the high-pressure steam tank 20 is maintained at a state higher than one standard atmospheric pressure.

[0032] When the dim sum oven is in operation, the heating device 21 can heat the water in the high-pressure steam tank 20 and continuously generate high-temperature steam. The increase in water vapor causes the air pressure in the high-pressure steam tank 20 to continuously increase, thereby causing the temperature of the water vapor to continuously increase until the air pressure in the high-pressure steam tank 20 reaches a pressure range preset by the pressure gauge 27. When the air pressure in the high-pressure steam tank 20 continues to increase and exceeds the preset pressure range, the pressure regulating switch 26 can control the heating device 21 to reduce or stop heating, thereby reducing the air pressure in the high-pressure steam tank 20 to the preset pressure range. When the air pressure in the high-pressure steam tank 20 is lower than the preset pressure range, the pressure regulating switch 26 can control the heating device 21 to turn on or increase the power, thereby raising the air pressure in the high-pressure steam tank 20 to the preset pressure range, so that the internal air pressure of the high-pressure steam tank 20 is maintained at a level higher than standard atmospheric pressure, thereby enabling the high-pressure steam tank 20 to continuously output higher temperature steam, thereby improving the efficiency of steaming food. As for the temperature of the water vapor, it can be set by changing the preset range of the pressure gauge to meet different steaming requirements.

[0033] Furthermore, a liquid level probe 24 is provided downwardly through the top of the high-pressure steam tank 20, and a booster water pump 231 is connected to the water inlet 23. Since the air pressure in the high-pressure steam tank 20 is relatively high, a booster water pump 231 is required to inject water into the high-pressure steam tank 20. The liquid level probe 24 is electrically connected to the booster water pump 231. The liquid level probe 24 is used to monitor the water level in the high-pressure steam tank 20. The booster water pump 231 can adjust the water intake according to the water level monitored by the liquid level probe 24. An electromagnetic valve can be provided on the booster water pump 231 to control the water circuit switch. The liquid level probe 24 can transmit the water surface height information in the high-pressure steam tank 20 to the booster water pump 231. The electromagnetic valve can open the valve to release water or close the valve to stop water according to the water level information detected by the liquid level probe 24, so that the water level in the high-pressure steam tank 20 is always maintained within an appropriate range. In addition, a water outlet 25 is provided at the bottom of the high-pressure steam tank 20, and a solenoid valve is also provided at the water outlet 25. During normal use of the dim sum stove, the solenoid valve closes the water outlet 25. When the dim sum stove needs to be shut down or repaired, the residual water in the high-pressure steam tank 20 can be discharged from the water outlet 25.

[0034] Furthermore, the steam outlet pipe 22 is connected to a pressure relief valve 28, which is electrically connected to the pressure gauge 27. The pressure relief valve 28 is primarily intended to prevent accidents such as the high-pressure steam tank 20 or the steam outlet pipe 22 from bursting due to a malfunction or damage to the pressure gauge or pressure regulating switch. Of course, the pressure relief valve 28 can also relieve pressure when the pressure gauge 27 detects that the pressure within the high-pressure steam tank 20 exceeds a preset upper limit.

[0035] Furthermore, the steam outlet platform 30 includes a turntable 31 and an annular limiting enclosure 32. A plurality of support rollers 11 are provided on the top of the grate 10. The support rollers 11 can also be replaced by support bearings. The number of support rollers 11 is at least three. The plurality of support rollers 11 are located on the same circumference, and the center of the circle coincides with the center of the turntable 31. The plurality of support rollers 11 are respectively connected to the bottom rolling support of the turntable 31, so that the turntable 31 can rotate horizontally relative to the grate 10. In order to facilitate rotation, the steam outlet platform 30 is generally circular, and the support rollers 11 are generally supported at the bottom of the turntable 31 near the edge. The strength of the turntable 31 itself and the support rollers 11 itself needs to be high enough to withstand the total weight of the steamer and the food in the steamer without easily deforming or even collapsing. When the user uses the dim sum oven provided in this embodiment to steam food, he only needs to stack the steamers layer by layer in the middle of the steam outlet platform 30. The high-pressure steam tank 20 can provide a steady stream of high-temperature water vapor to the steamer through the steam outlet platform 30 to slowly steam the food. When the user wants to take out the food in a certain layer of the steamer, he only needs to lift a corner of the steamer as usual. If he needs to take out the food relatively close to the inside of the steamer, he only needs to gently rotate the steam outlet platform 30 to rotate the steamer together, turn the corresponding food to the side close to him, and then lift the steamer to take it out. It is very labor-saving and easy to use.

[0036] In addition, a limiting panel 32 is concentrically arranged at the bottom of the turntable 31 and close to the edge of the turntable 31. The limiting panel 32 surrounds the outside of the support roller 11. The edge of the turntable 31 that exceeds the limiting panel 32 can be used by the user to exert force to rotate the turntable 31. A number of handles can also be provided on the outer wall of the limiting panel 32 so that the user can more conveniently rotate the entire steam outlet platform 30. It can be understood that the role of the limiting panel 32 is to prevent the turntable 31 from derailing. The limiting panel 32 is combined with the turntable 31 to form a shape similar to a bottle cap. The support roller 11 is located on the inner side of the limiting panel 32 but not far away from the limiting panel 32. Even if the axis of the turntable 31 deviates, the support roller 11 can block the limiting panel 32, so that the turntable 31 will not deviate significantly in the horizontal direction. In addition, the bottom of the limiting plate 32 should be higher than the top surface of the grate 10, so that the limiting plate 32 can rotate along the site with the turntable 31; furthermore, you can also choose to set another circle of limiting plates 32 on the inner side of the supporting roller 11, and clamp the supporting roller 11 between the two layers of limiting plates 32, which can further stabilize the rotation of the turntable 31.

[0037] Furthermore, an annular support plate 12 is provided on the top of the furnace frame 10, and the outer diameter of the support plate 12 is smaller than the inner diameter of the limiting enclosure 32. A plurality of support rollers 11 are evenly arranged on the inner side wall of the support plate 12 along the circumferential direction of the support plate 12, so that when the turntable 31 deviates in a small range, the limiting enclosure 32 first contacts the outer side wall of the support plate 12, and the friction force between the two relatively smooth curved surfaces is smaller than the friction force between the support rollers 11 and the inner side wall of the limiting enclosure 32, which can reduce the friction resistance encountered by the turntable 31 when it rotates; it is worth noting that It is worth mentioning that the upper end of the support roller 11 is higher than the upper edge of the support plate 12, so that the support plate 12 and the bottom of the turntable 31 are not in contact as much as possible to avoid increasing the rotation resistance of the turntable 31. However, the upper end of the support roller 11 is only slightly higher than the upper edge of the support plate 12, for example, 3mm, 5mm higher, etc. The provision of the support plate 12 can enhance the supporting strength of the support roller 11. Even if the support roller 11 suddenly cannot withstand the pressure of the turntable 31, the support plate 12 can provide a bottom to prevent the turntable 31 from being significantly deformed and collapsed.

[0038] Specifically, the end of the steam outlet pipe 22 is connected to a branch pipe 29, and several steam pipes 291 (not fully shown in the accompanying drawings) are respectively connected to the branch pipe 29. Several steam outlet holes 33 are evenly distributed on the turntable 31. The steam outlet holes 33 are located on the inner side of the support plate 12. Several steam pipes 291 are connected to several steam outlet holes 33 in a one-to-one correspondence, and are used to output high-temperature water vapor to the steamer above the turntable 31. The steam pipe 291 can adopt a hose made of high-temperature resistant and environmentally friendly material. Even if the steam outlet holes 33 rotate with the turntable 31, the steam pipe 291 will not easily detach from the steam outlet holes 33. Furthermore, a limit pin 13 is provided on the grate 10, and a baffle 35 is connected to the bottom of the steam outlet platform 30. The baffle 35 is rotatably abutted against the limit pin 13, and is used to limit the rotation range of the steam outlet platform 30 to within 360°, so that the turntable 31 can only rotate less than one circle in the forward or reverse direction at most, which can prevent the hose from getting tangled or pulled against each other and causing it to detach from the steam outlet hole 33.

[0039] Furthermore, a reinforcing piece 34 is provided at the bottom of the turntable 31 away from the steam outlet 33. The reinforcing piece 34 is triangular and is used to prevent the turntable 31 from being deformed by pressure. It can further improve the supporting strength of the turntable 31 and prevent the middle part of the turntable 31 from sinking or collapsing.

[0040] Furthermore, a water retaining strip 14 is provided on the top edge of the grate 10, and a plurality of drainage holes 15 are provided on the inner side of the water retaining strip 14. The bottom of the drainage hole 15 is connected to a water collecting trough 16. The water retaining strip 14 can prevent the water droplets condensed on the top surface of the grate 10 when water vapor is cold from dripping onto the ground, and can gather these water droplets and discharge them into the water collecting trough 16 through the drainage holes 15, and then use a drainage pipe to connect with the water collecting trough 16 to drain or recycle the water.

[0041] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein.
