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

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a rice noodle roll steamer includes a furnace body 1 and a diffuser head 2. The furnace body 1 has a hollow structure, and its top is provided with an upward-opening steam chamber 12. The bottom wall of the steam chamber 12 is provided with a drain outlet 13 and a steam inlet. The water condensed in the steam chamber 12 will be discharged into a water tank through the drain outlet 13 for water treatment and recycling. The steam inlet is centrally located on the bottom wall of the steam chamber 12, and the diameter of the steam inlet is less than 3 cm, preferably less than 2 cm in this embodiment. The lower end of the steam inlet is connected to a steam source, and the upper end of the steam inlet is provided with an internal thread. The diffuser head 2 has a hollow structure, and the lower end of the diffuser head 2 is connected to a threaded pipe 21. The threaded pipe 21 is threadedly connected to the upper end of the steam inlet. Several steam outlet holes 22 are provided on the side wall, and these holes 22 are evenly distributed around the circumference of the diffuser head 2. In use, a white cloth rack for steaming rice noodle rolls can be placed at the opening of the steam chamber 12 through a breathable steam rack. When steam flows into the diffuser head 2 through the steam inlet, the smaller diameter steam inlet will increase the steam flow rate through it under the condition that the air source pressure remains unchanged. At the same time, the diffuser head 2 is tightly connected to the upper end of the steam inlet through the threaded pipe 21, which avoids air leakage. This increases the steam velocity flowing out of the steam outlet holes 22 of the diffuser head 2, making the effective diffusion area of ​​steam in the steam chamber 12 larger and the diffusion more uniform, thus improving the steaming effect of rice noodle rolls.

[0028] Specifically, the steam source can be a steam generator built into the furnace body 1. The steam generator can be purchased through market channels, and will not be described in this embodiment.

[0029] Furthermore, a boss 11 is welded to the center of the upper side wall of the furnace body 1, and the steam chamber 12 is set on the boss 11 with its opening facing upward. Compared with directly machining the steam chamber 12 on the furnace body 1, assembling the boss 11 and the furnace body 1 by welding can reduce the production cost of the steam chamber 12 and improve economic efficiency.

[0030] Furthermore, the upper side wall of the boss 11 is provided with a rim 15, which encloses the opening of the steam chamber 12. The inner side wall of the rim 15 is spaced from the opening of the steam chamber 12. When steaming the rice noodle roll raw material placed at the opening of the steam chamber 12, the lid can be supported by the upper side wall of the boss 11 and the lid can be inverted on the inner side of the rim 15 to reduce the heat loss of steam and improve the steaming efficiency. At the same time, the water condensed by the steam will be confined to the inner side of the rim 15 and eventually flow back into the steam chamber 12 through the gap and be discharged from the drain outlet 13.

[0031] Furthermore, the diffuser head 2 is cylindrical, and a flange 23 is provided at the upper end of the side wall of the diffuser head 2. The flange 23 is arranged along the circumference of the diffuser head 2. After the steam is ejected from the steam outlet 22, it will flow horizontally along the lower side wall of the flange 23 so as to guide the steam to diffuse horizontally through the flange 23, avoid the steam from concentrating in the middle of the steam chamber 12, and make the steam diffuse more evenly in the steam chamber 12.

[0032] Furthermore, the rice noodle roll maker also includes a steam inlet pipe 3. The bottom wall of the steam chamber 12 is provided with an installation port 14 that connects to its inner cavity. The steam inlet pipe 3 is fixedly fitted inside the installation port 14. The inner cavity of the steam inlet pipe 3 forms a steam inlet. The lower end of the steam inlet pipe 3 is connected to the steam source. The threaded pipe 21 is threaded into the upper end of the steam inlet pipe 3. Compared with directly opening a threaded hole in the middle of the steam chamber 12, processing the steam inlet pipe 3 and the furnace body 1 separately and then assembling them, the cost is lower and the economic efficiency can be improved.

[0033] Furthermore, the rice noodle roll steamer also includes a steaming plate 4. Four support blocks 5 are provided on the inner wall of the steam chamber 12. The four support blocks 5 are distributed circumferentially at the four corners of the steam chamber 12. The steaming plate 4 is horizontally nested at the upper end of the steam chamber 12. The four corners of the lower side wall of the steaming plate 4 abut against the adjacent support blocks 5 respectively. Several exhaust holes 41 are evenly distributed on the steaming plate 4, which penetrate the upper and lower side walls.

[0034] Furthermore, the rice noodle roll oven also includes a frame 6, which is laid flat on the upper side wall of the steaming plate 4 and encloses several steam vents 41.

[0035] In this embodiment, when using it, first lay the white cloth on the upper side wall of the frame 6, and make the middle of the white cloth concave towards the inside of the frame 6. Then add the rice paste and ingredients into the concave part of the white cloth to steam the rice noodle roll. The steam diffused in the steam chamber 12 will be released to various parts of the white cloth through several steam vents 41, thereby evenly heating the rice paste and other ingredients located inside the frame 6.

[0036] Furthermore, a handle 42 is provided at one end of the upper side wall of the steaming plate 4 so that the user can take the steaming plate 4.

[0037] Furthermore, the support block 5 is provided with a connecting hole 51 that passes through its upper side wall and lower side wall. When the customer needs to fix the steam plate 4, holes can be pre-drilled at the four corners of the steam plate 4. Screws can be passed through the pre-drilled holes at the corners of the steam plate 4 and screwed into the corresponding connecting holes 51, thereby fixing the steam plate 4 at the opening of the steam chamber 12.

[0038] Furthermore, pads 7 are provided at the four corners of the lower side wall of the furnace body 1.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; conversely, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
