Description

Technical Field

[0001] This utility model relates to the field of cookware, and in particular to a jet structure for preventing overflowing pots. Background Technology

[0002] The applicant's prior patent "2025200773516" discloses a rice cooker with an anti-overflow function. In that patent, the rice cooker has a first flexible hose, a second flexible hose, and a miniature blower connected to the first and second flexible hoses. When overflow occurs, the blower activates, and the first and second flexible hoses blow air into the pot to reduce the overflow. While this airflow method does reduce the overflow, the uneven airflow results in a less effective mitigation of the overflow problem. Summary of the Invention

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a jet structure for preventing overflow in pots. By setting nozzles, the uniformity of airflow is improved, further enhancing the effect of preventing overflow.

[0004] The technical solution of this utility model is implemented as follows: An air jet structure for preventing overflow of a rice cooker includes an air inlet pipe and a nozzle. The air inlet pipe is vertically connected to the bottom surface of the rice cooker lid and its upper end is connected to a miniature blower. The lower end of the air inlet pipe is connected to the nozzle. The nozzle has a cavity and a plurality of exhaust hole groups are provided on the side of the nozzle facing the inner pot of the rice cooker. The exhaust hole groups include a plurality of air holes spaced apart from bottom to top.

[0005] In this solution, when overflow occurs, the miniature blower starts, and airflow enters the nozzle from the outside. The airflow is blown out from each air hole of the nozzle's exhaust port group. At this time, the airflow is evenly distributed in the pot. The even airflow better reduces the temperature of the boiling water surface in the pot, and at the same time breaks the bubbles generated by the boiling rice water, thereby achieving the function of preventing overflow.

[0006] Preferably, the nozzle is located on the axis of the inner pot of the rice cooker. Positioning the nozzle directly above the inner pot facilitates the even distribution of airflow throughout the inner pot.

[0007] Preferably, the air intake pipe and the nozzle are integrally molded. This facilitates the use of molds to produce the jet structure, resulting in advantages such as low production cost and ease of promotion.

[0008] Preferably, the nozzle is spherical, having an upper hemisphere and a lower hemisphere defined with reference to the equatorial plane.

[0009] Preferably, the plurality of exhaust port groups are arranged in an array on the lower hemisphere with the intake pipe axis as the center.

[0010] Preferably, the diameter of the plurality of pores gradually decreases from bottom to top.

[0011] Preferably, the nozzle is cubic in shape, and the plurality of exhaust port groups are located on the bottom surface and four side walls of the nozzle.

[0012] Preferably, the air intake pipe and nozzle are made of polypropylene or polyamide.

[0013] Preferably, the outer peripheral surface of the air intake pipe is provided with a sturdy component for improving the stability of the jet structure.

[0014] Preferably, the stabilizing component includes a bushing fitted onto the intake pipe, with an elastic gasket provided between the bushing and the intake pipe.

[0015] The principle and beneficial effects of this utility model that adopts the above technical solution are as follows: Compared with the prior application, the airflow blown out by the nozzle is evenly distributed in the inner pot of the rice cooker, which can better eliminate the bubbles generated by boiling when overflow occurs; by setting multiple air holes with the aperture gradually decreasing from bottom to top, it is further ensured that the airflow blown out by each air outlet reaches the boiling water surface at a consistent speed.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] The specific implementation of this utility model is as follows: Example

[0021] like Figures 1 to 3 As shown, this utility model provides a jet structure for preventing overflow of rice cookers. The jet structure 1 includes an air inlet pipe 2 and a nozzle 3. The air inlet pipe 2 is vertically connected to the bottom surface of the rice cooker lid 7 and its upper end is connected to a micro blower. The lower end of the air inlet pipe 2 is connected to the nozzle 3. The nozzle 3 has a cavity. The side of the nozzle 3 facing the inner pot of the rice cooker is provided with a plurality of exhaust hole groups. The exhaust hole groups include a plurality of air holes 4 spaced apart from bottom to top.

[0022] In this solution, when overflow occurs, the miniature blower is activated, and airflow enters the nozzle 3 from the outside. The airflow is blown out from each air hole 4 of the exhaust hole group of the nozzle 3. At this time, the airflow is evenly distributed in the pot. The even airflow better reduces the temperature of the boiling water surface in the pot, and at the same time breaks the bubbles generated by the boiling rice water, thereby achieving the function of preventing overflow.

[0023] Nozzle 3 is located on the axis of the inner pot of the rice cooker. Nozzle 3 is positioned directly above the inner pot of the rice cooker, which facilitates the even distribution of airflow throughout the inner pot.

[0024] Furthermore, in this embodiment, the nozzle 3 is spherical, having an upper hemisphere and a lower hemisphere defined by a reference to the equatorial plane. Multiple exhaust port groups are arrayed on the lower hemisphere with the axis of the air inlet pipe 2 as the center. The diameter of the multiple air holes 4 gradually decreases from bottom to top. Understandably, the air hole 4 located at the bottom of the sphere is closest to the boiling water surface, while the air hole 4 located at the top of the sphere is farthest from the boiling water surface. The air holes 4 closer to the boiling water surface have larger diameters and slower airflow velocity at their outlets, while the air holes 4 farther from the boiling water surface have smaller diameters and faster airflow velocity at their outlets. This arrangement ensures that the airflow from the air holes 4 at different positions reaches the boiling water surface at a basically consistent speed.

[0025] The outer circumferential surface of the air intake pipe 2 is provided with a stabilizing component for improving the stability of the jet structure 1; the stabilizing component includes a bushing 5 sleeved on the air intake pipe 2, and an elastic gasket 6 is provided between the bushing 5 and the air intake pipe 2. In this embodiment, the bushing 5 is fixedly connected to the bottom surface of the rice cooker lid 7, and the elastic gasket 6 is made of bent steel sheet.

[0026] In this embodiment, the air intake pipe 2 and the nozzle 3 are made of polypropylene or polyamide and are integrally molded. This facilitates the production of the jet structure 1 using molds, resulting in low production costs and ease of promotion. Example

[0027] The difference between this implementation method and Example 1 is that: Figure 4As shown, the nozzle 3 is cubic in shape, with multiple exhaust hole groups located on the bottom surface (not shown) and four side walls of the nozzle 3. In this embodiment, the nozzle 3 is a regular cube. It should be noted that the shape of the nozzle 3 can be regular as long as it is not spherical or cubic. It can also be an ellipsoid or a polygon. There are no restrictions here. In actual production, the appropriate shape of the nozzle 3 is selected according to the requirements.

[0028] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
