Description

Technical Field

[0001] This utility model relates to the technical field of heating components for household appliances, and in particular to a novel dual heating element. Background Technology

[0002] Glass kettles (health kettles) are widely used in daily life due to their transparency, aesthetics, and practicality. Among them, small-sized glass kettles are a common choice for brewing herbal tea due to their compact size and suitability for single use, occupying an important market share. Their core heating component is the bottom heating plate. Currently, the heating plates of small-sized products on the market generally adopt a single heating tube structure, which can only realize the function of boiling water. If a stable heat preservation is required, an insulation structure needs to be added. Most existing small-sized glass kettles use PTC insulation elements and electronic insulation. PTC insulation elements have low efficiency and poor insulation effect, and it is difficult to maintain the target temperature stably. Electronic insulation can control the temperature, but there are still problems with temperature fluctuation and noise. In addition, an extra thermostat is required, which is also more expensive.

[0003] The most suitable solution is to add an extra heating element to the lower heating plate, achieving both boiling and heat preservation through dual heating elements. This provides stable temperature control, eliminates recurring noise, and generates steam. However, small-sized heating plates are generally around 130mm in size, and they typically employ a downward-curving structure to accommodate glass kettle bodies. This concave structure compresses the heating plate space, leaving insufficient room for a second heating element. Changing the heating plate size would require simultaneous adjustments to the kettle body and other components, necessitating the replacement of the entire production line's molds and equipment, resulting in high modification costs and significant economic pressure. Therefore, a structure is needed that allows for dual heating element installation without altering the core specifications of existing products and production lines, thereby improving heating efficiency and reducing modification costs. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a novel dual-heating-tube system. This system solves the problems of low heating efficiency of a single heating tube in a glass kettle heating plate and excessively high costs due to the need to change the chassis specifications when adding heating tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel dual-heating-tube design includes a main chassis and a heating assembly. The main chassis has an assembly portion on its upper part for connecting to a glass pot body. The bottom of the main chassis has a planar area for mounting at least two heating tubes. The planar area covers the bottom position of the main chassis corresponding to the assembly portion. The heating assembly carries at least two heating tubes and is mounted on the planar surface at the bottom of the main chassis for heating the main chassis.

[0006] Preferably, the assembly part includes an assembly ring, which is located above the main chassis and connected to the main chassis. The main chassis and the assembly ring cooperate to form an assembly space for inserting the glass pot body. The assembly ring and the main chassis cooperate to form an assembly space, providing positioning for the insertion of the glass pot body, and the lower end of the glass pot body can be inserted into the assembly space.

[0007] Preferably, the main chassis edge is provided with a first mating part, and the assembly ring is provided with a second mating part. The first mating part and the second mating part enclose an assembly space, forming a glue-applying groove. The glue-applying groove enclosed by the two parts allows the lower end of the glass pot body to be inserted and stably fixed.

[0008] Preferably, the assembly ring is provided with a connecting part, and is fixedly connected to the main chassis through the connecting part. The connecting part can be welded to ensure a firm connection between the assembly ring and the chassis, preventing loosening after long-term use.

[0009] Preferably, the heating assembly includes a first connection terminal and a second connection terminal. The two heating tubes in the heating assembly are used for heating water and keeping it warm, respectively. The first connection terminal and the second connection terminal are respectively located at the two ends of the two heating tubes. The two heating tubes respectively undertake the functions of heating water and keeping it warm, thus meeting the dual requirements of rapid heating and stable heat preservation for small glass kettles.

[0010] Preferably, one end of each of the two heating tubes is connected to a common connection terminal 1, and the other end is connected to two separate connection terminals 2. This connection method, in which one end is connected to the common connection terminal 1 and the other end is connected to the two separate connection terminals 2, allows the two heating tubes to be controlled independently.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention features a flat bottom design for the main chassis, covering the corresponding area below the assembly section. This design eliminates the traditional concave structure, providing ample installation space for the dual heating elements without altering the size of the main chassis. It is compatible with existing production lines, avoiding mold replacement costs. The assembly ring and main chassis work together to form a glue-applying groove, which, along with the welded connection, ensures a secure and sealed installation of the glass kettle, improving reliability. The two heating elements in the heating assembly have distinct functions: heating and boiling water, and maintaining the temperature. Mechanical heat preservation reduces costs and avoids noise from repeated heating, meeting the dual needs of rapid heating and stable heat preservation for small-sized glass kettles. It is cost-effective and practical. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] Example: Please see Figs. 1-3A novel dual-heating-tube design includes a main chassis 1 and a heating assembly 2. The main chassis 1 has an assembly section on top for connection to a glass kettle body. The bottom of the main chassis 1 has a planar area for mounting at least two heating tubes, covering the bottom of the main chassis 1 corresponding to the assembly section. The heating assembly 2 carries at least two heating tubes and is mounted on the planar surface at the bottom of the main chassis 1 for heating the main chassis 1. The main chassis 1 serves as the foundational support component of the entire heating tube structure. Its bottom is designed as a planar surface for mounting at least two heating tubes. This planar design abandons the traditional recessed structure, providing ample space for the installation of dual heating tubes without altering the overall specifications of the main chassis 1, ensuring compatibility with existing glass kettles and production lines. The main chassis 1 provides a planar surface at the bottom for mounting two heating tubes, abandoning the traditional recessed structure, and providing sufficient installation space for dual heating tubes within the limitation of a main chassis 1 with a size of 130mm or less.

[0020] The assembly part includes an assembly ring 3, which is located above and connected to the main chassis 1. The edge of the main chassis 1 has a mating part 11, and the assembly ring 3 has a mating part 31. The mating parts 11 and 31 together form an assembly space, constituting a glue-applying groove 41. The main chassis 1 and the assembly ring 3 fit together to form the glue-applying groove 41 for inserting the glass body. The lower end of the glass body is assembled with the assembly components and then sealed. The mating part 11 is a structure on the edge of the main chassis 1 and can be manufactured using a stamping process. The assembly ring 3 is integrally formed with the main chassis 1. During the processing of the main chassis 1, the edge of the chassis is stamped and bent using a stamping die to form the mating part 11 of the required shape. The mating part 11 and the main chassis 1 are an integral whole, with high connection strength, no need for additional connection process, high production efficiency, and can ensure the relative positional accuracy of the mating part 11 and the main chassis 1. The assembly ring 3 is provided with a connecting part 32, and is fixedly connected to the main chassis 1 through the connecting part 32. The connecting part 32 can be welded to the main chassis 1.

[0021] The heating component 2 includes a first connection terminal 21 and a second connection terminal 22. The two heating tubes in the heating component 2 are used for heating water and keeping it warm, respectively. The first connection terminal 21 and the second connection terminal 22 are respectively located at the two ends of the two heating tubes. The two heating tubes respectively undertake the functions of heating water and keeping it warm, which meets the dual needs of rapid heating and stable heat preservation for small glass kettles.

[0022] The heating element 2 is equipped with two heating tubes. One of them can be a high-power heating tube, used to quickly heat the water to boiling, and the other can be a low-power heating tube, used for the heat preservation stage after boiling, to maintain the water temperature at a stable temperature between 95°C and 100°C. One end of the two heating tubes is connected to a common terminal 21 to form a common circuit terminal, and the other end is connected to two independent terminals 22 to form independent control terminals. When boiling water, the connection terminal 22 corresponding to the high-power heating tube is turned on to achieve rapid heating. When keeping warm, it can switch to the connection terminal 22 corresponding to the low-power heating tube to be turned on for heat preservation after boiling. Through continuous low heat output, the water temperature is stably maintained between 95°C and 100°C, and a small amount of steam is generated, which is suitable for the needs of brewing flower tea.

[0023] Without altering the overall dimensions of the main chassis 1 and the glass kettle, this design achieves low-cost mechanical heat preservation in a small-sized product through the functional division and optimized spatial layout of the dual heating elements. This avoids the high costs associated with replacing production line molds and solves the problems of high cost and repeated heating associated with electronic and PTC heat preservation. Furthermore, the continuous output of a small amount of steam during heat preservation provides a suitable environment for brewing herbal tea, further enhancing the quality of the beverage and the user experience.

[0024] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
