Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a stable and reliable all-glass heating kettle. Background Technology
[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.
[0003] Currently, all-glass heating kettles avoid the problem of heavy metal residue caused by stainless steel heating, which is more beneficial to drinking water health and is therefore gradually gaining popularity.
[0004] Due to the inherent properties of glass, glass kettles are easily damaged if not used according to specifications. One major cause of damage is breakage from external impact, while another more common cause is uneven heating during the heating process, leading to the kettle shattering. For example, in most all-glass kettles on the market, the heating element is typically located at the bottom of the kettle. When water begins to boil, the bottom of the kettle heats up rapidly, while the side walls remain relatively cool. When the temperature difference exceeds a certain threshold (usually 180°C), the kettle will crack or shatter, posing a safety hazard. Utility Model Content
[0005] To overcome the defects described in the prior art, this utility model provides a stable and reliable all-glass heating kettle. By setting a first temperature probe and a second temperature probe to detect the temperature of the bottom and side of the all-glass kettle body respectively, when the temperature difference between the two exceeds a preset temperature difference value, the control board will control the heating module to reduce power or stop working, thereby preventing the glass kettle body from cracking or exploding, and thus ensuring the stable and reliable use of the product.

[0041] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0042] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0044] See Figure 1-3This utility model provides a stable and reliable all-glass heating kettle, including an all-glass kettle body 1 and a heating module 2 disposed at the bottom of the all-glass kettle body 1 for heating the all-glass kettle body 1; wherein, the heating module 2 includes a heating plate attached to the bottom of the all-glass kettle body 1 for heat transfer and a heating tube 203 disposed at the bottom of the heating plate for heating thereon, the heating plate being used to completely cover the bottom of the all-glass kettle body 1; in addition, the all-glass kettle body 1 also includes a first temperature probe 3, a second temperature probe 4 and a control board 5, the control board 5 being electrically connected to the first temperature probe 3, the second temperature probe 4 and the heating tube 203 respectively; specifically, the first temperature probe 3 abuts against the bottom of the heating plate to detect temperature, thereby obtaining the temperature of the bottom of the all-glass kettle body 1; the second temperature probe 4 abuts against the side of the all-glass kettle body 1 to detect temperature, thereby obtaining the temperature of the bottom of the all-glass kettle body 1.
[0045] Specifically, when the temperature difference between the temperature detected by the first temperature probe 3 and the temperature detected by the second temperature probe 4 is greater than 150°C, the control board 5 controls the heating tube 203 to reduce its power; subsequently, if the temperature difference is greater than 180°C, the control board 5 will directly stop the heating tube 203 from working to prevent dry burning.
[0046] Therefore, by setting a first temperature probe 3 and a second temperature probe 4, the first temperature probe 3 is used to detect the temperature of the heating plate to obtain the temperature of the bottom of the all-glass kettle body 1, and the second temperature probe 4 is used to detect the temperature of the side of the all-glass kettle body 1. When the temperature difference between the two exceeds the preset temperature difference value, the control board 5 will control the heating module 2 to reduce the power or stop working, thereby avoiding the situation of the all-glass kettle body 1 cracking or exploding, and thus ensuring the stable and reliable use of the product.
[0047] Of course, it should be noted that in other embodiments, the temperature difference can also be set between 140℃ and 200℃, which can be adjusted according to the actual situation and is not limited here.
[0048] In addition, the heating plate completely covers the bottom of the all-glass kettle body 1. Compared with the traditional glass kettle where the temperature probe passes through the heating plate and is placed against the bottom of the all-glass kettle body 1 to detect the temperature, this not only ensures the uniformity of heating the bottom of the glass kettle body and prevents it from cracking due to uneven heating, but also improves the heating efficiency and thus speeds up the boiling process.
[0049] In this embodiment, both the first temperature probe 3 and the second temperature probe 4 are NTC.
[0050] Specifically, when the temperature detected by the first temperature probe 3 is greater than the first preset temperature (in this embodiment, the first preset temperature is 230°C), the control board 5 controls the heating element 203 to stop working to avoid dry burning. Additionally, the all-glass kettle also includes a third temperature probe (not shown in the figure), which is attached to the bottom of the heating element 203 to detect temperature. When the temperature detected by the third temperature probe is greater than the second preset temperature (in this embodiment, the second preset temperature is 260°C), the control board 5 controls the heating element 203 to stop working.
[0051] Therefore, when the temperature of the heating plate exceeds the first preset temperature, the control board 5 will control the heating tube 203 to stop working; when the temperature of the heating tube 203 exceeds the second preset temperature, the control board 5 will also control the heating tube 203 to stop working, thereby preventing the all-glass kettle body 1 from dry burning, and further improving the reliability of the product.
[0052] Of course, it should be noted that in other embodiments, the maximum operating temperature of the heating plate can be limited to between 200°C and 250°C, and the maximum operating temperature of the heating tube 203 can be limited to between 250°C and 290°C. Users can adjust these temperatures according to actual conditions, and no restrictions are imposed here.
[0053] See Figure 2-3 Specifically, the heating plate includes a first heating plate 201 and a second heating plate 202 stacked on top of the first heating plate 201. The second heating plate 202 is attached to the bottom of the all-glass pot body 1 to achieve heat transfer. The heating tube 203 is disposed at the bottom of the first heating plate 201 to achieve heating. The first temperature probe 3 abuts against the bottom of the first heating plate 201 to achieve temperature detection.
[0054] Furthermore, it also includes a heat insulation cover 7 located below the heating module 2. The heat insulation cover 7 uses an elastic member 8 to press and fix the heating plate to the bottom of the all-glass kettle body 1. A mounting post 204 is riveted to the first heating plate 201. The heat insulation cover 7 has mounting holes 701 corresponding to the mounting posts 204. A screw hole is provided inside the mounting post 204. A screw 9 passes through the mounting post 204 and the mounting hole 701 to achieve connection and fixation.
[0055] In this embodiment, a mounting bracket 301 is also included, which is mounted on the heat insulation cover 7, and the first temperature probe 3 is mounted on the mounting bracket 301.
[0056] The elastic element 8 is a spring, which is sleeved on the mounting post 204 with one end abutting against the first heating plate 201 and the other end abutting against the heat insulation cover 7. Thus, under the action of the spring, the first heating plate 201 and the second heating plate 202 can be moved upward in sequence and abut against the bottom of the all-glass pot body 1 to achieve heat transfer.
[0057] In this embodiment, the second heating plate 202 is stacked on top of the first heating plate 201 and covers the riveting joint between the first heating plate 201 and the mounting post 204, thereby improving the aesthetics of the bottom of the all-glass kettle body 1.
[0058] Furthermore, it also includes a fixing ring 6 fitted around the outer periphery of the bottom of the all-glass kettle body 1; specifically, the all-glass kettle body 1 includes a main body 101 and a constricted portion 102 formed on the bottom of the main body 101 and constricted in the radial direction; wherein, the fixing ring 6 is fitted around the outer periphery of the constricted portion 102 and forms a glue groove with the side wall of the constricted portion 102, the glue groove being filled with glue to connect and fix the fixing ring 6 to the all-glass kettle body 1. The second temperature probe 4 abuts against the outer side wall of the bottom of the main body 101 to achieve temperature detection.
[0059] Additionally, it includes a bottom cover 12 that covers the bottom of the all-glass kettle body 1 and encloses it to form an installation cavity. The heating module 2, control board 5, heat insulation cover 7, and fixing ring 6 are all disposed inside the bottom cover 12. Furthermore, it includes a sealing ring 10 disposed at the bottom of the main body 101 and located on the outer periphery of the constricted portion 102. The sealing ring 10 abuts against the bottom cover 12 and the fixing ring 6 to form a waterproof seal.
[0060] In this embodiment, a bottom bracket 13 is also provided inside the bottom cover 12 and located at the bottom of the heat insulation cover 7. The bottom cover 12 is installed at the bottom of the all-glass pot body 1 through the bottom bracket 13.
[0061] In addition, it also includes an upper coupler 11 disposed inside the bottom cover 12. The bottom cover 12 has a through hole that communicates with the upper coupler 11. The all-glass heating kettle is coupled to the lower coupler on the base through the upper coupler 11 to achieve electrical conduction.
