Description
Technical Field
[0001] The utility model relates to household appliances, in particular to a liquid heater. Background Art
[0002] In the process of cooking or boiling food in a liquid heating container, some non-liquid state water or other liquid substances will be generated during the cooking process. For example, in the process of making soy milk or boiling rice porridge, some soybeans or white rice are first added to the liquid, and heating devices such as heating tubes in the liquid heating container are used to heat the liquid-soybean mixture or liquid-rice mixture. During the cooking process, some slurry substances such as bubbles, foams, and pastes will be generated in the liquid-soybean mixture or liquid-rice mixture.
[0003] In the prior art, in order to prevent the slurry substances from rising to a relatively high height and overflowing from the liquid heating container, a detection plate for non-contact detection is generally provided on the liquid heating container. For example, a kettle disclosed in the prior art CN 215127293U includes: a kettle body, the bottom of which is provided with a heating assembly and a thermostat, and the kettle body is also provided with a temperature detector for detecting the temperature inside the kettle body and a water level detector for detecting the water level inside the kettle body; a circuit board is arranged at the bottom of the kettle body and is electrically connected to the heating assembly, the thermostat, the temperature detector, and the water level detector respectively. The thermostat can control the operation of the heating assembly according to the temperature detected by the temperature detector and the water level detected by the water level detector. The kettle provided by the above prior art can accurately and reliably control the heating operation of the heating assembly through the cooperation of the temperature detector and the water level detector, so as to prevent hot water with too high a temperature from overflowing the kettle, or prevent the kettle from dry burning to protect the kettle and improve the user experience. The water level detector is a capacitive detector, and the water level detector is arranged outside the kettle body. The specific installation method is that one side of the handle close to the kettle body has a connecting portion for connecting with the side wall of the kettle body. The connecting portion has a certain length to form a receiving cavity for installing the water level detector between the connecting portion and the side wall of the kettle body. The water level detector is installed in the receiving cavity. The bottom of the water level detector is bent towards the side of the kettle body and is electrically connected to the circuit board located in the installation cavity, with a reasonable and compact structure.
[0004] In the above prior art, the handle is generally made of an opaque material, and when the user operates, the handle will be held, and there are certain strength requirements for the handle, so the handle cannot be designed with a hollow structure. This results in the inability to observe the installation situation of the water level detector during the installation of the water level detector, and the inability to ensure the installation quality of the water level detector, which will affect the subsequent water level detection.

[0038] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0039] The utility model provides a liquid heater, such as Figures 1 to 4 As shown, it includes a glass cup body 100 and a shell 300, and the shell 300 is located on the outside of the glass cup body 100. A detection component 400 extending in the height direction is provided on the outside of the glass cup body 100, and the detection component 400 is hidden between the glass cup body 100 and the shell 300. The detection component 400 includes a mounting bracket 42 and a detection plate 41 for detecting the liquid level in the air. The mounting bracket 42 includes two first brackets 421 extending in the height direction and connected to each other. The two first brackets 421 are hollowed out to form a groove. One end of the first bracket 421 is a movable action end 4211, so that an elastic arm is formed on the first bracket 421, and an opening 420 is formed between the action ends 4211 of the two first brackets 421 for inserting the detection plate 41. The two action ends 4211 have a tendency to approach each other. The detection plate 41 is inserted into the groove from the opening 420 along the extension direction of the first bracket 421 and is clamped and fixed on both sides by the two first brackets 421. The detection plate 41 is close to the outer wall of the glass cup body 100.
[0040] In the present utility model, the detection plate 41 is pre-fixed by the mounting bracket 42, and the pre-fixing method of clamping the detection plate 41 by the elastic arm facilitates the insertion of the detection plate 41 into the groove, facilitates the assembly of the detection component 400, is conducive to the subsequent fixed connection between the detection component 400 and the glass cup body 100, and is conducive to improving the assembly efficiency. The mounting bracket 42 is designed as two first brackets 421 that extend in the height direction and are connected to each other. There is a hollow between the two first brackets 421 to form a groove. The structure is simple, and during the installation process, the installation situation of the detection plate 41 can be directly observed to ensure that the detection plate 41 obtains good installation quality, which is conducive to ensuring the liquid level detection function of the detection plate 41. Generally, electronic components will be arranged on the surface of the detection plate 41 facing away from the glass cup body 100. Only the two side edges of the detection plate 41 are clamped and fixed, which will not block the surface of the detection plate 41 facing away from the glass cup body 100, avoiding interference with the electronic components and not affecting the subsequent waterproof and dustproof encapsulation of the detection plate 41. The two first brackets 421 can also restrain the glue for encapsulating the detection plate 41, effectively preventing the glue from overflowing.
[0041] The glass cup body 100 can generally be a simple glass product, and the detection component is in direct contact with the glass material. The glass cup body 100 can also include a glass matrix and a film. The film is provided on the outer side of the glass matrix and can cover a part or the whole of the outer side of the glass matrix. Some marks, such as water level marks, prompt marks, etc., will be set on the film. At this time, the outer side wall of the glass cup body 100 is the outer side of the film, and the detection component is in contact with the film. In addition, a silk-screen shielding layer, such as ink or a film, can be provided on the outer side wall of the glass cup body 100, which can prevent users from directly observing the detection component through the glass cup body 100 from the inside of the glass cup body 100, improving the aesthetics. The silk-screen shielding layer is considered to be a part of the glass cup body 100, and the outer side wall of the glass cup body 100 is the outer side of the silk-screen shielding layer, and the detection component is in contact with the silk-screen shielding layer.
[0042] A heating plate is provided at the bottom of the glass cup body 100. The heating plate cooperates with the glass cup body 100 to form a container for holding liquid. A heating tube is provided on one side of the heating plate and is arranged around the center of the heating plate. When the heating tube works, it can heat the food in the container. The housing 300 can only shield a part of the outer side wall of the glass cup body 100, for example Figure 1The middle shell 300 is designed with a handle 31, which can cover the detection component 400, so that the user can observe the working conditions inside the container through the glass cup body 100, thereby improving the user experience. The shell 300 can also completely cover the outer wall of the glass cup body 100 to protect the glass cup body 100, and an observation window can be opened on the shell 300 to observe the working conditions inside the container. It is a prior art that the detection board 41 realizes the function of liquid level detection, which is generally realized by the sensing electrode sheet. For details, please refer to the signal PCB board mentioned in the prior art CN106108646A, which will not be repeated here.
[0043] In one embodiment, the end of the first bracket 421 away from the action end 4211 is a fixed end 4212, and the two fixed ends 4212 are connected by a second bracket 422. After the detection plate 41 is inserted into the groove, it rests against the second bracket 422 for positioning. The second bracket 422 serves to connect the two fixed ends 4212 and also serves to position the detection plate 41. The structure is simple and the functions are multiple. In addition, the end of the first bracket 421 away from the action end 4211 is a fixed end 4212, so that the length of the elastic arm is longer, the elastic effect is optimal, and it is more labor-saving when inserting the detection plate 41.
[0044] In order to make the detection board 41 as close to the outer wall of the glass body 100 as possible, a limiting rib 423 can be provided at the corner where the second bracket 422 is connected to the fixed end 4212, and the limiting rib 423 is against the side of the detection board 41 away from the glass body 100. The limiting rib 423 is located at the corner where the second bracket 422 is connected to the fixed end 4212, which can also increase the reliability of the connection between the second bracket 422 and the fixed end 4212.
[0045] In another embodiment, the limiting rib 423 may not be arranged at the corner where the second bracket 422 is connected to the fixed end 4212. For example, the limiting rib 423 is arranged on the second bracket 422, and the limiting rib 423 extends to the hollow area between the two first brackets 421. The limiting rib 423 is connected to the first bracket 421, which can shorten the elastic deformation length of the first bracket 421, and the effect of clamping the detection plate 41 will be more reliable. The structural strength of the mounting bracket 42 can also be increased. The limiting rib 423 is against the side of the detection plate 41 away from the glass cup body 100. The limiting rib 423 can apply pressure to make the detection plate 41 as close to the outer wall of the glass cup body 100 as possible. It can be understood that the limiting rib 423 may not be connected to the first bracket 421. Figure 5 As shown, the elasticity of the first bracket 421 is not affected. When the limiting rib 423 is arranged on the second bracket 422, it can be designed to be wider and shorter, so as to better limit the position of one end of the detection plate 41. Figure 6As shown, the length of the limiting rib 423 can also be extended longer, even to the vicinity of the action end 4211.
[0046] It can be understood that the limiting rib 423 can be provided at the corner where the second bracket 422 is connected to the fixed end 4212 and on the second bracket 422 at the same time.
[0047] In order to improve the pre-fixing effect of the detection plate 41, a positioning rib 424 for limiting the end of the detection plate 41 can be provided at the action end 4211 of the first bracket 421, and the positioning rib 424 abuts against the end of the detection plate 41 to prevent the detection plate 41 from slipping out of the groove in the opposite direction of the insertion direction. Since the detection plate 41 extends a certain length in the height direction, in order to make the detection plate 41 as a whole better close to the outer wall of the glass cup body 100, on the basis of setting the positioning rib 424, a limiting rib 423 can be provided at the corner where the positioning rib 424 is connected to the action end 4211, and the limiting rib 423 abuts against the side of the detection plate 41 away from the glass cup body 100. The limiting rib 423 is provided at the corner where the positioning rib 424 is connected to the action end 4211, and the reliability of the connection between the positioning rib 424 and the action end 4211 can also be increased.
[0048] To shorten the length of the elastic arm on the first bracket 421, Figure 7 and Figure 8 As shown, the middle parts of the two first brackets 421 are connected so that the middle part of the first bracket 421 forms a fixed end 4212, and the other end of the first bracket 421 can also become a movable action end 4211, and the detection plate 41 can be inserted into the groove at any end, which is conducive to improving assembly efficiency. Here, the middle parts of the two first brackets 421 can be connected not by the limiting rib 423, but by the connecting rib 425. The connecting rib 425 only serves to connect the two first brackets 421, and cannot be against the detection plate 41 to play the role of the limiting rib 423.
[0049] In addition to the above-mentioned arrangement, the limiting rib 423 may also be provided on the first bracket 421. Figure 9 As shown, the limiting rib 423 is against the side of the detection plate 41 away from the glass body 100, pressing the detection plate 41 to the outer wall of the glass body 100. In one embodiment, the limiting rib 423 can extend horizontally and connect the two first brackets 421, or can be as shown in FIG. Figure 10As shown, the limiting rib 423 extends from one of the first brackets 421 towards the hollow area between the two first brackets 421 and is not connected to the other first bracket 421. In addition, the limiting rib 423 can be connected to the middle section of the two first brackets 421, or on the basis that the other end of the first bracket 421 is the fixed end 4212 away from the action end 4211, the limiting rib 423 is connected to the two fixed ends 4212. The limiting rib 423 can also extend towards the action end 4211, as Figure 11 shown.
[0050] After the detection plate 41 is pre-fixed by the mounting bracket 42 to form an integral body, they are then fixed to the glass body 100 together. For example, in one embodiment, it can be selected that the detection plate 41 is fixed to the mounting bracket 42 by glue, and after the glue for fixing the detection plate 41 solidifies, the mounting bracket 42 and the detection plate 41 are adhesively fixed to the outer side wall of the glass body 100 together by glue. In addition to using glue for fixing, in other embodiments, other common methods can also be used to install and fix the mounting bracket.
[0051] In addition to the above preferred embodiments, the present utility model has other implementation manners. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope claimed by the present utility model.
