Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a liquid heater. Background Art

[0002] The anti-overflow detection methods currently used in kitchen appliances include contact and non-contact types. For example, the Chinese patent application number 201720526032.4 previously filed by the present applicant discloses a non-contact anti-overflow detection method, in which a detection component is fitted on the outer wall of a glass, and the handle shell is used to position and shield the detection component at a preset position adjacent to the outer wall of the glass. Although in this solution, the capacitive sensing plate and the glass body are in a relatively fixed relationship and no displacement occurs between the two, and the fixed structure is reliable, in this structure, a handle is required on the glass body to position the handle shell, and then the capacitive sensing plate is fixed and limited by the positioning of the handle shell. Not only is the installation structure complex and the installation steps cumbersome, but the assembly errors between the various parts accumulate, resulting in inaccurate assembly position of the sensing plate and inaccurate detection.

[0003] The applicant has previously filed an application with application number CN2024103319154, in which the detection plate is positioned on the outer wall of the glass cup body with the help of a positioning plate, and a receiving cavity for accommodating the detection plate is formed by the positioning plate and the peripheral wall of the glass cup body. The detection plate is first positioned in the receiving cavity, and then glue is poured into the receiving cavity. After the glue solidifies, the detection plate is reliably positioned in the receiving cavity, which simplifies the positioning structure of the detection plate, facilitates installation, and reduces assembly errors. However, if the detection plate is bonded to the outer wall of the glass cup body by simply using glue, since the glass cup body will be heated when it is in working condition, the glue layer will soften due to long-term heat, the viscosity will deteriorate, and the fixing effect will not last long, which will cause the adhesion between the detection plate and the glass cup body to deteriorate, and the detection plate will separate from the glass cup body. Utility Model Content

[0004] The utility model provides a liquid heater, which positions the detection plate on the glass cup body by designing an installation structure, thereby solving the problem of complicated installation steps of the detection plate and the problem of poor durability of the fixing effect between the detection plate and the glass cup body in a long-term heating environment.

[0005] The technical solution adopted by the present invention is as follows: the present invention provides a liquid heater, comprising a glass body and a detection plate for detecting the liquid level in the air, the detection plate being strip-shaped and vertically arranged on the outside of the glass body, the liquid heater also comprising a mounting bracket fixed to the outer side surface of the glass body, the mounting bracket comprising a first surrounding edge and a second surrounding edge, the first surrounding edge and the second surrounding edge being respectively located on opposite sides of the detection plate, the first surrounding edge being provided with a protrusion, a slot being formed between the protrusion and the outer side surface of the glass body, the second surrounding edge being provided with an elastic member, one side of the detection plate being inserted into the slot, and the other side of the detection plate being limited by the elastic member, so that the detection plate is positioned on the outside of the glass body.

[0006] The liquid heater provided by the present invention is provided with a mounting bracket, which includes a first edge and a second edge. The first edge and the second edge are respectively located on opposite sides of the detection plate, defining the mounting position of the detection plate, facilitating the detection plate to be accurately installed in a preset position. A protrusion is provided on the first edge, and a slot is formed between the protrusion and the outer side of the glass body. An elastic member is provided on the second edge. By utilizing the elastic deformation characteristics of the elastic member, it is only necessary to first engage one edge of the detection plate in the slot, and then gently press the other edge of the detection plate. After the edge of the detection plate and the elastic member are squeezed and fitted, the elastic member and the slot are finally restrained together, so that the detection plate cannot be separated from the glass and is reliably positioned outside the glass body. Therefore, compared with the traditional technology that requires the detection plate to be positioned by multiple assembly parts such as the handle and the handle shell, the installation steps of the detection plate are greatly simplified, the operation is more convenient, time-saving and labor-saving, and assembly efficiency is improved. At the same time, it can also reduce the accumulation of assembly errors and improve detection accuracy. In addition, the detection plate is positioned by the slot and the elastic member on the opposite sides respectively, and the force on the detection plate is balanced, avoiding unilateral warping. The protrusions and elastic parts are used to prevent the detection plate from detaching from the glass cup body, thereby achieving mechanical fixation between the detection plate and the glass cup body, reducing the impact of the glass cup body being in a heated environment for a long time on the fixation reliability of the detection plate, making the fixation of the detection plate reliable and durable, and effectively preventing the detection plate from falling off or loosening.

[0007] In a preferred embodiment, the elastic member includes a connecting portion and a deformation portion connected to the second surrounding edge, the free end of the deformation portion forms a snap fit with the outer side surface of the glass cup body, the detection plate squeezes the deformation portion to fit into the snap fit, and the free end of the deformation portion abuts against the outer side surface of the detection plate after resetting.

[0008] The elastic part includes a connecting part and a deformation part. The free end of the deformation part is used to form a snap-in with the outer side surface of the glass cup body for the detection plate to be installed. After the detection plate squeezes the deformation part, the deformation part elastically moves to fit into the snap-in. In the process of the detection plate squeezing the deformation part, the deformation part also guides the detection plate, so that the detection plate is accurately installed to the preset position along the deformation part. The position of the detection plate is accurately installed, and the free end of the deformation part abuts against the outer side surface of the detection plate after resetting. The free end of the deformation part is used to directly prevent the detection plate from detaching from the glass cup body, so that the connection between the detection plate and the glass cup body is reliable.

[0009] In a preferred embodiment, the detection plate is clamped and limited by the slot and the elastic member.

[0010] The detection plate is clamped by the card slot and the elastic part, which can facilitate the assembly of the detection plate. The worker only needs to press the detection plate to the preset position to complete the positioning of the detection plate, which saves effort and is also convenient for the disassembly and assembly of the detection plate and the replacement of the detection plate. In addition, the detection plate can be positioned horizontally under the clamping force provided by the elastic part to prevent the detection plate from being offset, and can also be positioned vertically to prevent the detection plate from falling downward, so that the detection plate can be reliably fixed on the outside of the glass cup body.

[0011] More preferably, the elastic member is one of a silicone member, a spring, a spring sheet, and a snap button.

[0012] The elastic member is a silicone rubber component, which provides a certain cushioning effect. After one side of the test board engages with the slot, pressing down on the other side reduces the pressure, allowing the test board to be installed in place. At the same time, after the test board is pressed into place, the silicone component provides a flexible cushioning effect, preventing the test board from cracking or falling due to excessive clamping force, as well as damage to the elastic member. The elastic member uses a spring and shrapnel to facilitate a removable connection between the elastic member and the second edge of the mounting bracket, allowing for flexible assembly and disassembly. The number of elastic members can be flexibly and rationally arranged according to the size of the test board. For small test boards, the number of spring clips can be reduced to avoid unnecessary waste, while for large test boards, the number of spring clips can be increased, thus achieving reliable fixation for different test board sizes.

[0013] The elastic member is a spring buckle and can be integrally formed with the mounting bracket, thereby simplifying the processing technology.

[0014] Of course, no matter the elastic member is a silicone member, a spring, a shrapnel or a spring buckle, it can be flexibly deformed elastically, so that the detection plate is convenient to install and the detection plate is reliably limited.

[0015] In a preferred embodiment, the mounting bracket and the glass cup body are combined to form a positioning groove for accommodating the detection board. After the detection board is positioned in the positioning groove, glue is poured into the positioning groove to form a glue layer to encapsulate the detection board.

[0016] In a preferred embodiment, the mounting bracket and the glass cup body are combined to form a positioning groove for accommodating the detection board. A first glue potting layer is provided in the positioning groove and is formed by glue potting before the detection board is installed in the positioning groove. The detection board is adhered to the surface of the first glue potting layer. A second glue potting layer is also provided in the positioning groove and is formed on the outer surface of the detection board by glue potting after the detection board is installed in the positioning groove.

[0017] Whether the glue is poured before or after the detection plate is installed, forming a glue layer in the positioning groove can achieve secondary positioning of the detection plate, improve the reliability of positioning between the detection plate and the glass cup body, and is easy to operate.

[0018] In addition, by setting the first glue potting layer and the second glue potting layer, there is no interference from the detection board during the formation of the first glue potting layer, and the glue flows quickly, avoiding the situation where the glue has not yet circulated into place and solidification, so that the glue can fully fill the gap between the detection plate and the glass cup body, and the detection plate is attached to the surface of the first glue potting layer, making the first glue potting layer tight, further avoiding the formation of gaps between the detection plate and the glass cup body. On the one hand, it avoids condensation water entering the gap and affecting the accuracy of the detection. On the other hand, it can make the detection plate stable after positioning and achieve reliable positioning. Therefore, the first glue potting layer formed before the detection plate is installed can effectively improve the detection accuracy of the detection plate, and further improve the positioning stability and reliability of the detection plate, and use the second glue potting layer to achieve reliable sealing of the detection plate.

[0019] In a preferred embodiment, the detection plate has a long side extending vertically and a short side extending horizontally, the first surrounding edge and the second surrounding edge are respectively located on both sides of the long side of the detection plate, and the outer side of the glass cup body is also provided with a first rib and a second rib for stopping on both sides of the short side.

[0020] Since the first surrounding edge and the second surrounding edge are respectively located on both sides of the long side of the detection plate, the left and right limit of the detection plate is realized to avoid detection deviation, and the cooperation of the elastic member and the card slot is used to prevent the detection plate from falling off to the outside of the glass cup body. By setting the first guard edge and the second guard edge, the upper and lower limit of the detection plate can be achieved to prevent the detection plate from falling down or moving upward, and reliable positioning of the detection plate in multiple directions can be achieved, so that the installation position of the detection plate is more accurate and the detection is more accurate.

[0021] In a preferred embodiment, the first rib and the second rib are integrally protruded from the outer side of the glass body;

[0022] Alternatively, the first rib and the second rib are integrally formed on the mounting bracket, and the first surrounding edge and the second surrounding edge are connected to form a ring shape through the first rib and the second rib.

[0023] Regardless of whether the first rib and the second rib are located on the glass cup body or the mounting bracket, they can achieve multi-directional positioning of the detection plate after cooperating with the first surrounding edge and the second surrounding edge. When the first rib and the second rib are integrally formed on the mounting bracket, the processing and manufacturing of the glass cup body are simplified, and the production cost of the entire machine is reduced.

[0024] In a preferred embodiment, the detection plate has a long side extending vertically and a short side extending horizontally, and the first surrounding edge and the second surrounding edge are separately arranged on both sides of the short side of the detection plate.

[0025] In a preferred embodiment, the mounting bracket includes a decorative ring that is sleeved and fixed to the outside of the glass body, and the first surrounding edge is provided on the decorative ring;

[0026] Alternatively, the mounting bracket includes a cup seat that is sleeved and fixed to the outside of the glass body, and the second surrounding edge is arranged on the cup seat.

[0027] By separately arranging the first surround and the second surround on both sides of the short side of the detection plate, the shape design of the first surround and the second surround can be more flexible. In addition, since in some liquid heaters, some components are naturally set on the outside of the glass cup body due to functional requirements, such as a decorative ring that is sleeved on the outside of the glass cup body or a cup seat fixed on the lower side of the glass cup body, the first surround and the second surround are separately arranged on the decorative ring and the cup seat to achieve structural integration and simplification, making the structure of the whole machine compact.

[0043] like Figure 1-5 As shown, the present invention provides a liquid heater in one embodiment, including a glass body 10 and a detection plate 20 for detecting the liquid level in the air. The detection plate 20 is strip-shaped and vertically arranged on the outside of the glass body 10. The liquid heater also includes a mounting bracket 30 fixed to the outer side of the glass body 10. The mounting bracket 30 includes a first surrounding edge 31 and a second surrounding edge 32. The first surrounding edge 31 and the second surrounding edge 32 are respectively located on opposite sides of the detection plate 20. Figure 2 、 3 As shown, the first surrounding edge 31 is provided with a protrusion 60, and a groove 61 is formed between the protrusion 60 and the outer side surface of the glass cup body 10. The second surrounding edge 32 is provided with an elastic member 40. One side of the detection plate 20 is inserted into the groove 61, and the other side of the detection plate 20 is limited by the elastic member 40, so that the detection plate 20 is positioned on the outside of the glass cup body 10.

[0044] The liquid heater provided by the present invention is provided with a mounting bracket 30, and the mounting bracket 30 includes a first edge 31 and a second edge 32. The first edge 31 and the second edge 32 are respectively located on opposite sides of the detection plate 20, defining the installation position of the detection plate 20, which is conducive to the detection plate 20 being accurately installed at a preset position. A protrusion 60 is provided on the first edge 31, and a groove 61 is formed between the protrusion 60 and the outer side surface of the glass cup body 10. An elastic member 40 is provided on the second edge 32. By utilizing the elastic deformation characteristics of the elastic member 40, it is only necessary to first clamp one side edge of the detection plate 20 in the groove 61, and gently press the other side edge of the detection plate 20. After the edge of the detection plate 20 is squeezed and matched with the elastic member 40, it is finally limited by the elastic member 40 and the groove 61, so that the detection plate 20 cannot be separated from the glass cup and is reliably positioned to the outside of the glass cup body 10. Therefore, compared with the traditional technology in which the detection plate 20 needs to be positioned by multiple assembly parts such as the handle and the handle shell, the installation steps of the detection plate 20 are greatly simplified, the operation is more convenient, time-saving and labor-saving, and the assembly efficiency is improved. At the same time, the accumulation of assembly errors can be reduced, and the detection accuracy can be improved. In addition, the two opposite sides of the detection plate 20 are positioned by means of the card slot 61 and the elastic member 40 respectively, and the force on the detection plate 20 is balanced to avoid unilateral warping. Moreover, the protrusion 60 and the elastic member 40 are used to prevent the detection plate 20 from being outwardly separated from the glass cup body 10, thereby realizing the mechanical fixation between the detection plate 20 and the glass cup body 10, reducing the influence of the glass cup body 10 needing to be in a heated environment for a long time on the fixation reliability of the detection plate 20, making the fixation of the detection plate 20 reliable and durable, and effectively preventing the detection plate 20 from falling off or loosening.

[0045] It should be noted that the present invention does not limit the specific positioning method of the mounting bracket 30 on the detection plate 20. For example, any of the following implementation examples may be adopted:

[0046] Implementation Example 1, such as Figure 1-5 As shown, the elastic member 40 includes a connecting portion 41 connected to the second surrounding edge 32 and a deforming portion 42. Figure 3 As shown, the free end of the deformation portion 42 forms a bayonet 43 with the outer side of the glass body 10, as shown in FIG. Figure 4 As shown, the detection plate 20 is pressed downward to squeeze the deformed portion 42 to engage with the bayonet 43, as shown in FIG. Figure 5 As shown, the free end of the deformable portion 42 abuts against the outer side surface of the detection plate 20 after being reset.

[0047] The elastic member 40 includes a connecting portion 41 and a deforming portion 42. The free end of the deforming portion 42 and the outer side surface of the glass cup body 10 form a snap-in 43 for the detection plate 20 to be installed. After the detection plate 20 squeezes the deforming portion 42, the deforming portion 42 elastically moves to be installed into the snap-in 43. In the process of the detection plate 20 squeezing the deforming portion 42, the deforming portion 42 also guides the detection plate 20, so that the detection plate 20 is accurately installed to the preset position along the deforming portion 42. The position of the detection plate 20 is accurately installed, and the free end of the deforming portion 42 abuts against the outer side surface of the detection plate 20 after resetting. The free end of the deforming portion 42 is used to directly prevent the detection plate 20 from detaching from the glass cup body 10 outward, so that the connection between the detection plate 20 and the glass cup body 10 is reliable.

[0048] More specifically, if Figure 2 As shown, the elastic members 40 and the protrusions 60 are symmetrically arranged one by one, and multiple pairs are provided. Of course, the elastic members 40 and the protrusions 60 can also be arranged in a staggered manner.

[0049] Of course, it should be noted that the free end of the above-mentioned deformation part 42 abuts against the outer side surface of the detection plate 20, which can be selected as contact or pressure. Preferably, in this embodiment, the free end of the deformation part 42 provides a pressing force to press the detection plate 20, so that the detection plate 20 and the glass cup body 10 can be tightly attached, thereby improving the detection sensitivity of the detection plate 20.

[0050] In addition, it should be noted that, in order to achieve reliable positioning of the detection board 20 in multiple directions, in a preferred embodiment, as shown in FIG. Figure 2 As shown, the detection plate 20 has a long side extending vertically and a short side extending horizontally. The first surrounding edge 31 and the second surrounding edge 32 are respectively located on both sides of the long side of the detection plate 20. The outer side of the glass body 10 is also provided with two retaining edges 50 on both sides of the short side, namely the first retaining edge and the second retaining edge. Figure 2 As shown, the first rib and the second rib are integrally formed on the mounting bracket 30 , and the first surrounding edge 31 and the second surrounding edge 32 are connected to form a ring shape through the first rib and the second rib.

[0051] Since the first surrounding edge 31 and the second surrounding edge 32 are respectively located on both sides of the long side of the detection plate 20, the left and right limit of the detection plate 20 is realized to avoid detection deviation, and the cooperation of the elastic member 40 and the card slot 61 is used to prevent the detection plate 20 from falling off to the outside of the glass cup body 10. By setting the first retaining edge 50 and the second retaining edge 50, the upper and lower limit of the detection plate 20 can be achieved to prevent the detection plate 20 from falling down or moving upward, and the reliable positioning of the detection plate 20 in multiple directions is realized, so that the installation position of the detection plate 20 is more accurate and the detection is more accurate.

[0052] Of course, in practice, the first rib and the second rib can also be integrally protruded from the outer side surface of the glass cup body 10 .

[0053] Regardless of whether the first and second ribs are located on the glass body 10 or the mounting bracket 30, they cooperate with the first and second surrounding edges 31 and 32 to limit the position of the detection plate 20 in multiple directions. When the first and second ribs are integrally formed with the mounting bracket 30, the processing and manufacturing of the glass body 10 are simplified, reducing the production cost of the entire device. Of course, the embodiment of providing the first and second ribs is also applicable to other embodiments.

[0054] Implementation Example 2, such as Figure 6 As shown, the detection plate 20 is clamped and limited by the slot 61 and the elastic member 40. Preferably, the elastic member is a snap, including a connecting portion 41 connected to the second surrounding edge 32 and a deformable portion 42, the deformable portion 42 extending toward the glass body 10, and the detection plate 20 is clamped by the deformable portion 42 and the slot.

[0055] In fact, in this embodiment, the elastic member 40 can also be a silicone member, a spring, or a spring.

[0056] The detection plate 20 is clamped by the card slot 61 and the elastic member 40, which can facilitate the assembly of the detection plate 20. The worker only needs to press the detection plate 20 to the preset position to complete the positioning of the detection plate 20, which saves effort and is also convenient for the disassembly and assembly of the detection plate 20 and the replacement of the detection plate 20. In addition, the detection plate 20 can be positioned horizontally under the clamping force provided by the elastic member 40 to prevent the detection plate 20 from being offset, and can also be positioned vertically to prevent the detection plate 20 from falling downward, so that the detection plate 20 can be reliably fixed on the outside of the glass cup body 10.

[0057] The elastic member 40 is a silicone member that plays a certain cushioning role. After one side of the detection plate 20 is engaged with the card slot 61, the process of pressing the other side downwards saves more effort, allowing the detection plate 20 to be installed in place. At the same time, after the detection plate 20 is pressed into place, the silicone member flexibly cushions, preventing the detection plate 20 from cracking or falling due to a large clamping force, and preventing the elastic member 40 from being damaged. The elastic member 40 uses a spring and a spring clip to facilitate the detachable connection between the elastic member 40 and the second surrounding edge 32 of the mounting bracket 30. The assembly and disassembly are flexible, and the number of elastic members 40 can be flexibly and reasonably arranged according to the size of the detection plate 20. For small detection plates 20, the number of spring clips can be reduced to avoid unnecessary waste. For large detection plates 20, the number of spring clips can be increased, thereby achieving reliable fixation of different types of detection plates 20.

[0058] The elastic member 40 is a spring buckle and can be integrally formed with the mounting bracket 30 , thereby simplifying the manufacturing process.

[0059] Of course, no matter the elastic member 40 is a silicone member, a spring, a spring sheet or a spring buckle, it can be flexibly deformed elastically, so that the detection plate 20 can be easily installed and the detection plate 20 can be reliably limited.

[0060] Implementation Example 3, such as Figure 7 As shown, the mounting bracket 30 and the glass cup body 10 are enclosed to form a positioning groove for accommodating the detection board 20. A first glue potting layer 70 is provided in the positioning groove and is formed by glue potting before the detection board 20 is installed in the positioning groove. The detection board 20 is attached to the surface of the first glue potting layer 70. A second glue potting layer 71 is also provided in the positioning groove and is formed on the outer surface of the detection board 20 by glue potting after the detection board 20 is installed in the positioning groove.

[0061] It is understandable that this embodiment can be combined with other embodiments to perform a secondary positioning of the detection plate 20 based on the primary positioning of the elastic member and the slot.

[0062] Of course, the glue pouring method is not limited to the above one. In another embodiment, the mounting bracket 30 and the glass cup body 10 are enclosed to form a positioning groove for accommodating the detection board 20. After the detection board 20 is positioned in the positioning groove, glue is poured into the positioning groove to form a glue pouring layer to encapsulate the detection board 20.

[0063] Whether the glue is poured before or after the detection plate 20 is installed, forming a glue layer in the positioning groove can achieve secondary positioning of the detection plate 20, improve the reliability of positioning between the detection plate 20 and the glass cup body 10, and is convenient to operate.

[0064] By setting the first glue potting layer and the second glue potting layer, there is no interference from the detection board 20 during the formation of the first glue potting layer, and the glue flows quickly, avoiding the situation where the glue has not yet circulated into place and solidification, so that the glue can fully fill the gap between the detection board 20 and the glass cup body 10, and the detection board 20 is attached to the surface of the first glue potting layer, so that the first glue potting layer is tight, further avoiding the formation of gaps between the detection board 20 and the glass cup body 10. On the one hand, it avoids condensation water entering the gap and affecting the accuracy of the detection. On the other hand, it can make the detection board 20 stable after positioning and achieve reliable positioning. Therefore, the first glue potting layer formed before the detection board 20 is installed can effectively improve the detection accuracy of the detection board 20, and further improve the positioning stability and reliability of the detection board 20, and use the second glue potting layer to achieve reliable sealing of the detection board 20.

[0065] It should be noted that the positions of the first surrounding edge 31 and the second surrounding edge 32 are not limited to the one shown in the above embodiment 1. In another embodiment, for example:

[0066] Implementation Example 4, such as Figure 8 As shown, the detection board 20 has a long side extending vertically and a short side extending horizontally, and the first surrounding edge 31 and the second surrounding edge 32 are separately arranged on both sides of the short side of the detection board 20.

[0067] More preferably, the mounting bracket 30 includes a decorative ring that is sleeved and fixed on the outside of the glass cup body 10, and the first edge 31 is set on the decorative ring; the mounting bracket 30 includes a cup base that is sleeved and fixed on the outside of the glass cup body 10, and the second edge 32 is set on the cup base.

[0068] By separately arranging the first surround 31 and the second surround 32 on both sides of the short side of the detection plate 20, the shape design of the first surround 31 and the second surround 32 can be more flexible.
