Description

Technical Field

[0001] The utility model relates to a kitchen appliance, in particular to a liquid heater which is easy to install. Background Art

[0002] Prior art CN201610753199.4 discloses that a signal PCB board is provided between the cup body and the hand-held handle of a food processor, and a metal sheet is provided on the signal PCB board. When the volume of the food in the cup body changes, the capacitor formed by the metal sheet and the food in the cup body will generate a charge signal, and the signal PCB board will then transmit the charge signal to the control circuit board. The control circuit board can judge the height of the current food liquid level in the cup body according to the transmitted signal. At the same time, the control circuit board controls the electric heating element or the knife group according to the current liquid level, thereby effectively controlling the change of the liquid level of the food and preventing food from overflowing. However, in this solution, there is an installation gap between the signal PCB board and the cup body, and the signal PCB board has no reliable positioning structure relative to the cup body, and the relative positions of the two are not fixed. Based on this, the signal PCB board cannot accurately identify the overflow signal. Therefore, the above-mentioned food processor still does not completely solve the problem of food overflow.

[0003] In order to make the detection plate and the cup body have a relatively better positioning relationship. The applicant previously proposed a patent with application number CN201720526032.4. The patent discloses that the capacitive sensing plate is positioned on the outer wall of the glass cup through a handle shell. During the installation process, two symmetrical and oppositely spliced ​​and fixed handle covers need to clamp the handle while clamping the capacitive sensing plate, so as to achieve the positioning of the capacitive sensing plate while fixing the handle shell, and ensure the relative position relationship between the capacitive sensing plate and the glass cup body. Although in this solution, the capacitive sensing plate and the glass cup body are in a relatively fixed relationship and no displacement will occur between the two, in this structure, a handle is required to be provided on the glass cup 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 complicated, but also when there is an assembly error between the handle shell and the handle, it will cause the capacitive sensing plate to detect the liquid level signal inaccurately. What's more, the existing food processing machines or health pots use a large amount of tubular glass, and tubular glass cannot be integrally formed into a handle structure on the glass cup body. Therefore, the above solution cannot be applied to tubular glass cup bodies.

[0004] In addition, the prior art CN201921962352.X also discloses a capacitive continuous liquid level detection structure and an electric kettle thereof. In this scheme, the outer surface of the kettle body of the electric kettle is an arc-shaped structure, so a soft PFB board is pasted on the outer wall of the kettle body. Although the soft PFB board can solve the problem of installing the liquid level detection board on the tube glass cup body, the soft PFB board has a higher manufacturing cost and is more prone to damage. Moreover, during the boiling process of the electric kettle, the high temperature of the outer wall of the kettle is likely to cause the denaturation of the viscose, which not only affects the adhesive effect of the detection board for long-term use, but also the denatured viscose may cause damage to the printed circuit on the detection board. Based on this, how to reliably position and install the rigid liquid level detection board on the outer wall of the arc-shaped glass cup body has always been a difficulty for R&D engineers who want to apply the remote detection technology to kitchen appliances to detect liquid levels.

The surrounding wall forms a accommodating cavity for accommodating the detection plate, the edge of the detection plate abuts against the inner wall of the surrounding edge, and the detection plate divides the accommodating cavity into an inner cavity located on one side of the glass cup body and an outer cavity located on one side of the positioning plate, wherein a recessed connecting groove is also provided on the inner wall of the surrounding edge, and the connecting groove connects the inner cavity with the outer cavity, and a glue inlet connected to the accommodating cavity is also provided on the outer wall of the positioning plate, and glue is poured into the accommodating cavity through the glue inlet, so that the glue is filled into the inner cavity and the outer cavity through the connecting groove to encapsulate the detection plate.

[0007] Furthermore, the surrounding edge includes a first side surrounding edge and a second side surrounding edge vertically arranged on both side edges of the positioning plate, and there are multiple connecting grooves, and the multiple connecting grooves are staggeredly distributed on the first side surrounding edge and the second side surrounding edge.

[0008] Furthermore, the surrounding edge is arranged around the edge of the positioning plate, and an opening is provided on one side of the surrounding edge, and the opening is communicated with the accommodating cavity.

[0009] Furthermore, after the positioning plate is positioned to the outer surface of the peripheral wall of the glass body, the detection plate is installed into the accommodating cavity through the opening;

[0010] Alternatively, the detection board includes a liquid level detection area with a capacitor electrode installed and a signal processing area with a processing chip installed, wherein after the detection board is installed in the accommodating cavity, the signal processing area is exposed to the positioning plate through the opening;

[0011] Alternatively, the opening is a glue inlet for pouring glue into the accommodating cavity.

[0012] Furthermore, the glue inlet is one or more hollow openings arranged on the positioning plate and connected to the outer chamber;

[0013] Alternatively, the surrounding edge is a closed annular surrounding edge arranged around the edge of the positioning plate.

[0014] Furthermore, the outer surface of the peripheral wall of the glass body is in the shape of a curved surface convex outward, the detection plate is located in the accommodating cavity and is pressed against the peripheral wall of the glass body, and the inner chamber is formed between the two side edges of the detection plate and the peripheral wall of the glass body;

[0015] Alternatively, the outer surface of the peripheral wall of the glass cup body is a curved surface concave toward the center of the glass cup body, the detection plate is located in the accommodating cavity and pressed against the peripheral wall of the glass cup body, the inner chamber is formed between the detection plate and the peripheral wall of the glass cup body, and the horizontal cross-section of the inner chamber is crescent-shaped.

[0016] Furthermore, the edge end surface is matched with the outer surface of the peripheral wall of the glass body, and the fitting width between the two is not less than 2 mm;

[0017] Alternatively, the cavity wall of the accommodating cavity is provided with a pressing portion for pressing the detection plate tightly against the glass body.

[0018] Furthermore, the top of the positioning plate has a hooking portion hooked on the edge of the glass body, and the positioning plate is pre-positioned on the glass body through the hooking portion;

[0024] Alternatively, after the glue filling process, the shielding member presses the positioning plate and is fixed to the outer side of the glass body.

[0025] Most of the existing liquid heaters use tubular glass to make the cup body. Due to the fragility of the tubular glass material, it is impossible to set screw positions, buckle positions and other structures on the glass surface to fix the detection plate. Of course, fiberglass, tempered glass, bulletproof glass and the like with higher strength and thickness can meet the above requirements, but this type of glass material greatly increases the manufacturing cost. Moreover, the thickness of the glass is relatively thick, which also significantly increases the weight of the cup body, making it inconvenient for consumers to use and unable to achieve mass application. Based on this, the prior art generally uses glue to bond the soft detection plate, or fixes the detection plate by positioning the handle. However, the manufacturing cost of the soft detection plate is high, and the soft detection plate is easy to be damaged, which greatly increases the subsequent maintenance cost. And the positioning by the handle is easy to form assembly tolerance, causing the detection plate to be offset relative to the glass cup body, and the detection accuracy will also be reduced. Moreover, a positioning structure for positioning the handle is also provided on the glass cup body, which increases the manufacturing difficulty.

[0026] As for the present application, the outer surface of the peripheral wall of the glass cup body is curved, and a positioning plate is fixed on the outer side of the peripheral wall of the glass cup body, and the positioning plate and the peripheral wall of the glass cup body enclose a receiving cavity for positioning and installing the detection plate, and a glue inlet connected to the receiving cavity is also provided on the outer wall of the positioning plate. After the detection plate is pre-positioned in the receiving cavity, the glue is poured into the receiving cavity through the glue inlet by a glue pouring process. After a period of standing, the detection plate can be firmly fixed on the outer wall of the glass cup body, which effectively solves the problem of fixing a rigid detection plate on the outer wall of a curved glass cup body in the prior art, and the positioning plate also has a good function of protecting the detection plate. At the same time, the edge of the positioning plate has a surrounding edge that fits tightly with the glass cup body. In the process of pouring glue into the receiving cavity, the glue is not easy to overflow from the gap between the positioning plate and the glass cup body, which ensures the effective use of the glue and solves the problem of difficult cleaning and glue waste after glue overflow. In addition, after the detection board is installed in the accommodating cavity, the edge of the detection board will abut against the side wall of the surrounding edge. In order to better allow the glue to fill every corner of the accommodating cavity, a recessed connecting groove will be provided on the inner side wall of the surrounding edge to connect the inner chamber and the outer chamber separated by the detection board. In this way, during the glue pouring process, the glue can be filled into the inner chamber and the outer chamber through the connecting groove to achieve the packaging of the entire detection board, which not only ensures the reliability of the positioning and fixation of the detection board, but also achieves the waterproof sealing of the detection board. Therefore, compared with the traditional glue pouring method of wrapping the entire detection board as a whole, the technical solution of the utility model is easier to install, and the amount of glue used is less, and it is not easy to have the problem of overflow glue waste. At the same time, it can also achieve the effect of better positioning and packaging the detection board. Moreover, the technical solution of the present application has lower manufacturing costs and higher production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment 1:

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The figure shows a partial structural diagram of a liquid heater of the utility model. The liquid heater is a health pot that can be used to brew beverages. It includes a glass cup body 1, the outer surface of the peripheral wall of the glass cup body 1 is a curved surface structure that bulges outward, and a positioning plate 2 is vertically installed on the outer side of the peripheral wall of the glass cup body 1, and the edge of the positioning plate 2 has a rim 21 that bulges toward the glass cup body 1. In this embodiment, the rim 21 is a closed annular rim arranged around the edge of the positioning plate 2, and the end face of the rim 21 is adapted to the outer surface of the peripheral wall of the glass cup body 1 and fits tightly, wherein adhesive is arranged on the end face of the rim 21, and the positioning plate 2 is fixed to the outer surface of the peripheral wall of the glass cup body 1 by the adhesive. The positioning plate 2 and the peripheral wall of the glass cup body 1 are combined to form a accommodating cavity 10 for accommodating and positioning the detection plate 3. The detection plate 3 is completely enclosed in the accommodating cavity 10. When installed, the edge of the detection plate 3 abuts against the inner wall of the surrounding edge 21, and the detection plate 3 divides the accommodating cavity 10 into an inner chamber 101 on the side of the detection plate 3 facing the glass cup body 1 and an outer chamber 102 on the side of the detection plate 3 facing the positioning plate 2, wherein a recessed connecting groove 200 is also provided on the inner wall of the surrounding edge 21 in the accommodating cavity 10, and the connecting groove 200 connects the inner chamber 101 with the outer chamber 102, and a glue inlet 20 connected to the accommodating cavity 10 is also provided on the outer wall of the positioning plate 2, and glue is poured into the accommodating cavity 10 through the glue inlet 20, so that the glue is filled into the inner chamber 101 and the outer chamber 102 through the connecting groove 200 to encapsulate the detection plate 3.

[0040] In this embodiment, since the peripheral wall of the glass body 1 is curved, and the detection board 3 is a rigid straight plate structure, after the detection board 3 is installed in the accommodating cavity 10, the detection board 3 is pressed against the glass body, and the inner chamber 101 is formed between the two side edges of the detection board 3 and the peripheral wall of the glass body 1. Glue is poured into the accommodating cavity 10 through the glue inlet 20, and after the inner chamber 101 and the outer chamber 102 are filled with glue and left to stand for a period of time, the detection board 3 will be located in the accommodating cavity 10 and fixed to the glass body 1 and the positioning plate 2 as a whole, and the detection board 3 is encapsulated by the solidified glue.

[0041] In the present embodiment, the end face of the rim 21 is in the shape of a curved surface that matches the outer surface of the peripheral wall of the glass cup body 1, so that when the positioning plate 2 is pasted to the outer surface of the peripheral wall of the glass cup body 1, a close fit relationship between the surfaces can be formed. Among them, in the present embodiment, the glue inlet 20 is arranged on the back of the positioning plate 2, and the glue inlet 20 is directly connected to the outer chamber 102. In the present embodiment, the rim 21 includes a first side rim 211 and a second side rim 212 vertically arranged on the edges of both sides of the positioning plate 2, and there are multiple connecting grooves 200, and the multiple connecting grooves 200 are staggered on the first side rim 211 and the second side rim 212. Due to the presence of multiple connecting grooves 200, the flow of the glue can be accelerated during the glue pouring process, so that the inner chamber 101 and the outer chamber 102 can be filled with glue more quickly.

[0042] Moreover, in the present embodiment, the detection board 3 is installed on the outer wall of the glass cup body 1 for detecting the height of the liquid level in the glass cup body 1 in the air, so that there is no need to set a separate liquid level electrode in the glass cup body 1 for detection, which is not only convenient for users to clean, but also avoids directly setting a mounting structure on the glass cup body 1 for installing the liquid level electrode, which can greatly reduce the scrap rate of the glass cup body 1, improve the yield rate, and reduce the production cost of the product. In the present embodiment, a plurality of capacitor electrodes 31 are provided on the side of the detection board 3 facing the glass cup body 1, and the capacitor electrodes 31 form a liquid level detection area. At the same time, a signal processing area is provided on the other side of the detection board 3 to install a processing chip (not shown in the figure). The processing chip processes the capacitance value generated by each capacitor electrode 31 to obtain a liquid level signal and realize accurate detection of the liquid level.

[0043] Most of the existing liquid heaters use tubular glass to make the cup body. Due to the fragility of the tubular glass material, it is impossible to set screw positions, buckle positions and other structures on the glass surface to fix the detection plate. Of course, fiberglass, tempered glass, bulletproof glass and the like with higher strength and thickness can meet the above requirements, but this type of glass material greatly increases the manufacturing cost. Moreover, the thickness of the glass is relatively thick, which also significantly increases the weight of the cup body, making it inconvenient for consumers to use and unable to achieve mass application. Based on this, the prior art generally uses glue to bond the soft detection plate, or fixes the detection plate by positioning the handle. However, the manufacturing cost of the soft detection plate is high, and the soft detection plate is easy to be damaged, which greatly increases the subsequent maintenance cost. And the positioning by the handle is easy to form assembly tolerance, causing the detection plate to be offset relative to the glass cup body, and the detection accuracy will also be reduced. Moreover, a positioning structure for positioning the handle is also provided on the glass cup body, which increases the manufacturing difficulty.

[0044] As for the present embodiment, the outer surface of the peripheral wall of the glass cup body is in the shape of a convex curved surface, and a positioning plate is fixed on the outer side of the peripheral wall of the glass cup body, and the positioning plate and the peripheral wall of the glass cup body enclose a receiving cavity for positioning and installing the detection plate, and a glue inlet connected to the receiving cavity is also provided on the outer wall of the positioning plate. After the detection plate is pre-positioned in the receiving cavity, the glue is poured into the receiving cavity through the glue inlet by a glue pouring process. After a period of standing, the detection plate can be firmly fixed on the outer wall of the glass cup body, which effectively solves the problem of fixing a rigid detection plate on the outer wall of a curved glass cup body in the prior art, and the positioning plate also has a good function of protecting the detection plate. At the same time, the edge of the positioning plate has a surrounding edge that fits tightly with the glass cup body. In the process of pouring glue into the receiving cavity, the glue is not easy to overflow from the gap between the positioning plate and the glass cup body, which ensures the effective use of the glue and solves the problem of difficult cleaning and glue waste after glue overflow. In addition, after the detection board is installed in the accommodating cavity, the edge of the detection board will abut against the side wall of the surrounding edge. In order to better allow the glue to fill every corner of the accommodating cavity, a recessed connecting groove will be provided on the inner side wall of the surrounding edge to connect the inner chamber and the outer chamber separated by the detection board. In this way, during the glue filling process, the glue can be filled into the inner chamber and the outer chamber through the connecting groove to achieve the packaging of the entire detection board, which not only ensures the reliability of the positioning and fixation of the detection board, but also achieves the waterproof sealing of the detection board. Therefore, compared with the traditional glue filling method of wrapping the entire detection board as a whole, the technical solution of this embodiment is easier to install, and the amount of glue used is less, and it is not easy to have the problem of glue overflow and waste. At the same time, it can also achieve the effect of better positioning and packaging the detection board. Moreover, the technical solution of this embodiment has lower manufacturing cost and higher production efficiency.

[0045] It should be noted that, in this embodiment, the positioning plate is fixed to the outer surface of the peripheral wall of the glass cup body by means of glue. Of course, the fitting installation method of the positioning plate and the glass cup body is not limited to gluing. The positioning plate can also be pressed against the outer wall of the glass cup body by means of press-fitting of other components. In addition, in this embodiment, the purpose of fitting the positioning plate to the glass cup body is to prevent the glue from overflowing from the gap between the positioning plate and the glass cup body during the glue filling process. The inventors have found through research that after the edge end face and the outer surface of the peripheral wall of the glass cup body are adapted, the fitting width D of the two should be no less than 2 mm (e.g. Figure 3 As shown), the end face of the surrounding edge and the glass cup body can form a face-to-face fitting relationship, wherein the fitting width D can also be understood as the fitting arc length of the cross section below and the surface. For this embodiment, the detection plate is first pre-positioned on the positioning plate by interference fit, and then the positioning plate is glued to the glass cup body, and finally the detection plate is encapsulated by a glue filling process to achieve the fixation and sealing of the detection plate. Of course, for this embodiment, an opening can also be set on one side of the surrounding edge (the lower end of the positioning plate), and the opening is connected to the accommodating cavity. The positioning plate can be first pasted on the glass cup body, and then the detection plate can be loaded into the accommodating cavity through the opening. After the detection plate is loaded into the accommodating cavity, the upper end of the detection plate is against the upper end wall of the accommodating cavity, and the detection plate is considered to be installed in place. At this time, the signal processing area on the detection plate will be exposed to the positioning plate through the opening, and finally the inner chamber and / or the outer chamber are filled with glue through the opening to achieve the encapsulation of the liquid level detection area on the detection plate. At this time, the opening is the glue inlet. Of course, the opening can also be set at the upper end of the positioning plate. For this embodiment, the wiring harness on the detection board can pass through the glue inlet and be electrically connected to the main controller, that is, the glue inlet is also the wiring port of the detection board. If the opening is the glue inlet, the wiring harness on the detection board can directly extend from the opening to be connected to the main controller. At this time, the opening is also the wiring port of the detection board.

[0046] At the same time, in this embodiment, the positioning plate is the positioning basis for the detection plate to be accurately positioned on the outer wall of the glass body. Therefore, during the installation process, it is necessary to ensure that the positioning plate can be accurately positioned on the glass body. In this embodiment, it is necessary to use tooling, for example, with the upper end of the glass mouth or the lower end of the glass body as the positioning reference, and then glue the positioning plate to the outer wall of the glass body.

[0047] It should also be noted that the detection board of this embodiment can detect both water level signals and overflow prevention signals, and a plurality of capacitor electrodes can be provided on the detection board for detecting different overflow prevention positions. Moreover, for this embodiment, the above structural changes can also be applied to other embodiments of the utility model.

[0048] Embodiment 2:

[0049] like Figure 7As shown, it is the second embodiment of the utility model. The difference between this embodiment and the first embodiment is that the outer surface of the peripheral wall of the glass cup body 1 is a curved surface concave toward the center of the glass cup body 1, the detection plate 3 is located in the accommodating cavity and pressed against the peripheral wall of the glass cup body 1, the inner chamber 101 is formed between the detection plate 3 and the peripheral wall of the glass cup body 1, and the horizontal cross-section of the inner chamber 101 is crescent-shaped.

[0050] At the same time, the positioning plate 2 is provided with a holding portion 22 for pressing the detection plate 3 against the glass body 1 on one side (i.e., the cavity wall of the accommodating cavity) of the detection plate 3, and an elastic member 4 is provided between the holding portion 22 and the detection plate 3, and the holding portion 22 presses the detection plate 3 against the glass body 1 through the elastic member 4. In this embodiment, the elastic member 4 is an elastic silicone pad or a rubber member.

[0051] In addition, in the present embodiment, the positioning plate 2 is a bracket structure with a hollow back, and the glue inlet 20 is one or more hollow openings on the positioning plate 2. When the detection plate 3 is installed, glue is poured into the outer chamber 102 through the glue inlet 20 (hollow opening), and the glue flows to the crescent-shaped inner chamber 101 through the connecting groove (not shown in the figure), and fills both the inner and outer chambers, and the detection plate 3 is packaged. After the glue pouring is completed, after standing for a period of time, the detection plate 3 can be fixed to the positioning plate 2 and the glass cup body 1, and the waterproof sealing of the detection plate 3 can also be achieved.

[0052] The positioning plate of this embodiment can be designed as a plate-like structure or a hollow bracket-like structure, and the shape of the positioning plate can be set according to the needs. At the same time, for this embodiment, it has the same beneficial effects as the first embodiment, which will not be repeated here. It should also be noted that the changes in the above structure of this embodiment can also be applied to other embodiments of the utility model.

[0053] Embodiment three:

[0054] like Figure 8 , Fig. 9 , Fig.10 The figure is a schematic diagram of the structure of the third embodiment of the utility model. The liquid heater of this embodiment is a food processing machine. For this embodiment, the detection plate 3 is also positioned on the outer wall of the glass body 1 through the positioning plate 2, wherein the top of the positioning plate 2 has a hook portion 24 hooked on the edge of the glass body 1, and the positioning plate 2 is pre-positioned on the glass body 1 through the hook portion 24. At the same time, the outer side of the positioning plate 2 is also provided with a shielding member covering the positioning plate 2. In this embodiment, the shielding member is a handle 5 that hides the positioning plate 2.

[0055] In this embodiment, the positioning plate is first positioned on the outer wall of the glass body through the hook portion, and then the detection plate is installed in the accommodating cavity enclosed by the positioning plate and the glass body. Finally, the accommodating cavity is filled with glue to encapsulate the detection plate. After the glue is filled, the handle is fixed to the outside of the glass body. Of course, after the glue filling process, the positioning plate can also be auxiliary pressed by the handle to prevent the positioning plate from falling off. For this embodiment, the detection plate has the dual protection of the positioning plate and the handle, which can prevent the detection plate from being damaged by external force.

[0056] It should be noted that, for this embodiment, the shielding member is not limited to the handle disclosed in this embodiment, and the shielding member may also be a shell fixed to the outer wall of the glass cup body, the shell hiding the positioning plate, and the shell may also be an operation panel for controlling the food processor. Alternatively, the shielding member may also be a cup body shell mounted on the outer side of the glass cup body, so that the food processor has a double-layer cup structure.

[0057] In addition, for this embodiment, the positioning plate is fixed to the outside of the glass cup body by hooking for pre-positioning. The pre-positioning structure of the positioning plate is not limited to hooking. For example, a cup seat is fixed at the bottom of the glass cup body, and the lower end of the positioning plate can also be pre-positioned on the cup seat to achieve pre-positioning of the positioning plate and the glass cup body before installing the detection plate.

[0058] Similarly, this embodiment has the same beneficial effects as the above embodiments, and this embodiment will not be described in detail. It should be noted that the above structural changes of this embodiment can also be applied to other embodiments of the utility model.

[0059] In addition, it should be noted that the liquid heater of the utility model is not limited to the food processor with integrated motor and cup body disclosed in the embodiment of the utility model, but can also be a soymilk machine with motor mounted on top, a wall-breaking machine with cup body and machine base separated, and a food processor that can realize automatic pulp discharge and automatic cleaning without hand washing.
