Description

Technical Field

[0001] The utility model relates to the technical field of liquid heaters, in particular to a liquid heater. Background Art

[0002] Liquid heaters are typically designed as household appliances for boiling water, brewing tea, or making other beverages. To ensure safety and provide convenient functionality, liquid heaters need to sense and detect the state of the beverage, or inform the user of the status of the beverage. Therefore, the body and lid of the liquid heater can include multiple sensors to detect the beverage's status. Furthermore, displays and operating elements can be incorporated into the lid and handle to facilitate user monitoring and control of the liquid heater.

[0003] For example, in prior art CN202222200376.X, a water level sensor is installed on the side wall of the kettle. Specifically, a through hole is provided in the side wall of the kettle, and the sensor is passed through the through hole of the kettle body to detect the water level. A handle is also used to shield the sensor circuit, improving the aesthetics of the liquid heater.

[0004] For example, in the prior art CN201721213276.3, an overflow sensor is installed on the side wall of the kettle body. This solution sets an overflow sensor on the side wall of the kettle body, and the overflow sensor passes through, forming a lead channel between the outer wall of the kettle body and the handle, and finally connects to the controller.

[0005] For example, in the prior art CN202280053660.9, a display screen and control buttons are provided on the kettle body or lid. The wires associated with the display panel of the prior art can be connected from the lower shell to the handle section and finally connected to the display panel.

[0006] In summary, when installing devices such as sensors on the kettle body or kettle lid in the prior art, the conductive parts and cables of the devices need to be connected to the lower shell of the kettle body through a handle (partially called a handle).

[0007] However, for liquid heaters with a transparent body, the cable enters the lower shell through the handle, and some of the conductive parts are inevitably visible to the user through the transparent body, affecting the appearance. Therefore, the existing technology uses a shielding member between the conductive part and the body to prevent the user from seeing the conductive part.

[0008] For example, in prior art CN201821767103.0, the leads of the overflow prevention electrode pass through the handle and connect to the upper connector. Furthermore, an insulating shield and support pad are positioned between the kettle body and the handle to shield the overflow prevention and the leads. As in prior art CN201821800494.1, the components of the overflow prevention sheet and the conductive element are located between the silicone handle and the handle, thereby preventing the user from seeing the conductive element.

[0009] Furthermore, there's often space between the bottom edge of the kettle body and the heating element for mounting the lower shell. For a visible kettle body, users can see the internal structure through the visible portion between the heating element and the kettle body edge, affecting the aesthetics of the liquid heater. Therefore, prior art CN201821800494.1 also includes a gasket where the glass kettle body and metal shell fit together. This gasket not only obscures the visible portion of the kettle body's bottom, but also serves to secure the shell.

[0010] In summary, in liquid heaters with partially transparent bodies, shielding members are often required on the sidewalls of the body to shield the conductive members, while washers are also required on the bottom of the body to shield the visible area at the bottom. Therefore, these two components must be installed separately to ensure the aesthetics of the liquid heater. However, installing two shielding structures separately results in each shielding structure being independent and located on different sides of the body. Each shielding structure also requires coordination with different components, making installation and positioning more complex and affecting assembly efficiency. Utility Model Content

[0018] Furthermore, the inner diameter of the annular ring is smaller than the outer diameter of the heating component.

[0019] Furthermore, the installation bin is provided with a supporting structure, and the supporting structure abuts against the lower end surface of the annular ring.

[0020] Furthermore, the annular ring forms a support protrusion with a first notch downward along the outer edge, the first notch is located on the lower side of the shielding piece, the support protrusion abuts against the lower shell, and the conductive part passes through the first notch into the installation compartment.

[0021] Furthermore, the upper edge of the side wall of the lower shell is recessed downward to form an accommodating opening, the annular ring is provided with two second notches at the accommodating opening, and the side wall of the lower shell is located in the second notches on both sides of the shielding member.

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The liquid heater of this embodiment only needs to install one shielding member to simultaneously shield the wiring channel 201 of the handle 2 and the visible area of ​​the bottom surface of the kettle body 3, which ensures both the beauty of the liquid heater and the assembly efficiency.

[0040] like Figure 1As shown, the shielding member of this embodiment includes an integrally formed annular ring 102 and an upwardly folded baffle 101. The annular ring 102 is located in the installation compartment 400 and is used to cover the visible area between the heating component 5 and the bottom edge of the kettle body; the baffle 101 is located between the handle 2 and the kettle body to shield the conductive member 6. During installation, the annular ring 102 and the lower shell 4, and the baffle 101 and the handle 2 cooperate with each other, thereby facilitating the installation and positioning of the shielding member. This eliminates the need to install two separate shielding components as in the prior art, ensuring assembly efficiency.

[0041] First, the position and coordination of the baffle 101 depend on the layout of the conductive element 6. The wiring channel 201 for the conductive element 6 is located within the handle 2. The handle 2 includes a connection surface 210 adjacent to the kettle body 3 and a grip portion 220 for the user to grasp. Depending on the location of the wiring channel 201, the wiring channel 201 can be broadly categorized into two types. The first type is an internal wiring method, where the wiring channel 201 is located within the grip portion 220, leaving the conductive element 6 partially exposed. The second type is an external wiring method, where the wiring channel 201 is located on the connection surface 210, leaving the conductive element 6 completely exposed.

[0042] For the first form, such as Figure 2 As shown, the grip portion 220 of the handle 2 is provided with a wiring channel 201, the outlet of which is higher than the lower housing 4. The conductive member 6 extends from the outlet of the wiring channel 201, passes between the handle 2 and the kettle body, and then enters the installation compartment 400. The conductive member 6 is exposed when passing between the handle 2 and the kettle body, affecting the aesthetics of the liquid heater. Therefore, the shielding piece 101 is higher than the outlet of the wiring channel 201, thereby shielding the conductive member 6.

[0043] like Figure 3 As shown, after the conductive part 6 extends out from the wiring channel 201, the conductive part 6 enters the installation compartment 400 through the gap between the handle 2 and the kettle body, and the conductive part 6 protrudes from the connection surface 210 where the handle 2 and the kettle body 3 are connected. The user can see the conductive part 6 from the front. Therefore, the baffle 101 is located between the above-mentioned handle 2 and the kettle body to shield the above-mentioned conductive part 6. The above-mentioned baffle 101 can abut against the outer wall of the kettle body to prevent water vapor from entering between the baffle 101 and the kettle body. At this time, the shielding member can be positioned by the annular ring 102. Furthermore, an elastic member 1012 can be provided in the gaps on both sides of the conductive part 6. The elastic member 1012 can not only seal the gaps on both sides of the conductive part 6; during the user's grip, the elastic member 1012 prevents the baffle 101 and the handle 2 from crushing the conductive part 6. In order to further reduce the parts that need to be assembled, it is also possible to Figure 4As shown, the baffle 101 is provided with flanges 1011 on both sides of the gap, and the flanges 1011 block the gap to prevent moisture from entering the gap. At this time, the flanges 1011 of the baffle 101 cooperate with the handle 2 to prevent the shielding member from moving circumferentially.

[0044] like Figure 5 Shown and Figure 6 As shown, the handle 2 includes a receiving slot 202 that opens toward the kettle body and the lower housing 4. The opening toward the lower housing 4 communicates with the mounting compartment 400. The conductive member 6 and the outlet of the wiring channel 201 are located within the receiving slot 202. The conductive member 6 extends from the outlet of the wiring channel 201, passes through the opening of the receiving slot 202 toward the lower housing 4, and enters the mounting compartment 400. The user can observe the conductive member 6 through the opening toward the kettle body, so the blocking piece 101 blocks the opening toward the kettle body.

[0045] During the installation process, the installation method of the baffle 101 mainly depends on the size of the installation slot opening.

[0046] When the width of the blocking piece 101 is greater than the width of the receiving groove 202, as shown in FIG. Figure 7 The conductive member 6 is located in the receiving groove 202 , and the blocking piece 101 is located outside the receiving groove 202 . The blocking piece 101 is located between the handle 2 and the kettle body to shield the conductive member 6 .

[0047] When the width of the blocking piece 101 is equal to the width of the receiving groove 202, as shown in FIG. Figure 8 The baffle 101 and the conductive member 6 are both located within the receiving groove 202. The baffle 101 abuts the sidewalls of the receiving groove 202 in the width direction. The baffle 101 is located between the handle 2 and the kettle body, thereby shielding the conductive member 6. The abutment of the baffle 101 against the sidewalls of the receiving groove 202 prevents circumferential movement of the shielding member, ensuring reliable installation. During use and cleaning, moisture must first pass through the gap between the handle 2 and the kettle body, and then through the gap between the receiving groove 202 and the baffle 101, before entering the receiving groove 202. This further prevents moisture from entering the handle 2, improving reliability.

[0048] On the other hand, as the height of the receiving groove 202 varies, the height matching between the blocking piece 101 and the receiving groove 202 also varies.

[0049] When the blocking piece 101 is higher than the receiving groove 202 , the blocking piece 101 generally cannot be located in the receiving groove 202 , and the blocking piece 101 can directly cover the receiving groove 202 in terms of height.

[0050] When the baffle 101 is at the same height as the receiving groove 202, the baffle 101 can be flush with the upper wall of the receiving groove 202. When the baffle 101 is located in the receiving groove 202, the upper edge of the baffle 101 can abut against the upper wall of the receiving groove 202.

[0051] When the baffle 101 is lower than the receiving groove 202, the user can see the conductive member 6 from the gap on the upper side of the baffle 101, which may still affect the aesthetics of the liquid heater. Figure 9 As shown, the top of the baffle 101 is folded outwards and abuts against the side of the receiving groove 202 facing the kettle body, reducing the gap between the upper side of the baffle 101 and the receiving groove 202, making it difficult for the user to see the conductive member 6. Figure 10 As shown, the baffle 101 as a whole can also be tilted toward the outside of the kettle body, so that as the height increases, the distance between the baffle 101 and the accommodating groove 202 becomes smaller and smaller, making it difficult for the user to see the conductive part 6 through the gap on the upper side of the baffle 101.

[0052] In the second form, the wiring channel 201 is located entirely between the kettle body 3 and the handle 2, and the conductive member 6 located on the upper side of the lower shell 4 is exposed to the kettle body. Therefore, the above-mentioned baffle 101 is located between the above-mentioned handle 2 and the kettle body to shield the above-mentioned conductive member 6. The conductive member 6 can be located in the gap between the handle 2 and the kettle body and protrude from the connecting surface 210. The conductive member 6 can extend from the upper side of the handle 2 along the connecting surface 210 to the installation compartment 400, and the baffle 101 is located between the handle 2 and the kettle body to shield and protect the conductive member 6. In this case, the exposed length of the conductive member 6 is longer than the solution in which the wiring channel 201 is located within the grip 220, so the length of the baffle 101 is relatively long. Furthermore, the baffle 101 has flanges 1011 on both sides of the gap. The above-mentioned flanges 1011 shield the above-mentioned gap and prevent moisture from entering the gap. The flanges 1011 of the baffle 101 cooperate with the handle 2 to prevent the shielding member from moving circumferentially. In another embodiment, the handle 2 includes a receiving groove 202 with an opening toward the kettle body and the lower shell 4, the opening toward the lower shell 4 is connected to the installation chamber 400, the conductive member 6 and the outlet of the wiring channel 201 are located in the receiving groove 202, the conductive member 6 is connected to the installation chamber 400 along the receiving groove 202, and the blocking piece 101 blocks the opening toward the kettle body.

[0053] In actual use, it is also necessary to consider the positional relationship between the kettle body and the lower shell 4, and the impact on the assembly relationship of its shielding parts. For the current common liquid heaters, the upper edge of the lower shell 4 is generally located on the bottom surface of the kettle body. At this time, the installation chamber 400 is composed of the bottom surface of the kettle body and the lower shell 4. For the shielding part, the baffle of the shielding part is located outside the installation chamber 400. The baffle of the shielding part is used to shield the side wall of the kettle body, and the visible area inside the installation chamber 400 is covered by the annular ring 102. However, for possible future shapes, the upper edge of the lower shell 4 and the surrounding side surfaces of the kettle body, the corresponding installation chamber 400 is composed of the bottom surface of the kettle body, the surrounding side surfaces of the kettle body and the lower shell 4. At this time, the baffle of the shielding part can be partially located inside the installation chamber 400, and the annular ring 102 is still located inside the installation chamber 400 to cover the visible area.

[0054] When installing the annular ring 102 of the shielding member, the installation and positioning method of the annular ring 102 depends on the bottom structure of the kettle body, the structure of the lower shell 4 and the positional relationship with the heating assembly 5.

[0055] For a liquid heater in which the heating component is installed under the kettle body, when the bottom of the kettle body extends downward to form a connecting portion, the heating component 5 is installed on the connecting portion. This includes the case where the heating component participates in forming the kettle bottom connecting portion, the heating component 5 is in contact with the liquid in the kettle; and also includes the case where the connecting portion is formed by the kettle body itself, and the heating component is not in contact with the liquid in the kettle. Regardless of the structure, the connecting portion protrudes from the bottom of the kettle, and the annular ring 102 is sleeved on the outside of the connecting portion, thereby limiting the horizontal movement of the annular ring 102. During installation, leave a gap between the annular ring 102 and the heating component 5 as much as possible to prevent the annular ring 102 from contacting the heating component 5. The inner diameter of the annular ring 102 is smaller than the outer diameter of the heating component 5, so that during the installation process, the heating component 5 plays a role in preventing the annular ring 102 from falling.

[0056] For a flat-bottomed kettle body, the bottom surface of the kettle body is flat, and the heating component is directly connected to the bottom surface of the kettle body. In this case, the annular ring 102 can abut against the lower shell 4 using the circumference and the lower end surface, thereby achieving support and positioning of the shielding member.

[0057] In actual use, if the kettle body is made of glass, plastic is typically used as the shielding member to prevent damage to the glass body during assembly. Therefore, the annular ring 102 should be kept as close to the heating assembly 5 as possible to prevent melting and damage during heating. This includes both horizontal and vertical spacing between the annular ring 102 and the heating assembly 5; satisfying either requirement is sufficient.

[0058] For the liquid heater mentioned above in which the heating element is installed under the kettle body, due to the presence of the connection part, the heating element is more protruding than the flat-bottomed kettle body, so the liquid heater with the heating element installed under the kettle body is preferably realized with a height spacing. Specifically, the above-mentioned installation bin 400 is provided with a support structure 1024, and the above-mentioned support structure 1024 abuts against the lower end surface of the above-mentioned annular ring 102. The support structure 1024 is used to longitudinally support the annular ring 102 to prevent the annular ring 102 from being close to the heating element 5 in height. Furthermore, in order to prevent the shielding member from shaking up and down after installation, the above-mentioned support structure 1024 can support the annular ring 102 to abut against the ground of the kettle body 3. Horizontal limitation can also be achieved by abutting the outer side of the annular ring 102 against the lower shell 4.

[0059] For the flat-bottomed kettle body mentioned above, the heating assembly 5 is placed close to the bottom of the kettle, making it difficult to create vertical spacing. Therefore, creating horizontal spacing is prioritized. For example, the inner diameter of the annular ring 102 can be larger than the outer diameter of the liquid heater. The outer side of the annular ring 102 abuts against the lower shell 4 to achieve horizontal positioning, while the support structure 1024 within the installation compartment 400 abuts against the lower end surface of the annular ring 102 to provide longitudinal support.

[0060] The support structure 1024 of the above-mentioned lower shell 4 can be in various forms, including but not limited to support ribs extending upward from the inner wall of the lower shell 4 or the bottom wall of the lower shell 4, or a support ring extending inward from the inner wall of the lower shell 4, or a support column extending upward from the inner wall or bottom wall, etc.

[0061] When the lower end of the annular ring 102 abuts against the support structure 1024, the conductive member 6 may be blocked from entering the installation chamber 400. Figure 11 As shown, the annular ring 102 supports a protrusion 1021 downward along the outer edge, and the support protrusion 1021 abuts against the lower shell 4. The support protrusion 1021 also has a first notch 1022, which is located on the lower side of the shielding piece 101. The conductive member 6 enters the installation compartment 400 through the first notch 1022.

[0062] like Figure 12 As shown, the upper edge of the side wall of the lower shell 4 is recessed downward to form a receiving opening, which is used to accommodate the shielding member. The shielding member can use the receiving opening to limit and position, thereby further improving the convenience of installation. Specifically, the shielding member passes through the receiving opening and folds upward to form the above-mentioned blocking piece 101. The shielding member is provided with two second notches 1023 at the receiving opening. The side walls of the lower shell 4 are located in the second notches 1023 on both sides of the shielding member, thereby limiting the position of the shielding member. Furthermore, the conductive member 6 can pass through the receiving opening to enter the above-mentioned installation bin 400. The shielding member passes through the receiving opening and folds upward to form the above-mentioned blocking piece 101, thereby shielding the conductive member 6. On the other hand, the lower shell 4 can also be provided with a wiring opening on the lower side of the receiving opening. The conductive member 6 can pass through the wiring opening on the lower side of the receiving opening to enter the above-mentioned installation bin 400.

[0063] In the liquid heater of this embodiment, the kettle body is preferably made of glass. Glass material can ensure the transparency and visibility of the kettle body, and glass material can also withstand high temperatures during heating. The conductive member 6 can be conductive hardware or wires, etc. The above-mentioned lower shell 4 can be bowl-shaped or basin-shaped as a whole, and the lower shell 4 is buckled on the bottom of the kettle body 3 to form an installation compartment 400. The bottom of the above-mentioned kettle body is provided with a heating component 5, and the lower shell 4 can be fixed by bolting to the heating component 5. The heating component 5 may include a heat-conducting plate fixed to the bottom surface of the kettle body or the connecting part of the kettle body, and a heating element such as a heating tube or a heating film is also provided below the heat-conducting plate.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
