Abstract
Description
Technical Field
[0001] The utility model relates to the field of household appliances, in particular to a liquid heater. Background Art
[0002] The electric kettles currently on the market are made of metal and non-metal materials. Metal materials such as stainless steel kettle bodies are sturdy and durable, but cannot meet the visual needs of users; non-metal materials such as glass kettle bodies are divided into two types. One is a glass kettle body with a metal heating plate installed at the bottom opening, and the kettle body and the heating plate are connected and sealed with silicone glue. Consumers have safety concerns about long-term boiling water with silicone glue; the other is a full glass kettle body with a closed bottom. To achieve heating of this type of kettle body, the existing technology can use two methods to heat the kettle body: upper heat source and lower heat source.
[0003] For example, the existing patent CN202320138915.3 discloses a heating plate assembly structure for an all-glass electric kettle. The heating plate is integrated with the all-glass kettle body, and the heating plate is tightly attached to the outer bottom wall of the kettle body, which can avoid the problem of heavy metal pollution during the boiling process. However, this solution has high requirements on the flatness of the fitting surface of the kettle body and the heating plate. Otherwise, it is easy for the heating plate to have poor contact with the bottom of the kettle body, resulting in uneven heating; and this solution requires the use of an additional tightening mechanism to tighten the heating plate, resulting in a complex overall structure of the kettle body assembly and high cost.
[0004] Furthermore, the existing patent CN202221217479.0 discloses a heating container that adopts a downward-placed heat source. After the glass pot body is removed, the heating component on the base still has residual temperature and can directly contact people, posing a safety hazard. Utility Model Content
[0005] The utility model provides a liquid heater, which aims to solve the problems of the existing electric kettle in which a heating plate is attached to the bottom of the kettle body, which has high requirements on the flatness of the bottom of the kettle body and requires an additional tightening mechanism to tighten the heating plate, resulting in a complex structure and high cost.
[0006] The utility model discloses a liquid heater, comprising a kettle body assembly and a power base which are separately arranged, the kettle body assembly and the power base being electrically connected via a coupling assembly, the kettle body assembly comprising an all-glass kettle body, an insulated heating assembly and a shell assembly, the insulated heating assembly comprising a support member provided with an accommodating cavity and a heating element arranged in the accommodating cavity, the support member having an upwardly extending annular side wall, the all-glass kettle body and the shell assembly clamping the support member, the upper edge of the annular side wall abutting against the bottom of the all-glass kettle body to form a gap between the heating element and the bottom of the all-glass kettle body.
[0007] The liquid heater of the present invention also has the following additional technical features:
[0008] The shell assembly includes an outer shell and a bottom cover, the lower end of the outer shell is connected to the bottom cover, the upper end of the outer shell is supported on the outer side wall of the all-glass pot body, and the bottom cover supports the support member so that the outer shell and the bottom cover clamp the all-glass pot body and the support member up and down.
[0009] An inwardly contracted annular groove is provided at the upper end of the all-glass kettle body, and the top edge of the shell is clamped tightly in the annular groove.
[0010] The shell assembly includes an outer shell and a bottom cover, the bottom cover includes a bottom plate and support ribs extending upward from the bottom plate, an upper coupler is provided between the bottom plate and the support member, the support ribs are arranged around the upper coupler, and the support ribs cooperate with the upper coupler to support the support member.
[0011] The shell assembly includes an outer shell and a bottom cover. The support member is provided with a concave annular accommodating cavity and an upward concave air-avoiding cavity surrounded by the accommodating cavity. The accommodating cavity is used to accommodate the heating element. The bottom cover supports the bottom surface of the accommodating cavity. An upper coupler is provided between the bottom cover and the support member, and the upper coupler is arranged in the air-avoiding cavity.
[0012] The upper coupler is provided with a temperature sensing portion, and a avoidance hole is provided at the center of the support member, and the temperature sensing portion abuts against the bottom of the all-glass pot body through the avoidance hole.
[0013] A temperature detecting element is fixed on the bottom cover, and the temperature detecting element abuts against the bottom of the full-glass kettle body through the opening at the top of the cavity.
[0014] An open groove is provided on one side of the shell, and the shell is stretched and deformed through the open groove to wrap the full glass pot body. Oppositely arranged convex buckles are provided on both sides of the notch of the open groove, and screw holes are provided on the convex buckles.
[0015] The shell is provided with a viewing window, through which the interior of the all-glass kettle body can be viewed.
[0016] The gap is no greater than 10 mm.
[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0018] 1. The liquid heater of the present invention adopts an insulated heating assembly to heat the kettle body. The heating element does not need to be set in close contact with the kettle body, and the flatness requirement for the bottom of the kettle body is low, which can reduce the processing accuracy requirement of the kettle body and help save costs; moreover, the support of the insulated heating assembly is clamped by the kettle body and the shell assembly, and the additional fixing structure can be omitted, which can simplify the structural configuration and promote the compactness between the structures. At the same time, it can reduce the overall axial size of the kettle body assembly and realize the lightweight of the kettle body assembly.
[0019] It can be understood that insulated heating means that there is a certain gap between the heating element and the bottom of the kettle body. The heat generated by the heating element is transferred to the kettle body through thermal radiation, thereby heating the liquid in the kettle body. Although there is a certain gap, the gap is small. Compared with the setting of the heating plate fitting the kettle body, the heat transfer efficiency is not much different, so the heating efficiency can be guaranteed. Moreover, through radiation heating, the uniformity of heating can be improved. When stewing ingredients in the kettle, it is conducive to the full stewing of the ingredients and improves the taste.
[0020] 2. To ensure the clamping effect of the support, the outer shell of the shell assembly provides a downward clamping force to the kettle body, and the bottom cover of the shell assembly supports the support and provides an upward clamping force to the support, so that the shell and the bottom cover clamp the all-glass kettle body and the support up and down, which not only realizes the assembly of the shell assembly and the kettle body but also clamps the support, making the overall assembly of the kettle body assembly firm and compact, and ensuring the reliability of the use of the kettle body assembly.
[0021] 3. In order to further enhance the clamping force, an inward-retracting annular groove is provided at the upper end of the all-glass kettle body. By tightening the top edge of the shell in the annular groove, the shell can fully clamp the kettle body, thereby promoting the clamping of the kettle body and the bottom cover to support the parts, thus preventing the support parts from shaking inside and affecting the heating effect of the heating element.
[0022] 4. When the bottom cover includes a bottom plate and support ribs extending upward from the bottom plate, and an upper coupler is provided between the bottom plate and the support member, the support ribs are arranged around the upper coupler, and the support ribs and the upper coupler can be used to cooperate to support the support member, that is, the support ribs are used to support the peripheral area of the support member, and the upper coupler is used to support the middle area of the support member, so that the center and edge of the support member are supported. The support range is large, which can enhance the stability of the support and help keep the support member stable, so that the heat of the heating element can be evenly radiated to the kettle body, thereby improving the uniformity of heating.
[0023] Furthermore, the upper coupler is provided with a temperature sensing part, and the center of the support is provided with an avoidance hole. The temperature sensing part abuts against the bottom of the all-glass kettle body through the avoidance hole. By integrating the temperature sensing part on the upper coupler, the provision of an additional temperature sensing element can be omitted, and the installation of the temperature sensing element is omitted, which can simplify the structural configuration and installation steps. The water temperature is measured by contacting the temperature sensing part with the bottom of the kettle body, and the temperature measurement is accurate, which is conducive to the user obtaining the required drinking temperature and improving the user experience.
[0024] 5. When the support member is provided with a concave annular accommodating cavity and an upward concave air-avoiding cavity surrounded by the accommodating cavity, the support of the support member can be achieved by supporting the bottom surface of the accommodating cavity by the bottom cover, and the upper coupler is arranged in the air-avoiding cavity. On the one hand, the bottom surface of the accommodating cavity has a certain width and has a large contact area with the bottom cover, and the supporting effect can be guaranteed when supported only by the bottom cover. Therefore, there is no requirement for whether the upper coupler plays a supporting role, which can reduce the installation requirements for the upper coupler; on the other hand, the concave setting of the upper coupler improves space utilization, which can further promote the compactness between structures, reduce the overall axial size of the shell assembly, and realize the miniaturization of the shell assembly.
[0025] Furthermore, a temperature detecting element is fixed on the bottom cover, and the temperature detecting element is in contact with the bottom of the all-glass kettle body through the opening at the top of the avoidance cavity. The temperature detecting element can also be installed in the space of the avoidance cavity, which further improves the space utilization rate. Moreover, the temperature is measured accurately by the temperature detecting element directly contacting the kettle body, which is conducive to enabling users to obtain the required drinking temperature and improving the user experience.
[0026] 6. An open groove is provided on one side of the shell. When the kettle body is installed, the upper end of the shell can be stretched through the open groove to have enough space to allow the upper end of the kettle body to extend out, and then the open groove can be tightened and locked with screws. This facilitates the installation of the kettle body and helps the shell to tighten the kettle body, ensuring the firmness of the kettle body assembly.
[0027] 7. In order to ensure the visual effect, a window is provided on the outer shell, through which the user can view the interior of the all-glass kettle, which can enhance the user's visual experience. The use of the window can avoid the use of transparent materials as the entire outer shell, which limits the material selection of the outer shell, making the configuration of the outer shell more flexible.

[0043] like Figures 1 to 5As shown, the present application provides a liquid heater, including a separately arranged kettle body assembly 10 and a power base 11, the kettle body assembly 10 and the power base 11 are electrically connected through a coupling assembly, the kettle body assembly 10 includes an all-glass kettle body 13, an insulated heating assembly and a shell assembly, the insulated heating assembly includes a support member 14 provided with an accommodating cavity 142 and a heating element 15 arranged in the accommodating cavity 142, the support member 14 has an upwardly extending annular side wall 141, the all-glass kettle body 13 and the shell assembly clamp the support member 14, the upper edge of the annular side wall 141 abuts against the bottom of the all-glass kettle body 13, so that a gap is formed between the heating element 15 and the bottom of the all-glass kettle body 13.
[0044] The liquid heater of the present invention adopts an insulated heating assembly to heat the all-glass kettle body 13. The heating element 15 does not need to be arranged in contact with the all-glass kettle body 13. The flatness requirement for the bottom of the all-glass kettle body 13 is relatively low, which can reduce the processing accuracy requirement of the all-glass kettle body 13 and help save costs; moreover, the support member 14 of the insulated heating assembly is clamped by the all-glass kettle body 13 and the shell assembly, and the additional fixing structure can be omitted, which can simplify the structural configuration and promote the compactness between the structures. The overall axial size of the kettle body assembly 10 can be reduced, thereby realizing the lightweight of the kettle body assembly 10.
[0045] It can be understood that insulated heating refers to the presence of a certain gap between the heating element 15 and the bottom of the all-glass kettle body 13. The heat generated by the heating element 15 is transferred to the all-glass kettle body 13 through thermal radiation, thereby heating the liquid in the all-glass kettle body 13. Although there is a certain gap, the gap is small. Compared with the setting of the heating plate fitting the all-glass kettle body 13, the heat transfer efficiency is not much different, thus ensuring heating efficiency. Moreover, through radiant heating, the uniformity of heating can be improved. When stewing ingredients in the all-glass kettle body 13, it is conducive to the full stewing of the ingredients and improves the taste. Preferably, the gap between the heating element 15 and the bottom of the all-glass kettle body 13 is no more than 10mm to shorten the heat conduction path and improve heating efficiency.
[0046] Specifically, the kettle body assembly 10 is provided with an upper coupler 12, and the power base 11 is provided with a lower coupler. When the kettle body assembly 10 is correctly placed on the power base 11, the upper coupler 12 and the lower coupler are plugged into each other, and then the switch is turned on to heat the liquid in the all-glass kettle body 13. The all-glass kettle body 13 is made of glass to form an integrated structure, with an open upper end and a closed lower end. The upper opening is provided with a kettle lid, which is used to cover the opening when boiling water or making tea to prevent liquid from splashing. The support member 14 forms a accommodating cavity 142, which is recessed relative to the bottom of the all-glass kettle body 13. The heating element 15 is sunken to form a heat insulation effect.
[0047] It can be understood that the support member 14 not only serves as the mounting structure of the insulated heating component, provides internal accommodation for the heating element 15, and cooperates with the all-glass kettle body 13 and the shell assembly outward, but also allows the heating element 15 to be installed in a relatively closed environment (compared to the existing heating plate exposed in the bottom shell of the kettle), that is, the annular side wall 141 and the all-glass kettle body 13 enclose the heating element 15, which is beneficial to concentrate the heat of the heating element 15 to radiate to the all-glass kettle body 13, reduce heat loss, and improve heating efficiency. At the same time, it can prevent the heat of the heating element 15 from being transferred to the shell assembly, prevent the shell assembly from thermal deformation or scalding the user when the temperature is high, and improve the reliability and safety of the product.
[0048] As a preferred embodiment, the shell assembly includes an outer shell 17 and a bottom cover 18, the lower end of the outer shell 17 is connected to the bottom cover 18, the upper end of the outer shell 17 is supported on the outer wall of the all-glass pot body 13, and the bottom cover 18 supports the support member 14 so that the outer shell 17 and the bottom cover 18 clamp the all-glass pot body 13 and the support member 14 up and down.
[0049] To ensure the clamping effect of the support member 14, the shell 17 of the shell assembly provides a downward clamping force to the full glass kettle body 13, and the bottom cover 18 of the shell assembly supports the support member 14 and provides an upward clamping force to the support member 14, so that the shell 17 and the bottom cover 18 clamp the full glass kettle body 13 and the support member 14 from top to bottom, which not only realizes the assembly of the shell assembly and the full glass kettle body 13 but also clamps the support member 14, making the overall assembly of the kettle body assembly 10 firm and compact, and ensuring the reliability of the use of the kettle body assembly 10. Figure 3 As shown, the housing 17 and the bottom cover 18 can be fixed by screws 16 .
[0050] Further, such as Figure 3 or Figure 5 As shown, the upper end of the all-glass kettle body 13 is provided with an inward-contracted annular groove 131, and the top edge of the shell 17 is clamped in the annular groove 131, which can enable the shell 17 to fully clamp the all-glass kettle body 13, thereby promoting the all-glass kettle body 13 and the bottom cover 18 to clamp the support part 14, and prevent the support part 14 from shaking inside and affecting the heating effect of the heating element 15.
[0051] In order to realize the clamping of the support member 14 , it can be achieved by any of the following methods.
[0052] In the first embodiment, the shell assembly includes an outer shell 17 and a bottom cover 18, the bottom cover 18 includes a bottom plate 182 and a support rib 183 extending upward from the bottom plate 182, an upper coupler 12 is provided between the bottom plate 182 and the support member 14, the support rib 183 is arranged around the upper coupler 12, and the support rib 183 cooperates with the upper coupler 12 to support the support member 14.
[0053] like Figure 2 and Figure 3 As shown, the support ribs 183 are used to support the peripheral area of the support member 14, and the upper coupler 12 is used to support the middle area of the support member 14, so that the center and edge of the support member 14 are supported. The support range is large, which can enhance the stability of the support and help keep the support member 14 stable, so that the heat of the heating element 15 can be evenly radiated to the all-glass pot body 13, thereby improving the uniformity of heating.
[0054] In this embodiment, the bottom cover 18 forms a space for accommodating the upper coupler 12, and the upper coupler 12 is arranged below the support member 14; the support ribs 183 are preferably arranged corresponding to the peripheral area of the support member 14, and the support ribs 183 can be annular support ribs 183 or a discontinuous structure, such as each support rib 183 is arc-shaped, and multiple support ribs 183 are distributed at intervals along the circumference of the bottom plate 182. Figure 3 As shown, this example adopts an annular supporting rib 183 , and a notch 184 is provided on one side of the supporting rib 183 , so that the wiring of the heating element 15 can be connected to the upper coupler 12 through the notch 184 .
[0055] In this embodiment, the insulated heating component is an electric ceramic heating component, the support member 14 is an electric ceramic heating plate, and the heating element 15 is a heating wire arranged in the electric ceramic heating plate.
[0056] In one embodiment, the upper coupler 12 is provided with a temperature-sensing portion, and a relief hole 143 is provided in the center of the support member 14. The temperature-sensing portion contacts the bottom of the all-glass kettle body 13 through the relief hole 143. By integrating the temperature-sensing portion into the upper coupler 12, the installation of an additional temperature-sensing component is eliminated, simplifying the structural configuration and installation steps. The temperature-sensing portion contacts the bottom of the all-glass kettle body 13 to measure the water temperature accurately, helping users obtain the desired drinking temperature and improving the user experience.
[0057] In the second embodiment, the shell assembly includes an outer shell 17 and a bottom cover 18. The support member 14 is provided with a concave annular accommodating cavity 142 and an upward concave air-avoiding cavity 144 surrounded by the accommodating cavity 142. The accommodating cavity 142 is used to accommodate the heating element 15. The bottom cover 18 supports the bottom surface of the accommodating cavity 142. An upper coupler 12 is provided between the bottom cover 18 and the support member 14. The upper coupler 12 is arranged in the air-avoiding cavity 144.
[0058] like Figure 4As shown, on the one hand, the bottom surface of the accommodating cavity 142 has a certain width and a large contact area with the bottom cover 18. The supporting effect can be guaranteed when supported only by the bottom cover 18. Therefore, there is no requirement for whether the upper coupler 12 plays a supporting role, which can reduce the installation requirements of the upper coupler 12; on the other hand, the concave setting of the upper coupler 12 improves space utilization, further promotes the compactness between structures, reduces the overall axial size of the shell assembly, and realizes the miniaturization of the shell assembly.
[0059] In this embodiment, the air-insulated heating component is a light wave heating component, the support member 14 is a heat shield, and the heating element 15 is a light wave tube. The light wave tube is annular or C-shaped, and can better cooperate with the accommodating cavity 142 under the premise of meeting the heating effect. Figure 5 As shown, the support member 14 may be in the form of a double-layer heat insulation cover to enhance the heat insulation effect.
[0060] Furthermore, a mounting boss is provided on the bottom wall of the accommodating cavity 142, and the light wave tube is fixed on the mounting boss. The mounting boss can be used to raise the light wave tube to reduce the gap between the light wave tube and the bottom of the all-glass pot body 13, thereby improving the heat transfer efficiency. Moreover, the light wave tube is supported by the mounting boss, which can reduce the area of direct contact between the light wave tube and the bottom wall of the support 14, thereby preventing the heat of the light wave tube from being transferred outward through the support 14, thereby enhancing the thermal insulation effect. There are multiple mounting bosses spaced apart along the circumference, and each mounting boss is provided with a socket, which can be clamped on the light wave tube by a clamping ring 19 and then the two ends of the clamping ring 19 are inserted into the socket to achieve fixation. Multiple clamping rings 19 are arranged in a one-to-one correspondence with multiple mounting bosses, which can ensure that the light wave tube is at the same height as a whole, thereby improving the uniformity of heating the all-glass pot body 13.
[0061] In one embodiment, a temperature detection element 20 is fixed on the bottom cover 18, and the temperature detection element 20 is in contact with the bottom of the full glass pot body 13 through the opening at the top of the cavity 144. Figure 5 As shown, the temperature detecting element 20 is fixed by a fixing bracket 21, and the temperature detecting element 20 is installed by utilizing the space of the cavity 144, thereby further improving the space utilization rate. Moreover, the temperature detecting element 20 directly contacts the all-glass kettle body 13 for temperature measurement, and the temperature measurement is accurate, which is conducive to enabling users to obtain the required drinking temperature and improving the user experience.
[0062] It can be understood that the temperature sensing part and the temperature detecting element 20 of the above-mentioned embodiment are directly in contact with the all-glass kettle body 13 to measure the water temperature. In other embodiments, the temperature sensing part and the temperature detecting element 20 can also indirectly measure the water temperature by measuring the temperature of the support 14. In this case, it is only necessary to make the temperature sensing part and the temperature detecting element 20 contact with the support 14.
[0063] On the basis of the above implementation mode, Figure 3 or Figure 5As shown, a through hole 181 is provided at the bottom of the bottom cover 18 , and the bottom of the upper coupler 12 is exposed through the through hole 181 so as to be connected to the lower coupler on the power base 11 .
[0064] Based on the above embodiment, an open groove 171 is provided on one side of the shell 17, and the shell 17 is stretched and deformed through the open groove 171 to wrap the full glass pot body 13. The open groove 171 has relatively arranged protrusions 172 on both sides of the notch, and screw holes 173 are provided on the protrusions 172.
[0065] like Figure 3 or Figure 5 As shown, the open groove 171 runs through the top to the bottom of the outer shell 17. During installation, the all-glass pot body 13 can be inserted into the outer shell 17 from bottom to top. During the upward process of the all-glass pot body 13, the top of the outer shell 17 is pulled open by enlarging the open groove 171 so that the upper end of the all-glass pot body 13 extends out of the outer shell 17, and then the open groove 171 is tightened, and the screw 16 is locked into the screw hole 173 to make the outer shell 17 clamp the all-glass pot body 13.
[0066] The housing 17 can be made of plastic or metal. To meet the user's visual needs, a hollow window 174 is provided on the housing 17. When the electric kettle is in operation, the user can see the interior of the all-glass kettle body 13 through the window 174, which is conducive to improving the user experience. The use of the window 174 can avoid the restriction of the material selection of the housing 17 by using a transparent material as a whole, thereby making the configuration of the housing 17 more flexible. The kettle body assembly 10 also includes a handle 22, which can be fixed to the protruding buckle 172 to facilitate the user to pick up the kettle body assembly 10.
[0067] The liquid heater of the present application can be an electric kettle, a health kettle, etc., which can be used to boil water, make tea, cook white fungus and other beverages, and can enrich the user's daily drinking needs.
