Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a liquid heating device. Background Art

[0002] The glass health pots currently on the market are Figure 1 As shown, the bottom opening of the glass container body 20a has an inwardly extending connecting rib 210a, and the heating plate 30a is connected to the connecting rib 210a to close the opening. A container bottom cover 10a is provided around the bottom of the glass container body 20a. The container bottom cover 10a supports the glass container body 20a and forms an installation cavity under the glass container body 20a to accommodate components such as the thermostat. However, since the connecting rib 210a is also made of glass, when the user roughly presses Figure 1 When viewing the glass health-preserving kettle from the direction indicated by the middle arrow, it is easy to see the internal structure of the installation cavity through the gap between the connecting ribs 210a on the periphery of the heating plate 30a, the bottom cover 10a of the container and the heating plate 30a, which affects the aesthetics.

[0003] In order to cover up the ugliness in the related art, one way is to print a layer of concealing coating on the connecting ribs, but this will increase the cost. Another way is to install a plastic baffle on the bottom cover of the container, using the plastic baffle to support the glass container body and block the line of sight, but this will increase the processing steps of the bottom cover of the container, and the supporting strength of the plastic baffle is not very sufficient. Utility Model Content

[0004] Therefore, an object of the present invention is to provide a container bottom cover and a liquid heating device to at least solve one of the problems existing in the above-mentioned prior art or related art.

[0005] A first embodiment of the present invention provides a container bottom cover for supporting the bottom of a container body of a liquid heating device. The container bottom cover comprises: a bottom cover sidewall having an air interlayer within the bottom cover sidewall, the upper surface of the bottom cover sidewall being used to circumferentially support the bottom edge of the container body; and a bottom cover bottom wall located at the inner bottom of the bottom cover sidewall. The bottom cover sidewall and the bottom cover bottom wall define an installation cavity for accommodating a thermostat. The bottom cover sidewall and the bottom cover bottom wall are integrally formed.

[0006] The container bottom cover provided by the embodiment of this aspect has a bottom cover side wall and a bottom cover bottom wall formed in one piece, and the bottom cover side wall has a certain thickness, and has an air interlayer inside. The bottom cover side wall with a certain thickness is used to support the bottom edge of the container body, and the support stability is good. Moreover, when the container bottom cover is supported on the bottom of the glass container body, compared with the bottom cover side wall with a single thin wall supported on the bottom edge of the glass container body, the thicker bottom cover side wall can extend toward the location of the heating plate, and can cover more of the connecting ribs below, shortening the gap between the bottom cover side wall and the heating plate, so that when the user looks down at the glass container body, the bottom cover side wall can be seen through the connecting ribs, and it is not easy to see the inside of the installation cavity, thereby reducing the probability of the user seeing the inside of the installation cavity through the connecting ribs at the bottom of the glass container body, thereby playing a role in concealing ugliness. In addition, the container bottom cover is an integrally formed structure and is easy to process.

[0007] In some embodiments, the side wall of the bottom cover includes: a top wall of the bottom cover, which is used to circumferentially support the bottom edge of the container body; an inner wall of the bottom cover, which connects the inner edge of the top wall of the bottom cover and the outer edge of the bottom wall of the bottom cover; an outer wall of the bottom cover, which connects the outer edge of the top wall of the bottom cover and extends downward, and an opening is left between the bottom of the outer wall of the bottom cover and the bottom of the inner wall of the bottom cover, and an air layer is formed between the inner wall of the bottom cover and the outer wall of the bottom cover, and the air layer is connected to the outside through the opening.

[0008] In these embodiments, the bottom cover sidewalls comprise a top wall, an inner wall, and an outer wall. The radial cross-section of these three walls is generally gate-shaped, with a downward opening that communicates with the intermediate air layer. This simplifies the structure and conserves material. Furthermore, connecting the outer edge of the bottom cover wall to the lower edge of the inner wall not only enhances the structural strength of the inner wall, ensuring stable support for the container body, but also facilitates the integral molding of the container bottom cover.

[0009] In some embodiments, the bottom cover sidewall further comprises: a plurality of support ribs, the plurality of support ribs being circumferentially spaced apart within the air layer, and each support rib connecting the bottom cover top wall, the bottom cover inner sidewall, and the bottom cover outer sidewall. This can enhance the structural strength of the container bottom cover, thereby providing more stable support for the container body.

[0010] In some embodiments, the surface of the bottom cover side wall facing the inside of the mounting cavity includes an inclined surface extending obliquely toward the middle of the bottom cover wall. Thus, when the bottom cover is supported on the outer periphery of the bottom of the glass container body, the inclined surface extends directly below the gap between the top of the bottom cover side wall and the heating plate. Thus, even when a user is looking vertically downward at the bottom of the glass container body, through the connecting ribs at the bottom of the glass container body and the gap between the top of the bottom cover side wall and the heating plate, they still see the inclined surface of the bottom cover side wall, which enhances the texture and aesthetics of the bottom cover side wall.

[0011] In some embodiments, the bottom cover sidewall has circumferentially distributed shielding ribs on its surface facing the inner side of the mounting cavity. When the bottom cover is supported on the outer periphery of the bottom of the glass container body, the shielding ribs can shield the gap between the top of the bottom cover sidewall and the heating plate from below. Thus, even when a user is looking vertically downward at the bottom of the glass container body, through the connecting ribs at the bottom of the glass container body and the gap between the top of the bottom cover sidewall and the heating plate, they can still see the shielding ribs and the texture of the bottom cover sidewall, resulting in a more aesthetically pleasing appearance.

[0012] In some embodiments, the upper surface of the side wall of the bottom cover is adapted to fit the bottom edge of the container body, thereby facilitating stable support of the container body.

[0013] In some embodiments, a mounting hole is provided on the bottom wall of the bottom cover, and the mounting hole is used to mount the thermostat. The thermostat is fixed on the bottom wall of the bottom cover, and the thermostat has good mounting stability.

[0014] The second aspect of the present invention provides a liquid heating device, which includes: a glass container body, the bottom of the glass container body has an opening, and the opening is provided with a connecting rib extending inward; a heating plate, the heating plate is connected to the edge of the connecting rib and closes the opening; a container bottom cover such as any of the above embodiments, the upper surface of the bottom cover side wall supports the lower surface of the connecting rib located on the outer periphery of the heating plate to shield the interior of the installation cavity.

[0015] The liquid heating device provided in this embodiment, by virtue of having the container bottom cover of any of the aforementioned embodiments, thereby exhibits the beneficial effects of any of the aforementioned embodiments, which will not be further elaborated here. Furthermore, the upper surface of the bottom cover sidewall of the container bottom cover circumferentially supports the glass container body. When a user directs their view toward the bottom of the glass container body, the upper surface of the bottom cover sidewall and the heating plate can block their view, preventing the user from viewing the interior of the installation cavity through the glass container body.

[0016] In some embodiments, a gap is formed between the heating plate and the side wall of the bottom cover in a horizontal direction, and the gap overlaps with a projection of a surface of the side wall of the bottom cover facing the inner side of the installation cavity on a horizontal plane.

[0017] Here, the surface of the bottom cover side wall facing the inner side of the mounting cavity can be extended obliquely to directly below the gap. Alternatively, the surface of the bottom cover side wall facing the inner side of the mounting cavity can be provided with a shielding rib, which extends directly below the gap, so that the projection of the gap on the horizontal plane falls on the surface of the bottom cover side wall facing the inner side of the mounting cavity. In this way, even if the user sees the gap, even through the gap, what they see is the surface of the bottom cover side wall facing the inner side of the mounting cavity or the shielding rib, and the texture of the bottom cover side wall is seen, which improves the aesthetics.

[0018] In some embodiments, the width of the gap ranges from 0.5 mm to 1 mm.

[0019] In these embodiments, the horizontal gap between the bottom cover sidewall and the heating plate is set to a width between 0.5 mm and 1 mm. This prevents the bottom cover sidewall from overheating or even causing adhesive melting due to a too small gap between the two. Furthermore, it prevents the user from easily seeing the interior of the mounting cavity through the gap between the bottom cover sidewall and the heating plate due to a too large gap between the two. The gap between the bottom cover sidewall and the heating plate can be minimized without causing the bottom cover sidewall to become too hot, thereby preventing the user from seeing the interior of the mounting cavity through the gap.

[0020] In some embodiments, the liquid heating device further comprises a thermostat disposed within a mounting cavity of the container bottom cover. The thermostat is screwed to the heating plate and further screwed to the bottom wall of the container bottom cover. Here, the thermostat is simultaneously secured to the heating plate and the bottom wall of the bottom cover, providing a secure mounting. Furthermore, compared to directly attaching the thermostat to the side wall of the container bottom cover, this does not affect the structural strength of the side wall, thereby facilitating stable support of the glass container body by the side wall of the bottom cover.

[0021] In some embodiments, the connecting rib extends from the edge of the opening toward the interior of the glass container body and then downward, and the heating plate is connected to the downwardly extending portion of the connecting rib, so that the side wall of the bottom cover is arranged around the periphery of the heating plate.

[0022] Here, the heating plate is connected to the downward extending part of the connecting rib, which is convenient for connection and helps to sink the heating plate into the installation cavity, so that the top of the bottom cover of the container can also circumferentially surround the heating plate, thereby reducing the probability of the user viewing the periphery of the heating plate and the interior of the installation cavity through the connecting rib.

[0023] Additional aspects and / or advantages of the present general inventive concept will be set forth in part in the following description, and some will be clear from the description or may be learned through practice of the present general inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following will be combined Figure 2 and Figure 6 The container bottom cover 10 and the liquid heating device provided by the embodiment of the present utility model are introduced. Figure 2 The middle arrow indicates a visual direction of a user when looking downward at the liquid heating device.

[0050] like Figure 2 、 Figure 3 and Figure 4 As shown, a first embodiment of the present invention provides a container bottom cover 10 for supporting the bottom of a container body of a liquid heating device. The container bottom cover 10 includes: a bottom cover side wall 110, the interior of the bottom cover side wall 110 having an air interlayer 114, the upper surface of the bottom cover side wall 110 being used to circumferentially support the bottom edge of the container body; a bottom cover bottom wall 120, located at the inner bottom of the bottom cover side wall 110, the bottom cover side wall 110 and the bottom cover bottom wall 120 enclosing an installation cavity 130, which is used to accommodate a thermostat 40; wherein the bottom cover side wall 110 and the bottom cover bottom wall 120 are integrally formed.

[0051] The container bottom cover 10 provided in the embodiment of this aspect has a bottom cover side wall 110 and a bottom cover bottom wall 120 formed in one piece, and the bottom cover side wall 110 has a certain thickness, and has an air interlayer 114 inside. The bottom cover side wall 110 with a certain thickness is used to support the bottom edge of the container body, and the support stability is good. Moreover, when the container bottom cover 10 is supported on the bottom of the glass container body 20, compared with the bottom cover side wall with a single thin wall supported on the bottom edge of the glass container body, the thicker bottom cover side wall 110 can extend toward the location of the heating plate 30, and can cover more of the connecting ribs 210 connected to the heating plate 30 below, shortening the gap between the bottom cover side wall 110 and the heating plate 30, so that when the user looks down at the glass container body 20, the bottom edge of the glass container body is supported by the bottom cover side wall 110. Figure 2 When viewing the glass container body 20 in the direction indicated by the middle arrow, the bottom cover side wall 110 can be seen through the connecting rib 210, while the interior of the mounting cavity 130 is not easily visible. Instead, the user can see the texture of the bottom cover side wall 110, thereby reducing the probability of the user seeing the interior of the mounting cavity 130 through the connecting rib 210 at the bottom of the glass container body 20, thereby achieving a concealing effect.

[0052] In addition, the container bottom cover 10 is an integrally formed structure, which is easy to process. It only requires one container bottom cover 10 to achieve the ugly effect. There is no need to open a new mold for the plastic baffle, nor is there a need for secondary silk-screen processing of the glass container body 20, which reduces development costs.

[0053] Furthermore, in some embodiments, Figure 3 and Figure 5 As shown, the bottom cover side wall 110 includes: a bottom cover top wall 111, which is used to circumferentially support the bottom edge of the container body; a bottom cover inner wall 112, which connects the inner edge of the bottom cover top wall 111 and the outer edge of the bottom cover bottom wall 120; a bottom cover outer wall 113, which connects the outer edge of the bottom cover top wall 111 and extends downward, and an opening 115 is left between the bottom of the bottom cover outer wall 113 and the bottom of the bottom cover inner wall 112, and an air layer 114 is formed between the bottom cover inner wall 112 and the bottom cover outer wall 113, and the air layer 114 is connected to the outside through the opening 115.

[0054] In these embodiments, the bottom cover sidewall 110 comprises a bottom cover top wall 111, a bottom cover inner sidewall 112, and a bottom cover outer sidewall 113. The radial cross-section of the three components is generally gate-shaped, with an opening 115 facing downward and communicating with an intermediate air layer 114. This simplifies the structure and conserves materials. Furthermore, connecting the outer edge of the bottom cover bottom wall 120 to the lower edge of the bottom cover inner sidewall 112 not only strengthens the structural strength of the bottom cover inner sidewall 112, providing stable support for the container, but also facilitates the integral molding of the container bottom cover 10.

[0055] Of course, in other embodiments, the bottom cover inner wall 112 and the bottom cover outer wall 113 can be connected to the bottom cover bottom wall 120, so that the air interlayer 114 does not have an external opening connected to the outside world, or an opening 115 connecting the air interlayer 114 and the outside world is opened on the bottom cover bottom wall 120.

[0056] Furthermore, if Figure 5 As shown, the bottom cover side wall 110 further includes a plurality of support ribs 116, which are circumferentially spaced apart within the air layer 114, and each support rib 116 connects the bottom cover top wall 111, the bottom cover inner side wall 112, and the bottom cover outer side wall 113. This can improve the structural strength of the container bottom cover 10, thereby more stably supporting the container body.

[0057] Of course, multiple support ribs 116 can also be distributed circumferentially on the radially inner side of the bottom cover inner side wall 112 and connected to the bottom cover bottom wall 120, which can also strengthen the strength of the bottom cover side wall 110 and help to stably support the container body.

[0058] To improve the concealing effect, further, in some embodiments, the surface of the bottom cover side wall 110 facing the inner side of the installation cavity 130 includes an inclined surface extending obliquely toward the middle of the bottom cover bottom wall 120 .

[0059] In this way, when the bottom cover 10 of the container is supported on the outer periphery of the bottom of the glass container body 20, the inclined surface can be extended to directly below the gap between the top of the bottom cover side wall 110 and the heating plate 30. In this way, even if the user looks down vertically at the bottom of the glass container body 20, through the connecting ribs 210 at the bottom of the glass container body 20, through the gap between the top of the bottom cover side wall 110 and the heating plate 30, what can be seen is the inclined surface of the bottom cover side wall 110, and what can be seen is the texture of the bottom cover side wall 110, which is aesthetically pleasing.

[0060] In other embodiments, shielding ribs (not shown) may be circumferentially distributed on the surface of the bottom cover side wall 110 facing the inner side of the installation cavity. This allows the shielding ribs to shield the gap between the top of the bottom cover side wall 110 and the heating plate 30 from below when the bottom cover 10 is supported on the outer periphery of the bottom of the glass container body 20. This allows the user to view the bottom of the glass container body 20 vertically downward through the connecting ribs 210 at the bottom of the glass container body 20 and through the gap between the top of the bottom cover side wall 110 and the heating plate 30. This improves the aesthetics of the bottom cover side wall 110.

[0061] In some embodiments, the upper surface of the bottom cover sidewall 110 is adapted to fit the bottom edge of the container body, thereby facilitating stable support of the container body.

[0062] In some embodiments, as Figure 4 、 Figure 5 and Figure 6 As shown, a mounting hole 121 is provided on the bottom wall 120 of the bottom cover, and the mounting hole 121 is used to mount the thermostat 40 , which is conducive to stably mounting the thermostat 40 in the mounting cavity 130 .

[0063] As an example, Figure 4 and Figure 5 As shown, there are three mounting holes 121 , and three first screws 420 are inserted into the thermostat 40 through the corresponding mounting holes 121 .

[0064] Furthermore, in some embodiments, the container bottom cover 10 is a plastic part, which is light, low in cost, and easy to process. Of course, the container bottom cover 10 can also be made of other materials, such as metal, which has a good texture.

[0065] like Figure 2 、 Figure 3 and Figure 4As shown, a second embodiment of the present invention provides a liquid heating device, comprising a container body, a heating plate 30, and a container bottom cover 10 as described in any of the above embodiments. The bottom of the glass container body 20 has an opening, and a connecting rib 210 extending inward is provided at the opening; the heating plate 30 is connected to the edge of the connecting rib 210 and closes the opening; the upper surface of the bottom cover side wall 110 supports the lower surface of the connecting rib 210 located at the periphery of the heating plate 30.

[0066] The liquid heating device provided in this embodiment has the container bottom cover 10 of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0067] Furthermore, the container body is a glass container body 20. This improves the appearance. In this case, the upper surface of the bottom cover side wall 110 supports the lower surface of the connecting rib 210 located on the periphery of the heating plate 30. When the user looks toward the bottom of the glass container body 20, the upper surface of the bottom cover side wall 110 and the heating plate 30 can block the view, preventing the user from seeing through the glass container body 20 into the installation cavity 130, thereby achieving a concealing effect.

[0068] Moreover, since there is an air layer inside the bottom cover side wall 110 and it has a certain thickness, compared with a single thin wall, the gap between the bottom cover side wall 110 and the heating plate 30 also moves toward the bottom center of the glass container body 20. If the user observes the glass container body 20 downward from the outside of the liquid heating device, it is not easy to see the gap between the bottom cover side wall 110 and the heating plate 30 at an inclined downward perspective. Even if the user sees it, it is likely that the user will see the outer wall of the heating plate 30 and will not completely pass through the gap, further reducing the probability of the user seeing the inside of the installation cavity 130.

[0069] Moreover, in the current situation where liquid heating devices are diversified and container bodies are diversified, container bodies of different shapes need to be equipped with heating plates of different sizes to close the opening, which increases the production cost. If a large-sized container body is also equipped with a smaller-sized heating plate, it is necessary to increase the length of the connecting rib extending inward, but this will increase the gap between the bottom cover side wall of the single-layer thin-walled container bottom cover and the heating plate. If the container body is a glass container body, it will increase the probability that the user can see the inside of the installation cavity through the connecting rib. In this embodiment, an integrated container bottom cover 10 with double-layer side walls is used to support the glass container body 20, and the thicker bottom cover side wall 110 is used to block the connecting rib 210 from below, which can solve this problem. It is only necessary to design the container bottom cover 10 to match the size of the glass container body 20, without changing the size of the heating plate 30. This can improve the versatility of the heating plate 30 and save costs.

[0070] In specific applications, the diameter of the mounting cavity 130 in the container bottom cover 10 can be adjusted according to the actual size of the heating plate 30 to adapt it. There is no need to develop a new heating plate 30 according to the appearance, which facilitates the standardization of the heating plate 30.

[0071] Furthermore, the horizontal gap width between the bottom cover sidewall 110 and the heating plate 30 ranges from 0.5mm to 1mm. This prevents the bottom cover sidewall 110 from overheating or even melting due to a small gap between the two. Furthermore, it prevents the user from easily seeing into the mounting cavity 130 through the gap between the bottom cover sidewall 110 and the heating plate 30 due to a large gap between the two. The gap between the bottom cover sidewall 110 and the heating plate 30 can be minimized without causing the bottom cover sidewall 110 to overheat, thereby preventing the user from seeing into the mounting cavity 130 through the gap.

[0072] To improve the concealment effect, in some embodiments, a gap is provided between the heating plate 30 and the bottom cover sidewall 110 in the horizontal direction. The gap overlaps with the projection of the bottom cover sidewall 110 facing the inside of the installation cavity in the horizontal plane.

[0073] Here, the surface of the bottom cover side wall 110 facing the inner side of the installation cavity can be inclined and extended to just below the gap, for example Figure 2 and Figure 3 The inner sidewall 112 of the bottom cover can be extended at an angle, or a shielding rib can be provided on the surface of the bottom cover sidewall 110 facing the inside of the mounting cavity 130. The shielding rib can be extended to directly below the gap, so that the projection of the gap on the horizontal plane can fall on the surface of the bottom cover sidewall 110 facing the inside of the mounting cavity. In this way, even if the user sees the gap, even through the gap, what they see is the surface of the bottom cover sidewall 110 facing the inside of the mounting cavity 130 or the shielding rib, and the texture of the bottom cover sidewall 110 is improved, which improves the aesthetics.

[0074] Furthermore, in some embodiments, Figure 2 、 Figure 4 and Figure 6 As shown, the liquid heating device further includes a thermostat 40 disposed within the mounting cavity 130 of the container bottom cover 10. The thermostat 40 is screwed to the heating plate 30. The thermostat 40 is also screwed to the bottom cover bottom wall 120 of the container bottom cover 10. Here, the thermostat 40 is simultaneously fixed to the heating plate 30 and the bottom cover bottom wall 120, providing a secure installation. Furthermore, compared to directly attaching the thermostat 40 to the bottom cover side wall 110 of the container bottom cover 10, this does not affect the structural strength of the bottom cover side wall 110, thereby facilitating the stable support of the bottom cover side wall 110 for the glass container body 20.

[0075] As an example, Figure 2 、 Figure 4 and Figure 5As shown, the first screw 420 passes through the mounting hole 121 on the bottom wall 120 of the bottom cover and is inserted into the thermostat 40, thereby connecting the bottom wall 120 of the bottom cover and the thermostat 40. The second screw 430 passes through the thermostat 40 and is inserted into the heating plate 30, thereby connecting the thermostat 40 and the heating plate 30 firmly.

[0076] Furthermore, in some embodiments, Figure 2 and Figure 5 As shown, the liquid heating device also includes an upper power coupler 410, which is arranged at the bottom of the thermostat 40, and an avoidance hole 122 is provided on the bottom wall 120 of the bottom cover corresponding to the position of the thermostat 40 to allow the upper power coupler 410 to be exposed; the liquid heating device also includes a power base (not shown in the figure), and the container bottom cover 10 can be detachably placed on the power base, and the power base is used to support the container bottom cover 10, and a lower power coupler (not shown in the figure) is provided on the power base, and the lower power coupler is adapted to the upper power coupler 410.

[0077] In these embodiments, the liquid heating device also includes a power base, and the container bottom cover 10 can be detachably placed on the power base, and the heating plate 30 and the temperature controller 40 are powered by the upper power coupler 410 and the lower power coupler, so that the user can lift the glass container body 20 separately to perform water pouring operations or water collection operations, which is convenient to use.

[0078] Furthermore, in some embodiments, Figure 2 and Figure 3 As shown, the connecting rib 210 extends from the edge of the opening toward the interior of the container body and then downwardly, and the heating plate 30 is connected to the downwardly extending portion of the connecting rib 210 so that the bottom cover side wall 110 is disposed around the outer periphery of the heating plate 30 .

[0079] Here, the heating plate 30 is connected to the downward extending portion of the connecting rib 210, which is convenient for connection and helps to sink the heating plate 30 into the mounting cavity 130, so that the top of the container bottom cover 10 can also circumferentially surround the heating plate 30, increasing the depth of the gap between the two, thereby reducing the probability of the user viewing the periphery of the heating plate 30 and the interior of the mounting cavity 130 through the connecting rib 210.

[0080] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
