Fig. 1 is a schematic structural diagram of a liquid heating container according to an embodiment of the present application, where the liquid heating container may include a kettle body assembly 10 and a base 20, and the kettle body assembly 10 and the base 20 are connected by an upper coupler and a lower coupler to heat a liquid in the kettle body assembly 10.

Fig. 2 is an exploded view of the kettle body assembly, and fig. 3 is a partial structure view of the bottom of the kettle body assembly. As shown in fig. 2 and 3, the kettle body assembly includes a kettle body 1, a heating plate 2, a heating pipe 3, a reflecting cover 4 and a heat insulation plate 5.

Wherein, kettle body 1 is used for holding liquid, and hot plate 2 sets up in the bottom of kettle body 1. The heating pipe 3 is arranged on one side of the heating plate 2 away from the kettle body 1, and the heating pipe 3 is used for heating the heating plate 2.

In a specific embodiment, the heating pipe 3 may be a carbon fiber heating pipe, and the heating pipe generates far infrared light to perform radiant heating after being electrified, the heating plate 2 may be a glass ceramic plate, and after heat is transferred to the heating plate 2, the liquid in the kettle body 1 is heated by the heating plate 2. When the carbon fiber heating pipe is normally heated, the temperature of the surface of the pipe is generally constant at 600-720 ℃, and the problem of high temperature caused by a high-temperature environment is much solved.

Fig. 4 is a cross-sectional view of the bottom of the kettle body in the liquid heating vessel according to the embodiment of the present application, and fig. 5 is a cross-sectional view of the structure of the bottom part of the kettle body.

As shown in fig. 4 and 5, the liquid heating container provided in the embodiment of the present application further includes a reflective cover 4, where the reflective cover 4 is disposed on a side of the heating plate 2 away from the kettle body 1, and the reflective cover 4 is connected to the kettle body 1, and reflects far infrared light generated by the heating pipe 3 by using the reflective cover 4. A receiving space H is formed between the reflecting cover 4 and the heating plate 2, and the heating tube 3 is located in the receiving space H. In a specific embodiment, the reflecting cover 4 is connected with the kettle body 1 through the supporting frame 7, and the reflecting cover 4 and the heating plate 2 can also form fixed connection through the structural design of the supporting frame 7. In the embodiment shown in fig. 5, the reflector 4 is connected to a flange of the support 7, which flange can also be connected to the heating plate 2 by means of a glue layer (not shown). The support 7 may then be attached to the kettle body 1 by means of a glass cement (not shown).

The embodiment of the application provides a liquid heating container further comprising an insulation board 5 arranged on one side of the reflecting cover 4 away from the heating plate 2. Through setting up heated board 5, can block the high temperature air current in the hood 4, prevent that heat from dispelling fast. The heat preservation plate 5 can also absorb and store heat, and the direction of high-temperature airflow to the bottom of the kettle is slowed down. Because the upper coupler and the inner lead are usually arranged in the bottom cover of the kettle bottom, the technical problems of melting and carbonization of the bottom cover, the upper coupler and the inner lead in the prior art are solved, and the service life of the liquid heating container is integrally prolonged.

The heat-insulating plate 5 may be fixed in various ways, and the heat-insulating plate 5 may be connected to the reflecting cover 4 by a fixing member, or may be supported and fixed by a heat-dissipating cover 6 as will be described later in the present embodiment.

In a specific embodiment, as shown in fig. 5, the side of the thermal insulation board 5 facing the reflection housing 4 is provided with an arc-shaped concave 511. The reflecting cover 4 is provided with an arc convex surface 41 on a side facing the heat insulation board 5, the accommodating space H is formed on a side facing the heating pipe 3 of the reflecting cover 4, and the position of the accommodating space H corresponds to the arc convex surface 41.

In this embodiment, the reflecting cover 4 has the arc-shaped convex surface 41 to form the accommodating space H, so that a space is left for installing the heating tube 3, and since the heating tube 3 has a generally annular structure, the reflecting cover 4 can form a circle of arc-shaped convex surfaces 41, and the middle part of the reflecting cover 4 can be closely attached to the heating plate 2.

As shown in fig. 4, a gap is formed between the arc concave 511 and the arc convex 41, thereby forming a certain distance between the reflecting cover 4 and the heat insulation board 5, and the existence of the distance can slow down the heat to directly flow to the heat insulation board 5, so that the time for the heat insulation board 5 to reach heat balance in the heating process is prolonged. That is, once the thermal insulation board 5 absorbs heat and then stores heat to reach heat balance, it does not absorb heat any more, and it tends to dissipate heat to the surroundings to continue heat balance. Therefore, the presence of this distance helps to slow the rate of heat transfer.

As shown in fig. 5, the gap between the arc concave surface 511 and the arc convex surface 41 is an unequal width gap, and the width dimension a of the gap at the narrowest point is 0.5mm < a <10mm. In the present embodiment, if the gap a is too small, the effect of slowing down the heat transfer is not achieved. If the gap a is too large, it occupies an installation space inside the liquid heating vessel, not taking advantage of the compactness of the structure. Preferably a is 2mm, at such a distance not only the transfer of heat can be slowed down, but also the internal part arrangement of the liquid heating vessel can be optimised.

Meanwhile, the gap at the widest part is positioned at one side of the kettle body, and the width dimension B of the gap at the widest part is 2.5mm < B <10mm. If the gap B is too small, the effect of slowing down the heat transfer may not be achieved. If the gap B is too large, it occupies an installation space inside the liquid heating vessel, not taking advantage of the compactness of the structure. Preferably B is 3.5mm, at such a distance not only the transfer of heat can be slowed down, but also the internal part arrangement of the liquid heating vessel can be optimised. Moreover, since the gap B is closer to the body 1, the body 1 is usually glass, and breakage of the body 1 due to an excessive temperature can be avoided at a proper distance.

Taking a liquid heating vessel with a capacity of 1.5L as an example, the time required to boil a kettle of water to boiling is 10-12 minutes, and the time required for the thermal insulation board 5 to reach thermal equilibrium is 3 minutes. Then, before the water is boiled to boil, the heat insulation board 5 is required to be in a heat absorption and heat storage process, and the heat cannot be balanced. After the water is boiled to boiling, the liquid heating container can be heated intermittently, and the heat preservation plate 5 stores heat to ensure that the water in the kettle is in a micro-boiling state or a heat preservation state continuously. Therefore, the above-described requirements can be satisfied by providing the thickness of the heat insulating plate 5.

As shown in fig. 5, the heat insulation board 5 includes a main body 51, and an arc concave 511 is formed on the main body 51, and the main body 51 is located opposite to the heating pipe. The thickness dimension C of the main body 51 is 5mm < C <32mm. If the thickness dimension C is too small, the heat-insulating board 5 stores too little heat, and the heat-insulating board 5 dissipates heat once it reaches thermal equilibrium. If the thickness dimension C is too large, more installation space is occupied. It is preferable that C is 24mm, and at such a distance, not only the heat storage capacity of the heat insulating plate 5 can be ensured, but also the internal part arrangement of the liquid heating vessel can be optimized.

As shown in fig. 4 and 5, in a specific embodiment, the liquid heating container further includes a heat dissipation cover 6, the heat dissipation cover 6 is disposed on a side of the heat insulation board 5 away from the reflective cover 4, and the heat dissipation cover 6 is connected to the kettle body 1, and the heat insulation board 5 is fixedly clamped between the reflective cover 4 and the heat dissipation cover 6.

In this embodiment, the heat dissipation cover 6 may be connected to the reflective cover 4 and the kettle body 1 through the supporting frame 7. The heat dissipation cover 6 plays a role in fixing and limiting the heat insulation board 5 and a role in heat dissipation. Before the heat preservation board 5 does not reach the heat balance, the heat dissipation cover 6 plays a role in fixing and limiting, and after the heat preservation board 5 reaches the heat balance, the heat dissipation cover 6 contacts with the heat preservation board 5, so that the heat dissipation effect can be played.

As shown in fig. 4, in a specific embodiment, the heat dissipation cover 6 includes a first heat dissipation portion 61 and a second heat dissipation portion 62. The first heat dissipation portion 61 is attached to the heat insulation board 5, and the second heat dissipation portion 62 is formed in a bent shape on the outer side of the first heat dissipation portion 61.

Referring to fig. 5 and 6, the first heat dissipation portion 61 is substantially U-shaped, and is capable of limiting the heat insulation board 5 therein. The second heat dissipation portion 62 may be integrally formed with the first heat dissipation portion 61, and formed outside the first heat dissipation portion 61. One part of the second heat dissipation part 62 is connected with the support frame 7, and the other part extends downwards along the height direction of the liquid heating container, and the arrangement of the second heat dissipation part 62 can further enhance the heat dissipation effect.

As shown in fig. 6, the liquid heating container further includes a bottom cover 8, and a receiving cavity is defined between the bottom cover 8, the heating plate 2 and the kettle body 1, and the heating pipe 3, the reflecting cover 4, the heat-insulating plate 5 and the heat-dissipating cover 6 are all disposed in the receiving cavity.

The first heat sink 61 includes a first portion 611 extending in the height direction of the bottom cover 8, and the first portion 611 is attached to the thermal insulation board 5 near the outer side of the bottom cover 8 in the circumferential direction. The distance D between the outer side surface of the first portion 611 and the inner side surface of the bottom cover 8 is 5mm < D <30mm. If this distance D is too small, heat is easily transferred to the kettle body 1, causing a problem of breakage of the kettle body 1. If D is too large, it may result in an excessive overall size of the kettle body 1, and a smaller overall size of the heat dissipation cover 6, and accordingly the size of the heat insulation board 5 engaged therewith may be affected. In order to achieve both the heat transfer rate and the installation space of the liquid heating vessel, it is preferable that the distance D between the outer side surface of the first portion 611 and the inner side surface of the bottom cover 8 is 12mm in size.

On the basis of the above embodiment, the first heat sink 61 includes the second portion 612 connected to the first portion 611, the second portion 612 being located on a side of the first portion 611 away from the side wall of the bottom cover 8, the second portion 612 extending in the radial direction of the bottom cover 8.

The provision of the second portion 612 provides convenience in restricting the position of the thermal insulation board 5 and can function as a support for the thermal insulation board 5.

On the basis of the above embodiment, the first heat sink 61 includes the third portion 613 and the fourth portion 614. Wherein the third portion 613 and the fourth portion 614 are each located at a side of the second portion 612 remote from the side wall of the bottom cover 8. Wherein the fourth portion 614 extends in a radial direction of the bottom cover 8, and the third portion 613 is located between the second portion 612 and the fourth portion 614. The fourth portion 614 is higher than the second portion 612 in the height direction of the bottom cover 8.

In the above-described structure, the heat sink housing 6 may be connected to the reflection housing 4 at the position of the fourth portion 614 by the connection member. Because the fourth portion 614 is higher than the second portion 612, space is reserved for mounting the upper coupler 9, and a certain distance is reserved between the heat dissipation cover 6 and the upper coupler 9, so that heat is prevented from being transferred to the upper coupler 9 too quickly, and the upper coupler 9 is prevented from being fused.

As described above, the liquid heating vessel further comprises an upper coupler 9 mounted to the bottom cover 8. The position of the upper coupler 9 corresponds to the fourth portion 614, and the distance E between the highest point of the upper coupler 9 and the bottom surface of the fourth portion 614 in the height direction of the bottom cover 8 is 5mm < E <30mm.

In this embodiment, if the distance E between the highest point of the upper coupler 9 and the bottom surface of the fourth portion 614 is too small, heat is transferred to the upper coupler 9 too quickly to melt the upper coupler 9, and if the distance E between the highest point of the upper coupler 9 and the bottom surface of the fourth portion 614 is too large, more installation space is occupied. In order to compromise the distance and spatial arrangement of the heat transfer, it is preferable that D be 18mm.

The liquid heating container provided by the embodiment of the application can ensure that heat can not excessively dissipate in the heating process, and the stored heat is utilized to maintain a micro-boiling or heat-preserving state, so that the power consumption and the energy efficiency of the liquid heating container are improved. The heating device can perform full-power heating in the normal heating process, shortens the heating time and reduces the waiting time of users.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
