Problems solved by technology

[0002] Existing utensils, such as cups, generally need to be placed on a heating source (such as an induction cooker) for heating, or the heating layer is installed at the bottom of the cup. This heating method has the following disadvantages: (1) because the cup The heated part of the body or the part of the heating layer is directly exposed, and its heat (heated by the high-frequency changing magnetic field) is easily lost to the air (the heat is easily lost quickly to the bottom and around), and the heating efficiency is low, which affects the heating effect and causes energy waste. ; and the temperature at the bottom of the cup is high, which is easy to burn the human body (such as: hands); (2) the cup does not have the function of heat preservation (the temperature in the cup maintains the set value), such as: when the cup is used to store tea, the tea is cold The aftertaste is poor, resulting in waste of tea and water

Embodiment 1

[0026] Embodiment one: if figure 1 As shown, a double-layer induction heating vessel, this embodiment takes a teacup as an example: a teacup, including an inner layer 1 and an outer layer 2, the outer layer 2 is made of glass material, and the outer layer 2 is provided with an outer layer The bottom layer 21 is sealed, and a vacuum chamber 4 is provided between the outer layer 2 and the inner layer 1, wherein the inner layer 1 includes a glass side wall 11, and an induction heating bottom wall 3 arranged at the bottom opening of the glass side wall 11, namely: The glass side wall 11 and the induction heating bottom wall 3 enclose the inner layer 1, the bottom end 21 of the outer layer 2 is lower than the induction heating bottom wall 3 of the inner layer 1, and the bottom end 21 of the outer layer 2 The vertical height difference h between the bottom surface A of the induction heating bottom wall 3 of the inner layer 1 is between 0.1mm-50mm; in this embodiment, the induction h...

Embodiment 2

[0029] Embodiment two: if figure 2 As shown, this embodiment is also a double-layer induction heating vessel, and its structure is similar to that of the above-mentioned embodiment 1, the difference is that: the inner induction heating bottom wall 3 includes a closed bottom layer 32 and a metal heating layer 31, The airtight bottom layer 32 is a non-metal heat-conducting material layer, including a glass, pottery or other non-metal heat-conducting material. The metal heating layer 31 is fixed on the lower surface of the airtight bottom layer 32. The metal coating on the lower surface of the bottom layer 32.

[0030] Working principle: this embodiment is similar to the working principle of embodiment 1, the difference is: after the metal heating layer 33 generates heat, the heat is transmitted to the inner layer 1 through the airtight bottom layer 32, which can also achieve the effect of this patent.

Embodiment 3

[0031] Embodiment three: as image 3 As shown, this embodiment is also a double-layer induction heating vessel, and its structure is similar to the above-mentioned embodiment two, the difference is: the metal heating layer 31 is fixed on the upper surface of the airtight bottom layer 32, and the metal heating layer here is The layer 31 may be a metal coating on the upper surface of the airtight bottom layer 32 , and the airtight bottom layer 32 is the bottommost surface A of the bottom wall 3 for induction heating.

Abstract

The invention discloses a double-layer induction heating vessel, comprising an inner layer and an outer layer and characterized in that the inner layer is provided with an induction heating bottom wall, and the bottommost end of the outer layer is lower than the induction heating bottom wall of the inner layer. The double-layer induction heating vessel has the advantages that the induction heatingbottom wall and a heating source are spaced by a certain distance, the induction heating bottom wall is avoided directly contacting the heating source, vessel bottom heating is centralized to the induction heating bottom wall of the inner layer, and therefore, direct exposure of the induction heating bottom wall is avoided, heat loss is effectively decreased, heating effect is improved, and energy is saved; in addition, the bottom end of the outer layer has low temperature, so that scalding is effectively avoided; further, the induction heating bottom wall and the heating source are spaced bythe certain distance, the heating source is assisted in controlling the heating (temperature) of a cup, and vessel heat preservation is achieved; for example, a teacup having an insulation function can keep tea temperature and maintain drinking taste; therefore, the defect is avoided that the need for dumping due to low temperature and poor tea taste leads to waste; in addition, the whole vesselis simple and reasonable in structure.
