The embodiment provides an induction cooker, which aims to improve the measurement precision of the heating temperature of a cooker on the induction cooker, thereby improving the accuracy of temperature control and reducing heat loss. At present, when the induction cooker is used, a cooker is placed on a panel, and a magnetic field generated by a coil panel acts on the cooker to heat the cooker. Because the pan contacts with the panel, the heat that the pan produced transmits to the holding intracavity through the panel to by the temperature element detection of panel bottom, thereby confirm the real-time heating temperature of pan. Because the temperature of the cookware needs to pass through the panel, the temperature measuring process of the temperature measuring element has certain delay, and the heat transmitted by the panel has certain loss, thereby not only reducing the detection accuracy of the temperature measuring element, but also influencing the accuracy of the temperature control of the induction cooker; and causes the induction cooker to form larger heat loss, which affects the heating effect.

In order to solve the above technical problem, referring to fig. 1 to 7, the induction cooker provided in this embodiment includes a bottom case 10 and a panel 20 disposed on the bottom case 10, an accommodating cavity is defined between the bottom case 10 and the panel 20, and an electrically connected coil panel 11 and a control panel 12 are disposed in the accommodating cavity.

Referring to fig. 2 and 3, a coil panel 11 and a control panel 12 of the induction cooker are arranged in the accommodating cavity, and the coil panel 11 generates a magnetic field under the control of the control panel 12, and the magnetic field acts on the pot on the panel 20 and heats the pot. Wherein in order to guarantee the more high-efficient stable work of electromagnetism stove, the holding intracavity can also be provided with the fan 13 of cooling for the heat dissipation of each electronic component to and show electromagnetism stove operating condition's lamp plate 14. The fan 13 may be disposed at a ventilation opening of the bottom case 10, the ventilation opening may include an air inlet and an air outlet, and the air inlet and the air outlet may be disposed at the bottom and/or the side wall of the bottom case 10. The fan 13 located at the ventilation opening can drive low-temperature air flow outside the induction cooker to enter the accommodating cavity from the air inlet, and the low-temperature air flow carries heat around the electronic element after flowing through each electronic element (such as the coil panel 11 or the control panel 12), flows out from the air outlet, and carries the heat in the accommodating cavity to the outside. The lamp plate 14 can be located the position that the holding intracavity is close to panel 20, and the light that the pilot lamp on the lamp plate 14 sent is seen through by the lateral wall of panel 20 or drain pan 10 to the user looks over, in time knows the operating condition of electromagnetism stove.

In order to solve the problem of low temperature measurement accuracy of the temperature measurement element 30, the through hole 21 is formed in the panel 20, the through hole 21 is communicated with the outside and the accommodating cavity, the temperature measurement element 30 is located in the through hole 21, the temperature measurement end of the temperature measurement element 30 can extend out of the through hole 21, when a pot is placed on the panel 20, the temperature measurement end of the temperature measurement element 30 is directly contacted with the pot, and therefore any structure for isolating heat transfer between the pot and the temperature measurement element 30 is avoided.

Based on the communication between the through hole 21 and the accommodating cavity, the temperature measuring element 30 located in the through hole 21 can be electrically connected with the control board 12 in the accommodating cavity, and the electrical connection can mean that the two are connected through a wire or a wireless connection, so that the installation difficulty in the induction cooker is reduced. The shape and size of the through hole 21 can be set according to the shape and size of the temperature measuring element 30, as long as it is ensured that the temperature measuring element 30 can protrude through the through hole 21, which is not limited in this embodiment.

The temperature measuring element 30 provided in this embodiment may be a negative temperature coefficient thermistor NTC, and in other realizable implementations, the temperature measuring element 30 may also be a thermocouple, and the type of the temperature measuring element 30 is not limited in this embodiment.

Further, when the pot contacts the panel 20, a part of heat of the pot is transferred to the panel 20, which not only causes heat loss of the pot, increases heating energy consumption of the induction cooker, but also increases thermal impact of the panel 20, which causes cracking or deformation of the panel 20. In order to avoid the above situation, the panel 20 provided in this embodiment is further provided with the supporting member 40, the supporting member 40 can abut against the bottom of the cookware, so as to avoid direct contact between the cookware and the panel 20, and the distance between the panel 20 and the cookware is increased by using the height of the supporting member 40, thereby effectively relieving the heat transferred from the cookware to the panel 20, reducing the heating energy consumption of the induction cooker, and prolonging the service life of the panel 20.

Based on the fact that most of the existing panels 20 are made of blackcrystals, ceramics or glass, the thermal shock resistance effect is low, and in order to further ensure the use safety of the panels 20, the panels 20 provided by the embodiment can be selected from one or more of slate boards, granite boards, limestone boards, marble boards and artificial stone boards.

As a possible embodiment, the through hole 21 is located at the center of the projection area of the coil disk 11 on the panel 20.

It should be noted that, based on that the magnetic field generated by the coil panel 11 surrounds the plane of the coil panel 11, and the magnetic induction line of the magnetic field cuts the plane, the central position of the coil panel 11 is the region where the magnetic field converges, the through hole 21 for installing the temperature measuring element 30 is disposed on the panel 20, and corresponds to the central position of the coil panel 11, it can be ensured that the temperature measuring element 30 accurately measures the temperature of the pot corresponding to the central position of the coil panel 11, so as to obtain the effective pot temperature, so that the control board 12 accurately adjusts the heating power and the heating state of the coil panel 11 according to the temperature.

Further, in order to facilitate the installation of the supporting member 40, the panel 20 may be formed with an installation hole 22, and the supporting member 40 may be detachably disposed in the installation hole 22.

It should be noted that, because the supporting member 40 supports the pot, the stability of the supporting member 40 mounted on the panel 20 directly affects the supporting effect of the supporting member 40. In the embodiment, the supporting piece 40 is detachably arranged in the mounting hole 22, and the supporting piece 40 is fastened by the mounting hole 22, so that the supporting piece 40 is prevented from being displaced or falling off in the process of supporting the cookware. Specifically, the supporting member 40 may be disposed in the mounting hole 22 by one or more of a snap structure, a thread structure, an interference fit, etc., and the present embodiment is not limited to the above-mentioned example. The supporting member 40 is detachably disposed in the mounting hole 22, so that the difficulty in manufacturing the panel 20 is greatly reduced, the manufacturing efficiency of the induction cooker is improved, and the replacement and maintenance of the supporting member 40 are facilitated.

It should be noted that, because the supporting member 40 needs to support the pot and needs to have a higher connection strength with the panel 20, in this embodiment, the supporting member 40 is provided as the supporting section 41 and the embedding section 42 which are connected with each other, when the supporting member 40 is installed on the panel 20, as shown in fig. 4, the embedding section 42 of the supporting member 40 is located inside the installation hole 22, and the outer wall of the embedding section 42 is connected with the inner wall of the installation hole 22, so that the connection strength between the supporting member 40 and the panel 20 can be improved, and the problem that the supporting member 40 is displaced or falls off in the using process is avoided. This support piece 40's support section 41 is located the outside of mounting hole 22, supports the bottom of pan through exposing at the outside support section 41 support of mounting hole 22, plays the purpose of isolated panel 20 and pan to avoid the heat transfer of pan to panel 20, reduced the heat loss of pan on panel 20, and reduce the heat impact of panel 20, guarantee panel 20's stability in use.

The supporting member 40 may be made of a non-magnetic material, and the supporting member 40 is located on the panel 20 and located in a region covered by the magnetic field generated by the coil panel 11, so that in order to avoid the interaction between the magnetic field and the supporting member 40, the supporting agent may be made of a non-magnetic material, such as ceramic, high temperature resistant plastic, aluminum alloy, or copper. To ensure the mechanical strength of the supporting member 40 itself, the supporting section 41 and the embedding section 42 may be integrally formed.

Further, as shown in fig. 5 and 6, in order to improve the installation stability of the supporting member 40 on the panel 20, the cross-sectional area of the supporting section 41 may be set to be larger than that of the embedding section 42, when the supporting member 40 is disposed in the installation hole 22, the size of the embedding section 42 matches that of the installation hole 22, and the cross-sectional area of the supporting section 41 is larger than that of the installation hole 22, so that the supporting section 41 is clamped at the opening position of the installation hole 22, and further plays a role in fixing.

This ensures that the supporting member 40 can have a larger contact area with the mounting hole 22, thereby improving the stability of the connection, and also avoiding the influence on the mechanical strength of the panel 20 due to the excessive depth of the mounting hole 22. As an alternative embodiment, the panel 20 of the present induction cooker is generally 5-8mm thick, and the maximum depth of the mounting hole 22 may be 2-4 mm. In practical applications, the depth of the mounting hole 22 may be set according to the thickness of the panel 20, which is not limited in this embodiment.

In an embodiment, the outer wall of the insertion section 42 of the supporting member 40 is bonded to the inner wall of the mounting hole 22. Referring to fig. 4, the outer wall of the embedding section 42 of the supporting section 41 is connected with the inner wall of the mounting hole 22 by glue, and the adhered area may include the area between the side wall of the embedding section 42 and the side wall of the mounting hole 22, and the area between the bottom of the embedding section 42 and the bottom of the mounting hole 22. The thickness of the adhesive on the side wall can be a range shown in a in the figure, and a specific value range of a can be 0.1-0.5 mm. The thickness of the glue at the bottom may be in the range indicated by c in the figure, and the specific value range of c may likewise be 0.1-0.5 mm. Further, the value of the thickness c of the adhesive can be larger than the value of the thickness a of the adhesive, so that the problem that the aperture of the opening of the mounting hole 22 is too large can be avoided, and meanwhile, the bonding strength between the embedding section 42 and the mounting hole 22 can be ensured.
