Description

Technical Field

[0001] The utility model relates to the field of electromagnetic cookers, in particular to a four-point temperature measurement electromagnetic cooker. Background Art

[0002] The prior art has built-in induction cookers, that is, the induction cooker can be embedded in a desktop, a stove, or other equipment.

[0003] In the prior art, induction cookers are generally provided with a temperature measuring element for detecting the temperature of the induction cooker. The temperature measuring element is generally arranged under the panel. When the temperature is detected to be too high, the PCB controller controls the induction cooker to cut off the power, thereby avoiding accidents caused by the induction cooker being too high in temperature. However, in the prior art, only one temperature measuring element is arranged, which may cause the problem of being unable to detect the local high temperature of the induction cooker.

[0004] Therefore, a four-point temperature measurement induction cooker is proposed to solve the above technical problems. Utility Model Content

[0027] Reference Figures 1 to 4 , a four-point temperature measurement induction cooker, comprising:

[0028] A four-point temperature measurement induction cooker includes a bottom shell 1, a panel 2 is provided on the top of the bottom shell 1, a heating part 3 and a PCB board 6 are provided inside the bottom shell 1, a first temperature measuring element 31 is provided inside the heating part 3, a second temperature measuring element 4 is fixedly installed at the bottom of the panel 2, a third temperature measuring element 5 is fixedly installed in the bottom shell 1, and the third temperature measuring element 5 is a non-contact temperature sensor; and a fourth temperature measuring element 61 is fixedly installed on the PCB board 6. The first temperature measuring element 31, the second temperature measuring element 4, the third temperature measuring element 5, and the fourth temperature measuring element 61 are all electrically connected to the PCB board 6, which is an electrical connection method that can be selected by those skilled in the art, and will not be repeated here.

[0029] As a preferred embodiment, the third temperature measuring component 5 is fixedly installed at the bottom of the panel 2.

[0030] As a preferred embodiment, the heating part 3 includes a coil and a coil mounting frame, the first temperature measuring component 31 is fixed on the coil mounting frame and is tightly attached to the coil, the distance between the first temperature measuring component 31 and the panel 2 is 2-12mm, and the first temperature measuring component 31 is a non-ferrous thermistor.

[0031] As a preferred embodiment, the sensitive detection temperature range of the third temperature measuring component 5 includes a range of 120-270°C, and the upper limit of the sensitive detection temperature range of the third temperature measuring component 5 is higher than the upper limit of the sensitive detection temperature range of the first temperature measuring component 31, the second temperature measuring component 4, and the fourth temperature measuring component 61.

[0032] As a preferred embodiment, the first temperature measuring element 31 is an epoxy resin encapsulated thermistor, the third temperature measuring element 5 is an IR infrared temperature measuring element, and the second temperature measuring element 4 and the fourth temperature measuring element 61 are both bare thermistors. The response speed of the IR infrared temperature measuring element is in the millisecond level, while the response speed of the ordinary thermistor temperature measuring element is in the second level, and the life of the epoxy resin encapsulated thermistor is higher than that of the bare thermistor. The IR infrared temperature measuring element is used to measure the temperature of the pot body. Although the cost is relatively high, the temperature measurement is accurate and fast, and can well avoid dry burning and other situations; the cost of the epoxy resin encapsulated thermistor is not the lowest, but because the temperature of the coil is not low, the use of epoxy resin encapsulated thermistors can better balance the cost and product quality.

[0033] As a preferred embodiment, the PCB board 6 is used to control the power of the heating part 3 .

[0034] As a preferred embodiment, both sides of the bottom shell 1 are provided with limiting parts 7, and the limiting parts 7 include mounting seats 71, and the mounting seats 71 are fixedly mounted on the bottom shell 1, and spring pieces 72 are arranged on the mounting seats 71. When in use, a through hole is opened at a place where installation is required, such as a desktop, a stove, etc., and the bottom shell 1 is placed into the through hole. When the spring piece 72 passes through the through hole, the top of the spring piece 72 abuts against the installation place under the action of its own elastic force, thereby limiting the movement of the induction cooker in the up and down directions, ensuring the stable installation of the induction cooker; when the induction cooker needs to be disassembled, the spring piece 72 is pressed inwardly to make the top of the spring piece 72 shrink and pass through the through hole.

[0035] As a preferred embodiment, since the thickness of the installation parts such as desktops and stoves are inconsistent, if the thickness is thin, the top of the spring piece 72 cannot abut against it, conversely, if the thickness is thick, the top of the spring piece 72 cannot pass through the through hole. In order to solve this problem, a slider 75 is slidably installed on the mounting seat 71, and the spring piece 72 is fixed on the slider 75 by a bolt 73. The slider 75 is slid to adjust the height of the spring piece 72, and then it can be installed and used on desktops, stoves, etc. with different thicknesses.

[0036] As a preferred embodiment, a sliding hole 74 is provided on the mounting seat 71, and a slider 75 is slidably installed in the sliding hole 74. A screw rod 76 is rotatably installed in the sliding hole 74, and the screw rod 76 is threadedly connected with the slider 75. The screw rod 76 is rotated to drive the slider 75 to move up and down, so that the height of the spring piece 72 can be adjusted, and the operation is simple and convenient.

[0037] As a preferred embodiment, limit blocks 77 are fixedly installed on both sides of the sliding block 75, and limit holes 78 are opened on both sides of the sliding hole 74. The limit blocks 77 are slidably connected with the limit holes 78.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
