Description

Technical Field

[0001] This invention relates to an electric rice cooker. Background Technology

[0002] The existing technology, Chinese patent 201720986463.9, describes an electric cooker, whose structure includes a pot body (1), a lid (2), and a temperature sensor thermocouple (4). The lid (2) is detachably mounted on the top of the pot body (1). The bottom of the pot body (1) is 10cm thick, and a groove (3) is provided in the center of the bottom of the pot body (1). The groove (3) is circular with a depth of 1cm and a diameter of 3cm, and the temperature sensor thermocouple (4) is embedded in the groove (3). The advantages of this invention are: simple and effective structure, thickened bottom of the pot body, and groove. After being placed in the heating area, the temperature sensor thermocouple can fit into the groove at the bottom of the pot body, effectively collecting the temperature inside the pot body, thereby achieving more precise heating control of the pot body, ensuring the stable quality of cooked food such as rice, and helping to improve heating efficiency and reduce energy consumption. The problem is: it cannot reflect the temperature of the pot body 1. Summary of the Invention

[0003] The purpose of this invention is to provide an electric cooker with an improved temperature probe setting, which accurately reflects the temperature inside the inner pot.

[0004] This invention is implemented as follows: an electric cooker with an improved temperature probe setting, characterized in that it includes a pot shell with an upper opening, an inner pot, an electric heating plate, a pot lid with a lower opening, and a temperature probe inside the pot. The upper part of the inner liner is provided with an annular step, and the annular step is provided with mounting holes; The electric heating plate is fixed to the bottom plate of the inner pot, which is located inside the pot shell. The temperature probe inside the pot is fixed to the mounting hole and extends into the inner pot. The pot lid is fitted with an annular step support, and the temperature probe inside the pot extends into the pot lid.

[0005] Preferably, it also includes a sealing ring, which is disposed on the temperature probe inside the pot and fits against the annular step.

[0006] Preferably, it also includes an I-beam seal, which comprises a pipe body, an upper flange, and a lower flange. The tube body fits into the mounting hole, and the upper and lower flanges are respectively attached to the upper and lower surfaces of the annular step. The temperature probe inside the pot passes through the tube body.

[0007] Preferably, it also includes a heating plate temperature probe, which is located on the electric heating plate.

[0008] Preferably, the upper opening of the inner liner is provided with an annular flange with a right-angle cross-section, and the axial cylindrical part of the annular flange and the outer surface of the inner liner form an insertion groove. The upper end of the pot shell is provided with an annular interface, which is inserted into the insertion slot, and the upper end of the pot shell supports the axial cylindrical part.

[0009] This invention relates to an electric cooker with an improved temperature probe setting. Due to this structure, the temperature sensor head of the internal temperature probe is located inside the inner pot, which can accurately reflect the temperature inside the inner pot, making it convenient to control and improving heating efficiency.

[0015] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] like Figure 1 As shown, an electric cooker with an improved temperature probe setting includes a pot shell 1 with an upper opening, an inner pot 2, an electric heating plate 3, a pot lid 4 with a lower opening, and a temperature probe 5 inside the pot. The inner liner 2 has an annular step 21 on its upper part, and an installation hole 22 is provided on the annular step 21. The electric heating plate 3 is fixed to the bottom plate of the inner pot 2, which is located inside the pot shell 1. The pot temperature probe 5 is fixed to the mounting hole 22 and extends into the inner pot 2. The pot lid 4 is fastened to the inner pot 2. With this design, the pot temperature probe 5 can reflect the temperature of the inner pot 2, which is convenient for control and improves heating efficiency.

[0018] As a further improvement of the present invention, it also includes a sealing ring 6, which is disposed on the temperature probe 5 inside the pot and fits against the annular step 21.

[0019] This invention can also be implemented as follows: Figure 3 As shown, it also includes an I-shaped seal 7, which comprises a pipe body 71, an upper flange 72, and a lower flange 73. The tube body 71 is fitted with the mounting hole 22, the upper flange 72 and the lower flange 73 are respectively attached to the upper and lower surfaces of the annular step 21, and the pot temperature probe 5 passes through the tube body 71.

[0020] As a further improvement of the present invention, it also includes a heating plate temperature probe (not shown in the figure), which is mounted on the electric heating plate 3. The temperature of the electric heating plate 3 reflects the temperature inside the inner liner 2, and can also prevent dry burning.

[0021] The inner liner 2 has an annular flange 23 with a right-angle cross section on its upper opening. The axial cylindrical part 231 of the annular flange 23 and the outer surface of the inner liner 2 form an insertion groove.
