Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. A cooking appliance 100 according to the present invention will be described in detail with reference to fig. 1 to 10.

The utility model provides a cooking utensil 100. According to the utility model discloses a cooking utensil 100 can be electric rice cooker, electric pressure cooker or other cooking utensil, and cooking utensil 100 except having the function of cooking rice, can also have various functions such as cooking congee, a kind of deep pot hot water.

As shown in fig. 1 and 2, the cooking appliance 100 mainly includes a pot body 110, a lid 120, and an electromagnetic heating assembly 130. The lid 120 is openably and closably disposed on the pot body 110. The pot body 110 is substantially in a rounded rectangular parallelepiped shape, and has a receiving portion in a cylindrical shape, for example. The pot body 110 is provided therein with an inner pot 111 and a control plate assembly (not shown). The inner pot 111 may be made of a magnetically conductive material. The control panel assembly may be used to control a cooking program. The electromagnetic heating assembly 130 is disposed in the pot body 110 below the inner pot 111 to heat the food material in the inner pot 111. The inner pot 111 may be configured to be freely put into or taken out of the receiving part to facilitate cleaning of the inner pot 111, or may be configured to be fixed to the pot body 110. The inner pot 111 is used to contain food materials to be heated, such as rice, soup, etc. When the cover 120 is covered on the pot body 110, a cooking space can be formed between the cover 120 and the inner pot 111.

As shown in fig. 3 and 4, the electromagnetic heating assembly 130 mainly includes a coil panel 131, a lower magnetic strip holder 133, and a temperature sensing assembly 132. The coil disk 131 has a first through hole 131 a. The first through hole 131a may be located at the bottom center of the coil disk 131, and may be configured as a circular through hole. The lower rack 133 is disposed at the bottom of the coil disk 131 and has a second through hole 133 a. The lower magnetic stripe shelf 133 is used for mounting the magnetic stripe 144. The second through hole 133a corresponds to the first through hole 131a in position and shape. The temperature sensing member 132 extends through the first and second through holes 131a and 133a and serves to abut against the inner pot 111. Specifically, the temperature sensing assembly 132 is movable in a vertical direction. The top surface of the temperature sensing assembly 132 may abut against the bottom surface of the inner pan 111 for measuring the temperature of the inner pan 111.

In the present invention, in order to prevent the coil panel 131 from having a risk of melting glue due to an excessively high temperature in the area contacting the temperature sensing element 132, the electromagnetic heating element 130 further includes a heat insulating element 134. As shown in fig. 4 and 6, the heat insulator 134 is disposed on the circumferential outer side of the temperature sensing unit 132. One end (e.g., the bottom end) of the temperature sensing element 132 is confined between the coil disc 131 and the lower magnetic strip holder 133 to space the coil disc 131 and the temperature sensing element 132 apart. This will be explained in detail below.

As shown in fig. 7, the temperature sensing assembly 132 may include a body 136, a temperature sensing cap 135, and a temperature sensing element 137. The main body 136 may be made of a resin material. The body 136 is used to mount the temperature sensing element 137. The temperature-sensing element 137 may be an NTC temperature-sensing element, such as an NTC temperature sensor. The temperature sensing cap 135 covers the upper outside of the body 136 to be able to completely cover the temperature sensing element 137, and the temperature sensing element 137 may abut against the temperature sensing cap 135. The temperature sensing cap 135 is generally made of a high temperature resistant metal material, such as an aluminum alloy. Specifically, in the present embodiment, the heat insulator 134 is provided on the circumferential outer side of the temperature sensing cap 135 to space the coil disc 131 and the temperature sensing cap 135 apart.

Preferably, the thermal shield 134 is made of a non-magnetically conductive metallic material. The thermal conductivity of the material constituting the thermal insulator 134 is lower than that of the material constituting the temperature sensing cap 135. Thereby, the temperature of the region of the coil disk 131 close to the temperature sensing element 132 (specifically, the temperature sensing cap 135) is reduced so that the temperature of the region is not excessively high. More preferably, the heat resistance of the material constituting the heat insulator 134 is superior to that of the material constituting the coil disk 131. Optionally, the thermal shield 134 is made of stainless steel (e.g., 304 stainless steel) or a titanium alloy. Thus, by using common metal materials to manufacture the thermal insulation member 134, not only is processing facilitated, but also the production cost is reduced.

As shown in fig. 6, in the present embodiment, the heat insulating member 134 may include a first extension 134a, a second extension 134b extending upward from the first extension 134a, a third extension 134c extending inward from the second extension 134b (i.e., extending toward the center of the heat insulating member 134), and a fourth extension 134d extending downward from the third extension 134c, wherein the first extension 134a is caught between the coil disc 131 and the lower magnetic stripe frame 133. Specifically, the first and third extensions 134a and 134c may extend in a substantially horizontal direction to facilitate installation of the heat insulator 134. The second and fourth extension portions 134b and 134d may extend substantially in a vertical direction. The lower section of the second extension 134b may abut against the coil disk 131, so that the installation of the heat insulator 134 is robust.

The body 136 of the temperature sensing assembly 132 has a guide portion 136a protruding radially outward with respect to the temperature sensing cap 135, and the guide portion 136a is located below with respect to the heat insulator 134. The outer surface of the guide 136a is inclined with respect to the vertical direction to facilitate the installation of the temperature sensing assembly 132. As shown in fig. 6 and 7, it is preferable that a distance B in the vertical direction between the bottom surface of the first extension 134a and the bottom surface of the fourth extension 134d is smaller than a height C in the vertical direction of the guide 136 a. Therefore, when the top surface of the guide portion 136a of the main body 136 of the temperature sensing assembly 132 abuts against the bottom surface of the fourth extension portion 134d of the heat insulating member 134, the bottom surface of the guide portion 136a is lower than the top surface of the lower magnetic stripe frame 133, so as to prevent the bottom surface of the guide portion 136a from being clamped to the top surface of the lower magnetic stripe frame 133, and prevent the temperature sensing assembly 132 from moving unevenly.

As shown in fig. 8, the outer peripheral edge of the first extension portion 134a is provided with a notch 134 e. The notch 134e may be configured in a semicircular shape. As shown in fig. 10, correspondingly, the coil disk 131 has a projection 131 b. The protrusion 131b may be configured to extend in a direction toward the center of the first through hole 131 a. The shape of the protrusion 131b may correspond to the shape of the notch 134 e. The protrusion 131b is at least partially inserted into the notch 134e to position the heat insulator 134 to prevent the heat insulator 134 from rotating relative to the coil disk 131.

Further, as shown in fig. 9, the lower magnetic stripe frame 133 may have a notch 133 b. The shape of notch 133b may be the same as or similar to the shape of notch 134 e. The protrusion 131b is at least partially inserted into the notch 133b to position the lower rack 133 to prevent the lower rack 133 from rotating relative to the coil disk 131.

As shown in fig. 3 and 4, the electromagnetic heating assembly 130 may further include a side magnetic stripe frame 143 disposed at the bottom of the coil disk 131. The side bar holders 143 are disposed outside the lower bar holder 133 and extend in a radial direction of the coil disk 131. Fig. 3 and 4 exemplarily show that four side magnetic stripe frames 143 are arranged at equal angles at intervals outside the lower magnetic stripe frame 133. One magnetic strip 145 is mounted in each side magnetic strip holder 143. The side bar holders 143 may be mounted on the coil disk 131 by fasteners.

The electromagnetic heating assembly 130 may further include a coil 142, the coil 142 being circumferentially disposed on a bottom surface of the coil disc 131. For example, a plurality of snaps 147 may be provided on the coil disk 131 for securing the coil 142. The coil 142 can heat the food in the inner pot 111 after being energized. The magnetic strips 144 and 145 may be made of a manganese zinc ferrite material to perform an effect of gathering magnetic lines of force, thereby effectively preventing magnetic leakage and further improving the heating efficiency of the coil 142.

As shown in fig. 4 and 6, the electromagnetic heating assembly 130 may further include a cover plate 141 disposed at the bottom of the lower magnetic stripe frame 133. The cover plate 141, the lower magnetic stripe frame 133 and the heat insulator 134 may be fixed to the coil disk 131 by fasteners extending through the cover plate 141 and the lower magnetic stripe frame 133 and screwed to the coil disk 131. The cover plate 141 is used for limiting the temperature sensing assembly 132 to prevent the temperature sensing assembly 132 from withdrawing from the first through hole 131a and the second through hole 133 a.

The electromagnetic heating assembly 130 may further include an elastic member 146. The elastic member 146 is disposed between the cover plate 141 and the temperature sensing assembly 132. The elastic member 146 may be a compression spring to apply an upward elastic force to the temperature sensing element 132 so that the temperature sensing element 132 can abut against the inner pot 111 when the inner pot 111 is placed in the pot body 110.
