[0028] See also Figure 1 , Figure 1 A structural schematic diagram of a cooking device 100 in an embodiment of the present application is shown. A cooking device 100 is provided in an embodiment of the present application. In this embodiment, the cooking device 100 is taken as an all-in-one steam-bake machine as an example. In other embodiments, the cooking device 100 can also be a steamer, an oven, etc.
[0029] like Figure 1 As shown, the cooking device 100 includes an inner pot 110, and a cooking cavity 111 is provided inside the inner pot 110. Figure 3 As shown, the inner liner 110 includes a side wall 112 with a temperature measuring hole 1121, the side wall 112 is any peripheral wall of the inner liner 110, and the side wall 112 is protruding with a connecting column 113, and the connecting column 113 is spaced apart from the temperature measuring hole 1121. Exemplarily, the connecting column 113 is welded to the side wall 112.
[0030] like Figure 2 and Figure 3 As shown, the cooking device 100 further includes a temperature measuring component 120, which includes a temperature measuring tube 121 and a connecting piece 122 sleeved on the outer periphery of the temperature measuring tube 121. In this embodiment, the connecting piece 122 is fixedly connected to the outer periphery of the temperature measuring tube 121. In this embodiment, the connecting piece 122 is a connecting flange, which is made of a conductive material, such as a metal part. The temperature measuring tube 121 is detachably connected to the inner pot 110 and passes through the temperature measuring hole 1121 to partially extend into the cooking cavity 111 to detect the temperature in the cooking cavity 111. Figure 3 As shown, the connecting piece 122 is provided with a connecting hole 1221 for connecting the connecting column 113 . When the temperature measuring tube 121 partially extends into the cooking cavity 111 , the connecting column 113 passes through the connecting hole 1221 to fix the temperature measuring assembly 120 .
[0031] like Figure 3 As shown, the cooking device 100 further includes an elastic member 130, which is sleeved on the outer periphery of the connecting column 113, and the two ends of the elastic member 130 are respectively in contact with the connecting piece 122 and the side wall 112, and the elastic member 130 is made of a conductive material so that the elastic member 130 can stably contact the connecting piece 122 and the side wall 112, thereby realizing that the connecting piece 122 of the temperature measuring component 120 is conductively connected to the side wall 112, and the temperature measuring tube 121 is grounded. In this embodiment, the elastic member 130 is a spring washer, and in other embodiments, the elastic member 130 can also be a spring, etc.
[0032] like Figure 2 and Figure 3 As shown, in one embodiment, the cooking device 100 further includes a sealing member 140, which is sleeved on the outer periphery of the temperature measuring tube 121, and the sealing member 140 is clamped between the connecting piece 122 and the side wall 112, so as to seal the connection between the temperature measuring tube 121 and the temperature measuring hole 1121 through the sealing member 140, thereby preventing air leakage from the gap between the temperature measuring hole 1121 and the temperature measuring tube 121. The sealing member 140 is used for sealing, and in this embodiment, the sealing member 140 is made of a material that can be deformed when subjected to force, such as a rubber material.
[0033] In one embodiment, the seal 140 is sealed to the temperature measuring tube 121, so that when the cooking device 100 is in the steaming function, there is a large amount of water vapor in the cooking cavity 111, and the seal between the seal 140 and the temperature measuring tube 121 is sealed to prevent water leakage and air leakage.
[0034] like Figure 4As shown, in one embodiment, the sealing member 140 is provided with a sealing hole 141 coaxial with the temperature measuring tube 121, and the sealing hole 141 is interference fit with the temperature measuring tube 121. In other embodiments, a sealing ring may be provided between the outer periphery of the temperature measuring tube 121 and the inner wall of the sealing hole 141 to achieve a sealed connection between the sealing member 140 and the temperature measuring tube 121.
[0035] In one embodiment, the end surface of the sealing member 140 facing the side wall 112 is a sealing end surface 146. Figure 4 As shown, the sealing end face 146 is provided with a convex ring 142, which is arranged around the sealing hole 141, so that when the sealing end face 146 is attached to the side wall 112, the convex ring 142 can abut against the side wall 112, thereby achieving the effect of sealing the sealing hole 141. In this embodiment, the sealing hole 141 is a flanged hole, and the convex ring 142 is formed by flanging the sealing hole 141.
[0036] like Figure 4 As shown, in one embodiment, the seal 140 includes a first sealing rib 143, which protrudes from the end face of the seal 140 facing the side wall 112, that is, the first sealing rib 143 protrudes from the sealing end face 146, and the first sealing rib 143 is an annular structure surrounding the sealing hole 141, so that when the sealing end face 146 is attached to the side wall 112, the first sealing rib 143 can abut against the side wall 112, thereby achieving the effect of further sealing the sealing hole 141.
[0037] like Figure 4 As shown, in one embodiment, the seal 140 includes a second sealing rib 144, and the second sealing rib 144 protrudes from the end face of the seal 140 facing the side wall 112, that is, the second sealing rib 144 protrudes from the sealing end face 146, and the second sealing rib 144 is an annular structure and is arranged along the edge of the seal 140, so that when the sealing end face 146 is in contact with the side wall 112, the second sealing rib 144 can abut against the side wall 112, so that the edges of the seal 140 are in contact with the side wall 112, further improving the sealing effect of the seal 140.
[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the sealing member 140 is provided with a through hole 145, and the elastic member 130 and the connecting column 113 both pass through the through hole 145. After the connecting column 113 passes through the through hole 145, it passes through the connecting hole 1221 of the connecting sheet 122 and is fixed. The elastic member 130 passes through the through hole 145 with its two ends respectively abutting against the side wall 112 and the connecting sheet 122.
[0039] like Figure 3As shown, in one embodiment, the through hole 145 is coaxially arranged with the connecting column 113, and the aperture of the through hole 145 is larger than the diameter of the elastic member 130. For example, the aperture of the through hole 145 is at least 1 mm larger than the diameter of the elastic member 130, so that the sealing member 140 does not interfere with the elastic deformation of the elastic member 130, so that the elastic member 130 maintains a stable connection with the side wall 112 and the connecting piece 122. At the same time, the thickness of the sealing member 140 is not greater than the original length of the elastic member 130 (the natural length when no force is applied). For example, the thickness of the sealing member 140 is 1.5 mm-2 mm, so as to avoid the sealing member 140 being too thick, resulting in the elastic member 130 not being deformed without force after installation.
[0040] like Figure 3 As shown, in one embodiment, the cooking device 100 also includes a fastener 150, which is detachably connected to one end of the connecting column 113 away from the inner pot 110 and passes through the connecting hole 1221. In this embodiment, the fastener 150 is a fastening bolt connected to the connecting column 113. In other embodiments, the fastener 150 can also be a snap-on part, etc.
[0041] When installing the temperature measuring component 120 of the cooking device 100 provided in the above scheme, the connecting column 113 is first fixedly connected (for example, welded) to the side wall 112, and the elastic member 130 is sleeved on the outer periphery of the connecting column 113. Then, the temperature measuring tube 121 is inserted into the temperature measuring hole 1121 after passing through the sealing hole 141 of the sealing ring. At this time, the connecting column 113 passes through the through hole 145 of the sealing member 140 and the connecting hole 1221 of the connecting piece 122 in sequence, and the connecting column 113 is fixed by the fastener 150. At this time, the elastic member 130 is abutted by the connecting piece 122 and the side wall 112 of the inner pot 110.
[0042] In the above scheme, an elastic member 130 is provided to be sleeved on the outer periphery of the connecting column 113, and the two ends of the elastic member 130 are respectively abutted against the connecting piece 122 and the side wall 112 of the inner pot 110, and the elastic force of the elastic member 130 is utilized to make the elastic member 130 and the connecting piece 122, and the elastic member 130 and the side wall 112 stably contact each other, and at the same time, the elastic member 130 is made of a conductive material, so that the connecting piece 122 of the temperature measuring component 120 and the side wall 112 can be conductively connected, thereby realizing the grounding of the temperature measuring tube 121. Compared with the grounding method of using a grounding plate and equipped with a grounding wire in the prior art, the temperature measuring component 120 and the inner pot 110 in the cooking device 100 provided by the present application are reliably conductively connected, and the existing inner pot 110 is used for grounding, and there is no need to weld a grounding plate, a grounding wire, etc. At the same time, the process steps of welding a grounding plate are also omitted during installation, thereby reducing production costs and improving product market competitiveness.
[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
