Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to an oil stain detection device and a cooking device. Background Art

[0002] Cooking equipment, such as steam ovens, usually uses radiant heat from electric heating elements to bake food. According to different needs of baked food, the temperature of the baking cooking device can generally be adjusted within the range of 50°C to 250°C. The back of the inner shell of the cooking device with baking function is provided with a hot air blower baffle, and the back of the hot air blower baffle is provided with a heating tube and a fan blade, so that the back of the hot air blower baffle forms a hot air cavity that circulates hot air with the cooking cavity.

[0003] During the operation of the cooking device, the oil stains generated in the cooking cavity will splash onto the hot air blower baffle. At the same time, the hot air blower baffle is also provided with an air outlet and an air inlet for hot air circulation. The oil stains can enter the back of the baffle through the air outlet and the air inlet, causing the oil stains to accumulate on the back of the hot air blower baffle. On the one hand, since the hot air blower baffle is usually fixedly connected to the inner pot, only the air outlet and the air inlet can observe the inside of the hot air blower baffle, causing the user to be unable to know whether the back of the baffle has accumulated oil stains in time, and also unable to clean the back of the baffle in time. In the long run, the accumulated oil stains will cause the inner pot of the cooking device to have problems such as odor. Summary of the invention

[0035] See also Figure 1 , Figure 1 The schematic diagram of the structure of a cooking device 100 in an embodiment of the present application is shown. The cooking device 100 provided in an embodiment of the present application can be an oven, a steam oven, or any existing device with a cooking function. The cooking device 100 includes an oil stain detection device 110 as described in any of the following embodiments, and also includes an inner pot 120. The baffle 111 in the oil stain detection device 110 is connected to the inner pot 120. The inner pot 120 is hollow inside and together with the baffle 111, forms a cooking cavity 121 with an open front end for cooking food. Figure 1 As shown, the baffle 111 is located on a side of the cooking cavity 121 away from the opening.

[0036] Combination Figure 2 As shown, Figure 2FIG. 1 shows an exploded schematic diagram of an oil stain detection device 110 in an embodiment of the present application. The oil stain detection device 110 provided in an embodiment of the present application is used to detect the oil stain content as a basis for determining whether the oil stain needs to be cleaned. Figure 2 As shown, the oil pollution detection device 110 includes a baffle 111, a light source 112 and a dirt accumulation member 113. The baffle 111 is provided with a plurality of light transmission holes 1111 penetrating the baffle 111, so that light beams can pass through the light transmission holes 1111.

[0037] Combination Figure 3 , as shown, Figure 3 FIG. 1 is a cross-sectional schematic diagram of an oil stain detection device 110 in an embodiment of the present application, wherein a light source 112 is located on the back side of a baffle 111, and the light source 112 is located on the side of the baffle 111 away from the cooking cavity 121. Figure 3 As shown, the light source 112 is used to emit a light beam toward the light-transmitting hole 1111, so that the user can observe the light beam passing through the light-transmitting hole 1111 from the side of the baffle 111 facing the cooking cavity 121. In this embodiment, the light source 112 can be an LED lamp (light-emitting diode lamp), and in other embodiments, the light source 112 can also be an incandescent lamp, etc.

[0038] like Figure 2 and Figure 3 As shown, the dirt accumulation piece 113 is located between the light source 112 and the baffle 111, and the dirt accumulation piece 113 is in the optical path of the light beam and is used to propagate the light beam. The dirt accumulation piece 113 is configured to be able to absorb oil on its surface, and the oil on the surface of the dirt accumulation piece 113 interferes with the propagation of the light beam by the dirt accumulation piece 113. The amount of oil on the surface of the dirt accumulation piece 113 and the propagation effect of the dirt accumulation piece 113 on the light beam are in an inverse correlation. The propagation effect of the dirt accumulation piece 113 on the light beam can be judged by observing the amount of light observable from the light transmission hole 1111 after the light source 112 propagates through the dirt accumulation piece 113, thereby inferring the amount of oil on the surface of the dirt accumulation piece 113, and then knowing the oil content in the space where the dirt accumulation piece 113 is located, thereby achieving the effect of inferring the oil content in the space on the back side of the baffle 111 by observing the amount of light of the light beam passing through the light transmission hole 1111, thereby solving the problem that the oil stains on the back side of the baffle 111 cannot be observed, and achieving the technical effect of automatically reminding the user to clean the back side of the baffle 111.

[0039] like Figure 2 and Figure 3As shown, in one embodiment, the dirt collecting member 113 is made of a porous material, and the holes inside it are the optical path of the light. Oil can adhere to the surface of the dirt collecting member 113 and the holes inside it. It can be understood that the accumulation of oil on the surface of the porous material as a whole and in the holes inside the porous material are both the adsorption of oil on the surface of the porous material, and the difference lies in the outer surface and the inner surface. When oil accumulates in the holes inside the dirt collecting member 113, the oil at least partially blocks the holes for light to pass through, thereby interfering with the propagation effect of light in the dirt collecting member 113. In a direction parallel to the optical path, the projection of the dirt collecting member 113 on the baffle 111 at least covers a portion of the light-transmitting hole 1111. Figure 3 In the illustrated embodiment, the projection of the dirt-collecting member 113 on the baffle 111 completely covers all the light-transmitting holes 1111. At this time, the amount of oil and dirt absorbed by the dirt-collecting member 113 is determined by comparing the amount of light emitted from the light-transmitting holes 1111 in the initial state with the amount of light emitted from the light-transmitting holes 1111 after long-term use. In other embodiments, the projection of the dirt-collecting member 113 on the baffle 111 may only cover part of the light-transmitting holes 1111. At this time, the amount of oil and dirt absorbed by the dirt-collecting member 113 is determined by comparing the amount of light emitted from the light-transmitting holes 1111 covered by it with the amount of light emitted from the light-transmitting holes 1111 not covered. In other embodiments, the dirt-collecting member 113 may also be a reflective member whose surface can absorb oil and dirt.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the oil stain detection device 110 further includes a back plate 114, which is located on the back side of the baffle 111, and the back plate 114 and the baffle 111 together enclose a hot air cavity 117 where oil stains are present, and the dirt accumulation member 113 is located in the hot air cavity 117. In the cooking device 100, the hot air cavity 117 is used to communicate with the cooking cavity 121 for hot air circulation. Since oil stains are generated during the cooking process of the food in the cooking cavity 121, the oil stain particles may enter the hot air cavity 117 with the circulating hot air and accumulate in the hot air cavity 117. When the dirt accumulation member 113 is located inside the hot air cavity 117, the oil stain content in the hot air cavity 117 where the dirt accumulation member 113 is located can be inferred by observing the amount of light beams passing through the light transmission hole 1111 from the side of the baffle 111 facing the cooking cavity 121.

[0041] like Figure 2 and Figure 3As shown, in one embodiment, the oil pollution detection device 110 also includes a sleeve 115. In this embodiment, the sleeve 115 is made of metal material to facilitate processing, but it is not limited to this. In other embodiments, the sleeve 115 can also be made of resin material. One end of the sleeve 115 is connected to the baffle 111 and is located opposite to the light-transmitting hole 1111. A placement cavity 1151 is provided inside the sleeve 115 and is arranged in a direction parallel to the light path. The dirt accumulation piece 113 is arranged in the placement cavity 1151 to limit the position of the dirt accumulation piece 113 to prevent the dirt accumulation piece 113 from being offset relative to the light path and affecting the light output of the light-transmitting hole 1111. A through hole 1152 is provided on the circumferential surface of the sleeve 115 for connecting the placement cavity 1151 and the hot air cavity 117, so that the oil and dirt in the hot air cavity 117 can enter the dirt accumulation piece 113 in the placement cavity 1151 through the through hole 1152 and adhere to the surface of the dirt accumulation piece 113, thereby interfering with the light path propagation effect of the dirt accumulation piece 113.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the light source 112 is located on the side of the back plate 114 away from the baffle 111, and the light source 112 is located outside the hot air chamber 117 to prevent the light source 112 from being affected by the heat, water vapor and oil in the circulating hot air, and the back plate 114 is provided with a light emitting hole 1141 that passes through the back plate 114, and the light emitting hole 1141 is opposite to the light source 112 so that the light beam passes through the light emitting hole 1141, so that the light beam can pass through the light emitting hole 1141 into the hot air chamber 117.

[0043] like Figure 2 and Figure 3 As shown, in one embodiment, the oil pollution detection device 110 further includes a light guide column 116, which is a light-transmitting material. In this embodiment, the light guide column 116 is a glass material. In other embodiments, the light guide column 116 can also be a light-conducting resin material with high temperature resistance. The light guide column 116 is arranged through the light exit hole 1141, so that the light beam emitted by the light source 112 enters the hot air chamber 117 through the light guide column 116.

[0044] like Figure 3 As shown, in one embodiment, one end of the light guide column 116 away from the light source 112 extends into the hot air chamber 117, and one end of the sleeve 115 away from the baffle 111 is connected to the light guide column 116, so that the positions of the sleeve 115 and the light guide column 116 are relatively fixed.

[0045] like Figure 3 As shown, in one embodiment, the dirt collecting piece 113 is located at one end of the sleeve 115 close to the baffle 111, and the dirt collecting piece 113 and the light guide column 116 are spaced apart in a direction parallel to the light path to make it easier for oil and dirt to pass through the through hole 1152 of the sleeve 115 and enter the dirt collecting piece 113.

[0046] In the above scheme, the oil stain detection device 110 is provided. When there is no oil stain on the back side of the baffle 111, the light from the light source 112 passes through the light guide column 116, the placement cavity 1151 in the sleeve 115, the dirt accumulation piece 113 and the light-transmitting hole 1111 opened by the baffle 111 at one time, so that it can be observed from the open part of the cooking cavity 121; when there is oil stain on the back side of the baffle 111, the oil stain enters the placement cavity 1151 in the sleeve 115 through the through hole 1152 of the sleeve 115, and is adsorbed on the surface of the dirt accumulation piece 113, and enters the holes inside the dirt accumulation piece 113 that block the porous material, thereby reducing the amount of light that can pass through the dirt accumulation piece 113, thereby reducing the amount of light that can pass through the light transmission hole 1111, so that the degree of oil stain accumulation on the back side of the baffle 111 can be judged according to the light output of the light transmission hole 1111, so as to timely judge whether the back side of the baffle 111 needs to be cleaned.

[0047] Combination Figures 4 to 6 As shown, in one embodiment, the baffle 111 can be relative to the inner container 120 in the following manner: Figure 1 and Figure 4 The working position shown and Figure 5 and Figure 6 The baffle 111 is rotatably arranged between the cleaning positions shown in the figure, so as to clean the baffle 111 when it needs to be cleaned. Figure 4 and Figure 6 As shown, the baffle 111 includes an outer end surface 1112 and an inner end surface 1113 disposed opposite to each other. Figure 1 and Figure 4 As shown, when the baffle 111 is in the working position, the outer end surface 1112 faces the opening and is parallel to the plane where the opening is located. At this time, the baffle 111 separates the hot air cavity 117 and the cooking cavity 121, so that the cooking cavity 121 can be used to cook food, and as shown in FIG. Figures 1 to 3 As shown, at this time, the light-transmitting hole 1111 is aligned with the light source 112, so that the light beam emitted by the light source 112 can be transmitted along the Figure 3 The light path shown passes through the light-transmitting hole 1111, so as to observe the light output from the light-transmitting hole 1111. Figure 4 and Figure 6 As shown, when the baffle 111 is in the cleaning position, the inner end surface 1113 is set at an angle with the plane where the opening is located, so as to reach into the gap between the inclined baffle 111 and the inner liner 120 to clean the inner end surface 1113 of the baffle 111 and the end surface of the back plate 114 facing the baffle 111.

[0048] like Figure 6As shown, in one embodiment, the angle of rotation of the baffle 111 between the working position and the cleaning position is not less than 90°. At this time, the gap between the baffle 111 and the inner tank 120 is larger, and the inner end surface 1113 of the baffle 111 is tilted toward the direction of the opening to facilitate cleaning of the inner end surface 1113 of the baffle 111, the end surface of the back panel 114 facing the baffle 111, and the components inside the hot air chamber 117.

[0049] like Figures 4 to 6 As shown, in one embodiment, the cooking device 100 further includes a flip assembly 130, which is connected to the inner pot 120 and the baffle 111 and is used to drive the baffle 111 to move relative to the inner pot 120 in the following manner: Figure 1 and Figure 4 The working position shown and Figure 5 and Figure 6 Rotate between the cleaning positions shown.

[0050] like Figure 4 and Figure 6 As shown, in one embodiment, the flip assembly 130 includes a base 131 and a connecting rod 132. The base 131 is located on the side of the baffle 111 away from the cooking cavity 121. In this embodiment, the base 131 is located inside the hot air cavity 117 and connected to the end surface of the back plate 114 facing the baffle 111. Figure 4 and Figure 6 As shown, two ends of the connecting rod 132 are rotatably connected to the base 131 and the baffle 111 respectively, so that the baffle 111 can be flipped relative to the base 131.

[0051] like Figure 4 and Figure 6 As shown, in one embodiment, the flip assembly 130 also includes an active rod 133 and a fixed rod 134, the fixed rod 134 is connected to the inner end surface 1113, and the two ends of the active rod 133 are rotatably connected to the base 131 and the fixed rod 134 respectively, one end of the connecting rod 132 connected to the baffle 111 and the end of the active rod 133 connected to the fixed rod 134 are spaced apart in a direction perpendicular to the inner end surface 1113, and one end of the active rod 133 connected to the base 131 and the end of the connecting rod 132 connected to the base 131 are spaced apart in a direction parallel to the inner end surface 1113 when the baffle 111 is in the working position, so that the active rod 133, the fixed rod 134, the connecting rod 132 and the base 131 together form a four-linkage 132 structure, thereby realizing that when the active rod 133 rotates, the baffle 111 is driven to flip.

[0052] like Figure 4 and Figure 6As shown, in one embodiment, the flip assembly 130 further includes a driving member 135, which is connected to the active rod 133 and is used to drive the active rod 133 to rotate relative to the base 131, thereby driving the baffle 111 to flip. Figure 4 and Figure 6 As shown, in this embodiment, the flip assembly 130 also includes a conversion member 136, which is used to convert the rotation direction of the driving shaft of the driving member 135 to achieve right-angle reversal, so that the driving member 135 can be located outside the hot air chamber 117 and installed on the end surface of the back plate 114 away from the baffle 111, thereby avoiding the heat, water vapor and oil in the hot air chamber 117 from interfering with the driving member 135.

[0053] like Figure 6 As shown, in one embodiment, the fixed rod 134 is arranged in a direction perpendicular to the inner end surface 1113, and the connecting rod 132 and the active rod 133 are respectively connected to the two ends of the fixed rod 134 to facilitate the installation of the connecting rod 132 and the active rod 133. In other embodiments, the fixed rod 134 can also be inclined relative to the inner end surface 1113.

[0054] like Figure 6 As shown, in one embodiment, the connecting rod 132 is connected to one end of the fixing rod 134 close to the baffle 111 to facilitate the installation of the connecting rod 132, to avoid the connecting rod 132 connecting to the baffle 111 and interfering with the inherent structure of the baffle 111, thereby avoiding the flipping mechanism interfering with other functions of the baffle 111 and avoiding an increase in production costs.

[0055] like Figure 6 As shown, in one embodiment, the base 131 is arranged in the height direction, and one end of the active rod 133 connected to the base 131 and one end of the connecting rod 132 connected to the base 131 are arranged at intervals in the height direction, so that when the baffle 111 is flipped relative to the inner container 120, the flip axis around which it rotates is arranged in the horizontal direction. In other embodiments, the base 131 can also be arranged in the horizontal direction, in which case the active rod 133 and the connecting rod are spaced in the horizontal direction, and then the flip axis around which the baffle 111 rotates relative to the inner container 120 is arranged in the height direction.

[0056] like Figure 6 As shown, in one embodiment, one end of the connecting rod 132 connected to the base 131 is located above one end of the active rod 133 connected to the base 131, so that the active rod 133 rotates to drive the baffle 111 to flip. In other embodiments, one end of the connecting rod 132 connected to the base 131 may be located below one end of the active rod 133 connected to the base 131, so that the active rod 133 can rotate to drive the baffle 111 to flip.
