[0002] Cooking equipment such as steam ovens will produce fumes during the cooking process, especially when baking food. Usually, the fumes and hot steam in the cooking chamber will diffuse and merge with each other. If the fumes are not filtered, they will accumulate in the exhaust pipes and equipment, and unfiltered fumes will cause odors to spread. If the hot steam is not treated, there is a risk of scalding the user, and it may cause the humidity in the kitchen to increase, which will have an adverse effect on the kitchen environment and equipment, such as damp electrical equipment, moldy walls and furniture, etc. Therefore, the fumes and hot steam of cooking equipment need to be filtered before being discharged.

[0031] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 A structural schematic diagram of a cooking device 100 in an embodiment of the present application is shown. A cooking device 100 provided in an embodiment of the present application may be a steam oven, an oven, or any device with a cooking function.

[0032] like Figure 1 and Figure 2 As shown, the cooking device 100 includes an inner pot 110 and a smoke removal assembly 120. The inner pot 110 includes a cooking cavity 111. The cooking cavity 111 is used to cook food. During the cooking process, the cooking cavity 111 will produce a mixed gas of oil smoke and steam.

[0033] like Figure 1 and Figure 2As shown, the smoke removal assembly 120 includes a smoke removal box 121 located outside the cooking cavity 111 and a smoke removal pipe 122 connected to the cooking cavity 111. The smoke removal box 121 includes a smoke removal cavity 1211 for storing filter media. The smoke removal box 121 is provided with a steam outlet 1231 located below the liquid level of the filter media in the smoke removal cavity 1211. The smoke removal pipe 122 is connected to the steam outlet 1231 to connect the cooking cavity 111 and the smoke removal cavity 1211, and is used to pass the mixed gas into the filter media. The filter media is used to cool and filter the mixed gas, which quickly cools the mixed gas from the cooking cavity 111, so that the oil smoke in the mixed gas forms small droplets, and the steam becomes small water droplets and mixes into the filter media. The filtered gas is then discharged, achieving the effect of filtering the mixed gas, thereby reducing the oil smoke or steam discharged externally.

[0034] Alternatively, if Figure 2 As shown, the smoke removal assembly 120 also includes a pump 126 connected to the smoke removal pipe 122 and acting on the mixed gas inside the smoke removal pipe 122. The pump 126 is used to pump the mixed gas in the cooking cavity 111 into the filter medium inside the smoke removal cavity 1211.

[0035] In one embodiment, the filter medium is water, preferably room temperature water or cold water. Water is more common than other media due to its universality and easy accessibility, and is convenient for daily use and access. It also has a relatively low cost, which reduces the overall maintenance cost of the cooking device 100.

[0036] Combination Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 1 shows a schematic diagram of the structure of a cooking device 100 in an embodiment of the present application. In one embodiment, a smoke removal box 121 is provided with a smoke inlet 1212 connected to a smoke removal chamber 1211. The smoke removal assembly 120 includes an extension tube 123 located in the smoke removal chamber 1211 and connected to the smoke inlet 1212. Figure 3 and Figure 4 As shown, the extension tube 123 is a bent structure, which extends from the smoke inlet 1212 toward the bottom surface of the smoke removal box 121, and then extends in the direction away from the end surface where the smoke inlet 1212 is located. The extension tube 123 is provided with a steam outlet 1231 connected to the smoke removal chamber 1211, and the height of the steam outlet 1231 is lower than the liquid level of the filter medium in the smoke removal chamber 1211, so that the mixed gas is passed into the filter medium. In other embodiments, the extension tube 123 may not be provided. In this case, the steam outlet 1231 and the smoke inlet 1212 coincide with each other, and the steam outlet 1231 is the smoke inlet 1212. The height of the smoke inlet 1212 is lower than the liquid level of the filter medium in the smoke removal chamber 1211, so that the mixed gas is passed into the filter medium.

[0037] The cooking device 100 provided in the above scheme passes the mixed gas containing oil smoke and steam in the cooking cavity 111 into the smoke removal cavity 1211, and directly passes the mixed gas into the filter medium, so that the mixed gas can fully contact with the filter medium when discharged, cool down and condense to form oil smoke particles or water vapor particles, and be "filtered" by the filter medium. The filtered gas is discharged to the outside of the cooking device 100. The filtered gas has a lower temperature and reduces the discharge of oil smoke or steam, thereby improving the user experience.

[0038] like Figures 3 to 5 As shown, in one embodiment, the smoke removal box 121 is further provided with a smoke outlet 1213, one end of the smoke outlet 1213 is connected to the smoke removal chamber 1211, and the other end is connected to the outside of the cooking device 100. In this embodiment, the cooking device 100 further includes an air guide component 130, and the smoke outlet 1213 is connected to the air guide component 130 through a pipeline. The air guide component 130 is connected to the outside and discharges the filtered mixed gas to the outside of the cooking device 100. Figure 3 and Figure 4 As shown, the height of the smoke outlet 1213 is higher than the liquid level of the filter medium in the smoke removal chamber 1211 , so that after the mixed gas passes into the filter medium, it fully contacts the filter medium and then escapes upward and is discharged from the smoke outlet 1213 .

[0039] like Figure 5 As shown, in one embodiment, the smoke removal box 121 includes a box body 1214 and a support 1215, and the support 1215 is fixedly arranged and hollow inside. Figure 1 and Figure 2 As shown, in this embodiment, the cooking device 100 further includes an upper mounting plate 140 located above the inner pot 110 , and the support 1215 is fixedly connected to the end surface of the upper mounting plate 140 facing away from the inner pot 110 .

[0040] like Figures 3 to 5 As shown, the box body 1214 is provided with an open smoke removal chamber 1211, and the box body 1214 is slidably connected to the support 1215 so that the box body 1214 can slide relative to the support 1215. Figure 5 As shown, the sliding path of the box body 1214 includes at least one liquid replacement position, such as Figure 5As shown, when the box 1214 is located at the liquid replacement position, the box 1214 at least partially protrudes from the support 1215 so that the opening of the smoke removal chamber 1211 is at least partially exposed to the outside of the support 1215, so as to facilitate the replacement or replenishment of the filter medium in the smoke removal chamber 1211, and to achieve easy replacement or replenishment of the filter medium even during operation. Preferably, the box 1214 can slide to completely detach from the support 1215, at which time the box 1214 can be rotated and the filter medium inside can be dumped to facilitate the replacement of new filter media, and also facilitate the cleaning of the box 1214 and the side wall of the smoke removal chamber 1211.

[0041] Optionally, the support 1215 is provided with holes corresponding to the smoke inlet 1212 and the smoke outlet 1213 of the box body 1214, and the positions of the smoke inlet 1212 and the smoke outlet 1213 of the box body 1214 corresponding to the support 1215 both adopt a quick-insert structure. When the box body 1214 moves relative to the support 1215, the smoke inlet 1212 and the smoke outlet 1213 of the box body 1214 can be smoothly detached from or plugged into the corresponding positions of the support 1215.

[0042] like Figure 4 As shown, in one embodiment, the steam outlet 1231 includes a main hole 12311 and a side hole 12312, wherein the main hole 12311 is opened at one end of the extension tube 123 away from the smoke inlet 1212, and the side hole 12312 is opened at the peripheral wall of the extension tube 123. In this embodiment, the number of the main hole 12311 is one, and the aperture of the main hole 12311 is consistent with the aperture of the internal channel of the extension tube 123. In other embodiments, the number of the main holes 12311 can also be multiple, all of which are arranged on the end surface of the end of the extension tube 123 away from the smoke inlet 1212.

[0043] like Figure 4 As shown, in one embodiment, the peripheral wall of the extension tube 123 includes a plurality of opening areas 1232 spaced apart along the axial direction of the extension tube 123, each opening area 1232 is provided with a side hole 12312, and the number of side holes 12312 provided in the opening area 1232 can be selectively increased in the direction from close to the smoke inlet 1212 to far away from the smoke inlet 1212, that is, the number of side holes 12312 provided in the opening area 1232 can be equal to or increased compared to the number of side holes 12312 provided in the previous opening area 1232, so that after the mixed gas enters the extension tube 123, the resistance inside the transition medium is gradually overcome, the pressure is evenly released, and uniform gas discharge and uniform contact with the transition medium are achieved. Figure 4In the illustrated embodiment, the number of side holes 12312 provided in the opening area 1232 is 1, 1, 3, 3, and 6 in the direction from the smoke inlet 1212 to the direction from the smoke inlet 1212, which is only an example and not a limitation. In other embodiments, the number of side holes 12312 provided in the opening area 1232 can be adjusted according to the diameter of the side holes 12312.

[0044] like Figure 4 As shown, in one embodiment, the number of side holes 12312 opened in the opening area 1232 is negatively correlated with the aperture of the side hole 12312, that is, the more the number of side holes 12312 opened in the opening area 1232, the smaller the aperture of the corresponding side hole 12312, so that the mixed gas is discharged evenly and smoothly when entering the transition medium.

[0045] like Figure 3 and Figure 4 As shown, in one embodiment, the smoke removal assembly 120 further includes a cover body 124, and the cover body 124 and the smoke removal box 121 are enclosed together to form a placement cavity, such as Figure 3 As shown, one end of the extension tube 123 away from the smoke inlet 1212 is located inside the placement cavity and is spaced apart from the cover body 124 to prevent the cover body 124 from blocking the steam outlet 1231 of the extension tube 123 .

[0046] like Figure 4 As shown, the cover body 124 is provided with a plurality of anti-bubble holes 1243, and the aperture of the anti-bubble hole 1243 is smaller than the minimum aperture of the side hole 12312 and the main hole 12311. When the mixed gas is discharged from the extension tube 123 due to pressure, relatively large bubbles will be generated, which will cause a large surge in the liquid surface. The anti-bubble holes 1243 provided in the cover body 124 have a small aperture, which can crush large bubbles and prevent the transition medium liquid from surging, thereby achieving full and uniform contact between the mixed gas and the transition medium, thereby improving the heat exchange effect.

[0047] In this embodiment, if Figure 4 As shown, the cover body 124 is provided with a plurality of anti-bubble slits 1244, and the width of the anti-bubble slits 1244 is smaller than the minimum aperture of the side hole 12312 and the main hole 12311. When the mixed gas is discharged from the extension tube 123 due to pressure, relatively large bubbles will be generated, which will cause a large surge in the liquid surface. The anti-bubble slits 1244 provided in the cover body 124 have a small gap width, which can crush large bubbles and prevent the transition medium liquid from surging, thereby achieving full and uniform contact between the mixed gas and the transition medium, thereby improving the heat exchange effect.

[0048] like Figure 4As shown, in one embodiment, the cover body 124 includes a main end face 1241 arranged parallel to the plane where the main hole 12311 is located. The main end face 1241 is the end face of the cover body 124 away from the end face where the smoke inlet 1212 is located (i.e., the inner end face 1216 described below). The main end face 1241 is provided with a plurality of anti-bubble holes 1243, and the anti-bubble holes 1243 are distributed in an array, so that the mixed gas can be discharged evenly and smoothly, thereby being in full and uniform contact with the transition medium.

[0049] like Figure 4 As shown, in this embodiment, the cover body 124 includes a cover peripheral surface 1242 arranged parallel to the axial direction of the extension tube 123, and the cover peripheral surface 1242 is provided with a plurality of anti-bubble seams 1244, and adjacent anti-bubble seams 1244 are equidistantly distributed, so that the mixed gas can be discharged evenly and smoothly, thereby being in full and uniform contact with the transition medium.

[0050] like Figure 3 As shown, in one embodiment, the end face of the smoke removal box 121 where the smoke inlet 1212 is opened is the inner end face 1216, and the extension tube 123 extends from the inner end face 1216 toward the end face of the smoke removal box 121 opposite to the inner end face 1216, ensuring that the extracted mixed gas can contact the transition medium more extensively, thereby ensuring the filtering and cooling effects.

[0051] like Figure 2 and Figure 5 As shown, in one embodiment, the smoke removal assembly 120 includes a temperature detection member 125 connected to the smoke removal box 121, the temperature detection member 125 is arranged toward the smoke removal chamber 1211, and is used to monitor the temperature of the filter medium. Exemplarily, the temperature detection member 125 can be an infrared temperature probe. In the process of the filter medium being fully in contact with the mixed gas, due to the existence of heat exchange, the temperature of the filter medium in the smoke removal box 121 will continue to rise, and the higher its temperature, the smaller the temperature difference between it and the mixed gas, which will cause the cooling and filtering effect of the filter medium to be worse. Therefore, the temperature detection member 125 can send a reminder signal to remind the user to take out the smoke removal box 121 and replace the filter medium therein according to the preset alarm temperature point, which means that the transition medium temperature at this time is not conducive to effectively reducing the effect of exhaust gas, so as to continuously ensure the effect of the filter medium on removing oil smoke and steam from the mixed gas.

[0052] 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.

[0053] 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.
