[0029] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 A schematic diagram of the structure of a cooking device 100 in an embodiment of the present application at different viewing angles is shown. The cooking device 100 provided in an embodiment of the present application may be a steam oven, an oven, or any other device with a cooking function.

[0030] like Figure 1 and Figure 2 As shown, the cooking device 100 includes an inner pot 110, a heating element 120 and a steam component 130, wherein the inner pot 110 is provided with a cooking cavity 111. Figure 1 As shown, the cooking cavity 111 has an opening at the front end, and the cooking cavity 111 is used for placing and cooking food.

[0031] like Figure 2As shown, the heating element 120 is connected to the inner pot 110 and is located in the cooking cavity 111. The heating element 120 is used to generate heat, and the heat acts on the food inside the cooking cavity 111, so as to heat and cook the food. In the application, the heat generated by the heating element 120 can also be used to heat the steam pipe 132 described below and the water flow inside it.

[0032] Combination Figure 1 and Figure 2 As shown, the steam component 130 includes a water tank 131 and a steam pipe 132, wherein the water tank 131 includes a water storage chamber for storing water. The water storage chamber is used to store water. When the cooking device 100 is a steam oven, the water tank 131 can also be used to hold water for the steaming function. A steam channel is provided inside the steam pipe 132, and the steam pipe 132 is provided with a spray hole 1331 connected to the steam channel. The upstream of the steam channel is connected to the water storage chamber, so that the water in the water storage chamber can flow into the steam channel and absorb the heat generated by the heating element 120 inside the steam channel, thereby generating steam. The spray hole 1331 is located downstream of the steam channel, so that after the water inside the water storage chamber enters the steam channel, it can absorb heat along the steam channel and evaporate into steam during the flow process, and then spray out from the spray hole 1331. Figure 3 As shown, Figure 3 A schematic structural diagram of a steam pipe 132 and a heating element 120 in an embodiment of the present application is shown. The steam pipe 132 is attached to the surface of the heating element 120, so that when there is no water in the steam pipe 132, the heating element 120 can heat the steam pipe 132 to keep the steam pipe 132 in a high temperature state. When steam needs to be introduced into the cooking cavity 111, the steam pipe 132 and the water inside the steam pipe 132 can quickly absorb the heat of the heating element 120, so that the water evaporates into water vapor, thereby achieving rapid generation of water vapor.

[0033] Since the steam pipe 132 is fitted with the heating pipe to absorb the heat of the heating pipe, the temperature in the steam channel is extremely high. When water is sprayed into the steam channel, it will immediately vaporize into water vapor. Under the influence of the subsequent water flow of the water supply pump 134 described below and the vaporization effect, the water is dispersed into small water droplets, which sputter and flow in the steam pipe 132, which is conducive to the rapid evaporation of water, and the small water droplets are transported to the downstream along the steam channel. During the transportation process, these water droplets constantly collide with the high-temperature inner wall of the steam pipe 132 that has not yet been cooled due to contact with water, and further vaporize. In this process, a high-pressure environment is formed in the steam channel, and finally the water vapor is ejected at high speed through the downstream nozzle 1331.

[0034] like Figure 1 and Figure 3As shown, in one embodiment, the heating element 120 is located at the top of the cooking cavity 111, and the steam pipe 132 attached to the surface of the heating element 120 is also located at the top of the cooking cavity 111, so that the water vapor is sprayed from top to bottom into the cooking cavity 111, and it diffuses in the cooking cavity 111 or flows faster with the airflow toward the area where the food is placed in the cooking cavity 111. In other embodiments, the heating element 120 can also be located at the bottom of the cooking cavity 111 or other areas, in which case it can be set above the spray hole 1331 or toward the area where the food is placed in the cooking cavity 111, and the water vapor is sprayed from the spray hole 1331. The power is used to mix into the airflow in the cooking cavity 111 and flow and diffuse in the cooking cavity 111 with the airflow.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the cooking device 100 includes a fan 150, which is located on the side of the cooking cavity 111 away from the opening and is arranged toward the opening to drive the airflow in the cooking cavity 111 to flow, thereby driving the water vapor sprayed from the spray hole 1331 to diffuse in the cooking cavity 111 along with the airflow, thereby avoiding the problem of uneven humidification during the cooking process. In some embodiments, the fan 150 is directed toward the area in the cooking cavity 111 for placing food, and the fan 150 blows the water vapor sprayed from the spray hole 1331 onto the food, so as to humidify and roast the food. In this embodiment, the fan 150 is a convection fan 150.

[0036] like Figures 2 to 5 As shown, in one embodiment, the steam component 130 also includes a nozzle 133, which is rotatably connected to the steam pipe 132, and a spray hole 1331 is opened in the nozzle 133 to control the angle of the steam spray direction, and the angle with the best effect can be selected to spray steam. For example, before the cooking device 100 is working, the direction of the nozzle 133 can be adjusted in advance, and the pre-adjusted direction of the nozzle 133 is maintained during the cooking process of the cooking device cooking food, so that the steam in the spray hole 1331 is directly sprayed on the cooked food, or the steam in the spray hole 1331 is sprayed to other areas in the cooking cavity 111 and then flows to the food along with the airflow in the cooking cavity 111. In other embodiments, the angle of the nozzle 133 can also be adjusted according to the cooking requirements of the food during the operation of the cooking device 100.

[0037] like Figure 5 As shown, in the present embodiment, the nozzle 133 adopts a spherical connection structure to achieve multi-angle rotation. In other embodiments, the nozzle 133 may also adopt other connection structures capable of achieving multi-angle rotation to achieve the rotation of the nozzle 133, without limitation.

[0038] In other embodiments, the spray holes 1331 may also be opened on the peripheral wall of the steam pipe 132, and the spray holes 1331 may be dispersed on the peripheral wall of the steam pipe 132 to disperse the water vapor toward the cooking cavity 111, or the spray holes 1331 may also be set toward the area in the cooking cavity 111 for placing and cooking food.

[0039] like Figure 1 As shown, in one embodiment, the steam component 130 also includes a water supply pipe (not shown) and a water supply pump 134, the two ends of the water supply pipe are respectively connected to the water tank 131 and the steam pipe 132, the water supply pump 134 is connected to the water supply pipe and acts on the water in the water supply pipe, the water supply pump 134 is used to provide power for the water flow in the water supply pipe, and the water supply pump 134 is configured to drive the water in the water supply pipe to be intermittently sprayed into the steam pipe 132. When water is intermittently sprayed into the steam pipe 132, the amount of water entering the steam pipe 132 each time is small and discontinuous. Since a strong heat exchange will be generated when the water with a lower temperature enters the high-temperature steam pipe 132, the water will be partially vaporized at this time, but the temperature of the steam pipe 132 will also drop. If water is continuously introduced, the steam generation efficiency in the steam pipe 132 will gradually decline. Therefore, the intermittent spraying of water into the steam pipe 132 enables the temperature of the steam pipe 132 to be increased again under the heating of the heating element 120 during the water spraying interval, thereby ensuring the stability of the steam generation efficiency in the steam pipe 132. Moreover, when water is intermittently sprayed into the steam pipe 132, the flow rate of water entering the steam pipe 132 is relatively high. When the water pressure is relatively high, the water can be directly sprayed onto the side wall of the steam pipe 132. Combined with the vaporization of water due to contact with the steam pipe 132, the water will be dispersed into fine water droplets, which will splash and flow in the steam pipe 132, which is conducive to the rapid evaporation of water.

[0040] like Figure 1 As shown, in one embodiment, the steam component 130 further includes a valve body 135, which is connected to the water supply pipe and is used to control the on-off of the water supply pipe. When water vapor is needed in the cooking cavity 111, the valve body 135 is controlled to open, and the water supply pipe is connected to the water tank 131 and the steam pipe 132. Under the action of the water supply pump 134, the water in the water tank 131 flows into the steam pipe 132. When water vapor is not needed in the cooking cavity 111, the valve body 135 is closed, and the water supply pipe is in a disconnected state. By setting the valve body 135 to control the on-off of the water supply pipe, water vapor can enter the cooking cavity 111 only when the valve body 135 is opened, so that the timing of steam generation can be selected, thereby adapting to various cooking needs. In this embodiment, the valve body 135 is a solenoid valve.

[0041] like Figure 4As shown, in one embodiment, the circumferential surface of the steam pipe 132 includes an inwardly concave groove surface 1321, and the groove surface 1321 is a contoured surface matching the circumferential surface of the heating element 120. When the steam pipe 132 is attached to the heating element 120, the heating element 120 is partially attached to the groove surface 1321 to increase the contact area between the steam pipe 132 and the heating element 120, thereby increasing the efficiency of the steam pipe 132 and the water therein to absorb the heat of the heating element 120, thereby improving the efficiency of the water in the steam pipe 132 evaporating into steam.

[0042] In one embodiment, the heating element 120 includes a plurality of connected bending sections 121, the bending sections 121 are U-shaped, and the directions of adjacent bending sections 121 are opposite, and the steam pipe 132 is at least attached to one bending section 121 of the heating element 120. In this embodiment, the steam pipe 132 is attached to each bending section 121 of the heating element 120. Figure 4 In the illustrated embodiment, the heating element 120 includes five bent segments 121 connected in sequence. In other embodiments, the heating element 120 may also have other structures.

[0043] In one embodiment, the cooking device 100 further includes a heating outer tube 140, which is located at the periphery of the heating element 120 and is spaced apart from the heating element 120 to prevent the remaining heat from being insufficient to cook the food after the heat of the heating element 120 is absorbed by the steam pipe 132. Figure 3 and Figure 4 As shown, the steam pipe 132 is attached to the side of the heating element 120 away from the outer heating tube 140. In one embodiment, the cooking device 100 further includes a back heating tube located at the back side of the cooking cavity 111, which together with the outer heating tube 140 and the heating element 120 realizes uniform heating of the cooking cavity 111.

[0044] The cooking device 100 provided in the above scheme, by providing a steam pipe 132 attached to the heating element 120, uses the heat generated by the heating pipe when working to heat the steam pipe 132, so that the steam pipe 132 is kept at a high temperature, and when water enters the steam pipe 132, water vapor can be instantly generated. It uses the heat of the existing heating pipe, has low cost, and has high efficiency in generating water vapor, thus solving the problem of low efficiency in existing steam generation. At the same time, it is also possible to control whether steam is passed into the cooking cavity 111 by controlling whether water is passed into the steam pipe 132, thereby realizing the selectable timing of steam generation, thereby adapting to various cooking needs. It is also possible to control the amount of steam entering the cooking cavity 111 by controlling the amount of steam passed into the steam pipe 132, thereby solving the problem of difficult control of humidification amount.

[0045] 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.

[0046] 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.
