Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a cooking device. BACKGROUND

[0002] The cooking device, for example, a steam oven, usually adopts two ways of direct steam and transpiration steam for the steam function. The direct steam is generated by heating normal temperature water through an internal evaporator and then sprayed onto food through a pipeline. The transpiration steam is generated by heating water through a bottom heating device to produce boiling steam for steaming. Both of the above two ways directly heat normal temperature water, which needs the normal temperature water to contact the heating element with a surface temperature of up to 260℃ for a short time to generate steam.

[0003] However, the high frequency contact between the heating element and the normal temperature water and the frequent cold and hot alternation put high requirements on the material properties of the heating element. Currently, the heating element is usually made of a metal heating disc and a non-metal material sintered together. Long-term cold and hot impact will cause cracks at the sintered part, resulting in heating failure, and further causing the problem of undercooked steamed food.

[0004] Meanwhile, the steam generated by the heating element in the closed cooking space is discharged through a small air pipe. When the water quality is hard, scale is easily generated inside the heating element or the air pipe in the cooking space, which blocks the steam discharge, further reduces the steam amount, and causes the problem of undercooked steamed food. CONTENT OF THE INVENTION

[0005] Therefore, it is necessary to provide a cooking device to solve the problems of cracks and scale of the heating element in the steaming function of the cooking device.

[0028] Referring to Figure 1 , Figure 1 The structure of the cooking device 100 in an embodiment of the present application is shown. The cooking device 100 provided by the embodiment of the present application can be a steamer, a steam oven, etc. As shown in Figure 1 The cooking device 100 includes an inner container 110 and a water supply assembly 120. The inner container 110 is provided with a cooking space 111 for placing and cooking food. As shown in Figure 1 The cooking device 100 further includes a door body 140 covering the inner container 110. The cooking space 111 is provided with a front opening 1111. When the door body 140 covers the inner container 110, the door body 140 covers the opening 1111 to seal the cooking space 111.

[0029] In combination with Figure 2 As shown, Figure 2The image shows a front view of a cooking device 100 according to one embodiment of the present application. In one embodiment, the cooking device 100 further includes a heating element 130, which is connected to the inner pot 110 and located at the top inside the cooking space 111, for raising the temperature inside the cooking space 111, thereby achieving high-temperature cooking of food.

[0030] like Figure 2 As shown, the cooking appliance 100 also includes a placement tray 150 located inside the cooking space 111. The placement tray 150 is used to hold ingredients. Conventionally, the placement tray is retractably connected to the inner wall of the inner pot 110 for easy access to ingredients. Figure 2 As shown, the heating element 130 is located above the placement plate so that the heating element 130 can cook the food located on the placement plate 150.

[0031] like Figure 1 As shown, the water supply assembly 120 includes a water supply pipe 121 arranged along the water supply path and connected to the cooking space 111, and a water tank 124 for storing water. One end of the water supply pipe 121 is connected to the water tank 124, and the other end is connected to the cooking space 111 to form a water supply path. The water supply assembly 120 also includes, as shown in the figure... Figure 3 The pressurized atomizing element 122 shown is located on the water supply path and acts on the water flow in the water supply pipe 121 to atomize the water into water mist. After the water flow is atomized into water mist under the action of the pressurized atomizing element 122, the water mist continues to flow in the water supply pipe 121 until it flows into the cooking space 111, so as to achieve direct spraying of water mist into the cooking space 111. The water mist has a high temperature in the cooking space 111 under the action of the heating element 130. The water mist quickly absorbs the temperature and vaporizes into steam, becoming close to the original temperature of the cooking space 111, so as to avoid the water mist affecting the temperature field in the cooking space 111, and thus avoid the water mist affecting the cooking food. In this embodiment, the pressurized atomizing element 122 has a pressurized and atomizing nozzle to achieve the atomization of water into water mist.

[0032] In one embodiment, the inner liner 110 has a steam inlet 1112, and a water supply pipe 121 is connected to the steam inlet 1112 so that the water mist in the water supply pipe 121 can enter the cooking space 111 through the steam inlet 1112.

[0033] In one embodiment, the inner liner 110 includes a back side 112 for defining the cooking space 111 and facing the opening 1111. It is understood that the inner liner 110 also includes a top surface, a bottom surface, and left and right side surfaces. The steam inlet 1112 is opened on the back side 112 so that the water mist absorbs heat and vaporizes into steam, which can be accelerated to diffuse within the cooking space 111 by the wind force of the fan located on the back side of the cooking space 111.

[0034] In one embodiment, the steam inlet 1112 is located at the bottom end of either side edge of the back side 112, such as... Figure 2 As shown, the steam inlet 1112 is located below the placement tray 150 to prevent water mist from directly spraying onto the food and affecting the uniformity of steaming. Figure 2 As shown, the steam inlet 1112 is located at the bottom of the right edge of the back side 112. In other embodiments, the steam inlet 1112 may also be located at the bottom of the left edge of the back side 112.

[0035] like Figure 3 As shown, in one embodiment, the water supply assembly 120 further includes a control valve 123. The control valve 123 is located on the water supply path and upstream of the pressurized atomizing element 122. The control valve 123 acts on the water flow in the water supply pipe 121 to control the flow rate of the water flow. By controlling the flow rate of the water flow through the control valve 123, the flow rate of the water mist entering the cooking space 111 is controlled. The control valve 123 also controls the water flow into the pressurized atomizing element 122, thereby controlling the amount and effect of the water mist atomized by the pressurized atomizing element 122.

[0036] like Figure 3 As shown, in one embodiment, the water supply assembly 120 further includes a control valve 123, which is located on the water supply path and downstream of the pressurizing atomizing element 122. The control valve 123 acts on the water mist in the water supply pipe 121 to control the flow rate of the water mist, directly controlling the flow rate of the water mist entering the cooking space 111.

[0037] In one embodiment, the control valve 123 is an electronic expansion valve. An expansion valve is a throttling element whose main function is to control the conversion process of liquid from a high-pressure liquid state to a low-pressure gaseous state. During circulation, the expansion valve throttles the high-pressure liquid to a low-pressure state, thereby achieving liquid evaporation. The electronic expansion valve can adjust the flow rate of the incoming liquid according to a preset program. Therefore, in this embodiment, the control valve 123 is connected to the pressurized atomizing element 122 and acts on the conversion process from a high-pressure liquid state to a low-pressure gaseous state within the pressurized atomizing element 122.

[0038] In one of the embodiments, the cooking device 100 comprises a flow monitoring component located on the water supply path and downstream of the control valve 123 and the pressurized atomizing component 122 to monitor the flow of the water mist, and a controller configured to control the opening size of the control valve 123 according to the flow monitored by the flow monitoring component, so as to adjust the opening size of the control valve 123 and the amount of water mist entering the cooking space 111, thereby adjusting the amount of water mist entering the cooking space 111. In some embodiments, a plurality of preset menus adapted to different cooking materials can be preset before the cooking device 100 is shipped, each preset menu corresponding to a corresponding water mist flow, and in use, the selected preset menu can be directly adjusted to the preset water mist flow, so as to facilitate the adjustment of the cooking temperature and humidity.

[0039] As shown in Figure 1 and Figure 3 In one of the embodiments, the cooking device 100 further comprises a protection box 125 comprising a shell 1251 enclosing a placement space 1252, the pressurized atomizing component 122 and the control valve 123 are located in the placement space 1252, and the shell 1251 is used to protect the pressurized atomizing component 122 and the control valve 123 from being impacted, etc. The shell 1251 is provided with an inlet 1253 and an outlet 1254 both used to connect the water supply pipe 121, in the present embodiment, the inlet 1253 and the outlet 1254 are used for the water supply pipe 121 to pass through to connect the pressurized atomizing component 122, and in other embodiments, the inlet 1253 and the outlet 1254 can also connect the water supply pipe 121, at this time, the inlet 1253 and the outlet 1254 are additionally provided with a pipeline connected to the pressurized atomizing component 122.

[0040] In the above scheme, by providing the pressurized atomizing component 122 located on the water supply path, the pressurized atomizing component 122 atomizes the water flow in the water supply pipe 121 into water mist, so that the water mist is directly sprayed into the cooking space 111 by the water supply assembly 120, and the water mist has a relatively high temperature under the action of the heating component 130 in the cooking space 111, and the water mist quickly absorbs the temperature to become similar to the original temperature of the cooking space 111, on the one hand, the water mist avoids affecting the temperature field in the cooking space 111, thereby avoiding affecting the cooking material, and on the other hand, the water mist has a larger surface area, which is more easily evaporated, and only needs to be directly introduced into the cooking space to be directly realized by the heating component 130 of the cooking device 100 for heating the internal temperature of the cooking space 111, so that the heating disc and the steam generator for heating water to vaporize water can be directly cancelled, which not only avoids the inconvenience of maintenance and repair caused by the complexity of the components in the inner container 110, but also avoids the problem of scale blocking the steam hole of the steam generator due to scale.

[0041] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0042] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
