[0002] A steam oven is a multifunctional kitchen appliance that combines the features of a steamer and an oven. Whether in steamer mode or oven mode, the interior of the steam oven cavity needs to be heated to cook the ingredients. Accordingly, a heat dissipation component needs to be configured to dissipate heat from the interior of the steam oven. Currently, there are two main ways to dissipate heat in a steam oven. One is to use a heat dissipation chamber, a heat dissipation heating fan, and a heat dissipation duct structure to perform heat exchange on the gas; the other is to use water circulation and heat exchange pipes to achieve the effect of heat dissipation and cooling. Both methods are for processing the gas after it is discharged from the cavity.

[0032] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.
[0033] like Figure 1-Figure 6As shown, an embodiment of the utility model provides a steam oven 1, which has a cavity 100, a heating part is provided at the top and bottom of the cavity 100, an air inlet 111 is provided at the rear wall 110 of the cavity 100, and a heating fan 330 is provided at the rear side of the rear wall 110, and the position of the heating fan 330 corresponds to the position of the air inlet 111. The cavity 100 of the steam oven 1 can be used to hold food for cooking, and it has both steamer function and oven function. In the steaming mode and the baking mode, the heating parts at the top and bottom of the cavity 100 can be used as heating elements respectively to heat the space in the cavity 100. Among them, in the baking mode, the heating fan 330 at the rear side of the rear wall 110 can assist in heating the space in the cavity 100.
[0034] The steam oven 1 also includes a water inlet 500 and a water spray device 400. The water inlet 500 is arranged on the wall of the cavity 100 and is connected to the cavity 100. The water spray device 400 is installed on the inner side of the wall of the cavity 100. The water spray device 400 and the water inlet 500 are respectively arranged on the upper and lower sides of the cavity 100.
[0035] Through the water inlet 500 and the water spray device 400, cooling water vapor can be sprayed into the cavity 100 of the steam oven 1 on at least one of the upper and lower sides of the cavity 100 according to needs. By using the heating fan 330 in the steam oven 1, the water vapor sprayed by the water inlet 500 and the water spray device 400 can enter various positions of the cavity 100. Since the water mist has a small particle size, the heat exchange with the air in the cavity 100 is faster than that of liquid water, so that heat can be dissipated and cooled in the cavity 100 to improve the safety and convenience of use. Specifically, since the steam oven 1 can dissipate heat and cool in the cavity 100, the gas inside the cavity 100 can be cooled at the initial stage of exhaust, so that the exhausted gas is lower than the usual temperature, so as to improve the heat dissipation effect; and the panel of the steam oven 1 can be quickly cooled during the heat dissipation process to reduce the risk of scalding. Therefore, the heat dissipation efficiency can be improved, and the cooking interval can be reduced when cooking multiple dishes.
[0036] The water inlet 500 is an original component of the steam oven 1. In the steaming mode, water can be supplied to the cavity 100 through the water inlet 500. In specific implementation, one or more of the water inlet 500 and the water spray device 400 can be selected according to needs to spray heat dissipating water vapor into the cavity. In addition, when the water spray device 400 is used for cooling, the water spraying amount and frequency of the water spray device 400 can be adjusted, and the water inlet 500 and the water spray device 400 can be selected at different positions to meet the pressure resistance of the wall of the cavity 100.
[0037] like Figure 6As shown, a heat dissipation chamber is provided outside the cavity 100, the heat dissipation chamber is connected to the cavity 100, and a heat dissipation fan 220 is provided inside the heat dissipation chamber. The existing fan heat dissipation auxiliary system of the steam oven 1 can be utilized to discharge the water vapor in the cavity 100, which can improve the heat dissipation effect on the one hand, and prevent the internal pressure from being too high to damage the steam oven 1 and cause harm to the user on the other hand.
[0038] In a specific implementation, the space between the outer cover of the steam oven 1 and the cavity 100 can be used as a setting space for the heat dissipation chamber, such as Figure 6 As shown, it is preferably arranged above the cavity 100. Specifically, the steam oven 1 has a heat dissipation cover 210, which is installed on the upper surface of the cavity 100 and forms a heat dissipation chamber with the cavity 100. The heat dissipation fan 220 extends into the heat dissipation chamber, and the water vapor in the cavity 100 can enter the heat dissipation chamber and be dissipated by the heat dissipation fan 220. Furthermore, the fan heat dissipation system will have a corresponding operation path when it is running. When the water mist enters, it will circulate in the cavity 100 along with the air path system, and finally the heat brought out by the water vapor will be discharged at the air outlet through the air outlet.
[0039] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the heating part at the bottom of the cavity 100 is a heating plate 310, which is arranged on the bottom wall 130 of the cavity 100; the heating part at the top of the cavity 100 is a heating tube 320, which is horizontally arranged in the cavity 100 and located below the top wall 120 of the cavity 100. Specifically, the cavity 100 includes a rear wall 110, a top wall 120, a bottom wall 130 and side walls 140 arranged on both sides, and forms a structural form with one end open, and a panel assembly is arranged at the opening.
[0040] like Figure 1 As shown, the water inlet 500 is arranged at the lower side of the cavity 100, and the water spray device 400 is installed at the upper side of the cavity 100. The water inlet 500 and the water spray device 400 can spray water vapor into the cavity 100 at the lower side and the upper side respectively. In specific implementation, when the steam oven 1 is in the steaming mode, the main source of heat is the heating plate, and a small amount of water can be released through the water inlet 500, and the water spray device 400 cools down the surrounding cavity 100 and the panel. When the steam oven 1 is in the baking mode, the main source of heat is the heating tube 320. After cooking, the heating tube 320 and the inside of the cavity 100 are in a high temperature state. The heating tube 320, the heating fan 330 and the inner wall of the cavity 100 can be cooled down through the multiple water spray devices 400 on the upper side.
[0041] In a specific implementation, the water inlet 500 may be disposed at the lower portion of the rear wall 110 of the cavity 100 or at the lower portion of the side wall 140 of the cavity 100. Figure 1 As shown, the water inlet 500 is disposed at a lower position of the rear wall 110 .
[0042] In a specific implementation, the water spray device 400 is provided on both the front and rear sides of the cavity 100, and / or, the water spray device 400 is provided on both the left and right sides of the cavity 100. In addition, the multiple water spray devices 400 in the cavity 100 can be arranged symmetrically or asymmetrically according to the cooling requirements. For example, according to the positions of the heating tube 320, the heating plate 310 and the heat dissipation fan 220 in different models of steam ovens 1, the water spray device 400 is arranged on one side of the front and rear sides of the cavity 100, or on one side of the left and right sides.
[0043] like Figure 1 and Figure 2 As shown, four water spray devices 400 are provided in the cavity 100, and the four water spray devices 400 are respectively located at the four corners of the cavity 100; the water spray devices 400 are installed on the top wall 120 or the side wall 140 of the cavity 100. The water spray devices 400 are provided at the four corners of the cavity 100, so that the high-temperature gas can be cooled in different areas, thereby improving the flexibility of use and the cooling efficiency. Specifically, as Figure 1 As shown, water spray devices 400 are provided on the left and right sides of the rear wall 110, and water spray devices 400 are provided at positions close to the panels of the left and right side walls 140. The water spray devices 400 located inside the chamber can also be provided at positions of the left and right side walls 140 away from the panels.
[0044] Furthermore, the water spraying area of the water spraying device 400 is located between the heating pipe 320 and the heating plate 310, and between the rear wall 110 and the panel of the steam oven 1. The water spraying area of the water spraying device 400 can avoid the heating pipe 320, the heating plate 310 and the panel, avoiding the risks of uneven deformation of the inner wall of the cavity 100 due to heating, the breakage of the heating pipe 320 and the fragmentation of the door body, thereby improving the service life of the components of the whole machine.
[0045] Specifically, the water spray device 400 is a fixed nozzle or a rotatable nozzle. Further, in the steam oven 1, any one of the fixed nozzle and the rotatable nozzle, or a combination of the two, can be used.
[0046] In specific implementation, Figure 2 As shown, when the water spray device 400 is a fixed nozzle, the fixed nozzle is installed at an angle to the wall of the cavity 100, so that the water spray area of the fixed nozzle is located between the heating pipe 320 and the heating plate 310, and between the rear wall 110 and the panel of the steam oven 1. When a high-pressure nozzle with freely adjustable angle is used, the range of the water mist can be expanded and the heat dissipation efficiency can be increased.
[0047] The steam oven 1 further comprises a water pump, and the water inlet 500 and the water spray device 400 are both connected to the water pump. By using the existing water pump in the steam oven 1, the existing water in the steam oven 1 can be used for cooling, thereby simplifying the overall structure.
[0048] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
