detailed description

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

As shown in Figures 1 and 2:

The steaming and roasting equipment with the functions of defogging the door glass and preventing dripping water according to the embodiment of the present invention. The steaming and roasting equipment is an all-in-one steaming and roasting machine, which includes an organic body 1, and a first fan 2 is provided inside the body 1. And steam heating plate 3, and the lower end of the body 1 is provided with an air cavity 4 isolated from the steaming and baking cavity 9, the steam heating plate 3 is located in the air cavity 4, and the air outlet end of the first fan 2 and the air cavity The air inlet 41 of 4 is connected; the door 5 on the body 1 is provided with an inner glass 6 and a middle glass 7 spaced apart from each other. A first air duct 8 is formed on the door 5 to communicate with the outside, and the air cavity 4 The air outlet 42 is in communication with the lower end of the first air duct 8. The steam heating plate 3 extends into the air cavity 4 from the upper end, and the bottom is pressed on the bottom surface of the air cavity 4. The air cavity 4 may be a sealed cavity at the bottom of the body 1, and the front and back sides of the air cavity 4 are provided respectively. There are the air inlet 41 and the air outlet 42; the first fan 2 may be a cross-flow fan, which is provided at the lower end of the rear side inside the body 1, and the air outlet end is connected to the air inlet 41 and the air cavity 4 The air outlet 42 is connected to the lower end of the first air duct 8 through the lower seat beam 51 of the door 5, and an air guide ring seat 10 is provided between the air outlet 42 of the air cavity 4 and the lower seat beam 51 of the door 5.

The working principle of the steaming and roasting device of the present invention is: when the steaming and roasting device is operating in the steaming mode, the steam heating plate 3 is heated by the water on the steam heating plate 3 to generate steam under the action of an electric heating pipe, thereby heating food. Cooking; at the same time, the bottom of the steam heating plate 3 also generates excess heat, which is dissipated into the air in the air cavity 4 and forms hot air under the action of the first fan 2 and flows from the air cavity 4 to the inner glass 6 and the middle layer Inside the first air duct 8 between the glass 7 (specifically: the hot air flows into the first air duct 8 through the air cavity 4, the air guide ring seat 10 and the lower seat cross beam 51 in this order.), The inner glass 6 is under the action of the hot air The outer surface temperature rises. In this way, the steaming and roasting device of the present invention reduces the temperature difference between the inner and outer surfaces of the inner glass 6 by making full use of the residual heat at the bottom of the steam heating plate 3, thereby achieving defogging of the glass surface and no water droplets hanging on the surface, which greatly improves (glass) The visibility of the window of the door 5 is more convenient to use, and avoids the problem of cabinet damage caused by water droplets flowing out when the door 5 is opened after cooking. The temperature of the cabinet is reduced, thereby increasing the service life of the steaming and baking machine and the cabinet, and The special water receiving tank of the traditional steaming and roasting equipment is removed, which avoids the problem of mosquitoes and bacteria breeding due to the accumulated water in the water receiving tank, which is hygienic and safe.

In addition, the steam heating plate 3 is provided with a second air duct 31, and an installation direction of the second air duct 31 is consistent with a wind flow direction of the air cavity 4. In this way, the utilization of excess heat of the steam heating plate 3 and the formation of hot air can be effectively improved, and the effect of protecting the door glass from defogging and dripping water can be further ensured.

As a preferred solution of the present invention, a second fan 11 is further provided inside the body 1, and a third air duct 12 isolated from the steaming and baking cavity 9 is provided at the upper end of the body 1. The air inlet is in communication with the air outlet of the second fan 11. The air outlet extends to the front side of the body 1 and faces the air outlet of the first air duct 8 on the upper end face of the door 5. Wherein, the third air duct 12 may be a funnel-shaped passage with a large air inlet and a small air outlet. The second fan 11 is provided at the upper end of the rear side of the body 1 and the air outlet end is connected to the third air duct 12. Inlet connection. When the steaming and baking integrated machine exhausts the hot air from the upper end of the door 5 through the first air duct 8 through the first fan 2, the second fan 11 blows out the steam from the third air duct 12 to exhaust the hot air and steam out of the body 1 together. In addition, it prevents hot air from flowing back into the upper end of the first air duct 8 and affects the hot air fluidity and heat exchange effect in the first air duct 8, and the door glass has a more stable and reliable performance of defogging and non-hanging water droplets.

Of course, the steaming and roasting device with the functions of defogging the door glass and preventing dripping water according to the present invention may also be an electric steam box or an electric steam oven.

The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, a number of improvements and retouches can be made. These improvements and retouches also depend on It is the protection scope of the present invention.
