Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to an air guide hood and a steam oven. Background Art

[0002] The steam in the steam-bake machine's inner pot is discharged directly into the heat dissipation duct through the exhaust pipe, and then discharged to the outside along with the flowing air in the heat dissipation duct. The condensed water remaining in the heat dissipation duct evaporates through the waste heat of the duct bottom plate, and the steam is discharged directly into the kitchen through the heat dissipation duct. The directly discharged steam has a high temperature and can easily scald the user, posing a safety hazard. It will also increase the humidity in the kitchen and reduce the user's experience.

[0003] To solve the problems of high temperature and high humidity caused by the steam discharge from the inner pot of the steam-oven oven, a steam condensing device is generally installed at the steam exhaust port of the steam-oven oven to effectively prevent the discharged steam from overheating. However, the air guide hood of the steam condensing device discharges steam unevenly during steam discharge, and the steam will be discharged at a certain point, causing the concentrated steam to condense at the discharge point to form water droplets that drip onto the machine and its surroundings, which can easily cause safety problems such as electric shock or fire due to water short-circuiting in surrounding electrical equipment.

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0032] When users use the steam function to cook food, the evaporator works first to generate heat to heat water to form steam. The steam then enters the cavity from the steam inlet through a pipe connection. The high-temperature steam in the cavity comes into contact with the food and transfers heat to the food, thereby achieving the effect of heating the food. The temperature of the steam will decrease after contacting the food. In order to continue to provide heat to the food, the high-temperature steam generated by the evaporator needs to be continuously input into the cavity while the lower temperature steam is discharged. The temperature of the discharged steam is basically 40-70℃. If it is discharged directly without any treatment, condensation water will form when it encounters cold air after discharge, forming water droplets that drip onto the machine and the floor, affecting the user experience; in severe cases, it will directly scald the user, posing a threat to user safety.

[0033] In order to solve the problems of high temperature and high humidity caused by steam discharge from the inner pot of a steam-oven oven, the prior art generally provides a steam condensing device at the steam exhaust port of the steam-oven oven. Although the discharged steam can be effectively prevented from being overheated, the air guide cover of the steam condensing device discharges the steam unevenly during steam discharge, and the steam will be discharged at a certain point, causing the concentrated steam to condense at the discharge point to form water droplets that drip onto the machine and its surroundings. If there are electrical equipment nearby, it is easy for water to short-circuit and cause safety problems such as electric shock or fire.

[0034] The embodiment of the utility model provides an air scoop and a steam oven, the air scoop comprising an air scoop seat and an air scoop cover snapped with the air scoop seat, the air scoop seat and the air scoop cover snapped together to form a cavity for storing and cooling steam, a steam inlet hole is arranged at one end of the bottom surface of the air scoop seat, a condensate outlet is arranged at the other end of the bottom surface, a plurality of flange holes are arranged on the top surface of the air scoop cover, the flange direction of the flange holes is downward, and the spacing of the flange holes decreases as the distance between the steam inlet hole and the flange holes increases; after the steam enters the air scoop, it goes upward, and due to the obstruction of the flange holes, the steam cannot be discharged directly from the flange holes, and the steam will be discharged from the flange holes of the air scoop cover only after filling the entire air scoop and exceeding the height of the flange, while the spacing between the flange holes close to the steam inlet hole is larger, and the spacing between the flange holes far from the steam inlet hole is smaller, thereby ensuring that the steam can be discharged evenly to the greatest extent, and effectively avoiding the electrical safety problem caused by condensate formed by concentrated steam discharge.

[0035] The air guide hood and the steam oven in the present application are described below through specific embodiments.

[0036] See also Figure 1 and Figure 2 , Figure 1 Schematic diagram A of a wind guide cover provided by an exemplary embodiment of the utility model. Figure 2 FIG. 1 is a schematic diagram B of a wind guide cover provided by an exemplary embodiment of the present invention; Figure 1 and Figure 2 The wind guide cover comprises: a wind guide cover seat 1 and a wind guide cover cover 2 buckled with the wind guide cover seat 1;

[0037] The air guide cover seat 1 and the air guide cover cover 2 are buckled together to form a cavity for storing and cooling steam;

[0038] A steam inlet hole 3 is provided at one end of the bottom surface of the air guide cover seat 1, and a condensed water outlet 4 is provided at the other end;

[0039] The top surface of the air guide cover 2 is provided with a plurality of flanged holes 5 ; the flanged direction of the flanged holes 5 is downward; and the distance between two adjacent flanged holes 5 decreases as the distance between the steam inlet hole 3 and the flanged holes 5 increases.

[0040] It should be noted that the air guide hood provided in this embodiment is applicable to equipment with steam exhaust, and can be specifically applicable to, but not limited to, steam ovens, electric steamers, pressure cookers, and steam sterilizers.

[0041] Specifically, the air guide cover seat 1 is fixed to the steam oven, and the steam outlet 11 of the steam oven is connected to the steam inlet hole 3 of the air guide cover seat 1. After the bolt holes on the buckling edge of the air guide cover cover 2 are aligned with the bolt holes on the buckling edge of the air guide cover seat 1, the air guide cover cover 2 is fixed to the air guide cover seat 1 by bolts to form a cavity for storing and cooling steam, and the condensate outlet 4 is connected to the water inlet of the steam oven with a hose to utilize the condensate circulation to generate steam and discharge it into the inner cavity of the steam oven again to heat food. When the steam is discharged from the flange hole 5, the spacing of the flange hole 5 decreases as the distance between the steam inlet hole 3 and the flange hole 5 increases, so that the discharged steam is more uniform.

[0042] It can be understood that the air guide hood provided in the present embodiment has a plurality of flange holes arranged on the top surface of the air guide hood cover. After the steam enters the air guide hood, it goes upwards. Due to the obstruction of the flange holes, the steam cannot be discharged directly from the flange holes. The steam will be discharged from the flange holes of the air guide hood cover only after it fills the entire air guide hood and exceeds the height of the flange. The flange holes close to the steam inlet hole are spaced relatively large, while the flange holes far from the steam inlet hole are spaced relatively small, thereby ensuring that the steam can be discharged evenly to the greatest extent possible, and effectively avoiding the electrical safety problems caused by condensed water formed by the concentrated discharge of steam.

[0043] In one embodiment, a groove 6 is provided on the bottom surface of the air guide cover seat 1 , and the groove 6 is connected to one end of the condensed water outlet 4 .

[0044] Specifically, the groove 6 set at one end of the condensate outlet 4 is connected to the condensate outlet 4, so that the condensate is collected in the groove 6 on the bottom surface of the air guide cover seat 1, and then flows into the water inlet of the steamer oven from the condensate outlet 4, so as to flow into the evaporator again for heating and producing steam.

[0045] It can be understood that the air guide cover provided in this embodiment collects water through the grooves, so that the condensed water is promptly sent to the steam oven for reuse.

[0046] In one embodiment, the steam inlet hole 3 is provided with an upward flange.

[0047] It should be noted that in order to prevent the condensed water in the air guide cover from flowing back into the steam oven, a flange is provided at the steam inlet hole 3, and the steam inlet hole 3 is higher than the condensed water outlet 4, so that the condensed water flows to the condensed water outlet 4 before crossing the flange of the steam inlet hole 3.

[0048] It can be understood that the air guide cover provided in this embodiment effectively prevents the backflow of condensed water by means of the upwardly turned edge of the steam inlet hole.

[0049] In one embodiment, an edge of the air guide cover seat 1 is provided with a water baffle 12 extending upward.

[0050] It should be noted that if the air guide cover seat 1 and the air guide cover cover 2 are not tightly fastened, the condensed water in the air guide cover will easily seep out from the fastening gap between the air guide cover seat 1 and the air guide cover cover 2. An upwardly extending water baffle 12 is provided at the edge of the air guide cover seat 1, which can effectively prevent the seeped condensed water from flowing out of the air guide cover.

[0051] In one embodiment, a gasket is provided on the buckling contact surface between the air scoop seat 1 and the air scoop cover 2 .

[0052] Specifically, a gasket is provided on the buckled contact surface between the air guide cover seat 1 and the air guide cover cover 2. The gasket may be a film or a plastic sheet, which is used to ensure the sealing effect between the air guide cover seat 1 and the air guide cover cover 2 so that condensation water is not easily leaked from the bottom surface; further, an annular groove may be provided on the buckled contact surface between the air guide cover seat 1 and the air guide cover cover 2, and a gasket is placed in the annular groove.

[0053] It can be understood that the air guide cover provided in this embodiment can effectively prevent condensed water in the air guide cover from leaking out from the bottom surface.

[0054] In one embodiment, the air guide cover further comprises:

[0055] The air duct cover outer cover 7 is provided with an air outlet 8 and an air inlet 9 ; the air duct cover outer cover 7 is placed above the air duct cover 2 and covers the air duct cover 2 ; the air duct cover 2 is placed between the air outlet 8 and the air inlet 9 .

[0056] It should be noted that a gap is left between the air guide cover outer cover 7 and the air guide cover cover 2 to facilitate ventilation and cooling.

[0057] See also Figure 3 , Figure 3 This is a schematic diagram of a steam oven provided by an exemplary embodiment of the present invention. Figure 3 , the air guide cover also includes:

[0058] Cooling fan 10; The cooling fan 10 is placed at the air inlet 9 of the air guide cover 7.

[0059] Specifically, the cooling fan 10 blows air from the air inlet 9 of the air scoop cover 7 to increase the wind speed between the air scoop cover 7 and the air scoop cover 2, accelerate the condensation of steam, and blow away the uniform steam discharged from the flange hole 5.

[0060] It can be understood that the air guide hood provided in this embodiment accelerates the cooling of the steam in the air guide hood through the cooling fan, and at the same time blows away the uniform steam discharged from the flange holes, thereby effectively avoiding the generation of condensed water outside the air guide hood.

[0061] In one embodiment, the flange height of the flange hole 5 of the air guide cover is set according to the model of the steam oven.

[0062] Specifically, the steam oven model determines the steam exhaust volume and steam exhaust speed, and the steam exhaust volume and steam exhaust speed determine the flange height of the flange hole 5. For example, if the steam exhaust volume is large, the flange height increases, and if the steam exhaust speed is fast, the flange height also needs to be increased.

[0063] In one embodiment, the flange height of the flange hole 5 of the air guide cover is set according to the model of the steam oven.

[0064] Specifically, the steam oven model determines the steam exhaust volume and steam exhaust speed, and the steam exhaust volume and steam exhaust speed determine the flange height of the flange hole 5. For example, if the steam exhaust volume is large, the flange height increases, and if the steam exhaust speed is fast, the flange height also needs to be increased.

[0065] In one embodiment, the bottom surface of the air guide cover seat 1 is an inclined plane, and the bottom surface on one side of the steam inlet hole 3 is higher than the bottom surface on one side of the condensate outlet 4.

[0066] It should be noted that after the condensed water is formed in the air guide cover, it falls to the bottom surface of the air guide cover seat 1, and the bottom surface is set as an inclined plane. The bottom surface on the side of the steam inlet hole 3 is higher than the bottom surface on the side of the condensed water outlet 4, so that the condensed water can flow to the condensed water outlet more easily.

[0067] Furthermore, the diameter of the flange hole 5 increases as the distance between the steam inlet hole and the flange hole increases.

[0068] It is understandable that the farther away from the steam inlet hole, the less steam there is. Therefore, the diameter of the flange hole 5 that is farther away from the steam inlet hole is larger to ensure uniform discharge of steam.
