Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to a head cover for a cooking utensil containing a bubble-breaking component. Background Art

[0002] In existing cooking utensils, when cooking food materials, heat and the like are easily accumulated at the head cover, and part of the hot air is discharged through the head cover. However, in this cooking method, once there is too much hot air and the airflow accumulates excessively, problems such as overflowing of the pot are likely to occur, affecting the cooking taste. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a head cover for a cooking utensil containing a bubble-breaking component, which breaks the cold air or cold air flow in the head cover through the bubble-breaking component, reduces the accumulation of hot air. At the same time, the cold air accelerates the circulation and reduces the surface temperature of the head cover, so that the temperature is lower when touching the head cover after opening, thereby reducing the probability of overflowing of the pot.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions.

[0005] A head cover for a cooking utensil containing a bubble-breaking component, including an inner cover, a panel, and an installation cavity formed by the inner cover and the panel. A cooling component is provided at the central position of the installation cavity, and the cooling component forms a working direction towards the panel;

[0006] A cooking cavity is arranged below the head cover. When the cooking cavity is in a cooking state, the hot air flow in the cooking cavity enters the inner cover, so that a first temperature is formed at the inner cover. Under set conditions, the cooling component is started to form a second temperature at the panel. The first temperature and the second temperature form a temperature difference, so that the bubbles formed by the hot air flow at the inner cover are broken, and the bubble-breaking is completed.

[0007] Further, a part of the installation cavity is concave towards the cooking cavity direction, and a guiding area is formed between the installation cavity and the cooling component.

[0008] Further, the height of the guiding area is between 15 - 20 mm, and the projection of the cooling component is within the guiding area.

[0009] Further, wind blocking ribs are provided on the panel, and the wind blocking ribs form a partially closed area around the cooling component.

[0010] Further, an anti-overflow port is provided on the panel. Along both sides of the anti-overflow port, arc-shaped wind blocking ribs and the panel form a symmetrically closed area outside the anti-overflow port.

[0011] Further, several flow dividing ribs are arranged within the closed area, and the flow dividing ribs form a flow dividing track from the cooling component towards the inner wall of the closed cavity.

[0012] Further, the flow dividing rib extends from the temperature reduction component to the inner wall of the closed cavity and abuts against it, forming an integrated structure.

[0013] Further, the height of the flow dividing rib is lower than that of the wind blocking rib, and the flow dividing rib is an arc-shaped rib structure.

[0014] Further, the temperature reduction component is a fan component assembled on the panel, and the motor of the fan component is fixed on the panel.

[0015] Further, the temperature difference formed by the first temperature and the second temperature is 5°C - 10°C.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, through the setting of the temperature reduction component, the temperature difference between the inside and the outside is realized. Inside the inner cover, the temperature reduction component is used to quickly disturb the flow and take away the temperature on the inner cover, so as to form a temperature difference on both sides of the inner cover, and then the water bubbles on the inner side of the inner cover are instantaneously broken when they come into contact.

[0018] In the present utility model, the guiding area is cleverly utilized to guide and gather bubbles and the like to the temperature reduction component, improving the aggregation property and reducing the dispersion, so that the bubble-breaking effect is better. At the same time, in the present utility model, a blocking rib or the like can also be added to the inner cover to make the wind flow more to this area, and then a large amount of heat can be taken away. The blocking rib gradually changes from low to high, and there is a gap of 5 - 10 mm when it reaches the inner cover at the high place, so that the wind is not sealed in this area.

Detailed Embodiments

[0025] The present utility model will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. It should be noted, however, that these embodiments are not limitations on the present utility model, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0026] Referring to the attached Figures 1-4 As shown, in this embodiment, the cooking utensil head cover 100 containing a bubble-breaking component includes an inner cover 110, a panel 120, and an installation cavity 130 formed by the inner cover 110 and the panel 120. A temperature-lowering component 140 is provided at the central position of the installation cavity 130, and the temperature-lowering component 140 forms a working direction towards the panel 120.

[0027] A cooking cavity 200 is provided below the head cover 100. When the cooking cavity 200 is in a cooking state, the hot air flow in the cooking cavity 200 enters the inner cover 110, causing a first temperature to be formed at the inner cover 110. Under set conditions, the temperature-lowering component 140 is activated to cause a second temperature to be formed at the panel 120. The first temperature and the second temperature form a temperature difference, causing the bubbles formed by the hot air flow at the inner cover 110 to be broken, completing the bubble-breaking.

[0028] When using the present utility model, when the general cooking temperature reaches 100 degrees, hot air is generated and moves towards the inner cover 110, causing the temperature at the inner cover to be approximately 100 degrees. Then, the temperature-lowering component 140 is activated. For example, a fan is selected to form the temperature-lowering component, and then the temperature at the panel 120 is reduced to approximately 5°C. Then, a temperature difference of 5°C to 10°C is formed in the installation cavity between the panel 120 and the inner cover 110. At this time, a fan is used to quickly turbulently flow the air inside the inner cover to take away the temperature on the inner cover, achieving a temperature difference on both sides of the inner cover, and then causing the water bubbles on the inner side of the inner cover to burst instantly when they contact the inner cover.

[0029] In this embodiment, in order to produce a better hot air aggregation effect, a part of the installation cavity 130 is concave towards the cooking cavity direction, forming a guiding area 150 with the temperature-lowering component 140. In this embodiment, the guiding area is formed, and thus the air flow and the like will also automatically flow into the lower guiding area 150, thereby improving the bubble-breaking efficiency.

[0030] Specifically, the height of the guiding area 150 is between 15 - 20 mm, and the temperature-lowering component 140 is projected into the guiding area 150. In this embodiment, the height of the guiding area is formed between the temperature-lowering component 140 and the lining plate 110. Selecting a height of 15 - 20 mm at this time mainly has the following effects:

[0031] 1) The fan (i.e., the cooling component) needs to maintain a space of 15 - 20 mm from the inner cover. At this time, the wind force is the maximum and there will be no resonance. The air intake and exhaust principle of the fan at this time is: sucking air in the middle and diffusing it around; maintaining this distance can achieve the maximum designed air volume of the fan, 2500 RPM.

[0032] 2) The inner cover 110 is recessed by 15 - 20 mm relative to the position of the fan, which can make the thickness of the upper cover not exceed 40 mm, achieving an aesthetic effect when viewed from the outside.

[0033] In order to ensure bubble breaking at the installation cavity, in this embodiment, a wind - blocking rib 121 is provided on the panel 120, and the wind - blocking rib 121 forms a partially enclosed area around the outer periphery of the cooling component 140. In this embodiment, the outer - ring wind - blocking rib can play a role in gathering wind and prevent it from spreading out.

[0034] In order to ensure normal avoidance, an anti - overflow port 160 is provided on the panel 120. Along both sides of the anti - overflow port 160, a symmetrically enclosed area outside the anti - overflow port 160 is formed between the arc - shaped wind - blocking rib 121 and the panel 120. In this embodiment, since the anti - overflow port 160 is generally set on the side, for the purpose of avoidance, the wind - blocking rib 121 bypasses it. Then, after the anti - overflow ports are connected, two enclosed areas similar to a butterfly shape are formed, and bubble breaking is carried out within this enclosed area.

[0035] In order to achieve better bubble breaking, several flow - dividing ribs 122 are provided in the enclosed area, and the flow - dividing ribs 122 form a flow - dividing trajectory from the cooling component 140 towards the inner wall of the enclosed cavity. In this embodiment, among several flow - dividing ribs 122, two adjacent flow - dividing ribs form an expanded - diameter area, thereby controlling the air volume in this area and preventing it from being blown away by the fan. This can increase the contact area with the inner cover and play an effect of taking away a large amount of heat.

[0036] In order to make the structure simple, the flow - dividing rib 122 extends from the cooling component 140 to the inner wall of the enclosed cavity and abuts against it, forming an integrated structure. In this embodiment, the flow - dividing rib and the wind - blocking rib form an integrated structure, which can play a role in strengthening the structure in terms of structure, so that any rib will not deform.

[0037] In this embodiment, the height of the flow - dividing rib 122 is lower than the height of the wind - blocking rib 121, and the flow - dividing rib 121 is an arc - shaped rib structure. In this embodiment, by using ribs with different heights, the wind is guided from high to low and then flows towards the fan area, while maximizing the air volume flowing to that area.

[0038] In order to ensure stability during assembly, the cooling component 140 is a fan assembly assembled on the panel, and the motor of the fan assembly is fixed on the panel 120.

[0039] In this embodiment, specifically, the head cover further includes a pot mouth rubber ring 180 and a lining cover 190. During assembly, the pot mouth rubber ring is placed on the annular rib position of the inner cover, and then the inner cover presses the pot mouth rubber ring according to the preset position, and then the inner cover is fixed to the inner cover again using screws. In cooperation with the cooling component in this embodiment, etc., the specific usage process is as follows:

[0040] After the cooking operation is started, after about 8 minutes, the cooling component is started and allowed to continue working, so that the head cover always achieves an effect of a 5-degree temperature difference between the top and bottom, in order to better break the bubbles.

[0041] In this embodiment, air cooling is utilized. Most of the heat is taken away by the fan-induced turbulence, achieving the effect of quickly cooling the surface of the object. It can be used in a variety of cooking utensils, such as an air fryer. At this time, a cooking cavity 200 is formed in the lower heat preservation cover, on which a head cover 100 is provided. By the rotation of the fan and the induced turbulence, the surrounding heat is taken away, cooling the motor and reducing the surface temperature of the surrounding components.

[0042] In the present utility model, a retaining rib 170, etc. is also added to the inner cover, so that the wind can flow too much into this area, and then a large amount of heat can be taken away. The retaining rib gradually changes from low to high, and there is a 5 - 10 mm gap when reaching the inner cover at the high position, so that the wind is not confined in this area.
