Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and particularly relates to an air fryer. Background Art

[0002] Air fryers are widely praised by consumers in the market for their ability to achieve a tender roasted taste for ingredients. In order to enhance the user experience, some air fryers on the market are equipped with a viewing window to visualize the cooking process. Existing viewing window structures are generally made of glass and the outer side of the viewing window is usually in direct contact with the indoor air. When the cooking temperature of the air fryer is low, for example, the temperature in the cooking chamber reaches 60℃-95℃, as the tender roasting cooking proceeds, the water vapor in the fryer reaches saturation, and there is a certain temperature difference between the inside and outside of the viewing window. The water vapor on the inside of the viewing window will condense on the inner surface of the viewing window. Most of the water droplets condensed on the inner wall of the viewing glass are in a partially wetted state, and the surface tension between them and the glass is relatively strong. The condensed water droplets are in a steady state (or metastable state) and are not easy to slide on the viewing glass. When the viewing glass condenses more water droplets, the condensed water mist will scatter the light, resulting in the attenuation of the light intensity, the deflection of the light and the reduction of the contrast, thereby affecting the visual effect.

[0003] In order to improve the impact of condensed water vapor on the visual effect, the existing technology usually sprays a hydrophobic coating on the visual glass, or lays a heating wire inside the visual glass. However, the hydrophobic coating generally has poor high temperature resistance, is easy to fall off from the visual glass, has a short-lasting effect, and is complicated to process; the solution of laying a metal heating wire inside the glass is costly and has a complex structure. Utility Model Content

[0004] The utility model provides an air fryer, which solves the problem in the prior art that the visual effect is deteriorated due to the visual window being affected by condensed water drops on the basis of reducing costs and simplifying processes, and realizes the improvement of the visualization effect.

[0005] The technical solution adopted by the utility model is:

[0006] The utility model provides an air fryer, comprising a body and a reflective cover arranged in the body, wherein the reflective cover divides the internal space of the body into an installation cavity and a cooking cavity located below the installation cavity, a motor is arranged in the installation cavity, a heating tube and a hot fan are arranged in the cooking cavity, the body is provided with a visual window located at the front side above the cooking cavity and inclined relative to a horizontal plane, the air fryer also comprises a condenser, the condenser comprises an air intake section and a condensation section which are connected in sequence, the air intake section is connected with the cooking cavity and extends upward into the installation cavity, the installation cavity is connected with the outside and is provided with a cold fan inside, the condensation section extends downward in the installation cavity, and an outlet of the condensation section is located at the upper end of the inner wall surface of the visual window.

[0007] The air fryer provided by the utility model is provided with a viewing window inclined relative to a horizontal plane, so that the user can observe the cooking progress of the ingredients during the processing, thereby improving the user experience; the inclined viewing window can reduce the adhesion of condensed water droplets when condensed water is formed on the inner surface; by providing a condenser tube, the condenser tube comprises an air intake section and a condensation section which are connected in sequence; the air intake section is connected to the cooking cavity and extends upward to the installation cavity, so that when the water vapor in the cooking cavity is saturated, it can enter through the air intake section and then flow to the condensation section; since the condensation section extends downward in the installation cavity, the The outlet is located at the upper end of the inner wall surface of the visual window, the installation cavity is connected to the outside and is provided with a cooling fan inside, therefore, the temperature of the installation cavity is lower than that of the cooking cavity, and the operation of the cooling fan forms a cold wind flow in the installation cavity, cooling the condensation section, so that the water vapor entering the condensation section is condensed into liquid, and the liquid flows from top to bottom to the upper end of the inner wall surface of the visual window, and then washes the water droplets formed on the inner wall surface of the visual window, forming a moving water film on the inner wall surface of the visual window, as the air intake section continuously collects steam, the condensation effect of the condensation section on the cold wind flow path continuously occurs, and the moving water film on the inner surface of the visual window will be continuously formed. The moving water film will cause the water droplets on the inner wall of the visual window that were originally difficult to move to flow, so that a layer of water film that is close to parallel to the interface of the visual window is formed on the inner side of the visual window, and the parallel water film has a greatly reduced light deflection effect compared with the water droplets, thereby effectively improving the visual effect. By setting a condenser, the steam generated in the cooking cavity can be rationally utilized. Compared with methods such as spraying a hydrophobic coating on the viewing window and setting a heating wire, the production and processing technology can be reduced, the cost of the air fryer can be reduced, and the structure can be simplified. Moreover, the condenser is fixed in the installation cavity and is not easily damaged or dropped, and the improvement of the visual effect of the viewing window is more lasting and effective.

[0008] In a preferred embodiment, the inner diameter of the condensation section gradually decreases from the inlet to the outlet.

[0009] By gradually reducing the inner diameter of the condensation section from the inlet to the outlet, the water droplets formed after the steam condenses in the condensation section can have a convergence effect toward the outlet direction, thereby accelerating the flow of condensed water, increasing the flow rate and efficiency of condensed water flushing the viewing window, and preventing condensed water from staying in the condensation section, quickly forming a moving water film on the inner wall surface of the viewing window, thereby improving the visual effect.

[0010] In a preferred embodiment, the outlet of the air inlet section gradually shrinks and docks with the inlet of the condensation section.

[0011] By gradually shrinking the outlet of the air inlet section and docking it with the inlet of the condensation section, the shrinking air inlet section gathers steam, accelerating the steam to enter the condensation section, thereby accelerating the formation of condensed water, and quickly forming a moving water film on the inner wall of the visual window, thereby improving the visual effect.

[0012] In a preferred embodiment, a guide groove with a gradually decreasing groove width is provided at the outlet of the condenser.

[0013] By arranging a guide groove with a gradually decreasing groove width at the outlet of the condenser, the diversion and gathering effects are achieved. When the condensed water flowing out of the outlet of the condenser enters the guide groove, the condensed water is guided by the guide groove and gathered to the outlet of the guide groove to form a water flow. By arranging multiple guide grooves, the water flow rate can be accelerated and the degree of water film formed on the visual window can be increased, thereby improving the stability of the moving water film, flushing away water droplets attached to multiple parts of the visual window, and improving the visual effect.

[0014] In a preferred embodiment, a plurality of branches arranged in parallel are provided at the outlet of the condenser pipe, a plurality of guide grooves are provided, and the number and position of the branches and the guide grooves correspond one to one;

[0015] By arranging multiple branches at the outlet of the condenser and correspondingly arranging guide grooves, multiple water flows can be diverted along the width direction of the viewing window and the multiple water flows can be simultaneously directed to more parts of the viewing window, thereby fully flushing the viewing window and comprehensively improving the visual effect.

[0016] In a preferred embodiment, the guide grooves are arranged in multiple rows along the water flow direction, and the number of guide grooves in each row gradually increases.

[0017] By arranging the diversion grooves into multiple rows, further diversion and diversion can be achieved step by step and layer by layer, which can increase the degree to which the water flow forms a water film, improve the flushing effect on the visual window, and achieve comprehensive visualization.

[0018] In a preferred embodiment, the guide groove is formed by a curved surface that is recessed in a direction away from the viewing window.

[0019] The guide groove is formed by a curved surface that is concave away from the visual window, for example, a water drop shape or a hemispherical surface. The flow velocity in places with a larger curvature of the curved surface will accelerate the flow of condensed water, and the pressure is small where the flow velocity is large. The atmospheric pressure will further rely on the surface of the guide groove. During the movement, the water flow will be spread into a film under the action of the guide groove, thereby improving the diversion and diversion effects.

[0020] In a preferred embodiment, the hot fan and the heating tube are arranged from top to bottom at the upper part of the cooking cavity, and the inlet of the air intake section is located on the side of the heating tube.

[0021] By arranging the inlet of the air intake section on the side of the heating tube, the temperature at the inlet of the air intake section is effectively increased, thereby preventing steam from condensing at the inlet of the air intake section, allowing the steam to smoothly pass through the air intake section and flow to the condensation section, and then condense into water flow in the condensation section, thereby flushing the visual window. Therefore, effective flushing is achieved, while preventing condensed water from dripping onto the food in the cooking chamber, thereby avoiding affecting the taste of the food.

[0022] In a preferred embodiment, the angle of the visible window relative to the horizontal plane is A, which satisfies: 45°≤A≤60°.

[0023] When the angle between the viewing window and the horizontal plane is between 45° and 60°, the water film reliably flows inside the viewing window under the action of gravity and the surface tension between the viewing window and the water flow. Moreover, in this angle range, the viewing angle is sufficient and the steam fully swirls in the cooking cavity, while the efficiency of guiding the water vapor into the inlet of the air intake section is high. If A is too small, less than 45°, the flow rate of the water flow may weaken, and the flushing effect on the water droplets attached to the inside of the viewing window is poor. If A is too large, greater than 60°, it is not conducive to the user to observe the inside of the cooking cavity from top to bottom, and the viewing angle is poor.

[0024] In a preferred embodiment, the inlet inner diameter of the condensation section is d1, and the outlet inner diameter of the condensation section is d2, satisfying: 8mm≤d1≤12mm, 1mm≤d2≤3mm.

[0025] By setting the inlet inner diameter of the condensation section at 8mm-12mm, the speed and amount of water vapor entering the condensation section can be guaranteed while reasonable space arrangement and utilization are provided. The outlet inner diameter of the condensation section is 1mm-3mm, which plays a role in gathering flow, gathering droplets into flow, and then making the condensed water flow out in streams at the outlet of the condensation section, so as to achieve the purpose of effectively flushing the visual window and facilitate the formation of a dynamic water film on the visual window. At the same time, it avoids the outlet being less than 1mm, which affects the discharge of condensed water, thereby ensuring the discharge efficiency.

[0026] In a preferred embodiment, a water storage area is provided at the bottom of the cooking cavity, and the air fryer also includes a reflux pipe, one end of which is arranged at the bottom end of the inner wall of the viewing window to collect water flowing down the viewing window, and the other end of the reflux pipe is connected to the water storage area.

[0027] By providing a water storage area at the bottom of the cooking cavity, the water flowing down the viewing window is recycled, thereby improving the water utilization rate of the air fryer and preventing condensed water from excessively gathering on the viewing window to form water droplets that drip onto the food surface and affect the taste. By providing a water storage area, such as providing a water storage tank or a steam generating device on the bottom wall of the cooking cavity, the water in the water storage area can be further evaporated during the cooking process of the food, and the evaporation of the water flow heats the food with water vapor or prevents the food from losing too much water and causing a dry taste, thereby improving the taste and cooking efficiency.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] like Figure 1As shown, the utility model provides an air fryer, comprising a body 10 and a reflector 20 arranged in the body 10, the reflector 20 divides the internal space of the body 10 into an installation cavity 11 and a cooking cavity 12 located below the installation cavity 11, a motor 13 is arranged in the installation cavity 11, a heating pipe 15 and a hot fan 16 are arranged in the cooking cavity 12, the body 10 is provided with a visual window 17 located at the front side above the cooking cavity 12 and inclined relative to the horizontal plane, the air fryer also includes a condenser 30, the condenser 30 includes an air intake section 31 and a condensation section 32 connected in sequence, the air intake section 31 is connected to the cooking cavity 12 and extends upward to the installation cavity 11, the installation cavity 11 is connected to the outside and is provided with a cold fan 14, the condensation section 32 extends downward in the installation cavity 11, and the outlet of the condensation section 32 is located at the upper end of the inner wall surface of the visual window 17. The visual window 17 can be selected from transparent glass or transparent plastic.

[0042] It should be noted that the condenser 30 can be a flexible tube. By setting a positioning column in the installation cavity 11, the middle part of the flexible tube is raised and positioned at the highest point relative to the two ends of the flexible tube, and the air intake section 31 and the condensation section 32 are integrally connected and respectively located on both sides of the highest point. Of course, in practice, the condenser 30 can be a bent hard tube, and the two ends of the hard tube are fixed in the installation cavity 11, and the bend is located at the highest point to divide the air intake section 31 and the condensation section 32 that are integrally connected. In addition, the condenser 30 optionally includes a split air intake section 31 and a condensation section 32 that are docked, and the docking position of the air intake section 31 and the condensation section 32 is located at the highest point.

[0043] In addition, it should be noted that the shape of the air intake section 31 can be selected to extend gradually from the inlet to the outlet, or to extend vertically upward and then gradually extend upward. Similarly, the condensation section 32 can be selected to extend gradually from the inlet to the outlet, or to extend gradually upward and then vertically extend downward.

[0044] like Figure 1 As shown, the air fryer is a flip-top type, the machine body 10 includes a machine head and a machine base with a pot body installed, the machine head is hinged at the rear end of the machine base and flips relative to the machine base, the reflector is installed on the machine head and encloses the pot body to form a cooking cavity, and the visual window is installed on the front side of the machine head. Of course, in fact, the air fryer can also be selected as a drawer type, the machine body is provided with a drawer-type pot body, which is pulled out from the front side of the installation cavity, and the visual window is installed above the opening on the front side of the machine body.

[0045] The air fryer provided by the utility model is provided with a viewing window 17 inclined relative to the horizontal plane, so that the user can observe the cooking progress of the ingredients during the processing, thereby improving the user experience. The inclined viewing window 17 can reduce the adhesion of condensed water droplets when condensed water is formed on the inner surface. By providing a condenser tube 30, the condenser tube 30 includes an air intake section 31 and a condensation section 32 that are connected in sequence. The air intake section 31 is connected to the cooking cavity 12 and extends upward to the installation cavity 11, so that when the water vapor in the cooking cavity 12 is saturated, it can enter through the air intake section 31 and then flow to the condensation section 32; because the condensation section 32 extends downward in the installation cavity 11, the outlet of the condensation section 32 is located at the viewing window 17. At the upper end of the inner wall surface of the window 17, the installation cavity 11 is connected to the outside and a cooling fan 14 is arranged inside. Therefore, the temperature of the installation cavity 11 is lower than that of the cooking cavity 12, and the operation of the cooling fan 14 forms a cold air flow in the installation cavity 11, which cools the condensation section 32, so that the water vapor entering the condensation section 32 is condensed into liquid, and the liquid flows from top to bottom to the upper end of the inner wall surface of the visual window 17, and then washes the water droplets formed on the inner wall surface of the visual window 17, forming a moving water film on the inner wall surface of the visual window 17. As the air intake section 31 continuously collects steam, the condensation effect of the condensation section 32 on the cold air flow path continues to occur, and the moving water film on the inner surface of the visual window 17 will be continuously formed. The moving water film will cause the water droplets on the inner wall of the visual window 17 that were originally difficult to move to flow, so that a layer of water film that is close to the interface of the visual window 17 is formed on the inner side of the visual window 17. Compared with the water droplets, the parallel water film greatly reduces the deflection effect of light, thereby effectively improving the visual effect. By setting the condenser 30, the steam generated in the cooking cavity 12 is rationally utilized. Compared with spraying a hydrophobic coating on the viewing window 17 and setting a heating wire, the production and processing technology is reduced, the cost of the air fryer is reduced, and the structure is simplified. Moreover, the condenser 30 is fixed in the installation cavity 11 and is not easily damaged or dropped, and the improvement of the visual effect of the viewing window 17 is more lasting and effective.

[0046] In a preferred embodiment, Figure 2 As shown, the inner diameter of the condensation section 32 gradually decreases from the inlet to the outlet.

[0047] By gradually reducing the inner diameter of the condensation section 32 from the inlet to the outlet, the water droplets formed after the steam condenses in the condensation section 32 can have a convergence effect toward the outlet direction, thereby accelerating the flow of condensed water, increasing the flow rate and efficiency of condensed water flushing the visual window 17, and preventing the condensed water from staying in the condensation section 32, quickly forming a moving water film on the inner wall surface of the visual window 17, thereby improving the visual effect.

[0048] In a preferred embodiment, the outlet of the air inlet section 31 gradually shrinks and docks with the inlet of the condensation section 32. Figure 2As shown, the inner diameter of the connection part between the air inlet end and the condensation section 32 is gradually reduced and integrally formed. Of course, in another preferred implementation example, the air inlet section 31 and the condensation section 32 are connected separately, and a step is formed at the connection part.

[0049] By gradually shrinking the outlet of the air inlet section 31 and docking it with the inlet of the condensation section 32, the shrinking air inlet section 31 gathers steam, accelerating the steam to enter the condensation section 32, thereby accelerating the formation of condensed water, and quickly forming a moving water film on the inner wall of the visible window 17, thereby improving the visual effect.

[0050] In a preferred embodiment, Figure 1-3 As shown, a guide groove 40 with a gradually decreasing groove width is provided at the outlet of the condenser 30. Preferably, the guide groove 40 is formed by a curved surface that is concave away from the viewing window 17, such as Figure 3 As shown, multiple rows of guide grooves 40 are provided along the water flow direction, and the number of guide grooves 40 in each row gradually increases.

[0051] By providing a guide groove 40 with a gradually decreasing groove width at the outlet of the condenser 30, the guide and gathering functions are realized. When the condensed water flowing out of the outlet of the condenser 30 enters the guide groove 40, the condensed water is guided by the guide groove 40 and gathered to the outlet of the guide groove 40 to form a stream of water. By arranging multiple guide grooves 40, the water flow rate can be accelerated and the degree of water film formed on the visual window 17 can be increased, thereby improving the stability of the moving water film, flushing away the water droplets attached to multiple parts of the visual window 17, and improving the visual effect. The guide groove 40 is formed by a curved surface that is concave away from the visual window 17, for example, Figure 5 The surface shown is a hemispherical surface, such as Figure 6 As shown, the curved surface is similar to a water drop shape. The flow velocity in places with a larger curvature of the curved surface will accelerate the flow of condensed water, and the pressure is small in places with a large flow velocity. The atmospheric pressure will further rely on the surface of the guide groove 40. During the movement, the water flow will be flattened into a film under the action of the guide groove 40, thereby improving the diversion and diversion effects. By setting the guide groove 40 in multiple rows, further diversion and diversion can be achieved step by step and layer by layer, which can improve the degree to which the water flow is spread into a water film, improve the flushing effect on the visual window 17, and achieve comprehensive visualization.

[0052] In another preferred embodiment, Figure 4 As shown, a plurality of branches 33 arranged in parallel are provided at the outlet of the condenser 30, and a plurality of guide grooves 40 are provided, and the number and position of the branches 33 and the guide grooves 40 correspond one to one;

[0053] By setting multiple branches 33 at the outlet of the condenser 30 and correspondingly setting the guide grooves 40, multiple water flows can be diverted along the width direction of the visual window 17 and the multiple water flows can be synchronously guided to more parts of the visual window 17, thereby fully flushing the visual window 17 and comprehensively improving the visual effect.

[0054] In a preferred embodiment, Figure 1 As shown, the hot fan 16 and the heating tube 15 are arranged from top to bottom at the upper part of the cooking cavity 12 , and the inlet of the air intake section 31 is located on the side of the heating tube 15 .

[0055] By arranging the inlet of the air intake section 31 on the side of the heating tube 15, the temperature at the inlet of the air intake section 31 is effectively increased, thereby preventing the steam from condensing at the inlet of the air intake section 31, so that the steam smoothly passes through the air intake section 31 and flows to the condensation section 32, and then condenses into water flow in the condensation section 32, thereby flushing the visual window 17. Therefore, effective flushing is achieved, and at the same time, the condensed water is prevented from dripping onto the food in the cooking cavity 12, thereby avoiding affecting the taste of the food.

[0056] In a preferred embodiment, the angle of the visual window 17 relative to the horizontal plane is A, which satisfies: 45°≤A≤60°. A can be selected as 45°, 50°, 55° or 60°. The inlet inner diameter of the condensation section 32 is d1, and the outlet inner diameter of the condensation section 32 is d2, which satisfies: 8mm≤d1≤12mm, 1mm≤d2≤3mm.

[0057] When the angle between the visual window 17 and the horizontal plane is between 45° and 60°, the water film reliably flows inside the visual window 17 under the action of gravity and the surface tension between the visual window 17 and the water flow. Moreover, in this angle range, the visual angle is sufficient and the steam fully swirls in the cooking cavity 12, and the efficiency of guiding the water vapor into the inlet of the air inlet section 31 is high. If A is too small and less than 45°, the flow rate of the water flow may be weakened, and the flushing effect on the water droplets attached to the inside of the visual window 17 is not good. If A is too large and greater than 60°, it is not conducive to the user to observe the inside of the cooking cavity 12 from top to bottom, and the visual angle is not good.

[0058] By setting the inlet inner diameter of the condensation section 32 at 8mm-12mm, the speed and amount of water vapor entering the condensation section 32 can be guaranteed while reasonable space arrangement and utilization are provided. The outlet inner diameter of the condensation section 32 is 1mm-3mm, which plays a role in gathering flow, gathering droplets into flow, and then making the condensed water flow out in streams at the outlet of the condensation section 32, so as to achieve the purpose of effectively flushing the visual window 17 and facilitate the formation of a dynamic water film on the visual window 17, while avoiding the outlet being less than 1mm to affect the discharge of condensed water, thereby ensuring the discharge efficiency.

[0059] like Figure 1As shown, in a preferred embodiment, a water storage area is provided at the bottom of the cooking cavity 12, and the air fryer further includes a reflux pipe 50, one end of which is provided at the bottom end of the inner wall of the visual window 17 to collect water flowing down the visual window 17, and the other end of the reflux pipe 50 is connected to the water storage area. Preferably, a steam generating device 60 is provided at the bottom of the cooking cavity 12 to form a water storage area, and the water in the water storage area can be further evaporated during the cooking process of the food, and the evaporation of the water flow heats the food with water vapor or prevents the food from losing too much water and causing a dry taste, thereby improving the taste and the cooking efficiency.

[0060] Of course, a water storage tank may also be directly provided on the bottom wall of the cooking cavity 12 to form a water storage area.

[0061] By providing a water storage area at the bottom of the cooking cavity 12, the water flowing down the viewing window 17 is recycled, thereby improving the water utilization rate of the air fryer, and at the same time preventing condensed water from excessively gathering into water droplets on the viewing window 17 and dripping on the food surface to affect the taste.
