Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly designs a double-chamber air fryer. Background Art

[0002] An air fryer is a kitchen cooking appliance that can use heated air to replace "deep frying". Its main principle is to utilize the high-speed air circulation technology, allowing the rapidly circulating hot air to replace the hot oil in a traditional frying pan, so that the food in the air fryer is cooked. At the same time, the hot air generated can also blow away the moisture on the surface of the food, forming a crispy surface on the food and locking the moisture inside the ingredients, thus enabling the ingredients in the air fryer to achieve a cooking effect similar to deep frying.

[0003] In the existing air fryer, a heating device, a driving motor and a blower are all arranged at the top of the cooking cavity in the pot body. Its working principle is that the motor drives the blower to generate an air flow, and the air flow heats the food in the pot body with the heat generated by the heating device. However, with this setting method, the motor at the top is also affected by the heating device, and the motor cannot work for a long time in a high-temperature environment, which will increase the failure rate of the motor and reduce the working life of the motor at the same time. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a double-chamber air fryer, in which the DC motor is arranged outside the heating cavity to avoid the heating device having a great influence on the DC motor.

[0005] In order to achieve the above purpose, the basic scheme of the utility model is as follows:

[0006] A double-chamber air fryer includes a body, an upper cavity group and a lower cavity group which are arranged up and down in the height direction in the body. Baking cavities are formed inside the upper cavity group and the lower cavity group. A heating device is arranged at the top of the baking cavity. An air inlet assembly is arranged on one side outside the upper cavity group and the lower cavity group. The upper cavity group and the lower cavity group are respectively connected with a pressurizing air duct to the air inlet assembly on one side of them. A pressurizing cavity is formed in the pressurizing air duct, and two ends of the pressurizing cavity are respectively connected with the air inlet assembly and the baking cavity; the air inlet assembly is a DC motor fan.

[0007] Compared with the prior art, the double-chamber air fryer of the present application has the following beneficial effects:

[0008] The dual-chamber air fryer of the present application sets the air intake component on the outer side of the upper chamber group and the lower chamber group. At the same time, a DC motor fan is used as the air intake component. The DC motor has a low cost. The DC motor and the fan are connected as a whole. The length of its fan blades is relatively short compared to traditional 5-blade or 6-blade fans, taking up less space and having relatively low rotational noise. The arrangement position of the DC motor is such that, compared to the traditional scheme of arranging it at the top of the heating device, its working environment temperature is low, and the overall service life is longer, allowing the product to continuously work for a longer time without high-temperature failures.

[0009] Among them, the setting of the pressurizing chamber enables the air flow generated by the air intake component to flow powerfully towards the baking chamber after passing through the pressurizing chamber, that is, the air flow velocity increases, enabling the food in the baking chamber to be heated quickly.

[0010] Preferably, the pressurizing chamber is provided with an air inlet and an air outlet. The air inlet of the pressurizing chamber is vertically connected to the air intake component, and the air outlet of the pressurizing chamber is connected to the baking chamber of the upper chamber group or the baking chamber of the lower chamber group.

[0011] Beneficial effects: The wind generated by the DC motor fan is a lateral wind with centrifugal force. By vertically connecting and setting the pressurizing chamber, the centrifugal force of the lateral wind is reduced, the turbulence is reduced, and the baking effect is ensured. The wind generated by the DC motor can accumulate in the pressurizing chamber and then, under continuous pressure, uniformly flow along the air outlet towards the position of the heating device.

[0012] Preferably, the cross-sectional area of the pressurizing air duct where the air inlet plane is located is larger than the cross-sectional area of the air outlet.

[0013] Preferably, the cross-sectional area of the air outlet is gradually reduced from the inside to the outside.

[0014] Beneficial effects: The air inlet and air outlet of the pressurizing chamber are set using Bernoulli's principle to increase the air flow velocity at the air outlet and provide a powerful air flow for food baking.

[0015] Preferably, the pressurizing air duct includes a duct body and a duct cover covering the duct body. At least one air guiding plate is provided at the bottom of the duct cover. The air guiding plate is located at the air outlet. The direction of the air guiding plate is the same as the air outlet direction of the air outlet, and the air guiding plates are evenly distributed with equal gaps between them.

[0016] Beneficial effects: The setting of the air guiding plate is to prevent the wind from concentrating in the center of the baking chamber, but instead to deflect the wind appropriately towards the periphery of the baking chamber, making the baking more uniform and the food baking effect better.

[0017] Preferably, machine covers are provided at the tops of both the upper chamber group and the lower chamber group. The machine cover includes a movement cover and a movement inner cover. The movement cover is located above the movement inner cover, and both the movement cover and the movement inner cover are fixedly connected to the duct cover.

[0018] Preferably, a wind shield strip is formed by the downward depression of the inner cover of the movement, and the wind shield strip is arranged horizontally facing the air outlet.

[0019] Preferably, the wind shield strip includes a first wind shield strip and a second wind shield strip. The first wind shield strip is arranged close to the air outlet, the second wind shield strip is arranged far from the air outlet, and the first wind shield strip is located between the second wind shield strip and the air outlet.

[0020] Preferably, the height of the first wind shield strip concave downward relative to the inner cover of the movement is less than the height of the second wind shield strip concave downward relative to the inner cover of the movement.

[0021] Preferably, ventilation gaps are reserved between both sides of the first wind shield strip and the inner cover of the movement; ventilation gaps are reserved between both sides of the second wind shield strip and the inner cover of the movement.

[0022] Beneficial effects: The arrangement of the first wind shield strip and the second wind shield strip enables the air flow to turn downward along the first wind shield strip and the second wind shield strip after coming out of the air outlet, making the food baking more uniform.

[0030] The following is further detailed through specific embodiments:

[0031] The reference numerals in the accompanying drawings of the specification include: the body 1, the upper cavity group 2, the lower cavity group 3, the baking cavity 4, the heating device 5, the air inlet assembly 6, the pressurizing air duct 7, the pressurizing cavity 8, the air inlet 9, the air outlet 10, the air duct body 11, the air duct cover 12, the air guiding plate 13, the movement cover 14, the inner movement cover 15, the first wind blocking strip 16, the second wind blocking strip 17, and the gap 18.

[0032] As shown in the Figure 1-7 accompanying drawings, this embodiment shows a double - cavity air fryer, which includes a body 1 and an upper cavity group 2 and a lower cavity group 3 that are arranged up and down along the height direction inside the body 1. Baking cavities 4 are formed inside both the upper cavity group 2 and the lower cavity group 3, and a heating device 5 is arranged at the top of the baking cavity 4. Air inlet assemblies 6 are arranged on one side outside both the upper cavity group 2 and the lower cavity group 3. The upper cavity group 2 and the lower cavity group 3 are respectively connected to the air inlet assemblies 6 on their respective sides by pressurizing air ducts 7. A pressurizing cavity 8 is formed inside the pressurizing air duct 7, and both ends of the pressurizing cavity 8 are respectively connected to the air inlet assembly 6 and the baking cavity 4. Among them, the air inlet assembly 6 is a DC motor fan.

[0033] Specifically, as shown in Figure 2 Figure 3, the air inlet assembly 6 is arranged at the rear side of the upper cavity group 2 or the lower cavity group 3, and the pressurizing cavity 8 is respectively connected to the top of the rear end of the baking cavity 4 and the top of the air inlet assembly 6.

[0034] The working principle of the double - cavity air fryer in this embodiment is as follows: After placing the food to be heated in the baking cavity 4, the DC motor fan starts, generates air flow and sends it into the pressurizing air duct 7. After the air flow is pressurized by the pressurizing air duct 7, it flows into the baking cavity 4. At the same time, the heating device 5 at the top of the baking cavity 4 works to generate heat, and the heat generated by the heating device 5 is carried to the surface of the food in the baking cavity 4 through the above - mentioned air flow to heat the food.

[0035] In this embodiment, by arranging the air inlet assembly 6 at the rear side of the upper cavity group 2 or the lower cavity group 3, it is possible to avoid the heat generated by the heating device 5 directly acting on the air inlet assembly 6, reduce the temperature of the working environment of the air inlet assembly 6, thereby reducing the working failure rate of the air inlet assembly 6 and extending the working life of the air inlet assembly 6.

[0036] At the same time, in this embodiment, by arranging the pressurizing cavity 8 to connect the baking cavity 4 and the air inlet assembly 6, a continuous and rapid air flow is brought to the baked food, improving the heating efficiency.

[0037] As shown in Figure 5As shown in Figure 6, an air inlet 9 and an air outlet 10 are provided in the pressurizing chamber 8. The air inlet 9 of the pressurizing chamber 8 is vertically connected to the air inlet assembly 6, and the air outlet 10 of the pressurizing chamber 8 is connected to the baking chamber 4 of the upper chamber group 2 or the baking chamber 4 of the lower chamber group 3. The wind generated by the DC motor fan is a lateral wind and has centrifugal force. In this embodiment, the pressurizing chamber 8 and the DC motor fan are connected by a vertical connection method to reduce the centrifugal force of the lateral wind and reduce the turbulence between the airflows, so that the wind generated by the DC motor can be accumulated in the pressurizing chamber 8 and then flow along the air outlet 10 to the position of the heating device 5 under continuous pressurization.

[0038] Wherein, the cross-sectional area of the pressurizing air duct 7 where the air inlet 9 is located is larger than the cross-sectional area of the air outlet 10; at the same time, the cross-sectional area of the air outlet 10 is gradually reduced from inside to outside. The air inlet 9 and the air outlet 10 of the pressurizing chamber 8 are set by using Bernoulli's principle to increase the flow velocity of the air flow at the air outlet 10 and provide a strong air flow for food baking. In this embodiment, the disadvantage of insufficient wind force caused by setting the air inlet assembly 6 outside the baking chamber 4 is compensated by setting the pressurizing chamber 8.

[0039] Wherein, the pressurizing air duct 7 includes an air duct body 11 and an air duct cover 12 covering the air duct body 11. At least one air guiding plate 13 is provided at the bottom of the air duct cover 12. The air guiding plate 13 is located at the air outlet 10, and the direction of the air guiding plate 13 is the same as the air outlet direction of the air outlet 10. The air guiding plates 13 are distributed at equal intervals 18. Specifically, this embodiment is provided with five mutually parallel air guiding plates 13.

[0040] In this embodiment, the setting of the air guiding plate 13 is to prevent the air flow from concentrating in the center of the baking chamber 4 and then turning into an air flow that is appropriately dispersed around the baking chamber 4, so that the baking is more uniform and the food baking effect is better.

[0041] In the above embodiment, machine covers are provided on the tops of the upper chamber group 2 and the lower chamber group 3. The machine cover includes a movement cover 14 and a movement inner cover 15. The movement cover 14 is located above the movement inner cover 15, and both the movement cover 14 and the movement inner cover 15 are fixedly connected to the air duct cover 12.

[0042] As Figure 4 As shown in Figures 6 and 7, the movement inner cover 15 is recessed downward to form a wind blocking strip, and the wind blocking strip is arranged horizontally facing the air outlet 10. The wind blocking strip includes a first wind blocking strip 16 and a second wind blocking strip 17. The first wind blocking strip 16 is arranged close to the air outlet 10, the second wind blocking strip 17 is arranged far from the air outlet 10, and the first wind blocking strip 16 is located between the second wind blocking strip 17 and the air outlet 10. The height of the first wind blocking strip 16 recessed relative to the movement inner cover 15 is less than the height of the second wind blocking strip recessed relative to the movement inner cover 15.

[0043] The arrangement of the first wind shield strip 16 and the second wind shield strip 17 in the above structure allows the airflow to be turned downward along the first wind shield strip 16 and the second wind shield strip 17 after exiting the air outlet 10, so that the food is baked more evenly. Specifically, part of the airflow exiting the air outlet 10 encounters the first wind shield strip 16 and then turns into a downward airflow, and part of the airflow encounters the second wind shield strip 17 and then turns into a downward airflow, so that the food in the baking chamber 4 is heated more evenly.

[0044] Specifically, a ventilation gap 18 is reserved between the two sides of the first wind shield 16 and the inner cover 15 of the machine core; a ventilation gap 18 is reserved between the two sides of the second wind shield 17 and the inner cover 15 of the machine core. This arrangement prevents the airflow from the air outlet 10 from being completely blocked by the first wind shield 16 and the second wind shield 17 and flowing downward, and a part of the airflow will flow through the gap 18 to the lower side of the baking chamber 4 away from the air outlet 10, so that the food can be baked in all directions.

[0045] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
