Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a side-ventilation oven. Background Technology

[0002] As people's living standards improve, ovens, as kitchen appliances for baking food, are widely loved by consumers because they can quickly heat food to create a crispy crust while maintaining sufficient nutrients.

[0003] Currently, ovens on the market generally use a fan installed at the back of the inner cavity to circulate hot air, and heating elements are installed around the fan blades. This allows the gas in the inner cavity to first enter the cavity through the air inlet on the hot air baffle, and then, after being heated, flow into the inner cavity under the centrifugal force of the fan blades, thus forming a hot air circulation in the inner cavity to heat the food inside.

[0004] However, the oven's fan is located at the back, which not only makes it difficult for the hot air inlet and outlet to cover the entire baking area, resulting in uneven hot air circulation and uneven heating of food on the baking tray, but also makes the hot air outlet and inlet too close together, easily causing backflow and reducing heat exchange efficiency. Furthermore, hot air blowing from the back towards the front of the oven door can cause the door to overheat, resulting in significant heat loss. Especially if airflow is maintained inside the oven after the door is opened, there is a risk of direct airflow causing burns to the user. Utility Model Content

[0005] Based on this, it is necessary to address the problems of uneven heating of food, easy backflow leading to reduced heat exchange efficiency, large heat loss, or direct airflow causing burns to users in most ovens on the market. This application provides a side-ventilation oven, which can cover the entire food baking area in the inner cavity with hot air, reduce backflow, improve heat exchange efficiency, and reduce heat loss.

[0006] In one embodiment of this application, a side-ventilation oven is provided, comprising: an inner cavity having a front opening; a side-ventilation assembly disposed in the inner cavity, the side-ventilation assembly having an air outlet located on the left and / or right side of the inner cavity and communicating with the internal space of the inner cavity, an air inlet located on the upper and / or lower side of the inner cavity and communicating with the internal space of the inner cavity, and a duct connecting the air outlet and the air inlet; a fan disposed within the duct of the side-ventilation assembly for driving gas to flow from the air inlet to the air outlet in the duct; and a heating element disposed within the duct of the side-ventilation assembly for heating the gas flowing in the duct.

[0007] According to one embodiment of this application, the side-ventilation oven further includes a plurality of baking trays disposed in the internal space of the inner cavity and arranged vertically at intervals; the air outlet in the side-ventilation assembly corresponds to the baking area of ​​the baking tray, and is located between two adjacent layers of the baking trays and above the side of the uppermost baking tray.

[0008] According to one embodiment of this application, the inner liner includes a cavity with the front opening and a support frame fixed to the left and right side walls of the cavity for supporting the baking tray.

[0009] According to one embodiment of this application, the side air duct assembly includes an air outlet duct disposed on the left and right sides of the inner liner and providing the air outlet, an air inlet duct disposed on the left and right sides of the inner liner and communicating with the air outlet duct, and an air inlet baffle disposed on the upper and lower sides of the inner liner and providing the air inlet.

[0010] According to one embodiment of this application, the air inlet baffle is located inside the inner liner and is spaced apart from the upper or lower sidewall of the inner liner to form a flow channel connecting the air inlet and the air inlet duct.

[0011] According to one embodiment of this application, the air inlet is located in the central region of the air inlet baffle.

[0012] According to one embodiment of this application, the heating element is an electric heating tube disposed in a flow channel between the air inlet baffle and the upper or lower side wall of the inner liner.

[0013] According to one embodiment of this application, the fan is a centrifugal fan disposed at the connection between the air outlet duct and the air inlet duct.

[0014] According to one embodiment of this application, the air inlet duct is located outside the air outlet duct.

[0015] According to one embodiment of this application, the air outlet located on the left side of the inner liner corresponds one-to-one with the air outlet located on the right side of the inner liner.

[0016] In summary, because the air outlet in the side air duct assembly of this application is located on the left and / or right side of the inner liner, and the air inlet is located on the upper and / or lower side of the inner liner, the distance between the air outlet and the air inlet in the side air duct assembly is relatively large, reducing backflow and improving heat exchange efficiency. Simultaneously, when hot air flows into the internal space of the inner liner from the air outlet, it will not blow directly towards the front opening of the inner liner, preventing the door from overheating and reducing heat loss. Furthermore, even when the oven door is open and airflow continues, the hot air flowing out through the air outlet will not directly blow onto the front opening of the inner liner, reducing the risk of burns from direct hot air.

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] Considering that the fan of a traditional oven is usually located at the back, the distance between the hot air outlet and inlet is relatively short, which easily leads to backflow and reduces heat exchange efficiency. At the same time, hot air blowing from the back towards the front of the oven door can cause the door to overheat, resulting in significant heat loss. Especially if airflow is maintained inside the oven after the door is opened, there is a risk of direct airflow causing burns to the user. Therefore, this application provides a side-ventilation oven, which can reduce backflow, improve heat exchange efficiency, and reduce heat loss.

[0028] Specifically, see the attached document. Figures 1 to 3 As shown, one embodiment of this application provides a side-ventilation oven 1, which may include an inner cavity 10, a side-ventilation assembly 20, a fan 30, and a heating element 40. The inner cavity 10 has a front opening 100 for placing and removing food to be baked. The side-ventilation assembly 20 is disposed in the inner cavity 10, and the side-ventilation assembly 20 has an air outlet 201 located on the left and / or right side of the inner cavity 10 and communicating with the internal space of the inner cavity 10, an air inlet 202 located on the upper and / or lower side of the inner cavity 10 and communicating with the internal space of the inner cavity 10, and an air duct 203 connecting the air outlet 201 and the air inlet 202. The fan 30 is disposed within the air duct 203 of the side-ventilation assembly 20, for driving gas to flow from the air inlet 202 to the air outlet 201 in the air duct 203. The heating element 40 is disposed within the air duct 203 of the side air duct assembly 20 and is used to heat the gas flowing in the air duct 203. It is understood that the side air duct oven 1 of this application may also include a door assembly (not shown in the figure) covering the inner cavity 10 or other components that assist in realizing the baking function, which will not be described in detail in this application.

[0029] Thus, as Figure 3As shown, when baking food, the gas in the inner liner 10 will first flow into the air duct 203 through the air inlet 202 under the action of the fan 30, and be heated by the heating element 40 to form a hot airflow, and then flow into the internal space of the inner liner 10 through the air outlet 201 to bake the food; thus, a hot air circulation is formed in the internal space of the inner liner 10 until the food is baked.

[0030] It is worth noting that, such as Figure 3 As shown, since the air outlet 201 in the side air duct assembly 20 of this application is located on the left and / or right side of the inner liner 10, and the air inlet 202 is located on the upper and / or lower side of the inner liner 10, the distance between the air outlet 201 and the air inlet 202 in the side air duct assembly 20 is relatively large, reducing backflow and improving heat exchange efficiency. At the same time, when hot air flows into the internal space of the inner liner 10 from the air outlet 201, it will not blow towards the front opening 100 of the inner liner 10, avoiding excessively high door temperature and reducing heat loss. In addition, even if the oven continues to circulate after the door is opened, the hot air flowing out through the air outlet 201 will not blow directly onto the front opening 100 of the inner liner 10, which helps to reduce the risk of users being scalded by direct hot air.

[0031] More specifically, such as Figure 1 and Figure 2 As shown, the side-ventilation oven 1 typically includes multiple baking trays 50 arranged vertically and horizontally within the interior space of the inner cavity 10. In this case, the air outlet 201 in the side-ventilation assembly 20 corresponds to the baking area of ​​the baking tray 50, positioned between adjacent baking trays 50 and above the uppermost baking tray 50. This allows the hot air flowing out through the air outlet 201 to cover the entire food baking area within the inner cavity 10, improving the uniformity of hot air circulation within the inner cavity 10, ensuring even heating of the food on the baking trays, and improving the steaming effect. It is understood that the baking area mentioned in this application refers to the area adjacent to the upper side of the baking tray 50.

[0032] For example, such as Figure 1 and Figure 2 As shown, the side air duct assembly 20 may include an air outlet duct 21 disposed on the left and right sides of the inner liner 10 and providing the air outlet 201, an air inlet duct 22 disposed on the left and right sides of the inner liner 10 and communicating with the air outlet duct 21, and an air inlet baffle 23 disposed on the upper and lower sides of the inner liner 10 and providing the air inlet 202.

[0033] Optionally, such as Figure 1 and Figure 2As shown, the air inlet baffle 23 is located in the internal space of the inner liner 10 and is spaced apart from the upper or lower side wall of the inner liner 10 to form a flow channel connecting the air inlet 202 and the air inlet duct 22, thereby forming the air duct 203 through the flow channel, the air inlet duct 22, and the air outlet duct 21; at the same time, it can also avoid increasing the overall height of the oven 1 in the side air duct.

[0034] Optionally, such as Figure 2 and Figure 3 As shown, the air inlet 202 is located in the middle area of ​​the air inlet baffle 23, so as to maximize the distance between the air inlet 202 and the air outlet 201, ensuring that the hot air flowing out of the air outlet 201 first flows through the food for heating, and then flows into the air duct 203 from the air inlet 202, thereby minimizing the backflow of hot air.

[0035] Optionally, such as Figure 1 and Figure 2 As shown, the fan 30 is implemented as a centrifugal fan 300 located at the connection between the air outlet duct 21 and the air inlet duct 22, which is beneficial to improving the air extraction performance of the fan 30.

[0036] Optionally, such as Figure 1 and Figure 2 As shown, the air inlet duct 22 is located outside the air outlet duct 21 so that the air inlet duct 22 can better extend to the upper and lower sides of the inner liner 10 and avoid structural interference with the air outlet duct 21; at the same time, it also helps to reduce the difficulty of arranging the centrifugal fan 300. As long as the centrifugal fan 300 is placed normally, it can be ensured that the air inlet duct 22 and the air outlet duct 21 correspond to the negative pressure air inlet end and the positive pressure air outlet end of the centrifugal fan 300, respectively.

[0037] In addition, such as Figure 2 and Figure 3 As shown, the air outlet 201 on the left side of the inner pot 10 corresponds one-to-one with the air outlet 201 on the right side of the inner pot 10, so that hot air can be blown from both sides of the inner pot 10 to the central area of ​​the inner pot 10 to heat the food, and then flow up and down from the central area of ​​the inner pot 10 to flow out from the air inlets 202 located on the upper and lower sides of the inner pot 10, which helps to heat the food more evenly and improve the baking effect of the food.

[0038] According to the above embodiments of this application, such as Figure 1 and Figure 2As shown, the heating element 40 can be implemented as an electric heating tube 400 disposed in the flow channel between the air inlet baffle 23 and the upper or lower side wall of the inner liner 10, so that the gas flowing in through the air inlet 202 is first heated into hot air by the electric heating tube 400, and then transported to the fan 30 through the air inlet pipe 22, and then transported to the air outlet 201 through the air outlet pipe 21 to be blown out at high speed from the left and right sides of the inner liner 10, which is beneficial to improving the baking effect of food.

[0039] In addition, such as Figure 1 and Figure 2 As shown, the inner liner 10 of this application may include a cavity 11 with the front opening 100 and a support frame 12 fixed to the left and right side walls of the cavity 11 for supporting the baking pan 50, so as to quickly pick up and put down the baking pan 50. It is understood that the bottom of the baking pan 50 is provided with ventilation holes so that hot air can circulate on the upper and lower sides of the baking pan 50, which is beneficial for better baking of food.

[0040] In summary, as Figures 1 to 3 As shown, the air outlet 201 of the side air duct assembly 20 is located between two adjacent support frames 12, and between the uppermost support frame 12 and the corresponding air inlet baffle 23, so as to ensure that the hot air flowing out of the air outlet 201 can directly blow on the food supported by the corresponding baking tray 50.

[0041] It is worth noting that the side-ventilation oven 1 of this application can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the side-ventilation oven 1 to perform corresponding operations, thereby realizing intelligent control of the side-ventilation oven 1 and improving the user experience.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
