Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a ventilation and heat dissipation structure for an embedded stove. Background Technology

[0002] In the design of built-in appliances, especially those that need to be placed in cabinets, heat dissipation has always been a crucial aspect that cannot be ignored during the design process. Traditional heat dissipation systems typically rely on internal air ducts and fans to dissipate heat from the appliance's internal components. However, appliances placed in cabinets often face design limitations in terms of external heat dissipation channels, resulting in ineffective heat dissipation.

[0003] Because cabinet structures are typically custom-made to fit the dimensions of appliances and cannot be easily modified, the external ventilation design usually involves only one shared air intake and exhaust duct. This design, limited by the internal space of the cabinet, results in insufficient heat dissipation circulation in the external airflow. Specifically, hot air exhausted from the exhaust vent often cannot effectively escape the cabinet and may instead re-enter the fan's intake. Consequently, the fan draws in heated air instead of cool air, thus affecting the appliance's internal heat dissipation.

[0004] Currently, many solutions for optimizing heat dissipation from internal heat sources in electrical appliances focus primarily on improving the appliance's internal structure. For example, increasing motor speed and fan speed / volume can improve heat dissipation efficiency; adjusting the position and shape of the radiator can enhance heat dissipation; additionally, some designs further optimize heat dissipation by adjusting the layout of internal air ducts to increase airflow to the heat source. However, while these internal optimization solutions can improve heat dissipation performance to some extent, innovation and improvement in external air duct design are relatively limited. Inadequacies in external air duct design, especially the problem of poor heat circulation between the appliance and the cabinet, remain a key factor affecting the appliance's heat dissipation efficiency.

[0005] Therefore, how to further optimize the design of the external heat dissipation channel and solve the problem of external hot air entering the fan intake port while keeping the cabinet structure unchanged has become an important issue that urgently needs to be addressed in the current heat dissipation technology of embedded appliances. Utility Model Content

[0006] Addressing the problem of low heat dissipation efficiency caused by the re-drawing of hot air after heat dissipation by the fan in existing technologies, this invention provides a ventilation and heat dissipation structure for an embedded stove. By setting a guide plate in the external air duct, the exhaust hot air does not flow back to the air inlet, but instead flows to both sides through the external air duct, thereby effectively preventing the fan from drawing in hot air and improving the heat dissipation efficiency inside the stove.

[0007] This utility model provides a ventilation and heat dissipation structure for an embedded stove, including:

[0008] The cabinet has a mounting cavity at the top and a ventilation channel inside that connects to the outside of the cabinet.

[0009] A cooktop is embedded in an installation cavity. The cooktop includes a housing and a cooling fan located inside the housing. The housing has an air inlet and an air outlet, and an internal air duct is formed inside the housing.

[0010] An external air duct is formed between the outer shell and the mounting cavity, and the external air duct is connected to the internal air duct and the ventilation channel.

[0011] A deflector plate is disposed in the external air duct, located between the air inlet and the air outlet. The deflector plate divides the external air duct, causing the airflow discharged from the exhaust outlet to flow to both sides through the deflector plate and be discharged through the ventilation channel, thereby preventing the airflow from flowing back to the air inlet.

[0012] In some embodiments, the air inlet is located on the bottom surface of the housing, and the bottom surface of the housing and the bottom surface of the mounting cavity form the external air duct.

[0013] In some embodiments, the ventilation duct includes at least a vertical channel located at the rear of the cabinet, the top of which communicates with the external air duct.

[0014] In some embodiments, the ventilation channel further includes a horizontal channel located at the bottom of the cabinet, the horizontal channel being connected to the vertical channel.

[0015] In some embodiments, the air inlet is disposed near the vertical channel, and the air outlet is disposed away from the vertical channel; the guide plate is disposed near the air inlet.

[0016] In some embodiments, the guide plate is an arc-shaped plate, with both ends of the guide plate extending to the sides and towards the ventilation channel.

[0017] In some embodiments, the exhaust vent is disposed on the side of the housing, and the exhaust vent includes at least one row of through holes opened along the side of the housing.

[0018] In some embodiments, the guide vane is composed of multiple guide vanes connected sequentially in the height direction, and the multiple guide vanes are connected by an adjustable connection structure to adjust the overall height of the guide vane.

[0019] In some embodiments, the adjustable connection structure is a hook and slot structure, wherein in two adjacent guide vanes, one guide vane is provided with a hook, and the other guide vane is provided with multiple slots of different heights. The hook and slots cooperate to allow the lower guide vane to be suspended on the upper guide vane.

[0020] In some embodiments, the adjustable connection structure is a sliding structure, in which two adjacent guide vanes are connected by sliding up and down through the sliding structure.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are:

[0022] The ventilation and heat dissipation structure of the aforementioned built-in cooktop features a deflector plate that separates the external air duct, preventing exhaust hot air from flowing back to the air inlet. Instead, the exhaust air flows to both sides through the external air duct, effectively preventing the fan from drawing in hot air and maintaining the appliance's internal heat dissipation efficiency. Furthermore, the design connecting the external air duct to the cabinet's ventilation channel allows hot air to be effectively exhausted through the external air duct, solving the problem of insufficient heat dissipation caused by space constraints in built-in cooktops within cabinets.

[0043] Reference Figures 1-11 These are some embodiments of the ventilation and heat dissipation structure of the embedded stove of this utility model.

[0044] The ventilation and heat dissipation structure of the built-in cooktop includes a cabinet 100, a cooktop 200, and a baffle plate 300.

[0045] like Figure 1 , Figure 2 and Figure 5 The top of the cabinet 100 is provided with an installation cavity 110, and a ventilation channel 120 is provided inside the cabinet 100, which is connected to the outside of the cabinet 100.

[0046] The cooktop 200 is embedded in the mounting cavity 110 of the cabinet 100. The cooktop 200 includes a housing 210 and a cooling fan 220 disposed within the housing 210. Figure 5 and Figure 6 As shown, the outer casing 210 is provided with an air inlet 211 and an air outlet 212. An internal air duct A is formed inside the outer casing 210. The cooling fan 220 draws in cold air into the internal air duct A through the ventilation channel 120 of the cabinet 100 and the air inlet 211 (the flow direction is indicated by the hollow arrow) to dissipate heat from the components 230 inside the stove 200.

[0047] An external air duct B is formed between the outer casing 210 and the mounting cavity 110. The external air duct B is connected to the internal air duct A of the stove 200 and the ventilation channel 120 of the cabinet 100, thereby realizing the flow and exhaust of external air.

[0048] To solve the problem of hot air recirculation to air inlet 211, such as Figure 3 , Figure 8 and Figure 9As shown, a baffle 300 is installed in the external air duct B. The baffle 300 is located between the air inlet 211 and the air outlet 212. The baffle 300 divides the external air duct, causing the airflow discharged from the air outlet 212 (flow direction indicated by the solid arrow) to flow to both sides through the baffle 300 and be discharged through the ventilation channel 120 of the cabinet 100. This prevents hot air from flowing back to the air inlet 211 and ensures that the air inlet 211 draws in cold air (flow direction indicated by the hollow arrow).

[0049] In the aforementioned ventilation and heat dissipation structure, the deflector plate 300 prevents the exhausted hot air from flowing back to the air inlet 211. Instead, it directs the air to both sides through the external air duct, effectively preventing the fan from drawing in hot air and maintaining the heat dissipation efficiency inside the appliance. Furthermore, the design of connecting the external air duct to the ventilation channel 120 of the cabinet 100 allows hot air to be effectively exhausted through the external air duct, solving the problem of insufficient heat dissipation for built-in cooktops in the cabinet 100 due to space limitations.

[0050] In some embodiments of this application, such as Figure 2 As shown, the air inlet 211 is located on the bottom surface of the housing 210, and an external air duct is formed between the bottom surface of the housing 210 and the bottom surface of the mounting cavity 110. A cooling fan 220 is provided on the inner side of the air inlet 211, and the air inlet 211 is preferably a circular grille structure.

[0051] The air inlet 211 is located on the bottom surface of the outer casing 210, which facilitates the placement of the cooling fan 220 inside the cooktop 200. At the same time, it makes the shape of the external air duct more compact, adapting to the limited space of the cabinet 100, which helps to optimize the airflow path and improve heat dissipation efficiency.

[0052] In some embodiments of this application, such as Figure 5 As shown, the ventilation duct 120 includes at least a vertical duct 121 located behind the cabinet 100, and the top of the vertical duct 121 is connected to the external air duct.

[0053] The vertical channel 121 helps guide the exhaust hot air to flow along the rear side of the cabinet 100, thereby preventing hot air from flowing back to the air inlet 211. The design of the vertical channel 121 can effectively utilize the rear space of the cabinet 100 and further optimize the airflow path of the external air duct.

[0054] In some embodiments of this application, such as Figure 5 As shown, in addition to the vertical channel 121, the ventilation channel 120 also includes a horizontal channel 122 located at the bottom of the cabinet 100. This horizontal channel 122 is connected to the vertical channel 121.

[0055] By setting up the horizontal channel 122, the intake and exhaust airflows can enter and exit from the front of the cabinet 100, improving the airflow efficiency of the ventilation channel 120. In some other embodiments, the intake and exhaust airflows can be set to enter and exit from the bottom or side of the cabinet 100.

[0056] In some embodiments of this application, such as Figure 9 As shown, the air inlet 211 is positioned close to the vertical channel 121, while the exhaust outlet 212 is positioned away from the vertical channel 121, and the baffle 300 is positioned close to the air inlet 211. The placement of the air inlet 211 close to the vertical channel 121 helps guide cold air directly into the interior of the housing 210, preventing the mixing of hot and cold air. The placement of the baffle 300 close to the air inlet 211 ensures that the airflow at the exhaust outlet 212 can effectively flow to both sides and be smoothly discharged through the external air duct.

[0057] Through the above-mentioned reasonable layout, the airflow direction of the air inlet 211 and the air outlet 212 is effectively controlled, thereby avoiding mutual interference between cold air and hot air and ensuring that the cooling fan 220 can always draw in cold air.

[0058] In some embodiments of this application, such as Figure 9 As shown, the deflector plate 300 is an arc-shaped plate with both ends extending to the sides and towards the ventilation channel 120.

[0059] The arc-shaped deflector 300 effectively changes the airflow direction, allowing hot air to flow more evenly to both sides during exhaust, thereby improving hot air exhaust efficiency. Simultaneously, it prevents hot air from concentrating on one side during exhaust, thus enhancing overall heat dissipation efficiency and airflow performance.

[0060] In some embodiments of this application, the exhaust vent 212 is disposed on the side of the housing 210, and the exhaust vent 212 includes at least one row of through holes opened along the side of the housing 210.

[0061] The side exhaust vent 212 design avoids direct contact between the exhaust port and the air inlet 211, reducing the risk of airflow backflow. The design of multiple exhaust vents ensures that air can flow evenly, improving heat dissipation efficiency and preventing a decrease in heat dissipation performance due to uneven airflow.

[0062] In some embodiments of this application, such as Figure 10 As shown, the guide vane 300 is composed of multiple guide vanes 310 connected sequentially in the height direction. The multiple guide vanes 310 are connected by an adjustable connection structure to adjust the overall height of the guide vane 300.

[0063] The adjustable connection structure allows the height of the baffle 300 to be flexibly adjusted, enabling the baffle 300 to be adjusted according to actual needs, thereby adapting to the space requirements of different appliances and cabinets 100.

[0064] In some embodiments of this application, such as Figure 10 and Figure 11 As shown, the adjustable connection structure is a hook and slot structure. In the hook and slot structure, two adjacent guide vanes 310 are provided with a hook 311 on one side and multiple slots 312 at different heights on the other side. The hook 311 cooperates with the slots 312, so that the lower guide vane 310 is suspended on the upper guide vane 310. By hanging on the slots 312 at different heights, the overall height of the guide vane 300 can be adjusted.

[0065] See Figure 11 The guide plate 300 consists of two guide plates 310. The upper guide plate 310 is fixedly connected to the bottom of the outer shell 210 and is provided with a hook 311. The lower guide plate 310 is provided with a slot 312. Multiple slots 312 of different heights are connected at one end, which makes it easy for the hook 311 to slide and adjust in the slots 312 of different heights.

[0066] The height of the air deflector 300 can be easily adjusted via the connection of hook 311 and slot 312, ensuring it adapts to different heat dissipation requirements. This design is simple and reliable, effectively improving the flexibility and ease of adjustment of the air deflector 300.

[0067] In some other embodiments of this application, the adjustable connection structure is a sliding structure (not shown). Two adjacent guide vanes 310 are slidably connected up and down through the sliding structure, thereby realizing the height adjustment of the guide plate 300.

[0068] The sliding structure makes the adjustment between the guide vanes 310 more flexible and smooth, while improving the adjustment efficiency and ensuring that the guide vane 300 can be precisely adjusted to the appropriate height.

[0069] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
