When the heat dissipation performance of the product is limited, excessive temperature rise will cause the controller of the product to malfunction, and thus the whole machine cannot work normally. SUMMARY

[0003] Therefore, the utility model provides a flow guide structure, a base and a household appliance to solve the problem that the controller of the household appliance is prone to malfunction due to temperature rise.

[0005] Beneficial effects: when the flow guide structure is arranged between the base assembly and the fixing frame, cooling air enters the inside of the base assembly from the air inlet, and then enters the inside of the fixing frame to cool the electrical components in the inside of the fixing frame. The cooling air becomes hot air after carrying the heat emitted by the electrical components, and the hot air is discharged from the first air outlet.

The cooling air flow becomes hot air flow after carrying the heat emitted by the heating assembly, and the hot air flow is discharged from the first air outlet. Therefore, the heat of the electrical components can be carried away in time to prevent the deformation or even fire caused by the high temperature in the base. In addition, by setting the flow guide structure, the flow guide structure defines the air outlet channel of the air flow from the second air outlet to the first air outlet, which can avoid the hot air flow flowing in other directions except the first air outlet after flowing out from the second air outlet, thereby avoiding the heat transfer to the other electrical components arranged between the fixed frame and the base assembly, causing the damage of the other electrical components, so as to ensure the normal work of the whole machine.

DETAILED DESCRIPTION

[0057] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0058] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0059] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between the two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0060] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0061] For electric kettles, electric rice cookers and other household appliances for heating food, a large part of the added value is reflected in the reduction of working time, that is, fast boiling or fast cooking. Fast boiling and fast cooking mean that the power of the whole machine is improved, so stronger heat dissipation performance is required. When the heat dissipation performance of the product is limited, excessive temperature rise will cause the controller of the product to malfunction, thereby causing the whole machine to malfunction.

[0062] In combination Figure 1 , Figure 1 is a schematic view of a related art base, which comprises a base assembly 1, a fixed frame 6, a microcrystalline plate 10, a heating assembly 2, a support ring 9, a fan 3 and a controller 4. The base assembly 1 has an air inlet 1021 and a first air outlet 1011. The air inlet 1021 is located on the bottom wall, and the first air outlet 1011 is located on the side wall. The fixed frame 6 is arranged inside the base assembly 1, and there is a mounting space 8 between the bottom of the fixed frame 6 and the bottom wall of the base assembly 1. The fan 3 is located in the mounting space 8. The side of the fixed frame 6 has a gap with the side wall of the base assembly 1, and the controller 4 is located in the gap. The fixed frame 6 is provided with a stepped portion, and the microcrystalline plate 10 is arranged on the stepped portion. The support ring 9 is fixedly connected with the base assembly 1 and abuts against the microcrystalline plate 10. When the base works, the fan 3 works, and the cooling air flow enters the inside of the base assembly 1 from the air inlet 1021, then passes through the fan 3 to enter the inside of the fixed frame 6, and flows through the heating assembly 2. After the cooling air flow carries the heat emitted by the heating assembly 2, it becomes a hot air flow. The hot air flow passes through the opening of the side of the fixed frame 6 and is discharged from the first air outlet 1011. Therefore, the heat of the heating assembly 2 can be carried away in time, and the temperature inside the base is prevented from being too high to cause deformation or even fire.

[0063] However, the above related art, as shown in Figure 2 , after the hot air flow passes through the opening of the side of the fixed frame 6, part of it will flow to the space where the controller 4 is located through the gap between the side of the fixed frame 6 and the side wall of the base assembly 1, thereby causing the temperature of the controller 4 to be too high and affecting its stability. Another part of the hot air flow will flow downward and accumulate below the fixed frame 6, and will transfer the heat from the fan 3 to the newly inhaled cold air, affecting the heat dissipation effect of the whole machine, and at the same time, will flow to the lower part of the controller 4, affecting the stability of the controller 4.

[0064] The embodiments of the utility model are described below in combination with Figures 3 to 11 .

The cooling airflow becomes hot airflow after carrying the heat emitted by the electrical components, and the hot airflow is discharged from the first air outlet 1011. Therefore, the heat of the electrical components can be timely carried away, and deformation or even fire caused by excessive temperature in the interior of the base can be prevented. In addition, the flow guide structure 5 defines the air outlet channel 7 that the air outlet flows from the second air outlet 602 to the first air outlet 1011.

[0099] In one embodiment, the mounting portion 506 is further provided with a second side blocking edge 513, which abuts against the side of the wire outlet 605 close to the second air outlet 602.

[0100] In this embodiment, by arranging the second side blocking edge 513, the second side blocking edge 513 and the first side blocking edge 512 and the bottom blocking edge 501 cooperate to block the hot air flow from flowing out of the wire outlet 605, so as to avoid the hot air flow from flowing to other electrical components arranged between the fixing frame 6 and the base assembly 1, thereby preventing the other electrical components from being damaged and ensuring normal operation of the whole machine.

[0101] In one embodiment, the area between the second side blocking edge 513 and the first side blocking edge 512 is adapted to accommodate the wire.

[0102] In this embodiment, the area between the second side blocking edge 513 and the first side blocking edge 512 can accommodate the wire, and the wire can pass through the wire slot 508 provided by the bottom blocking edge 501 to exit, thereby avoiding extrusion of the wire.

[0103] Specifically, in one embodiment, the power supply wire connected to the heating assembly 2 and the connecting wire of the temperature sensing bag pass through the wire slot 508 after exiting the wire outlet 605 and are connected to the controller 4.

[0105] In this embodiment, by arranging the stepped portion 606 on the fixing frame and the arc-shaped raised edge 514 on the top blocking edge 502, the arc-shaped raised edge 514 abuts against the stepped portion 606, thereby facilitating positioning of the top blocking edge 502.

[0106] In a second aspect, a base is provided, which includes the base assembly 1, the fixing frame 6, and the flow guide structure 5 provided in the above embodiments. The flow guide structure 5 is arranged between the base assembly 1 and the fixing frame 6, and defines an air outlet channel 7 through which the air flows from the second air outlet 602 to the first air outlet 1011.

[0107] In this embodiment, when the base is working, cooling air flows into the inside of the base assembly 1 from the air inlet 1021, then into the inside of the fixing frame 6 to cool the electrical components in the inside of the fixing frame 6. The cooling air carrying the heat emitted by the electrical components becomes hot air flow, which is discharged from the first air outlet 1011. Thus, the heat of the electrical components can be carried away in time to prevent the base from deforming or even catching fire due to high temperature. In addition, by arranging the flow guide structure 5, the flow guide structure 5 defines the air outlet channel 7 through which the air flows from the second air outlet 602 to the first air outlet 1011. The hot air flow discharged from the second air outlet 602 can be prevented from flowing in other directions except the first air outlet 1011, thereby preventing the heat from being transferred to other electrical components arranged between the fixing frame 6 and the base assembly 1, so as to prevent the other electrical components from being damaged.

[0108] In one embodiment, a heat dissipation air duct is formed between the air inlet 1021 and the first air outlet 1011. The base further comprises a heating assembly 2, a fan 3 and a controller 4.

The controller 4 is arranged in the space between the base assembly 1 and the fixing frame 6 and located outside the air outlet channel.

[0109] In this embodiment, when the base is working, the fan 3 works to make the cooling air flow into the heat dissipation air duct from the air inlet 1021. Since at least part of the heating assembly 2 is arranged in the heat dissipation air duct, the cooling air will cool the heating assembly 2. The cooling air carrying the heat emitted by the heating assembly 2 becomes hot air flow, which is discharged from the second air outlet 602 and then discharged from the first air outlet 1011 under the limitation of the air outlet channel 7. Thus, the heat of the heating assembly 2 can be carried away in time to prevent the base from deforming or even catching fire due to high temperature. Since the heat of the heating assembly 2 can be carried away in time, the power of the heating assembly 2 can be increased to realize fast water boiling or food heating. In addition, the controller 4 is arranged in the space between the base assembly 1 and the fixing frame 6 and located outside the air outlet channel 7. The flow guide structure 5 can block the air outlet channel 7 and the controller 4. The flow guide structure 5 blocks the hot air flow from flowing to the controller 4, which can prevent the controller 4 from malfunctioning due to temperature rise, thereby ensuring the normal working of the whole machine.

[0111] In this embodiment, since the bottom of the fixing frame 6 and the base assembly 1 have the mounting space 8, the fan 3 is arranged in the mounting space 8, and the flow guide structure 5 blocks the air outlet channel 7 and the mounting space 8. The hot air flow can be prevented from mixing with the newly inhaled cooling air of the fan 3 again, thereby avoiding affecting the heat dissipation effect of the whole machine.

[0112] Specifically in one embodiment, the base assembly 1 comprises a base 101 and a bottom cover 102, the bottom cover 102 is connected to the bottom of the base 101, and the air inlet 1021 is arranged on the bottom cover 102.

[0113] In this embodiment, the base assembly 1 comprises a base 101 and a bottom cover 102, and when assembled, the fan 3 can be assembled at the bottom of the fixing frame 6 after the base 101 and the fixing frame 6 are assembled, and then the bottom cover 102 is connected to the bottom of the base 101, facilitating the assembly of the entire base.

[0114] In one embodiment, the base further comprises a support ring 9 and a microcrystalline plate 10, the microcrystalline plate 10 is arranged above the heating assembly 2, and the support ring 9 is fixedly connected with the fixing frame 6 and is sealingly connected with the edge of the microcrystalline plate 10 through a sealing ring 11.

[0115] In this embodiment, the microcrystalline plate 10 can place a kettle or other cooking utensils that need to be heated, and the support ring 9 is fixedly connected with the fixing frame 6 and sealingly connected with the edge of the microcrystalline plate 10, which can prevent water from entering the inside of the base through the edge of the microcrystalline plate 10.

[0116] In one embodiment, a sealing ring 11 is arranged between the lower end of the support ring 9 and the microcrystalline plate 10, and the sealing ring 11 can block food or water from flowing into the inside of the base.

[0117] In one embodiment, as shown in Figure 5 , the cross section of the sealing ring 11 is L-shaped, comprising a ring body part 1101 and a blocking part 1102 connected to the outer periphery of the ring body part 1101, the blocking part 1102 surrounds the outside of the lower end of the support ring 9, and the support ring 9 can pre-tighten the sealing ring 11.

[0118] In one embodiment, at least one annular sealing rib 1103 is protrudingly arranged at the lower end of the sealing ring 11, and the sealing rib 1103 abuts against the microcrystalline plate 10.

[0119] Specifically in one embodiment, the heating assembly 2 comprises a heating disc.

[0120] Specifically as shown in Figure 3 and Figure 4 , the air inlet 1021 is arranged on the bottom surface of the base assembly 1. The cooling air flow enters from the bottom air inlet 1021, passes through the air fan 3, and then enters the inside of the fixing frame 6 through the air passing hole 601 at the bottom of the fixing frame 6, becomes a hot air flow after flowing through the heating assembly 2, and then passes through the second air outlet 602 and is blown out from the first air outlet 1011.

[0121] According to the embodiments of the present application, in a third aspect, a household appliance is provided, comprising the base provided in the above embodiments.

[0122] When the base is working, the cooling air current enters the inside of the base assembly 1 from the air inlet 1021, then enters the inside of the fixed frame 6 to cool the electrical components in the fixed frame 6, and the cooling air current becomes hot air current after carrying the heat emitted by the electrical components, and the hot air current is discharged from the first air outlet 1011, so that the heat of the electrical components can be carried away in time to prevent the base from deforming or even catching fire due to high temperature. In addition, by arranging the flow guide structure 5, the flow guide structure 5 defines the air outlet channel 7 through which the air is discharged from the second air outlet 602 to the first air outlet 1011, so that the hot air current can be prevented from flowing in other directions except the first air outlet 1011 after being discharged from the second air outlet 602, and then the heat can be prevented from being transferred to other electrical components arranged between the fixed frame 6 and the base assembly 1, so as to prevent the other electrical components from being damaged.
