The utility model provides an electricity rice cooker heat radiation structure. This electricity rice cooker heat radiation structure and electricity rice cooker casing cooperation installation are used for the heat dissipation when electricity rice cooker heats, are applied to during powerful electricity rice cooker structure, and its radiating effect is better, and the structure is comparatively simple, when avoiding electricity rice cooker heating plate heating power too big, the inside high temperature of electricity rice cooker leads to the phenomenon that inside electrical part burns out.
In an embodiment of the present invention, as shown in fig. 1 to 4, a heat dissipation structure of an electric cooker comprises an electric cooker chassis 1, wherein the electric cooker chassis 1 is a cavity with an upward opening formed by a bottom plate 11 and a side wall 12, and a heat dissipation assembly 2 is installed on the bottom plate 11;
the heat dissipation component 2 comprises a heat dissipation fan 21 communicated with the outside of the cavity, and a plurality of air outlets 13 are formed in the bottom plate 11 and/or the side wall 12;
the heat dissipation assembly 2 further includes a circuit board 22, a heat sink 23 is disposed on the circuit board 22, and a flow guiding member 24 for transmitting cool air to the heat sink 23 is disposed on at least one of the heat dissipation fans 21.
Specifically, electricity rice cooker chassis 1 includes bottom plate 11 and lateral wall 12 to bottom plate 11 and lateral wall 12 form a cavity structure jointly, can be used to the installation of the all the other parts of electricity rice cooker, still is provided with the radiator unit 2 that promotes the inside radiating effect of electricity rice cooker on the bottom plate 11, and radiator unit 2 sets up at the middle part of bottom plate 11 in this scheme, and in the use scene of difference, radiator unit 2 can install the different positions at bottom plate 11. Radiator unit 2 specifically includes radiator fan 21, makes cold air to the inside conveying of cavity through radiator fan 21, and after electric rice cooker chassis 1 and the cooperation installation of dish that generates heat, cold air can be cooled down the dish department that generates heat, and the hot-air that later forms discharges to the external world through air outlet 13, and is equipped with two sets of opposite direction of rotation's radiator fan 21 in electric rice cooker chassis 1, and radiator fan 21 sets up side by side on bottom plate 11, and the design is more integrated. Because the heat radiation fan 21 can be further provided with the diversion piece 24, the cold air is transmitted to the radiator 23 through the diversion piece 24, because the radiator 23 is arranged on the circuit board 22, in the use process of the electric cooker, the temperature is higher because a plurality of electric devices are arranged above the circuit board 22, the radiator 23 can realize the heat radiation of the circuit board 22, meanwhile, the cold air transmitted to the radiator 23 by the diversion piece 24 further cools the radiator 23, the temperature in the cavity can be further reduced, the double heat radiation is realized, the heat radiation effect is better, and the air outlet 13 can be circular or an opposite-shaped hole and the like.
Further, the heat dissipation assembly 2 further includes an installation plate 25 installed on the bottom plate 11, the installation plate 25 is provided with a plurality of air inlets 251, and the positions of the air inlets 251 correspond to the positions of the heat dissipation fans 21. So, cold air can directly get into to the cavity in through the radiator fan 21 that switches on, also can transmit to radiator fan 21 reentrant cavity through air intake 251 in, so set up, to radiator fan 21's protection effect preferred, prevent that it from receiving external force impact and damaging in transportation or installation.
Further, the radiator 23 is located below the air guide 24. Therefore, the path for transporting the cold air in the diversion piece 24 is short, the installation positions of the heat radiation fan 21 and the radiator 23 are close, and the heat radiation effect of the diversion piece 24 on the radiator 23 is better.
Further, the heat dissipation assembly 2 includes a partition 26 surrounding the outside of the heat dissipation fan 21, and the partition 26 and the air guide member 24 are attached to each other to form an accommodation space, and the heat dissipation fan 21 is installed in the accommodation space.
Specifically, the setting of partition 26 can effectually prevent that the hot air in the cavity from being inhaled by radiator fan 21, influence radiator fan 21 to the suction effect of external cold air to partition 26 can also cooperate with water conservancy diversion piece 24, forms an inside accommodation space (not shown in the figure) after laminating with water conservancy diversion piece 24 when the installation, and radiator fan 21 direct mount is in the accommodation space, and water conservancy diversion piece 24 is better to the transmission effect of cold air.
Further, the air outlet 13 is located on a side away from the heat dissipation fan 21. The air outlet 13 in this scheme is great with radiator fan 21's setting interval, and the hot and cold air convection current of being convenient for has further promoted the radiating effect on electric rice cooker chassis 1.
Further, the inner side of the deflector 24 is provided with a plurality of corrugated grooves for promoting air convection. It can be understood that the inner side of the air guiding element 24 is used for transmitting cold air to dissipate heat of the heat sink 23, and after the corrugated grooves (not shown in the figure) are formed, the cold air forms a vortex effect in the air guiding element 24, which promotes air convection and increases heat dissipation effect.
Further, a plurality of reinforcing ribs 241 are arranged on the flow guide member 24. So, water conservancy diversion piece 24 in this scheme is less at thickness usually when production, consequently sets up strengthening rib 241 cooperation water conservancy diversion piece 24 very easily when the installation because deformation appears in external force, and strengthening rib 241 specifically can set up in the top of water conservancy diversion piece 24 or below wait position, does not influence water conservancy diversion piece 24 to cold air transmission effect can.
Further, the outlet 13 located in the side wall 12 is a through hole formed by the side wall 12 being recessed inward.
It can be understood that the side wall 12 still belongs to the part which can be observed directly after being assembled with the rice cooker shell, because the air outlet 13 on the side is formed by the inward recess of the side wall 12, the internal structure of the rice cooker is difficult to be seen directly when being observed from the front, the opening position of the air outlet 13 can be seen only from the side, and the whole structure is more beautiful.
Further, the heat sink 23 is made of a known aluminum alloy. Therefore, the radiator 23 is made of aluminum alloy, the heat conductivity is good, the best heat dissipation effect is guaranteed, the cost of the aluminum alloy is relatively low, the aluminum alloy can be processed into any required shape, and the cost performance of the manufactured radiator 23 is high; meanwhile, the aluminum alloy has better high temperature resistance, oxidation resistance and corrosion resistance, a compact aluminum oxide film can be generated when oxygen in the air is met, and the adaptability of the radiator 23 to high-temperature and humid environments is improved.
In addition, this scheme still provides an electric rice cooker, uses the electric rice cooker heat radiation structure as above-mentioned arbitrary. The heat dissipation principle and structure of the heat dissipation structure of the electric cooker are consistent with those described above, and are not repeated one by one.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
