Description

Technical Field

[0001] This utility model relates to the field of rice cooker technology, and in particular to an anti-overflow structure for a rice cooker. Background Technology

[0002] When a rice cooker is cooking rice, the rice water produces hot bubbles. These bubbles accumulate and rise slowly, eventually overflowing through the vent, causing the rice cooker to overflow. This affects the hygiene and cleanliness of the rice cooker, and the overflowing hot bubbles can easily damage the electrical components. Traditional rice cookers use a steam valve to prevent the hot bubbles from overflowing, but this valve is not very effective, especially when there are many hot bubbles. Some rice cookers use a bubble-breaking mechanism to prevent overflow, but hot steam from the vent can flow back into this mechanism.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-overflow structure for a rice cooker that is simple in structure, has a good anti-overflow effect, can prevent hot steam backflow, provides a good user experience, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] An anti-overflow structure for a rice cooker designed for this purpose includes an exhaust port connected to the inner pot, characterized in that: it also includes a fan disposed on one side of the exhaust port, the air outlet of the fan is connected to the exhaust port, and cold air blown from the air outlet of the fan enters the exhaust port.

[0006] An air guide is installed between the air outlet and the exhaust port of the fan. A one-way valve is installed on the air guide. The one-way valve opens under the blowing action of the air outlet, so that the cold air blown out of the air outlet enters the exhaust port.

[0007] The one-way valve includes two air guide vanes that form a figure-eight shape with each other. The air guide vanes are elastic. The openings of the two air guide vanes face the air outlet of the fan, and the closed openings of the two air guide vanes face the exhaust port. The closed openings of the two air guide vanes are elastically opened under the blowing action of the air outlet, so that the cold air blown out of the air outlet can enter the exhaust port.

[0008] An air inlet is provided on the side of the exhaust port, and a plug-in groove is provided on the air guide. The air inlet and the plug-in groove are plugged into each other to fix the air guide on the exhaust port.

[0009] The one-way valve is located inside the air inlet.

[0010] The air guide is made of silicone material.

[0011] The rice cooker includes a cooker body and a top lid. The top lid is located on top of the cooker body, and the exhaust port is located inside the top lid. An electrical cavity is formed between the cooker body and the top lid. The fan is located inside the electrical cavity, and the air inlet of the fan is connected to the electrical cavity.

[0012] The top cover is equipped with an air inlet, through which the electrical cavity is connected to the outside world.

[0013] The electrical cavity contains a control circuit board, which is electrically connected to the fan.

[0014] The inner liner is covered with an inner cover, which has several through holes through which the inner liner connects to the vent. The top cover has a vent that connects to the outside, and the vent connects to the vent.

[0015] This rice cooker features a fan installed on one side of the exhaust port. The fan's outlet is connected to the exhaust port, and the fan blows cold air into the exhaust port. The cold air breaks up the hot bubbles that accumulate on the exhaust port after boiling, preventing them from rising and thus preventing overflow. This structure can quickly break up a large number of hot bubbles, making it particularly suitable for situations with many hot bubbles. In addition, an air guide is installed between the fan's outlet and the exhaust port, and a one-way valve is installed on the air guide. The one-way valve prevents hot steam from flowing back into the fan from the exhaust port, thus preventing the hot steam from damaging the fan. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-6 The overflow prevention structure of this rice cooker includes an exhaust port 2 connected to the inner pot 1, and a fan 3 located on one side of the exhaust port 2. The air outlet 4 of the fan 3 is connected to the exhaust port 2. The cold air blown from the air outlet 4 of the fan 3 enters the exhaust port 2 to break the hot air bubbles piled up on the exhaust port 2. The fan 3 is a blower.

[0024] A guide 5 is provided between the air outlet 4 and the exhaust port 2 of the fan 3. A one-way valve is provided on the guide 5. The one-way valve opens under the blowing action of the air outlet 4, so that the cold air blown out of the air outlet 4 enters the exhaust port 2. The one-way valve can realize the cold air from one side. The hot steam on the exhaust port 2 cannot enter the fan 3 through the one-way valve.

[0025] The one-way valve includes two guide vanes 6 that form a V-shape with each other. The guide vanes 6 are elastic. The V-shaped openings of the two guide vanes 6 face the air outlet 4 of the fan 3, and the V-shaped closings of the two guide vanes 6 face the exhaust port 2. The V-shaped closings of the two guide vanes 6 are elastically opened under the blowing action of the air outlet 4, so that the cold air blown out of the air outlet 4 can enter the exhaust port 2. The hot steam on the exhaust port 2 cannot pass through the V-shaped closings of the two guide vanes 6, and therefore cannot enter the fan 3. When the fan 3 stops blowing, the V-shaped closings of the two guide vanes 6 are elastically closed (i.e., reset).

[0026] An air inlet 7 is provided on the side of the exhaust port 2, and an insertion groove 8 is provided on the air guide 5. The air inlet 7 and the insertion groove 8 are inserted into each other so that the air guide 5 is fixed on the exhaust port 2. One end of the air guide 6 is connected to the bottom wall of the insertion groove 8.

[0027] The one-way valve is located inside the air inlet 7, that is, the air guide vane 6 is located inside the air inlet 7.

[0028] The air guide component 5 is made of silicone material.

[0029] The rice cooker includes a cooker body 9 and a top cover 10. The inner pot 1 is located inside the cooker body 9, and the top cover 10 is placed on top of the cooker body 9. The exhaust port 2 is located inside the top cover 10. An electrical cavity 11 is formed between the cooker body 9 and the top cover 10. The fan 3 is located inside the electrical cavity 11, and the air inlet 12 of the fan 3 is connected to the electrical cavity 11.

[0030] The top cover 10 is provided with an air inlet (not shown in the figure). The electrical cavity 11 is connected to the outside through the air inlet. When the fan 3 is working, the outside cold air enters the electrical cavity 11, and the cold air in the electrical cavity 11 enters the fan 3 through the air inlet 12 of the fan 3.

[0031] The electrical cavity 11 is equipped with a control circuit board 13, which is electrically connected to the fan 3. When the rice cooker is cooking rice, the control circuit board 13 controls the fan 3 to work so as to blow out the hot air bubbles piled up on the exhaust port 2.

[0032] The inner pot 1 is covered with an inner cover 14, which has several through holes 15. The inner pot 1 is connected to the exhaust port 2 through the through holes 15. The top cover 10 is provided with an exhaust hole 16 that connects to the outside. The exhaust port 2 is connected to the exhaust hole 16. When the rice cooker is cooking rice, the hot air bubbles generated by the inner pot 1 will pile up and then gradually enter the exhaust port 2 through the through holes 15 and pile up on the exhaust port 2. The cold air blown out by the fan 3 will break the hot air bubbles piled up on the exhaust port 2. In addition, the hot steam generated by the inner pot 1 will also enter the exhaust port 2 through the through holes 15 and then be discharged to the outside through the exhaust hole 16. The cold air entering the exhaust port 2 will also be discharged back to the outside through the exhaust hole 16. The cold air can promote the discharge of hot steam to the outside.
