Description

Technical Field

[0001] The utility model relates to the field of cookers such as rice cookers or pressure cookers, and particularly relates to a noise reduction device for a cooker body. Background Art

[0002] For most pressure cookers on the market, the pressure relief device directly discharges the pressure inside the pot to the outside of the pot. In this way, the noise during pressure relief is very large, and there are certain operation risks. Content of the Utility Model

[0003] To solve the above problems, the present technical solution provides a noise reduction device for a cooker body.

[0004] To achieve the above object, the present technical solution is as follows:

[0005] A noise reduction device for a cooker body includes at least:

[0006] A sound insulation cover is arranged on the cooker body and surrounds the outer periphery of the pressure relief valve. A sound insulation cover is also arranged on the sound insulation cover;

[0007] A water collection box assembly is arranged on the cooker body and is communicated with the pressure relief valve through a communication hole.

[0008] In some embodiments, the water collection box assembly includes:

[0009] A bottom cover, the bottom cover is fitted with an upper cover. The upper cover is provided with an air inlet hole opposite to the communication hole, and the upper cover is provided with an exhaust hole for discharging the water vapor after noise reduction.

[0010] In some embodiments, the bottom cover is provided with a buckle, and the upper cover is provided with a clamping step for cooperating with the buckle.

[0011] In some embodiments, the sound insulation cover is detachably connected to the cooker body.

[0012] In some embodiments, an entry groove is arranged on the outer periphery of the sound insulation cover. A fixing groove is arranged on one side of the entry groove. The cooker body is also provided with a clamping block. The clamping block first enters the entry groove and then the sound insulation cover is rotated so that the clamping block cooperates with the fixing groove.

[0013] In some embodiments, a sealing ring is also sleeved on the communication hole.

[0014] The beneficial effects of the present application are:

[0015] When the pressure cooker is working, the lid assembly is closed, forming a closed cooking space with the main body assembly. Steam with a certain pressure will be generated inside the pot. When an external force pushes the pressure relief valve to displace and move away from the exhaust pipe, the pressure inside the pot will be discharged outside the pot. At this time, if the sound insulation cover and the water collection box are not installed and the pressure relief valve is in the open state, the steam inside the pot can be discharged outside the pot at will, resulting in a lot of noise. If the sound insulation cover and the water collection box are installed properly and the pressure relief valve is in the semi-open state, the steam inside the pot needs to pass through the inside of the sound insulation cover and the water collection box and then be discharged outside the pot, and the noise will be greatly reduced.

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following further details the present invention with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Please refer to Figure 1-2 as shown, a noise reduction device for a pot body, at least including;

[0023] An exhaust pipe 600, one end of which extends into the inner liner of the pot body, and the other end extends out of the pot body and communicates with the outside;

[0024] A pressure relief valve 700, which is located at the other end of the exhaust pipe 600 and can move on the exhaust pipe 600 to block or open the port at the other end of the exhaust pipe 600;

[0025] A jacking structure 800, connected to the pressure relief valve 700, for pushing the pressure relief valve 700.

[0026] In this application, the pressure relief valve is pushed by the jacking structure and then moves away from the exhaust valve, so as to connect the exhaust valve with the outside for exhaust, thus replacing the solenoid valve, greatly reducing the volume of the device, increasing the adaptability to the working environment, and being more reliable and durable.

[0027] In this embodiment, the jacking structure 800 includes;

[0028] A jacking base 801;

[0029] A jacking upper cover 802, which cooperates with the jacking base 801 and has a limiting movable part 803;

[0030] A jacking rod 804, which is arranged in the limiting movable part 803 and is used to jack up the pressure relief valve 700;

[0031] A jacking driving part 805, which is located above the jacking base 801 and is provided with a guiding inclined surface 806. The jacking rod 804 is located above the guiding inclined surface 806. As the jacking driving part 805 works, the guiding inclined surface 806 is used to lift the jacking rod 804.

[0032] Since the jacking rod is limited by the limiting movable part, it can only move up and down. Under the rotational action of the jacking driving part, the inclination of the guiding inclined surface is used to push the jacking rod to move up and down. When it is pushed upward, it can push the pressure relief valve away from the exhaust pipe, thereby opening the exhaust. When it moves downward, the pressure relief valve approaches the exhaust valve by gravity, thereby blocking the exhaust pipe.

[0033] In this embodiment, the jacking structure 800 further includes;

[0034] A rack is provided on the outer periphery of the jacking driving part 805. The rack is meshed and connected with a driving wheel 807, and the driving wheel 807 is connected with a driver 808;

[0035] The jacking driving part 805 is rotatably arranged on the jacking base 801. The guiding inclined surface 806 is wound around the outer periphery of the jacking driving part 805 and is designed in a slope shape;

[0036] When the driver works, it drives the driving wheel, then drives the jacking driving part to rotate, and then uses the guiding inclined surface designed in a slope shape to drive the jacking rod to move up and down.

[0037] In this embodiment, the jacking rod 804 is provided with a limiting stop piece 809 that cooperates with the limiting movable part 803 to prevent the jacking rod from detaching.

[0038] In this embodiment, a spring 810 is arranged between the shaft body of the jacking rod 804 and the inner cavity of the limiting movable part 803, and the spring force is used for resetting when the jacking rod falls.

[0039] In this embodiment, a first microswitch 811 is provided on the top base 801 in the forward rotation direction of the jacking drive unit 805, and a second microswitch 812 is provided in the reverse rotation direction of the jacking drive unit 805 to prevent the jacking drive unit from rotating excessively and causing the jack rod to disengage from the guiding inclined surface.

[0040] In this embodiment, an insertion portion 701 for extending into the port of the exhaust pipe 600 for plugging is provided at the upper end of the pressure relief valve 700, which is used to insert into the port of the exhaust pipe for plugging. Conversely, when the pressure relief valve disengages, exhaust is carried out.

[0041] In this embodiment, an air outlet hole 702 communicating with the exhaust pipe 600 is provided on the outside of the insertion portion 701 of the pressure relief valve 700.

[0043] A sound insulation cover 900 is provided on the pot body and surrounds the outer periphery of the pressure relief valve 700. A sound insulation cover 901 is also provided on the sound insulation cover 900;

[0044] A water collection box assembly 902 is provided on the pot body and communicates with the pressure relief valve 700 through a communication hole.

[0045] When the exhaust pipe of this application discharges gas, it pushes the pressure relief valve away. At this time, seen from Figure 4 above, after the gas is noise-reduced by the sound insulation cover, it is discharged from the through hole of the sound insulation cover. In this way, the noise is greatly reduced. Another part of the gas flows between the outer wall of the pressure relief valve and the inner wall of the sound insulation cover and enters the water collection box assembly through the communication hole for noise reduction, and then is also discharged from the water collection box assembly, forming two noise reduction processes.

[0046] In this embodiment, the water collection box assembly 902 includes;

[0047] A bottom cover 903, the bottom cover 903 is fitted with an upper cover 904. The upper cover 904 is provided with an air inlet hole 905 opposite to the communication hole, and the upper cover 904 is provided with an exhaust hole 906 for discharging the water vapor after noise reduction. The gas enters the water collection box through the air inlet hole, and then is noise-reduced by the water in the water collection box, and finally is discharged from the exhaust hole.

[0048] In this embodiment, the bottom cover 903 is provided with a buckle 907, and the upper cover 904 is provided with a clamping step 908 cooperating with the buckle 907. The buckle and the step are quickly clamped and assembled to improve the assembly efficiency.

[0049] In this embodiment, the sound insulation cover 900 is detachably connected to the pot body.

[0050] In this embodiment, an entry groove 909 is provided on the outer periphery of the sound insulation cover 900. A fixing groove 910 is provided on one side of the entry groove 909. The sound insulation cover further includes a clamping block 911 provided on the pot body. The clamping block 911 first enters the entry groove 909 and then by rotating the sound insulation cover 900, the clamping block 911 is engaged with the fixing groove 910 to place the sound insulation cover on the pot body, and then the two are assembled by rotation, with higher assembly efficiency.

[0051] In this embodiment, a sealing ring 912 sleeved on the communication hole is further included.

[0052] The above are only the preferred embodiments of the present application and are not used to limit the scope of implementation of the present application. All other embodiments with the same or similar principles and basic structures as the present application are within the protection scope of the present application.
