Description

Technical Field

[0001] The utility model belongs to the technical field of food processors.

Background Art

[0002] In the existing air outlet structure of the blender cup lid, it is arranged at the bottom of the cup lid. The air flow is an axial channel air outlet structure or a multi-angle turning air outlet structure. The axial channel air outlet structure has a relatively fast air flow speed, resulting in a relatively concentrated noise at the air outlet holes, thus making the noise at the air outlet holes relatively large. The multi-angle turning air outlet structure combines the axial and transverse air outlet channels. The air flow passes through multiple turning structures to reduce the air flow speed, thereby achieving the effect of reducing noise.

[0003] The Chinese invention patent application with the publication number of CN 113243782 A discloses a food processor with good noise reduction effect, including a main body, a motor and a stirring cup. A crushing knife driven by the motor is arranged in the stirring cup. The stirring cup includes a cup body and a cup lid covering the upper part of the cup body. The cup lid and the cup body enclose a crushing cavity. An opening is arranged on the cup lid, and a noise reduction lid with a hollow inner cavity is arranged at the opening. The noise reduction lid is sealed with the opening. The noise reduction lid is provided with an air inlet hole communicating the inner cavity with the crushing cavity and an air outlet hole communicating the inner cavity with the outside. The equivalent inner diameter of the air inlet hole is D1, and the equivalent inner diameter of the inner cavity is D2, where 0.03 ≤ D1 / D2 ≤ 0.2. The hollow inner cavity does not block the air flow. The air flow quickly enters the inner cavity and is discharged from the air outlet hole, thereby quickly releasing the air pressure in the stirring cup and playing an anti-overflow effect. By controlling the equivalent inner diameters of the air inlet hole and the inner cavity, the sound energy in the air flow is quickly released after entering the inner cavity, the amplitude of the sound wave is reduced, and the sound intensity is decreased, thereby achieving the noise reduction effect.

[0004] However, in the prior art, an opening structure is arranged at the center of the bottom of the cup lid. After the ingredients in the cup body undergo high-speed centrifugal motion, the ingredients quickly adsorb to the cup wall. When the stirring stops, the ingredients adsorbed on the cup wall quickly move closer to the center and are easily adsorbed on the central part of the bottom of the cup lid. If there is an opening structure at the center of the bottom of the cup lid, the ingredients are likely to gather at the central opening, easily causing problems such as overflow of the slurry.

Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a food processor with an air outlet structure, which can reduce the exhaust noise and solve the problem of overflow of the slurry.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A food processor with an air outlet structure, comprising a main body and a mixing cup. The main body is provided with a motor, the bottom of the mixing cup is provided with a heating plate, and a crushing knife is arranged in the mixing cup. The motor drives the crushing knife to rotate. The mixing cup includes a cup body and a cup cover buckled to the mouth of the cup body. A concave cavity is formed by protruding downward at the center of the cup cover, and a buckling cover is buckled on the concave cavity. An air inlet hole is arranged on the side wall of the concave cavity, and an air outlet hole is arranged on the buckling cover. The air inlet hole and the air outlet hole are spaced at a set angle in the circumferential direction, and an air flow reflection structure is arranged between the air inlet hole and the air outlet hole to reflect and decelerate the air flow during the flowing process.

[0008] Preferably, the circumferential spacing angle between the air inlet hole and the air outlet hole is α, 90° ≤ α ≤ 180°; and / or, the air flow reflection structure includes a first air flow reflection surface correspondingly arranged on the inner side wall of the concave cavity opposite to the air inlet hole.

[0009] Preferably, the air outlet hole is arranged in the area near the edge of the buckling cover.

[0010] Preferably, the air outlet hole is a penetrating structure with different directions of the air inlet end and the air outlet end.

[0011] Preferably, the air outlet hole includes an axial section with an upper end opening and a bottom closed by a baffle, and a radial inlet arranged on the outer side of the lower part of the axial section in the radial direction. The air flow reflection structure includes a second air flow reflection surface arranged on the bottom surface of the baffle.

[0012] Preferably, an overflow hole is arranged on the bottom side of the concave cavity, and the overflow hole and the air inlet hole are spaced at a set angle in the circumferential direction.

[0013] Preferably, the concave cavity includes a circular arc bottom, a middle cylinder, and a circular arc transition structure arranged between the circular arc bottom and the middle cylinder.

[0014] Preferably, the air inlet hole is arranged at the middle height position of the side wall of the middle cylinder, and the distance H from the bottom surface of the circular arc bottom is H ≥ 5 mm.

[0015] Preferably, the concave cavity further includes an upper cylinder, the diameter of the upper cylinder is larger than that of the middle cylinder, and a circular arc transition structure is arranged between the upper cylinder and the middle cylinder. The cup cover is provided with a circular ring concave cavity protruding downward around the upper cylinder.

[0016] Preferably, the buckling cover is buckled and fixed to the cup cover through a buckle structure.

[0017] The utility model adopts the above technical solutions and has the following beneficial effects:

[0018] 1. The motor drives the crushing knife to perform high-speed stirring and crushing motion. Due to the high-speed motion and the heating plate built into the bottom of the stirring cup, noise is generated by the high-speed rotation and steam generated by heating the ingredients flows upward.

[0019] Since the air inlet hole is provided on the side wall of the concave cavity, rather than the bottom wall, the bottom wall also has the function of air flow reflection. That is, a considerable part of the sound waves and steam generated by stirring are reflected by the air flow on the bottom wall and then transmitted through the air inlet hole, reducing the noise to a certain extent. Then, during the flow from the air inlet hole to the air outlet hole, the air flow reflection structure between the air inlet hole and the air outlet hole enables the air flow to be reflected and decelerated multiple times during the flow process, and then discharged along the air outlet hole. This effectively weakens the frequency of the sound waves generated by stirring, and after multiple reflections and decelerations, the air flow shows a stepped weakening, thereby further reducing the noise and achieving the purpose of reducing the noise formed by the air flow speed and air flow impact.

[0020] In addition, the bottom of the concave cavity is a closed structure, so the suspended substances generated by stirring and boiling are not easily adsorbed on the bottom or the air inlet hole, and thus it is not easy for the suspended substances to block the air inlet hole, thereby well solving the problem of slurry overflow.

[0021] 2. Since the air flow reflection structure includes a first air flow reflection surface provided on the inner side wall of the concave cavity corresponding to the opposite side of the air inlet hole, it can well reflect the air flow of the air inlet hole to a certain extent. And since the circumferential interval angle between the air inlet hole and the air outlet hole is α, 90° ≤ α ≤ 180°, in this way, most of the air flow entering from the air inlet hole will not directly discharge from the air outlet hole, but is reflected and decelerated by the first air flow reflection surface, which is beneficial to reducing the noise to the greatest extent.

[0022] 3. Since the air outlet hole is provided in the area near the edge of the buckle cover, the top wall of the buckle cover can also play a role in reflecting and decelerating the air flow.

[0023] 4. The air outlet hole is a plug-through structure with different directions of the air inlet end and the air outlet end, which can further reduce the noise and overflow problems caused by air flow impact.

[0024] 5. The second air flow reflection surface will form a certain reflection effect on the air flow. After the air flow passes through the baffle, its air flow is weakened, and then after passing through the radial inlet, its air flow is weakened for the second time. Finally, after passing through the air outlet hole, its air flow undergoes multiple decelerations, and the air flow speed is greatly reduced, thereby reducing the noise of air flow impact.

[0025] 6. The overflow hole facilitates the cold liquid that enters from the air inlet hole and remains in the concave cavity to flow out. Since the overflow hole and the air inlet hole are spaced at a set angle in the circumferential direction, the mutual influence between the overflow hole and the air inlet hole can be avoided.

[0026] 7. The bottom of the arc can well block the impact of the airflow, and the airflow passing through the bottom of the arc can form a certain reflection, so as to well reduce the airflow speed. At the same time, with the arc-shaped bottom set at the bottom, it is not easy for the food suspension to adsorb.

[0027] 8. Since the distance H from the air inlet hole to the bottom surface of the arc bottom is H≥5mm, it is not easy for the suspension to block the air inlet hole, thus well solving the problem of slurry overflow.

[0028] 9. Since the diameter of the upper cylinder is larger than that of the middle cylinder, the concave cavity is a stepped structure, which is conducive to forming an airflow reflection structure in the concave cavity, and setting the circular ring concave cavity can limit the upward convex height of the concave cavity.

[0029] 10. The buckle cover is buckled and fixed with the cup cover through the buckle structure, so that it is convenient to remove the buckle cover and clean the inside of the concave cavity.

[0030] These features and advantages of the present utility model will be detailedly disclosed in the following specific embodiments and drawings.

[0046] As Figures 1 to 8 shown, the present utility model provides a food processor, which includes a main body 1 and a mixing cup assembly 0. The mixing cup assembly 0 includes a mixing cup 14 and a crushing knife 18 disposed inside the mixing cup. The main body 1 is provided with a motor. A heating plate assembly 15, a cup base 16 and a heat insulation sleeve 17 are disposed at the bottom of the mixing cup, and the motor drives the crushing knife to rotate. The mixing cup 14 includes a cup body and a cup cover 12 buckled to the mouth of the cup body. A cup cover sealing ring 13 is installed on the cup cover 12 to achieve sealing with the cup body.

[0047] In this embodiment, a concave cavity protruding downward is provided at the center of the cup cover 12, and a buckle cover 11 is buckled on the concave cavity. An air inlet hole 1201 is provided on the side wall of the concave cavity, and an air outlet hole 1101 is provided on the buckle cover 11. The air inlet hole 1201 and the air outlet hole 1101 are spaced at a set angle in the circumferential direction, and an air flow reflection structure for reflecting and decelerating the air flow during the flowing process is provided between the air inlet hole 1201 and the air outlet hole 1101.

[0048] It can be understood that multiple air flow reflection structures can be provided on the air flow path to enable the air flow to be reflected and decelerated multiple times during the flowing process.

[0049] The motor drives the crushing knife to perform high-speed stirring and crushing motion. Due to the high-speed motion and the heating plate built in the bottom of the mixing cup, the noise generated by the high-speed rotation and the steam generated by heating the food materials flow upward.

[0050] Since the air inlet hole is provided on the side wall of the concave cavity instead of the bottom wall, the bottom wall also has the function of air flow reflection, that is, a considerable part of the sound waves and steam generated by stirring are reflected by the air flow on the bottom wall and then transmitted through the air inlet hole, reducing the noise to a certain extent; then, during the flowing process from the air inlet hole to the air outlet hole, the air flow reflection structure between the air inlet hole and the air outlet hole enables the air flow to be reflected and decelerated multiple times during the flowing process, and then discharged along the air outlet hole, effectively weakening the frequency of the sound waves generated by stirring. After multiple reflections and decelerations, the air flow shows a step-by-step weakening, thereby further reducing the noise and achieving the purpose of reducing the noise formed by the air flow speed and the air flow impact.

[0051] In addition, the bottom of the concave cavity is a closed structure 120502. The suspended substances generated by stirring and boiling are not easily adsorbed on the bottom or the air inlet holes, so it is not easy for the suspended substances to block the air inlet holes, thus well solving the problem of slurry overflow.

[0052] Preferably, the air outlet hole 1101 is arranged in the region near the edge of the cover 11, which can also play a certain role in reflecting and reducing the speed of the air flow on the top wall of the cover. At the same time, the circumferential interval angle between the air inlet hole 1201 and the air outlet hole 1101 is α, 90° ≤ α ≤ 180°, for example, 180°. The air flow reflection structure includes a first air flow reflection surface 1204 provided on the inner side wall of the concave cavity corresponding to the opposite side of the air inlet hole, which can well reflect the air flow of the air inlet hole. In this way, most of the air flow entering from the air inlet hole will not directly discharge from the air outlet hole, but is reflected and decelerated by the first air flow reflection surface, which is beneficial to reducing the noise to the greatest extent.

[0053] Furthermore, in order to make the air flow pass through multiple reflections from the air inlet hole to the air outlet hole, so as to solve problems such as reducing the air flow speed and the noise formed by the air flow impact. The air outlet hole 1101 is a plug-through structure with different directions of the air inlet end and the air outlet end. It can further reduce the noise and overflow problems brought by the air flow impact. Specifically, the air outlet hole 1101 includes an axial section with an upper end opening and a bottom provided with a baffle 1103 for closing, and a radial inlet 1102 provided on the radially outer side of the lower part of the axial section. The air flow reflection structure further includes a second air flow reflection surface provided on the bottom surface of the baffle, which will form a certain reflection effect on the air flow. In addition, the bottom surface of the air outlet hole 1101 facing the radial inlet 1102 is equivalent to having a third air flow reflection surface. Therefore, the air flow is weakened after passing through the baffle 1103, and then weakened again after passing through the radial inlet 1102. Finally, it is discharged through the air outlet hole 1101. Its air flow passes through multiple decelerations, and the air flow speed is greatly reduced, thus reducing the noise of the air flow impact.

[0054] Specifically, the concave cavity includes an arc bottom 1202, a middle cylinder 1206, and an arc transition structure 1203 provided between the arc bottom and the middle cylinder. The air inlet hole 1201 is provided at the middle height position of the side wall of the middle cylinder, and the distance H from the bottom surface of the arc bottom is H≥5 mm. The arc bottom 1202 can well block the impact of the airflow, and the airflow can form a certain reflection after passing through the arc bottom 1202, so as to well reduce the airflow speed. At the same time, with the arc bottom 1202 provided at the bottom, it is not easy for the food suspension to adsorb. Since the distance H from the air inlet hole to the bottom surface of the arc bottom is H≥5 mm, it is not easy for the suspension to block the air inlet hole, thus well solving problems such as slurry overflow. The concave cavity further includes an upper cylinder 1207. The diameter of the upper cylinder is larger than that of the middle cylinder 1206, and there is an arc transition structure between the upper cylinder and the middle cylinder. The cup cover 12 is provided with a circular ring concave cavity 1208 protruding downward around the upper cylinder 1207 to limit the upward protruding height of the concave cavity. Since the diameter of the upper cylinder is larger than that of the middle cylinder, the concave cavity is a stepped structure, which is beneficial to form an airflow reflection structure in the concave cavity.

[0055] Further, an overflow hole 1205 is provided on the bottom side of the concave cavity. The overflow hole 1205 facilitates the cold liquid that enters from the air inlet hole and remains in the concave cavity to flow out. The overflow hole 1205 and the air inlet hole 1201 are spaced at a set angle in the circumferential direction. Specifically, the overflow hole 1205 is provided at a position 90 degrees to the air inlet hole to avoid mutual influence between the overflow hole and the air inlet hole. The overflow hole 1205 is provided in the arc transition structure 1203.

[0056] Further, the overflow hole 1205 is also provided with an insertion-through structure. Specifically, a baffle 120501 is provided above the overflow hole 1205. The baffle has a certain blocking effect on the suspension, which can prevent larger pieces of suspension from entering the concave cavity through the overflow hole 1205. The liquid formed after the airflow condenses flows out along the overflow hole 1205, and the baffle can also block the airflow and has a noise reduction effect on the gas passing through the overflow hole.

[0057] Such as Figure 6 and Figure 7 As shown, the buckle cover 11 is provided with a plurality of buckle structures and is buckled together with the cup cover 12. In this way, it is convenient to remove the buckle cover 11 and clean the inside of the concave cavity.

[0058] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
