Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a cooking cup and a food processor with an anti-overflow structure. Background Art

[0002] The heating food processors on the market, such as wall breaking machines and soy milk machines, are prone to generate a large number of bubbles when making soy milk, which may overflow in serious cases. In order to solve the problem of overflow during food heating in existing products such as wall breaking machines and soy milk machines, an overflow prevention device is usually provided in the food processor. When the bubbles contact the overflow prevention device, the control unit of the food processor generates a signal to stop heating the heating body and no longer generate bubbles, thereby preventing overflow.

[0003] For example, Chinese patent CN102217898B discloses an anti-overflow structure on the stirring cup cover, in which the anti-overflow probe is suspended in the air and inserted into the stirring cup. The anti-overflow probe is used as a signal, and heating is stopped when bubbles hit the anti-overflow probe. In this structure, the anti-overflow probe is set on the stirring cup cover, one end is fixed to the stirring cup cover, and the other end is inserted into the stirring cup. For another example, Chinese patent CN202234798U discloses an anti-overflow probe structure on the side wall of the stirring cup, and the anti-overflow probe is set on the side of the stirring cup.

[0004] In the prior art, whether the anti-overflow probe is set on the blending cup cover or in the blending cup, the anti-overflow probe is set vertically. This structure needs to ensure that there is a sufficient height distance between the anti-overflow probe and the steam outlet of the blending cup cover to prevent bubbles from overflowing due to residual heat. However, the large height distance between the anti-overflow probe and the steam outlet of the blending cup cover not only makes the product's external dimensions too large, but also affects the space utilization of the blending cup.

[0027] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0028] like Figure 1 In the embodiment shown, the food processor disclosed in the present invention comprises a main unit 1 and a cooking cup used in combination with the main unit 1. The main unit 1 is provided with a control circuit board 11; the cooking cup comprises a cup body 2 having a cup cavity 21 and a cup cover 3 covering the cup body 2, the cup body 2 is provided with an electric heating element 23 controlled by the control circuit board 11 to heat the food in the cup cavity 21; the cup cover 3 is provided with an anti-overflow structure, and when bubbles are detected, the anti-overflow structure generates an anti-overflow electrical signal and outputs it to the control circuit board 11, and the control circuit board 11 controls the electric heating element 23 to stop heating to prevent the food in the cup cavity 21 from overflowing from the cup cover 3, thereby achieving the purpose of anti-overflow.

[0029] Further integration Figure 1-Figure 5 The cup cover 3 includes a cup cover body 31 with a center hole 32, a first anti-overflow channel 33 arranged on the cup cover body 31, and an anti-overflow probe 36 for generating an anti-overflow electrical signal, the anti-overflow probe 36 is arranged in the first anti-overflow channel 33, and the lower end of the first anti-overflow channel 33 is provided with an air vent 34 connected to the center hole 32, and the first anti-overflow channel 33 is spirally extended gradually upward from the air vent 34.

[0030] The cooking cup disclosed in the present invention adopts an anti-overflow structure that combines an anti-overflow probe 36 with an ascending spiral first anti-overflow channel 33. The ascending spiral first anti-overflow channel 33 can have a long extension length within a limited height, ensuring that after the bubbles enter the first anti-overflow channel 33 from the central hole 32 through the air vent 34, the bubbles are allowed to climb upward along the first anti-overflow channel 33 that spirals and gradually extends upward under the action of inertia, and the bubbles are gradually dissolved during the climbing process. The dissolved bubble liquid gradually flows downward along the first anti-overflow channel 33 back into the cup cavity 21 without accumulating and blocking in the first anti-overflow channel 33, thereby ensuring the anti-overflow reliability of the anti-overflow structure. It can be seen that the present invention can reduce the height requirement of the anti-overflow structure on the cooking cup by improving the structure of the first anti-overflow channel 33, which is conducive to reducing the external dimensions of the cooking cup and effectively utilizing the space of the cooking cup.

[0031] In one embodiment, a probe mounting position 35 is provided in the first anti-overflow channel 33, and the anti-overflow probe 36 is fixed at the probe mounting position 35, and the probe mounting position 35 is arranged close to the air leakage port 34 so that the anti-overflow probe 36 can sense the bubbles and generate an anti-overflow electrical signal in the first time, which is beneficial to improve the anti-overflow effect.

[0032] Preferably, the probe installation position 35 is arranged to extend transversely to the air leakage port 34, and the anti-overflow probe 36 is transversely fixed to the air leakage port 34. This structure not only enables the anti-overflow probe 36 to quickly sense bubbles and generate anti-overflow electrical signals, but also reduces the overall height of the anti-overflow structure in the cup cover 3.

[0033] In one embodiment, the width of the first anti-overflow channel 33 is gradually reduced from the air vent 34 upwards, which is beneficial for the bubbles to be squeezed continuously during the rising process in the first anti-overflow channel 33, thereby improving the defoaming ability through squeezing, thereby improving the anti-overflow effect.

[0034] In one embodiment, the first anti-overflow channel 33 is arranged around the central hole 32, and a first barrier rib 37 is arranged between the upper end of the first anti-overflow channel 33 and the air leakage port 34, that is, the first anti-overflow channel 33 starts from the air leakage port 34 and ends at the first barrier rib 37; and the upper end surface of the first anti-overflow channel 33 is open, and a detachable anti-overflow cover 4 is arranged in the central hole 32, and the anti-overflow cover 4 includes a lower cover 41, and the lower cover 41 is covered on the upper end surface of the first anti-overflow channel 33 to close the upper end surface of the first anti-overflow channel 33; the lower cover 41 is provided with an air hole 414, and the air hole 414 is connected to the upper end of the first anti-overflow channel 33. After the bubbles are defoamed during the climbing process in the first anti-overflow channel 33, the bubble liquid gradually flows back to the cup cavity 21 along the first anti-overflow channel 33, and the steam continues to move upward in the first anti-overflow channel 33 and is discharged through the air hole 414. This structure makes it easy to openly set the first anti-overflow channel 33 around the central hole 32, and cooperate with the detachable lower cover 41, so that the first anti-overflow channel 33 can be easily cleaned after the lower cover 41 is removed, which is beneficial to improving the sanitary conditions of use.

[0035] In one embodiment, the anti-overflow cover 4 further includes an upper cover 42 covering the lower cover 41, the upper cover 42 includes an upper cover body 421 having an exhaust port 423; a second anti-overflow channel is provided between the lower cover 41 and the upper cover 42, the second anti-overflow channel gradually extends upward from the air hole 414 to the exhaust port 423 in a spiral shape, and the defoaming channel of the first anti-overflow channel 33 is further extended by the second anti-overflow channel to further improve the anti-overflow capability of the cooking cup. In addition, the second anti-overflow channel is gradually reduced from the air hole 414 to the exhaust port 423 to improve the second anti-overflow channel's ability to squeeze and defoam bubbles.

[0036] Especially see Figure 3 and Figure 4As shown. In one embodiment, the lower cover 41 includes a lower cover body and an inner enclosure 412 disposed in the middle of the lower cover body, the lower cover body having a guide surface 411 with a gradually rising surface height, the guide surface 411 extending around the inner enclosure 412; the air hole 414 is disposed at the lowest position of the guide surface 411, and a second retaining rib 413 is disposed at the highest position of the guide surface 411, and the second retaining rib 413 isolates the lowest position of the guide surface 411 from the highest position of the guide surface 411. The upper cover 42 is detachably assembled in the center hole 32 and is located above the lower cover 41, the exhaust port 423 is directly opposite to the highest position of the guide surface 411, the lower cover 41 provides support for the upper cover 42 through the inner enclosure 412, the inner side wall of the center hole 32, the guide surface 411, the outer side wall of the inner enclosure 412 and the upper cover 42 together enclose the second anti-overflow channel, and the exhaust port 423 is connected to the second anti-overflow channel. It can be seen that, since the upper cover 42 and the lower cover 41 are a detachable connection structure, the second anti-overflow channel is also a detachable structure, which makes it easy to disassemble the upper cover 42 to clean the second anti-overflow channel.

[0037] The air holes 414 are configured as one or more circular holes, or one or more long strip holes, so that bubbles are squeezed or blocked when passing through the air holes 414 to cause the bubbles to burst, thereby improving the anti-overflow effect.

[0038] A buckle position 422 is provided on the circumferential side of the upper cover body 421, and a buckle 311 is correspondingly provided on the inner wall of the cup cover body above the center hole 32. The upper cover 42 is buckled with the buckle position 422 at the corresponding position through the buckle 311, so that it can be detachably assembled in the center hole 32.

[0039] Recombination Figure 1 and Figure 5As shown. The food processor of this embodiment is a food processor, a wall-breaking machine or a soybean milk machine. A stirrer 25 is provided in the cup body 2, and the stirrer 25 includes a stirring shaft and a stirring blade provided on the stirring shaft; an upper coupler 23 electrically connected to the anti-overflow probe 36 and an upper connector 24 fixedly connected to the stirring shaft are provided at the outer bottom of the cup body 2; a motor 12 electrically connected to the control circuit board 11 is provided in the host 1, and a lower coupler 13 electrically connected to the control circuit board 11 and a lower connector 14 fixedly connected to the rotating shaft of the motor 12 are provided on the upper end surface of the host 1. When the food processor is assembled on the host 1, the lower coupler 13 is coupled and connected with the upper coupler 23 to transmit the anti-overflow electrical signal generated by the anti-overflow probe 36 to the control circuit board 11, and the food processor is coupled and connected with the lower connector 14 through the upper connector 24, so that the motor 12 drives the stirrer 25 to rotate, and the stirrer 25 is used to stir and break the food in the cup cavity 21 of the cup body 2. By arranging the cooking cup to be detachable from the main unit 1 , the user can take the cooking cup separately, thereby facilitating the user's use.

[0040] In one embodiment, a conductive member 39 is provided on the cup cover body 31 and is electrically connected to the anti-overflow probe 36 directly or through a first conductive wire 38; a cup handle 22 is provided on the outer side surface of the cup body 2 for easy operation by the user, and an elastic contact 223 is provided on the upper end surface of the cup handle 22, and a second conductive wire 221 electrically connected between the elastic contact 223 and the upper coupler 23 is provided in the cup handle 22; when the cup cover 3 is closed on the cup body 2, the conductive member 39 is electrically connected to the elastic contact 223, so that the anti-overflow electrical signal generated by the anti-overflow probe 36 is transmitted to the control circuit board 11 through the conductive member 39, the elastic contact 223, the upper coupler 23 and the lower coupler 13, so that the control circuit board 11 can be used to control the operation of the electric heating element 23.

[0041] Figure 1 In the embodiment shown, the cooking cup and the main machine 1 are in an upper and lower structure. Of course, the food processor may also be in other structural forms. Figure 6 and Figure 7 In the embodiment shown, the main unit 1 and the cooking cup are in a horizontal structure. The main unit 1 has a housing with a side opening on one side, and the cooking cup is arranged in the housing and can be taken out from the side opening; the elastic contact 223 (at the bottom of the top shell 19 of the housing) electrically connected to the control circuit board 11 is provided. Figure 6 and Figure 7When the cooking cup is mounted on the main unit 1 through the side opening of the housing, the elastic contact 223 is electrically connected to the conductive member 39 on the cup cover 3, so that the anti-overflow electrical signal generated by the anti-overflow probe 36 is transmitted to the control circuit board 11 in the main unit 1 through the conductive member 39 and the elastic contact 223.

[0042] The food processor disclosed in the present invention has the first anti-overflow channel in the cup cover 3 and the second anti-overflow channel in the anti-overflow cover. Both the first anti-overflow channel and the second anti-overflow channel are upward spiral structures, and both are provided with a height difference. The lowest point is the bubble inlet, which is not only convenient for blocking the inertia of the bubble, but also conducive to backflow. The working principle of realizing anti-overflow is as follows:

[0043] When the cup cavity 21 of the cup body 2 generates a large number of bubbles after heating, the bubbles will first enter the air vent 34 through the central hole 32. When the bubbles contact the anti-overflow probe 36, the control circuit board 11 will receive the corresponding anti-overflow electrical signal, and the control circuit board 11 will control the electric heating element 23 to stop heating. Although the electric heating element 23 is powered off and stops heating, the bubbles will climb upward again due to the residual heat of the electric heating element 23 and its own inertia. At this time, the bubbles will enter the first anti-overflow channel from the air vent 34 and climb upward along the first anti-overflow channel. Because the spiral structure of the first anti-overflow channel will give the bubbles a certain resistance to climbing, the bubbles will lose the inertial kinetic energy of upward movement during the climbing process and will be continuously squeezed and melted. Even if a small number of bubbles do not break, they will enter the second anti-overflow channel from the air hole 414. The bubbles will continue to climb in the second anti-overflow channel under the climbing inertia and continue to break and finally melt completely, achieving the anti-overflow effect of preventing the foam from overflowing through the exhaust port 423. The bubble liquid generated by the rupture flows back into the cup cavity 21 along the second anti-overflow channel and the first anti-overflow channel under the action of gravity.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
