Description

Technical Field

[0001] The present application relates to the technical field of food processors, and specifically to a food processor with a heating function. Background Art

[0002] A food processor is a multifunctional kitchen appliance primarily used for making Chinese and Western pastries, offering functions such as kneading, beating eggs, and stirring. Its internal drive mechanism transmits stirring force, significantly improving production efficiency and reducing labor intensity. It is particularly suitable for baking and cooking, which require frequent stirring and mixing. A food processor can knead dough, helping it quickly form a dough ball and form a film, significantly saving time. It can also beat eggs and stir, resulting in a more delicate and smooth result than manual whipping. By replacing various accessories, a food processor can also perform various functions, such as juicing, mincing meat, stuffing sausages, and chopping vegetables.

[0003] In order to withstand long-term use and high-intensity work, food processors generally use metal materials to make the mixing bowl. Metal materials have good thermal conductivity and can carry away the heat generated when the ingredients are stirred. Especially in low ambient temperatures such as winter, metal mixing bowls can cause the temperature of the ingredients inside the bowl to be low, making it difficult for the ingredients to ferment, affecting the efficiency and effectiveness of the food preparation.

In this technical solution, the heating element is directly fitted with the mixing drum for use, and the heating element needs to have a sturdy protective shell to avoid frequent contact with the mixing drum, which may cause damage to the heating element or leakage of electricity, thereby increasing the cost of using the heating element. In addition, there is no buffer when the heating element contacts the mixing drum, and excessive impact may also cause deformation and damage to the heating element or the mixing drum.

[0034] Refer to the following Figure 1-4 A food processor with a heating function is described according to some embodiments of the present application.

[0035] A chef machine with heating function, as shown in the following Figure 1-3 As shown, the mixing bowl 1 and the machine body 2 are provided with a base 3 on the machine body 2, and a heating component 4 is provided in the base 3. When the mixing bowl 1 is placed on the base 3, the heating component 4 contacts the bottom of the mixing bowl 1 and heats it, thereby providing corresponding heat to the ingredients in the mixing bowl 1, promoting the mixing, whipping and fermentation of the ingredients, and improving the efficiency and effect of the production.

[0036] In the technical solution of the present embodiment, a concave cavity 31 is provided in the base 3, and the heating component 4 is arranged in the concave cavity 31. An elastic element and a limiting structure are provided between the heating component 4 and the concave cavity 31. The heating component 4 can move up and down in the concave cavity 31 under the joint action of the elastic element and the limiting structure. When the ingredients in the mixing bowl 1 are different and have different weights, the elastic force of the elastic element can be used to keep the heating component 4 in close contact with the bottom of the mixing bowl 1, thereby improving the heating efficiency and uniformity. When the mixing bowl 1 is placed in the base 3, the heating component 4 can be retracted accordingly to offset the impact caused by the placement of the mixing bowl 1, thereby preventing the mixing bowl 1 and the heating component 4 from being deformed and damaged by excessive impact.

[0037] Specifically, heating assembly 4 includes a heat-conducting frame 41 and a heating wire 42. The upper surface of heat-conducting frame 41 is shaped to match the bottom of mixing bowl 1. Heating wire 42 can be a conventional electric heating wire, secured to the lower surface of heat-conducting frame 41 via a simple installation method such as clip-on or hoisting. When energized, heating wire 42 heats heat-conducting frame 41, which then evenly and directly conducts the heat to the bottom of mixing bowl 1, thereby heating the ingredients within. Because heating wire 42 does not directly contact the bottom of mixing bowl 1, it does not require an additional, robust protective casing due to frequent contact with the bottom of mixing bowl 1, reducing the cost of using heating wire 42.

[0038] As attached Figure 4-7As shown, in the technical solution of this embodiment, a spring seat 411 is provided on the lower surface of the heat-conducting frame 41. The elastic element is a spring 412 disposed on the spring seat 411. One end of the spring 412 abuts the lower surface of the heat-conducting frame 41, and the other end abuts the upper surface of the cavity 31. When the heat-conducting frame 41 is subjected to the weight of the mixing bowl 1, the spring 412 is compressed. The elastic force under compression can not only offset the impact of the mixing bowl 1 on the heating assembly 4, thereby preventing the mixing bowl 1 and the heating assembly 4 from being deformed and damaged by excessive impact, but also promote the heat-conducting frame 41 to maintain a close fit with the bottom of the mixing bowl 1, thereby improving the efficiency and uniformity of heat conduction of the heat-conducting frame 41.

[0039] In the technical solution of this embodiment, the limiting structure includes a screw seat 413 disposed on the lower surface of the heat-conducting frame 41. There is at least one screw seat 413, and a screw hole 311 corresponding to the screw seat 413 is provided on the upper surface of the cavity 31. When the mixing bowl 1 is not placed in the base 3, the heating component 4 is pushed upward by the elastic force of the spring 412. A screw 415 is passed through the screw hole 311 and threadedly connected to the screw seat 413, limiting the upward movement of the heating component 4. This ensures that the upper surface of the heat-conducting frame 41 remains flush with the opening of the cavity 31 and is not exposed on the surface of the base 3, maintaining an aesthetic appearance and safe use. In addition, according to the different bottom shapes of the mixing bowl 1, by rotating the screw 415 to change its screwing depth in the screw seat 413, the upward movement position of the heating component 4 is changed, achieving different upward movement distances of the heating component 4 to meet the needs of mixing bowls 1 with different bottom shapes.

[0040] The limiting structure also includes an annular enclosure 414 extending downward along the outer edge of the heat-conducting frame 41. The lower surface of the heat-conducting frame 41, the annular enclosure 414, and the concave cavity 31 below it enclose a heating chamber 43, and the heating wire 42 is located in the heating chamber 43. The heating chamber 43 plays a necessary protective role for the heating wire 42, avoiding heat loss and safety risks such as electric shock and short circuit caused by the exposure of the heating wire 42. The annular enclosure 414 has an appropriate height. When the heating component 4 is not under the weight of the mixing bowl 1, the lower edge of the annular enclosure 414 does not contact the upper surface of the concave cavity 31 and there is a certain distance. As the heating component 4 moves downward under the weight of the mixing bowl 1, the lower edge of the annular enclosure 414 abuts the upper surface of the concave cavity 31, and the heating component 4 no longer moves downward, limiting the distance that the heat-conducting frame 41 can move downward relative to the concave cavity 31, ensuring the necessary space required for the heating wire 42 to operate normally in the heating chamber 43, and preventing the heating wire 42 from being squeezed or collided and damaged.

[0041] The limiting structure composed of the screw hole 311 and the screw seat 413 limits and adjusts the upward movement distance of the heating component 4 relative to the cavity 31, so that the upper surface of the heat-conducting frame 41 remains flush with the opening of the cavity 31 and is not exposed on the surface of the base 3, thereby maintaining the beautiful appearance and safe use of the food processor; another limiting structure composed of the annular enclosure 414 limits the downward movement distance of the heat-conducting frame 41 relative to the cavity 31, ensuring the necessary space required for the heating wire 42 to work normally in the heating chamber 43, and preventing the heating wire 42 from being squeezed or collided and damaged.

[0042] In this embodiment, a waterproof structure is provided between the heating element 4 and the cavity 31. This structure includes an annular weir 312 protruding from the upper surface of the cavity 31. The weir 312 is located within the heating chamber 43, and a drainage hole 313 is provided in the cavity 31 outside the heating chamber 43. When using the food processor, if water is spilled or overflows from the mixing bowl 1, it will flow along the outer wall of the mixing bowl 1, onto the base 3, and into the cavity 31. Since the heating element 4 is located within the cavity 31, if this water is not promptly drained and comes into contact with the heating element 4, it could damage the heating element 4 and potentially cause safety issues such as electrical leakage and short circuits. The drainage hole 313 in the cavity 31 allows water to drain. However, if a large amount of water enters the cavity 31 in a short period of time, the drainage hole 313 cannot quickly drain the water, resulting in water accumulation within the cavity 31. The annular weir 312 prevents this accumulated water from entering the heating chamber 43 and coming into contact with the heating wire 42. Because the projection of the heating wire 42 onto the upper surface of the cavity 31 lies within the annular cofferdam 312, the annular cofferdam 312 forms a waterproof structure surrounding the heating wire 42, further reducing the possibility of accumulated water coming into contact with the heating wire 42. The waterproof structure formed by the drainage hole 313 and the annular cofferdam 312 provides dual waterproofing for the heating element 4. When a small amount of water enters the cavity 31, it is drained through the drainage hole 313. When a large amount of water enters the cavity 31, the drainage hole 313 simultaneously drains the water while the annular cofferdam 312 prevents accumulated water in the cavity 31 from entering the heating chamber 43, thereby enhancing the waterproof protection of the heating element 4.

[0043] In this embodiment, the mixing bowl 1 has an integral bowl base 11 at its bottom. The outer wall of the bowl base 11 is provided with a plurality of positioning protrusions 111. The inner wall of the cavity 31 is provided with a plurality of positioning slots 314 corresponding to the positioning protrusions 111. Aligning and engaging the positioning protrusions 111 with the positioning slots 314 allows the mixing bowl 1 to be mounted on the base 3, securing the mixing bowl 1 in place during use. After mixing, the positioning protrusions 111 are unscrewed from the positioning slots 314 to remove the mixing bowl 1 from the base 3. To enhance the appearance, drainage holes 313 are provided on the upper surface of the cavity 31, below the positioning slots 314.

[0044] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
