Abstract
Description
Technical Field
[0001] The utility model generally relates to the field of daily necessities, and more specifically to a food heater, which is especially used for thawing, heating or keeping warm infant food, such as breast milk, dairy products, complementary food ingredients, etc. Background Art
[0002] Infant foods such as breast milk used for infant feeding are usually stored in a refrigerated or frozen manner to extend their shelf life. When feeding, the above-mentioned infant foods need to be heated to a temperature and state suitable for feeding first. Water bath heating is a commonly used food heating method. However, existing water bath heating food heaters for infant foods have problems such as uneven temperature, local overheating, and long heating time during the heating process. For example, when the heating part of the food heater is located at the bottom of the accommodating cavity for accommodating the food to be heated, due to the characteristics of water thermal expansion and contraction, hot water is easy to float, so the temperature of the upper water bath is too high and the water temperature at different positions is uneven. For infant foods, especially breast milk, insufficient heating may cause indigestion in infants, and local overheating caused by local overheating of the water bath is easy to cause food deterioration or nutrient loss, which is not desirable.

[0037] Figure 1 Schematic diagram of a food heater 1 according to some embodiments of the present invention is shown. Figure 1 As shown, the food heater 1 includes a main body 2, in which a receiving cavity 3 is formed for placing water for a water bath and food to be heated. The main body 2 may also be formed with an operation panel 4 located on the outside, which may be connected to a controller (not shown) in the food heater 1 to control parameters such as heating temperature and heating time. The food heater 1 may also include a basket 5 that is detachably placed in the receiving cavity 3 to facilitate taking and placing food. The basket 5 may include a partition plate 6 to divide the basket 5 into a plurality of holding portions so as to respectively hold containers containing food therein.
[0038] Figure 2 Shows Figure 1 A partial cross-sectional view of a food heater 1 is shown in FIG. Figure 2 The carrycot 5 has been removed. Figure 2 As shown, the food heater 1 may include a heating portion 10 to heat the accommodating cavity 3. The heating portion 10 may be as follows: Figure 2 As shown, the heating unit 10 is disposed below the accommodating chamber 3. It should be understood that in other embodiments not shown, the heating unit 10 may also be disposed at other positions, such as the side of the accommodating chamber 3. Figure 4It is clearly shown that the heating part 10 may include a substantially plate-shaped heating disk 11, and the heating disk 11 may be configured to close the bottom of the accommodating cavity 3. It should be understood that in other embodiments not shown, the accommodating cavity 3 of the main body 2 may have an integrally formed side wall and bottom wall, and the heating part 10 may be disposed below the bottom wall. Other components of the heating part 10 (e.g., a heating coil connected to the heating disk 11, etc.) may be constructed and disposed in a known manner, which will not be described in detail herein.
[0039] like Figure 2 As shown, the food heater 1 further comprises a rotor assembly 20, which is configured to stir the water in the accommodating chamber 3 by rotating the rotor, so as to make the water temperature more uniform and increase the heating speed.
[0040] Combine the following Figure 3 and Figure 4 The rotor assembly 20 is described in detail. Figure 3 and Figure 4 As shown, the rotor assembly 20 may include a first rotor 21 and a second rotor 22. The first rotor 21 may be disposed inside the accommodating chamber 3. The second rotor 22 may be disposed outside the accommodating chamber 3 and connected to a driving portion 7, such as a motor, that drives the second rotor 22, so that the second rotor 22 may be driven by the driving portion 7 to rotate around the rotation axis X. Figure 4 As shown, the first rotor 21 may be spaced apart from the second rotor 22 by the heating plate 11 .
[0041] The first rotor 21 and the second rotor 22 can be configured to interact with each other through magnetic attraction, so that the rotation of the second rotor 22 around the rotation axis X can drive the first rotor 21 to rotate around the rotation axis X. Therefore, the first rotor 21 can be driven to rotate by driving the second rotor 22 to rotate by the driving unit 7, and then the water in the accommodating chamber 3 can be stirred by the rotation of the first rotor 21 to achieve the purpose of making the water temperature uniform and increasing the heating speed. In addition, when the second rotor 22 is arranged outside the accommodating chamber 3, since the first rotor 21 and the second rotor 22 interact with each other through magnetic attraction, the first rotor 21 and the second rotor 22 or the driving unit 7 are not in direct contact, which facilitates the sealing of the accommodating chamber 3.
[0042] like Figure 3As shown, the first rotor 21 and the second rotor 22 may be respectively embedded with a plurality of first magnets 32 and a plurality of second magnets 33 distributed around the rotation axis X. For example, the plurality of first magnets 32 may be three first magnets 32 evenly distributed around the rotation axis X, and the plurality of second magnets 33 may be three second magnets 33 evenly distributed around the rotation axis X. Advantageously, the first magnet 32 is sealedly embedded in the interior of the first rotor 21 to avoid being corroded by water in the accommodating chamber 3. For example, the first magnet 32 may be sealedly embedded in the interior of the first rotor 21 by sealingly connecting the cover plate 34 to the first rotor 21. The cover plate 34 may be connected to the first rotor 21, for example, by ultrasonic welding.
[0043] like Figure 3 and Figure 4 As shown, the rotor assembly 20 may include a first rotor seat 23, which may be configured to support the first rotor 21 in a manner that allows the first rotor 21 to rotate freely. Figure 4 As shown, the first rotor seat 23 may include a pin-shaped portion 24 extending along the rotation axis X, and the first rotor 21 may include a hole portion 25 configured to receive the pin-shaped portion 24, so as to achieve the cooperation between the first rotor seat 23 and the first rotor 21. It should be understood that in other embodiments not shown, it is also feasible that the pin-shaped portion 24 is provided on the first rotor 21, and the hole portion 25 is provided on the first rotor seat 23.
[0044] like Figure 4 As shown, for example, the first rotor 21 and the first rotor seat 23 may be configured to contact each other only on a plane perpendicular to the rotation axis X and a circumferential surface around the rotation axis X. By minimizing the number of contact surfaces and / or the size of the contact area between the first rotor 21 and the first rotor seat 23, the rotation resistance of the first rotor 21 may be reduced, thereby reducing wear and noise. Figure 4 In the illustrated embodiment, the aforementioned one plane is the end plane 26 of the pin-shaped portion 24, and the aforementioned one circumferential surface is the outer circumferential surface 27 of the pin-shaped portion 24. It should be understood that in other embodiments not shown, the first rotor 21 and the first rotor seat 23 may also have a greater number of contact surfaces and / or a larger contact area. It should be understood that in other embodiments not shown, the first rotor 21 and the first rotor seat 23 may also contact each other via another contact surface alternatively or additionally.
[0045] like Figure 4As shown, the rotor assembly 20 may include a rotor seat buffer 28, which may be embedded in the first rotor seat 23 and protrude from a side of the first rotor seat 23 facing the heating unit 10, and contact the component (e.g., the heating plate 11) on which the first rotor seat 23 is placed. Thus, during the rotation of the first rotor 21, the friction and impact between the first rotor seat 23 and the component placed thereon are alleviated, thereby reducing wear and noise.
[0046] like Figure 4 As shown, the driving part 7 can be installed to the main body 2 through the driving part bracket 8, and a driving part bracket buffer 9 can be arranged between the main body 2 and the driving part bracket 8 to alleviate the noise and vibration generated by the operation of the driving part 7.
[0047] For example, the driving unit 7 can drive the second rotor 22 at a speed of 1500 rpm to 3500 rpm, so that the first rotor 21 can stir the water in the accommodating chamber 3 more stably and fully. Advantageously, the outer diameter of the first rotor 21 can be set to 3 cm to 5 cm, which helps to achieve stable rotation at the above speed of the driving unit 7 and helps to achieve the first rotor 21 to stir the water in the accommodating chamber 3 fully. Figure 3 As shown, the outer periphery of the first rotor 21 may be provided with a plurality of blades 31 distributed along the circumferential direction of the first rotor 21, so as to facilitate sufficient stirring of the water in the accommodating chamber 3 during the rotation of the first rotor 21. For example, the first rotor 21 may include six blades 31 evenly distributed along the circumferential direction. Figure 4 As shown, one or more material removal portions 35 may be formed in the first rotor 21 to reduce the weight of the first rotor 21. Similarly, one or more material removal portions 36 may also be formed in the second rotor 22.
[0048] The food heater 1 according to the utility model can stir the water in the accommodating chamber 3 through the rotor assembly 20, thereby avoiding or alleviating the problems of uneven water bath temperature, local overheating, long heating time, etc. in the accommodating chamber 3. In addition, the food heater 1 according to the utility model also has the advantages of simple structure, durability and low noise.
[0049] The utility model has been described through the above-mentioned embodiments, but it should be understood that the above-mentioned embodiments are only for the purpose of example and description, and are not intended to limit the present disclosure to the scope of the described embodiments. It should be understood by those skilled in the art that more variations and modifications can be made according to the teachings of the present disclosure, and these variations and modifications all fall within the protection scope of the present disclosure. It should be noted that the features or feature combinations according to the present disclosure described above and the features and feature combinations mentioned in the drawings and / or only shown in the drawings can be used not only in the corresponding given combinations, but also in other combinations or alone, without departing from the scope of the present disclosure.
