Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a milk frother and a coffee machine. Background Art

[0002] As people's living standards improve, more and more people like to drink coffee. Adding milk foam to some coffee will improve the taste.

[0003] Many coffee machines are equipped with a milk frothing device for frothing milk. Existing milk frothing machines usually wind a thin steel wire around a ring to form multiple metal rings, and use the rotation of the metal rings to stir and cut the milk. Existing milk frothing machines have technical problems such as uneven stirring and difficulty in cleaning. Utility Model Content

[0004] The present application provides a milk frother and a coffee machine, which can solve the technical problems of uneven stirring and difficulty in cleaning of the milk frother in the prior art.

[0005] The present application provides a milk frother, which includes:

[0006] A runner, the runner comprising a body and a blade assembly; the blade assembly is accommodated in the body;

[0007] A screen is detachably connected to the rotating wheel, and the screen is located above the blade assembly;

[0008] Along the height direction of the rotating wheel, the rotating wheel has a flow guide portion higher than the screen, and the flow guide portion has a set height.

[0009] In the milk frother provided by the present application, the rotating wheel and the screen form a detachable connection, so that the milk frother is easier to clean. The screen is located above the blade assembly, and the rotating wheel is provided with a guide portion higher than the screen. More milk enters the inside of the rotating wheel through the guide portion and the screen. The rotation of the blade assembly stirs the milk at a high frequency, so that the milk frother can froth the milk more evenly and delicately.

[0010] As a possible implementation manner, the height of the guide portion is 1 / 4 to 1 / 3 of the overall height of the main body.

[0011] In the above scheme, the height of the guide part cannot be too high. If it is too high, the overall height of the runner needs to be increased accordingly. If the overall height of the runner is not increased, there will be insufficient space between the screen and the impeller assembly, affecting the stirring and whipping effect. The height of the guide part cannot be too low either. Too low a height will affect the diversion effect. More milk passes through the guide part into the runner to better improve the stirring effect and make the stirring more uniform. By setting the height of the guide part to 1 / 4 to 1 / 3 of the overall height of the runner, a better drainage effect can be achieved while ensuring the overall installation space of the runner.

[0012] As a possible implementation manner, the height of the guide portion is no more than 10 mm.

[0013] The above solution can achieve the best flow diversion effect without increasing the overall height of the runner.

[0014] As a possible implementation manner, a flow guiding slope inclined toward the screen is provided on the top of the flow guiding portion.

[0015] In the above scheme, the guide slope guides the milk to flow into between the guide part and the screen, and then passes through the screen and is stirred by the blade assembly.

[0016] As a possible implementation, the blade assembly includes a fixing portion and a circumferential blade connected to the fixing portion;

[0017] The milk foam machine further comprises a connecting rod and a main unit, wherein the connecting rod connects the fixing portion and the main unit.

[0018] In the above solution, the blades are arranged on the periphery of the fixing part and rotate along with the rotation of the fixing part, thereby stirring the milk in the milk cup.

[0019] As a possible implementation method, a limiting portion is provided on the inner wall of the body;

[0020] The screen is provided with a clamping portion, and the limiting portion is clamped and matched with the clamping portion, so that the rotating wheel and the screen are detachably connected.

[0021] In the above scheme, the detachable connection between the rotating wheel and the screen is achieved by the clamping cooperation between the limiting part and the clamping part. The limiting part can be directly formed on the inner wall of the body, and the clamping part can be directly formed on the screen. This structure and process implementation are simpler.

[0022] As a possible implementation, the screen includes a mesh body and an extension portion connected to the mesh body;

[0023] The clamping portion is a flange arranged on the extending portion;

[0024] The limiting portion is a groove formed on the inner wall of the body; the flange is snap-fitted with the groove.

[0025] In the above solution, the structure and process of the flange are relatively simple, and the groove can be formed on the inner wall of the body by mechanical processing, and the structure and process are also relatively simple.

[0026] As a possible implementation manner, a notch is provided on the extension portion.

[0027] In the above scheme, the notch divides the extension part into multiple independent parts, so that the extension part has a certain elastic deformation space when the screen and the rotating wheel are assembled. During assembly, the extension part is pressed to extend a part of the screen into the rotating wheel, and the clamping part and the limiting part are engaged, so that the screen and the rotating wheel can be installed. During disassembly, the extension part is pressed to disengage the clamping part from the limiting part, and the screen is pulled out of the rotating wheel, so that the screen and the rotating wheel can be cleaned separately. The entire disassembly and assembly process is simple and easy to operate.

[0028] As a possible implementation manner, a plurality of stirring blades are arranged on the outer wall of the body, and each stirring blade extends along the height direction of the rotating wheel.

[0029] In the above scheme, by arranging stirring blades on the outer wall of the main body, the stirring amplitude can be increased to make the milk foam richer.

[0030] The present application also provides a coffee machine, comprising a main body, wherein the coffee machine further comprises a milk frother as described in any one of the above items, and the milk frother is installed on the main body.

[0031] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0063] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0064] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0065] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0066] Figure 1 A schematic diagram of the structure of a milk frother provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the embodiment of the present application provides a milk frothing machine, and the milk frothing machine 100 may include a main unit 30, and the main unit 30 is used as a power output source to provide power for stirring liquid. The milk frothing machine 100 may also include a sheath 50, which is connected to the main unit 30 and contains a stirring device of the milk frothing machine 100. When the milk frothing machine 100 is not needed, the sheath 50 can protect and isolate the stirring device.

[0067] Figure 2 This is a schematic diagram of the structure of the milk frother provided in the embodiment of the present application after the sheath is removed, as shown in FIG. Figure 2 As shown, the milk frother 100 includes a rotating wheel 10 and a screen 20. The rotating wheel 10 is used to stir milk to generate foam when rotating. The milk foam can form smooth and delicate micro-foam after flowing through the screen 20, thereby improving the taste of coffee. The rotating wheel 10 can be connected to the host 30 through a connecting rod 40. The host 30 drives the connecting rod 40 to rotate, thereby driving the rotating wheel 10 to rotate, which will be described in detail below.

[0068] Figure 3 This is a schematic diagram of an exploded view of a milk frother provided in an embodiment of the present application, as shown in FIG. Figure 3 In the illustrated embodiment, the screen 20 is installed above the rotating wheel 10 and is detachably connected to the rotating wheel 10 .

[0069] Figure 4 for Figure 3 An enlarged view of a part of the structure, such as Figure 4 As shown, the rotating wheel 10 includes a body 11 and a blade assembly 12, and the blade assembly 12 is accommodated in the body 11. The screen 20 is detachably connected to the rotating wheel 10, and the screen 20 is located above the blade assembly 12. The blade assembly 12 rotates to generate high-frequency stirring for the milk in the milk cup, and the milk flows through the screen 20 and is cut into fine milk foam. Since the screen 20 is detachably connected to the rotating wheel 10, it is more convenient to clean.

[0070] Figure 5 This is a cross-sectional view of the impeller and screen after installation. Figure 5 As shown, along the height direction of the runner 10 (the X direction in the figure is the radial direction, and the Z direction is the height direction), the runner 10 has a guide portion 11 a higher than the screen 20, and the guide portion 11 a has a set height H.

[0071] Reference Figure 5 It can be seen that the height of the guide portion 11a is the height of the wheel 10 above the top of the screen 20. The setting of the guide portion 11a can play a drainage role. More milk enters the interior of the wheel 10 through the guide portion 11a and the screen 20. The blade assembly 12 rotates to stir the milk at a high frequency, so that the milk frother 100 can whip the milk more evenly and delicately.

[0072] In a specific embodiment, the height H of the guide portion 11a is 1 / 4 to 1 / 3 of the overall height of the body 11 of the runner 10. The height of the guide portion 11a cannot be too high. If it is too high, the overall height of the runner 10 needs to be increased accordingly. If the overall height of the runner 10 is not increased, insufficient space will result between the screen 20 and the impeller assembly 12, affecting the stirring and whipping effect. The height of the guide portion 11a cannot be too low either. Too low a height will affect the diversion effect. More milk passes through the guide portion 11a and enters the interior of the runner 10, which can better improve the stirring effect and make the stirring more uniform. By setting the height of the guide portion 11a to 1 / 4 to 1 / 3 of the overall height of the runner 10, a better drainage effect can be achieved while ensuring the overall installation space of the runner 10.

[0073] Specifically, in this embodiment, the height of the guide portion 11 a is no greater than 10 mm, so that the guide portion 11 a can achieve the best guide effect without increasing the overall height of the runner 10 .

[0074] Reference Figure 5 As shown, the top of the guide portion 11a is provided with a guide slope 11b inclined toward the screen 20. The guide slope 11b may be a chamfer formed by mechanical processing. When the milk frother 100 is working, the blade assembly 12 stirs the milk. During the stirring process, the guide slope 11b guides the milk to flow between the guide portion 11a and the screen 20, and then passes through the screen 20 and is repeatedly stirred by the blade assembly 12.

[0075] like Figure 4 As shown, in a specific embodiment, the blade assembly 12 includes a fixing portion 121 and a circumferential blade 122 connected to the fixing portion 121. The blade 122 has an inclined surface to guide the milk to flow up and down. Figure 3 The milk frother further includes a connecting rod 40 and a main unit 30 , wherein the connecting rod 40 connects the fixing portion 121 and the main unit 30 .

[0076] In this embodiment, the fixing portion 121 may be a sleeve-shaped structure with a mounting hole in the middle, and the connecting rod 40 is inserted into the mounting hole of the fixing portion 121 to achieve the connection between the connecting rod 40 and the runner 10. The blades 122 are distributed on the periphery of the fixing portion 121. The number of blades 122 may be multiple, and in this embodiment, there are three. Each blade 122 has an inclined surface so that the milk can move up and down when stirring the milk. The blades 122 may be formed on the periphery of the fixing portion 121 by an integrated molding process, or may be connected to the fixing portion 121 by welding or other processes. The fixing portion 121 is located at the center of the runner 10, and the connecting rod 40 rotates to drive the runner 10 to rotate, and no eccentricity occurs, so that the stirring is more uniform.

[0077] Figure 6 for Figure 5 In the enlarged view at A in FIG. 1 , in a specific embodiment, as Figure 4 and Figure 6 As shown, the inner wall 111 of the body 11 is provided with a limiting portion 112, and the screen 20 is provided with a clamping portion 22a, and the limiting portion 112 is clamped and matched with the clamping portion 22a, so that the rotating wheel 10 and the screen 20 are detachably connected.

[0078] When the screen 20 needs to be disassembled, the clamping portion 22 a is disengaged from the limiting portion 112 , so that the screen 20 and the rotating wheel 10 can be disassembled.

[0079] As an optional method, the screen 20 can be an integrally formed plastic part with screen holes formed thereon. The screen 20 can also be formed by combining a mesh part and a plastic part.

[0080] In a specific embodiment, the screen 20 includes a mesh body 21 and an extension portion 22 connected to the mesh body 21, wherein the extension portion 22 is formed in a cylindrical shape, and a clamping groove is provided on the inner wall, and the edge of the mesh body 21 is clamped in the clamping groove to achieve the installation and fixation of the mesh body 21 and the extension portion 22. Specifically, the clamping portion 22a can be a flange provided on the extension portion 22, and the flange is formed by integral molding, and the structure and process are relatively simple.

[0081] The limiting portion 112 is a groove formed on the inner wall 111 of the body 11 . The groove can be formed by machining, and the flange is snap-fitted with the groove to achieve a detachable connection between the screen 20 and the wheel 10 .

[0082] Continue to refer to Figure 4 , a notch 22b is provided on the extension part 22. The notch 22b divides the extension part 22 into a plurality of independent parts, so that the extension part 22 has a certain elastic deformation space when the screen 20 is assembled with the runner 10. During assembly, the extension part 22 is pressed to extend a part of the screen 20 into the runner 10, and the clamping part 22a is engaged with the limiting part 112, so that the screen 20 and the runner 10 can be installed. During disassembly, the extension part 22 is pressed to disengage the clamping part 22a from the limiting part 112, and the screen 20 is pulled out of the runner 10, so that the screen 20 and the runner 10 can be cleaned separately, and the entire disassembly and assembly process is simple and easy to operate.

[0083] Figure 7 This is a schematic diagram of an angle after the rotor and screen are installed. Figure 7 As shown, in a specific embodiment, a plurality of stirring blades 113 are provided on the outer wall of the body 11, and each stirring blade 113 extends along the height direction of the rotating wheel 10. The stirring blade 113 can have various shapes, which can be a straight long strip or a strip with an arc, which is not further limited here. By providing the stirring blade 113 on the outer wall of the body 11, the stirring amplitude can be increased, making the milk foam richer.

[0084] The body 11 of the rotating wheel 10 may not be provided with the stirring blade 113. Figure 8 The figure shows a schematic diagram of the structure of another type of rotating wheel.

[0085] The embodiment of the present application also provides a coffee machine, including a main body, wherein the coffee machine also includes a milk frother 100 provided in any embodiment of the present application, and the milk frother is installed in the main body. When it is necessary to make milk froth, the milk frother 100 can be removed from the main body to make milk froth, and after the milk froth is made, the milk frother 100 is cleaned and then installed in the main body.

[0086] In the milk frother and coffee machine provided in the embodiment of the present application, the rotating wheel and the screen form a detachable connection, so that the milk frother is easier to clean. The screen is located above the blade assembly, and the rotating wheel is provided with a guide portion higher than the screen. More milk enters the inside of the rotating wheel through the guide portion and the screen. The rotation of the blade assembly stirs the milk at a high frequency, so that the milk frother can froth the milk more evenly and delicately.

[0087] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
