Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a soymilk maker. Background Art

[0002] A soymilk maker usually includes a machine head and a cup body, and components such as a motor and a circuit board are installed inside the machine head. Therefore, the sealing inside the machine head is required to be good to ensure that the motor, circuit board and other components will not be damaged and fail due to water entering the machine head.

[0003] In order to achieve a good seal of the machine head, the prior art CN201821606067.X discloses a soymilk machine head, which includes an upper cover, a transition piece made of plastic, and a metal lower cover. A seal is provided between the upper cover and the transition piece, and a sealing ring is provided between the metal lower cover and the transition piece. A fourth stud protrudes downward on the inner fixed surface of the upper cover, and a fourth assembly hole is provided on the transition piece and the metal lower cover. The fourth screw passes through the fourth assembly hole and the seal and is tightened on the fourth stud to assemble the upper cover, the seal, the transition piece, the sealing ring and the metal lower cover together. Through the above structure, the soymilk machine head manufactured has good sealing performance, isolates the installation chamber from the outside world, prevents external water from flowing into the installation chamber, and better provides waterproof protection for the electronic components in the head.

[0004] However, in the above structure, the upper cover, the transition piece and the metal lower cover are fixed together at the same time by the fourth screw. During the operation of the soymilk maker, the heat generated by the motor and the heat transferred by the steam through the metal lower cover will be transferred to the plastic transition piece and the upper cover. The deformation of the upper cover will cause the transition piece to deform, or the transition piece itself will expand and contract due to heat, resulting in the connection between the transition piece and the upper cover and the metal lower cover being affected, causing the seal between the upper cover, the transition piece and the metal lower cover to fail, allowing water to enter the machine head, resulting in damage to electronic components such as the motor and circuit boards. Utility Model Content

[0005] The present application provides a soymilk maker that can effectively solve the technical problem of sealing failure between the upper cover, the transition bracket and the metal lower cover caused by thermal expansion and contraction deformation of the transition bracket.

[0006] The present application provides a soymilk maker, including a machine head, which includes an upper cover, a transition bracket and a metal lower cover arranged in sequence along its axial direction, the upper cover and the metal lower cover clamp the transition bracket and the three are fixedly connected, a first seal is provided between the upper cover and the transition bracket, and a second seal is provided between the transition bracket and the metal lower cover, the transition bracket includes an annular body, an annular support portion extending laterally outward from the top of the annular body, an annular side portion extending downward from the support portion, and an annular flange arranged at the lower end of the side portion and extending laterally outward, an annular cavity with a bottom opening is formed between the side portion and the outer wall of the annular body, so that the side portion forms a cantilever structure relative to the support portion, the second seal is clamped between the flange and the metal lower cover, the upper cover presses the first seal on the support portion, and the upper cover and the metal lower cover clamp the flange and are fixedly connected to the flange.

[0007] In the above-mentioned structure of the present application, the side of the transition bracket forms a cantilever structure relative to the supporting part, and the upper cover and the metal lower cover clamp the flange and are fixedly connected to the flange. When the heat generated during the operation of the soymilk maker is transferred to the transition bracket and the upper cover, and since an annular cavity with a bottom opening is formed between the side and the outer wall of the annular body, the side has a certain elasticity and deformation space. Then, when the upper cover or the transition bracket expands and contracts due to thermal expansion and contraction, resulting in an uneven flange or stress concentration at the connection position between the flange and the upper cover and the metal lower cover, the formed cantilever structure can offset and compensate for the deformation of the flange caused by thermal expansion and contraction, reduce the stress concentration at the flange, so as to avoid the flange from breaking, and also avoid the seal between the transition bracket and the metal lower cover from being affected, so that the seal between the transition bracket and the metal lower cover will not fail.

[0008] Moreover, since an annular cavity with a bottom opening is formed between the side and the outer wall of the annular body, the air in the annular cavity can block the noise generated during the operation of the soymilk maker motor and cutter, thereby improving the noise reduction effect of the soymilk maker.

[0009] As a preferred technical solution, an annular sealing groove is provided on the top of the support portion, the first sealing member is embedded in the sealing groove, and an annular rib is provided on the upper cover, and the rib presses the first sealing member into the sealing groove.

[0010] By pressing the first sealing member tightly against the sealing groove through the convex rib, a good sealing effect between the upper cover and the transition bracket can be effectively ensured, and the installation of the first sealing member is firm and stable.

[0011] As an optimal technical solution, a plurality of positioning grooves are provided on the flange, and a plurality of positioning posts are provided on the upper cover for inserting into the positioning grooves. The upper cover is positioned on the flange through the cooperation between the positioning posts and the positioning grooves, and fasteners are fixed to the positioning posts from the bottom of the metal lower cover through the metal lower cover, the second sealing member and the positioning grooves in sequence, so that the upper cover, the transition bracket and the metal lower cover are fixedly connected.

[0012] By setting a positioning groove on the flange and a positioning column on the upper cover, and inserting the positioning column into the positioning groove, the installation and positioning between the upper cover and the transition bracket can be quickly achieved. Then, fasteners are used to achieve a fixed connection between the upper cover, the transition bracket and the metal lower cover, making assembly more convenient and quick.

[0013] As a preferred technical solution, the positioning groove is provided with a drain outlet, and the drain outlet extends to the edge of the flange.

[0014] Through the drain port, condensed water that may be formed inside the machine head due to the cooling of steam can flow into the positioning groove and be discharged through the drain port to between the transition bracket and the upper cover, and then flow out through the gap between the two, without flowing into the inside of the transition bracket, and thus will not affect the motor, circuit board and other electronic components inside the machine head.

[0015] As a preferred technical solution, the cross-sectional area of ​​the annular cavity gradually increases from top to bottom.

[0016] That is, by setting the annular cavity to have a large bottom opening and a cavity structure that gradually tapers from bottom to top, when the noise generated by the motor is transmitted to the annular cavity, the noise will enter the annular cavity through the bottom opening and be absorbed and reflected multiple times by the inner wall of the annular cavity, thereby greatly reducing the noise that is finally transmitted and further improving the noise reduction effect.

[0017] As an optimal technical solution, the soymilk maker also includes a motor, a motor mounting seat and a bearing seat located in the metal lower cover, the motor is mounted on the motor mounting seat, the bearing seat is fixed to the bottom of the metal lower cover, the motor mounting seat is fixedly connected to the bearing seat through a fixing member, and a shock-absorbing member is provided on the outside of the fixing member to isolate the fixing member from the motor mounting seat or the bearing seat.

[0018] By setting up a shock-absorbing part to isolate the fixing part from the motor mounting seat or the bearing seat, a soft connection contact is formed between the motor mounting seat and the bearing seat, that is, the two are no longer rigidly connected, so that the vibration will not be transmitted to the metal lower cover during the operation of the motor, thereby avoiding the formation of resonance, thereby reducing the generation of noise and improving the noise reduction effect.

[0019] As a preferred technical solution, the motor mounting seat is provided with a connecting hole, and the shock absorber includes a first shock absorber portion, a second shock absorber portion and a third shock absorber portion connected in sequence, the first shock absorber portion is located between the end portion of the fixing member and the motor mounting seat to isolate the end portion of the fixing member and the motor mounting seat, the second shock absorber portion is located in the connecting hole and is sleeved on the outside of the fixing member to isolate the peripheral wall of the fixing member from the motor mounting seat, and the third shock absorber portion extends out of the connecting hole and abuts against the end face of the bearing seat to isolate the bearing seat and the motor mounting seat.

[0020] That is, by setting a first shock-absorbing part to isolate the end of the fixing member and the motor mounting seat, setting a second shock-absorbing part to isolate the surrounding wall of the fixing member and the motor mounting seat, and setting a third shock-absorbing part to isolate the bearing seat and the motor mounting seat, a contactless connection between the motor mounting seat and the bearing seat is achieved.

[0021] As a preferred technical solution, there are multiple connecting holes, and there are multiple corresponding shock absorbing members, which are arranged in a one-to-one correspondence with the connecting holes;

[0022] Alternatively, the connecting hole is provided with a plurality of holes, the shock absorbing member includes a shock absorbing body, the first shock absorbing portion is provided with a plurality of parts and is integrally formed on the shock absorbing body, and the plurality of first shock absorbing parts are provided in a one-to-one correspondence with the connecting holes.

[0023] As a preferred technical solution, the motor body is threadedly connected to the motor mounting seat, and a gap is formed between the outer wall of the motor mounting seat and the inner wall of the metal lower cover, so that the motor mounting seat floats relative to the metal lower cover.

[0024] When the motor is running, the motor will cause the motor mount to float slightly, and a gap will be formed between the motor mount and the inner wall of the metal lower cover. The metal lower cover will not be affected by the floating, and will not produce large vibrations or noise.

[0025] As a preferred technical solution, the transition bracket is provided with a ring-shaped extension portion extending downward along the inner wall of the metal lower cover, the motor is fixed in the inner space of the extension portion, and the lower portion of the extension portion forms the motor mounting seat.

[0048] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0050] In the prior art, taking the soymilk maker disclosed in CN201821606067.X as an example, the upper cover, seal, transition piece, sealing ring and metal lower cover of the machine head are directly assembled together by screws. This structure has the problem of sealing failure due to thermal expansion and contraction deformation of the transition piece.

[0051] In order to solve the above problems, the present invention provides a soymilk machine. Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the soymilk maker provided in this embodiment. The soymilk maker in this embodiment includes a head 1, a cup assembly 2, and a base 3. The cup assembly 2 is used to hold ingredients and is placed on the base 3. The head 1 is partially placed inside the cup assembly 2 to process the ingredients. A control panel and control buttons can be provided on the base 3 to control the entire soymilk maker.

[0052] Figure 2 This is a schematic diagram of the exploded structure of the machine head 1 provided in this embodiment. Figure 3 The nose 1 provided for this embodiment shows a cross-sectional view of the annular cavity 125. Figure 2 and Figure 3 As shown, the machine head 1 of this embodiment includes an upper cover 11, a transition bracket 12, a metal lower cover 13, a motor 14 and a cutter 15, wherein the upper cover 11, the transition bracket 12 and the metal lower cover 13 are arranged in sequence along the axial direction of the machine head 1, and the three are fixedly connected. A first seal 16 is provided between the upper cover 11 and the transition bracket 12, and a second seal 17 is provided between the transition bracket 12 and the metal lower cover 13. Through the first seal 16 and the second seal 17, the sealing between the upper cover 11 and the transition bracket 12, and between the transition bracket 12 and the metal lower cover 13 can be effectively achieved. The above-mentioned motor 14 and cutter 15 can be placed in the metal lower cover 13, and the motor 14 can drive the cutter 15 to rotate to process the food in the cup body assembly 2. It can be understood that a spoiler 18 can also be installed at the bottom of the metal lower cover 13 of this embodiment to improve the processing effect.

[0053] Please refer to Figure 4-Figure 6 ,in Figure 4 is a schematic diagram of the three-dimensional structure of the transition bracket 12 of this embodiment, Figure 5 The transition bracket 12 of this embodiment shows a three-dimensional cross-sectional view of the annular cavity 125. Figure 6The figure is a cross-sectional view of the transition bracket 12 of this embodiment. In this embodiment, the transition bracket 12 includes an annular body 121, a support portion 122, a side portion 123, and a flange 124. The annular body 121 is an annular frame structure. The support portion 122 is formed by extending laterally outward from the top of the annular body 121. The side portion 123 is annular and extends downward from the support portion 122. The flange 124 is provided at the lower end of the side portion 123 and extends laterally outward. Through the above structure, the transition bracket 12 is connected to the upper cover 11 and the metal lower cover 13 through the flange 124. That is, the second seal 17 is clamped between the flange 124 and the metal lower cover 13. The upper cover 11 and the metal lower cover 13 clamp the flange 124. Subsequently, screws are used to secure the upper cover 11, the flange 124, the second seal 17, and the metal lower cover 13.

[0054] In this embodiment, an annular cavity 125 with a bottom opening is formed between the side portion 123 and the outer wall of the annular body 121, so that the side portion 123 forms a cantilever structure relative to the support portion 122. Through this cantilever structure, when heat generated during operation of the soymilk maker is transferred to the transition bracket 12 and the upper cover 11, the formation of the annular cavity 125 with a bottom opening between the side portion 123 and the outer wall of the annular body 121 provides the side portion 123 with a certain degree of elasticity and deformation space. Furthermore, when the upper cover 11 or the transition bracket 12 expands or contracts due to heat, causing the flange 124 to become uneven, or when stress is concentrated at the connection between the flange 124, the upper cover 11, and the metal lower cover 13, the formed cantilever structure can offset and compensate for the deformation of the flange 124 caused by thermal expansion and contraction, reducing the stress concentration at the flange 124 to prevent the flange 124 from breaking. It also prevents the seal between the transition bracket 12 and the metal lower cover 13 from being affected, thereby preventing the seal between the transition bracket 12 and the metal lower cover 13 from failing. The problem of sealing failure caused by thermal expansion and contraction deformation of the transition bracket 12 in the prior art is effectively solved, and the service life of the transition bracket 12 is effectively improved.

[0055] In addition, the cantilever structure allows the side portion 123 to provide a certain degree of elasticity when the flange 124, the upper cover 11 and the metal lower cover 13 are fixedly connected by screws, thereby facilitating the positioning of the screws and the mounting holes on the flange 124, thereby making the assembly of the flange 124 and the screws smoother.

[0056] It should be noted that an annular cavity 125 with a bottom opening is formed between the side portion 123 and the outer wall of the annular body 121. The air in the annular cavity 125 can block and absorb the noise generated during the operation of the soymilk maker motor 14 and the cutter 15, thereby effectively improving the noise reduction effect of the soymilk maker.

[0057] In this embodiment, Figure 6As shown, the cross-sectional area of ​​the annular cavity 125 gradually increases from top to bottom. In other words, the annular cavity 125 is configured as a cavity structure with a large bottom opening and a gradually decreasing diameter from bottom to top. When the generated noise is transmitted to the annular cavity 125, the noise enters the annular cavity 125 through the bottom opening and is absorbed and reflected multiple times by the inner wall of the annular cavity 125. This can greatly reduce the noise that is ultimately transmitted, further improving the noise reduction effect.

[0058] Figure 7 For this embodiment Figure 3 As shown in the enlarged schematic diagram at point A, in this embodiment, an annular sealing groove 1221 is provided at the top of the support portion 122, into which the first sealing member 16 is inserted. Correspondingly, an annular rib 111 is provided on the upper cover 11, which presses the first sealing member 16 into the sealing groove 1221. This structure effectively ensures a good seal between the upper cover 11 and the transition bracket 12, and ensures a secure and stable installation of the first sealing member 16. Furthermore, the provision of the sealing groove 1221 facilitates the installation and positioning of the rib 111, thereby facilitating the installation and positioning of the upper cover 11 and the transition bracket 12.

[0059] In this embodiment, preferably Figure 4 As shown, multiple positioning grooves 1241 can be provided on the flange 124. The multiple positioning grooves 1241 are preferably provided along the circumference of the flange 124. In other words, the flange 124 has a structure with a certain thickness to enable the opening of the positioning grooves 1241. Correspondingly, multiple positioning posts 112 are provided on the upper cover 11. Each positioning post 112 can be inserted into a positioning groove 1241. The arrangement of the positioning posts 112 and the positioning grooves 1241 can conveniently achieve the positioning of the upper cover 11 installed on the flange 124. After the positioning posts 112 are inserted into the positioning grooves 1241, fasteners (such as screws) are inserted from the bottom of the metal lower cover 13 through the metal lower cover 13, the second sealing member 17, and the positioning grooves 1241 in sequence to secure the metal lower cover 13 to the positioning posts 112, thereby firmly connecting the upper cover 11, the transition bracket 12, and the metal lower cover 13. Preferably, the fastener is a screw and is threadedly connected to the positioning column 112. The threaded connection between the fastener and the positioning column 112 can clamp and fix the second sealing member 17 between the metal lower cover 13 and the flange 124 to achieve a good sealing effect.

[0060] More preferably, in this embodiment, a drain port 1242 is provided at the positioning groove 1241, and the drain port 1242 extends to the edge of the flange 124. When condensed water appears on the transition bracket 12, the condensed water can flow into the positioning groove 1241, and then be discharged through the drain port 1242 to between the transition bracket 12 and the upper cover 11, and then flow out of the machine head 1 through the gap between the transition bracket 12 and the upper cover 11. Therefore, the condensed water will not flow into the inside of the transition bracket 12, and will not affect the motor 14 and circuit board and other electronic components inside the machine head 1, thereby effectively protecting the motor 14 and circuit board and other electronic components.

[0061] It should be noted that in this embodiment, a plurality of positioning portions 1243 may be provided at the bottom of the flange 124, and corresponding positioning holes 131 are provided on the top of the metal lower cover 13 to match the positioning portions 1243. When the metal lower cover 13 is assembled with the flange 124, the positioning portions 1243 are inserted into the positioning holes 131 to achieve rapid positioning between the flange 124 and the top of the metal lower cover 13, providing a basis for the subsequent fixed connection between the upper cover 11, the transition bracket 12, and the metal lower cover 13, and improving assembly efficiency. Preferably, the positioning portion 1243 can be provided below the corresponding positioning groove 1241. In this case, the positioning connection between the positioning column 112 of the upper cover 11 and the positioning groove 1241, and the positioning connection between the positioning portion 1243 and the positioning hole 131 are all located in one place, and are located at the connection between the upper cover 11, the transition bracket 12, and the metal lower cover 13, making the connection between the three more precise and stable.

[0062] like Figure 5 As shown, an annular support plate 1211 extends from the inner wall of the lower end of the annular body 121 toward its center. The upper cover 11 includes a top wall 113 and a peripheral wall 114 connected to the top wall 113 ( Figure 3 As shown in FIG, the top wall 113 is provided with a downwardly protruding shape, and an annular groove is formed between the lower surface of the top wall 113 and the peripheral wall 114, and the annular cavity 125 is located in the groove. In addition, the top wall 113 of the upper cover 11 can also be supported on the above-mentioned support plate 1211 to further support the upper cover 11.

[0063] Figure 8 For this embodiment Figure 3 The enlarged schematic diagram of point B is as follows: Figure 8 As shown, a coupler mounting cavity is formed between the upper cover 11 and the transition bracket 12, and the coupler 19 is installed in this coupler mounting cavity. Specifically, a coupler mounting hole 1231 can be defined in the side portion 123, and one end of the coupler 19 is sealingly inserted through the coupler mounting hole 1231. It will be understood that a seal can be achieved between the coupler 19 and the side portion 123 via a sealing ring 191. The provision of the coupler 19 enables communication between the motor 14 in the machine head 1 and the control board on the machine base 3, thereby enabling control of the motor 14.

[0064] Considering the prior art, noise reduction treatment is often required for the handpiece. This is primarily because the handpiece typically houses a motor, a motor mounting block for the motor, and a bearing block for the motor's output shaft. This bearing block is then fixedly connected to the metal lower cover. The motor generates vibrations during operation, and the motor mounting block and bearing block are typically connected using screws. This vibration is then transmitted to the metal lower cover, which, when resonated, generates significant noise.

[0065] Based on the above problems, Figure 9 and Figure 10 As shown, Figure 9 This is a schematic diagram of the explosion structure of the machine head 1 of this embodiment showing the shock absorber 13'. Figure 10 This is a cross-sectional view of the machine head 1 of this embodiment, showing the shock absorber 13'. The soymilk maker of this embodiment also includes a motor 14, a motor mounting base 11', a bearing base 12', and a shock absorber 13', all of which are disposed within the metal lower cover 13. The motor 14 is mounted on the motor mounting base 11', and the bearing base 12' is fixed to the bottom of the metal lower cover 13. The motor mounting base 11' is fixedly connected to the bearing base 12' via a fixing member, and a shock absorber 13' is disposed on the outer side of the fixing member to isolate the fixing member from the motor mounting base 11' or the bearing base 12'.

[0066] That is to say, by providing a shock-absorbing member 13' that can isolate the fixing member from the motor mounting seat 11' or the fixing member from the bearing seat 12', a soft connection contact is formed between the motor mounting seat 11' and the bearing seat 12', that is, the two are no longer rigidly connected. When the motor 14 is running, the vibration of the motor 14 is transmitted to the motor mounting seat 11'. At this time, the vibration of the motor mounting seat 11' will be absorbed by the shock-absorbing member 13', and the shock-absorbing member 13' isolates the bearing seat 12' from the motor mounting seat 11', thereby avoiding or reducing the vibration transmitted from the motor mounting seat 11' to the bearing seat 12', and then the vibration will not be transmitted to the metal lower cover 13, thereby avoiding resonance of the metal lower cover 13, reducing the generation of noise, and achieving a better noise reduction effect.

[0067] Figure 11 For this embodiment Figure 10 The enlarged schematic diagram of point C is as follows: Figure 11-14 As shown, a connecting hole 111' is provided on the motor mounting seat 11', and the shock absorbing member 13' is installed in the connecting hole 111' of the motor mounting seat 11', and isolates the motor mounting seat 11' from the bearing seat 12'. Specifically, in an practicable technical solution, as Figure 12-14As shown, the shock absorber 13' of this embodiment includes a first shock absorber portion 131', a second shock absorber portion 132' and a third shock absorber portion 133' connected in sequence, wherein the first shock absorber portion 131' is located between the end of the fixing member and the motor mounting seat 11' to isolate the end of the fixing member from the motor mounting seat 11', the second shock absorber portion 132' is located in the connecting hole 111' and is sleeved on the outside of the fixing member to isolate the peripheral wall of the fixing member from the motor mounting seat 11', and the third shock absorber portion 133' extends out of the connecting hole 111' and abuts against the end face of the bearing seat 12' to isolate the bearing seat 12' from the motor mounting seat 11'. That is to say, by providing the first shock-absorbing portion 131', the second shock-absorbing portion 132' and the third shock-absorbing portion 133', the motor mounting seat 11' and the bearing seat 12' can be completely isolated, thereby achieving a contactless connection between the motor mounting seat 11' and the bearing seat 12', thereby preventing the vibration generated during the operation of the motor 14 from being transmitted to the metal lower cover 13.

[0068] exist Figure 12-14 In the illustrated embodiment, the motor mount 11' is provided with multiple connection holes 111', which are arranged circumferentially on the motor mount 11'. Correspondingly, multiple shock absorbers 13' are also provided, with each shock absorber 13' being installed in a corresponding connection hole 111'. The arrangement of multiple shock absorbers 13' can achieve a more uniform vibration reduction effect between the motor mount 11' and the bearing seat 12'.

[0069] Of course, it is understandable that in another solution, Figure 15-17 As shown, the shock absorber 13' of this embodiment may further include a shock absorber body 134'. The first shock absorbing portion 131' is integrally formed with the shock absorber body 134', and the multiple first shock absorbing portions 131' correspond one-to-one with the multiple connection holes 111'. In other words, in this embodiment, the shock absorber body 134' integrates multiple first shock absorbing portions 131' and can be placed between the motor mounting base 11' and the bearing base 12', further improving the shock absorption and noise reduction effects.

[0070] In this embodiment, it should be noted that the shock absorber 13' can be installed not only in the connection hole 111' of the motor mounting base 11', but also on the bearing base 12'. In this case, the shock absorber 13' can be installed by providing a connection hole on the bearing base 12'. This embodiment does not specifically limit this.

[0071] Please refer to Figure 10In this embodiment, the motor 14 is threadedly connected to the motor mount 11', and a gap is formed between the outer wall of the motor mount 11' and the inner wall of the metal lower cover 13, allowing the motor mount 11' to float relative to the metal lower cover 13. When the motor 14 is running, the motor 14 causes the motor mount 11' to float slightly. Due to the gap formed between the motor mount 11' and the inner wall of the metal lower cover 13, the metal lower cover 13 is not affected by the floating movement. At this time, combined with the shock-absorbing effect of the shock-absorbing member 13', no significant vibration is generated, and thus no significant noise is generated.

[0072] In this embodiment, the transition bracket 12 may optionally include an annular extension extending downwardly along the inner wall of the metal lower cover 13. The motor 14 is secured within the interior space of the extension, with the lower portion of the extension forming the motor mounting seat 11'. In other words, the motor mounting seat 11' is integrally formed with the transition bracket 12, facilitating the manufacture of the motor mounting seat 11' and its assembly with other components.

[0073] In other embodiments, the bottom end of the extension portion formed by the downward extension of the above-mentioned transition bracket 12 may not form a motor mounting seat 11', but may be directly connected to the motor mounting seat 11' or the spoiler 18 of the metal lower cover 13. In this case, the motor 14 is located in the internal space of the extension portion.

[0074] The soymilk maker of this embodiment can solve the technical problem of sealing failure between the upper cover 11, the transition piece and the metal lower cover 13 caused by thermal expansion and contraction deformation of the transition bracket 12, and can also improve the noise reduction effect.
