Description

Technical Field

[0001] The utility model relates to an electric kitchen appliance, in particular to a soybean milk machine. Background Art

[0002] In order to solve the problem of the head heating tube or the cup body being burnt, the existing soymilk maker is equipped with a heating tube in the head. For example, patent No. CN201120495041.4 discloses a soymilk maker, in which a heating part is arranged at the bottom of the head lower cover, and the heating part includes a containing shell and a heating element located in the containing shell. On the one hand, the heating element is not in direct contact with the liquid to avoid the food from being burnt. On the other hand, the heat generated by the heating tube can be quickly transferred out through the head lower cover by heating the head, and the motor shaft drives the crushing knife to rotate, so as to diffuse and transfer the heat outward, thereby producing a better cooking effect. However, since a heating tube is arranged in the machine head, the heating tube needs to be provided with a terminal to be electrically connected to the control board through a wire, and since a motor is arranged above the heating tube, the motor and the lower cover of the machine head are coaxially arranged, and the terminal of the heating tube is often arranged in the gap between the motor and the lower cover of the machine head. Since the gap between the motor and the lower cover of the machine head is small, the terminal is easy to come into contact with the motor, and the vibration and heat generated when the motor is working will be transmitted to the terminal. Over time, the terminal of the heating tube will be damaged. In severe cases, it will affect the connection between the control board and the heating tube, causing the soymilk maker to fail to work normally.

[0003] In addition, patent number CN201220384953.9 discloses a soymilk maker, which, in order to increase the capacity of the storage component, offsets the motor assembly in the lower cover of the machine head and the cup body, thereby forming a larger space on the side of the cup body away from the motor for placing a storage component with a larger capacity. However, the heating method of the soymilk maker is not described in detail. Regardless of the heating method used, the aforementioned problems still exist. Utility Model Content

[0004] The utility model provides a soymilk machine, the purpose of which is to reasonably arrange the installation of the motor assembly in the machine head so that the wiring terminal of the heating tube has a larger installation space to avoid the risk of leakage caused by the contact between the wiring terminal and the motor. At the same time, the larger installation space makes the wiring operation of the wiring terminal more convenient, and the connection and routing of the wiring harness are also safer.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a soymilk maker, including a machine head, the machine head including a machine head lower cover, a motor assembly and a heating tube located below the motor assembly are arranged in the machine head lower cover, and the characteristic is that: the motor assembly is arranged offset from the center line of the machine head lower cover, and an escape space is formed between the inner wall of the machine head lower cover on the side away from the motor assembly and the motor assembly, and a vertical terminal is arranged at the end of the heating tube, and the terminal extends upward into the escape space.

[0006] Furthermore, the motor assembly includes a motor, the motor includes a motor body, the heating tube is located below the motor body, the motor body is set away from the center line of the lower cover of the machine head, and the avoidance space is located between the motor body and the inner wall of the lower cover of the machine head away from the motor body.

[0007] Furthermore, a heat insulation plate is provided between the motor body and the heating tube to isolate the two.

[0008] Furthermore, the heat insulation board is provided with a through hole for the wiring terminal to pass through, and the wiring terminal passes through the through hole and extends upward into the avoidance space.

[0009] Furthermore, the heating tube includes a heating body located below the motor body, the heating body is connected to the terminal, the heating body is covered by a heat insulation board, there is a gap between the heat insulation board and the inner wall of the lower cover of the machine head, and the terminal extends upward through the gap into the avoidance space.

[0010] Furthermore, the heat insulation board is fixedly connected to the lower cover of the machine head; or, the motor body presses the heat insulation board onto the heating tube; or, a motor bracket for fixing the motor body is provided under the motor body, and the motor body presses the heat insulation board onto the heating tube through the motor bracket.

[0011] Furthermore, the motor assembly includes a motor and a motor cover arranged outside the motor, the motor cover is arranged to deviate from the center line of the lower cover of the machine head, and the avoidance space is located between the motor cover and the inner wall of the lower cover of the machine head away from the motor cover.

[0012] Furthermore, a motor bracket for fixing the motor assembly is provided under the motor assembly, the motor bracket having a bottom surface, the bottom surface of the motor bracket being recessed upward to form a receiving groove, the heating tube being located in the receiving groove, and the bottom surface of the motor bracket outside the receiving groove being pressed against the inner surface of the bottom wall of the lower cover of the machine head.

[0013] Furthermore, the machine head includes a control board, an edge of the control board is provided with a wire hook, a wiring terminal is connected to a wire, and the wire passes upward through the wire hook through the avoidance space and is electrically connected to the control board.

[0014] Furthermore, the machine head includes an upper cover on the machine head, and the control board is fixedly connected to the bottom of the upper cover on the machine head; or, an annular bracket is provided on the lower cover of the machine head, and the control board is provided on the annular bracket, and the wires pass through the annular bracket and the wire harness hook in sequence upward through the avoidance space and are electrically connected to the control board.

[0015] After adopting the above technical solution, the following beneficial technical effects are achieved:

[0016] 1. In the utility model, the motor assembly and the lower cover of the machine head are offset to form an avoidance space on one side of the lower cover of the machine head away from the motor assembly, and the heating tube is provided with a vertical terminal, which extends upward into the avoidance space. Since the motor assembly is offset to one side of the lower cover of the machine head, the space for accommodating the terminal in the lower cover of the machine head is larger than when the motor and the lower cover of the machine head are coaxially arranged. When the motor assembly is working, the distance between the motor assembly and the terminal increases, thereby avoiding the risk of leakage caused by the interference between the motor assembly and the terminal. At the same time, the avoidance space can increase the installation space of the terminal, making the connection operation between the wire and the terminal more convenient. The larger space can also avoid direct contact between the wire and the motor assembly, prevent the wire from being damaged by heat due to contact with the motor assembly, and improve the routing safety of the wire. In addition, the terminal is vertically arranged, so that the wire connected to the terminal can be directly connected to the control board upward to avoid bending and damage of the wire.

[0017] 2. Since the motor body is offset relative to the lower cover of the machine head, the blade connected to the motor shaft is not in the center of the cup body. After the motor works, it drives the blade to rotate, so that the slurry in the area where the blade is located and the slurry on the side of the cup body away from the blade produce flow velocity changes, forming a turbulent effect; the heating tube is set inside the machine head. When the soymilk machine starts working, the heat is transferred to the slurry in the cup body through the heating tube in the machine head. The heating tube and the slurry are not in direct contact to avoid burning of the food. On the other hand, the heat generated by the heating tube can be quickly transferred out through the lower cover of the machine head through the heating of the machine head. Combined with the rotation of the crushing knife driven by the motor shaft, the heat is diffused and transferred outward, resulting in a better cooking effect;

[0018] 3. A horizontal heat insulation board is set on the lower cover of the machine head. The heat insulation board separates the motor and the heating tube into different spaces, blocking the heat emitted by the heating tube when working and preventing the motor from overheating. At the same time, a through hole is set on the heating board so that the wiring terminal of the heating tube can pass through the through hole and extend into the avoidance space;

[0019] 4. A motor bracket is arranged below the motor assembly, and a receiving groove for receiving the heating tube is arranged at the bottom of the motor bracket. The bottom of the receiving groove abuts against the bottom inner wall of the lower cover of the machine head, so that the bottom of the motor bracket avoids contact with the heating tube, and at the same time, it is convenient to install the motor above the heating tube;

[0020] 5. By setting a wire harness hook at the edge of the control board, the wires connected to the terminal of the heating tube pass upward through the avoidance space through the wire harness hook and are electrically connected to the control board, so that the wires are gathered in the wire harness hook to avoid the wires being scattered in the lower cover of the machine head.

[0026] Figure 1 The utility model discloses a structure in which a motor assembly and a lower cover of a machine head are offset. A soymilk maker comprises a machine head, wherein the machine head comprises a lower cover 1, wherein a motor assembly and a heating tube 4 located below the motor assembly are arranged inside the lower cover 1, and the motor assembly is arranged offset from the center line of the lower cover 1. The motor assembly comprises a motor, and the motor comprises a motor body 2. The motor body 2 is arranged offset from the center line of the lower cover 1 of the machine head. Since the motor body 2 is offset relative to the lower cover of the machine head, an avoidance space 8 is formed between the side wall of the lower cover 1 of the machine head away from the motor body 2 and the motor body 2. A vertical terminal 3 is arranged at the end of the heating tube 4 located below the motor body 2. The terminal 3 is located below the avoidance space, and the terminal 3 extends upward into the avoidance space 8.

[0027] like Figure 2 As shown, a horizontal heat insulation board 9 can be arranged between the motor body 2 and the heating tube 4. The heat insulation board 9 is located between the motor body 2 and the heating tube 4 to isolate the heating tube 4 from transferring heat to the motor when working. The heat insulation board 9 can be a closed board that divides the lower cover of the machine head into two spaces, upper and lower. At this time, the heat insulation board located between the motor body 2 and the inner wall of the lower cover 1 of the machine head away from the motor body 2 is at the bottom of the avoidance space. The terminal 3 of the heating tube 4 located below the avoidance space 8 needs to pass through the heat insulation board and extend into the avoidance space. Therefore, a through hole for the terminal 3 to pass through is arranged at a position of the heat insulation board 9 close to the terminal 3, and the terminal 3 extends upward into the avoidance space 8 through the through hole; the heating tube 4 includes a heating body and a terminal connected to the heating body. When the heating body is located below the motor body, the heat insulation board 9 needs to cover the heating body below the motor body 2. The end of the heating tube is located below the avoidance space. There is a gap between the heat insulation board 9 and the inner wall of the lower cover of the machine head away from the motor body. The terminal vertically arranged at the end of the heating tube passes through the gap upward and extends into the avoidance space.

[0028] By setting a horizontal insulation board between the motor body and the heating tube 4, the insulation board separates the motor body and the heating tube 4 into different spaces, which can isolate the heat generated by the heating tube 4 when it is working, avoiding excessive temperature rise of the motor and affecting the normal operation of the motor.

[0029] like Figure 3 As shown, the motor assembly may include a motor and a motor cover 10 arranged on the outside of the motor, and the motor cover 10 and the lower cover of the machine head are offset. At this time, the avoidance space 8 is located between the motor cover 10 and the inner wall of the lower cover 1 of the machine head away from the motor cover; the motor cover 10 may be a structure with an opening at the upper end, and the motor is loaded into the motor cover from the upper end opening, and the bottom wall of the motor cover separates the motor from the heating plate. Since the motor cover 10 is arranged on the outside of the motor, the motor is also isolated from the heating tube 4, and the heat transfer from the heating tube 4 to the motor can also be blocked, thereby playing a role of heat insulation. Of course, as mentioned above, when a heat insulation plate 9 is arranged under the motor body, the motor cover can also be arranged on the outside of the motor body. At this time, the motor cover can be a structure with an opening at the lower end, and the motor cover is arranged on the outside of the motor body from top to bottom.

[0030] The utility model does not impose any restriction on the fixing of the heat insulation board 9. The heat insulation board 9 can be fixedly connected to the lower cover 1 of the machine head, and the motor body 1 is arranged on the heat insulation board 9. Of course, a motor bracket can also be arranged below the motor body 2, and the motor body and the motor bracket are fixedly connected, and the motor bracket is fixed on the heat insulation board 9. The heat insulation board can also be fixed by the cooperation of the motor and the heating tube 4, and the heat insulation board 9 can be pressed onto the heating tube 4 through the motor body. Alternatively, a motor bracket can be arranged below the motor body, and the motor body and the motor bracket are fixedly connected, and the motor body presses the heat insulation board 9 onto the heating tube through the motor bracket.

[0031] The motor cover 10 arranged on the outside of the motor can be fixedly connected to the lower cover 1 of the machine head, the upper end of the motor cover 10 is open, and the motor is installed in the motor cover 10 from top to bottom; the bottom wall of the motor cover 10 can also be pressed against the heating tube 4 by the motor. For the same reason, a motor bracket can be arranged under the motor, and the motor is fixedly connected to the motor bracket, and the motor presses the bottom wall of the motor cover 10 against the heating tube 4 through the motor bracket; similarly, as mentioned above, when a heat insulation board is arranged under the motor body, the motor cover can be a structure with an open lower end, and the motor cover is arranged on the outside of the motor body from top to bottom, and the bottom of the motor cover is fixed on the heat insulation board.

[0032] The heating tube 4 can be integrally formed at the bottom of the machine head lower cover 1. In this case, a motor bracket can be arranged under the motor assembly, the motor assembly is fixedly connected to the motor bracket, the motor bracket is tightly pressed against the bottom wall of the machine head lower cover 1, and the motor bracket can also be fixedly connected to the bottom wall of the machine head lower cover. In this case, the heating tube 4 can be integrally formed at the bottom side wall of the machine head lower cover 1 to avoid affecting the connection between the bottom of the motor bracket and the bottom wall of the machine head lower cover; the heating tube can also be integrally formed at the bottom wall of the machine head lower cover, and the area where the heating tube is located is smaller than the area of ​​the bottom wall of the machine head lower cover. In this case, Figure 4As shown, the bottom surface of the motor bracket 13 is recessed upward to form a receiving groove 14, the area where the heating tube is located is located in the receiving groove, and the bottom surface of the motor bracket outside the receiving groove is located outside the area where the heating tube is located, and abuts against the inner surface of the bottom wall of the lower cover of the machine head; the heating tube 4 can also be an annular heating tube welded to the bottom of the lower cover 1 of the machine head, and the annular heating tube is arranged around the bottom of the lower cover 1 of the machine head. At this time, the bottom of the motor bracket fixedly connected to the motor assembly needs to avoid the annular heating tube. Therefore, when the annular heating tube is arranged close to the side wall of the lower cover 1 of the machine head, the bottom of the motor bracket can be located on the inner side of the area surrounded by the annular heating tube, and is fixedly connected to the bottom wall of the lower cover of the machine head; when the area surrounded by the annular heating tube is smaller than the area of ​​the bottom wall of the lower cover of the machine head, at this time, the bottom surface of the motor bracket is recessed upward to form a receiving groove, the annular heating tube is located in the receiving groove, and the bottom surface of the motor bracket outside the receiving groove is located outside the area where the annular heating tube is located, and abuts against the inner surface of the bottom wall of the lower cover of the machine head.

[0033] By arranging a motor bracket under the motor assembly, the motor bracket is directly pressed against the bottom of the machine head lower cover 1, so that the installation of the motor assembly is more convenient. At the same time, the bottom surface of the motor bracket is recessed upward to form a receiving groove, and the heating tube is located in the receiving groove. The bottom surface of the motor bracket outside the receiving groove is pressed against the inner surface of the bottom wall of the machine head lower cover, making the installation of the motor bracket safer.

[0034] The terminal 3 of the heating tube 4 needs to be electrically connected to the control board 12 through the wire 11, and the installation position of the control board 12 is not limited. For example, the head of the soymilk machine also includes a head cover 7, and the control board 12 is fixed to the bottom of the head cover 7. At this time, the wire 11 connected to the terminal 3 of the heating tube 4 passes upward through the avoidance space 8 and enters the head cover 7. In order to facilitate the fixation of the wire 11, a wire harness hook can be set on one side edge of the control board 12, and the wire 11 can pass through the wire harness hook to be electrically connected to the control board 12; in addition, a ring bracket for placing the control board 12 can be set on the head lower cover 1, and the control board 12 is placed on the ring bracket. At this time, the wire 11 connected to the terminal 3 of the heating tube 4 passes upward through the avoidance space and the wire harness hook in turn, and then is electrically connected to the control board.

[0035] By setting a wire harness hook on the control board 12, the wire 11 connected to the terminal 3 can be limited so that the wire 11 can be gathered in the wire harness hook, avoiding the wire 11 from being distributed in a disorderly manner in the lower cover of the machine head.

[0036] The motor body 2 and the lower cover 1 of the machine head are offset so that an escape space is formed in the lower cover 1 of the machine head. The escape space can accommodate the terminal 3 of the heating tube 4. At this time, there is a relatively large gap between the terminal 3 and the motor body. When the motor is working, the motor is prevented from contacting the terminal 3, and the risk of leakage caused by the interference between the motor component and the terminal is avoided. The larger space also makes the wiring operation of the terminal more convenient, and can also avoid direct contact between the wire and the motor component, preventing the wire from contacting the motor component and being damaged by heat; at the same time, since the terminal 3 is vertically arranged, the wire 11 connected to the terminal 3 can be directly connected to the control board 12 upward from the terminal 3, avoiding a large bend of the wire 11 In addition, since the motor is offset relative to the lower cover 1 of the machine head, the blade 6 connected to the motor shaft 5 is not in the center of the cup body. After the motor works, it drives the blade 6 to rotate, so that the slurry in the area where the blade 6 is located and the slurry on the side of the cup body away from the blade 6 produce flow velocity changes, forming a turbulent effect; the heating tube is set inside the machine head. When the soymilk machine starts working, heat is transferred to the slurry in the cup body through the heating tube in the machine head. The heating tube is not in direct contact with the slurry to avoid burning of the ingredients. On the other hand, the heat generated by the heating tube can be quickly transferred out through the lower cover of the machine head by heating the machine head, and the motor shaft drives the crushing knife to rotate, so as to diffuse and transfer the heat outward, thereby producing a better cooking effect.

[0037] In addition, in order to improve the crushing effect, existing soymilk machines usually have spoiler ribs on the side walls of the cup body. When the soymilk machine is working, the spoiler ribs on the side walls of the cup body will disturb the slurry in the cup body that is driven by the crushing knife to rotate, causing the material to move irregularly, increasing the chance of the material contacting the crushing knife and improving the crushing effect. In the present technical solution, since the motor is offset relative to the lower cover 1 of the machine head, when the machine head cover is set on the cup body, the motor is also in an offset state relative to the cup body. When the soymilk maker is working, the motor drives the blade to rotate. Since the motor is offset relative to the cup body, in the cup body area on the side where the motor is located, the high-speed rotation of the blade produces a faster slurry flow rate, while on the side of the cup body away from the motor, the slurry flow rate is lower. As a result, two spaces with different flow rates are formed in the cup body. During the rotation of the slurry, the material and water form an internal circulation, which has a self-turbulence effect. Of course, in order to better enhance the turbulence effect, spoiler ribs can also be provided on the side wall of the cup body. However, since the motor is in an offset position relative to the cup body, the slurry in the cup body area where the motor is located produces a certain self-turbulence effect. Therefore, the number of spoiler ribs on the side wall of the cup body in the area where the motor is located can be reduced.

[0038] Of course, in order to increase the self-perturbing effect of the soymilk maker, while the motor and the lower cover of the machine head are offset, the lower cover of the machine head can also be offset relative to the cup body. At this time, two spaces are formed between the lower cover of the machine head and the inner wall of the cup body. On the offset side of the lower cover of the machine head, the distance between the lower cover of the machine head and the side wall of the cup body is shorter, and the distance between the lower cover of the machine head and the inner wall of the cup body away from the lower cover of the machine head is larger. Thus, two spaces of different sizes are formed in the cup body. When the soymilk maker is working, the rotation of the blade drives the slurry to switch back and forth between the two spaces continuously, thereby enhancing the effect of self-perturbing flow.
