Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a soymilk machine. Background Art

[0002] A traditional soymilk maker generally includes a machine head and a cup body. The machine head is buckled on the top of the cup body. The machine head includes an upper cover, a metal lower cover and a plastic lower cover located inside the metal lower cover. The metal lower cover and the upper cover form an installation cavity to install a motor and a control device. An anti-overflow electrode is provided on the plastic lower cover. Generally, the anti-overflow electrode is designed as an integral part of the plastic lower cover and then installed in the metal lower cover. A through hole is provided in the metal lower cover for the anti-overflow electrode to pass through and extend into the cup body. Generally, a silicone piece is required to be provided at the through hole for sealing.

[0003] This setting makes the assembly of the machine head complicated and the gaps in the silicone parts are not easy to clean. Moreover, in the high temperature environment of the cup body, long-term use will cause the plastic lower cover and silicone parts to deform, resulting in failure of the seal at the through hole, resulting in air and water leakage. Utility Model Content

[0004] The utility model provides a soymilk machine which optimizes the arrangement of the anti-overflow electrode, and not only completely solves the problem of sealing failure between the anti-overflow electrode and the metal lower cover in the prior art, but also solves the problem of complicated machine head installation and difficult cleaning caused by the installation of the anti-overflow electrode.

[0005] The technical solution adopted by the utility model is:

[0006] The utility model provides a soymilk machine, comprising a control device, a cup body, and a machine head, wherein the machine head is buckled on the top of the cup body, the machine head comprises a metal lower cover, the outer wall of the metal lower cover above the highest water level line of the cup body is integrally formed with a metal rod extending downward, the upper end of the metal rod is provided with an electrical connection part connected to the control device, and the lower end of the metal rod is provided with a detection part located in the cup body.

[0007] The soymilk machine provided by the utility model utilizes a metal lower cover to be integrally formed with a metal rod extending downward, the metal rod and the metal lower cover are integrally formed, and detection is performed using a detection portion of the metal rod. When the machine head is assembled, the sealing installation process between the detection piece for detection and the through hole of the metal lower cover required in the traditional technology is omitted, and the installation of the sealing ring is omitted, which can not only simplify the assembly process of the machine head component, but also completely prevent the occurrence of installation gaps and sealing failures between the metal rod and the metal lower cover, thereby preventing water from entering the machine head or leaking air. At the same time, when cleaning, the occurrence of installation gaps that cause residue accumulation and difficulty in cleaning is avoided, thereby facilitating the thorough cleaning of the outer surface of the metal lower cover, and the cleaning is convenient and clean. A detection part located in the cup body is provided at the lower end of the metal rod, and the slurry temperature or water level in the cup body is detected by the detection part. An electrical connection part connected to the control device is provided at the upper end of the metal rod to transmit the detected signal to the control device, thereby achieving precise control. The detection part is used to detect the temperature in the cup body, and the heating power or time of the soymilk maker is sensitively controlled to ensure that the soymilk is cooked and prevent the bottom from becoming sticky. The detection part is used to detect the water level in the cup body, for example, to perform overflow detection. When the slurry overflows and triggers the detection part, the control device receives a signal to control the heating tube to continue working or adjust the efficiency of the heating tube to avoid slurry overflow. The use is safe and reliable.

[0008] In a preferred embodiment, the outer surface of the metal lower cover is covered with an insulating layer, the detection part is higher than the highest water level line of the cup body, and the detection part is an anti-overflow detection part.

[0009] In a preferred embodiment, the outer surface of the metal lower cover is covered with an insulating layer, the detection part extends to the bottom of the cup body, and the detection part is an anti-dry burning detection part.

[0010] By coating the outer surface of the metal lower cover with an insulating layer and the detection part being higher than the highest water level line of the cup body, insulation between the anti-overflow detection part and the metal lower cover can be achieved, ensuring that the detection part and the grounding part of the soymilk maker (such as the knife shaft or the heating plate) are disconnected under normal conditions, and the two are connected only after the slurry boils and overflows to touch the detection part to realize the signal change, so that the control device obtains the anti-overflow signal.

[0011] By coating the outer surface of the metal lower cover with an insulating layer, the detection part extends to the bottom of the cup body, and the detection part is an anti-dry-burn detection part. The insulation between the anti-dry-burn detection part and the metal lower cover is achieved by the insulating layer. The anti-dry-burn detection part and the grounding part of the soymilk maker (such as the blade shaft or the heating plate) are connected through the liquid in the cup body under normal conditions. Only when the liquid becomes less and cannot touch the detection part, the two are disconnected, so that the control device obtains a dry-burn signal.

[0012] In a preferred embodiment, the insulating layer extends to wrap the outer circumference of the metal rod and the detection portion is exposed relative to the insulating layer.

[0013] Since the metal rod is extended downward from the part of the metal lower cover that is above the highest water level line of the cup body, a narrow horizontal space appears between the upper part of the metal rod and the metal lower cover. The horizontal distance between the metal rod and the metal lower cover in this part is small. In order to prevent the foam generated by the rotation of the slurry from staying in the horizontal space and causing the detection part to be falsely triggered, the insulating layer is extended to wrap around the outer circumferential surface of the metal rod and the detection part is exposed relative to the insulating layer. While ensuring that the detection part can sensitively detect the anti-overflow signal, false triggering of foam can be avoided, thereby achieving sensitive and accurate detection.

[0014] In a preferred embodiment, the electrical connection portion is located inside the metal lower cover and protrudes relative to the inner wall of the metal lower cover.

[0015] In a preferred embodiment, the control device is installed in the machine head, and a conductive sheet connected to the control device is fixed to the electrical connection portion.

[0016] By protruding the electrical connection part relative to the inner wall of the metal lower cover, it is convenient to connect the electrical connection part with the control device to ensure reliable transmission of the detection signal. By providing the conductive sheet, the connection area between the metal rod and the wiring harness can be expanded, which is conducive to the effective transmission of the detection signal and convenient for the connection of the line.

[0017] In a preferred embodiment, the insulating layer is an insulating coating coated on the outer surface of the metal lower cover or an insulating sleeve sleeved on the outer surface of the metal lower cover.

[0018] Whether the insulating layer is an insulating coating or an insulating sleeve mounted on the outer surface of the metal lower cover, the detection part and the metal lower cover can be insulated to prevent overflow or dry burning. The insulating layer is an insulating coating coated on the outer surface of the metal lower cover. The coating process is simple, and the insulating coating and the metal lower cover are integrated. On the basis of achieving insulation between the detection part and the metal lower cover for anti-overflow or anti-dry burning detection, the insulating coating can be a non-stick coating to prevent slurry adhesion, such as a ceramic coating, to facilitate cleaning of the machine head. Of course, the insulating sleeve can also be a plastic sleeve.

[0019] In a preferred embodiment, the interior of the metal rod is hollow, a temperature sensing element is installed in the detection portion, and the electrical connection portion is a lead wire connected to the temperature sensing element.

[0020] The interior of the metal rod is set to be hollow to provide installation space for a temperature sensing element, and the temperature sensing element is installed inside the detection part to achieve temperature detection. The lead connected to the temperature sensing element is connected to the control device as an electrical connection part, and the detected temperature signal is transmitted to the control device to control the heating power.

[0021] In a preferred embodiment, the detection portion extends to a position lower than the highest water level of the cup body, and the detection portion is a temperature detection portion for detecting the temperature of the liquid in the cup body;

[0022] Alternatively, the detection part is higher than the highest water level line of the cup body, and the detection part is a temperature detection part for detecting the air temperature in the cup body.

[0023] By extending the detection part to below the highest water level line of the cup body, the detection part can be extended into the slurry during the slurry preparation process, directly sensing the slurry temperature to achieve direct detection, and the detection reliability is higher. Moreover, the metal rod extending from top to bottom can also play a turbulent effect during the slurry crushing process, thereby improving the crushing efficiency.

[0024] By placing the detection part higher than the highest water level of the cup body, the detection part is a temperature detection part for detecting the air temperature in the cup body, so as to achieve indirect detection of the slurry temperature in the cup body and shorten the length of the metal rod.

[0025] In a preferred embodiment, the portion of the metal rod extending into the cup body is covered with an isolation sleeve, and the detection portion is exposed outside the isolation sleeve.

[0026] By arranging an isolation sleeve on the part of the metal rod extending into the cup body, the detection part is exposed from the isolation sleeve for detection, so as to prevent the temperature of the non-detection part and the detection part from being inconsistent due to uneven temperatures at different parts of the metal rod when the metal rod is long, resulting in inaccurate or abnormal detection.

[0039] Example 1

[0040] like Figure 1 As shown, this embodiment provides a soymilk maker, including a control device 30, a cup body 10, and a machine head 20. The machine head 20 is buckled on the top of the cup body 10. The machine head 20 includes a metal lower cover 21. The metal lower cover 21 has an outer wall above the highest water level of the cup body 10, and a downwardly extending metal rod 40 is integrally formed thereon. The upper end of the metal rod 40 is provided with an electrical connection portion 41 connected to the control device 30, and the lower end of the metal rod 40 is provided with a detection portion 42 located in the cup body 10.

[0041] Preferably, the head 20 includes an upper cover 22, which covers the metal lower cover 21 to enclose and form an installation cavity, and the motor 70 is fixedly installed in the installation cavity. Optionally, an external thread is provided at the lower part of the motor, and an internal thread connected to the external thread is provided on the inner surface of the metal lower cover 21, so that the motor is directly screwed in the metal lower cover 21. Of course, in fact, a plastic lower cover or a motor mounting seat can be provided in the installation cavity, and the motor is fixed in the installation cavity through the plastic lower cover or the motor mounting seat. The rotating shaft of the motor extends from the lower end surface of the metal lower cover 21 and is connected to the crushing knife 50 for crushing operation. A heating tube 80 is provided at the bottom of the cup body 10 to heat the liquid in the cup body 10 to prepare soy milk. An electrical coupling is provided between the head 20 and the cup body 10 to realize the electrical connection of the respective internal electrical components. Therefore, whether the control device 30 is installed in the head 20 or in the cup body 10, it can realize the electrical connection between the metal rod 40.

[0042] It should also be noted that the highest water level line can be selected as a scale line convexly arranged or printed on the side wall of the cup body 10.

[0043] In this embodiment, if Figure 1 As shown, the outer surface of the metal lower cover 21 is covered with an insulating layer 23, and the detection part 42 is higher than the highest water level line of the cup body 10, and the detection part 42 is an anti-overflow detection part.

[0044] The detection principle of the overflow prevention detection unit in this embodiment is as follows: Figure 1 As shown, one end of the rotating shaft on which the crushing blade 50 is mounted is used as a weakly conductive electrode connected to the ground wire. By coating the outer surface of the metal lower cover 21 with an insulating layer, the detection part 42 is set higher than the highest water level line of the cup body 10, so that insulation between the anti-overflow detection part and the metal lower cover 21 can be achieved. Under normal conditions, the detection part 42 and the weakly conductive electrode of the soymilk machine are disconnected. Only after the slurry boils and overflows to touch the detection part 42, the detection part 42 and the weakly conductive electrode are connected. The connection between the two realizes the change of the signal to form a strong electric signal, so that the control device 30 obtains the anti-overflow signal. Of course, in fact, the heating plate can also be used as a weakly conductive electrode connected to the ground wire, or a conductive electrode can be convexly provided on the heating plate alone.

[0045] The soymilk machine provided in the present embodiment utilizes the metal lower cover 21 to integrally form a metal rod 40 extending downward. The metal rod 40 and the metal lower cover 21 are integrally formed, and detection is performed using the detection portion 42 of the metal rod 40. When the machine head 20 is assembled, the sealing installation process between the detection member for detection and the through hole of the metal lower cover 21 required in the traditional technology is omitted, and the installation of the sealing ring is omitted, which can not only simplify the assembly process of the machine head 20 components, but also completely prevent the sealing failure between the metal rod 40 and the metal lower cover 21, thereby preventing the machine head 20 from water ingress or air leakage. At the same time, when cleaning, the installation gap that makes cleaning difficult is avoided, thereby facilitating the thorough cleaning of the outer surface of the metal lower cover 21, and making cleaning convenient and clean. A detection part 42 located in the cup body 10 is provided at the lower end of the metal rod 40. The slurry temperature or water level in the cup body 10 is detected by the detection part 42. An electrical connection part 41 connected to the control device 30 is provided at the upper end of the metal rod 40 to transmit the detected signal to the control device 30, thereby realizing precise control. The detection part 42 is used to detect the temperature in the cup body 10, and the heating power or time of the soymilk maker is sensitively controlled to ensure that the soymilk is cooked and prevent the bottom from becoming sticky. The detection part 42 is used to detect the water level in the cup body 10, for example, to perform overflow detection. When the slurry overflows and triggers the detection part 42, the control device 30 receives a signal to control the heating tube to continue working or adjust the efficiency of the heating tube to avoid slurry overflow. The use is safe and reliable.

[0046] like Figure 1 , Figure 2 As shown, the insulating layer 23 extends to wrap the outer circumference of the metal rod 40 and the detection portion 42 is exposed relative to the insulating layer 23 .

[0047] Since the metal rod 40 is extended downward from the portion of the metal lower cover 21 that is above the highest water level line of the cup body 10, a narrow horizontal space appears between the upper portion of the metal rod 40 and the metal lower cover 21. The horizontal distance between the metal rod 40 and the metal lower cover 21 at this portion is relatively small. In order to prevent the foam generated by the rotation of the slurry from staying in the horizontal space and causing the detection part 42 to be falsely triggered, the insulating layer is extended to wrap around the outer circumferential surface of the metal rod 40 and the detection part 42 is exposed relative to the insulating layer. This ensures that the detection part 42 can sensitively detect the anti-overflow signal while avoiding false triggering of foam, thereby achieving sensitive and accurate detection.

[0048] like Figure 1 , Figure 2 As shown, in this embodiment, the electrical connection portion 41 is located inside the metal lower cover 21 and protrudes relative to the inner wall of the metal lower cover 21. Figure 1 As shown, the control device 30 is installed at the bottom of the cup body 10, an electric coupler is provided between the head 20 and the cup body 10, and the electrical connection portion 41 is fixed with a conductive sheet 43 connected to the control device 30. Of course, in practice, the control device 30 can also be installed in the head 20 and directly connected to the conductive sheet.

[0049] By making the electrical connection part 41 protrude relative to the inner wall of the metal lower cover 21, it is convenient to connect the electrical connection part 41 with the control device 30 to ensure reliable transmission of the detection signal. By providing the conductive sheet 43, the connection area between the metal rod 40 and the wiring harness can be expanded, which is conducive to the effective transmission of the detection signal and convenient for the connection of the line.

[0050] It should be noted that in this embodiment, the insulating layer 23 is an insulating coating sprayed integrally on the outer surface of the metal lower cover 21, preferably a ceramic coating is used to achieve a non-stick effect. Of course, in practice, the insulating layer 23 can also be an insulating sleeve sleeved on the outer surface of the metal lower cover 21.

[0051] Whether the insulating layer 23 is an insulating coating or an insulating sleeve sleeved on the outer surface of the metal lower cover 21, the detection part 42 and the metal lower cover 21 can be insulated to prevent overflow or dry burning. The insulating layer 23 is an insulating coating coated on the outer surface of the metal lower cover 21. The coating process is simple, and the insulating coating and the metal lower cover 21 are integrated. On the basis of achieving insulation between the detection part 42 and the metal lower cover 21 to prevent overflow or dry burning, the insulating coating can be a non-stick coating to prevent slurry from adhering, so as to facilitate the cleaning of the machine head 20.

[0052] It should be noted that the metal rod 40 may be in the shape of a cylindrical shape with equal diameter, or in the shape of Figure 1 , 2 In another embodiment, as shown in FIG. Figure 3As shown, the outer diameter of the metal rod 40 increases first and then decreases from top to bottom, so as to reduce the probability of foam adhesion and prevent the occurrence of false overflow prevention.

[0053] More preferably, if Figure 1 As shown, the lower end of the metal lower cover 21 is integrally formed with a crushing cover 60 which is arranged outside the crushing blade 50, thereby improving the crushing efficiency. Compared with the method of installing the crushing cover 60 separately, it avoids slag accumulation in the gap between the crushing cover 60 and the metal lower cover 21, and realizes convenient cleaning of the machine head 20.

[0054] Example 2

[0055] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that a weakly conductive electrode 91 is protrudedly provided on the heating plate 90 alone.

[0056] In this embodiment, the outer surface of the metal lower cover 21 is covered with an insulating layer 23 , the detection portion 42 is higher than the highest water level of the cup body 10 , and the detection portion 42 is an anti-overflow detection portion.

[0057] The detection principle of the overflow prevention detection unit in this embodiment is as follows: Figure 1 As shown, the weak conductive electrode arranged on the heating plate is connected to the ground wire. By coating the outer surface of the metal lower cover 21 with an insulating layer, the detection part 42 is arranged above the highest water level line of the cup body 10, so that insulation between the anti-overflow detection part and the metal lower cover 21 can be achieved. Under normal conditions, the detection part 42 and the weak conductive electrode are disconnected. Only after the slurry boils and overflows to touch the detection part 42, the detection part 42 and the weak conductive electrode are connected. The connection between the two realizes the change of the signal to form a strong electric signal, so that the control device 30 obtains the anti-overflow signal.

[0058] Example 3

[0059] The difference between this embodiment and the first embodiment is that the detection part 42 extends to the bottom of the cup body 10 , the detection part 42 is an anti-dry-burning detection part, and the outer surface of the metal lower cover 21 is covered with an insulating layer.

[0060] The detection principle of the anti-dry-burning detection unit in this embodiment is: one end of the rotating shaft where the crushing knife 50 is installed (or the heating plate) is used as a weak conductivity electrode connected to the ground wire. By coating the outer surface of the metal lower cover 21 with an insulating layer, the detection unit 42 extends to the bottom of the cup body 10. For example, the bottom end of the detection unit is 3-10 mm away from the bottom wall of the cup body, so that the insulation between the anti-dry-burning detection unit and the metal lower cover 21 can be achieved. Under normal conditions, the detection unit 42 is connected to the weak conductivity electrode of the soymilk maker. Only when the liquid becomes less and cannot touch the detection unit 42, the two are disconnected, so that the control device 30 obtains a dry-burning signal to prevent the cup body 10 from dry-burning due to lack of water.

[0061] Example 4

[0062] The metal rod 40 is hollow inside, a temperature sensing element is installed in the detection part 42, and the electrical connection part 41 is a lead connected to the temperature sensing element. Preferably, the detection part 42 extends to below the highest water level of the cup body 10, and the detection part 42 is a temperature detection part 42 for detecting the temperature of the liquid in the cup body 10.

[0063] By setting the interior of the metal rod 40 to be hollow to provide installation space for the temperature sensing element, the temperature sensing element is installed inside the detection part 42 to achieve temperature detection. The lead connected to the temperature sensing element is connected to the control device 30 as the electrical connection part 41, and the detected temperature signal is transmitted to the control device 30 to control the heating power.

[0064] By extending the detection part 42 to below the highest water level of the cup body 10, the detection part 42 can be extended into the slurry during the slurry preparation process to directly sense the slurry temperature for direct detection, thereby achieving higher detection reliability. The metal rod 40 extending from top to bottom can also play a turbulent effect during the slurry crushing process, thereby improving the crushing efficiency.

[0065] Of course, in practice, the detection part 42 can also be higher than the highest water level line of the cup body 10. The detection part 42 is a temperature detection part 42 for detecting the air temperature in the cup body 10, thereby realizing indirect detection of the slurry temperature in the cup body 10 and shortening the length of the metal rod 40.

[0066] More preferably, the portion of the metal rod 40 extending into the cup body 10 is covered with an isolation sleeve, and the detection portion 42 is exposed outside the isolation sleeve.

[0067] By providing an isolation sleeve on the part of the metal rod 40 that extends into the cup body 10, which may be an insulating plastic sleeve, and selecting a thermal insulation material, the detection part 42 is exposed from the isolation sleeve for detection, so as to prevent the temperature of different parts of the metal rod 40 from being inconsistent with the temperature of the non-detection part and the detection part 42 due to uneven temperatures when the metal rod 40 is long, resulting in inaccurate or abnormal detection.

[0068] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0069] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0070] The above are only embodiments of the present invention and are not intended to limit the present invention.
