Description

Technical Field

[0001] The utility model relates to the field of kitchen household appliances, and particularly relates to a food processor. Background Art

[0002] There is a type of existing food processor including a main machine and a mixing cup assembly installed on the main machine. The mixing cup can be taken and placed on and off the main machine. The mixing cup is provided with an upper coupler, and the main machine is provided with a lower coupler. When the mixing cup is placed in place on the main machine, the upper coupler and the lower coupler are coupled and electrically connected, so that the mixing cup can work normally.

[0003] Specifically, for one type with a motor disposed inside the main machine, a positioning ring for installing the cup body assembly is provided at the top of the main machine. The inner side of the positioning ring is provided with a lower connector and a lower coupler. When a motor with a relatively small volume is adopted, the main machine can be set to be thinner and the overall height is lower. When a user wipes the outer surface of the main machine or the cup body assembly and water drops down, it is easy to flow to the vicinity of the lower coupler and may flow into the main machine through the installation gap of the lower coupler, resulting in damage to the electronic devices inside the main machine; moreover, in the placement area of the cup body assembly, the height of other areas is the same except for the protruding parts. When water flows to the vicinity of the lower coupler, the water cannot flow to a lower place and cannot be drained, which will increase the risk of water flowing into the main machine. For another type with a motor connected to the lower part of the mixing cup, the overall height of the mixing cup assembly is relatively high. The main machine is usually provided with a sunken cavity for installing the mixing cup assembly to improve the stability of the machine operation and prevent the mixing cup assembly from tipping over. The lower coupler is disposed at the bottom of the cavity. The overall height of such a main machine is relatively high. When a user wipes the operation panel of the main machine shell, it is not easy for the cleaning water to enter the cavity. However, when the mixing cup assembly is placed in the cavity, there is a certain radial gap between the mixing cup assembly and the cavity. When water flows down the outer surface of the mixing cup assembly, the water may still flow into the cavity, and there is a risk that the water flows downward through the installation gap of the lower coupler into the main machine and damages the electronic devices inside the main machine, which is also not conducive to extending the service life of the machine. Summary of the Utility Model

[0004] In order to solve the technical problem that there is a risk of water ingress in the main machine in the prior art, which may cause damage to the electronic devices inside the main machine, the utility model provides a food processor. By providing a water leakage hole in the main machine, the function of draining water from the main machine is provided, so that the liquid flowing into the accommodation cavity can be discharged in time, and the liquid can be prevented from entering the main machine and damaging the electronic devices inside the main machine. In addition, by disposing the water leakage hole at a position close to the lower part at the bottom of the accommodation cavity, the water guiding can be strengthened to promote the water flow to the water leakage hole, and thus the drainage effect can be improved.

[0016] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0017] 1. The food processor of the present utility model is provided with a water leakage hole. When liquid flows to the bottom of the accommodating cavity, the liquid can be discharged through the water leakage hole, which can prevent the liquid from flowing into the interior of the main machine and damaging the electronic devices inside the main machine, and can improve the overall performance and service life of the machine. Since the water leakage hole is arranged close to the edge of the accommodating cavity and is at a lower elevation, it is convenient for the liquid to flow towards the water leakage hole and be discharged, ensuring the drainage effect. By discharging the liquid in time, it can prevent the liquid from flowing into the main machine through the gap at the installation position of the lower coupler, and can solve the problem of water ingress into the main machine.

[0018] 2. As a preferred embodiment, the water leakage hole is arranged at the lowest position of the bottom wall of the accommodating cavity. Based on this, the liquid flowing into the accommodating cavity flows from a high position to a low position, and finally can be discharged through the water leakage hole at the lowest position, which can ensure sufficient drainage and avoid liquid residue.

[0019] 3. As a preferred embodiment, an installation cavity is formed between the bottom of the accommodating cavity and the bottom of the main machine, and a drainage channel is arranged in the installation cavity to communicate the water leakage hole with the outside. Electronic devices such as a power board are arranged in the installation cavity. By providing a drainage channel, a drainage path for isolating the installation cavity is provided, which can prevent the liquid from flowing into the installation cavity and damaging the electronic devices inside.

[0020] As a preferred embodiment under this embodiment, a drain pipe integrally extends downward from the bottom of the water leakage hole to form the drainage channel. By providing a drain pipe integrated with the water leakage hole, the structural configuration can be simplified, there is no need to set up a dedicated drainage channel, and the installation between the water leakage hole and the dedicated drainage channel can also be omitted.

[0021] 4. As a preferred embodiment, the installation position is provided with an installation opening for inserting the lower coupler, and a seal is arranged between the lower coupler and the installation opening. By providing a seal, it can prevent the liquid flowing to the bottom of the accommodating cavity from flowing into the main machine through the gap between the lower coupler and the installation opening, further reducing the risk of water ingress into the main machine and improving the reliability of the machine during use.

[0022] 5. As a preferred embodiment, the installation position is provided with an installation boss, and the lower coupler is arranged on the installation boss. By arranging the lower coupler on the installation boss, the installation height of the lower coupler is raised. Since the liquid is not easily flow to the installation boss, the probability of the liquid flowing into the main machine through the gap between the installation boss and the lower coupler can be reduced, protecting the electronic devices inside the main machine.

[0023] 6. As a preferred embodiment, the water leakage hole is arranged on the opposite side of the lower coupler. By arranging the water leakage hole and the lower coupler opposite to each other, both can be arranged close to the edge of the accommodating cavity, which can avoid increasing the radial size of the accommodating cavity and promote the miniaturization of the main machine.

[0024] 7. As a preferred embodiment, a positioning boss is provided on the bottom wall of the accommodation cavity, and the cup body assembly is provided with a recess that is inserted and cooperated with the positioning boss. An air inlet and / or an air outlet is provided between the positioning boss and the recess. When the cup body assembly is installed on the main body, the insertion and cooperation of the positioning boss and the recess is conducive to the positioning and installation of the cup body assembly, can reduce the installation difficulty, avoid the need for multiple adjustments of the cup body assembly to be installed in place, and improve the user experience; by providing an air inlet and / or an air outlet between the positioning boss and the recess, while improving the space utilization rate, it can meet the heat dissipation requirements of the electronic devices in the main body and the cup body assembly during the operation of the machine, enable the electronic devices to work at an appropriate temperature, and ensure their use performance.

[0025] 8. As a preferred embodiment, the cup body assembly includes a stirring cup and a cup body housing provided below the stirring cup. The stirring cup is provided with a crushing knife, a motor for driving the crushing knife to rotate is provided in the cup body housing, a heat dissipation air duct is provided in the cup body housing, a power supply board is provided in the main body, and the power supply board includes a high-temperature area provided with an IPM module, and an air inlet air duct is provided in the high-temperature area. Based on this, the heat dissipation air duct in the cup body housing is conducive to the heat dissipation of the motor, so that the heat of the motor can be discharged in time through the heat dissipation air duct, avoiding heat residue, and improving the heat dissipation effect of the motor; by providing an air inlet air duct in the high-temperature area, centralized and rapid heat dissipation of the high-temperature area can be realized. Under the action of the air inlet air duct, not only can the aggregation of air flow be ensured to improve the uniformity of heat dissipation in the high-temperature area, but also it is beneficial to reduce noise; setting an air inlet air duct in the high-temperature area can improve the heat dissipation effect compared with the conventional air flow flowing through the power supply board in an open space, and can ensure the heat dissipation effect for the high-temperature area with high heat dissipation requirements.

[0026] As a preferred embodiment under this embodiment, an air outlet air duct is further provided in the main body for connecting the heat dissipation air duct with the air outlet hole on the main body. By providing the air outlet air duct, during the operation of the machine, the heat of the motor can be discharged through the heat dissipation air duct - air outlet air duct - air outlet hole, which can ensure the heat dissipation efficiency, and at the same time can avoid part of the heat remaining in the main body causing the temperature rise of the electronic devices in the main body to be too high and affecting their use performance and service life, and can improve the heat dissipation reliability.

[0042] As Figures 1 to 5 shown, the present application provides a food processor, which includes a main body 10 and a cup assembly 11 installed on the main body 10. The cup assembly 11 is provided with an upper coupler 12, and the main body 10 is provided with a lower coupler 13. The main body 10 is provided with a receiving cavity 14 for placing the cup assembly 11. The bottom wall of the receiving cavity 14 decreases in height from the center of the receiving cavity 14 to the edge. The bottom wall of the receiving cavity 14 is provided with an installation position for installing the lower coupler 13 and a water leakage hole 15. The water leakage hole 15 is arranged close to the edge of the receiving cavity 14. The distance from the center of the installation position to the center of the receiving cavity 14 is less than the distance from the center of the water leakage hole 15 to the center of the receiving cavity 14.

[0043] In the food processor of the present application, by providing a water leakage hole 15, when liquid flows to the bottom of the accommodation cavity 14, the liquid can be discharged through the water leakage hole 15, preventing the liquid from flowing into the interior of the main machine 10 and damaging the electronic devices inside the main machine 10, thereby improving the overall performance and service life of the machine. Since the water leakage hole 15 is provided near the edge of the accommodation cavity 14 and is at a lower elevation, it is convenient for the liquid to flow towards the water leakage hole 15 and be discharged, ensuring the drainage effect. By discharging the liquid in a timely manner, it can be avoided that the liquid flows into the main machine 10 through the gap at the installation position of the lower coupler 13, thus solving the problem of water ingress into the main machine 10.

[0044] It should be noted that, for example, the main machine 10 is provided with an installation cavity, and electronic devices such as a power board are arranged in the installation cavity. The water leakage hole 15 is communicated with the outside, and when discharging liquid through the water leakage hole 15, the liquid will not enter the installation cavity, so the electronic devices in the installation cavity will not be damaged.

[0045] As Figure 2 or Figure 3 shown, the bottom wall of the accommodation cavity 14 is in a shape that is high in the middle and low around. By arranging the water leakage hole 15 near the edge of the accommodation cavity 14, it is beneficial for the liquid to flow from a high position to a low position and then reach the water leakage hole 15. The water leakage hole 15 is closer to the edge of the accommodation cavity 14 than the installation position of the lower coupler 13. In this way, when the liquid flows down along the side wall of the accommodation cavity 14, the liquid is more likely to flow towards the water leakage hole 15 and less likely to flow into the interior of the main machine 10 through the installation position. Figure 1 Illustrates the path for the liquid in the accommodation cavity 14 to be discharged through the water leakage hole 15 and the drainage channel 19. The water leakage hole 15 can be provided with one or more. When there is one water leakage hole 15 provided on the same side of the installation position, the water leakage hole 15 is provided on the radially outer side of the installation position.

[0046] As a preferred embodiment, as Figure 2 shown, the water leakage hole 15 is provided at the lowest position of the bottom wall of the accommodation cavity 14. Based on this, the liquid flowing into the accommodation cavity 14 flows from a high position to a low position and can finally be discharged through the water leakage hole 15 at the lowest position, ensuring sufficient drainage and avoiding liquid residue.

[0047] As a preferred embodiment, an installation cavity is formed between the bottom of the accommodation cavity 14 and the bottom of the main machine 10, and a drainage channel 19 is provided in the installation cavity to communicate the water leakage hole 15 with the outside.

[0048] As Figure 1 shown, the main machine 10 includes a main body housing 16 with an opening at the top and a concave main body cover 17 installed at the opening. The main body cover 17 is recessed to form the accommodation cavity 14. An installation cavity is formed between the main body cover 17 and the main body housing 16, and electronic devices such as a power board are arranged in the installation cavity. By providing the drainage channel 19, a drainage path for isolating the installation cavity is provided, preventing the liquid from flowing into the installation cavity and damaging the electronic devices inside.

[0049] As a preferred embodiment of this embodiment, a drain pipe 18 extends integrally downward from the bottom of the water leakage hole 15 to form a drainage channel 19. As Figure 2 shown, by providing the drain pipe 18 integrally with the water leakage hole 15, the structural configuration can be simplified, there is no need to provide a dedicated drainage channel, and the installation between the water leakage hole 15 and the dedicated drainage channel is also omitted. Specifically, a through hole is provided at the bottom of the main body housing 16, and the bottom of the drain pipe 18 can be connected to the through hole.

[0050] As a preferred embodiment, the installation position is provided with an installation opening 20 for inserting the lower coupler 13, and a seal 21 is provided between the lower coupler 13 and the installation opening 20. As Figure 3 shown, by providing the seal 21, it is possible to prevent the liquid flowing to the bottom of the accommodation chamber 14 from flowing into the main body 10 through the gap between the lower coupler 13 and the installation opening 20, which can further reduce the risk of water ingress into the main body 10 and improve the reliability of the machine during use.

[0051] As a preferred embodiment, the installation position is provided with an installation boss 22, and the lower coupler 13 is arranged on the installation boss 22. As Figure 4 shown, by arranging the lower coupler 13 on the installation boss 22, the installation height of the lower coupler 13 is increased. Since the liquid is not likely to flow onto the installation boss 22, the probability of the liquid flowing into the main body 10 through the gap between the installation boss 22 and the lower coupler 13 can be reduced, so that the electronic components in the main body 10 are protected.

[0052] As a preferred embodiment, the water leakage hole 15 is arranged on the opposite side of the lower coupler 13. As Figure 4 shown, by arranging the water leakage hole 15 and the lower coupler 13 opposite to each other, both of them can be arranged close to the edge of the accommodation chamber 14, which can avoid increasing the radial dimension of the accommodation chamber 14 to promote the miniaturization of the main body 10. Specifically, the water leakage hole 15 and the lower coupler 13 are not necessarily arranged directly opposite to each other. For example, the water leakage hole 15 is arranged on a semicircular path of the accommodation chamber 14, and the lower coupler 13 is arranged on the other semicircular path of the accommodation chamber 14.

[0053] As a preferred embodiment, the bottom wall of the accommodation chamber 14 is provided with a positioning boss, the cup body assembly 11 is provided with a recess that is inserted and matched with the positioning boss, and an air inlet and / or an air outlet is provided between the positioning boss and the recess.

[0054] When the cup body assembly 11 is installed on the main body 10, the positioning installation of the cup body assembly 11 is facilitated through the plug-in fit of the positioning boss and the recess, which can reduce the installation difficulty, avoid the need to adjust the cup body assembly 11 multiple times to be properly installed, and improve the user experience. By providing an air inlet and / or an air outlet between the positioning boss and the recess, while improving the space utilization rate, it can meet the heat dissipation requirements of the electronic devices in the main body 10 and the cup body assembly 11 during the operation of the machine, enabling the electronic devices to work at an appropriate temperature and ensuring their performance.

[0055] In some embodiments, such as Figure 4 and Figure 5 shown, a first boss 23 and a second boss 24 are provided at the bottom of the main body cover 17. An air inlet is provided on the side wall of the first boss 23, and an air outlet is provided on the side wall of the second boss 24. Upper concave first and second recesses for the first boss 23 and the second boss 24 to be inserted into are provided at the bottom of the cup body assembly 11. An air inlet is provided on the side wall of the first recess, and an air outlet is provided on the side wall of the second recess. When the cup body assembly 11 is installed on the main body 10, the air inlet communicates with the air inlet, and the air outlet communicates with the air outlet. Then, the air flowing into the main body 10 can flow into the cup body assembly 11 (specifically, into the cup body housing 112) through the air inlet - air inlet, and the heat dissipation of the motor 114 can be carried out. At the same time, the heat of the motor 114 can flow back into the main body 10 through the air outlet - air outlet, and then can be discharged through the exhaust air duct in the main body 10 to complete the heat dissipation.

[0056] As a preferred implementation manner, the cup body assembly 11 includes a stirring cup 111 and a cup body housing 112 provided below the stirring cup 111. A crushing blade 113 is provided on the stirring cup 111, a motor 114 for driving the crushing blade 113 to rotate is provided in the cup body housing 112, a heat dissipation duct is provided in the cup body housing 112, a power supply board is provided in the main body 10, the power supply board includes a high-temperature area provided with an IPM module, and an air inlet duct is provided in the high-temperature area. Based on this, the heat dissipation duct in the cup body housing 112 is beneficial to the heat dissipation of the motor 114, so that the heat of the motor 114 can be discharged in time through the heat dissipation duct, avoiding heat residue and improving the heat dissipation effect of the motor 114. By providing an air inlet duct in the high-temperature area, centralized and rapid heat dissipation of the high-temperature area can be realized. Under the action of the air inlet duct, not only can the aggregation of air flow be ensured to improve the uniformity of heat dissipation in the high-temperature area, but also the noise can be reduced. By providing an air inlet duct in the high-temperature area, compared with the conventional air flow flowing through the power supply board in an open space, the heat dissipation effect can be improved, and the heat dissipation effect can be ensured for the high-temperature area with high heat dissipation requirements.

[0057] It can be understood that the power supply board further includes a low-temperature area, for example. When the air flow flows to the low-temperature area, the air flow can flow in an open space. On the one hand, because the heat dissipation requirement of the low-temperature area is low, and on the other hand, not all modules in the low-temperature area need heat dissipation. Such a setting is more conducive to the air flow dissipating heat from the low-temperature area, and at the same time, the air flow can flow to the high-temperature area faster and more, so as to strengthen the heat dissipation for the high-temperature area.

[0058] The low-temperature area is distributed with a switching power supply, a control module, etc., for example. The high-temperature area is distributed with an IPM module (i.e., intelligent power module, which is a highly integrated power electronic device that integrates power switching devices, drive circuits, and fault detection circuits such as overvoltage, overcurrent, and overheating), a thyristor module, a rectifier module, etc., for example. The motor 114 of the present application can adopt a variable-frequency motor 114, for example. It has a wide speed regulation range, can meet the requirements of various working conditions, can improve the use performance of the food processor, and the variable-frequency motor 114 has the advantage of low noise, which is beneficial to reducing the working noise.

[0059] As a preferred embodiment of this embodiment, an air outlet duct is further provided in the main body 10, which is used to connect the heat dissipation duct with the air outlet hole on the main body 10. By providing the air outlet duct, during the operation of the machine, the heat of the motor 114 can be discharged through the heat dissipation duct - air outlet duct - air outlet hole, which can ensure the heat dissipation efficiency. At the same time, it can avoid some heat remaining in the main body 10 and causing the temperature rise of the electronic devices in the main body 10 to be too high, which affects their use performance and service life, and can improve the heat dissipation reliability.

[0060] The technical solution protected by the present utility model is not limited to the above embodiments. It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
