Description

Technical Field

[0001] This utility model relates to the field of food processors, specifically a steam-heated food processor. Background Technology

[0002] Existing technology includes a food processor with a steam heating function. The food processor includes a base and a blending cup. The blending cup is mounted on the base and contains a blending blade that is connected to a drive motor in the base via a transmission blade holder. The drive motor stirs and grinds the ingredients in the blending cup. The base also has a water tank and a steam generator. The steam generator heats and evaporates water from the water tank to form high-temperature steam. The high-temperature steam is introduced into the blending cup to heat the ground ingredients, ultimately creating a ready-to-eat food. To facilitate the pouring out of the food processed by the blending cup, the blending cup and the base are detachable. Therefore, the base is equipped with a steam nozzle, and the bottom of the blending cup is equipped with a steam inlet. The steam nozzle and the steam inlet are connected to the steam generator in the base through a plug-in connection. For safety, the steam nozzle is equipped with a steam inlet valve mechanism. When the blending cup is removed from the base, the steam inlet valve mechanism blocks the steam nozzle to prevent the high-temperature steam from burning the user. However, if the steam generator is still in a high-temperature and high-pressure state inside after the steam inlet valve mechanism blocks the steam outlet, the steam channel inside the base will also continue to be in a high-pressure state. During the duration of this state, there is a certain threat to the safety performance of the food processor. Especially when the mixing cup is put back immediately, high-temperature steam will suddenly be ejected at the moment the steam outlet and steam inlet are reconnected, and there is still a risk of high-temperature steam ejection burning the human body. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a steam-heated food processor.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A steam-heated food processor includes a blending cup, a water tank, and a base. The blending cup includes a cup body, a cup lid, and a blending blade assembly housed within the cup body. A steam inlet is located at the bottom of the cup body. A water inlet is located at the bottom of the water tank. The base includes a mounting base for mounting the blending cup and a water inlet for mounting the water tank. A motor, a water pump, and a steam generator are housed inside the base. A water inlet connector is provided on the water inlet connector, which is connected to the water pump via a water pipe. The water pump is connected to the input end of the steam generator. A steam outlet is arranged on the mounting base, which is connected to the steam inlet. The steam supply pipe connects to the output end of the steam generator; the motor shaft of the motor passes through the machine base and is connected to a coupling located on the mounting base, the coupling being driven by the stirring blade assembly; the steam outlet nozzle is equipped with a steam inlet valve mechanism, which opens and connects when the steam outlet nozzle is connected to the steam inlet; the steam supply pipe is also connected to a steam supply device, which includes a first steam inlet, a second steam inlet, and a steam vent. The steam supply pipe is arranged in sections and connects to the first steam inlet and the second steam inlet respectively to achieve communication. The steam vent is equipped with a steam vent valve mechanism, and the steam vent is connected to a water connector through a steam vent pipe, thereby connecting to the inside of the water tank.

[0006] The steam supply device also includes a fourth steam inlet, and a temperature detector is installed inside the fourth steam inlet.

[0007] The vent valve mechanism includes a sealing element and a spring element. The sealing element is arranged toward the flow channel between the first vent and the second vent and is blocked from connecting the vent and the flow channel by the force applied by the spring element.

[0008] The steam inlet valve mechanism includes a sealing valve core and a spring. The spring is located below the sealing valve core and presses the sealing valve core against the top outlet of the steam outlet nozzle.

[0009] The water inlet seat has an insertion cavity for insertion into the bottom of the water tank, and the water inlet connector is arranged inside the insertion cavity.

[0010] The mounting base has a limiting cavity for inserting the bottom of the stirring cup, the steam outlet is arranged in the limiting cavity, and the motor shaft of the motor passes through the limiting cavity and is connected to the coupling.

[0011] The bottom of the limiting cavity is provided with a drain outlet, and the machine base is provided with a drain channel that connects to the drain outlet. The outlet of the drain channel is located at the bottom of the machine base.

[0012] The top of the mounting base is covered with a soundproof cover, and the internal cavity of the soundproof cover can accommodate the stirring cup.

[0013] The beneficial effects of this utility model are as follows: This utility model is equipped with a steam venting device with a pressure relief function. This steam venting device connects the steam generator and the steam outlet. When the mixing cup is removed from the base and the steam outlet is blocked by the steam inlet valve mechanism, if the steam generator is still in a high temperature and high pressure state, it will trigger the steam venting valve mechanism in the steam venting device to open, thereby relieving the pressure in the steam channel and solving the safety risks that existed in the past. In addition, the steam vent is connected to the water tank through the steam venting pipe. After the steam venting valve mechanism is opened, the water vapor released from the pressure will be discharged into the water tank and will not come into contact with the user, further ensuring the safety of the food processor.

[0026] Reference Figures 1 to 11 A food processor includes a blending cup 1, a water tank 2, a base 3, and a soundproof cover 10.

[0027] The base 3 includes a mounting base 31 for mounting the stirring cup 1 and a water inlet base 32 for mounting the water supply tank 2. The base 3 is equipped with a motor 4, a water pump 5 and a steam generator 6.

[0028] A water inlet connector 7 is provided on the water inlet base 32; a water inlet nozzle 21 is provided at the bottom of the water tank 2. When the water tank 2 is installed on the water inlet base 32, the water inlet nozzle 21 is connected to the water inlet connector 7. The water inlet connector 7 is connected to the water pump 5 through a water pipe, and the water pump 5 is connected to the input end 61 of the steam generator 6.

[0029] A steam outlet nozzle 8 is arranged on the mounting base 31. The motor shaft of the motor 4 passes through the inside of the base 3 and is connected to a coupling 41 located on the mounting base 31. The stirring cup 1 includes a cup body 11, a cup lid 12, and a stirring blade assembly 13 placed inside the cup body 11. A steam inlet 14 is provided at the bottom of the cup body 11. When the stirring cup 1 is installed on the mounting base 31, the stirring blade assembly 13 is connected to the coupling 41 for transmission, and the steam inlet 14 is connected to the steam outlet nozzle 8. The steam outlet nozzle 8 is connected to the output end 62 of the steam generator 6 through a steam pipe, and a steam inlet valve mechanism is provided inside the steam outlet nozzle 8. The steam inlet valve mechanism will only open when the steam outlet nozzle 8 is connected to the steam inlet 14. That is, after the stirring cup 1 is removed from the mounting base 31, the steam outlet nozzle 8 will be blocked by the steam inlet valve mechanism to prevent the ejection of high-temperature steam from burning the human body. A steam supply device 9 is also connected to the steam pipe. The steam supply device 9 includes a first steam inlet 91, a second steam inlet 92, and a steam vent 93. The steam supply pipe is arranged in sections and is connected to the first steam inlet 91 and the second steam inlet 92 respectively. That is, the steam supply pipe is divided into two sections. One section connects the first steam inlet 91 to the output end 62 of the steam generator 6, and the other section connects the second steam inlet 92 to the steam outlet 8. The steam vent 93 is equipped with a steam vent valve mechanism. When the mixing cup 1 is removed from the base 3 and the steam outlet 8 is blocked by the steam inlet valve mechanism, if the steam generator 6 is still in a high temperature and high pressure state, the steam vent valve mechanism in the steam vent 93 will be triggered to open, thereby relieving the pressure in the steam channel and solving the safety risk problem that existed in the past. The steam vent 93 is connected to the water connector 7 through the steam vent pipe 95 and then to the inside of the water tank 2. After the steam vent valve mechanism is opened, the water vapor released from the pressure will be discharged into the water tank 2 and will not come into contact with the user, further ensuring the safety of the food processor.

[0030] As a preferred embodiment of this utility model, the steam supply device 9 also includes a third steam inlet 94, in which a temperature detector 96 is installed. In this embodiment, the temperature detector 96 is a common NTC temperature sensor, which can feed back the temperature signal in the steam channel to the control module of the food processor in real time for data processing. It can monitor and control the working status of the steam generator 6, and can also display temperature information for the user.

[0031] In this embodiment, the vent valve mechanism includes a sealing element 97 and an elastic element 98. The sealing element 97 is arranged towards the flow channel between the first steam inlet 91 and the second steam inlet 92 and is blocked from the connection between the vent port 93 and the flow channel by the force applied by the elastic element 98. The torque of the elastic element 98 is set so that when the gas pressure in the flow channel is greater than 0.1 MPa, the gas pressure can push the sealing element 97 to overcome the pressure, causing the elastic element 98 to compress and move the sealing element 97 to open the connection between the vent port 93 and the flow channel.

[0032] In this embodiment, the steam inlet valve mechanism includes a sealing valve core 81 and a spring 82. The spring 82 is located below the sealing valve core 81, pressing the sealing valve core 81 against the top outlet of the steam outlet 8. A downwardly extending push rod is provided inside the steam inlet 14. When the steam outlet 8 is inserted into the steam inlet 14, the push rod inserts into the top outlet of the steam outlet 8, opening the sealing valve core 81 and connecting the steam outlet 8 to the steam inlet 14.

[0033] To ensure the stability of the installation of the mixing cup 1 and the water tank 2, a recessed chamber is used for installation of both. Specifically, the water inlet base 32 has an insertion cavity 321 for the bottom of the water tank 2 to be inserted. The water inlet connector 7 is arranged inside the insertion cavity 321, i.e., on the bottom wall of the insertion cavity 321. Due to the existence of the insertion cavity 321, any leakage that occurs when the water tank 2 is removed will only flow into the insertion cavity 321 and will not flow to other locations. In this embodiment, the mounting base 31 has a limiting recess 311 for the bottom of the mixing cup 1 to be inserted. The steam outlet 8 is arranged inside the limiting recess 311. The motor shaft of the motor 4 passes through the limiting recess 311 and is then connected to the coupling 41. Preferably, the bottom of the limiting cavity 311 is provided with a drain outlet 33, and the machine base 3 has a drainage channel inside that connects to the drain outlet 33. The outlet 34 of the drainage channel is located at the bottom of the machine base 3, and all water falling into the limiting cavity 311 will be discharged to the outside of the machine base 3 through the drain outlet 33. More preferably, a soundproof cover 10 is installed on top of the mounting base 31. The internal cavity of the soundproof cover 10 can accommodate the mixing cup 1. When stirring is performed in the mixing cup 1, the soundproof cover 10 can block the noise generated by stirring in the mixing cup 1, thereby improving the user experience.
