Description

Technical Field

[0001] The utility model belongs to the field of robots, and in particular relates to an intelligent cooking robot. Background Art

[0002] The cooking robot can automatically perform a variety of cooking, easily realizing the automation and fun of the cooking process. Existing cooking robots still need to manually add seasonings during the cooking process. Even if there is a seasoning box, the structure is complex and the cleaning work is cumbersome. In addition, it may only be possible to add liquid seasonings because it is too difficult and costly to deliver the seasonings into the pot. The water addition in the pot of the existing cooking robot is not accurate. When slow-cooking, the machine is prone to not adding water in time, causing it to dry out. Because the pressure sensor that monitors the water content is only applicable to pressure cookers, the intelligent cooking robot is not suitable for installation; it is too difficult to always keep the same water level during slow cooking. Therefore, the existing cooking robots have the disadvantages of not being able to automatically add seasonings and not being able to control the water content in the pot. Utility Model Content

[0003] The utility model aims to provide an intelligent cooking robot to solve the technical problems that the existing cooking robots cannot automatically add seasonings and cannot control the water content in the pot.

[0004] In order to solve the above technical problems, the specific technical solutions of the utility model are as follows:

[0005] An intelligent cooking robot comprises a robot body, a water tank and a water level alarm; the water level alarm comprises a water level monitor and a buzzer; the water level monitor is attached to the water tank to monitor the water level in the water tank; the buzzer is connected to the water level monitor;

[0006] The top layer of the robot body is a platform, which is supported on the ground by pillars; a DC motor is installed just above the center of the platform; a water pump and a stepper motor are fixedly installed below the platform; the water pumping pipe of the water pump is connected to the water tank, and the screw rod of the stepper motor is connected to the seasoning box; the bottom of the robot body is a weighing device, a heating pot is installed on the weighing device, and a pot brush is placed inside the heating pot; the pot brush includes a brush handle and a brush head, the brush head is connected to the lower end of the brush handle, and handles are extended from both ends of the brush head, and the length of the brush handle at each end is less than the radius of the pot;

[0007] The upper end of the pot brush handle is connected to the screw of the DC motor. When the DC motor is working, its screw will drive the pot brush to rotate and stir the ingredients. The heating pot is covered with a pot lid, and a temperature controller is installed on the side of the heating pot to facilitate accurate measurement and control of temperature.

[0008] The pot cover is provided with a hole and a rectangular groove; the holes are respectively located directly below the water outlet of the pump and directly below the seasoning box; the length of the long side of the groove is greater than the radius of the pot cover;

[0009] By controlling the screw rod driven by the stepper motor, the screw rod is fixed and locked with the bottom surface of the seasoning box. The rotation of the screw rod drives the rotation of the seasoning box, and the fallen seasoning will pass through the small hole on the pot cover and finally reach the pot.

[0010] Furthermore, the seasoning box is cylindrical, hollow inside, and has a cutout on the side, which is perpendicular to the bottom surface of the cylinder. The existence of the cutout facilitates the smooth pouring of the seasoning. Three layers of superimposed baffles are provided above the cutout, including a lower fixed baffle, a middle slidable baffle, and an upper fixed baffle. The lower fixed baffle and the upper fixed baffle are a whole, which are fixed and perpendicular to the bottom surface, and the two long sides of the lower fixed baffle and the upper fixed baffle are respectively tightly fitted with the top surface of the cylindrical seasoning box, one of the wide sides is tightly fitted with the side of the seasoning box, and the other wide side is kept at a certain distance from the side. The middle slidable baffle is a rectangular baffle with a protrusion below the left wide side, and the role of the protrusion is to have a suitable force point when sliding the middle slidable baffle. The installation method is to directly clamp the middle slidable baffle between the gap between the lower fixed baffle and the upper fixed baffle to ensure that it can only slide horizontally and prevent it from moving by itself through friction. Adjusting the middle sliding baffle can control the amount of seasoning that pours out when the seasoning box is rotated. The bottom surface and the three-layer baffle of the seasoning box can be regarded as the bottom. The side and top surface of the seasoning box can be regarded as the lid, which is a cylindrical lid with a notch on the side. The installation process consists of pushing the bottom of the seasoning box into the lid. The installation is completed when the baffle touches the top surface and cannot be pushed in further. To open the seasoning box, just push the bottom in the opposite direction with force in the notch. Once pushed in, the friction between the bottom and the lid will prevent them from falling out. (The diameter of the top surface of the lid is equal to the diameter of the bottom, and the diameter of the bottom surface of the lid is slightly smaller than the diameter of the bottom, but there is a cut on the side of the lid to make the lid have a certain degree of ductility, so the bottom can still be pushed into the lid. After pushing in, the side of the lid will form a certain pressure on the bottom. Since the greater the pressure, the greater the friction, the friction between the bottom and the side of the lid will prevent them from falling out).

[0011] Furthermore, the seasoning box is a square box without a lid.

[0012] Furthermore, two sections of heating iron rings are installed in the heating pot, one section is powered on for low-power heating, and the other two sections are powered on for high-power heating; the temperature controller is connected to the outer iron ring at the bottom of the heating pot.

[0013] Furthermore, a slope is designed around the hole so that the seasoning can be fully added without being scattered around the small hole.

[0014] The beneficial effects of the utility model are:

[0015] 1. In order to achieve the addition of solid and liquid seasonings, a seasoning addition system is designed. A precisely controlled stepper motor is used, and the motor's screw is fixed at the center of the circle on the bottom of the seasoning box. By controlling the rotation of the stepper motor screw, precise control of the seasoning can be achieved. The pot lid and pot are located directly below the seasoning box, and the seasoning is added to the pot through the small hole on the pot lid. Liquid seasonings and pure water need to be added manually to two water tanks. They are extracted by a pump and finally added to the pot through the small hole on the pot lid. The order of adding seasonings can be automatically controlled according to the cooking order of the ingredients. The addition of solid seasonings is achieved through delay control and stepper motors, while the addition of liquid seasonings is also achieved through delay control and pumps. In order to ensure that the seasoning can be added to the pot smoothly, we set a small hole on the pot lid under each seasoning box and small pump, and designed a slope around it. This ensures that the seasoning can be fully added to the pot while maintaining the heat preservation of the pot lid. This design ensures that spices and liquid seasonings can be added to the cooking robot's pot accurately and in a timely manner, thereby achieving precise cooking of ingredients.

[0016] 2. Realize different power heating of the pot. Two sections of heating iron rings are added under the pot. After power is turned on, the electrical energy will be converted into thermal energy. One section is powered on for low power heating, and two sections are powered on for high power heating.

[0017] 3. Realize constant temperature control in the pot. The temperature controller is connected to a heating iron ring. When the temperature is lower than the critical value, the iron ring is powered on and starts heating. When the temperature is higher than the rated value, the iron ring is powered off and stops heating.

[0018] 4. It solves the problem of overflow and drying up in the wok when frying or stewing. Use a pump to add water at regular intervals, and place a weight monitor under the pot. When the weight exceeds the rated value, stop adding water to keep the water content in a constant range to prevent overflow and drying up.

[0019] 5. Solve the problem that insufficient water in the water storage box can easily affect the taste and safety of dishes. A water level monitor is installed and connected in series with the switch and buzzer. When the sensor detects liquid / object, it outputs a low-level signal; when it detects that there is no liquid / object left, it outputs a high-level signal until the liquid level is full / the object is in place and the low-level output is restored. When the liquid level is too low, the buzzer will sound to remind you to add water. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0037] like Figure 1 As shown, the intelligent cooking robot includes a robot body.

[0038] The water level alarm 11 is located in front of the two water storage tanks 10. The water level alarm 11 is provided with a water level monitor 12, which is pasted on the water storage tank 10 and functions to monitor the water levels in the two water storage tanks.

[0039] The top layer of the robot body is a disc, which is supported on the ground by three pillars. The DC motor 1 is installed just above the center of the disc; below the disc, the fan-shaped part close to the water tank 10 is fixed with the pump 3 and the stepper motor 2 in sequence, and they are fixed in different positions. The water pipe of the pump 3 is connected to the water tank, and the screw rod of the stepper motor 2 is connected to the seasoning box 4 for adding seasoning.

[0040] At the bottom of the robot body is a weighing device 9, which is used to measure the weight of all the ingredients in the pot. A heating pot 5 is placed on the weighing device 9, and a pot brush 7 is arranged inside the heating pot 5. The upper end of the pot brush 7 is connected to the lead screw of the DC motor 1. When the DC motor 1 is working, its lead screw will drive the pot brush 7 to rotate and stir the ingredients. The heating pot 5 is covered with a pot cover 6, and a temperature controller 8 is installed on the side of the heating pot 5 to facilitate accurate measurement and control of temperature.

[0041] The pot cover 6 is circular in shape, with two square holes, two round holes, and a rectangular groove. In order to smoothly add seasonings into the pot, we first designed four holes on the pot cover 6. The two square holes are located directly below the two seasoning boxes 4 (located directly to the left of the pot cover 6 and arranged vertically), and the two round holes are located directly below the water outlets of the two pumps 3 (located directly to the right of the pot cover 6 and arranged vertically). Slopes are designed around the small holes so that the seasonings can be fully added and not scattered around the small holes. Even if the seasoning falls on the slope, it can automatically slide into the pot. In order to ensure the heat preservation of the pot cover 6, the small hole cannot be opened too large. In order to smoothly take out the pot cover 6 from the horizontal direction and the pot brush 7 can work normally when the pot cover 6 is closed, we designed a groove on the pot cover 6. The long side length of the groove is greater than the radius of the pot cover 6, and this groove passes through the center of the circle. The pot cover is like Figure 8 shown.

[0042] The seasoning box is cylindrical, hollow inside, with a cutout on the side, which is perpendicular to the bottom surface of the cylinder. The cutout allows the seasoning to be poured out smoothly. Three layers of overlapping baffles are arranged above the cutout, including a lower fixed baffle, a middle sliding baffle, and an upper fixed baffle. The lower fixed baffle and the upper fixed baffle are a whole, fixed and perpendicular to the bottom surface, and the two long sides of the lower fixed baffle and the upper fixed baffle are tightly fitted with the top surface of the cylindrical seasoning box, one of the wide sides is tightly fitted with the side of the seasoning box, and the other wide side is kept at a certain distance from the side. The middle sliding baffle is a rectangular baffle with a raised block below the left wide side. The role of the raised part is to have a suitable force point when sliding the middle sliding baffle. The installation method is to directly clamp the middle sliding baffle between the gap between the lower fixed baffle and the upper fixed baffle to ensure that it can only slide horizontally and prevent it from moving by itself through friction. By adjusting the middle sliding baffle, the amount of seasoning that is poured out when the seasoning box rotates can be controlled. Figure 5 The middle sliding baffle of the seasoning box is folded and Fig.12 The middle sliding baffle of the seasoning box is shown as open. The bottom surface of the seasoning box and the three-layer baffle can be regarded as the bottom. Fig.14 The bottom of the seasoning box is shown. The sides and top of the seasoning box can be regarded as the lid, which is a cylindrical lid with a notch on the side. Fig.13 The spice box lid is shown. The installation process involves pushing the bottom of the spice box into the lid. Fig.15 The installation process of the lid and bottom of the seasoning box is shown. The installation is completed until the baffle touches the top surface and cannot be pushed in further. To open the seasoning box, just push the bottom in the opposite direction with force in the notch. Once pushed in, the friction between the bottom and the lid will prevent them from falling off. (When designed, the diameter of the top surface of the lid is equal to the diameter of the bottom, and the diameter of the bottom surface of the lid is slightly smaller than the diameter of the bottom, but there is a cut on the side of the lid to make the lid have a certain degree of ductility, so the bottom can still be pushed into the lid. After pushing it in, the side of the lid will form a certain pressure on the bottom. Since the greater the pressure, the greater the friction, the friction between the bottom and the side of the lid will prevent them from falling off).

[0043] The present invention precisely controls the screw rod driven by the stepper motor, and the screw rod is fixed and locked with the center of the bottom surface of the seasoning box. The rotation of the screw rod drives the rotation of the seasoning box, and the fallen seasoning will pass through the small hole on the pot cover 6 and finally reach the pot, thereby achieving relatively precise addition of seasoning.

[0044] like Figure 7 As shown, liquid seasoning and purified water need to be manually added into two water storage tanks 10 , and the liquid seasoning and purified water will be extracted by the pump 3 , and finally pass through the small hole on the pot cover 6 to finally reach the pot.

[0045] like Fig.11As shown, the pot brush 7 is composed of a brush handle and a brush head. The brush head is connected to the lower end of the brush handle, and handles are extended from both ends of the brush head. The length of the brush handle at each end is slightly smaller than the radius of the pot.

[0046] This solution makes it more convenient to add seasoning, while greatly saving costs and increasing the stability and dust-proof effect of the device.

[0047] like Fig. 9 As shown, two sections of heating iron rings are added in the heating pot 5. After power is turned on, the electrical energy will be converted into thermal energy. One section is powered on for low-power heating, and two sections are powered on for high-power heating.

[0048] The temperature controller 8 is connected to the outer iron ring at the bottom of the heating pot 5. When the temperature is lower than the critical value, the iron ring is powered on and starts heating. When the temperature is higher than the rated value, the iron ring is powered off and stops heating.

[0049] Water is added at regular intervals by using a pump 3, and a weighing device 9 is placed under the heating pot 5. When the weight exceeds the rated value, water addition is stopped to keep the water content in a constant range to prevent overflow and drying.

[0050] like Fig.10 As shown, the water level alarm 11 is composed of a water level monitor 12 and a buzzer 13. The water level monitor 12 is attached to the water tank 10 to measure the water level of the water tank 10; the buzzer 13 is installed outside the front of the water level alarm 11 to make the sound more clear. When the sensor detects liquid / object, it outputs a low-level signal; when it detects that there is no liquid / object left, it outputs a high-level signal until the full liquid level / object is in place and the low-level output is restored. When the liquid level is too low, the buzzer will sound to remind you to add water.

[0051] The model of the temperature controller 8 used in this embodiment is XH-W1209, which can sense the temperature in the pot and turn on the power to heat the pot when the pot temperature is lower than the set minimum value, and cut off the power to stop heating when the pot temperature is higher than the set maximum value.

[0052] The weighing device 9 is of the brand WAAAX and is fixed to the bottom of the heating pot 5. It can monitor the weight of the food added to the pot and is used to control the soup so that it does not overflow.

[0053] The water level alarm 11 is composed of a water level monitor 12 and a buzzer 13. The model of the water level monitor 12 is ZCT-YOF07, which is installed on the water storage tank 10. When the water level of the water storage box is too low, the buzzer starts to warn, and the buzzer can be controlled by a manual switch.

[0054] The model of stepper motor 2 is 42 stepper motor, and the model of DC motor 1 is JGY370 DC reduction motor.

[0055] When the intelligent cooking robot is powered on, the temperature control module will work as a hot pot. Put the ingredients into the pot manually and adjust the position of the baffle in the seasoning box. Then set the rated weight of the weight monitoring module. Then we start the equipment, and the intelligent cooking robot will start the heating, timed seasoning, and stirring functions. During the working process, the pump will add water at regular intervals. If the weight exceeds the rated value, it will stop adding water. This method keeps the water content in a constant range to prevent overflow and drying. If the water level is too low, the buzzer will sound, and you need to add water to the water tank so that the water level monitor can detect water again. When the work is completed, the temperature control module will start a warming function again to prevent the food from cooling.

[0056] By controlling the rotation of the stepper motor screw and adjusting the position of the baffle, the seasoning can be precisely controlled. The pot lid and pot are located directly below the seasoning box, and the seasoning is added to the pot through the small hole on the pot lid. Liquid seasoning and pure water need to be manually added to two water tanks. They are extracted by a pump and finally added to the pot through the small hole on the pot lid. The order of adding seasonings can be automatically controlled according to the cooking order of the ingredients. The addition of solid seasonings is achieved through delay control and stepper motors, while the addition of liquid seasonings is also achieved through delay control and a small pump. In order to ensure that the seasoning can be added to the pot smoothly, a small hole is set on the pot lid under each seasoning box and small pump, and a surrounding slope is designed. This ensures that the seasoning can be fully added to the pot while maintaining the heat preservation of the pot lid. This design ensures that seasonings and liquid seasonings can be accurately and timely added to the pot of the cooking robot, thereby achieving precise cooking of ingredients.

[0057] The seasoning box can be replaced with a square box without a cover, that is, an ordinary small empty box. The lead screw of the stepper motor is connected to any side of the box. Figure 6 As shown, it can hold a meal's worth of seasonings as well as relatively small dishes. In order to adapt to the use of the square box, we will adjust the program of the stepper motor and change the box's rotation from one circle to half a circle (the dishes have a certain stickiness after washing and processing. Rotating half a circle can completely downwards the opening of the box, and the dishes and seasonings can better get rid of the stickiness under the action of gravity and fall into the pot).

[0058] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
