Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically a noodle maker. Background Technology
[0002] Traditional instant noodles or noodle cooking mainly relies on manual operation. Users need to manually boil water, control the water temperature and time, put the noodles into boiling water to cook, and then add seasonings according to personal taste. Existing technologies have developed a variety of automated or semi-automated instant noodle cooking equipment, which are mainly used in home settings, convenience stores, fast food restaurants, airports and other places. Their core functions usually include automatic heating, quantitative water injection, timed noodle cooking, and automatic ingredient feeding.
[0003] Most currently used noodle cookers have sensors installed inside the water tank, which are constantly submerged in water. Over time, scale easily accumulates on the sensor surface, affecting the sensitivity and accuracy of water level detection. This can lead to inaccurate water level readings and disrupt normal equipment operation. Furthermore, the design of directly installing electric heating rods inside the water tank also results in significant scale buildup over time, impacting heating efficiency and increasing maintenance difficulty. Additionally, the difficulty in flexibly adjusting the height of the heating rods and the internal space of the water tank during installation makes subsequent maintenance challenging. Therefore, design optimization is urgently needed to improve the maintainability and user experience of the equipment. Utility Model Content
[0004] The purpose of this invention is to provide a noodle maker to solve the problems mentioned in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a noodle maker, comprising a shell, a water tank, a water pump, a main control board, and a threaded rod. An induction cooker module is connected to the outside of the shell, and a control panel is detachably connected to one side of the shell via a snap-fit structure. A water inlet pipe is provided through one side of the shell. The main control board is located inside the shell, and a water level sensing component is provided on the outside of the water tank for sensing the water level at different heights within the tank.
[0006] As a preferred technical solution, the water level sensing component is a non-contact water level sensor installed on one side of the sensing water tank. It can monitor the process of liquid overflowing from the water tank into the return water pipe. The non-contact water level sensor is tightly wrapped around the outer surface of the return water pipe, senses the change in the liquid level inside the water tank, and transmits the real-time detection signal to the control panel. After receiving the signal, the control panel synchronously executes the start and stop control operation of the water pump.
[0007] The water level sensing component is a non-contact water level sensor II installed on the outside of the return water pipe. The non-contact water level sensor II is based on the photoelectric sensor detection principle to monitor the water level inside the water tank in a non-contact manner. The photoelectric sensor detects the water level based on the principle of light reflection and refraction and transmits the detection signal to the control panel. After receiving the signal, the control panel immediately triggers the start and stop control operation of the water pump.
[0008] As a preferred technical solution, the second non-contact water level sensor is electrically connected to the main control board. The temperature sensor is installed at the top of the water tank. A drain valve is connected through one side of the water tank. The water pump is installed inside the housing. An exhaust pipe is connected through the top of the water tank. The water tank is installed inside the housing. The water tank is connected to the output end of the water pump through an inlet pipe at the bottom. Another set of inlet pipes is connected to the input end of the water pump. The second non-contact water level sensor and the water pump are electrically connected through the main control board on the same side. The main control board is used to receive the detection signal from the second non-contact water level sensor or the first non-contact water level sensor.
[0009] As a preferred technical solution, the water tank is equipped with a lifting mechanism inside. The lifting mechanism is connected to one side of the U-shaped frame via a threaded rod. When the threaded rod rotates, it drives the U-shaped frame to move vertically, thereby causing the electric heating rod to move up and down synchronously inside the water tank. This facilitates cleaning or maintenance of the electric heating rod. The lifting mechanism includes a water outlet pipe, an electric heating rod, a U-shaped frame, a threaded rod, a guide rod, and a solenoid valve. The water outlet pipe is connected to a housing, and the water tank is located inside the housing. The U-shaped frame is located inside the water tank, and the electric heating rod is connected to the outer side of the U-shaped frame. The threaded rod is connected to the other side of the U-shaped frame, and a guide rod is connected to one side of the U-shaped frame. The top of the guide rod is connected to the water tank, and the solenoid valve is located on one side of the water tank.
[0010] As a preferred technical solution, the electric heating rod forms a nut transmission pair with the threaded rod through a U-shaped frame fixedly connected to the outside, and the U-shaped frame cooperates with the threaded rod as a nut component.
[0011] As a preferred technical solution, one end of the water outlet pipe is connected to the other side of the water tank via a solenoid valve, which is used to control the on / off state between the water outlet pipe and the water tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The measuring mechanism of this utility model uses different types of water level sensors, namely, water level sensor 1 and water level sensor 2, to automatically adjust the water level in the columnar water tank, ensuring that the water level in the tank is maintained within a suitable range to meet the water demand for subsequent tasks such as cooking noodles. In addition, water level sensor 1 can also transmit the sensed water level signal to the control panel to assist in the precise control of the water pump's start and stop. Water level sensor 1 can also assist the control panel in further precise regulation of the water pump, enhancing the reliability and flexibility of water level control.
[0013] 2. This utility model achieves the lifting function of the electric heating rod through a lifting mechanism, which includes components such as a threaded rod, a U-shaped frame, and a guide rod. The electric heating rod is fixedly connected to the U-shaped frame on the outside and forms a nut transmission pair with the threaded rod, ensuring that the U-shaped frame and the electric heating rod move smoothly in the vertical direction and adjust the electric heating rod to a suitable height position, making it convenient for users to take it out of the water tank for cleaning or maintenance. This solves the problem of traditional electric heating rods being difficult to adjust and maintain during installation and fixing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figures 1 to 7 As shown, this utility model provides the following technical solution: a noodle maker, including a shell 1, a water tank 9, a water pump 10, a main control board 12, and a threaded rod 17. An induction cooker module 2 is connected to the outside of the shell 1. A control panel 3 is detachably connected to one side of the shell 1 through a snap-fit structure. A water inlet pipe 5 is provided through one side of the shell 1. The main control board 12 is located inside the shell 1. A water level sensing component 7 is provided outside the water tank 9. The water level sensing component 7 is used to sense the water level at different heights inside the water tank 9.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the water level sensing component 7 is a non-contact water level sensor 8 installed on one side of the sensing water tank 9. It can monitor the process of liquid overflowing from the water tank 9 into the return water pipe 21. The non-contact water level sensor 8 is tightly wrapped around the outer surface of the return water pipe 21, senses the change in the liquid level inside the water tank 9, and transmits the real-time detection signal to the control panel 3. After receiving the signal, the control panel 3 synchronously executes the start and stop control operation of the water pump 10. The water level sensing component 7 is also a non-contact water level sensor 19 installed on one side of the water tank 9. The non-contact water level sensor 19 is based on the photoelectric sensor detection principle and performs non-contact monitoring of the water level inside the water tank 9. The photoelectric sensor detects the water level based on the principle of light reflection and refraction and synchronously transmits the detection signal to the control panel 3. After receiving the signal, the control panel 3 immediately triggers the start and stop control operation of the water pump 10.
[0019] Among them, the drain valve 6 is located on one side of the water tank 9. When it is necessary to clean the water tank 9 or drain the water in the water tank 9, the drain valve 6 can be operated to open and drain the water in the water tank 9. The exhaust pipe 13 is connected through to the top of the water tank 9. During the water filling and heating process, it can balance the air pressure inside and outside the water tank 9 and ensure the stability of the air pressure inside the water tank 9.
[0020] Example 1: As Figure 6The return water pipe fitting 21 is wrapped with a non-contact water level sensor 8, and only the non-contact water level sensor 8 is installed inside the device. The return water pipe fitting 21 is a silicone hose. To monitor the liquid fluctuations inside the return water pipe fitting 21, heat shrink tubing is wrapped around the outer surface of the return water pipe fitting 21 near the interface of the water tank 9 to accommodate the deformation of the soft pipe. The non-contact water level sensor 8 collects the liquid status signal inside the return water pipe fitting 21 in real time and transmits it to the control panel 3. The control panel 3 combines the water level data of the water tank 9 with other auxiliary ranging methods or preset logic to indirectly obtain the water level and dynamically adjust the speed of the water pump 10. When the water level is lower than the low threshold, it replenishes water at full speed. When it approaches the high level, it gradually reduces the speed to reduce water hammer impact. The control panel 3 dynamically adjusts the speed of the water pump 10 based on the water level data of the non-contact water level sensor 19. If liquid appears in the return water pipe fitting 21, the non-contact water level sensor 18 detects an increase in capacitance. The control panel 3 reduces the power of the water pump 10 without stopping the machine. The user can manually check the problem.
[0021] Example 2: Figure 7 The water level sensing component 7 is a non-contact water level sensor 19 installed on the outside of the return water pipe 21. The non-contact water level sensor 19 is vertically fixed to the outer side wall of the water tank 9 at a distance from the top. Based on the photoelectric sensor detection principle, it accurately acquires real-time water level data and simultaneously transmits the detection signal to the control panel 3. The control panel 3 has a built-in water level threshold. When the water level data received from the non-contact water level sensor 19 is lower than the predetermined value, it immediately outputs a low-level signal to shut down the water pump 10. When the water level drops back to the predetermined value, the water pump 10 is triggered to start full speed to replenish water. After receiving the signal, the control panel 3 immediately triggers the start and stop control operation of the water pump 10. The non-contact water level sensor 19 transmits water level data to the control panel 3 in real time. When the water level is higher than the preset high level, the control panel 3 outputs a low-level signal to shut down the water pump 10.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the non-contact water level sensor 19 is electrically connected to the main control board 12. The temperature sensor 11 is installed at the top of the water tank 9. A drain valve 6 is connected through one side of the water tank 9. The water pump 10 is installed inside the outer casing 1. The exhaust pipe 13 is connected through the top of the water tank 9. The water tank 9 is installed inside the outer casing 1. The water tank 9 is connected to the output end of the water pump 10 through the water inlet pipe 5 set at the bottom. The input end of the water pump 10 is connected to another set of water inlet pipes 5. The non-contact water level sensor 19 and the water pump 10 are electrically connected through the main control board 12 set on the same side. The main control board 12 is used to receive the detection signal of the non-contact water level sensor 19 or the non-contact water level sensor 8. The water tank 9 is equipped with a lifting mechanism 14. The lifting mechanism 14 forms a threaded transmission engagement with one side of the U-shaped frame 16 through a threaded rod 17. When the threaded rod 17 rotates, it can drive the U-shaped frame 16 to move in the vertical direction, thereby driving the electric heating rod 15 in the water. The internal lifting mechanism 14 of the tank 9 is synchronously raised and lowered to facilitate cleaning or maintenance of the electric heating rod 15. The lifting mechanism 14 includes a water outlet pipe 4, an electric heating rod 15, a U-shaped frame 16, a threaded rod 17, a guide rod 18, and a solenoid valve 20. The water outlet pipe 4 is connected to the outer shell 1. A water tank 9 is installed inside the outer shell 1. The U-shaped frame 16 is installed inside the water tank 9. The electric heating rod 15 is connected to the outer side of the U-shaped frame 16. The threaded rod 17 is connected to the other side of the U-shaped frame 16. The guide rod 18 is connected to one side of the U-shaped frame 16. The top of the guide rod 18 is connected to the water tank 9. The solenoid valve 20 is located on one side of the water tank 9. The electric heating rod 15 forms a nut transmission pair with the threaded rod 17 through the U-shaped frame 16 fixedly connected to the outer side. The U-shaped frame 16 acts as a nut component and cooperates with the threaded rod 17. One end of the water outlet pipe 4 is connected to the other side of the water tank 9 through the solenoid valve 20. The solenoid valve 20 is used to control the on / off state between the water outlet pipe 4 and the water tank 9.
[0023] Among them, the temperature sensor 11 is installed on the top of the water tank 9 to monitor the temperature of the water in the water tank 9 in real time and transmit the temperature signal to the main control board 12. The main control board 12 can assist in controlling the heating power and other parameters of the induction cooker module 2 according to the temperature to ensure that the water temperature meets the requirements during the noodle cooking process.
[0024] The working principle of this utility model is as follows: When the instant noodle maker is running, the water level regulation function is mainly achieved through the coordinated operation of non-contact water level sensor 18, non-contact water level sensor 219, water pump 10, and main control board 12. Non-contact water level sensor 18 and non-contact water level sensor 219 are used to sense the water level at different heights within the water tank 9. Non-contact water level sensor 219 is electrically connected to the main control board 12, which is also electrically connected to the water pump 10. When the water level in the water tank 9 is lower than the low-level threshold set by non-contact water level sensor 219, non-contact water level sensor 219 will... The low water level detection signal is transmitted to the main control board 12. After analyzing and processing the signal, the main control board 12 controls the water pump 10 to start. The water pump 10 draws water from an external water source through the water inlet pipe 5 connected to the input end, and then injects water into the water tank 9 through the water inlet pipe 5 connected to the output end. As the water injection process proceeds, the water level in the water tank 9 gradually rises. When the water level rises to the high threshold set by the non-contact water level sensor 19, the non-contact water level sensor 19 transmits the high water level detection signal to the main control board 12. After analyzing the signal, the main control board 12 controls the water pump 10 to shut down and stop injecting water into the water tank 9. The U-shaped frame 16 acts as a nut component and cooperates with the threaded rod 17. A guide rod 18 is connected through one side of the U-shaped frame 16. The top of the guide rod 18 is connected to the water tank 9 and serves as a guide. When it is necessary to clean or repair the electric heating rod 15, the threaded rod 17 is driven to rotate. This can usually be achieved by a conventional drive component such as a rotating handle or motor located at an appropriate position outside the instant noodle machine. Due to the restriction of the guide rod 18, the U-shaped frame 16 can only move in a straight line along the guide rod 18. As the threaded rod 17 rotates, the U-shaped frame 16 moves in the vertical direction, thereby driving the electric heating rod 15, which is fixedly connected to it, to rise and fall synchronously inside the water tank 9. The connection between the water outlet pipe 4 and the water tank 9 is controlled by a solenoid valve 20. One end of the water outlet pipe 4 passes through the outer casing 1 and is connected to the water tank 9. The other end of the water outlet pipe 4 is connected to the water tank 9 by a solenoid valve 20. When water in the water tank 9 is needed, for example, when hot water needs to be supplied to the noodle cooking area during the cooking process, the main control board 12 controls the solenoid valve 20 to open according to relevant control instructions. At this time, the channel between the water outlet pipe 4 and the water tank 9 is opened, and the water in the water tank 9 flows out through the water outlet pipe 4 under its own gravity or water pressure, realizing the output of water flow. When water is not needed, the main control board 12 controls the solenoid valve 20 to close, cutting off the connection between the water outlet pipe 4 and the water tank 9, and stopping the water flow.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
