DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] Example 1

[0032] like Figures 1 to 6As shown, a steam generator described in the utility model includes a main water tank 1, a secondary water tank 2 and a control system. The main water tank 1 and the secondary water tank 2 are connected through a pipeline assembly 3. The main water tank 1 is provided with a temperature control mechanism 1a and a pressure control mechanism, and the secondary water tank 2 is provided with a water level control mechanism 2a. The control system is electrically connected with the temperature control mechanism 1a, the pressure control mechanism and the water level control mechanism 2a. The temperature control mechanism 1a is used to control the steam temperature in the main water tank 1, the pressure control mechanism is used to control the steam pressure in the main water tank 1, and the water level control mechanism 2a is used to control the water level depth in the main water tank 1 and the secondary water tank 2. The secondary water tank 2 is provided with a water inlet 2b, and the main water tank 1 is provided with a steam outlet 1c. The main water tank 1 ensures that the steam temperature is stable within a set range through the temperature control mechanism 1a, usually reaching about 120 degrees. The main water tank 1 ensures that the steam pressure is maintained at an appropriate level through the pressure control mechanism to meet the needs of steaming buns. The auxiliary water tank 2 is connected to the main water tank 1 through the pipe assembly 3, which plays the role of auxiliary water supply. A water level control machine is provided in the auxiliary water tank 2 to realize the precise control of the water level depth in the main water tank 1 and the auxiliary water tank 2. The water source is supplemented through the auxiliary water tank 2 to ensure that the steam generator can work continuously and stably. As the hub of the entire steam generator, the control system is electrically connected to the temperature control mechanism 1a, the pressure control mechanism and the water level control mechanism 2a. Through the control system, the user can easily set and adjust various parameters of the steam generator, such as steam temperature, steam pressure and water level depth. The auxiliary water tank 2 is provided with a water inlet 2b for replenishing the water source; the main water tank 1 is provided with a steam outlet 1c for outputting stable steam. The entire steam generator has a compact structure and is easy to operate. It can meet the high requirements for steam quality and stability in the process of steaming buns, and improve the quality and production efficiency of buns.

[0033] Specifically, refer to Figure 3 As shown, the pipe assembly 3 includes a first connecting pipe 3a and a second connecting pipe 3b, one end of the first connecting pipe 3a is connected to the top of the main water tank 1, the other end of the first connecting pipe 3a is connected to the top of the auxiliary water tank 2, one end of the second connecting pipe 3b is connected to the bottom of the main water tank 1, and the other end of the second connecting pipe 3b is connected to the bottom of the auxiliary water tank 2.

[0034] The utility model allows the steam between the main water tank 1 and the auxiliary water tank 2 to flow freely through the first connecting pipe 3a, ensuring uniform distribution of steam between the main water tank 1 and the auxiliary water tank 2. The water level between the main water tank 1 and the auxiliary water tank 2 can be kept balanced through the second connecting pipe 3b, and can effectively prevent the steam flow from being blocked due to the water level difference.

[0035] Specifically, refer to Figure 4As shown, the temperature control mechanism 1a includes a heating component 1a1 and a temperature detection component 1a2, both of which are electrically connected to the control system. The heating component 1a1 is used to heat the water in the main water tank 1 to generate steam, and the temperature detection component 1a2 is used to detect the steam temperature in the main water tank 1. The heating component 1a1 heats the water in the main water tank 1 to generate steam through the command of the control system. The temperature detection detects the steam temperature in the main water tank 1 and transmits the data to the control system. The control system compares the received temperature data with the preset temperature value, and then adjusts the working state of the heating component 1a1 to maintain the steam temperature within the set range.

[0036] The heating component 1a1 is an electric heating pipe. As an efficient and stable heating element, the electric heating pipe can quickly and evenly heat the water in the main water tank 1 to generate steam. The electric heating pipe is electrically connected to the control system and works by receiving instructions from the control system. The control system can adjust the working power of the electric heating pipe according to the actual required steam temperature, thereby realizing accurate control of the steam temperature. The temperature detection component 1a2 is a steam temperature sensor. The steam temperature sensor is a sensor specially designed for measuring steam temperature, with high sensitivity and high accuracy. It can sense the temperature change of the steam in the main water tank 1 in real time, and transmit these temperature data to the control system accurately and quickly. After receiving the temperature data, the control system will compare it with the preset temperature value. If the steam temperature is lower than the set value, the control system will instruct the heating component 1a1 to increase the power and increase the heating speed; conversely, if the steam temperature is higher than the set value, the control system will reduce the power of the heating component 1a1 to avoid excessive steam temperature. In this way, the control system can realize accurate control of the steam temperature and ensure that the steam temperature is always maintained within an appropriate range.

[0037] Specifically, refer to Figure 5 As shown, the pressure control mechanism includes a pressure relief component 1b1 and a pressure detection component 1b2, both of which are electrically connected to the control system. The pressure relief component 1b1 is used to discharge the steam pressure in the main water tank 1, and the pressure detection component 1b2 is used to detect the steam pressure in the main water tank 1. When the steam pressure reaches the preset upper limit, the pressure detection component 1b2 will immediately transmit this information to the control system. After receiving the pressure data, the control system will respond quickly. If the steam pressure is too high, the control system will instruct the pressure relief component 1b1 to work, which can quickly and effectively discharge the excess steam in the main water tank 1, thereby reducing the steam pressure and preventing safety problems caused by excessive pressure.

[0038] At the same time, the control system will also adjust the working state of the heating component 1a1 according to the data provided by the pressure detection component 1b2. If the steam pressure is too low, the control system will appropriately increase the power of the heating component 1a1 and increase the amount of steam generated to increase the steam pressure; conversely, if the steam pressure is moderate, the control system will keep the heating component 1a1 working stably to maintain a constant steam pressure.

[0039] Specifically, refer to Figure 5 As shown, the pressure relief assembly 1b1 includes a pressure relief port 1d and a pressure relief valve 1b11. The pressure relief port 1d is arranged in the main water tank 1 and communicates with the outside, and the pressure relief valve 1b11 is arranged in the pressure relief port 1d. When the steam pressure reaches or exceeds the set safety threshold, the pressure relief valve 1b11 will automatically open, and the excess steam can be quickly discharged through this pressure relief port 1d to avoid the potential danger caused by excessive pressure. Once the steam pressure drops to a safe range, the pressure relief valve 1b11 will automatically close to prevent further loss of steam.

[0040] Specifically, refer to Figure 5 As shown, the pressure detection component 1b2 is a steam pressure sensor. The steam pressure sensor is used to monitor the steam pressure changes in the main water tank 1 in real time, convert it into an electrical signal, and transmit it to the control system. After receiving these pressure data, the control system will compare it with the preset safety pressure range. If the steam pressure exceeds the preset safety upper limit, the control system will immediately trigger the corresponding action, such as starting the pressure relief component 1b1, and releasing excess steam by opening the pressure relief valve 1b11, thereby quickly reducing the steam pressure to prevent safety problems caused by excessive pressure. At the same time, the control system will also adjust the working state of the heating component 1a1 according to the data of the steam pressure sensor. If the steam pressure is too low, the control system will appropriately increase the power of the heating component 1a1 and increase the amount of steam generated to increase the steam pressure; conversely, if the steam pressure is moderate, the control system will keep the heating component 1a1 stable to maintain the constant steam pressure. Through the precise measurement of the steam pressure sensor and the intelligent adjustment of the control system, the steam generator can achieve precise control of the steam pressure and ensure a stable supply of steam during the steaming process. This design not only improves the efficiency and quality of steamed buns, but also enhances the safety and reliability of the steam generator, reduces the failure rate and extends the service life of the equipment.

[0041] Specifically, refer to Figure 6As shown, the water level control mechanism 2a includes a water level probe 2a1 and an electric control ball valve 2a2, both of which are electrically connected to the control system, the water level probe 2a1 is arranged in the auxiliary water tank 2, and the electric control ball valve 2a2 is arranged at the water inlet 2b. The water level probe 2a1 is used to monitor the water level changes in the auxiliary water tank 2 in real time. The water level probe 2a1 has high sensitivity and high precision, can accurately sense the height of the water level, and transmit this information to the control system in real time. When the control system receives the water level information from the water level probe 2a1, it will make a judgment based on the preset water level threshold. If the water level in the auxiliary water tank 2 is too low, the control system will immediately issue an instruction to open the electric control ball valve 2a2, allowing the water source to enter the auxiliary water tank 2 to replenish the water volume and ensure the continuous operation of the steam generator. On the contrary, if the water level reaches or exceeds the safety upper limit, the control system will instruct the electric control ball valve 2a2 to close to prevent further inflow of water source, avoid overflow of the auxiliary water tank 2 or other safety problems. Through the cooperation between the water level probe 2a1 and the electric ball valve 2a2, the water level control mechanism 2a can realize the precise control of the water level in the auxiliary water tank 2, ensuring that the steam generator always maintains a suitable water level during the process of steaming buns, and neither the steam generation is affected by the water level being too low, nor the potential safety hazards are caused by the water level being too high. In addition, the coordinated work of the water level control mechanism 2a, the temperature control mechanism 1a and the pressure control mechanism enables the steam generator to realize intelligent and automated management in multiple dimensions. By precisely controlling the temperature, pressure and water level of the steam, the steam generator can output stable, high-quality steam, providing a reliable heat source for steaming buns.

[0042] Specifically, refer to Figure 5 As shown, a drain port 1h is provided at the bottom of the main water tank 1, and a drain valve is provided in the drain port 1h, and the drain valve is electrically connected to the control system. The water in the main water tank 1 can be easily drained through the drain port 1h, especially when the main water tank 1 is cleaned or the water quality needs to be changed. A drain valve is provided in the drain port 1h, and the function of this drain valve is to control the flow of water, ensure that the water can be quickly and effectively drained when drainage is required, and can be tightly closed when drainage is not required to prevent water leakage. The drain valve is electrically connected to the control system, which means that the opening and closing of the drain valve can be controlled by the control system. Through the control system, the user can conveniently control the opening and closing of the drain valve, thereby realizing the discharge control of the water in the main water tank 1. This design not only improves the convenience of operation, but also enhances the safety and reliability of the use of the main water tank 1. For example, when rapid drainage is required, the user can quickly open the drain valve through the control system, avoiding the inconvenience and delay that may be caused by manual operation. At the same time, through the precise control of the control system, water leakage caused by misoperation or drainage valve failure can also be effectively prevented.

[0043] Specifically, refer to Figure 7 and Figure 8 As shown, the main water tank 1 is provided with an opening 1e at the top, and a box door 1f is provided at the opening 1e. The main water tank 1 and the box door 1f are connected by a hinge. An opening 1e is designed at the top of the main water tank 1. The main purpose of this opening 1e is to facilitate the cleaning of the inside of the water tank. When the water in the main water tank 1 is heated, scale is likely to be generated due to the water quality and the chemical reaction during the heating process. If these scales are not cleaned in time, they will not only affect the use effect of the water tank, but also may have an adverse effect on the water quality. Therefore, by designing an opening 1e, it is convenient for users to clean the inside of the water tank regularly, thereby ensuring the normal operation of the water tank and the cleanliness of the water quality. A box door 1f is provided at the opening 1e. The main function of this box door 1f is to close the opening 1e to ensure the sealing and safety of the water tank during normal use. When the water tank needs to be cleaned, the user can open the box door 1f and enter the inside of the water tank through the opening 1e for cleaning. After the cleaning is completed, the box door 1f is closed to restore the water tank to its sealed state. The main water tank 1 and the box door 1f are connected by hinges. A hinge is a component that allows two objects (here, the main water tank 1 and the door 1f) to maintain a rotatable connection. Through the connection of the hinge, the door 1f can be easily opened and closed, and can maintain a stable open and closed state without shaking or falling off at will. This design not only facilitates the use of the user, but also ensures the safety and stability of the water tank. For details, refer to Figure 7 and Figure 8 As shown, a handle 1g is provided on the outer side of the door 1f of the main water tank 1. The setting of the handle 1g makes it more convenient and labor-saving for the user to open or close the door 1f. By holding the handle 1g and applying appropriate force, the user can easily rotate the door 1f to open or close it. The design of the door 1f with a handle 1g is more humane and reduces the difficulty and inconvenience of user operation.

[0044] The operation of the electronic components in the steam generator is comprehensively controlled by the control circuit board 101. The control circuit board is provided with a power indicator light 102, a main switch SB, an audible and visual alarm 103, a pressure sensing switch 106, a heating switch KM1, a water replenishment switch KM2, a heating indicator light 104 and a water replenishment indicator light 105. The heating component 1a1 is powered by three-phase electricity. The heating component 1a1 is controlled by the heating switch KM1 and the pressure sensing switch 106. The electric control ball valve 2a2 is controlled by the water replenishment switch KM2. The water level probe 2a1 is electrically connected to the control circuit board, and the casing is grounded.

[0045] Example 2

[0046] In one possible embodiment, reference Figure 7 and Figure 8As shown, the main water tank 1 is provided with an opening 1e at the top, and a box door 1f is provided at the opening 1e. The main water tank 1 is connected to the box door 1f by a hinge, and a sealing rubber ring is provided at the connection between the box door 1f and the main water tank 1 to prevent leakage of high-pressure steam, and a lock is provided to lock the main water tank 1 and the box door 1f together. After locking, the main water tank 1 and the box door 1f can be fixed together and withstand the rated high pressure in the box. An opening 1e is designed at the top of the main water tank 1. The main purpose of this opening 1e is to facilitate the cleaning of the inside of the water tank. When the water in the main water tank 1 is heated, scale is likely to be generated due to the water quality and the chemical reaction during the heating process. If these scales are not cleaned in time, they will not only affect the use effect of the water tank, but also may have an adverse effect on the water quality. Therefore, by designing an opening 1e, it is convenient for users to clean the inside of the water tank regularly, thereby ensuring the normal operation of the water tank and the cleanliness of the water quality. A box door 1f is provided at the opening 1e. The main function of this door 1f is to close the opening 1e to ensure the sealing and safety of the water tank during normal use. When the water tank needs to be cleaned, the user can open the door 1f and enter the water tank through the opening 1e to perform cleaning operations. After the cleaning is completed, close the door 1f to restore the water tank to its sealed state. The main water tank 1 and the door 1f are connected by a hinge. A hinge is a component that enables a rotatable connection between two objects (here the main water tank 1 and the door 1f). Through the connection of the hinge, the door 1f can be easily opened and closed, and can maintain a stable open and closed state without shaking or falling off at will. This design not only facilitates user use, but also ensures the safety and stability of the water tank. For details, refer to Figure 7 and Figure 8 As shown, a handle 1g is provided on the outer side of the door 1f of the main water tank 1. The setting of the handle 1g makes it more convenient and labor-saving for the user to open or close the door 1f. By holding the handle 1g and applying appropriate force, the user can easily rotate the door 1f to open or close it. The design of the door 1f with a handle 1g is more humane and reduces the difficulty and inconvenience of user operation.
