Technical Field

[0002] An electric steam generator is a device that uses electricity as a heat source to convert water into steam by heating. It is usually composed of key components such as heating elements, water tanks, steam outlets, and control systems. Electric steam generators have the advantages of easy operation, small footprint, no pollution, and high thermal efficiency. They are widely used in food processing, medical disinfection, chemical industry, printing and dyeing and other fields.

[0003] In an electric heating steam generator, the external water tank plays a vital role. As the water source of the steam generator, it is responsible for storing and supplying an appropriate amount of water to the steam generator. The design of the external water tank allows users to easily monitor and control the water volume, ensuring that the performance and efficiency of the steam generator will not be affected by insufficient or excessive water during operation. However, with the long-term use of the external water tank, its inner wall tends to gradually accumulate scale formed by the crystallization of minerals in the water (such as calcium, magnesium, etc.) at high temperatures, as well as other impurities including suspended matter, microorganisms and their metabolites.

[0004] The accumulation of these scales and impurities poses multiple hazards to electric steam generators: they not only cover the heating elements, hindering the effective transfer of heat, thereby reducing heating efficiency and increasing energy consumption; they also increase the burden on the water tank and heating elements, accelerate the wear and aging process of the equipment, and shorten the service life of the equipment; at the same time, the impurities may contain microorganisms and chemicals that are harmful to the human body, and long-term accumulation will seriously affect the quality and safety of steam; in addition, regular cleaning of these scales and impurities in the external water tank requires a lot of manpower and material resources, thereby increasing the maintenance cost of the equipment. Therefore, for the external water tank of the electric steam generator, effective treatment measures must be taken to remove and prevent the accumulation of scale and impurities.

[0010] The above technical solution is adopted. In this solution, a scale cleaning plate is slidably connected to the inner cavity of the external water tank. When the water in the inner cavity of the external water tank is used up, when there is no buoyancy support of the water, the scale cleaning plate will move downward in the inner cavity of the external water tank.

Since the bottom wall is set at an angle, the impurities will be driven toward the connecting groove under the flushing of water.

[0018] The above-mentioned technical solution is adopted. In this solution, the upper end of the scale cleaning plate is fixedly connected to the lower end of the connecting rod. When the scale cleaning plate is affected by the buoyancy of water, it will drive the scale cleaning plate to slide upward in the inner cavity of the external water tank, and then drive the connecting rod to slide upward. Then, when the top of the connecting rod contacts the top wall of the inner cavity of the storage tube three, it can slide upward in the storage tube three. Then, when the top of the storage tube three contacts the top wall of the inner cavity of the storage tube two, it will drive the storage tube two to slide upward. Then, similarly, it will drive the storage tube one and the block to slide upward in turn. Finally, it will drive the block to move from the inner cavity of the connecting block two to the inner cavity of the flow control bin, thereby closing the inner cavity of the flow control bin and preventing water from being transported from the inner cavity of the connecting tube through the inner cavity of the flow control bin to the inner cavity of the delivery tube two, thereby controlling the amount of water.

The filter can be used to filter the extracted water, which can reduce impurities in the water and avoid impurities being transported into the heating pipe along with the water. The impurity content inside the device can be reduced. Long-term use will cause the mesh holes on the filter to be blocked. When the mesh holes on the filter are blocked, the staff can replace the filter to avoid affecting the normal use of the device.

[0022] The above technical solution is adopted. In this solution, a one-way valve is fixedly connected to the side of the inner cavity of the second delivery pipe close to the external water tank, so that the one-way valve can be used to prevent the water in the inner cavity of the external water tank from flowing back into the inner cavity of the second delivery pipe.

[0023] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0024] 1. The utility model provides an electric heating steam generator with convenient water volume control. A scale cleaning plate is slidably connected to the inner cavity of the external water tank. When the water in the inner cavity of the external water tank is used up, without the buoyancy support of the water, the scale cleaning plate will move downward in the inner cavity of the external water tank. Then, in the process of sliding downward, the inner wall of the external water tank is cleaned, thereby cleaning impurities attached to the inner wall of the external water tank, preventing these impurities from being attached to the inner wall of the external water tank for a long time, thereby forming scale, and then affecting the normal use of the device. By connecting the upper end of the scale cleaning plate with the water volume control The lower part of the control component is fixedly connected, so that when water is transported to the inner cavity of the external water tank, the buoyancy of the water will drive the scale cleaning plate to move upward, and then drive the water volume control component to slide upward, and then, it can drive the upper part of the water volume control component to slide from the inner cavity of the connecting block 2 to the inner cavity of the flow control bin. As the upper part of the water volume control component moves in the inner cavity of the flow control bin, it can reduce the flow of water in the inner cavity of the flow control bin to the inner cavity of the external water tank, thereby facilitating control, and even forming a closure for the inner cavity of the flow control bin, thereby facilitating control of water volume, thereby improving the practicality and universality of the device.

After the scale cleaning plate cleans the impurities attached to the inner wall of the external water tank, these impurities will fall on the bottom wall. Since the bottom wall is arranged at an angle, the impurities will be driven to flow toward the connecting groove under the flushing of water. The inner cavity of the sedimentation box is connected with the inner cavity of the connecting groove, so that the impurities transported to the inner cavity of the connecting groove will fall into the inner cavity of the sedimentation box, and then these impurities will settle to the bottom wall of the inner cavity of the sedimentation box, so that these impurities can be collected by the sedimentation box, and then it is convenient for the staff to deal with them later.

[0040] The present invention is further described in detail below with reference to the embodiments:

[0041] Example 1

[0042] like Figures 1-6As shown, the utility model provides an electric heating steam generator for conveniently controlling the amount of water, including an electric heating steam generator body 1, an external water tank 2 and a water pump 4. One side of the outer surface of the electric heating steam generator body 1 is fixedly connected to the external water tank 2, and a scale cleaning plate 21 is slidably connected to the inner cavity of the external water tank 2. A conveying component 6 is provided on one side of the external water tank 2. The conveying component 6 is used to control the amount of water entering the inner cavity of the external water tank 2. The conveying component 6 includes a conveying pipe 61 and a flow control bin 63. The upper part of the conveying pipe 61 is fixedly connected to the flow control bin 63. The side of the flow control bin 63 away from the conveying pipe 61 is fixedly connected to a connecting pipe 62. The middle part of the flow control bin 63 is fixedly connected to a connecting pipe. Block 2 64, a water volume sensor 66 is provided on the side of the flow control bin 63 close to the delivery pipe 2 61, and the water volume sensor 66 is used to monitor the water level in the inner cavity of the flow control bin 63. The inner cavity of the connecting block 2 64 is slidably connected with a water volume control component 65, and the lower part of the water volume control component 65 is fixedly connected to the upper end of the scale cleaning plate 21. The lower part of the inner cavity of the external water tank 2 is fixedly connected to the bottom wall 24. The side of the external water tank 2 close to the water pump 4 is fixedly connected to the delivery pipe 1 3, and the side of the delivery pipe 1 3 away from the external water tank 2 is fixedly connected to the input end of the water pump 4. The output end of the water pump 4 is fixedly connected to the water pipe 5, and the output end of the water pipe 5 is fixedly connected to the input end of the heating pipe in the inner cavity of the electric heating steam generator body 1.

[0043] In this embodiment, water can be heated by the electric heating steam generator body 1 to generate steam, and the water can be stored in the external water tank 2. The water in the inner cavity of the external water tank 2 can be extracted by the cooperation of the water pump 4 and the delivery pipe 3, and the water can be delivered to the heating pipe in the inner cavity of the electric heating steam generator body 1 by the cooperation of the water pump 4 and the water pipe 5. A scale cleaning plate 21 is slidably connected to the inner cavity of the external water tank 2. When the water in the inner cavity of the external water tank 2 is used up, the scale cleaning plate 21 will move downward in the inner cavity of the external water tank 2 when there is no buoyancy support of the water. In the process of sliding downward, the inner wall of the external water tank 2 is cleaned, thereby cleaning impurities attached to the inner wall of the external water tank 2, preventing these impurities from adhering to the inner wall of the external water tank 2 for a long time, thereby forming scale, and then affecting the normal use of the device. The upper end of the scale cleaning plate 21 is fixedly connected to the lower part of the water quantity control component 65, so that when the water in the inner cavity of the external water tank 2 is used up, the scale cleaning plate 21 will move downward in the inner cavity of the external water tank 2 when there is no buoyancy support of the water. When water is transported in the middle, under the action of the buoyancy of the water, the scale cleaning plate 21 will be driven to move upward, and then the water volume control component 65 will be driven to slide upward, and then the upper part of the water volume control component 65 can be driven to slide from the inner cavity of the connecting block 2 64 to the inner cavity of the flow control chamber 63. As the upper part of the water volume control component 65 moves in the inner cavity of the flow control chamber 63, the flow rate of the water in the inner cavity of the flow control chamber 63 to the inner cavity of the external water tank 2 can be reduced, thereby facilitating control, and even the inner cavity of the flow control chamber 63 can be closed, thereby facilitating water volume control. One end of the connecting pipe 62 is connected to the external water inlet pipe, so that the external water can be transported to the inner cavity of the connecting pipe 62. The water volume sensor 66 can monitor the water level of the inner cavity of the flow control chamber 63 near the side of the delivery pipe 2 61. When the water level of the inner cavity of the flow control chamber 63 near the side of the delivery pipe 2 61 is too low, the monitoring data will be transmitted to the data center, and then the controller will control the amount of water transported from the external water inlet pipe to the inner cavity of the connecting pipe 62.

[0044] Example 2

[0045] like Figure 7 、 Figure 8 and Figure 12 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the water volume control component 65 includes a block 651, the block 651 is slidably connected to the inner cavity of the connecting block 2 64, the inner cavity of the block 651 is slidably connected to the storage tube 1 652, the inner cavity of the storage tube 1 652 is slidably connected to the storage tube 2 653, the inner cavity of the storage tube 2 653 is slidably connected to the storage tube 3 654, the inner cavity of the storage tube 3 654 is slidably connected to the connecting rod 655, the lower end of the connecting rod 655 is fixedly connected to the upper end of the scale cleaning plate 21, the inner cavity of the delivery pipe 2 61 is communicated with the inner cavity of the external water tank 2, and the inner cavity of the delivery pipe 2 61 close to the external water tank 2 is fixedly connected to a one-way valve 611.

[0046] In this embodiment, when it is necessary to transport water from the outside to the heating tube in the inner cavity of the electric heating steam generator body 1, first, the controller controls the water inlet pipe to transport water to the inner cavity of the connecting pipe 62, and then the connecting pipe 62 will transport the water to the inner cavity of the flow control chamber 63, and then the water transported to the inner cavity of the flow control chamber 63 will pass through the water volume sensor 66 and flow to the inner cavity of the delivery pipe 2 61, and then the water in the inner cavity of the delivery pipe 2 61 will flow into the inner cavity of the external water tank 2 through the one-way valve 611, and then gather in the inner cavity of the external water tank 2. Under the buoyancy of the water in the inner cavity of the external water tank 2, the scale cleaning plate 21 will be driven to slide upward in the inner cavity of the external water tank 2, and then it will bring The movable connecting rod 655 slides upward, and then when the top of the connecting rod 655 contacts the top wall of the inner cavity of the storage tube three 654, it can slide upward in the storage tube three 654, and then when the top of the storage tube three 654 contacts the top wall of the inner cavity of the storage tube two 653, it will drive the storage tube two 653 to slide upward, and then similarly, drive the storage tube one 652 and the block 651 to slide upward in turn, and finally, drive the block 651 to move from the inner cavity of the connecting block two 64 to the inner cavity of the flow control chamber 63, so that the inner cavity of the flow control chamber 63 can be closed, preventing water from being transported from the inner cavity of the connecting tube 62 through the inner cavity of the flow control chamber 63 to the inner cavity of the delivery tube two 61, thereby controlling the amount of water.

[0049] In this embodiment, when the water volume sensor 66 does not sense water passing through, or the water volume becomes smaller, the monitoring data will be transmitted to the CNC center, and then the controller will control the flow rate of water transported from the water inlet pipe to the inner cavity of the connecting pipe 62. At the same time, the water pump 4 will be operated through the controller, and then the water pump 4 and the delivery pipe 3 will be used to extract the water in the inner cavity of the external water tank 2. During the extraction process, the water can be filtered through the filter 31, and then the filtered water can be transported to the heating pipe in the inner cavity of the electric heating steam generator body 1 through the cooperation of the water pump 4 and the water pipe 5, so that the water can be heated by the electric heating steam generator body 1 to generate steam.

[0050] Example 4

[0051] like Figure 9 and Figure 10As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the scale cleaning plate 21 is symmetrically provided with a slide groove 211, and the inner cavity of the external water tank 2 close to the slide groove 211 is fixedly connected with a guide rail block 23, and the outer surface of the guide rail block 23 on the same side is slidingly connected to the inner cavity of the slide groove 211, and a connecting groove 241 is provided on one side of the bottom wall 24, and the bottom wall 24 is inclined. The horizontal height of the side of the bottom wall 24 away from the connecting groove 241 is higher than the horizontal height of the side of the bottom wall 24 close to the connecting groove 241, and the lower end of the bottom wall 24 is symmetrically fixedly connected to the side of the connecting groove 241 with a connecting block 25, and the opposite surfaces of the two connecting blocks 25 are slidably connected with a sedimentation box 26, and the inner cavity of the sedimentation box 26 is communicated with the inner cavity of the connecting groove 241.

[0052] In this embodiment, when the device stops running, the water in the inner cavity of the external water tank 2 is pumped out, and then the buoyancy of the water is lost, the scale cleaning plate 21 will slide downward under the action of its own gravity, and be slidably connected with the guide block 23 through the slide groove 211, so that the movement trajectory of the scale cleaning plate 21 can be limited, and then in the process of sliding, the inner wall of the external water tank 2 is cleaned, and impurities attached to the inner wall of the external water tank 2 can be scraped off, and then these impurities will fall on the bottom wall 24, and then when the device is running next time, the scale cleaning plate 21 will be fed to the external water tank 2 through the delivery pipe 261. Water is transported into the inner cavity of the box 2, and then the water will flush the impurities that fall on the bottom wall 24 toward the connecting groove 241, and then these impurities will flow into the inner cavity of the connecting groove 241 together with the water, and then these impurities will be precipitated in the inner cavity of the sedimentation box 26. After the device stops running, the sedimentation box 26 will be slid out from the connecting block 25, and then these impurities will be processed, so as to reduce the content of impurities in the inner cavity of the external water tank 2, reduce or even avoid long-term use, these impurities will form scale, and then affect the use of the device.

[0053] The working principle of the electric heating steam generator which is convenient for controlling the water amount is described in detail below.

[0054] like Figures 1-12As shown, when it is necessary to transport water from the outside to the heating tube in the inner cavity of the electric heating steam generator body 1, first, the controller controls the water inlet pipe to transport water to the inner cavity of the connecting pipe 62, and then the connecting pipe 62 will transport the water to the inner cavity of the flow control chamber 63, and then the water transported to the inner cavity of the flow control chamber 63 will pass through the water volume sensor 66 and flow to the inner cavity of the delivery pipe 2 61, and then the water in the inner cavity of the delivery pipe 2 61 will flow into the inner cavity of the external water tank 2 through the one-way valve 611, and then gather in the inner cavity of the external water tank 2, and under the buoyancy of the water in the inner cavity of the external water tank 2, the scale cleaning plate 21 will be driven to slide upward in the inner cavity of the external water tank 2, and then the connecting pipe 62 ... The connecting rod 655 slides upward, and then when the top of the connecting rod 655 contacts the top wall of the inner cavity of the third storage tube 654, it can slide upward in the third storage tube 654. Then, when the top of the third storage tube 654 contacts the top wall of the inner cavity of the second storage tube 653, it will drive the second storage tube 653 to slide upward. Then, similarly, it will drive the first storage tube 652 and the stopper 651 to slide upward in turn. Finally, it drives the stopper 651 to move from the inner cavity of the second connecting block 64 to the inner cavity of the flow control chamber 63, thereby sealing the inner cavity of the flow control chamber 63 and preventing water from being transported from the inner cavity of the connecting tube 62 through the inner cavity of the flow control chamber 63 to the inner cavity of the second delivery tube 61, thereby controlling the water volume.

[0055] When the water volume sensor 66 does not sense water passing through, or the water volume becomes small, the monitored data will be transmitted to the numerical control center, and then the controller will control the flow rate of water delivered from the water inlet pipe to the inner cavity of the connecting pipe 62. At the same time, the water pump 4 will be operated through the controller, and then the water pump 4 and the delivery pipe 3 will cooperate to extract the water in the inner cavity of the external water tank 2. During the extraction process, the water can be filtered through the filter 31, and then the filtered water can be delivered to the heating pipe in the inner cavity of the electric steam generator body 1 through the cooperation of the water pump 4 and the water pipe 5, so that the water can be heated by the electric steam generator body 1 to generate steam;

[0056] When the device stops running, the water in the inner cavity of the external water tank 2 is pumped out, and then the buoyancy of the water is lost. The scale cleaning plate 21 will slide downward under the action of its own gravity, and be slidably connected with the guide block 23 through the slide groove 211, so that the movement trajectory of the scale cleaning plate 21 can be limited. Then, during the sliding process, the inner wall of the external water tank 2 is cleaned, and impurities attached to the inner wall of the external water tank 2 can be scraped off. Then, these impurities will fall on the bottom wall 24, and then the next time the device is running, they will be transported to the external water tank 2 through the delivery pipe 261. Water is transported into the cavity, and then the water will flush the impurities that fall on the bottom wall 24 toward the connecting groove 241, and then these impurities will flow into the inner cavity of the connecting groove 241 together with the water, and then these impurities will be precipitated in the inner cavity of the sedimentation box 26. After the device stops running, the sedimentation box 26 will be slid out from the connecting block 25, and then these impurities will be processed, so as to reduce the content of impurities in the inner cavity of the external water tank 2, reduce or even avoid long-term use, these impurities will form scale, and then affect the use of the device.
