Description

Technical Field

[0001] The utility model belongs to the technical field of solar water heaters, and specifically relates to a solar water heater with automatic water level control. Background Art

[0002] With the continuous development of solar energy technology, solar water heaters have become the main way to supply hot water for many households. However, in the use of solar water heaters, the water level control in the water tank has always been a key issue. In order to achieve automatic control of the water level, a water level sensor is usually installed on the water heater tank to detect the water level and transmit the signal to the controller to control the water entry.

[0003] In real life, the water inside the solar water heater will be at high temperature for a long time, which makes it easy for impurities to form in the water. After a long period of accumulation, these impurities will form scale on the inner wall of the water tank and the water level sensor. The accumulation of scale will not only affect the service life of the water tank, but also affect the normal operation of the water level sensor, and even cause damage to the sensor.

[0004] The traditional solution is to regularly disassemble the water level sensor for cleaning or replacement, but this method is time-consuming and laborious. Therefore, a device that can automatically clean impurities and scale on the water level sensor is needed to increase the service life of the water level sensor and reduce maintenance costs.

[0005] To this end, we proposed a solar water heater with automatic water level control, which can increase the service life of the water level sensor and save time and effort without the need for disassembly. Utility Model Content

[0006] The purpose of the utility model is to provide a solar water heater with automatic water level control, which can prolong the service life of the water level sensor and achieve the effect of saving time and labor without disassembly.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A solar water heater with automatic water level control comprises a water heater tank, a water level sensor and a controller. A threaded hole is provided on the water heater tank, a mounting plate is provided inside the threaded hole, a first mounting hole and two second mounting holes are provided on the mounting plate, the water level sensor is installed inside the first mounting hole, the water level sensor is connected to the controller via a connecting wire, and a debris removal component for removing debris from the water level sensor is provided inside the second mounting hole.

[0009] The debris removal component includes a connecting rod movably arranged inside the two second mounting holes and a first movable disk and a second movable disk mounted on the water level sensor, the bottom of the connecting rod is connected to the first movable disk, the first movable disk is provided with a conical scraper mounted on the water level sensor, the top of the connecting rod passes through the second movable disk and is connected to a rotating disk, the connecting rod is provided with a spring located between the second movable disk and the mounting disk, and a debris removal brush corresponding to the water level sensor is provided on the outside of the connecting rod.

[0010] Furthermore, the mounting plate is provided with threads, and the threads are connected to the threaded holes.

[0011] Furthermore, the first movable disk and the conical scraper are both provided with a second through hole, and the diameter of the second through hole is larger than the diameter of the water level sensor.

[0012] Furthermore, a third through hole is formed on the second movable disk, and a diameter of the third through hole is larger than a diameter of the water level sensor.

[0013] Furthermore, the installation plate is provided with ventilation holes.

[0014] Furthermore, the first mounting hole matches the water level sensor.

[0015] The technical effects achieved by this utility model are:

[0016] First, connect the water level sensor to the controller, then install the water level sensor in the first installation hole, install the two connecting rods in the second installation hole, and then install the installation plate in the threaded hole. Figure 2 As shown, at this time the water level sensor is in Figure 2 When working, the water level of the water tank of the water heater is sensed by the water level sensor. When the water level is full, the water level sensor transmits the signal to the controller through the connecting wire. The controller controls the water to enter, so that the second movable disk moves up. When the second movable disk moves up, it drives the two connecting rods to move. When the two connecting rods move, they drive the first movable disk to move the conical scraper on the water level sensor, so as to scrape the scale. After scraping, there are still some tiny impurities attached to the water level sensor. At this time, you only need to rotate the rotating disk, and the rotating disk drives the connecting rod to rotate, so that the connecting rod drives the impurity removal brush to remove the tiny impurities on the water level sensor, thereby improving the cleaning effect. The device can increase the service life of the water level sensor, and at the same time, there is no need to disassemble it, so as to achieve the effect of saving time and effort.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-5 As shown, the technical solution adopted by the utility model is specifically as follows: a solar water heater with automatic water level control includes a water heater tank 1, a water level sensor 2 and a controller 3. A threaded hole 4 is opened on the water heater tank 1, a mounting plate 5 is arranged inside the threaded hole 4, a first mounting hole 6 and two second mounting holes 7 are arranged on the mounting plate 5, a water level sensor 2 is installed inside the first mounting hole 6, the water level sensor 2 is connected to the controller 3 through a connecting wire, and a de-impurity component for removing impurities from the water level sensor 2 is arranged inside the second mounting hole 7.

[0026] The debris removal component includes a connecting rod 8 movably arranged inside the two second mounting holes 7 and a first movable disk 9 and a second movable disk 10 sleeved on the water level sensor 2. The bottom of the connecting rod 8 is connected to the first movable disk 9, and the first movable disk 9 is provided with a conical scraper 14 sleeved on the water level sensor 2. The top of the connecting rod 8 passes through the second movable disk 10 and is connected to the rotating disk 11, and the connecting rod 8 is sleeved with a spring 12 located between the second movable disk 10 and the mounting disk 5, and a debris removal brush 13 corresponding to the water level sensor 2 is provided on the outside of the connecting rod 8.

[0027] Its working principle is: firstly, the water level sensor 2 is connected to the controller 3, then the water level sensor 2 is installed in the first installation hole 6, the two connecting rods 8 are installed in the second installation hole 7, and then the installation plate 5 is installed in the threaded hole 4. Figure 2 As shown, at this time, the water level sensor 2 is in Figure 2 The position of the solar water heater, when working, the water level of the water tank 1 is sensed by the water level sensor 2. When the water level is full, the water level sensor 2 transmits the signal to the controller 3 through the connecting wire, and the controller 3 controls the water entry. In real life, the water inside the solar water heater is always in a high temperature state, and there are many impurities in the water. After a long time, these impurities will form scale after being exposed to high temperature. These scales will not only adhere to the inner wall of the water tank, but also adhere to the water level sensor 2, thereby causing the water level sensor 2 to be damaged. For this reason, the utility model does not need to be replaced, and does not If it needs to be disassembled for cleaning, people only need to move the second movable disk 10 upwards, and when the second movable disk 10 moves upwards, it drives the two connecting rods 8 to move. When the two connecting rods 8 move, they drive the first movable disk 9 to move the conical scraper 14 on the water level sensor 2, so as to scrape off the scale. After scraping, there are still some tiny impurities attached to the water level sensor 2. At this time, it is only necessary to rotate the rotating disk 11, and the rotating disk 11 drives the connecting rod 8 to rotate, so that the connecting rod 8 drives the impurity removal brush 13 to remove the tiny impurities on the water level sensor 2, thereby improving the cleaning effect. The device can increase the service life of the water level sensor 2, and at the same time, it does not need to be disassembled, achieving the effect of saving time and effort.

[0028] Among them, the water heater tank 1 is provided with a water inlet pipe and a drain pipe, and the water inlet pipe is provided with a water pump. The water pump is connected to the controller 3 through a connecting wire. The water pump provides power to make water enter the water heater tank 1 from the water inlet pipe. When the water level sensor 2 senses that the water level is full, the water level sensor 2 transmits the signal to the controller 3 through the connecting wire. The controller 3 stops the water pump through the connecting wire, thereby achieving the effect of automatic control.

[0029] It should be noted that the controller 3 is a single-chip microcomputer, which is an integrated circuit chip that integrates multiple components such as a central processing unit (CPU), memory, and input / output interface on one chip. Single-chip microcomputers have the characteristics of small size, low cost, high reliability, easy programming and control, and are widely used in various electronic devices and embedded systems. The main function of a single-chip microcomputer is to execute programs, and various control and data processing tasks can be achieved through programming. It can collect sensor data, control the operation of external devices, perform data calculations and logical judgments, etc. Single-chip microcomputers usually have abundant input / output ports, which can be connected and communicated with various sensors, actuators, displays and other external devices.

[0030] There are many types of microcontrollers, and different manufacturers and series have their own characteristics and advantages. Common microcontroller manufacturers include ST (STMicroelectronics), Microchip, NXP, Atmel (acquired by Microchip), etc. Each manufacturer has launched a series of microcontroller products with different performance and functions to meet the needs of different applications.

[0031] The application fields of single-chip microcomputers are very wide, including household appliances, industrial control, automotive electronics, medical equipment, smart home, Internet of Things, etc. They play an important role in various automation systems, smart sensor nodes, remote controls, data acquisition equipment, etc.

[0032] The model of water level sensor 2 is a float sensor, which uses the principle of buoyancy. Usually there is a float that moves as the water level rises or falls. The position of the float is transmitted to the sensor mechanically or electronically to detect the change of water level. The working principle of the float sensor is based on the principle of buoyancy. It usually consists of a float and a sensor component.

[0033] A float is an object that floats on the surface of a liquid, usually made of a material less dense than water, such as plastic or foam. When the level of the liquid rises or falls, the float moves up and down as the liquid moves.

[0034] The sensor assembly is connected to the float and is able to detect the position or movement of the float. Common sensor types include mechanical switches, potentiometers, reed switches or other electronic sensors.

[0035] When the float rises, it triggers the sensor, generating a corresponding signal or switch action. This signal can be transmitted to a control system or other equipment to indicate the change in water level.

[0036] For example, in a simple float-type water level sensor, the float may actuate a mechanical switch that closes or opens when the float reaches a certain height, sending an electrical signal. Alternatively, the movement of the float may be transmitted to a potentiometer through a rod or pull wire, changing its resistance and generating an electrical signal related to the water level.

[0037] Water pump model Centrifugal pump, this is a common type of water pump, which uses centrifugal force to draw liquid into the pump and discharge it. Centrifugal pumps are suitable for conveying various liquids, including clean water.

[0038] It should be noted that the working principles of the water level sensor 2, the water pump and the controller 3 all belong to the prior art and will not be elaborated on here.

[0039] The mounting plate 5 is provided with threads, which are connected to the threaded holes 4. Such a configuration enables the mounting plate 5 to be threadedly installed, thereby achieving the effect of saving time and labor.

[0040] The first movable disk 9 and the conical scraper 14 are both provided with a second through hole 15, the diameter of which is larger than the diameter of the water level sensor 2. This arrangement enables the first movable disk 9 and the conical scraper 14 to move on the water level sensor 2. At the same time, when scraping off scale on the water level sensor 2, the water level sensor 2 will not be scraped, thereby preventing damage to the water level sensor 2.

[0041] The second movable disk 10 is provided with a third through hole 16 , the diameter of which is larger than the diameter of the water level sensor 2 , so that no interference will be caused when the second movable disk 10 drives the connecting rod 8 to move upward.

[0042] The mounting plate 5 is provided with air holes 17, through which a ventilation effect can be achieved. This arrangement enables water to enter parallel to the water level.

[0043] The first mounting hole 6 matches the water level sensor 2 , and matching here means that the water level sensor 2 can be installed and limited.

[0044] The working principle of the utility model is as follows: firstly, the water level sensor 2 is connected to the controller 3, then the water level sensor 2 is installed in the first installation hole 6, the two connecting rods 8 are installed in the second installation hole 7, and then the installation plate 5 is installed in the threaded hole 4. Figure 2 As shown, at this time, the water level sensor 2 is in Figure 2The position of the solar water heater, when working, the water level of the water tank 1 is sensed by the water level sensor 2. When the water level is full, the water level sensor 2 transmits the signal to the controller 3 through the connecting wire, and the controller 3 controls the water entry. In real life, the water inside the solar water heater is always in a high temperature state, and there are many impurities in the water. After a long time, these impurities will form scale after being exposed to high temperature. These scales will not only adhere to the inner wall of the water tank, but also adhere to the water level sensor 2, thereby causing the water level sensor 2 to be damaged. For this reason, the utility model does not need to be replaced, and does not If it needs to be disassembled for cleaning, people only need to move the second movable disk 10 upwards, and when the second movable disk 10 moves upwards, it drives the two connecting rods 8 to move. When the two connecting rods 8 move, they drive the first movable disk 9 to move the conical scraper 14 on the water level sensor 2, so as to scrape off the scale. After scraping, there are still some tiny impurities attached to the water level sensor 2. At this time, it is only necessary to rotate the rotating disk 11, and the rotating disk 11 drives the connecting rod 8 to rotate, so that the connecting rod 8 drives the impurity removal brush 13 to remove the tiny impurities on the water level sensor 2, thereby improving the cleaning effect. The device can increase the service life of the water level sensor 2, and at the same time, it does not need to be disassembled, achieving the effect of saving time and effort.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
