Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The invention is further illustrated by the following figures and examples.
Example one
Fig. 1 is a schematic structural view of a water heater according to a first embodiment of the present invention. Firstly, a tap water flow path is introduced, and as shown in fig. 1, tap water flows in from a water inlet connector 12 of a water heater through a water flow detection unit 9, passes through a heat exchanger 5, enters a venturi device 3, and is divided into two paths: one path flows out through the water outlet joint 13; the other path flows into the inner container 2 through the suction end and the valve of the Venturi device. With regard to this path of flow into the tank, due to the particularity of the venturi device, when the water heater supplies water to the outside, a negative pressure is generated on this path to the tank, so as to suck the hot water in the tank; when the water heater does not supply water to the outside, tap water fills the inner container 2 through the channel, the valve is driven by the motor 8 to fill the inner container, and the water level of the inner container reaches a set value by controlling the switch of the channel.
According to the operation principle of the water heater, when a user opens the water using terminal to use hot water, tap water flows in from the water inlet connector 12 of the water heater and flows through the water flow detection unit 9, and the water flow detection unit sends a signal to the central processing unit to control the heater 4 to work. At the moment, the venturi device generates negative pressure at the suction end so as to suck hot water in the inner container, tap water preheated by the heater is mixed with the hot water in the inner container, and the motor 8 controls the opening of the valve so as to control the water suction amount and realize the constant temperature effect; when the temperature of inlet water is high, and the temperature can be reached by instant heating, the motor control valve acts to close the channel leading to the inner container and gradually open the bypass channel, as shown in fig. 2, namely the 3c and 3d water channels are used for increasing the water quantity, because one end of the nozzle 3a is provided with a fine hole, the water quantity is limited to be very small (when the inner container channel is opened, a certain part of water in the inner container can be sucked to increase the water quantity, and when the channel is closed, the water quantity is reduced), the motor can control the 3c and 3d water channels to enable the flow quantity to be at a reasonable value, and meanwhile, the constant temperature can be realized; when the water channels 3c and 3d are opened to the maximum water yield and the water temperature exceeds a set value, the constant temperature is realized by adjusting the power of the heater 4. It is generally considered that the 3c, 3d and 3f waterways are isolated because once connected, the negative pressure created by the venturi device may be broken, resulting in either a failure to draw water from the bladder or a reduction in suction. Of course, the 3c and 3d water channels can also be made into 3a and 3b forms, which is equivalent to that two venturi devices are connected in parallel, and the 3c and 3d water channels can be communicated with the 3f at the moment (but experiments show that the effect of connecting two venturi structures in parallel is not ideal on the product).
When the water flow switch 9 senses that water flows through, the pump 7 is not operated (of course, if efficiency is not considered, the function description does not limit the protection scope of the patent); when the water flow switch 9 senses that no water flow passes through and detects that the water level in the inner container does not reach a set value, the valve control device (driven by the motor 8 to act) is opened to fill water into the inner container 2, and meanwhile, the heater 4 works. In order to enable the water heater to rapidly provide hot water with proper temperature, when water is added into the inner container, the motor 8 can control the opening of the valve to limit the rectification speed of water flow, so that tap water enters the inner container after being heated to a certain temperature by the heater, for example, the tap water is heated to 60 ℃, and therefore, in the water filling process, a user can immediately use the water, and the hot water can be used. If the inner container needs to reach higher water temperature, the water flow can be further reduced, and when the water filling is stopped, the hot water in the inner container is circulated to the heater shell 6 through the pump 7 to be heated for the second time so as to gradually increase the temperature. When the water temperature of the inner container is reduced due to heat dissipation and needs to be heated, the water can be circularly heated only through the pump 7.
Because the inner container is not mixed with cold water in the using process, the temperature of the water heater is more constant in the using process than that of the traditional constant-temperature water heater. And the water heater adopts a lower water outlet mode, so that hot water in the liner can be used up, and the 100% hot water output rate is achieved. Meanwhile, the energy of the water heater for pumping the hot water in the inner container comes from cold water, and the cold water and the hot water are mixed in the Venturi device, so that scalding accidents can not happen like the traditional water heater. The water heater can also adopt various control modes: 1. the capacity of the inner container is adjustable; 2. the capacity of the inner container is adjustable in stages; 3. rapidly heating water; 4. heating immediately; 5. air is mixed in. The control modes are described below respectively, the capacity of the liner is adjustable 1, the position of the water level can be continuously detected by adopting a water level sensing mode like that in fig. 1, and a user can set the water level according to the requirement by matching with a valve control device, for example, when people are few, various water quantities such as a half liner and an 1/3 liner can be selected, so that the heat loss can be reduced, and the heating speed is greatly accelerated. 2. The inner bag capacity is stage-wise adjustable, can select the water level of different time quantum inner bags different, bathe for example the user evening, then the inner bag is full of water when evening, and daytime because tap is with less hot water, can keep warm with the low water level to reduce the heat and scatter and disappear, the energy saving. 3. The scheme is characterized in that when the hot water is used up, the water heater does not fill the inner container with hot water at a time and then slowly heat the water, but controls the water adding speed to enable the cold water to reach the corresponding temperature and then enter the inner container, so that when the water of the water heater is used up, the hot water can be immediately available for next use, and the scheme does not need to wait for half an hour or even one hour. 4. When the instant heating mode is adopted, water is not added into the liner, when water is still stored in the liner, the water in the liner is used up, then the water path to the liner is closed by the motor 8, and the water heater is equivalent to an instant heating water heater. 5, mix in the air, this function can consider to adopt a bypass pipe, and one end intercommunication atmosphere, the other end is connected at venturi device's suction end or on its water route with the inner bag intercommunication, when the hot water in the water heater suction inner bag, also can mix a certain amount of air simultaneously for aquatic oxygen content is big, and the body feels the water yield also bigger, and the broken shock wave effect of bubble is favorable to wasing still. Or the bypass pipe is not needed, and when the liner of the instant heating mode is anhydrous, the valve leading to the liner is opened, so that air can be sucked.
In fig. 1, the water level sensing unit is a pressure level sensor capable of continuously measuring the level of the water. The water level is different, and the pressure water level sensor 10 determines the water level in the liner by measuring the pressure. The pressure sensor is very accurate in measurement, like some miniature electronic scales, the price is very cheap, but the measurement accuracy reaches 0.1 g, if the water pressure is applied to a silicon diaphragm, the area of the diaphragm is more than 5 square centimeters, the water level is increased by at least 5 g when the water level is increased by one centimeter, the water level is changed by one millimeter, the pressure is changed by 0.5 g, and the measurement accuracy can be accurately measured according to the accuracy of 0.1 g. The larger the diaphragm, the higher its accuracy. If the precision requirement is not high, the water level can be measured by the displacement generated by the hydraulic pressure pressing diaphragm, a contact can be driven by the displacement and is in contact with a conductive film or a coil of the adjustable resistor, and the water level can be continuously measured by the continuous change of the resistance value; this way, it is also possible to test the water level discontinuously by means of metal fingers or hall elements which are isolated from one another. The sensor is not shown in detail, and is a simple mature technology, and the sensor is not only simple to realize but also has a plurality of ways as long as the direction is determined.
Referring to the technical introduction of the fresh water-activating scheme, as shown in figure 1, the bottom of an inner container 2 is made into an inclined plane, a water suction port of a Venturi device is positioned at the lowest point of the inner container, the circulating water flow of a pump is generally more than 6L per minute, a spray head of the pump is arranged to flush the bottom of the inner container, so that dirt flows to the lowest point of the inner container and is sucked out by the water suction port of the Venturi device, and the inner container is always kept clean. If in case of large silt, the silt falls into the drain pipe 15, a valve can be arranged at the end of the drain pipe, so that periodic drainage and decontamination are facilitated. Simultaneously, because the hot water of inner bag is emptied every day even regularly, what be equivalent to every turn to use all is running water, does not always mix old water, thousand boiling water and incrustation scale and lead to aquatic microorganism to exceed standard like traditional water storage formula, the sanitary problem of water storage formula water heater has been solved to this patent.
The heating unit in fig. 1 is an electric heating tube, and may be in the form of another heater, as long as it can heat the water flowing through the heat exchanger 5 and the heater shell 6 at the same time. For example, an electromagnetic heater may be used, and even the heat exchanger 5 itself may be used to heat water by generating heat in a magnetic field.
The general scheme of the manufacturing process of the water heater is shown in fig. 1 and fig. 2 only as a schematic diagram for facilitating understanding, main parts are spread out as much as possible and are not overlapped so as to facilitate understanding and viewing, the actual structure is compact as much as possible, and meanwhile, the details of the known technology in the industry such as a temperature sensor, a control circuit board and the like are also omitted in the drawings. The liner of this patent can be formed by blow molding of PP, and its bottom is designed with an opening for the parts of the device that must be connected to the liner 2, such as various pipe joints and water level sensing devices. The water level sensing of inner bag can adopt various forms such as forced induction, tongue tube switch, hall switch, resistance induction, electric capacity response, radar response, infrared induction, and the more economic scheme is tongue tube sensing and hall response, and the essence of these two kinds of modes all is the magnetic induction, can adorn inductive switch at the top of inner bag. In order to continuously sense the water level, the pressure sensing of fig. 1 may be employed. The pipe needed to be connected to the inner container has three, two pump circulation connections, one being the drain pipe 15. The motor 8 and valve are assembled to the venturi device 3 to form an assembly, or they may be made as separate components that are assembled together, depending on the mold and assembly process. The water outlet connector 13 of the water heater can also be directly integrated on the venturi device 3, because in the actual product, the 90-degree bend angle as shown in the figure may not be needed, but is straight, so the mould can be manufactured into a whole, even if the bend is an elbow, the mould can be formed only by using a slide. The heater 4, the heat exchanger 5, the heater shell 6, and some necessary temperature sensors and temperature tripping switches (bimetal mechanical type, dry heating prevention) are assembled together to form a heating unit. The water inlet connector 12 of the water heater can be a part of the water flow detection unit 9, and the moving part of the water flow sensing unit can be blocked by silt, so that the water flow sensing unit is assembled in a straight pipe of the water inlet connector under the ordinary condition, and is convenient to detach and clean (the water flow detection unit generally adopts a Hall water flow switch). The inner container 2 is firstly installed in the shell 1, the components are sequentially installed in the shell, the connectors are connected, the circuit board is installed, the circuit is connected, and the water heater can enter a testing link. In the technology, the drain pipe 15 has a larger function, and is not only used for emptying the liner, and a filter screen is added on a bypass leading to the Venturi device, so that the Venturi device can be prevented from being blocked by massive scale, massive scale or silt can be deposited in the drain pipe, the function is equivalent to that of a human cecum, but the function is better than that of the cecum, and a valve can be arranged at the tail end of the drain pipe to discharge emptied impurities regularly.
Example two
As shown in fig. 3, this solution only changes the first heating unit into a double heat exchange tube, and the water level sensor only senses the highest water level, and cannot continuously detect the height of the water level (of course, the water level detection method of the first embodiment may also be adopted). The heating unit of the scheme generally considers that a double-water-flow-channel cast aluminum heater and an electromagnetic heater are adopted, and the heater cannot be damaged even if no water exists, so that the lowest water level protection can be omitted. Since the embodiment is the same except for the heater, it is not described much.
EXAMPLE III
Fig. 4 is a schematic diagram of the third embodiment, and as shown in the figure, two sets of heating units are adopted, and the heaters are arranged at the water outlet end of the venturi device, and the steel cup heater 14 is adopted as the external heater, because the venturi device is sensitive to the resistance of the water outlet end, when the heating unit is placed at the water outlet end, the heater with larger flow cross section area is preferably adopted, and of course, if a cast aluminum heater or other heaters are adopted, the operation is completely possible, only the corresponding water quantity is smaller, and the relative adjustable range of the proportion of cold water and hot water is smaller. Two groups of heating units are utilized, wherein the first heating unit is a steel cup heater 14 which mainly has the functions of secondary heating and instant heating; and the second heating unit 11 is arranged in the inner container 2 and heats the water stored in the inner container. This way, the pump in the first two embodiments is not needed to circulate the water in the inner container, and it can prevent the scale from forming on the first heating unit 11 due to high heating temperature, but the space is large, so the effect is not great, and the second heating unit 11 can also adopt the coating to prevent the scale from adhering. The water flow switch is mounted at the water outlet of the venturi device to prevent misjudgment of water flow, for example, when water is added into the inner container, tap water does not pass through the steel cup heater 14, if the water flow switch is mounted on the water inlet joint 12, dry burning will occur because the heating basis of the steel cup heater is a signal depending on the water flow switch, and of course, if the steel cup heater is mounted at the water inlet of the venturi device, the water flow switch can be mounted on the water inlet joint 12. The scheme has the defects that the bottom of the inner container cannot be flushed by water inlet and pump circulating water, and scale cannot be well removed. The working mode of the scheme is as follows: when the water heater is started, whether water flow passes through is detected, and if the water flow does not pass through, the steel cup heater 14 does not work; if water flows through the constant-temperature water heater, the second heating unit 11 does not work, the steel cup heater 14 works, the motor 8 adjusts the water suction amount of the inner container to achieve the constant-temperature effect, and if the water outlet temperature of the water in the inner container does not exceed a set value, the constant temperature is achieved by adjusting the power of the steel cup heater 14. When no water flows through the water heater, the water level and the water temperature of the inner container are detected by the water heater, and if the water level is higher than the lowest water level and the water temperature is lower than a set value, the heating unit II 11 is started to heat the water temperature of the inner container to a preset temperature; if the water level is lower than the lowest set value, the water is filled to the lowest water level first and then heated. This scheme has still adopted dual water level sensor, and pressure sensor 10 detects the water level in the inner bag 2 in succession, and floater water level sensor 16 is as the protection of second low water level, prevents that two 11 dry combustion methods of unit that generate heat from. The scheme is the same as the first embodiment except that two sets of heaters are provided and no pump is provided, and the description is omitted.
The above examples are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and all combinations and subcombinations of the various aspects of the invention are contemplated as falling within the scope of the invention.
