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 present invention will be further explained with reference to the drawings and examples.

Example one

Fig. 1 and 2 are schematic structural views of a water heater according to a first embodiment of the present invention, as shown in fig. 1, a heat exchanger 2 and a heater 3 are installed in a water tank 1, a crankshaft 5 passes through a hole on the water tank 1 and is installed on the water tank, and is sealed by a rubber ring, and a relative rotation motion can be performed between the crankshaft and the water tank. One end of the crankshaft 5 is matched with an output shaft of the motor 4, the other end of the crankshaft is matched with the heat exchanger, and a rotation degree of freedom and a translation degree of freedom along the direction of the heat exchanger are reserved instead of being fixedly matched with the heat exchanger, so that when the crankshaft 5 rotates, the crankshaft is converted into the swinging of the heat exchanger 2. When the motor 4 is electrified and rotated, the crankshaft is driven to rotate, and the crankshaft drives the heat exchanger 2 to swing, so that the convection velocity of the heat storage medium between the outer surface of the heat exchanger and the water tank 1 is increased, and the heat exchange efficiency is improved. Through practical tests, only a stainless steel corrugated pipe with the length of 4 meters needs to be wound into a spring shape, the cost is low, and the heat exchange temperature difference can reach 1-2 degrees. The difference between the heat exchanger in fig. 1 and fig. 2 is that the heat exchanger in fig. 2 adopts a double-head winding method, and the double-head winding method is good in that the heat exchanger is in the elastic deformation range of a spring when swinging, and the corrugated pipe is not easy to fatigue fracture. However, as in the winding method shown in fig. 1, after the spring is wound, a straight pipe needs to be bent and inverted, and the straight pipe is easy to fatigue fracture in the swinging process.

This water heater water tank only is used for storing the heat accumulation medium, need not bear running water pressure, only is used for storing the heat accumulation medium, and the inner bag as long as can bear the weight of heat accumulation medium can, can use the inner bag of plastic material, for example water tank 1 can adopt PP material blow molding. The inner container made of the plastic material is not only not corroded, but also lighter in weight, lower in cost, longer in service life and better in recycling. The heat exchanger 2 is formed by winding a stainless steel corrugated pipe, tap water flows through the corrugated pipe, and heat is transferred to water flowing through the heat exchanger through a heat storage medium in the water tank through a pipe wall. As shown in fig. 1 and 2, an upper mounting hole and a lower mounting hole are formed at one end of the water tank, threads are formed on the outer wall of the mounting holes, and the heat exchanger 2 and the heater 3 are screwed by a threaded cover after being inserted into the mounting holes. In actual products, the movable end of the heat exchanger is also provided with an end cover, the end cover is fixed with the movable end of the heat exchanger, an opening on the end cover is matched with the crankshaft, and the crankshaft is inserted into a hole on the end cover. The connection of the output shaft of the motor and the crankshaft can be realized through an intermediate part in the actual product design and manufacture, the crankshaft is generally made of metal materials and is not suitable for manufacturing complex shapes, the intermediate part is formed by plastic injection molding and is assembled on the inner container to play the dual functions of transmission and sealing, and two ends of the intermediate part are respectively matched with the crankshaft and the output shaft of the motor.

The working mode is as follows: when the temperature in the water tank 1 is lower than the set temperature, the heater 3 is electrified to work to heat the water to the set temperature; when the water flow switch senses that the heat exchanger 2 has water flow, the motor 4 is electrified to work, the crankshaft is driven to rotate, the crankshaft stirs one end of the heat exchanger 2 to swing, the heat exchange efficiency is improved, and the heat exchange temperature difference of 1-2 degrees can be basically achieved.

Example two

Fig. 3 is the structure schematic diagram of the second embodiment of the utility model, compares first embodiment and has increased the structure that gathers the storehouse, gathers the storehouse and comprises gathering storehouse shell 7, heater 3, second grade heat exchanger 6, valve aperture module 8, and the principle forms a environment of invariable high temperature relatively in a little space to play the purpose of stabilizing out water temperature and improving heat exchange efficiency, can also realize instant heating effect.

In the first embodiment, the experience of the water heater without using the thermostatic valve is difficult to guarantee unless the volume of the water tank is made large. This is because when the heat exchanger 2 absorbs the heat in the water tank 1, the temperature of the water tank 1 is continuously reduced, and the user needs to continuously adjust the mixing valve to maintain the temperature constant. The constant water temperature of the common water storage type water heater is due to the specific gravity problem of water, cold water sinks below, the cold water is pushed up from the bottom through the structural design, and hot water is discharged from the top, so that the constant temperature water discharging for a long time is ensured. Under the condition of heat exchange like the embodiment, the temperature in the liner is uniformly reduced, so that hot water discharged by heat exchange is uniformly reduced, and normal bathing can not be carried out without a thermostatic valve.

The structure of fig. 3 is designed for solving the problem that the temperature of the outlet water is unstable due to the continuous decrease of the temperature in the heat exchange technology, the energy collecting bin is equivalent to a temperature balancer, the temperature in the energy collecting bin can be always kept constant within a certain temperature range by adjusting the temperature parameter of the valve opening module 8, for example, the energy collecting bin can be always kept constant at 70 degrees, so that when the temperature of the liner is decreased from 70 degrees to 40 degrees, even to 30 degrees, the energy collecting bin can always keep 70 degrees (proved by experiments), tap water exchanges heat through the heat exchanger 2, although the tap water continuously decreases along with the temperature of the water tank, and then flows into the secondary heat exchanger 6 in the energy collecting bin through the heat exchanger connecting pipe 9 and then exchanges heat through the secondary, and the outlet water temperature is relatively constant due to the constant temperature in the energy collecting bin, so that the constant temperature effect similar to that the traditional electric water storage mode. Meanwhile, the structure can also realize an instant heating effect, when the temperature of inlet water is higher, the water in the water tank 1 does not need to be preheated for heat preservation, the heater 3 only heats a small amount of water in the energy-gathering bin shell 7, tap water flows through the water heater 2 firstly, because the water tank is at room temperature, the heat exchanger 2 does not absorb heat at the moment, the tap water flows into the secondary heat exchanger 6 through the heat exchanger connecting pipe 9, and the secondary heat exchanger 6 absorbs the heat of a heat storage medium in the energy-gathering bin to reach the use temperature. When the heat storage medium in the water tank 1 needs to be heated, the valve opening degree module 8 is opened when the temperature in the energy collecting bin reaches the limited temperature, so that water in the energy collecting bin shell can be convected with water in the water tank, and the heat storage medium in the water tank is heated.

EXAMPLE III

Fig. 4 is a schematic diagram of a third embodiment of the present patent, which is different from the first embodiment in that the heat exchanger 2 is divided into an upper part and a lower part, so as to make the best use of the heat in the inner container, and this structure has a requirement on the direction of water inlet and outlet of the heat exchanger, and tap water must first flow through the part of the heat exchanger 2 at the lower side of the water tank 1 and then flow out from the part at the upper side. Assuming that the water temperature in the water tank 1 is uniform at the beginning, tap water firstly passes through the lower heat exchanger group to absorb the heat of the lower half liner, and then the preheated tap water flows through the upper heat exchanger to absorb the heat of the upper half liner. Tap water flows through the lower heat exchanger because the temperature difference with the inner container is large, the heat absorption is large, and tap water after heat exchange flows into the upper heat exchanger because the temperature difference is small, the heat absorption is small, and finally when the temperature of the lower half inner container is close to the temperature of tap water, the upper half inner container has higher temperature, the tap water can be heated to the service temperature, so the service time is effectively prolonged.

Meanwhile, as for the structure shown in the figures 1, 2 and 4, one more heater can be added, the second heater is arranged on the upper part of the water tank, when the temperature of the inner container is lower than the certain temperature, the second heater works, and the heater 3 at the bottom of the water tank does not work, so that the service life can be effectively prolonged. Because if the heater 3 at the bottom of the water tank works, the water temperature of the whole inner container needs to be raised, and the second heater works to heat the water around the heat exchanger at the top, whether the temperature is rapidly raised can be judged, and even the instant heating effect can be achieved when the temperature of the inlet water is high.

Example four

Fig. 5 is a schematic diagram of a fourth embodiment of this patent, and this embodiment adopts the water pump to drive the water flow motion in the water tank 1 so as to enhance the heat exchange efficiency, as shown in the figure, the water suction port of the water pump 10 is connected with the water tank, and the water outlet of the water pump is connected with the spray pipe 12 through the water pump connecting pipe 11 (certainly, the water pump connecting pipe 11 may not be needed, if the structure permits, the water outlet of the water pump may be directly connected to the spray pipe by using a screw. When the temperature in the water tank is higher, the temperature of heat transfer play water can reach service temperature, and water pump 10 need not to start this moment, and when the water tank temperature reduced to can not reach service temperature through natural heat transfer, the water pump started, and one end absorbs water from the water tank, through the even spraying of spray tube on heat exchanger water heater surface to the convection velocity of water around the reinforcing heat exchanger, reinforcing heat transfer effect. The water spraying structure can be made into various forms, for example, the spraying mechanism can be made into a disc like a shower head, the heat exchanger is also coiled into a mosquito-repellent incense shape, and the spraying mechanism sprays water to the whole disc surface of the heat exchanger like the shower head. As for whether the spraying mechanism is required to be made into a form of uniformly spraying water, the heat exchange efficiency can be most effectively improved by making a uniform water spraying mode as long as the power of the water pump is large enough to enable the water around the whole heat exchanger 2 to flow rapidly and making the water into a large water spraying port directly.

The above examples are not intended to be exhaustive of all structures and methods, and combinations of all aspects described above, and any aspect which can be readily devised by the present invention, are within the scope of the invention.
