Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The inventor goes through intensive research and diligent attempts to break through the disadvantages of large volume and single appearance of the existing electric water heater. After years of arduous efforts, a brand-new phase-change water heater 100 is designed, and the phase-change water heater 100 fully utilizes the properties of phase-change materials in high-temperature heat storage and energy storage and low-temperature heat release, so that the requirement that a user wants to use water quickly is met.

Referring now to fig. 1-12, a phase change water heater 100 according to an embodiment of the present invention is described, the phase change water heater 100 including: the water path control system comprises a shell 10, an inner container 20, a heat exchanger 47 and a water path control system 40. The phase-change water heater 100 at least comprises a water discharging mode and a circulation heating mode

Specifically, as shown in fig. 1-2, the housing 10 defines a chamber 11, and the inner bladder 20 is disposed within the chamber 11. That is, the housing 10 provides an installation space, and the inner container 20 is installed in the chamber 11.

The inner container 20 is filled with a phase change material. The phase change material has heat absorption and heat release functions. The heat exchanger 47 is embedded in the phase change material. When there is a temperature difference between the phase change material and the water of the heat exchanger 47, the phase change material exchanges heat with the heat exchanger 47. That is, when the temperature of the water in the heat exchanger 47 is lower than that of the phase change material, the heat of the phase change material is released to the water in the heat exchanger 47, and the temperature of the water in the heat exchanger 47 rises rapidly; in case the temperature of the water in the heat exchanger 47 is higher than the phase change material, the phase change material will absorb the heat of the water in the heat exchanger 47, so that the temperature of the phase change material will rise continuously.

The waterway control system 40 is respectively connected with the water inlet 471 and the water outlet 472 of the heat exchanger 47. And the circulation heating mode and the water discharging mode are switched by the waterway control system 40. In the case of the water discharging mode, the heat exchanger 47 supplies hot water to the outside, the water path control system 40 supplements water to the water inlet 471 of the heat exchanger 47, and in the process, the heat of the phase change material is continuously transferred to the water in the heat exchanger 47, so that the continuous external delivery of hot water is realized; in the case of the circulation heating mode, the heat exchanger 47 does not deliver hot water to the outside, and the water flows circularly between the waterway control system 40 and the heat exchanger 47 after being heated by the waterway control system 40, and in the process, the phase-change material continuously absorbs the heat of the water in the heat exchanger 47 until the temperature of the phase-change material reaches the preset temperature.

That is, the water discharge capacity (i.e., the maximum water discharge amount) of the phase-change water heater 100 is positively correlated with the heat storage capacity of the phase-change material. The phase-change water heater 100 pre-stores heat in the phase-change material, and the phase-change material can rapidly release the heat to water in the heat exchanger 47 under the condition that hot water needs to be used, so that the purpose of rapidly discharging the hot water is achieved.

In addition, because the water in the heat exchanger 47 is continuously updated and replaced in the water discharging process of the phase change water heater 100, compared with the traditional water heater, the problem of using residual water does not exist, the problem of generating bacteria in the heat exchanger 47 is avoided, and healthy water can be provided for users.

Compare in traditional water heater, according to the utility model discloses phase change water heater 100 utilizes phase change material heat storage capacity, need not to heat repeatedly, just can realize going out hot water fast, has saved the energy consumption, has avoided inner bag 20 again by dirt and the pollution problem that long-term heating brought.

In some embodiments of the present invention, referring to fig. 3-5, the front surface of the casing 10 is provided with the panel assembly 12, that is, the panel assembly 12 is disposed in front of the casing 10 for covering the configuration of the surface of the casing 10, that is, the internal structure of the phase-change water heater 100 cannot be seen through the decoration of the panel assembly 12, so that the whole body is simple and elegant.

Wherein, panel assembly 12 sets up in the preceding of casing 10, and panel assembly 12 includes: a connecting plate 122 and a glass plate 121, the glass plate 121 being glued to the connecting plate 122. By providing a panel assembly 12 at the front of the housing 10, the panel assembly 12 may, on the one hand, reinforce the structural strength of the housing assembly and, on the other hand, may also mask the configuration of the surface of the housing 10. According to the utility model discloses phase change water heater 100 through set up a panel assembly 12 in the front of casing 10, and it is complicated to have solved phase change water heater 100's shell subassembly structure, the loaded down with trivial details problem of assembly process.

Furthermore, the volume of the phase change material expands with the increase of the temperature, and the volume of the inner container 20 changes with the decrease of the temperature, particularly, in the case that the glass plate 121 is provided on the housing 10, the glass plate 121 is easily broken by the pressing.

The inventor has noted the above problems in the design process, and has made an innovative improvement to the structure of the shell 10 of the phase-change water heater 100 in order to avoid the deformation of the inner container 20 pressing against the glass plate 121.

Specifically, as shown in fig. 6 and 7, the housing 10 includes a front case 13 and a rear case 14 connected to each other, a glass plate 121 and a connecting plate 122 are disposed at the front of the front case 13, the glass plate 121 is disposed on the connecting plate 122, the connecting plate 122 is connected to the front case 13, and a gap structure 15 is disposed between the rear surface of the connecting plate 122 and the front surface of the front case 13. The gap structure 15 may allow a partial gap, i.e., at least a portion of the gap may be separated, between the front housing 13 and the connecting plate 122.

In other words, the rear surface of the connecting plate 122 is not in contact with at least a portion of the front surface of the front housing 13, so that the force of the expansion of the inner container 20 acting on the front housing 13 is not completely transmitted to the connecting plate 122, thereby reducing the influence of the expansion of the inner container 20 on the glass plate 121 to a certain extent and preventing the glass plate 121 from being deformed by the expansion force.

Here, the forming position of the gap structure 15 is not particularly limited, and the gap structure 15 may be formed on the connecting plate 122, or the gap structure 15 may be formed on the front case 13, or the gap structure 15 may be formed on both the connecting plate 122 and the front case 13. Therefore, according to the utility model discloses casing 10 subassembly is through clearance structure 15 between the rear surface with connecting plate 122 and the front surface of preceding shell 13 to reduce the influence of inner bag 20 bulging force to glass board 121, guaranteed glass board 121's planarization, prevent its deformation.

That is, the rear surface of the connection plate 122 is separated from the front surface of the front case 13 by a convex hull, wherein the larger the protruding height of the convex hull with respect to the rear surface of the connection plate 122, the larger the gap between the connection plate 122 and the front case 13.

Further alternatively, the convex hull is concavely formed from the front side to the rear side of the connecting plate 122. I.e., the convex hull is stretched from front to back and the front surface of web 122 forms a dimple relative to the location of the convex hull. Wherein, a screw hole can be formed on the convex hull, and under the condition that the front shell 13 and the connecting plate 122 are locked by a screw, the screw can be hidden in the concave pit, thereby avoiding the extrusion of the glass plate 121 caused by the screw.

It can be understood that, because the glass plate 121 is disposed on the front surface of the housing 10 of the present application, the glass plate 121 is brittle and is easily damaged, that is, the deformation of the phase change material of the glass plate 121 is greatly influenced.

In order to reduce the influence of the phase change material on the glass plate 121, the reinforcing structure 16 is provided for resisting the force of the phase change material towards the glass plate 121, so that the pressure applied to the glass plate 121 is reduced, the influence of the phase change material on the glass plate 121 can be reduced, and the glass plate 121 is prevented from deforming.

The reinforcing structure 16 is provided on the outer wall of the inner container 20 and at least a portion of the reinforcing structure 16 is on the same side as the glass panel 121. At least a portion of the reinforcing structure 16 is located on the same side as the glass plate 121, in other words, at least a portion of the reinforcing structure 16 is located on a side wall of the inner container 20 close to the glass plate 121, and a portion of the reinforcing structure 16 may be located on the same side as the glass plate 121, or the entire reinforcing structure 16 may be located on the same side as the glass plate 121. The reinforcing structure 16 is disposed on the outer wall of the inner container 20, and plays a role of fastening the inner container 20, resisting the expansion force of the phase change material toward the glass plate 121, and protecting the glass plate 121.

In other words, the location of the reinforcing structure 16 in the present application is not exclusive, as long as the reinforcing structure 16 is capable of acting against the expansion force of the phase change material toward the glass sheet 121.

In other embodiments of the present invention, specifically, as shown in fig. 1-3 and 5, the housing 10 defines a chamber 11, at least one side wall of the housing 10 being provided with a port.

In other embodiments of the present invention, the phase change water heater 100 at least comprises a water discharging mode and a circulation heating mode, in the case of the water discharging mode, the cold water in the water inlet pipe 41 and the hot water flowing out from the heat exchanger 47 flow into the thermostatic valve 44 together to be mixed, and the cold water in the water inlet pipe 41 is also synchronously conveyed into the heat exchanger 47 to supplement the water amount, wherein the heater 45 may or may not preheat the cold water before the cold water enters the heat exchanger 47; in the case of the circulation heating mode, the water inlet pipe 41 and the water outlet pipe 42 are both closed, and water flows circularly between the heat exchanger 47 and the heater 45 under the pumping pressure of the water pump 46, cold water enters the heat exchanger 47, and the heater 45 must preheat the cold water to ensure that the phase change material can store heat sufficiently. The heating pipe can be a heat pipe, and the power of the heat pipe can be set to be adjustable, so that the heat pipe can be heated by adopting different heating powers in different working modes.

However under the limited prerequisite of phase transition water heater 100 spatial structure, for make waterway control system 40's pipeline and structure easy to assemble simultaneously, can guarantee superior performance again, be not the easy affairs condition of piece in the product development process, the utility model discloses the waterway control system 40 pipeline of solution phase transition water heater 100 is complicated, assembly operation difficulty, the problem of stable performance.

Referring now to fig. 7-9, a waterway control system 40 of a phase change water heater 100 according to an embodiment of the present invention is described, including: heat exchanger 47, inlet pipe 41 and outlet pipe 42.

Specifically, the heat exchanger 47 includes a water inlet 471 and a water outlet 472. The heat exchanger 47 is embedded in the phase change material of the phase change water heater 100, and when there is a temperature difference between the phase change material and the water of the heat exchanger 47, the phase change material exchanges heat with the heat exchanger 47. That is, in the case that the temperature of the water in the heat exchanger 47 is lower than that of the phase change material, the heat of the phase change material is released to the water in the heat exchanger 47; in the case where the temperature of the water in the heat exchanger 47 is higher than the phase change material, the phase change material will absorb heat from the water in the heat exchanger 47.

As shown in fig. 7 and fig. 8, the outlet of the water inlet pipe 41 is connected to the water inlet 471 and the water outlet 472 of the heat exchanger 47, respectively. It should be noted that, in the present application, "connected" should be understood in a broad sense, and may represent a direct connection or an indirect connection, where, due to the one-way valve 43 and the thermostatic valve 44 being arranged in parallel between the water inlet pipe 41 and the water outlet 472 of the heat exchanger 47, the water inlet pipe 41 and the water outlet 472 of the heat exchanger 47 are indirectly connected. Since the heater 45 is disposed between the water inlet 471 of the water inlet pipe 41 and the heat exchanger 47, the water inlet 471 of the water inlet pipe 41 and the heat exchanger 47 are also indirectly connected.

In the waterway control system 40, when the phase-change water heater 100 is in the water discharge mode, the water in the water inlet pipe 41 can be simultaneously led to the thermostatic valve 44 and the heat exchanger 47, so that the water is discharged from the water outlet pipe 42, the water is introduced into the water inlet pipe 41, and the phase-change water heater 100 can continuously discharge the water.

The water pump 46 is disposed between the water inlet 471 of the heat exchanger 47 and the water outlet 472 of the heat exchanger 47. In the case of the circulation heating mode, the water pump 46 drives the water flow between the inside and outside of the heat exchanger 47. It will be appreciated that in the case of the discharge mode, the water pump 46 may not be activated, and that the water pump 46 may only act as a water flow channel. Thus, the energy consumption of the phase-change water heater 100 may be reduced and the service life of the water pump 46 may be extended.

As shown in fig. 9, in the case of the circulation heating mode, the water inlet 471 and the water outlet 472 of the heat exchanger 47 are communicated through the pipeline in which the check valve 43 is located. In other words, in the heat release mode, the check valve 43 is hydraulically opened from the water inlet 471 and the water outlet 472 of the heat exchanger 47, so that cold water is prevented from reversely entering the heat exchanger 47 from the path of the check valve 43, and the normal flow of the waterway control system 40 is ensured.

In short, according to the embodiment of the present invention, in the water path control system 40 of the phase change water heater 100, the outlet of the water inlet pipe 41 is connected to the water inlet 471 and the water outlet 472 of the heat exchanger 47, and the check valve 43 and the thermostatic valve 44 are arranged between the water inlet pipe 41 and the water outlet 472 of the heat exchanger 47 in parallel, so that the pipeline layout of the water path control system 40 is simplified, and the circulation heating mode and the water discharging mode of the water path control system 40 are switched conveniently.

In an alternative embodiment, the water pump 46 is disposed between the water inlet 471 of the heat exchanger 47 and the outlet of the water inlet pipe 41. That is, the water pump 46 is disposed near the water inlet pipe 41, so that the water pump 46 can be filled with cold water in an inactive state (neither the circulation heating mode nor the water discharging mode) of the phase-change water heater 100, and thus, the water pump 46 can be prevented from being soaked with hot water for a long time, and the service life of the water pump 46 can be prolonged.

In other embodiments of the present invention, a heat insulating layer is disposed between the outer wall of the inner container 20 and the inner wall of the casing 10. The insulating layer can prevent heat of the inner container 20 from radiating to the outside, improve the heat insulating property of the phase-change water heater 100, and reduce energy consumption. Wherein, the heat-insulating layer can be made of foam material.

In an optional embodiment, the phase change water heater further includes a partition plate 18, the partition plate 18 divides the chamber 11 into a first installation cavity and a second installation cavity which are independent from each other and are closed to each other, one of the waterway control system 40 and the liner 20 is disposed in the first installation cavity, and the other is disposed in the second installation cavity. Therefore, the heat insulation material can be prevented from entering the waterway system 40, and the circuit safety is ensured.

As shown in fig. 1, the heater 50 may generally include: a housing 51 and a plurality of heating tubes 52.

Specifically, as shown in FIG. 11, the housing 451 defines a heating water channel having an inlet and an outlet, and a plurality of heating pipes 452 extend at least partially into the heating water channel.
