Detailed Description

To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 1 and fig. 2, the present invention discloses a heat storage type water heater, which comprises a housing 1, a heat storage medium (not shown in the figure), a heat exchanger 2, a heater 3 and at least one electromagnetic coil panel 4; the heat storage medium and the heat exchanger 2 are both arranged in the shell 1, and the water inlet end 21 and the water outlet end 22 of the heat exchanger 2 are both arranged outside the shell 1; the heater 3 is arranged on the shell 1 (can be in the shell 1 or outside the shell 1), the electromagnetic coil panel 4 is arranged on the outer side surface of the shell 1, and the electromagnetic coil panel 4 generates an alternating magnetic field to enable the heater 3 to generate heat in an induction manner so as to heat the heat storage medium in the shell 1, so that the heat storage medium is supplemented with heat for storage.

The utility model discloses use the cooperation of heater and electromagnetic coil panel, heat the heat-retaining medium based on the induction heating mode, because heater 3 generates heat through electromagnetic induction, itself not with power supply electric connection, consequently, even heat exchanger 2 leaks by accident, in water leaks casing 1, water also can not be electrified to avoid the use risk of electric shock, improved the safety in utilization.

Wherein, the heat storage medium comprises water, oil, salt particles, mineral powder or phase-change materials, etc.

Wherein, the heater 3 is made of material with good magnetic permeability, for example, the heater 3 is made of carbon steel, iron or stainless iron.

Preferably, the heater 3 is disposed on the bottom of the housing 1 (which may be the bottom inner side or the bottom outer side), and the solenoid disk 4 is disposed on the bottom outer side of the housing 1. To simplify the assembly and construction of the heater 3, in one embodiment the heater 3 is served by the floor of the housing 1.

In one embodiment, a supply opening 11 is provided in the housing 1, and the supply opening 11 is convenient for a user to replenish the heat storage medium in the housing 1 as required during use.

In one embodiment, a pressure relief vent 12 is provided in the housing 1, and preferably the vent 12 is provided generally at the top of the housing 1. Through setting up pressure release 12, avoid casing 1 top not to be full of the heat-retaining too big casing 1 that leads to of the space partial pressure that ends, be favorable to improving heat storage formula water heater's life.

As is known, the heat exchanger 2 is formed by a continuous curved pipe, and is arranged in a curved manner to meet the dimensional requirements of the installation space in the housing 1, and has a larger surface area as much as possible to increase the direct thermal contact area with the heat storage medium, thereby improving the heat exchange capacity.

As further shown in connection with fig. 3. In a preferred embodiment, water is used as the heat storage medium for the convenience of users, in this case, the housing 1 is filled with water as the heat storage medium as required, and the heat exchanger 2 is soaked in the water as the heat storage medium in the housing 1, but the water flowing through the heat exchanger 2 and the water as the heat storage medium need to be heated by heat exchange through the heat exchanger 2. Specifically, the thermal storage water heater further includes: the three-way joint is used for being connected with a water supply source and comprises a three-way joint 5, an electromagnetic valve 6 and a thermostatic valve 7, wherein one water outlet joint of the three-way joint 5 is communicated with a material supply port 11 through the electromagnetic valve 6, the other two water outlet joints of the three-way joint 5 are respectively communicated with a water inlet end 21 of a heat exchanger 2 and a cold water interface of the thermostatic valve 7, a hot water interface of the thermostatic valve 7 is communicated with a water outlet end 22 of the heat exchanger 2, and a water outlet interface of the thermostatic valve 7 is used as a hot water outlet of the heat storage.

The heat storage type water heater can provide constant-temperature hot water through heat exchange, and the working principle is as follows: if a user needs to obtain hot water with the temperature of T0, cold water with the temperature of T1 provided by a water supply source respectively supplies water to the water inlet end 21 of the heat exchanger 2 and the cold water interface of the thermostatic valve 7 through the three-way joint, the cold water performs sufficient heat exchange with the heat storage medium in the process of flowing into the heat exchanger 2 to the water outlet end 22, hot water with the temperature of T2 flows out of the water outlet end 22, part of the cold water with the temperature of T1 is mixed with the hot water with the temperature of T2 through the thermostatic valve 7, and finally the hot water with the temperature of T0 flows out of the water outlet interface of the thermostatic valve 7. Wherein T1 is more than T0 and less than or equal to T2.

If the temperature T2 of the hot water flowing out from the water outlet 22 is lower than the temperature T0 required by the constant temperature hot water, it is considered that the heat storage medium cannot continuously exchange heat and needs to supplement heat, at this time, the electromagnetic coil panel 4 is powered on to generate an alternating magnetic field, and the heater 3 inductively heats in the alternating magnetic field to heat the heat storage medium in the shell 1, so that the heat storage medium supplements heat for storage.

Certainly, be equipped with level sensor in casing 1 and detect the liquid level height of the interior water that is the heat-retaining medium of casing 1, heat storage formula water heater still includes control circuit board, level sensor and solenoid valve all with control circuit board electric connection, when control circuit board passes through level sensor and judges that the liquid level height in casing 1 is less than the default, control circuit board control solenoid valve switches on, lets the cold water at water supply source pass through three way connection and supplies water in casing 1 through feed inlet 11.
