The embodiments described below are exemplary by referring to the drawings for the purpose of illustrating the utility model and are not to be construed as limiting the utility model.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows, or may be learned by practice of the utility model.
Example 1
Referring to fig. 1, a heat exchange type electric water heater comprises a heat exchange box body 1, a heat storage heater 2, a heat exchanger 3, an instant heating heater 4 and a thermostatic valve 5, wherein the heat storage heater 2 is arranged in the heat exchange box body 1 and is used for heating heat exchange liquid in the heat exchange box body 1, the heat exchanger 3 is soaked in the heat exchange liquid and is used for exchanging heat to heat water flow flowing through, the instant heating heater 4 is connected to a hot water outlet of the heat exchange type electric water heater, and the thermostatic valve 5 is connected between a hot water outlet and a cold water pipe of the heat exchange type electric water heater and is used for keeping constant temperature.
Different from the traditional water storage type electric water heater, the heat exchange box body 1 in the embodiment is an open box body, and an open liquid inlet pipe 6 and an open liquid outlet pipe 7 are arranged on the heat exchange box body 1. Heat exchange liquid (such as water flow and the like) flows into the bottom of the heat exchange box body 1 from the liquid inlet pipe 6 and naturally overflows from the liquid outlet pipe 7; the heat exchange box body 1 does not bear the pressure of the inlet liquid and the expansion pressure of heating, and the service life can be effectively prolonged. In addition, the whole box body is not filled with the heat exchange liquid in the heat exchange box body 1, and a part of space is reserved at the top of the box body and is used as a volume expansion space when the heat exchange liquid is heated. Because the heat exchange box body 1 in the embodiment is open, the shape of the heat exchange box body is diversified, and the shape of the water heater can be adjusted at will, so that the shape constraint of the traditional large barrel water heater is eliminated.
In this embodiment, the heat exchange liquid is preferably water, and in some embodiments, the heat exchange liquid may be another heat transfer liquid with a high specific heat capacity, such as an oil or the like.
In this embodiment, it is preferable that the heat storage heater 2 is disposed at the bottom of the heat exchange box 1, so as to improve heating efficiency and heat of the heat exchange liquid in the heat exchange box 1, and ensure temperature uniformity of the heat exchange liquid.
In this embodiment, it is preferable that a casing 8 is provided outside the heat exchange tank 1, and an insulation layer 9 is provided between the casing 8 and the heat exchange tank 1, for insulating the heat exchange liquid in the heat exchange tank 1. The heat insulating layer may be foamed material, EPS, rubber and plastic cotton, vacuum heat insulating board, glass fiber cotton, etc.
In this embodiment, the heat exchanger 3 is preferably a stainless steel heat exchange pipeline, and is immersed in the heat exchange liquid. In some embodiments, the heat exchanger 3 may be a plate-type structure or the like, known in the art or available in the future.
In order to ensure a more sufficient amount of hot water, in this embodiment, it is preferable that the instant heating heater 4 is an overcurrent heater, and the instant heating heater 4 is connected to the water outlet end of the thermostatic valve 5 and is used for further heating the mixed water flowing out after being mixed by the thermostatic valve 5 to reach the bath water temperature of the user. So arranged, the water for the user to bath is not stored water but flowing running water.
The specific working principle is as follows: when the heat exchange liquid in the heat exchange tank 1 is heated by the heat storage heater 2, the temperature becomes 75 ℃. At this time, water starts to flow in from the water inlet of the heat exchanger 3, and water (15 ℃) for bath of a user flows into the heat exchanger 3, and part of water enters the heat exchanger 3 for heat exchange and the other part enters the thermostatic valve 5. The water temperature of the water entering the heat exchanger 3 is increased (65 ℃) after heat exchange to become hot water, the hot water and the cold water flowing into the thermostatic valve 5 are mixed and then flow out of the mixed water (25 ℃), and the mixed water flows into the instant heater 4 for further heating, so that the bath temperature of a user (40 ℃) is finally reached. By the arrangement, the heat stored in the water tank can be utilized to the greatest extent, and the maximum hot water quantity is provided.
In some embodiments, the instant heater 4 may instead be arranged between the water outlet end of the heat exchanger 3 and the hot water inlet of the thermostatic valve 5, as shown in fig. 2; or instead on the cold water inlet of the thermostatic valve 5, as shown in figure 3; similar effects can be achieved, but each element can bear too high temperature water, the service life of each element is reduced, and meanwhile, the problems of high heat loss and low heat utilization rate are also caused.
