Embodiment Construction

[0011] Below in conjunction with the accompanying drawings, the present invention will be further described: when the water heater is working, the static liquid water 3 is first heated to a high temperature of 60-95 degrees by the heating unit 7, and then the cold water enters the tubular heat exchanger 4 from the water inlet pipe 5 during use. , exchange heat with the high-temperature static liquid water 3 through the heat exchanger 4, and then flow out from the water outlet pipe 1, thereby heating the cold water into hot water suitable for domestic use.

[0012] During implementation, there are the following details:

[0013] 1. The floating ball can be used to control the water level of the liquid water in the static water tank.

[0014] 2. The heating unit can be heated by gas, electricity or air energy, especially electric and air energy water heaters.

[0015] 3. In order to avoid freezing when not in use, an appropriate concentration of salt can be added to the liquid ...

Abstract

The invention provides an indirect type water heater. The water heater comprises a water tank inner container, a heating unit, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are separately connected with the tow ends of a pressureproof tubular exchanger, the tubular exchanger is arranged in a water tank, the water tank can adopts non-pressure type structure; in the water heater, static water in the water tank heated by the heating unit indirectly provides heat for the free water in the tubular exchanger, owning to the small caliber of the tubular exchanger, the durable pressure is greatly increased so that the material used for producing the pressure structure has low cost and the water accumulating volume of the pipes is low; and the heat of the water in the water tank is transferred for heating and the residence time is short so that the scaling phenomenon is largely reduced and icing-up damage is not easy to cause, thus the indirect type water heater can be widely used in household and small units.

Description

technical field [0001] The invention relates to a water heater, in particular to a water tank structure of the water heater. Background technique [0002] At present, the heating structure of water heaters includes external heating, such as solar water heaters and gas water heaters, and internal heating, such as electric water heaters; according to the location of the water tank, the inner tank of the water heater is divided into a pressure-bearing type and a non-pressure-bearing type. Non-pressure-bearing type is mostly used, and gas and electric water heaters are mostly indoors, driven by tap water pressure, so pressure-bearing type is used. [0003] The general material requirements of the pressure-bearing type are relatively high. At present, 304 food-grade stainless steel is mostly used as the inner tank material, and because of the pursuit of pressure, the inner tank plate needs a certain thickness, which will increase the cost of the water heater. [0004] At the sam...
