Specific embodiment

The principles of the present invention and spirit are described below with reference to several illustrative embodiments.It should be appreciated that giving These embodiments are out just for the sake of making those skilled in the art can better understand that realize the utility model in turn, and simultaneously It is non-to limit the scope of the utility model in any way.On the contrary, thesing embodiments are provided so that the disclosure is more thorough With it is complete, and the scope of the present disclosure can be completely communicated to those skilled in the art.

The embodiments of the present invention are intended to provide a kind of water tank for water heater, by being arranged on the pipeline of water tank One or more acclivitous blind pipes can effectively eliminate more than in pipeline after water freezing volume expansion due to generate to water tank Destructive power.

After describing the basic principle of the utility model, lower mask body introduces the various non-limiting of the utility model Embodiment.

Fig. 1 shows the structural schematic diagram of the water tank of the present embodiment.As shown in Figure 1, the water tank of the present embodiment may include Cabinet 100 and pipeline 200, can be applied in the water heater of such as gas heater.

Wherein, cabinet 100 have can supplied gas flowing inner cavity.For example, during gas water heater working, burning High-temperature flue gas afterwards can enter in the inner cavity of cabinet 100.Pipeline 200 has the inner cavity flowed for liquid.For example, in combustion gas During water heater working, there is water flow in pipeline 200, and the water in pipeline 200 is being heated to form heat after cabinet 100 Water.

Pipeline 200 may include the coil pipe 210, water inlet pipe 220 and outlet pipe 230 being connected.Wherein, coil pipe 210 is surround In the outside of cabinet 100, and can be contacted with cabinet 100.Preferably, 210 coiled coil of coil pipe is looped around the four of cabinet 100 Week, to increase the contact area with cabinet 100.Water inlet pipe 220 has water inlet end 221, and water inlet end 221 can pass through water supply connector 222 connect with cold water source, to convey cold water into the inner cavity of pipeline 200.Outlet pipe 230 has water outlet 231, water outlet 231 It can be connect by water outlet connector 232 with the output end of hot water of water heater, the hot water in 200 inner cavity of pipeline is exported.

Pipeline 200 can be integrally formed, and can also be made of the coil pipe 210, water inlet pipe 220 and outlet pipe being seamlessly connected, As long as guaranteeing the inner cavity for forming perforation in pipeline 200, and flowed for liquid.In this implementation, the mode of seamless connection can be with It also may include being connected by connector including welding.

The blind pipes 300 that the water tank of the present embodiment can also be connected including one or more with pipeline 300, and blind pipe 300 are obliquely installed upwards, to utilize gravity, make water tank normal condition (may include working condition and inoperative shape body) Under, water is not had to be entered in blind pipe 300.

When ambient temperature is too low, remaining water may freeze in pipeline 200；When ice starts to contact in pipeline 200 When wall, due to can also continue to spread into blind pipe 300 there are the volume of blind pipe 300, ice, without by the inner wall of pipeline 200 Barrier also would not generate destructive power to the inner wall of pipeline 200, to reduce a possibility that pipeline 200 is by spalling (bursting by freezing).

It should be noted that having carried out example in the present embodiment with three blind pipes 300, but this is not the number to blind pipe The restriction of amount and setting position.In addition, in the present embodiment, when the quantity of blind pipe is multiple, the size of each blind pipe and incline Rake angle can not be identical.

In the present embodiment, it also may include by connecing that the mode that blind pipe 300 is connected with pipeline 200, which may include welding, Head connection.In addition, the diameter of blind pipe 300 can be less than the diameter of pipeline 200, to facilitate processing and connection.

In one embodiment, one or more blind pipes being connected to water inlet pipe 220 can be set on water inlet pipe 220 300, also, the position of blind pipe 300 is preferably arranged close to water inlet end 221, and then avoids the water inlet end 221 for being easy residual ponding There is bursting by freezing.

In one embodiment, one or more blind pipes being connected to outlet pipe 230 can be set on outlet pipe 230 300, and the position of blind pipe 300 is preferably arranged close to water outlet 231, and then avoids the water outlet 221 for being easy residual ponding Bursting by freezing occurs.

In one embodiment, one or more blind pipes 300 being connected to coil pipe 210 can be set on coil pipe 210, And the position of blind pipe 300 is preferably the top of coil pipe 210.For example, blind pipe 300 is arranged on that uppermost root coil pipe.By It can be connected to by flue with outdoor in cabinet 100, as cold air enters from top to down, be easy to happen at the top of coil pipe 210 Therefore bursting by freezing risk can be effectively reduced in the top that coil pipe 210 is arranged in the position of blind pipe 300 by bursting by freezing.

It in one embodiment, can be near water inlet end 221, near end 231 of the publishing books and top part of coil pipe 210 The blind pipe 300 that one or more She Zhi not be connected to pipeline 200.

In one embodiment, blind pipe 300 can have closed end 310, as shown in Figure 2.

In one embodiment, as shown in Figure 1, the water tank of the present embodiment can also include multiple fins being arranged in juxtaposition 400, it is set to the top of the inner cavity of cabinet 100；Pipeline 200 can also include heat transfer water pipe 240, be connected to coil pipe 210 and go out Between water pipe 230, and it is connected with coil pipe 210 and outlet pipe 230.The water pipe 240 that conducts heat passes through multiple fins 400.For example, every The hole passed through for heat transfer water pipe 240 is provided on a fin 400.High-temperature flue gas enters where fin 400 from the inner cavity of cabinet 100 Region, transfer heat to heat transfer water pipe in water, so that cold water is become hot water.

The utility model embodiment also provides a kind of water heater, including water tank described in a kind of embodiment of any of the above, Other compositions of water heater can be used in the various technical solutions that those of ordinary skill in the art will know with future now, here It is not described in detail.

The utility model embodiment provides a kind of water tank and water heater applied to water heater, by being arranged on pipeline Acclivitous blind pipe, can be to avoid tank pipe by bursting by freezing.Further, be easy to happen the water inlet pipe of bursting by freezing risk into Water end (W.E.) is neighbouring, outlet pipe water outlet is neighbouring and one or more coil pipes are arranged in the top of coil pipe, and bursting by freezing can be effectively reduced Risk, and save cost.
