Heat-generating assembly and water heater

Abstract

A heat-generating assembly, including: a water inlet pipe, a water outlet pipe and a heat-generating pipe. The water inlet pipe has a second water inlet and a second water outlet, and a first connection pipe is in communication with the second water outlet. The heat-generating pipe has a first water inlet and a first water outlet that are oppositely disposed, and the first connection pipe is in communication with the first water inlet. An axis of the first connection pipe is staggered with an axis of the heat-generating pipe. The water outlet pipe is in communication with the first water outlet.

What is claimed is: 
     
         1 . A heat-generating assembly, comprising:
 a water inlet pipe and at least one first connection pipe, the water inlet pipe having a second water inlet and at least one second water outlet, the at least one first connection pipe being in communication with the at least one second water outlet;   at least one heat-generating pipe, comprising a first water inlet and a first water outlet oppositely disposed, the at least one first connection pipe being in communication with the first water inlet, an axis of the at least one first connection pipe being not coplanar with an axis of the at least one heat-generating pipe; and   a water outlet pipe, in communication with the first water outlet.   
     
     
         2 . The heat-generating assembly according to  claim 1 , wherein the at least one heat-generating pipe comprises a housing and a cover body coupled to the housing, the first water inlet being disposed at the cover body, the first water outlet being disposed at the housing, the at least one first connection pipe being in communication with the cover body. 
     
     
         3 . The heat-generating assembly according to  claim 2 , wherein the cover body is integrally formed with the at least one first connection pipe. 
     
     
         4 . The heat-generating assembly according to  claim 2 , wherein the at least one first connection pipe is a straight pipe, an extension direction of this straight pipe being tangent to an inner wall surface of the cover body. 
     
     
         5 . The heat-generating assembly according to  claim 1 , wherein,
 the at least one heat-generating pipe comprises a plurality of heat-generating pipes;   the at least one first connection pipe comprises a plurality of first connection pipes;   the at least one second water outlet comprises a plurality of second water outlets; and   the plurality of heat-generating pipes, the plurality of first connection pipes and the plurality of second water outlet are disposed in a one-to-one correspondence respectively.   
     
     
         6 . The heat-generating assembly according to  claim 5 , wherein for any two adjacent first connection pipes, the first connection pipe that is away from the second water inlet has an open area that is smaller than an open area of the first connection pipe that is closer to the second water inlet. 
     
     
         7 . The heat-generating assembly according to  claim 5 , wherein the plurality of second water outlets are located at a same height. 
     
     
         8 . The heat-generating assembly according to  claim 5 , wherein the plurality of first connection pipes are located at a same height. 
     
     
         9 . The heat-generating assembly according to  claim 5 , wherein the first water outlets of the plurality of heat-generating pipes are sequentially connected and in communication with one another, and wherein the first water outlet of one of the plurality of heat-generating pipes is directly in communication with the water outlet pipe. 
     
     
         10 . The heat-generating assembly according to  claim 1 , wherein the first water inlet is located at a bottom of the at least one heat-generating pipe, and wherein the first water outlet is located at a top of the at least one heat-generating pipe. 
     
     
         11 . The heat-generating assembly according to  claim 1 , wherein the heat-generating assembly further comprises a fix member, wherein the fix member is fixedly connected to the plurality of heat-generating pipes and/or is fixedly connected to the plurality of heat-generating pipes, and one of the water inlet pipe and the water outlet pipe. 
     
     
         12 . The heat-generating assembly according to  claim 1 , wherein the at least one first connection pipe is perpendicular to the water inlet pipe. 
     
     
         13 . A water heater, comprising a heat-generating assembly which comprises:
 a water inlet pipe and at least one first connection pipe, the water inlet pipe having a second water inlet and at least one second water outlet, the at least one first connection pipe being in communication with the at least one second water outlet;   at least one heat-generating pipe, comprising a first water inlet and a first water outlet oppositely disposed, the at least one first connection pipe being in communication with the first water inlet, an axis of the at least one first connection pipe being not coplanar with an axis of the at least one heat-generating pipe; and   a water outlet pipe, in communication with the first water outlet.
