Background technology
Existing water heater mainly is divided into storage-type electric water heater, immediately heating water heater and fast heating type water heater.The advantage of storage-type electric water heater mainly is that power is little, and is less demanding to circuit, low price; Immediately heating water heater is small and exquisite, power saving, and firing rate is fast, but power is high to the circuit requirement greatly, and power was too big when particularly used the winter in colder area in the north, and the circuit of common town-dweller-rural-family can't satisfy instructions for use.And the fast heating type water heater combines the advantage of storage-type and immediately heating water heater, can also can realize instant heating under certain condition by the low capacity water storage.
The fast heating type water heater that has had on the market mainly be by near outlet pipe, coil electric heating tube, make flow to outlet pipe water in the very short time by Fast Heating.The shortcoming of this method is not separate between near the outlet pipe water inlet hot water and the cold water on every side, can heat convection, cause by electrothermal tube rapidly the water of heating be cooled, make the hot water delivery rate reduction.And no matter existing water heater is the water heater of which kind of form heating, its heating tube directly contacts with water usually, because the hardness ratio of running water is higher, when heating, be easy to adhere to thicker incrustation scale on the tube wall at heating tube, seriously influence the service life of heating tube.
The utility model content
The utility model aims to provide the hot assembly of a kind of speed and comprises its water heater, to solve the low and heating tube technical problem that reduce service life owing to adhere to incrustation scale of water heater hot-water output rating in the prior art.
To achieve these goals, according to an aspect of the present utility model, a kind of fast hot assembly that is used for water heater is provided, and the hot assembly of this speed comprises: cartridge heater, this cartridge heater comprise end cap, the diapire relative with end cap, the sidewall and the inner chamber of link lid and bottom wall; Heating tube is arranged in the sidewall of cartridge heater; Water inlet pipe, first end stretches in the inner chamber, second end with stretch out inner chamber; And outlet pipe, first end stretches in the inner chamber, and second end stretches out inner chamber.
Further, heating tube is injection-moulded in the sidewall of cartridge heater.
Further, sidewall has the hollow layer that is formed by madial wall and lateral wall, and heating tube is arranged in this hollow layer.
Further, also be provided with the temperature-sensing probe hole in the sidewall of cartridge heater, the temperature-sensing probe hole is the cecum hole towards the direction of inner chamber, and temperature-sensing probe is arranged in the temperature-sensing probe hole.
Further, inner chamber has the trapezoid cross section.
Further, heating tube is U type or spirality.
Further, first end of water inlet pipe passes end cap and stretches in the inner chamber, and first end of outlet pipe passes diapire and stretches in the inner chamber, and outlet pipe first end is to extend beyond the first end preset distance of water inlet pipe to end cap.
Further, outlet pipe first end extends to the position of contiguous end cap, and first end of water inlet pipe extends to the position of adjacent bottom wall.
According on the other hand of the present utility model, a kind of quick-acting water heater is provided, comprise the hot assembly of above-mentioned speed, the hot assembly of this speed is arranged in the inner bag of quick-acting water heater.
Further, be threaded between the bottom of fast hot assembly and the inner bag, and be provided with sealing ring between diapire and the inner bag.
Use the hot assembly of speed of the present utility model, on the one hand, water is got together by Heating tube in the process that flows out, and concentrated heating has been avoided and tube cold water convection current outward, thereby has reduced the dispersion of fast heat; And the time that current are flowed through in Heating tube is long, and it is long to be heated the time, and hot water delivery rate is improved greatly; On the other hand, hot-water line is arranged in the sidewall of cartridge heater, avoided contacting with the direct of water, has solved heating tube in the prior art because fouling and the technical problem that shortens service life.
