Heat accumulation；Phase-change material becomes solid-state, heat-storing material heat release by liquid., by solid state into liquid state, heat-storing material can for phase-change material
By the converting heat of the coolant in heating pipeline 122 into latent heat and in the heat-storing material that is stored in canister 121, until storing
Hot material all becomes liquid, and the heat accumulation process of heat-storing material terminates.When phase-change material becomes solid-state by liquid, heat-storing material is put
With the water in heating drain pipe road 110, until heat-storing material all becomes solid-state, the exothermic process of heat-storing material terminates heat.
Further, the scope of the specific heat capacity of heat-storing material is 1.8J/g*k～2.5J/g*k；The heat conduction system of heat-storing material
Several scopes is 3W/m* DEG C～5W/m* DEG C, preferably 4W/m* DEG C.To consider the uncertainty of Hot water units power-off, in specific heat capacity
And the heat-storing material in the range of heat conductivity ensure that lasting Exotherm Time, it is to avoid the water freezing in drainage pipeline 110.At this
In utility model, it is desirable to which heat-storing material is at least six hours to the water continuous heating time in drainage pipeline 110, and pass through accumulation of heat
The scope of the specific heat capacity of material is 4W/m* DEG C of the heat conductivity of 1.8J/g*k～2.5J/g*k and heat-storing material ensureing.When
Hot water units power supply disconnects, and when the temperature of the water in drainage pipeline 110 is less than 0 DEG C, heat-storing material slowly releases heat, to draining
Water in pipeline 110 is heated, it is ensured that water is liquid always.Drain pipe can so be avoided by bursting by freezing, it is ensured that hot water machine
The pipeline safety of group, improves the service life of Hot water units, reduces the problem after sale of Hot water units so that the reliability of product
Property is greatly promoted.
This utility model additionally provides a kind of Hot water units, including exhaustor 200 and the discharge structure in above-described embodiment
100.Exhaustor 200 is connected with the heating pipeline 122 of discharge structure 100 by capillary tube 123, realizes the storage of discharge structure 100
The accumulation of heat of hot component 120.By discharge structure 100, Hot water units of the present utility model ensure that the water in drainage pipeline 110 is not tied
Ice, avoids then drainage pipeline 110 from freezing, it is ensured that the safety of the pipe-line system of Hot water units, improves making for Hot water units
