Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment one.
Fig. 2 is the structural schematic diagram of the utility model embodiment two.
Fig. 3 is the structural schematic diagram of the utility model embodiment three.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Embodiment one
Referring to Fig. 1, this liquid heating, including the internal cartridge heater 1 for being equipped with heating cavity, cartridge heater 1 may include cylinder
Body and cover, stack shell and cover can be made up of conventional drawing or Sheet Metal Forming Technology respectively, then are tightly connected by welding manner
Integrally, processing technology is simple, automationization is suitble to quickly to produce, and helping reduces cost, and those skilled in the art can manage
Solution, the both ends of 1 length direction of cartridge heater are respectively equipped with the water inlet 11 and water outlet 12 of connection heating cavity, the heating cavity
The interior length direction along cartridge heater 1 is equipped at intervals with several layers partition 2, and heating cavity is separated into independent water flow by partition 2 layer by layer
Channel, partition 2 are equipped with apopore 21, and the apopore 21 of adjacent two pieces of partitions 2 is located at the opposite sides of heating cavity, out
Water hole 21 is connected to adjacent water stream channel, and all water stream channels is made to constitute the channel of a continuous s shape trend, water inlet 11, water
Circulation road and water outlet 12 successively constitute water heating flow channel.Water flow exchanges heat when flowing through water heating flow channel with cartridge heater 1, in water flow
During flowing through water heating flow channel, since water energy stops in the water stream channel of multilayer, circulates, it can increase and cartridge heater
Contact area and time of contact, enable water to sufficiently exchange heat with cartridge heater, realize the purpose that quickly heats.
Further, the partition 2 is made up of metal sheet punching press, or is made or leads to by plastics integrated injection molding
It crosses metal integrated die-casting to be made, in the form of sheets, the mold for being used in production partition 2 is equally simple for partition 2, equally helps reduction production
Cost.
Further, (the present embodiment is preferably at it equipped with the flange 22 to turn up to unilateral side for the center of the partition 2 or outer rim
Flange 22 is arranged in center), 22 opposed separators of flange, 2 protrusion, adjacent two pieces of partitions 2 abut each other positioning by flange 22, make phase
The spacing distance of adjacent two pieces of partitions 2 is identical as the raised height of partition 2 of flange 22, which can not only rapidly add
The intracavitary installation multilayer insulating panel 2 of thermal capacitance, additionally it is possible to guarantee that the distance of every layer of partition 2 is consistent, guarantee the water of every layer of water stream channel
It is consistent to flow circulation.
Further, the outer surface of the cartridge heater 1 is equipped with calandria 4, meets the heating to cartridge heater 1.And calandria 4
Preferably thick-film heating body.
Further, the center of the cartridge heater 1 is equipped with the stud shaft 3 being arranged along its length, and partition 2 is mounted on stud shaft
On 3, partition 2 can be pre-installed on stud shaft 3, and the two is together mounted in heating cavity after assembling, and be assembled more quick.
Embodiment two
As shown in embodiment one, stud shaft 3 be it is cylindric, i.e., the volume of its every layer water stream channel is all the same, that is to say, that
Every layer of water stream channel water inside it residence time be it is identical, this, which will likely result in water flow temperature close to water inlet, to compare
Water flow temperature close to water outlet is much lower, since the thermometric of water flow is the mean temperature for testing cartridge heater 1, thus, it is easy to lead
Cause leaving water temperature often higher than the test temperature of water flow, when especially leaving water temperature is adjusted to 100 degree, since water flow is logical in water flow
The residence time in the road too long a large amount of water vapours of generation, are easy to appear water outlet spraying steam phenomenon.
To solve the above-mentioned problems, referring to fig. 2, this liquid heating is with the main distinction of first embodiment,
The stud shaft 3 becomes larger along the water inlet direction of cartridge heater 1, its outer diameter.This makes the volume of every layer of water stream channel along water inlet
Direction is gradually reduced, i.e. water flow rests on the water, time reduction of every layer of water stream channel during flowing through heating cavity,
That is the heat-exchange time of water and cartridge heater 1 is shorter, at this point, the water flow close to water inlet 11 can be guaranteed by more time and cartridge heater
1 heat exchange, the water flow close to water outlet 12 can quickly flow out, which can make the water flow temperature of close water inlet and lean on
The water flow temperature of nearly water outlet is more close, utmostly reduces leaving water temperature error, effectively realizes the accurate control of leaving water temperature
System, avoids the problem that water flow generates a large amount of water vapours because heating time is too long, avoids the occurrence of water outlet spraying steam phenomenon.
Wherein, the stud shaft 3 of described the present embodiment is step column, the water inlet direction in direction and cartridge heater 1 that step increases
It is identical.
Other not described parts, same first embodiment are not repeated.
Embodiment three
Referring to Fig. 3, this liquid heating is with the main distinction of second embodiment, and the stud shaft 3 is taper
Column, the direction that outer diameter increases are identical as the water inlet direction of cartridge heater 1.
Other not described parts, same second embodiment are not repeated.
Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent deformation or replacement without departing from the spirit of the present invention, these equivalent changes
Type or replacement are all contained in range set by the claim of this application.
