The liquid heaters such as electric kettle in order to power off in time after the completion of heating, it will usually include steam cock, steam Vapour switch is connected with the heating device on liner 11.After liquid boiling in electric kettle, a large amount of steam can be generated, steam is opened It is after pass touches these steam, i.e., automatic to disconnect, thus by the dump of heating device, to stop the heating of heating container. Specifically, having generally comprised switch connecting rod and steam piece etc. in steam cock, e.g., the first steam cock includes the first steam piece 41, the second steam cock includes the second steam piece 42, heats steam caused by the liquid boiling in container and leads to steam piece, when When the steam that steam piece touches reaches a threshold value, steam piece control switch connecting rod is mobile, to disconnect the power supply of electric kettle. In addition, above-mentioned liner 11 can independently form kettle body 1, kettle body 1 can also be cooperatively formed with liner 11 and shell 12, certain pot Body 1 can also be vacuum kettle body 1.Kettle body component may include kettle body, bottom cover, handle and temperature controller etc..

Embodiment 1:

As shown in Figure 1, a kind of liquid heater, including 1 component of kettle body, 1 component of kettle body include liner 11, are set to liner 11 The handle 3 of side, the temperature controller 4 between liner 11 and bottom cover 2, and the steam port 111 and temperature controller 4 of connection liner 11 On steam cock steam channel, in order to realize dechlorination water boiling function and normal water boiling function selection switching, the steam Switch includes the first steam cock and the second steam cock, and the steam channel includes the first steam for the first working condition Channel and the second steam channel for the second working condition, further include switching switch 6, and the switching switch 6 is used to control institute The connection status of liner 11 Yu steam cock is stated, the switching switch 6 includes at least the first connection status and the second connection status； Under the first connection status, the liner 11 is connected to by the first steam channel with the first steam cock；In the second connection status Under, the liner 11 is connected to by the second steam channel with the second steam cock.

The first working condition and the second working condition in the embodiment of technical solution of the present invention can be freely combined and Selection, for example, the first working condition can be normal water boiling function, the second working condition can be dechlorination function；Or first Working condition can be sterilizing function for warm milk function, the second working condition, i.e., when need to the article being put into liner 11 into When row disinfection, under the second working condition, liquid heater long-time hot operation can be allowed to carry out disinfection；Alternatively, the first work State can be the water boiling function for region of no relief, and the first working condition can be the water boiling function ... etc. for uplift plateau Deng.

For following embodiment with the first working condition for normal water boiling function, the second working condition is that dechlorination water boiling function is Example, the present invention provide a kind of 6 structure of switching switch for realizing steam channel switching.The present embodiment is described in detail with reference to the accompanying drawing Structure:

In other words, by the selection of above-mentioned switching switch 6, dechlorination water boiling function and normal water boiling function are realized respectively, are used Person can select to need to dechlorinate and water boiling function or normal burn when using this liquid heater according to the water quality of actual use Water function；In addition, compared with the existing technology, the technical program uses two relatively independent steam cocks: the first steam is opened Pass and the second steam cock, realize above-mentioned dechlorination water boiling function and normal water boiling function respectively, do not interfere between each other, sufficiently arrive Up to respective purpose, effect is relatively reliable.In conclusion by adopting the above technical scheme, under different functions, by the first steam Steam is led to the first steam cock or the second steam cock respectively by channel and the second steam channel, and structure is simple, is not necessarily to electronics Vigour part, cost is lower, and dechlorination effect is good, while liquid heater can also meet the needs of different, rather than only single Dechlorination or normal heating demand.

In addition, first steam cock is different from the deformation temperature of the second steam cock:

For example, the deformation temperature of second steam cock is higher than the deformation temperature of the first steam cock.Pass through the jump of steam piece The working condition of two kinds of different function can be realized in disconnected temperature difference, and structure is simple, at low cost.

Further, first steam channel is the first steam pipe 51, and second steam channel is the second steam pipe 52, first steam pipe 51 is connected to the first steam cock, and second steam pipe 52 is connected to the second steam cock, described Switching switch 6 is used to open and close the air inlet of the first steam pipe 51 and the second steam pipe 52.When switching switch 6 opens the second steam pipe When 52 air inlet and the air inlet of the first steam pipe 51 of closing, i.e., when switching switch 6 is under the second connection status, liner 11 It is connected to the second steam cock, realizes dechlorination water boiling function；Conversely, when switching switch 6 opens the air inlet of the first steam pipe 51 When the air inlet of mouth and the second steam pipe 52 of closing, i.e., when switching switch 6 is under the first connection status, liner 11 and first steams Vapour switch connection, realizes normal water boiling function.Pass through two independent steam pipes of above-mentioned setting, better reliability, by cutting Switch 6 is changed by an inlet close in the first steam pipe 51 and the second steam pipe 52, can be realized the first connection status and Conversion between second connection status.

At this time without considering that the factor of the first steam pipe 51 and the second steam pipe 52 can also be to be simply that can be set into Two identical steam pipes, are connected to the first steam cock with the second steam cock respectively.Preferably, first steam cock Deformation temperature be 60-85 degrees Celsius (for 65 DEG C), the deformation temperature of second steam cock is 65-87 degrees Celsius (for 75 DEG C).

Certainly, in order to reduce the requirement to steam cock, the first steam channel and the second steam channel also be can be set into Difference, or in order to reach better effect, flow-path-length of the steam in first steam channel is less than described Flow-path-length in second steam channel, i.e. the second steam channel extend the time that steam reaches the second steam piece, into And heating time is extended, to reach dechlorination effect or other effects.

The mode for extending steam flow-path-length in steam channel, can be used following methods:

The first, as shown in Fig. 2, by the length of extension steam pipe, such as:

For example, the handle 3 includes handle set 3131 and handle 32, first steam pipe 51 is longitudinal to be set to the handle Between seat 3131 and liner 11, second steam pipe 52 is set in the handle 32, for the ease of switching the setting of switch 6, And reach and better use effect, the switching switch 6 is set on handle 3, and the switching switch 6 is for controlling the steam The on-off of mouth 111 and the first steam pipe 51 and the second steam pipe 52.By the way that the second steam pipe 52 to be equipped in handle 3, using now Some structures solve the installation question of the second steam pipe 52, while relative to the first steam pipe 51, also naturally prolonging The length for having grown steam pipe, the time for making steam reach the second steam cock through the second steam pipe 52 extends, and then extends and add The hot time has reached dechlorination effect；Meanwhile first steam be still set between handle 3 and liner 11, without change installation knot Structure, structure are simple.Certainly, first steam pipe 51 and the second steam pipe 52 can also be set to the handle 3 and liner 11 it Between, when the liquid heater further includes shell 12, the shell 12 and the cooperation of the handle 3 are disposed around the liner 11 Outside, shell 12 can also play the role of blocking steam pipe.

Second, by being arranged fuisw rib in steam pipe, in first steam pipe 51 and the second steam pipe 52 at least Fuisw rib is equipped in one steam pipe, the fuisw rib is staggered two-by-two in steam pipe, the fuisw rib and steam pipe Inner wall formed gap, the gap be flow-guiding channel.Such as:

In order to reach dechlorination effect, relative to the first steam pipe 51, fuisw rib is equipped in second steam pipe 52, it is described to lead Stream muscle is staggered two-by-two in the second steam pipe 52, and the inner wall of the fuisw rib and second steam pipe 52 forms gap, The gap is flow-guiding channel, and steam flows in the flow-guiding channel, and flow-guiding channel length is greater than the second steam pipe 52 at this time Vertical length, extend the time that steam reaches steam cock, and then extend heating time.Alternatively, the first steam pipe 51 It is respectively provided with fuisw rib with the second steam pipe 52, but fuisw rib is more than in the first steam pipe 51 in the second steam pipe 52.

For example, first steam pipe 51 and the second steam pipe 52 are set between the handle 3 and liner 11, institute The above-mentioned fuisw rib that is equipped in the second steam pipe 52 is stated, the switching switch 6 is set to 3 top of handle, and the switching switch 6 is used for Control the on-off of the steam port 111 and the first steam pipe 51 or the second steam pipe 52.

Alternatively, except above by the mode for extending steam flow-path-length in steam channel, to postpone steam cock The time sensed, the cross section of the second steam channel can also be greater than using the cross section of first steam channel, i.e., the The cross section of one steam pipe 51 is greater than the cross section of the second steam pipe 52, i.e. the caliber of the first steam pipe 51 is greater than the second steam pipe 52 caliber, so that it is different with the quantity of steam of the second steam pipe 52 by the first steam pipe 51, so that the first steam cock It is different from the jump of the second steam cock disconnected time.At this point, the caliber of the first steam pipe 51 is generally 8mm, the second steam pipe at this time Caliber be less than 8mm.

Using the cooperation of above-mentioned steam cock and steam channel, dual delay heating time is carried out, better effect is reached.

In addition to above scheme, flow-path-length of the steam in second steam channel be might be less that described Flow-path-length in one steam channel can reach other working conditions.Such as the work suitable for plateau and Plain, in height When former, the low boiling point of water, the disconnected temperature of jump of steam piece sets low, and the deformation temperature of first steam cock is at this time 30-55 degrees Celsius (for 40 DEG C), the deformation temperature of second steam cock is 65-87(for 75 DEG C) degree Celsius, But in order to also achieve the effect that dechlorination at plateau, lengthen flow-path-length of the steam in the first steam channel.

Further, field technical staff it is also contemplated that above-mentioned switching switch 6 in addition to that can be used to open and close the first steaming The air inlet of steam pipe 51 and the second steam pipe 52 can also be used to adjust into the first steam pipe 51 and the second steam pipe 52 simultaneously Quantity of steam, for example, the switching switch 6 is opening first respectively when the first steam pipe 51 and the second steam pipe 52 are identical When the air inlet of steam pipe 51 and the second steam pipe 52, the switching switch 6 can control the effective transversal of open air inlet Area is different, and the effective cross section product of the air inlet of the first steam pipe 51 is greater than the effective transversal of the air inlet of the second steam pipe 52 Area.

Further, the liquid heater further includes the power switch 7 with steam cock cooperation, is opened for the ease of power supply 7 movements are closed, gap of the power switch 7 between the first steam pipe 51 and the second steam pipe 52 stretches out in outside 1 component of kettle body Side.At this point, as shown in figure 3, being set on the vapor box 8 there are two inlet end 81, the first steam pipe 51 and the second steam pipe 52 divide It is not connect with two inlet ends 81.

Further, in order to enable the first steam cock and the environment of the second steam cock work are more independent, when described When first steam cock and the second steam cock are controlled with identical power switch 7 simultaneously, the first steam cock and the second steam When the disconnected direction of the jump of switch is identical, at this point, as shown in figure 4, first steam cock is set with the second steam cock horizontal Tile It sets, it is preferable that the temperature controller 4 further includes the vapor box 8 on the outside of the steam cock, and the vapor box 8 is respectively with described the One steam cock and the second steam cock and bottom cover 2 cooperatively form two vapor chambers.Alternatively, first steam cock and Partition is equipped between second steam cock, the inner wall of the bottom cover 2 upwardly extends to form the partition, and the partition is supported in temperature The lower surface for controlling 4 bracket of device, is separated the first steam cock and the second steam cock by aforementioned barriers.

Alternatively, when first steam cock and the second steam cock are controlled with identical power switch 7 simultaneously, first The jump of steam cock and the second steam cock break direction difference when, for example, first steam cock and the second steam cock are indulged To being arranged side by side, first steam cock is jumped disconnected upwards, and second steam cock, which is jumped downwards, to break, at this time power switch 7 The connecting rod of control steam cock is connect with the second steam piece upwards, or is connect with the first steam piece downwards, i.e. connecting rod and second When steam piece connects, connecting rod is driven to move downward when the second steam piece reaches deformation temperature, to disconnect power supply；Conversely, connecting rod When connecting with the first steam piece, connecting rod is driven to move upwards when the first steam piece reaches deformation temperature, to disconnect power supply, at this time Vapor box 8 not necessarily forms two vapor chambers.

The effect of above-mentioned vapor box 8 is for steam to be gathered in below steam cock, while preventing from leaking and influence other yuan Device.

Alternatively, when first steam cock is controlled with different power switches 7 simultaneously from the second steam cock, it is described Power switch 7 includes cooperating with the first power switch 7 of first steam cock cooperation and with second steam cock Second source switch 7.When only opening the first power switch 7, it could to state the first steam cock and connect to power supply, only When opening second source switch 7, it could to state the second steam cock and connect to power supply, at this time the first power switch 7 and second Power switch 7 can be used as switching switch 6 and use.

By adopting the above technical scheme, the first steam pipe 51 and when not identical the second steam pipe 52, the change of the second steam cock Shape temperature can be reduced suitably.
