背景技术Background technique
蒸汽拖把、蒸汽熨斗、蒸箱等电器设备中的蒸汽发生器通常是将发热管作为发热源,发热管对注入蒸汽发生器中的水进行加热,直至水变成蒸汽后从出汽口喷出。Steam generators in electrical equipment such as steam mops, steam irons, and steam boxes usually use heating pipes as heat sources. The heating pipes heat the water injected into the steam generator until the water turns into steam and then sprays out from the steam outlet .
为了对蒸汽发生器进行安全保护,蒸汽发生器上一般还设置有温控器,当蒸汽发生器中出现无水干烧的状况时,温控器跳断,发热管停止加热,蒸汽发生器逐渐冷却,当探测位置处的温度降低至温控器的恢复温度时,温控器恢复连接,发热管重新开始加热。In order to protect the steam generator, a thermostat is generally installed on the steam generator. When there is anhydrous dry burning in the steam generator, the thermostat trips, the heating tube stops heating, and the steam generator gradually cools down. , when the temperature at the detection position drops to the recovery temperature of the thermostat, the thermostat is reconnected, and the heating tube starts to heat again.
对于蒸汽拖把上的蒸汽发生器来说,蒸汽发生器不仅要随着蒸汽拖把一起移动,还会根据使用场景的不同而随着蒸汽拖把一起变换使用角度,比如,当蒸汽拖把在水平面上工作时,蒸汽发生器处于水平工作状态,当蒸汽拖把在倾斜面上工作时,蒸汽发生器变为倾斜工作状态,但是,相关技术中的蒸汽拖把在倾斜面上工作时,蒸汽发生器上的温控器容易出现超温跳断的情况而导致蒸汽拖把无法正常工作。For the steam generator on the steam mop, the steam generator should not only move with the steam mop, but also change the usage angle with the steam mop according to the different usage scenarios, for example, when the steam mop works on a horizontal surface , the steam generator is in a horizontal working state. When the steam mop works on an inclined surface, the steam generator becomes an inclined working state. However, when the steam mop in the related art works on an inclined surface, the temperature control on the steam generator The steam mop is prone to over-temperature tripping and the steam mop cannot work properly.

本申请另一实施例提供了一种电器设备,包括本申请任一实施例所提供的蒸汽发生器。Another embodiment of the present application provides an electrical device, including the steam generator provided by any embodiment of the present application.
电器设备可以是蒸汽拖把、蒸汽熨斗、蒸箱等任意一种需要使用蒸汽发生器的电器设备。The electrical equipment can be any electrical equipment that needs to use a steam generator, such as a steam mop, a steam iron, and a steam box.
发热管220的两端设置有电极,发热管220在通电的状态下能够持续发热,以将从进水口100a注入蒸汽发生器中的水加热成蒸汽。Electrodes are provided at both ends of the heating pipe 220, and the heating pipe 220 can continue to generate heat in the state of being energized, so as to heat the water injected into the steam generator from the water inlet 100a into steam.
温控器600用于检测感温区的温度,当温控器600检测到感温区的温度超过温控器600设定的动作温度时,温控器600跳断,与温控器600串联的发热管220停止加热,蒸汽发生器逐渐冷却,当感温区的温度降低至温控器600的恢复温度时,温控器600恢复连接,发热管220重新开始加热。The thermostat 600 is used to detect the temperature of the temperature sensing area. When the thermostat 600 detects that the temperature of the temperature sensing area exceeds the operating temperature set by the thermostat 600, the thermostat 600 is tripped and connected in series with the thermostat 600. The heating tube 220 stops heating, and the steam generator gradually cools down. When the temperature of the temperature sensing area drops to the recovery temperature of the thermostat 600, the thermostat 600 is reconnected, and the heating tube 220 starts to heat again.
具体地,本申请实施例的蒸汽发生器中设置有与进水口100a连通的进水通道2101a,水流从进水口100a流入进水通道2101a,然后再从进水通道2101a流入第一煮水腔2101b或第二煮水腔2101c中。在蒸汽发生器处于正放状态(即此时进水通道2101a对应的底壁位于进水通道2101a的下侧)下,请参阅图8,如果此时蒸汽发生器处于水平的正放状态,则从进水口100a流入进水通道2101a中的一部分水流会沿着进水通道2101a对应的底壁的内表面流入第一煮水腔2101b,另一部分水流会沿着进水通道2101a对应的底壁的内表面流入第二煮水腔2101c。如果蒸汽发生器发生倾斜而使得蒸汽发生器由水平的正放状态变为倾斜的正放状态,比如,请参阅图9,如果蒸汽 发生器从设置有第一煮水腔2101b的一侧朝设置有第二煮水腔2101c的一侧向下倾斜,则从进水口100a流入进水通道2101a中的水流至少会沿进水通道2101a对应的底壁的内表面流入第二煮水腔2101c中,请参阅图10,如果蒸汽发生器从设置有第二煮水腔2101c的一侧朝设置有第一煮水腔2101b的一侧向下倾斜的倾斜,则从进水口100a流入进水通道2101a中的水流至少会沿进水通道2101a对应的底壁的内表面流入第一煮水腔2101b中,也就是说,无论蒸汽发生器是处于水平的正放状态还是倾斜的正放状态,注入蒸汽发生器中的水流均能够沿进水通道2101a对应的底壁流入相应的煮水腔中,同时,由于进水通道2101a对应的底壁上的感温区的设置位置需满足从进水口100a流向第一煮水腔2101b的水流和从进水口100a流向第二煮水腔2101c的水流均流经感温区的至少部分区域,因此,在蒸汽发生器处于正放状态下,始终会有水流流经感温区并对感温区进行冷却,感温区不会出现无水干烧的状况,由此使得温控器600探测到的感温区的温度能够一直保持在温控器600所设定的动作温度之下,温控器600不会发生超温跳断的情况,从而可以使得发热管220能够一直保持在加热状态,进而可以使得流入对应的煮水腔中的水能够被发热管220至少加热至汽液混合态。也就是说,在蒸汽发生器处于正放状态下,无论蒸汽发生器是处于水平的正放状态还是倾斜的正放状态,蒸汽发生器都能够持续产生蒸汽,由此,可以使得蒸汽发生器能够在多种角度下正常工作。Specifically, the steam generator of the embodiment of the present application is provided with a water inlet channel 2101a that communicates with the water inlet 100a, and the water flows from the water inlet 100a into the water inlet channel 2101a, and then flows from the water inlet channel 2101a into the first water boiling cavity 2101b or in the second boiling water cavity 2101c. When the steam generator is in the normal release state (that is, the bottom wall corresponding to the water inlet channel 2101a is located on the lower side of the water inlet channel 2101a), please refer to FIG. 8, if the steam generator is in the horizontal positive release state at this time, then A part of the water flow from the water inlet 100a into the water inlet channel 2101a will flow into the first water boiling cavity 2101b along the inner surface of the bottom wall corresponding to the water inlet channel 2101a, and the other part of the water flow will flow along the bottom wall corresponding to the water inlet channel 2101a. The inner surface flows into the second water boiling chamber 2101c. If the steam generator is tilted so that the steam generator is changed from the horizontal upright state to the inclined upright state, for example, please refer to FIG. If the side with the second water boiling cavity 2101c is inclined downward, the water flowing from the water inlet 100a into the water inlet channel 2101a will flow into the second water boiling cavity 2101c at least along the inner surface of the bottom wall corresponding to the water inlet channel 2101a, Referring to FIG. 10 , if the steam generator is inclined downward from the side where the second water boiling chamber 2101c is provided to the side where the first water boiling chamber 2101b is provided, the steam generator will flow into the water inlet channel 2101a from the water inlet 100a The water flow will at least flow into the first boiling water cavity 2101b along the inner surface of the bottom wall corresponding to the water inlet channel 2101a. The water flow in the device can flow into the corresponding boiling water cavity along the bottom wall corresponding to the water inlet channel 2101a. At the same time, since the temperature sensing area on the bottom wall corresponding to the water inlet channel 2101a is set in a position that can flow from the water inlet 100a to the first The water flow of the first water boiling chamber 2101b and the water flow from the water inlet 100a to the second water boiling chamber 2101c both flow through at least part of the temperature sensing area. Therefore, when the steam generator is in the normal discharge state, there will always be water flow through The temperature sensing area is cooled and the temperature sensing area will not be dried without water, so that the temperature of the temperature sensing area detected by the thermostat 600 can always be maintained at the temperature set by the thermostat 600. Under the operating temperature, the thermostat 600 will not trip over temperature, so that the heating tube 220 can be kept in a heating state, and the water flowing into the corresponding boiling water cavity can be at least blown by the heating tube 220. Heat to a vapor-liquid mixture. That is to say, when the steam generator is in the positive discharge state, no matter whether the steam generator is in the horizontal positive discharge state or the inclined positive discharge state, the steam generator can continue to generate steam. Works fine at multiple angles.
本申请实施例的蒸汽发生器特别适用于蒸汽拖把这类具有多种使用角度的电器设备。The steam generator of the embodiment of the present application is particularly suitable for electrical equipment with various usage angles, such as a steam mop.
使从进水口100a流向第一煮水腔2101b的水流和从进水口100a流向第二煮水腔2101c的水流均能够流经感温区的至少部分区域的方式有多种,比如,一实施例中,请参阅图8,进水口100a位于进水通道2101a对应的底壁的上侧,感温区从进水口100a的正下方朝进水通道2101a沿延伸方向的相对两侧延伸,由此,在蒸汽发生器处于正放状态下,无论蒸汽发生器 是处于水平的正放状态还是倾斜的正放状态,从进水口100a流入进水通道2101a的水流都会在重力的作用下流到进水口100a下方的感温区上。There are various ways to enable the water flow from the water inlet 100a to the first water boiling chamber 2101b and the water flow from the water inlet 100a to the second water boiling chamber 2101c to flow through at least part of the temperature sensing area. For example, an embodiment 8, the water inlet 100a is located on the upper side of the bottom wall corresponding to the water inlet channel 2101a, and the temperature sensing area extends from directly below the water inlet 100a toward the opposite sides of the water inlet channel 2101a along the extending direction, thus, When the steam generator is in the positive discharge state, no matter whether the steam generator is in the horizontal positive discharge state or the inclined positive discharge state, the water flow from the water inlet 100a into the water inlet channel 2101a will flow to the bottom of the water inlet 100a under the action of gravity on the temperature sensing zone.
一实施例中,进水口100a的进水流量大于进水通道2101a的出水流量,也就是说,进水口100a的进水流量大于水流从进水通道2101a沿延伸方向的相对两侧流出的总流量,水流流入进水通道2101a中之后能够在短时间内充满整个进水通道2101a,由此,无论蒸汽发生器处于正放状态、倒置状态(即此时进水通道2101a对应的底壁位于进水通道2101a的上侧),或者其它特殊状态(比如蒸汽拖把在墙面上工作而使得发热芯210的进水通道2101a的延伸方向与水平面垂直),进水通道2101a中的水流始终会沿着进水通道2101a对应的底壁流动,其中的一部分水流会流入第一煮水腔2101b,另一部分水流会流入第二煮水腔2101c,也就是说,感温区上一直会有水流流过并对其进行冷却,感温区不会出现无水干烧的状况,从而可以使得蒸汽发生器能够在任意角度下正常工作,进而,当蒸汽拖把上使用该蒸汽发生器时,蒸汽拖把也可以在各种角度的工作面上正常使用。In one embodiment, the water inlet flow rate of the water inlet 100a is greater than the water outlet flow rate of the water inlet channel 2101a, that is, the water inlet flow rate of the water inlet port 100a is greater than the total flow rate of the water flowing out from the opposite sides of the water inlet channel 2101a along the extending direction , the water flow can fill the entire water inlet channel 2101a in a short period of time after flowing into the water inlet channel 2101a. Therefore, no matter whether the steam generator is in an upright state or an inverted state (that is, the bottom wall corresponding to the water inlet channel 2101a is located in the water inlet state at this time) the upper side of the channel 2101a), or other special conditions (for example, the steam mop works on the wall so that the extension direction of the water inlet channel 2101a of the heating core 210 is perpendicular to the horizontal plane), the water flow in the water inlet channel 2101a will always flow along the water inlet channel 2101a. The bottom wall corresponding to the water channel 2101a flows, a part of the water flow will flow into the first water boiling cavity 2101b, and the other part of the water flow will flow into the second water boiling cavity 2101c. It is cooled, and the temperature sensing area will not appear dry burning without water, so that the steam generator can work normally at any angle. Furthermore, when the steam generator is used on the steam mop, the steam mop can also be used in various Angled work surfaces are used normally.
需要说明的是,图9和图10中的进水通道2101a中示出的水流流动方向是指一般情况下,水流至少会流向的方向,当进水口100a的进水流量大于进水通道2101a的出水流量时,进水通道2101a中的部分水流会流入与图9和图10中所示的水流流动方向相反的煮水腔中,比如,如果蒸汽发生器处于处于图9所示的正放的倾斜状态,水流充满整个进水通道2101a之后,其中的一部分水流会流入第一煮水腔2101b中,如果蒸汽发生器处于处于图10所示的正放的倾斜状态,水流充满整个进水通道2101a之后,其中的一部分水流会流入第二煮水腔2101c中。It should be noted that the water flow direction shown in the water inlet channel 2101a in FIGS. 9 and 10 refers to the direction in which the water flow will at least flow under normal circumstances. When the water flow is out, part of the water flow in the water inlet channel 2101a will flow into the boiling water chamber in the opposite direction to the water flow shown in Figure 9 and Figure 10. In the inclined state, after the water flow fills the entire water inlet channel 2101a, a part of the water flow will flow into the first water boiling cavity 2101b. If the steam generator is in the inclined state shown in FIG. 10, the water flow will fill the entire water inlet channel 2101a. After that, a part of the water flow will flow into the second water boiling chamber 2101c.
一实施例中,请参阅图1至图3、图8,发热芯210包括芯体2101和与芯体2101的底端连接的端盖2102;芯体2101设置在外壳100中,端盖2102设置在外壳100外且与外壳100连接,温控器600与端盖2102背离进水通道2101a一侧的表面贴合。也就是说,端盖2102的部分区域形成进水 通道2101a对应的底壁,端盖2102上与温控器600贴合的位置就是进水通道2101a对应的底壁上的感温区。In one embodiment, please refer to FIG. 1 to FIG. 3 and FIG. 8 , the heating core 210 includes a core body 2101 and an end cap 2102 connected to the bottom end of the core body 2101 ; the core body 2101 is arranged in the housing 100 , and the end cap 2102 is arranged Outside the casing 100 and connected to the casing 100, the thermostat 600 is attached to the surface of the end cover 2102 on the side facing away from the water inlet channel 2101a. That is to say, a part of the end cover 2102 forms the bottom wall corresponding to the water inlet channel 2101a, and the position where the end cover 2102 fits with the thermostat 600 is the temperature sensing area on the bottom wall corresponding to the water inlet channel 2101a.
一实施例中,请参阅图4和图5,外壳100的底端面上可以设置第一密封圈300,端盖2102与外壳100之间通过第一密封圈300进行密封,以使外壳100中能够形成相对密闭的空间。In one embodiment, please refer to FIG. 4 and FIG. 5 , a first sealing ring 300 may be provided on the bottom end surface of the housing 100 , and the end cover 2102 and the housing 100 are sealed by the first sealing ring 300 , so that the housing 100 can be sealed with the first sealing ring 300 form a relatively closed space.
一实施例中,请参阅图1和图6,出汽口2102a设置在端盖2102上。也就是说,出汽口2102a位于蒸汽发生器的底部,此种设置位置适合于蒸汽拖把等需要直接将出汽口2102a对准地面等工作面的电器设备。In one embodiment, please refer to FIG. 1 and FIG. 6 , the steam outlet 2102 a is disposed on the end cover 2102 . That is to say, the steam outlet 2102a is located at the bottom of the steam generator, which is suitable for electrical equipment such as steam mops that need to directly align the steam outlet 2102a with a working surface such as the ground.
一些实施例中,出汽口2102a也可以设置在蒸汽发生器的顶部或侧面。In some embodiments, the steam outlet 2102a can also be provided on the top or side of the steam generator.
一实施例中,蒸汽发生器还包括保险丝,保险丝设置在端盖2102上且与发热管220串联。当温控器600失效而无法对感温区的温度进行正常检测时,保险丝可以对蒸汽发生器的整体温度进行检测,若检测到的温度超过安全温度,保险丝熔断且不可恢复,蒸汽发生器失效,也就是说,同时设置温控器600和保险丝可以对蒸汽发生器起到双重保护的作用,由此,可以提高蒸汽发生器的安全性。In one embodiment, the steam generator further includes a fuse, which is arranged on the end cover 2102 and is connected in series with the heating pipe 220 . When the thermostat 600 fails and cannot normally detect the temperature of the temperature sensing area, the fuse can detect the overall temperature of the steam generator.
