At present, the methods for detecting the liquid shortage of household appliances comprise the following steps:

scheme 1: the Hall flowmeter is characterized in that a specific implementation method is that when a water pump works, whether liquid in a liquid storage tank is drained or not is judged by detecting whether signals of a Hall sensor exist or not; the advantage of this scheme is that can the testing result is more reliable, but this scheme water pump meeting idle running when the starvation, can not detect the liquid reserve tank and whether install in place and the price is higher.

Scheme 2: the resistance type detection method is characterized in that whether liquid exists in the liquid storage tank or not is judged by detecting the resistance between 2 pieces of metal. The scheme is simple and reliable, but the metal sheet needs to be in contact with liquid, so that the power supply is required to be an isolation scheme, the metal sheet cannot rust, and the scheme also cannot detect whether the liquid storage tank is installed in place;

scheme 3: according to the detection method for the reed pipe and the water level floater, when liquid exists in the liquid storage tank, the water level floater rises, and the magnet in the floater can lead the reed pipe to be connected, so that whether the liquid exists or not is judged. This solution is low cost, but not highly reliable. And a plurality of reed pipes are internally short-circuited, so that the product fails.

The three liquid shortage detection methods are not very reliable, and can not accurately detect whether the liquid storage tank can normally supply liquid to the equipment body, which may cause damage to the machine.

Based on this, the present application provides a household electrical appliance 100, the household electrical appliance 100 includes an appliance body 1 and a liquid storage tank 2, wherein the appliance body 1 is provided with a first circuit element 3 and a second circuit element 5 which are connected in series, and a water level trigger 4 and a positioning detection element 6 which are respectively used for triggering the first circuit element 3 and the second circuit element 5 are arranged in the liquid storage tank 2, so that the household electrical appliance 100 can perform liquid shortage detection through the cooperation of the first circuit element 3 and the water level trigger 4, and can also detect whether the liquid storage tank 2 is installed in place through the cooperation of the positioning detection element 6 and the second circuit element 5; and the first circuit component 3 and the second circuit component 5 are connected in series, that is, the liquid storage tank 2 is not installed in place or is short of liquid, that is, one of the first circuit component 3 and the second circuit component 5 is disconnected, and the detection loop formed by the first circuit component 3 and the second circuit component 5 is disconnected, so that the household appliance 100 does not need to supply power to the other one of the first circuit component 3 and the second circuit component 5, and can save the energy consumption of the household appliance 100, and the household appliance 100 can determine that the liquid storage tank 2 is not installed in place or is short of liquid based on the disconnection of the detection loop formed by the first circuit component 3 and the second circuit component 5, and can determine that the liquid storage tank 2 cannot normally supply liquid to the appliance body 1, so that the household appliance 100 can accurately determine whether the liquid storage tank 2 can normally supply liquid to the appliance body 1, and avoid that the household appliance 100 normally operates under the condition that the liquid storage tank 2 cannot normally supply liquid to the appliance body 1 The device 100 is broken.

As shown in fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a home appliance 100 according to the present application. The household appliance 100 may be an instant hot water machine, a coffee machine, a juice extractor, or the like.

The home appliance 100 includes an appliance body 1 and a liquid tank 2. The apparatus body 1 is formed with a mounting wall 11, and the liquid storage tank 2 is detachably mounted to the mounting wall 11.

The liquid storage tank 2 is used for containing liquid such as water or alcohol.

The liquid storage tank 2 may further be provided with a liquid outlet (not shown), through which the liquid storage tank 2 communicates with the apparatus body 1, so that the liquid storage tank 2 provides liquid to the apparatus body 1 through the liquid outlet, and the apparatus body 1 may process the liquid (for example, atomize and discharge the liquid to humidify the surrounding environment, or may heat the liquid).

The liquid storage tank 2 may further be provided with a liquid inlet (not shown) for filling liquid, so that a user can fill the liquid storage tank 2 with liquid through the liquid inlet.

In this embodiment, the inlet sets up in 2 roof of liquid reserve tank, and the liquid outlet sets up in 2 diapire of liquid reserve tank. Of course, the arrangement positions of the liquid inlet and the liquid outlet are not limited, for example, the liquid inlet may be arranged on the bottom wall of the liquid storage tank 2, and the liquid outlet may be arranged on the side wall of the liquid storage tank 2.

In addition, the apparatus body 1 is provided with a first circuit element 3, and the liquid storage tank 2 may be provided with a water level trigger 4 for triggering the first circuit element 3.

Wherein, first circuit element 3 and water level trigger 4 cooperation can be used to the scarce liquid of liquid reserve tank 2 and detect, and when the liquid level in the liquid reserve tank 2 was less than preset high (even for when not having liquid in the liquid reserve tank 2), water level trigger 4 triggered first circuit element 3, and first circuit element 3's state changes, and whether household electrical appliances 100 can confirm the liquid reserve tank 2 in the scarce liquid based on first circuit element 3's state change condition like this.

The first circuit element 3 and the reservoir tank 2 may be provided on opposite surfaces of the mounting wall 11, respectively. For example, the reservoir tank 2 may be provided on an upper surface of the mounting wall 11, and the first circuit element 3 may be provided on a lower surface of the mounting wall 11. For another example, the reservoir tank 2 may be provided on a left surface of the mounting wall 11, and the first circuit element 3 may be provided on a right surface of the mounting wall 11.

In this embodiment, the first circuit component 3 may be a second magnetic switch (for example, a reed switch), and the water level trigger 4 may be a magnetic float, so that when the liquid level in the liquid storage tank 2 is lowered to a level lower than a preset height, the second magnetic switch changes from on to off due to sensing the water level trigger 4 floating on the liquid level, so that the household electrical appliance 100 may confirm that the liquid storage tank 2 is short of liquid when confirming that the second magnetic switch is off.

Wherein, can be equipped with limit structure in the liquid reserve tank 2, this limit structure is used for letting the float only to remove along the direction of height H of liquid reserve tank 2 for the float does not take place the displacement in the horizontal direction. That is, assuming that the float is disposed directly above the first circuit element 3, the limit structure may cause the float to be distant from or close to the first circuit element 3 only directly above the first circuit element 3, so that the distance between the float and the second magnetic switch is only related to the liquid level, i.e., the liquid level may be decreased or increased by the same amount as the distance between the float and the second magnetic switch is decreased or increased.

In addition, a height limiting member for preventing the float from continuing to rise when the float rises to the second height, that is, a height limiting member for making a distance between the float and the second magnetic switch within a preset range to limit the float within the liquid storage tank 2, may be further provided within the liquid storage tank 2.

Wherein, limit structure and/or limit for height piece can form with liquid reserve tank 2 integrated into one piece.

Further, when the liquid storage tank 2 is disposed on the upper surface of the mounting wall 11 and the first circuit element 3 is disposed on the lower surface of the mounting wall 11, the water level trigger 4 may be disposed directly above the first circuit element 3, such that when the liquid level in the liquid storage tank 2 is within the second height range, the liquid level may be decreased or increased by the same amount as the distance between the first circuit element 3 and the water level trigger 4 is decreased or increased, thereby avoiding "when the horizontal distance between the first circuit element 3 and the water level trigger 4 is greater than the upper limit of the distance that the first circuit element 3 can sense the water level trigger 4", the situation that the first circuit element 3 cannot sense the water level trigger 4 even when the water level trigger 4 reaches the bottom wall of the liquid storage tank 2, so as to improve the accuracy of the liquid shortage detection of the first circuit element 3 and the water level trigger 4. The second height can be larger than the preset height, namely the water level trigger 4 is required to be allowed to rise to the preset height along with the liquid level, so that the situation that the second magnetic switch can sense the floater no matter how high the liquid level is caused by the fact that the maximum rising height of the water level trigger 4 is smaller than or equal to the preset height is avoided. The second height may even be the height of the reservoir 2, i.e. the float may rise as the liquid level rises, no matter how much the liquid level rises.

In other embodiments, the first circuit element 3 may be a metal sheet disposed on the device body 1, and the water level trigger 4 is a metal sheet fixedly disposed on the liquid storage tank 2, wherein the water level trigger 4 is also disposed in a detection loop formed by the first circuit element 3 and the second circuit element 5, so that when the liquid level in the liquid storage tank 2 is reduced to a level lower than a certain level (for example, a preset height), air enters between the two metal sheets, the resistance between the two metal sheets is increased to a maximum value, the detection loop formed by the first circuit element 3 and the second circuit element 5 is disconnected, and thus the household electrical appliance 100 can know that the liquid storage tank 2 in the household electrical appliance 100 is not mounted in place or the liquid storage tank 2 is short of liquid when confirming the disconnection of the detection loop.

In addition, the apparatus body 1 may further be provided with a second circuit element 5, and a positioning detection element 6 for triggering the second circuit element 5 may be provided in the liquid storage tank 2.

The second circuit element 5 and the positioning detection element 6 are matched to detect whether the liquid storage tank 2 is installed in place, if the liquid storage tank 2 is installed in place, the positioning detection element 6 triggers the second circuit element 5, the state of the second circuit element 5 changes, and therefore the household appliance 100 can determine whether the liquid storage tank 2 is installed in place based on the state change condition of the second circuit element 5. Here, the case where the liquid storage tank 2 is mounted in place may be understood as the case where the liquid storage tank 2 is mounted at a predetermined position of the mounting wall 11, or may be understood as the case where the liquid storage tank 2 is mounted at a position where liquid in the liquid storage tank can be normally supplied to the apparatus body 1.

The second circuit element 5 and the reservoir 2 may be disposed on opposite sides of the mounting wall 11, respectively. For example, the reservoir tank 2 may be provided on an upper surface of the mounting wall 11, and the second circuit member 5 may be provided on a lower surface of the mounting wall 11. For another example, the reservoir tank 2 may be provided on a left surface of the mounting wall 11, and the second circuit element 5 may be provided on a right surface of the mounting wall 11.

In addition, the second circuit element 5 may be located on the same side of the mounting wall 11 as the first circuit element 3. For example, the second circuit element 5 and the first circuit element 3 are both located below the mounting wall 11. For another example, the second circuit element 5 and the first circuit element 3 are both located on the left side of the mounting wall 11. In other embodiments, the second circuit element 5 may be located on a different side of the mounting wall 11 than the first circuit element 3.

Preferably, location detecting element 6 can set up in the adjacent position of the liquid outlet of liquid reserve tank 2 to when further guaranteeing that location detecting element 6 is located the position that can trigger second circuit component 5, the liquid outlet of liquid reserve tank 2 just in time aims at the inlet of equipment body 1, and liquid reserve tank 2 just in time installs in place when can further guaranteeing second circuit component 5 disconnection.

In this embodiment, the second circuit component 5 may be a micro switch, and the positioning detection component 6 is a push rod, so that when the liquid storage tank 2 is mounted on the mounting wall 11, the push rod passes through the mounting wall 11 and presses the micro switch to change the switch state of the micro switch, so that the household appliance 100 can confirm whether the liquid storage tank 2 is mounted in place based on the state change condition of the second circuit component 5. The ram may be connected to the side of the tank 2 adjacent the mounting wall 11.

Wherein the second circuit element 5 is exposable to the mounting wall 11 so that the position detection element 6 can be pressed directly to the second circuit element 5 to change the state of the second circuit element 5. Specifically, the reservoir tank 2 and the second circuit member 5 may be disposed on opposite sides of the mounting wall 11, and the mounting wall 11 may be formed with a through-hole for exposing the second circuit member 5 to the mounting wall 11, so that the position detecting member 6 on the reservoir tank 2 may be directly pressed to the second circuit member 5 through the through-hole of the mounting wall 11.

In other embodiments, the second circuit element 5 may be a first magnetic switch, the positioning detection element 6 may be a magnetic member fixedly disposed in the liquid storage tank 2, and when the liquid storage tank 2 is installed in place, the second circuit element 5 can just sense the positioning detection element 6, so that the state of the second circuit element 5 changes, and the household appliance 100 can determine whether the liquid storage tank 2 is installed in place according to the state of the second circuit element 5. Specifically, when liquid reserve tank 2 installed in place, the distance between second circuit component 5 and the location detecting element 6 just in time can be sensed the biggest limit distance of location detecting element 6 for second circuit component 5, can avoid like this "second circuit component 5 can sense the great the biggest limit distance of location detecting element 6" lead to the condition that liquid reserve tank 2 also can sense location detecting element 6 when not installing in place "like this, make only when liquid reserve tank 2 installs in place second circuit component 5 can sense location detecting element 6, in order to improve the accuracy that liquid reserve tank 2 installation conditions detected.

Alternatively, as shown in fig. 2, the first circuit element 3 and the second circuit element 5 are connected in series. Like this when the liquid reserve tank 2 is installed in place, location detecting element 6 triggers second circuit component 5, and second circuit component 5 switches on, and first circuit component 3 can respond to water level trigger 4 this moment: if the first circuit component 3 does not sense the water level trigger 4 (i.e. no liquid is in the liquid storage tank 2), the first circuit component 3 is conducted; if the first circuit element 3 senses the water level trigger 4 (i.e. the liquid is lacking in the liquid storage tank 2), the first circuit element 3 is disconnected, and thus the detection circuit formed by the first circuit element 3 and the second circuit element 5 is disconnected. When the liquid storage tank 2 is not installed in place, the positioning detection element 6 cannot trigger the second circuit element 5, the second circuit element 5 is disconnected, the detection circuit formed by the first circuit element 3 and the second circuit element 5 is disconnected, and at the moment, the first circuit element 3 cannot sense the water level trigger 4. In summary, as long as the liquid storage tank 2 cannot supply liquid to the device body 1, that is, the liquid storage tank 2 is not installed in place or is short of liquid, that is, one of the first circuit element 3 and the second circuit element 5 is disconnected, the detection circuit formed by the first circuit element 3 and the second circuit element 5 is disconnected, so that the household appliance 100 does not need to supply power to the other one of the first circuit element 3 and the second circuit element 5, energy consumption of the household appliance 100 can be saved, and the household appliance 100 can determine that the liquid storage tank 2 is not installed in place or is short of liquid based on the disconnection of the detection circuit formed by the first circuit element 3 and the second circuit element 5, that is, it can be determined that the liquid storage tank 2 cannot normally supply liquid to the device body 1, so that the household appliance 100 of the present application can accurately determine whether the liquid storage tank 2 can normally supply liquid to the device body 1.

In addition, the home device 100 may further include a controller (not shown) coupled to the first circuit element 3 and the second circuit element 5, so that the home device 100 confirms whether the detection loop formed by the first circuit element 3 and the second circuit element 5 is disconnected through the controller. And the controller may be configured to confirm that the liquid storage tank 2 cannot normally supply the liquid to the apparatus body 1 due to a liquid shortage or a non-installation in place when it is confirmed that the detection circuit constituted by the first circuit element 3 and the second circuit element 5 is disconnected, and then control the home appliance 100 to stop operating or give an alarm to protect the home appliance 100.

Further, the household electrical appliance 100 may further include an alarm (not shown), which is electrically connected to the controller. The controller is configured to control the alarm to send an alarm signal when the first circuit element 3 and/or the second circuit element 5 are disconnected, that is, when the liquid storage tank 2 cannot normally supply liquid to the apparatus body 1 due to liquid shortage or non-installation in place, so that a user can timely know that the problem that the liquid storage tank 2 cannot normally supply liquid to the apparatus body 1 occurs and timely solve the problem.
