Example 1

A dispenser 1 shown in fig. 1 and 6 is used for containing liquid and guiding the liquid to a designated position, and comprises a distribution box 2, a sensing device 3 and a delivery pump 4 fixed outside the distribution box 2, wherein a chamber suitable for containing the liquid is arranged in the distribution box 2, and the delivery pump 4 is communicated with the chamber and delivers the liquid in the distribution box 2 to the outside of the distribution box 2; the cavity is divided into a liquid storage cavity 5 and a liquid level detection cavity 6 which are communicated with each other, and the height of the rear end face of the liquid level detection cavity 6 is higher than that of the rear end face of the liquid storage cavity 5 (the rear end face refers to the inner bottom face in the Z-axis direction in the appointed space direction, as shown in figure 10); a floater 7 is arranged in the liquid level detection cavity 6, and when the liquid level in the liquid level detection cavity 6 is lower than a specified height, the floater 7 triggers the sensing device 3.

The dispenser 1 in this embodiment is primarily intended for use in conjunction with a dishwasher, and therefore the liquid in the chamber is a brightener, and in other embodiments the liquid in the chamber may also be other washing stock.

The distribution box 2:

the distribution box 2 comprises a main shell 201, a panel 202 and a sealing cover 203, wherein the main shell 201 is of a box body structure with an opening at the front side, and the panel 202 covers the main shell 201 and forms a cavity with the main shell 201; a liquid filling port 2021 and a liquid outlet 2022 are arranged on the panel 202, the sealing cover 203 covers the liquid filling port 2021, the input end of the delivery pump 4 is communicated with the chamber, and the output end of the delivery pump 4 is communicated with the liquid outlet 2022. As shown in fig. 1 and 4, the panel 202 covers the front side of the main housing 201 and forms a chamber with the front side of the main housing 201 for storing brightener, the main housing 201 and the panel 202 are fixed by welding, the delivery pump 4 is mounted on the rear side of the main housing 201 by screws 14, the delivery pump 4 has a drain pipe 401 and a pipette 402 which are communicated with the chamber, the pipette 402 sucks liquid from the chamber, and the drain pipe 401 outputs the liquid sucked into the pump chamber and discharges the liquid from the liquid outlet 2022 to the outside of the distribution box 2. The sealing cover 203 is used for sealing or opening the liquid storage chamber 5 so as to allow a user to add liquid into the liquid storage chamber 5 from the liquid adding port 2021. The liquid inlet 2021 is located at the upper part of the panel 202, and the liquid outlet 2022 is located at the lower part of the panel 202. When the dispenser 1 is mounted on the door 12 of the dishwasher, the rear side of the main housing 201 is attached to the door 12, and when the door 12 is closed, the filling port 2021 is located above the liquid outlet 2022, and the liquid can be transported from top to bottom along the pipeline under the action of gravity.

To ensure the sealing effect, the outer peripheries of the panel 202 and the main housing 201 are provided with a sealing ring 15.

The sensing device 3 and the float 7 are mounted on the main housing 201, and are matched with each other to monitor the liquid level in the liquid level detection chamber 6. Liquid level detection chamber 6 is close to the left side or the right side setting of cavity, that is to say liquid level detection chamber 6 and stock solution chamber 5 are located the both sides of cavity respectively, can avoid liquid level detection chamber 6 to set up inside stock solution chamber 5 like this, and the liquid that leads to in the stock solution chamber 5 when door 12 closes spatters in liquid level detection chamber 6. In this embodiment, the liquid level detection chamber 6 is disposed near the left side of the chamber, and as shown in fig. 6, the liquid level detection chamber 6 is located at the lower right side of the chamber.

The area of cavity in the distributor box 2 in the XOY plane is great, the utility model discloses set up stock solution chamber 5 and liquid level detection chamber 6 in the cavity, stock solution chamber 5 is used for storing liquid, delivery pump 4 absorbs liquid from stock solution chamber 5, the liquid level situation in liquid level detection chamber 6 mainly used monitoring stock solution chamber 5, the interior bottom surface area of liquid level monitoring chamber edge Y to is less, when door 12 closes, when the XOY plane becomes vertical position gradually, even liquid in the liquid level detection chamber 6 less also can have higher liquid level, be favorable to passing through float 7 monitoring liquid level more accurately.

It should be noted that the sensing device 3 can be triggered only when the door 12 is closed, and the sensing device 3 does not monitor the liquid level in the liquid level detection chamber 6 when the door 12 is opened, and this function can be realized by the controller linking the switch of the door 12 and the switch of the sensing device 3 with each other, which is well known to those skilled in the art and will not be described in detail herein.

The utility model discloses a theory of operation does: when the door 12 of the dishwasher is horizontally opened, the XOY surface of the distributor 1 is in a horizontal position, the liquid in the distribution box 2 is flatly spread on the Z-direction inner bottom surface of the liquid storage cavity 5, if the liquid in the liquid storage cavity 5 is less than a certain degree, the liquid in the liquid level detection cavity 6 cannot be stored in the cavity because the inner bottom surface is higher. When the dishwasher door 12 is closed again, i.e. the XOY plane gradually changes to a vertical orientation, there is still no liquid in the liquid level detection chamber 6 because there is no liquid accumulation on the bottom surface.

A floater 7 is arranged in the liquid level detection cavity 6, and a magnetic element is arranged in the floater 7. The float 7 is less dense than the liquid stored in the dispenser 1 and floats when the float 7 is submerged in liquid (figure 7). As can be seen from fig. 6 and 7, when the liquid in the liquid storage chamber 5 is reduced to a certain extent (fig. 6), the liquid level detection chamber 6 has no liquid or very little liquid, and at this time, the float 7 falls down, and triggers the sensing device 3 (illustrated as a reed pipe device), thereby generating an alarm of insufficient liquid storage. When the liquid in the liquid storage cavity 5 is sufficient (fig. 7), the liquid level detection cavity 6 also stores the liquid, the floater 7 floats up, the sensing device 3 cannot be triggered, and the dispenser 1 normally puts in the liquid.

For example, when the XOY surface of the dispenser 1 is in a horizontal position and there is no liquid in the liquid level detection chamber 6, that is, the height of the liquid level is smaller than the height difference between the liquid level detection chamber 6 and the liquid storage chamber 5 along the Z-direction inner bottom surface, it indicates that the liquid level in the liquid storage chamber 5 is too low, and when the door 12 is closed, the float 7 will trigger the sensing device 3 to give an alarm to remind feeding; when the XOY surface of the dispenser 1 is in the horizontal position and there is liquid in the liquid level detection chamber 6, that is, the height of the liquid level is greater than the height difference between the liquid level detection chamber 6 and the liquid storage chamber 5 along the Z-direction inner bottom surface, it indicates that the liquid in the liquid storage chamber 5 is enough for one-time charging use, and when the machine door 12 is closed, the float 7 floats and does not trigger the sensing device 3. Therefore, whether the liquid level reaches the standard is mainly distinguished through the height difference of the liquid level detection cavity 6 and the liquid storage cavity 5 along the Z-direction inner bottom surface. In order to prevent a part of the liquid in the liquid storage chamber 5 from entering the liquid level detection chamber 6 when the door 12 is closed, the sensing device 3 may be triggered after the float 7 floats to a certain height when the door 12 is closed.

Preferably, the height difference between the height of the rear end face of the liquid level detection cavity 6 and the height of the rear end face of the liquid storage cavity 5 is 2-5 mm. When the Z of stock solution chamber 5 to inside bottom surface area great, and the dish washer single volume of puting in is less, the difference in height of the rear end face height of liquid level detection chamber 6 and the rear end face height of stock solution chamber 5 can set up to be less, for example set up to 2mm, on the contrary, when the Z of stock solution chamber 5 to inside bottom surface area less, and the dish washer single volume of puting in is great, the height difference in height of the rear end face height of liquid level detection chamber 6 and the rear end face height of stock solution chamber 5 can set up to be great, for example set up to 5 mm.

Example 2

In embodiment 1, liquid level detection chamber 6 can communicate with stock solution chamber 5 through the left side opening, but the left side opening is if too big, when door 12 is closed, liquid in the stock solution chamber 5 can get into in the liquid level detection chamber 6, influence monitoring results, the left side opening is if the undersize, can cause liquid flow too slowly, in this embodiment, as shown in fig. 6, liquid level detection chamber 6 is open-top's box body structure, liquid level detection chamber 6 is through this opening and stock solution chamber 5 intercommunication, the top in liquid level detection chamber 6 is equipped with and just to the long type chamber 8 of intercommunication with liquid level detection chamber 6, the rear end face height of long type chamber 8 equals the rear end face height in liquid level detection chamber 6.

When the liquid in the liquid storage cavity 5 is not much but enough to be used for one time, after the door 12 of the dish washing machine is opened, the liquid which is flatly spread on the long cavity flows to the liquid level detection cavity 6 when the door 12 of the dish washing machine is closed, and the floater 7 floats. The liquid level detection cavity 6 is opposite to the long cavity 8, which means that the areas of the long cavity 8 and the liquid level detection cavity 6 on the XOZ surface are similar and correspond to each other.

The reason why the inner bottom surface of the long cavity 8 is flush with the inner bottom surface of the liquid level detection cavity 6 is that: if the inner bottom surface of the long cavity 8 is higher than the inner bottom surface of the liquid level detection cavity 6, the total capacity of the liquid storage cavity 5 is reduced; when the inner bottom surface of the long cavity 8 is lower than the inner bottom surface of the liquid level detection cavity 6, when the door 12 of the dishwasher is horizontally opened, if the inner bottom surface of the liquid level detection cavity 6 has no liquid, the liquid in the long cavity 8 may be stored, and the stored liquid will flow to the liquid level detection cavity 6 when the door 12 is closed, so that the floater 7 is floated by mistake.

Example 3

On the basis of embodiment 2, as shown in fig. 5, a baffle 9 is disposed at an opening of the liquid level detection chamber 6, and the baffle 9 is disposed between the liquid storage chamber 5 and the liquid level detection chamber 6 and extends from the liquid level detection chamber 6 to the long cavity 8. The baffle 9 can better let the liquid in the elongated cavity 8 enter the liquid level detection cavity 6 and is not easily shunted by the liquid storage cavity 5.

Example 3

On the basis of embodiment 1 or embodiment 2 or embodiment 3, as shown in fig. 6 and 7, the liquid storage cavity 5 is embedded with an induction device installation groove 10, the induction device installation groove 10 is not communicated with the liquid storage cavity 5, and the induction device installation groove 10 is arranged adjacent to the liquid level detection cavity 6.

Induction system mounting groove 10 does not communicate with stock solution chamber 5, can avoid liquid to get into induction system mounting groove 10, causes induction system 3 malfunctioning. The induction device mounting groove 10 is arranged adjacent to the liquid level detection cavity 6, so that the floater 7 in the liquid level detection cavity 6 can be conveniently induced. In addition, the embedded sensing device mounting groove 10 does not occupy the external space of the distributor 1, and the whole structure is more compact.

Preferably, as shown in fig. 3, a waterproof vent plug 13 is further disposed on the panel 202, the waterproof vent plug 13 is mounted in an upper region of the front surface of the panel 202, and when a negative pressure occurs in the reservoir 5, air can enter the reservoir 5 through the waterproof vent plug 13.
