The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring first to fig. 1, a detergent box according to the present invention is schematically illustrated when being mounted to a front panel. As shown in fig. 1, the front panel 101 of the washing device of the present invention is provided with a casing 102, in the preferred embodiment, in order to add detergent and softener separately, two detergent boxes are provided in the casing 102, that is, two box bodies 1 are provided in the casing 102, and the cold water supply pipeline of the washing device is communicated to the washing space inside the washing device through the detergent boxes, so that the detergent in the detergent boxes can be flushed to the washing space through water flow. It should be noted that, the present invention does not limit the specific structure of the washing device and the specific installation position of the detergent box, and the technician can set the specific structure according to the actual use requirement.
Next, referring to fig. 2 to 4, wherein fig. 2 is a schematic view of an overall structure of the detergent box of the present invention; fig. 3 is a first internal structural view of the detergent box of the present invention, in which a stopper member is shown in a state of being assembled; fig. 4 is a second internal structure diagram of the detergent box of the present invention, in which the assembled stopping member is shown. The detergent box comprises a box body 1 and a liquid level detection assembly arranged in the box body 1, and by taking the detergent in the box body 1 as an example, the liquid level detection assembly can detect the liquid level height of the detergent in the box body 1 so as to remind a user of replenishing the detergent in the box body 1 when the quantity of the detergent is less. Specifically, a vertical guide groove 2 is provided in the box body 1. The liquid level detecting assembly includes a float 3 and a float sensing member (not shown). The floating ball 3 is freely accommodated in the vertical guide groove 2, and when the amount of the detergent stored in the box body 1 changes, the floating ball 3 can float up and down along the vertical guide groove 2 along with the increase and decrease of the liquid level height of the detergent. The floating ball sensing member can sense the height position of the floating ball 3 so as to determine the liquid level height of the detergent through the height position of the floating ball 3. The floating ball sensing component is arranged at the bottom of the vertical guide groove 2, so that the sensing range of the floating ball sensing component is diffused from the bottom of the vertical guide groove 2 to the upper part of the groove. When the amount of the detergent in the box body 1 is gradually reduced, the liquid level of the detergent is gradually reduced, and the floating ball 3 gradually approaches the center of the sensing range of the floating ball sensing component and goes deep into the floating ball sensing component. When the position of the floating ball 3 is lowered to the set lowest liquid level, the detergent storage early warning of the washing equipment is triggered, and therefore a detergent adding prompt is sent to a user. Preferably, the utility model discloses a detergent box still includes stop component 4, this stop component 4 sets up in above-mentioned vertical guide slot 2 to it sets up to the response within range that can restrict the removal scope of floater 3 at floater response component, so that avoid in the box body 1 detergent stock enough, make floater 3's floating position surpass floater response component's response scope when the detergent liquid level is higher, prevent that the liquid level detection component is difficult to accurately distinguish floater response component fault conditions (floater response component can't respond to the position of floater 3 because of the trouble) and the condition that the detergent liquid level height is higher than floater response component's response scope.
Further, the limiting member 4 is a limiting plate disposed on the top of the vertical guide slot 2. At least one part of the limiting plate extends to the inside of the vertical guide groove 2 so as to cut off the moving route of the floating ball 3, so that the floating ball 3 cannot move to the upper part far away from the floating ball sensing component beyond the limiting plate, and the floating ball 3 is always blocked in the sensing range of the floating ball sensing component. In this case, when the liquid level of the detergent in the box body 1 is higher than the blocking position of the limiting plate (the blocking portion of the limiting plate, such as the lower end of the limiting plate in the figure), the floating ball 3 floats due to the buoyancy to abut against the bottom side of the blocking position of the limiting plate and is still in the sensing range. At this time, before the liquid level height of the detergent is lowered to the lowest point of the blocking position of the limiting plate, the liquid level of the detergent is obviously always higher than the set lowest liquid level, and the detergent stock is always in a sufficient state. When the liquid level height of the detergent is gradually reduced and is positioned below the limiting plate, the floating ball 3 leaves the limiting plate along with the reduction of the liquid level height of the detergent and gradually moves downwards, the liquid level height of the detergent is gradually close to the lowest liquid level, and in the process, the floating ball sensing component can determine the liquid level change condition of the detergent according to the change of the floating height of the floating ball 3.
As shown in fig. 3 and 4, further, a limit plate is vertically disposed in the vertical guide groove 2. Compare with the limiting plate of slope setting, the limiting plate of vertical setting is littleer to the hindrance effect when the detergent flows, can not cause the detergent liquid level change in the vertical guide slot 2 to postpone the condition. As a preferable example, the limit plate is vertically disposed at a middle position of the top of the vertical guide groove 2.
Preferably, the liquid passing structure 41 is disposed on the limiting plate. As can be seen from fig. 2 to 4, the liquid passing structure 41 is a through structure provided on the stopper plate. Due to the fact that part of the detergent has certain viscosity (such as washing liquid) and flows relatively slowly, the penetrating structure enables the detergent on the two sides of the limiting plate to be in a communicated state, and the condition that the detergent on the two sides of the plate body of the limiting plate flows unevenly is avoided.
In the above description, it should be noted that, although the above-described stopper member 4 is described in conjunction with a stopper plate, the shape of the stopper member 4 is not limited. The shape of the limiting component 4 is only required to be set to have a blocking effect on the floating ball 3 without influencing the normal lifting of the detergent in the vertical guide groove 2. For example, the stopper member 4 may be a columnar member extending from a groove wall of the vertical guide groove 2 in the groove inner direction. In addition, under the condition of not influencing the normal flowing of the detergent and the limiting effect of the limiting component 4 on the floating ball 3, the arrangement position of the limiting component 4 can be improved by the technical personnel in the field.
Continuing to refer to fig. 3 and 4, in order to increase the convenience of disassembly and assembly during maintenance or installation of the floating ball 3 or the floating ball sensing member and reduce the difficulty of production and processing of the box body 1, the limiting plate is detachably connected to the vertical guide groove 2, so that the problem that the floating ball 3 or the floating ball sensing member is difficult to take and place from the inside of the vertical guide groove 2 when the limiting plate and the vertical guide groove 2 are integrally arranged is avoided.
Further, the limiting plate is connected to the vertical guide groove 2 in a clamping manner. Specifically, a clamping groove 21 is arranged in the vertical guide groove 2, and the limiting plate is clamped on the vertical guide groove 2 through the clamping groove 21. Through the above-mentioned joint setting for can not produce independent connecting piece (like the screw) between limiting plate and the 2 vertical guide slots, the condition that the connecting piece loses appears when avoiding limiting plate and 2 dismouting of vertical guide slot.
In the above embodiment, the limit plate is fixedly connected to the vertical guide groove 2 by being inserted and fixed into the slot 21 at the side. However, under the condition that the assembly space allows, the clamping groove 21 can be further arranged on the limiting plate, and the inner wall of the vertical guide groove 2 can be provided with the clamping end matched with the inner wall of the limiting plate, so that the limiting plate can be clamped in the clamping groove 21 to complete the fixed assembly work of the limiting plate in the clamping end. Of course, the clamping structure combination between the limiting plate and the vertical guide groove 2 is not limited to the above example, as long as the selected clamping structure combination can meet the requirement of detachable connection between the limiting plate and the vertical guide groove 2. For example, a combination of snap-fit structures such as a snap-fit groove or a tongue-and-claw structure may be adopted.
As shown in fig. 3 and 4, the engaging groove 21 preferably has a length so that a longer engaging area is formed between the engaging groove 21 and the position limiting plate, thereby increasing the fixing reliability of the position limiting plate. Under this situation, above-mentioned draw-in groove 21 is along vertical setting, and the top of draw-in groove 21 is provided with opening 211 to the curb plate of limiting plate can slide in and the card is arranged in draw-in groove 21 through this opening 211, makes the installer aim at the back with limiting plate and opening 211 as long as can accomplish the fixed work of limiting plate through pushing the action, only need during the dismantlement with the limiting plate follow draw-in groove 21 take can, thereby further promote the convenience of limiting plate dismouting.
In a particular embodiment, the vertical guide 2 is integral with the box 1. In particular, as can be seen from fig. 2 and 3, the vertical guide groove 2 is provided close to at least one box wall of the box body 1, so that the arrangement space within the box body 1 can be optimized by replacing the groove wall of the vertical guide groove 2 by the box wall of the box body 1. Illustratively, the case 1 is a narrow and tall rectangular case. According to the orientation of fig. 3, the vertical guide groove 2 is arranged at the rightmost side of the box body 1, and the front side wall, the right side wall and the rear side wall of the box body 1 can form three groove walls of the vertical guide groove 2. The position that is close to the right side extends between the preceding, the back lateral wall of box body 1 has the riser, and this riser encloses into vertical banding vertical guide slot 2 with the preceding lateral wall, the right side wall and the back lateral wall of box body 1 jointly (in order to guarantee that the detergent in the box body 1 well communicates with the detergent in the vertical guide slot 2, the liquid level change state is unanimous, this riser sets up between the preceding, the back lateral wall of box body 1 with non-confined mode). When the floating ball 3 is accommodated in the vertical guide groove 2, the vertical plate can always limit the floating ball 3 at the right side of the box body 1. The clamping groove 21 is directly formed in the inner side of the rear side wall or the front side wall of the box body 1, so that the limiting plate can be inserted into and clamped to the top of the vertical guide groove 2, and the floating ball 3 is limited to float up and down at the middle lower part of the right side of the box body 1.
More specifically, as a preferred embodiment, the liquid detection assembly is a reed liquid level sensor. The inside of floater 3 is provided with magnetic component, and floater response component is the dry reed who sets up in box body 1 bottom. The magnetic member inside the float 3 is capable of generating a magnetic field. When the floating position of the floating ball 3 is changed, the position of the dry reed in the magnetic field is changed, the strength of the induced magnetic force is changed, and the position change condition of the floating ball 3 is determined according to the magnetic force change condition, so that the current liquid level height of the detergent is judged.
To sum up, the detergent box of the utility model is internally provided with a liquid level detection component and a limiting component 4; the liquid level detection assembly comprises a floating ball 3 accommodated in the vertical guide groove 2 and a floating ball induction component arranged at the bottom of the vertical guide groove 2; the limiting component 4 is used for limiting the moving range of the floating ball 3 within the sensing range of the floating ball sensing component. Through the arrangement, the floating ball sensing component can sense the floating ball 3 all the time, so that the situation that the floating ball 3 floats too high due to overhigh detergent liquid level and exceeds the sensing range of the floating ball sensing component is effectively avoided, the situation that the floating ball 3 cannot be sensed due to the fact that the floating ball sensing component is broken down by the liquid level detection component is judged to be the situation that the floating position of the floating ball 3 is high and the detergent stock is enough is effectively avoided, and the misjudgment rate of detergent liquid level monitoring is reduced.
