Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a leveling device and a dishwasher. Background Art

[0002] Built-in dishwashers are installed into the user's cabinet by a professional installer. To ensure the dishwasher is installed at the correct level within the cabinet, the installer needs to manually adjust the height of the feet. The levelness of the installation is limited by the installer's skill level, which may result in the dishwasher tilting forward / backward or side / to side after installation.

[0003] Tilting a dishwasher forward or backward can cause abnormal water accumulation in the drum. For example, tilting the dishwasher forward may cause water to pool at the front door, leading to leakage through the door gaps. Tilting it backward may cause water to pool at the bottom rear of the drum, reducing the water intake of the front-mounted heating pump and thus lowering its operating power, affecting cleaning performance. Similarly, tilting the dishwasher left or right will also affect the water intake efficiency of the heating pump, reducing its operating power and impacting cleaning results. Utility Model Content

[0004] The purpose of this application is to provide a leveling device and a dishwasher for adjusting the level of the washing heating pump so that the level of the washing water collected at the bottom of the inner tank and entering the washing heating pump can be kept horizontal, thereby ensuring the normal operation of the washing heating pump.

[0005] This application provides a leveling device for cleaning equipment. The cleaning equipment includes an inner tank, and the outlet of the inner tank is provided with a manifold and a washing heating pump. The washing heating pump is installed on the manifold. The leveling device includes a tilt sensor and multiple adjusting feet.

[0006] The tilt sensor is installed on the manifold to measure the tilt angle of the washing heating pump relative to the horizontal plane;

[0007] Multiple adjustable feet are installed at the bottom of the washing equipment and are spaced apart. The tilt sensor is communicatively connected to the multiple adjustable feet so that at least one of the adjustable feet can extend or retract, thereby adjusting the level of the washing heating pump.

[0008] In the above technical solution, the busbar further includes a busbar section and a mounting section;

[0009] The confluence unit is installed at the water outlet of the inner tank. The confluence unit is provided with a confluence groove to collect the washing water flowing out of the water outlet. The confluence groove is provided with a connecting hole, which is connected to the washing heating pump.

[0010] The mounting section includes a first mounting section and a second mounting section, which are arranged adjacent to each other. The tilt sensor is mounted on the first mounting section, and the washing heating pump is mounted on the second mounting section, so that the tilt sensor and the washing heating pump are installed in parallel or on the same plane.

[0011] In the above technical solution, the washing heating pump is further installed at the bottom of the second mounting part;

[0012] The bottom of the first mounting part is provided with a mounting groove, which is adapted to the tilt sensor so that the tilt sensor can be detachably installed in the mounting groove.

[0013] In the above technical solution, the bottom of the mounting groove is provided with three positioning protrusions, and the three positioning protrusions are evenly arranged to form a plane for positioning the tilt sensor.

[0014] In the above technical solution, the bottom of the mounting groove is provided with a snap-fit ​​hole, and the bottom of the tilt sensor is provided with a first buckle, which snaps into the snap-fit ​​hole.

[0015] And / or the wall of the mounting groove is provided with a locking block, and the side of the tilt sensor is provided with a corresponding second buckle. The second buckle has a locking groove. The tilt sensor is rotatably mounted in the mounting groove so that the locking block is locked into the corresponding locking groove of the second buckle.

[0016] In the above technical solution, when the bottom and side of the tilt sensor are both engaged with the mounting groove, the engagement hole is a circular hole, the first buckle includes multiple engagement segments, and the multiple engagement segments are spaced apart and surround to form a circular outline that matches the engagement hole.

[0017] In the above technical solution, the number of adjustable feet is further specified as three.

[0018] Two of the adjustable feet are symmetrically installed at both ends of the front part of the cleaning device, and the other adjustable foot is installed in the middle of the rear part of the cleaning device, so that the three adjustable feet are arranged at the three vertices of a preset isosceles triangle.

[0019] In the above technical solution, the bottom of the cleaning equipment is provided with a base, and the base is provided with multiple mounting parts, with the adjusting feet being installed one by one on the mounting parts.

[0020] In the above technical solution, the adjusting foot is further described as an electric push rod.

[0034] Example 1

[0035] See Figures 1 to 4 As shown, the leveling device provided in this application can be used in dishwashers and similar cleaning equipment. The cleaning equipment includes an inner tank where dishes awaiting cleaning can be placed for washing. A filter screen and a water outlet 102 are provided at the bottom of the inner tank. Washing water can flow out from the water outlet 102, and the washed residue can be filtered through the filter screen. The water outlet 102 of the inner tank is equipped with a manifold 105 and a washing heating pump 101. The washing water flowing out of the water outlet 102 flows into the manifold 105 and is guided to the washing heating pump 101, achieving water recycling.

[0036] The washing water heater 101 is installed in the manifold 105 and is used to heat the washing water, which is then delivered to each spray arm via an internal turbine. Therefore, the operating efficiency of the washing water heater 101 directly affects the outlet pressure of the washing water, thus affecting the effectiveness of the washing water in rinsing the tableware. If the water intake of the washing water heater 101 is insufficient, i.e., the water intake per unit time is low, the blades of the washing water heater 101 will continuously spin dry. This can result in low outlet pressure of the washing water, affecting cleaning, or even overheating and damage to the washing water heater 101 due to continuous dry spinning.

[0037] To ensure that the dishwasher and the washing heat pump 101 are installed horizontally after installation, and to avoid insufficient water intake per unit time due to the dishwasher being tilted, this application provides a leveling device on the dishwasher to automatically adjust the horizontal state of the washing heat pump 101.

[0038] Specifically, the leveling device includes a tilt sensor 103 and multiple adjusting feet 104. Since the washing heating pump 101 is installed on the manifold 105, the tilt sensor 103 is also installed on the manifold 105, so that the tilt sensor 103 is closer to the bottom of the inner tank and the position of the washing heating pump 101, thereby enabling more accurate measurement of the tilt angle of the washing heating pump 101 relative to the horizontal plane.

[0039] Multiple adjustable feet 104 are installed at the bottom of the washing equipment and are arranged at intervals. Based on the information fed back by the tilt sensor 103, the tilt sensor 103 is communicatively connected to the multiple adjustable feet 104, so that at least one of the adjustable feet 104 can extend or retract, thereby adjusting the level of the bottom of the inner tank and the washing heating pump 101. During the washing process, the washing water collected at the bottom of the inner tank and entering the washing heating pump 101 can be kept level, which is beneficial to the normal operation of the washing heating pump 101.

[0040] In an optional embodiment, the manifold 105 includes a manifold portion 106 and a mounting portion. Preferably, the manifold portion 106 and the mounting portion are integrally formed to ensure reliable connection and better overall integrity. The manifold portion 106 is installed at the water outlet 102 of the inner tank and has a manifold groove to collect the washing water flowing out of the water outlet 102. The manifold groove has a connecting hole that connects to the washing heating pump 101 so that the washing water collected in the manifold groove can enter the washing heating pump 101 for heating. The manifold groove also has a drain outlet to drain the washing water after cleaning.

[0041] like Figure 2 and Figure 3As shown, the mounting part is plate-shaped and is located on the side of the confluence part 106. The mounting part includes a first mounting part 107 and a second mounting part 108, which are arranged adjacent to each other. The tilt sensor 103 is mounted on the first mounting part 107, and the washing heating pump 101 is mounted on the second mounting part 108, so that the tilt sensor 103 and the washing heating pump 101 are installed in parallel or on the same plane. Thus, the horizontality of the tilt sensor 103 represents the horizontality of the bottom of the inner tank and the washing heating pump 101.

[0042] Furthermore, the washing heating pump 101 is installed on the bottom side of the second mounting part 108, without occupying the space of the upper inner tank, and the top surface of the second mounting part 108 is provided with reinforcing ribs to increase strength. The tilt sensor 103 is also installed on the bottom side of the first mounting part 107, that is, the tilt sensor 103 and the washing heating pump 101 are located on the same side of the mounting part, which can better and more accurately reflect the levelness of the bottom of the inner tank and the washing heating pump 101. Specifically, the bottom of the first mounting part 107 is provided with a mounting groove 109, which is adapted to the tilt sensor 103 so that the tilt sensor 103 is fixed in the mounting groove 109. Figure 3 The tilt sensor 103 shown is a disc-shaped electronic level. A circular mounting groove 109 is provided at the bottom of the first mounting part 107 so that the electronic level can be fitted and installed in the mounting groove 109, making the installation more reliable.

[0043] In an optional embodiment, the bottom of the mounting groove 109 is provided with three positioning protrusions 110, and the three positioning protrusions 110 are evenly arranged to form the plane of the positioning tilt sensor 103.

[0044] In this embodiment, during the manufacturing of the manifold 105, due to production errors, the bottom of the mounting groove 109 inevitably becomes uneven. If the tilt sensor 103 is installed in the uneven mounting groove 109, it is not conducive to controlling the consistency of the horizontality of the tilt sensor 103 installation with the horizontality of the washing heating pump 101. Therefore, based on the theorem that three non-collinear points determine a plane, this application provides three positioning protrusions 110 at the bottom of the mounting groove 109. When the three positioning protrusions 110 jointly support the tilt sensor 103, a plane for positioning the tilt sensor 103 is formed.

[0045] Specifically, for Figure 3 The medium-sized disc-shaped electronic level has three positioning protrusions 110 evenly distributed on a preset circumference, with the center of the preset circumference located on the axis of the electronic level. This ensures that the three positioning protrusions 110 can evenly support the electronic level and prevent local tilting of the electronic level.

[0046] In this embodiment, the snap-fit ​​fixing method for the tilt sensor 103 may include at least one of the following two methods:

[0047] Firstly, the bottom of the mounting groove 109 is provided with a snap-fit ​​hole 111, and the bottom of the tilt sensor 103 is provided with a corresponding first snap-fit ​​112. When the tilt sensor 103 is placed in the mounting groove 109, the first snap-fit ​​112 can be snapped into the snap-fit ​​hole 111 to fix the bottom of the tilt sensor 103.

[0048] Secondly, the groove wall of the mounting groove 109 is provided with a locking block 113. Figure 3 The diagram shows three locking blocks 113. The tilt sensor 103 has three corresponding second latches 114 on its side. Each second latch 114 has a slot, and one side of the slot is an arc transition surface. When the tilt sensor 103 is rotated and installed in the mounting slot 109, the locking block 113 can slide along the transition surface into the slot and lock into the slot of the second latch 114 to fix the side of the tilt sensor 103.

[0049] Specifically, when the bottom and side of the tilt sensor 103 are engaged with the mounting groove 109, when installing the tilt sensor 103 into the mounting groove 109, the tilt sensor 103 needs to be placed in the mounting groove 109 along the depth direction of the mounting groove 109 first, and then the tilt sensor 103 is rotated so that the locking block 113 on the mounting groove 109 engages with the locking groove of the second buckle 114. In this application, the locking hole 111 is a circular hole, and the first buckle 112 includes multiple arc-shaped locking segments, which are spaced apart and surround to form a circular outline that fits the locking hole 111. When installing the tilt sensor 103, the first buckle 112 is first engaged into the locking hole 111. During the process of the first buckle 112 engaging into the locking hole 111, the multiple locking segments first retract and converge to engage into the locking hole 111. When the tilt sensor 103 is rotated in the subsequent rotation, the multiple locking segments can rotate within the locking holes 111 without affecting the action of the locking block 113 locking into the slot of the second latch 114.

[0050] Alternatively, the tilt sensor 103 can also be connected to the first mounting part 107 by screws.

[0053] See Figure 1 and Figure 4As shown, in the optional scheme of this embodiment, the number of adjusting feet 104 is three; two adjusting feet 104 are symmetrically installed at both ends of the front part of the cleaning device, and the other adjusting foot 104 is installed in the middle of the rear part of the cleaning device, so that the three adjusting feet 104 are arranged at the three vertices of a preset isosceles triangle.

[0054] In this embodiment, based on the theorem that three non-collinear points determine a plane, three adjustable feet 104 are used to adjust the level of the device, achieving the adjustment function while also saving costs. The two adjustable feet 104 located at the front and one at the rear allow for leveling the entire device in both the front-back and left-right directions. Furthermore, the three adjustable feet 104 are arranged at the three vertices of a pre-defined isosceles triangle, meaning that any tilting of the device in any direction can be adjusted by adjusting the corresponding adjustable foot 104, simplifying control.

[0055] In an optional embodiment, the bottom of the cleaning equipment is provided with a base 115, and the base 115 is provided with multiple mounting parts 116, with adjustable feet 104 corresponding to each mounting part 116. Optionally, the adjustable feet 104 are electric push rods, and the adjustment range of the electric push rods is 0-70mm.

[0056] In this embodiment, such as Figure 4 As shown, the mounting component 116 includes a horizontally arranged mounting plate 117 and a vertically arranged reinforcing plate 118. An electric actuator is mounted on the top surface of the mounting plate 117, and the mounting plate 117 has mounting holes for connection with the electric actuator. The mounting plate 117 has a through hole 119, through which the drive rod of the electric actuator can pass and abut against the mounting surface of the equipment. By controlling the extension and retraction of the drive rod of the electric actuator, the levelness of the equipment can be adjusted. Two reinforcing plates 118 are also provided at intervals on the top surface of the mounting plate 117 to enhance the overall strength of the mounting component 116.
