Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes processing, and in particular to a clothes processing device. BACKGROUND

[0002] At present, clothes processing devices have become a kind of popular household appliances and are widely used by people. In order to optimize the experience of people in the process of using clothes processing devices, manufacturers usually install a water level detection device in the clothes processing device to accurately control the water level in the clothes processing device, so as to ensure that the water level neither affects the washing effect nor causes overflow accidents due to being too high, nor affects the cleaning effect due to being too low. However, due to the deficiency in the structural design of the water level detection device, the water level detection effect of the clothes processing device is often difficult to achieve the expected effect. CONTENT OF THE UTILITY MODEL

[0003] The present application discloses a clothes processing device which can effectively improve the detection efficiency and stability of a water level detection module on the water level in a washing cavity.

[0004] In order to achieve the above-mentioned purpose, some embodiments of the present application provide a clothes processing device, comprising:

[0005] a box body having an internal space;

[0006] a cylinder body provided in the internal space, the cylinder body having a washing cavity for accommodating objects to be washed;

[0007] a water level detection module provided in the internal space, the water level detection module comprising:

[0008] a detection unit configured to detect the water level of the washing cavity;

[0009] a connecting pipe comprising:

[0010] a first end connected to the washing cavity, the first end having a first pipe opening;

[0011] a second end connected to the detection unit, the second end having a second pipe opening;

[0012] wherein the diameter of the first pipe opening is smaller than the diameter of the second pipe opening.

[0013] Since the first port communicating with the washing cavity has a relatively small caliber, and the first port is arranged close to the bottom of the washing cavity, the first port can be gradually closed by liquid as the water level in the washing cavity rises. Since the first port of the connecting pipe has a small caliber, the liquid in the washing cavity can more easily close the first port, so that the internal part of the detection unit forms a closed air chamber more quickly, thereby effectively improving the detection efficiency and detection stability of the water level detection module on the water level in the washing cavity.

[0014] In some embodiments of the present application, the diameter of the connecting pipe gradually decreases from the second end to the first end.

[0015] Since the first end communicating with the washing cavity has a small caliber and the second end communicating with the detection unit has a large caliber, the liquid in the washing cavity can more easily close the first end of the connecting pipe, so that the internal part of the detection unit can form a closed air chamber more quickly. In addition, since the diameter of the connecting pipe gradually decreases from the second end to the first end, such a gradually changing diameter design is easier to achieve in process production, and can reduce the flow resistance of the liquid and improve the flow stability of the liquid, thereby effectively improving the detection efficiency and detection stability of the water level detection module on the water level in the washing cavity.

[0016] In some embodiments of the present application, the cylinder includes:

[0017] The front end face has a laundry putting opening configured to allow a user to put the laundry to be washed into the washing cavity.

[0018] The rear end face is arranged opposite to the front end face.

[0019] The detection unit is arranged close to the front end face, and in the height direction of the cabinet, the detection unit is located above the cylinder.

[0020] In this way, the detection unit is arranged close to the front end face, which is beneficial for the maintenance personnel to work when installing, maintaining or replacing the detection unit. In addition, in order to effectively and stably detect the water level of the washing cavity by the detection unit, the detection unit is placed above the cylinder, that is, in the height direction of the cabinet, the installation height of the detection unit is higher than that of the washing cavity. On the one hand, this can avoid the detection unit occupying the internal space of the cabinet to affect the washing capacity of the cylinder. On the other hand, based on the principle of communicating vessels, the water level in the washing cavity and the water level of the detection unit will remain the same. Placing the detection unit above the cylinder can effectively prevent the liquid in the washing cavity from contacting the sensor body of the detection unit, thereby facilitating the service life of the detection unit.

[0021] In some embodiments of the present application, the detection unit includes:

[0022] A sensor body connected with the connecting pipe;

[0023] A mounting member provided on one side of the sensor body, the mounting member being provided with a buckle portion;

[0024] The box is provided with a clamping hole configured to pass the buckle portion, so that the detection unit is connected with the box.

[0025] The sensor body is installed on the box by the buckle mode, and the sensor body can be easily disassembled and installed, thereby facilitating the maintenance personnel to install, maintain or replace the detection unit.

[0026] In some embodiments of the present application, the detection unit comprises:

[0027] A sensor body;

[0028] A conduit, one end of the conduit being connected with the sensor body, and the other end of the conduit being in communication with the connecting pipe;

[0029] An air chamber configured to be provided at the connection between the connecting pipe and the conduit to increase the gas containing capacity of the detection unit.

[0030] Specifically, the structure of the air chamber can be a cylindrical cavity with both ends in communication, and the diameter of the air chamber is greater than the diameter of the conduit. Compared with the conduit with a constant diameter, the air chamber with a larger diameter can effectively increase the gas containing capacity of the detection unit, so that the detection unit can detect larger gas pressure changes, thereby effectively improving the accuracy of the detection unit for water level detection.

[0031] In some embodiments of the present application, the air chamber is provided with a first buckling portion, and the cylinder is provided with a second buckling portion, the first buckling portion being configured to be buckled and connected with the second buckling portion, so that the air chamber is installed on the cylinder.

[0032] In this way, the air chamber can be quickly positioned and installed, and the air chamber is installed on the cylinder by buckling connection, which is convenient for maintenance personnel to disassemble and replace the air chamber in the later period, so that the gas containing capacity of the air chamber can be adjusted according to the demand of the clothes treatment device for water level detection, thereby improving the water level detection efficiency and accuracy of the clothes treatment device.

[0033] In some embodiments of the present application, the first buckling portion comprises:

[0034] A buckle ring provided on the outer wall surface of the air chamber, the inner wall surface of the buckle ring being provided with a first clamping portion;

[0035] A second clamping portion is arranged on the outer wall surface of the air chamber, and is located in the buckle ring and arranged opposite to the first clamping portion.

[0036] The second clamping portion comprises:

[0037] A plug-in portion is arranged on the outer wall surface of the cylinder body, and is configured to be plugged between the buckle ring and the second clamping portion.

[0038] A clamping groove is arranged on the plug-in portion, and is configured to be clamped with the first clamping portion when the plug-in portion is plugged into the buckle ring.

[0039] In this way, the clamping groove on the plug-in portion is configured to be clamped with the first clamping portion, which facilitates quick positioning and installation of the air chamber, and facilitates the maintenance personnel to disassemble and replace the air chamber at a later stage. At the same time, the second clamping portion and the buckle ring are configured to guide the plug-in portion to be inserted between the buckle ring and the second clamping portion, and limit the movement space of the plug-in portion, so as to avoid the plug-in portion from being pulled out of the buckle ring and the second clamping portion, and to achieve stable connection between the air chamber and the cylinder body.

[0040] In some embodiments of the present application, a plurality of limiting portions are arranged on the side of the cylinder body close to the detection unit, and the plurality of limiting portions are arranged at intervals along the circumference of the cylinder body. The plurality of limiting portions are configured to be connected with the conduit, so as to install the conduit on the cylinder body.

[0041] Since the internal space of the cabinet is limited, and the cylinder body is provided with a space for accommodating the laundry to be washed as much as possible, the limiting portion is arranged to install the conduit on the cylinder body, so as to limit the installation position of the conduit, thereby improving the utilization rate of the internal space of the cabinet, and enabling the laundry treatment device to be designed to be light and thin and have large capacity.

[0042] In some embodiments of the present application, a drain pipe is connected to the bottom of the cylinder body, the drain pipe is communicated with the washing cavity, and the drain pipe is communicated with the connecting pipe.

[0043] The drain pipe and the connecting pipe are integrally formed; and / or,

[0044] A reinforcing rib is arranged at the connection between the drain pipe and the connecting pipe.

[0045] Since the drain pipe is arranged at the bottom of the cylinder body, the drain pipe and the connecting pipe bear a large water pressure. In this way, the mechanical strength between the drain pipe and the connecting pipe can be improved, and the problem of breakage at the connection between the drain pipe and the connecting pipe can be avoided, thereby improving the use reliability of the laundry treatment device.

[0046] In some embodiments of the present application, the cylinder body comprises:

[0047] an outer tub provided in the inner space, the outer tub having a water storage cavity for storing washing water, the outer tub being provided with an air return opening on a rear end surface thereof;

[0048] an inner tub rotatably provided in the water storage cavity, the inner tub having the washing cavity in communication with the water storage cavity;

[0049] The laundry treatment device further comprises:

[0050] a drying air duct located outside the outer tub, one end of the drying air duct being in communication with the air return opening, and the other end being in communication with the inner tub;

[0051] a condensation disc provided on the rear end surface, the condensation disc covering the air return opening.

[0052] In this way, the drying air duct is used to communicate the outer tub, so that air circulation can be formed among the inner tub, the outer tub and the drying air duct. Specifically, air in the washing cavity of the inner tub can enter the inner part of the outer tub, enter the drying air duct through the air return opening on the rear end surface of the outer tub, and then return to the washing cavity, thereby forming air circulation flow and realizing the drying function of the laundry treatment device.

[0053] Compared with the prior art, the application has the following beneficial effects:

[0054] The laundry treatment device disclosed in the application comprises a box body, a tub and a water level detection module. The box body has an inner space, the tub and the water level detection module are arranged in the inner space, the tub has a washing cavity for accommodating washing objects, and the water level detection module comprises a detection unit and a connecting pipe. The detection unit is configured to detect the water level in the washing cavity, and the connecting pipe has a first pipe opening and a second pipe opening. The diameter of the first pipe opening is smaller than that of the second pipe opening. Since the diameter of the first pipe opening in communication with the washing cavity is relatively small, the liquid in the washing cavity can more easily seal the first pipe opening, so that a closed air chamber is formed in the detection unit more quickly. Therefore, the detection efficiency and stability of the water level detection module for the water level in the washing cavity can be effectively improved. BRIEF DESCRIPTION OF DRAWINGS

[0082] Clothes processing devices have been deeply involved in people's daily life and have been widely used as an indispensable household appliance. In order to further improve the satisfaction and convenience of users when using clothes processing devices, manufacturers have devoted themselves to the innovation and optimization of technology.

[0083] Currently, the inventors monitor and control the water level in the device by installing a water level detection device inside the clothes processing device to prevent the risks of poor washing effect, increased energy consumption, and even overflow accidents caused by high water level, while also avoiding the problems of insufficient cleaning strength and decreased laundry cleanliness caused by low water level.

[0084] However, the inventors found that due to some defects and deficiencies in the structural design of the water level detection device, the water level detection effect of the clothes processing device in actual application often fails to fully meet people's expectations.

[0085] Therefore, the clothes processing device provided by the present application can effectively improve the detection efficiency and stability of the water level detection module in the washing cavity.

[0086] The technical solutions of the present application will be further described below in conjunction with the embodiments and drawings.

[0087] Please refer to Figures 1 to 4 , wherein Figure 1 is a structural schematic diagram of the clothes processing device provided by the embodiments of the present application, Figure 2 is an exploded view of the clothes processing device provided by the embodiments of the present application, Figure 3 is a side view of the clothes processing device provided by the embodiments of the present application, Figure 4 is Figure 3 is a sectional view of A-A. Some embodiments of the present application provide a clothes processing device 100. Optionally, the clothes processing device 100 can include but is not limited to a washing machine, a clothes dryer, or a washer-dryer, etc. The washing machine can include but is not limited to a drum washing machine or a pulsator washing machine, etc., which is not limited by the embodiments of the present application.

[0088] In some embodiments, the clothes processing device 100 includes a cabinet 1, and the cabinet 1 has an internal space 11.

[0089] It can be understood that the bottom of the cabinet 1 to the top of the cabinet 1 is the height direction F3 of the cabinet 1, and the cabinet 1 also has a width direction F1 and a depth direction F2. Among them, one side end of the cabinet 1 to the other side end of the cabinet 1 is the width direction F1 of the cabinet 1, and the front side of the cabinet 1 is the side of the cabinet 1 facing the user, and any two of the width direction F1, the depth direction F2 and the height direction F3 of the cabinet 1 are perpendicular to each other. That is, the width direction F1 of the cabinet 1 is perpendicular to the depth direction F2 of the cabinet 1, the width direction F1 of the cabinet 1 is perpendicular to the height direction F3 of the cabinet 1, and the depth direction F2 of the cabinet 1 is perpendicular to the height direction F3 of the cabinet 1. Among them, the cabinet 1 is surrounded by a cylinder extending upward and downward, and the whole is rectangular, of course, it can also be other shapes, such as a cylindrical shape, which is not limited here. The bottom of the cabinet 1 is provided with a base, and the base supports the cabinet 1. The base is provided with a downwardly protruding ground contact such as a foot to provide a gap between the base and the ground.

[0090] The laundry treatment apparatus 100 also includes a tub 2 provided in the internal space 11, and the tub 2 has a washing cavity 221 for accommodating laundry.

[0091] Please refer to Figures 1 to 4 The laundry is placed in the washing cavity 221 of the tub 2, and the washing cavity 221 is used to wash the laundry.

[0092] Please refer to Figure 2 In some embodiments, the tub 2 includes an outer tub 21 provided in the internal space 11, and the outer tub 21 has a water storage cavity 211 for storing washing water. The outer tub 21 is configured as a barrel for containing washing water, i.e., the water storage cavity 211 of the outer tub 21 is used to store washing water.

[0093] In some embodiments, the tub 2 also includes an inner tub 22 rotatably provided in the water storage cavity 211, and the inner tub 22 has a washing cavity 221 in communication with the water storage cavity 211. Holes are formed in the outer wall of the inner tub 22, and water in the outer tub 21 can enter the inner tub 22 through the holes to clean the laundry in the inner tub 22.

[0094] Optionally, the inner tub 22 can be rotatably provided in the water storage cavity 211 by, for example, a drive motor, so as to rotate at high speed under the drive of the drive motor to beat the laundry and clean the laundry or spin dry.

[0095] In some embodiments, as known from the foregoing, the laundry treatment apparatus 100 can be a washer-dryer, and based on this, the rear end surface 212 of the outer tub 21 is provided with an air return opening 2121.

[0096] In some embodiments, the clothes treatment apparatus 100 further comprises a drying air duct (not shown) located outside the outer drum, one end of the drying air duct being in communication with the air return port 2121, and the other end being in communication with the inner drum 22. The drying air duct is used to communicate with the washing cavity 221, so that air circulation can be formed between the inner drum 22, the outer drum 21 and the drying air duct. Specifically, the air in the washing cavity 221 of the inner drum 22 can enter the inside of the outer drum 21, enter the drying air duct through the air return port 2121 on the rear end surface 212 of the outer drum 21, and then return to the washing cavity 221, thereby forming an air circulation flow and realizing the drying function of the clothes treatment apparatus 100.

[0097] In some embodiments, the clothes treatment apparatus 100 further comprises a condensing disc (not shown) arranged on the rear end surface 212, the condensing disc covering the air return port 2121. The condensing disc is used as a condenser and can condense the hot and humid air flowing through the drying air duct to cool and dehumidify the hot and humid air flowing through.

[0098] It can be understood that the shape of the condensing disc can be consistent with the shape and curvature of the air return port 2121, so as not to occupy too much internal space 11.

[0099] Therefore, the clothes treatment apparatus 100 provided by the embodiments of the present application can realize the functions of a washing and drying all-in-one machine that can both wash and dry clothes, without the need for manual multiple times to take clothes, effectively improving the user's experience.

[0100] Referring to Figure 3 In some embodiments, the clothes treatment apparatus 100 further comprises a water level detection module 3 arranged in the internal space 11, the water level detection module 3 being used to detect the water level in the washing cavity 221.

[0101] In some embodiments, the water level detection module 3 comprises a detection unit 31 configured to detect the water level of the washing cavity 221. It can be understood that the detection unit 31 can include but is not limited to a pressure type, ultrasonic type, optical type, float type water level sensing unit, etc., and the embodiments of the present application do not limit this. The pressure sensing module is used to communicate with the washing cavity 221 to detect the change of the pressure in the detection unit 31 during the water inlet process of the clothes treatment apparatus 100, so as to realize the water level detection of the washing cavity 221.

[0102] Referring to Figure 5A wherein, Figure 5A to Figure 4The local enlarged view at B. The water level detection module 3 further comprises a connecting pipe 32, the connecting pipe 32 is used to connect the detection unit 31 and the washing cavity 221, so that the detection unit 31 can realize the detection of the water level in the washing cavity 221. Specifically, as known from the foregoing, the outer drum 21 has the water containing cavity 211, and the connecting pipe 32 can be connected to the water containing cavity 211. Since the water containing cavity 211 is in communication with the washing cavity 221, and the washing cavity 221 is located in the water containing cavity 211, connecting the connecting pipe 32 to the water containing cavity 211 can also realize the detection of the water level in the washing cavity 221. And since the inner drum 22 is rotatably arranged in the water containing cavity 211, and the outer drum 21 is fixed, connecting the connecting pipe 32 to the water containing cavity 211 can make the water level detection effect of the water level detection module 3 better and more stable, thereby realizing efficient and intelligent washing of the clothes treatment device 100.

[0103] In some embodiments, the connecting pipe 32 comprises a first end 321 connected to the water containing cavity 211, and the first end 321 has a first pipe opening 3211; the connecting pipe 32 comprises a second end 322 connected to the detection unit 31, and the second end 322 has a second pipe opening 3221. By connecting the first end of the connecting pipe to the water containing cavity 211 and connecting the second end to the detection unit 31, the water level detection of the clothes treatment device 100 can be realized between the water containing cavity 211 and the detection unit 31.

[0104] Optionally, the diameter of the first pipe opening 3211 is smaller than the diameter of the second pipe opening 3221. It can be understood that, since the first pipe opening 3211 in communication with the washing cavity 221 has a relatively small diameter, and the first pipe opening 3211 is arranged close to the bottom of the washing cavity 221, the first pipe opening 3211 can be gradually closed by the liquid as the water level in the washing cavity 221 rises. Since the first pipe opening 3211 of the connecting pipe 32 has a small diameter, the liquid in the washing cavity 221 can more easily close the first pipe opening 3211, thereby forming a closed air chamber 314 inside the detection unit 31 more quickly. Thus, the detection efficiency and stability of the water level detection module 3 for the water level in the washing cavity 221 can be effectively improved.

[0105] The cross-sectional shape of the connecting pipe 32 can include, but is not limited to, a circle, a polygon (such as a rectangle), an ellipse, etc., which is not limited in the present application.

[0106] It can be understood that the diameter refers to the farthest distance between one end of the connecting pipe 32 to the other end opposite to it in the cross section. For example, when the cross-sectional shape of the connecting pipe 32 is circular, the diameter is the diameter of the circular cross section.

[0107] Of course, as another embodiment, when the overall shape of the connecting pipe 32 is irregular, that is, the cross-sectional shape is not the same at different places, the diameter still refers to the farthest distance between one end of the cross-section and the opposite end at the pipe opening of the connecting pipe 32.

[0108] Optionally, the diameter K1 of the first port 3211 is smaller than the diameter K2 of the second port 3221, which may include:

[0109] In one example, such as Figure 5B As shown, the connecting pipe 32 is tapered at the first port 3211 of the first end 321, and the diameter of the connecting pipe 32 is roughly uniform at other positions except for the first port 3211, so that the diameter K1 of the first port 3211 is smaller than the diameter K2 of the second port 3221 of the second end 322.

[0110] In another example, such as Figure 5C As shown, the connecting pipe 32 is flared at the second port 3221 of the second end 322, and the diameter of the connecting pipe 32 is roughly uniform at other positions except for the second port 3221, so that the diameter K1 of the first port 3211 is smaller than the diameter K2 of the second port 3221 of the second end 322.

[0111] In another example, such as Figure 5D As shown, the connecting pipe 32 is narrowed at the first port 3211 at the first end 321 and widened at the second port 3221 at the second end 322. The diameter of the connecting pipe 32 is roughly uniform at other positions except for the first port 3211 and the second port 3221. Thus, the diameter K1 of the connecting pipe 32 at the first port 3211 is the smallest, while the diameter K2 at the second port 3221 is the largest.

[0112] In another example, such as Figure 5E As shown, the diameter of the connecting pipe 32 gradually decreases from the second end 322 towards the first end 321. That is, the diameter of the connecting pipe 32 is largest at the second opening 3221 of the second end 322 and smallest at the first opening 3211 of the first end 321. Moreover, the gradual change in the diameter of the connecting pipe 32 makes this gradual diameter design easier to implement in the manufacturing process. It also avoids rapid changes in water pressure within the water level detection module 3 due to abrupt changes in the diameter of the connecting pipe 32, thereby reducing the flow resistance of the liquid and improving the flow stability of the liquid, thus improving the stability of the water level detection module 3 in detecting the water level in the washing chamber 221.

[0113] It can be seen that, regardless of which example is used, as long as it can be achieved that the diameter K1 of the first port 3211 of the connecting pipe 32 is smaller than the diameter K2 of the second port 3221, this embodiment does not make specific limitations on this.

[0114] The present application sets the caliber of the first pipe opening 3211 to be smaller than the caliber of the second pipe opening 3221, that is, because the caliber of the first end 321 communicating with the washing cavity 221 is smaller and the caliber of the second end 322 communicating with the detection unit 31 is larger, the liquid in the washing cavity 221 can more easily seal the first end 321 of the connecting pipe 32, and the inside of the detection unit 31 can more quickly form a sealed air chamber 314, thereby effectively improving the detection efficiency and stability of the water level detection module 3 on the water level in the washing cavity 221.
