[0022] By forming an assembly groove on the outer wall surface of the base, the base can be easily clamped on the mounting hole of the housing of the household appliance through the assembly groove.

[0023] In some embodiments of the present application, the mounting portion includes:

[0024] A fixing plate is arranged on the outer wall surface of the base in an annular manner, and a fixing hole is arranged on the fixing plate.

[0025] By arranging a fixing plate on the outer wall surface of the base, the fixing plate is provided with fixing holes, so that the base can be fixedly installed on the housing of the household appliance.

[0026] In a second aspect, the utility model further provides a household appliance, comprising:

[0027] a housing having a mounting hole formed therein; and,

[0028] As in any one of the embodiments of the first aspect above, the wire protection sleeve structure is arranged on the mounting hole.

[0029] In some embodiments of the present application, the household appliance further includes:

[0030] Wiring trough structure;

[0031] Electric control box;

[0032] The wiring trough structure and the electric control box are both located in the outer shell, at least part of the internal wiring harness of the electric control box is located in the wiring trough structure, and the external wiring harness enters the outer shell through the wire sheath structure and is electrically connected to the electric control box.

[0033] Compared with the prior art, the advantages and positive effects of the utility model are: by setting a base and a sleeve, the base presents a three-dimensional structure, a through hole is formed on the end face of the base, the sleeve is arranged on the end face of the base and extends in a direction away from the base, the sleeve is connected to the through hole, the sleeve is configured for allowing the power harness to pass through, and the sleeve wraps the power harness inside, which can not only achieve the effect of sealing and waterproofing, but also protect the power harness from being pinched and damaged; the wire protection sleeve structure of the present application is relatively simple, convenient for production and installation, and conducive to cost saving.

In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0055] In one aspect, combining Figure 1 As shown, an embodiment of the present disclosure further provides a household appliance, which includes a housing 2 and a wire protection cover structure 1.

[0056] A mounting hole is formed on the housing 2; the wire protection sleeve structure 1 is arranged on the mounting hole.

[0057] Household appliances include but are not limited to electric water heaters, gas water heaters, washing machines, etc. Other devices that require power cord waterproofing are also applicable. The following takes an electric water heater as an example.

[0058] An electric water heater uses electricity as its main energy source. The high-temperature heat generated after power is turned on directly heats the water stored in the electric water heater to prepare hot water.

[0059] An electric water heater usually includes a water tank, an electric heating component, an electric control board and other components. A water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank. The electric control board is used to control the on and off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0060] For the water tank of the electric water heater, the water tank generally includes an outer shell 2 and an inner tank, and an insulation layer is formed between the outer shell 2 and the inner tank. The outer shell 2 is generally made of plastic material to meet the design requirements of beautiful and diverse shapes; the inner tank can be made of metal or plastic as needed.

[0061] In addition, the insulation layer formed between the outer shell 2 and the inner shell is made of commonly used insulation materials such as asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good insulation effect, the insulation layer is usually formed by foaming.

[0062] Among them, for the inner tank using a metal tank body, the interior of the inner tank is prone to corrosion due to the influence of water quality. For this reason, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0063] Since magnesium is the metal with the lowest potential in the electrochemical series and is physiologically non-toxic, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod is directly related to the length of time the inner liner is protected and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.

[0064] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to transport cold water to the water storage cavity formed in the water tank, while the hot water in the water storage cavity is output from the water outlet pipe.

[0065] For the electric heating component, electric heating methods such as electric heating wire, magnetic energy or silicon tube heating can be used to heat the water stored in the water storage cavity.

[0066] As for the electric control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the power on and off operation of the electric heating components.

[0067] When the electric water heater is working, the electric control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electric control board controls the electric heating component to be powered off.

[0068] In another aspect, combined Figures 2 to 5 As shown, an embodiment of the present disclosure provides a wire protection sleeve structure 1 , which includes a base 11 and a sleeve 12 .

[0069] The base 11 is a three-dimensional structure, specifically, the base 11 is cylindrical, cubic or polygonal, etc. Of course, the shape of the base 11 includes but is not limited to the above forms. A through hole 111 is formed on the end surface of the base 11.

[0070] Specifically, the base 11 may be a solid structure or a hollow structure, and the specific situation may be set according to actual needs.

[0071] Combination Figure 2 and Figure 3 As shown, the sleeve 12 is disposed on the end surface of the base 11 and extends in a direction away from the base 11. The sleeve 12 is connected to the through hole 111. The sleeve 12 is configured to allow the power harness to pass through and abut against the outer wall of the power harness.

[0072] Specifically, the sleeve 12 and the base 11 may be an integrally formed structure, or may be fixedly connected by bonding.

[0073] Specifically, the inner diameter of the portion where the sleeve 12 and the base 11 are connected is equal to the diameter of the through hole 111 , or the inner diameter of the portion where the sleeve 12 and the base 11 are connected is slightly larger than the diameter of the through hole 111 .

[0074] In some embodiments of the present application, the sleeve 12 has elasticity in the radial direction.

[0075] Specifically, by setting a through hole 111 on the end face of the base 11 and setting a sleeve 12 at a position corresponding to the through hole 111, when the power harness is installed, the power harness can pass through the through hole 111 and the sleeve 12. Since the inner wall surface of the sleeve 12 is in contact with the outer wall surface of the power harness and the sleeve 12 is elastic in the radial direction, the sealing effect between the sleeve 12 and the power harness can be improved, thereby achieving a waterproof effect.

[0076] Specifically, the sleeve 12 is used for the power harness to pass through, and is in contact with the outer wall of the power harness, so that the sleeve 12 is tightly attached to the outer side of the power harness, wrapping the power harness, which can not only achieve the effect of sealing and waterproofing, but also protect the power harness from being pinched and damaged; the wire protection sleeve structure 1 of the present application is relatively simple, convenient for production and installation, and conducive to cost saving.

[0077] In certain embodiments of the present application, Figure 4 and Figure 5 As shown, the sleeve 12 is contracted in a direction away from the base 11 .

[0078] Specifically, by tightening the sleeve 12 in the direction away from the base 11, the inner diameter of the sleeve 12 gradually decreases in the direction away from the base 11, which makes it easy for people to cut the sleeve 12 according to the thickness of the power harness, so that the aperture of the free end of the sleeve 12 can match power harnesses of different thicknesses, thereby expanding the scope of application.

[0079] At the same time, the sleeve 12 is tightened in the direction away from the base 11, and the bottom end of the inner wall of the sleeve 12 tends to tilt downward. When water splashes on the inner wall of the sleeve 12 or water droplets adhere to it, it is convenient for the water to flow out from the inner wall of the sleeve 12 to prevent water from entering the housing 2.

[0080] Specifically, the inner hole of the sleeve 12 may be circular, square or polygonal, and may be set according to actual needs.

[0081] In some embodiments of the present application, Figure 5 As shown, the inner hole of the sleeve 12 is stepped.

[0082] Specifically, by setting the inner hole of the sleeve 12 to be stepped, that is, holes of different diameters are provided on the same sleeve 12, when power wire harnesses of different thicknesses are introduced, the excess parts are cut off according to the corresponding aperture steps, so that the power wire harnesses of different thicknesses can achieve a sealed and waterproof effect after introduction; in addition, the inner hole of the sleeve 12 is stepped, which is convenient for processing and manufacturing, and is convenient for precise cutting according to the thickness of the power wire harness when used.

[0083] Exemplarily, the inner hole of the sleeve 12 is a three-step hole.

[0084] In some embodiments of the present application, the end of the sleeve 12 facing away from the base 11 is a closed structure.

[0085] Specifically, the closed end of the sleeve 12 can be cut according to actual needs so that the sleeve 12 is in contact with the outer wall of the power wiring harness. By setting the end of the sleeve 12 facing away from the base 11 to a closed structure, when multiple sleeves 12 are provided on the base 11, when the actual number of power wiring harnesses is greater than the number of sleeves 12, the sleeve 12 without the power wiring harness installed is in a closed state, and water cannot enter the interior through the sleeve 12, which is beneficial to maintaining the sealing and waterproof effect of the wire protection sleeve structure 1.

[0086] In some embodiments of the present application, the sleeve 12 is made of an elastic material, and the elastic material includes but is not limited to rubber.

[0087] Specifically, the sleeve 12 is made of an elastic material, which has good elasticity, so that power wire harnesses of different specifications and thicknesses can pass through the sleeve 12 and match with the sleeve 12 .

[0088] Exemplarily, the sleeve 12 is made of one or more of fluororubber, natural rubber, silicone rubber, nitrile rubber or styrene-butadiene rubber.

[0089] In some embodiments of the present application, the sleeves 12 correspond to the through holes 111 one by one.

[0090] In other embodiments of the present application, the sleeve 12 is provided with one or more sleeves.

[0091] Exemplarily, the sleeves 12 are provided with 2, 3, 4, 5 or 6. Of course, the number of power harness barrels includes but is not limited to the above number. The specific number can be set according to actual needs. The plurality of sleeves 12 are evenly distributed on the base 11.

[0092] In actual installation and use, the number of power wire harnesses installed in the power line with the same wire protection sleeve structure 1 may be different, and the thickness of each power wire harness of the same power line may be different. The sleeves 12 on the base 11 can be cut according to the thickness of the corresponding power wire harness, and the corresponding structure can be removed so that the sleeve 12 can be adapted to each power wire harness of different thicknesses, so that multiple power wire harnesses of different numbers and thicknesses are sealed with the adapted sleeves 12 after entering the line, thereby achieving a waterproof effect, and adjacent power wire harnesses do not affect each other.

[0093] In this way, there is no need to add additional accessories and space, the structure is exquisite, beautiful, and well concealed, which is conducive to cost saving.

[0094] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the base 11 is a cylindrical structure with one end open, and the through hole 111 is located on the bottom wall of the base 11 .

[0095] Specifically, by setting the base 11 as a cylindrical structure with one end open, the cylindrical structure can not only save materials and reduce the overall weight; at the same time, the cylindrical structure is easy to deform, which facilitates the installation of the base 11; in addition, the sealing effect between the base 11 and the installation hole to be installed is improved.

[0096] During actual installation and use, the open end of the base 11 faces the outside of the shell 2, and the sleeve 12 is located inside the shell 2. In this way, the appearance is relatively flat and beautiful. At the same time, the sleeve 12 is located inside the shell 2 to avoid the sleeve 12 hindering the installation due to occupying space.

[0097] In some embodiments of the present application, the cable sheath structure 1 further includes a mounting portion 13 .

[0098] The mounting portion 13 is disposed on the outer side wall of the base 11 , and the mounting portion 13 is configured to be used for mounting the cable sheath structure 1 .

[0099] Specifically, by providing a mounting portion 13 on the outer wall of the base 11 , the mounting portion 13 facilitates fixing the wire protection sleeve structure 1 to the housing 2 of the electric water heater.

[0100] In some embodiments of the present application, the mounting portion 13 includes a mounting groove 131 formed on an outer wall surface of the base 11 .

[0101] Specifically, by forming an assembly groove 131 on the outer wall surface of the base 11, the base 11 can be clamped on the installation hole of the housing 2 of the electric water heater through the assembly groove 131, which is convenient for installation.

[0102] In some embodiments of the present application, Figure 5 As shown, the cable gland structure 1 further includes a first flange 132 and a second flange 133 .

[0103] The first flange 132 is disposed on the outer wall surface of the opening end of the base 11;

[0104] The second flange 133 is arranged on the outer wall surface of the bottom end surface of the base 11 . The second flange 133 and the first flange 132 are arranged at intervals. The second flange 133 , the first flange 132 and the outer wall surface of the base 11 together form an assembly groove 131 .

[0105] In some embodiments of the present application, the mounting portion 13 includes a fixing plate.

[0106] The fixing plate is arranged on the outer wall surface of the base 11, and fixing holes are arranged on the fixing plate.

[0107] Specifically, by arranging a fixing plate on the outer wall surface of the base 11, the fixing plate is provided with fixing holes, so that the base 11 can be fixedly installed on the housing 2 of the electric water heater.

[0108] The embodiments of the present disclosure further provide a household appliance, comprising a housing 2 and a wire protection sleeve structure 1 as described in any one of the embodiments of the first aspect above.

[0109] A mounting hole is formed on the housing 2; the wire protection sleeve structure 1 is arranged on the mounting hole.

[0110] Since the household appliance includes the wire protection cover structure 1 of any one of the embodiments of the first aspect, it has all the beneficial effects of the wire protection cover structure 1 of any one of the embodiments of the first aspect, which will not be described in detail here.

[0111] In certain embodiments of the present application, the household appliance further includes a wiring trough structure 3 and an electric control box 4 .

[0112] Among them, the wiring trough structure 3 and the electric control box 4 are both located in the outer shell 2, at least part of the internal wiring harness of the electric control box 4 is located in the wiring trough structure 3, and the external wiring harness enters the outer shell 2 through the wire sheath structure 1 and is electrically connected to the electric control box 4.

[0113] In another aspect, combined Figures 7 to 10 As shown, in certain embodiments of the present application, a wiring slot structure 3 is provided, and the wiring slot structure 3 includes a slot head 31 and a slot body 32 .

[0114] The slot body 32 is connected to the slot head 31. The slot body 32 and the slot head 31 are used to place the wiring harness, and the width of the slot body 32 is smaller than the width of the slot head 31.

[0115] Among them, combined Figure 7 and Figure 8 As shown, the slot head 31 is provided with a plurality of partitions 311 at intervals along the width direction, and the plurality of partitions 311 divide the slot head 31 into a plurality of guide grooves 312. Fig.10 As shown, the plurality of guide grooves 312 are all connected to the groove body 32 , and steps 313 are provided in some of the guide grooves 312 , and the wire harnesses are arranged in the guide grooves 312 in a layered structure.

[0116] Specifically, by providing the slot head 31 and the slot body 32 , the slot body 32 is connected to the slot head 31 , the slot body 32 and the slot head 31 can control the routing direction of the wire harness, so that the wire harness can be routed regularly in the direction of the slot shape.

[0117] Combination Fig. 9As shown, the slot head 31 is provided with a plurality of partitions 311 at intervals along the width direction, and the plurality of partitions 311 divide the slot head 31 into a plurality of guide slots 312, and the plurality of guide slots 312 are all connected with the slot body 32, and steps 313 are provided in some of the guide slots 312, and the wiring harnesses are arranged in a layered structure in the guide slots 312, and the wiring harnesses are routed in layers to avoid crossing and confusion of the wiring harnesses; the width of the slot body 32 is smaller than the width of the slot head 31, which is beneficial to reducing the width and overall size of the wiring slot, reducing the occupied space, and facilitating installation.

[0118] Exemplarily, the number of the partitions 311 is three, and the three partitions 311 divide the slot head 31 into four guide slots 312 .

[0119] In certain embodiments of the present application, the groove body portion 32 is circular, arc-shaped, straight-line, curved or L-shaped. Of course, the shape of the groove body portion 32 includes but is not limited to the above types.

[0120] The connection between the slot head 31 and the slot body 32 has a smooth transition. By setting the width of the slot body 32 to be smaller than the size of the slot head 31 and setting a step 313 in part of the guide slot 312, the wiring harness can be divided into an upper and lower double-layer routing form from the beginning. At the same time, this routing form can be continued to the slot body 32 to avoid crossing and confusion of the wiring harness.

[0121] It should be noted that the step 313 can be arranged on one side of the slot head 31 or in the middle of the slot head 31 , and can be arranged according to actual needs.

[0122] In some embodiments of the present application, Figure 7 and Fig. 9 As shown, the groove body portion 32 is provided with a receiving protrusion 321 along the width direction, and the receiving protrusion 321 is configured to hide the wire harness.

[0123] Specifically, by arranging the accommodating protrusion 321 along the width direction of the groove body 32, the space at the accommodating protrusion 321 is larger, and the accommodating protrusion 321 can hide the wiring harness that exceeds the actual routing length, preventing the wiring harness from protruding or bending, which is beneficial to protecting the wiring harness and making the wiring harness more regularly arranged.

[0124] In other embodiments of the present application, the accommodating protrusion 321 is semi-annular, arc-shaped or polygonal.

[0125] Specifically, by configuring the accommodating protrusion 321 to be semi-circular, arc-shaped, or polygonal, the wire harness can be bent and fitted against the inner wall surface of the accommodating protrusion 321 .
