Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a detachable faucet, heating device and household appliance. Background Technology

[0002] Heating devices are the main components of household heating appliances such as floor scrubbers, garment steamers, washing machines, and dishwashers. When these appliances are working, water from their tanks is injected into the heating device for heating or evaporation, and the resulting hot water or steam flows out from the working surface of the appliance, thus meeting the needs of different household appliances.

[0003] The heating device of the household appliance is equipped with a water channel. The surface of the chamber has an inlet and an outlet. Cold water enters the chamber through the inlet and flows through the water channel to the steam outlet. During this process, the heating element heats the water inside the chamber, generating steam which is discharged from the steam outlet. Water nozzles are installed at both the inlet and outlet. One end of the heating device is connected to the water tank of the household appliance through a water nozzle and a pipe, and the other end is connected to the outlet or steam outlet of the heating appliance through a water nozzle and a pipe, thus enabling the household appliance to work.

[0004] In the prior art, the water nozzle of the heating device is formed by welding. In this welding method, one end of the water nozzle needs to be clamped to the water inlet and outlet of the heating device, and the height of the water nozzle needs to be adjusted to ensure that the water nozzle is connected to the water channel of the heating device and maintains a suitable distance from the bottom of the water channel. Finally, the water nozzle and the water inlet and outlet of the heating device are welded together.

[0005] In the above solution, the water nozzle is cylindrical and extends directly into the inlet / outlet interface of the heating device, where it is welded together to ensure a tight seal between the cylindrical nozzle and the heating device's inlet / outlet interface. While this fixed connection method is simple in structure, it also has some obvious limitations. First, the nozzle's position is fixed, making it impossible to remove and replace it from the heating device, resulting in maintenance difficulties. Furthermore, it cannot be adjusted to meet different product requirements, significantly limiting the product's versatility and adaptability. When it is necessary to update or iterate different product models, heating devices with different nozzle models must be remanufactured, which not only increases production costs but also reduces production efficiency.

[0006] Therefore, this application aims to solve the problem of water taps being detachably installed on different heating devices while ensuring the normal sealing performance of the water taps. Utility Model Content

[0007] The main purpose of this utility model is to provide a detachable faucet, heating device and household appliance, with the aim of designing a faucet that can be detached from the heating device and ensuring the sealing of the connection between the faucet and the heating device.

[0008] To achieve the above objectives, this utility model proposes a detachable water tap, including a water tap body, wherein a flow channel hole is provided in the axial direction of the water tap body, and the water tap body includes:

[0009] Connector;

[0010] A connecting portion is provided at one end of the plug-in portion;

[0011] A limiting member is disposed on the outer wall of the connecting portion; and

[0012] A blocking member is provided at one end of the insertion portion;

[0013] When the plug is connected to the inlet / outlet of the heating device, the limiting member and the blocking member are located outside and inside the inlet / outlet, respectively, and partially fit the edge of the inlet / outlet.

[0014] Furthermore, the blocking member includes a blocking portion disposed at the end of the insertion portion and protruding from the outer wall of the insertion portion.

[0015] Furthermore, at least one stepped barrier is provided at the end of the plug portion.

[0016] Furthermore, the limiting member is integrally formed with the connecting portion and / or the blocking member is integrally formed with the insertion portion.

[0017] Furthermore, the blocking member includes a guide portion disposed at the end of the insertion portion and inclinedly disposed on the outer periphery of the end face of the insertion portion.

[0018] Furthermore, the main body of the faucet is cylindrical, L-shaped, T-shaped, or Y-shaped.

[0019] Furthermore, the limiting member is at least one boss protruding from the outer wall of the insertion portion.

[0020] This application also discloses a heating device equipped with the aforementioned detachable water nozzle. The heating device includes a heating module and a heating element. The heating element is disposed on one side of the heating module. The heating module includes a fluid channel and inlet / outlet ports at both ends of the fluid channel. The plug-in portion is detachably sealed to the inlet / outlet ports. A gap is provided between the blocking member and the heated surface of the fluid channel.

[0021] Furthermore, the inlet and outlet ports of the heating device are detachably fitted with a sealing element, and the limiting member and the blocking member engage and seal on both sides of the sealing element.

[0022] This application also discloses a household appliance equipped with the aforementioned heating device.

[0023] The above technical solution has the following advantages:

[0024] This utility model divides the faucet body into a plug-in part, a blocking component, and a limiting component. The blocking component is located at one end of the plug-in part, and the limiting component is located on the outer wall of the plug-in part. When the plug-in part is installed with the heating device, the blocking component is embedded in the inlet / outlet interface of the heating device, and the limiting component can abut against the surface of the inlet / outlet interface, ensuring that the faucet body is in the same position every time it is installed. The blocking component and the limiting component are engaged together in the inlet / outlet interface, which improves the sealing of the installation. At the same time, it also ensures that the faucet and the heating device can be detached, which is convenient for subsequent maintenance and replacement, and also improves the versatility of the product.

[0025] The barrier part of this utility model is embedded in the inlet and outlet interface, so that the barrier part is separated from the heating surface of the heating device, avoiding the heat of the heating device from being transferred to the plug part, which may cause the seal in contact with the plug part to age and deform. If the water tap body is made of plastic material, it may also cause deformation and glue melting risk of the water tap body. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0035] like Figure 3 and Figure 4 As shown, a detachable faucet includes a faucet body 3 with a flow channel hole in the axial direction. The faucet body 3 includes a plug-in portion 31, a connecting portion 32, a limiting member 33, and a blocking member 34. The connecting portion 32 is disposed at one end of the plug-in portion 31. The limiting member 33 is disposed on the outer wall of the faucet body 3. The blocking member 34 is disposed at one end of the plug-in portion 31. When the plug-in portion 31 is connected to the inlet / outlet interface 11 of the heating device, the limiting member 33 and the blocking member 34 are located outside and inside the inlet / outlet interface 11, respectively, and partially fit against the edge of the inlet / outlet interface 11. The outer edge of the inlet / outlet interface 11 refers to its edge facing the external environment, and the inner edge of the inlet / outlet interface 11 refers to its edge facing the heated space of the heating device. The flow channel hole passes through both ends of the faucet body 3, allowing fluid to flow from one end of the faucet body 3 to the other end, that is, the fluid can pass through the insertion part 31 and the connecting part 32. The limiting member 33 is provided on the outer wall of the faucet body 3. When the insertion part 31 is installed in the inlet / outlet interface 11 of the heating device, the limiting member 33 can limit the height of the insertion part 31, preventing the height of one end of the insertion part 31 extending into the inlet / outlet interface 11 from being difficult to adjust, causing the fluid flow of the insertion part 31 to be blocked. The blocking member 34 is at one end of the insertion part 31, which is used to lock into the inside of the inlet / outlet interface 11 of the heating device, preventing the faucet body 3 from being easily pulled out after assembly. Therefore, the limiting member 33 and the blocking member 34 together limit the insertion and removal position of the faucet body 3 from the inlet / outlet interface 11.

[0036] In the disassembly and assembly structure, the plug-in part 31 is the main body that extends into the inlet / outlet interface 11. The limiting members 33 and blocking members 34 at both ends of the plug-in part 31 can extend horizontally to restrict the water nozzle body 3 to the inlet / outlet interface 11. It should be noted that the blocking member 34 only extends a short distance horizontally to avoid increasing the difficulty of plugging in. The inlet / outlet interface 11 can be lengthened in the height direction, such as by using rubber and metal vulcanization, welding, casting, or bonding, to form an extension in the height direction of the inlet / outlet interface 11 and fit between the limiting member 33 and the blocking member 34. On this basis, the limiting member 33 can also be a pin, rivet, or bolt, so that the water nozzle body 3 can be detachably installed at the inlet / outlet interface 11 through the limiting member 33. Alternatively, a bracket can be installed to press the limiting member 33 into the inlet / outlet interface 11.

[0037] The water tap body 3 of this application is detachably mounted on the inlet / outlet interface 11 of the heating device via a blocking member 34 and a limiting member 33. This facilitates easy disassembly and replacement of the water tap body 3, making subsequent water tap maintenance convenient. Simultaneously, the limiting member 33 and the blocking member 34 are secured to the inlet / outlet interface 11, ensuring the water tap's sealing performance and allowing for easy replacement of different water taps for different products. Furthermore, the cylindrical water tap, after being welded to the inlet / outlet interface 11, is prone to various problems during transportation. The water tap is susceptible to collisions during transport, leading to bending and deformation, which not only affects the product's appearance but may also impair its normal function. Additionally, the protruding welded water tap in existing products makes packaging inconvenient, increasing packaging costs and transportation risks.

[0038] like Figure 3 and Figure 4 As shown, the limiting member 33 is integrally formed with the connecting part 32 and / or the blocking member 34 is integrally formed with the insertion part 31. The limiting member 33 and the blocking member 34 can be welded to the connecting part 32 and the insertion part 31 respectively, or they can be integrally formed. This application preferably adopts the integral forming setting, which can not only ensure the accurate position of the limiting member 33 and the blocking member 34 and avoid positional displacement caused by welding, which would affect the tightness of the installation, but also reduce the production cost as much as possible by directly drawing the material through a mold.

[0039] like Figure 3 and Figure 4 As shown, the blocking member 34 includes a blocking part 341, which is disposed at the end of the insertion part 31 and protrudes from the outer wall of the insertion part 31. The blocking part 341 is at one end of the insertion part 31 and is engaged with the limiting member 33 at the inlet / outlet interface 11 of the heating device. The blocking part 341 can be configured as a horizontal step surrounding the insertion part 31 so that the blocking part 341 and the limiting member 33 can work together to achieve the effect of limiting and sealing.

[0040] like Figure 3 and Figure 4 As shown, in one embodiment of this application, at least one stepped barrier 341 is provided at the end of the plug-in portion 31, which is evenly distributed along the axis of the plug-in portion 31. Alternatively, a single barrier may be provided only on the outer wall of the plug-in portion 31. In this application, two sets of steps are preferably provided to ensure that the plug-in portion 31 and the limiting member 33 can work together to achieve the effects of limiting and sealing.

[0041] like Figure 3 and Figure 4As shown, in one embodiment of this application, the blocking member 34 includes a guide portion 342, which is disposed at the end of the insertion portion 31 and is obliquely disposed on the outer periphery of the end face of the insertion portion 31. The guide portion 342 is an arc surface or an inclined surface disposed on the outer periphery of the end face of the insertion portion 31. When the guide portion 342 extends into the inlet / outlet interface 11, the inclined surface or arc surface can guide the water nozzle body 3, making it easier for the water nozzle body 3 to extend into the inlet / outlet interface 11 and improving the convenience of detachable installation.

[0042] In this application, the guide portion 342 and the barrier portion 341 are integrally formed to form a blocking member 34, and the blocking member 34 is strip-shaped. The strip-shaped blocking member 34 is evenly distributed at the end of the insertion portion 31. Alternatively, the guide portion 342 and the barrier portion 341 can also directly form an annular blocking member 34. The annular blocking member 34 can improve the sealing of the water nozzle body 3 and the inlet / outlet interface 11. However, because the annular area is large, the force required to insert it into the inlet / outlet interface 11 is large. Therefore, this application preferably uses a strip-shaped blocking member 34.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment of this application, the faucet body 3 is cylindrical, L-shaped, or T-shaped; the shape is composed of a cylindrical insertion part 31 and a connecting part 32. The cylindrical insertion part 31 in this application is only one type, and it can also be changed to an insertion part 31 with a polygonal cross-section. The specific requirements can be set according to the product requirements.

[0044] like Figure 4 As shown, in one embodiment of this application, the faucet body 3 is L-shaped, that is, the axis of the insertion part 31 is perpendicular to the axis of the connecting part 32. The insertion part 31 and the connecting part 32 are preferably integrally formed. In this case, the insertion part 31 and the connecting part 32 can act as elbows. The insertion part 31 is detachably installed on the inlet / outlet interface 11 through the blocking member 34 and the limiting member 33. One end of the connecting part 32 is connected to the water pipe. The pipeline setting of the product can be changed according to the needs of different products to improve the utilization of space. The faucet body 3 can also be T-shaped, that is, the middle part of the connecting part 32 is located at the end of the insertion part 31, and the insertion part 31 can flow into or out of the water body from both ends of the connecting part 32. The inlet and outlet of the connecting part 32 can be adjusted by using plugs. The specific use is similar to that of the L-shaped one, and will not be repeated here. In addition, the faucet body 3 can also be bent into an arc, a broken line, a U-shape or a Y-shape according to the direction of water flow in the pipeline and the water outlet needs of the pipeline.

[0045] like Figure 3 and Figure 4As shown, the limiting member 33 is at least one boss protruding from the outer wall of the insertion part 31. When the limiting member 33 is a boss, multiple limiting members 33 can be provided. Specifically, they can be evenly arranged around the axis of the insertion part 31, and the ends of the multiple bosses facing the inlet / outlet interface 11 are all on the same reference plane. In addition, the limiting member 33 can also be set as an annular boss that protrudes entirely from the outer wall of the insertion part 31, so as to completely cover the gap of the inlet / outlet interface 11 and improve the sealing performance.

[0046] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a heating device is provided, which is equipped with the aforementioned detachable water nozzle. The heating device includes a heating module 1 and a heating element 4. The heating element 4 is disposed on one side of the heating module 1. The heating module 1 includes a fluid channel and inlet / outlet interfaces 11 opened at both ends of the fluid channel. A plug-in portion 31 is detachably sealed to the inlet / outlet interface 11. The flow channel hole of the plug-in portion 31 is connected to the fluid channel of the heating device.

[0047] The heating element 4 is attached and installed on one side wall of the heating module 1. The heating element 4 can be an electric heating tube. The electric heating tube generates heat when energized and transfers the heat to the heating device. After the heating device is heated, it transfers the heat to the fluid channel. The inlet and outlet ports 11 at both ends of the fluid channel are used to supply water or discharge water, so that water can flow into the fluid channel from the water nozzle body 3 at one end. After the water is heated through the fluid channel, it flows out from the water nozzle body 3 at the other end.

[0048] like Figure 5 and Figure 6 As shown, the inlet / outlet 11 of the heating device is detachably fitted with a seal 2. A limiting member 33 and a blocking member 34 are respectively engaged and sealed on both sides of the seal 2. The seal 2 preferably uses an I-shaped sealing gasket. The protrusion of the limiting member 33 is close to the top of the seal 2, while the blocking part 341 of the blocking member 34 is embedded in the inner edge of the bottom of the seal 2. Since there is a slight pressure inside the fluid channel, the pressure will drive the blocking part 341 to abut against the bottom of the seal 2, which can further improve the sealing performance between the water tap body 3 and the seal 2. In addition, the blocking part 341 abuts against the seal 2, and the blocking member 34 and the heated surface of the fluid channel are separated, so that the blocking part 341 and the bottom of the fluid channel are separated from each other, preventing the heat of the heating element 4 from being transferred to the insertion part 31. If the water tap body 3 is made of plastic material, it is easy to cause deformation or melt risk of the water tap body 3, and it is also easy to accelerate the aging and deformation of the seal 2.

[0049] This application includes the following advantages: the limiting member 33 can limit the height of the insertion part 31, preventing the insertion part 31 from being difficult to adjust in terms of height when it extends into the inlet / outlet interface 11, thus avoiding blockage of fluid flow in the insertion part 31; the blocking member 34 is snapped into the inside of the inlet / outlet interface 11 of the heating device, preventing the water nozzle body 3 from being easily pulled outwards after assembly; the limiting member 33 and the blocking member 34 together limit the insertion / removal position of the water nozzle body 3 from the inlet / outlet interface 11; the blocking member 34 only extends a small distance in the horizontal direction to avoid increasing the difficulty of insertion; the inlet / outlet interface 11 can be lengthened in the height direction, such as by using rubber and metal vulcanization, welding, casting, or bonding. In this way, the limiting component 33 and the blocking component 34 ensure the sealing performance of the water nozzle and facilitate the replacement of different water nozzles according to different products, reducing the overall transportation cost and risk. The limiting component 33 and the blocking component 34 are both integrally molded, which can ensure the accurate positioning of the limiting component 33 and the blocking component 34 and avoid positional deviation caused by welding, which would affect the tightness of the installation. At the same time, it can also reduce production costs as much as possible by directly drawing the material through a mold. The blocking component 34 includes a blocking part 341, which is set as a horizontal step surrounding the insertion part 31. The insertion part 31 and the limiting component 33 work together to limit and seal the water nozzle.

[0050] In the heating device, the boss of the limiting member 33 and the blocking part 341 of the blocking member 34 further improve the sealing performance between the water nozzle body 3 and the seal 2. At the same time, the blocking part 341 abuts against the seal 2 and is separated from the bottom of the fluid channel, preventing the heat of the heating element 4 from being transferred to the insertion part 31, causing the insertion part 31 to rise in temperature. Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time.

[0051] A household appliance is equipped with the aforementioned heating device, wherein the heating device is applicable to non-potable water household appliances such as floor scrubbers, garment steamers, washing machines, and dishwashers.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
