Abstract
Description
Technical Field
[0001] This application relates to the field of electrical equipment, and more particularly to a steam mop. Background Technology
[0002] Steam mops primarily rely on a steam generator to heat water into steam. The steam is then released through pipes to locations such as the floor, windows, and kitchen countertops. The working interface of a normal steam generator is its boiling surface. Water falls onto the boiling surface, is heated and vaporized, and then released to the outside. In related technologies, a certain amount of water needs to be stored after free fall to reach the boiling surface for heating. As a result, there are problems with low heating efficiency and the inability to quickly generate continuous steam. Summary of the Invention
[0003] In view of this, the present application aims to provide a steam mop with high heating efficiency and the ability to quickly generate continuous steam.
[0004] To achieve the above objectives, embodiments of this application provide a steam mop, comprising:
[0005] body;
[0006] A floor mop located at one end of the body;
[0007] A steam generator is installed in the body of the steam mop. The steam generator includes a housing with a water inlet and a heating element disposed within the housing. The heating element has a boiling surface. When the steam mop is in a horizontal working state with the steam outlet direction parallel to the horizontal plane, the steam generator is in an inclined state. The angle α between the extension line of the steam generator along the height direction and the horizontal plane satisfies the following: when the steam mop is in the working state, the water flow injected into the housing from the water inlet can fall onto the boiling surface under its own gravity. The working state includes at least a downward tilting working state and the horizontal working state. When the steam mop is in the downward tilting working state, the body is in an inclined state and the mop is located at the lower end of the body along the tilting direction.
[0008] In one embodiment, the working state further includes an upward working state, in which the steam mop is in the upward working state, the body is in an inclined state and the mop is located at the upper end of the body along the inclined direction.
[0009] In one embodiment, when the steam mop is in the horizontal working state, the steam generator tilts downward from the end closer to the mop toward the end farther away from the mop.
[0010] In one embodiment, the included angle α is greater than 0° and less than or equal to 45°.
[0011] In one embodiment, the included angle α is 15°-30°.
[0012] In one embodiment, the heating element has a secondary heating channel, the axis of which extends along the height direction of the steam generator.
[0013] In one embodiment, the steam mop further includes a steam outlet nozzle disposed in the body, the steam outlet nozzle having a steam outlet channel, and when the steam mop is in the horizontal working state, the axis of the steam outlet channel is parallel to the horizontal plane.
[0014] In one embodiment, when the steam mop is in the horizontal working state, the tilt direction of the boiling surface is consistent with the tilt direction of the steam generator, and the water inlet is located on the upper side of the outer casing along the tilt direction.
[0015] In one embodiment, the boiling surface is located on the side of the heating core near the water inlet, and when the steam mop is in the horizontal working state, the water inlet is located on the upper side of the heating core.
[0016] In one embodiment, the heating element has a water inlet channel and a boiling tank. The boiling tank is provided at least one end of the water inlet channel at opposite ends along its extension direction. The water inlet is connected to the water inlet channel, and the water inlet channel is connected to the boiling tank. The bottom surface of the boiling tank is the boiling surface.
[0017] In one embodiment, when the steam mop is in the horizontal working state, the height of the boiling surface is lower than the height of the bottom surface of the water inlet channel.
[0018] In one embodiment, when the steam mop is in operation, the projection range of the water inlet along the vertical direction onto the horizontal plane is located within the projection range of the boiling surface.
[0019] This application provides a steam mop, which includes a body, a mop, and a steam generator. When the steam mop is in a horizontal working state with the steam outlet direction parallel to the horizontal plane, the steam generator is tilted. The angle α between the extension line of the steam generator along the height direction and the horizontal plane satisfies the following: When the steam mop is in working state, the water flow injected into the outer shell from the water inlet can fall onto the boiling surface of the steam generator under its own gravity. Thus, when the steam mop is in working state, regardless of whether the steam generator is in a downward tilting working state or a horizontal working state, the water flow injected into the outer shell from the water inlet can fall onto the boiling surface of the steam generator under its own gravity. This allows the water flow falling onto the boiling surface to be heated and vaporized by the boiling surface, thereby enabling the steam mop to quickly generate continuous steam.

Detailed Implementation
[0031] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.
[0032] This application provides a steam mop; please refer to [link / reference]. Figures 1 to 8The steam mop includes a body 10, a floor mop 20, and a steam generator 30. The floor mop 20 is located at one end of the body 10. The steam generator 30 is located in the body 10 and includes a housing 31 with a water inlet 31a and a heating element 32 located in the housing 31. The heating element 32 has a boiling surface 32a. When the steam mop is in a horizontal working state with the steam outlet direction parallel to the horizontal plane, the steam generator 30 is in an inclined state. The angle α between the extension line of the steam generator 30 along the height direction and the horizontal plane satisfies the following: when the steam mop is in the working state, the water flow injected into the housing 31 from the water inlet 31a can fall onto the boiling surface 32a under its own gravity. The working state includes at least a downward tilting working state and a horizontal working state. When the steam mop is in the downward tilting working state, the body 10 is in an inclined state and the floor mop 20 is located at the lower end of the body 10 along the tilting direction.
[0033] Specifically, steam mops generally have a floor mopping mode and a handheld mode. The steam mop in this embodiment has at least two working states: a downward tilting working state and a horizontal working state. Please refer to [link / reference]. Figure 2 When the steam mop is in floor mopping mode, the steam mop is in a downward tilting working state, the body 10 is tilted, and the floor mop 20 is located at the lower end of the body 10 along the tilting direction. In floor mopping mode, the body 10 is generally at a certain angle b with the ground. For example, b can range from 45° to 60°. When the steam mop is in handheld mode, the steam mop can be in either a downward tilting working state or a horizontal working state. Please refer to [link / reference needed]. Figure 2 In handheld mode, the steam mop tilts downwards in the same way as in floor mopping mode, with the body 10 at a certain angle b to the ground.
[0034] In related technologies, steam generators are typically installed vertically or horizontally within the machine body. When the steam mop is in a horizontal working state with the steam outlet direction parallel to the horizontal plane, the angle between the extension line of the steam generator along the height direction and the horizontal plane is 0° or 90°. Water injected into the outer casing from the inlet needs to reach a certain storage volume after free fall before it can reach the boiling point for heating. This results in problems such as low heating efficiency, slow heating reaction speed, discontinuous steam, and low temperature in the steam mop.
[0035] The steam mop provided in this application embodiment, when the steam mop is in a horizontal working state where the steam outlet direction is parallel to the horizontal plane, please refer to... Figure 3The steam generator 30 is tilted, and the angle α between the extension of the steam generator 30 along its height and the horizontal plane satisfies the following: When the steam mop is in operation, the water flowing into the outer casing 31 from the inlet 31a can fall onto the boiling surface 32a of the steam generator 30 under its own gravity. Therefore, when the steam mop is in operation, regardless of whether the steam generator 30 is in a downward tilting or horizontal operating state, please refer to... Figure 2 and Figure 3 The water flowing into the outer casing 31 from the inlet 31a can fall onto the boiling surface 32a of the steam generator 30 under its own gravity, thereby heating and vaporizing the water flowing onto the boiling surface 32a, which in turn enables the steam mop to quickly generate continuous steam.
[0036] In one embodiment, the operating state also includes an upward-lifting operating state; please refer to [link to relevant documentation]. Figure 4 When the steam mop is in the upward working state, the body 10 is in an inclined state and the mop 20 is located at the upper end of the body 10 along the inclined direction.
[0037] Specifically, when the steam mop is in handheld mode, it can also be in an upward-lifting working state; please refer to [link / reference]. Figure 4 When the steam mop is in the upward working state, the body 10 is in an inclined state and the mop 20 is located at the upper end of the body 10 along the inclined direction.
[0038] Please see Figures 1 to 4 In this embodiment, regardless of whether the steam mop is in a downward working state, an upward working state, or a horizontal working state, the water flow injected into the outer shell 31 from the water inlet 31a can fall onto the boiling surface 32a of the steam generator 30 under its own gravity. That is, the steam mop provided in this embodiment can improve the steam generation efficiency in two different working states: floor mopping mode and handheld mode, and can improve the vaporization effect of steam.
[0039] In one embodiment, when the steam mop is in a horizontal working position, please refer to... Figure 3 The steam generator 30 is tilted downwards from the end closer to the mop 20 to the end farther away from the mop 20. This arrangement allows the water flowing into the housing 31 from the inlet 31a to fall onto the boiling surface 32a of the steam generator 30 under its own gravity.
[0040] In one implementation, please refer to Figure 5 and Figure 7 The heating element 32 has a secondary heating channel 321, the axis of which extends along the height direction of the steam generator 30.
[0041] For details, please refer to Figure 5 and Figure 7 The heating element 32 has a secondary heating channel 321 that runs through the heating element 32. The beginning of the secondary heating channel 321 along the steam flow direction is connected to the end of the steam flow channel along the steam flow direction. The end of the secondary heating channel 321 along the steam flow direction forms a steam outlet. In other words, the steam in the steam flow channel can also be heated twice in the heating element 32 before being ejected from the steam outlet. This can improve the steam dryness on the one hand, and keep the steam outlet temperature at a high temperature on the other hand.
[0042] In one embodiment, please refer to Figure 3 and Figure 9 The steam mop also includes a steam outlet 33 disposed in the body 10. The steam outlet 33 has a steam outlet channel 33a. When the steam mop is in a horizontal working state, the axis of the steam outlet channel 33a is parallel to the horizontal plane.
[0043] For details, please refer to Figure 3 The steam nozzle 33 is connected to the steam outlet of the steam generator 30 through a pipe. When the steam mop is in a horizontal working state, the axis of the steam outlet channel 33a of the steam nozzle 33 is parallel to the horizontal plane. That is to say, steam is sprayed out from the steam nozzle 33 located in the middle of the mop 20. This setting position can improve the efficiency of steam and is suitable for steam mops that need to directly aim the steam outlet at the ground.
[0044] In one embodiment, the included angle α is greater than 0° and less than or equal to 45°. Since the axis of the steam outlet channel 33a of the steam outlet 33 is parallel to the horizontal plane, and the steam outlet 33 is connected to the steam outlet of the steam generator 30 through a connecting pipe, the included angle α is greater than 0° and less than or equal to 45°. This allows the water flowing from the inlet 31a into the outer shell 31 to fall onto the boiling surface 32a of the steam generator 30 under its own gravity, while also facilitating the connection between the steam outlet 33 and the steam outlet. Preferably, the included angle α is 15°-30°.
[0045] In one embodiment, when the steam mop is in a horizontal working state, the tilt direction of the boiling surface 32a is consistent with the tilt direction of the steam generator 30, and the water inlet 31a is located on the upper side of the outer casing 31 along the tilt direction.
[0046] Specifically, when the steam mop is in a horizontal working state with the steam outlet direction parallel to the horizontal plane, the steam generator 30 is tilted, and the boiling surface 32a of the steam generator 30 is also tilted at a certain angle to the horizontal plane. The water inlet 31a is located on the upper side of the outer shell 31 along the tilt direction, so that the water flow injected into the outer shell 31 from the water inlet 31a can fall onto the boiling surface 32a under its own gravity. The tilt direction of the boiling surface 32a is consistent with the tilt direction of the steam generator 30, which means that the boiling surface 32a and the steam generator 30 tilt in the same direction. The tilt angles of the two can be the same or different.
[0047] In one embodiment, the boiling surface 32a is located on the side of the heating core 32 near the water inlet 31a. When the steam mop is in a horizontal working state, the water inlet 31a is located on the upper side of the heating core. That is to say, the water flowing into the outer casing 31 from the water inlet 31a enters the heating core 32 under its own gravity and can fall onto the boiling surface 32a as quickly as possible, thereby improving the heating efficiency of the steam mop.
[0048] In one embodiment, please refer to Figures 6 to 8 The heating element 32 has a water inlet channel 32b and a water boiling tank 32c. Water boiling tanks 32c are provided at both ends of the water inlet channel 32b along the extension direction. The water inlet 31a is connected to the water inlet channel 32b and the water inlet channel 32b is connected to the water boiling tank 32c. The bottom surface of the water boiling tank 32c is the boiling surface 32a.
[0049] Please see Figures 6 to 8 The steam generator 30 includes a steam outlet, a housing 31, and a heating element. The housing 31 has a water inlet 31a. The heating element includes a heating core 32 and a heating tube disposed in the heating core 32. A portion of the heating core 32 is disposed in the housing 31, so that a water inlet channel 32b and a water boiling tank 32c are formed in the housing 31 between the heating core 32 and the housing 31. The two water boiling tanks 32c are located on opposite sides of the water inlet channel 32b along its extension direction. The water inlet 31a is connected to the water inlet channel 32b, and the steam outlet is connected to the two water boiling tanks 32c respectively. The bottom surface of the water boiling tank 32c is the boiling surface 32a. That is to say, the water flow injected into the housing 31 from the water inlet 31a enters the heating core 32 through the water inlet channel 32b, and then enters the water boiling tanks 32c on opposite sides of the water inlet channel 32b along its extension direction, so that it can fall onto the boiling surface 32a as soon as possible, thereby improving the heating efficiency of the steam mop.
[0050] Please refer to Figure 8The water inlet channel 32b is provided with boiling tanks 32c at both ends along its extension direction. Thus, no matter which way the water flows into the outer shell 31 from the water inlet 31a enters the water inlet channel 32b, it will enter the boiling tank 32c. This allows the water to flow into the boiling tank 32c as quickly as possible after entering the water inlet channel 32b. The two boiling tanks 32c can heat the water at the same time, thereby improving the heating efficiency of the steam mop.
[0051] Specifically, please refer to Figure 8 In this embodiment, the steam generator 30 is provided with a water inlet channel 32b communicating with the water inlet 31a. Water flows from the water inlet 31a into the water inlet channel 32b, and then from the water inlet channel 32b into the boiling water tank 32c. That is to say, regardless of whether the steam mop is in a downward working state, an upward working state, or a horizontal working state, the water injected into the steam generator 30 can flow into the corresponding boiling water tank 32c along the bottom wall of the water inlet channel 32b. Therefore, the steam generator 30 can continuously generate steam, thereby enabling the steam mop to work normally at multiple angles.
[0052] In some embodiments, a water inlet channel 32b and a water boiling tank 32c are formed on the heating core 32. The water inlet channel 32b is provided at one end along the extension direction of the water boiling tank 32c. The water inlet 31a is connected to the water inlet channel 32b, and the water inlet channel 32b is connected to the water boiling tank 32c. The bottom surface of the water boiling tank 32c is the boiling surface 32a.
[0053] In one embodiment, please refer to Figure 8 The heating element 32 also includes multiple water-hanging components 32d, which are spaced apart in the water-heating tank 32c. The water-hanging components 32d can be either water columns or water plates. They can slow down the flow of water in the corresponding water-heating tank 32c to ensure the water is heated sufficiently.
[0054] In one specific embodiment, please refer to Figures 1 to 9 A steam flow channel is formed between the heating core 32 and the outer shell 31. The steam mop also includes a water tank 40, an electromagnetic pump 50, a steam outlet 33, and a floor mop 20. The water tank 40 is connected to the water inlet 31a through a pipeline. An electromagnetic pump 50 is installed on the pipeline. The heating core 32 has a secondary heating channel 321 that runs through the heating core 32. The beginning of the secondary heating channel 321 along the steam flow direction is connected to the end of the steam flow channel along the steam flow direction. The end of the secondary heating channel 321 along the steam flow direction forms a steam outlet. The steam outlet 33 is connected to the steam outlet of the steam generator 30 through a connecting pipe.
[0055] In one embodiment, when the steam mop is in a horizontal working position, please refer to... Figure 8The boiling surface 32a is set at a height lower than the bottom surface of the water inlet channel 32b. This means that the water tank 32c can hold more water. The water flows into the corresponding water tank 32c along the bottom wall of the water inlet channel 32b and can be stored in the corresponding water tank 32c. The heating element can heat the water in the water tank 32c at the same time, thereby improving the heating efficiency of the steam generator 30.
[0056] In one embodiment, please refer to Figures 1 to 4 When the steam mop is in operation, the projection range of the water inlet 31a in the vertical direction on the horizontal plane is within the projection range of the boiling surface 32a. This arrangement allows the water flowing into the outer casing 31 from the water inlet 31a to fall onto the boiling surface 32a under its own gravity, regardless of the operating state of the steam mop. This allows the water flowing onto the boiling surface 32a to be heated and vaporized, thereby enabling the steam mop to quickly generate continuous steam.
