Description

Technical Field

[0001] The present invention relates to the field of household cleaning equipment, and in particular to a self-cleaning base for a floor scrubber. Background Art

[0002] Floor scrubbers are a common household cleaning device, widely used to clean surfaces such as floors and carpets. After cleaning the floor, existing floor scrubbers need to be placed on a base for self-cleaning. However, existing bases often have the following problems:

[0003] 1. Inadequate cleaning effect: Existing bases generally only clean the roller brush of the floor scrubber by rinsing with clean water or spraying with simple cleaning fluid. This makes it difficult to completely remove stubborn stains on the roller brush and fails to effectively improve cleaning efficiency.

[0004] 2. Single function: Existing bases often lack a drying function, so the roller brush is prone to breeding bacteria or producing odor after cleaning, and cannot guarantee cleaning efficiency and hygiene;

[0005] 3. Complex structure: Some existing bases require separate clean water tanks and cleaning liquid storage devices, which results in bulky volume and high cost. Summary of the Invention

[0006] To solve the above problems, the present invention provides a self-cleaning base for a floor scrubber, which solves the problems of poor self-cleaning effect and single function in the prior art by integrating clean water heating, cleaning liquid mixed injection and hot air drying functions, while reducing the volume and cost of the base.

[0007] According to one aspect of the present invention, a self-cleaning base for a floor scrubber is provided, which is used to mount the floor scrubber, and includes a housing, wherein a cleaning liquid reservoir, a jet pump, at least one cleaning liquid nozzle, a clean water connector, a heater, at least one hot water outlet, a fan, and at least one air outlet are provided inside the housing;

[0010] The housing is provided with an air flow channel, the air flow channel is communicated with the air outlet, the heater and the fan are arranged in the air flow channel, and the heater is located between the fan and the air outlet;

[0011] The heater includes a shell, the outside of the shell has a sunken air heating chamber, a water inlet and a water outlet, and the inside has a heating water pipe, the two ends of the heating water pipe are respectively connected to the water inlet and the water outlet, and a portion of the heating water pipe is spirally wrapped around the air heating chamber, and a plurality of radial heating fins are arranged on the outside of the shell and / or the inside of the air heating chamber, each of the radial heating fins extends toward the center of the circle, and the plurality of radial heating fins are arranged at intervals along the circumferential direction.

[0012] In some embodiments, a vertical connector bracket is mounted on the top front side of the housing, and the top of the housing is also provided with multiple protruding engaging structures, each of which has a top end in the form of a boss and / or a groove. Advantageously, the connector bracket and the engaging structures can be used to stably position the scrubber.

[0013] In some embodiments, the clean water connector is disposed on one of the snap-fit ​​structures and is exposed outside the housing. This is advantageous in that the clean water connector can be smoothly docked with a corresponding clean water tank connector on the floor scrubber.

[0014] In some embodiments, at least one vent is provided on the front side of the housing, which is beneficial in that the vent can be used to ensure ventilation of the base.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, the base includes a housing 1, with a vertical connector bracket 11 mounted on the top front of the housing 1. The connector bracket 11 is used to support and charge the floor scrubber. The top of the housing 1 is also provided with multiple protruding engaging structures 12 for positioning the floor scrubber and limiting its movement. The top shape of each engaging structure 12 matches the corresponding structure on the bottom surface of the floor scrubber, and can be a boss and / or a groove.

[0026] In addition, at least one vent 13 is provided on the front side of the housing 1 for ventilation and heat dissipation, and a protruding outlet frame 14 is provided on the rear side of the housing 1 for arranging various nozzles and outlets.

[0027] The interior of the housing 1 is mainly provided with a cleaning liquid reservoir 2, a jet pump 3, at least one cleaning liquid nozzle 4, a clean water connector 5, a heater 6, at least one hot water outlet 7, a fan 8 and at least one air outlet 9.

[0028] The cleaning liquid reservoir 2 is connected to the jet pump 3 via a pipeline, and the jet pump 3 is also connected to the cleaning liquid nozzle 4 via a pipeline. The cleaning liquid reservoir 2 is used to store cleaning liquid, and the cleaning liquid nozzles 4 are mounted on the front side of the outlet frame 14 and face the roller brush of the floor scrubber. As a result, the cleaning liquid stored in the cleaning liquid reservoir 2 can be sprayed through the cleaning liquid nozzles 4 under the action of the jet pump 3, thereby cleaning the roller brush.

[0029] The clean water connector 5 is connected to the heater 6 via a pipe, and the heater 6 is connected to the hot water outlet 7 via a pipe. The hot water outlet 7 is mounted on the front side of the outlet frame 14 and faces the roller brush of the floor scrubber. Therefore, the clean water introduced by the clean water connector 5 is heated by the heater 6 and then sprayed out from the hot water outlet 7 to clean the roller brush.

[0030] The clean water connector 5 can be set on one of the (generally recessed) snap-fit ​​structures 12 and exposed on the outside of the shell 1. When the floor scrubber is placed on the base, the clean water connector 5 can be docked with the connector of the corresponding clean water tank on the floor scrubber, and the clean water in the clean water tank in the floor scrubber can be directly used, thereby avoiding the need to set up a water tank on the base again, reducing costs, and reducing the volume of the base.

[0031] The housing 1 also has an airflow channel (not shown). A heater 6 and a fan 8 are located within the channel, with the heater 6 positioned between the fan 8 and the air outlet 9. The channel is also connected to the air outlet 9, which is mounted on the front side of the outlet frame 14 and faces the scrubber's roller brush. Consequently, hot air heated by the heater 6 is ejected from the air outlet 9 by the fan 8, cleaning the roller brush.

[0032] like Figure 3 As shown, the heater 6 includes a shell 61, the outside of which is formed with a sunken air heating chamber 62, a water inlet 63 and a water outlet 64, and the inside of the shell 61 is provided with a heating water pipe (not shown in the figure), wherein the heating water pipe includes a water pipe and a heating pipe that are closely attached to each other, and the two ends of the heating water pipe are respectively connected to the water inlet 63 and the water outlet 64, and a part of the heating water pipe surrounds the air heating chamber 62.

[0033] The water inlet 63 is connected to the clean water connector 5 through a pipeline, and the water outlet 64 is connected to the hot water outlet 7. Therefore, the clean water introduced by the clean water connector 5 enters the heater 6 through the water inlet 63, and after being heated by the heating water pipe, it flows from the water outlet 64 to the hot water outlet 7, and at the same time can heat the cold air in the air heating chamber 62. The heated cold air is then ejected from the air outlets 9 under the action of the fan 8.

[0034] Preferably, the air heating chamber 62 is circular, providing a symmetrical heating environment that evenly distributes heat and reduces localized overheating or cold spots. Furthermore, preferably, the air heating chamber 62 is narrow in the middle to suppress low-frequency pressure fluctuations, and gradually expands as it extends toward the water inlet 63 and outlet 64, diffusing and reducing high-frequency turbulent noise at the inlet and outlet, thereby reducing airflow noise.

[0035] Preferably, the heating water pipe is spirally wrapped around the air heating chamber 62.

[0036] Preferably, a receiving space (not shown in the figure) is formed inside the shell 61, and part of the heating water pipe surrounding the air heating cavity 62 is located in the receiving space.

[0037] In addition, a plurality of radial heating fins 65 may be provided on the outside of the shell 61 and inside the air heating chamber 62 to increase the contact area between the heater 6 and the air and improve the cold air heating efficiency.

[0038] Preferably, the radial heating fins 65 extend toward the center of the circle, and multiple radial heating fins 65 are arranged at intervals along the circumferential direction. Thus, not only can multiple radial heating fins 65 be arranged in the smallest possible space to increase the heat exchange area and improve the heating efficiency, but the heat exchange efficiency and fluid resistance can also be balanced to avoid excessive pressure loss due to dense arrangement.

[0039] It can be seen that when using the base, as described in the above embodiment, cleaning liquid, heated hot water and hot air can be sprayed out from the cleaning liquid nozzles 4, the hot water outlets 7 and the air outlets 9 respectively to clean the roller brush.

[0040] In addition, the present invention also provides another embodiment, in which the structure of the base is roughly the same as that of the previous embodiment, except that the water outlet 64 of the heater 6 is connected to the cleaning liquid storage 2 through a pipeline. The hot water heated by the heater 6 can be mixed with the cleaning liquid in the cleaning liquid storage 2 and then enter the jet pump 3. When the jet pump 3 is operated, the hot water mixed with the cleaning liquid can be sprayed from the cleaning liquid nozzle 4, thereby cleaning the roller brush.

[0041] The self-cleaning base of a floor scrubber in the present invention mainly has the following beneficial effects:

[0042] 1. Improved cleaning effect: Hot water and cleaning liquid work together to effectively decompose oil and stubborn stains on the roller brush;

[0043] 3. Enhanced hygiene: With hot air drying function, it prevents the growth of bacteria on the roller brush in a humid environment;

[0044] 3. High heat exchange efficiency: The heater is equipped with an air heating chamber, a heating water pipe and multiple sets of heat sinks, which significantly improves the heating efficiency of water and air.

[0045] 4. Integrated design: By sharing the clean water tank of the floor scrubber, the internal water tank setting of the base is eliminated, reducing the volume and cost.

[0046] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
