Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, and more specifically to a gas-liquid discharge structure and a cleaning machine. Background Art

[0002] When cleaning products on the market, such as floor scrubbers, carpet cleaners, and fabric cleaners, are working, the fan in the machine rotates to generate airflow to carry the garbage and sewage on the ground into the garbage collector, and then discharges the airflow. In this process, a small amount of moisture contained in the airflow will also enter the machine, which can easily cause the electronic components inside the machine to get damp; at the same time, the airflow runs around inside the machine, resonating with the inner wall of the machine, causing the machine noise to increase.

[0003] In order to reduce the noise during the airflow discharge process, Chinese patent number CN203458330U discloses a vacuum cleaner and an exhaust device thereof, wherein the exhaust device is arranged downstream of the motor cover of the vacuum cleaner and is connected to the motor cover through an air outlet on the motor cover. The exhaust device comprises: an exhaust cover, wherein the exhaust cover defines an exhaust passage, wherein the exhaust passage is connected to the motor cover through the air outlet and is connected to the outside through the air outlet, wherein the cross-sectional area of ​​the exhaust passage gradually increases in a direction away from the air outlet; and a filter element, wherein the filter element is connected to the exhaust cover and is arranged at the air outlet. However, although this prior art adopts an exhaust channel with a gradually increasing cross-sectional area to slow down the air flow speed and thus achieve the purpose of reducing noise, its exhaust port is behind the fan, and the air flow will be discharged to the user during vacuuming, affecting the user experience; in addition, when the vacuum cleaner is working, the air flow will flow through the entire fan. If there is moisture in the air flow, it will easily affect the normal operation of the motor, and the air volume may be reduced and the noise may increase. In severe cases, the fan may even be destroyed. It can be seen that this exhaust device is only suitable for products with dry air flow without moisture. Utility Model Content

[0026] Reference Figure 1-4 A gas-liquid discharge structure and a cleaning machine according to an embodiment of the utility model are described.

[0027] In one embodiment, Figure 1-3As shown, a gas-liquid discharge structure includes a fan assembly 1 and a gas-liquid discharge channel 2, the fan assembly 1 includes a shell and a dust suction fan, the inner cavity of the shell is divided into an upper cavity and a lower cavity isolated from each other, the dust suction fan includes a motor part 13 and a fan part 14; the motor part 13 is arranged in the upper cavity, and the fan part 14 is arranged in the lower cavity; an air flow inlet 15 is provided at the bottom center of the lower cavity and an air flow outlet 16 is provided downwardly on one side of the bottom, the air flow inlet 15 is communicated with the air inlet side of the fan part 14, and the air flow outlet 16 is communicated with the air outlet side of the fan part 14; the air flow outlet 16 is downwardly connected to one end of the gas-liquid discharge channel 2, and the other end of the gas-liquid discharge channel 2 extends downward until it is communicated with a gas-liquid discharge pipe 22 located at the bottom of the cleaning machine 100, the lower end of the gas-liquid discharge pipe 22 is a gas-liquid discharge outlet 23, and the gas-liquid discharge outlet 23 is arranged on the bottom surface of the cleaning machine 100.

[0028] The housing includes an upper shell 11 and a lower shell 12, wherein the lower shell 12 is connected to the bottom of the upper shell 11; a through hole is provided at the center of the bottom of the upper shell 11 around the upper end surface of the fan part 14, and the inner wall of the upper shell 11 and the upper end surface of the fan part 14 form an upper cavity; the inner wall of the lower shell 12 and the bottom surface of the bottom of the upper shell 11 form a lower cavity. The upper shell 11 and the lower shell 12 together form a lower cavity, in which there is only the fan part 14, so that the motor part 13 of the dust suction fan is completely isolated from the fan part 14, and the contact between the water-containing airflow and the motor part 13 can be avoided, effectively preventing moisture from affecting the operation of the motor part 13, and having better waterproof performance.

[0029] Reference below Figure 1-3 The working process of the gas-liquid discharge structure of this embodiment is described in detail.

[0030] First, the fan part 14 rotates under the drive of the motor part 13, generating negative pressure in the lower chamber and sucking air into the lower chamber. Figure 1 and Figure 3 As shown by the middle arrow, the airflow is sucked into the lower chamber by the fan part 14 at the airflow inlet 15 at the center of the bottom of the lower chamber, and then flows from the air inlet side of the fan part 14 to the air outlet side, and then flows into the gas-liquid discharge channel 2 below from the airflow outlet 16, flows downward along the gas-liquid discharge channel 2 to the gas-liquid discharge pipe 22, and finally flows out from the gas-liquid discharge outlet 23. Since the gas-liquid discharge channel 2 is vertically arranged from top to bottom, a sufficiently long air duct is formed, making the airflow flow more stable, thereby reducing the noise pollution caused by the collision and friction between the airflow and the inner wall of the machine, and thus effectively reducing the working noise of the machine. In addition, since the gas-liquid discharge outlet 23 is arranged on the bottom surface of the cleaning machine 100, the airflow is finally discharged from the bottom of the machine to the ground, which will not affect the user.

[0031] In this embodiment, a first sealing ring 17 is provided between the fan part 14 and the bottom surface of the bottom plate of the upper shell 11, and a second sealing ring 18 is provided between the motor part 13 and the inner wall of the lower shell 12, which can ensure the sealing of the lower cavity and prevent the water-containing airflow from entering the upper cavity where the motor part 13 is located.

[0032] In this embodiment, at least one heat dissipation opening 19 is provided on the side surface of the upper shell 11 to facilitate heat dissipation of the fan part 14 .

[0033] In this embodiment, a gas-liquid discharge section 21 is provided at one end of the gas-liquid discharge channel 2 close to the gas-liquid discharge port 23, and the inner diameter of the gas-liquid discharge section 21 is smaller than the inner diameter of the main part of the gas-liquid discharge channel 2; the lower end of the gas-liquid discharge section 21 is inserted into the upper end of the gas-liquid discharge pipe 22.

[0034] In specific implementation, a small amount of moisture remains in the airflow discharged from the fan part 14. This moisture condenses into small water droplets when it is cold in the gas-liquid discharge section 21 of the gas-liquid discharge channel 2, and flows out of the gas-liquid discharge port 23 along the gas-liquid discharge pipe 22 under the action of gravity.

[0035] In this embodiment, the outer wall of the gas-liquid discharge channel 2 may be wrapped with a sound insulation layer.

[0036] In this embodiment, a sound insulation layer can be provided on the outer wall of the gas-liquid discharge channel 2 to achieve further noise reduction function and enhance the user experience.

[0037] In another embodiment, Figure 4 As shown, the utility model provides a cleaning machine 100, which includes a gas-liquid discharge structure as in any of the above embodiments.

[0038] The cleaning machine 100 in the present technology adopts the above-mentioned gas-liquid exhaust structure, which can effectively prevent the electronic components inside the machine from getting damp and reduce product noise.

[0039] In this embodiment, the above-mentioned cleaning machine 100 also includes a filter component 101, a gas-liquid separation component 102 and a sewage collection box 103 connected in sequence from top to bottom; the air inlet end of the gas-liquid separation component 102 is connected to the dust suction port of the cleaning machine 100 through a dust suction pipe, and the air outlet end of the gas-liquid separation component 102 is connected to the air flow inlet 15 through the filter component 101.

[0040] During the operation of the cleaning machine 100, the garbage and sewage in the airflow sucked into the dust suction port are first separated into the sewage collection box 103 through the gas-liquid separation component 102, and then the separated airflow is filtered by the filter component 101 and enters the air inlet side of the fan part 14 through the airflow inlet 15 provided at the bottom of the lower shell 12. The gas-liquid separation component 102 can remove most of the moisture in the airflow, so that the airflow entering the fan contains only a small amount of moisture, and the filter component 101 further filters the dust in the airflow to play a dust-proof role.

[0041] The gas-liquid discharge structure and other structures and operations of the cleaning machine 100 according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
