Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to water tanks and cleaning machines. Background Technology

[0002] Water tanks are commonly used in shower equipment for water storage or temperature control. The tank's inlet connects to the external water system, allowing water to flow into the tank from the outside. In existing shower tank designs, the height difference between the inlet and the bottom of the tank causes noise during water flow, negatively impacting the user experience. Furthermore, some tanks may contain sensors that can misinterpret water flow. Utility Model Content

[0003] Considering the impact of direct water flow, a water guiding structure is installed inside the water tank. This structure can guide and slow down the flow, thus alleviating the problem of water splashing during water supply. However, due to the design of the water guiding structure, as the water level rises, a closed space may form between the water guiding structure, the liquid surface, and the tank wall, causing air to be trapped inside the water tank and affecting the actual water intake.

[0004] Therefore, the main purpose of this utility model is to propose a water tank and a cleaning machine that not only guides the water flow during the introduction of water, so that the water flow in the tank has a small buffering force and low noise when water enters, but also has an exhaust design to ensure the accuracy of the actual water intake of the water tank.

[0005] To achieve the above objectives, this utility model proposes a water tank, comprising:

[0006] A housing, the housing having at least one water chamber, the water chamber having an inlet and an outlet spaced apart in the vertical direction, the outlet for outputting water from the water chamber, and the inlet for allowing an external water source to enter; and...

[0007] At least one water guiding structure is disposed within the water cavity, the water guiding structure extending vertically and at least partially located below the water inlet, and at least one vent hole is formed on the water guiding structure for connecting opposite sides of the water guiding structure.

[0008] In one embodiment, the water guiding structure includes a first water guiding part, at least a portion of which is inclined vertically. The first water guiding part is located below the water inlet, and the first water guiding part is provided with the vent hole to guide the space defined between the two opposite sides of the first water guiding part in the vertical direction and the inner wall of the water cavity.

[0009] In one embodiment, the lower side of the first water guide portion and the inner wall of the water cavity define a protective space for the sensor to be placed.

[0010] The vent on the first water guide is positioned above the sensor to open the protective space.

[0011] In one embodiment, the water guiding structure further includes a second water guiding part, which is located above the water outlet. The second water guiding part is at least partially inclined vertically, and at least partially located below the lower end of the first water guiding part.

[0012] Both the first water guiding part and the second water guiding part are provided with the vent hole.

[0013] In one embodiment, the vent is located at the upper part of the first water guide portion and / or the second water guide portion.

[0014] In one embodiment, the water chamber is provided in two parts, which include a first water chamber and a second water chamber spaced apart in the horizontal direction. The inlet of the first water chamber is used to allow external hot water to enter, and the inlet of the second water chamber is used to allow external room temperature water to enter. The hot water output from the outlet of the first water chamber is used to mix with the room temperature water output from the outlet of the second water chamber.

[0015] A return water outlet is provided between the inlet and outlet of the second water chamber, and the first water guide is provided inside the second water chamber. The lower end of the first water guide extends to the horizontal side of the return water outlet.

[0016] The water guiding structure further includes a third water guiding part disposed in the second water cavity. The third water guiding part extends in the vertical direction and is located on the side of the return water port. The upper end of the third water guiding part is connected to the first water guiding part to divide the first water guiding part into a first mating section and a second mating section. The second mating section is located above the return water port.

[0017] The first mating section is provided with the vent hole to guide the space defined by the walls of the first mating section, the third water guide section and the second water cavity;

[0018] The second mating section is provided with the vent hole to guide the space defined by the second mating section, the third water guide section and the return water port.

[0019] In one embodiment, the water tank further includes a blocking part located between the water guiding structure and the water inlet, the projection of the blocking part on the water guiding structure covering the vent hole.

[0020] In one embodiment, a notch is provided at a local edge of the water-guiding knot to form the vent hole.

[0021] In one embodiment, the tank body is provided with an overflow port communicating with the water cavity, and the overflow port is located in the upper region of the water tank;

[0022] The water guiding structure further includes a fourth water guiding section, which extends in the vertical direction and is located between the overflow port and the inlet port. The vent hole is provided on the fourth water guiding section.

[0023] This utility model also proposes a cleaning machine, comprising:

[0024] Water tank; and,

[0025] A water outlet assembly, one end of which is connected to the water outlet, and the other end of which is connected to the water user.

[0026] The water tank includes at least the following:

[0027] A housing, the housing having at least one water chamber, the water chamber having an inlet and an outlet spaced apart in the vertical direction, the outlet for outputting water from the water chamber, and the inlet for allowing an external water source to enter; and...

[0028] At least one water guiding structure is disposed within the water cavity, the water guiding structure extending vertically and at least partially located below the water inlet, and at least one vent hole is formed on the water guiding structure for connecting opposite sides of the water guiding structure.

[0029] In this invention, water from an external source is introduced through the inlet and, after being guided by the water-guiding structure, falls to the bottom of the water chamber. The water-guiding structure acts as a guide and buffer, preventing the water flow from directly impacting the inner wall of the water tank and thus preventing noise. Water in the water chamber rises slowly from bottom to top and is simultaneously discharged through the outlet. Due to the vent, even if the water level in the water chamber rises to contact the water-guiding structure, the vent connects the spaces formed by the opposite sides of the water-guiding structure and the inner wall of the water chamber, preventing air trapping and ensuring that the internal space of the water chamber remains open. This avoids deviations in the actual water intake caused by air trapping. Attached Figure Description

[0040] Please refer to Figures 1 to 3 The water tank 100 includes a tank body 1 and at least one water guiding structure 4. The tank body 1 has at least one water cavity, which has an inlet 1a and an outlet 1b spaced apart in the vertical direction. The outlet 1b is used to output water from the water cavity, and the inlet 1a is used to allow an external water source to enter. The water guiding structure 4 is disposed in the water cavity and extends in the vertical direction. At least part of the water guiding structure 4 is located below the inlet 1a. At least one vent hole 4a is formed on the water guiding structure 4, which is used to connect the opposite sides of the water guiding structure 4.

[0041] In this invention, water from an external source is introduced through inlet 1a and, after being guided by the water guiding structure 4, falls to the bottom of the water cavity. The water guiding structure 4 serves to guide and buffer the flow, preventing the water from directly impacting the inner wall of the water tank 100 and thus preventing noise generation. Water in the water cavity can rise slowly from bottom to top and is simultaneously discharged from outlet 1b. Due to the vent 4a, even if the water level in the water cavity rises to contact the water guiding structure 4, the vent 4a connects the spaces formed by the opposite sides of the water guiding structure 4 and the inner wall of the water cavity, preventing air trapping and ensuring that the internal space of the water cavity remains open. This avoids deviations in the actual water intake caused by air trapping in the water cavity.

[0042] It should be noted that the vent 4a can be designed by directly opening a hole on the rib plate corresponding to the water guiding structure 4, or a notch can be set on the side of the rib plate corresponding to the water guiding structure 4, which will naturally form a hole structure after fitting with the inner wall of the water tank 1.

[0043] This utility model does not limit the specific application scenario of the water tank 100. In some embodiments, there are two water chambers, which include a first water chamber 11 and a second water chamber 12 spaced apart in the horizontal direction. The inlet 1a of the first water chamber 11 is used to allow external hot water to enter, and the inlet 1a of the second water chamber 12 is used to allow external room temperature water to enter. The hot water output from the outlet 1b of the first water chamber 11 is used to mix with the room temperature water output from the outlet 1b of the second water chamber 12. A water guiding structure 4 is provided in the first water chamber 11 and / or the second water chamber 12. In this structure, hot water supplied by the municipal water supply system can flow into the first water chamber 11 from the corresponding inlet 1a, and room temperature water can flow into the second water chamber 12 from the corresponding inlet 1a, so that the water tank 100 can store water at different temperatures. The hot water in the first water chamber 11 is output from the corresponding outlet 1b, and the room temperature water in the second water chamber 12 is output from the corresponding outlet 1b. The hot and cold water can be mixed after being output, and can be mixed according to the usage requirements to obtain water at the required temperature. It can be seen that this utility model provides a new water tank 100, which can be directly adapted to the room temperature water and hot water supplied by the water supply system without the need for additional heating devices, and has strong applicability.

[0044] Specifically, the first water cavity 11 and the second water cavity 12 are integrated into a single housing 1. They can be distributed in a left-right direction or a front-back direction, and this invention does not impose any restrictions on this. The volumes of the first water cavity 11 and the second water cavity 12 can be the same or different.

[0045] It should be noted that the first water chamber 11 is connected to an external hot water source to store hot water flowing from the municipal water supply system. This means the external hot water source provides hot water to the municipal water supply system. Hot water typically refers to water with a temperature between 40 and 80 degrees Celsius. However, the specific temperature range may vary depending on the region, and the exact temperature of the hot water is not limited. The second water chamber 12 is connected to an external ambient temperature water source to store ambient temperature water flowing from the municipal water supply system. This means the external ambient temperature water source provides ambient temperature water to the municipal water supply system. Ambient temperature water is tap water, typically between 10 and 25 degrees Celsius. The specific temperature is affected by the season and environment; in winter, the ambient temperature water is lower, and in summer, it is higher. The exact temperature of the ambient temperature water is not limited.

[0046] This utility model does not limit the specific form of the water guiding structure 4. It can be integrated with the box body 1 or installed and fixed separately. When the box body 1 has a water cavity, one water guiding structure or multiple water guiding structures 4 can be set in the water cavity. The specific forms of multiple water guiding structures 4 can be different. When two water cavities are formed in the box body 1, the water guiding structure 4 can be set in only one water cavity or both water cavities can be set with water guiding structures 4. It should be understood that the water guiding structures in the first water cavity 11 and the second water cavity 12 can be the same or different.

[0047] In this embodiment, the inlets 1a in both water chambers are located on the upper wall of the housing 1, and the outlets 1b in both water chambers are located on the lower side of the housing 1.

[0048] Since the tank 1 is directly connected to the municipal water supply pipeline, in some embodiments, a one-way valve is installed at the inlet 1a to prevent water in the tank 1 from flowing back into the public water supply pipeline. By installing a one-way valve with a check function, backflow is prevented.

[0049] In some embodiments, please refer to Figures 2 to 3 The water guiding structure 4 includes a first water guiding section 41, at least a portion of which is inclined vertically. The first water guiding section 41 is located below the water inlet 1a. It should be understood that the first water guiding section 41 can be inclined vertically as a whole, forming an angle with the cavity wall. The first water guiding section 41 does not form a new closed space with the cavity wall of the water cavity, and the downward projection of the corresponding water inlet falls on the inclined section of the first water guiding section 41. The first water guiding section 41 contacts the three circumferential side walls of the corresponding water cavity, and the length and inclination of its inclined section are reasonably designed according to the position of the water inlet and the size of the water cavity. Specifically, an vent hole 4a is provided on the first water guiding section 41, so that the vent hole 4a connects the opposite sides of the first water guiding section 41. Even if the water level rises to the point of contacting the lower end of the first water guiding section 41, creating a space between the water surface, the first water guiding section 41, and the inner wall of the water cavity, the air can still be released through the vent hole 4a, preventing air entrapment.

[0050] It should be understood that the vent 4a should be located at the upper part of the first water guide 41, so as to avoid the vent 4a being blocked as the water level rises.

[0051] It should be noted that when both the first water cavity 11 and the second water cavity 12 are provided with water guiding structures 4, the water guiding structures 4 in the two water cavities can be the same or different. When the two water inlets 1a are close to each other in the horizontal direction, the two water guiding structures 4 can be symmetrically arranged.

[0052] The first water guiding section 41 includes two interconnected water guiding ribs. One water guiding rib extends vertically, while the other water guiding rib is inclined vertically. In the first water cavity 11, the inclined water guiding rib is located below the water inlet 1a, and the vertically extending water guiding rib extends to the side of the water inlet 1a. In the second water cavity 12, the vertically extending water guiding rib is located to the side of the water inlet 1a and connected to the upper wall of the second water cavity 12. The inclined water guiding rib extends to the side of the return water outlet 14.

[0053] Furthermore, the water guiding structure 4 also includes a second water guiding section 42, which is located above the water outlet. The second water guiding section 42 is at least partially inclined vertically and is at least partially below the lower end of the first water guiding section 41. The second water guiding section 42 can receive the water guided by the first water guiding section 41, thereby extending the water guiding path. At this time, multiple vent holes 4a are provided, which are respectively provided on the first water guiding section 41 and the second water guiding section 42. Accordingly, the arrangement of the vent holes 4a prevents air from being trapped between the second water guiding section 42 and the water surface and the wall of the water cavity.

[0054] It should be noted that the inclination directions of the second water guide 42 and the first water guide 41 can be the same or different. In this embodiment, the inclination directions of the first water guide 41 and the second water guide 42 are opposite, so that the water guide path can be long enough in a limited space, which can alleviate the water flow and prevent the water level in the water cavity from rising too fast.

[0055] It should be noted that the structures of the second water guide part 42 and the first water guide part 41 can be the same or different. In this embodiment, the second water guide part 42 is a rib that is inclined as a whole, and is fixed on the two side walls opposite to the water cavity, respectively, as is the first water guide part 41.

[0056] It should be understood that the vent 4a should be located at the upper part of the first water guide 41 and / or the second water guide 42, so as to avoid the vent 4a being blocked as the water level rises.

[0057] To monitor the water level inside the tank 1, a sensor 5 is installed in the first water chamber 11 and / or the second water chamber 12. The sensor 5 is used to detect the water level. Specifically, the lower side of the first water guide part 41 and the inner wall of the water chamber define a protective space for the sensor 5 to be placed. The vent 4a on the first water guide part 41 is positioned above the sensor 5 to allow the protective space to be open.

[0058] In consideration of resource recycling, in some embodiments, please refer to Figure 1The tank 1 is equipped with a return water inlet 14 that communicates with the second water chamber 12. The return water inlet 14 is located between the inlet 1a and the outlet 1b, and is used to connect with the recycled water source. That is, the recycled water source is introduced through the return water inlet 14, so that the recycled water source can enter the second water chamber 12 and mix with the room temperature water. It should be noted that a valve structure can be installed at the return water inlet 14 to control the opening and closing of the return water inlet 14, or the opening and closing control of the pump body at the external recycled water source can be directly controlled. That is, the water tank 100 has a mode of directly using the room temperature water provided by the municipality, a mode of mixing the municipal room temperature water and the recycled water, and a mode of closing the inlet 1a and using only the recycled water.

[0059] Considering that the housing 1 is equipped with a return water inlet 14 that communicates with the second water chamber 12, both the corresponding inlet 1a and the return water inlet 14 can receive water. Therefore, the lower end of the first water guide part 41 in the second water chamber 12 needs to extend to the horizontal side of the return water inlet 14. This allows the water flowing into the corresponding inlet 1a to flow down from the side of the return water inlet 14. At this time, the first water guide part 41 can also separate the inlet 1a and the return water inlet 14, preventing the water flow from impacting the two inlet positions and causing water to flow back from the return water inlet 14.

[0060] It should be understood that, in this embodiment, the water guiding path of the second water guiding part 42 in the second water cavity 12 should pass through the return water port 14, that is, the downward projection of the return water port 14 falls on the second water guiding part 42, so that the second water guiding part 42 can not only further guide the water guided by the first water guiding part 41, but also guide the water flowing into the return water port 14.

[0061] Due to the location of the return water inlet 14, two sensors 5 are installed in the second water cavity 12, located on opposite sides of the return water inlet 14 in the vertical direction. To protect the two sensors 5, the water guiding structure 4 also includes a third water guiding section 43. This third water guiding section 43 extends vertically and is located on the opposite side of the return water inlet 14 in the horizontal direction. The upper end of the third water guiding section 43 is connected to the first water guiding section 41. In this case, the third water guiding section 43 divides the first water guiding section 41 into a first mating section and a second mating section arranged sequentially in the horizontal direction. The second mating section is located above the return water inlet 14. The first mating section, the third water guiding section 43, and the cavity wall of the second water cavity 12 where the sensors 5 are located together form a space for the sensors 5, thereby simultaneously preventing the water flowing in from both the inlet and return water inlet 14 from impacting the sensors 5. Correspondingly, an vent hole 4a is provided in the first mating section to connect the space defined by the walls of the first mating section, the third water guide section 43, and the second water chamber 12; an vent hole 4a is provided in the second mating section to connect the space defined by the second mating section, the third water guide section, and the return water port 14. This ensures that the sections of the first water guide section 41 located on both sides of the third water guide section 43 can be connected through the vent hole 4a, preventing air from being trapped between any section of the first water guide section 41 in the horizontal direction and the water surface and the third water guide section 43.

[0062] Based on the above embodiments, the water tank 100 further includes a blocking part 45, which is located between the water guiding structure 4 and the water inlet 1a. The projection of the blocking part 45 on the water guiding structure 4 can cover the vent hole. The blocking part 45 ensures that when water enters through the water inlet 1a, even if there is splashing, the water flow can be blocked by the blocking part 45, preventing water from falling directly from the vent hole 4a and contacting the sensor 5, thereby ensuring the accuracy of the data detection by the sensor 5.

[0063] It should be noted that the size of the blocking part 45 is not limited, as long as it can correspond to the exhaust port.

[0064] Correspondingly, in the first water cavity 11, a blocking part 45 is provided above the vent hole 4a on both the first water guide section 41 and the second water guide section 42. In the second water cavity 12, among the two vent holes 4a on the first mating section and the second mating section, since the vent hole 4a on the second mating section corresponds to the return water port 14, and the shape of the first mating section extends vertically, the extension direction of the corresponding vent hole 4a is horizontal. Therefore, in the second water cavity 12, a blocking part 45 is provided only above the vent hole 4a on the second water guide section 42, and the vent hole 4a on the first water guide section 41 does not need to be provided with a blocking part 45.

[0065] Furthermore, the blocking part 45 is inclined vertically, so that the blocking part 45 can perform the functions of blocking and guiding.

[0066] If the water level in tank 1 increases too rapidly and sensor 5 fails to respond in time and control the inlet valve to close, a large amount of water in tank 100 will overflow, wetting other surrounding structural electrical components and causing a safety hazard. Therefore, in some embodiments, please refer to... Figure 3 The tank body 1 has an overflow port 13 that connects to the water chamber, and the overflow port 13 is located in the upper region of the water tank 100. The water guiding structure 4 also includes a fourth water guiding section 44, which extends vertically and is located between the overflow port 13 and the water inlet 1a. The fourth water guiding section 44 is provided with a vent hole 4a. The fourth water guiding section 44 prevents water from the water inlet 1a from splashing directly out of the overflow port 13. At the same time, in order to avoid air trapping in the fourth water guiding section 44 after the water level rises, a vent hole 4a is provided on the fourth water guiding section 44.

[0067] Correspondingly, in this embodiment, the housing 1 is provided with two overflow ports 13 that connect the first water chamber 11 and the second water chamber 12. The position of each overflow port 13 is lower than the corresponding water inlet, which is used to discharge foam, scum and other substances in the water chamber, and at the same time can prevent the water from flowing back into the tap water pipe after the chamber is filled.

[0068] This utility model does not limit the specific form of the fourth water guiding part 44. The fourth water guiding part 44 can be a structure that extends vertically, or it can be partially inclined vertically, or it can be inclined vertically as a whole.

[0069] Furthermore, a water guiding channel is defined between the fourth water guiding section 44 and the corresponding wall section, connecting to the overflow port 13 and open at the lower end. The cross-section of the water guiding channel gradually decreases from top to bottom. That is, the fourth water guiding section 44 can also guide overflow water and guide the flow. During the water intake process, even if the water splashes due to impact, it can still flow down along the surface of the fourth water guiding section 44.

[0070] In this embodiment, a vertically extending partition 3 is provided inside the tank 1, dividing the inner cavity of the tank 1 into a first water cavity 11 and a second water cavity 12. The lower end of the partition 3 is hollow to form a mixing cavity, and the outlet 1b is correspondingly formed at the lower end of the partition 3. The water tank 1 also includes a regulating valve 2, which is located inside the mixing cavity. The partition 3 serves to separate the inner cavity of the tank 1. A button for connecting the regulating valve 2 can be provided on the outside of the tank 1, allowing the operator to adjust the internal passage of the regulating valve 2 by controlling the button, thereby adjusting the connection between the regulating valve 2 and the two outlets 1b.

[0071] It should be noted that the partition 3 can be a separately installed plate structure, ensuring a sealed fit during installation, or it can be directly integrally formed with the box body 1. The thickness of the partition 3 can be uniform or uneven, and this utility model does not impose any restrictions on this.

[0072] Based on the above embodiment, the two water outlets 1b are staggered because if the two water outlets 1b are directly opposite each other, it will directly cause the two water chambers to be connected when the regulating valve 2 is opened.

[0073] It should be noted that the regulating valve 2 can be set as a solenoid valve and controlled by buttons via a circuit board assembly, or it can be connected to mechanical buttons for manual adjustment by the user.

[0074] In the technical solution of this utility model, the user sets the temperature by pressing a button connected to the regulating valve 2. The first water chamber 11 and the second water chamber 12 respectively receive the cold water and hot water inflow signals through the system. The water flows through the two inlets 1a and the water flow trajectory is as follows. Figure 3 As shown by the dashed line, during the water intake process, sensor 5 detects the water intake in real time. When the target water intake value is reached, the system closes the valve at the water inlet 1a and stops the water intake.

[0075] By employing a guide channel design between the inlet 1a and the sensor 5, the water flow into the water tank 100 from the outside does not directly impact the sensor 5, preventing false readings. Simultaneously, it reduces the buffering force of the water flow within the water tank 100 during water intake, resulting in lower noise. Furthermore, it enhances the structural strength of the water tank 100. An vent 4a is added to the water guiding structure 4 to prevent air trapping from causing discrepancies between the actual water intake and the sensor 5's reading. The blocking part 45 prevents water from the inlet 1a from flowing down through the vent 4a onto the sensor 5, ensuring the accuracy of the sensor 5's detection.

[0076] This utility model also proposes a cleaning machine, which includes a water tank 100. The specific structure of the water tank 100 is as described in the above embodiments. Since this cleaning machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0077] Understandably, cleaning machines can be used as household or commercial appliances. Their uses are varied; for example, they can be used as shower machines for bathing, or as cleaning equipment for appliances and furniture. The specific application is not limited. The dotted arrows in the accompanying diagram indicate the direction of water flow.

[0078] Specifically, the cleaning machine also includes a water outlet assembly. One end of the water outlet assembly is connected to the water outlet, and the other end is used to connect to the water user. The water outlet assembly may include water outlet components, including but not limited to: faucets, shower heads, etc. Of course, the water outlet assembly may also not include water outlet components. Users can configure suitable faucets, shower heads, etc. according to their own needs.

[0079] Furthermore, the water outlet assembly is connected to the regulating valve 2, specifically to discharge the water mixed from the two outlets to the water-using end.
