Description

Technical field

[0001] The present invention relates to a water tank for smart toilets. State of the art

[0002] Water tanks for smart toilets feature an anti-siphon function. This is achieved by typically building the tanks taller, increasing the vertical distance between the water inlet and the liquid level inside the tank. This prevents backflow of liquid through the inlet. However, the trend in smart toilets is towards lighter and smaller designs, leaving insufficient vertical space for the water tank's installation. Therefore, taller tanks are no longer suitable for use in smart toilets. Subject matter of the invention

[0003] The invention provides a water tank for smart toilets with an anti-siphon function and low height, thereby overcoming the disadvantages of the prior art. The proposed technical concept for solving the problems posed is as follows: a water tank for smart toilets comprising a lower bowl and an upper cover, wherein a water outlet is provided on the lower bowl, wherein a water spray chamber and a water collection chamber are arranged on the upper surface of the upper cover, wherein the water spray chamber and the water collection chamber are arranged adjacent to each other, wherein a water spray opening is provided on the side wall of the water spray chamber, and wherein a water outlet is provided on an intermediate side wall separating the water spray chamber from the water collection chamber, wherein the water spray opening and the water outlet are arranged opposite each other.so that the water can be sprayed from the water spray opening to the water outlet, wherein a first water drain opening is provided on the lower part of the water spray chamber, wherein the lower part of the water collection chamber is connected to the lower shell, wherein a second water drain opening is provided on the upper side of the lower shell, and wherein the water outlet is arranged higher than the second water drain opening.

[0004] In an advantageous embodiment, a water connection nozzle is inserted into the water spray opening.

[0005] In an advantageous embodiment, a water overflow channel is provided on the side of the lower shell, with the first water drain opening and the second water drain opening opening into the water overflow channel.

[0006] In an advantageous embodiment, the length of the lower shell is greater than its height.

[0007] In an advantageous embodiment, a level float for measuring the level of the fill in the lower bowl and an electromagnetic valve for opening and closing the water connection nozzle are also provided, wherein the level float and the electromagnetic valve are in signal communication with a main control board.

[0008] In an advantageous embodiment, a water pump is further included, wherein the lower shell has a pump inlet and a pump outlet associated with the water pump, the pump inlet being connected to the water outlet, and the water pump being in signal communication with the main control board.

[0009] In an advantageous embodiment, the bottom of the lower bowl is provided with a water drainage opening which is closed by a sealing plug.

[0010] In an advantageous embodiment, the upper cover is connected to the lower shell by a snap closure, with a sealing strip provided between the two.

[0011] In an advantageous embodiment, the upper cover has an inlet for descaling agents.

[0012] In an advantageous embodiment, an inlet for descaling circulating water is provided on the upper cover.

[0013] Compared to the state of the art, the present technical concept offers the following advantages: 1. The water spray opening and the water outlet are located on two opposite side walls, separated by a partition. This ensures that water in the tank cannot flow back into the spray opening. Furthermore, the water outlet is positioned higher than the second water outlet, so that with continuous water intake, the water level inside the tank can only reach the second outlet and not the water outlet. This prevents siphon backflow. Additionally, a spray chamber and a collection chamber, each with a spray opening and outlet, are provided to separate the water intake and outlet paths. Consequently, the structure of the spray chamber and collection chamber is not only simple but also occupies minimal vertical space.This ensures a compact overall height for the water tank and allows for a slim design suitable for smart toilets. 2. The water overflow channel can channel water overflowing from the lower bowl, as well as water entering the spray chamber from the spray nozzle during the spray function, out of the water tank together, resulting in a simple and compact design. 3. When the liquid level in the lower bowl falls below the preset level, the float sends a signal to refill the water. Upon receiving this signal, the main control board sends a command to the electromagnetic valve to open the water inlet. When the liquid level reaches the preset level, the float sends a signal to stop the water supply.After receiving the signal, the main control board sends a command to the electromagnetic valve to close the water inlet, thus ensuring precise and automatic filling of the water tank. 4. Removing the sealing plug allows the water to drain from the water tank through the drain opening, facilitating cleaning. Character description

[0014] The invention will now be explained in more detail with reference to exemplary embodiments in connection with the attached drawing. Figure 1 shows a three-dimensional exploded view of the water tank for smart toilets. Figure 2 shows a partial cutaway view of the water tank for smart toilets according to Figure 1 from above. Figure 3 shows a cutaway view of the water tank for smart toilets according to Figure 1 from the front. Specific example of implementation

[0015] As in the Figures 1 to 3As shown, the water tank for smart toilets comprises a lower bowl 10 and an upper cover 20, the lower bowl being used for filling with water, having a water outlet 11 on the lower bowl 10, and the upper cover serving to cover the upper opening of the lower bowl. A water splash chamber 21 and a water collection chamber 22 are provided on the top of the upper cover 20, the splash chamber and the collection chamber being arranged adjacent to each other. A water splash opening 23 is provided on the side wall of the splash chamber 21. A water outlet 24 is provided on an intermediate side wall separating the splash chamber 21 from the collection chamber 22, with the splash opening 23 and the water outlet 24 being arranged opposite each other so that water can be splashed from the splash opening 23 to the water outlet 24.A first water drain opening 25 is provided on the lower part of the water spray chamber 21. The lower part of the water collection chamber 22 is connected to the lower tray 10. A second water drain opening 12 is provided on the upper side of the lower tray 10, with the water outlet 24 being positioned higher than the second water drain opening 12.

[0016] When the water tank is filled, the water is sprayed from the water spray opening 23 to the water outlet 24, enters the water collection chamber 22, and falls into the lower tray 10. Water sprayed from the water spray opening 23 onto the opposite side wall of the water spray chamber 21 flows out through the first water drain opening 25. If a malfunction occurs that prevents the water supply from being shut off, the water level in the lower tray 10 rises slightly to the level of the second water drain opening 12 and flows out of it. If a siphon effect occurs, the liquid level in the lower tray 10 remains below the water outlet 24. Furthermore, due to the second water drain opening 12, the water cannot flow back to the water outlet 24.Since the water spray opening 23 and the water outlet 24 are each located on two opposite side walls, the water, even if it flows back from the water outlet 24, can only enter the water spray chamber 21 and flow out through the first water drain opening 25 without entering the water spray opening 23.

[0017] Advantageously, a water connection fitting 26 is inserted into the water spray opening 23, whereby the water connection fitting 26 facilitates the water connection of the water tank. Spraying the water from the water spray opening 23 has the same effect as spraying it from the water connection fitting 26.

[0018] Advantageously, a water overflow channel 13 is provided on the side of the lower bowl 10, with the first water drain opening 25 and the second water drain opening 12 opening into the water overflow channel 13. The water overflow channel 13 can be connected to the toilet bowl.

[0019] The length of the lower bowl is advantageously greater than its height. The figures clearly show that the water tank has an overall flat design.

[0020] Advantageously, a level float 30 for measuring the fill level in the lower tray 10 and an electromagnetic valve 40 for opening and closing the water connection nozzle 26 (or the water spray opening 23) are provided, wherein the level float 30 and the electromagnetic valve 40 are in signal communication with a main control board (not shown in the figures). Preferably, a water pump 50 is also provided, wherein the lower tray 10 has a pump inlet 14 and a pump outlet 15, which are assigned to the water pump 50, the pump inlet 14 being connected to the water outlet 11, and wherein the water pump 50 is in signal communication with the main control board. During operation, the main control board sends a signal to the water pump 50, which then starts and draws in water.When the water level in the lower tray 10 drops to a preset level, the level sensor 30 sends a signal to the main control board. The main control board sends a command to the electromagnetic valve 40 to open the water inlet 26 to begin filling with water. When the water level in the lower tray 10 rises to a preset level, the level sensor 30 sends a signal to the main control board. The main control board sends a command to the electromagnetic valve 40 to close the water inlet 26.

[0021] Advantageously, the bottom of the lower tray 10 is provided with a water drainage opening, which is sealed by a sealing plug 16. If the water collected in the lower tray needs to be drained when cleaning the water tank, the sealing plug 16 can be opened manually.

[0022] Advantageously, the upper cover 20 is connected to the lower shell 10 by a snap closure, with a sealing strip 60 provided between the two.

[0023] Advantageously, the upper cover 20 has an inlet 27 for descaling agent. Furthermore, an inlet 28 for circulating descaling water is advantageously provided on the upper cover. During descaling, descaling agent can be added through inlet 27. The descaling water can then flow back into the water tank through inlet 28, allowing for reuse.

[0024] The foregoing descriptions merely highlight advantageous embodiments of the invention, without limiting its scope. All equivalent modifications or embodiments within the scope of the present invention and the description herein are also covered by the scope of protection of the present invention.
