Description

Toilet, Toilet Control Methods and Electronic Equipment

[0001] This application claims priority to Chinese Patent Application No. 2024109360294, filed on July 12, 2024, entitled "Toilet, Toilet Control Method and Electronic Device", the contents of which are to be understood as incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, the field of bathroom technology, and more specifically, to a toilet, a toilet control method, and an electronic device. Background Technology

[0003] Current toilets typically use a water seal to prevent backflow of odors from the pipes. However, various situations can arise during toilet use. For example, in a flip-top toilet, the flip-top drain pipe may become stuck due to foreign objects and fail to reset. This results in a low water level in the drain pipe, which determines the water level on the toilet's water seal. Consequently, the water seal may be too low to achieve a proper water seal. Additionally, aging and leaks in the toilet's sealing connections can also prevent a proper water seal.

[0004] When faced with a toilet that fails to seal properly, resulting in backflow of odor, users are unable to determine the cause of the problem and therefore cannot address it effectively.

[0005] Summary of the Invention

[0029] This application provides a toilet. As shown in Figures 3-7, the toilet is a flip-top toilet, comprising a toilet body 1 and a sewage discharge module 2. The sewage discharge module 2 includes a sewage discharge box 21 fixed relative to the toilet body 1 and a sewage discharge pipe 22 at least partially located within the sewage discharge box 21. The sewage discharge pipe 22 is connected to the sewage discharge outlet of the toilet body 1 and is configured to rotate relative to the toilet body 1 around the central axis of the sewage discharge outlet between an initial position and a sewage discharge position. When rotated to the sewage discharge position, the sewage discharge pipe 22 discharges waste towards the discharge port of the sewage discharge box 21. The toilet also includes a control device, a water replenishment device, and a water level sensor 3. Both the water replenishment device and the water level sensor 3 are connected to the control device. The water level sensor 3 is configured to detect the water level on the toilet's surface. All devices requiring power, such as the water replenishment device, the water level sensor 3, and the control device, are connected to a power source, which can be a battery installed in the toilet or household mains power.

[0030] The control device is configured to: provide an alarm when the water level of the water cover meets a first condition, and control the water replenishment device to replenish water to the toilet body 1 when a second condition is met so that the water cover reaches the normal water level; wherein, the first condition is that the time t1 for the water cover to drop from the normal water level to the low water level when the toilet is not flushed does not exceed a first preset time T1, and the second condition is that the time t1 for the water cover to drop from the normal water level to the low water level when the toilet is not flushed exceeds the first preset time T1.

[0031] The normal water level is the water level of the toilet under normal conditions, set for odor prevention. The low water level is set to be lower than or equal to a preset water level below the normal water level. Figure 3 shows the toilet water level at the normal water level A in one embodiment, and Figure 4 shows the toilet water level at the low water level, which is lower than or equal to a preset water level B. The preset water level B has a preset water level difference with the normal water level A.

[0032] The technical solution provided in this application, when the toilet is not flushed, indicates that if the water level drop from the normal level to the low level within a time t1 that does not exceed a first preset time T1, the water level is dropping rapidly, thus indicating an abnormality in the toilet. This abnormality could be, for example, the drain pipe of a tilt-type toilet being blocked by a foreign object and unable to reset, resulting in a low water level, or other serious leaks in the toilet. When an abnormality is detected, a warning is given to the user, who can then inspect and repair the toilet. If the time t1 for the water level to drop from the normal level to the low level is greater than the first preset time T1, it indicates that the toilet is leaking slowly. This may be due to aging of the sealing connection, etc. (The sealing connection that causes slow leakage is usually the one located in the drain box that connects the drain pipe 22 to the drain outlet of the toilet body 1. Since leakage from other sealing connections may contaminate the bathroom, there is no need to detect slow leakage through water level detection). In this case, the user does not need to deal with the toilet or is in a hurry to deal with it. The toilet will automatically replenish water. In this way, when the water level drops without flushing the toilet, the toilet can automatically replenish water each time the time t1 for the water level to drop from the normal level to the low level exceeds the first preset time T1, in order to solve the problem of backflow caused by the low water level.

[0033] Therefore, the solution provided by the embodiments of this application can automatically determine the possible causes of low water level in the toilet when the water seal fails due to a low water level, and take different measures according to different situations. In the event of rapid leakage or other abnormalities (such as the drain pipe of a flip-top toilet being blocked by a foreign object and not flipping properly), the user is alerted and can be provided with targeted solutions to the toilet odor problem based on feedback. In the case of slow leakage, the control device can automatically replenish water to the toilet. Because this leakage is very slow, the entire device can be used for a long time without maintenance. During use, automatic water replenishment solves the odor problem caused by slow leakage due to the toilet's sealing connections and other factors, resulting in a low water level.

[0034] The solution provided in this application is suitable for flip-top toilets. Since it is common for the drain pipe of a flip-top toilet to be blocked by foreign objects and not flipped in place, when the control device gives a warning, the user can check whether the drain pipe of the toilet is not reset, thus quickly solving the problem of low water level.

[0035] In one embodiment, as shown in Figures 1 and 2, the control device may further be configured to: control the water replenishment device to replenish water to the toilet body when the information that the duration t2 of the water surface being at an excessively low water level is first obtained is greater than a second preset duration T2, so that the water surface reaches at least the normal water level. And after the water replenishment device replenishes water to the toilet body, the timer for the descent duration t1 is started.

[0036] The first acquisition of information that the duration t2 of the water surface at the low water level is greater than the second preset duration T2 means that the toilet has not previously experienced a situation where the duration t2 of the low water level is greater than the second preset duration T2. ​​When this situation occurs for the first time, the time it takes for the water surface to drop from the normal water level to the low water level is not detected. Therefore, in this case, the water replenishment device is controlled to replenish water to the toilet body. After the water level in the toilet body reaches the normal water level, the time t1 of the water surface dropping from the normal water level to the low water level can be started. Then, the abnormal situation of the water surface dropping to the low water level is judged based on the time t1.

[0037] In one embodiment, as shown in FIG1, the control device may further be configured as follows: after the timing of the descent duration t1 begins, if a flushing signal is obtained within a first preset duration T1 (i.e., t1≤12h, T1 is 12h in the embodiment of FIG1) during the descent duration t1, the water level of the water surface is detected before flushing. If the water level of the water surface is detected to be too low, it is determined that the water level of the water surface meets the first condition. If the water level of the water surface is not detected to be too low, the timing of the descent duration t1 is restarted. If no flushing signal is obtained within the first preset duration T1 (i.e., t1≤12h) during the descent duration t1, it is determined that the descent duration t1 is within the first preset duration T1 (i.e., t1≤12h) during the descent ... When t1 ≤ 12h, is the water level of the toilet surface detected as too low? If the water level of the toilet surface is detected as too low within the first preset time T1 of the descent time t1, then the water level of the toilet surface is determined to meet the first condition, the control device judges an abnormality, and an alarm is triggered. If the toilet is not flushed within the first preset time T1 (t1 > 12h) of the descent time t1, and the water level of the toilet surface is detected as too low, then the water level of the toilet surface is determined to meet the second condition, the water replenishment device is controlled to replenish water to the toilet body 1 so that the water surface reaches the normal water level, and the descent time t1 is reset. If the toilet is flushed within the first preset time T1 of the descent time t1, then the descent time t1 is reset.

[0038] In another embodiment, as shown in Figure 2, the control device can also be configured to: after starting to time the descent duration t1, determine whether the water level of the water cover is detected to be too low within a first preset duration T1 (i.e., t1≤12h, T1 is 12h in the embodiment of Figure 2); if the water level of the water cover is detected to be too low within the first preset duration T1, then determine whether the duration t2 of the water cover being at the too low water level is greater than a second preset duration T2 (T2 is 30s in the embodiment of Figure 2); if the duration t2 is greater than the second preset duration T2, then determine that the water cover is at the too low water level. If the first condition is met, the control device determines that there is an abnormality and issues an alarm. If the duration t2 is not greater than the second preset duration T2, it is determined that the drop in water level is due to flushing the toilet, and the drop duration t1 is reset. If the drop duration t1 exceeds the first preset duration T1 (t1 > 12h) and the toilet is not flushed while the water level is detected to be too low, the second condition is met. Water is added to the toilet body 1 to bring the water level to the normal level, and the drop duration t1 is reset. If the toilet is flushed while the drop duration t1 exceeds the first preset duration T1, the drop duration t1 is reset.

[0039] In one embodiment, as shown in Figures 3-7, the water level sensor 3 is installed on the sewage module 2 to detect the water level in the sewage pipe 22. Since the sewage pipe 22 is connected to the sewage outlet of the toilet body 1, the water level in the sewage pipe 22 is the water level of the toilet's water cover.

[0040] The water level sensor 3 can be a contact water level sensor. The water level sensor 3 is installed on the side wall of the sewage pipe 22. A hole can be made in the side wall of the sewage pipe 22 so that the water level sensor 3 can detect the water level by contacting the water in the sewage pipe 22 through the hole. In other embodiments, the water level sensor 3 can also be inserted into the water from the top opening of the sewage pipe 22 to detect the water level.

[0041] The water level sensor 3 can also be a non-contact water level sensor. The non-contact sensor can be a laser liquid level sensor, a capacitive liquid level sensor, or a photoelectric liquid level sensor, etc. The non-contact water level sensor can be installed on the outside of the side wall of the sewage pipe 22 or on the sewage box 21.

[0042] Figure 6 shows the water level sensor 3 installed on the outside of the side wall of the sewage pipe 22 of the sewage module 2, and Figure 7 shows the water level sensor 3 installed on the sewage box 21 of the sewage module 2.

[0043] As shown in Figure 7, the sewage box 21 includes a sewage box body 211 with an opening on one side and a sewage box cover 212 covering the opening on one side of the sewage box body 211. The sewage pipe 22 is installed into the sewage box 21 through the opening on one side of the sewage box body 211, and then the sewage box cover 212 is placed over the opening. A flipping power mechanism 23 is provided on the outside of the sewage box cover 212. This flipping power mechanism 23 is connected to the sewage pipe 22 through the sewage box cover 212 to drive the sewage pipe 22 to flip. In this example, the water level sensor 3 is a non-contact sensor and is located on the sewage box cover 212, but it can also be located on the sewage box body 211.

[0044] Since the sewage box 21 is located outside the sewage pipe 22, installing the water level sensor 3 on the sewage box 21 facilitates the exit of the connection wire of the water level sensor 3.

[0045] The control process when the toilet water cover fails is described below through two examples.

[0046] Referring to the embodiment in Figure 1, the water level sensor 3 detects the water level of the water surface. If the water surface is detected to be at an excessively low level (e.g., below 30mm), and the duration t2 of the excessively low water level is not greater than 30s (the second preset duration T2 is set to 30s), it is determined that the excessively low water level is due to toilet flushing, and the water surface can return to the normal water level within 30s. If the duration t2 of the water surface at the transitional water level is greater than 30s, it is determined that the excessively low water level is not due to toilet flushing, but rather that the toilet is experiencing abnormal conditions such as rapid or slow leakage. In this case, the water replenishment device is controlled to replenish water to the toilet body 1, so that the water surface reaches the normal water level, and the timer for the descent t1 is started to further determine the abnormal conditions of the toilet.

[0047] When the descent time t1 is less than or equal to 12 hours (i.e., t1 is within the first preset time T1, which is set to 12 hours), if the toilet is flushed, the water level of the water surface is detected before flushing. If the water level of the water surface is detected to be too low, it means that the water surface has dropped from the normal water level to the too low water level within the first preset time T1, and the water surface water level meets the first condition. Therefore, the control device determines that there is an abnormality and alarms. If the water surface is not detected to be too low, the descent time t1 is recalculated after flushing the toilet. That is, the descent time of the water surface from the normal water level to the too low water level is recalculated after flushing the toilet.

[0048] If the toilet is not flushed when the descent time t1 is less than or equal to 12 hours, it is determined whether the water level is too low when the descent time t1 is not greater than 12 hours. If the water level is too low when the descent time t1 is less than or equal to 12 hours, the water level meets the first condition, the control device determines that there is an abnormality and issues an alarm. If the toilet is not flushed when the descent time t1 exceeds the first preset time T1 and the water level is detected to be too low, the water level meets the second condition. The water replenishment device is controlled to replenish water to the toilet body 1 so that the water level reaches the normal water level, and the descent time t1 is reset. If the toilet is flushed when the descent time t1 exceeds the first preset time T1, the descent time t1 is reset.

[0049] Referring to the embodiment in Figure 2, the water level sensor 3 detects the water level of the water surface. If the water surface is detected to be at an excessively low level (e.g., below 30mm), and the duration t2 of the excessively low water level is no greater than 30s (the second preset duration T2 is set to 30s), it is determined that the excessively low water level is due to toilet flushing, and the water surface can return to the normal water level within 30s. If the duration t2 of the water surface at the transitional water level is greater than 30s, it is determined that the excessively low water level is not due to toilet flushing, but rather that the toilet is experiencing abnormal conditions such as rapid or slow leakage. In this case, the water replenishment device is controlled to replenish water to the toilet body 1, so that the water surface reaches the normal water level, and the timer for the descent t1 is started to further determine the abnormal conditions of the toilet.

[0050] When the descent time t1 is less than or equal to 12 hours (i.e., t1 is within the first preset time T1, which is set to 12 hours), if the water surface is detected to be at an excessively low level, it is necessary to determine whether the duration of the water surface being at an excessively low level is greater than 30 seconds (i.e., whether the duration of the water surface being at an excessively low level t2 is greater than the second preset time T2) in order to determine whether the water surface being at an excessively low level is due to flushing the toilet. If the duration t2 is greater than 30 seconds, it is determined that the water surface level meets the first condition, the control device determines that there is an abnormality, and an alarm is triggered. If the duration t2 is not greater than 30 seconds, it is determined that the water surface being at an excessively low level is due to flushing the toilet, and the descent time t1 is reset.

[0051] If the toilet is not flushed within a descent time t1 that exceeds the first preset time T1 and the water level is detected to be too low, then the water level meets the second condition. The water replenishment device is then controlled to replenish water to the toilet body 1 so that the water level reaches the normal water level, and the descent time t1 is reset. If the toilet is flushed within a descent time t1 that exceeds the first preset time T1, then the descent time t1 is reset.

[0052] It should be noted that the T1 of 12h, T2 of 30s, and the low water level of 30mm are all parameters set for the toilet in this application. Depending on different situations or needs, T1, T2, and the low water level can be set to other values, which are not restricted here.

[0053] An embodiment of this application also provides a method for controlling a toilet. The toilet includes a toilet body and a sewage discharge module. The sewage discharge module includes a sewage discharge box fixed relative to the toilet body and a sewage discharge pipe at least partially located within the sewage discharge box. The sewage discharge pipe is connected to the sewage discharge outlet of the toilet body, and the sewage discharge pipe is configured to rotate relative to the toilet body around the central axis of the sewage discharge outlet between an initial position and a sewage discharge position. In the sewage discharge position, the sewage discharge pipe discharges waste toward the discharge port of the sewage discharge box. The control method includes:

[0054] Get the water level at the toilet bowl's water cover;

[0055] The time t1 for the water cover to drop from the normal water level to the excessively low water level is timed;

[0056] An alarm is triggered when the water level on the water surface meets the first condition; when the water level on the water surface meets the second condition, the water replenishment device is controlled to replenish water to the toilet body so that the water surface reaches the normal water level.

[0057] The first condition is that the time t1 for the water level to drop from the normal water level to the low water level when the toilet is not flushed does not exceed the first preset time T1. The second condition is that the time t1 for the water level to drop from the normal water level to the low water level when the toilet is not flushed exceeds the first preset time T1.

[0058] In one embodiment, before timing the time t1 of the water cover descending from the normal water level to the excessively low water level, the method further includes;

[0059] When the information is obtained that the duration t2 of the water surface being at an excessively low water level is greater than the second preset duration T2, the water replenishment device is controlled to replenish water to the toilet body so that the water surface reaches the normal water level.

[0060] In one embodiment, after timing the time t1 for the water surface to drop from the normal water level to the excessively low water level, the method may further include:

[0061] If the signal to flush the toilet is obtained within the first preset time T1 during the descent time t1, the water level of the water cover is detected before flushing. If the water level of the water cover is detected to be too low, it is determined that the water level of the water cover meets the first condition. If the water level of the water cover is not detected to be too low, the descent time is reset.

[0062] If no flushing signal is obtained within the first preset time T1 during the descent time t1, it is determined whether the water level of the water cover is detected to be too low within the first preset time T1 during the descent time t1. If the water level of the water cover is detected to be too low, it is determined that the water level of the water cover meets the first condition; if the water level of the water cover is not detected to be too low, it is determined that the water level of the water cover meets the second condition.

[0063] In one embodiment, after timing the time t1 for the water surface to drop from the normal water level to the excessively low water level, the method may further include:

[0064] Determine whether the water level on the water cover is detected to be too low within the first preset time T1 when the descent time t1 is descent.

[0065] If the water level of the water cover is detected to be too low, it is determined whether the duration t2 of the water cover being at the low water level is greater than the second preset duration T2. ​​If the duration t2 is greater than the second preset duration, it is determined that the water level of the water cover meets the first condition. If the duration t2 is not greater than the second preset duration T2, the timer for the descent duration t1 is reset.

[0066] If no excessively low water level is detected on the water cover, then the water cover level is determined to meet the second condition.
