Description

Kitchen and bathroom basin drainage system and control method for kitchen and bathroom basin drainage system

technical field

The present invention relates to a drainage system, and more specifically, to a drainage system for a kitchen and bathroom basin for smart homes and a control method for the drainage system for the kitchen and bathroom basin.

Background technique

The sink is an integral part of home life, but clogging of the kitchen and bathroom sink drainage system is a common problem. Especially the basin used in the kitchen is frequently used to clean dishes, fruits and vegetables, and it is inevitable that food waste and oil will accumulate in the drainage system of the basin. And even the kitchen and bathroom basin drainage system used in the bathroom can be blocked by hair and clothing wool. Although the current kitchen basin is provided with a garbage filter bowl in the drain outlet, oil stains and fine food residues will still enter the drainage system through the garbage filter bowl during cleaning. For example, in the process of cleaning the bowls and chopsticks after eating, the remaining oil soup and food residues will be poured into the water basin, and the oil stains that have not been washed away by the water will adhere to the wall of the drainage pipe, and the attachments will gradually fade away due to their stickiness. More and more oil and food residues accumulate, eventually leading to blockage of the kitchen sink drainage system. If blockage occurs, it is necessary to use supplies such as pipe dredging agent to dredge it through chemical action; The time required is usually longer, and in some cases of severe blockage, the effect may not be achieved within a reasonable time, and the residents have to give up halfway and switch to other methods. Or use physical methods to unclog, that is, dismantle the pipes of the drainage system to directly clean up the blockages. For irregular or long pipes, or when the installation position of the pipes is restricted, special tools are required. Dredging, time-consuming and labor-intensive and to endure the unpleasant smell, if you ask a professional door-to-door service will bear a lot of money.

With the advancement of science and technology and the development of society, especially under the premise that computer technology, communication technology and control technology are vigorously developed and can solve practical problems more and more widely and effectively, smart cities and smart cities with higher intelligence have emerged. A more humane smart home enables many difficult problems that existed in home life to be solved through intelligent design.

Contents of the invention

The purpose of the present invention is to solve the problems existing in the prior art, and propose an intelligently designed kitchen and bathroom basin drainage system, which can predict in advance the blockage of the kitchen and bathroom basin drainage system that has just started or will occur, thereby It avoids that the residents have to wait until the blocked sewage overflows to the drain of the water basin or the slow water discharge in the water basin has been clearly observed before realizing the occurrence of the blockage, so that they can timely dispose of the blockage when the blockage is not serious. Therefore, it is relatively easy to solve the clogging of the drainage system of the kitchen and toilet basin. According to the structure of the kitchen and bathroom basin drainage system, the places where blockages are likely to occur are usually located at the anti-odor bend and the laterally inclined drainage branch pipes, while the vertically extending downpipe section below the drain is less likely to be blocked first. Therefore, the idea of the present invention is to monitor the clogging of the drainage system of the kitchen and bathroom basin by real-time monitoring the drop rate of the liquid level in the downpipe above the anti-odor bend.

Further preferably, the cut-off valve is an electric cut-off valve communicated with the main controller, and the main controller can be controlled by residents.

In addition, the present invention also relates to a method for controlling the drainage system of the kitchen and bathroom basin for smart homes, and the method for controlling the drainage system of the kitchen and bathroom basin includes:

Step S1: Provide a kitchen and bathroom basin drainage system, the kitchen and bathroom basin drainage system includes a basin body with a drain outlet, a downpipe extending from the drain outlet with an odor-proof bend, and connecting the lower The water pipe and the drainage branch pipe of the drainage main pipe, a liquid level sensor is arranged above the odor-proof bend in the downpipe, and at least one vibrator is arranged on the drainage branch pipe, and the flow rate is also set on the drainage branch pipe. sensor;

Step S2: providing a main controller with an alarm function, the liquid level sensor, the flow rate sensor and the at least one vibrator are respectively communicated with the main controller, and the main controller is set so that all The main controller stores the critical time T ₀ , when the liquid level position of the liquid in the downpipe reaches the highest detected liquid level of the liquid level sensor until it falls to the lowest detected liquid level of the liquid level sensor. and the critical flow velocity V ₀ of the liquid in the drainage branch pipe, and the main controller can obtain the liquid level position of the liquid in the downpipe in real time from reaching the highest detected liquid level of the liquid level sensor until it drops The actual time T until the lowest detected liquid level of the liquid level sensor, and the instantaneous flow velocity V of the liquid in the branch discharge pipe, if V is less than V ₀ and T is greater than T ₀ , the main controller The at least one vibrator is turned on for a time t, thereby applying vibration to the exhaust branch pipe, and then if the situation that V is less than V ₀ and T is greater than T ₀ occurs twice within a certain period of time, the main control alarm.

Further, the branch drainage pipe is connected to the main drainage pipe through a shut-off valve, and if the main controller alarms, the resident can close the shut-off valve and perform a corresponding dredging operation on the drainage system of the kitchen and bathroom basin.

Furthermore, the branch drainage pipe includes an inner layer made of metal material and an outer layer made of heat insulating material capable of electric heating, and the resident can heat the branch drainage pipe by manipulating the main controller.

Furthermore, the downpipe includes an inner layer made of metal material capable of electric heating and an outer layer made of heat insulating material, and the resident can heat the downpipe by manipulating the main controller.

Preferably, the shut-off valve is an electric shut-off valve communicated with the main controller, and the resident can close the shut-off valve through the main controller and perform a corresponding dredging operation on the drainage system of the kitchen and bathroom basin.

The advantage of the present invention is that: in the process of discharging the used water through the kitchen and bathroom basin drainage system, the liquid flow rate in the drainage branch pipe combined with the drop rate of the liquid level at the position close to the anti-odor bend in the vertical section of the downpipe can It is a good illustration of the unobstructed condition of the kitchen and bathroom basin drainage system. Since there is always a water seal in the deodorant bend, it is easier to change the liquid level near the deodorant bend even if the water consumption is not too high, especially after each water use In the process of the drainage water level falling, the speed of the water level falling in such a process is directly affected by the unobstructed degree of the drainage system. According to the current common practice, the residents can only observe the smoothness of the drainage through the water outlet of the basin, and this usually occurs when the drainage system has been severely blocked so that normal use is affected. When the above situation occurs, most residents will Choose to use a pipe dredging agent and pour a large amount of high-temperature water to dredge. Such steps often need to be repeated. However, because the dredging agent and hot water cannot be kept in the pipeline for a long time, a considerable part of the dredging agent has not fully functioned. Discharge, causing a lot of waste and seriously affecting the effect of dredging. The present invention monitors in real time the drop rate of the liquid level of the sewer pipe at the position above the odor-repellent bend, so that residents can predict the clogging of the kitchen and bathroom basin drainage system in advance and take measures in advance, which is not too serious in the case of clogging circumstances are particularly favorable. For example, through the vibrating action of the vibrator installed on the pipeline, the blockage attached to the inner wall of the pipeline can be loosened or the adhesion force can be reduced, so that the blockage can be washed away by the impulse of the water flow in subsequent use, thereby realizing the maintenance of the pipeline. The purpose of dredging; in addition, in the case of a blockage alarm in the main controller, the household can selectively close the shut-off valve and add an appropriate amount of pipe dredging agent and water to the drainage system when no water is needed. After an appropriate time, the resident can open the shut-off valve and continue to monitor the effect of pipeline dredging in real time during subsequent use. According to a preferred embodiment of the present invention, the drainage branch pipe and/or the downpipe comprise an inner layer made of a metal material and an outer layer made of a heat-insulating material capable of being electrically heated, so that if an alarm occurs, the occupant can close the After the valve, the drainage branch pipe and/or the downpipe are energized and heated, so as to avoid pouring a large amount of hot water into the drainage system of the kitchen and bathroom basin and keep the high temperature in the pipe during the dredging process. Since high temperature has a good effect on melting oil stains, it is possible to achieve the purpose of dredging only by melting oil stains with high-temperature water kept in the pipeline even without using a dredging agent. In addition, setting the drainage branch pipe and/or the downpipe to have a heating function can also prevent the pipes from freezing when the room temperature is low. The inner layer that can be heated is covered by the outer layer made of thermal insulation material, which can not only achieve the purpose of safety, but also reduce energy consumption through insulation. According to a further preferred embodiment of the present invention, the main controller has an interactive display screen for the residents, so that the residents can know the change of the liquid level in real time; alternatively, the main controller can display the temperature in the pipeline, for example, by means of A temperature sensor arranged in the pipeline.

Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Fig. 1 is a kitchen and bathroom basin drainage system for smart homes according to an embodiment of the present invention. device (not shown in the drawing). Wherein, the water basin body 1 has a water outlet 2 at the bottom, and a garbage filter bowl (not shown) for filtering larger food residues and cleaning residues is arranged in the water outlet 2 . The first end of the downpipe 4 is, for example, connected to the downspout 2 of the water basin body through a bowl 3; in addition, the downpipe 4 includes a vertical section extending vertically downward from the downspout and a vertical section positioned at the upright section. The downstream odor-proof bend 5 prevents the odor gas in the main exhaust pipe from entering and overflowing from the water basin through the water seal formed therein. The initial end of the branch drainage pipe 7 is connected to the second end of the downpipe 4 , and the terminal end of the branch drainage pipe is connected to the main drainage pipe 8 through a shut-off valve 9 . At least one vibrator 10 is arranged on the drainage branch pipe, and according to the size of the drainage branch pipe and the specification of the used vibrator, one or two vibrators can be selected to be set on the drainage branch pipe, and the vibrator is for example an ultrasonic vibrator; according to the present invention In an alternative embodiment, an additional vibrator may be provided on the downpipe, preferably downstream of the odor trap. The vibrator is communicated with the main controller, so that it can be turned on by the main controller under certain conditions; or can be turned on by the user's manipulation of the main controller. In addition, a flow velocity sensor 11 communicated with the main controller is also provided in the branch drainage pipe to monitor the flow velocity V of the liquid in the branch drainage pipe in real time. The downpipe 4 is provided with a liquid level sensor 6 above the odor-proof bend 5, and the liquid level sensor 6 communicates with the main controller (not shown) to monitor the liquid level change at this position in real time. At the same time, the main controller The controller obtains the time of liquid level change through its timing module. For example, in the process of dropping the liquid level after each time the water is used, the main controller obtains the liquid level position of the liquid in the downpipe 4 from reaching the highest detection liquid level of the liquid level sensor until falling to the level of the liquid level sensor. The actual time T until the lowest detected liquid level. In addition, the storage module of the main controller stores the liquid level position of the liquid in the downpipe from reaching the highest detected liquid level of the liquid level sensor until falling to the lowest detected liquid level of the liquid level sensor. The critical time T ₀ until the position, and the critical flow rate V ₀ of the liquid in the drainage branch pipe, if V is less than V ₀ and T is greater than T ₀ , the main controller will start the vibrator for a time t. Then, if V is less than V ₀ and T is greater than T ₀ twice within a certain period of time, the main controller will give an alarm. If an alarm occurs, the resident can selectively close the shut-off valve 9 and perform corresponding dredging operations in the time when water is not needed, for example, adding an appropriate amount of pipeline dredging agent and water to the drainage system. After an appropriate time, the resident can open the shut-off valve 9 and continue to monitor the effect of pipeline dredging in real time during subsequent use. It should be noted that the liquid level sensor is preferably located at the lower part of the vertical section of the downpipe that extends downward from the water outlet of the basin, but the lowest liquid level that the liquid level sensor can detect should be located in the odor-proof bend of the downpipe The water seal is above the highest liquid level in a static or balanced state, thereby ensuring the accuracy of the measurement of the time when the liquid level drops. In addition, the setting of the position of the liquid level sensor needs to consider the change of the liquid level of the water seal in the odor trap, for example, due to the influence of the air pressure in the exhaust branch pipe through the exhaust main pipe.

In a preferred embodiment of the present invention, the branch drain pipe 7 and/or the downpipe 4 comprise an electrically heatable inner layer made of metal material and an outer layer made of heat insulating material. Therefore, if an alarm occurs, the occupant can energize and heat the drain branch pipe 7 and/or the downpipe 4 after closing the shut-off valve 9, thereby avoiding pouring a large amount of hot water into the drainage system of the kitchen and bathroom basin and during the dredging process. Always maintain a high temperature in the pipe. Since high temperature has a good effect on melting oil stains, it is possible to achieve the purpose of dredging only by melting oil stains with high-temperature water kept in the pipeline even without using a dredging agent. In addition, setting the drainage branch pipe 7 and/or the downwater pipe 4 to have a heating function can also prevent the pipes from freezing when the room temperature is low. In addition, the user can turn on the vibrator for a certain period of time through the main controller while performing the above operations according to needs, so as to assist the dredging effect.

Preferably, the heating temperature of the inner layer of the drainage branch pipe 7 or the inner layer of the downpipe 4 can be controlled by the main controller, so that the residents can control the temperature of the drainage branch pipe 7 and/or the downwater pipe 4 through the main controller.

Since the main drainage pipe is usually located in a corner that is not easily accessible in the kitchen, preferably, the shut-off valve 9 is an electric shut-off valve communicated with the main controller, so that in the event of an alarm, the resident can control the shut-off valve 9 through the main controller , thereby preventing the flow of liquid from the drain branch to the drain main.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
