The traditional toilet adopts an upper-exhaust mechanical ventilation mode, and introduces outdoor fresh air through a door gap and the like by utilizing indoor negative pressure, so as to supplement air for the toilet. The ventilation air-conditioning facility with the upper air exhaust, the upper air supply and the upper air return easily causes the mutual smell mixing of the air supply and the air exhaust, thereby reducing the ventilation effect.

For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.

In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
In the specific technical field of toilet ventilation, the conventional ventilation and air conditioning facilities with upper air exhaust, upper air supply and upper air return mainly have the following problems: firstly, pollutants generated by a toilet bowl and a urinal at the lower part of a toilet can be diffused indoors and then discharged from an air outlet at the upper part of the toilet in an air flow organization mode of upward air exhaust, so that the indoor air quality is poor; secondly, the air is supplemented to the toilet from the public area, so that the odor tainting is easily caused. According to the analysis of the air volume balance principle, the actual air volume cannot meet the design requirement due to the fact that air is supplemented through the permeation of the gaps of the doors and windows only under the action of pressure difference; thirdly, according to the requirements of GB 50736-2012 'design Specification for heating, ventilating and air conditioning of civil buildings', the number of times of ventilation of a public washroom is regulated to be 5-10 times/h. The air conditioner load of a room can be increased due to the large designed air exhaust amount, and the air flow organization of an air conditioning system can be seriously influenced when the upper air exhaust opening is close to the upper air supply opening of the air conditioner due to the limited toilet area, so that the energy consumption is wasted; and fourthly, the space of the toilet is limited, and the exhaust system and the independent air conditioning system are too redundant to occupy the installation space at the upper part.
In the related field, a common toilet lower exhaust system is provided with an exhaust duct indoors, a lining exhaust pipe is arranged behind each squatting position, and an exhaust outlet is arranged at the lower part of each air pipe, so that polluted air generated by a toilet bowl is exhausted.
Although the air exhaust method avoids the problems of 'taint of odor' and the like caused by upward air exhaust type upward delivery and upward return, the air exhaust method realizes air exchange by forming a relatively low-pressure environment in a toilet by an exhaust fan, and has poor air supplement capability, thereby causing poor ventilation effect.
In order to solve the above problems, the present embodiment provides a ventilation system, and when the ventilation system of the present invention is used to exhaust air from a toilet, polluted air in the toilet enters an exhaust duct through an exhaust outlet, and then flows through a nozzle in a connection pipe box to generate a high-speed air flow, and the high-speed air flow is sprayed to an exhaust outlet duct and exhausted, so that a relatively low-pressure environment is formed in the connection pipe box, and thus outdoor fresh air is introduced into the connection pipe box, and the fresh air is cooled/heated by a coil pipe and then is sent into the toilet through an air supply outlet pipe, so that the air supply capacity of the ventilation system to the toilet is improved on the basis of ensuring good lower exhaust air flow organization of the toilet, and the ventilation effect of the ventilation system is further improved.
Fig. 1 shows a schematic structural view of the exhaust system of the present embodiment. Specifically, the exhaust system is attached to the toilet 17 and includes an exhaust pipeline, an air supply pipeline and a pipe connection box 11. Polluted air in the toilet 17 is discharged through an exhaust pipeline, and outdoor fresh air is sent into the toilet 17 through an air supply pipeline, so that air exchange of the air in the toilet 17 is completed; the exhaust pipeline and the air supply pipeline are intersected at the joint pipe box 11, and a low-pressure environment relative to the outdoor environment can be formed in the joint pipe box 11 when the exhaust pipeline exhausts air, so that outdoor fresh air is introduced into the joint pipe box 11 and finally into the toilet 17 depending on the pressure difference effect.
The exhaust duct includes an exhaust inlet duct and an exhaust outlet duct, and an exhaust outlet of the exhaust inlet duct is disposed in a bottom space of the toilet 17, for example, near the toilet 19, or disposed inside the toilet 19, specifically, in a cavity of the toilet 19 for accommodating dirt. The air supply pipeline comprises an air supply pipeline which comprises an air supply inlet pipeline and an air supply outlet pipeline, and an air supply outlet 16 of the air supply outlet pipeline is arranged in the top space of the toilet 17.
The pipe receiving box 11 has a cavity, and the air exhaust inlet pipeline, the air exhaust outlet pipeline, the air supply inlet pipeline and the air supply outlet pipeline are connected into the pipe receiving box 11, specifically, are communicated with the cavity of the pipe receiving box 11. The air exhaust inlet pipeline and the air exhaust outlet pipeline are provided with an air exhaust air path in the cavity, and the air supply inlet pipeline and the air supply outlet pipeline are provided with an air supply air path in the cavity.
Specifically, the exhaust air path is formed between the port of the exhaust air inlet duct located in the header 11 and the port of the exhaust air outlet duct located in the header 11, and the supply air path is formed between the port of the supply air inlet duct located in the header 11 and the port of the supply air outlet duct located in the header 11. The port of the exhaust air inlet duct at the junction box 11 and the port of the exhaust air outlet duct at the junction box 11 may be disposed above the port of the supply air inlet duct at the junction box 11 and the port of the supply air outlet duct at the junction box 11, so that the exhaust air path is formed above the supply air path.
Also arranged in the header tank 11 is a nozzle 8, which nozzle 8 is intended to create a low-pressure environment in the header tank 11, which is capable of introducing fresh outdoor air into the toilet 17. Specifically, the nozzles 8 may be disposed at the end of the exhaust air inlet duct located at the header box 11, while the spouts of the nozzles 8 may be disposed toward the exhaust air outlet duct. Therefore, when the exhaust duct is formed by injecting the polluted air from the exhaust inlet duct to the exhaust outlet duct by the nozzle of the nozzle 8 based on the venturi effect, a relatively low pressure environment is formed at the rear side of the nozzle 8, specifically, at the rear side of the nozzle in the flow direction of the polluted air, and a relatively high pressure environment is formed at the front side of the nozzle 8. At this time, the air supply pipeline connected to the header box 11 together with the exhaust pipeline is in a low-pressure state in the header box 11, the interior of the toilet 17 is also in a low-pressure state, and outdoor fresh air can be sent into the interior of the toilet 17 through the header box 11 under the action of pressure difference, so that ventilation of the toilet 17 is realized.
It should be noted that, in the ventilation system of the present embodiment, on the premise that no additional air supply fan is provided, the air supply capacity of the system is improved only by the connection pipe box 11, so that the ventilation effect of the ventilation system is greatly improved, and meanwhile, the cost and the energy consumption are reduced.
When the exhaust air inlet duct, the exhaust air outlet duct, the supply air inlet duct and the supply air outlet duct are all connected to the collecting box 11, although the polluted air is directly sprayed to the exhaust air outlet duct by the nozzle 8, it cannot be completely avoided that the polluted air blown into the collecting box 11 may reenter the toilet 17 from the supply air outlet duct, thereby causing 'tainting of odor'. Therefore, in order to avoid the above problem, the nozzle box 11 of the ventilation system according to the present embodiment is provided with the baffle 9, and the baffle 9 is located between the exhaust air path and the supply air path to separate the exhaust air path and the supply air path. Note that the separation of the exhaust air passage and the supply air passage in the present embodiment does not mean complete separation of the exhaust air passage and the supply air passage, and the baffle plate 9 is provided only to prevent the contaminated air in the exhaust air passage from entering the supply air passage.
To accomplish this, FIG. 2 shows one embodiment of the baffle 9. Specifically, the damper 9 may be provided with a check valve 10, and the check valve 10 allows the air flow to enter the discharge air passage from the supply air passage and prohibits the air flow from entering the supply air passage from the discharge air passage. The check valve 10 may be a check valve commonly used in the related art, and the detailed structure thereof will not be described in this embodiment.
Referring to fig. 2, when the nozzle 8 sprays the polluted air, the high-pressure airflow of the polluted air on the upper side of the baffle 8 is directly sprayed to the exhaust outlet pipeline, a relatively low-pressure environment is formed behind the nozzle 8 and is transmitted to the lower side of the baffle 8, and then the outdoor fresh air is introduced into the connection pipe box 11. Due to the check valve 10 provided on the baffle 9, the air flow on the upper side of the baffle 8 cannot be transmitted to the lower side of the baffle 8, thereby effectively preventing the contaminated air on the upper side of the baffle 8 from entering the lower side of the baffle 8.
Fig. 3 shows another embodiment of the baffle 9. Specifically, a notch may be formed in the baffle 9, and the notch is located behind the airflow direction of the airflow ejected from the nozzle orifice of the nozzle 8. At this time, the air flow ejected from the nozzle is high-pressure air flow, the notch is positioned behind the air flow direction of the ejected air flow, the ejected high-pressure air flow cannot return to the rear of the air flow direction and enters the lower side of the baffle plate 9 through the notch, and the polluted air on the upper side of the baffle plate 8 can be effectively prevented from entering the lower side of the baffle plate 8.
As a further optimization of the above two embodiments, a stopper may be provided in the baffle 9 to prevent the fresh air entering the header box 11 from the air inlet duct from entering the exhaust air passage and being discharged to the toilet 17. This blocking part can set up by the perpendicular to air flow direction, and the face of blocking part can be towards the port setting that is located the pipe box 11 in the air supply inlet pipeline, is blockked by the blocking part after the new trend gets into pipe box 11 by the air supply inlet pipeline, and then can prevent that the new trend from getting into the air supply wind path.
The air supply outlet pipeline and the air supply inlet pipeline can be approximately distributed in an L shape, specifically, the air supply inlet pipeline is arranged in parallel to the baffle 9, the air supply outlet pipeline is arranged perpendicular to the baffle 9, a port of the air supply outlet pipeline in the header box 11 is positioned on the lower side of the baffle 9, when fresh air enters the header box 11, the fresh air is blocked by the blocking part and flows towards the lower side of the baffle, at the moment, because the fresh air enters the toilet 17 communicated with the port of the air supply outlet pipeline in the header box 11, the fresh air can enter the toilet 17 through the air supply outlet pipeline.
In order to fully utilize the venturi effect at the nozzle of the nozzle 8, the pipe diameter of the first pipeline for forming the air exhaust air path inwards at the connecting pipe can be smaller than that of the air exhaust outlet pipeline, so that the air pressure formed by the polluted air in the first pipeline is larger than that formed by the polluted air in the air exhaust outlet pipeline, and the polluted air is conveniently exhausted through the air exhaust outlet pipeline.
Referring to fig. 2, the exhaust outlet duct includes an outdoor exhaust duct 5, the exhaust inlet duct may include an exhaust main duct 2 located in a top space of the toilet 17, and an exhaust fan 1 may be disposed on the exhaust main duct 2, the exhaust fan 1 being configured to blow polluted air in the toilet 17 to a port of the exhaust inlet duct located at the hose receiving box 11.
The main exhaust pipe 2 is provided with a plurality of exhaust branch pipes 3, the number of the exhaust branch pipes 3 can be the same as the number of the compartments 18 in the toilet 17, and the positions of the exhaust branch pipes 3 correspond to the positions of the compartments 18. In addition, other areas in the toilet 17 may also be provided with exhaust branch ducts 3 for enhancing the ventilation of the toilet 17.
The free ends of the exhaust branch pipes 3 may be arranged towards the bottom space of the toilet 17, and the position of the free ends of the exhaust branch pipes 3 in the compartment 18 may in particular correspond to the position of the toilet bowl 19.
The side surface of the exhaust branch pipe 3 close to the free end thereof can be provided with a plurality of first exhaust openings 6, and the first exhaust openings 6 can introduce polluted air in a toilet 17 into the exhaust branch pipe 3 from the side surface of the exhaust branch pipe 3; furthermore, the end of the free end of the exhaust branch 3 can be provided with a second exhaust opening 7, which second exhaust opening 7 is used to introduce the polluted gas in the toilet 17, in particular at the bottom of the toilet 17, into the exhaust branch 3.
Referring to fig. 2, the supply air inlet duct may be specifically a supply air duct 12, and a filter 14 may be disposed on the supply air inlet duct, where the filter 14 is configured to filter fresh air flowing through the supply air inlet duct. The filter 14 may be a filter commonly used in the related art, and the specific structure thereof will not be described in detail in this embodiment.
In addition, air supply inlet pipeline can also be provided with heat exchange coil 15, and this heat exchange coil 15 is used for heating the new trend of circulation in the air supply inlet pipeline. Specifically, the heat exchange coil 15 may be directly disposed in the air supply inlet duct, or may be wound around the air supply inlet duct. The heat exchanging coil 15 can be a resistance type electric heating coil, or a pipe for circulating a heat exchanging medium, which can be a gaseous fluid, such as steam, or a liquid fluid, such as a heating water fluid.
In addition, when the heat exchanging coil 15 is a pipe, the heat exchanging medium may be a refrigerant, such as a gaseous fluid or a liquid fluid at a temperature lower than room temperature, so as to cool the fresh air in the air supply inlet pipe.

When ventilating, an exhaust pipeline and an air supply pipeline are arranged between the toilet and the outside, and a relatively low-pressure environment is formed in the connecting pipe box through the nozzle, so that outdoor fresh air is introduced into the toilet from the air supply pipeline.
