Description

  The present invention relates to a pumping device that is connected to and provided on the downstream side of a drainage device, a reservoir is shaped to store water therein, and includes a pumping pump inside.

  In order to realize indoor relocation that flexibly responds to changes in lifestyles, technological development of a pumping device that can pump the drainage of equipment with a flexible pipe and can be moved more easily than in the past has been underway.

  In some of the pumping apparatuses shown in the past, when the pump is stopped, the water present in the raised drainage channel is returned to the casing of the pump, and the pump is almost submerged by the water. Then, when new waste water flows in here, the water level in the casing immediately rises to the position of the upper sensor, so that it can be driven immediately. (For example, see Patent Document 1).

  However, as shown in Japanese Patent No. 2579023, in a pumping device in which the pump is almost submerged when the pump is stopped, the allowable amount for receiving the next drainage is too small. Although it seems that there is no problem because the pump is driven immediately, the discharge capacity of the pump changes due to the influence of the downstream piping condition, so it can not be said that it can be discharged at any time at a flow rate higher than the inflow of the next drainage. . In addition, when considering connection to various drainage devices with high versatility, there are also devices with large instantaneous flow rates such as toilets, so that the following pumping device with a small allowable amount of drainage cannot be supported. Seem.

Even when the pump is stopped, even if the water level in the pumping device is not so high, depending on the shape of the downstream piping, a part of the drainage discharged from the pumping device once flows backward and returns to the pumping device. It may be possible to come. Even when drainage from the drainage device itself is not performed, when the drainage device is cleaned, some water may flow into the pumping device and the water level may rise. Therefore, considering the allowance of the next drainage, it is better to keep the water level as low as possible before the inflow.
Japanese Patent No. 2579023

This invention solves the said subject, and it aims at providing the pumping apparatus which can ensure an allowable amount to accept this waste_water | drain before inflow of each drainage equipment from each drainage device to a pumping device.
Here, the drainage device is a toilet, a urinal, a bathtub, a washroom in a bathroom, a sink, a kitchen sink, and the like.

In order to solve the above-mentioned problems, in the pressure feeding device according to the first aspect of the present invention, the storage tank is connected to and provided on the downstream side of the drainage device, the storage tank has a shape that can store water therein, and the pressure pump inside. A pumping device in which a sufficient amount of sealed water is held to cut an edge between the storage tank and the sewer when the pumping pump is stopped, and the drainage device and the pumping device are connected by a drainage inflow passage. And an opening / closing portion that opens and closes the drainage inflow passage, and a system activation switch that controls driving of the drainage device or the pumping device, and drives the pumping pump in response to a signal from the system activation switch, and the effluent from the drainage device to release the closing portion after starting the discharge of water to flow into the storage tank, pre-Symbol pumping port was discharged outside the drainage of the storage tank by driving the pressure pump The flop is stopped, sufficient sealing water were assumed to be retained within the reservoir to a subsequent new water cut edge of the the reservoir and sewage by supplying to the storage tank.
As a result, the drainage of the storage tank in the pumping device starts to be discharged before the drainage from the drainage device flows in, and the water level of the storage tank is lowered, so that there is enough room. it can. In addition, depending on the piping conditions, there may be a case where a part of the drainage discharged from the pumping device once flows back into the pumping device due to the shape of the downstream piping, so that an allowable amount for accepting this can be ensured. Further, a part of the drainage from the drainage device can be used as a sealed trap, and there is no need to provide another sealed trap, and the shape from the drainage device to the sealed trap can be stored compactly. Furthermore, since the sealed water starts to be pumped and discharged before the next drainage flows in, the allowable amount for the next drainage can be ensured.

According to a second aspect of the present invention, the water pressure sensor for detecting the water level in the storage tank is provided, the pressure pump is driven by a signal from the system start switch, and the water level sensor is a water level in the storage tank. After detecting a predetermined water level lower than the water level at the entrance of the drainage inflow passage, the opening / closing part is released to allow drainage from the drainage device to flow into the storage tank, and the pumping pump is driven to after draining drainage to the outside, said pressure pump stops, the supply of new clean water so that the entrance to the predetermined water level is lower than the water level of the drainage inlet passage into said reservoir, said reservoir It was assumed that enough sealed water was held inside the storage tank to cut the edge between the tank and the sewer.
As a result, the drainage from the drainage device can be allowed to flow into the storage tank after the water level in the storage tank has been reliably reduced, so that it is possible to ensure the allowable amount for drainage from the drainage device in the storage tank. it can. Therefore, depending on the piping conditions, it is possible to reliably prevent a problem that a part of the drainage once discharged from the pumping device flows back into the pumping device due to the shape of the piping downstream of the drainage device.
In addition, the water entering the storage tank and the discharge from the storage tank can be controlled by the water level, and the drainage water in the storage tank can be controlled in a sequence appropriate for the system.

Since the pumping pump is driven and the wastewater in the storage tank is discharged, the wastewater from the drainage device is allowed to flow into the pumping device, so even if the storage tank is made compact, the wastewater from the drainage device is securely stored. It is acceptable in the tank.

An embodiment of a pressure feeding device according to the present invention will be described with reference to the drawings. FIG. 1A shows a system in which a pressure feeding device is connected to a bowl 6 of a toilet bowl, and an opening / closing part 7 is provided at the connecting part. At this time, the state of each part is as shown in FIG. 2 (a), and is based on a signal from a water level sensor provided in the pumping device. The user sits on the toilet seat ("use start" in Fig. 2 (a)), excretes, and turns on the manual washing switch when finished. Further, during this period, the bowl surface starts to be cleaned, and at the same time, the pumping is performed to allow new drainage in the pumping device, and the water level in the device is reduced. Here, the bowl cleaning and the pumping start of the pumping device, that is, the system start switch ON is assumed to be simultaneous, but they may be operated individually, and in particular, the system start switch is set to an appropriate water level at the time when the pumping is performed. It is desirable to adjust so that it becomes.
When the water level sensor senses that the water level has dropped sufficiently, the opening / closing part opens and drainage to the pumping device begins. When the water level rises and cleaning is completed, the opening / closing part is closed, and the waste water in the pumping device is pumped. The function as a normal toilet has been described so far, but since this toilet does not have a trap, a sealing water is provided in the pumping device and this is used as a trap. That is, after the pumping is finished and the water level in the pumping device is low, fresh clean water is supplied until the water level reaches an appropriate level. As a result, a state that is hygienic and ideal for the user is maintained. Here, the appropriate water level sensed by the water level sensor is preferably a water level lower than that of the opening 7. Thereby, when draining from a toilet bowl to a pumping apparatus, the drainage in a pumping apparatus does not flow backward to a toilet bowl. More preferably, it is preferably 2/3 or less from the bottom surface of the storage tank. Thereby, in the initial stage of drainage from the toilet, even if the amount of drainage is large, the backflow from the storage tank to the toilet can be more reliably prevented.

  Hereinafter, an embodiment of a pumping device according to the present invention will be described with reference to the drawings. FIG. 1A is a side view showing an embodiment when a bowl 6 of a toilet bowl is connected to the pressure feeding device 1. This bowl 6 does not have a trap in its downstream part. A normal drainage device has a drainage path that also serves as a trap, but here an opening / closing part 7 is provided instead. In this case, there is no trap that cuts the edge of the sewer, but the drainage 4 can be held as sealed water in the pressure feeding device 1 to form a trap. Then, in order to secure a sufficient space for allowing this sealed water to flow before the next drainage flows, the system start switch 51 is turned on to drive the pumping pump 2 and to press the pumping device 1. It is necessary to sufficiently reduce the remaining amount of waste water inside.

  FIG. 1B similarly shows a case where the pressure feeding device 1 is connected to a toilet, but here the toilet itself has a trap. For this reason, it is not necessary to supply water as sealing water in a pumping apparatus like Fig.1 (a). However, in a hygienic and user-friendly manner, it is desirable to store clean water in the box at the end of a series of operations.

  FIG. 2A is a diagram showing the time course of Tokyo such as the water level of the system in FIG. 1A and FIG. 2B is the diagram in FIG. First, drainage is stored in the pumping device with a certain level of water ("use start" in FIG. 2). As shown in FIG. 1 (a), if necessary, this amount is sufficient to cut off the edge of sewage as sealed water. Next, the pressure pump 2 is driven by the system start switch 51 to pump and discharge the drainage, lower the water level in the pumping device, and secure a sufficient space to allow drainage ("water level reduction" in FIG. 2). Thereafter, if necessary, the pumping pump is temporarily stopped, drainage is allowed to flow from the drainage device into the pumping device, and the water level in the pumping device rises (“drainage inflow” in FIG. 2). Then, the pumping pump 2 is driven again, and the drainage is pumped and discharged by an appropriate amount (“pumping discharge” in FIG. 2). After that, if necessary, enough water must be secured in the pumping device so that the water can be sealed, so cleaning water is added until the water level reaches an appropriate level (“sealed water supply” in FIG. 2). ) When using a drainage device that already has a trap as shown in Fig. 1 (b), it is not necessary to provide sealed water, but the inside will not dry out and filth will not stick. It is desirable to add as much clean water as possible into the pumping device.

The pump 2 must be driven before the inflow of drainage from the drainage equipment. In FIG. 2, it is the same as when the user presses the manual cleaning switch after excretion, but the present invention is not limited to this, and any control method may be used. The pump is driven by turning on the system start switch at an appropriate time.
In FIG. 2, the subsequent flow of water supply / drainage follows the water level sensor 9 provided in the pressure feeding device. However, if the flow rate can be known, it may be controlled using a timer.

FIG. 3 shows a pumping device. As shown in FIG. 3 (a), when a certain amount of drainage 4 already exists in the pumping device 1, and when drainage from the drainage device further flows from this state, sufficient space is allowed for the pumping device 1 to allow this. Does not exist and may overflow from the pumping apparatus 1. Therefore, a drainage control means (not shown) is provided, and the pumping pump 2 is driven before the pumping device 1 receives the drainage from the drainage device, so that the remaining amount of the drainage 4 in the pumping device 1 is sufficient as shown in FIG. When a toilet bowl is connected to the pressure feeding device 1, it is more desirable to crush filth and toilet paper and pump it with a narrower pipe, so that the construction and renewal of the discharge pipe can be performed. It can be carried out simply and at low cost. Furthermore, by using a flexible tube as the discharge tube, the flexibility that is an advantage of the pressure feeding device 1 can be further enhanced.
An embodiment of the pulverizing unit 41 when filth and toilet paper are pulverized will be described. Any material can be used as long as it can pulverize filth and can be pumped and discharged by a thin tube. For example, as shown in FIG. It is conceivable that the shaft is the same as the motor 22 and operates as the motor 22 rotates. Thereafter, the fine tube 19 is pumped and discharged to the outside.

  FIG. 4 shows a case where a basin is connected to the pressure feeding device 1 as the drainage device 8 instead of the toilet. Since the basin is provided with a trap on its downstream side, it is not necessary to provide sealing water in the pressure feeding device. In this way, it is possible to provide a pumping device to drainage equipment other than the toilet, and it is also possible to pump the wastewater from a plurality of drainage equipment depending on the processing capability of the pumping device.

It is a side view of the pumping apparatus at the time of connecting with the toilet bowl which is one Embodiment of this invention. It is the figure which showed the time course of the water level in the pumping apparatus which is one Embodiment of this invention. It is a side view of the pumping apparatus which is one Embodiment of this invention.
