Description

  Aspects of the invention generally relate to a tank apparatus.

  For example, there is a washing water tank provided in a sanitary washing device or the like. The washing water tank stores washing water and supplies the washing water to, for example, a bowl portion of a western-style seated toilet. In the washing water tank, condensation may occur due to a temperature difference between the temperature of the water inside the washing water tank and the temperature outside the washing water tank. If dew condensation occurs, it may affect various devices provided in the sanitary washing apparatus.

  On the other hand, there is a cleaning water tank with improved airtightness in a connecting portion of a pipe to the cleaning water tank. However, by increasing airtightness at the pipe connection to the wash water tank, etc., when the pipe connection at the wash water tank is sealed, the momentum of the toilet flushing water discharged from the wash water tank is weakened. There is a problem.

  On the other hand, there is a sanitary washing device in which a vent is provided in a drain cap (Patent Document 1). The vent described in Patent Document 1 ensures air permeability to a drain pipe connected to the drain by restricting the flow of water flowing into the drain.

  However, even if the vent hole is provided in the drain cap, if a large amount of water flows at once, the water may enter through the vent hole and be discharged into the washing water tank. In the case where a large amount of water flows all at once, there is room for improvement in that there is a possibility that the air permeability at the vent cannot be secured.

The direction. In the present specification, “lower” or “lower” refers to the direction opposite to the upper side.

  The hand-washing bowl 131 has a drain outlet 133 provided at the lower end. For example, water discharged from the spout 280 hits the surface (bowl surface) of the hand-washing bowl 131 and is guided to the inside of the tank body 200 through the drainage port 133.

  Here, “front” or “front” in the specification of the present application refers to a direction parallel to the installation surface 801 and a direction toward the drain outlet 133 when viewed from the spout 280. In the present specification, “rear” or “rear” refers to a direction opposite to the front.

  As shown in FIG. 2, the tank body 200 is provided inside the casing 100. As illustrated in FIG. 3, the tank main body 200 includes a tank unit 210, a first tank lid 220, and a second tank lid 230. The tank unit 210, the first tank lid 220, and the second tank lid 230 are engaged with each other to form at least a part of the outer shape of the tank main body 200. The first tank lid 220 is provided on the tank unit 210. The second tank lid 230 is provided on the first tank lid 220. However, the tank main body 200 does not necessarily have the tank portion 210, the first tank lid 220, and the second tank lid 230, and may be formed by one member.

  The tank part 210 has a hollow shape and can store water in the tank part 210 itself. In other words, the tank body 200 can store water in the tank body 200 itself. For example, water stored in the tank body 200 is used as water for cleaning the bowl portion of the toilet bowl 800.

  The second tank lid 230 has a drain hole 231 and an intake hole 233. In other words, the tank body 200 has a drain hole 231 provided in the upper part and an intake hole 233 provided in the upper part. The drainage hole 231 passes through the second tank lid 230 and connects the inside of the tank body 200 and the outside of the tank body 200. The intake hole 233 passes through the second tank lid 230 and connects the inside of the tank body 200 and the outside of the tank body 200.

  The water discharged from the spout 280 passes through the drain port 133 of the hand-washing bowl 131 and is guided into the tank unit 210 through the drain hole 231 of the second tank lid 230.

Here, in order to suppress the occurrence of condensation due to the temperature difference between the temperature of the water stored inside the tank body and the temperature outside the tank body, for example, a hand-washing lid, Consider the case where the connection between the tank lid and the tank lid is sealed. In this case, when the water stored in the tank body is discharged, negative pressure is generated, so that the water discharged from the tank body is compared with the case where the connection portion is not sealed. Momentum may be weak.
Also, consider a case where the drain cap provided at the drain outlet of the hand-washing bowl has an intake hole that is different from the drain hole. In this case, the air intake hole of the drainage cap regulates the flow of water flowing into the drainage port of the handwashing bowl, so that air permeability is secured at the connection portion between the handwashing lid and the second tank lid. . However, if a large amount of water flows into the drain of the hand-washing bowl, the air intake hole of the drain cap may not be able to ensure air permeability.

  On the other hand, the tank main body 200 of this embodiment has the drainage hole 231 provided in the upper part, and the intake hole 233 provided in the upper part. The drain hole 231 allows the water that has passed through the drain port 133 of the hand-washing bowl 131 to pass into the tank body 200. The intake hole 233 can take air outside the tank body 200 into the tank body 200. That is, the air outside the tank body 200 is taken into the tank body 200 through the intake holes 233.

  According to the present embodiment, the tank body 200 has the intake holes 233 different from the drain holes 231, so that water can be prevented from passing through the intake holes 233.

Therefore, as shown by arrows A3 and A4 in FIG. 6, when the water stored in the tank body 200 is discharged, the air outside the tank body 200 is changed to the hand-washing lid 130 and the second tank. It passes through the space between the lid 230 and is sucked into the tank unit 210 through the intake hole 233. Thereby, it can suppress that the momentum of the water discharged | emitted from the inside of the tank main body 200 becomes weak.

  Further, when the water stored in the tank body 200 is discharged, the air around the drain hole 231 is more easily sucked into the tank body 200 than before the water is discharged. In the present embodiment, since the intake holes 233 are provided around the first outer wall 235, when water is discharged, the air around the drain holes 231 passes through the intake holes 233 to the inside of the tank body 200. It is easy to be inhaled. Thereby, air permeability can be ensured in the connection part between the hand-washing lid 130 and the second tank lid 230, and water can be discharged smoothly.

  Furthermore, since the intake hole 233 is provided around the first outer wall 235, even when a large amount of water flows into the drain port 133, it is possible to prevent water from flowing into the intake hole 233. Therefore, air outside the tank main body 200 can be reliably taken into the tank main body 200 through the intake hole 233. Thereby, even when a large amount of water flows into the drain outlet 133, air permeability can be ensured at the connection portion between the hand-washing lid 130 and the second tank lid 230, and the water can be discharged smoothly. It can be carried out.
