In this Western-style flush toilet, if the user adds an operation and then operates an operation switch, washing water is supplied from the washing tank to the Western-style toilet body, and the Western-style toilet body can be washed. Moreover, functional devices, such as a deodorizing apparatus, can provide a various function to a western-style toilet body.
[0004]
[Problems to be solved by the invention]
However, in the conventional Western-style flush toilet, the base plate is fixed to the Western-style toilet body, and a washing tank, a tank cover, and the like are provided on the base plate. For this reason, the rear upper surface of the western-style toilet body is always covered with those members leaving a slight gap, and even if dirt such as urine adheres to the upper surface of the rear part through the gap, it is difficult to remove the dirt. It was. For this reason, an unpleasant odor is generated due to the dirt, and it is unsanitary.
[0005]
In this regard, the Western-style flush toilet disclosed in JP 2000-33051 A, JP 2000-104307 A, or JP 2001-231715 A can solve the problem. That is, in these Western-style flush toilets, the base plate is composed of a rear base plate that is fixed to the Western-style toilet main body and on which at least the washing tank is placed, and a front base plate that can be moved up and down by a lifting device with respect to the rear base plate. ing. The tank cover includes a rear cover fixed to the rear base plate and a front cover fixed to the front base plate. In these Western-style flush toilets, if the front base plate is raised by the lifting device, the front cover is raised together with the front base plate, so that the rear upper surface of the Western-style toilet body can be exposed. For this reason, it is possible to easily remove dirt such as urine adhering to the upper surface of the rear part of the Western-style toilet body, and it is possible to prevent the generation of a strange odor due to this dirt and to be hygienic.
[0006]
However, in the Western-style flush toilets described in the above publications, the tank cover is composed of a rear cover and a front cover, and only the front cover is fixed to the front base plate. For this reason, when the front base plate is raised, only the front cover is raised. In this state, the front cover does not support the rear cover, and the front cover stands up in an unstable state. In particular, in this type of Western style flush toilet, it is easy to adopt a front cover that is light in weight due to its thin wall thickness, so that the front cover can be easily bent. I'll be stuck. For this reason, if excessive force is applied to the front cover from the outside with the front base plate raised, the front base plate may deform the part that fixes the front cover or the front cover itself. Sex is a concern.
[0007]
In this regard, it is conceivable to adopt a base plate composed of a rear base plate fixed to the Western-style toilet body, and a front base plate which is provided so as to be movable up and down by a lifting device with respect to the rear base plate and to which the entire tank cover is fixed. . If this is the case, the entire tank cover is lifted and lowered by the front base plate, so that it is possible to solve the low durability due to the lift of only the front cover.
[0008]
However, even if the entire tank cover is moved up and down in this way, the tank cover tends to be inclined while being raised and in the raised state. In particular, since the tank cover accommodates a cleaning tank having a relatively high height, the center of gravity of the tank cover is on the upper side and the tank cover is easily inclined. Also, since the tank cover is provided with a relatively heavy toilet seat device, the load from the toilet seat device tends to tilt the tank cover forward. If the tank cover is moved up and down in an inclined state in this way, an excessive force may act on the tank cover itself and damage the tank cover, and an unreasonable force also acts on the lifting device to damage the lifting device. Connections and eventually durability are still a concern.
[0009]
This invention is made | formed in view of the said conventional situation, It is made into the problem which should be solved to provide the western style flush toilet bowl which is hard to generate | occur | produce an odor, is hygienic, and was more excellent in durability.

Therefore, the Western-style flush toilet of the present invention is less hygienic and is hygienic and more durable.
[0015]
It is preferable that there are two or more guide means. In this case, when the entire tank cover is raised and lowered by raising and lowering the front base plate by the raising and lowering device, the tank cover is guided by two or more guide means. For this reason, the guide of the tank cover is more reliably performed, and the tank cover is more difficult to be inclined while being raised and in the raised state. Further, since the force applied to the guide means is distributed to two or more guide means, the force applied to each guide means is reduced. For this reason, the guide means is not easily damaged, and the durability is excellent.
[0016]
In this case, it is preferable that the guide means is provided in the front-rear or left-right direction. In this case, the guide of the tank cover by the guide means is performed in a balanced manner from the front and rear or from the left and right, and the guide of the tank cover by the guide means can be further ensured. For this reason, it is extremely excellent in durability. [0017]
The guide means may be composed of a vertically extending ridge formed on one of the partition wall and the tank cover and a vertically extending guide groove formed on the other of the partition wall and the tank cover. In this case, the ridge formed on one of the partition wall and the tank cover can slide along the guide groove formed on the other side of the partition wall and the tank cover, and the entire tank cover is smoothly guided. .
