Description

[Detailed description of the invention] The present invention relates to an operating mechanism for a bathtub.The purpose of this invention is to effectively utilize the circumferential surface of the operating shaft to make the whole smaller and simpler, and to reduce the opening at the bottom of the main body. A function for opening and closing passages to a plurality of gas burners can be added to the closing lid.

Conventionally, this type of operating mechanism has a distribution chamber through which an operating shaft A passes, an electromagnetic safety valve, a pilot gas valve, and a main gas valve that are opened and closed by rotation of the operating shaft around the operating shaft, as well as an electromagnetic safety valve chamber and a pilot gas valve. An operating mechanism having a main body in which a valve chamber, a main gas valve chamber, and a gas governor chamber are arranged in a plane, and the distribution chamber and the gas governor chamber are opened downward is known, for example, from Japanese Patent Application Laid-open No. 12724/1983. The example has only a single bath function, and if you try to use it for a so-called circulating hot water bath pot with a water heater, you will need to connect the passage from the main gas outlet of the operating mechanism to the bath burner and the hot water burner. A bath gas valve and a hot water supply gas valve are provided in each passage, and in particular, the bath gas valve has a cam attached to it by extending the operating shaft of the operating mechanism downward. However, it would be easy to devise an operating mechanism for a circulating hot water bath pot from this conventional example by simply adding a mechanism. It wasn't.

The present invention is based on the current state of the prior art and aims to provide a concrete configuration that can obtain an operating mechanism for a circulating hot water bath pot in a very rational manner by reusing the main body of the conventional operating mechanism.

For this purpose, the present invention connects the main body shown in A above to the lower opening of the main body, which has a branch chamber communicating with the B gas governor chamber and a cam chamber through which an auxiliary shaft connected to the operating shaft passes. At the same time, a connecting body is connected to the lid body, which has a passageway to the main burner for the bath that communicates with the C cam chamber, and a passageway to the main burner for hot water supply that communicates with the branch chamber and is provided with a gas valve for hot water supply. , B, and C, and its effects include:
First, for the main body of A, which is the basic configuration shown in the conventional example, a configuration is obtained in which the main gas flow is branched into the main burner for bathing and the main burner for hot water supply by connecting the lid body B, and then, By connecting the connecting body C and providing an opening/closing mechanism (gas valve for hot water supply) to the main burner for hot water supply, a complete operation mechanism for a circulating hot water bath pot can be obtained, which is a rational docking operation mechanism. We are now able to provide this service.

Below, the present invention will be explained in detail with reference to the illustrated embodiment. Fig. 1 is an explanatory diagram showing the overall configuration of a circulating water supply type bath pot, where 1 is a bath pot, 2 is an instantaneous water heater, and 3 is a Bathtub, 4
5 is a water supply channel connected to the instantaneous water heater 2, 5 is a shower, 6 is a hot water tap, and 7 is a water pressure response device, which opens and closes a gas valve (described later) using a pressure difference created by a venturi 8.

is the main burner of instantaneous water heater 2, 12 is main burner 1
Pilot burner common to 0 and 11, 13 thermocouple, 1
Reference numeral 4 denotes the main body of the operating mechanism, which will be explained with reference to FIGS.
The gas passage from the gas outlet to the gas outlet is partitioned.

A cam 17 is attached to the operating shaft 15.
An electromagnetic safety valve 18, a pilot gas valve 19, an air purge valve 20,
A main gas valve 21 is provided.

The main body 14 includes an electromagnetic safety valve chamber 22, a distribution chamber 23 through which the operating shaft 15 passes, a pilot gas valve chamber 24, and an air purge valve chamber 2.
5. Consisting of a main gas valve chamber 26 and a gas governor chamber 28 in which a gas governor is provided, each of these chambers is arranged in a plane within the main body 14, and the main body 14 is where the electromagnetic safety valve chamber 22, the distribution chamber 23, and the gas governor chamber 28 are located. The lower part is open.

The pilot gas valve chamber 24 and the air purge valve chamber 25 are located in the main body 1.
It opens on the side of 4.

The main gas valve chamber 26 is divided into sections so as to communicate from the distribution chamber 23 to the gas governor chamber 28.

29 is a lid connected to the lower opening of the main body 14 to close off the distribution chamber 23, and has a passage 31 from the gas port 16, a branch chamber 33 equipped with a gas valve 32 for the bath kettle, and a cam chamber 34;
The branch chamber 33 communicates with the gas governor chamber 28 , and the passage 31 communicates with the electromagnetic safety valve 22 .

An auxiliary shaft 35 connected to the operating shaft 15 is provided through the cam chamber 34, and a cam 36 is attached to the auxiliary shaft 35, so that the bath gas valve 32 can be opened and closed by rotation of the operating shaft 15.

37 is a connecting body connected to the branch chamber 33 and cam chamber 34 of the lid body 29, and has a passage 38 to the bath main burner 10 and a passage 39 to the hot water supply main burner 11, and the passage 39 has a hydraulic response device. A gas valve 40 for hot water supply, which is opened and closed by means 7, is provided.

The present invention has the above-mentioned structure, and gas enters the distribution chamber 23 from the gas port 16 through the electromagnetic safety valve chamber 22, and is divided into the pilot gas valve chamber 24, the air purge valve chamber 25, and the main gas valve chamber 26, respectively.

The gas that has flowed into the main gas valve chamber 26 enters the gas governor chamber 28 and passes through the passage 3 through a branch chamber 33 provided in the lid body 29.
9 and a cam chamber 34, and the cam chamber 34 communicates with a passage 38.

As described above, the present invention makes effective use of the circumferential surface of the operating shaft 15, making it possible to downsize and simplify the overall structure, and also to open the lower part of the main body 14, thereby making it easier to assemble each valve. It's easy.

In addition, the safety valve 18, pilot gas valve 19, and main gas valve 21, which are basically required for gas appliances, are arranged inside the main body 1, so the simplest gas appliance has a gas inlet and a gas outlet to the main burner. It can be easily reused by closing the lower opening of the main body with a lid formed with the main body.

Furthermore, by connecting the lid body 29 that forms the branch chamber 33 and the cam chamber 34 and connecting the auxiliary shaft 35 to the operation shaft 15, it is possible to add the function of opening and closing passages to multiple gas governors. By connecting the connecting body 37 provided with the water pressure-responsive gas valve 40, there are practical effects such as the ability to easily configure an operating mechanism that can be applied to a circulating hot water bath pot.
