Abstract

PURPOSE:To reduce the deterioration of antenna performance and to efficiently and stably transmit/receive signals in a wireless remote control type hot water feeder operation device utilizing radio waves. CONSTITUTION:An antenna 17 for a communication unit 13 in a controller 2 for transmitting/receiving control signals to/from a wireless remote controller 12 is arranged rectangularly to a vertical pipe 10 in a pipe shaft and constituted so as to be extended/contracted in the horizontal direction. Consequently the antenna 17 is not restricted by the upper face 8 of the pipe shaft and the performance deterioration of the antenna due to the pipe 10 can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater operating device for heating water with gas, petroleum, electricity or the like.

[0002]

2. Description of the Related Art In recent years, with the widespread use of water heaters, inventions have been made that improve the operation method of water heaters (for example, Japanese Patent Publication Sho 6).
2-48144).

A conventional water heater operating device will be described below. As shown in FIG. 3, the water heater 1 installed outdoors
The controller 2 arranged inside the room and the remote controller 3 installed in the room are connected by a remote controller cable 5 penetrating a block of a pipe shaft or a concrete wall 4, and the control signal from the remote controller 3 is a remote controller cable. It is configured to be transmitted to the hot water heater 1 via 5.

In a collective building such as a condominium, the water heater 1 is arranged in a pipe shaft having a door 6 near a top surface 8 apart from a floor surface 7. Exhaust port 9 of water heater 1
Is guided through the door 6 to the outside.

In the figure, 10 is a vertical pipe for gas, water, electricity, etc. in the pipe shaft, and 11 is a pipe for supplying from the vertical pipe 10 what is used in the water heater 1.

Further, as shown in FIG. 4, when the water heater 1 is remotely operated by the wireless remote controller 12 using radio waves or the state of the water heater 1 is remotely monitored, the water heater 1 is installed inside the water heater 1. The configuration is such that transmission / reception is performed with an antenna 14 mounted in the vertical direction of a communication unit 13 of an installed controller (not shown). In the figure, 15 is a wall of the house, and 16 is a pipe to the water heater 1.

[0007] In a collective building such as a condominium, when the water heater 1 is installed in the pipe shaft and operated by the wireless remote controller 12, the antenna 14 hits the upper surface 8, so that the performance of the antenna 14 is sufficient. There is a problem that there is no space for arranging an antenna of a length, and vertical pipes 10 for water supply pipes and strong electric field pipes are vertically arranged in the pipe shaft. Therefore, there is a problem that the output of the antenna 14 is reduced.

[0008]

As described above, in the conventional configuration, when the water heater 1 is installed in the pipe shaft and operated by the wireless remote controller 12, the length of the antenna 14 is restricted and the performance is deteriorated. There is a problem that the performance of the antenna 14 is deteriorated due to the influence of the vertical pipe 10 without being increased.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an operating device for a water heater in which the deterioration of the performance of the antenna is reduced.

[0010]

In order to achieve this object, a water heater operating device according to the present invention is arranged such that an antenna of a communication unit of a controller for transmitting / receiving a control signal to / from a wireless remote controller is installed vertically in a pipe shaft. It is arranged so as to be orthogonal to the piping and is configured to be capable of expanding and contracting in the horizontal direction.

[0011]

In this structure, the antenna is not restricted by the upper surface of the pipe shaft, and the deterioration of the antenna performance due to the vertical piping is reduced.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 showing an embodiment of the present invention, the same parts as those described in the above-mentioned conventional example are designated by the same reference numerals and the description thereof will be omitted.

The feature of this embodiment is that, as shown in FIGS. 1 and 2, a telescopic antenna 17 is provided in the communication unit 13 of the controller 2 of the water heater 1 at right angles to the vertical pipe 10 in the pipe shaft. It was installed in the horizontal direction.

As described above, according to this embodiment, the antenna 17 of the communication unit 13 is connected to the vertical pipe 1 in the pipe shaft.
By mounting the antenna 17 in the horizontal direction orthogonal to 0, the antenna 17 is not hindered by the upper surface 8 of the pipe shaft, and the performance of the antenna 17 can be prevented from being weakened by the electric field from the vertical pipe 10, and efficient and stable transmission / reception can be performed.

Further, by making the antenna 17 telescopic, the antenna 17 can be extended into a vacant space even when there are obstacles such as pipes and meters in the pipe shaft, so that the antenna 17 can be input and output. Can be increased.

[0017]

As is apparent from the above description, according to the present invention, the antenna of the communication unit of the controller for transmitting / receiving the control signal to / from the wireless remote controller is arranged so as to be orthogonal to the vertical pipe in the pipe shaft. In addition, by adopting a structure that can be expanded and contracted in the horizontal direction, it is possible to realize an excellent water heater operating device in which the deterioration of the performance of the antenna is reduced.
