Abstract

PURPOSE:To easily move a room temperature detecting element to an optimum position corresponding to the installation position. CONSTITUTION:A thermistor 8 is provided with a long lead wire 9 and attached by a holder 7 so that its mounting position can be freely changed within a given range when necessary. Thus, the thermistor 8 can be mounted at an optimum position within the given range corresponding to the installation location, so that proper room temperatures are detected at an optimum position.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room temperature detection element in an air conditioner, which is an indoor unit of an air conditioner.

0002

BACKGROUND OF THE INVENTION Many air conditioners (including heating-only machines and cooling-only machines) operate under control based on temperature information based on room temperature. For example, Utility Model No. 55-28841
This is as disclosed in the publication No. Conventional room temperature detection elements are fixed at a proper location in the main body of an air conditioner by means of a mounting bracket or the like at the time of shipment from a factory in a state where they are not intended to be removed. The fixed position is a position where there are few disturbance requirements and where the room temperature can be detected as appropriately as possible, and is often near the indoor circulating air intake.

[0003] In the above-described conventional air conditioner, operating information is input to the control device based on the detection output from the room temperature detection element, and based on this, controlled operation is carried out to create an appropriate environment.

0004

[Problem to be Solved by the Invention] In the conventional air conditioner configured as described above, if the room temperature detection element is an isolated system, it will be located at an appropriate functional position, but the installation location of the air conditioner itself In some cases, the installation position may be extremely inappropriate. In other words, depending on where the air conditioner is installed, it may be located in a position where it is heavily influenced by outside air or may be located near other heat sources, making it impossible to detect the appropriate room temperature, and as a result, the air conditioner may appear to be will end up malfunctioning.

[0005] The present invention has been made to solve the conventional problems, and an object of the present invention is to provide an air conditioner in which a room temperature detection element can be easily moved to an optimal installation location.

[0006]

[Means for Solving the Problems] The air conditioner according to the present invention is such that the lead wire of the room temperature detection element is made long in advance, so that the mounting position can be changed freely within a predetermined range if necessary. It is.

[0007]

[Function] In the air conditioner according to the present invention, the room temperature detection element can be installed at the most suitable position within a predetermined range depending on the installation location, and the appropriate room temperature is detected at the optimal position of the installation location. .

[Embodiment] Fig. 1 is a front perspective view showing the entire air conditioner according to an embodiment of the present invention, and Fig. 2 is a rear perspective view.
FIG. 3 is an explanatory diagram showing the mounting portion of the room temperature detection element, and FIG. 4 is an explanatory diagram showing the operation of the room temperature detection element. The air conditioner of this embodiment includes a forced air supply/exhaust type combustor (not shown) using a gas heat source that functions for heating and a heat exchanger (not shown) that functions for cooling in a box-shaped main body 1. The working fluid passage of the cooling heat exchanger is connected to an outdoor unit (not shown) by piping, and is supplied with refrigerant. A hot air outlet 2 is provided at the front of the main body 1, and a cold air outlet 3 is provided at the center of the upper surface of the main body 1.
An indoor air intake port 4 is provided at the bottom of the unit. Indoor air sucked in through the intake port 4 receives heat from combustion in the combustor during heating and is blown out as warm air into the room from the warm air outlet 2, and during cooling, it is cooled by a cooling heat exchanger and sent to the cold air outlet. From 3 onwards, the air is blown into the room. The cold air outlet 3 has a rectangular opening on the front side of the upper surface of the main body 1, and a vane 5 is attached thereto as shown in FIG. The vane 5 is a lid that closes the cold air outlet 3 when not needed, opens the cold air outlet 3 during cooling operation, and is a functional component that swings within a predetermined range to change the direction of the cold air outlet. At the bottom of the main body 1, that is, near the intake port 4, a thermistor 8, which serves as a room temperature detection element, is temporarily fixed to a crank-shaped metal fitting 6 with a holding metal fitting 7. The lead wire 9 of this thermistor 8 is set long in advance, and the thermistor 8 is
movement is possible. The holding fitting 7 that attaches the thermistor 8 to the fitting 6 can be removed from the fitting 6 together with the thermistor 8 by removing the screw 10 to the fitting 6. The screw 10 is mounted forward through the leg of the main body 1 through a gap on the bottom side so that it can be removed and installed by operating from the front.

In the air conditioner having the above configuration, when the installation location is specified, if the initial position of thermistor 8 is inappropriate for detecting room temperature, or there is a location more suitable for detecting room temperature nearby, If the problem cannot be solved by moving the position of the holding fitting 7, remove the screw 10 of the holding fitting 7, removing the thermistor 8 together with the holding fitting 7, and replacing the thermistor 8 with the holding fitting 7 at a position appropriate for detecting the room temperature. As a result, even if the initial position of the thermistor 8 becomes inappropriate due to the circumstances of the installation location, the thermistor 8 can be reattached to the most convenient position for detecting the room temperature within the range where the lead wire 10 extends, and the correct temperature can be detected. Appropriate driving will be done based on information.

Effects of the Invention As is clear from the above description of the embodiments, the room temperature detection element can be installed at the most suitable position within a predetermined range depending on the installation location, and an appropriate room temperature can be detected at the optimal position of the installation location. As a result, appropriate operation using appropriate temperature information can be realized.
