Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a temperature control switch used in air conditioners for cooling and heating.

[Conventional technology]

BACKGROUND ART In air conditioners for heating and cooling, a temperature control switch is provided to sense the indoor temperature and turn on or off cooling or heating operation to maintain the indoor temperature at a set temperature. This temperature control switch is also integrated with a switching switch between heating and cooling, and is provided as a temperature regulator with a heating/cooling switching switch.

Such a temperature regulator is provided with an operating circuit and the like inside a base that is attached to a wall surface, etc., and is provided with a temperature sensing part and an operation part for setting the temperature on the outside. However, if the temperature sensing part is exposed, it may be damaged or measurement errors may occur if it is touched by fingers or the like.
Therefore, a cover is installed to keep the temperature sensing part in communication with the indoor air.

On the other hand, if the heating/cooling switch is installed externally, there is a high risk of erroneous operation. Therefore, this changeover switch is not exposed to the outside, but is placed in a position where it is covered by a cover such as the temperature-sensing section, so that the switch must be operated after removing the cover.

[The problem that the idea aims to solve]

However, such a structure places too much emphasis on preventing erroneous operations, making it difficult to perform cooling/heating switching operations.

The present invention has been made in view of the above facts, and an object of the present invention is to provide a temperature regulator with a cooling/heating changeover switch that is easy to operate and less prone to erroneous operation.

[Means to solve the problem]

In order to achieve the above object, the temperature regulator with a cooling/heating switch of the present invention has a base having a mounting surface to a wall surface etc., a temperature sensing part and a temperature setting part protruding from the base, and a temperature sensing part and a temperature setting part protruding from the base. a sliding type cover having a reciprocating direction substantially parallel to the mounting surface and protruding from the base at a position facing the cover; It consists of a knob for a cooling/heating changeover switch, and a switch lever that is removably fitted and moved together with the knob, has a sliding direction in the length direction, and can alternately protrude from the cover at both ends.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of the temperature regulator with a cooling/heating switch of the present invention with the cover removed, and FIG. 2 is a side view.

First, the configuration will be explained. In these figures 1
2 is a base, 2 is a cover, 3 is a temperature setting part, 4 is a temperature sensing part, 5 is a knob for a cooling/heating switch, 6 is a switch lever, and 7 is a gap between the base 1 and the cover 2. The base 1 has a mounting surface 1a that is attached to a wall surface, etc.
Although not shown, an operating section consisting of an electronic circuit and the like is housed inside. The cover 2 is fitted into the frame 8 and secured to the base 1 by a stopper 9 shaped like a leaf spring. The frame 8 is fastened to three pillars 10 erected on the base 1 with screws 11. The base 1 includes a shaft 12 having a female thread formed in the center and the shaft 12.
A male threaded shaft 13 is provided upright to be screwed together. The male threaded shaft 13 is supported with its tip passing through the frame 8, and a disk 3 serving as a temperature setting section is fixed to the tip. A temperature sensing section 4 is fixed to the shaft 12. The temperature sensing section 4 is formed by laminating two diaphragms with their convex surfaces facing outward and leaving a space inside. The thickness of the temperature-sensing section 4 changes as the gas sealed in the space expands or contracts due to changes in temperature. The position of the end of the temperature sensing part 4 on the base 1 side is detected by the operating part to start and stop the air conditioner. A temperature scale is engraved on the disc 3 that serves as the temperature setting section, and by rotating the part that protrudes from the cover 2, align the triangular mark drawn on the frame 8 with the number on this temperature scale to set the desired temperature. Set the temperature to
With the above configuration, the air conditioner is operated and stopped according to the set temperature.

A gap 7 is provided between the base 1 and the cover 2 to allow the temperature sensing part 4 to come into contact with the indoor air.

The switch knob 5 is a knob of a heating/cooling switch provided in an electronic circuit in the base 1, and moves substantially parallel to the mounting surface 1a to switch between cooling and heating.

The switch lever 6 is made of resin such as polycarbonate, has a shape as shown in FIGS. 3a and 3b, and has a hole 6a for fitting into the switch knob 5. The switch lever 6 is removably fitted to the switch knob 5 and is housed in the gap 7 between the cover 2 and the base 1. Note that there are several protrusions 6 in the fitting hole 6a.
b is formed to prevent wobbling after fitting.

The switch lever 6 slides substantially parallel to the mounting surface 1a and in the length direction to move the switch knob 5 to switch between cooling and heating. The solid line in FIG. 1 indicates the stop position on one side of the switch lever 6, and the two-dot chain line indicates the stop position on the other side. switch lever 6
At least one end always protrudes from the cover 2 of the temperature controller, with the upper end protruding when the solid line is drawn and the lower end protruding when the double-dashed line is drawn. Therefore, without removing the cover 2, switching between cooling and heating can be performed by pushing up and down the switch lever 6. Moreover, as shown in FIG. 1, heating is shown at both ends. If you display "HEAT" and "COOL" indicating cooling,
It not only displays the current situation but also prevents erroneous operations. The switch lever 6 of the embodiment of the present invention is detachable, and if removed, it has the conventional function of preventing erroneous operation.

[Effect of idea]

As explained above, according to the present invention, the switch lever 6 slides along the mounting surface such as a wall surface, and one of the ends always projects outward.
The switching operation between cooling and heating can be easily performed without removing the cover 2. Moreover, since most of it is covered by the cover 2, there is little possibility that fingers or the like will accidentally touch it. Therefore, prevention of erroneous operation and ease of operation are appropriately balanced, and a temperature regulator with a cooling/heating changeover switch that satisfies both purposes can be obtained.
