Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sensor fixing device for an air conditioner.

Conventional configuration and its problems Conventionally, as shown in Fig. 5, evaporator 1 and evaporator 1
When there is not enough space between the air filter on the front of the evaporator to easily incorporate the thermistor 3 that detects the room temperature, or when there is not enough space between the evaporator 1 and the casing, as shown in Figure 6. A sensor fastener 5 like this was used. 6 is evaporator 1
7 is a clamping part that clamps the copper pipe 7a, 8 is a lead wire 9 of the thermistor 3.
It is a support part that holds the When the sensor stopper 5 is installed in an air conditioner, the upper fin of the evaporator 1 is folded down, a space 10 having a gap a is provided, the holding part 8 is housed, and when the sensor 3 is attached, the upper fin of the evaporator 1 is folded down. After the evaporator fin is folded down, there is a space 10 large enough to prevent the sensor 3 from touching the fin.
is formed. Reference numeral 11 denotes a top plate that supports the shafts of cross flow fans 12 and 13, partitions them from air guider 14, and forms a ventilation path. Reference numeral 15 denotes a constriction section in which the sensor stopper 5 and the sensor 3 are mounted in the space 10, and the top plate 11 is formed into a convex shape so that the air passing through the space 10 flows smoothly without resistance.

When fixing the sensor fixture 5 to the evaporator 1 in the sensor fixing structure as described above, before assembling the top plate 11, the upper fins of the evaporator 1 are folded down to create a space 10, and the sensor fixture 5 is attached from the leeward side. However, with this structure, when tilting the fins, it is necessary to perform positioning using a jig or the like, which takes a lot of man-hours, and when the sensor stopper 5 is to be removed during service, it is necessary to remove the top plate 11, which takes time. It takes. Furthermore, since the air passing through the space 10 and the constriction section 15 is not cooled and dehumidified by the evaporator 1, it mixes with the cooled and dehumidified air that passes through the evaporator 1, and is cooled. The dehumidification caused condensation on the cross flow fan 12 and the like, and the condensed water was blown away from the air outlet 16 to the indoor side, causing problems.

Purpose of the invention The purpose of this invention is to eliminate the drawbacks found in the sensor fixing structure of the conventional air conditioner, and to prevent dew condensation on the cross flow fan, etc., and to provide a thin air conditioner. That is.

Structure of the Invention In order to achieve this object, the present invention provides a fin cut on the windward side of the evaporator to form a groove, and integrally provides a roof portion formed similar to the groove.
Furthermore, a sensor stopper is fixed to the corner of the roof portion, which has a C-cut portion for guiding the air filter toward the grille. This configuration prevents dew condensation on other parts and the blowing of condensed water toward the indoor side.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to FIGS. 1 to 4 of the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 4 denotes a casing of an air conditioner, and a front grill 17 is attached to the front of the air conditioner.
It has 9. Reference numeral 20 denotes a control unit that controls various operations of the air conditioner, and various electrical components (not shown) are incorporated therein. Reference numeral 1 denotes an evaporator provided opposite the suction port 18, and a filter 2 is provided between the suction port 18 and the evaporator 1 to remove dust and the like from the air. A groove portion 20 is formed by cutting out a fin on the windward side of the evaporator 1. 21 is a sensor stopper, 6 is a clamping part that clamps the copper pipe 22 of the evaporator 1, 7 is a clamping part that is clamped between the copper pipes 22 and 23,
It is formed to be thick enough to be easily inserted between the fin pitches of the evaporator 1. Reference numeral 8 denotes a support portion that holds the lead wire 9 of the thermistor 3, and a roof portion 24 is formed in the upper part of the back side of the support portion 8 in the horizontal direction so as to cover the sensor 3 and the lead wire 9. The roof portion 24
This prevents the connecting water connected in the evaporator 1 from dripping onto the sensor 3 and the lead wire 9, being rapidly cooled, and causing malfunction. Furthermore, a reinforcing surface 25 for supporting the clamping parts 6 and 7 is formed on the rear side and downward side of the clamping part 8. The roof portion 24 and the reinforcing surface 2
5 is formed continuously and integrally, and its shape is similar to the shape of the evaporator groove 20. Further, the width b of the reinforcing surface 25 is equal to the width b of the roof portion 24.
The width c is smaller than the width c of the sensor 3, and an escape portion 26 is provided so that the flow of air passing through the sensor 3 is not obstructed, thereby improving the sensitivity of the sensor. 27,2
Reference numeral 8 denotes a C-cut portion provided at the corner of the portion of the roof portion 24 that protrudes from the groove portion 20 of the evaporator 1. When the handle 29 of the air filter 2 is slid in the left-right direction to be attached or removed, the filter 2 is attached to the sensor stopper. This prevents it from getting caught on the roof 24 or the fins of the evaporator 1.

In the above configuration, when the sensor stopper 21 is assembled into the evaporator 1, the clamping parts 6 and 7 are inserted between the evaporator fins at approximately left and right positions of the groove part 20, and are fitted and fixed into the copper pipes 22 and 23. Therefore, it can be easily assembled even after the top plate 11 has been assembled, and the sensor stopper 21 can be easily removed by simply removing the grille 17, and a jig for positioning is not required. can be assembled into.

Effects of the Invention As is clear from the above embodiments, the air conditioner sensor fixing device of the present invention has a groove in the evaporator, and a sensor stopper with a C-cut in the corner of the roof is attached to the groove in the groove. Therefore, even if there is not enough clearance between the evaporator and the air filter,
Since the air filter is guided toward the grill side by the C-cut, the filter can be easily attached and detached without getting caught on the fins of the evaporator, and it is necessary to provide a sufficient gap between the evaporator and the air filter. This makes it possible to make the air conditioner thinner, and since the evaporator and air filter do not come into contact with each other, condensed water that condenses in the evaporator adheres to the air filter and accumulates on the air filter, reducing air volume. Nothing. Furthermore, as in the past,
It is possible to eliminate air bypassing the evaporator, prevent condensation on cross flow fans, etc. Furthermore, there is no need to fold down the fins, reducing assembly man-hours, allowing for inexpensive assembly. It also has various advantages, such as being able to reliably detect the temperature without causing malfunctions due to dripping of condensed water or the like.
