Description

  The present invention relates to an auxiliary pipe presser for a room conditioner having an auxiliary pipe.

  Conventionally, auxiliary piping pressers for this type of room air conditioner are fixed to the frame hole of the frame by the left and right fixing claws of the auxiliary piping presser. A simple jig is inserted, and the fixing claw is pressed and removed from the frame hole, and then removed from the frame.

  Further, in order to facilitate the removal, there is an auxiliary pipe presser hooking part base frame side provided with an inclined part, and an auxiliary pipe presser claw is also provided with an inclined part (see, for example, Patent Document 1).

FIG. 7 shows a top view of an auxiliary piping presser of a conventional air conditioner described in Patent Document 1. As shown in FIG. FIG. 8 shows a plan view of the main part of an auxiliary piping presser provided with an inclined portion at the pawl. As shown in FIG. 8, the auxiliary pipe presser 1 is fixed to the frame hole 4 of the frame 2 by a fixing claw 3.
Japanese Patent Laid-Open No. 11-159797

  However, in the conventional configuration, when the claw and the frame hole of the auxiliary piping presser are fixed, the claw cannot cover the frame hole and the outside air may enter from the gap. When outside air enters through the gap in the underframe hole, the heat exchanged cold air flows inside the underframe, so the surface of the underframe is cooled, and condensation water may be generated due to condensation of the outside air that has entered. Had the problem of being.

  The present invention solves the above-described conventional problems, and prevents the generation of condensed water due to the entry of outside air from the fitting part of the auxiliary piping presser and the fitting part of the frame hole, and the room air that can be easily removed. It aims at providing the auxiliary piping presser of a harmony machine.

  In order to solve the above-described conventional problems, the auxiliary piping presser according to the present invention is provided with a step at the center of the pawl.

  As a result, when the auxiliary pipe presser and the frame hole are fixed, it is possible to completely close the gap of the fitting portion and facilitate removal of the auxiliary pipe presser.

  The auxiliary piping presser of the present invention can reduce condensation within the underframe and prevent problems such as water leakage and water splash from the air conditioner. Further, the removal becomes easy, and the serviceability can be improved.

According to the first aspect of the present invention, the step of the auxiliary piping presser is provided with a step structure, so that when the auxiliary piping presser and the frame hole are fixed, the gap of the fitting portion is closed, and the minus driver is further attached to the frame and the auxiliary frame. Since it can be inserted through a gap having a level difference between the pipe presser tabs, the auxiliary pipe presser can be easily removed.

  In the second invention, in particular, by providing an inclination angle to the step structure of the first invention, it is possible to reduce the force when inserting a flathead screwdriver and holding the pawl, and it is easier to use the auxiliary pipe presser. Can be removed.

  The third invention, in particular, by providing ribs at both ends of the step structure of the first or second invention, serves as a stopper to prevent slipping of the minus driver when inserting the minus driver and holding the pawl. The force when pressing the pawl can be reduced, and the auxiliary piping presser can be removed more easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a development view of a frame and an auxiliary piping presser of the air conditioner according to the first embodiment of the present invention, and FIG. 2 is a frame of the auxiliary piping presser according to the first exemplary embodiment of the present invention. The rear view of the state attached to is shown.

  1 and 2, in order to fix an auxiliary pipe (not shown) extending from the rear surface of the indoor unit frame 2 of the air conditioner to the frame 2, the auxiliary pipe presser 1 sandwiches the auxiliary pipe. It has a pawl 3 for extending and locking to the underframe. The auxiliary piping presser 1 is attached from the back surface of the frame 2 and is fixed to the frame 2 with four claws. Among the pawls of the auxiliary pipe presser 1, the pawl 3 in the figure is fitted into the frame hole 4 and fixed.

  3 is a perspective view of the auxiliary piping presser according to the first embodiment of the present invention, and FIG. 4 is a top view of the auxiliary piping presser of FIG.

  3 and 4, a stepped portion 6 is formed in the central portion of the pawl 3 that engages with the frame hole 4. By this step portion 6, the pawl 3 of the auxiliary pipe presser 1 has a structure in which the frame hole 4 is completely closed. Furthermore, when removing the auxiliary piping presser 1 from the frame 2, insert a flathead screwdriver into the gap between the step 6 and the frame 2 of the auxiliary piping in FIG. It can be removed from the frame hole 4 and easily removed.

  As described above, in this embodiment, by forming a step portion at the center portion of the claw to be fitted with the frame hole, the auxiliary pipe presser is removed from the frame while having a structure for sealing the frame hole. And serviceability can be improved.

(Embodiment 2)
FIG. 5 shows a top view of the auxiliary piping presser according to the second embodiment of the present invention.

  In FIG. 5, by providing an inclined angle 7 in the step portion 6 of the pawl 3 of the auxiliary pipe presser 1, the pawl 3 of the auxiliary pipe presser 1 maintains a structure in which the frame hole 4 is completely closed, At the time of removal, when a flathead screwdriver is inserted and the pawl 3 is pressed, it is easy to apply a force in a direction to remove the pawl 3 from the frame hole 4, so that the removal becomes easier. Thereby, the auxiliary piping presser 1 can be removed more smoothly from the base frame 2, and the serviceability can be further improved.

As described above, in the present embodiment, the auxiliary pipe presser is removed from the base frame while maintaining the structure for sealing the base hole by providing an inclined angle at the step portion of the pawl of the auxiliary pipe presser. It becomes easier and serviceability can be improved.

(Embodiment 3)
FIG. 6 shows a perspective view of an auxiliary piping presser according to the third embodiment of the present invention.

  In FIG. 6, the ribs 8 are provided at both ends of the step portion 6 of the pawl 3 of the auxiliary pipe presser 1, so that the pawl 3 of the auxiliary pipe presser 1 maintains a structure in which the frame hole 4 is completely closed. In the case of removal, since the slide of the minus driver can be received by the rib 8 when the minus driver is inserted and the pawl 3 is pressed, the removal becomes easier. Thereby, an auxiliary piping presser can be removed from a frame more smoothly, and the further improvement in service property is attained.

  As described above, in the present embodiment, the ribs are provided at both ends of the stepped portion of the auxiliary pipe presser so that the auxiliary pipe presser can be removed from the base frame while maintaining the structure for sealing the frame hole. Since the jig is fixed at the time of removal, the auxiliary piping presser can be removed from the frame more smoothly, and serviceability can be further improved.

  As described above, the auxiliary piping presser of the room air conditioner according to the present invention facilitates the removal of the claw portion to be engaged with the base frame, and thus various types of components that are engaged with the two components by the claw. Applicable to structure.
