Definitions

  • Patent Document 1 As a method for confirming drainage from the drain pipe, a method by visual inspection of the operator, a method by detecting the water level of the drain pan, and the passage of water in the drain pipe are detected. There is a way to do it. Further, as disclosed in Patent Document 2, there is a method based on detection of the discharge pressure and the rotational speed of the drain pump.
  • the subject of the present invention is that in an air conditioner equipped with a drain pan and a drain pump, it is possible to prevent an increase in the number of sensors necessary for confirming drainage during the trial operation of the drain pump, and from the drain pipe by the drain pump. The purpose of this is to make sure that the drainage can be fully confirmed.
  • the water can be sucked from the suction port of the pump body from the time when the drain pipe is filled until the pump head reaches the pipe head. Focusing on fluctuations in the current value up to the point where water is no longer discharged after reaching the incapable state, the drainage confirmation judgment is made.
  • the condition of “exceeding the first current set value when the first time has passed” as an appropriate drainage condition is that the water is filled in the drain pipe until the pump head reaches the pipe head. This means that it is determined whether the drainage flow rate from the drain pipe exceeds the current value that can sufficiently ensure the drainage flow from the pump body to the state before the pump body suction suction is reached. I'm going.
  • a drain pan 7 for receiving drain water generated in the heat exchanger 6 is disposed below the heat exchanger 6.
  • the drain pan 7 is attached to the lower part of the casing 2a.
  • the drain pan 7 has a suction hole 71 formed so as to communicate with the suction port 31 of the decorative panel 3, a blowout hole 72 formed so as to correspond to the blower outlet 32 of the decorative panel 3, and a bottom of the heat exchanger 6. And a drain receiving groove 73 formed on the side for receiving drain water. Further, a bell mouth 5 for guiding the air sucked from the suction port 31 to the impeller 41 of the blower 4 is disposed in the suction hole 71 of the drain pan 7.
  • step S7 based on the fluctuation in the current value of DC motor 82 during the trial operation of drain pump 8 obtained in step S6, it is determined whether the amount of water supplied to drain pan 7 is insufficient. Determine the amount of water to be used. The amount of water supply is determined by the drain pan before the pump head reaches the pipe head H, as shown in the current characteristic L5, until the pump head reaches the pipe head H from the start of the drain pump 8 trial operation. Exceeds the current value in the state where the water supplied to the pump is exhausted and air is sucked in from the suction port 81a of the pump body 81 (that is, water cannot be sucked from the suction port 81a of the pump body 81). It is determined whether or not.
  • step S3 the worker who has seen the error code corresponding to this water supply abnormality knows that the drain pump 8 has been trial run in a state where the amount of water supplied to the drain pan 7 is insufficient, and promptly supplies water to the drain pan 7. Action can be taken (ie step S3). On the other hand, if the appropriate amount of water supply is satisfied in the water supply amount determination, it is assumed that the water supply to the drain pan 7 is being properly performed, and the process proceeds to step S8.
  • this air conditioner 1 based on the fluctuation of the current value of the DC motor 82 that drives the pump body 81, more specifically, the water Since the volume is determined, it is possible to accurately check whether the amount of water supplied to the drain pan 7 is insufficient.
  • the pump 81 is in operation to suck air from the suction port 81a (that is, the suction port of the pump body 81).
  • 81 a to determine whether the current value is such that water cannot be sucked in from a). More specifically, the drainage confirmation determination is to determine whether or not the current value data of the DC motor 82 obtained in step S6 satisfies the proper drainage condition.
  • the proper drainage condition is that, as described above, of the fluctuation of the current value during the trial operation of the drain pump 8, the pump body 81 starts when the water fills the drain pipe 9 until the pump head reaches the pipe head H.
  • the appropriate drainage condition is that the drain pipe by the drain pump 8 is used from the viewpoint of whether the relationship between the pump head and the pipe head H is appropriate, and whether the drainage flow from the drain pipe 9 is appropriate. It means the condition for judging whether drainage from 9 is properly done.
  • This drainage confirmation determination is performed by the control unit 24 of the electrical component unit 21 that functions as a drainage confirmation determination unit.
  • the drainage flow rate and drainage time are insufficient. If the drain pipe 9 is clogged (i.e., current characteristic L4), or if the water does not fill the drain pipe 9 until the pump head reaches the pipe head H (i.e., current characteristic L3) If the proper drainage conditions are not met, the drainage from the drain pipe 9 is not properly drained and the process proceeds to step S10 where the control unit 24 of the electrical component unit 21 that also functions as an abnormal signal output means 24 As a result, drainage from the drain pipe 9 by the drain pump 8 is properly performed, and a drainage abnormality signal indicating that the drainage control is output to the remote controller 26.

Abstract

Dans un conditionneur d'air comportant un bac de vidange et une pompe de vidange, pendant un essai de fonctionnement de la pompe de vidange, il est possible de contrôler suffisamment la vidange de l'eau provenant de la conduite de vidange tout en supprimant l'accroissement du nombre de détecteurs requis pour contrôler la vidange de l'eau. Le conditionneur d'air (1) inclut un bac de vidange (7) et une pompe de vidange (8) pour vidanger l'eau accumulée dans le bac de vidange (7) par l'intermédiaire d'une conduite de vidange (9). La pompe de vidange (8) inclut un corps de pompe (81) branché sur la conduite de vidange (9) et un moteur à courant continu (82) qui entraîne le corps de pompe (81). Selon la fluctuation de la valeur du courant du moteur à courant continu (82) pendant un essai de fonctionnement de la pompe de vidange (8), le conditionneur d'air (1) effectue une vérification de la vidange de l'eau pour contrôler si la vidange de l'eau à partir de la conduite de vidange (9) par la pompe de vidange (8) est effectuée correctement.
