Abstract
(EN)
Provided are a water pump component, an outdoor unit, and a control method for an outdoor unit. The water pump component comprises: a water pump (1) having a water inlet (7), a second heating element (4) being provided at the water inlet (7); a first heating element (3) heating a water drainage pipe (2) of the water pump (1); and a third heating element (6) on a base plate. The first heating element (3) is used to heat the water drainage pipe (2), thereby preventing condensate in the water drainage (2) from freezing, and guaranteeing water drainage efficiency. The second heating element (4) is used to heat condensate within the water pump component, thereby preventing an interior thereof from freezing and causing damage to the water pump component. The third heating element (6) is used to ensure that condensate on the base plate will not freeze, and can smoothly flow to the water pump component, such that reliable drainage of a machine can be achieved when an ambient temperature is 0℃ or below, improving the reliability of the machine under very low ambient temperatures.

L'invention concerne un composant pompe à eau, une unité extérieure et un procédé de commande pour une unité extérieure. Le composant pompe à eau comprend : une pompe à eau (1) ayant une entrée d'eau (7), un second élément chauffant (4) qui est disposé au niveau de l'entrée d'eau (7); un premier élément chauffant (3) qui chauffe un tuyau de drainage d'eau (2) de la pompe à eau (1); et un troisième élément chauffant (6) placé sur une plaque de base. Le premier élément chauffant (3) est utilisé pour chauffer le tuyau de drainage d'eau (2), empêchant ainsi la condensation présente dans le drainage d'eau (2) de geler, et garantissant une efficacité du drainage d'eau. Le second élément chauffant (4) est utilisé pour chauffer la condensation à l'intérieur du composant pompe à eau, empêchant ainsi l'intérieur de celui-ci de geler et d'endommager le composant pompe à eau. Le troisième élément chauffant (6) est utilisé pour assurer que la condensation sur la plaque de base ne gèle pas, et peut s'écouler sans à-coups vers le composant pompe à eau, de telle sorte qu'un drainage fiable d'une machine peut être obtenu lorsqu'une température ambiante est de 0 °C ou moins, ce qui permet d'améliorer la fiabilité de la machine à des températures ambiantes très basses.
