Definitions

  • the invention relates to an air conditioner, in particular an indoor air conditioner with a detachable housing.
  • An air conditioner is a temperature regulating and maintaining piece of equipment typically installed in indoor locations such as rooms and other spaces inside a building to provide cool air and to maintain the temperature inside the indoor locations at a preset level.
  • the current indoor air conditioners on the market include single body-type devices in which all the components are arranged within a housing, and separate or split type devices in which some of the components are provided within an indoor unit and the remaining components are provided within an outdoor unit of the air conditioner.
  • the split type indoor air conditioners further include a wall hanging type device, a ceiling suspended device or a stand type device, of which the wall-hanging type indoor air conditioners, which are typically attached to the wall of rooms or other indoor spaces, are the most common type of split type indoor conditioner.
  • the indoor unit of the split type air conditioner typically includes a rear body with a back plate that can be attached to a wall surface to hold the heat exchanger and other components within the body for discharging cool air and removing hot air from the indoor space.
  • the outdoor unit includes a compressor, an outdoor heat exchanger and expansion device and the like to heat exchange air. Periodic and proper cleaning and maintenance of the indoor and outdoor units of the split type air conditioner is necessary for proper operation, improved life span and optimal efficiency of the air conditioner.
  • Typical wall-hanging type air conditioners are installed on the walls of rooms or other spaces near the ceiling for proper distribution of cool air and optimal air circulation within the space.
  • the rear body of the wall hanging type indoor air conditioner includes all the components for receiving air through an air inlet and discharging cool air through an air outlet.
  • a housing having grills or openings at the air inlet and outlet is used to enclose the rear body, which further improves the aesthetics of the air conditioner and protects the components from dust and accidental damage.
  • the housing of a wall hanging type air conditioners is typically hinged to the rear body to allow it to be swung open to access the components for cleaning and maintenance.
  • the housing is connected to the rear body at a top portion using one or more hooks, which allow swing opening to access the components inside the rear body.
  • the air conditioner is attached to the wall and positioned near the ceiling, then there is insufficient space for complete swing opening of the housing to access the air conditioner components.
  • Removing the housing requires a user to access the hooks through a small gap between the ceiling and the top portion of the housing. In some instances, the users may find it difficult to identify the position of the hooks on the top portion of the housing as the hooks are not easily visible from a front side of the air conditioner.
  • the hooks may be disengaged by lifting the housing from the body, which requires more space between the ceiling and the top portion of the housing. Hence, it is difficult to detach the hook connecting the rear body and the housing of the typical wall hanging type air conditioner when installed on the wall near the ceiling.
  • An aim of the invention therefore is to provide an indoor air conditioner which overcomes the above issues.
  • an air conditioner comprising: a body including a plurality of components for heat exchanging air; a housing for substantially enclosing the front of the body and comprising a plurality of openings for passage of the air; characterized in that a plurality of sliding catches is provided on a top portion of the housing for detachable engagement with a plurality of slots provided on the body, the plurality of sliding catches being adjustable between a locked position and an unlocked position to respectively secure or allow removal of the housing from the body.
  • the air conditioner can be installed on the wall near the ceiling, wherein the housing can be secured to the body by adjusting the sliding catches to a locked position and easily removed by moving the sliding catches to an unlocked position. This helps in the easy cleaning and maintenance of the indoor air conditioner components inside the body.
  • the housing may be secured to the body with screws in addition to the catches, to prevent accidental detachment of the housing.
  • a first sliding catch is provided at one end of the top portion of the housing and a second sliding catch is provided at the other end of the top portion of the housing.
  • corresponding slots are provided at respective ends of the body.
  • a third sliding catch and corresponding slot is provided at a point in between the ends of the top portion of the housing.
  • the third sliding catch is provided at a centre point of the top portion.
  • each of the sliding catches comprises a head portion and a hook portion extending downwards from the head portion.
  • the hook portion is configured for detachable engagement with a corresponding slot, groove, recess or the like on the body.
  • this helps to easily secure the housing to the body.
  • each of the sliding catches protrudes from the top portion of the housing.
  • the housing is secured to the body by adjusting the sliding catches to the locked position.
  • the user can push the housing from the front side of the body to substantially enclose and thereafter secure the same to the body.
  • the housing secured to the body is removable by adjusting the sliding catches to the unlocked position and thereafter pulling the housing towards the front side of the body in a linear sliding motion.
  • this helps the user to easily access the indoor air conditioner components inside the body for cleaning and maintenance, even if installed on the wall surface near the ceiling, as the body pulls out horizontally rather than pivoting upwards where access may be limited due to the ceiling.
  • the air-conditioner is a wall hanging type indoor air-conditioner configured to attach to anywhere on the wall surface including positions near the ceiling.
  • Figure 1 illustrates an indoor air conditioner according to an embodiment of the invention in which a housing is removably secured to a body of an indoor air conditioner as shown in: (a) perspective view; (b) side view; (c) side view showing partially detached housing; (d) perspective view showing partially detached housing.
  • Figure 2 illustrates (a) perspective view of a sliding catch on the housing and a corresponding slot on the body of the indoor air conditioner; (b) sectional side view of Figure 2a according to the embodiment of the invention as shown in Figures 1 a-d.
  • Figure 3 illustrates an alternate perspective view of a sliding catch and the corresponding slot of the indoor air conditioner according to the embodiment of the invention as shown in Figures 1 a-d, in which the sliding catch is in: (a) locked position; (b) unlocked position.
  • the indoor air conditioner 10 comprises a body 12, a housing 14, a plurality of sliding catches 16 on a top portion 30 of the housing 14, a plurality of slots 18 on the body 12 for detachably engaging with the corresponding sliding catches 16 on the housing 14, a top grill 32 for passing air and an adjustable vane 34 for directing cool air.
  • the body 12 of the indoor air conditioner 10 comprises an upper portion 38, a lower portion 40, a pair of side portions 42 and a back portion 44.
  • the back portion 44 is configured to attach to a wall surface.
