[0029] The utility model provides a water receiving tray 100 , which can completely drain water from the water receiving tray by moving a water scraper 20 in a water receiving groove 11 .
[0030] See Figures 1-4 The water receiving tray 100 includes a tray body 10 and a wiper 20. A water receiving groove 11 is provided on the tray body 10, and a water outlet is provided at least at one end of the water receiving groove 11 in the longitudinal direction. The wiper 20 is arranged in the water receiving groove 11 and can move along the longitudinal direction of the water receiving groove 11. The wiper 20 abuts against the bottom of the water receiving groove 11; wherein, a guide groove 14 is provided on at least one side wall of the water receiving groove 11 in the width direction, and the guide groove 14 extends along the longitudinal direction of the tray body 10, and a guide block 211 is protruded on the side of the wiper 20 close to the guide groove 14, and the guide block 211 extends into the guide groove 14 accordingly and slides against the groove wall of the guide groove 14.
[0031] Thus, the water receiving trough 11 is used to carry condensed water, and the outlet provided on the water receiving trough 11 allows the condensed water to flow out of the tray 10. The movement of the wiper blade 20 within the water receiving trough 11 pushes the condensed water onto the wiper blade 20 and out of the tray 10, thus preventing condensed water from remaining. The guide groove 14 cooperates with the guide block 211 on the wiper blade 20 to guide the movement of the guide block 211, making the movement of the wiper blade 20 more stable.
[0032] Furthermore, guide grooves 14 are formed on both sides of the water receiving groove 11 in the width direction, and guide blocks 211 are protruding from both sides of the wiper blade 20 in the width direction. The two guide blocks 211 are slidably connected to the two guide grooves 14 respectively. In this way, both sides of the wiper blade 20 in the width direction are restricted by the guide grooves 14, thereby further improving the stability of the movement of the wiper blade 20.
[0033] The wiper 20 includes a guide section 21 and a clamping section 22. The guide blocks 211 are arranged on both sides of the guide section 21 along its length direction. The clamping section 22 is connected to the guide section 21, and the thickness of the clamping section 22 gradually decreases along the depth direction from the groove mouth of the water receiving trough 11 to the groove bottom of the water receiving trough 11. The clamping section 22 abuts against the groove bottom of the water receiving trough 11.
[0034] In this way, since the wiper 20 will abut and rub against the side walls and bottom walls of the water receiving trough 11 during movement, the clamping section 22 gradually shrinks along the depth direction, that is, the upper end of the clamping section 22 connected to the guide section 21 (defined as the direction away from the bottom wall of the water receiving trough 11 as the upper side) is thicker, and the lower end where there is friction with the bottom wall of the water receiving trough 11 is thinner, which can not only ensure the connection strength between the clamping section 22 and the guide section 21, but also reduce the contact area between the clamping section 22 used for wiping and the wall of the water receiving trough 11, so as to reduce the resistance that the wiper 20 needs to overcome when moving.
[0035] Furthermore, the two sides of the clamping section 22 along its length are loosely fitted with the walls of the water receiving trough 11. This can further reduce the friction between the clamping section 22 and the walls of the water receiving trough 11 (due to the inevitable contact during movement, occasional contact friction between the clamping section 22 and the water receiving trough 11 will still occur), and reduce the noise generated by friction.
[0036] Along the depth direction, the height of the clamping section 22 is h, and the depth of the water receiving trough 11 is H, satisfying the following: 0.75H≤h≤0.9H. This ensures that the height of the clamping section 22 is sufficient to achieve a sufficient wiping effect, while preventing the wiper blade 20 from scratching the structure above the water receiving tray, such as the fins, if the clamping section 22 is too high.
[0037] The water receiving tray 100 further includes a motor 30, which is electrically connected to the wiper 20 and can drive the wiper 20 to move. In this way, the wiper 20 can be driven to move by the motor 30, which saves manpower and is convenient for automation.
[0038] Furthermore, the water tray 100 includes a sensor 40 electrically connected to the motor 30. The sensor 40 is connected to the wiper 20 and is spaced a first predetermined distance from the bottom of the water receiving trough 11. The first predetermined distance is set in advance and represents the liquid level at which the wiper 20 must operate to remove condensed water. When excessive condensed water accumulates and triggers the sensor 40, the sensor 40 activates the motor 30 through an electrical signal, thereby driving the wiper 20 to move.
[0039] Specifically, the sensor 40 is configured as a liquid level sensor 40 to detect the height of the condensed liquid level.
[0040] It can be understood that in other embodiments, the sensor 40 can also be arranged on the side wall of the water receiving groove 11, and an avoidance groove is opened on the wiper 20. When the wiper 20 moves laterally, the position of the avoidance groove corresponds to the sensor 40, thereby preventing the wiper 20 from interfering with the sensor 40.
[0041] Specifically, the wiper blade 20 is configured to reciprocate along the length of the water receiving trough 11 for 3-5 minutes after being triggered by the sensor 40 to ensure that the condensed water is completely discharged.
[0042] A first water outlet 12 and a second water outlet 13 are provided at both ends of the water receiving trough 11 in the longitudinal direction. The first water outlet 12 is provided on the side wall of the water receiving trough 11, and the second water outlet 13 is provided on the bottom wall of the water receiving trough 11. The first water outlet 12 is provided closer to the opening of the water receiving trough 11 than the second water outlet 13. The first water outlet 12 is connected to the second water outlet 13 via an external first water outlet pipe 50. As a result, the first water outlet 12 is located higher than the second water outlet 13, resulting in a higher pressure at the first water outlet 12 and a lower pressure at the second water outlet 13. This creates a siphon effect, allowing condensed water to flow from a higher pressure area to a lower pressure area, facilitating the discharge of the condensed water.
[0043] See Figure 5 The water receiving tray 100 further includes a second water outlet pipe 60, which is connected to the second water outlet 13. One end of the first water outlet pipe 50 is connected to the first water outlet 12, and the other end of the first water outlet pipe 50 extends toward and is connected to the second water outlet pipe 60. In this way, the first water outlet pipe 50 and the second water outlet pipe 60 are combined to discharge water, reducing the number of pipes and simplifying the structure.
[0044] The present invention also provides a fan coil unit, comprising the water receiving tray 100 as described above.
[0045] Compared to the prior art, the present invention incorporates a wiper blade 20 within the water receiving tray 100. The reciprocating motion of the wiper blade 20 completely drains condensed water from the water receiving groove 11 of the tray body 10, preventing the accumulation of condensed water and the generation of odor-causing bacteria, thereby extending the service life of the tray body 10. Guide blocks 211 are provided on both sides of the wiper blade 20 to engage with the guide grooves 14 on the tray body 10 to ensure the stability of the wiper blade 20. A motor 30 and a sensor 40 are also provided to detect the condensed water level, thereby enabling automated operation of the wiper blade 20.
[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
