In the related technology, the lower end of the heat exchanger 4 is directly contacted with the bottom of the water receiving tank 30, and airflow is difficult to enter the bottom of the water receiving tank 30 and exchanges heat through the heat exchanger 4, so that the heat exchange at the lower end of the heat exchanger 4 cannot be well utilized; moreover, when the water receiving tank 30 has condensed water, the lower end of the heat exchanger 4 is immersed in the condensed water, and a part of the heat exchanger 4 located in the condensed water cannot perform a good heat exchange function; in addition, the heat exchanger 4 may obstruct the flow of the condensed water, and the condensed water may be accumulated in the water receiving tank 30.

Therefore, in some embodiments of the ceiling machine, the support table 301 protrudes upwards from the bottom of the inner tank of the water receiving tank 30, the lower end of the heat exchanger 4 abuts against the support table 301, so that the lower end of the heat exchanger 4 is located in the water receiving tank 30 and is higher than the bottom of the water receiving tank 30, and when the water in the water receiving tank 30 is not higher than the support table 301, the heat exchanger 4 can be prevented from being soaked in the water receiving tank 30, so that the airflow can pass through the bottom end of the heat exchanger 4 more easily, and the heat exchanger 4 can be utilized more fully; moreover, the heat exchanger 4 no longer obstructs the flow of the condensed water in the water receiving tank 30.

One example of the position setting of the support table 301: the support platform 301 is set against the first tank sidewall 3001 of the water receiving tank 30, that is, the support platform 301 is regarded as the tank bottom of the water receiving tank 30, on the longitudinal section of the water receiving tank 30, the inner side of the tank bottom of the water receiving tank 30 is higher, the outer side is lower, and the bottom end of the heat exchanger 4 is abutted against the position of the higher tank bottom.

In the above embodiment, the supporting platform 301 can only be supported at the inner side of the bottom end of the heat exchanger 4, which may cause the problem of unbalanced and inclined force on the heat exchanger 4, and in this case, in order to ensure the stable support of the heat exchanger 4, the supporting platform 301 needs to be set wide enough, which inevitably occupies the space in the water receiving tank 30, resulting in the reduction of the capacity of the water receiving tank 30.

Thus, another embodiment of the position setting of the support table 301 is provided: the support platform 301 is arranged in the middle of the water receiving tank 30, on the longitudinal section of the water receiving tray 3, the support platform 301 divides the water receiving tank 30 into two parts, namely a first tank 302 and a second tank 303, wherein the first tank 302 is close to the inner side, and the second tank 303 is close to the outer side; with the setting of supporting bench 301 in the middle of water receiving tank 30, supporting bench 301 just can support the center of heat exchanger 4 for supporting bench 301 is more steady to the support of heat exchanger 4, and heat exchanger 4 can not produce the slope.

Specifically, the vertical center line of the heat exchanger 4 may intersect with the support table 301 on the longitudinal section of the water pan 3 when in the assembled position.

Based on the above embodiment, the first groove 302 is arranged to correspond to the windward side of the heat exchanger 4, so that the condensed water generated on the windward side of the heat exchanger 4 falls into the first groove 302, and the second groove 303 corresponds to the air outlet side of the heat exchanger 4, wherein the windward side refers to the side of the airflow flowing into the heat exchanger when the airflow passes through the heat exchanger 4 for heat exchange; the air outlet side refers to the side of the heat exchanger where the airflow flows out; the support platform 301 may be disposed near the second trough sidewall 3002 of the water receiving trough 30, that is, the width d1 of the first trough 302 is greater than the width d2 of the second trough 303; the capacity of the first tank 302 can be made larger by the combination of d1 > d2, so as to adapt to the condition that the windward side of the heat exchanger 4 generates relatively more condensate water.

In some embodiments of this smallpox machine, be provided with the sponge between the bottom of heat exchanger 4 and the upper surface of a supporting bench 301 to realize sealedly, prevent that the air current from passing from the gap between heat exchanger 4 and a supporting bench 301, and then influence heat exchange efficiency.

Specifically, the sponge may be attached to the upper surface of the support platform 301, and the support platform 301 and the water pan 3 may be integrally formed. In addition, the wall thickness of the supporting platform 301 is the same as that of the wall of the water receiving tank 30, so that the forming is convenient.

Based on the above embodiment, the relation between the width d3 of the support table 301 and the width d4 of the heat exchanger 4 is set to 0.25d4 ≦ d3 < d4, for example, the width d4 of the heat exchanger 4 is 40mm, and the width of the support table 301 can be selected to be 18mm, 20mm, 22mm, etc.; d3 that is not less than 0.25d4 can guarantee that the support platform 301 effectively supports the heat exchanger 4, can not make the heat exchanger 4 unstable because of too narrow, and can not influence the sealed effect of sponge because of too narrow, and d3 < d4 can guarantee the capacity of water receiving tank 30, can not occupy the space of water receiving tank 30 because of support platform 301 is too wide. Therefore, the relation between the width d3 of the support platform 301 and the width d4 of the heat exchanger 4 is set according to the relation that d3 < d4 is more than or equal to 0.25d4, so that the capacity of the water receiving tank 30 is maximized, and the stable support of the support platform 301 on the heat exchanger 4 and the sealing effect between the heat exchanger 4 and the support platform 301 can be ensured.

The relationship between the height h1 of the support platform 301 and the height h2 of the lowest point of the top surface of the water receiving tank 30 is: h1 is not more than 2/3h2, so that the heat exchanger 4 can be separated from the bottom of the water receiving tank 30, the bottom of the heat exchanger 4 is prevented from being soaked in the water receiving tank 30, the heat exchange efficiency of the heat exchanger 4 is further reduced, the condensed water on the heat exchanger 4 can flow into the water receiving tank 30, the condensed water generated on the surface of the heat exchanger 4 is guaranteed to be smoothly discharged outwards, and the length of a condensed water discharge path is reduced so as to improve the drainage efficiency.

Based on the above embodiment, referring to fig. 23-25, the extension of the support platform 301 corresponds to the lower end of the heat exchanger 4, and since the drain pump 8 is located at one corner of the water pan 3 and the drain pump 8 is located in the second tank 303, the condensed water in the first tank 302 is prevented from flowing to the drain pump 8 and being discharged due to the obstruction of the support platform 301.

Therefore, a plurality of gaps 304 are arranged on the support platform 301 at intervals, the bottom surface of each gap 304 is coplanar with the bottom surface of the water receiving tank 30, the first tank 302 and the second tank 303 can be communicated through the gaps 304, namely, condensed water can flow between the first tank 302 and the second tank 303 through the gaps 304, so that the situation that the support platform 301 blocks the condensed water in the first tank 302 to be discharged is avoided, the outflow of water flow in the water receiving tank 30 is facilitated, the gaps 304 are less in flowing air flow, and the heat exchange influence on the ceiling fan is less.

Specifically, the airflow in the ceiling fan is mainly discharged through the first exhaust port 32 located at the edge, the airflow flowing to the corner causes more air loss due to space limitation and blocking of the structure at the corner, and the airflow passing through the notch 304 cannot exchange heat through the heat exchanger 4, therefore, the notch 304 can be arranged corresponding to the corner part close to the water-receiving tray 3, so that even the air volume of the air flow passing through the notch 304 is lost at the corner part, the air flow is not subjected to heat exchange, the whole heat exchange efficiency and the air volume are not influenced, if the notch 304 is disposed corresponding to the edge, the air flowing through the notch 304 will be sent to the air outlet, and the air quantity lost at the corner part is still the air flow after heat exchange, therefore, the gap 304 of the ceiling machine is arranged at the corner part which is close to the water pan 3 correspondingly, and the ceiling machine has the advantages of high heat exchange efficiency and small air quantity loss after heat exchange.

Specifically, the length of the notch 304 may be set to 5mm to 20mm, which not only ensures the circulation between the first groove 302 and the second groove 303, but also prevents excessive air flow from flowing out of the notch 304, thereby avoiding the influence of the larger notch 304 on the heat exchange airflow efficiency.

Based on the above-mentioned embodiment, the notch 304 may be disposed on a straight line segment of the supporting platform 301 near the corner, so as to facilitate the machining of the notch 304.

Referring to fig. 20, two side walls of the water receiving tray 30 are respectively a first tank side wall 3001 located on the inner side and a second tank side wall 3002 located on the outer side, and due to the blocking of the first tank side wall 3001 and the second tank side wall 3002 in the water receiving tray 3 and the small gap between the lower end of the heat exchanger 4 and the water receiving tray 30, the air flow is still influenced to exchange heat through the lower end of the heat exchanger 4.

Therefore, in some embodiments of the ceiling fan, the first slot sidewall 3001 of the water receiving slot 30 is disposed obliquely from bottom to top toward the air inlet, and the second slot sidewall 3002 of the water receiving slot 30 is disposed obliquely from bottom to top toward the air outlet, that is, in the longitudinal section of the water receiving tray 3, the first slot sidewall 3001 and the second slot sidewall 3002 form an obtuse angle. The slope setting of first groove lateral wall 3001 of water receiving tank 30 can make things convenient for the air current to flow in water receiving tank 30 from the notch of water receiving tank 30 to make full use of heat exchanger 4's lower extreme carries out the heat transfer, the slope setting of the second groove lateral wall 3002 of water receiving tank 30 can make things convenient for the air current through heat exchanger 4 lower extreme to flow along second groove lateral wall 3002, reduce the hindrance of water receiving tank 30 cell wall to the air current, more abundant utilization heat exchanger 4 heat transfer, the heat transfer effect has been improved. In addition, the obtuse-angle inclined arrangement of the side wall of the water receiving tray 3 facilitates the heat exchanger 4 to enter the water receiving tank 30 from a larger notch, so that the assembly of the heat exchanger 4 is facilitated, the space at the bottom of the water receiving tank 30 is increased, and the drainage performance of condensed water is facilitated.

(Structure of emergency water outlet 305 of water tray 3)

In order to avoid the overflow of the condensed water in the drain tray 3 due to the accumulation of the condensed water in the event of a failure of the drain pump 8 or an electrical control failure, as shown in fig. 23 to 25, an emergency drain port 305 is further provided in the drain tray 3, and the emergency drain port 305 is normally closed, so that the emergency drain port 305 needs to be opened only when there is a large amount of water accumulated in the drain tray 3, and the accumulated water is drained from the emergency drain port 305.

Specifically, the emergency drain port 305 is provided to penetrate through the bottom of the water receiving tray 30, and normally, the emergency drain port 305 is plugged by a plug, so that when condensed water accumulates in the water receiving tray 3, the plug is removed, the condensed water flows out of the emergency drain port 305, and the condensed water is prevented from overflowing from the water receiving tray 3 in case of failure.

In some embodiments, since the width d1 of the first groove 302 is larger than the width d2 of the second groove 303, the emergency drain port 305 can be arranged in the first groove 302, so that the emergency drain port 305 can be arranged larger, which is beneficial to the drainage of condensed water and the installation of a sealing plug; the emergency drain port 305 is provided at a lower portion of the bottom of the water receiving tank 30, so that the water in the water receiving tank 30 can flow out conveniently. Since the bottom of the drain tank 30 is the lowest near the drain pump 8, the emergency drain port 305 can be provided near the drain pump 8.

Based on the above-mentioned embodiment, when the emergency drain port 305 is opened to drain, the condensed water in the water receiving tray 3 will flow into the emergency drain port 305 quickly, and the water flow will impact the surrounding parts, therefore, in the ceiling machine, the baffle 306 is disposed on the periphery of the emergency drain port 305, the baffle 306 can block and block the water flow in the area near the emergency drain port 305, and prevent a large amount of water flow from flowing into the emergency drain port 305 quickly, so as to achieve the flow restriction effect of drainage.

The baffle 306 is in an arc shape concentric with the emergency water outlet 305 and is integrally formed with the water pan 3;

specifically, the baffle 306 is arranged outside the quick water discharge port 305, the central angle alpha of the baffle 306 is more than or equal to 30 degrees and less than or equal to 150 degrees, the flow limiting effect of the baffle 306 can be well played, and excessive blocking cannot be caused.

In some embodiments, the emergency drain 305 is disposed near an inner sidewall of the water receiving tank 30, and the baffle 306 is disposed between the emergency drain 305 and the support platform 301, so that when the drain pump 8 sucks the condensed water, the baffle 306 does not obstruct the condensed water in the water receiving tank 30, and when the emergency drain 305 is needed, the baffle 306 can also play a role of limiting the flow.

In addition, when the emergency drain port 305 is used, since the water level in the water receiving tank 30 is generally high, the baffle 306 may be set higher than the support base 301, and the flow restriction may be started at a high water level to reduce the sudden impact of water.

Specifically, as shown in fig. 9 and 12, a protruding ring 3061 is disposed on a side surface of the water receiving tray 3 connected to the foam layer 10, an inner ring of the protruding ring 3061 forms an inner surface of the emergency drain outlet 305, a through hole 106 is correspondingly disposed on the foam layer 10, and the protruding ring 3061 is inserted into the through hole 106. The condensed water flows out through the raised ring 3061 on the water pan 3, so that the condensed water is prevented from contacting the foam layer 10.

Furthermore, a plurality of ribs 3062 radially extend outwards from the outer ring of the protruding ring 3061, a groove 1061 matched with the ribs 3062 is arranged on the through hole 106, and when the assembling position is reached, the ribs 3062 are inserted into the groove 1061, so that the positioning function can be achieved, and the connecting strength of the protruding ring 3061 can be increased.
