Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an integrated air conditioner. Background Art

[0002] Integrated air conditioners, also known as integrated air conditioners, mainly include window air conditioners and mobile air conditioners. Different from conventional split air conditioners, the internal and external units of integrated air conditioners are integrated into one, and the two heat exchangers (evaporator and condenser) are arranged in the same space, with a relatively dense structure layout. It is usually necessary to discharge the condensed water to the location of the condenser to achieve water cooling, promote heat exchange of the condenser, and at the same time allow the condensed water to be discharged in the form of water vapor.

[0003] Among the mobile air-conditioning products currently on the market, the water circulation system for handling condensed water all uses a water pumping motor combined with a single water pump solution. In cooling mode, the heat exchanger at the bottom of the mobile air-conditioning is a condenser, which is installed on the chassis. A water pumping motor with a water pumping wheel is installed at the bottom of the condenser. When the water pumping motor is running, the wind wheel throws the condensed water collected in the chassis onto the condenser by throwing water. In heating mode, the heat exchanger at the top of the mobile air-conditioning is a condenser. The water pumping motor cannot throw the condensed water in the chassis onto the condenser at the top. A water pump is used to pump the condensed water from the chassis to the heat exchanger at the top. However, in cooling mode, the water pumping motor starts as soon as the compressor runs. In other words, in cooling mode, regardless of whether there is condensed water in the chassis, the water pumping motor will always run with the compressor, which is not energy-efficient. In addition, the cost of commonly used AC water pumping motors is relatively high. Utility Model Content

[0004] In view of the above problems, the utility model is proposed to provide an integrated air conditioner that overcomes the above problems or at least partially solves the above problems. It adopts a dual water pump design and also uses a water pump to process condensed water in the cooling mode. In the absence of water or little water, the corresponding water pump can be controlled to shut down, which can solve the problem that the existing air conditioner is not energy-efficient when processing condensed water.

[0005] Specifically, the utility model provides an integrated air conditioner, comprising a first heat exchanger, a second heat exchanger and a water receiving tray, wherein the first heat exchanger is an evaporator in a cooling mode and a condenser in a heating mode; the water receiving tray is used to collect condensed water from the first heat exchanger and the second heat exchanger, and the integrated air conditioner further comprises:

[0006] a first water pump, installed in the water receiving pan, for pumping water in the water receiving pan to the second heat exchanger in a cooling mode;

[0007] a second water pump, installed in the water receiving pan, for pumping water in the water receiving pan to the first heat exchanger in a heating mode;

[0008] A water level detection device is installed in the water receiving tray. The water level detection device is connected to the first water pump and the second water pump, respectively, so as to control the start and stop of the first water pump in the cooling mode and control the start and stop of the second water pump in the heating mode according to the water level in the water receiving tray.

[0009] Optionally, the integrated air conditioner further comprises: a first water sprinkling structure, the first water sprinkling structure is connected to the first water pump, and the first water sprinkling structure is located above the second heat exchanger;

[0011] Optionally, the first heat exchanger is located above the second heat exchanger, and a partition is provided between the first heat exchanger and the second heat exchanger; and the first water sprinkling structure is provided on the partition.

[0012] Optionally, the water level detection device includes an upper detector and a lower detector, the upper detector is used to control the corresponding water pump to start when it detects that the water level in the water receiving tray reaches a first preset water level; the lower detector is used to control the corresponding water pump to shut down when it detects that the water level in the water receiving tray drops to a second preset water level during the pumping process; the first preset water level is greater than the second preset water level.

[0013] Optionally, the water level detection device comprises a float and a guide rod, the float is provided with a magnetic member, and the float is mounted on the guide rod so as to be movable up and down to move up and down with the water surface;

[0014] The upper detector comprises an upper magnetic induction sensor, which is located above the float and is used to obtain a magnetic induction intensity signal of the magnetic member;

[0015] The lower detector comprises a lower magnetic induction sensor, which is located below the float and is used to obtain a magnetic induction intensity signal of the magnetic member.

[0016] Optionally, a limit piece is provided on the guide rod, and the limit piece is located below the float.

[0017] Optionally, the float is a circular ring structure, and the float is sleeved on the guide rod.

[0018] Optionally, a water level limit device is used to detect whether the water in the water receiving tray reaches the highest preset water level when the air conditioner is running, and control the air conditioner to shut down when it reaches the highest preset water level; the water level limit device is connected to the fault reminder device.

[0019] Optionally, filters are provided at the pumping ends of the first water pump and the second water pump.

[0020] Optionally, the integrated air conditioner is a mobile air conditioner or a window air conditioner.

[0021] The integrated air conditioner provided by the utility model is different from the integrated air conditioner on the market that adopts a water-pumping motor combined with a water pump to process condensed water. The air conditioner of the utility model adopts a dual water pump to realize the recycling of condensed water during cooling and heating, and detects whether there is water in the water receiving tray through a water level detection device. When the water in the water receiving tray reaches a certain water level, the corresponding water pump is started to pump water to the condenser, so that the heat exchange efficiency of the condenser is improved; when there is no water or the amount of water in the water receiving tray is small, the water pump does not run. Compared with the water-pumping motor that runs synchronously with the compressor, the energy-saving effect is achieved, and the purpose of improving efficiency and saving energy of the whole machine is achieved.

[0022] Furthermore, water is pumped to the sprinkler structure on the top of the condenser by a water pump, so that the condensed water penetrates downward evenly into the condenser, further improving the heat exchange efficiency.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0034] Figure 1 is a schematic structural diagram of an integrated air conditioner according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 4 , an embodiment of the utility model provides an integrated air conditioner. The integrated air conditioner includes a first heat exchanger 1, a second heat exchanger 2, a reversing device and a water receiving tray 3. The function of the reversing device is to make the first heat exchanger 1 an evaporator in cooling mode and a condenser in heating mode; to make the second heat exchanger 2 a condenser in cooling mode and an evaporator in heating mode. When in use, condensed water will be generated on the surface of the evaporator, and the condensed water will flow into the water receiving tray 3 through the guide structure, or directly drip down to the water receiving tray 3. That is, the water receiving tray 3 is used to collect condensed water from the first heat exchanger 1 and the second heat exchanger 2.

[0035] In this embodiment, the water receiving tray 3 is the chassis of the integrated air conditioner. The reversing device is a four-way reversing valve. The integrated air conditioner is a mobile air conditioner, and the bottom of the water receiving tray 3 is provided with running wheels.

[0036] The integrated air conditioner further includes a first water pump 4, a second water pump 5 and a water level detection device 6, which are installed in the water receiving pan 3. The first water pump 4 and the second water pump 5 are used to pump the condensed water in the water receiving pan 3 upward to the condenser in the cooling mode and the heating mode, respectively. That is, in the cooling mode, the first water pump 4 pumps the water in the water receiving pan 3 to the second heat exchanger 2. In the heating mode, the second water pump 5 pumps the water in the water receiving pan 3 to the first heat exchanger 1.

[0037] The water level detection device 6 is connected to the first water pump 4 and the second water pump 5 respectively, so as to control the start and stop of the first water pump 4 in the cooling mode and the start and stop of the second water pump 5 in the heating mode according to the water level in the water receiving tray 3. Thus, when the water in the water receiving tray 3 reaches a higher water level, the corresponding water pump starts pumping water, and when it drops to a lower water level, the water pump stops pumping water.

[0038] In some embodiments of the utility model, the integrated air conditioner further includes a first water sprinkling structure 7 and a second water sprinkling structure (not shown in the figure), the first water sprinkling structure 7 is connected to the first water pump 4, and the first water sprinkling structure is located above the second heat exchanger 2. The second water sprinkling structure is connected to the second water pump 5, and the second water sprinkling structure is located above the first heat exchanger 1.

[0039] In some embodiments of the present invention, the first heat exchanger 1 is located above the second heat exchanger 2, a partition is provided between the first heat exchanger 1 and the second heat exchanger 2, and the first watering structure 7 is provided on the partition.

[0040] Specifically, the first watering structure 7 and the second watering structure both adopt a watering plate structure.

[0041] In some alternative embodiments of the present invention, the first water sprinkling structure 7 and the second water sprinkling structure may adopt a spray head structure to spray the condensed water downward onto the corresponding condenser.

[0042] In some embodiments of the utility model, the water level detection device 6 includes an upper detector and a lower detector. The upper detector is used to control the corresponding water pump to start when the water level of the water receiving tray reaches the first preset water level. The lower detector is used to control the corresponding water pump to shut down when the water level of the water receiving tray drops to the second preset water level during the pumping process. The first preset water level is the maximum value of the preset threshold range, and the second preset water level is the minimum value of the preset threshold range. The second preset water level can be a zero level or a safe water level.

[0043] In some alternative embodiments of the present invention, the water level detection device 6 may use a set of water level detectors to detect the first preset water level and the second preset water level at the same time.

[0044] In some embodiments of the present invention, Figure 4 As shown, the water level detection device 6 includes a float 61 and a guide rod 63. A magnetic part is provided in the float 61. The float 61 is installed on the guide rod 63 so as to be movable up and down so as to move up and down synchronously with the water surface in the water receiving tray. The upper detector includes an upper magnetic induction sensor, which is located above the float 61 and is used to obtain the magnetic induction intensity signal of the magnetic part of the float 61 and output a voltage signal. The lower detector includes a lower magnetic induction sensor, which is located below the float 61 and is used to obtain the magnetic induction intensity signal of the magnetic part of the float 61 and output a voltage signal. The two magnetic induction sensors are respectively located at the top and bottom of the water level detection device 6 and are symmetrically installed in reverse.

[0045] During the rising process of the water level in the water receiving tray, when it rises to the first preset water level, the upper magnetic induction sensor obtains the magnetic induction intensity signal of the magnetic part of the float 61 to reach a certain value, and controls the corresponding water pump to pump water. The water level continues to drop, and when it drops to the second preset water level, the lower magnetic induction sensor obtains the magnetic induction intensity signal of the magnetic part of the float 61 to reach a certain value, and controls the corresponding water pump to stop pumping water, thereby realizing automatic control of the water level. The water level detection device 6 has the advantage of high measurement accuracy.

[0046] In some embodiments of the utility model, a limiter 62 is provided on the guide rod 63, and the limiter 62 is fixed below the float 61. In this way, the limiter 62 forms a limit on the movable float 61, so that when the water level in the water receiving tray 3 drops to a position lower than the safe water level, the float 61 does not need to continue to drop, shortening the moving path and reducing wear.

[0047] In some embodiments of the present invention, the float 61 is a circular ring structure, and the float 61 is sleeved on the guide rod 63 .

[0048] In some alternative embodiments of the present invention, the float 61 is a floating ball or other floating structures that can float on the water surface.

[0049] In this embodiment, in the water level detection device 6, the position of the float is determined according to the output voltage signals of the two magnetic induction sensors. The two magnetic induction sensors are respectively arranged above and below the float 61, and are used to output corresponding voltage signals according to the position change of the float 61.

[0050] The position of the float is determined according to the output voltage signals of the two magnetic induction sensors, so that the water level of the condensed water in the water receiving tray 3 can be determined. Specifically, the upper / lower detector output signal: the ON state corresponds to the I / O signal being a low level; the OFF state corresponds to the I / O signal being a high level. In the process of the float moving up and down on the guide rod, the triggering modes of the magnetic induction sensors at two different heights are: when the float is at the top, the upper detector is in the ON state, the lower detector is in the OFF state, the upper detector sends a low level signal to the processor, and the lower detector sends a high level signal to the processor. When the float is in the middle, the upper detector and the lower detector are both in the OFF state, and the upper detector and the lower detector both send a low level signal to the processor. When the float is at the bottom, the upper detector is in the OFF state, the lower detector is in the ON state, the upper detector sends a high level signal to the processor, and the lower detector sends a low level signal to the processor.

[0051] In cooling mode, if the program detects that the upper detector of the water level detection device 6 is in the ON state, the first water pump 4 starts and starts pumping water; during the pumping process, when it is detected that the state of the lower detector changes from OFF to ON, the first water pump 4 stops.

[0052] In heating mode, if the program detects that the upper detector of the water level detection device 6 is in the ON state, the second water pump 5 starts and starts pumping water; during the pumping process, when it is detected that the state of the lower detector changes from OFF to ON, the second water pump 5 stops.

[0053] In this embodiment, the water level detection device 6 adopts a mechanical water level gauge in the form of a float switch. In some alternative embodiments of the utility model, the water level detection device 6 can also adopt an ultrasonic water level gauge, a radar water level gauge, a volumetric water level gauge, a capacitive water level gauge, a hydraulic water level gauge, etc.

[0054] Those skilled in the art can flexibly select a suitable water level detection device 6 according to actual design needs. For example, only the upper detector can be retained. The upper detector adopts a water level sensor, and uses the water level sensor to detect the water level in the water receiving tray 3. Once the set height is reached, a signal is sent to the corresponding water pump, thereby starting the water pump. After a preset time, the water pump automatically shuts down, and a "high start and low stop" control mode can also be realized. These are all within the scope of protection of the utility model.

[0055] In some embodiments of the utility model, the integrated air conditioner further includes a water level limit device 8 and a fault reminder device, and the water level limit device 8 and the fault reminder device are connected. The structure of the water level limit device 8 is the same as that of the water level detection device 6, and the installation position of the water level limit device 8 is higher than the water level detection device 6. When the air conditioner is running, the water level limit device 8 detects whether the water in the water receiving tray 3 reaches the highest preset water level, and controls the air conditioner to stop when it reaches the highest preset water level, and the fault reminder device reports a water full fault. In other words, no matter what mode the air conditioner is running in, if the water level limit device 8 is activated, the whole machine will stop and report a water full fault.

[0056] In some embodiments of the utility model, a filter 9 is provided at the pumping end of the first water pump 4 and the second water pump 5. A collection area and a clean water area are provided in the water receiving tray 3. The condensed water flowing down from the heat exchanger is collected in the collection area of ​​the water receiving tray 3. The pumping end of the water pump extends into the clean water area. The filter 9 is located between the collection area and the clean water area. A filter is added to the pumping end of the water pump to filter impurities in the condensed water. Considering the purity of the condensed water in the water receiving tray 3, it is prevented that particulate impurities are pumped into the water pump when the water pump is pumping water, which will affect the flow rate of the water pump and reduce the impact of long-term use on the life of the water pump.

[0057] In some embodiments of the utility model, a first drain port 10 is provided on the partition, and the first drain port 10 is connected to the first sprinkler structure 7. The water receiving tray 3 is provided with a second drain port 11, and the second drain port 11 is connected to the water outlet end of the first water pump 4. In one use case, a water pipe (not shown in the figure) is connected between the first drain port 10 and the second drain port 11, and the condensed water in the water receiving tray 3 is transported to the first sprinkler structure 7 on the partition along the water pipe through the first water pump 4. In another use case, a first cover is detachably installed on the first drain port 10, and the condensed water on the partition can be directly discharged through the first drain port 10. A second cover is detachably installed on the second drain port 11, and the first water pump 4 can quickly pump out the condensed water in the water receiving tray 3 through the second drain port 11.

[0058] In this embodiment, the integrated air conditioner is a mobile air conditioner. In some alternative embodiments of the present utility model, the integrated air conditioner is a window air conditioner.

[0059] The internal and external units of a mobile air conditioner or a window air conditioner are integrated into one, arranged in the same space, and have a relatively dense structure. The arrangement method of the utility model can be used. That is, two water pumps are arranged on the water receiving tray, respectively used for the condenser in different modes, and the versatility is high.

[0060] The working process of the integrated air conditioner of the utility model embodiment is as follows:

[0061] When the air conditioner is running in cooling mode, the first heat exchanger 1 at the top is an evaporator, which will produce condensed water, which will gather in the water receiving tray 3. At this time, the second heat exchanger 2 at the bottom is a condenser. When the upper detector in the water level detection device 6 is detected to be actuated, the first water pump 4 is activated and starts to pump water, pumping the condensed water in the water receiving tray 3 to the first water sprinkling structure located above the second heat exchanger 2. The condensed water flows evenly to the second heat exchanger 2 through the water sprinkling tray structure, thereby improving the heat exchange efficiency. The first water pump 4 stops pumping water until the lower detector is actuated.

[0062] When the air conditioner is in heating mode, the first heat exchanger 1 at the top is the condenser, and the second heat exchanger 2 at the bottom is the evaporator. The condensed water generated by the evaporator is collected in the water receiving tray 3. When the upper detector in the water level detection device 6 is detected to be actuated, the second water pump 5 is activated to start pumping water, and the condensed water in the water receiving tray 3 is pumped to the second water sprinkling structure above the first heat exchanger 1. The condensed water flows evenly to the first heat exchanger 1 through the water sprinkling tray structure, thereby improving the heat exchange efficiency. The second water pump 5 stops pumping water until the lower detector is actuated.

[0063] The air conditioner of the utility model adopts a dual water pump design, which is different from the condensate water treatment method of the mobile air conditioners on the market that uses a water pumping motor combined with a water pump. When the mobile air conditioner products on the market are running in the cooling mode, they only rely on the water pumping motor to run the water throwing scheme to the condenser. The utility model uses a water pump to pump water to the water sprinkling structure on the top of the condenser, so that the condensate water evenly penetrates the condenser, improving the heat exchange efficiency.

[0064] When the mobile air conditioner on the market is running in cooling mode, as long as the compressor is started, the water pumping motor will run. When there is no condensed water in the chassis, the water pumping motor will idle, increasing energy consumption. When the air conditioner of the utility model is in cooling mode, it will detect whether there is water in the water receiving tray through the water level detection device. When the water in the water receiving tray reaches a certain water level, the corresponding water pump is started to pump water to the condenser, so that the heat exchange efficiency of the condenser is improved. When there is no water or less water in the water receiving tray, the water pump does not run. Compared with the water pumping motor that runs all the time, the purpose of energy saving is achieved.

[0065] Therefore, for integrated air conditioners, especially mobile air conditioners, a water pump is used in the cooling mode, thus forming a dual water pump design, which can not only better improve the heat exchange efficiency of the condenser, but also save energy, thereby achieving a better user experience.

[0066] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
