The utility model provides an air conditioner and water heater integrated machine. Referring to fig. 1 to 5, fig. 1 is a schematic structural diagram of an embodiment of an air conditioner and water heater integrated machine according to the present utility model; the first air outlet of the hollow water heater integrated machine of fig. 2 and 3 is turned off and the second air outlet is turned on; the first air outlet of the hollow water heater all-in-one machine of fig. 4 and 5 is turned on and the second air outlet is turned off. In an embodiment of the air-conditioning and water-heating integrated machine of the present utility model, the air-conditioning and water-heating integrated machine includes:

the casing 10 is provided with an air duct 11, an air inlet 12, a first air outlet 13 and a second air outlet 14 which are all communicated with the air duct 11, wherein the first air outlet 13 is communicated with the outdoor space 101, and the second air outlet 14 is communicated with the indoor space 102;

the air outlet switching mechanism 15 is movably arranged on the casing 10 and is used for leading the first air outlet 13 and the second air outlet 14 to be selectively communicated with the air inlet 12;

the fan 16 is at least partially arranged in the air duct 11 and is used for driving air to flow from the air inlet 12 to the first air outlet 13 and/or the second air outlet 14; and

the heat exchange assembly comprises a refrigerant module and a heat storage module which are both arranged on the shell 10, wherein the refrigerant module comprises a compressor 171, and a first heat exchanger 172 and a second heat exchanger 173 which are both communicated with the compressor 171, the first heat exchanger 172 is arranged in the air duct 11, the heat storage module comprises a water storage cavity 174 and a water inlet channel (not shown in the drawing) which are communicated, and the refrigerant in the second heat exchanger 173 can exchange heat with water in the water storage cavity 174 and/or the water inlet channel, and the water storage cavity 174 is provided with a water outlet (not shown in the drawing) for supplying water to the outside.

Specifically, the air conditioner and water heater integrated machine has the functions of both the heat pump water heater and the air conditioner at least, specifically, when the refrigerant module works so that the refrigerant in the second heat exchanger 173 is in a high temperature state, the heat of the second heat exchanger 173 can be transferred and stored in the water storage cavity 174, and then the hot water in the water storage cavity 174 can be provided outwards through the water outlet, so that the hot water use requirement of a user is met, namely, the function of the heat pump water heater is realized; at this time, the first air outlet 13 communicating with the outdoor space 101 is turned on so that the air flowing through the first heat exchanger 172 is directly discharged to the outdoor space 101.

On the basis of the heat pump water heater function, by arranging the second air outlet 14 and the air outlet switching mechanism 15 which are communicated with the indoor space 102, when the indoor space 102 needs to use the refrigerating function, the air outlet switching mechanism 15 conducts the second air outlet 14 with the air inlet 12 and cuts off the conduction between the first air outlet 13 and the air inlet 12, so that the air flowing through the first heat exchanger 172 and being cooled flows to the indoor space 102, and refrigerating regulation of the indoor space 102 is realized. It will be appreciated that the conduction between the first air outlet 13 and the second air outlet 14 and the air inlet 12 will not affect the heating of the water in the heat storage module by the second heat exchanger 173, i.e. will not affect the normal use of the heat pump water heater.

It can be understood that the air-conditioning and water-heating integrated machine of the present utility model provides at least two operation modes for user selection, including a single hot water mode and a refrigeration mode, wherein the air-out switching mechanism 15 in the single hot water mode enables the second air-out port 14 to be communicated with the air-in port 12, and the air-out switching mechanism 15 in the refrigeration mode enables the first air-out port 13 to be communicated with the air-in port 12. When the indoor space has no cooling requirement, for example, in cold winter, the user can control the air conditioner/water heater integrated machine to enter a single hot water mode, so that the air flowing through the first heat exchanger 172 and cooled down directly flows to the outdoor space, and sufficient hot water supply can be ensured. When the indoor space has a refrigerating requirement, for example, in hot summer, a user can control the air-conditioning water heater integrated machine to enter a refrigerating mode, so that the air after refrigerating flows into the indoor space, and heat can be stored in water in the water storage cavity.

According to the technical scheme, the first air outlet 13, the second air outlet 14 and the air outlet switching mechanism 15 are arranged, so that the air-conditioning water heater integrated machine can fully utilize the first heat exchanger 172 and the second heat exchanger 173 on the refrigerant module, better energy saving and environment protection effects are achieved, and free switching between a single hot water mode and a refrigerating mode can be achieved, and therefore diversified requirements of users are better met. Specifically, when the indoor space 102 needs a refrigeration function, the air-conditioning and water-heating integrated machine of the utility model heats the water in the heat storage module by using the second heat exchanger 173, and simultaneously, the air cooled by the first heat exchanger 172 flows to the indoor space from the second air outlet 14, so that the refrigeration of the indoor space 102 is realized, and the energy consumption for refrigerating the indoor space by adopting other additional refrigeration equipment can be saved.

It should be noted that, the air-conditioning water heater integrated machine can be placed in the outdoor space 101 as an integrated machine structure so that the air inlet 12 can be directly exposed in the outdoor space 101, thereby introducing outdoor fresh air and refrigerating the air, and then sending the air into the indoor space 102 through the second air outlet 14, so as to realize a fresh air function. Of course, in other embodiments, the air conditioner/water heater integrated machine may be placed in the indoor space 102, and then an outdoor air guide pipe is externally connected to the air inlet 12, and the air inlet end of the outdoor air guide pipe extends to the outdoor space 101 so as to introduce outdoor fresh air.

For example, when the air conditioner water heater integrated machine is used as a kitchen air conditioner, the air conditioner water heater integrated machine can be placed on a balcony outside a kitchen, so that oil smoke in the kitchen can be prevented from entering the air conditioner water heater integrated machine from the air inlet 12, and outdoor fresh air can be introduced to refrigerate the kitchen, the problem that the filter screen and the air duct 11 are polluted by the oil smoke in the existing kitchen air conditioner is solved, sufficient fresh air is provided for the kitchen, and the comfort and the air quality of the indoor environment are improved. In addition, the warm water in the heat storage module can be used as kitchen water, so that a user can use the warm water in a kitchen conveniently, and the use experience of the user is further improved.

Further, the air conditioner and water heater integrated machine can provide three working modes for a user to select, wherein the three working modes comprise a single hot water mode, a refrigerating mode and a fresh air mode, and the refrigerating mode and the fresh air mode both adopt a structure form that the second air outlet 14 is communicated with the air inlet 12, but the refrigerating efficiency is different. Specifically, when the air conditioner and water heater integrated machine enters the fresh air mode, the compressor 171 operates with lower power, so that the refrigeration efficiency is at a lower level on the premise of meeting the requirement of cooling outdoor air, and in this way, the function of the fresh air mode can be maintained for a longer time in the process of heating the water with the same volume to the preset temperature. When the air-conditioning water heater unit enters the cooling mode, indicating that the user needs a high-efficiency cooling function, the compressor 171 is operated at a high or highest power to achieve a high or highest level of cooling efficiency. Of course, the function of the cooling mode can only be maintained for a short time during the heating of the equal volume of water to the preset temperature, but the advantage of this mode of operation is also apparent in view of its capability of satisfying the urgent cooling needs of the user. Therefore, a user can freely control the air conditioner and water heater integrated machine to switch in three working modes according to different use requirements, and user experience is further improved.

Referring to fig. 9 and 10, in order to facilitate the user to introduce the cold air into the indoor space 102, in an embodiment, the air-conditioning and water-heater integrated machine further includes an indoor ventilation pipe 20, one end of the indoor ventilation pipe 20 is connected to the second air outlet 14, and the other end extends into the indoor space 102. In this embodiment, alternatively, the indoor ventilation pipe 20 is detachably connected with the second air outlet 14 by means of clamping or screwing, so that a user can conveniently choose and install the indoor ventilation pipe 20 according to the actual placement position of the air-conditioning water heater integrated machine. That is, the indoor ventilation duct 20 is installed only when the air-conditioning water heater integrated machine is placed in the outdoor space 101, and the indoor ventilation duct 20 may not be installed when the air-conditioning water heater integrated machine is placed in the indoor space 102. Of course, in other embodiments, the indoor ventilation duct 20 may not be provided, or the indoor ventilation duct 20 may be fixedly connected to the second air outlet 14.

In an embodiment, the air-conditioning and water-heater integrated machine further includes an indoor air outlet frame 30 disposed in the indoor space 102, and a display module and/or a control key and/or a wireless signal receiving module disposed in the indoor air outlet frame 30. Therefore, the air conditioner and water heater integrated machine can be conveniently and directly regulated and controlled indoors by a user, and the operation parameter information of the air conditioner and water heater integrated machine is seen, so that the use convenience of the air conditioner and water heater integrated machine is improved, and the user experience is improved. Specifically, alternatively, the display module may be a display screen or a display panel, the control key may be a physical key or a touch key, and the wireless signal receiving module may be an infrared receiver or a bluetooth module. Of course, in other embodiments, the display module may be disposed only on the indoor air outlet frame 30, and then the control key and the wireless signal receiving module may be disposed on the casing 10.

Referring to fig. 8 to 10, in an embodiment, the indoor air outlet frame 30 is provided with a mounting structure, and the mounting structure is mounted on a wall hole of the indoor space 102 and/or a ceiling 103 hole. The indoor space 102 includes holes in the wall, holes in the ceiling 103, and a space above the ceiling 103. Thus, the indoor air outlet frame 30 is conveniently installed on the wall or the suspended ceiling 103 by a user. Specifically, the mounting structure is configured as a clamping structure, for example, a spring clip structure used for the ceiling 103 lamp may be referred to, or the mounting structure is directly formed on the outer peripheral wall of the indoor air outlet frame 30, that is, the indoor air outlet frame 30 is directly embedded in the hole. Of course, in other embodiments, the indoor air outlet frame 30 may be configured to be movable, for example, a tripod is disposed at the bottom thereof, and the user can move the tripod and the indoor air outlet frame 30 thereon at will to place it at any indoor location.

Referring to fig. 2 to 7, in an embodiment, the air duct 11 includes a first pipe section 111 and a second pipe section 112 that intersect, an air outlet end of the first pipe section 111 is communicated with the first air outlet 13, an air outlet end of the second pipe section 112 is communicated with the second air outlet 14, and an air outlet switching mechanism 15 is movably disposed at an intersection of the first pipe section 111 and the second pipe section 112. In this way, the air-out switching mechanism 15 is built in the duct 11, and can provide a good protection effect. Of course, in other embodiments, the air outlet switching mechanism 15 may be further disposed outside the first air outlet 13, that is, outside the casing 10, and may movably cover the first air outlet 13.

In one embodiment, the air outlet switching mechanism 15 includes a valve plate 151 rotatably connected to the air duct 11, and a driving member (not shown in the drawing) drivingly connected to the valve plate 151, where the valve plate 151 is rotatably covered on the air inlet end of the first pipe section 111 or the air inlet end of the second pipe section 112. In this way, the structure of the valve plate 151 can be simplified, thereby reducing the manufacturing cost. In particular, the driving member is configured as one of an electric motor, a hydraulic motor, and a pneumatic motor. Of course, in some embodiments, the air outlet switching mechanism 15 may be configured as a telescopic plate structure, where one end of the telescopic plate is fixedly arranged on one side of the air duct 11, and the other end of the telescopic plate is movably extended to the other side of the air duct 11. In other embodiments, the air-out switching mechanism 15 may be further configured as a slider that can slide at the intersection of the first pipe section 111 and the second pipe section 112 to selectively block both the air-in end of the first pipe section 111 and the air-in end of the second pipe section 112.

In an embodiment, the valve plate 151 is rotatably disposed at the air inlet end of the second pipe section 112 and is close to the inner wall of the first pipe section 111, the air inlet end of the first pipe section 111 is provided with a first protruding rib 113 on the inner wall far from the second pipe section 112, and the first protruding rib 113 is used for abutting the free end of the valve plate 151; and/or, the air inlet end of the second pipe section 112 is provided with a second convex rib 114 on the inner wall far away from the first pipe section 111, and the second convex rib 114 is used for abutting against the free end of the valve plate 151. That is, the valve plate 151 rotates between the first rib 113 and the second rib 114, has a simple structure and a good limiting effect, and also can lift the air tightness between the free end of the valve plate 151 and the inner wall of the air duct 11, thereby lifting the intercepting effect of the valve plate 151. Of course, in other embodiments, the driving member may be configured as a structure capable of precisely controlling the rotation angle, such as a servo motor, without providing the first rib 113 and the second rib 114.

In one embodiment, the fan 16 is configured as a centrifugal fan 16, the air duct 11 includes a volute section 115, an air inlet end of the volute section 115 is communicated with the air inlet 12, and the centrifugal fan 16 is disposed in the volute section 115. In this way, the ability of the blower 16 to deliver air to the indoor space 102 can be increased, thereby increasing the force of the air being supplied at the indoor air outlet frame 30. Also, in the embodiment in which the axial direction of the centrifugal fan 16 is arranged in the horizontal direction, the axial dimension of the centrifugal fan 16 is small, so that the width dimension of the casing 10 in the horizontal plane is advantageously reduced. Specifically, the high static pressure centrifugal fan 16 may be selected to further boost the force of the supplied air. Of course, in other embodiments, the fan 16 may also employ an axial fan 16 or a cross-flow fan 16.

In an embodiment, the air outlet end of the volute section 115 is connected to the intersection of the first pipe section 111 and the second pipe section 112, the second pipe section 112 extends upward, the second air outlet 14 is disposed on the top surface of the casing 10, and the air inlet 12 is disposed on the side surface of the casing 10. In this way, the air is advantageously conveyed to the indoor ventilation pipe 20 and the indoor air outlet frame 30 at a higher position, and the air can flow in the air duct 11 more smoothly. Optionally, in this embodiment, the first pipe section 111 extends in a transverse direction, and the first air outlet 13 is disposed on a side surface of the casing 10, so that by separating the first air outlet 13 and the second air outlet 14 on adjacent wall surfaces of the casing 10, air can flow in the air duct 11 more smoothly, and the movement stroke of the valve plate 151 is further reduced. Of course, in other embodiments, the first pipe section 111 may extend upward, and the first air outlet 13 is disposed on the top surface of the casing 10; alternatively, the first pipe section 111 and the second pipe section 112 extend in a transverse direction, and the first air outlet 13 and the second air outlet 14 are disposed on the side surface of the casing 10.

In one embodiment, the first heat exchanger 172 is disposed within the volute section 115 and between the centrifugal fan 16 and the air intake 12. Thus, the arrangement of the volute section 115 and the centrifugal fan 16 is facilitated, and the air flow in the air duct 11 is smoother. Of course, in other embodiments, the first heat exchanger 172 may be disposed within the volute section 115 on a side of the centrifugal fan 16 remote from the intake 12.

Referring to fig. 5 and 7, in an embodiment, the second heat exchanger 173 is configured as a microchannel flat tube heat exchanger or a coil heat exchanger, and the second heat exchanger 173 is disposed in the water storage cavity 174. Thus, the second heat exchanger 173 is directly immersed in the water storage chamber 174 to improve the heat exchange efficiency and heat recovery rate of the refrigerant and the water.

In an embodiment in which the second heat exchanger 173 is configured as a microchannel flat tube heat exchanger or a coil heat exchanger, optionally, the heat storage module further includes a water inlet pipe, a water inlet control valve, and a water outlet pipe, the water storage cavity 174 includes a first cavity, a one-way valve, and a second cavity that are sequentially communicated, the second heat exchanger 173 is disposed in the first cavity, the first cavity is communicated with the water inlet pipe and the water inlet control valve, and the second cavity is communicated with the water outlet pipe. In the initial state, water is injected into the first cavity, the second cavity is empty, when the water in the first cavity exchanges heat with the refrigerant and the temperature rises to a preset temperature, hot water flows into the second cavity from the first cavity through the one-way valve to store the hot water, and then the water inlet control valve is used for leading the water inlet pipe and an external water source to inject new cold water or warm water into the first cavity. In this way, the temperature difference between the water in the first cavity and the refrigerant in the second heat exchanger 173 can be increased, thereby being beneficial to improving the heat exchange efficiency and the heat recovery rate.

Of course, the structure of the second heat exchanger 173 is not limited thereto, and in other embodiments, the second heat exchanger 173 is configured as a plate heat exchanger, which is disposed outside the water storage chamber 174, and the water inlet passage is at least partially formed therein. Without loss of generality, a refrigerant channel and a water flowing channel are generally arranged in the plate heat exchanger at intervals, two ends of the refrigerant channel are respectively provided with a refrigerant liquid inlet interface and a refrigerant liquid outlet interface, the refrigerant liquid inlet interface and the refrigerant liquid outlet interface are respectively communicated with a liquid outlet of the first heat exchanger 172 and a liquid inlet of the compressor 171, two ends of the water flowing channel are respectively provided with a water inlet interface and a water outlet interface, the water inlet interface and the water outlet interface are respectively communicated with a water inlet of the water inlet pipe and the water storage cavity 174, and the water inlet pipe is communicated with an external water source, such as a tap of tap water on a balcony, so that water is introduced into the plate heat exchanger. After the heat exchange with the refrigerant in the refrigerant channel, the water flowing into the plate heat exchanger flows into the water storage cavity 174 for subsequent hot water supply. Of course, in other embodiments, a plate heat exchanger and a micro-channel flat tube heat exchanger (or coil heat exchanger) may be configured at the same time, where the plate heat exchanger is disposed outside the water storage chamber 174, and the micro-channel flat tube heat exchanger (or coil heat exchanger) is disposed inside the water storage chamber 174.

Without loss of generality, the heat transfer coefficient of the plate heat exchanger is 3 to 5 times higher than that of the tubular heat exchanger under the condition of the same power consumption, the occupied space is one third of that of the tubular heat exchanger, and the heat recovery rate can be up to more than 90%. That is, the plate heat exchanger has smaller volume and higher heat exchange efficiency, so that more arrangement space is provided in the casing 10 to arrange the water storage chamber 174, thereby making the volume of the water storage chamber 174 larger, and the arrangement outside the water storage chamber 174 without occupying the water storage volume inside the water storage chamber 174, and further increasing the volume of the water storage chamber 174. It will be appreciated that the greater the volume of the water storage chamber 174, the more advantageous it is to increase the available time for fresh air mode and for cooling mode. For example, when the volume of the water storage chamber 174 is configured to be 150 liters, and a cool fresh air is supplied to the room at a flow rate of 200 cubic meters per hour in the fresh air mode, the fresh air mode can be maintained for approximately 12 hours. It will be appreciated that the present utility model enables zero water consumption over a longer refrigeration use time than a water-cooled air conditioner that requires continuous supply of cold water and discharge of hot water to cool the second heat exchanger.

Of course, the second heat exchanger 173 may be configured in other configurations, and those skilled in the art may select the configuration according to design requirements.

Referring to fig. 3, 5 and 7, in an embodiment, the water storage chamber 174 is disposed at the bottom of the casing 10, and the compressor 171, the first heat exchanger 172, the air duct 11 and the fan 16 are disposed on the upper side of the water storage chamber 174. In this way, the compressor 171, the first heat exchanger 172, the air duct 11 and the fan 16 are uniformly arranged at the top of the casing 10, and the bottom space of the casing 10 is provided for the water storage cavity 174 as much as possible, so that the volume of the water storage cavity 174 can be increased, and the gravity center of the air-conditioning water heater integrated machine can be gradually reduced along with more and more water stored in the water storage cavity 174, that is, the gravity center of the air-conditioning water heater integrated machine is also reduced, so that the stability of placing and mounting of the air-conditioning water heater integrated machine is improved.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
