Description

Technical Field

[0001] This utility model relates to the field of process control equipment, and in particular to a plate heat exchanger, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] Air conditioning is used to regulate indoor air and keep it in a state most suitable for people. For example, in summer when the indoor temperature is high, it cools the room by blowing out cool air, while in winter it heats the room by blowing out warm air.

[0003] However, current air conditioners are generally small and have limited air volume. In large rooms, a single air conditioner cannot provide rapid heating or cooling. Users can only choose to install multiple air conditioners, but this is expensive. Therefore, how to achieve rapid cooling and heating in large rooms at low cost is an urgent problem to be solved. Utility Model Content

[0004] One objective of this utility model is to improve the heat exchange efficiency of the indoor unit of an air conditioner while reducing the cost of the indoor unit.

[0005] A further objective of the first aspect of this utility model is to save room space occupied by the indoor unit of the air conditioner.

[0006] Another further objective of the first aspect of this utility model is to avoid noise caused by poor matching between the ceiling fan rod and the plate heat exchanger of the air conditioner indoor unit.

[0007] Another further objective of the first aspect of this utility model is to ensure that the plate heat exchanger of the indoor unit of the air conditioner and the ceiling fan can work well together.

[0008] The second aspect of this utility model is to provide an indoor air conditioning unit.

[0009] The third aspect of this utility model is to provide an air conditioner.

[0010] Specifically, this utility model provides a plate heat exchanger, which belongs to the category of air conditioner indoor units and is located outside the air conditioner indoor unit, comprising:

[0011] The heat exchange plate has a first through hole along its thickness for the hanging rod of the ceiling fan to pass through, so that the indoor air stirred by the ceiling fan to the vicinity of the plate heat exchanger can be heated by the plate heat exchanger.

[0012] Optionally, the heat exchange plate is rectangular, and the first through hole is located in the middle of the heat exchange plate.

[0013] Optionally, the first through hole of the heat exchange plate is adapted to the shape of the hanging rod of the ceiling fan.

[0014] Optionally, after the ceiling fan's suspension rod is assembled into the first through hole, the wall of the first through hole and the wall of the ceiling fan's suspension rod are in contact.

[0015] Optionally, a plurality of parallel second through holes are formed at intervals on both sides of the first through hole along its length direction in the heat exchange plate. Each second through hole is used for a heat exchange tube to pass through, and the heat exchange tube is used for a refrigerant to flow through.

[0016] Optionally, the second through hole and the heat exchange tube are adapted in shape.

[0017] Optionally, the second through hole is a columnar through hole.

[0018] Optionally, ten parallel second through holes are formed on both sides of the first through hole along its length in the heat exchange plate.

[0019] According to another aspect of the present invention, an air conditioning indoor unit is also provided, which includes a plate heat exchanger as described in any of the preceding claims.

[0020] According to another aspect of the present invention, an air conditioner is also provided, which includes the air conditioner indoor unit as described above.

[0021] This utility model proposes a plate heat exchanger, an indoor air conditioning unit, and an air conditioner. The plate heat exchanger, belonging to the indoor air conditioning unit and located outside the unit, includes heat exchange plates. Each heat exchange plate has a first through hole along its thickness for a ceiling fan's rod to pass through, allowing air stirred by the ceiling fan to be heated by the plate heat exchanger. Based on the technical solution proposed in this utility model, the ceiling fan can cooperate with the plate heat exchanger by passing its rod through the first through hole on the heat exchange plate. The ceiling fan functions similarly to the air blower in the indoor air conditioning unit, eliminating the need for a fan and guide plates in the indoor unit, thus reducing its cost. Furthermore, the indoor air conditioning unit does not need to be installed indoors, saving space.

[0022] Furthermore, this utility model achieves room heat exchange by using a ceiling fan in conjunction with a plate heat exchanger. The ceiling fan is larger than the fan of an air conditioner indoor unit, covering a wider area, thus ensuring no dead corners in the room. When the ceiling fan is working, the room air is constantly circulating due to the fan's agitation; higher-temperature air rises while lower-temperature air sinks. The plate heat exchanger is in the constantly moving indoor air and can exchange heat with it, thereby achieving rapid cooling or heating of the room and rapid temperature changes throughout the room.

[0023] Furthermore, this utility model combines a ceiling fan with a plate heat exchanger to achieve room heat exchange. The area of ​​the plate heat exchanger can be designed arbitrarily according to the size of the room space, thereby meeting the actual needs of users and improving the user experience.

[0024] Furthermore, the heat exchange plate in this invention is rectangular, and the first through hole is located in the middle of the heat exchange plate, so that almost all the air stirred by the ceiling fan to the vicinity of the plate heat exchanger can be heat exchanged per unit time, thereby improving the heat exchange efficiency of the plate heat exchanger and realizing rapid cooling or heating of the room.

[0025] Furthermore, in this invention, the first through hole of the heat exchange plate is compatible with the shape of the ceiling fan rod, and after the ceiling fan rod is assembled into the first through hole, the hole wall of the first through hole and the rod wall of the ceiling fan rod fit together. This avoids the ceiling fan rod from colliding with the inner wall of the first through hole during operation, thus preventing noise from being generated and affecting the user, while also ensuring the working efficiency of the ceiling fan.

[0026] Furthermore, in this invention, multiple parallel second through holes are formed on both sides of the first through hole along its length direction within the heat exchange plate. Each second through hole is used for the heat exchange tube to pass through, and the heat exchange tube is used for the refrigerant to flow through. The multiple second through holes are arranged parallel to each other along the length direction of the heat exchange plate on one side of the first through hole, and on the other side of the first through hole. By designing the second through holes to avoid the first through hole, interference between the heat exchange tube and the ceiling fan rod can be avoided when the ceiling fan and the plate heat exchanger are used together, ensuring that the plate heat exchanger and the ceiling fan can work well together.

[0040] Figure 1 This is a schematic diagram of a plate heat exchanger and a ceiling fan assembled in an indoor environment according to an embodiment of the present invention.

[0041] See Figure 1 As shown, the ceiling fan 2 includes a hanging rod 20 and a fan head 30. One end of the hanging rod 20 is fixed to the ceiling in the room, and the other end of the hanging rod 20 is provided with the fan head 30, which includes fan blades. The entire ceiling fan 2 is suspended in the room.

[0042] Figure 2 This is a schematic diagram of the overall structure of a plate heat exchanger according to an embodiment of the present invention.

[0043] See Figure 1 , 2 As shown, the plate heat exchanger 100 is an indoor unit of an air conditioner and is located outside the indoor unit. The plate heat exchanger 100 can be installed on the ceiling of the room, which is lower than the ceiling. Specifically, the upper parts of the two side walls of the room can extend into the room in the direction of width, with a first extension 3 and a second extension 4 respectively. The two sides of the plate heat exchanger 100 can be mounted on the ceiling of the room by being placed on the first extension 3 and the second extension 4 respectively, and the bottom surface of the plate heat exchanger 100 is exposed to the indoor environment. The plate heat exchanger 100 includes a heat exchange plate 110, which can be made of a material with good thermal and cold conductivity, such as stainless steel or copper. The heat exchange plate 110 has a first through hole 111 along its thickness direction for the hanging rod 20 of the ceiling fan 2 to pass through, so that the plate heat exchanger 100 can exchange heat with the air stirred up by the ceiling fan 2 to the vicinity of the plate heat exchanger 100.

[0044] When installing the plate heat exchanger 100 in an indoor environment, the ceiling fan 2 can be removed from the ceiling as a whole. After the plate heat exchanger 100 is installed, the end of the ceiling fan 2's hanging rod 20 that is connected to the ceiling is passed through the first through hole 111 of the heat exchange plate 110 so that the ceiling fan 2 is installed and fixed on the ceiling as a whole.

[0045] Alternatively, when the plate heat exchanger 100 is installed indoors, the ceiling fan head 30 can be removed from the hanging rod 20. After the end of the hanging rod 20 connected to the ceiling fan head 30 passes through the first through hole 111 of the heat exchange plate 110, the ceiling fan head 30 can be reassembled onto the hanging rod 20.

[0046] The plate heat exchanger 100 proposed in this embodiment is an indoor unit of an air conditioner and is located outside the indoor unit. The plate heat exchanger 100 includes a heat exchange plate 110, and the heat exchange plate 110 has a first through hole 111 along its thickness direction for the hanging rod 20 of the ceiling fan 2 to pass through, so that the plate heat exchanger 100 can exchange heat with the air stirred by the ceiling fan head 30 to the vicinity of the plate heat exchanger 100. Based on the technical solution proposed in this utility model, based on the first through hole 111 provided on the heat exchange plate 110, the ceiling fan 2 can be used in conjunction with the plate heat exchanger by passing its hanging rod 20 through the first through hole. The function of the ceiling fan 2 is equivalent to the air supply fan in the indoor unit of the air conditioner. There is no need to install a fan and guide plate in the indoor unit of the air conditioner, which reduces the cost of the indoor unit of the air conditioner. In addition, the indoor unit of the air conditioner does not need to be installed in the room, saving space.

[0047] Furthermore, room heat exchange is achieved by using the ceiling fan 2 in conjunction with the plate heat exchanger 100. The fan of the ceiling fan 2 is larger than that of the air conditioner indoor unit, and its coverage area is wider, thus eliminating dead corners in the whole room. When the ceiling fan 2 is working, the room air is stirred by the ceiling fan 2, and the air with higher temperature rises and the air with lower temperature sinks, and the whole room is in a continuous circulation. At this time, the plate heat exchanger 100 is in the continuously moving indoor air and can exchange heat with the indoor air, thereby achieving rapid cooling or heating of the room and rapid temperature change throughout the room.

[0048] Furthermore, the ceiling fan 2 is used in conjunction with the plate heat exchanger 100 to achieve room heat exchange. The area of ​​the plate heat exchanger 100 can be designed arbitrarily according to the size of the room space, thereby meeting the actual needs of users and improving the user experience.

[0049] In addition to being used in conjunction with the plate heat exchanger 100, the ceiling fan 2 can also be used independently. When the user does not need the plate heat exchanger 100 to work but only needs the ceiling fan 2 to work, only the ceiling fan 2 can be turned on. In this case, the ceiling fan 2 simply acts as a fan. This setting can meet the user's various needs for the indoor environment and improve the user experience.

[0050] In some preferred or alternative embodiments of the present invention, the heat exchange plate 110 is rectangular, and the first through hole 111 is disposed in the middle position of the heat exchange plate 110.

[0051] The heat exchange plate 110 is rectangular, and the first through hole 111 is located in the middle of the heat exchange plate 110. This allows almost all the air stirred by the ceiling fan 2 to the vicinity of the plate heat exchanger 100 to be heat-exchanged per unit time, thereby improving the heat exchange efficiency of the plate heat exchanger 100 for indoor air, thus realizing rapid cooling or heating of the room and improving the user experience.

[0052] In practical applications, the shape of the heat exchange plate 110 can be determined according to the actual indoor environment, and this utility model does not impose too many restrictions on it.

[0053] In some preferred or alternative embodiments of the present invention, the first through hole 111 of the heat exchange plate 110 and the hanging rod 20 of the ceiling fan 2 are adapted in shape.

[0054] The first through hole 111 of the heat exchange plate 110 is adapted to the shape of the hanging rod 20 of the ceiling fan 2, so that the hanging rod 20 of the ceiling fan 2 can pass smoothly through the first through hole 111 of the heat exchanger 110.

[0055] In some preferred or alternative embodiments of the present invention, the first through hole 111 of the heat exchange plate 110 is a cylindrical through hole, and the hanging rod 20 of the ceiling fan 2 is a cylindrical hanging rod.

[0056] The suspension rod 20 is generally a cylindrical suspension rod, therefore, the first through hole 111 of the heat exchange plate 110 is also designed as a cylindrical through hole.

[0057] In practical applications, the shape of the first through hole 111 of the heat exchange plate 110 can be determined according to the shape of the hanging rod 20 of the ceiling fan 2. This utility model does not impose too many restrictions on this.

[0058] In some preferred or alternative embodiments of the present invention, after the hanging rod 20 of the ceiling fan 2 is assembled into the first through hole 111 of the heat exchange plate 110, the hole wall of the first through hole 111 of the heat exchange plate 110 and the rod wall of the hanging rod 20 of the ceiling fan 2 are in contact.

[0059] When the hanging rod 20 of the ceiling fan 2 is assembled into the first through hole 111, the hole wall of the first through hole 111 of the heat exchange plate 110 and the rod wall of the hanging rod 20 of the ceiling fan 2 fit together. This can prevent the hanging rod 20 of the ceiling fan 2 from colliding with the inner wall of the first through hole 111 when the ceiling fan 2 is working, thus avoiding noise generation and affecting the user, while also ensuring the working efficiency of the ceiling fan 2.

[0060] In some preferred or alternative embodiments of the present invention, a plurality of parallel second through holes 112 are formed on both sides of the first through hole 111 along its length direction in the heat exchange plate 110. Each second through hole 112 is used for the heat exchange tube 120 to pass through, and the heat exchange tube 120 is used for the refrigerant to flow through.

[0061] Among them, multiple second through holes 112 are arranged parallel to the length direction of the heat exchange plate 110 on one side of the first through hole 111, and multiple second through holes 112 are arranged parallel to the length direction of the heat exchange plate 110 on the other side of the first through hole 111. By avoiding the first through hole 111 when designing the second through holes 112, interference between the heat exchange tube 120 and the hanging rod 20 of the ceiling fan 2 can be avoided when the ceiling fan 2 is used in conjunction with the plate heat exchanger 100, thus ensuring that the plate heat exchanger 100 and the ceiling fan 2 work well together.

[0062] In some preferred or alternative embodiments of the present invention, the second through hole 112 of the heat exchange plate 110 and the heat exchange tube 120 are adapted in shape.

[0063] The second through hole 112 of the heat exchange plate 110 and the heat exchange tube 120 are adapted to each other, so that the heat exchange tube 120 can be smoothly inserted into the second through hole 112 of the heat exchange plate 110.

[0064] In some preferred or alternative embodiments of the present invention, the second through hole 112 of the heat exchange plate 110 is a columnar through hole.

[0065] In some preferred or alternative embodiments of the present invention, the second through hole 112 of the heat exchange plate 110 is a cylindrical through hole.

[0066] In practical applications, the shape of the second through hole 112 of the heat exchange plate 110 can be determined according to the shape of the heat exchange tube 120, and this utility model does not impose too many restrictions on it.

[0067] In some preferred or alternative embodiments of the present invention, ten parallel second through holes 112 are formed on both sides of the first through hole 111 along its length direction in the heat exchange plate 110.

[0068] The heat exchange plate 110 has ten parallel second through holes 112 arranged on one side of the first through hole 111 along its length direction, and ten parallel second through holes 112 arranged on the other side of the first through hole 111 along its length direction.

[0069] The number of second through holes 112 can be determined according to actual needs, and this utility model does not impose too many restrictions on this.

[0070] Figure 3 This is a schematic structural block diagram of an air conditioner indoor unit according to an embodiment of the present utility model.

[0071] See Figure 3 As shown, based on the same inventive concept, this utility model also proposes an air conditioner indoor unit 10, which includes the plate heat exchanger 100 as in any of the above embodiments.

[0072] Except for the plate heat exchanger 400, the other parts of the indoor air conditioner 10 can be installed in the ceiling, so there is no need to leave a place in the room to place the indoor air conditioner 10, which greatly saves indoor space and improves the user experience.

[0073] Other components of the indoor unit 10 of the air conditioner may include temperature sensors (pipe temperature and ambient temperature), a control board, a drip tray and water pipes, and a casing. The indoor unit is equipped with temperature sensors that measure the pipe temperature and the room temperature. During heating, the system will not start blowing air until the pipe temperature reaches a certain level, preventing the blowing of cold air. When the temperature is too high, it can automatically shut off the air conditioner to protect it. The indoor temperature sensor can automatically control the room temperature based on the set temperature. The control board controls the operation of the indoor unit, managing various aspects of the air conditioner's operation to ensure its proper and normal functioning. The drip tray and water pipes are necessary because condensation occurs in the indoor unit during cooling. If this condensation is not handled properly, it will drip into the room, affecting users. Therefore, a drip tray and water pipes are designed inside the air conditioner to collect and drain the condensation outdoors. The casing primarily protects the internal air conditioning components from dirt and also serves a decorative purpose; all electrical appliances require casing protection. The air filter is a screen that filters out the vast majority of dust and bacteria from the air, keeping the air entering the room clean.

[0074] Figure 4 This is a schematic structural block diagram of an air conditioner according to an embodiment of the present utility model.

[0075] See Figure 4 As shown, based on the same inventive concept, this utility model also proposes an air conditioner, which includes the indoor unit 10 of the air conditioner as in any of the above embodiments.

[0076] In addition to the indoor unit 10, the air conditioner 1 also includes the outdoor unit.

[0077] An air conditioner outdoor unit includes: a condenser (evaporator), temperature sensors (pipe temperature, ambient temperature, compressor temperature), a compressor, a four-way valve, and a control board. The outdoor unit has a condenser / evaporator device, which functions as a condenser in summer to exhaust hot air from the room to the outside, and as an evaporator in winter to absorb heat from the outside and blow it into the room. Temperature sensors (pipe temperature, ambient temperature, compressor temperature): These sensors measure the outside temperature. When the outside temperature is below a certain level, the system will defrost. Overheat protection will activate when the compressor or pipe temperature is too high. Compressor: The air conditioner compressor compresses and drives the refrigerant during cooling or heating. It is usually installed inside the outdoor unit, drawing refrigerant from the low-pressure area, compressing it, and transporting it to the high-pressure area for cooling and condensation. The four-way valve is a control valve with four ports. It is an indispensable component of the air conditioner; the switching between cooling and heating is achieved by adjusting the four-way valve. The control board controls various circuits of the outdoor unit and the working status of the air conditioner, as well as the operating circuits of the outdoor and indoor units.

[0078] This utility model proposes a plate heat exchanger 100, an indoor air conditioning unit 10, and an air conditioner 1. The plate heat exchanger 100 is an indoor air conditioning unit located outside the unit. It includes a heat exchange plate 110 with a first through hole 111 along its thickness for the hanging rod 20 of a ceiling fan 2 to pass through. This allows the plate heat exchanger 100 to exchange heat with air agitated by the fan head 30 near the plate heat exchanger 100. Based on the technical solution proposed in this utility model, the ceiling fan 2 can cooperate with the plate heat exchanger by passing its hanging rod 20 through the first through hole 111 on the heat exchange plate 110. The ceiling fan 2 functions similarly to the blower in the indoor air conditioning unit, eliminating the need for a fan and guide plate in the indoor air conditioning unit, thus reducing its cost. Furthermore, the indoor air conditioning unit does not need to be installed indoors, saving space.

[0079] Furthermore, room heat exchange is achieved by using the ceiling fan 2 in conjunction with the plate heat exchanger 100. The fan of the ceiling fan 2 is larger than that of the air conditioner indoor unit, and its coverage area is wider, thus eliminating dead corners in the whole room. When the ceiling fan 2 is working, the room air is stirred by the ceiling fan 2, and the air with higher temperature rises and the air with lower temperature sinks, and the whole room is in a continuous circulation. At this time, the plate heat exchanger 100 is in the continuously moving indoor air, so it can exchange heat with the indoor air, thereby achieving rapid cooling or heating of the room and rapid temperature change throughout the room.

[0080] Furthermore, the ceiling fan 2 is used in conjunction with the plate heat exchanger 100 to achieve room heat exchange. The area of ​​the plate heat exchanger 100 can be designed arbitrarily according to the size of the room space, thereby meeting the actual needs of users and improving the user experience.

[0081] Furthermore, the heat exchange plate 110 in this utility model is rectangular, and the first through hole 111 is located in the middle of the heat exchange plate 110, so that almost all the air stirred by the ceiling fan 2 to the vicinity of the plate heat exchanger 100 can be heat exchanged per unit time, thereby improving the heat exchange efficiency of the plate heat exchanger 100 and realizing rapid cooling or heating of the room.

[0082] Furthermore, in this invention, the first through hole 111 of the heat exchange plate 110 and the hanging rod 20 of the ceiling fan 2 are adapted in shape. After the hanging rod 20 of the ceiling fan 2 is assembled in the first through hole 111 of the heat exchange plate 110, the hole wall of the first through hole 111 of the heat exchange plate 110 and the rod wall of the hanging rod 20 of the ceiling fan 2 fit together. This can prevent the hanging rod 20 of the ceiling fan 2 from colliding with the inner wall of the first through hole 111 when the ceiling fan 2 is working, thus avoiding noise generation and affecting the user. At the same time, it also ensures the working efficiency of the ceiling fan 2.

[0083] Furthermore, in this invention, the heat exchange plate 110 has multiple parallel second through holes 112 formed on both sides of the first through hole 111 along its length direction. Each second through hole 112 is used for the heat exchange tube 120 to pass through, and the heat exchange tube 120 is used for the refrigerant to flow through. The multiple second through holes 112 are arranged parallel to each other on one side of the first through hole 111 along the length direction of the heat exchange plate 110, and on the other side of the first through hole 111 along the length direction of the heat exchange plate 110. By designing the second through holes 112 to avoid the first through hole 111, interference between the heat exchange tube 120 and the hanging rod 20 of the ceiling fan 2 can be avoided when the ceiling fan 2 is used in conjunction with the plate heat exchanger 100, ensuring good cooperation between the plate heat exchanger 100 and the ceiling fan 2.

[0084] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
