Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to an integrated range hood system. Background Technology

[0002] Kitchens typically don't have a fresh air system, mainly because in winter, when cooking, the outdoor temperature is usually lower than the indoor temperature. Directly introducing outdoor air would cause the indoor temperature to drop, leading to discomfort. Kitchen air conditioners with fresh air functions require additional electric auxiliary heating to heat the fresh air, resulting in high energy consumption.

[0003] A phase change heat exchange component is employed, comprising an evaporator, a condenser, and a circulation pipe connecting the evaporator and the condenser, with a height difference between them. The evaporator utilizes the heat from the gas in the exhaust pipe to convert the refrigerant from a liquid to a gaseous state, reducing the refrigerant's density, and then it enters the condenser through the circulation pipe. In the condenser, the refrigerant converts from a gaseous state to a liquid state, releasing heat and thus heating the surrounding air. Simultaneously, the refrigerant's density increases, and it re-enters the evaporator through the circulation pipe, thus completing the cycle.

[0004] The problem is that when fresh air enters the equipment, the airflow is not smooth, resulting in poor heat exchange efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated range hood system that can, to some extent, solve the technical problem in related technologies where the fresh air entering the device has poor airflow and thus results in poor heat exchange efficiency.

[0006] This invention provides an integrated range hood system, comprising: a housing having a fume extraction channel, wherein the housing has a fume inlet and a fume outlet, both of which are in fluid communication with the fume extraction channel; the housing also has a heat exchange chamber, wherein the housing has a fresh air inlet for communication with the outside and an air outlet for communication with the inside, both of which are in fluid communication with the heat exchange chamber; the heat exchange chamber includes a first region and a second region, wherein a phase change evaporator is disposed in the first region and a second region is disposed in the second region. The system includes: a phase change condenser; a blower fan located in the second region with its outlet connected to the air outlet; a fume extraction duct located in the first region and not connected to the heat exchange chamber; the phase change condenser being higher than the phase change evaporator in the height direction of the housing; and a baffle plate located in the second region, the baffle plate being arranged on the airflow path between the fresh air inlet and the air outlet, and at least a portion of the baffle plate being arranged to move up and down in the height direction of the housing; and a drive mechanism with its power output end connected to the baffle plate.

[0007] Furthermore, the air outlet is located on the front side of the housing, and the fresh air inlet is located on the top of the housing; the guide plate extends forward and backward, with the rear end of the guide plate being the windward end, and the front end of the guide plate being opposite to the air inlet of the air supply fan; the guide plate has an arc-shaped structure that curves from top to bottom and forward; the drive mechanism is connected to the rear end of the guide plate to drive the guide plate to swing.

[0008] Furthermore, the integrated range hood system also includes a fixed bracket, and the driving mechanism is a motor, which is fixed on the fixed bracket and is connected to the guide plate via a rotating shaft.

[0009] Furthermore, there are multiple guide vanes and multiple driving mechanisms, and the multiple driving mechanisms are connected to the multiple guide vanes in a one-to-one transmission connection to drive the multiple guide vanes to swing respectively.

[0010] Furthermore, there are two guide vanes and two drive mechanisms; the two guide vanes are arranged side by side in the width direction of the housing.

[0011] Furthermore, one of the two air deflectors is positioned close to the fresh air inlet.

[0012] Furthermore, the rotation angle range of the guide plate is 0°-75°.

[0013] Furthermore, the guide plate is provided with a first flow cavity and a second flow cavity. The first flow cavity is connected between the condenser outlet and the evaporator inlet, and the second flow cavity is connected between the evaporator outlet and the condenser inlet, so as to realize the circulation of refrigerant between the phase change evaporator and the phase change condenser.

[0014] Furthermore, in the thickness direction of the guide plate, the first flow cavity and the second flow cavity are arranged side by side.

[0015] Furthermore, the ratio of the thickness of the first flow cavity to the thickness of the second flow cavity is in the range of 2:1 to 4:3.

[0016] The integrated range hood system provided by this invention can achieve at least the following beneficial effects:

[0017] The drive mechanism can move the guide vane, causing at least a portion of it to move up and down along the height of the housing. This changes the position of the guide vane in the second region, alters its position relative to the phase change condenser, and thus changes the direction of the fresh air flow, altering the airflow path. Therefore, the integrated range hood system provided in this embodiment can adjust the position of the guide vane in the second region according to different requirements, allowing the fresh air to flow in a direction that meets the needs. This enables more precise adjustment of the flow field, resulting in a more uniform flow and smoother fresh air flow. It also improves the heat exchange effect between the fresh air and the phase change condenser 5, as well as the heat exchange effect between the phase change evaporator 4 and the gas in the exhaust duct 2, thereby increasing waste heat utilization.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0041] It should be noted that in the embodiments of the present invention, "front" refers to the direction closer to the interior, and "rear" is the opposite direction to "front".

[0042] like Figures 1 to 3As shown, the present invention provides an integrated range hood system, comprising: a housing 1 having a fume extraction channel 2, wherein the housing 1 has a fume inlet and a fume outlet, both of which are in fluid communication with the fume extraction channel 2; the housing 1 also has a heat exchange chamber, wherein the housing 1 has a fresh air inlet 13 for communicating with the outside and an air outlet for communicating with the inside, both of which are in fluid communication with the heat exchange chamber; the heat exchange chamber includes a first region 11 and a second region 12 that are independent of each other, wherein a phase change evaporator 3 is disposed in the first region 11 and the second region 12... The device includes a phase change condenser 4; a blower 8 located in the second area 12 with its outlet connected to the air supply port; an oil fume extraction duct 2 located in the first area 11 and not connected to the heat exchange chamber; the phase change condenser 4 being higher than the phase change evaporator 3 in the height direction of the housing 1; and a baffle plate 5 located in the second area 12, arranged on the airflow path between the fresh air inlet 13 and the air supply port, with at least a portion of the baffle plate 5 arranged to move up and down in the height direction of the housing 1; and a drive mechanism with its power output end connected to the baffle plate 5.

[0043] In this embodiment, the refrigerant changes from a liquid state to a gaseous state in the phase change evaporator 3, and the density of the refrigerant decreases, flowing towards the phase change condenser 4 located at a relatively high position; the refrigerant changes from a gaseous state to a liquid state in the phase change condenser 4, and the density of the refrigerant increases, flowing towards the phase change evaporator 3 located at a relatively low position, and the refrigerant circulates in this way.

[0044] The fume extraction duct 2 is located within the first zone 11. Kitchen fumes enter the outer casing through the fume inlet, then into the fume extraction duct 2, and finally exit through the fume outlet into the kitchen fume duct hole. The high temperature of the fumes transfers heat to the air in the first zone 11, raising its temperature. This increased temperature difference between the heated air and the refrigerant in the phase change evaporator 3 allows for a faster phase change of the refrigerant, improving its heat exchange efficiency. This, in turn, accelerates refrigerant circulation, further enhancing the heat exchange efficiency of the phase change condenser 4 and ultimately improving the heat exchange efficiency of the fresh air, resulting in better warming of the fresh air. Furthermore, the residual heat from the fumes is utilized and recovered, saving energy.

[0045] Powered by the air supply fan 8, fresh air enters the second zone 12 of the heat exchange chamber through the fresh air inlet 13. As the fresh air passes through the phase change condenser 4, it exchanges heat with the refrigerant within the condenser, thus heating the air. When the heated fresh air reaches the guide plate 5, the guide plate 5 directs the airflow, concentrating it towards the air outlet. This ensures the fresh air enters the room in a specific direction, preventing it from becoming scattered and disorderly. By adjusting the airflow direction, more efficient air circulation and distribution can be achieved, improving airflow smoothness and uniformity, thereby increasing heat recovery efficiency and heat exchange effect. This also prevents a large temperature difference between the incoming air and the room temperature, improving the user experience. Furthermore, the shape and position of the guide plate 5 allow for control of airflow speed and adjustment of the fresh air velocity, preventing excessively fast or slow airflow. The guide plate 5 also optimizes airflow and reduces noise generation.

[0046] The drive mechanism can move the guide plate 5, causing at least a portion of it to move up and down along the height of the housing 1. This changes the position of the guide plate 5 within the second region 12, alters its position relative to the phase change condenser 4, and thus changes the direction of airflow from the guide plate 5 to the fresh air, altering the airflow path. Therefore, the integrated range hood system provided in this embodiment can adjust the position of the guide plate 5 within the second region 12 according to different requirements, allowing the fresh air to flow in a direction that meets the needs. This enables more precise adjustment of the flow field, resulting in a more uniform flow, smoother fresh air flow, improved heat exchange between the fresh air and the phase change condenser 4, and also improved heat exchange between the phase change evaporator 3 and the gas in the exhaust duct, thereby increasing waste heat utilization.

[0047] Within the first area 11, a partition can be installed to create a passageway, forming the fume extraction passageway 2. As an optional solution, such as... Figure 1 As shown, the integrated range hood system also includes: a circulation pipe, which is set inside the heat exchange chamber. The circulation pipe is hollow inside to form a fume extraction channel 2. The circulation pipe facilitates assembly.

[0048] Specifically, the upper part of the shell 1 has a heat exchange chamber, the lower part of the shell 1 has a smoke exhaust chamber, and an oil fume inlet is opened on the lower front side of the shell 1. The oil fume inlet is connected to the smoke exhaust chamber. One end of the oil fume suction channel is connected to the smoke exhaust chamber, and the other end is connected to the oil fume outlet. An oil fume outlet can be opened on the top of the shell 1.

[0049] A first baffle can be provided inside the housing 1 to divide the inner cavity of the housing 1 into a lower exhaust chamber and an upper heat exchange chamber. A second baffle can be provided inside the heat exchange chamber to divide the heat exchange chamber into a first region 11 and a second region 12 that are independent of each other. Alternatively, the housing 1 includes an upper shell and a lower shell that are connected to each other. The inner cavity of the upper shell forms a heat exchange chamber, and the inner cavity of the lower shell forms an exhaust chamber. A baffle can be provided inside the inner cavity of the upper shell to divide the inner cavity into a first region 11 and a second region 12.

[0050] As an optional solution, the air outlet is located on the front side of the housing 1 (optionally, the air outlet is located on the upper part of the housing 1), and the fresh air inlet 13 is located on the top of the housing 1. This facilitates the connection of the fresh air inlet 13 to an external pipe for communication with the outside. Furthermore, the fresh air inlet 13 is located on the top of the housing 1, which allows the external pipe to be located on the top of the housing 1, thus avoiding the occupation of the thickness or width space of the integrated range hood system.

[0051] The guide vane 5 extends forward and backward, with its rear end being the windward end 52, which is close to the phase change condenser 4. The front end of the guide vane 5 is opposite to the air inlet of the supply fan 8. This alignment of the guide vane 5's front end with the supply fan 8's air inlet allows for direct guidance of fresh air to the supply fan 8, enabling it to deliver fresh air into the room more quickly and improving indoor air quality control efficiency.

[0052] Based on the above embodiments, the guide plate 5 can be a straight plate, which is inclined relative to the vertical direction. The rear end of the straight plate is located below the phase change condenser 4, and the front end of the straight plate extends towards the blower 8. It should be noted that a straight plate means that the outline of the side of the guide plate 5 is a straight line, and the plate surface of the guide plate 5 (the two surfaces located between the two side surfaces) can be wavy, sawtooth, etc.

[0053] As an alternative, the windward end 52 of the guide plate 5 is set higher than the front end of the guide plate 5, and the guide plate 5 is set in a rearward convex arc shape (for example, the guide plate 5 is set in an arc shape convex away from the phase change condenser 4). The guide plate 5 is set in an arc shape (the side profile of the guide plate 5 and the plate surface of the guide plate 5 are both set in an arc shape). This can make the fresh air flow smoother and can better adjust the flow speed of the fresh air, further improve the smoothness and uniformity of airflow, and thus further improve the heat recovery efficiency.

[0054] As an alternative, the guide plate 5 can be a flat plate, meaning its thickness is much smaller than its length, which facilitates airflow guidance and reduces the space it occupies. The depth direction of the flow channel can be the same as the thickness direction of the guide plate 5.

[0055] Based on the above embodiments, the driving mechanism can be an electric telescopic rod or a linear telescopic mechanism such as a linear motor 6. The power output end of the driving mechanism is connected to the guide plate 5 to drive the guide plate 5 to move up and down in the height direction of the housing 1, thereby adjusting the position of the guide plate 5.

[0056] As an alternative, such as Figures 1 to 3 As shown, the drive mechanism is connected to the windward end 52 of the guide plate 5 to drive the guide plate 5 to swing, thereby causing other parts of the guide plate 5 (e.g., the middle and front ends) to move up and down in the height direction of the housing 1. The guide plate 5 continuously changes its angle during the swinging process. In this embodiment, the rear end of the guide plate 5 is rotated by the drive mechanism to realize the swinging of the guide plate 5, thereby enabling a part of the guide plate 5 to move up and down in the height direction of the housing 1, which makes the structure simple and occupies less space.

[0057] Specifically, such as Figure 3 As shown, the integrated range hood system also includes a fixed bracket 7 (the fixed bracket 7 is fixed inside the heat exchange chamber and can be fixed to the inner wall of the heat exchange chamber through a connector), and the driving mechanism is a motor 6. The motor 6 is fixed on the fixed bracket 7. The motor 6 is connected to the guide plate 5 through a rotating shaft. The motor 6 drives the guide plate 5 to rotate to adjust the angle of the guide plate 5 relative to the fixed bracket 7.

[0058] Based on the above embodiments, the number of guide plates 5 can be one. When the number of guide plates 5 is one, the guide plate 5 can cover the phase change condenser 4 by projecting onto the plane where the phase change condenser 4 is located.

[0059] As an alternative, such as Figures 1 to 3 As shown, there are multiple guide vanes 5, and multiple drive mechanisms are connected to multiple guide vanes 5 in a one-to-one transmission connection to drive the multiple guide vanes 5 to swing.

[0060] In this embodiment, each guide vane 5 is equipped with a drive mechanism, allowing multiple drive mechanisms to drive multiple guide vanes 5 to rotate simultaneously. These multiple drive mechanisms can adjust multiple guide vanes 5 to the same angle. Alternatively, the multiple drive mechanisms can operate independently, adjusting multiple guide vanes 5 to different angles, or adjusting some guide vanes 5 to the same angle, etc. In other words, each guide vane 5 can be adjusted to a corresponding angle as needed. This configuration allows for more gas flow paths when needed, dividing the fresh air into multiple airflows, reducing airflow resistance, improving airflow efficiency, and making the fresh air flow field more uniform. This results in a larger volume of fresh air entering the phase change condenser 4 with a more uniform cross-sectional velocity, further improving waste heat recovery efficiency. It also allows for more effective and even distribution of cold or hot air to all corners of the heat exchanger.

[0061] Understandably, multiple deflectors 5 can divide the fresh air into multiple airflows, and the overall flow of the fresh air still has a certain directionality, rather than being scattered and disorderly.

[0062] The number of guide vanes 5 can be multiple (e.g., three, four, or five).

[0063] As an alternative, there are two guide vanes 5 and two drive mechanisms; in the width direction of the housing 1, the two guide vanes 5 are arranged side by side, and the projection of the two side by side guide vanes 5 on the plane where the phase change condenser 4 is located can cover the phase change condenser 4.

[0064] Each baffle 5 can be adjusted to the corresponding angle as needed. For example, the integrated range hood system includes a control system and a remote control. The control system stores the correspondence between the fresh air volume and the angle of the baffle 5 in advance. The user can select a fresh air volume through the remote control. The control system controls the drive mechanism to work according to the user's selection, thereby adjusting the angle of the baffle 5, etc.

[0065] The adjustment positions of the two guide vanes 5 can be set as needed.

[0066] Optional, such as Figure 2 As shown, along the width direction of the housing 1, the first region 11 and the second region 12 are arranged side by side. The front end of the guide plate 5 closer to the first region 11 is closer to the fresh air inlet 13 than the front end of the guide plate 5 farther from the first region 11. That is, the front end of the guide plate 5 closer to the first region 11 is higher than the front end of the guide plate 5 farther from the first region 11.

[0067] In this embodiment, the guide plate 5 closer to the first region 11 is the first guide plate 5, and the guide plate 5 farther away from the first region 11 is the second guide plate 5. The first region 11 is equipped with a fume extraction channel 2. The high temperature of the fumes can transfer heat to the first region 11, resulting in a higher temperature in the first region 11. When the fresh airflow guided by the first guide plate 5 approaches the first region 11, it will be subjected to heat transfer from the first region 11. This portion of the fresh airflow will also be heated further after passing through the phase change condenser 4. The front end of the first guide plate 5 is closer to the fresh air inlet 13 than the front end of the second guide plate 5. Therefore, the first guide plate 5 is closer to the phase change condenser 4, which can accelerate the flow rate. This allows the fresh air corresponding to the first guide plate 5 to pass through the phase change condenser 4 faster (compared to the fresh airflow corresponding to the second guide plate 5), resulting in less heat exchange for this portion of the fresh airflow passing through the phase change condenser 4. Conversely, the second guide plate 5 is positioned further away from the phase change condenser 4, resulting in a slightly slower flow of fresh air. This means the fresh airflow corresponding to the second guide plate 5 passes through the phase change condenser 4 at a relatively slower speed, allowing this portion of the fresh airflow to receive more heat exchange. Although the fresh air guided by the first guide plate 5 receives less heat exchange through the phase change condenser 4, it can receive heat transferred from the first region 11 after entering the second region 12. This reduces the temperature difference between the fresh air and the air guided by the second guide plate 5, thus maintaining a uniform temperature for both streams of fresh air.

[0068] Based on the above embodiments, the rotation angle range of the guide vane 5 is further 0°-75°, for example: 0°, 10°, 15°, 20°, 25°, 30°, 40°, 50°, 60°, 65°, 70°, or 80°. When there are multiple guide vanes 5, each guide vane 5 can rotate within the above range.

[0069] In the thickness direction of the shell 1, the rear end of the guide plate 5 can be opposite to the middle of the phase change condenser 4 to form a flow channel on the front and rear sides of the guide plate 5 respectively. In this embodiment, the rear end of the guide plate 5 is arranged opposite to the middle of the phase change condenser 4. The guide plate 5 can divide the gas passing through the phase change condenser 4 into two paths, one located on the front side of the guide plate 5 and the other located on the rear side of the guide plate 5. The guide plate 5 is flat, that is, the thickness of the guide plate 5 is less than the length and width of the guide plate 5. This arrangement can reduce the velocity difference between the two airflow paths, making the velocities of the two airflow paths as consistent as possible, thereby ensuring the uniformity of fresh air heat exchange.

[0070] As an alternative, such as Figure 2 As shown, in the thickness direction of the housing 1, the rear end of the guide plate 5 is opposite to the rear side of the phase change condenser 4. In this embodiment, after the fresh air reaches the guide plate 5, it is guided through the upper plate surface 55 (or the upper plate surface 55) of the guide plate 5.

[0071] like Figure 4 As shown, based on the above embodiment, the guide plate 5 is further provided with a guide port 51 to allow gas to flow from one side of the same guide plate 5 to the opposite side of the guide plate 5. Both the fresh air inlet 13 and the air outlet are in fluid communication with the heat exchange chamber and form a fresh air flow channel. The fresh air flow channel includes a first flow section 58 and a second flow section 59 whose flow directions intersect. The fresh air flow channel bends from the first flow section 58 through the guide port 51 to form the second flow section 59.

[0072] In this embodiment, a guide port 51 is provided on the guide plate 5, that is, an opening is made on the guide plate 5, so that at least part of the fresh air can pass through the guide port 51. This arrangement can increase the flow path of the fresh air and make the fresh air flow field more uniform. Especially when the angles of two adjacent guide plates 5 are different, relatively speaking, part of the fresh air flow of the guide plate 5 closer to the fresh air inlet 13 can pass through the guide port 51 and mix with part of the fresh air flow guided by the guide plate 5 below before moving. The turning and mixing of the fresh air flow cause air agitation, further improving the uniformity of the fresh air.

[0073] The number of guide ports 51 can be one, two, three or four, etc. When there are multiple guide ports 51, within a certain range, the multiple guide ports 51 can be spaced apart along the length direction of the guide plate 5, or spaced apart along the width direction of the guide plate 5, or the multiple guide ports 51 can be arranged in a crisscross pattern.

[0074] The guide port 51 can be set on the guide plate 5 as needed. For example, in the extension direction of the guide plate 5, the rear end (i.e. the windward end) of the guide plate 5 is rotatably connected to the fixed bracket 7. The guide port 51 extends from the end close to the bracket to the end far away from the fixed bracket 7, and the guide plate 5 is arc-shaped, covering the concave part of the guide plate 5, which can make the fresh air diversion smoother.

[0075] Based on the above embodiments, the fresh air flow channel further includes a third flow section 510 whose flow direction intersects with both the flow direction of the first flow section 58 and the flow direction of the second flow section 59; in the width direction of the guide plate 5, the guide port 51 includes an air-guiding sidewall 511 disposed opposite to it; in the extension direction of the guide plate 5, the guide port 51 includes a flow-dividing sidewall 512 located on the lower side; the third flow section 510 is located on the upper side of the guide plate 5 and downstream of the flow-dividing sidewall 512; the second flow section 59 is located on the lower side of the guide plate 5; and the third flow section 510 is located on the upper side of the guide plate 5.

[0076] In this embodiment, as the fresh airflow flows along the guide port 51, the fresh airflow located in the middle of the guide port 51 can bend and enter the second flow section 59; the fresh airflow near the air intake sidewall 511 of the guide port 51 can flow along the air intake sidewall 511 to the diversion sidewall 512. After impacting the diversion sidewall 512, this part of the fresh airflow bends upward and enters the third flow section 510, while the other part bends and enters the second flow section 59; and a part of the fresh airflow directly impacts the diversion sidewall 512, which allows this part of the fresh airflow to bend upward and enter the third flow section 510, while the other part bends and enters the second flow section 59. Of course, the fresh airflow that does not have time to bend through the guide port 51 can directly enter the third flow section 510 from the first flow section 58. In this embodiment, the fresh airflow has at least three flow areas along the guide plate 5, which can further improve the smoothness and uniformity of the fresh airflow, thereby further improving the heat exchange efficiency; moreover, part of the fresh airflow can be bent multiple times, and the fresh airflow can be further agitated, thereby making the temperature of the fresh air more uniform.

[0077] Preferably, the diversion sidewall 512 is arranged at an angle, and the upper edge of the diversion sidewall 512 is closer to the front end of the guide plate 5 than the lower edge of the diversion sidewall 512. This arrangement can increase the contact area with the fresh air flow, receive more fresh air, and is more conducive to diverting the fresh air flow.

[0078] The flat-shaped baffle 5 can also prevent a large difference in airflow velocity between the second flow section 59 and the third flow section 510, which is conducive to keeping the airflow velocities of the two flow paths consistent.

[0079] like Figure 4 As shown, based on any of the above embodiments, the guide plate 5 is further provided with a first flow cavity 53 and a second flow cavity 54. The first flow cavity 53 is connected between the condenser outlet and the evaporator inlet, and the second flow cavity 54 is connected between the evaporator outlet and the condenser inlet, so as to realize the circulation of refrigerant between the phase change evaporator 3 and the phase change condenser 4.

[0080] Specifically, the first flow chamber 53 connects the outlet of the phase change condenser 4 and the inlet of the phase change evaporator 3, and the second flow chamber 54 connects the inlet of the phase change condenser 4 and the outlet of the phase change evaporator 3. Liquid refrigerant enters the first flow chamber 53 from the outlet of the phase change condenser 4, and then enters the phase change evaporator 3 through the inlet of the phase change evaporator 3. After absorbing heat and converting to gas within the phase change evaporator 3, the gaseous refrigerant enters the second flow chamber 54 through the outlet of the phase change evaporator 3, and then enters the phase change condenser 4 through the inlet of the phase change condenser 4, thus achieving refrigerant circulation. In this embodiment, the guide plate 5 not only guides the gas flow but also facilitates the circulation of refrigerant, replacing part of the refrigerant circulation piping and reducing the piping within the heat exchange chamber. This results in a simple and compact refrigeration circulation structure between the phase change evaporator 3 and the phase change condenser 4.

[0081] It should be noted that the first flow chamber 53 is connected to the phase change condenser 4 and the phase change evaporator 3 respectively through the flexible tube, and the second flow chamber 54 is connected to the phase change condenser 4 and the phase change evaporator 3 respectively, so as to facilitate the rotation of the guide plate 5.

[0082] It is understandable that since the guide plate 5 is located in the second region 12 and the phase change evaporator 3 is located in the first region 11, the pipeline between the guide plate 5 and the phase change evaporator 3 needs to pass through the wall between the first region 11 and the second region 12.

[0083] The guide plate 5 can be hollow, and a partition is provided in the inner cavity of the guide plate 5 to divide the inner cavity of the guide plate 5 into a first flow cavity 53 and a second flow cavity 54.

[0084] The first flow cavity 53 and the second flow cavity 54 can be arranged side by side in the width direction of the guide plate 5 (the width direction of the guide plate 5 is consistent with the width direction of the housing 1).

[0085] As an alternative, such as Figure 4 As shown, in the thickness direction of the guide plate 5, the first flow cavity 53 and the second flow cavity 54 are arranged side by side, or the first flow cavity 53 and the second flow cavity 54 are arranged vertically. With this arrangement, the area of ​​the plate surface of the guide plate 5 corresponding to the first flow cavity 53 and the area of ​​the plate surface corresponding to the second flow cavity 54 can both reach the maximum, thereby maximizing the effective heat exchange area between the airflow and the refrigerant in the first heat exchange cavity and / or maximizing the effective heat exchange area between the airflow and the refrigerant in the second heat exchange cavity.

[0086] For example: The first flow cavity 53 is located above the second flow cavity 54. When, in the thickness direction of the housing 1, the rear end of the flow guide plate 5 is opposite to the rear side of the phase change condenser 4, when the air flow passes through the upper plate surface 55 of the flow guide plate 5 (when the flow guide plate 5 is in an inclined state, the upper plate surface 55 of the flow guide plate 5 is also its front plate surface), the gas can exchange heat with the liquid refrigerant in the first flow cavity 53 on the upper plate surface 55 of the flow guide plate 5, further reducing the temperature of the liquid refrigerant, thereby increasing the temperature difference between the liquid refrigerant and the fresh air, improving the heat exchange effect, and further increasing the temperature of the fresh air. When, in the thickness direction of the housing 1, air flow channels are formed on both the front and rear sides of the flow guide plate 5, the fresh air flow on the upper side exchanges heat with the liquid refrigerant in the first flow cavity 53, and the fresh air flow on the lower side exchanges heat with the gaseous refrigerant in the second flow cavity 54, and the temperature of both paths of fresh air can be increased.

[0087] Among them, the cross-sectional area of the first flow cavity 53 and the cross-sectional area of the second flow cavity 54 can be the same. The cross-sectional area of the first flow cavity 53 and the cross-sectional area of the second flow cavity 54 can be the same or different. For example: The ratio range of the thickness of the first flow cavity 53 to the thickness of the second flow cavity 54 is: 2:1 - 4:3 (for example: 4:3, 3:2, 9:5 or 2:1), etc.

[0088] A first through hole is provided on the upper layer of the flow guide plate 5, the first through hole penetrates through the first flow cavity 53, a second through hole is provided on the lower layer of the flow guide plate 5, the second through hole penetrates through the second flow cavity 54, and the first through hole and the second through hole are connected, thereby forming a guiding port 51 through which the fresh air flow can pass.

[0089] The first through hole can be set in a shape such as a circle, an ellipse, a kidney shape, a triangle, or a pentagon, etc. The second through hole can also be set in a shape such as a circle, an ellipse, a kidney shape, a triangle, or a pentagon, etc. The shapes of the first through hole and the second through hole can be different. Optionally, the shapes of the first through hole and the second through hole are the same, which is convenient for processing.

[0090] As an optional solution, the first through hole is set in a quadrilateral shape so that the first flow cavity 53 is set in a "hui" character shape, and the second through hole is set in a quadrilateral shape so that the second flow cavity 54 is set in a "hui" character shape, which is convenient for processing.

[0091] Among them, the first through hole and the second through hole can be partially oppositely arranged, that is, at least part of the fresh air flow entering the first through hole still needs to turn and then enter the second through hole.

[0092] As an optional solution, the first through hole and the second through hole are arranged正对 (I'm not sure what this "正对" exactly means here, it might be a misspelling or a specific term. If it means "opposite and aligned", it can be translated as "opposite and aligned") so as to facilitate the processing of the flow guide plate 5.

[0093] Such as Figures 2 to 5As shown, based on the above embodiment, further, in the thickness direction of the guide plate 5, at least on the upper plate surface 55 of the guide plate 5, fins 57 are provided. The fins 57 can realize airflow turbulence, making the gas temperature more uniform and improving the heat exchange efficiency.

[0094] Alternatively, fins 57 can be provided only on the upper plate surface 55, or on both the upper plate surface 55 and the lower plate surface 56.

[0095] It should be noted that a charging port 513 is provided on the guide plate 5. The charging port 513 can be connected to the first flow chamber 53, the second flow chamber 54, or both the first and second flow chambers 53 and 54. Refrigerant can be charged through the charging port 513. Of course, if necessary, the refrigerant in the phase change condenser 4 and the phase change evaporator 3 can also be discharged.

[0096] The fin 57 can be a raised structure, such as dotted protrusions or striped protrusions, or a recessed structure, such as dotted recesses or striped recesses.

[0097] Based on some optional technical solutions, a return air inlet can be further provided at the top of the housing 1. The return air inlet is used to connect with the indoor environment. The fresh air inlet 13 and the return air inlet can be connected as a whole, that is, an opening is opened at the top of the housing 1, part of which is the fresh air inlet 13 and the other part is the return air inlet. An air intake component 9 can be provided above, below, or inside the opening. The projection of the air intake component 9 on the plane of the opening can cover the opening. The air intake component 9 includes an air intake housing 91, on which there are independent fresh air inlet section 92 and return air inlet section 93. The fresh air inlet section 92 corresponds to the fresh air inlet 13, and the return air inlet section 93 corresponds to the return air inlet. Both the return air inlet section 93 and the fresh air inlet section 92 are provided with filters 94. The fresh air inlet section 92 is connected to a fresh air pipe 95. The phase change condenser 4 can be installed in the heat exchange chamber and located downstream of the air inlet assembly 9. The projection of the condenser on the plane where the inlet is located can cover the inlet. The fresh air entering through the fresh air inlet 92 and the return air entering through the return air inlet 93 can both enter the second region 12 through the phase change condenser 4.

[0098] The installation of fresh air inlet 13 and return air inlet allows for the introduction of both fresh outdoor air and indoor air at a relatively higher temperature than the outdoor air. The fresh and return air can be mixed in the first heat exchange chamber before being supplied to the room. This reduces the heating time for the fresh air while still providing a certain amount of fresh air to the room, improving the kitchen's indoor environment. Filter 94 filters both the fresh and return air.

[0099] At least one of the multiple air deflectors 5 corresponds to the fresh air inlet 13 to guide the fresh air flow, and at least another air deflector 5 corresponds to the return air inlet to guide the return air flow. The air deflector 5 corresponding to the fresh air inlet 13 is a fresh air deflector 5, and the air deflector 5 corresponding to the return air inlet is a return air deflector 5. The driving component connected to the fresh air deflector 5 is a fresh air driving component, and the driving component connected to the return air deflector 5 is a return air driving component. The fresh air driving component drives the fresh air deflector 5 to move, and the return air driving component drives the return air deflector 5 to rotate. Thus, by adjusting the angles of the fresh air deflector 5 and the return air deflector 5 according to the required ratio of fresh air to return air, the fresh air and return air can be better mixed, resulting in a more uniform temperature of the air entering the room and improving the user experience.

[0100] Users can select a fresh air volume using a remote control. The control system will then control the drive mechanism to adjust the angles of the fresh air guide plate 5 and the return air guide plate 5 according to the user's selection.

[0101] The system integrates fresh air intake, return air intake, fresh air filtration, and return air filtration into a single unit, resulting in a compact structure that occupies little space.
