[0040] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0041] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0042] Please refer to the following Figure 1-Figure 10 The duct machine 100 according to the embodiment of the present invention is described. The duct machine 100 according to the embodiment of the present invention is, for example, a vertical duct machine.

[0043] like Figure 1-Figure 5 As shown, the duct machine 100 according to the embodiment of the utility model includes a casing 1, a heat exchanger 2, a fan assembly, a germicidal lamp assembly 3 and an electric control box 4.

[0044] The casing 1 is used to be placed vertically on the ground, and the casing 1 is provided with an air inlet and an air outlet, the heat exchanger 2 is arranged in the casing 1, the fan assembly is arranged in the casing 1 and is located on one side of the heat exchanger 2, the fan assembly drives the air to enter the casing 1 from the air inlet, and the air exchanges heat with the heat exchanger 2 to form a heat exchange airflow, and then is driven by the fan assembly to enter the room from the air outlet.

[0045] The casing 1 may have multiple air inlets, for example, one air inlet may be an air inlet for outdoor fresh air, and another air inlet may be an air inlet for indoor air. In addition, the fan assembly may be located on one side of the heat exchanger 2 adjacent to the air outlet.

[0046] In this way, the duct machine 100 can selectively control outdoor fresh air and indoor air to enter the casing 1 through the air inlets through multiple air inlets, and the outdoor fresh air or indoor air can form a heat exchange airflow after heat exchange with the heat exchanger 2, and then be driven by the fan assembly to be introduced into the room from the air outlet, thereby realizing indoor cooling or heating.

[0047] The germicidal lamp assembly 3 is arranged in the housing 1, so that the germicidal lamp assembly 3 is installed during the production process, and an installation position and an interface can be reserved for the germicidal lamp assembly 3 in the housing 1 to facilitate the installation of the germicidal lamp assembly 3. Compared with the prior art, in which the installation of the germicidal lamp and the ballast requires opening a hole in the air duct of the air duct machine on site, the installation operation of the germicidal lamp 301 in the embodiment of the utility model is more time-saving and labor-saving.

[0048] In the embodiment of the utility model, the germicidal lamp assembly 3 includes a germicidal lamp 301 and a ballast 302. The germicidal lamp 301 is arranged in the heat exchanger 2, so that the light emitted by the germicidal lamp 301 can directly irradiate the air around the heat exchanger 2, so that the germicidal lamp 301 can sterilize and disinfect the air around the heat exchanger 2.

[0049] In this way, when the air after heat exchange is driven by the fan assembly to enter the room from the air outlet, it can ensure that the cleanliness of the air entering the room meets the user's requirements, making this product more in line with the user's usage needs, thereby improving the user's usage experience

[0050] The ballast 302 is electrically connected to the germicidal lamp 301, so that the high voltage generated by the ballast 302 can ensure that the germicidal lamp 301 is normally turned on, and can stabilize the current of the germicidal lamp 301, which is beneficial to energy saving of the germicidal lamp 301 and protection of the circuit safety of the germicidal lamp 301.

[0051] The electric control box 4 is spaced apart from the heat exchanger 2, which can ensure that the electric control box 4 is independently arranged in the housing 1 to ensure the working reliability of the electric control box 4. The electric control box 4 is electrically connected to the heat exchanger 2 to control the operation of the heat exchanger 2 and adjust the working state of the heat exchanger 2, so that the duct unit 100 can cool or heat the room.

[0052] The electric control box 4 is electrically connected to the fan assembly, and can control the driving capacity of the fan assembly, so that the air output size and air volume of the duct air conditioner 100 can be adjusted by adjusting the driving force of the fan assembly on the air. Thus, the duct air conditioner 100 can have a flexible adjustable function, and the duct air conditioner 100 of the embodiment of the utility model can meet the use needs of different users.

[0053] In the related art, the germicidal lamp and the duct unit are integrated, and the ballast is installed and removed together when the germicidal lamp is installed and removed. However, compared with the ballast, the service life of the germicidal lamp is shorter and the failure frequency is higher. Therefore, in the prior art, when replacing the germicidal lamp, the ballast needs to be replaced together, and most of the ballasts at this time are in good working order. Such operation will cause unnecessary waste of the ballast, thereby increasing the replacement cost and use cost of the duct unit.

[0054] In the air duct unit 100 of the embodiment of the utility model, the germicidal lamp 301 and the ballast 302 are separately arranged. The germicidal lamp 301 is arranged in the heat exchanger 2, and the ballast 302 is arranged in the electric control box 4. In this way, the germicidal lamp 301 and the ballast 302 in the air duct unit 100 of the embodiment of the utility model can be separately arranged.

[0055] Furthermore, the germicidal lamp 301 in the embodiment of the utility model is connected to the ballast 302 through an electrical connection line 6, so that the electrical connection between the ballast 302 and the germicidal lamp 301 can be ensured, and the germicidal lamp 301 in the embodiment of the utility model can maintain energy saving and steady current normal operation.

[0056] In this way, when the germicidal lamp 301 fails, only the germicidal lamp 301 can be removed for replacement, but there is no need to remove and replace the ballast 302. The new germicidal lamp 301 is then connected to the ballast 302 in the electric control box 4 through the electrical connection line 6, so that the germicidal lamp assembly 3 can continue to work.

[0057] It is understandable that there is another situation in the air duct machine 100 of the embodiment of the utility model, that is, the germicidal lamp 301 functions intactly but the ballast 302 fails. At this time, the ballast 302 in the electrical control box 4 can be removed separately and replaced with a new ballast 302. The new ballast 302 is connected to the germicidal lamp 301 in the heat exchanger 2 through the electrical connecting line 6. Similarly, the germicidal lamp assembly 3 can continue to work normally.

[0058] Furthermore, the ballast 302 in the embodiment of the utility model is arranged inside the electric control box 4, so that the electric control box 4 can play a waterproof role for the ballast 302, thereby ensuring the safety and device life of the ballast 302 in the air duct machine 100.

[0059] Therefore, the utility model sets the sterilization lamp 301 in the heat exchanger 2, sets the ballast 302 in the electric control box 4, and the heat exchanger 2 and the ballast 302 are electrically connected through the electrical connection line 6, so that the sterilization lamp 301 and the ballast 302 in the sterilization lamp assembly 3 can be set separately. In this way, when the sterilization lamp 301 is damaged, only the sterilization lamp 301 can be replaced without replacing the ballast 302, thereby saving the maintenance cost of the duct machine 100.

[0060] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, a docking terminal 401 is provided in the electric control box 4 , the ballast 302 is electrically connected to the docking terminal 401 , and the germicidal lamp 301 is electrically connected to the docking terminal 401 .

[0061] Specifically, in the air duct machine 100 of the embodiment of the utility model, the germicidal lamp 301 and the ballast 302 are respectively provided with electrical connection wires 6, and the electrical connection wires 6 are extended to be connected to each other.

[0062] A docking terminal 401 is provided between the two sections of the electrical connection line 6 between the germicidal lamp 301 and the ballast 302. The docking terminal 401 includes at least two sub-docking terminals 4011. The two sub-docking terminals 4011 can be repeatedly assembled and disassembled.

[0063] The two sub-docking terminals 4011 are respectively connected to the two sections of electrical connection wires 6 on the germicidal lamp 301 and the ballast 302. By connecting the two sub-docking terminals 4011, the two sections of electrical connection wires 6 on the germicidal lamp 301 and the ballast 302 can be connected, thereby realizing the electrical connection between the germicidal lamp 301 and the ballast 302.

[0064] Furthermore, after the two sub-connecting terminals 4011 are separated, the two sections of electrical connection wires 6 on the germicidal lamp 301 and the ballast 302 are disconnected, so that the germicidal lamp 301 and the ballast 302 are electrically disconnected, but the functions of the germicidal lamp 301, the ballast 302 and the two sections of electrical connection wires 6 remain intact.

[0065] Furthermore, at least one of the germicidal lamp 301 or the ballast 302 is disassembled to repair and replace the faulty one of the germicidal lamp 301 and the ballast 302 separately, and at this time, the germicidal lamp 301 and the ballast 302 that is functioning well does not need to be disassembled and replaced.

[0066] When the faulty one of the germicidal lamp 301 and the ballast 302 is replaced with a new component, the new component is also provided with the electrical connection line 6 and the sub-butt terminal 4011 connected to the electrical connection line 6, and the new sub-butt terminal 4011 has the same parts as the butt terminal 401 in the duct machine 100. In this way, the replaced sub-butt terminal 4011 can be connected with the sub-butt terminal 4011 in the duct machine 100, so that the replaced new component can be installed in the duct machine 100, so that the germicidal lamp assembly 3 can continue to work normally.

[0067] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, a control board 402 is disposed in the electric control box 4 , and the ballast 302 and the germicidal lamp 301 are electrically connected to the control board 402 .

[0068] Specifically, the duct machine 100 in the embodiment of the utility model is electrically connected to the heat exchanger 2 and the fan assembly, and is also electrically connected to the germicidal lamp 301 and the ballast 302 in the germicidal lamp assembly 3. In this way, the germicidal lamp 301 and the ballast 302 in the duct machine 100 of the utility model can send and receive control signals with the control board 402.

[0069] The control board 402 is electrically connected to the germicidal lamp 301, and can control the working state of the germicidal lamp 301, so as to control the germicidal lamp 301 to sterilize and disinfect the air around the heat exchanger 2 when the air duct machine 100 is working. The control board 402 can also be electrically connected to the ballast 302, and can control the working state of the ballast 302 to ensure that the germicidal lamp 301 can work normally, and can ensure the energy saving and circuit safety of the germicidal lamp 301.

[0070] The sterilization lamp assembly 3, the heat exchanger 2, and the fan assembly in the duct machine 100 of the utility model can be uniformly controlled by the control board 402. In this way, when using the duct machine 100, the user only needs to send instructions to the control board 402 of the duct machine 100 to simultaneously control the functions of the heat exchanger 2 and the fan assembly and the function of the sterilization component, which is convenient to operate.

[0071] In some specific embodiments of the present invention, Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, the germicidal lamp 301 includes a germicidal lamp body 3011 , an adapter 3012 and a sealing assembly 5 .

[0072] The germicidal lamp body 3011 of the embodiment of the utility model includes but is not limited to a lamp tube and a bulb. The germicidal lamp body 3011 can emit light with a bactericidal effect to sterilize and disinfect the air, thereby achieving the effect of cleaning the air.

[0073] The adapter 3012 is arranged at one end of the germicidal lamp body 3011, and the end thereof away from the germicidal lamp body 3011 is electrically connected to the electrical connecting line 6. In this way, the germicidal lamp body 3011 can be conveniently connected to the electrical connecting line 6 so that the germicidal lamp body 3011 can receive and send electrical signals, thereby enabling the control of the germicidal lamp body 3011 by the control board 402.

[0074] An electrical connection pin 3013 is provided at one end of the germicidal lamp body 3011, and a socket corresponding to the electrical connection pin 3013 is provided on the adapter 3012. The electrical connection pin 3013 is inserted into the socket to achieve electrical connection between the germicidal lamp body 3011 and the adapter 3012, and then the germicidal lamp body 3011 can be electrically connected to the electrical connection line 6. In this way, the germicidal lamp body 3011 can be electrically connected to the ballast 302.

[0075] It should be noted that the number of electrical connection pins 3013 on the germicidal lamp 301 can be set according to the structural requirements of the duct unit 100 , and the number of jacks on the adapter 3012 is set corresponding to the number of electrical connection pins 3013 on the germicidal lamp 301 .

[0076] For example, one end of the germicidal lamp body 3011 is provided with four electrical connection pins 3013 , and the adapter 3012 is provided with four sockets, and the four sockets are provided in a one-to-one correspondence with the four electrical connection pins 3013 .

[0077] Furthermore, the sealing component 5 is sleeved at the connection between the adapter 3012 and the germicidal lamp body 3011, which can prevent water outside the germicidal lamp component 3 from entering the interior through the adapter 3012 and the germicidal lamp body 3011 and causing a short circuit, thereby affecting the electrical safety and service life of the germicidal lamp component 3.

[0078] Furthermore, the sealing assembly 5 is sleeved on the circumferential outer side of the connection between the adapter 3012 and the germicidal lamp body 3011, which can improve the sealing effect of the connection between the adapter 3012 and the germicidal lamp body 3011 to prevent water from entering the interior of the germicidal lamp assembly 3, thereby ensuring the reliability of the germicidal lamp body 3011 and the adapter.

[0079] In some specific embodiments of the present invention, Figure 3 As shown, the sealing assembly 5 includes a sealing seat 501 and a sealing gasket 503 .

[0080] Specifically, the sealing seat 501 is sleeved on the outer circumferential side of the connection between the adapter 3012 and the germicidal lamp body 3011, which can prevent the outer circumferential side of the adapter 3012 and the germicidal lamp body 3011 from contacting water. A sealing cavity 502 is defined between the sealing seat 501 and the germicidal lamp 301, which can provide a location for the sealing gasket 503.

[0081] The sealing gasket 503 is disposed in the sealing cavity 502 and has an interference fit with the germicidal lamp 301 , so that the connection between the adapter 3012 and the germicidal lamp 301 can be sealed.

[0082] In addition, combined Figure 7 As shown, mounting seats 30111 are provided at both ends of the length direction of the germicidal lamp body 3011, and the connection between the mounting seat 30111 and the germicidal lamp body 3011 is sealed with glue, which can prevent water from entering the germicidal lamp body 3011 and improve the sealing performance at both ends of the germicidal lamp body 3011 to ensure the electrical safety and service life of the germicidal lamp body 3011.

[0083] In the prior art, if the main body 3011 of the germicidal lamp is a lamp tube, in order to increase the irradiation range of the germicidal lamp 301, the length of the lamp tube is generally set to be longer, and the material is brittle and easy to break. Installing mounting seats 30111 at both ends of the main body 3011 of the germicidal lamp can enhance the structural strength of both ends of the main body 3011 of the germicidal lamp, which can not only protect the column of the germicidal lamp 301, but also the mounting seats 30111 can withstand greater stress, so that the installation of the main body 3011 of the germicidal lamp can be facilitated.

[0084] Furthermore, the electrical connection needle 3013 can be arranged on a side of the mounting seat 30111 away from the body of the germicidal lamp 301 , and the mounting seat 30111 can extend into the sealing seat 501 so that the electrical connection needle 3013 can be plugged into the adapter 3012 .

[0085] It can be understood that, in this way, the sealing seat 501 is sleeved on the circumferential outer side of the adapter 3012 and the mounting seat 30111, and defines a sealing cavity 502 between the sealing seat 501 and the mounting seat 30111. The sealing gasket 503 is arranged in the sealing cavity 502 and has an interference fit with the germicidal lamp 301.

[0086] In the embodiment of the utility model, the sealing pad 503 includes but is not limited to a rubber sealing pad, which has a certain elasticity and can be deformed under the condition of pressure or temperature change. That is to say, at room temperature and without external pressure, the radial cross-sectional dimension of the mounting seat 30111 is larger than the radial cross-sectional inner circle dimension of the rubber sealing pad.

[0087] In some embodiments of the present invention, the axial interference fit between the rubber sealing pad and the mounting seat 30111 is a, and a≤0.2mm.

[0088] At room temperature and without external pressure, the difference between the radial cross-sectional diameter of the mounting seat 30111 and the inner diameter of the radial cross-sectional diameter of the rubber gasket cannot be too large, otherwise it will affect the difficulty of assembling the rubber gasket and the mounting seat 30111. In order to ensure the convenience of assembling the rubber gasket and the mounting seat 30111, the axial interference a between the rubber gasket and the mounting seat 30111 is set not to exceed the first parameter value. For example, the first parameter value can be 0.2mm, 0.19mm, or 0.18mm. Consider selecting a suitable and specific parameter in the specific design.

[0089] In some embodiments of the present invention, the axial interference fit between the rubber sealing pad and the mounting seat 30111 is a, and a≥0.1 mm.

[0090] At room temperature and without external pressure, the difference between the radial cross-sectional diameter of the mounting seat 30111 and the inner diameter of the radial cross-sectional diameter of the rubber gasket cannot be too small. If it is too small, the sealing effect of the sealing gasket 503 on the connection between the adapter 3012 and the mounting seat 30111 will be reduced, which may easily cause water to enter the germicidal lamp assembly 3, thereby affecting the electrical safety and service life of the germicidal lamp assembly 3. In order to ensure the sealing effect of the sealing gasket 503 on the connection between the adapter 3012 and the mounting seat 30111, the axial interference a between the rubber gasket and the mounting seat 30111 is set to be not less than the second parameter value. For example, the second parameter value can be 0.11mm, 0.12mm, or 0.13mm. Consider selecting a suitable and specific parameter in the specific design.

[0091] In some embodiments of the present application, the axial interference fit between the rubber sealing gasket and the mounting seat 30111 is a, 0.1mm≤a≤0.2mm.

[0092] By setting the axial interference fit between the rubber sealing gasket and the mounting seat 30111 to any value between 0.1mm and 0.2mm, not only the installation convenience of the sealing gasket 503 and the germicidal lamp body 3011 can be improved, but also the sealing reliability of the connection between the sealing gasket 503 and the adapter 3012 and the mounting seat 30111 can be ensured.

[0093] In addition, the rubber sealing pad can play a certain role in reducing vibration, and can reduce the impact of the housing 1 of the duct machine 100 on the germicidal lamp assembly 3 when vibrating, so as to improve the working reliability of the germicidal lamp assembly 3.

[0094] In some specific embodiments of the present invention, Figure 7 As shown, the sealing seat 501 includes a seat body 5011 and a cover body 5012 .

[0095] The seat body 5011 is sleeved on the circumferential outer side of the connection between the adapter 3012 and the germicidal lamp body 3011 to shield the connection between the adapter 3012 and the germicidal lamp body 3011, thereby preventing water from directly entering the interior through the connection between the adapter 3012 and the germicidal lamp body 3011.

[0096] The cover body 5012 is threadedly connected to the base body 5011 at one end away from the germicidal lamp main body 3011, which not only simplifies the connection structure between the cover body 5012 and the cover body, and thus simplifies the connection operation between the cover body 5012 and the base body 5011, but also helps to improve the sealing effect between the cover body 5012 and the base body 5011, and can prevent water from entering the sealing seat 501 through the connection between the cover body 5012 and the base body 5011, thereby improving the electrical safety of the adapter 3012.

[0097] In addition, the cover body 5012 can cover the open side of the seat body 5011 and prevent water from entering the interior of the seat body 5011 to improve the waterproofness of the sealing seat 501.

[0098] A sealing head 30121 is provided at one end of the adapter 3012 away from the germicidal lamp body 3011. The sealing head 30121 is conical, and the cross-sectional area gradually decreases in the direction away from the germicidal lamp body 3011. The sealing head 30121 passes through the cover body 5012 and is sealed with the cover body 5012.

[0099] Specifically, the end of the adapter 3012 away from the germicidal lamp body 3011 can be matched with the inner wall of the cover 5012 in a conical surface. The axial position accuracy of the conical surface match is high, and after the adapter 3012 is matched with the cover 5012, the electrical connection line 6 on the adapter 3012 can correspond to the through hole on the cover 5012, so that the electrical connection line 6 can be smoothly extended from the cover 5012 and then electrically connected to the ballast 302.

[0100] In addition, the adapter 3012 and the cover body 5012 are matched through the conical surface, which can increase the sealing between the adapter 3012 and the cover body 5012, thereby effectively preventing water from entering the germicidal lamp assembly 3 through the matching surface of the adapter 3012 and the cover body 5012, thereby improving the waterproofness of the germicidal lamp assembly 3.

[0101] Therefore, the seat body 5011 of the sealing seat 501 is sealed with the adapter 3012 and the mounting seat 30111 by the sealing gasket 503, and the cover body of the sealing seat 501 is sealed with the adapter 3012 by the conical surface, so that the sealing effect between the sealing seat 501 and the adapter 3012 can be better, which can not only prevent water outside the sealing seat 501 from entering its interior, but also prevent moisture in the air from entering the sealing seat 501 and condensing into water when it encounters cold, which can effectively ensure the electrical safety and service life of the sterilization lamp assembly 3.

[0102] In some specific embodiments of the present invention, Figure 7 and Figure 8 As shown, a connecting plate 504 is disposed on the outer side of the sealing seat 501 . The connecting plate 504 is used to be connected to the heat exchanger 2 . An observation port 5041 is formed on the connecting plate 504 .

[0103] The connecting plate 504 is connected and fixed to the sealing seat 501, and is arranged on the outside of the sealing seat 501, so that the sealing seat 501 can provide a position for connection with other structural parts. The position of the sealing seat 501 in the duct machine 100 is fixed by the connecting plate 504, and the sterilization lamp assembly 3 can be fixed in the duct machine 100, thereby improving the installation convenience and position reliability of the sterilization lamp assembly 3.

[0104] The observation port 5041 is arranged on the connecting plate 504 , so that the connecting plate 504 can provide a stable and reliable setting position for the observation port 5041 , thereby ensuring the structural reliability of the observation port 5041 in the germicidal lamp assembly 3 .

[0105] Specifically, by connecting with the heat exchanger 2 through the connecting plate 504, the sealing seat 501 can be fixed in the heat exchanger 2, and then the sterilization lamp assembly 3 can be fixed in the heat exchanger 2. In this way, the structural reliability of the sterilization lamp assembly 3 in the heat exchanger 2 can be ensured, and the sterilization lamp assembly 3 can irradiate and sterilize the air around the heat exchanger 2, so that the duct machine 100 blows out clean air.

[0106] Since the light emitted by the germicidal lamp main body 3011 is harmful to the human body to a certain extent, and the human eye cannot directly see the light emitted by the germicidal lamp main body 3011, an observation port 5041 is opened on the connecting plate 504, through which the light around the germicidal lamp main body 3011 can be observed, which not only prevents the human eye from directly seeing the germicidal light, but also allows the working status of the germicidal lamp main body 3011 to be observed, and further, it can be determined whether the germicidal lamp main body 3011 is faulty, so that the user can replace the new germicidal lamp main body 3011 in time.

[0107] In some specific embodiments of the present invention, Fig. 9 As shown, at least part of the sealing seat 501 corresponding to the connecting plate 504 is provided with a baffle member 5013, which is arranged on the side of the connecting plate 504 facing the germicidal lamp body 3011, and the baffle member 5013 and the connecting plate 504 jointly define a photosensitive groove 505, and the observation port 5041 is located on one side of the photosensitive groove 505.

[0108] The baffle member 5013 is arranged on the side of the connecting plate 504 facing the germicidal lamp body 3011, and can be used to block the light emitted by the germicidal lamp body 3011. On the one hand, it can prevent the sterilizing light from leaking out of the heat exchanger 2, thereby avoiding the sterilizing light from causing harm to the user. On the other hand, it can enhance the intensity of the sterilizing light in the heat exchanger 2, which is beneficial to improving the sterilization effect of the germicidal lamp assembly 3.

[0109] The photosensitive groove 505 is defined by the baffle 5013 and the connecting plate 504, and corresponds to one side of the observation port 5041. In this way, a small portion of the light emitted by the germicidal lamp body 3011 can enter the photosensitive groove 505, so that the surrounding light of the germicidal lamp body 3011 can be observed through the observation port 5041 to determine the working status of the germicidal lamp body 3011.

[0110] Furthermore, a transparent stopper 8 is provided at the observation port 5041 , which not only allows light to pass through the observation port 5041 , but also prevents water from entering the observation port 5041 , thereby ensuring the waterproofness of the sealing seat 501 .

[0111] According to some specific embodiments of the present invention, combined with Figure 3 and Figure 4 As shown, the heat exchanger 2 includes two straight heat exchangers 201 arranged back to back and tilted, one end of the two straight heat exchangers 201 are connected to each other to form a connecting end 2011, the other end of the two straight heat exchangers 201 is a free end 2012, and the sterilization lamp 301 is arranged between the two straight heat exchangers 201.

[0112] Specifically, in order to improve the heat exchange efficiency of the heat exchanger 2 and enhance the structural compactness of the product in the vertical duct machine, one end of the two heat exchangers 2 is set in abutment and the other end is set open, and sealing plates 7 are set on the sides of the two heat exchangers 2 to prevent the outflow of the heat exchange airflow.

[0113] When the germicidal lamp 301 is connected to the heat exchanger 2 through the connecting plate 504 to be set in the heat exchanger 2, the connecting plate 504 can be connected to the sealing plate 7, so that the germicidal lamp 301 can be set between the two straight heat exchangers 201, and no additional fixing plate is required. In this way, the germicidal lamp body 3011 can sterilize and disinfect the air around the two straight heat exchangers 201, which can not only improve the sterilization efficiency, but also improve the quality of the air sent to the room by the air duct machine 100.

[0114] According to some other specific embodiments of the present invention, Figure 5 As shown, the heat exchanger 2 includes two straight heat exchangers 201 arranged back to back and tilted, one end of the two straight heat exchangers 201 are connected to each other to form a connecting end 2011, and the other end of the two straight heat exchangers 201 is a free end 2012, and the sterilization lamp 301 is arranged on the side of one of the two straight heat exchangers 201 away from the other.

[0115] Specifically, in order to improve the heat exchange efficiency of the heat exchanger 2 and enhance the structural compactness of the product in the vertical duct machine, one end of the two heat exchangers 2 is set in abutment and the other end is set open, and sealing plates 7 are set on the sides of the two heat exchangers 2 to prevent the heat exchange air flow from flowing out.

[0116] The germicidal lamp 301 can be directly connected to the side of one of the two straight heat exchangers 201 away from the other through the connecting plate 504, and no additional fixing plate is required. In this way, the germicidal lamp 301 can be arranged close to the heat exchanger 2 to ensure that the germicidal light emitted by the germicidal lamp body 3011 can irradiate the air around the heat exchanger 2 to sterilize and disinfect the air.

[0117] like Figure 1-Figure 10 As shown, the duct machine 100 according to the embodiment of the utility model includes a housing 1, a heat exchanger 2, a fan assembly and a germicidal lamp assembly 3.

[0118] The casing 1 is used to be placed vertically on the ground, and the casing 1 is provided with an air inlet and an air outlet, the heat exchanger 2 is arranged in the casing 1, the fan assembly is arranged in the casing 1 and is located on one side of the heat exchanger 2, the fan assembly drives the air to enter the casing 1 from the air inlet, and the air exchanges heat with the heat exchanger 2 to form a heat exchange airflow, and then is driven by the fan assembly to enter the room from the air outlet.

[0119] The casing 1 may have multiple air inlets, for example, one air inlet may be an air inlet for outdoor fresh air, and another air inlet may be an air inlet for indoor air. In addition, the fan assembly may be located on one side of the heat exchanger 2 adjacent to the air outlet.

[0120] In this way, the duct machine 100 can selectively control outdoor fresh air and indoor air to enter the casing 1 through the air inlets through multiple air inlets, and the outdoor fresh air or indoor air can form a heat exchange airflow after heat exchange with the heat exchanger 2, and then be driven by the fan assembly to be introduced into the room from the air outlet, thereby realizing indoor cooling or heating.

[0121] The germicidal lamp assembly 3 is arranged in the housing 1, so that the germicidal lamp assembly 3 is installed during the production process, and an installation position and an interface can be reserved for the germicidal lamp assembly 3 in the housing 1 to facilitate the installation of the germicidal lamp assembly 3. Compared with the prior art, in which the installation of the germicidal lamp and the ballast requires opening a hole in the air duct of the air duct machine on site, the installation operation of the germicidal lamp 301 in the embodiment of the utility model is more time-saving and labor-saving.

[0122] In the embodiment of the utility model, the germicidal lamp assembly 3 includes a germicidal lamp 301 and a ballast 302. The germicidal lamp 301 is arranged in the heat exchanger 2, so that the light emitted by the germicidal lamp 301 can directly irradiate the air around the heat exchanger 2, so that the germicidal lamp 301 can sterilize and disinfect the air around the heat exchanger 2.

[0123] In this way, when the air after heat exchange is driven by the fan assembly to enter the room from the air outlet, it can ensure that the cleanliness of the air entering the room meets the user's requirements, making this product more in line with the user's usage needs, thereby improving the user's usage experience

[0124] The ballast 302 is electrically connected to the germicidal lamp 301, so that the high voltage generated by the ballast 302 can ensure that the germicidal lamp 301 is normally turned on, and can stabilize the current of the germicidal lamp 301, which is beneficial to energy saving of the germicidal lamp 301 and protection of the circuit safety of the germicidal lamp 301.

[0125] In the related art, the germicidal lamp and the duct unit are integrated, and the ballast is installed and removed together when the germicidal lamp is installed and removed. However, compared with the ballast, the service life of the germicidal lamp is shorter and the failure frequency is higher. Therefore, in the prior art, when replacing the germicidal lamp, the ballast needs to be replaced together, and most of the ballasts at this time are in good working order. Such operation will cause unnecessary waste of the ballast, thereby increasing the replacement cost and use cost of the duct unit.

[0126] The germicidal lamp 301 and the ballast 302 in the embodiment of the utility model are connected via an electrical connection line 6, so that not only the electrical connection between the ballast 302 and the germicidal lamp 301 can be ensured, but also when the germicidal lamp 301 fails, only the germicidal lamp 301 can be removed and replaced without removing and replacing the ballast 302.

[0127] It is understandable that there is another situation in the air duct machine 100 of the embodiment of the utility model, that is, the germicidal lamp 301 functions intactly but the ballast 302 fails. At this time, the ballast 302 can be removed separately and replaced with a new ballast 302. The new ballast 302 is connected to the germicidal lamp 301 in the heat exchanger 2 through the electrical connection line 6. Similarly, the germicidal lamp assembly 3 can continue to work normally.

[0128] Therefore, the utility model sets the germicidal lamp 301 and the ballast 302 in the germicidal lamp assembly 3 separately. In this way, when the germicidal lamp 301 is damaged, only the germicidal lamp 301 can be replaced without replacing the ballast 302, thereby saving the maintenance cost of the air duct machine 100.

[0129] Other structures and operations of the duct machine 100 according to the embodiment of the utility model are known to ordinary technicians in this field and will not be described in detail here.

[0130] The duct air conditioner 100 of the present invention performs a refrigeration cycle of the duct air conditioner 100 by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0131] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0132] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air duct unit 100 can adjust the temperature and humidity of the indoor space.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0134] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
