Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a dehumidifier. Background Art

[0002] At present, with the improvement of living standards, people have higher and higher functional requirements for air conditioners. Therefore, dehumidifiers for reducing indoor humidity have come into being. The dehumidification process of a dehumidifier is generally to use a fan to suck indoor air into the air duct, so that the indoor air passes through the evaporator and condenser in the air duct in turn, and the moisture is precipitated under the heat exchange of the evaporator and condenser, thereby achieving a dehumidification effect. However, in current dehumidifiers, there is a certain gap between the evaporator and condenser and the air duct. When part of the air flows in the air duct, it directly passes through the gap instead of the evaporator and condenser, causing air leakage, reducing the heat exchange and dehumidification efficiency, affecting the heat exchange and dehumidification effect, and poor user experience. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Please refer to Figures 1 to 3 The embodiment of the present invention provides a dehumidifier 100 for reducing indoor air humidity. It can ensure that all air passes through the evaporator 130 and the condenser 140, avoid air leakage, improve heat exchange and dehumidification efficiency, ensure heat exchange and dehumidification effect, and improve user experience.

[0024] It should be noted that the dehumidifier 100 is placed indoors. The dehumidifier 100 can absorb the indoor air and dehumidify it, and then discharge the dehumidified air into the room, so as to achieve the dehumidification effect on the indoor air.

[0025] The dehumidifier 100 includes a volute 110, a centrifugal fan 120, an evaporator 130, a condenser 140 and a support frame 150. The volute 110 has an air inlet 111, and the air inlet 111 is used for air to flow into the volute 110. The evaporator 130 and the condenser 140 are both arranged outside the air inlet 111. The evaporator 130 is located on the side of the condenser 140 away from the air inlet 111, so that the air passes through the evaporator 130 and the condenser 140 in sequence before flowing into the air inlet 111. The centrifugal fan 120 is installed on the volute 110, and the centrifugal fan 120 is used to generate negative pressure to drive the air to pass through the evaporator 130 and the condenser 140 in sequence and enter the air inlet 111. Specifically, a limit plate 116 is extended from the top of the volute 110, and the evaporator 130 and the condenser 140 are both interference fit with the limit plate 116 to prevent a gap from being generated between the evaporator 130 and the limit plate 116, and to prevent a gap from being generated between the condenser 140 and the limit plate 116. In this way, all air can be ensured to pass through the evaporator 130 and the condenser 140, avoiding air leakage, improving the heat exchange and dehumidification efficiency, ensuring the heat exchange and dehumidification effect, and improving the user experience.

[0026] Furthermore, the volute 110 is mounted on a support frame 150, and the support frame 150 is used to limit and fix the volute 110 to prevent the volute 110 from being displaced relative to the support frame 150. The support frame 150 is extended with an extension plate 151, and the extension plate 151 is spaced apart from the limiting plate 116. The evaporator 130 and the condenser 140 are both mounted on the extension plate 151 and are both disposed between the extension plate 151 and the limiting plate 116. The extension plate 151 is used to support and fix the evaporator 130 and the condenser 140 to prevent the evaporator 130 and the condenser 140 from being displaced relative to the extension plate 151. The indoor air can enter between the extension plate 151 and the limiting plate 116 under the action of the centrifugal fan 120, and pass through the evaporator 130 and the condenser 140 in sequence, and then flow back into the room through the volute 110.

[0027] It is worth noting that the dehumidifier 100 also includes a housing 160, a compressor 170 and a throttling device (not shown). The volute 110, the centrifugal fan 120, the evaporator 130, the condenser 140, the support frame 150, the compressor 170 and the throttling device are all arranged in the housing 160, the evaporator 130 and the condenser 140 are arranged at intervals, and the condenser 140 is arranged between the evaporator 130 and the volute 110. The centrifugal fan 120 is used to drive the air to pass through the evaporator 130 and the condenser 140 in sequence, and flow into the room through the volute 110. In this process, the evaporator 130 and the condenser 140 work together to dehumidify the air passing through, so as to achieve the effect of dehumidification without affecting the indoor temperature.

[0028] Furthermore, the compressor 170, the condenser 140, the throttling device and the evaporator 130 are connected end to end and combined to form a refrigerant flow path for the refrigerant to flow. During the refrigerant flow, the compressor 170 is used to compress the refrigerant and transport the high-temperature and high-pressure gaseous refrigerant to the condenser 140; the condenser 140 is used to perform heat exchange on the refrigerant to cool the high-temperature and high-pressure gaseous refrigerant to a low-temperature and high-pressure liquid refrigerant and make it flow to the throttling device; the throttling device is used to throttle the refrigerant to change the low-temperature and high-pressure liquid refrigerant to a low-temperature and low-pressure liquid refrigerant and make it flow to the evaporator 130; the evaporator 130 is used to perform heat exchange on the refrigerant to change the low-temperature and low-pressure liquid refrigerant to a low-pressure gaseous refrigerant and make it flow back to the compressor 170. During this process, the centrifugal fan 120 generates negative pressure to draw indoor air into the housing 160, and passes through the evaporator 130 and the condenser 140 in sequence to form an outlet airflow, and is finally blown outward through the volute 110 to achieve a dehumidification function.

[0029] Specifically, in the process of the outlet airflow passing through the evaporator 130, the low-temperature and low-pressure liquid refrigerant in the evaporator 130 absorbs the heat of the outlet airflow, so that the moisture in the outlet airflow condenses on the evaporator 130 and forms condensation. At this time, the outlet airflow cools down, and the low-temperature and low-pressure liquid refrigerant heats up to form a low-pressure gaseous refrigerant, thereby realizing the dehumidification function. In the process of the outlet airflow passing through the condenser 140, the outlet airflow absorbs the heat of the high-temperature and high-pressure gaseous refrigerant in the condenser 140. At this time, the outlet airflow heats up (restores to a temperature close to the indoor temperature), and the high-temperature and high-pressure gaseous refrigerant cools down to form a low-temperature and high-pressure liquid refrigerant. In this way, since the outlet airflow first cools down and then heats up in the process of passing through the evaporator 130 and the condenser 140 at one time, and finally reaches a level close to the indoor temperature, the outlet airflow blown out from the volute 110 will not have much impact on the indoor temperature, thereby improving the user experience.

[0030] In this embodiment, the limit plate 116 has a demoulding slope to facilitate demoulding of the limit plate 116, thereby facilitating the production of the volute 110. Specifically, the limit plate 116 is arranged obliquely to the plane where the air inlet 111 is located, and the limit plate 116 gradually rises in its extension direction, that is, the limit plate 116 gradually moves away from the extension plate 151 in the direction away from the air inlet 111. The demoulding slope ranges from 0.5 degrees to 3 degrees. A reasonable demoulding slope can facilitate demoulding of the limit plate 116 while ensuring the strength of the limit plate 116.

[0031] In this embodiment, the demoulding angle is 1 degree, but it is not limited thereto. In other embodiments, the demoulding angle may be 0.5 degree or 3 degrees. There is no specific limitation on the magnitude of the demoulding angle.

[0032] Please refer to Figure 4 It is worth noting that both the evaporator 130 and the condenser 140 are plate heat exchangers, and both the evaporator 130 and the condenser 140 are in the shape of rectangular plates. The evaporator 130 and the condenser 140 are arranged in parallel and spaced apart, and are both parallel to the plane where the air inlet 111 is located, so as to improve the uniformity of heat exchange for the air and ensure the air intake effect. The evaporator 130 has a first top surface 131, and the condenser 140 has a second top surface 141. The first top surface 131 is parallel to the second top surface 141, and the first top surface 131 is arranged higher than the second top surface 141. The first top surface 131 and the second top surface 141 are both matched with the limiting plate 116 to avoid air leakage, improve the heat exchange and dehumidification efficiency, and ensure the heat exchange and dehumidification effect. Specifically, since the limit plate 116 gradually rises in the direction away from the air inlet 111, and the evaporator 130 is located on the side of the condenser 140 away from the air inlet 111, in order to ensure that the evaporator 130 and the condenser 140 are both interference fit with the limit plate 116, the evaporator 130 is raised so that the height of the first top surface 131 of the evaporator 130 is higher than the height of the second top surface 141 of the condenser 140, thereby ensuring the reliability of the fit between the first top surface 131 and the second top surface 141 and the limit plate 116.

[0033] In this embodiment, the end of the first top surface 131 close to the air inlet 111 is in interference fit with the limiting plate 116, and the end of the first top surface 131 away from the air inlet 111 forms a first gap 132 with the limiting plate 116, and the first gap 132 is set in a triangular shape, that is, the first top surface 131 part is in interference fit with the limiting plate 116, so that it is convenient to assemble the evaporator 130 while ensuring the anti-leakage effect, achieving the effect of labor saving, thereby improving the assembly efficiency. Similarly, the end of the second top surface 141 close to the air inlet 111 is in interference fit with the limiting plate 116, and the end of the second top surface 141 away from the air inlet 111 forms a second gap 142 with the limiting plate 116, and the second gap 142 is set in a triangular shape, that is, the second top surface 141 part is in interference fit with the limiting plate 116, so that it is convenient to assemble the condenser 140 while ensuring the anti-leakage effect, achieving the effect of labor saving, thereby improving the assembly efficiency.

[0034] Please continue to refer to Figure 2 The volute 110 includes a first shell 112 and a second shell 113. The first shell 112 and the second shell 113 are detachably connected to facilitate assembly and disassembly of the first shell 112 and the second shell 113, thereby facilitating maintenance and cleaning of the volute 110. The first shell 112 and the second shell 113 together form an installation cavity 114, and the centrifugal fan 120 is installed in the installation cavity 114. The air inlet 111 is opened on the first shell 112, and the second shell 113 is opened with an air outlet 115. The air inlet 111 is connected to the air outlet 115 through the installation cavity 114. The centrifugal fan 120 can drive air from the air inlet 111 into the installation cavity 114, and then blow it out to the room through the air outlet 115.

[0035] The first shell 112 of the volute 110 includes an end wall 1121, a top wall 1122, a bottom wall 1123, a first side wall 1124, and a second side wall 1125. The air inlet 111 is opened on the end wall 1121, and the top wall 1122, the first side wall 1124, the bottom wall 1123, and the second side wall 1125 are connected end to end and are all connected to the end wall 1121, and are all arranged outside the air inlet 111. The top wall 1122, the first side wall 1124, the bottom wall 1123, and the second side wall 1125 are all arranged on the side of the end wall 1121 away from the installation cavity 114. The top wall 1122, the first side wall 1124, the bottom wall 1123, and the second side wall 1125 together enclose a closed cavity 1126. The outlet airflow passes through the closed cavity 1126 and enters the air inlet 111 under the action of the centrifugal fan 120. The top wall 1122 is connected to the limiting plate 116, and the limiting plate 116 is arranged at one end of the top wall 1122 away from the end wall 1121. An angle is formed between the limiting plate 116 and the top wall 1122, and the size of the angle is the same as the size of the demoulding slope of the limiting plate 116. Specifically, the first side wall 1124, the bottom wall 1123 and the second side wall 1125 are all against the condenser 140 to seal the gap between the first side wall 1124, the bottom wall 1123 and the second side wall 1125 and the condenser 140, and the limiting plate 116 is interference fit with the top of the condenser 140 to prevent air leakage, so as to ensure that the outlet airflow passing through the condenser 140 can all flow into the air inlet 111 through the closed cavity 1126, and then blow out through the volute 110, so as to ensure the air volume and air outlet effect.

[0036] In this embodiment, the limiting plate 116 , the end wall 1121 , the top wall 1122 , the bottom wall 1123 , the first side wall 1124 and the second side wall 1125 are integrally formed to improve the connection strength.

[0037] Please refer to Figure 5 It should be noted that the extension plate 151 is provided with a first clamping block 152, a second clamping block 153, a first support block 154 and a second support block 155. The first clamping block 152 is provided with a first clamping slot 156, and the evaporator 130 is clamped in the first clamping slot 156. The first clamping block 152 can limit the evaporator 130 through the first clamping slot 156 to fix the relative position of the evaporator 130 and the extension plate 151, and prevent the evaporator 130 from being displaced relative to the extension plate 151. Similarly, the second clamping block 153 is provided with a second clamping slot 157, and the condenser 140 is clamped in the second clamping slot 157. The second clamping block 153 can limit the condenser 140 through the second clamping slot 157 to fix the relative position of the condenser 140 and the extension plate 151, and prevent the condenser 140 from being displaced relative to the extension plate 151.

[0038] Furthermore, the top of the first support block 154 is at the same height as the bottom wall of the first slot 156, and the first support block 154 abuts against the evaporator 130. The first support block 154 is used to support the evaporator 130 to ensure the reliability of the evaporator 130 and the first slot 156. Similarly, the top of the second support block 155 is at the same height as the bottom wall of the second slot 157, and the second support block 155 abuts against the condenser 140. The second support block 155 is used to support the condenser 140 to ensure the reliability of the condenser 140 and the second slot 157.

[0039] In this embodiment, the number of the first clamping blocks 152 and the number of the second clamping blocks 153 are both two, the first support block 154 is disposed between the two first clamping blocks 152, and the second support block 155 is disposed between the two second clamping blocks 153. The two first clamping blocks 152 are disposed at opposite ends of the evaporator 130, and the two first clamping blocks 152 work together to improve the clamping and limiting effect on the evaporator 130 to prevent the evaporator 130 from being displaced; the two second clamping blocks 153 are disposed at opposite ends of the condenser 140, and the two second clamping blocks 153 work together to improve the clamping and limiting effect on the condenser 140 to prevent the condenser 140 from being displaced.

[0040] In this embodiment, the height of the evaporator 130 is smaller than the height of the condenser 140. In order to ensure that the evaporator 130 and the condenser 140 are both interference fit with the limit plate 116, the evaporator 130 is raised, that is, the bottom wall of the first slot 156 is set higher than the bottom wall of the second slot 157 to ensure the reliability of the cooperation between the evaporator 130 and the condenser 140 and the limit plate 116 to prevent air leakage.
