Description

TECHNICAL FIELD

[0001] The present application relates to the field of dehumidification equipment, in particular to a dehumidifier. BACKGROUND

[0002] The condensing dehumidifier sucks the humid air in the room into the machine through the internal fan, and when the sucked air passes through the condenser, the water vapor in the air will condense into liquid water due to the low temperature of the condenser surface. The condensed liquid water is collected in the water tank of the dehumidifier, and the dry air after treatment is discharged outside the machine by the fan after being heated (or naturally warmed up) by the condenser to near room temperature. The above process is repeated to gradually reduce the humidity in the room.

[0003] The existing dehumidifier has a small contact area between the condenser and the sucked air, which directly determines the heat exchange efficiency between the condenser and the air. A small area means that the heat exchange is not sufficient, resulting in unsatisfactory condensation effect. In order to achieve ideal dehumidification effect, the dehumidifier may need to run the condenser for a longer time or with higher energy consumption, which not only increases power consumption, but also may affect the service life of the dehumidifier and thus affect the dehumidification efficiency. At the same time, the small condensation surface area limits the amount of water that can be removed by the dehumidifier in a unit of time, thereby affecting the dehumidification effect. This problem is particularly evident in a humid environment.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0034] The existing dehumidifier has a small contact area between the condenser and the suction air, and the contact area directly determines the heat exchange efficiency between the condenser and the air. A small area means that the heat exchange is not sufficient, resulting in an unsatisfactory condensation effect. In order to achieve an ideal dehumidification effect, the dehumidifier may need to run the condenser for a longer time or with higher energy consumption, which not only increases the power consumption, but also may affect the service life of the dehumidifier and thus affect the dehumidification efficiency. At the same time, a small condensation surface area will limit the amount of moisture that can be removed by the dehumidifier in a unit of time, thereby affecting the dehumidification effect. This problem is particularly evident in a high-humidity environment.

[0035] To solve the above technical problems, the present embodiment provides a dehumidifier. Referring to Figures 1 to 6 , Figure 1 is a schematic view of the dehumidifier in the embodiments of the present application, Figure 2 is an exploded view of the dehumidifier in the embodiments of the present application, Figure 3 is a perspective view of the condensing assembly in the embodiments of the present application, Figure 4 is an exploded view of the condensing assembly in the embodiments of the present application, Figure 5 is a sectional view of the condensing assembly in the embodiments of the present application, Figure 6 is a perspective view of the condensing pipe in the embodiments of the present application.

[0036] The dehumidifier of the present embodiment includes a condensing assembly 1 for condensing air, as shown in Figure 3 and Figure 4 , the condensing assembly 1 includes a fixing seat 11, a condensing pipe 12, a sealing ring 13, an upper cover 14 and a lower cover 15.

[0037] As shown in Figure 4 , the fixing seat 11 is provided with a clamping plate 111, the clamping plate 111 is provided with a plurality of clamping pieces 112 at intervals along the length direction, a clamping groove 113 is formed between adjacent two clamping pieces 112, and the clamping groove 113 is used for clamping the condensing pipe 12.

[0038] As shown in FIG. Figure 5 , the number of condensing pipes 12 is the same as the number of clamping grooves 113 of the clamping plate 111, and each condensing pipe 12 is fixed in each clamping groove 113, as shown inFigure 6 As shown, the condensing pipe 12 is in contact with the two adjacent clamping pieces 112, and the inside of the condensing pipe 12 is provided with at least one partition 121, which separates the inside of the condensing pipe 12 into at least two condensing channels 122, and the partition 121 is used to increase the contact area between the condensing pipe 12 and the air.

[0039] As shown in Figure 4 and Figure 5 The upper cover 14 and the lower cover 15 are connected with the fixed seat 11 and are provided with a sealing ring 13 between the fixed seat 11, and the upper cover 14 and the lower cover 15 are respectively covered above and below the condensing pipe 12.

[0040] Among them, as shown in Figure 5 The fixed seat 11, the upper cover 14 and the lower cover 15 form an air flow channel 100, the fixed seat 11 is provided with an air inlet 101 and an air outlet 102 which respectively communicate with the front and rear ends of the air flow channel 100, and a water outlet hole 103 located below the condensing pipe 12, and the air flow channel 100 communicates with each condensing channel 122.

[0041] The condensing pipe 12 can be cooled by a refrigeration device to achieve the required temperature for air condensation.

[0042] The condensing assembly 1 of the above technical scheme is installed, and the fixed seat 11 is installed on the corresponding position of the dehumidifier, such as the inner wall of the shell 6, by using screws or other fixing parts. Then, the condensing pipe 12 is placed in the clamping groove 113 of the fixed seat 11 according to the designed number and position, and the condensing pipe 12 is fixed in the clamping groove 113 by using the clamping piece 112 or other fixing parts, to ensure that the condensing pipe 12 is in good contact with the adjacent clamping piece 112, so as to form a good heat exchange effect. Then, the sealing ring 13 is installed between the condensing pipe 12 and the fixed seat 11 to ensure the sealing between the condensing pipe 12 and the fixed seat 11. Finally, the upper cover 14 and the lower cover 15 are placed: the upper cover 14 and the lower cover 15 are respectively placed above and below the condensing pipe 12, and the upper cover 14 and the lower cover 15 are firmly fixed on the fixed seat 11 by using screws or other fixing parts, to ensure that they are tightly connected without looseness or gap.

[0043] The working process of the above technical solution is as follows: after the dehumidifier is started, the external humid air is sucked into the air flow channel 100 through the air inlet 101 provided on the fixed seat 11; the humid air flows in the air flow channel 100 and passes through the condensing pipe 12; the inside of the condensing pipe 12 is provided with at least one partition 121, which separates the inside of the condensing pipe 12 into at least two condensing channels 122, and the air flows in the condensing channel 122 and contacts the wall surface of the condensing pipe 12, causing the water vapor in the air to condense into liquid water; the condensed liquid water flows along the inner wall of the condensing pipe 12 to the bottom and is finally discharged through the water outlet hole 103 provided on the fixed seat 11 and flows into the water tank 9 below. The dry air after condensation continues to pass through the air flow channel 100 and is finally discharged through the air outlet 102 provided on the fixed seat 11.

[0044] The dehumidifier of the above technical solution increases the contact area of air with the wall surface of the condensing pipe 12 by separating the condensing pipe 12 into multiple condensing channels 122, thereby improving the condensation efficiency and enabling the dehumidifier to remove more moisture in a shorter time. At the same time, the design of the condensing assembly 1 enables the condensing pipe 12 to be stably fixed in the clamping groove 113 of the fixed seat 11, and the air flow channel 100 formed between the upper cover 14 and the lower cover 15 and the fixed seat 11 also ensures smooth air flow. This compact structure makes the dehumidifier more compact and portable, making it easy to carry and install. The condensing pipe 12 of the condensing assembly 1 cooperates with the clamping groove 113 of the clamping plate 111, and the connection is stable, but it can also be easily disassembled for cleaning and maintenance. It is also important that through the efficient condensation and dehumidification process, the dehumidifier can reduce energy consumption while reducing indoor humidity.

[0045] In order to further optimize the installation of the condensing pipe 12 by the fixed seat 11, refer to Figure 3 and Figure 5As shown, the fixing seat 11 is provided with three clamping plates 111, which are arranged at intervals along the height direction. The fixing seat 11 is provided with a ventilation opening 104 between any two adjacent clamping plates 111. Specifically, the fixing seat 11 is provided with three clamping plates 111, which are arranged at intervals or unequal intervals along the height direction (i.e. the vertical direction) of the dehumidifier. In actual manufacturing process, the number, shape and size of the clamping plates 111 can be adjusted according to the specific dehumidifier model, the size of the condensing pipe 12 and the condensing efficiency requirement. For example, in the case of higher condensing efficiency requirement, the number of clamping plates 111 can be increased to arrange the condensing pipe 12 more closely. At the same time, the material of the clamping plate 111 should have sufficient strength and corrosion resistance to ensure that it will not deform or damage during long-term use. Through the interval arrangement of the three clamping plates 111, the fixing seat 11 can more stably support the condensing pipe 12, reducing its shaking and deformation during work. The ventilation opening 104 between the clamping plates 111 enables the condensing pipe 12 to be in more sufficient contact with the air, thereby increasing the condensing area and improving the condensing efficiency. When the condensing pipe 12 needs to be cleaned or replaced, it can be conveniently operated through the opening between the clamping plates 111, reducing the maintenance difficulty and cost.

[0046] In order to reduce the risk of condensing channel 122 blockage, refer to Figure 6 As shown, the lower end surface of the condensing pipe 12 is a slope 123, and the opening of the lower end of the condensing pipe 12 is larger than the horizontal cross-sectional opening of the condensing channel 122. The slope 123 helps the condensate water flow out of the condensing pipe 12 more smoothly, avoiding the accumulation of water. At the same time, the opening of the lower end of the condensing pipe 12 is designed to be larger than the horizontal cross-sectional opening of the condensing channel 122. The purpose of this is to increase the flux of condensate water and dirt discharge, ensuring that the condensate water and dirt can be quickly discharged from the condensing pipe 12. In actual manufacturing process, the angle of the slope 123 and the size of the opening need to be accurately calculated and adjusted according to the size of the condensing pipe 12, the condensing efficiency and the discharge requirement of the condensate water, to ensure that the condensing pipe 12 can work normally and achieve the expected condensing effect. By avoiding the accumulation of water and dirt blockage, the corrosion and wear of the inside of the condensing pipe 12 can be reduced, thereby prolonging its service life.

[0047] In order to make the airflow gradually accelerate when passing through the airflow channel 100, thereby improving the condensing effect. Refer to Figure 5As shown, in some embodiments, the front end of the airflow channel 100 extends along the arrangement direction of the condensing pipe 12, and the caliber gradually decreases; in order to further optimize the flow state of the airflow above the condensing pipe 12, the fixed seat 11 is provided with a flow guide fin 114 above the condensing pipe 12, which is inclined downward along the extension direction of the front end of the airflow channel 100. In the actual manufacturing process, the material of the flow guide fin 114 should have sufficient strength and corrosion resistance to ensure that it will not deform or be damaged during long-term use. At the same time, the inclination angle and position of the flow guide fin 114 also need to be adjusted according to the arrangement mode of the condensing pipe 12, the shape of the airflow channel 100, and the condensing efficiency requirements. Through the design of the front end of the airflow channel 100 with gradually decreasing caliber and the setting of the flow guide fin 114, the flow state of the airflow above the condensing pipe 12 can be optimized to be more uniform and stable. The optimized airflow state helps to improve the condensing efficiency, so that the dehumidifier can achieve the expected dehumidification effect faster. At the same time, by optimizing the airflow state, the noise and vibration of the dehumidifier during operation can be reduced, and the comfort of use can be improved.

[0048] Further, referring to Figure 5 As shown, the flow guide fin 114 is arc-shaped, with the concave surface facing the condensing channel 122, and the convex surface of the flow guide fin 114 is provided with a convex part. The arc-shaped flow guide fin 114 and the convex part can further optimize the flow state of the airflow above the condensing pipe 12, making it more conform to the surface of the condensing pipe 12, thereby improving the condensing efficiency. The setting of the convex part increases the stability and strength of the flow guide fin 114, making it more stable during use and less prone to deformation or damage.

[0049] For example, the convex part is integrally formed on the convex surface of the flow guide fin 114.

[0050] In some embodiments, referring to Figure 1 and Figure 2 As shown, the dehumidifier further comprises a blower 2 and a dehumidifying wheel 3, the blower 2 is configured to suck air outside the dehumidifier into the condensing assembly 1, and can also deliver the air passing through the condensing pipe 12 to the dehumidifying wheel 3, the dehumidifying wheel 3 is made of ceramic material and is provided with honeycomb holes for delivering air, for example, the honeycomb holes are uniformly distributed on the dehumidifying wheel 3 and extend along the axial direction of the dehumidifying wheel 3 and penetrate through. During the condensing process, the air is subjected to the condensing action of the condensing pipe 12, thereby reducing its temperature and humidity; then, these treated air is delivered to the dehumidifying wheel 3 by the blower 2. The dehumidifying wheel 3 is made of ceramic material, which has good heat resistance and corrosion resistance. At the same time, the dehumidifying wheel 3 is also provided with honeycomb holes for delivering air. These honeycomb holes can make the air form a complex flow path inside the dehumidifying wheel 3, thereby increasing its contact area and time with the surface of the dehumidifying wheel 3, further improving the dehumidification effect.

[0051] In some embodiments, referring to Figure 1 and Figure 2 As shown, the dehumidification wheel 3 is rotatably arranged inside the dehumidifier, and the dehumidifier further comprises a rotating mechanism 4 configured to drive the dehumidification wheel 3 to rotate. By continuously rotating the dehumidification wheel 3 through the rotating mechanism 4, the contact area and time of the dehumidification wheel 3 with air can be increased, thereby improving the dehumidification efficiency. The rotation of the dehumidification wheel 3 can also make the air form a complex flow path inside the dehumidifier, thereby increasing the contact area and time of the air with the inside of the dehumidifier, which helps to further remove impurities and odors in the air and improve air quality.

[0052] For example, referring to Figure 1 and Figure 2 As shown, the dehumidification wheel 3 is mounted on a bracket 5 through a rotating shaft, the bracket 5 is fixed relative to a shell 6 of the dehumidifier, and the rotating mechanism 4 is a motor fixed on the bracket 5, which is in driving connection with the dehumidification wheel 3 through a transmission mechanism such as a gear set, thereby driving the dehumidification wheel 3 to rotate.

[0053] It can be understood that, referring to Figure 1 and Figure 2 As shown, the dehumidifier can further comprise a filter assembly 7 located at the front end of the condensation assembly 1, which can use an existing air filter device. After the air passes through the filter assembly 7, the air quality is improved.

[0054] In some embodiments, referring to Figure 1 and Figure 2 As shown, the condensation pipe 12 can need to be regenerated periodically. The condensation pipe 12 is cleaned by a heating device 8 to remove the condensate and possible dirt accumulated on the condensation pipe 12, so as to maintain good condensation effect. The heating device 8 can use an existing hot air device to achieve cleaning effect by sequentially blowing hot air into the air flow channel 100 and the condensation pipe 12.

[0055] The above description is only optional embodiments of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
