Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification, in particular to a dehumidifier. Background Art

[0002] Dehumidifiers are increasingly used in daily life. When the dehumidifier is working, the fan draws humid air into the machine, and the dehumidified air is discharged out of the machine after being condensed and dehumidified by the evaporator and heated by the condenser. This cycle keeps the indoor humidity within an appropriate range. However, the air duct layout in existing dehumidifiers mostly adopts the side air intake of centrifugal fans, and the evaporator and condenser are arranged on the air intake side of the centrifugal fan. However, the unilateral air intake means that the air intake surface cannot be placed against the wall, which greatly restricts the placement direction. Utility Model Content

[0003] The utility model aims to provide a dehumidifier to solve the technical problem that the existing dehumidifier has a single-side air inlet, so that the air inlet surface cannot be placed against the wall, which has a great restriction on the placement direction.

[0004] To solve the above-mentioned problems, the utility model provides a dehumidifier, including a box body and an evaporator, the evaporator is arranged in the box body and divides the internal space of the box body into an upper cavity and a lower cavity, the box body is provided with an air outlet on the box wall corresponding to the upper cavity, and a plurality of air inlets are provided on the box side wall corresponding to the lower cavity as the lower side wall area, the plurality of air inlets are arranged at intervals along the circumference of the lower side wall area, and the box side walls where at least two of the air inlets are located have different orientations; the upper cavity is provided with a wind drive component and a condenser, the wind drive component is used to drive the airflow from the air inlet to flow through the evaporator and the condenser and then flow to the air outlet.

[0005] In the dehumidifier provided by the utility model, the evaporator divides the internal space of the box into two approximately relatively independent upper and lower cavities. Correspondingly, the air inlet and the air outlet are blocked on both sides of the evaporator. The airflow entering the lower cavity through the air inlet needs to pass through the evaporator and condense and dehumidify it before entering the upper cavity and being discharged through the air outlet. On the one hand, the airflow flowing into the lower cavity under the driving action of the driving component can almost all be condensed and dehumidified with the evaporator, thereby improving the dehumidification effect of the evaporator and the dehumidifier; on the other hand, the flow channel of the airflow in the box is simple and the flow direction is single, and the degree of disturbance caused by the airflow backflow is low, thereby improving the flow smoothness of the airflow and reducing the disturbance of the airflow, and correspondingly further improving the dehumidification effect of the evaporator and the dehumidifier on the airflow.

[0006] In addition, multiple air inlets are dispersedly arranged along the circumference of the lower cavity, and at least two air inlets are located on the side walls of the box in different directions in the lower side wall area. When the dehumidifier is placed, even if the dehumidifier is placed against the wall, its multiple air inlets will not be blocked at the same time. The unblocked air inlets can take in air normally to ensure the normal operation of the dehumidifier, thereby reducing the occurrence of situations where the dehumidifier's air outlet has a single direction and is easily blocked, resulting in high restrictions on the placement orientation, thereby correspondingly improving the convenience and applicability of the dehumidifier.

[0007] Optionally, the box body is a rectangular body, and the air inlets are provided on the four side walls of the lower side wall area.

[0008] Optionally, the evaporator comprises a first evaporation plate section and a second evaporation plate section along the length direction or the width direction of the box body, and both the first evaporation plate section and the second evaporation plate section are arranged to be inclined downward in a direction toward each other.

[0009] Optionally, an included angle between the first evaporation plate segment and the second evaporation plate segment is 80° to 100°.

[0010] Optionally, the areas of the four side box side walls of the lower side wall area corresponding to the heights of the first evaporation plate section and the second evaporation plate section serve as air inlet areas, and each of the air inlet areas is provided with the air inlet.

[0011] Optionally, the four side walls of the box body are sequentially a first box side wall, a second box side wall, a third box side wall and a fourth box side wall along the circumferential direction thereof, wherein the top end of the first evaporation plate section corresponds to the first box side wall, and the top end of the second evaporation plate section corresponds to the third box side wall;

[0013] Optionally, each of the air inlet areas is provided with a plurality of grille holes which are arranged in parallel and at intervals, and the outer edge contours of all the grille holes located in the same air inlet area are similar to the outer edge contours of the corresponding air inlet area.

[0014] Optionally, the wind drive assembly includes a mounting frame arranged on the upper cavity, the mounting frame is provided with an axial flow fan, and both ends of the mounting frame abut against the condenser.

[0015] Optionally, the axial direction of the axial flow fan is consistent with the up-down direction, and the air outlet is located on the top wall of the box body.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Figure 1 FIG. 1 is a schematic diagram of the arrangement of a centrifugal fan 10', a condenser 20' and an evaporator 30' in a conventional dehumidifier. Figure 1As shown, the centrifugal fan 10' adopts lateral air inlet, and the condenser 20' and the evaporator 30' are both arranged on the air inlet side of the centrifugal fan 10'. Accordingly, the air inlet of the dehumidifier can only be set on the outside of the evaporator 30'. The single air inlet surface requires that when placing the dehumidifier, there must be no obstacles blocking one side of the air inlet surface, such as not being able to be against a wall, which leads to great restrictions on the placement of the dehumidifier.

[0025] In this regard, this embodiment provides a dehumidifier, such as Figure 2 As shown, it includes a box body 100 and an evaporator 200. The evaporator 200 is arranged in the box body 100 and divides the internal space of the box body 100 into an upper cavity 110 and a lower cavity 120. The box body 100 is provided with an air outlet 130 on the box wall corresponding to the upper cavity 110, and a plurality of air inlets 140 are provided on the box side wall corresponding to the lower cavity 120 as the lower side wall area. The plurality of air inlets 140 are arranged at intervals along the circumference of the lower side wall area, and the box side walls where at least two air inlets 140 are located have different directions; the upper cavity 110 is provided with a wind drive component 300 and a condenser 400. The wind drive component 300 is used to drive the airflow from the air inlet 140 to flow through the evaporator 200 and the condenser 400 and then flow to the air outlet 130.

[0026] When the dehumidifier provided in this embodiment is in operation, the driving component drives the external air flow to flow into the lower cavity 120 through the air inlet 140, and then flows upward through the evaporator 200 and enters the upper cavity 110. Subsequently, the air flow in the upper cavity 110 flows through the condenser 400 and is discharged from the air outlet 130; wherein, in the process of the air flow flowing through the evaporator 200, the water vapor carried therein can contact with the low-temperature evaporator 200 and condense into condensed water, thereby achieving dehumidification of the air flow; in the process of the dehumidified air flow subsequently flowing through the condenser 400, it can convect heat exchange with the condenser 400 to raise its temperature back to close to the indoor temperature, thereby reducing the change in the indoor ambient temperature caused by the operation of the dehumidifier.

[0027] Among them, in the dehumidifier provided in this embodiment, the evaporator 200 divides the internal space of the box body 100 into two approximately relatively independent upper cavities 110 and lower cavities 120. Correspondingly, the air inlet 140 and the air outlet 130 are blocked on both sides of the evaporator 200. The airflow entering the lower cavity 120 through the air inlet 140 needs to pass through the evaporator 200 and condense and dehumidify with it before it can enter the upper cavity 110 and be discharged through the air outlet 130. On the one hand, under the driving action of the driving component, the airflow flowing into the lower cavity 120 can almost all be condensed and dehumidified with the evaporator 200, thereby improving the dehumidification effect of the evaporator 200 and the dehumidifier; on the other hand, the flow channel of the airflow in the box body 100 is simple and the flow direction is single, and the degree of disturbance caused by the airflow backflow is low, thereby improving the flow smoothness of the airflow and reducing the disturbance of the airflow, and correspondingly further improving the dehumidification effect of the evaporator 200 and the dehumidifier on the airflow.

[0028] In addition, multiple air inlets 140 are dispersedly arranged along the circumference of the lower cavity 120, and at least two air inlets 140 are located on the side walls of the box in different directions in the lower side wall area. When the dehumidifier is placed, even if the dehumidifier is placed against the wall, its multiple air inlets 140 will not be blocked at the same time. The unblocked air inlets 140 can normally take in air to ensure the normal operation of the dehumidifier, thereby reducing the occurrence of the situation where the dehumidifier outlet 130 is in a single direction and is easily blocked, resulting in high restrictions on the placement orientation, thereby correspondingly improving the convenience and applicability of the dehumidifier.

[0029] Specifically, in this embodiment, Figure 2 As shown, the box body 100 is a rectangular body, and the four side walls of the lower side wall area are all provided with air inlets 140. The box body 100 of the dehumidifier is a rectangular body with a regular shape, which has higher processing accuracy and storage and placement convenience; the box body 100 is provided with air inlets 140 on all four sides, and the probability of the four side air inlets 140 being blocked when the box body 100 is placed is low, thereby ensuring the normal operation of the dehumidifier and further improving the convenience and applicability of the dehumidifier.

[0030] The number of air inlets 140 on a single side wall of the box is not limited; in other embodiments, the shape of the box body 100 can also be cylindrical or triangular.

[0031] In this embodiment, Figure 2 and Figure 3 As shown, the evaporator 200 includes a first evaporation plate section 210 and a second evaporation plate section 220 along the length direction or width direction of the box body 100, and both the first evaporation plate section 210 and the second evaporation plate section 220 are arranged to be inclined downward in a direction toward each other. First, the four box side walls of the rectangular box body 100 are the first box side wall 150, the second box side wall 160, the third box side wall 170 and the fourth box side wall 180 in sequence along its circumference, wherein the first box side wall 150 and the third box side wall 170 are arranged oppositely, and the direction from the first box side wall 150 to the third box side wall 170 is the length direction of the box body 100; the second box side wall 160 and the fourth box side wall 180 are arranged oppositely, and the direction from the second box side wall 160 to the fourth box side wall 180 is the width direction of the box body 100; the evaporator 200 0, the first evaporation plate section 210 and the second evaporation plate section 220 are arranged in sequence along the length direction or the width direction of the box body 100 to form a V-shaped structure. The first evaporation plate section 210 and the second evaporation plate section 220 are adapted to the shape of the box body 100 to be a regular rectangular flat plate structure. The regular shape has a higher airtightness for the partition in the box body 100, thereby improving the processing convenience and accuracy of the evaporator 200 and the convenience of assembly with the box body 100, and can also ensure the singleness of the airflow direction and reduce the adverse effects of airflow disturbance on the dehumidification effect.

[0032] Secondly, the first evaporation plate section 210 and the second evaporation plate section 220 are in a V-shaped structure, both of which are in the form of an inclined guide slope. On the one hand, compared with the evaporator 200 in the form of a horizontal plate, the evaporator 200 in this embodiment has a larger effective dehumidification area and a higher dehumidification capacity for the airflow, thereby improving the dehumidification effect of the dehumidifier; on the other hand, the condensed water formed by the condensation of the airflow on the first evaporation plate section 210 and the second evaporation plate section 220 can converge along the corresponding plate sections to the connection between the two plate sections, and the linear corners at the lowest ends of the first evaporation plate section 210 and the second evaporation plate section 220 serve as the convergence point of the condensed water to drip downward, thereby improving the convergence of the evaporator 200 dripping downward, ensuring that the water receiving pan can receive the condensed water, and reducing the occurrence of a large water receiving pan area required for the evaporator 200 to drip downward as a whole and easily drip outward.

[0033] Specifically, in this embodiment, the included angle between the first evaporation plate section 210 and the second evaporation plate section 220 is 80° to 100°, preferably 90°.

[0034] Specifically, a water receiving pan may be provided in the lower cavity 120, and the water receiving pan is received below the connection between the first evaporation plate section 210 and the second evaporation plate section 220. Condensed water formed on the first evaporation plate section 210 and the second evaporation plate section 220 can flow downward and converge at the lower end corners of the two. The condensed water can be received by using a water receiving pan with a smaller area, which has a simple structure and occupies less space in the lower cavity 120, thereby providing more accommodation space for the water tank and the compressor.

[0035] In this embodiment, Figure 2 and Figure 3 As shown, the areas of the four side box side walls of the lower side wall area corresponding to the heights of the first evaporation plate section 210 and the second evaporation plate section 220 serve as air inlet areas, and each air inlet area is provided with an air inlet 140 . Specifically, the top of the first evaporation plate section 210 corresponds to the first box side wall 150, and the top of the second evaporation plate section 220 corresponds to the third box side wall 170. Within the height range of the first evaporation plate section 210 and below the first evaporation plate section 210, the first box side wall 150 forms a rectangular first air inlet area, the second box side wall 160 forms a triangular second air inlet area 161, and the fourth box side wall 180 forms a triangular third air inlet area; within the height range of the second evaporation plate section 220 and below the second evaporation plate section 220, the third box side wall 170 forms a rectangular fourth air inlet area 171, the second box side wall 160 forms a triangular fifth air inlet area 162, and the fourth box side wall 180 forms a triangular sixth air inlet area, and all six air inlet areas are provided with air inlets 140.

[0036] On the one hand, the first air inlet area, the second air inlet area 161 and the third air inlet area are arranged on one side of the inclined first evaporation plate section 210. The airflow entering through the air inlet 140 of the first air inlet area, the second air inlet area 161 and the third air inlet area can reach the first evaporation plate section 210 from all directions at a shorter distance, and flow into the upper cavity 110 after condensation and dehumidification with the first evaporation plate section 210. The airflow can ensure contact condensation with various areas of the first evaporation plate section 210 and ensure the effectiveness of the entire area of ​​the first evaporation plate section 210. In addition, the flow path of the airflow is shorter and the probability of disturbance is lower, thereby further ensuring the dehumidification effect of the first evaporation plate section 210. Similarly, the air inlets 140 of the third air inlet area, the fourth air inlet area 171 and the fifth air inlet area 162 are arranged on one side of the second evaporation plate section 220, and the airflow flowing in through the air inlets 140 of the third air inlet area, the fourth air inlet area 171 and the fifth air inlet area 162 can also ensure contact condensation with various areas of the second evaporation plate section 220 and ensure the effectiveness of the overall area of ​​the second evaporation plate section 220, and the flow path of the airflow is shorter and the probability of disturbance is lower, which can further ensure the dehumidification effect of the second evaporation plate section 220.

[0037] On the other hand, an air inlet 140 is provided in an air inlet area at a height corresponding to the first evaporation plate section 210 and the second evaporation plate section 220. On the basis of ensuring that the air inlet area of ​​the air inlet 140 and the airflow entering through the air inlet 140 are effectively contacted and condensed with the entire area of ​​the first evaporation plate section 210 and the second evaporation plate section 220, the space enclosed by the area of ​​the lower side wall area below each air inlet area is larger, which can ensure the accommodation of the water receiving tray, the water tank and the compressor. At the same time, when the volume of the water receiving tray, the water tank and the compressor is determined, the volume of the entire lower cavity 120 is smaller, and accordingly, the overall volume of the dehumidifier is smaller, thereby improving the compactness of the dehumidifier and reducing its occupied space on the basis of ensuring the dehumidification effect of the dehumidifier.

[0038] Specifically, in this embodiment, Figure 2 As shown, each air inlet area is provided with a plurality of parallel and spaced grille holes 141, and the outer edge contours of all grille holes 141 located in the same air inlet area are similar to the outer edge contours of the corresponding air inlet area. In each air inlet area, a plurality of parallel and spaced grille holes 141 are provided as air inlets 140, and the length of each grille hole 141 is adapted to the edge of the air inlet area, so that the contours surrounded by the outer edges of the plurality of grille holes 141 are similar to the outer edge contours of the air inlet area, which not only makes the arrangement area of ​​the air inlet 140 in the corresponding air inlet area more comprehensive and the area of ​​the air inlet 140 larger, thereby ensuring the air intake of the dehumidifier; the grille bars formed between two adjacent grille holes 141 can also play a role in blocking debris and children, thereby improving the safety and stability of the dehumidifier.

[0039] Optionally, in this embodiment, if Figure 3 As shown, the wind driving component 300 includes a mounting frame 310 arranged on the upper cavity 110, and the mounting frame 310 is provided with an axial flow fan 320. This is one of the specific forms of the driving component. When in operation, the axial flow fan 320 starts to drive the airflow; wherein, the axial flow fan 320 specifically includes a driving motor 321 installed on the mounting frame 310 and an axial flow fan blade 322 fixed to the driving end of the driving motor 321. The axial flow fan 320 is selected as the wind driving source, and the upper cavity 110 surrounded by the box body 100 and the evaporator 200 is also used as the air duct of the axial flow fan 320. There is no need to set up an additional shell to surround the air duct of the driving component. The structure is simpler, the space occupied by the upper cavity 110 is smaller, and the restrictions on the orientation of the air inlet 140 and the air outlet 130 are smaller, thereby improving the processing convenience of the dehumidifier and reducing its cost.

[0040] The mounting bracket 310 may specifically abut against the condenser 400 , and the mounting bracket 310 and the evaporator 200 may limit the condenser 400 at the upper and lower sides thereof, thereby improving the installation position stability of the condenser 400 .

[0041] Specifically, the axial direction of the axial flow fan 320 is consistent with the up-down direction, and the air outlet 130 is located on the top wall of the box body 100. When the axial flow fan 320 is in operation, it can drive the external airflow to flow into the lower cavity 120 through the air inlets 140 around the lower cavity 120, and the airflow then turns to flow from bottom to top through the evaporator 200, and the airflow flowing upward into the upper cavity 110 can directly flow upward through the air outlet 130 at the top without turning, the airflow path is simple and smooth, and the disturbance is small, which can improve the air supply and dehumidification effect of the dehumidifier; in addition, the air outlet 130 is set on the top wall, and the probability of the air outlet 130 being blocked when the dehumidifier is placed is smaller, thereby further reducing the restrictions on the placement of the dehumidifier, and correspondingly further improving the convenience of using the dehumidifier.

[0042] Of course, in some other embodiments, the air outlet 130 may also be located on the side cavity wall of the upper cavity 110 .

[0043] In this embodiment, Figure 2 and Figure 3As shown, the condenser 400 is stacked above the evaporator 200. The shapes and sizes of the condenser 400 and the evaporator 200 are approximately the same. The condenser 400 is stacked above the evaporator 200 with a gap between them. The airflow passing through the evaporator 200 and being cooled needs to pass through the condenser 400 before it can flow upward to the air outlet 130, so that the airflow can fully react with the condenser 400 to achieve temperature recovery, and correspondingly reduce the impact of the dehumidifier on the indoor ambient temperature; in addition, the condenser 400 and the evaporator 200 are stacked, and the space occupied is small, so as to ensure the installation of the wind driving component 300 and reduce the volume of the upper cavity 110, thereby further reducing the space occupied by the box 100 and the dehumidifier, and improving its convenience of use.
