Description

Technical Field

[0001] The invention belongs to the technical field of drying devices, and in particular relates to a drying machine. Background Art

[0002] In order to dry food, tableware and other items, the traditional method is to place the items in a dry and ventilated place to evaporate the moisture on the items. This method has the following defects: 1. The drying speed is slow and the drying is not thorough, and sometimes some moisture will still remain; 2. Since the items are exposed to the outside, they are easily contaminated by dust during the drying process.

[0003] In order to facilitate the drying of items, people have designed dryers that can realize hot air circulation, such as the utility model patent with patent number ZL201320748708.6 "A food heating and drying cabinet using solar energy" (authorization announcement number CN203538299U), the utility model patent with patent number ZL201922138879.7 "An electric constant temperature drying box for food additive production" (authorization announcement number CN210952119U), and the utility model patent with patent number ZL201621135297.3 "A food drying device" (authorization announcement number CN206269552U). These public structures mostly include a box body, an air inlet and an air outlet arranged on the box body. External air enters the box body from the air inlet and is heated to dry the items inside the box body. The moisture in the items evaporates due to the heat, and the air in the box body becomes humid to form wet air, which is discharged from the air outlet.

[0004] Since the air discharged from the air outlet has high humidity and high temperature, if it is directly discharged from the dryer, the humidity and temperature of the indoor air will increase. When the humidity and temperature of the outside air itself are high, the discharged humid air will undoubtedly make the air more humid and hotter, thereby causing discomfort to the user. To overcome this defect, the prior art often achieves this by setting a condenser in the dryer to separate the discharged humid air into gas and liquid, thereby reducing the humidity and temperature of the discharged air. However, this method does not make good use of the heat of the high-temperature humid air itself, and there is a waste of energy. In addition, the setting of the condenser will undoubtedly increase the complexity of the structure of the dryer itself and the production cost.

[0005] At the same time, during the process of humid air being discharged from the air outlet, there is a situation in which the humid air flows back from the air outlet to the inside of the box, so that the humid air inside the box cannot be discharged well. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a dryer which can separate the gas and liquid of wet air without setting up a condenser in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a dryer, comprising: an inner liner and an outer shell, wherein the inner liner is a box structure having a drying chamber inside, and the outer shell is sleeved on the inner liner;

[0008] The invention is characterized in that: a gap connected to each other is left between the top wall of the outer shell and the top wall of the inner shell, and between the side wall of the outer shell and the side wall of the inner shell; an air outlet is provided on the top wall of the inner shell, and the air outlet connects the drying chamber and the gap; an exhaust port connected to the gap is provided on the bottom wall of the outer shell.

[0009] Furthermore, the air outlet is arranged on the edges of the left and right sides of the top wall of the inner container, and the openings of the air outlets on the left and right sides are respectively opposite to the left and right side walls of the outer shell. In this way, the humid air coming out of the air outlet can directly contact the side wall of the outer shell, thereby achieving gas-liquid separation, and the separated liquid flows down along the side wall of the outer shell. And the air outlet opposite to the side wall of the outer shell can prevent the humid air from flowing back. Of course, the air outlet can also be directly opened on the top wall of the inner container and opposite to the top wall of the outer shell.

[0010] In order to achieve that the air outlet is opposite to the side wall of the outer shell, preferably, a through hole is opened on the edge of the top wall of the inner tank, the edge of the through hole extends upward to form a first side wall, the through hole is covered with a baffle plate, the periphery of the baffle plate is connected to the top of the first side wall, and the side of the first side wall opposite to the side wall of the outer shell is open to form the above-mentioned air outlet.

[0011] Furthermore, there are a plurality of air outlets which are spaced apart along the front-to-back direction of the inner container.

[0012] In the above solution, in order to allow the gas after gas-liquid separation to be discharged smoothly, preferably, the exhaust port is located on the edges of the left and right sides of the bottom wall of the shell.

[0013] Preferably, there are a plurality of exhaust ports which are spaced apart along the front-to-back direction of the housing.

[0014] In the above scheme, the front side of the inner container has an opening, and the front side of the outer shell is provided with a door body for opening and closing the opening.

[0015] Finally, corresponding air inlets are provided on the backs of the outer shell and the inner container, and the air inlets are communicated with the drying chamber.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] By arranging an air outlet on the top wall of the inner liner and an exhaust port on the bottom wall of the outer shell, the humid air flowing out of the air outlet passes through the gap between the inner liner and the outer shell and is discharged from the exhaust port. The humid air flowing in the gap can achieve gas-liquid separation, thereby reducing the humidity of the air discharged from the exhaust port, and the condensed liquid can be discharged from the exhaust port.

[0018] The air flowing in the gap has a certain temperature. This air is located outside the inner tank and can transfer part of the heat to the inner tank, thereby achieving the effect of heat preservation and energy saving. It can also reduce the temperature of the exhaust air;

[0019] At the same time, the air outlet located on the top wall of the inner tank is conducive to the discharge of hot and humid air;

[0020] Furthermore, the present invention has a simple structure and is easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 8 As shown, a preferred embodiment of a dryer of the present invention is shown. The dryer comprises an inner liner 1 and an outer shell 2 sleeved on the inner liner 1 .

[0031] The inner container 1 is a box structure with a drying chamber 100 inside, and the outer shell 2 is sleeved on the inner container 1. There are interconnected gaps 200 between the left and right sides of the top wall of the outer shell 2 and the left and right sides of the top wall of the inner container 1, between the right side wall of the outer shell 2 and the right side wall of the inner container 1, and between the left side wall of the outer shell 2 and the left side wall of the inner container 1. A plurality of air outlets 10 are provided on the edges of the left and right sides of the top wall of the inner container 1. Each air outlet 10 is spaced apart along the front-to-back direction of the inner container 1 and connects the drying chamber 100 and the gap 200, so that the humid air in the drying chamber 100 is discharged into the gap 200. The left and right sides of the bottom wall of the outer shell 2 are respectively provided with exhaust ports 20 connected to the gap 200. There are a plurality of exhaust ports 20 and they are spaced apart along the front-to-back direction of the outer shell 2.

[0032] like Figure 2 , 3 As shown in FIGS. 5 and 7 , in this embodiment, the air outlet 10 located on the right side of the inner liner 1 is opposite to the right side wall of the outer shell 2, and the air outlet 10 on the left side of the inner liner 1 is opposite to the left side wall of the outer shell 2. The structure of each air outlet 10 is as follows: through holes 11 are opened on the edges of the left and right sides of the top wall of the inner liner 1, and the edges of the through holes 11 extend upward to form a first side wall 12. The upper part of the through holes 11 is covered with a baffle 13, and the periphery of the baffle 13 is connected to the top of the first side wall 12. The side of the first side wall 12 opposite to the side wall of the outer shell 2 is open to form the above-mentioned air outlet 10. The opening of the air outlet 10 is horizontal and opposite to the side wall of the outer shell 2, so that the humid air flowing out of the air outlet 10 can directly contact the side wall of the outer shell 2 to achieve preliminary gas-liquid separation, and then the humid air changes its flow direction and flows downward along the gap 200 between the side wall of the inner liner 1 and the side wall of the outer shell 2 to achieve further gas-liquid separation. The air and condensate after gas-liquid separation are discharged from the exhaust port 20. The horizontally opened air outlet 10 can prevent the moist air from flowing back into the drying chamber 100 along the air outlet 10 .

[0033] Meanwhile, in this embodiment, the front of the inner container 1 is open, and a door 3 for opening and closing the opening is provided on the front of the outer shell 2. Corresponding air inlets 4 are provided on the backs of the outer shell 2 and the inner container 1, and the air inlets 4 are connected to the drying chamber 100 to allow external air to enter the drying chamber 100.

[0034] The outside air enters the drying chamber 100 from the air inlet 4 and is heated to dry the articles in the drying chamber 100 . Then, the hot and humid air passes through the air outlet 10 and the gap 200 in sequence and is discharged from the exhaust port 20 .

[0035] A water receiving tray, a guide pipe and other structures may be provided below the exhaust port 20 to collect and discharge the condensed liquid.
