[0002] In order to achieve heating and drying of materials or attachments on the surface of materials, most of the drying equipment currently used obtains thermal energy through electric heating, such as using electric heating components such as electric heating tubes or electric heating rods to heat and dry materials or attachments on the surface of materials.

[0003] This type of drying equipment has the following main problems in actual use:

[0004] First, it mainly relies on the conversion of electrical energy to directly obtain heat energy, which consumes a lot of electricity and is not energy-saving, environmentally friendly, or power-saving;

[0005] Second, after electric heating, the overall temperature of the equipment is relatively high. As the use time increases, it affects the external ambient temperature, and the workshop will become even hotter in summer.

[0006] In some special working conditions, especially the heating and drying of materials on the continuously running conveyor belt on the production line or the attachments on the surface of the materials, such as the need to dry the glue used in the shoemaking process, it is also necessary to optimize and improve the structure and layout of the heating and drying equipment to adapt to the heating and drying of the production line.

In general, it has the following significant beneficial effects:

[0030] 1. The unit includes a first chamber body and a second chamber body, and the first chamber body constructs a tunnel-type heating and drying channel. Through the setting of the tunnel-type heating and drying channel, the materials entering the tunnel-type heating and drying channel or the attachments on the materials can be dried. The existing production line has a conveyor belt, which can continuously transport materials. Therefore, the materials can enter the tunnel-type heating and drying channel from one end to be dried, and can be transported out from the other end by the conveyor belt after drying.

[0031] 2. The utility model utilizes the setting of the circulation system, and the refrigerant circulates in the circulation system. Through the setting of each fan, a circulation system similar to air conditioning is formed, and two air circulations are formed, one is the circulation circulation of the gas in the first chamber and the tunnel-type heating and drying channel, and the other is the circulation circulation of the gas in the second chamber and the external environment. The two circulations do not interfere with each other, which effectively improves the energy efficiency of the whole machine;

[0032] 3. The whole machine can realize energy conversion through the change of the gas-liquid state of the refrigerant itself, such as forming hot air to heat and dry materials, forming cold air to obtain the air conditioning effect in summer, and finally reducing the external environment, such as the temperature of the workshop; for this beneficial effect, compared with the existing mode of using electric heating to obtain thermal energy, it is obvious that the utility model has particularly obvious advantages in terms of energy saving, environmental protection and power saving, and the energy efficiency of the whole machine is also significantly improved;

[0033] 4. In the second chamber, the water vapor in the external environment gas will condense into water droplets after passing through the cold evaporator together with the external environment gas, which can effectively reduce the humidity of the cold air. When the low-humidity cold air is discharged into the external environment, the humidity of the external environment gas is reduced. Especially in the rainy season, the air humidity is reduced, which makes it easier to heat and dry, save energy and electricity, and the effect is very obvious;

[0034] 5. The unit can be constructed as an integrated type or a split type. When constructed as an integrated type, it can be placed as a whole on the support frames on both sides of the conveyor belt of the production line, so that the unit can be placed as a whole and moved away from the production line without changing or destroying the production line; when constructed as a split type, the first chamber can be placed on the support frames on both sides of the conveyor belt of the production line, and the second chamber can be selectively placed according to the on-site working conditions, such as placed on the top of the first chamber, or placed on the foundation beside the production line, or suspended. It can be seen that the split structure has a variety of placement options for the second chamber, and the first chamber and the second chamber are separated to form a separate chamber, which can reduce weight during transportation or placement, and facilitate transportation and placement operations, especially when the second chamber is not placed on the top of the first chamber, the weight placed on the support frame can be reduced. More importantly, when the chamber needs to be repaired, the corresponding chamber can be disassembled and repaired separately. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0047] The main idea of ​​this utility model is to use the working principle similar to that of air conditioners to construct an electric heating mode that is completely different from the existing mainstream heating and drying, that is, to directly convert electrical energy into thermal energy, thus forming a very energy-saving, environmentally friendly, power-saving, and cooling and dehumidifying heating and drying concept. Of course, it is not a simple application, but a new structure of tunnel-type heating and drying equipment is constructed by drawing on the working principle of air conditioners to adapt to the heating and drying of materials on the conveyor belt of the continuous operation of the production line.

[0048] The specific concept of the utility model is mainly to set up a circulation system including an evaporator, a compressor, a condenser and a throttling element, so that the refrigerant circulates in the circulation system, and when passing through the evaporator and the condenser, heat exchange occurs with the air around the evaporator and the condenser, so that the temperature of the gas around the body changes, and through a specific structure, such as the setting of the second chamber body and the first chamber body, the first chamber body constructs a tunnel-type heating and drying channel, and the condenser is arranged in the first chamber body, and the evaporator is arranged in the second chamber body, thereby obtaining corresponding hot air and low-humidity cold air, and the hot air is blown to the materials entering the tunnel-type heating and drying channel under the action of the condensing fan to heat and dry the materials or the attachments on the surface of the materials, and the low-humidity cold air enters the external environment under the action of the evaporating fan, providing a refrigeration effect similar to that of air conditioning. It should be noted that the various circulation components of the circulation system, such as the evaporator, the compressor, the condenser and the throttling element, are connected through pipelines, and after the connection, the circulation system as a whole circulates with refrigerant.

[0049] The following will be combined with the accompanying drawings to clearly describe the technical solutions in the specific embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the following embodiments are within the scope of protection of the utility model.

[0050] Embodiment 1

[0051] See also Figure 1-Figure 5 In this embodiment, the tunnel type heating and drying equipment of the utility model is used in a production line, and the production line includes a conveyor belt 3 and a support frame 4 located on both sides of the conveyor belt 3. In this embodiment, the tunnel type heating and drying equipment includes a unit 100 and a circulation system arranged therein. The unit 100 includes a first chamber body 1 and a second chamber body 2 which are arranged separately, wherein the components of the circulation system are correspondingly arranged in the first chamber body 1 and the second chamber body 2, and the two chamber bodies and the circulation system are combined to form the tunnel type heating and drying equipment.

[0052] In the present embodiment, the unit 100 is a split structure, and the first chamber body 1 and the second chamber body 2 are separately arranged, and the first chamber body 1 and the second chamber body 2 are connected by the pipeline of the circulation system. When in use, the first chamber body 1 and the second chamber body 2 can be transported and placed separately, which can effectively reduce the carrying weight. In particular, during maintenance, the first chamber body 1 and the second chamber body 2 can be disassembled separately, that is, when the corresponding chamber body is disassembled, the other chamber body will not be affected, which greatly facilitates the disassembly and maintenance. And when placed, the second chamber body 2 can be placed on the top of the first chamber body 1, or it can be placed on the foundation beside the production line, and it can even be suspended. It can be seen that the placement method of the second chamber body 2 is diverse, and it can be adaptively selected according to on-site needs. In the present embodiment, the second chamber body 2 is preferably placed on the foundation beside the production line, see Figure 1 .

[0053] In the embodiment of the present invention, the circulation system includes components such as a compressor (not marked), a condenser 5, a throttling element (not marked) and an evaporator 6 connected by pipelines. The refrigerant circulates in the circulation system. Under the action of the compressor, the refrigerant exchanges heat with the surrounding gas of the device body when flowing through the evaporator 6 and the condenser 5, and the refrigerant changes from gas to liquid state, thereby realizing energy conversion.

[0054] In this embodiment, the refrigerant is Freon commonly used in air conditioners. Among many refrigerants, its cooling (heat) efficiency is very significant, thereby ensuring the excellent effect of the tunnel dryer in energy saving, environmental protection and electricity saving.

[0055] In this embodiment, the conveyor belt 3 can run continuously to transport materials. It should be noted that the continuous operation means that the conveyor belt 3 can smoothly and uninterruptedly transport the materials placed thereon when it needs to run continuously. Of course, when it needs to stop, or when it needs to stop for a period of time, it can also stop running for the required time, which does not contradict the continuous operation.

[0056] In this embodiment, the support frame 4 is a frame fixedly arranged on both sides of the conveyor belt 3, and has a load-bearing top (not marked), through which the first chamber body 1 can be supported. It should be noted that the load-bearing top of the support frame 4 is basically flush with the conveyor belt 3, so after being placed, the first chamber body 1 is erected on the conveyor belt 3 to form a tunnel-type heating and drying channel 200 adapted to the conveyor belt 3. Adapting to the conveyor belt 3 here can be understood as: the width of the tunnel-type heating and drying channel 200 matches the width of the conveyor belt 3, and will not be too wide or too narrow; the tunnel-type heating and drying channel 200 has a certain height, and will not be very low to hinder the transportation of materials on the conveyor belt 3; the tunnel-type heating and drying channel 200 has an appropriate length, which will not be too short to affect the amount of materials entering it for drying treatment, and will not be too long to increase the cost. Among them, the tunnel-type heating and drying channel 200 can be understood as a structure similar to a tunnel, with two open ends and a channel in the middle.

[0057] In this embodiment, the first chamber body 1 is arranged as a whole along the material conveying direction, including a top chamber body 7 and a first side chamber body 8 and a second side chamber body 9 respectively connected to the two ends of the top chamber body 7 vertically, so that the first chamber body 1 as a whole is somewhat similar to an inverted U-shape, and the space surrounded by the concave part of the first chamber body 1 constitutes the tunnel-type heating and drying passage 200. It can be seen that the left side of the tunnel-type heating and drying passage 200 is the first side chamber body 8, the right side is the second side chamber body 9, and the top is the top chamber body 7. The first side chamber body 8 and the second side chamber body 9 can be used to be placed on the load-bearing top of the support frame 4. The left and right directions are as follows: Figure 5 The left and right directions are used as reference.

[0058] In this embodiment, the load-bearing top of the support frame 4 has a flat top surface, and the first side chamber body 8 and the second side chamber body 9 have a placement bottom. The placement bottom constructs a flat bottom surface, and the size and shape of the bottom surface are basically compatible with the top surface. In addition, the top surface is symmetrically arranged on both sides of the conveyor belt 3. Therefore, after the first chamber body 1 is placed, the overall placement is stable and reliable, and it will not be easily displaced even under the action of external force unless a lifting operation is performed.

[0059] On the basis of the above, with regard to the specific structure of the first chamber body 1, in this embodiment: the first chamber body 1 as a whole is composed of three parts, namely, the first side chamber body 8 and the second side chamber body 9 which are symmetrically arranged on the left and right, and the top chamber body 7 which connects the chamber bodies on both sides. After the first chamber body 1 is firmly placed on the production line, the top chamber body 7 spans over the conveyor belt 3 and its length direction is arranged along the material conveying direction, while the chamber bodies on both sides are respectively placed on the support frame 4 on both sides of the conveyor belt 3 and their length directions are also consistent with the material conveying direction.

[0060] In this embodiment, the first chamber 1 is provided with a condensing fan and a condenser 5 of a circulation system. As for the selection of the condenser 5, a fin-type condenser with excellent heat exchange effect is adopted. As for the condensing fan, it is arranged in the first side chamber 8, preferably a cross-flow fan 10, which is mainly adapted to be installed in the first side chamber 8 of the present invention which is not high and relatively narrow and long. At the same time, the outlet of the cross-flow fan 10 is basically designed as an elongated hole, which can form a strong and uniform air supply effect, which can effectively meet the applicable scenarios of the present invention and can effectively improve the drying effect.

[0061] In this embodiment, the condenser 5 and the condensing fan are arranged as follows: the condenser 5 is obliquely laid at the intersection of the first side chamber 8 and the top chamber 7 along the length direction of the first chamber body 1. It can be seen that the condenser 5 obliquely laid near the intersection can obtain a larger air inlet side than the condenser laid flat (i.e. horizontally), which can effectively increase the heat exchange amount and improve the heat exchange rate, thereby improving the heating and drying energy efficiency. It should be noted that laying can be understood as the air inlet side of the condenser 5 is not in an upright state, but is horizontal or slightly inclined at a certain angle relative to the horizontal. If it is horizontal, it can be understood as flat laying, and if it is inclined at a certain angle, it can be understood as oblique laying.

[0062] The condensing fan, i.e., the crossflow fan 10, is disposed below the condenser 5 and in the first side chamber 8, and the top of the condenser 5 is slightly lower than the inner corner of the intersection. Thus, the crossflow fan 10 is directly disposed close to the condenser 5, so that the hot air around the condenser 5 can be quickly and directly sucked into the crossflow fan 10.

[0063] In this embodiment, two condensers 5 and two crossflow fans 10 are respectively provided, and the two condensers 5 are arranged linearly one after the other along the length direction of the first chamber body 1. The same two crossflow fans 10 are arranged below the corresponding condensers 5, and the whole is also arranged linearly one after the other along the length direction of the first side chamber body 8. After the two condensers 5 and the two corresponding crossflow fans 10 are provided, the heat exchange amount is doubled compared with the provision of one, thereby obtaining double hot air, and the heating and drying effect is significantly improved.

[0064] In order to realize the circulation of gas in the first chamber body 1, an air outlet 11 is provided on the inner wall of the first side chamber body 8 to blow hot air to the tunnel-type heating and drying channel 200, and an air inlet 12 is provided on the inner wall of the second side chamber body 9 to allow the gas in the tunnel-type heating and drying channel 200 to enter the second side chamber body 9. After the incoming gas flows through the condenser 5 to form hot air, it is transported to the tunnel-type heating and drying channel 200 through the air outlet 11 by the cross-flow fan 10. This cycle is repeated to form a one-way circulation of gas. It can be seen that during the circulation process of the one-way circulation of gas, there will be no collision of opposing gases, no turbulence, reduced losses, smooth and rapid gas circulation, significant heating and drying effects, and significantly increased energy efficiency of the whole machine.

[0065] The principle of forming hot gas is as follows: when the refrigerant Freon flows through the condenser 5, heat exchange occurs with the gas around the condenser 5, the refrigerant Freon changes from gas to liquid, releasing heat energy, and the gas around the condenser 5 absorbs heat and becomes hotter, forming the hot gas.

[0066] In this embodiment, the air outlet 11 is arranged near the lower part or bottom of the first side chamber body 8, and the air inlet 12 is arranged near the lower part or bottom of the second side chamber body 9 and is arranged correspondingly to the air outlet 11, so that the hot air can enter the second side chamber body 9 after heating and drying the material or the attachments on the material. After further optimization, the air outlet 11 is arranged correspondingly to the outlet of the crossflow fan 10, and after the corresponding arrangement, it is an elongated hole adapted to the outlet of the crossflow fan 10. In this embodiment, the outlet end of the crossflow fan 10 is directly assembled in the air outlet 11, so that the hot air directly enters the tunnel-type heating and drying channel 200 from the outlet of the crossflow fan 10. Further, the air inlet 12 is arranged correspondingly to the air outlet 11, and is also an elongated hole. The elongated hole-shaped arrangement can form a strong and uniform air supply or air intake effect.

[0067] In this embodiment, the hot air is blown to the tunnel-type heating and drying channel 200 through the air outlet 11. Since the air outlet 11 is arranged near the bottom or near the bottom, it can be blown to the material on the conveyor belt 3 at a close distance and quickly. The material or the attachments on the material are heated and dried accordingly, such as drying the material itself or the glue, ink, paint, electroplating layer on the surface of the material. It can be seen that in the process of gas circulation, a one-way reciprocating circulation is formed to avoid the formation of turbulence, which effectively improves the energy efficiency of the whole machine.

[0068] For further optimization and improvement of the first chamber body 1, in this embodiment, a first guide plate 13 is provided in the second side chamber body 9 to guide the gas entering the second side chamber body 9 through the air inlet 12, and the first guide plate 13 extends along the length direction of the second side chamber body 9. It should be noted that the first guide plate 13 is a plate body with an inward concave arc shape as a whole, and the inward concave arc surface of the plate body is used to guide the gas, so that the gas quickly and smoothly enters the second side chamber body 9. At the same time, a second guide plate 14 is also provided at the intersection of the top chamber body 7 and the second side chamber body 9 to guide the gas entering the top chamber body 7 from the second side chamber body 9, and the second guide plate 14 extends along the length direction of the top chamber body 7. The second guide plate 14 is also a plate body with an inward concave arc shape as a whole, and the inward concave arc surface of the plate body is used to guide the gas, so that the gas quickly and smoothly enters the top chamber body 7. In terms of layout, the first guide plate 13 and the second guide plate 14 are symmetrically arranged up and down, and the circulating gas is guided one by one.

[0069] It should be noted that, in this embodiment, the top and bottom of the top chamber body 7 form a closed plate body, and the two ends of the top chamber body 7 are respectively connected to the first side chamber body 8 and the second side chamber body 9. In addition, the air outlet 11 and the air inlet 12 are only provided on the inner side walls of the first side chamber body 8 and the second side chamber body 9, respectively, so that a one-way gas circulation can be formed.

[0070] In this embodiment, the number of air outlets 11 provided on the first side chamber body 8 is two, the number of air inlets 12 provided on the second side chamber body 9 is also two, the inner side wall of the first side chamber body 8 between adjacent air outlets 11 forms a continuous plate body, and the inner side wall of the second side chamber body 9 between adjacent air inlets 12 also forms a continuous plate body. With this arrangement, the phenomenon of gas cross-flow caused by opening other holes on the inner side wall is avoided, and the gas can be concentrated from the air outlet and concentrated from the air inlet.

[0071] In this embodiment, the second chamber body 2 is placed on the foundation beside the production line and connected to the first chamber body 1 through the pipeline of the circulation system. It should be noted that the connection here refers to the circulation components in the circulation system, such as the connection between the compressor, the condenser 5, and the evaporator 6 by pipeline. In this embodiment, the second chamber body 2 is provided with an evaporation fan 15 and the evaporator 6, the compressor and other components of the circulation system, wherein the evaporator 6 is a finned evaporator. In this embodiment, the evaporator 6 is provided with one, and the evaporator 6 is arranged upright and constitutes a part of the outer side of the second chamber body 2 extending along the length direction. In this embodiment, the evaporation fan 15 is provided in plurality, and is arranged at intervals on the top of the second chamber body 2 along the length direction of the second chamber body 2, and most of them are located in the second chamber body 2, and its outlet faces inward and the inlet faces outward, so that the second chamber body 2 is roughly rectangular and regular as a whole.

[0072] When the refrigerant Freon flows through the evaporator 6, it exchanges heat with the air around the evaporator 6, changing from liquid to gas, absorbing the heat of the surrounding air, causing the temperature of the surrounding air to drop. In the process of lowering the temperature of the surrounding air, condensed water is generated, thereby reducing the humidity of the surrounding air. Low-humidity cold air is formed under the action of the evaporating fan 15 and flows from the fin part of the evaporator 6 to the external environment, thereby reducing the humidity and temperature of the external environment air and obtaining a cooling effect similar to that of air conditioning.

[0073] In this embodiment, the evaporation fan 15 can be a centrifugal fan or an axial flow fan. In this embodiment, a centrifugal fan is preferred. Under the action of the evaporation fan 15, the external environment gas flows to the evaporator 6, and undergoes heat exchange with the refrigerant Freon in the evaporator 6 to become cold air. The cold air enters the second chamber 2 and finally enters the evaporation fan 15, and is discharged to the external environment from the air outlet of the evaporation fan 15. The external environment gas will circulate through the evaporator 6 under the action of the evaporation fan 15 to form cold air. Therefore, under the action of the evaporation fan 15, a one-way gas circulation is formed between the second chamber 2 and the external environment, and the gas circulation is smooth, fast, no turbulence is generated, and the refrigeration effect is good. Of course, in other embodiments, the external environment gas can also flow from the evaporation fan 15 into the second chamber 2, and then pass through the evaporator 6 to become cold air and be discharged to the external environment. Of course, in this embodiment, it is preferred that the cold air is discharged from the evaporating fan 15 to the external environment, which can effectively increase the speed and efficiency of discharging the cold air, and at the same time increase the amount of gas that undergoes heat exchange with the evaporator 6 per unit time.

[0074] Especially in the hot summer, after adopting the tunnel type heating and drying equipment of the utility model, on the one hand, energy-saving, environmentally friendly and electricity-saving heating and drying effects can be obtained, and on the other hand, the workshop is equivalent to installing air conditioning, and the comfort level is much better than that of the workshop adopting the existing drying equipment that directly converts electrical energy into thermal energy.

[0075] In this embodiment, for further optimization and improvement, a water receiving trough 16 is provided at the bottom of the evaporator 6 of the second chamber body 2, and the condensed water received by the water receiving trough 16 is discharged from the device through the arranged water pipe, thereby preventing the condensed water from flowing around inside the device. It should be noted that in the second chamber body 2, the water vapor in the external environment gas will condense into water droplets after passing through the cold evaporator 6 (the refrigerant needs to absorb a large amount of heat for gasification, and the evaporator 6 will also absorb heat and become cold) together with the external environment gas, and the water droplets can be discharged from the water receiving trough 16. It can be seen that the humidity of the cold air can be effectively reduced in this embodiment. When the low-humidity cold air is discharged into the external environment, the humidity of the external environment gas is reduced, especially in the rainy season, the air humidity is reduced, it is easier to heat and dry, it is more energy-saving and power-saving, and the effect is very obvious.

[0076] In this embodiment, one side of the second chamber body 2 along the width direction is configured as an electric control operation room 17, and the electric control operation room 17 is configured with an operation panel (not marked) for realizing control operations. A mesh plate 18 is provided on the outer side of the evaporator 6, and a wind chamber 19 is configured between the mesh plate 18 and the evaporator 6. The optimized design of this structure, on the one hand, the mesh plate 18 can protect the evaporator 6, and at the same time, after the wind chamber 19 is set, the external environment gas will not mix with the cold air in the second chamber body 2 after entering the wind chamber 19.

[0077] Through the structure of the second chamber 2 and the fact that the second chamber 2 can discharge cold air to the external environment, the compressor and other components of the circulation system can be arranged in the second chamber 2, and the electronic control components can be arranged next to the second chamber 2 to obtain a suitable temperature and avoid excessive temperature affecting the performance of each component.

[0078] In this embodiment, cold air can be discharged directly from the second chamber 2 to the external environment to effectively improve the temperature of the external environment.

[0079] The unit 100 in this embodiment is a split structure, and the second chamber 2 and the first chamber 1 can be transported and placed separately, and can also be disassembled and repaired separately without affecting each other. In addition, the first chamber 1 can be directly placed and fixed on the support frame 4 on both sides of the conveyor belt 3, and form a tunnel-type heating and drying channel 200, thereby achieving heating and drying of materials on the conveyor belt or attachments on the materials.

[0080] The production line tunnel drying system in this embodiment forms two non-turbulent one-way circulating gas flows, namely, a non-turbulent one-way circulating flow between the first chamber 1 and the gas in the tunnel-type heating and drying channel 200, and a non-turbulent one-way circulating flow between the second chamber 2 and the external environment gas. This avoids the formation of turbulence, improves the smoothness of gas flow, effectively improves the heating and drying efficiency, and ultimately improves the energy efficiency of the entire machine.

[0081] Embodiment 2

[0082] refer to Figure 6-Figure 8 , which is different from the first embodiment, the unit 100 is an integrated structure and can be transported and placed independently of the production line. Therefore, the production line can be set up independently of the unit 100, especially the conveyor belt 3, which does not need to be set up in the unit 100, so that not only the internal structure of the unit 100 can be simplified, but also the overall volume of the unit 100, especially the height of the unit 100, can be effectively reduced.

[0083] The second chamber 2 of the unit 100 is disposed on the top of the first chamber 1 and the two are separated by a partition (not shown) to form a cold and hot isolation to improve the energy efficiency of the whole machine. In this embodiment, the partition is both a part of the top plate of the first chamber 1 and the bottom plate of the second chamber 2.

[0084] Specifically: the second chamber body 2 is offset at the top of the tail end of the first chamber body 1, and extends from one end to the other end along the width direction of the top of the first chamber body 1; the first chamber body 1 and the second chamber body 2 are configured to form the unit 100 which is L-shaped in a side view, and the unit 100 can be placed as a whole on the load-bearing top of the support frame 4 through the two side chamber bodies of the first chamber body 1.

[0085] Embodiment 3

[0087] Embodiment 4

[0088] Different from the first embodiment, in this embodiment, the top chamber 7 or the second side chamber 9 is selected to set the condenser 5. At this time, the condenser 5 can be set vertically or obliquely. Compared with the first embodiment, the condenser 5 is far away from the cross-flow fan 10, and there is a certain loss of hot air during the circulation process.

[0089] Embodiment 5

[0090] Different from the first embodiment, a crossflow fan 10 is also provided in the second side chamber 9, and the inlet of the crossflow fan 10 is provided corresponding to the air inlet 12. Compared with the first embodiment, the addition of the crossflow fan 10 can accelerate the gas circulation effect, but increases the number of assembled parts, and the addition of the crossflow fan 10 increases the production cost.

[0091] Embodiment 6

[0092] Different from the first embodiment, the condenser 5 is arranged as follows, and the condenser 5 is arranged at a distance in the width direction of the first chamber body 1, including but not limited to the following arrangement:
