Description

Technical Field

[0001] The utility model relates to the technical field of electric control boxes, in particular to an anti-condensation device and an air conditioning unit. Background Art

[0002] During the operation of the air conditioning system, the air conditioning unit will experience a variety of operating conditions according to different actual needs. Under these different operating conditions, the load and heat generation of the electrical components will change. Especially under high-load operating conditions, the electrical components will generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, the temperature of the electrical components will be too high, thus affecting their normal operation and life.

[0003] However, in some specific application scenarios, air conditioning units have higher requirements for the protection level of the electric control box. Such high-protection-level electric control boxes usually have better airtightness to ensure their reliability and safety in harsh environmental conditions. But this also brings a problem: due to the relative airtightness of the internal space of the electric control box, when the ambient temperature is low, the temperature difference between the inside and outside of the electric control box is large, which easily leads to condensation in the cabinet. This condensation not only affects the normal operation of electrical components, but also may pose a threat to the electrical safety performance of the product.

[0004] In hot and humid areas, the climate environment has stricter requirements on the heat dissipation and anti-condensation of the electric control box. Although the traditional air-cooled heat dissipation device can solve the heat dissipation problem to a certain extent, it is difficult to apply it directly due to the airtightness requirements of the high protection level electric control box. At the same time, although the installation of conventional drainage pipes can discharge the condensation water in the cabinet, it may also cause hot and humid air to enter the electric control box, thus failing to meet the protection level requirements.

[0005] Therefore, for electric control boxes with a higher protection level, how to ensure their heat dissipation performance under high load conditions and effectively prevent condensation in low temperature environments has become an urgent problem to be solved. Utility Model Content

[0013] Furthermore, the middle portion of the liquid guiding tube is U-shaped or V-shaped.

[0014] Furthermore, the liquid guide tube includes a sealing section and a liquid storage section. The middle part of the liquid guide tube is the liquid storage section, and water is pre-stored in the liquid storage section. The liquid guide tube between the liquid storage section and the water collecting tank of the condensation device is the sealing section, and the sealing section is filled with a sealing liquid whose density is less than that of water and is insoluble in water.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0035] During the operation of the air conditioning system, the air conditioning unit will experience a variety of operating conditions according to different actual needs. Under these different operating conditions, the load and heat generation of the electrical components will change. Especially under high-load operating conditions, the electrical components will generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, the temperature of the electrical components will be too high, thus affecting their normal operation and life.

[0036] However, in some specific application scenarios, air conditioning units have higher requirements for the protection level of the electric control box. Such high-protection-level electric control boxes usually have better airtightness to ensure their reliability and safety in harsh environmental conditions. But this also brings a problem: due to the relative airtightness of the internal space of the electric control box, when the ambient temperature is low, the temperature difference between the inside and outside of the electric control box is large, which easily leads to condensation in the cabinet. This condensation not only affects the normal operation of electrical components, but also may pose a threat to the electrical safety performance of the product.

[0037] In hot and humid areas, the climate environment has stricter requirements on the heat dissipation and anti-condensation of the electric control box. Although the traditional air-cooled heat dissipation device can solve the heat dissipation problem to a certain extent, it is difficult to apply it directly due to the airtightness requirements of the high protection level electric control box. At the same time, although the installation of conventional drainage pipes can discharge the condensation water in the cabinet, it may also cause hot and humid air to enter the electric control box, thus failing to meet the protection level requirements.

[0038] Therefore, for electric control boxes with a higher protection level, how to ensure their heat dissipation performance under high load conditions and effectively prevent condensation in low temperature environments has become an urgent problem to be solved.

[0039] like Figure 1 As shown, the utility model proposes an anti-condensation device, including: a condensation device 3 and a liquid guide tube 5.

[0040] The condensation device 3 is arranged in the sealed box and is located on the air flow channel in the sealed box. The condensation device 3 converts the moisture in the air in the sealed box into condensation. A water collecting tank is arranged at the bottom of the condensation device 3, and the condensation finally falls into the water collecting tank. The liquid guide pipe 5 is connected to the water collecting tank of the condensation device 3 and is sealed by liquid, so that the condensation water generated by the condensation device 3 can be discharged. The liquid seal is arranged in the liquid guide pipe 5 to ensure that the condensation water in the sealed box is discharged while preventing the external air from entering the sealed box from the liquid guide pipe 5.

[0041] A fan 2 is arranged at the bottom of the sealed box, and an air flow channel is formed by the fan 2. The condensation device 3 is arranged in the sealed box and is located at the air outlet side of the fan 2. When the fan 2 is in operation, an air flow channel is formed, and the air in the sealed box can be blown to the condensation device 3, and the condensation device 3 converts the moisture in the air into condensation water. A water collecting tank is arranged at the bottom of the condensation device 3, and the condensation water converted by the condensation device 3 finally falls into the water collecting tank. One end of the liquid guide tube is connected to the water collecting tank of the condensation device, and the other end is connected to the outside and is lower in height than the end connected to the water collecting tank, and the height of the middle part of the liquid guide tube is lower than the height of the two ends.

[0042] The middle part of the liquid guide tube 5 is U-shaped or V-shaped. In this embodiment, the middle part of the liquid guide tube 5 is U-shaped and is arranged outside the closed box. One end of the liquid guide tube 5 is connected to the water collecting tank at the bottom of the condensation device 3, and the other end is connected to the outside and is lower than the condensation tube at the end connected to the water collecting tank. After the water in the water collecting tank enters the liquid guide tube 5, it can be discharged through the lower end of the liquid guide tube 5 due to the pressure difference. The liquid guide tube includes a sealing section and a liquid storage section. The middle part is the liquid storage section, and water is pre-stored in the liquid storage section. The liquid guide tube between the liquid storage section and the water collecting tank of the condensation device is a sealing section, and the sealing section is filled with a sealing liquid with a density less than water and insoluble in water. If the two ends of the liquid guide tube 5 are the same height or the end connected to the outside is larger than the end connected to the condensation device 3, it will cause the condensation water to be unable to be discharged from the condensation device 3 or flow back into the condensation device 3. The airflow path of the sealed box can be formed by other means besides by the fan 2, preferably by the fan 2, which can blow the air toward the condensation device 3 faster while forming the airflow path and cool the temperature inside the sealed box.

[0043] The bottom of the liquid conduit 5 is filled with pre-stored water. A sealing liquid with a density lower than that of water and insoluble in water is provided in the liquid conduit 5 between the water and the condensation device 3. The moisture in the air is converted into condensation by the semiconductor of the condensation device 3. The condensation flows into the liquid conduit 5 from the water collecting tank. Since the density of water is greater than that of the sealing liquid, the water sinks to the lower layer of the sealing liquid after entering the liquid conduit 5. After the condensation increases, it can flow out from the other end of the liquid conduit 5. Since the middle part of the liquid conduit 5 is U-shaped, the water pre-stored at the bottom of the liquid conduit 5 is always there to prevent the sealing liquid from flowing into the other end of the liquid conduit 5 and flowing out. The sealing liquid can also seal the liquid conduit 5 to prevent external gas from entering the sealed box from the liquid conduit 5.

[0044] The sealed box can be an electric control box 1. The electric control box 1 contains various electrical components and equipment, which have specific requirements for the working environment. In a humid environment, electrical equipment is prone to electrical line short circuit, insulation rupture and other problems, resulting in equipment damage or safety accidents. A fan 2 and a condensation device 3 are arranged in the electric control box 1. The fan 2 blows air toward the condensation device 3 to convert moisture in the air into condensation. The middle part of the liquid guide tube 5 is arranged in a U shape, one end of which is connected to the water collecting tank of the condensation device 3, and the other end is lower than the end connected to the condensation device 3, so that after the condensation water enters the liquid guide tube 5, it can be discharged from the lower end due to pressure. Water and sealing liquid are pre-stored in the pressure guiding tube, and the water in the electric control box 1 flows into the liquid guide tube 5 from the water collecting tank. Since the density of water is greater than the density of the sealing liquid, the condensation water sinks to the lower layer of the sealing liquid after entering the liquid guide tube 5. When the water in the liquid guide tube 5 gradually increases, the pressure will cause the condensation water to flow out from the lower end of the liquid guide tube 5. The sealing liquid completely seals the liquid guide tube 5 and is always between the water in the liquid guide tube 5 and the condensation device 3, preventing external air from entering the electric control box 1 from the liquid guide tube 5, ensuring that the inside of the electric control box 1 is completely sealed and condensation water can be discharged. Completely sealing the electric control box 1 can effectively prevent external moisture from entering, thereby protecting the equipment from damage and ensuring the normal operation and safety of the equipment. The fan 2 can also cool the inside of the electric control box 1 while blowing air to the condensation device 3, preventing the problem of damage to the electrical components inside the electric control box 1 due to excessive temperature.

[0045] A semiconductor is provided inside the condensation device 3, and semiconductor refrigeration is utilized. The semiconductor temperature is lower than the ambient temperature inside the sealed box. The humid air inside the sealed box passes through the low-temperature semiconductor, causing the gaseous water therein to condense into condensed water, which eventually flows into the water collecting tank at the bottom of the condensation device 3.

[0046] like Figure 1 As shown, the middle part of the liquid guiding tube 5 is U-shaped, and a second water level sensor for detecting the preset minimum water level is provided at the bottom. When the water in the liquid guiding tube 5 is equal to or less than the preset minimum water level, the control valve is opened to allow the water in the water collecting tank to flow into the liquid guiding tube 5, until the water level in the liquid guiding tube 5 is greater than the preset minimum water level, the control valve is closed to ensure that the sealing liquid in the liquid guiding tube 5 will not enter the other side of the liquid guiding tube 5 due to the low pre-stored water level in the liquid guiding tube 5, and flow out from the other end of the liquid guiding tube 5. The end of the liquid guiding tube 5 connected to the outside is bent downward to help the liquid guiding tube 5 to guide the condensed water.

[0047] The liquid guide pipe 5 is connected to the water collecting tank of the condensation device 3, and a control valve is provided at the connection point. The switch of the control valve can control the condensation of the condensation device 3 to flow into the liquid guide pipe 5. The control valve can be opened at any time to discharge the condensation water or closed to store the condensation water in the water collecting tank according to the demand. When the control valve is opened, the condensation flows from the condensation device 3 into the liquid guide pipe 5 and is discharged. When the control valve is closed, the condensation is stored in the water collecting tank of the condensation device 3. A third water level sensor for detecting a first preset water level and a fourth water level sensor for detecting a second preset water level are provided in the water collecting tank of the condensation device 3. The second preset water level is greater than the first preset water level. When the control valve is closed, the condensation water is stored in the water collecting tank of the condensation device 3. When the water in the water collecting tank reaches the second preset water level, the control valve is opened to drain the water. When the water in the water collecting tank is discharged to the first preset water level and the water in the liquid guide pipe 5 is greater than the minimum water level in the liquid guide pipe 5, the control valve is closed to stop the drainage.

[0048] When the water level in the liquid conduit 5 is lower than the preset minimum water level 8, the water collecting tank in the condensation device 3 needs to open the control valve at any water level to allow the water in the water collecting tank to flow into the liquid conduit 5, to prevent the pre-stored water level in the liquid conduit 5 from becoming low and the sealing liquid from flowing out from the other end of the liquid conduit 5. The setting of the control valve can control the discharge of condensed water at any time, to prevent the sealing liquid from entering the other end of the liquid conduit 5 due to too little water in the liquid conduit 5 or the condensed water in the water collecting tank from being too much, which affects the normal operation of the condensation device 3.

[0049] A first water level sensor is provided at a preset maximum water level 7 in the liquid conduit 5. The preset maximum water level 7 is provided at a side where the liquid conduit 5 and the condensation device 3 are connected. When the water in the liquid conduit 5 reaches the preset maximum water level 7, the first water level sensor sends a warning signal, indicating that the water level in the liquid conduit 5 is too high at this time, and the anti-condensation device may fail. The anti-condensation device stops running and is repaired in time to prevent the sealing liquid in the liquid conduit 5 from flowing back into the condensation device 3.

[0050] A second water level sensor is provided at the preset minimum water level 8 of the liquid guiding tube 5, a first water level sensor is provided at the preset maximum water level 7 of the liquid guiding tube 5, a third water level sensor is provided at the first preset water level in the water collecting tank of the condensation device 3, a fourth water level sensor is provided at the second preset water level in the water collecting tank, and an indicator light 4 is provided at sensors corresponding to different positions outside the sealed box, and the water level conditions in the water collecting tank and the liquid guiding tube 5 can be judged by the indicator light 4, so as to facilitate adjustment at any time. The utility model also includes a controller, which can receive water level signals sent by the first water level sensor, the second water level sensor, the third water level sensor and the fourth water level sensor, and control the switch of the control valve by the water level signal. A touch screen 6 is also provided outside the sealed box, and the touch screen 6 is connected to the controller, and the controller can be controlled by the touch screen to adjust the switch of the control valve. The touch screen can display the situation that the water level in the water collecting tank is too high or too low and the water level in the liquid guiding tube 5 is too high or too low. The staff can monitor the water level conditions in the water collecting tank and the liquid guiding tube 5 in real time.

[0051] Preferably, the sealing liquid is benzene, gasoline or ethyl acetate.

[0052] like Figure 1 As shown, the utility model also proposes an air-conditioning unit, including the anti-condensation device of the present application. The anti-condensation device is set corresponding to the electric control box 1 of the air-conditioning unit. The electric control box 1 of the air-conditioning unit using the anti-condensation device of the present application can ensure the sealing of the electric control box 1, and can discharge the condensation in the electric control box 1 without affecting the sealing effect of the electric control box 1, and can also dissipate heat for the electrical components in the electric control box 1. It solves the problem that when the existing electric control box 1 discharges condensation, the external air will enter the electric control box 1 from the drain pipe, affecting the sealing effect of the electric control box 1, causing the electrical components in the electric control box 1 to be damaged by moisture and affect the normal operation and safety of the equipment. The anti-condensation device of the present application ensures the sealing of the electric control box 1, and the fan 2 runs when condensation is discharged, which can not only effectively blow the wind to the condensation device 3, but also effectively dissipate heat for the electrical components in the electric control box 1, prevent the electrical components in the electric control box 1 from being damaged or short-circuited due to excessive temperature, and reduce electrical component failures.

[0053] like Figure 2-3 As shown, the utility model also proposes an anti-condensation control method using the air conditioning unit of the present application.

[0054] The specific steps include:

[0055] Obtain the temperature and humidity in the electric control box 1;

[0056] The speed of the fan 2 and the power of the condensing device are adjusted according to the temperature and / or humidity in the electric control box 1 to reduce the temperature and / or humidity in the electric control box 1 .

[0057] Specifically, a temperature sensor and a humidity sensor are provided in the electric control box 1. The controller of the air conditioner adjusts the corresponding speed of the fan 2 and the power of the condensing device according to the temperature and / or humidity in the electric control box 1 to reduce the temperature and / or humidity in the electric control box 1, thereby preventing the fan 2 speed from being too high or too low, and the condensing device power from being too high or too low, resulting in the inability to remove the condensation effect or excessive waste of energy.

[0058] The cooling levels are pre-set corresponding to different levels of fan 2 rotation speeds and different levels of condensing device powers, and the fan 2 rotation speed and the condensing device power are adjusted according to the temperature and / or humidity in the electric control box 1 to select the cooling level for adjustment.

[0059] For example, the controller is pre-set with multiple levels of cooling capacity, which are 1a, 1b, 1c, 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, 5a, 5b, 5c from small to large; each level of cooling capacity corresponds to different levels of fan 2 speed and different levels of condensing device power. The fan 2 speed levels are a, b, and c from small to large, and the larger the level, the greater the speed; the condensing device power levels are 1, 2, 3, 4, and 5 from small to large, and the larger the condensing device level, the greater the condensing device power, and the higher the condensing device conversion efficiency. When the cooling capacity is 1a, the fan 2 speed level is a, and the condensing device power is registered as 1; when the cooling capacity is 2a, the fan 2 speed level is a, and the condensing device power is registered as 2, and the rest of the cooling capacity is deduced by analogy. Then, according to the temperature and / or humidity in the electric control box 1, the cooling capacity level is selected to adjust the fan 2 speed and the condensing device power. To prevent the fan 2 speed and the condensing device power from being too high or too low, set the cooling level with different levels of fan 2 speed and different levels of condensing device power, and select the right cooling level according to the temperature and / or humidity to prevent energy waste or the problem of not being able to remove condensation. The cooling level corresponding to the temperature or humidity is the optimal cooling level, which can reduce the temperature or humidity without wasting energy. If the cooling level is too high, energy will be wasted, and if the cooling level is too low, the cooling and anti-condensation effects will be poor.

[0060] The cooling capacity, condensing device 3 power and fan 2 speed level correspond to the following table:

[0061]

[0062] like Figure 3 As shown, adjusting the speed of the fan 2 and the power of the condensing device according to the temperature and / or humidity in the electric control box 1 specifically includes:

[0063] When the humidity in the electric control box 1 is greater than or equal to the first preset humidity or the temperature is greater than the first preset temperature, if the current humidity or temperature has a corresponding cooling level, the cooling level is directly selected to switch the speed of the fan 2 and the power of the condensing device.

[0064] For example, when the humidity sensor detects that the humidity is greater than 40 or the temperature is greater than 50, the anti-condensation device starts to run, and the fan 2 and the condensing device 3 are turned on. The air conditioner controller determines that the current humidity or temperature has a corresponding cooling level. The controller controls the fan 2 and the condensing device to adjust to the fan 2 speed and the condensing device power corresponding to the cooling level according to the cooling level corresponding to the current humidity or temperature in the electric control box 1. This can effectively prevent condensation and excessive temperature from occurring in the electric control box 1, which will affect the service life of electrical components in the electric control box 1. Different humidity and temperature correspond to different levels of cooling, which effectively saves energy, prevents excessive cooling from wasting energy, and also prevents too little cooling from failing to prevent condensation.

[0065] The controller of the air conditioner will store the cooling capacity required under different temperature and humidity conditions. If the humidity in the electrical control box 1 is greater than or equal to the first preset humidity or the temperature is greater than or equal to the first preset temperature, the anti-condensation device will be operated, and the temperature or humidity will store the corresponding cooling capacity in the controller, and the fan 2 and the condensation device 3 will be directly controlled to adjust to the corresponding level to form the corresponding cooling capacity.

[0066] When the humidity in the electric control box 1 is greater than or equal to the first preset humidity or the temperature is greater than or equal to the first preset temperature, if the current humidity or temperature does not have a corresponding cooling capacity level, the cooling capacity level is gradually increased until the humidity or temperature in the electric control box 1 drops within the first time, and the corresponding relationship between the cooling capacity level and the current temperature or humidity is recorded. If the temperature or humidity in the electric control box 1 does not drop within the first preset time after the cooling capacity is adjusted to the maximum level, the temperature or humidity at this time is recorded in correspondence with the maximum cooling capacity level.

[0067] For example, when the humidity sensor detects that the humidity is greater than 40 or the temperature is greater than 50, the controller of the air conditioner determines that the current humidity or temperature has no corresponding cooling capacity level, and first controls the fan 2 and the condensing device to operate at the lowest cooling capacity level. If the humidity or temperature in the electric control box 1 drops within the first preset time, the controller records the cooling capacity level corresponding to the temperature or humidity at this time, and the fan 2 and the condensing device continue to operate at this level until the humidity in the electric control box 1 is less than the first preset humidity and the temperature is less than the first preset temperature;

[0068] If the humidity or temperature in the electric control box 1 does not drop within the first preset time, the controller controls the power of the fan 2 and the condensing device, and operates at the fan 2 speed level and the condensing device power level corresponding to the next level of cooling capacity, and repeats this process until the temperature or humidity in the electric control box 1 drops within the first preset time. The controller records the cooling capacity level corresponding to this temperature or humidity, and the fan 2 and the condensing device continue to operate at this level until the humidity in the electric control box 1 is lower than the first preset humidity and the temperature is lower than the first preset temperature, and the fan 2 and the condensing device stop running. Each time a temperature and / or humidity without corresponding cooling capacity is encountered, the controller records its temperature and / or humidity with the corresponding cooling capacity, and the next time the same temperature and / or humidity is encountered, it can directly execute according to the recorded cooling capacity, so as to avoid the need to adjust the cooling capacity step by step every time the anti-condensation device is turned on, which consumes a lot of time and energy.

[0069] The rotation speed of the fan 2 and the power of the condensing device are adjusted according to the temperature and / or humidity in the electric control box 1. Specifically, it also includes: when the humidity in the electric control box 1 is lower than the first preset humidity and the temperature is lower than the first preset temperature, the fan 2 and the condensing device 3 stop running, indicating that the temperature and humidity in the electric control box 1 meet the requirements at this time, and there is no need to turn on the fan 2 and the condensing device 3, which can save energy.

[0070] The utility model also proposes a readable storage medium for storing a computer program, and the anti-condensation control method of the utility model is executed when the computer program is running. In one or more embodiments, the described functions can be implemented in hardware, software, firmware or any combination thereof. If implemented as a computer program product in software, each function can be stored as one or more instructions or codes on a readable storage medium for transmission. The readable storage medium includes both computer storage media and communication media, which includes any medium that facilitates the transfer of a computer program from one place to another. The storage medium can be any available medium that can be accessed by a computer. As an example and not a limitation, such a readable storage medium may include RM, ROM, EEPROM, CD-ROM or other optical disk storage, disk storage or other magnetic storage device, or any other medium that can be used to carry or store a desired program code in the form of an instruction or data structure and can be accessed by a computer. Any connection is also properly referred to as a readable storage medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology such as infrared, radio, and microwave is included in the definition of medium. Disk and disc as used herein include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc, where disks tend to reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of readable storage media.

[0071] Compared with the prior art, the utility model proposes an anti-condensation device, including a condensation device 3 and a liquid guide tube 5. The condensation device 3 is arranged on the air flow channel of the sealed box, and can convert the gaseous water in the air in the sealed box into condensation water. The liquid guide tube 5 is connected to the condensation device 3 to guide the condensation water in the condensation device 3, and the liquid guide tube 5 is sealed by liquid to prevent the outside air from entering the sealed box while guiding the condensation water, which solves the problem that the outside air will enter the sealed box from the pipe for guiding the condensation water when the condensation water of the sealed box is guided out in the prior art, affecting the sealing of the sealed box. In addition, the present application provides a fan 2 in the sealed box to form a flow channel, which accelerates the rate at which the air flows to the condensation device 3 and reduces the temperature in the sealed box.

[0074] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0075] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0076] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
