[0005] Patent Document 2 "JP 2003-321175 (A)" discloses calling out of the elevator hall and the end of the car destination floor call service or the elevator is in a dormant state, and stopping the operation of the air cleaner after the predetermined time arrives, but fails to Taking into account the effect of the ventilation fan on the ion concentration, the efficiency of ion purification is maximized
[0006] Patent document 3 "CN103562114B" discloses installing an ion purifier at the air outlet of an elevator, but it does not consider that as a paid additional optional product, it should not affect the design of the standard product as much as possible, so as to facilitate production and installation and improve production efficiency
[0007] In addition, the free odor in the air is obviously easier to be perceived and disgusted by passengers than the attached odor and attached bacteria, but also in view of the deodorization principle of the ion generator, its efficiency in eliminating free odor is relatively slow. This outstanding contradiction is mentioned in the above literature also did not mention

Embodiment 1

[0072] Such as figure 1 As shown, the elevator includes a car and a ventilation system with ions, and the ventilation system with ions includes a passenger detection device 4, a memory, an ion generator 2, a blowing device, and a controller;

[0073] The passenger detection device 4 is used to detect the number of passengers in the car and send it to the controller;

[0074] The memory is provided with a table corresponding to the number of passengers and the required wind speed, and the required wind speed in the corresponding table is between the lowest set wind speed and the highest set wind speed;

[0075] The blowing device, in the service mode, operates at the required wind speed corresponding to the current number of passengers; in the leisure mode, operates at the lowest set wind speed when the ionizer 2 is started, and operates at the lowest set wind speed when the ionizer 2 is turned off. stop running;

[0076] The ion generator 2, in the service mode, starts and s...

Embodiment 2

[0080] Based on the elevator of embodiment one, such as figure 1 As shown, the working process of the controller is as follows:

[0081] 1. When the ventilation system with ions starts to work, the controller is initialized;

[0082] 2. judge whether described elevator is running, if running, go to step 3, otherwise go to step 4;

[0083] 3. The controller controls the ion generator to operate in service mode, and controls the blowing device to operate in service mode; enter step five;

[0084] 4. The controller controls the ion generator to operate in a leisure mode, and controls the blowing device to operate in a leisure mode; enter step five;

[0085] 5. Determine whether the ventilation system with ions is closed, if not, proceed to step 2, otherwise proceed to step 6;

[0086] 6. End.

Embodiment 3

[0088] Based on the elevator of the second embodiment, the ventilation system with ions also includes an odor sensor 5;

[0089] The odor sensor 5 is used to detect the odor in the car;

[0090] Such as image 3 As shown, set step A after step 1 and before step 2;

[0091] In step A, first judge whether the peculiar smell in the car exceeds the threshold value, if the peculiar smell in the car exceeds the threshold value, the controller controls the ion generator to operate in the service mode, and controls the blowing device to operate at the highest set wind speed Set the time, if the odor in the car does not exceed the threshold, go to step 2;

[0092] In step five, it is judged whether the ventilation system with ions is closed, and if not, proceed to step A.

[0093] Preferably, the set time is 1 minute.

[0094] Preferably, in the service mode, the ion generator starts for ten minutes and stops for five minutes.

[0095] Preferably, in the service mode, the ion gene...

Abstract

The invention discloses an elevator. According to the elevator, a passenger detection device is used for detecting the number of passengers in a car and sending the number of passengers to a controller; a storage device is provided with a corresponding table of required wind speed to the number of passengers, and the required wind speed in the corresponding table is between a lowest set wind speedand a highest set wind speed; a blowing device is used for running according to the required wind speed corresponding to the current number of passengers in a service mode; in a leisure mode, when anion generator is started, the blowing device runs at the lowest set wind speed, and the blowing device stops running when the ion generator is stopped; the ion generator is started and stopped in a circulation mode in the service mode, and starting time is longer than stopping time; in the leisure mode, the ion generator is started and stopped in a circulation mode, and the stopping time is longer than 2 times of the starting time; and the controller controls the blowing device and the ion generator to work in the service mode or the leisure mode according to whether the elevator runs or notand the number of passengers in the car. According to the elevator, the higher ion concentration is maintained as much as possible on the basis of ensuring fresh air volume in the car, and the maximization of the ion effect is realized.

Description

technical field [0001] The invention relates to elevator technology, in particular to an elevator with an ion generating device. Background technique [0002] In recent years, as people pay attention to the surrounding living environment, there are more and more demands and products for sterilization and deodorization in elevator cars. The filtering method is undoubtedly the most effective and convenient method, but it is limited by the installation space of the car roof and the high maintenance cost of consumables, so there are few corresponding actual products and applications. It is a better solution to install a purification device with an ion generator in the elevator. It is small and flexible, has no consumables, has a long life and low maintenance costs. [0003] In view of the antibacterial and deodorizing principles of ion generators, it is necessary to collide and chemically react with ions and pollutants to achieve results. Therefore, in order to achieve the ant...
